In the automatic change dispensing device 1 of the first embodiment having the above-described structure, as shown in FIG. 3, the cam rollers of the coin storing and dispensing mechanism 14 provided on the tip side of each coin storing portion 12 are arranged. 17 is the reference position of the cam portion 17
a is a position in which a coin storage space wider than the thickness of one coin is formed between the head coin of the coin row 15 formed of coins stored in each coin storage portion 12, and in this state, from the coin slot 5 Waiting for coins to be inserted or change data to be input from the cash register. In addition, each motor 3
6, 37, 38, solenoids 2 for driving shutter members
0 and the distribution mechanism 32 are de-energized, each shutter member 18 closes the coin outlet 13, and the distribution mechanism 32 is stopped at a position where the discharged coins are distributed to the coin payout outlet 6 side. .

Now, when a coin is inserted from the coin insertion slot 5, a coin detection pulse signal is input from the coin insertion sensor 34. Then, the CPU 41 executes the coin storing process shown in the flowchart of FIG. That is, first, S
When it is detected that a coin has been inserted from the coin insertion slot 5 by the coin detection pulse signal from the coin insertion sensor 34 as T (step) 1, the motor drive circuit 4 is set as ST2.
The energization ON signals are sequentially sent from 9 and 50 to operate the closing motor 36 and the carry motor 37.

Then, the insertion belt 24 is driven by the operation of the insertion motor 36, and the coins inserted from the coin insertion port 5 are conveyed one by one to the rear side of the front cover 4.
Further, the conveyor belt 26 is driven by the operation of the conveyor motor 37, and the coins conveyed to the rear side of the front cover 4 are further regulated in a line along the guide plate 25 to a position above the coin storing and dispensing mechanism 14. It is transported in a horizontal position while it is held.

At this time, the CPU 41 causes the coin transport sensor 3
The number of coins conveyed is counted and managed by counting the number of pulses of the coin detection pulse signal from 5. Now, the coins transferred to the position above the coin storing and dispensing mechanism 14 are
The coin storage holes 27-1 to 27-6, which have the same size, drop from the coin selection holes 27-1 to 27-6 and are in an upright posture.
Is guided to the coin storage space formed by the cam portion 17a.

At this time, the CPU 41 monitors the sensor signal input circuit 56 which stores and holds the coin material detection signals from the coin material sensors 29 in the order of input in ST3, and detects the coin material from any coin material sensor 29. When the signal is detected, the inserted coins are sorted by the coin sorting holes 27-1 to 27-6 corresponding to the coin material sensor 29.
4, the motor drive circuit 51 outputs an energization ON signal to operate the storage / delivery motor 38.

As a result, the roller member 16 and the pair of cam rollers 17 of the coin storing / discharging mechanism 14 rotate clockwise in FIG. 3, and the inserted coin guided in the coin storing space in an upright posture rotates the roller member 16. It is pushed down by frictional force. Then, when the roller member 16 and the pair of cam rollers 17 are rotated about half a turn, the inserted coins are stored such that the leading coins of the corresponding coin rows 15 of the coin storing portion 12 and the surfaces of the coins overlap each other.

On the other hand, the CPU 41 causes the coin material sensor 29 which is the source of the coin material detection signal detected in ST5.
In addition to recognizing the type of coins to be selected in the coin selecting holes 27-1 to 27-6 corresponding to, the coin material detection signal is analyzed to recognize the material of the inserted coin. Then, by searching the coin-based material table 58, the corresponding coin selection hole 27-1
27-6, it is determined whether the preset material for the coin to be sorted matches the material of the inserted coin (material determining means).

As a result, when the material preset in the coin-specific material table 58 and the material of the inserted coin match, it is recognized that the inserted coin is correctly selected by the coin selecting holes 27-1 to 27-6. As ST11, the roller member 16
When the cam portion 17 returns to the reference position after waiting for one rotation of the pair of cam rollers 17, the energization ON signal to the motor drive circuit 51 is turned off in ST12 to store / store.
The operation of the payout motor 38 is stopped.

On the other hand, if it is determined in ST5 that the materials do not match, it is recognized that the inserted coins have not been correctly selected by the coin selection holes 27-1 to 27-6, and the inserted coins are stored in ST6. Coin outlet 1 of the coin storage unit 12
An energization ON signal is output to the driving solenoid 20 of the shutter member 18 that has closed the shutter 3, and the shutter member 18 is opened. Also, as ST7, the distribution mechanism 3
2 is switched to the coin receiving container 31 side (missorted coin reject means).

