A pair of left and right foreign matter removing rollers 15 and 16
And the gears G attached to these rollers 15 and 16
1 and G2 are engaged with each other, and the rollers 15 and 16 are rotated inward so as to face each other, so that foreign substances and dust other than coins inserted therein are discharged below the rollers.

A pair of left and right guide plates 17, which set the coin passage width from the start end to the end of the passage 12,
A bottom plate 19 is arranged on the bottom of the passageway following the foreign matter removing rollers 15 and 16 on the starting end side, and a coin unloading mechanism 20 is arranged on both sides together with the guide plates 17 and 18. ,
The inserted coins are aligned in the course of transportation in the coin receiving passage 12, and coins A are aligned and fed one by one from the outlet of the coin receiving passage 12 to the checker 21 at the back of the apparatus.

The above-described coin one sheet take-out mechanism 20 includes a pulley 2

, A reverse roller 29 provided coaxially with the pulley 25, and a feeding roller 31 provided opposite the pulley 23 via the normal rotation belt 24. Driven roller 3 on the same axis as 22 and 28
2 and 33, while the rotating shaft 34 of the transport motor M1
The drive pulley 35 is fitted to the drive pulley 35, the guide pulleys 36 and 37, and the two driven pulleys 2 described above.
A drive belt 38 is stretched between the rollers 2 and 28, and is configured to be driven to rotate in the direction of taking out one sheet.

Here, the distance between the opposing surfaces on the starting end side where the above-mentioned forward and reverse rotation belts 24 and 29 are opposed to each other is set large,
The opposing width on the terminal side between the 4,29 faces is set to a predetermined coin width suitable for taking out one sheet. Thereby, the plurality of coins A, which are overlapped by the above-described reverse rotation belt 29, are aligned, and the aligned coins A are sequentially conveyed one by one to the check section 21 by the above-described normal rotation belt 24.

At the beginning of the coin receiving passage 12, a plurality of pairs of insertion port detection sensors S1... For photoelectrically detecting the insertion of coins from outside the guide plates 17, 18 are arranged. By being shielded from light for a certain period of time, insertion of coin A into coin receiving passage 12 is detected. Further, on the inner side surface of the coin receiving passage 12 following this, a plurality of pairs of remaining coin detection sensors S2... S3 is disposed to detect the state of taking in and transferring coins, and to turn ON / OFF the transfer motor M1 based on the detection signal of the insertion slot detection sensor S1 when coins are inserted, and to turn ON / OFF the transfer motor M1. The first wall vibration mechanism 13 and the second wall vibration mechanism 14, which will be described later, are driven and stopped in conjunction with the OFF operation.

The first wall vibrating mechanism 13 vibrates one of the two guide plates 17, 18 for setting the width of the coin passage. L-shaped diaphragm 1 whose sides are separated independently
The vibrating plate 17a has substantially the same length as the foreign matter removing rollers 15 and 16 disposed on the start end side of the coin receiving passage 12, and a fulcrum pin 39 is pivotally mounted on the outer surface of the vibrating plate 17a. One end of an L-shaped piece 40 is connected, and this L-shaped piece 4
A cam-corresponding roller 41 is protruded from the other end of the pulley 27, and the cam-corresponding roller 41 is urged by a spring 43 to contact the cam 42 fixed coaxially with the pulley 27 described above. As a result, the cam 4 rotating with the driving of the transport motor M1
2 displaces the cam-corresponding roller 41, and based on this, the diaphragm 17a integral with the L-shaped piece 40 vibrates little by little in the width direction of the passage, and vibrates the coin in the initial stage of insertion.

The second wall vibrating mechanism 14 vibrates the bottom plate 19 forming the bottom surface of the coin receiving passage 12. As shown in FIGS. 3 and 4, the second wall vibrating mechanism 14 includes a vibration motor M2 and a vibration motor M2. An eccentric shaft 44 eccentrically rotated by the motor M2 and a bottom plate 19 vibrating based on the eccentric rotation action.
It is composed of

The above-described vibration motor M2 and the eccentric shaft 44 have a fixed frame 45 such that both axial directions are parallel to the passage width direction.
The driving gear G3 fixed to the main shaft of the vibration motor M2 and the driven gear G4 fixed to the eccentric shaft 44 mesh with each other to rotate the eccentric shaft 44. In this case, the eccentric shaft 44 that is rotatably supported by the fixed frame 45 has an eccentric shaft portion 44 formed by shifting the axis of the eccentric shaft by an eccentric amount C at its shaft end.
a, and the eccentric shaft portion 44a supports the bottom plate 19 vertically on the lower surface of the bottom plate 19 to support the bottom plate 19 by an amount of eccentricity C.
Only the vibration is allowed and the shaft is supported.

