The motor 3 is mounted vertically above the center of the 10-yen coin ejection mechanism and the 100-yen coin ejection mechanism. The motor 4 is provided with a crank 4 for causing the hook-shaped cams 7a and 7b to function about the rotation axis of the motor 3 as a center of rotation. still,
As the motor 3, a reversible motor that can easily switch between normal rotation and reverse rotation is used.

Next, the operation of the coin processing apparatus according to the embodiment of the present invention will be described with reference to FIG.

The coins inserted by the user are sorted by a coin discriminating section and stored in storage tubes 1a and 1b (see FIG. 2) for each denomination. At this time, the crank 4 is at the position shown in FIG. Hereinafter, this position is called a home position. The home position is a reference position for the rotation of the crank 4.

When discharging a 100-yen coin as change, the motor rotates counterclockwise, and the crank 4 rotates in the L direction in the figure as shown in FIG. First, the crank 4 is hooked cam
It comes into contact with the arm 71a of 7a and rotates against the urging force of the cam urging spring 9a. At this time, the hook-shaped cam 7a rotates in conjunction with the rotation of the crank 4. When the crank 4 rotates further, the hook-shaped cam 7a comes into contact with and separates from the hook-shaped cam 7a, and the hook-shaped cam 7a returns to the initial state by the urging force of the cam urging spring 9a. Therefore, the pushing plate 2a does not operate depending on the rotation of the crank 4 in the L direction, and a 10-yen coin is not discharged. Subsequently, when the crank 4 rotates, the crank 4 is moved to the arm of the hook-like cam 7b as shown in FIG.
Contact 71b. At this time, the arm 72b of the hook-shaped cam 7b is
The push-out plate 2b is pushed in the direction of the storage cylinder 1b (see FIG. 2) against the urging force of the push-out plate return spring 5b. For this reason, the push-out plate 2b discharges one 100-yen coin stored in the storage cylinder 1b.

When the crank 4 rotates continuously, the arm 71b of the hook-like cam 7b
Are pushed and released, and the pushing plate 2b returns to the original position by the urging force of the pushing return spring 5b. When the crank 4 makes one rotation, it stops at the home position.

In order to discharge a plurality of 100-yen coins as change, the crank 4 may be continuously rotated in the L direction.

When a 10-yen coin is to be discharged as change, the motor 3 may be rotated in the R direction as shown in FIG. 4, as in the case of discharging the 100-yen coin. Therefore, a case where a 10-yen coin is discharged as change will be briefly described.

When the motor 3 is rotated, it comes into contact with the hook-shaped cam 7b. When the hook-shaped cam 7b comes into contact with the hook-shaped cam 7b, the hook-shaped cam 7b rotates as shown in (c), but the pushing plate 2b does not operate. Therefore,
No 100 yen coin will be released. Subsequently, the crank 4 comes into contact with and separates from the hook-shaped cam 7b and comes into contact with the hook-shaped cam 7a. The hook-shaped cam 7a operates by the rotation of the crank 4, and the pushing plate 2a is pushed out toward the storage cylinder 1a. Therefore, 10 yen coin is a storage cylinder
Released from 1a. When the crank 4 further rotates, the crank 4 comes into contact with and separates from the hook-shaped cam 7a, and the pushing plate 2a returns to the original position by the urging force of the pushing plate return spring 5a. When the crank 4 makes one rotation, it stops at the home position.

In order to discharge a plurality of 10-yen coins as change, the crank 4 may be continuously rotated in the R direction.

To summarize the above operation, when the rotation of the motor is rotated in the L direction (counterclockwise), a 100-yen coin is ejected and R
When rotated in the clockwise direction, a 10-yen coin is ejected. Further, the number of coins to be discharged is one per rotation of the crank.

In this embodiment, the rotation speed is detected by attaching a detection plate (not shown) to the motor 3 or the crank 4.
It is detected by an optical sensor (not shown) that detects each rotation.

(Effect of the Invention) According to the coin processing apparatus of the present invention, coins of two denominations can be discharged by a single motor, and the rotation direction and the number of rotations of the single motor can be controlled. Thus, a desired change can be released, so that simple control is sufficient. In addition, the coin processing device of the present invention can be controlled by a simple control circuit, can be reduced in size with a simple configuration, and consumes less power.
