Description

The present invention relates to a decorative panel used in a vending machine that sells products containing, for example, paper packs, cans, bottles, and plastic bottles, and a vending machine using the same.

  In general, this type of vending machine includes a vending machine main body with an open front and an outer door that opens and closes the front of the vending machine main body. , A coin insertion slot, a bill insertion slot, a coin return slot, a coin return lever, a product outlet, and the like are provided. Further, in this vending machine, the product sample room is illuminated so that the product sample can be easily displayed to the user even in a dark place, thereby enhancing the sales promotion effect.

  By the way, in recent years, as measures against global warming, efforts have been made to reduce power consumption and reduce carbon dioxide emissions. However, vending machines with a power saving function have been proposed. For example, a human sensor is provided to detect the user, and when the user is not detected by the human sensor, the product sample chamber is turned off or the product sample chamber lighting switch is not operated by the user Is known to save electricity by turning off the product sample chamber, such as turning off the illumination lamp (see, for example, Patent Document 1 or 2).

  However, if the product sample room is turned off when the vending machine is not in use, the user may not notice the presence of the vending machine in a dark place or misidentifies that the vending machine is not in operation. In some cases, sales opportunities may be missed by turning off the product sample room.

  Therefore, even when the product sample room is turned off, an LED with low power consumption is used to shine around the coin slot (see, for example, Patent Document 3), or any character or figure on the money amount display Is displayed (for example, refer to Patent Document 4) to indicate that the vending machine is in an operating state, but it is not always sufficient, and it is mistaken that the vending machine is not in an operating state. There was a case.

  By the way, in the illuminating device using the LED as described above, the light is incident on the end surface of the light guide member made of a transparent acrylic plate so that the light is incident and emitted from the other end surface. Since it is a point light source, it is difficult to scatter light, and it is difficult to uniformly emit light at the emission end face over a wide range. For this reason, there existed a problem that the light emission range narrowed and the display effect of an operation state was reduced. Further, when the emission end face is formed over a wide range, there is a problem that unevenness of light emission occurs and the appearance is impaired.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a decorative panel capable of evenly emitting LED light over a wide range even when the LED is used as a light source, and the decorative panel. Is to provide a vending machine using

In order to achieve the above object, the decorative panel of the present invention has a light guide member formed in a plate shape, a first reflecting surface and a second light reflector facing each other at a predetermined interval in the thickness direction of the light guide member . And an LED disposed so that the light emitting surface faces either the first reflecting surface or the second reflecting surface, and one end surface of the light guide member is connected to the first reflecting surface and the first reflecting surface. The light guide member is arranged so as to face between the two reflection surfaces, and reflects the light of the LED between the first reflection surface and the second reflection surface, and from between the first and second reflection surfaces. The light emitting surface of the LED is configured so that the distance from the center of the light emitting surface of the LED to the end surface on the incident side of the light guiding member is The distance is from 2 to 3 times the distance from the first reflecting surface to the first reflecting surface . .

As a result, the light from the LED is irradiated toward the first reflecting surface or the second reflecting surface, and after being dispersed while being repeatedly reflected between the first reflecting surface and the second reflecting surface, The light is emitted outward from between the first and second reflecting surfaces. In this case, the distance from the center of the light emitting surface of the LED to the end surface on the incident side of the light guide member is not less than 2 times and not more than 3 times the distance from the light emitting surface of the LED to the first reflecting surface or the second reflecting surface. By doing so, the emission end face of the light guide member emits light uniformly.

According to the present invention, since the light of the LED can be dispersed between the first reflecting surface and the second reflecting surface, even when the LED is used as a light source, the LED light is uniformly distributed over a wide range. In addition, it is possible to obtain an optimum configuration for emitting light uniformly on the emission end face of the light guide member .

It is connected to.

  The extending portion 42 is made of a synthetic resin transparent portion that is integrated with the panel main body portion 41, and extends toward one side and the lower side of the panel main body portion 41. In this case, the part extending to one side and the part extending downward are formed in an apron shape so as to be continuous with each other, and the peripheral edge of the corner is curved in a curved shape. Further, the extending portion 42 is formed with a portion extending downward except for one end side in the width direction of the panel main body portion 41, and the bill insertion slot 23 below the one end side in the width direction of the panel main body portion 41. Is arranged so as to be adjacent to the downwardly extending portion of the extending portion 42.

