The saucer 18 has a saucer portion 28 having a substantially U-shaped cross-section facing the upper surface of the rotary disc 17, and mounting piece portions 29 projecting outwardly on both sides are formed at both ends of the saucer portion 28. ing. A slit portion 30 is formed at an edge of the saucer portion 28 facing the rotating disc 17 to allow passage of one coin that comes into surface contact with the rotating disc 17 as the rotating disc 17 rotates forward. There is.

On the upper surface of the rotary disc 17, from the slit portion 30 to the discharge port portion 31 provided in the lower region of the rotary disc 17,
A coin passage 32 is formed in which coins passing through the slit portion 30 are regulated and sent in a one-layer, one-row state. This coin passage 32 is
An interval is formed between the upper surface of the rotating disk 17 and a thickness guide plate 33 that is disposed so as to face the upper surface of the rotating disk 17, with a space for allowing one coin to pass in the thickness direction. ,
One row of coins can pass in the radial direction between the width guide plate 34 arranged along the outer circumference of the rotary disc 17 and the peripheral surface of the cam 42 (to be described later) fixed to the rotary shaft 20 and the width guide plate 35. And are formed with a space therebetween. The width guide plate 34 is arranged from a position in the vicinity of the tray 18 to one side of the discharge port portion 31.
The width guide plate 35 has a guide portion 36 arranged on the other side of the discharge port portion 31 and arranged on the rotary disc 17.

A shutter for opening and closing the slit portion 30 is provided on the back side of the slit portion 30 of the tray 18 (the side opposite to the coin storing portion 15).
37 are provided. The opening / closing means 38 for opening / closing the shutter 37 is provided with an arm 39 having the shutter 37 attached to the tip thereof, and the base portion of the arm 39 is rotatably supported by a support shaft 40. A substantially triangular protrusion 41 protruding in the direction of 17 is in contact with a cam 42 fixed to the rotary shaft 20. The cam 42 is disc-shaped, and is configured so that the shutter 37 opens with the projection 41 abutting against the end face facing upward, and the recess 43 formed on the end face corresponding to the rotation fixed position of the rotating disc 17. The projection 41 is engaged with and the shutter 37 is closed. The leaf spring 44 that contacts the arm 39 keeps the projection 41 in contact with the cam 42.

A regulating member 45 for intermittently regulating the passage of coins is arranged at a position laterally displaced from the width center of the coin passage 32 near the end of the thickness guide plate 33 of the coin passage 32. . The actuating means 46 for actuating the restricting member 45 includes an arm 48 to which the restricting member 45 is attached to the tip end via a mounting piece 47.
The base of the arm 48 is rotatably supported by the support shaft 40, and the cam roller 49 rotatably provided on the tip side of the arm 48 contacts the cam 50 fixed to the rotary shaft 20. Has been done. The cam 50 has a disk shape and is configured so that the tip end of the restriction member 45 enters the coin passage 32 and restricts the passage of coins in a state where the cam roller 49 is in contact with the end surface facing upward. When the cam roller 49 comes into contact with each of the convex portions 51 projecting at two locations on the circumference, the regulating member 45 retracts from the coin passage 32 to allow the passage of coins.
The cam spring 49 is kept in contact with the cam 50 by the leaf spring 52 that comes into contact with the arm 48.

The support shaft 40 and the leaf springs 44, 52 are supported by a holding frame 53 having a substantially U-shaped cross section.

Further, an optical sensor 54 for projecting and receiving detection light through the window hole 23 is arranged at a fixed position of rotation of the rotary disc 17. The sensor 54 detects the fixed position of rotation of the rotary disc 17 and the presence / absence of coins in the coin pool 15.

Further, a coin processing unit 61 is arranged below the coin batch inserting device 2, and the coin processing unit 61 is a coin passage.
Coins that are intermittently discharged one by one from the 32 discharge ports 31 are received through the receiving unit 62, and the coins are identified and counted.

Next, the operation of this embodiment will be described.

In the standby state, the rotating disk 17 is stopped at the fixed rotation position, the surface portion 21 having a small friction coefficient faces the lower surface area of the coin storing portion 15, and the projection 41 of the arm 39 of the opening / closing means 38 is cammed.
The slit portion 30 is closed by the shutter 37 by engaging with the concave portion 43 of 42.

When a plurality of coins are thrown in at one time, a plurality of coins are thrown into the coin pool 15 from the slot 12 in a chaotic manner. At this time, the coins may be of the same denomination or different denominations.

By inserting a coin into the coin storing portion 15, the detection light of the sensor 54 is shielded to detect the presence of the coin, the motor 26 is operated, and the rotary disc 17 is moved through the torque limiter 25 to the arrow in the figure. It is rotated in the normal direction.

