Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card withdrawal recording device in a game arcade system using a prepaid card on which an ID number is recorded.

[0002]

2. Description of the Related Art Conventionally, in a card system in a pachinko parlor, for example, a customer purchases a prepaid card in advance, and the customer inserts the card into a ball lending machine installed beside the pachinko machine using the card, and Buttons (generally,
When the user presses the pachinko machine once, a predetermined amount of money, for example, 300 yen (depending on the store). There is also a ball lending machine of a type that can be freely set by the customer. ) Ball comes out on the pachinko machine. You can borrow the ball with the ball lending button until the remaining balance of the card is exhausted, and if you want to stop on the way, press the card return button (also provided on the pachinko machine), the balance will be recorded and the card will be returned It has become. The amount of this prepaid card is 10,000 yen, 5000 yen, 3 yen
The ones such as 000 yen and 1000 yen are common.

[0003] However, while this card system is designed to be convenient for customers by having a prepaid card at any store, it has become a major social problem because card forgery is rampant.

Further, a card system for preventing this has been proposed. For example, as in a system disclosed in Japanese Patent Application Laid-Open No. 61-143085, an ID number is taken for each card to prevent forgery. In this system, when a new card is issued,
A request for registration of the D number is made, and after the card issuing machine receives the result from the computer at the shop, the ID is given to the card.
Printing of data including numbers and recording of magnetic data are performed. When a predetermined amount of balls are withdrawn from the card, the computer checks the balance with the computer at the store, but one withdrawal is limited to one time. Recently, a single withdrawal has become unsatisfactory at one time, and a single withdrawal is, for example, five times, that is, five.
It has begun to throw balls for 00 yen.

[0005]

However, in the above system, if there is a single withdrawal request and the remaining number of times is 5 or more (for 500 yen), the number of 5 is subtracted and then the ball is thrown out. Yes, if a ball breaks during the throwing of a ball, etc., the subtraction has already been completed, but the payout of the ball has not been completed to the customer, and it is extremely difficult for the attendant to handle the error Has become a problem. Therefore, if there is a remaining number at the time of the withdrawal request, it is better to issue a ball throwing command before the subtraction and to subtract when the throwing of the ball is completed. Is easy. However, in such a case, if the ball is illegally jammed by the customer before the throwing of the ball is completed and the card is pulled out, no deduction is made at all, and the remaining amount before the deduction is used by using this card. Assuming that there is a frequency, there is a problem that it is possible to draw out the ball for the remaining frequency again from another ball rental machine.

The present invention has been made in view of the above circumstances, and when a card is illegally removed, the removal is recorded as error information in a store computer.
It is an object of the present invention to provide a card pull-out recording device that updates and records the amount of money that has been thrown out halfway.

[0007]

In order to achieve the above object, according to the apparatus of the present invention, when a card is pulled out, the balance and error information at that time are transmitted to the terminal controller, and the terminal controller pulls out the card. It is characterized by recording.

That is, in the present invention, the usage status of prepaid cards, all of which have different ID numbers for each card, is stored, and when a prepaid card issuing machine requests registration of an ID number, it is determined whether or not the registration is possible. And a card reader / writer provided for each gaming machine for reading the prepaid card and writing information, and transmits read data to the terminal controller when a card is inserted into the card reader / writer. And a card unit that transmits an updated amount to the terminal controller based on the ejection of the game medium, wherein the card unit includes a prepaid card withdrawal detecting unit, and the prepaid card is detected by the withdrawal detecting unit. Pull-out detected To come, and transmits the balance and withdrawal errors at that time to the terminal controller, in the terminal controller, it is characterized in that so as to record in response to this withdrawal error ID number of the prepaid card.

Preferably, the terminal controller is provided with a pull-out recording file for recording the ID number having the pull-out error as an independent file.

According to the present invention, at the time when the removal is detected, the terminal controller detects that there is a removal error and the balance data at that time,
No cheating can be done and no damage occurs. It is still more effective if the terminal controller detects the occurrence of the pull-out error and instructs the data ball discharging unit to stop discharging.