As a result, the inserted coin pushed down by the rotational frictional force of the roller member 16 is ejected from the coin ejection port 13 without being accommodated in the coin accommodating portion 12, and is guided to the coin receiving container 31 side by the sorting mechanism 32. The coin is then stored in the coin receiving container 31.

Then, the CPU 41 monitors the coin detection pulse signal of the discharge coin sensor 33 provided in the coin discharge port 13 of the corresponding coin storage portion 12 in ST8. Then, if it is confirmed that the discharged coin sensor 33 detects a coin, the coin detection pulse signal rises, and then the coin passes and the coin detection pulse signal falls, ST
At 9, the energization ON signal to the shutter solenoid 20 is turned off to close the shutter member 18, and at ST10, the sorting mechanism 32 is moved to the coin payout port 8.
Put it back to the side.

Thereafter, the CPU 41 waits for the roller member 16 and the pair of cam rollers 17 to make one rotation in ST11, and if the cam portion 17 returns to the reference position, S11.
At T12, the energization ON signal to the motor drive circuit 51 is turned off to stop the operation of the storage / delivery motor 38.

Thereafter, the CPU 41 returns to the determination processing of ST3, and repeats the processing of ST4 to ST12 each time the coin material detection signal from any of the coin material sensors 29 is detected. Further, the CPU 41 counts and manages the number of coins stored by counting the number of input coin material detection signals from each coin material sensor 29. If the number of stored coins matches the number of coins transferred,
At ST13, it is determined that the coins have been conveyed, and at ST14
As a result, the energization ON signal to the motor drive circuits 49 and 50 is turned off to stop the operation of the input motor 36 and the carry motor 37.

As described above, the coin storing process of this time is completed, and thereafter, every time a coin is inserted from the coin slot 5, the above ST
The processes of 1 to ST14 are repeated.

When the change dispenser 1 receives change data from the cash register connected via the communication interface 44, the change dispenser 1 calculates the number of coins to be paid out based on the change data and pays out the coins. The solenoid 20 for driving the shutter member corresponding to the coin storing portion 12 in which the coins are stored is turned on to open the corresponding shutter member 18. Further, the storage / delivery motor 38 is operated only for the time required for the roller member 16 and the pair of cam rollers 17 to rotate once.

As a result, the leading coin in the stored coin row is pushed down by the rotational frictional force of the roller member 16 from the coin storing portion 12 with the shutter member 18 opened, and is discharged from the coin discharging port 13. At this time, the sorting mechanism 32 is stopped at a position that guides the discharged coin to the guide body 30 side, and the coin discharged from the coin discharge port 13 is
The coins are paid out to the coin payout exit 14 along the guide body 30.
After that, the opening / closing operation of the shutter member 18 and the rotating operation of the roller member 16 and the pair of cam rollers 17 are repeated until the required number of coins to be paid out are paid out.

As described above, in the automatic change dispensing device 1 according to the first embodiment, the coin sorting holes 27-1 to 27-1 to sort the coins inserted from the coin slot 5 according to the size of the coins.
A coin material sensor 29 for detecting the material of coins dropped from the coin selection holes 27-1 to 27-6 is provided on the lower side of 27-6, and the coins are selected by the corresponding coin selection holes 27-1 to 27-6. The coin material to be inserted is compared with the coin material detected by the coin material sensor 29, and when they do not match, it is recognized that the inserted coin has been erroneously selected by the coin selection holes 27-1 to 27-6, and this coin is inserted. Since the coins are removed from the coin receiving container 31 without being stored in the coin storing portion 12, the input coins are stored in the coin storing portion 12 while being incorrectly selected by the coin selecting holes 27-1 to 27-6. , It is possible to prevent the change from being paid out.

Further, a false coin having the same shape and size as a valid coin may be illegally used and inserted from the coin insertion slot 5. Even in such a case, the valid coin and the material are Different fake coins can be reliably eliminated without storing. As a result, the change amount paid according to the change data from the cash register -1 to 27-6 always matches the actual change amount, and the reliability of the device can be improved. Further, since it is not necessary to check whether the change amount is correct or whether false coins are mixed, it is possible to reduce the burden on the user.

