DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin dispensing apparatus which is incorporated in a coin processing machine of a financial institution and an automatic machine such as a vending machine and an automatic currency changer, and which dispenses coins one by one.

[0002]

2. Description of the Related Art As a conventional coin feeding device, for example, a structure described in Japanese Patent Application Laid-Open No. Sho 59-68087 is known.

In this coin feeding device, a circular space, a coin delivery passage communicating with the circular space, and a guide protrusion for guiding coins to the coin delivery passage are formed on an inclined base, and a plurality of blades are provided in the circular space. A rotor having a hole, a perforated turntable having a plurality of holes for receiving coins is attached,
Further, a hopper for storing coins is attached to the base.

[0004] By rotating the perforated rotary disk and the rotor, the coins accommodated in the hopper are agitated while coins are introduced into the respective holes of the perforated rotary disk and guided to the rotor. The coins are sent out one by one from the coin feeding passage while making contact with the coins.

[0005]

In the conventional apparatus, the coins are inserted into each hole of the perforated rotating disk while rotating the perforated rotating disk and the rotor to stir the coins accommodated in the hopper. The coins are guided one by one from the coin delivery passage while being brought into contact with the guide projections by the rotor, so that the coins are always forced in the delivery direction. For this reason, coins that are somewhat clogged will be forcibly sent out, but if the coins are relatively soft, such as 1 yen coins, or if they are damaged or deformed, the coins will be further deformed by the forcing force, There is a problem that coins cannot be sent out due to being bitten.

Further, since coins are not sent out unless coins enter each hole of the perforated rotating disk, the rotation speed of the perforated rotating disk cannot be increased, and as a result, coins are fed at high speed (one second). There is a problem that it is impossible to feed out 10 or more sheets.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coin feeding device which is small in size, does not cause jamming or jamming of coins, and can feed at high speed.
