Abstract

PURPOSE:To obtain an automatic vending machine looking nice where a light source is not seen from the external by providing a thin exposure device provided with a diffuse transmission member having specific reflection bodies and a light-transmissive display device. CONSTITUTION:A thin exposure device 15 is provided where a diffuse transmission member 12 having dot-shaped or narrow linear reflection bodies 11, whose density is higher in the shorter distance from a light source 13, is provided between the light source 13 and an exposure face. The light from the light source 13 is reflected by reflection bodies 11 applied on the diffuse transmission member 12, and the degree of this reflection is larger in the vicinity of the light source 13 where the density of reflection bodies 11 is higher, and this light is reflected by the inside surface of the thin exposure device 15 again and reaches the diffuse transmission member 12. Consequently, the luminance of the exposure face of the thin exposure device 15 is uniform, and all of the surface of a light-transmissive display device 10 uniformly emits light. Thus, the vending machine looking nice where the light source 13 is not seen from the external is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product display room of a vending machine having a display device.

2. Description of the Related Art An example of a conventional product display room of a vending machine will be described below with reference to the drawings. In FIG. 3, 1 is the main body of the vending machine, and 2 is a door located at the front of the main body 1. 3 is a product display room installed in the above-mentioned s2, and 4 is a lighting lamp installed in the product display room 3.

6 is a product selection device, and 6 is a product number outlet.

In FIG. 4, 7 is a protection plate formed of a see-through member;
Reference numeral 8 denotes a display device made of a material such as metal or glass and provided with a display print on its surface.

Reference numeral 9 denotes a holding device for fixing the display device 8 to the field 2.

The operation of the product display room of the vending machine configured as described above will be explained below.

When the surroundings become dark, such as at night, the lighting lights in the product display room are turned on to illuminate the display device. Therefore, when purchasing a product, etc., the illuminated display device can be seen through the protection plate formed of the see-through member.

Problems to be Solved by the Invention However, with the above configuration, at night, etc.
The light from the illumination lights located at the top and bottom of the display device has an uneven brightness distribution on the display device, resulting in poor appearance, and furthermore, the illumination lights can be seen from the outside through a protective plate made of a see-through member. was.

In view of the above-mentioned problems, the present invention provides a good-looking product display room for a vending machine in which the brightness distribution of the display device is made uniform at night, etc., and the illumination light is not visible from the outside through the protective plate. .

Means for Solving the Problems In order to solve the above problems, the product display room of the vending machine of the present invention has a built-in light source, the inner surface is a reflective surface, and the distance from the light source between the light source and the exposed surface is reduced. A thin exposure device equipped with a diffuse transmission member having a dot-like or thin line-shaped reflector so that the density is increased according to the density of the thin exposure device, and a translucent device having a display printing layer on the outside of the exposure surface of the thin exposure device. It is equipped with a display device.

Operation According to the present invention, the brightness of the exposure surface of the thin exposure device is made uniform by the above-described configuration, so that the light-transmitting display device emits light uniformly over the entire surface. Furthermore, the light source cannot be seen from the outside, which improves the display effect especially at night and contributes to increasing customers' desire to purchase. Also, it becomes possible to create a vending machine with a good appearance.

EXAMPLE Below, a product display room of a vending machine according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. It should be noted that the same components as those in the prior art will be given the same numbers and detailed explanations thereof will be omitted.

In the figure, 1Q is a display device, which is transparent and has a display print layer, and 11 is a reflector 11 made of magnesium oxide, titanium oxide, or the like.

Reference numeral 12 denotes a diffuse transmitting member in which the reflector 11 is coated on the light source side in the form of halftone dots or fine lines so that the density increases as the distance from the light source decreases. 13 is a light source, and 14 is a holding device that fixes the display device 10, the diffuse transmission member 12, and the illumination lamp 13. 15 is a thin exposure device, which is composed of the display device 10, the diffuse transmission member 12, the illumination lamp 13, and the holding device 14;
The inner surface is a reflective surface.

The operation of the product display room of the vending machine configured as described above will be described below.

The light emitted from the light source 13 is reflected by the reflector 11 coated on the diffuse transmission member 12 . The degree of reflection increases near the light source 13 where the density of the reflector 11 is high. The light reflected by the reflector 11 is reflected again by the inner surface of the thin exposure device 15 and reaches the diffuse transmission member 12. Therefore, the diffuse transmission member 1
The luminous flux reaching 2 is uniform and the display device 1o is transparent.
Since the light flux passing through the display device 1o is also uniform, the surface brightness of the display device 1o is uniform. Therefore, the limited space of the product exhibition room has a stylish design with no visible light source from the outside.

Effects of the Invention As described above, there is provided a thin exposure device that includes a built-in light source, has a reflective surface on its inner surface, and is provided with a diffuse transmission member having a dot-like or thin line-like reflector so as to increase the distance between the light source and the exposure surface. By providing the device and a light-transmitting display device, it is possible to realize a vending machine with a good-looking design without visible light sources and an even brightness distribution even in a product exhibition room with limited space.

Moreover, it has the following effects.

(1) Because it looks good, it has an outstanding ability to attract customers and at the same time can arouse the desire to purchase.

(2) By replacing the translucent display device, a design that matches the surrounding environment can be provided.

(3) Since the appearance is good, it is possible to provide a vending machine with amenities that match the surrounding environment.