Next, a second embodiment will be described with reference to FIGS. In addition, in the automatic change dispensing device according to the second embodiment, the sorting mechanism 32, which is commonly provided for each coin storage unit 12 in the automatic change dispensing device 1 according to the first embodiment, is used for each coin. Coin outlet 1 of storage section 12
3 is provided separately from each other, and the distribution mechanism drive circuit 52 is individually provided in correspondence therewith, except that the automatic change dispensing device 1 of the first embodiment has the same hardware configuration. Therefore, the description thereof will be omitted with reference to FIGS.

Now, in the automatic change dispensing device according to the second embodiment, as shown in FIG.
Bit data indicating whether the coins stored in each coin storage unit 12 are correctly selected in the coin selection holes 27-1 to 27-6 or incorrectly selected (0: positive,
The storage coin memory 80 is formed so as to store the respective (1) erroneous numbers according to the number of stored coins.

When a coin is inserted from the coin insertion slot 5 and a coin detection pulse signal is input from the coin insertion sensor 34, the CPU 41 executes the coin storing process shown in the flowchart of FIG. Incidentally, ST21 to ST24 are the same as ST1 to ST4 of the coin storing process in the first embodiment. That is, the coin insertion sensor 34
When it is detected that a coin has been inserted from the coin insertion slot 5 by the coin detection pulse signal from (ST21), the motor drive circuits 49 and 50 sequentially send the energization ON signals to operate the insertion motor 36 and the carry motor 37. (ST22). Then, the number of coins conveyed by the coin detecting sensor 35 is counted to count and manage the number of coins conveyed. Also, each coin material sensor 2
The sensor signal input circuit 56, which stores and holds the coin material detection signals from 9 in the order of input, is monitored (ST23), and when a coin material detection signal from any of the coin material sensors 29 is detected, the motor drive circuit 51 sends an energization ON signal. Is output to operate the storage / delivery motor 38 (ST24).

Thereby, the inserted coins are in the coin row 1 of the coin storing portion 12 corresponding to the dropped coin selecting holes 27-1 to 27-6.
The top coins of coins 5 and the faces of the coins are stacked and stored.

At this time, the CPU 41 recognizes the types of coins to be sorted by the coin sorting holes 27-1 to 27-6 corresponding to the coin material sensor 29 which is the source of the coin material detection signal detected at ST25. , The stored coin data of the corresponding coin type in the coin storage memory 80 is shifted to the lower order (the side where the number of stored coins is large) by 1 bit. Also, S
At T26, the coin material detection signal is analyzed to recognize the material of the inserted coin. And the coin-based material table 5
No. 8 is searched and it is determined whether or not the preset material and the material of the input coin for the coins to be sorted in the corresponding coin sorting holes 27-1 to 27-6 match (material determining means).

As a result, when the material preset in the coin-based material table 58 and the material of the inserted coin match, it is recognized that the inserted coin is correctly selected by the coin selecting holes 27-1 to 27-6. Then, in ST27, the bit data “0” is stored in the leading area (area where the number of stored coins is “1”) in the coin storing memory 80. On the other hand, if the material preset in the coin-based material table 58 and the material of the input coin do not match, it is recognized that the input coin is not correctly selected by the coin selecting holes 27-1 to 27-6. , ST28 as the coin storage memory 8
Bit data “1” is stored in the leading area (area where the number of stored coins is “1”) of the corresponding coin type 0.

After that, in ST29, the roller member 16 and the pair of cam rollers 17 wait for one rotation, and when the cam portion 17 returns to the reference position, the energization ON signal to the motor drive circuit 51 is turned off in ST30. Then, the operation of the storage / delivery motor 38 is stopped.

When the change data is received from the cash register, the CPU 41 executes the coin payout process shown in the flowchart of FIG. That is, first, in ST31, the number of coins to be paid out of various coins is calculated based on the change data, and all the energization of the shutter member driving solenoids 20 corresponding to the coin storing unit 12 storing the coins to be paid out is turned on. Then, the corresponding shutter member 18 is opened. Further, as ST32, a coin storage unit 1 in which payout coins are stored.
Sorting mechanism 3 provided under the coin outlet 13 of 2 respectively
2 are respectively positioned on the coin payout exit 8 side.

Next, at ST33, the stored coin memory 80
Check the top stored coin data corresponding to the payout coin. Then, at ST34, when a payout coin having the first stored coin data of "1" is detected, the sorting mechanism 32 provided on the lower side of the coin outlet 13 of the coin storing unit 12 storing the payout coin is received. Switch to the container 31 side.

