2. Description of the Related Art FIGS. 6 (a), 6 (b) and 6 (c) show a sectional structure of a conventional push button switch device for a vending machine, and FIG. 6 (a) shows a state after assembly. Figures (b) and (c)
FIG. 4 is a diagram showing a state before assembly. The vending machine push button switch device 1 has a structure in which a plurality of independent switches are arranged in a line, and FIG. 1 shows one switch.
This device 1 has a case 2 having a cylindrical portion 23 inserted through a packing 11 into a panel hole 110 provided in a front panel 100 of a vending machine, and a board mounting member engaging hole 23a of the case 2. A lens provided to be able to protrude and retract with respect to the reflector 13 engaged by the inclined protrusion 131 of the cylindrical portion 130 and the plurality of button holes 20 provided in the case 2 via the in-case seal member 8 and the holding member 12 thereof. 3, LED 41a, 41b, switch circuit operating section 42
The board mounting member 1 which holds the circuit board 4 on which the circuit components such as are mounted, engages with the pair of upper and lower legs 132 and 133 of the reflector 13 and draws the case 2 toward the front panel 100.
6. The reflector 13 includes a reflector 136 having a light passage hole 136a formed therein.
2 and 133 are provided with an inclined projection 134 and a concave portion 135. The board mounting member 16 includes a back portion 160, an upper flange 161, and a lower flange 162, and has a side inclined protrusion 163 and a bottom inclined protrusion 164 formed on the back portion 160. Further, a metal reinforcing plate 17 having a U-shaped cross section and having an opening 17 a is attached to the substrate attaching member 16.

[0003] When a purchaser inserts a predetermined coin into a vending machine, an LE for display for sale mounted on the circuit board 4 is displayed.
D41a lights up. On the other hand, when the sold product is sold out, the sold-out LED 4 mounted on the circuit board 4 is displayed.
1b lights up. The lighting light of the LED 40a or 40b is emitted to the outside through the light passing portion 85 of the translucent case inner sealing member 8 and the lens 3 while being reflected on the inner surface of the light passing hole 136a of the reflector portion 136. The surface of the in-case seal member 8 has a display pattern (sellable and sold out) that transmits light at positions corresponding to the LEDs 41a and 41b. When the LED 41a for sale indication is turned on and selling is possible, when the purchaser presses the lens 3, the in-case sealing member 8 having elasticity is compressed and deformed.
The switch pressing section 85 of the seal member 8 in the case turns on the switch circuit operating section 42 on the circuit board 4 and the sold product is carried out to the sales outlet.

[0004] Such a push-button switch device 1 first comprises:
As shown in FIG. 2B, the cylindrical portion 23 of the case 2 is assembled in a state where the case 2, the lens 3, the seal member 8 in the case, the holding member 12, the reflector 13 and the packing 11 are assembled.
Is inserted into the panel hole 110 of the front panel 100, and the case 2 is temporarily fixed to the front panel 100 with tape from the front side of the front panel 100, and the metal reinforcing plate 17 and the circuit board 4 are attached as shown in FIG. By inserting the mounted substrate mounting member 16 toward the reflector 13 shown in FIG.
2, 133 are pushed and spread over the inclined projection 134, and the bottom inclined projection 164 enters the recess 135. The pair of legs 132 and 133 of the reflector 13 are
The case 2 is pulled into the front panel 100 side, and the packing 11 is compressed and deformed, and the gap between the cylindrical portion 23 of the case 2 and the panel hole 110 can be waterproofed. In addition, since the circuit board 4 has a structure in which the circuit board 4 is arranged inside the front panel 100, the size of the protrusion toward the front can be reduced.

[0005]

However, according to the conventional push-button switch device for a vending machine, when replacing the dirty case 2, the lens 3 and the like at the time of renewal of the vending machine, the substrate mounting member 16 must be connected to the reflector. However, since the bottom inclined projection 164 is engaged with the concave portion 135, it is difficult to release the engagement by using a tool such as a screwdriver. 1
When the case 2 is inserted into the case 3, the case 2 may come off from the front panel 100, and it takes time to mount the board mounting member 16. Further, since one switch has only two LEDs, one for sale indication and the other for sale indication, there is a drawback that display contents are limited.

Accordingly, it is an object of the present invention to make it possible to reduce the size of the protrusion in the forward direction and to have a superior waterproof property, while easily replacing components such as a case and a lens when renewing a vending machine. It is an object of the present invention to provide a push button switch device for a vending machine which can perform the above.
