`
`DETAILED DESCRIPTION
`
`[Detailed Description of the Invention]
`
`[Field of the Invention]
`
`[0001]
`
`The present invention relates to the technology for illuminating the sample arranged
`
`in all directions from the back side, and improving visibility into the display space
`
`which started the light for automatic vending machines, especially was provided by
`
`the front face of the vending machine body.
`
`[Background of the Invention]
`
`[0002]
`
`Generally an automatic vending machine in the front face of an approximately
`
`box-shaped vending machine body A supplement of goods, The main door opened
`
`and closed in the cases, such as exchange, is provided, a transparent cover panel is
`
`provided in the upper part of this main door, a display space is formed inside this
`
`transparent cover panel, a predetermined interval is consisted in this display space,
`
`and two or more samples are arranged in all directions.
`
`[0003]
`
`In such an automatic vending machine, the light source for illuminating each sample is
`
`provided so that each sample can recognize visually sufficiently, even when installed
`
`

`

`in night or the shade. As a light source in this case, although the fluorescent lamp is
`
`used widely conventionally, the surface of the fluorescent lamp of a long life or a
`
`maintenance is insufficient.
`
`[0004]
`
`Therefore, in a prior art, use the LED lamp which arranges and carries out unitization
`
`of the many LED (light emitting diode) to array form with a predetermined pitch as a
`
`light source, and in the back side of a sample, Arrange the light guide plate in which
`
`much reflecting dots which consist of a minute protruding part were formed, and the
`
`above-mentioned LED lamp is arranged oppositely to one side edge of this light guide
`
`plate, After introducing the light from a LED lamp into a light guide plate, what makes
`
`it reflect by the reflecting dots of a light guide plate, and illuminated each sample is
`
`proposed (for example, following see Patent Document 1).
`
`[0005]
`
`In other prior arts, the thing which is arranged in a display space and which provides
`
`the reflector of LED and concave shape for every sample, concentrates a sample,
`
`and was illuminated uniformly is proposed (for example, following see Patent
`
`Document 2).

`
`[Description of the Invention]
`
`[Problem to be solved by the invention]
`
`[0006]
`
`However, although the light guide plate for introducing the light from a LED lamp and
`
`illuminating a sample is used in the prior art of the former Patent document 1
`
`description, Since this light guide plate applies the transparent member made from
`
`plastics, such as glass and an acrylic resin, Since the light guide plate itself needs to
`
`form much reflecting dots which consist of a protruding part heavy and minute on the
`
`back side of the weight of the whole automatic vending machine not only increasing
`
`but a light guide plate, processing of a light guide plate takes time and effort, and it
`
`will become expensive. And since the inside of a display space will be illuminated
`
`generally, the portion by which the sample is not arranged also has the problem that
`
`it is illuminated simultaneously, and becomes bright and the visibility of a sample
`
`becomes insufficient.
`
`[0007]
`
`In the prior art of the latter Patent document 2 description, Since LED and a
`
`reflector are provided for every sample and it is necessary to provide LED and a
`
`

`

`reflector individually to each sample of what can concentrate a sample, can illuminate
`
`uniformly and can improve visibility, On the whole, structure is complicated and there
`
`is a problem of becoming expensive.
`
`[0008]
`
`The the object of this invention is as follows.
`
`It was made in order to solve the above-mentioned problem, and illuminate each
`
`sample uniformly.
`
`Improve the visibility of each sample and provide a light for automatic vending
`
`machines which can be inexpensive manufactured as it is moreover also at an easy
`
`structure.
`
`[Means for solving problem]
`
`[0009]
`
`To achieve the above objects, the light for automatic vending machines concerning
`
`the invention according to claim 1, The planate diffusion panel by which close
`
`arrangement was carried out to two or more samples arranged in all directions, The
`
`planate reflective sheet which opposed to the back surface of the opposite side the
`
`arrangement side of the aforementioned sample of this diffusion panel, and is
`
`arranged, It has a light source arranged at both the 1 side-edge side of the
`
`aforementioned diffusion panel and a reflective sheet, and the aforementioned
`
`reflective sheet is characterized by inclining so that it may gradually decrease
`
`according to distance with the aforementioned diffusion panel separating from a light
`source.
`
`[0010]
`
`The light for automatic vending machines concerning the invention according to claim
`
`2 is characterized by forming the aforementioned reflective sheet so that it may
`
`become largely gradually according to the reflectance separating from the
`
`aforementioned light source in the constitution of the invention according to claim 1.
`
`[0011]
`
`The light for automatic vending machines concerning the invention according to claim
`
`3 is carrying out that the reflecting member is provided by the part which partitions a
`
`sample up and down at least to the aforementioned diffusion panel with the
`
`characteristics in the constitution of the invention according to claim 1 or 2.
`
`[0012]
`
`The light for automatic vending machines concerning the invention according to claim
`
`4 is characterized by the aforementioned reflecting member being provided by the
`
`