Normally, when a card is inserted, a "processing flag" 1 is recorded on the card, and a "processing flag" 0 is written when the card is normally returned. There is no problem with inserting the card into the rental machine, but it is possible to abuse it and destroy the magnetism so that the magnetic record on the card cannot be read, and then ask the attendant to reissue the card. However, according to the apparatus of the present invention, if a ball is drawn out during lending, it can be reliably checked at the time of reissuance and fraud can be prevented.

[0012]

In the present invention, for example, the optical sensor B (s1, s2, s3, s4) of the card insertion section is monitored, and it is possible to detect that the card has been pulled out from the output of this optical sensor. In this manner, the balance and error information at that time are transmitted to the terminal controller, and the terminal controller records the withdrawal error in correspondence with the ID number of the prepaid card. In this manner, at the time when the removal is detected, the terminal controller detects that there is the remaining data and the removal error at that time,
If a ball is drawn out during lending, it can be checked reliably at the time of reissuance and fraud can be prevented.

[0013]

And a transport control section D for controlling transport of the card by R. S1 is a photosensor for detecting card insertion, S2 and S3 are photosensors for detecting various timings, and S4 is a photosensor for stopping card conveyance. These outputs are input to the CPU 70a to determine whether the card has been inserted or removed. And the like, and is input to the transport control unit D to control the transport of the card. The photo sensors S1 to S1
The removal of the card is detected using part or all of S4. The CPU 70a of the card unit 70 and the ROM 7
0b, the RAM 70c, and the optical sensor B correspond to a pull-out detection unit.

Next, the operation of the apparatus according to the embodiment of the present invention will be described. First, as shown in the explanatory view of FIG. 9, when card insertion and card lending are performed in the card unit 70, the card data processing is performed by the terminal controller 10 via the island controller 40 based on a request from the card unit, as shown in FIG. A process is performed in which the consistency of the card is checked and subtracted, and the result is returned. First, when a card is inserted in the card unit 70, a card check is performed on the island controller 40, the island controller performs polling processing, blocks data for a plurality of units, and performs a card check on the terminal controller 10. Then, the terminal controller checks whether the data corresponding to the requested card exists, and if so, whether the initial frequency of the card, the current frequency does not exceed the registered data recorded in the terminal controller, and whether the card is not a withdrawn card. . If the check is OK,
The result is sent to the island controller 40. Then, the island controller 40 passes the check result from the terminal controller to the card unit 70. Then, if the ball lending button is pressed and the ball lending is made, after subtracting by the card unit, a subtraction request is issued to update the balance,
Checked by the terminal controller, and if it is OK, the data of the card in the terminal controller is rewritten to the updated frequency, and OK is sent to the island controller.
On the other hand, at this time, when the card is illegally removed, the timing sensors of the optical sensor B, for example, s2 and s3 detect this. Then, an error request is issued to the island controller 40 via the CPU 70a, the error request is transmitted from the island controller 40 to the terminal controller 10, and recording is performed. Further, if the card unit receives the OK signal, the remaining amount at the time of removal is transmitted in the same manner, and if the OK signal recorded by the terminal controller is returned, the process ends. For example, when the removed card is inserted again into the card insertion slot of the card unit, a card check request is issued to the island controller 40, and the island controller issues a card check request to the terminal controller 10. Then, the terminal controller checks whether the data corresponding to the requested card exists, and if so, whether the initial frequency of the card, the current frequency does not exceed the registered data recorded in the terminal controller, and whether the card is not a withdrawn card. . Similarly, the check result is sent to the island controller 40, and the island controller 40 passes the check result from the terminal controller to the card unit 70. In the case of a check NG, the card is returned, or the error is displayed and an alarm is given while the card is taken in. To inform. If the check is OK, the ball lending button is pressed and the ball lending is executed, and the operation is continued while preventing fraud. In addition,
In this example, the error request and the subtraction request are transmitted separately, but if there is a pull-out error, the remaining amount at that time may be transmitted at a time. On the other hand, when the card return button is pressed in a state where the card has not been pulled out and the card has been inserted normally, similarly to the case of the ball lending button, a subtraction request is made, and the process ends normally if an OK signal is received.

Next, these processes will be described in detail with reference to flowcharts. FIG. 10 is a flowchart showing an operation in using the prepaid card according to the present invention. When the operation is started (step 101) and a prepaid card is inserted into the reader / writer 70d (step 102), the card is read (step 10).
3) The store number data and the like are checked to see if there is a remaining amount of the prepaid card (step 104). If there is a store number error or there is no remaining amount, the card is returned (step 105). In some cases, the error may be reduced while the card is taken in.

