Cylindrical coin accommodating parts for accommodating various coins such as yen and 1 yen are arranged on the board at a predetermined interval, and a solenoid is disposed close to the bottom of each coin accommodating part. By driving the coin accommodating section, the coin located at the lowest position of the coin accommodating section is pushed out from the gap provided between the coin accommodating section and the substrate. In such a configuration, a predetermined amount of change can be dispensed by driving the solenoid corresponding to each coin a necessary number of times according to the change calculation result.

[Problem that the invention seeks to solve]

However, since the conventional coin ejecting device is provided with a solenoid corresponding to each coin accommodating portion, there is a drawback that the number of solenoids increases and it cannot be constructed at low cost.

The present invention has been made in view of the above circumstances, and there is no need to provide a solenoid corresponding to each coin storage section, the structure can be simplified and downsized, and costs can be reduced. To provide a coin ejecting device that can ensure reliable ejecting operation by guiding the coins reliably.

When the arm lever comes in front of the coin storage cylinder containing the coins to be stored, the arm lever vertical movement mechanism is operated to raise the arm lever to the coin pushing height, and after the arm rod passes through the coin storage cylinder, the arm lever is moved up and down. The coin ejecting control means reversely operates the lever vertical movement mechanism to lower the arm lever.

[Effect]

A timing signal is generated as the arm lever rotates with respect to the coin storage section arranged on the circumference line, and the rotational position of the arm lever is detected based on this timing signal, and the arm lever is moved to the desired position. When the coin is in a position corresponding to the coin storage part where the coin is stored,
The arm lever is controlled to move up and down, and a desired coin is ejected.

The rotating shaft 2 is constantly being rotated by the rotation of the holding member 16 and the arm lever 19 are rotating integrally with the rotating shaft 2 below the base plate 1 when coins are not being ejected. When ejecting a coin, the arm lever 19 is located in the space between the coin receiving parts ₁₁₁ to ₁₁₅ immediately before reaching the predetermined coin storage parts ₈₁ to ₈₅ containing the coins to be ejected. When the solenoid 20 is activated, the plunger rod 21 of the solenoid 20 pushes up the holding member 16 and moves the arm lever 19 above the substrate 1. At the same time, the arm lever 19 continues to rotate, and its tip 19a passes between the ejection opening of the predetermined coin storage section 8 ₁ - 8 ₅ and the coin receiving section 11 ₁ - 11 ₅ , and the arm rod 19 continues to rotate.

If a signal for a 100 yen coin is being sent from
₁ ) When the position signal is input from the arm lever position determination circuit 32, the solenoid 20 is excited and driven to raise the arm lever 19 to the coin pushing height, and the tip portion 19a of the arm lever 19 is When the coin passes through the coin storage section and a position signal thereof is input from the arm lever position determination circuit 32, the excitation of the solenoid 20 is stopped, the arm lever 19 is lowered by the spring force of the return spring 18, and the arm lever 19 is simultaneously ejected. Sends a 100 yen coin ejection completion signal to the coin designation unit 36 and returns the 100 yen coin held in the register of the ejection coin designation unit 36.
It is designed to subtract 1 from the number of yen coins. This is the same when other types of coins are ejected, and this coin ejection operation is performed by the ejected coin designating section 3.
This process is repeated until the number of coins held in the register No. 6 becomes zero.

In addition, according to such a coin ejecting operation, the coins 28 moved from the coin receiving parts 11 ₁ to 11 ₅ by the arm lever 19 are transferred to the coin ejecting port 1 in the outward direction in the circumferential direction.
Since it is moved towards 2 ₁ to 12 ₅ , the coin 28
The coins on the other coin receiving parts 11 ₁ to 11 ₅ will not be dropped, and the rotation of the arm lever 19 will not be inhibited.

Note that the board and the guide plate may be integrated, or the guide plate may not be provided and a case or the like may be used to prevent the coins from flying out in a direction other than the ejection port. The shape of the arm rod is not limited to a circular arc shape, but may be any shape that allows the coin to move outward in the circumferential direction. The type of coin may be one other than Japan, or it may be non-circular.
The configuration in which the arm rod is provided so as to be movable up and down with respect to the rotation axis may be other than the spline configuration of the embodiment.
Further, the driving means for moving the arm lever up and down may be other than a solenoid. This coin ejecting device can be widely applied to cash registers and the like.
