Abstract

A coin hopper includes a rotating disc having recesses that receive and hold coins one by one; a moving body that is disposed at a position corresponding to the recess and moves reciprocally between a holding position and a push-out position; a cam groove including a first route having a substantially circular shape and a second route connected to the first route at first and second branch points and protruding toward the outer periphery of the rotating disc with respect to the first route; and a cam follower disposed in the cam groove provided on a back side of the moving body. The moving body is held at the holding position when the cam follower moves along the first route and moves reciprocally between the holding position and the push-out position when the cam follower moves along the second route.

First claim

What is claimed is:

1. A coin hopper that separates coins in bulk one by one and delivers the coins individually comprising:
a rotating disc that is selectively rotatable in a first rotating direction and a second rotating direction, which is in a direction opposite to the first rotating direction;
a recess that is formed on a surface of the rotating disc, and extends from a central portion of the rotating disc toward an outer periphery of the rotating disc, opens at an outer peripheral end of the rotating disc, to receive and hold one of the coins;
a moving body that is disposed at a position corresponding to the recess, the moving body moving reciprocally between a coin holding position, which corresponds to a central portion of the rotating disc, the moving body forming a side portion of the recess and receives the coin in cooperation with the recess and the moving body can be moved to a coin push-out position, which corresponds to a position moved toward the outer periphery of the rotating disc, for pushing out the coin held in the recess toward the outer periphery of the rotating disc;
a cam wheel disposed on a back side of the rotating disc and provided with a cam groove having a predetermined shape on the rotating disc side; and
a cam follower disposed in the cam groove provided on a back side of the moving body, wherein
the cam groove includes a first route having a substantially circular shape and a second route connected to the first route at first and second branch points and protruding toward the outer periphery of the rotating disc with respect to the first route;
the moving body is held at the coin holding position when the cam follower moves along the first route and moves reciprocally between the coin holding position and the coin push-out position when the cam follower moves along the second route; and
a route switching device is provided at the first branch point, and causes a moving route of the cam follower to be switched from the first route to the second route when the rotating disc rotates in the first rotating direction and the moving route of the cam follower to be maintained in the first route when the rotating disc rotates in the second rotating direction.

2. The coin hopper according to claim 1 , wherein
the route switching device includes a rotating shaft extending perpendicularly to a bottom surface of the cam groove and a valve element disposed rotatably about the rotating shaft,
the valve element is switchable between a first position for blocking the first route and communicating the first route with the second route and a second position for blocking the communication between the first route and the second route and opening the first route, and
the valve element is pushed from the first position toward the second position by the cam follower when the rotating disc rotates in the second rotating direction.

3. The coin hopper according to claim 2 , wherein the valve element turns from the second position toward the first position under its own weight.

4. The coin hopper according to claim 2 , wherein the valve element is urged by an urging member from the second position toward the first position.

5. The coin hopper according to claim 1 , wherein
the route switching device is elastically advanceable and retractable with respect to the first route and includes an inclined surface having a predetermined angle with respect to a bottom surface of the first route and inclined toward a downstream side of the first rotating direction, and
the route switching device is retracted from the first route by being pushed on the inclined surface by the cam follower when the rotating disc rotates in the second rotating direction.
