Description

Coin identification counter

The present invention relates to a coin discriminating / counting machine that identifies and counts denominations of coins and detects and eliminates false coins.

Generally, a company having a plurality of stores, such as a convenience store, collects sales from each store by a collection method or a collection agent of the company by a predetermined method.

When collecting the money, the person in charge of collecting money or the collection agent often collects the data separately from the sales amount already recorded by each store, such as the register of each store.

During this counting, coins may be counted by a coin identification counter. As an example of this type of conventional coin identification counter, the number of coins is counted for each denomination by inserting mixed coins in which a plurality of denominations are mixed into the hopper, and the total amount is also calculated. What is calculated and displayed on the display unit is known (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 8-110961

DISCLOSURE OF THE INVENTION However, generally, when there are stores with a large number of coins and stores with a small number of coins depending on the store, and the number of coins is small, when the conventional coin identification counter is used, the coin identification and counting process is slow. There is a problem.

That is, in this conventional coin identification counter, regardless of the number of coins inserted into the hopper, it is conveyed to the coin outlet through the denomination identifying means and the coin counting means by the belt conveyor and the conveying device. Even if there is little, there exists a subject that the coin identification count processing speed cannot be raised.

The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a coin identification counter that can increase the coin identification counting processing speed when the number of coins is small.

The present invention provides a first hopper that receives a coin and discharges the coin from a first discharge port, and a rotation that receives the coin discharged from the first discharge port and conveys it in a centrifugal direction by a rotational force. A rotating disk device having a disk and a coin discharge port for discharging the coins conveyed in the centrifugal direction one by one; and a conveying device for conveying the coins discharged from the coin discharge port one by one to the coin outlet through the conveying path A denomination identifying unit that is disposed in the middle of the transport path and identifies a denomination of coins, a false coin detection unit that is disposed in the middle of the transport path and detects a false coin, and the denomination identifying unit At least one of the different denomination coins when a different denomination different from the designated denomination set in advance is detected and the counterfeit coins detected by the counterfeit coin detection means is discharged to the exclusion port It is arranged in the middle of the conveyor It is the coin identification counting machine, characterized in that anda coin counting means for counting the coins being.

According to the present invention, when the number of coins is small, when the coins are inserted into the first hopper, they are discharged directly to the turntable device without passing through the second transport device such as a belt conveyor. As a result, it is possible to speed up the coin identification and counting processing speed by the coin identifying means, the coin counting means, and the like as long as the time to be conveyed to the turntable device can be omitted.

And in the said invention, the rotation which receives the coin discharged | emitted from the 2nd discharge port of the 2nd hopper which receives the insertion of a coin and discharges the coin from the 2nd discharge port, and this 2nd hopper receives the said rotation It is desirable to comprise the 2nd conveying apparatus conveyed on a board. According to this, when the number of coins is large, by inserting the coins into the second hopper, the coins are transported to the turntable device by the second transport device such as a belt conveyor and the coin identification counting process is performed. Can do.

That is, if the coins put into the second hopper are discharged directly to the turntable device without going through the second transport device, a large amount of coins is put into the second hopper at once. In addition, there is a possibility that coins may be clogged in the second discharge port.

However, when coins thrown into the second hopper are discharged from the second discharge port, they are received by the belt conveyor and conveyed to the rotating disk device, so that the second discharge port is connected to the belt conveyor. The size can be increased according to the size. As a result, it is possible to reduce the clogging of coins at the second discharge port, so that the second hopper itself can be increased in size.

For this reason, when the number of coins to be identified and counted is large, it can be processed in large quantities by using the second hopper, and when the number of coins is small, by using the first hopper. The processing speed can be increased.

Further, according to this coin identification counter, the false coins can be excluded from the genuine coins by the exclusion device.

Further, in the invention, the transport device includes a transport path surface that slides one surface of the coin, and a guide that is disposed on at least one side in the width direction of the transport path surface and slides the peripheral surface of the coin to guide the transport direction. A wall, a conveyor belt that elastically presses one surface of the coin toward the conveyance road surface, and conveys the coin in the direction of conveyance in a row, and a plurality of the conveyor belts disposed along the coin conveyance direction. It is desirable to include a roller that individually supports the coins so that they can rotate and elastically press the coins toward the conveyance road surface. According to this, since the conveyance path surface is formed on the sliding surface that slides one surface of the coin, the sliding resistance can be reduced and the efficiency of coin transportation can be improved. As a result, it is possible to reduce the driving force of the conveyor belt that conveys the coin by pressing one surface of the coin against the sliding surface.

