Title: Coin transfer device for slot machine
Inventor: SAKATA TAKEHISA
IPC: G07D9/00
Filed: 1991-03-30
Abstract: PURPOSE:To prevent a belt from moving in a zigzag direction or running off its track and save expenses and time for repair by the arrangement such that the total length of belt conveyors is made shorter, rotational speeds thereof are increased, and they are installed in an inclined and partially overlapping relationship, wherein only a conveyor for a coin tank in need of coins can be rotated reversely. CONSTITUTION:A plurality of coin feeding conveyors (a) are inclined in such a manner that their rear edges are lowered and their forward edges are raised and the forward edges partially overlap with the rear edges and a coin receiving port 14 is located at the rear of the conveyors. If a metal empty sensor mounted on a coin tank 8 detects shortage of metal, a controller connected to the sensor feeds coins in large quantities from a hopper 23. And only a conveyor (a) for feeding coins to the coin receiving port 14 rotates reversely to send the coins to the rear part, thereby feeding a predetermined quantity of coins. Further, the length of the conveyor (a) is made short. As a result, meandering and running off of a belt 4 is prevented and quantities of repair and repair time can be saved.
