Abstract

The coin sorting device is equipped with a coin passage which guides coins that are inserted via a coin insertion opening, a gate plate for opening and closing the coin passage, a coin jamming detection sensor which is installed at an intermediate point in the coin passage, for detecting the jamming of coins passing through the coin passage, and a gate plate opening mechanism which is actuated by a detection signal from the detection sensor, and which automatically opens and closes the gate plate.

Claims

1. A coin sorting device comprising a coin passage for guiding coins inserted via a coin insertion opening, and a gate plate for opening and closing this coin passage, characterized by:

a coin jamming detection sensor provided at an intermediate point in the coin passage, for detecting jamming of coins passing through the coin passage; and

gate plate opening means comprising;

driving means comprising a motor which is actuated based on a detection signal of the detection sensor,

an arm member which is driven by the driving means to perform a reciprocating motion in the horizontal direction;

a projection formed on a base end portion of the arm member;

a tapered member formed on a back surface of the gate plate, for opening the gate plate by making sliding contact therewith when the arm member performs a reciprocating motion; and

a projection formed on the tapered member so as to project toward the base end portion of the arm member, for opening the gate plate even further by contacting the projection formed on the base end portion of the arm member when the arm member performs a reciprocating motion.

2. A coin sorting device according to claim 1, wherein the coin jamming detection sensor comprises:

coin discriminating means disposed at an intermediate point in the coin passage, for ascertaining genuineness of inserted coins and denominations of genuine coins; and

a controller for judging whether or not coin jamming has occurred in the coin discriminating means based on a detection signal from the coin discriminating means, and for sending an actuating signal to the gate plate opening means in cases where it is judged that coin jamming has occurred in the coin discriminating means.

3. A coin sorting device comprising a main body and a gate plate for covering the upper front portion of the main body such that the gate plate can be opened and closed, and a coin passage provided between the main body and the gate plate for guiding coins inserted via a coin insertion opening, wherein coins stuck in the coin passage are released by opening the gate plate so that the coins are caused to drop downward, characterized by:

a coin jamming detection sensor provided at an intermediate point in the coin passage, for detecting the jamming of coins passing through the coin passage;

gate plate opening means comprising;

driving means comprising a motor which is actuated based on a detection signal of the detection sensor,

an arm member which is driven by the driving means to perform a reciprocating motion in the horizontal direction;

a projection formed on a base end portion of the arm member;

a tapered member formed on a back surface of the gate plate, for opening the gate plate by making sliding contact therewith when the arm member performs a reciprocating motion; and

a projection formed on the tapered member so as to project toward the base end portion of the arm member, for opening the gate plate even further by contacting the projection formed on the base end portion of the arm member when the arm member performs a reciprocating motion; and

a step portion formed in the surface of the main body beneath the coin passage positioned directly underneath the coin insertion opening, the step portion being caused to strike at least one coin among a plurality of coins dropping downward from the coin insertion opening while overlapping in the direction of thickness.

4. A coin sorting device according to claim 3, wherein the coin jamming detection sensor comprises:

coin discriminating means disposed at an intermediate point in the coin passage, for ascertaining genuineness of inserted coins and denominations of genuine coins; and

a controller for judging whether or not coin jamming has occurred in the coin discriminating means based on a detection signal from the coin discriminating means, and for sending an actuating signal to the gate plate opening means in cases where it is judged that coin jamming has occurred in the coin discriminating means.
