Next, the operation of this embodiment will be described.

In the standby state, as shown in FIG.
As a result, the lever 34 swings rightward, the pressing member 28 is retracted rightward via the lever 34, and the coin insertion slot 14 is opened.

When a plurality of coins C are to be inserted at a time, the plurality of coins C are aligned in the left-right direction in a standing posture, and the coins C in the standing alignment state are shifted from the left-right direction to the coin input person. While being held by a finger, the coin C is inserted into the coin insertion slot 14 through the insertion recess 13 from the radial direction. At this time, the coins C may be the same denomination or different denominations.

By inserting the coin C into the coin insertion slot 14, the detection light of the coin presence / absence detection sensor 45 is blocked, and the presence of a coin is detected.

Upon detection of the presence of the coin, as shown in FIG. 2, the motor 40 is operated to rotate the cam 36 in the counterclockwise direction in FIG. Is released from the right.
The pressing member 28, which has been retracted in the above, is moved to the left by the urging of the spring 32, the left end surface of the pressing member 28 abuts on the coin C, and the urging force of the spring 32 presses the pressing member 28 and the fixed reference wall 17.
And the coin C is pinched. In a state where the coin C is held in this manner, the coin C is securely held in the standing and aligned state even when the finger is released from the coin C. Then, after the coin C is nipped, the leftward movement of the pressing member 28 stops, so that only the lever 34 is continuously moved leftward while the lever 34 is in contact with the rotary shaft 41. The movement of the lever 34 also stops.

Further, when the cam 36 rotates substantially half a turn, as shown in FIG. 3, the cam plate 38 of the cam 36 pushes the operating plate 43 to turn on the roller drive command switch 42, and the motor 40 is stopped. And the motor 25 is operated. The operation of the motor 25 rotates the roller 21 in a counterclockwise direction, so that one coin C abutting on the peripheral surface of the roller 21 is fed into the slit 19 on the back side, and the remaining coins C are on the back of the coin insertion slot 14. Movement is restricted by the wall. 1 sent to slit 19
At the moment when one coin C comes out of the aligned portion in the coin insertion slot 14 and there is a gap for one coin, the pressing member 28 is pressed by the biasing force of the spring 32.
The coins C in the aligned state move in the direction of the fixed reference wall portion 17 via, and the next fed coin C comes into contact with the roller 21 and is fed into the slit 19 in the same manner as the first coin C. Note that the feed speed of coins from the coin lump input device 2 to the identification and counting unit is set in accordance with the speed at which the identification and counting process in the identification and counting unit is enabled one by one.

In this way, the coins C are sequentially fed one by one into the slit 19, and the coins C fed into the slit 19 are guided to the coin identification and counting section through the chute 44.

If no coin is fed into the coin identification and counting section for a predetermined time after all the coins C have been sent in, an end signal is output from the coin identification and counting section which has determined that coin insertion has been completed,
Based on this end signal, the motor 25 is stopped and the motor 40 is operated again. The cam 36 is rotated by the operation of the motor 40, and the pin 39 of the cam 36 comes into contact with the lever 34 again, and the pressing member 28 is retracted rightward via the lever 34.

When the fixed position detection switch (not shown) detects that the cam 36 has rotated once and returned to the home position, the motor 40 is stopped, and as shown in FIG. To return to the standby state.

As described above, the coins C in the standing and aligned state can be inserted into the coin insertion slot 14 from the radial direction while being held by the coin inserter's finger from the left and right directions. Since the aligned state can be maintained between the roller 21 and the pressing member 28, the coin C can be easily inserted, and the aligned state of the coin C can be reliably maintained. Moreover, since the coins C are fed under the pressing condition between the roller 21 and the pressing member 28, the coins C can be fed one by one without disturbing the alignment state of the coins C.

The retraction drive means 40 is not limited to a motor, but may be an electric drive means such as a solenoid.
