(Prior Art) Japanese Patent Publication No. Sho 62
Some are disclosed in Japanese Patent Publication No. 45585. This coin sending device will be described with reference to FIG. This coin feeding device is provided with a coin feeding disc 3 which is rotated in the hopper 1 about an axis of rotation in a state of being inclined with respect to the horizontal, and the coin feeding disc 3 has a central circular platform at its center. Part 4 is provided. The outer peripheral portion 3a of the coin feeding disc 3 is provided with coin feeding pieces 5 protruding from the surface of the coin feeding disc 3 at positions spaced apart from each other in the circumferential direction. Coin feeding piece 5
Is for picking up coins located in the lower part of the hopper 1 as the coin feeding disc 3 rotates and lifting the coins upward. A height dimension smaller than the thickness of one coin is used for coin feeding circles. It has for the surface of the plate 3.

The coins thus lifted are eventually guided by the central circular base portion 4 and the coin delivery guide 7, and the coin outlet 6
Sent through. The coin delivery guide 7 crosses the outer peripheral portion 3a at a position of the coin delivery disc 3 at about 10 o'clock,
Then, the tip is provided so as to be in contact with the central circular base portion 4. On the lower side of the coin delivery guide 7, that is, on the side facing the coin delivery disc 3, there is provided a passage 7a for passing the coin delivery piece 5 when the coin delivery disc 3 rotates. The passage 7a is set to the minimum necessary dimension that allows the coin feeding piece 5 to pass therethrough, and by such a configuration, the thickness dimension of the coin delivery guide 7 is larger than the thickness of one coin. It is designed so that it will not happen. The width of the coin outlet 6 is set to be slightly larger than the thickness of one coin and smaller than that of two coins so that only one coin can pass through. As described above, the coin feed piece 5, the coin delivery guide 7 and the coin outlet 6 are configured such that the thickness dimension thereof corresponds to the thickness dimension of one coin, so that a plurality of coins overlap each other. The coin is not guided to the coin outlet 6 in a closed state.