The forward rotation of the rotary disc 17 pushes the protrusion 41 of the arm 39 of the opening / closing means 38 by the end face of the cam 42 to open the shutter 37, and the surface of the rotary disc 17 in the coin pool 15 is opened. One coin in contact passes through the slit portion 30 and advances to the coin passage 32.

At this time, the surface portion of the rotating disc 17 having a large friction coefficient
Since 22 enters the lower surface area of the coin storage section 15, the coin storage section
The coins in 15 are agitated and come into surface contact with the rotary disk 17, and the coins that come into surface contact with the rotary disk 17 are reliably sent to the slit portion 30.

Further, when the rotary disc 17 makes one rotation and returns to the fixed position for rotation, the shutter 37 is once closed, and the amount of coins advancing from the coin reservoir 15 to the coin passage 32 through the slit 30 is regulated. It should be noted that while the coin is passing through the slit portion 30, the shutter is
Even if 37 is closed, the shutter 37 is only closed by the urging force of the leaf spring 44. Therefore, the coins that are passing may be passed through as is, or even if the passing is stopped, the shutter is rotated by the continuous rotation of the rotating disk 17. Pass when 37 is released.

The coins having proceeded to the coin passage 32 are conveyed in the coin passage 32 as the rotary disc 17 rotates. Then, if the regulation member 45 has entered the coin passage 32, the position of the side edge of the front edge in the coin transport direction of the coin is regulated while the coin is located below the terminal end of the thickness guide plate 33. Abutting on the member 45, the conveyance is restricted. By pushing up the cam roller 49 by the protrusion 51 of the cam 50 of the operating means 46, the regulating member 45 is moved to the coin passage.
Escape from inside 32 and allow coins to pass. Further, when the projection 51 of the cam 50 passes the position of the cam roller 49, the regulation member 45 re-enters the coin passage 32 to regulate the passage of the succeeding coins that have passed therethrough. The restriction member 45
When the coin enters the coin passage 32 and the tip of the restricting member 45 comes into contact with the coin, the restricting member 45 is simply closed by the urging force of the leaf spring 52. However, since the frictional resistance between the upper surface of the rotating disk 17 and the coin is larger, the coin that is passing passes through as it is.

The coins, which are allowed to pass through the coin passage 32, are discharged to the coin processing unit 61 through the discharge port portion 31, and the coin processing unit 61 is discharged.
At 61, the identification and counting process is performed.

Then, by restricting the passage of coins by the regulating member 45 and sending out one coin at a constant interval,
The sending speed can be set according to the speed at which the coin processing unit 61 can perform the sorting and counting processes one by one, and even if there is a variation in the interval from the coin pool 15 to the coin passage 32 through the slit 30. The delivery interval can be made substantially constant.

The rotation direction of the rotary disc 17 is set to prevent coin jamming in the slit portion 30, the coin passage 32, etc.
Reverse rotation is also automatically performed at an appropriate timing and time width. Furthermore, when a large load equal to or greater than a certain torque is applied to the rotating disc 17, the torque limiter 25 operates to slip the driving force from the motor 26 to the rotating disc 17, so that the finger is mistakenly placed in the coin collecting portion. It is safe to put it in 15 and come into contact with the rotating disk 17.

When all the coins in the coin storing section 15 have been sent out, when the rotary disc 17 passes through the fixed rotation position,
Since the detection light is projected and received by the sensor 54 through the window 23 of the rotary disc 17, no coin is detected. When no coins are detected, the rotating disk 17 reaches a fixed position for rotation and the detection light is projected and received by the sensor 54 through the window hole 23 after a time period in which the coins remaining in the coin passage 32 can be reliably delivered. When this happens, the motor 26 is stopped and the rotary disc 17 is stopped at the fixed rotation position.

When a power failure occurs in the standby state, when not picking up the power failure and erroneously inserting coins into the coin pool 15, the surface portion 21 of the rotating disk 17 having a small friction coefficient is removed.
Faces the lower surface area of the coin storing portion 15, so that the coin can be easily taken out while sliding on the upper surface of the rotating disk 17. Moreover, since the slit portion 30 is closed by the shutter 37, it is possible to prevent coins from entering the machine.

The deformed coins and the foreign matters put into the coin storing portion 15 are not limited to the rotating disc 17, the slit portion 30 and the thickness guide plate.
If it cannot be processed even by automatic reverse rotation of the rotating disk 17, the slit part 30
Alternatively, the thickness guide plate 33 may be removed by slightly opening it from the rotary disc 17.
