And the payout of coins in this kind of coin payout device is
The lowest coins stacked on the bottom of the coin storage cylinder,
The coin is paid out in a substantially horizontal direction by a payout member provided with an extruding portion that projects to a thickness equal to or less than the thickness of the coin. Therefore, in such a coin dispensing device, it is necessary that coins are stacked and stored in the coin storage cylinder in the thickness direction. Therefore, conventionally, in order to obtain a stable coin payout, a predetermined number of coins are stacked and stored as coins in advance in the coin storage cylinder so that a reliable coin payout can be performed. That is, the coin storage cylinder in this type of coin processing device is generally liable to cause a coin standing in the coin storage cylinder because the inserted coins are automatically replenished.
Even if coins stand up when they are replenished on the stacked and stored coins, they can be stacked in a normal state when the lower coins are dispensed or the coins inserted next fall.

(C) Problem to be Solved by the Invention As described above, conventionally, it has been necessary to stack and store a predetermined number of coins in advance in the coin storage cylinder as sleeping money. Therefore, if the stored coins are low-value coins such as 10-yen coins, the amount of stagnation in the storage cylinder will not be large, but if they are high-value coins such as 500-yen coins, they will be large and there is a management problem. For this reason, it is best to eliminate the sage money and automatically replenish the coins that have been inserted, and use the coins as change. A coin is liable to stand on the bottom (51) in the (50), and when the payout operation by the payout member (52) is performed in this state, problems such as coins not being paid out occur.

Therefore, the present invention provides a coin payout device that can reliably pay out coins even if a coin that has been automatically replenished causes a coin standing without storing a shackle in a coin storage cylinder. Is.

(D) Means for Solving the Problem In order to solve the above problems, the present invention provides a coin dispensing device for dispensing coins from the lowest coin in a coin storage cylinder in which coins are stacked and stored in the thickness direction. Drive device driven based on the above, and a drive that is extended into the extrusion passage opened at the bottom of the coin storage cylinder and contacts the lowest coin, and is connected to the drive device and is reciprocally driven in the coin dispensing direction. A member and a drive member, which are connected to and disconnected from each other via a connecting mechanism, are located outside the coin storage cylinder at the standby position and move by the drive of the drive member to enter the coin storage cylinder. And a storage means for storing the number of coins stored in the coin storage cylinder, and a coin delivery signal which is stored in the storage means. When the number of coins is a predetermined number, the connecting member separates the driving member and the payout member to drive the driving device to reciprocate the driving member, and after this operation, the connecting mechanism operates to It is provided with a control means that connects the driving member and the payout member and causes the payout member to pay out coins.

(E) Operation When a coin payout signal is input to the control means, the control means reads out the number of coins stored in the coin storage cylinder from the storage means, and if the predetermined number is reached, the connecting mechanism causes the drive member and the payout member to operate. And the driving device is driven to reciprocate the driving member. By the reciprocating movement of the driving member, the lower end of the coin in the standing state of the coin is operated, and the coin is tilted onto the bottom of the coin storage cylinder to bring it into a normal state. At this time, if the coin is in the normal state, the coin remains in the normal state only by operating the drive member. After the reciprocating operation of the drive member, the connecting mechanism operates to connect the drive member and the payout member, and the reciprocating operation of the drive member causes the pushing portion of the payout member to pay out the lowest coin in the storage cylinder.

The operating rod (15) pushes the connecting member (11) upward through the escape groove (8C), and the connecting member (11) is connected to the connecting groove (8B).
The drive member (8) and the payout member (10) are disconnected from each other by being located above.

Here, when the coin payout signal is input to the payout control device (21), the payout control device (21) reads the number of coins stored in the coin storage cylinder (4) to be paid out from the counter (20), and the numerical value thereof is read. If the value is "1", it is determined that the number of coins stored is one, and the drive motor (5) is driven. in this case,
Since the solenoid (14) remains in the demagnetized state, the connecting member (11) is pushed up by the operating rod (15), and therefore the payout member (10) and the drive member (8) are connected. Absent. Therefore, the drive member (8) independently moves in the direction of the arrow (D) as shown in FIG. 4 by the rotation of the disc (7). By this movement of the driving member (8), for example, if the coin (C) is in the coin standing state as shown in FIG. 8, it can be brought down to the normal state as shown in FIG. Then, when the drive member (8) moves and returns to the standby state shown in FIG. 1 by the disc (7), the control switch (22) operates and sends a control switch signal to the dispensing control device (21).
When the payout control device (21) receives the control switch signal, it stops the drive motor (5) and subsequently excites the solenoid (14). As a result, the operating rod (15) is moved downward, so that the connecting member (11) projects downward due to the bias of the spring member (12) and loosely fits into the connecting groove (8B) of the drive member (8). The payout member (10) is connected to the coupling drive member (8). Then, the payout control device (21) drives the drive motor (5) again, and the drive of the drive motor (5) causes the disc (7) to rotate. Therefore, the drive member (8) moves in the direction of the arrow (D) together with the payout member (10) by the drive rod (7A) loosely fitted and engaged in the drive groove (8A), as shown in FIG. By the movement of the payout member (10), the bottom portion (4
The coin (C) on A) is the pushing part (10A) of the payout member (10).
The coin is pushed out to the coin payout passage (18) through the opening (4B). Then, when the disc (7) further rotates and the drive member (8) and the payout member (10) return to the standby position, the control switch (22) operates to output a control switch signal to the payout control device (21). Deliver to. Therefore, the payout control device (21)
Demagnetizes the solenoid (14) and stops the drive motor (5) to end the coin dispensing operation when the number of stored coins is one.

On the other hand, when the payout signal is input to the payout control device (21) and the number of coins stored in the corresponding counter (20) is two or more, the payout control device (21) causes the drive member ( 8) The solenoid (14) is operated without being driven independently, the drive member (8) and the payout member (10) are connected, and the drive member (8) reciprocates together with the payout member (10). The coin payout operation is performed.

(G) Effect of the Invention Since the present invention is configured as described above, even when a coin stands on the bottom of the coin storage cylinder, the coin can be paid out after being brought down to the normal state. Therefore, it is possible to eliminate the need for a shackle and to reliably dispense coins.
