Description

[Detailed Description of the Invention] This invention relates to a coin passage structure in a coin timer or a coin mechanism of a vending machine.

For example, a coin mechanism in a coin timer operates a switch actuating member using a coin inserted into a coin slot to set a timer. In this case, the coins inserted into the coin slot fall down the coin passage and actuate the switch actuating member. Instead of a coin, it is also possible to insert a rod-like member such as a wire into the coin passage and operate the switch actuating member. Conventionally, therefore, the coin passage is curved to prevent unauthorized use of the device.

In FIG. 1, a coin C inserted into a coin slot 1 falls down a coin passage 2 and pushes a switch actuating member 3. The coin passage 2 includes a straight passage 2A connected to the slot 1, a first curved passage 2B curved in a direction that intersects this passage 2A, and a second curved passage 2B curved in the opposite direction to this passage 2B. It is connected to passage 2C. The switch actuating member 3 is an actuator that turns on a motor (not shown), and is pivotally connected to a substrate of a coin mechanism (not shown). For example, if a wire is inserted into the coin passage 2 which is curved as shown in the figure, if it is straight, the first
It collides with the guide wall 2b of the curved portion 2B, and the tip thereof cannot reach the position where the switch actuating member 3 is pushed. However, wire
When curved like Wa and Wb, the tip Wc can be engaged with the switch actuating member 3, and the device equipped with the coin mechanism can be used illegally. As a means to prevent unauthorized use, it is conceivable to make the coin path longer and form another curved part so that even if the wire is bent, the tip cannot reach the switch actuating member. However, in order to reduce the bulk of the coin mechanism, the coin passage must be shortened. Conventional unauthorized use prevention devices have the disadvantage that a mechanism separate from the coin mechanism body must be added to the coin mechanism body, making the actual structure of the coin mechanism complicated and bulky.

The object of the present invention is to provide a coin passage structure that can prevent unauthorized use of a coin mechanism without providing a special unauthorized use prevention device.

The present invention is characterized in that a recessed portion having a size that does not adversely affect the falling of the coin is formed in the guide wall of the coin passage that guides the peripheral edge of the coin.

According to the present invention, even if a rod-shaped member such as a wire is inserted through the coin slot, the tip thereof will engage the recess in the guide wall, making it impossible for the tip to reach the switch operating member. , there is an effect. Furthermore, since the present invention only requires forming a recess in the coin passage, the appearance of the coin mechanism does not change, and it is possible to provide a coin mechanism that can prevent unauthorized use at an extremely low cost.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In FIG. 2, a plurality of recesses 4 are formed in the guide wall 2b of the first curved passage 2B. This guide wall 2b is a part that guides the periphery of a coin inserted from the coin insertion slot 1. The width and depth of the recess 4 are set to such an extent that they do not have an adverse effect such as blocking the progress of coins falling down the coin passage. The recess 4 is provided in the thickness direction of the coin, which is perpendicular to the paper surface in the figure. In the illustrated example, a plurality of recesses 4 are formed over almost the entire area of the guide wall 2b on the outside of the first curved passage 2B, but the recesses are formed in the guide wall 2bb located downstream in the coin falling direction. may be placed. Furthermore, the guide wall 2a of the straight passage 2A and the guide wall 2c of the second curved passage 2C
Of course, a concave portion may also be formed therein.

When rod-like members X ₁ , X ₂ , and X ₃ such as wires are inserted into the coin passage configured as described above from the coin slot 1, their tips are formed on the guide wall 2b of the second curved passage 2B. It engages with the recessed part 4,
It is not possible to insert any more. Even if you are lucky enough to avoid one recess 4, you will be caught in the next recess, making it extremely difficult for the tip of the rod-shaped member to reach the switch actuating member 3.

The recess 4 may have a wide width, as shown by reference numeral 4A in FIG. Further, the recessed portion as used in the present invention includes the hole 4B (see FIG. 4) that penetrates the guide wall 2b. In FIGS. 3 and 4, symbol C indicates a coin.