In addition, since the side circumferential surface of the coin is slidably brought into contact with the guide wall to guide the coin conveyance direction, the accuracy of the coin conveyance direction and the conveyance efficiency can be improved.

Furthermore, since the plurality of rollers that rotatably support the transport belt are individually individually suspended, etc., each of the rollers is elastically pressed to the transport road surface side. Even when the thicknesses are variously different, the coins can be transported in a state where the coins are always elastically pressed toward the transporting road surface by the elastic force according to the thickness.

For this reason, the transfer efficiency and accuracy of coins can be further improved.

In the present invention, it is preferable that the transport device includes a road surface side pressing device that is embedded in the transport road surface and that can slide coins and elastically press the coin toward the transport belt. According to this, since a coin is conveyed in the state which clamped both surfaces of the coin elastically with the road surface side pressing device and conveyance belt of a conveyance path, the coin holding power by a conveyance belt can be improved. For this reason, it can reduce that a conveyance belt slips on a contact surface with a coin, and conveyance efficiency falls. Further, it is possible to prevent or reduce the overlap of some of the coins before and after the conveyance direction due to the difference in the thickness of the coins.

Furthermore, in the above-mentioned invention, it is desirable to provide a batch stopper device for stopping the discharging of coins to the coin outlet when the preset number of sheets is counted by the coin counting means. According to this, batch processing such as coin identification counting can be performed.

In the invention, the batch stopper device includes a batch stopper that forcibly prevents coins from sliding on the conveying path when the preset number of sheets is counted by the coin counting means. It is desirable to do. According to this, when the processing such as coin identification counting is completed by the batch processing, the movement of the coin sliding on the transport path can be forcibly blocked by the batch stopper.

Further, in the above invention, the exclusion device is configured to detect the different denomination coins and the false coins detected by the counterfeit coin detection unit when the different denominations different from the designated denomination set in advance by the denomination identification unit are identified. It is desirable to provide an exclusion guide that guides at least one of the false coins when detected to the exclusion port. According to this, since the different denominations identified by the denomination identifying means or the false coins detected by the counterfeit coin detecting means are guided and eliminated by the exclusion guide, the different denominations or false coins are recognized as coins. In addition to being able to prevent or reduce discharge to the outlet, it is possible to easily and reliably distinguish between a designated denomination and a different denomination, or a counterfeit coin and a true coin.

In the invention described above, a display device may be provided that displays the number of coins counted by the coin counting unit, the denomination identified by the denomination identifying unit, the number of denominations, and the total denomination amount. desirable. According to this, the number of coins, denominations, the number of each denomination, and the total amount are displayed on the display device. By visually checking the display, the number of coins, the denomination and the number of each denomination The total amount can be easily and reliably recognized.

This coin storage bag is configured to be detachably attached to the chute body 5a.

As shown in FIG. 3, on the side surface of the main casing 2, a drawer-shaped excluded coin storage box 7 for storing a different denomination other than the designated denomination or a fake coin is disposed. A driving operation unit (not shown) is provided on the front surface of the main casing 2. This driving operation unit has operating tools such as a plurality of operating buttons for setting various operating modes of the coin identification counter 1. As the operation mode, for example, a counting mode in which the number of coins 8 is simply counted, when counting of a preset number of coins is completed, the counting is stopped, or an arbitrary denomination and number are set (designated) in advance. There are a batch processing operation mode for stopping the counting when the set number of the designated denomination is counted, a mode for counting the number of each denomination and calculating the total amount.

As shown in FIGS. 1 to 5, the large hopper 3 has, for example, a rectangular planar shape and is formed in a square pyramid-shaped square tube that gradually expands upward in FIG. 2, and an upper end 3a of the rectangle.

On the other hand, the auxiliary hopper 4 is also formed in the shape of a truncated pyramid having a substantially rectangular shape, like the large hopper 3, and its upper surface is opened as a coin insertion slot 4a, and its lower surface (bottom surface) is a coin. The first discharge port 4b is opened.

However, the dimensions of the coin inlet 4a and the first outlet 4b of the auxiliary hopper 4 are smaller than those of the coin inlet 3a and the second outlet 3b of the large hopper 3, respectively.

As shown in FIGS. 7 and 8, the first discharge port 4 b of the auxiliary hopper 4 opens directly above the turntable 10 without passing through the belt conveyor 9 or the like. Coins are dropped directly onto the coin dropping unit 10b.