  Each LED 43 is composed of a chip-type LED in which the height dimension H in the direction perpendicular to the light emitting surface 43a is smaller than the width dimension W and the depth dimension D perpendicular to the height dimension H, as shown in FIGS. For example, it emits blue light.

  The substrate 44 is made of a printed circuit board on which one of the LEDs 43 is mounted, and is disposed so as to face the inner surface of the panel main body 41. In this case, the substrate 44 is formed so as to exclude one end in the width direction of the panel main body 41 on which the display device 29 is disposed and a circular portion corresponding to each of the recesses 41b and 41c. Each LED 43 on the substrate 44 is arranged at a plurality of positions on the edge of the panel main body 41 along the extending portion 42 at intervals, and between the first concave portion 41b and the second concave portion 41c. It is also arranged at multiple locations. In addition, a spacer 45 extending along the extending portion 42 is provided between the substrate 44 and the panel main body portion 41. In this case, the peripheral end of the spacer 45 is located inside the peripheral end of the substrate 44, and the LED 43 for the extending part 42 is disposed between the peripheral end of the substrate 44 and the spacer 45.

As shown in FIG. 5, the panel main body 41 and the extension 42 are formed in a plate shape having a thickness dimension Y 1, and the inner surface of the extension 42 is more than the inner surface of the panel main body 41. A step is formed by the thickness of the extending portion 42 so as to be lower than the front surface. A substrate 44 is arranged in the space in the panel main body 41 due to the step, and a gap is provided between the inner surface of the panel main body 41 and one surface of the substrate 44 by the spacer 45. In this case, the end surface of the spacer 45 is inclined so as to form a predetermined angle (for example, 45 °) with respect to one surface of the substrate 44, and the end surface of the spacer 45 and the inner surface of the panel main body 41 are each reflective plate 46 ( For example, it is covered with aluminum foil). One surface of the substrate 44 is formed in a light reflective color (for example, white). As a result, the first reflecting surface 47 is formed by one surface of the substrate 44, and the second reflecting surface 48 facing the first reflecting surface 47 is formed by the reflecting plate 46 on the inner surface side of the panel main body 41. Has been. The LED 43 is mounted on the first reflecting surface 47, and the LED 43 is disposed with the light emitting surface 43 a facing the second reflecting surface 48. In this case, the distance Y2 in the thickness direction of the extending portion 42 from the light emitting surface 43a to the second reflecting surface 48 of the LED43 is 1 times or less is preferably 1/3 or more the thickness Y1 of the extending portion 42 . A third reflecting surface 49 that is inclined with respect to the first reflecting surface 47 is formed by the reflecting plate 46 on the end surface side of the spacer 45.

  Further, due to the step between the panel main body 41 and the extending portion 42, the end surface of the extending portion 42 forms an incident end surface 42 a that faces the end portions of the first and second reflecting surfaces 47 and 48. As shown in FIG. 9, the light of the LED 43 reflected by the reflecting surfaces 47, 48, and 49 is incident on the incident end surface 42a. In this case, since the LED 43 is disposed with the light emitting surface 43a facing the second reflecting surface 48, after the light of the LED 43 is repeatedly reflected between the first reflecting surface 47 and the second reflecting surface 48, The light enters the incident end face 42a. Further, the light irradiated on the opposite side of the incident end face 42 a is reflected by the third reflecting surface 49 toward the incident end face 42 a. The distance X2 in the extending direction of the extending portion 42 from the center of the light emitting surface 43a of the LED 43 to the incident end surface 42a is the thickness direction of the extending portion 42 from the light emitting surface 43a of the LED 43 to the second reflecting surface 48. The distance Y2 is preferably not less than 2 times and not more than 3 times.