`

`outside surface by the side of arrangement of the aforementioned sample of the
`
`aforementioned diffusion panel in the constitution of the invention according to claim
`
`3.
`
`[Effect of the Invention]
`
`[0013]
`
`According to the present invention, while the diffusion panel was transmitted directly
`
`and the sample glared, after being reflected with a reflective sheet, the light from a
`
`light source transmits a diffusion panel, and is irradiated by the sample. In that case,
`
`since the reflective sheet inclines so that it may gradually decrease according to
`
`distance with a diffusion panel separating from a light source, the reflected amount of
`
`the light by a reflective sheet increases, so that it separates from a light source.
`
`Thereby, regardless of the distance from a light source, each sample can be
`
`illuminated uniformly. And since a light is an easy structure provided with the light
`
`source, the reflective sheet, and the diffusion panel, it becomes possible to
`
`manufacture inexpensive. The light itself becomes a lightweight thin shape and it
`
`becomes easy to secure goods storage space.
`
`[0014]
`
`In particular, in the invention according to claim 2, since it is formed so that the
`
`reflectance of a reflective sheet may become largely gradually according to
`
`separating from a light source, a still more uniform luminescent surface is acquired
`
`and each sample can be further illuminated to homogeneity.
`
`[0015]
`
`In the invention according to claim 3, since the reflecting member is provided by the
`
`part which partitions a sample up and down at least, on a diffusion panel, the inside of
`
`a display space will not be illuminated generally, but a sample will be intensively
`
`illuminated on it. For this reason, the contrast of the arrangement part of a sample
`
`and the other part becomes clear, and the visibility of each sample becomes high.
`
`[0016]
`
`In the invention according to claim 4, since the reflecting member is provided by the
`
`outside surface by the side of arrangement of the aforementioned sample of a
`
`diffusion panel, the light which carries out the light guide of the inside of a diffusion
`
`panel leaking and appearing in the portion by which the sample is not arranged, and
`
`becoming bright is avoided. As a result, a sample can be illuminated still more
`
`intensively and the visibility of each sample can be improved further.
`
`[Best Mode of Carrying Out the Invention]
`
`[0017]
`
`

`

`Hereafter, with reference to Drawings, it describes in detail about an embodiment of
`
`the invention. The front view of the automatic vending machine in which the light for
`
`automatic vending machines of the present invention was applied to Eigl, the front
`
`view in which Fig.2 expands and shows the portion of the light of the automatic
`
`vending machine, and Fig.3 are the cross sectional views which were along the A-A
`
`line of Fig.2.
`
`[0018]
`
`In this embodiment, the main door 3 by which the automatic vending machine 1
`
`is
`
`opened and closed by the front face of the approximately box-shaped vending
`
`machine body 2 in the cases, such as a supplement of goods and exchange, is
`
`provided, and the transparent cover panel 4 is provided by the upper front of this
`
`main door 3. And the display space 5 is formed inside this transparent cover panel 4,
`
`and two or more samples 6 are arranged in all directions in this display space 5. That
`
`is, after the sample 6 consisted the predetermined interval in the display space 5 and
`
`having been arranged by conformity in two or more, it provides over two or more
`
`steps of upper and lower sides. Each sample 6 is what was able to do article shapes
`
`from the light transmitting property material molded by imitating, and the brand is
`
`shown here by the surface.
`
`[0019]
`
`The commodity selection push button 7 is provided individually at the lower end side
`
`of each sample 6, and rather than the transparent cover panel 4 of the main door 3,
`
`below the coin slot 8, the bill slot 9, and the change return port 10 are provided, and
`
`the commodity output port 11 is further provided by the lower part.
`
`[0020]
`
`The light 20 is provided by the back side of the sample 6. This light 20 is provided
`
`with the light source 21, the diffusion panel 22, the reflective sheet 23, and the
`
`reflecting member 24, and is stored in the housing 27 in which this light 20 consists
`
`of the transparent cover panel 4 of the wrap above the front sides of the
`
`approximately box-shaped case 26 in which the front carried out the opening, and
`
`this case 26. In this case, towards the transparent cover panel 4 side, the
`
`transparent cover panel 4 of the case 26 and the back part which opposes incline,
`
`and is formed.
`
`[0021]
`
`The above-mentioned light source 21 is arranged at the position slightly separated
`
`up in the housing 27 rather than upper one end of the diffusion panel 22 and the
`
`reflective sheet 23. This light source 21 comprises a LED lamp which arranges and
`
`