If there is a remaining number without a store number error,
When the lending frequency display and the balance display are performed (step 106), an inquiry is made to the terminal controller 10 and a card check is performed by the terminal controller (step 107).

If it is determined that the card is fraudulent,
An error occurs with the card taken in (step 108), and the clerk waits for processing. On the other hand, if it is determined by the card check that the operation is appropriate, the operation waits (step 109). Note that the buttons cannot be used up to this point, but at this point, the amount setting button is pressed (step 110), the fraction display button is pressed (step 111), and the lending button is pressed (step 11).
2), the return button can be pressed (step 113).

When the rental button is pressed (step 112), as shown in FIG.
A pachinko ball throwing signal is output to the lending ball throwing unit of the gaming machine (step 201). In addition, the ball is automatically thrown out for the amount of 100 yen once, and the remaining amount is thrown out if the ball is out of the way while throwing out the ball for 100 yen if it is replenished.
When the throwing of a predetermined amount of balls is completed, a completion signal is sent from the ball throwing unit. Only when the completion signal is obtained, the remaining balance is transmitted to the terminal controller.

By the way, at the time before the transmission, the prepaid card is pulled out, and it is determined whether or not the card is detected by the optical sensor B of the reader / writer 70d (step 202). Then, after an error display (Step 203), a command to stop throwing out to the ball throwing unit (Step 204), and creation of error data (Step 205), a correct remaining balance at that time is calculated ( Step 206), the balance is displayed (step 207).

Then, an error request is made by sending the card ID, the error data and the subtracted amount data to the terminal controller (step 208). Then, the result is received by echo back from the terminal controller 10 (step 209), and it is determined whether or not it is OK (step 210), and if NG, the error is reduced (step 211). If it is OK, it is on standby (step 212). When an error request is made, a pull-out error is stored in the memory of the terminal controller corresponding to the ID number. Alternatively, the card ID number is stored in a file containing only the extraction error.

On the other hand, if it is determined in the determination step 202 that the card has not been removed, the remaining amount is calculated (step 213) and the balance is subtracted (step 214).
Is performed, and a subtraction request is made by sending the card ID and the subtracted amount data to the terminal controller (step 215). Then, the result is received by echo back from the terminal controller (step 21).
6), it is determined whether or not it is OK (step 21)
7) If NG, error down (step 211). If it is OK, it is determined whether or not it is the first lending (step 218). If it is not the first lending, the card processing flag is already written on the card. The card processing flag is written (step 219), for example, the number of game media (lending balls / medals) corresponding to 200 yen, which is two withdrawals.
It is supplied to the saucer. It is determined whether there is a card balance (step 220). If there is a balance, the operation is waiting (step 222). This state is similar to the operation waiting state 109 shown in FIG. 10, and thereafter, every time the lending button is pressed, a number of game media (lending balls / medals) corresponding to the same withdrawal frequency are supplied to the receiving tray. . In addition to pressing the lend button (step 112), the user can press the amount setting button again (step 110), press the fraction display button (step 111), and press the return button (step 113). Here step 220
In the card balance determination step, if the fractional amount is, for example, 50 yen, the player cannot supply the game medium because the amount is less than the withdrawal unit frequency of 100 yen even if the lending button is pressed. In this case, that is, when the remaining number of cards is less than the minimum unit (one time) of the withdrawal frequency, it is necessary to use a new prepaid card.

On the other hand, if the remaining amount in the prepaid card becomes 0 without any fraction, the prepaid card is returned from the card insertion slot (step 221). Alternatively, it can be collected by a collection path (not shown) via a card reader / writer. If there is no card balance in this way, a return process is performed.

When the balance frequency in the prepaid card becomes smaller than the withdrawal frequency during the supply of the game media, when the lending command button 112 is pressed, the remaining number of game media is released. Supplied. For example, when the set frequency is 3 and the price is 300 yen, the game medium for 200 yen is supplied even if only the frequency of 2 times remains. When the dispensing of the loaned ball is completed, the remaining number is automatically displayed on the display unit.
When the throwing is completed and the remaining number of cards becomes 0, the card is automatically returned.