  Further, an outgoing end face 42b is formed at the peripheral edge of the extended portion 42 so as to be inclined at a predetermined angle (for example, 45 °) with respect to the surface of the extended portion 42. As shown in FIG. The light incident on the end surface 42a is guided by the extending portion 42 and is emitted to the outside from the emission end surface 42b. In this case, the exit end face 42b is processed into a rough surface such as a texture, a satin finish, or a hairline, and the exit end face 42b shines when light is irregularly reflected. In addition, a bent portion 42c that bends toward the inner surface side of the extended portion 42 is provided at the peripheral portion of the extended portion 42, and the thickness dimension X1 of the bent portion 42c is the thickness dimension Y1 of the extended portion 42. Is smaller than

  In the vending machine configured as described above, during the normal sales operation, the character “sold” is lit on the display 29, and it is displayed to the user that it can be sold. Here, when a user inserts a coin into the coin insertion slot 24 and an arbitrary product selection switch 22 is pressed, the product carry-out device 36 of the product storage column 35 storing the corresponding product is operated, and the product storage column 35 is operated. Are delivered to the product outlet 27. Further, when the return lever 26 is operated before the product selection switch 22 is pressed, the inserted coin is returned to the coin return port 25. In addition, when the banknote has been inserted into the banknote insertion slot 23, when the return lever 26 is operated, the banknote is returned to the banknote insertion slot 23.

  In the vending machine, for example, when the user is not detected by a human sensor (not shown), or in a predetermined time zone when there are few users, the illumination lamp 21b of the product sample chamber 21 is turned off. . At that time, in the decorative panel 40, as shown in FIG. 11, not only the “sale” characters are turned on by the indicator 29, but also the peripheral portions of the extending portions 42 and the coin slot 24 are turned on by turning on the LEDs 43. And the circumference | surroundings of the coin return lever 26 each light-emit (the black coating part of FIG. 11 shows a light emission part).

  That is, in the extension part 42, as shown in FIG. 9, the light incident on the incident end face 42a is guided by the extension part 42 and emitted to the outside from the emission end face 42b. No light is emitted between 42a and the emission end face 42b, and only the peripheral edge portion (outgoing end face 42b) of the extension 42 emits light in a line shape. In this case, the light of the LED 43 is irradiated toward the second reflecting surface 48 and is dispersed in the width direction of the incident end surface 42 a while being repeatedly reflected between the first reflecting surface 47 and the second reflecting surface 48. After that, since the light is emitted from between the first and second reflecting surfaces 47 and 48 toward the incident end surface 42a of the extending portion 42, the emitting end surface 42b emits light uniformly along the periphery of the extending portion 42. .

  On the other hand, the light of the LED 43 disposed in the vicinity of the first recess 41b and the second recess 41c is transmitted through the inner peripheral surfaces 41b-1 and 41c-1 of the recesses 41b and 41c, and in the recesses 41b and 41c. The light in the recesses 41b and 41c is reflected by the inner peripheral surfaces 41b-1 and 41c-1 by the surface layer 41a. In that case, since each inner peripheral surface 41b-1, 41c-1 forms a circumferential surface, the light is repeatedly reflected by each inner peripheral surface 41b-1, 41c-1, as shown in FIG. The whole of 41b-1 and 41c-1 is illuminated so as to emit light in a ring shape.

Moreover, when the test of Examples 1-2 and Comparative Examples 1-3 of this invention was done about the light emission uniformity of the peripheral part (output end surface 42b) of the extension part 42, the result of FIG. 12 was obtained. Here, the direction of the light emitting surface 43a of the LED 43 is such that Examples 1 and 2 are perpendicular to the first and second reflecting surfaces 47 and 48 as in the above embodiment, and Comparative Example 1 is the first and second directions. The direction was parallel to the reflecting surfaces 47 and 48 (perpendicular to the incident end face 42a). A first reflecting surface 47 a distance Y3 between the second reflecting surface 48, none of Comparative Example 1 and Example 1-2 was 3.5 mm. The height H of the LED 43 in the direction perpendicular to the substrate 44 was 0.4 mm in Comparative Example 1 and Example 1, and 1 mm in Example 2 and Comparative Examples 2-3 . The distance Y2 (= Y3 -H) from the light emitting surface 43a of the LED 43 to the second reflecting surface 48 is 3.1 mm in Comparative Example 1 and Example 1, 2.5 mm in Example 2 and Comparative Examples 2-3. did. The distance L from the center of the light emitting surface 43a of the LED 43 to the end of the substrate 44 was 7 mm in Comparative Example 1 and Examples 1-2, 3 mm in Comparative Example 2 , and 1 mm in Comparative Example 3 . The distance from the end of the substrate 44 to the incident end surface 42a is 0.5 mm, and the distance X2 (= L + 0.5) from the center of the light emitting surface 43a of the LED 43 to the incident end surface 42a is Comparative Example 1 and Example 1. -2 was 7.5 mm, Comparative Example 2 was 3.5 mm, and Comparative Example 3 was 1.5 mm.