`

`carries out unitization of the many LED21b to array form with a predetermined pitch
`
`on the circuit board 21a extended along the cross direction of the housing 27.
`
`[0022]
`
`The diffusion panel 22 approaches the sample 6 and is arranged, and by processing of
`
`sandblasting etc., this diffusion panel 22 forms minute unevenness in the surface of
`
`the plate made from plastics, such as an acrylic resin, and is constituted, for example.
`
`[0023]
`
`The reflective sheet 23 is provided by the diffusion panel 22 in the case 26, the back
`
`face which opposes, and the right and left side edge, respectively. Therefore, the
`
`diffusion panel 22 and the reflective sheet 23 of the back side in the position which
`
`opposes incline so that it may gradually decrease according to distance with the
`
`diffusion panel 22 separating from the light source 21. And for example, pasting or
`
`aluminum foil is given to the inner surface of the case 26, this reflective sheet 23
`
`performs aluminum vapor deposition to pasting or the inner surface of the case 26
`
`directly, and the inner surface of the case 26 constitutes what applied the white
`
`coating to the sheet made from plastics, such as an acrylic resin.
`
`[0024]
`
`The strip—like reflecting member 24 which is a part which partitions a sample up and
`
`down, and is extended to the outside surface by the side of arrangement of the
`
`sample 6 along the cross direction of the housing 27 is joined to the
`
`above-mentioned diffusion panel 22. And each of these reflecting member 24 applies
`
`a white coating to the thin walled sheet of products made from a plastic, such as an
`
`acrylic resin, for example, or sticks aluminum foil and is constituted.
`
`[0025]
`
`In the light 20 of the above-mentioned composition, while the diffusion panel 22 was
`
`transmitted directly and the sample 6 glared, after being reflected by the inner
`
`surface of the reflective sheet 23, the light from the light source 21 transmits the
`
`diffusion panel 22, and is irradiated by the sample 6. In that case, since the reflective
`
`sheet 23 inclines so that it may gradually decrease according to distance with the
`
`diffusion panel 22 separating from the light source 21, the reflected amount of the
`
`light by the reflective sheet 23 increases, so that it separates from the light source
`
`21. Thereby, regardless of the distance from the light source 21, each sample 6 can
`
`be illuminated uniformly.
`
`[0026]
`
`Since the reflecting member 24 isjoined to the diffusion panel 22 by the part which
`
`partitions the sample 6 up and down and these reflecting members 24 are moreover
`
`

`

`provided by the outside surface of the diffusion panel 22, The light which the light
`
`which transmitted the diffusion panel 22 is reflected towards an inner direction by
`
`these reflecting members 24, and carries out the light guide of the inside of the
`
`diffusion panel 22 is also reflected by this reflecting member 24. For this reason, light
`
`leaking and appearing in the portion by which the sample 6 is not arranged too much,
`
`and becoming bright is avoided. By this, the inside of the display space 5 cannot be
`
`illuminated generally, but the sample 6 can be illuminated intensively, the contrast of
`
`the arrangement part of the sample 6 and the other part becomes clear, and the
`
`visibility of each sample 6 can be improved further.
`
`[0027]
`
`Since this light 20 is an easy structure which provided the light source 21, the
`
`reflective sheet 23, and the diffusion panel 22 in the housing 27, it becomes possible
`
`to manufacture inexpensive. While light 20 the very thing becomes a lightweight thin
`
`shape, it becomes possible to secure goods storage space easily to the back side
`
`lower part of the housing 27.
`
`[0028]
`
`About the diffusion panel 22 and the reflective sheet 23 in the position which
`
`opposes, when forming so that the reflectance may become largely gradually
`
`according to separating from the light source 21 carries out uniform illumination of
`
`each sample 6, it is much more preferable.
`
`[0029]
`
`As an example, as shown in Ejgfi, the reflectance of the reflective sheet 23 can be
`
`changed to the three-stage of the portion 230 of low reflectance, the portion 23b of
`
`inside reflectance, and the portion 23a of high reflectance according to separating
`
`from the light source 21. Adjustment of the reflectance of each part 23a-23c in this
`
`case, For example, when considering it as a reflective surface by applying a white
`
`coating and forming many circular dot patterns 29, as shown in fig, high reflectance
`
`-- obtaining -- largely (refer to the figure (a)), a diameter is carried out in inside
`
`reflectance and a diameter is made the smallest for the diameter of the dot pattern
`
`29 with (the Drawing (b) reference) and low reflectance in the middle at a degree
`
`(refer to the figure (0)). Or the distance between contiguity of each dot pattern 29
`
`can be small set up by enlarging most with low reflectance to a degree in the middle
`
`with inside reflectance with high reflectance.
`
`[0030]
`
`If it does in this way, a luminescent surface still more uniform than the case of the
`
`above-mentioned embodiment is acquired, and even when applying the light 20 to a
`
`

`

`large-sized automatic vending machine especially, it becomes possible to illuminate
`
`each sample 6 to homogeneity further, and visibility can be improved.