As shown in FIGS. 6 to 8, the turntable 10 rotates around the central axis O at a required rotation speed, for example, clockwise in FIG. 9, and rotates the coin 8 on the turntable 10 to rotate the coin 8. Gives rotational force and centrifugal force. An annular side wall 11 is disposed concentrically on the outer periphery of the turntable 10 to constitute a turntable device 10c.

As shown in FIG. 9, the annular side wall 11 is constituted by a double wall of an annular inner wall 11a and an annular outer wall 11b, and a coin discharge port for discharging a coin 8 in the centrifugal direction to a part (lower right in FIG. 9). 11c is opened.

The coin discharge port 11c is formed in such a size that the thickest coin 8 and the large-diameter coin 8 among the genuine coins are discharged, and a conveying device is provided at both ends of the coin discharge port 11c. Twelve elongated belt-like conveying belts 13 are provided with start end portions 13a and columnar guide pins 14 respectively.

That is, the start end 13a of the conveyor belt 13 is disposed at the upstream end of the coin discharge port 11c in the rotation direction of the rotating disk 10, and the guide pin 14 is disposed at the end of the coin discharge port 11c at the downstream side in the rotation direction. It is installed.

Therefore, the side peripheral surface of one coin 8 thrown in the centrifugal direction from the coin discharge port 11c can be abutted against the guide pin 14 and guided to the transport path 15 side by the reaction.

The conveyance path 15 has a conveyance path surface 15a that connects the coin discharge port 11c and the genuine coin outlet 16 in a substantially straight line. The conveyance path surface 15 a is formed on a sliding surface that slides one surface of the coin 8.

The width direction dimension W of the conveyance path surface 15a is formed to a size that substantially matches the diameter of the coin 8a having the largest diameter, and a pair of linearly inner and

outer guide walls

16a and 16b are formed on both sides in the width direction. It is arranged in parallel over substantially the entire length of the conveyance path surface 15a, and can be conveyed from the largest diameter coin 8a to the smallest diameter coin 8b. The inner side surfaces of the pair of left and

right guide walls

16a and 16b are formed as sliding surfaces on which the side peripheral surface of the coin 8 can slide.

As shown in FIG. 9, the conveyance belt 13 has a width direction dimension that is smaller than the smallest diameter coin 8 b of genuine coins, and slightly toward the inner guide wall 16 a side from the width direction center of the conveyance path 15. It is arranged at a position displaced.

For this reason, in a state where the side peripheral surface of the coin 8b with the smallest diameter is slidably contacted with the inner surface of the inner guide wall 16a, the substantially central portion of the coin 8b with the smallest diameter is elastically elastic in the diameter direction by the conveyor belt 13. Can be retained.

The conveying belt 13 is formed over substantially the entire length of the conveying path 15, and is formed into an endless belt by forming an elastic belt-like belt body having elasticity as shown in FIG. At least one of the parts is wound around the drive pulley 17, and the other end is wound around a drive pulley or a driven pulley (not shown).

Further, the conveying belt 13 requires a plurality of

rollers

These

rollers

18, 18,... Are individually suspended from the belt inner surface of the end of the transport belt 13 on the transport path surface 15a side (the lower end in FIG. 10) while being elastically pressed toward the transport path surface 15a. The coins 8 are elastically pressed one by one toward the conveyance path surface 15a via the conveyance belt 13 every 18 and are elastically pressed according to the difference in various thicknesses of the coins 8.

Furthermore, as shown in FIG. 10, a plurality of road surface side pressing devices 19 are arranged on the transport road surface 15a with a required pitch in the longitudinal direction on the central axis.

Each road surface side pressing device 19 includes a buried hole 19a formed in the conveying road surface 15a, a coiled spring 19b accommodated in the buried hole 19a, and a ring-shaped upper end portion of the spring 19b by fitting or the like. And a metal ball 19c fixedly or rotatably mounted.

Each ball 19c is formed with a sphere diameter sufficiently smaller than the diameter of the coin 8b with the smallest diameter, and is embedded in the embedding hole 19 with its head protruding slightly upward from the conveyance path surface 15a. The coin 8 sliding on the conveyance path surface 15a is elastically pressed so as to be slidable toward the conveyance belt 13 side.

As shown in FIG. 9, an identification counting device 20 is disposed in the middle of the conveyance path 15, for example, in the middle in the longitudinal direction.