In this test, the LED 43 is lit in a place where the surroundings are dark, and whether or not the emission end face 42b of the extending part 42 in Comparative Examples 1 to 3 and Examples 1 and 2 emits light uniformly along the peripheral edge is visually checked. And the light emission uniformity was evaluated by an index with Comparative Example 1 being 100. In this case, the higher the index value, the more superior.

As a result of the test, the comparative example produced light emission unevenness in which a difference in brightness partially occurred along the peripheral edge of the extended portion 42, but Example 1 had no light emission unevenness and the light emission uniformity was the best. Results were obtained. In addition, comparative examples 2 to 3 showed slight emission unevenness, but in Example 2, the result that there was almost no emission unevenness was obtained.

The ratio of the distance X2 from the center of the light emitting surface 43a of the LED 43 to the incident end face 42a and the distance Y2 from the light emitting surface 43a of the LED 43 to the second reflecting surface 48 is 2.4: 1 in Example 1. Since Example 2 is 3: 1, Comparative Example 2 is 1.4: 1, and Comparative Example 3 is 0.6: 1, X2: Y2 is 2.4: 1 of Example 1 from the above test results. Optimum, preferably, X2 is not less than 2 times and not more than 3 times Y2.

  Further, the distance Y2 in the thickness direction of the extending portion 42 from the light emitting surface 43a of the LED 43 to the second reflecting surface 48 is such that the extending portion 42 is between the incident end surface 42a and the emitting end surface 42b of the extending portion 42. If it is smaller than 1/3 of the thickness dimension Y1, the amount of light incident on the incident end face 42a is insufficient, and if it is larger than 1 time, the light of the LED 43 leaks to other than the incident end face 42a, so Y2 is 1/3 of Y1. It is preferably 1 to 1 time.

  As described above, according to the decorative panel 40 for a vending machine of the present embodiment, the panel main body 41 having a non-transparent surface, and the panel main body 41 extends outward along the surface of the outer door 20. A transparent extension portion 42 and an LED 43 provided in the panel main body portion 41, and the panel main body portion 41 is opposed to each other with an interval in the thickness direction of the panel main body portion 41. And the LED 43 is arranged on the first reflecting surface 47 so that the light emitting surface 43a faces the second reflecting surface 48, and the light from the LED 43 is transmitted to the first and second reflecting surfaces. Since the light is repeatedly reflected by 47 and 48 and enters the extended portion 42 from the end portions of the first and second reflecting surfaces 47 and 48, and is emitted to the outside from the peripheral portion of the extended portion 42. Light is transmitted between the first and second reflecting surfaces 47 and 48. After being reflected and dispersed in the width direction of the incident end face 42a, the light can be emitted from between the first and second reflecting faces 47 and 48 toward the incident end face 42a. Light can be emitted uniformly along the peripheral edge of the extension 42. Thereby, the peripheral part of the extension part 42 can be made to emit light over a wide range without causing uneven light emission, and the display of the operating state of the vending machine by the light emission of the extension part 42 can be easily confirmed even in a dark place. be able to. Therefore, the sales promotion effect can be enhanced without missing the sales opportunity to the user.

  In this case, as the LED 43, a LED having a height dimension H in a direction perpendicular to the light emitting surface 43a smaller than dimensions W and D in a direction perpendicular to the height dimension is used. The interval Y3 of 48 can be reduced, which is extremely advantageous for making the panel body 41 thin.

  Further, since the third reflecting surface 49 that is inclined with respect to the first and second reflecting surfaces 47 and 48 is provided in the vicinity of the LED 43, the LED 43 is arranged so that the light emitting surface 43 a faces the second reflecting surface 48. Even if arranged, the light irradiated on the opposite side of the incident end face 42a can be reflected by the third reflecting surface 49 toward the incident end face 42a (the first and second reflecting faces 47 and 48), and extended. There is an advantage that the amount of light to the portion 42 side is not reduced.

