Abstract

PURPOSE:To obtain free design with unified feeling which does not divide the design of a back panel by bonding two transparent conductive films on a transparent sign panel, and providing a controller which controls the panel by means of the resistance change of the conductive part. CONSTITUTION:A transparent sign panel 5, and two transparent conductive films 15 and 16 which are bonded on the sign panel 5 and whose contact resistances are changed by suitable pressure are provided. When a mark part 16b corresponding to an indicated commodity 6 is pressured by a finger, gaps 17 are eliminated, a conductive pattern 16a makes contact with a conductive pattern 15a, the contact resistances drastically drop, the information is inputted to an input/output part 12 of a controller 11, and the prescribed commodity is delivered to a commodity output port 7 by the decision of an arithmetic part 13. Thus without dividing the design of the back panel by a switch, frame, etc., the free design can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product selection device in a vending machine for cans, bottles, etc.

Conventional technology In recent years, display effects have become important to vending machines, and their character as advertising devices has become stronger. clarification or transparency is required.

An example of the above-mentioned conventional product selection device for a vending machine will be described below with reference to the drawings.

FIG. 6, FIG. 6, and FIG. 7 show an overall view of a conventional product selection device of a vending machine, an enlarged sectional view of a main part, and a configuration of the product selection device of a vending machine.

In FIG. 6, 1 is the main body and 2 is the door.

A frame 3 is located in the center of the door 2 at a height that is easy for people to touch. 4 is a pack panel with advertising pictures etc. drawn on it. A sign panel 6 is made of a transparent resin plate and is attached to the door 2 and the frame 3.
covers the front of the

6 is an exhibited product and is attached to the back spring A/4. 7 is a product number outlet. 8 is a push button,
It is rotatably mounted on the frame a via a switch holder 9 as shown in FIG. 1o is a switch that comes into contact with the push button 8;
It is attached to the holder 9 at a position where it can be operated by the rotation of the holder 9. In FIG. 7, reference numeral 11 denotes a control device including an input/output section 12, an arithmetic section 13, and so on. The storage section 14 is composed of multiple components.

The operation of the product selection device for a vending machine configured as described above will be described below.

When purchasing a product, when the pushbutton 8 corresponding to the displayed product 6 mounted on the back panel 4 is pressed, the switch 10 is activated, and this information is input to the input/output section 12 of the control device 11, and is calculated. Based on the determination made by the section 13, a predetermined number of products are carried out to the product lower section.

Problems to be Solved by the Invention However, in the above configuration, the frame 3 is made of an iron plate or the like and is opaque, and the switch 1o is also opaque.
When the back spring/I/4 is seen from the front, it is divided into parts such as the frame 3 and the switch 10, and the back spring/L
/4 It had the problem of limiting the degree of freedom in the design of the pictures drawn on it.

In view of the above problems, the present invention provides a product selection device for a vending machine in which the design is not spoiled by frames or switches.

Means for Solving the Problems In order to solve the above problems, the product selection device for a vending machine of the present invention includes a transparent sign spring p and two springs that are adhered to the sign panel and whose contact resistance changes with moderate pressing pressure. It is composed of a transparent conductive film.

Effect of the present invention With the above-described configuration, the switch part for selecting the product is composed of two transparent conductive films, and since there is no frame for mounting the switch, the design of the back spring ρ on the back side can be seen through. , the back panel design will not be divided by frames or switches.

Embodiment Hereinafter, a product selection device for a vending machine according to an embodiment of the present invention will be described with reference to the drawings.

However, the same configuration as the conventional example is given the same number.
The explanation will be omitted. In Fig. 1, 16 is a first conductive film that is adhered to the surface of the sign spring/L/6, and is made of a transparent resin such as polyester. As shown in FIG. 2, the number of energizing patterns 115a corresponding to the positions of the displayed products 6 is formed on the surface opposite to the adhesive surface. The conductive pattern 15a is formed of a transparent conductive material such as indium oxide by sputtering or the like. Reference numeral 16b denotes a connecting portion, through which each energizing pattern 15a is connected to the input/output portion 16. 1
A second conductive film 6 is made of the same material as the first conductive film, and has the conductive pattern 16a formed on one side thereof.

16b is a landmark mark drawn at a position corresponding to the position of the displayed product 6. Reference numeral 160 denotes a connecting portion through which the current-carrying pattern 16a is connected to the input/output portion 16. As shown in FIG. 3, the second conductive film 16 has a conductive pattern 16a with a minute gap (for example, 0.1 square or less) between the conductive patterns 15a and 17 of the first conductive film 16.
It is bonded to the sign spring /L/6 so as to form or lightly contact with the sign spring /L/6.

The operation of the product selection device for a vending machine configured as described above will be explained using FIGS. 1 to 4. When the landmark mark 16b corresponding to the displayed product 6 is pressed with a finger, the gap 17 disappears and the energizing pattern 16a and the energizing pattern 15a come into contact with each other as shown in FIG. is the input/output section 1 of the control device 11
2, and according to the judgment of the calculation unit 13, a predetermined number of products are carried out to the product output lower.

As described above, according to this embodiment, a first conductive film on which a conductive pattern of the number of transparent display products is formed adhered to the surface of a transparent sign panel, the first conductive film, and a conductive part Using a transparent second conductive film that is bonded to form a slight gap or make light contact, inputting a signal of the change in contact resistance to the control unit via the input/output unit. Therefore, the design of the back spring μ of the vending machine does not need to be divided by switches, frames, etc., and can be designed freely.

Effects of the Invention As described above, the present invention has two transparent conductive films adhered to a transparent sign panel, and a control device that controls the resistance change of the conductive part is provided, thereby making it possible to avoid disrupting the design of the sign panel. It is possible to realize a vending machine with a free design that is experiential.
