Abstract

PURPOSE:To surely use up the coins stored in a coin store part by switching the types of coins which are discharged based on the discharging states of coins. CONSTITUTION:A coin processor 11 is provided with the coin store parts 1a - 1d for Yen500, Yen100, Yen50, and Yen10 coins respectively. The types of coins supplied through a coin slot 3 are identified by a money type identifying part 4, and the identified coins are stored in the parts 1a - 1d respectively through a distribution processing part 5. Then the coins are discharged out of the parts 1a - 1d and sent to a coin discharging part 6 in number corresponding to the number of discharge signals. If the discharge of coins are not detected within a fixed time after the discharge signal is inputted to a certain coin store part, the coins equivalent to the corresponding amount are discharged from another coin store part storing the coins of a lower type of money. As a result, the coins stored in a coin store part can be surely used up.

Description

DETAILED DESCRIPTION OF THE INVENTION ta) Industrial Field of Application The present invention relates to a coin processing device for processing coins deposited and withdrawn in a device such as an ATM'M (Automated Transaction Processing Machine).

(b) Prior Art A coin processing device included in an ATM or other device includes a coin storage section for each denomination, and releases a required number of coins from each coin storage section in accordance with a release signal based on a request for change. However, the number of coins that can be stored in the coin storage section is limited, and if the required number of coins is not in the coin storage section for coin discharging processing, a coin of a lower denomination must be substituted, or the processing operation must be stopped. Must be. Therefore, conventional coin processing devices are equipped with a detection means for detecting whether a predetermined number or more of coins are stored in each coin storage section. In such cases, the release of coins of that denomination was stopped to encourage replenishment.

(C) Problem to be Solved by the Invention However, if the conventional coin processing device described above is configured to stop discharging coins when the number of coins stored in the coin storage section falls below a certain amount, the coin storage section As a result, the number of coins that make up the change increases and the work to replenish coins becomes more frequent. ), which caused the problem that the operating efficiency of the equipment decreased.

The purpose of this invention is to enable the coin ejecting operation to be continued until the coins can no longer be ejected from the coin storage section, to enable all the coins stored in the coin storage section to be ejected, and to increase the number of coins. An object of the present invention is to provide a coin processing device that can prevent frequent coin replenishment work and improve operating efficiency.

(Means for Solving Problem d1) The coin processing device of the present invention includes a plurality of coin storage sections that store coins for each denomination and release coins by inputting a release signal, and a coin processing device that stores coins for each denomination and releases coins from each coin storage section. and a coin processing device, wherein the release detection means does not detect the release of a coin within a predetermined time after a release signal is input to one coin storage section. In this case, the present invention is characterized in that a denomination switching means is provided for discharging coins of a corresponding amount from a coin storage section of a lower denomination than the coin storage section.

(e) Function The function of the present invention will be explained below with reference to FIG. The denomination switching means outputs a release signal to the coin storage section of the denomination corresponding to the change request, and coins are ejected from the coin storage section. The discharge state of coins from the coin storage section is detected by the discharge detection means, and the output of the discharge detection means is inputted to the denomination switching means.

Even though the denomination switching means outputs a discharge signal to the coin storage section a storing coins of a high denomination, if the discharge detection signal of the discharge detection means a of the denomination is not input, A release signal is output to the coin storage section storing coins of lower denominations.

('') Embodiment FIG. 2 is a schematic diagram showing the configuration of a coin processing device that is an embodiment of the present invention.

The coin processing device 11 includes coin storage sections 1a to 1d for each denomination of 500 yen, 100 yen, 50 yen, and 10 yen. After the coins inserted into the coin slot 3 of a device such as an ATV are identified by the denomination identification unit 4, they are transferred from the sorting unit 5 to the coin storage units 1a-1d for each denomination. stored. Further, the number of coins corresponding to the ejection signal is ejected from each coin storage section 1a-1d to the coin ejection section 6.

FIG. 3 is a schematic diagram showing the configuration of a coin storage section provided in the coin processing device.

Coins are inserted into the coin storage section 1 from above. A coin ejecting device 2 is provided on the bottom surface inside the coin storage section 1, and a driver D is provided below the coin ejecting device 2. The driver D is driven by a discharge signal outputted from a control section, which will be described later, and discharges the coins stored in the coin storage section 1 one by one.

A storage detection sensor S1 consisting of a light emitting element and a light receiving element is provided in the vertically intermediate portion of the coin storage section 1. This storage detection sensor S1 detects the storage state of coins in the coin storage section l. Further, a release detection sensor S2 is provided near the release lower of the coin storage section 1. This discharge detection sensor S2 detects whether a coin is discharged from each coin storage section 1 or not.

FIG. 4 is a block diagram of the control section of the coin processing device.