  Further, a distance X2 in the extending direction of the extending portion 42 from the center of the light emitting surface 43a of the LED 43 to the incident end surface 42a of the extending portion 42 is defined as an extending portion from the light emitting surface 43a of the LED 43 to the second reflecting surface 48. By making the distance Y2 in the thickness direction 42 to be not less than 2 times and not more than 3 times, it is possible to obtain an optimum configuration for uniformly emitting the emission end face 42b of the extending portion 42 along the peripheral edge portion.

  Further, the distance Y2 in the thickness direction of the extending portion 42 from the light emitting surface 43a of the LED 43 to the second reflecting surface 48 is set to the distance between the incident end surface 42a and the emitting end surface 42b of the extending portion 42. By setting the thickness dimension Y1 to 1/3 times or more and 1 time or less, it is possible to obtain an optimum configuration for allowing the light of the LED 43 to enter the extending portion 42 efficiently.

  Further, the panel body 41 is provided with a first recess 41b in which the coin slot 24 is disposed and a second recess 41c in which the return lever 26 is disposed, and an inner peripheral surface 41b− of each recess 41b, 41c. 1, 41c-1 is formed so as to transmit light from the inside to the outside of the panel main body 41 and reflect light from the outside, and the light of the LED 43 in the panel main body 41 is transmitted to each of the recesses 41b and 41c. Since the light is emitted from a predetermined location in the circumferential direction of the inner peripheral surfaces 41b-1 and 41c-1 to other locations, the light is repeatedly reflected by the inner peripheral surfaces 41b-1 and 41c-1, and each inner periphery It can illuminate so that the whole surface 41b-1, 41c-1 may light-emit in a ring shape, and the display effect of the operating state of a vending machine can be heightened with the light emission of the peripheral part of the extension part 42. Even when the surroundings are dark and the product sample chamber 21 is turned off, the positions of the coin slot 24 and the return lever 26 can be easily confirmed by the illumination of the recesses 41b and 41c. And return operations can be performed reliably.

  In the above-described embodiment, the panel body portion 41 is provided with the coin insertion slot 24, the coin return lever 26, and the indicator 29. However, only one of the coin insertion slot 24 and the coin return lever 26 is provided. Alternatively, the bill insertion slot 23, the advertisement display unit, and the like may be arranged on the panel main body 41.

  Further, in the above-described embodiment, the first and second reflecting surfaces 47 and 48 that face each other at an interval and the light emitting surface 43 a are arranged on the first reflecting surface 47 so as to face the second reflecting surface 48. LED 43, and the light emitted from the LED 43 is repeatedly reflected by the first and second reflecting surfaces 47 and 48 and emitted from the end portions of the first and second reflecting surfaces 47 and 48 to the outside. Although what used the apparatus for the decorative panel 40 of the vending machine was shown, the illuminating device of this invention can be used as various illuminating devices, such as apparatuses other than a vending machine, interior, furniture, etc., for example.

  Furthermore, in the above-described embodiment, the exit end face 42b of the extending portion 42 is processed into a rough surface such as a texture or a satin finish. For example, as shown in FIG. 13 (a), the surface of the exit end face 42b is shown. A large number of pyramidal or conical protrusions 42b-1 may be provided on the surface, or a large number of prismatic or columnar protrusions 42b-2 may be provided as shown in FIG. 13 (b). . Further, as shown in FIG. 13C, a stepped uneven portion 42b-3 may be provided on the surface of the emission end face 42b.

  In the above embodiment, the surface layer 41a is formed by vapor-depositing paint on the surface of the panel main body 41. However, if the paint is vapor-deposited on the back surface of the panel main body 41, the surface layer 41a is formed. There is an advantage that the vapor deposition surface is not damaged by scratches or dirt on the surface of the panel body 41.

  Further, in the above-described embodiment, the first reflecting surface 47 and the second reflecting surface 48 are opposed to each other in parallel. However, the distance between the first and second reflecting surfaces 47 and 48 is different.