The identification counting device 20 includes a denomination identifying means for identifying the denomination of each coin 8 passing through the conveyance path 15, a false coin detecting means for identifying a false coin and a true coin, and detecting a false coin, and a true coin. And coin counting means for counting the number of each denomination.

That is, the discriminating / counting device 20 is an optical sensor (not shown), a magnetic sensor, and a control unit that reads detection results of the optical sensor and the magnetic sensor, detects false coins, and counts the number of genuine coins (number of coins). It has.

The optical sensor is a light emitting element such as an LED (light emitting diode) that irradiates each coin 8 passing through the transport path 15 and a linear CCD (charge) that receives the projection when the coin 8 is projected by the light emitting element. A light receiving element such as a coupling element) is provided, and the projection pattern of the coin 8 is detected.

Also, the magnetic sensor applies a magnetic field to each coin 8 passing through the transport path 15 and detects its magnetization pattern.

The control means is composed of, for example, a microprocessor or the like, and includes a memory such as a RAM that stores the projection pattern and the magnetization pattern for each denomination of the genuine coin 8 as a reference pattern or a reference pattern, and the optical sensor and the magnetic sensor. By detecting the shape, size, material, etc. of the coin 8 by pattern matching that compares the read projection pattern and magnetized pattern with each reference or reference pattern read from the memory, detection of fake coins and different denominations A CPU (central processing unit) for identifying the denomination of the genuine coin 8, counting the number of denominations, and the like, and a ROM (not shown) storing a processing program for driving the CPU are provided.

Further, the CPU has a function of displaying on the display device 6 necessary information including the presence / absence and number of false coins and different denomination coins detected here, the mere number of genuine coins or the number of each denomination.

The identification counting device 20 includes a pair of

air nozzles

21 and 21. These

air nozzles

21 and 21 blow clean air to the sensor surface of the optical sensor or magnetic sensor at a predetermined pressure to blow off foreign matters such as dust and metal powder, and prevent these foreign matters from adhering to the sensor surface. Reduce.

These

air nozzles

21 and 21 are connected to compressors 22 and 22 for supplying clean air via

air hoses

21a and 21a.

A batch number stopper device 23 and a rejection device 24 are respectively arranged in the middle of the conveyance path 15 on the downstream side in the conveyance direction from the identification counting device 20.

As shown in FIG. 11, the batch number stopper device 23 can be rotated on the batch stopper timing sensor 25 embedded on the conveyance path surface 15 a and on the outer guide wall 16 b side downstream of the batch stopper timing sensor 25 in the conveyance direction. And a batch stopper 26 disposed on the surface.

The batch stopper timing sensor 25 is composed of, for example, an optical sensor, and gives the detection result to the microprocessor of the control means when the passage of the coin 8 is detected.

The microprocessor finishes counting the number of coins 8 set in advance by an operation unit (not shown) or counts the set number of arbitrary denominations set (designated). Thereafter, when the passage of the last coin 8 that has passed when the counting is completed is detected by the batch stopper timing sensor 25, an ON (operation) signal is given to the batch stopper 26 at the time (timing) when the passage is detected. .

The batch stopper 26 has a solenoid (not shown) that operates each time an on / off control signal is input from the microsensor, and rotates so that the standby position OFF and the cutoff position ON can reciprocate. These are held at these two positions. That is, when an on signal is given from the microprocessor to the solenoid, the solenoid rotates the batch stopper 26 to the cutoff position ON, and when the off signal is given to the solenoid, the batch stopper 26 is moved to the standby position OFF. Return.

The batch stopper 26 is held at the cutoff position ON and the standby position OFF until the opposite signal is input to the solenoid. When the batch stopper 26 rotates to the cut-off position ON, the tip of the batch stopper 26 protrudes on the conveyance path 15 to block the conveyance path 15 and guides the coin 8 that is conveyed next after the batch counting is completed to the inner guide. It can be pushed into the inner surface side of the wall 16a and the conveyance of the coin 8 can be forcibly stopped. When the batch stopper 26 is moved to the cutoff position ON, the microprocessor forcibly stops the operation of the turntable 10 and the conveying device 12. On the other hand, when returning the birch stopper 26 to the standby position OFF again, the microprocessor restarts the operation of the turntable 10 and the conveying device 12 again. For this reason, the conveyance path 15 is opened again, and the coin 8 can be conveyed.