Thereafter, in ST35, the storage / delivery motor 38 is operated for the time required for the roller member 16 and the pair of cam rollers 17 to make one rotation. As a result, the leading coin in the stored coin row is pushed down by the rotational frictional force of the roller member 16 from the coin storing portion 12 with the shutter member 18 opened, and is discharged from the coin discharging port 13. At this time, coins dispensed from the coin storage unit 12 in which the corresponding sorting mechanism 32 is located on the coin dispensing outlet 8 side, that is, coins having coin storage data “0”, are dispensed to the coin dispensing outlet 8 as change. It On the other hand, the coin storing unit 1 in which the corresponding sorting mechanism 32 is located on the coin receiving container 31 side
The coins dispensed from 2, that is, the coins whose coin storage data is “1” are discharged to the coin receiving container 31 and are not dispensed to the change dispensing outlet 8.

Therefore, in ST36, the CPU 41 monitors the coin detection pulse signal of the discharge coin sensor 33 provided in the coin discharge port 13 of the coin storing section 12 storing the dispensed coins. Then, when it is confirmed that the coin detecting pulse signal rises after the coin detecting sensor 33 detects a coin and then the coin passes and the coin detecting pulse signal falls, the leading stored coin data is "0" at ST37. The number of payout coins of "" is counted by "+1".

Thereafter, in ST38, the shutter member driving solenoid 2 for the coin storage portion 12 for the dispensed coins is placed.
The energization to 0 is turned off, and the shutter member 18 of the coin storage unit 12 is once closed. Further, in ST39, the sorting mechanism 32 for the payout coin having the first stored coin data of "1" is returned to the coin payout exit 8 side. Further, the stored coin data corresponding to the dispensed coins in the stored coin memory 80 is shifted to the upper side (the side where the stored number is smaller) by "1" bit. After that, in ST40, the roller member 16 and the pair of cam rollers 17 rotate once, and when the cam portion 17 returns to the reference position, the operation of the storage / delivery motor 38 is temporarily stopped.

The CPU 41 repeats the above-mentioned steps ST31 to ST41 until the number of coins to be paid out matches all the required number of coins calculated based on the change data. And ST
If it is confirmed as 42 that the number of coins to be dispensed is all the required number calculated based on the change data,
Since the change corresponding to the change data has been paid out to the change payout exit 8, this process ends.

Also in the automatic change dispensing device of the second embodiment having such a configuration, the coin sorting holes 27-1 to 27-27 are provided.
Since there is very little possibility that coins misselected in -6 will be paid out as change, the same effect as the automatic change dispensing device 1 of the first embodiment can be obtained.

By the way, generally, in this type of automatic change dispenser, the cashier deposits the coins deposited by the customer into the coin slot 5.
Since there is almost no possibility that false coins will be thrown in, the 5-yen coin and 100-yen coin, which have a very small size difference, may be erroneously selected by the coin selection holes 27-1 to 27-6. high. Therefore, also in the first and second embodiments, the coin material sensor 29 is provided only below the coin selection hole 27-3 corresponding to the 5-yen coin and the coin selection hole 27-4 corresponding to the 100-yen coin. If the material of the coin that is provided and dropped is detected and the material of the coin detected from the coin selection hole 27-3 is white copper instead of brass, and if the material of the coin detected from the coin selection hole 27-4 is not white copper. If it is brass, it may be determined that each is erroneously selected. Since the coin material sensor is more complicated and more expensive than a sensor that optically detects the passage of coins, by doing so, the configuration can be simplified and the cost can be reduced. Even in this case, the remaining coin selection holes 27-1, 27-2, 27-
It goes without saying that it is necessary to provide a sensor for optically detecting the passage of coins on the lower side of 5, 27-6 to count the number of stored coins.

Further, in the second embodiment, the coin storage unit 1
The coin material sensor 29 detects the material of the coins stored in 2, and stores information on whether or not the material matches the material of the coin to be selected in the corresponding coin selection hole, the coin memory 80.
The coin material sensor 29 detects the coin dispensed from the coin storage unit 12, that is, the material of the leading coin of each coin row. However, when the coin does not match the material of the coin to be stored in the coin storing portion 12, the coin may be discharged to the coin receiving container 31 side to obtain the same effect as that of the present invention. By doing so, the stored coin memory 80 can be eliminated. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0060]

As described above in detail, according to the present invention, when the material of the coin selected by the size does not match the preset material of the coin, it is recognized that the coin is erroneously selected,
Since the change-out of coins is prohibited, it is possible to prevent an incorrect change-out amount from being paid out as much as possible, and it is possible to improve reliability.