The bottom plate hanging piece 46 has a U-shaped groove 47 cut out along the passage direction, and a slide roller 48 protruding from the fixed frame 45 in the width direction of the passage.
Are allowed to slide and engaged, and the eccentric shaft portion 44a described above is engaged.
And the slide roller 48 support the entire bottom plate 19 to optimally set the vibration angle and the vibration amount of the bottom plate 19. As a result, when the vibration motor M2 is driven, the eccentric shaft 44 rotates accordingly, and the eccentric shaft portion 44a at the shaft end rotates eccentrically, so that the bottom plate 19 is notched up and down and in the direction of the passage. And the bottom plate 19
Vibrates the coins guided above. The rotation of the foreign matter removing rollers 15 and 16 described above is rotationally driven through a power transmission mechanism 49 that is driven to rotate by receiving the rotational force of the transport motor M1.

FIG. 5 shows a block diagram of a control circuit of the coin receiving device. The CPU 51 controls each circuit device according to a program stored in the ROM 52, and stores the control data in the RAM 53 in a readable manner.

The coin clogging detection timer T1 is connected to the coin slot 1
The remaining coin detection timer T2 measures whether or not the coins A... Inserted in 1 have been taken into the inside, and whether or not the coins A... Remain in the coin receiving passage 12.

By the way, the CPU 51 simultaneously turns on the transport motor M1 and the vibration motor M2 based on the detection signal of the insertion slot detection sensor S1, and interlocks with the operation of taking in the inserted coins, thereby causing the first wall vibrating mechanism 13 to operate. And the second wall vibration mechanism 14 are simultaneously driven. As a result, the coins are vibrated in the coin receiving passage 12, and the relative sliding phenomenon between the coins is smoothly performed, thereby promoting the rolling and aligning operation of the coins.

The processing operation of the coin receiving device thus configured will be described with reference to the flowchart of FIG.
When a plurality of coins A are inserted into the coin insertion slot 11 at once, the insertion is detected by the insertion slot detection sensors S1..., And based on the detection, the CPU 51 determines the connection between the transport motor M1 and the vibration motor M2. Both are driven to perform a loading operation, and a coin clogging detection timer T1 is started (steps n1 to n1).
n4).

At this time, the vibration plate 17a of the first wall vibrating mechanism 13 vibrates little by little in the width direction of the passage in conjunction with the drive of the transport motor M1, and vibrates inward while applying vibration to the coins at the initial insertion. Take in operation. Thereby, the plurality of coins A inserted into the coin insertion slot 11 are immediately subjected to the vibrating action of the wall surface in the coin receiving passage 12 and the separation of the coins is ensured, and the relative slip phenomenon of the overlapped coins is reduced. Make it run smoothly.

Subsequently, the plurality of coins A on the coin receiving passage 12 are taken in while being guided by the foreign matter removing rollers 15 and 16 and the left and right guide plates 17 and 18, and the coin single sheet unloading mechanism 20 is rotated. Reaching the space between the reversing belt 24 and the reversing belt 29, the plurality of coins A overlapping each other are aligned by the reversing contact action of the reversing belt 29, and the coins guided there are vibrated. The eccentric shaft portion 44a of the second wall vibrating mechanism 14 eccentrically rotates in conjunction with the driving of the motor M2, and the bottom plate 19 having received the eccentric rotation vibrates little by little in the vertical direction and the direction of the passage. The coins A that have been guided upward are vibrated to perform alignment while promoting alignment. These aligned coins A are forward rotation belts 2.
The paper is conveyed to the inside by the feed roller 4 and the feeding roller 31, and guided one by one to the check section 21.

If the coin clogging detection timer T1 times out before the coin detecting section entrance detecting sensor S3 detects and detects the passing of coins during the receiving operation of the coins A,.
It is determined that the coin is jammed (steps n5 to n6), and if the coin jam detection timer T1 times out while the coin detection unit detection sensor S3 continues to detect the coin, it is determined that the coin is jammed (steps n7 to n8). ).

When the coin detection sensor S3 stops detecting coins, the remaining coin detection timer T2 is started to confirm the completion of taking-in. In this case, if a coin is detected by the insertion slot detection sensor S1 and the remaining coin detection sensor S2, it is determined that there is a remaining coin, and the CPU 51 executes the operation for detecting a jammed coin again (steps n9 to n10).

On the other hand, if the remaining coin detection timer T2 times out without detecting the remaining coins in the coin receiving passage 12, it is determined that there is no remaining coin, and the motors M1, M2 are stopped to stop one coin. The reception is completed, and the next input is prepared (steps n11 to n14).

As described above, the coin inserted into the coin insertion slot receives both the vibrating action of the side plate facing the side and the bottom face facing the bottom face in the coin receiving passage. Separation between the coins is ensured, and the relative slip phenomenon between the overlapped coins is smoothed, so that the coins can be taken in one by one. In particular, coins inserted in a lump are received in a state in which the improper interference between coins is eliminated by vibrating action and the coins are rolled under their own weight, so that coin jamming and stagnation can be prevented.