As shown in FIGS. 11 to 14, the rejection device 24 includes an exclusion port 27, a rejection trigger sensor 28, a rejection lever 29, and a rejection lever 29 that are formed downstream of the batch stopper 26 in the transport direction. An exclusion lever driving device 30 that drives each of the standby positions T is provided.

The exclusion port 27 is formed substantially concentrically with the conveyance belt 13 in the conveyance road surface 15a, and has a width slightly smaller than the diameter of the smallest diameter coin 8b among the true coins and the largest diameter coin 8 among the true coins. The upstream end portion in the transport direction is formed in a substantially triangular shape that tapers toward the upstream side.

The reject trigger sensor 28 is composed of, for example, an optical sensor or the like. When at least one of the false coin and the different denomination is detected by the microprocessor, the rejection trigger sensor 28 detects the transfer position of the false coin or the different denomination, and the false coin. And a position detection signal of at least one of the different denominations is supplied to the microprocessor.

The tip of the reject lever 29 is bent, for example, like a bowl, and the head 29a of the tip is driven by the reject lever driving device 30 so that it slightly protrudes and retracts from an intrusion hole 29b formed in the conveying path surface 29a. . The in / out hole 29 b is formed in the transport path surface 15 a slightly upstream of the upstream end of the exclusion port 27.

FIG. 14 (A) shows a state where the tip end head portion 29a of the reject lever 29 is in the standby position T where the tip end portion 29a is immersed in the intrusion hole 29b, and FIG. A state in which a required length protrudes from the conveyance path surface 15a from 29b to the exclusion position R for guiding the false coin or the different denomination 8X to the exclusion port 27 is shown.

12 (A) to 12 (C), the detection lever sensor 28 shown in FIGS. 11 to 14 detects a relatively large-diameter fake coin or a different denomination 8Xa indicated by diagonal lines in FIG. (A) shows the timing at which the position of the large-diameter fake coin or the different denomination 8a is detected by the reject trigger sensor 28; B) shows the timing from the start to the completion of the operation of projecting the reject lever 28 onto the conveyance road surface 15a, and (C) shows that the large-diameter fake coin or the different denomination 8Xa collides with the reject lever 29, and the reaction further The timing which collided with the inner surface of the outer guide wall 16b on the opposite side is shown.

That is, as shown in FIG. 12 (A), when the leading end 29a of the reject lever 29 protrudes a required length on the conveying path surface 15a, the reject lever leading end 29a is hatched as shown in FIG. 12 (B). The counterfeit or different denomination 8Xa shown collides with the left end in FIG. 12, that is, one end near the inner guide wall 16a from the center thereof.

Due to the reaction at the time of the collision, the false coin or the different denomination 8Xa is repelled toward the outer guide wall 16b as shown in FIG. 12C, and the false coin or the different denomination 8Xa is further moved to the inner surface of the outer guide wall 16b. It is repelled to the inner guide wall 16a side, falls into the exclusion port 27 in the middle, and is stored in the false coin storage box 7 in the middle.

Also in the case of a fake coin or a different denomination 8Xb having a small diameter, as shown in FIGS. 13A to 13C, a small-diameter fake coin or a different denomination 8Xb indicated by diagonal lines in FIG. It is excluded into the exclusion port 27 and accommodated in the excluded coin storage box 7 by substantially the same action as the large-diameter fake coin or the different denomination 8Xa shown in C).

The genuine or set (designated) denomination coins 8 after the false coins or the different denominations 8Xa and 8Xb are eliminated in this manner do not hit the reject lever tip portion head 29a. Go straight, slide on the intrusion hole 29b in which the reject lever tip head portion 29a is immersed and the exclusion port 27 sequentially, and further conveyed to the coin outlet 16 of the genuine coin or the specified denomination by the conveyor belt 13, It is discharged to the discharge chute 5 and stored in a coin storage bag (not shown).

Further, according to the operation mode selected by the operation unit (not shown), the number of coins 8 is simply counted, the number set in advance by batch processing is counted, or the set number of designated denominations is counted, or The number of denominations and the total amount are calculated by the microprocessor and displayed on the display unit 6.

Therefore, according to this coin identification counter 1, when the number of coins 8 to be counted is small, the coins 8 are inserted into the auxiliary hopper 4 which is the first hopper, without going through the belt conveyor 9. It can be discharged directly onto the turntable 10. For this reason, the coin discriminating / counting speed of the discriminating / counting device 20 can be increased by the amount that the time required for the coin 8 to be conveyed to the turntable device 10c by the belt conveyor 9 can be omitted.

