DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is connected to various machines such as a pachinko machine such as a ball lending machine, a money changing machine, a change replenishing machine, a washing machine, and a polishing machine, and is provided with coins (medals and other pseudo coins). The present invention also relates to a coin sending device used for sending out a coin.

[0002]

2. Description of the Related Art In general, this type of coin dispenser is configured to scrape up a funnel-shaped coin storage tank, a hopper communicating with the bottom of the opening thereof, and coins that have fallen into the hopper from the tank, and to use the ball lending machine or the money changing machine. However, coins may cause a bridging phenomenon in their tanks, preventing them from falling into the hopper.

[0003]

Therefore, in the prior art, a large number of small holes are distributed on the wall surface of the above-mentioned coin accommodating tank, and every time a coin bridging phenomenon occurs, an appropriate rod is inserted from the small hole. Therefore, coins are agitated artificially.However, it is very troublesome for the operation, and it is not clear when the bridge phenomenon occurs. Can not.

In this respect, for example, a hexagonal column-shaped rotating drum (27) as shown in FIGS. 6 to 8 of JP-A-6-68346.
It is also conceivable to employ a coin (M) drop amount variation mechanism (18) composed of a rocking plate (28), which is elastically deformed of rubber or the like, and a closing plate (29). In order to prevent the bridging phenomenon, the rotating drum (27) must be driven to rotate by the electric motor (30) from time to time, so that its electric consumption and noise are increased unnecessarily, and the elastic rocking plate ( 28) and the closing plate (29) are damaged early, and there is a problem that their durability is inferior.

[0005]

SUMMARY OF THE INVENTION The present invention is intended to improve such a problem. For this purpose, a funnel-shaped coin storage tank, a gutter type hopper connected to the bottom of the opening thereof, and the above-mentioned hopper are provided. In a coin feeder equipped with a motor for rotating and driving a disc rotor for scraping out coins falling from a tank into a hopper, a coin stirring body and a rotation driving motor for the coin stirring body are supported at an intermediate height position in the tank, and An upper limit detection sensor and a lower limit detection sensor for the amount of stored coins are attached to the inner wall surface of the tank, and when one or both of them detects a bridge phenomenon of coins in the tank, the drive motor receiving the output electric signal. According to the first feature, it is determined that the coin stirring body is rotated,

Also provided is a funnel-shaped coin storage tank, a gutter-type hopper connected to the bottom of the opening thereof, and a motor for rotating and driving a disc rotor for scraping out coins falling from the tank into the hopper. In the coin delivery device, a coin agitator and its rotation drive motor are supported at an intermediate height position in the tank, and a sensor for detecting the upper limit of the coin storage amount is also provided on the inner wall surface of the tank, and the coin is stored on the inner wall surface of the hopper. The lower limit detection sensor of the amount is attached, and when one or both of them detects the bridge phenomenon of the coin in the tank, the drive motor receiving the output electric signal rotates the coin stirring body. This is the second feature.

A coin delivery device characterized in that: 3. A coin detection sensor (35) is made to face a bottom surface in the hopper (33) or a coin delivery path (P1) (P2) from the hopper (33). When the presence of (C) is not detected,
Rotation drive motor (28) of disc rotor (31) for scraping out coins after elapse of a predetermined time set in advance
The coin delivery device according to claim 1 or 2, wherein the setting is made to stop.