A program that defines the processing procedure of the CPU 41 is written in advance in the ROM 42 connected to the CPU 41.
The CPU 41 executes processing operations according to this program. The CPU 41 is connected via the I10 interface 44 to the storage detection sensors Sla to Sld that the coin storage units 1a to ld have, and the release detection sensors 52a to 52a.
Detection data of 32d is input. Further, a change request signal is input from a control unit of a main device such as an ATM equipped with a coin processing device. The CPU 41 outputs discharge data to the driver D a % D d in accordance with the change request signal and the detection data of the sensors 5 la to 3 ld and 52 a to 32 d. At this time, the input/output data is temporarily stored in a predetermined memory area of the RAM 43. As shown in FIG. 5, memory areas MA1 to MA5 of the RAM 43 are allocated to counters Ca-Cd and timer T, respectively.

Counters Ca-Cd each have 500 yen and 109 yen.
The number of yen, 50 yen, and 10 yen coins released is stored.

FIGS. 6(A) and 6(B) are flowcharts showing the processing procedure of the control section of the coin processing device.

Upon input of the change request signal, the CPU 41 selects the denomination corresponding to the amount of change, and sets the number of coins to be released in the counter for each denomination. Now, if the amount of change requested is 60 yen, select a 50 yen coin or a 10 yen coin as the denomination of the coin to be released.
The number l is stored in each of counters Cc and Cd assigned to M A 3 and M A 4, respectively.
n2゜n3). Next, select the higher denomination (of the selected denominations).
Coin storage section (here, coin storage section I) of 50 yen)
The driver Dc of C) is driven (n4). At the same time, the timer T allocated to the memory area M A 5 of the RAM 43 is activated (n5). This timer T determines the time at which coins are to be ejected from the ejecting lower at 31 o'clock after the coin ejecting device 2 operates.

If the release detection sensor S2c detects the release of a coin before the timer T times up, the counter Cc is decremented (n6.n7-+n8). counter C
When the content of c becomes 0, the operation of the coin discharging device 2 is stopped (n9.n1O).

After that, the driver Dd of the coin storage section (in this case, the coin storage section ld) storing coins of the lower denomination among the selected denominations is driven (n21). At the same time, the above-mentioned timer T is started (n22), and if the release detection sensor S2d detects the release of a coin before the timer T times out, the counter Cd is decremented (n23).
．． n24→n25). When the content of the counter Cd becomes 0, driving of the driver Dd is stopped (n 26. n
27). Through the above processes n1 to nlO and n21 to n27, one 50 yen coin and one 10 yen coin are released.

Above n6. If the timer T times up before the release detection sensor S2c in which the coin storage section 1c containing the 50 yen coin exists detects the release of a coin at n7, the drive of the driver Dc is stopped.n7-nll), the storage detection sensor SIC Check the on/off status of (n12)
). When more than a certain number of coins are stored in the coin storage section 1, the storage detection sensor S1 turns off because the light from the light emitting element is blocked by the coins and does not reach the light receiving element. On the other hand, when the amount of coins stored in the coin storage section l falls below a certain number, the light from the light emitting element is received by the light receiving element and turns on.

Therefore, even though the storage detection sensor Slc is off at Ω12 and a sufficient number of coins are stored in the coin storage section 1c, if a 50 yen coin is not released within the predetermined time, It is determined that a coin jam has occurred, and the corresponding processing is executed (n14). Storage detection sensor 3
1 is on, it is determined that the number of coins stored in the coin storage section 1c has reached O, and the number of released 50 yen coins (contents of counter Cc) is set to 5 to the counter Cd that counts the number of released 10 yen coins. Add the multiplied value and proceed to n21 (r
113) - The above n12-n13-n21 are the processes of the denomination switching means shown in FIG. 1, and the change is replaced by a 10 yen coin instead of a 50 yen coin. Therefore, when proceeding to n21, the content of the counter Cd is 6, and n22~
The process n26 is performed six times in succession, and six 10 yen coins are ejected from the coin storage section 1d.

Note that if the timer T times up before the release detection sensor S2d detects the release of a coin in the coin storage section 1d that stores a 10 yen coin, the driver Dd is stopped and the storage detection sensor Sld is turned on/off. Check (n24-n28, n29). Storage detection sensor Sld
If it is off, do not perform coin jam processing.
31), if it is on, executes coin replenishment processing (n30). This is for the same reason as n12 to n14 described above, and the reason why the coin replenishment process is performed in n30 is because the 10 yen coin is the lowest denomination in this coin processing device 11.

As described above, according to this embodiment, when the number of coins stored in the coin storage section is below a certain amount and a coin is not ejected, a coin of a lower denomination is substituted and ejected. be able to. Therefore, the coins stored in the coin storage section can be reliably used up.

(g1 Effect of the invention According to this invention, the denomination of coins to be ejected can be switched based on the ejection state of the effect, the coins stored in the effect storage section can be reliably used up, and the amount of change can be reduced. By substituting coins of this denomination, it is possible to prevent an increase in the number of change, and also to prevent frequent coin replenishment work, which has the advantage of improving the operating efficiency of the device.