When the user wants to return the card while waiting for the operation in the flowchart of FIG. 10, the return button is pressed.

Further, on the terminal controller side, FIG.
As shown in FIG. 2, when the terminal controller is in the standby state (step 401), it is determined whether or not there is a card balance subtraction request from the card unit (step 40).
2) When there is no subtraction request, it is determined whether an error request has been made from the card unit (step 40).
3). If it is determined in this determination step that there is no error request, it is determined whether or not an inquiry has been made from the card unit (step 404).
When an inquiry is made, the contents of the card are compared with the contents stored in the terminal controller (step 40).
5) It is determined whether or not the two contents match (step 406). If they do not match, an NG signal is transmitted (step 408). If they match, an OK signal is transmitted (step 406). 407). Then, it is on standby.

In step 402, it is determined whether or not there is a card balance subtraction request. If there is a subtraction request, the contents of the card are compared with the contents stored in the terminal controller as shown in FIG. Step 40
9) It is determined whether or not the two contents match (step 410), and if they do not match, an NG signal is transmitted (step 411). If they match, the remaining amount managed for each card ID is subtracted (step 412), and it is determined whether or not this subtraction processing is OK (step 413). And NG if NG
A signal is transmitted (step 414), and if OK, OK
A signal is transmitted (step 415) and the card data update is saved (step 416).

Further, if it is determined in step 403 in FIG. 12 that there is an error request, the terminal controller T / C 10 records that a pull-out error has occurred (step 403). Step 417), the fact that the error has been confirmed is transmitted to the card unit 70 via the island controller 40 (step 418). Then, it is on standby. If it is determined in step 404 whether or not there is an inquiry from the card unit, the flow returns to step 402 to determine whether or not there is a card balance subtraction request.

Next, when a card which has been pulled out in the middle as described above is inserted into the card unit thus set, the card is first inserted in the same manner as in the first card insertion shown in FIG. Is determined (step 102), and when it is determined that the card has been inserted, the magnetic data written on the card is read using the magnetic head A of the reader / writer 70d (step 102). 103). Then, this data is sent to the terminal controller to make an inquiry. At this time,
The terminal controller compares the data with the data stored in the withdrawal record file, and when it is detected that the card is a withdrawal card, displays an error and sets an error down.
Further, the card reader / writer may rewrite the balance data based on the balance data of the terminal controller without displaying an error, and the lending of the ball may be continued based on the data.

That is, the contents of the card are compared with the contents stored in the terminal controller. If the balance of the card is larger than the balance stored in the terminal controller, the card reader / writer determines the balance data based on the balance data of the terminal controller. Is rewritten and ball lending is continued.

On the other hand, by making it impossible to read magnetic data,
If you ask the staff to reissue, you can easily detect the remaining amount by inquiring the terminal controller,
An accurate balance can be detected. Also, in FIG. 11, the float is detected only after the lending button is pressed, but in reality, after the card is inserted, the card is always monitored for being removed, and the removal is detected. At this point, it is transmitted to the terminal controller by an interrupt signal.

In the above embodiment, the pachinko ball lending machine has been described, but the present invention may be applied to a slot machine medal lending machine. The processing flag 1 is recorded on the card when it is inserted into the unit, but this recording need not be recorded. Although the balance is printed and recorded again on the card when the return operation is performed normally, a system in which the balance is not printed on the card at all may be used.

Further, in the embodiment, the card is printed and magnetically recorded each time using a roll of paper, cut and temporarily held, but it may be printed and magnetically recorded on a card cut in advance. Alternatively, a card in which only the amount of money is printed in advance may be stored for each amount of money, and only the magnetic data may be recorded on the card.

In the present invention, the ball is thrown from the gaming table, but a ball lending machine in which the card unit and the ball throwing unit are integrated or a medal in which the card unit and the medal throwing unit are integrated. A rental machine may be used.

[0042]

As described above, according to the apparatus of the present invention, if a ball is pulled out during lending, it can be reliably checked at the time of reissuance and fraud can be prevented.
Further, at the time when the extraction is detected, the terminal controller detects the remaining amount data at that time and the fact that the extraction error has occurred, so that damage can be prevented.