Further, when the number of coins 8 to be counted is large, the coins 8 are loaded into the large hopper 3 so that the coins 8 are transported in large quantities to the turntable 10 by the second transport device 9 such as a belt conveyor. Identification counting processing can be performed.

That is, if the coins 8 inserted into the large hopper 3 are discharged directly to the rotating disk 10 without going through the belt conveyor 9, a large amount of coins 8 are inserted into the large hopper 3 at once. Then, there is a possibility that the coin 8 may be clogged with the rotating disk 10.

However, when the coin 8 put into the large hopper 3 is discharged from the second discharge port 3b, the coin 8 is received by the belt conveyor 9 and sequentially conveyed onto the turntable 10. 8 can be prevented. Moreover, since this 2nd discharge port 3b can be enlarged according to the magnitude | size of the belt conveyor 9, it can reduce that the coin 8 is blocked by the 2nd discharge port 3b. For this reason, the large hopper 3 itself can also be enlarged.

For this reason, when the number of coins to be identified and counted is large, the large number of hoppers 3 can be used for identification and counting, and when the number of coins is small, the auxiliary hopper 4 can be used. The identification counting processing speed can be increased.

Further, according to this coin identification counter 1, the false coin or the different denomination 8X can be excluded from the genuine coin by the exclusion device 24.

Furthermore, since the conveyance path surface 15a is formed on a sliding surface for sliding one surface of the coin 8, the sliding resistance can be reduced and the efficiency of coin transportation can be improved. As a result, it is possible to reduce the driving force of the conveyor belt 13 that conveys coins by pressing one surface of the coin 8 against the sliding surface 15a.

Further, since the side circumferential surface of the coin 8 is slidably brought into contact with the pair of inner and

outer guide walls

16a and 16b to guide the conveyance direction of the coin 8, the accuracy and conveyance efficiency of the coin 8 in the conveyance direction can be improved. it can.

Further, the plurality of

rollers

18, 18,... That rotatably support the transport belt 13 individually elastically press the coin 8 toward the transport road surface 15 a side by being individually suspended individually. Even when the thickness of the coin 8 varies due to the difference in denomination, the coin 8 is always conveyed in a state where the coin 8 is elastically pressed toward the conveyance road surface 15a side by the elastic force corresponding to the thickness. Can do.

Further, since the coin 8 is transported by the road surface side pressing device 19 and the transport belt 13 of the transport path 15 while elastically sandwiching the front and back surfaces of the coin 8, the coin holding force by the transport belt 13 can be improved. . For this reason, it can reduce that the conveyance belt 13 slips on a contact surface with the coin 8, and conveyance efficiency falls. Further, it is possible to prevent or reduce the overlap of some of the coins 8 before and after the conveyance direction due to the difference in thickness of the coins 8.

Moreover, since the identification counting device 20 stops the conveyance of the coin 8 by the conveyance device 12 by the batch stopper device 23 when counting the preset number of sheets, the batch processing such as the coin identification counting is surely executed. be able to.

Furthermore, when the batch processing is completed, the batch stopper 26 can forcibly prevent the coin 8 sliding on the conveyance path 15 from sliding.

Further, since the false coin or the designated denomination 8X detected by the identification counting device 20 is guided by the reject lever 24 to the exclusion port 27, the false coin or the designated denomination 8X is discharged to the coin outlet 16. In addition to being able to prevent, it is possible to easily and reliably distinguish between the fake coin or the different denomination 8X and the genuine coin 8, and the designated denomination 8X and the different denomination.

Furthermore, since the number of coins 8 and the denomination, the number of each denomination, and the total amount of these are displayed on the display unit 6, the number of coins 8, the denomination and the denomination can be determined by viewing the display. The number of seeds for each species and the total amount can be easily and reliably recognized.

The display unit 6 may also be configured to display the number of fake coins or different denominations 8X detected by the identification counting device 20.

If the number of coins to be counted is small, when the coins are inserted into the first hopper, they are discharged directly onto the rotating disk without going through the belt conveyor. As much as it can be omitted, the coin identification and counting processing speed by the identification and counting device can be increased.

Further, when the number of coins to be counted is large, the coins are transferred to the turntable by a second transfer device such as a belt conveyor by inserting the coins into the second hopper. Counting can be performed.

Therefore, according to this coin identification counter, when the number of coins to be identified and counted is large, the second hopper can be used to process a large amount, and when the number of coins is small, the first By using this hopper, the coin identification counting processing speed can be increased.
