Description

[Detailed description of the invention] This invention relates to a flapper opening/closing mechanism provided in a coin processing device such as a public telephone, and in particular, a main first flapper provided in a coin passage of the coin processing device and other parts of the coin passage. The present invention relates to an engagement mechanism that opens and closes a second flapper provided as an auxiliary to the first flapper.

In public telephones that process coins, the coins inserted by the customer are guided into the coin passage, and sent to a coin sorting passage provided in the coin processing unit, where the coins are checked for size, bending, etc. It detects the material, etc., and operates each part within the phone based on the detection results.

However, in such public telephones, if a bent coin or the like is inserted, a coin jam occurs in the coin passage, making it impossible to process the coins. Therefore, in such coin processing devices (for example, public telephones), a flapper opening/closing mechanism for opening the coin passage and ejecting stuck coins has become indispensable. However, in the conventional flapper opening/closing mechanism that opens and closes the main first flapper and the auxiliary second flapper, for example, when the first flapper is opened/closed, the opening/closing stroke of the first flapper directly opens the second flapper, etc. Since I was trying to open and close it, the second
There was a problem in that the degree of opening of the flapper was limited by the opening/closing stroke of the first flapper, making it impossible to obtain a large opening/closing stroke.

Furthermore, since these first, second, etc. flappers are directly engaged with each other, when the first flapper is moved, the second flapper is forcibly driven, so the movement of the second flapper is restricted due to coin jamming, etc. When the second flapper was in a closed state, the second flapper could be damaged by this clogging, such as coins.

In view of the above points, this invention makes it possible to increase the opening degree of the second flapper even when the second flapper is opened and closed by the first flapper with a small opening/closing stroke. An object of the present invention is to provide a new flapper opening/closing mechanism configured so that the second flapper is not damaged by the driving force of the first flapper even when the movement of the second flapper is restricted due to a coin jam or the like. It is something.

In order to achieve this objective, this invention includes a flapper 18 as a second flapper that forms the wall surface on the entrance side of the coin passage of the coin processing device and rotates as necessary to open the coin passage. , a flap-shaped opening plate 17 as a first flap that forms a back wall surface of the coin passage and rotates as necessary to open the coin passage, and a flap 18 as the second flap. Shaft 4 that supports freely
A coil spring 43 is provided coaxially with the flapper 18 to bias the flapper 18 in the closing direction, and a coil spring 43 is rotatably provided integrally with the opening plate 17 as the first flapper and is in contact with one end of the coil spring 43. When the opening plate 17 is rotated in the opening direction, the urging force of the coil spring 43 on the flapper 18 in the closing direction is released and the flapper 18 is rotated.
The device is characterized in that it includes a release part that releases the.

This invention will be explained below with reference to an embodiment shown in the drawings.
