Next, a coin processing operation in the coin processing apparatus having such a configuration will be described. In FIG. 3, when the coin 10 is inserted from the coin insertion slot of the coin insertion slot gauge 31,
The coin 10 rolls on the coin sorting orbit 34 and the material sorting means 3
When the material of the coin 10 is selected by 5 and it is determined that the coin 10 is a pseudo coin, in FIG. 8, the two rotary solenoids 38 and 39 in the coin distribution means 29 do not operate. Therefore, as shown in FIG. 4, the pseudo coin 10 is moved to the first coin return orbit 50 in the coin return space 7.
Is returned to the coin return port from the coin return passage 53. Thus, by providing the first coin return orbit 50 for returning the pseudo coins in the coin return space 7 between the first coin storage space 8 and the second coin storage space 9,
There is no need to provide the first coin return orbit 50 above the first and second coin storage spaces 8,9. Therefore, the coin processing device 1 can be reduced in size without increasing the vertical dimension.

When the coin 10 is determined to be a legitimate coin by the material sorting means 35, one of the rotary solenoids 38 is actuated in FIG. 8 and the sorting lever 40 is turned clockwise in FIG. As the coin 10 moves, the coin 10 is distributed to the first coin storage space 8. Therefore,
As shown in FIG. 3, the coin 10 is guided to the coin storage orbit 60, and rolling is prevented by the rolling prevention portion 64 a of the guide lever 64 on the most upstream side in the coin rolling direction of the coin storage orbit 60. The guide lever 64 is dropped in the coin receiving portion 64b, rotates counterclockwise in the drawing against the weight of the weight 65, and is accumulated in the coin accumulation chamber 67.

Thereafter, when the regular coins 10 are inserted from the coin insertion slot, the regular coins 10 are sequentially accumulated in the coin accumulation chamber 67 of the coin accumulation section 61, and the four coin accumulation chambers 6 in the first coin accumulation space 8 are arranged.
When the coins are accumulated in all of 7, one rotary solenoid 38 is deactivated in FIG. 8 and the other rotary solenoid 39 is activated. Therefore, the fifth and subsequent regular coins 10 are transferred to the second coin by the coin sorting means 29.
In FIG. 5, the coin is guided to the coin storage space 9 side.
The coins are sequentially accumulated in the coin accumulation chamber 67 of the second coin accumulation space 9.

As described above, the coins 10 are stored in the first coin storage space 8 and the second coin storage space 8 at different positions in the thickness direction of the coins 10.
Since the coins are stored in the coin storage space 9, the surface area of the device does not increase.
The size of the device can be reduced. In addition, after the coins are accumulated in all the four coin accumulation chambers 67 in the first coin accumulation space 8, the coins are accumulated in the coin accumulation chamber 67 in the second coin accumulation space 9, whereby the sorting is performed. Since the operation of the coin sorting levers 40 and 41 of the means 29 is simplified, malfunction is prevented.

The coins 10 stored in the coin storage chamber 67 are:
When the denomination to be stored is determined by a control device (not shown) in accordance with the call charge, as shown in FIG.
8 coil 72 is energized. At this time, the polarity of the extending portion 71a of the iron core 71 can be selected to be N-pole or S-pole by selecting the direction of energization. Therefore, when one of the coin storage levers 66A is operated, the extension is required. Part 71
Let a be the S pole. Since the permanent magnet 69B of the other coin storage lever 66B attracts each other to the magnetic pole S pole formed in the extension 71a, the coin storage lever 66B does not operate.

One of the coin storage levers 66A is connected to the extension 7
Since the magnetic pole S pole formed in 1a and the S pole of the permanent magnet 69A repel each other, the bent portion 66a operates so as to be retracted from the coin storage portion 61 as shown in FIG. Therefore, in FIG. 3, the coin 10 in the coin storage chamber 67 falls to the coin storage track 62 and the coin storage track 6
After rolling 2, the coin 2 is guided to the coin storage passage 75. As described above, the pair of storage levers 66 are formed by one electromagnet 68.
Since A and 66B can be selectively operated, the size of the device can be reduced, the cost of the device can be reduced, and the control operation can be simplified.

When returning the coin 10 in the coin storage room 67 after the end of the call, the power supply to the electromagnet 68 is performed in the forward and reverse directions, respectively, and all the coins in the coin storage room 67 are stored in the coin storage orbit. The coin storage track 62 is rolled. By operating the rotary solenoid 85 and retracting the return blocking piece 82 of the coin storage / return lever 80 from the first and second storage spaces 8 and 9, the coin return path via the second coin return track 58. Lead to 53.

Here, when a coin jam occurs in the first coin storage space 8, in FIG. 1, the elastic engaging piece 18 engaging with the notch 21 of the first coin storage substrate 4 is used.
Is disengaged. As shown in FIG. 7, the bent portion 19 of the support piece 19 of the coin return board 3 on which the support shaft 22 is pivotally supported.

By opening, the jammed coins can be removed. Even when a coin jam occurs in the second coin storage space 9, similarly, as shown in FIG. 7, the second coin storage substrate 5 is turned around the bent portion 15 a of the support piece 15 of the substrate 2. By rotating as a moving center and opening the second coin storage space 9, a jammed coin can be removed.

When the second coin storage space 9 becomes unnecessary, as shown in FIG. 2, the elastic engagement piece 16 engaged with the notch 23 of the second coin storage substrate 5 is used. By releasing the engagement and releasing the support of the support shaft 24 pivotally supported by the bent portion 15a of the support piece 15 of the substrate 2, the second coin storage substrate 5 can be removed from the substrate 2.
