BACKGROUND OF THE INVENTION
The present invention provides a game hall system using a prepaid card in which an ID number is recorded. In particular, a game system that effectively prevents damage caused by unauthorized withdrawal of cards. Related.
[0002]
[Prior 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 and uses a ball lending button (generally , Provided on the pachinko machine) once, for a preset amount of money, for example 300 yen (depending on the store. There are also ball lending machines that customers can set freely. ) Comes out on the top plate of the pachinko machine. You can borrow a ball with the ball lending button until the remaining amount of the card runs out, and if you want to stop halfway, press the card return button (also provided on the pachinko machine) and the remaining amount will be recorded and the card will be returned It is like that. The amount of this prepaid card is generally 10,000 yen, 5000 yen, 3000 yen, 1000 yen or the like.
[0003]
However, this card system has been a major social problem due to the prevalence of card counterfeiting, while prepaid cards can be used in any store for the convenience of customers.
[0004]
A card system that prevents this has also been proposed. For example, as in the system disclosed in Japanese Patent Laid-Open No. 61-143085, there is a system that takes an ID number for each card to prevent forgery. In this system, when a card is newly issued, an ID number registration request is made to the store computer, and after the result is received by the card issuer from the store computer, data including the ID number is printed on the card. In addition, recording of magnetic data is performed. Further, when a predetermined amount of balls is withdrawn from the card, the remaining amount is confirmed on the store computer, but one withdrawal is limited to one time. Recently, a single drawer has become unsatisfactory with a single number of drawers, and a single drawer has for example thrown a ball of 5 degrees, or 500 yen.
[0005]
[Problems to be solved by the invention]
However, in the above system, if there is a withdrawal request once and the remaining frequency is 5 times (500 yen) or more, the ball is allowed to be thrown after subtracting 5 times, and the ball is thrown. If a ball breaks off in the middle, the subtraction has already been completed, but the ball has not been paid out to the customer, and there is a problem that error handling by the staff becomes extremely difficult. Therefore, if there is a remaining number when a withdrawal request is made, it is better to issue a ball throwing command before subtraction and subtract it when the ball has been thrown away. Is easy. However, if this is done, the customer will be clogged illegally before the ball has been thrown out, and if the card is pulled out, no subtraction will be done. There was a problem that it was possible to withdraw the remaining number of balls again from another ball lending machine because of the frequency.
[0006]
Therefore, The present invention A game in which damage can be effectively prevented even if the card is pulled out illegally, such as when the game medium is illegally jammed by the customer before the game medium is completely thrown out. system The purpose is to provide.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the device of the present invention, when the card is pulled out, the remaining amount and error information at that time are transmitted to the terminal controller, and the withdrawal is recorded by the terminal controller. To do.
[0008]
That is, in the present invention, a terminal controller that stores the usage status of prepaid cards with different ID numbers for each card and determines whether or not registration is possible when a prepaid card issuing machine requests registration of an ID number. And a card reader / writer that is provided corresponding to each gaming machine and reads data recorded on the prepaid card from the prepaid card and writes data to the prepaid card, and the card is inserted into the card reader / writer A card unit that transmits read data to the terminal controller, and transmits the updated amount of the prepaid card to the terminal controller upon completion of throwing out the game medium to the gaming machine based on the read data of the prepaid card. The terminator The controller manages the remaining amount of the prepaid card transmitted from the card unit in correspondence with an ID number corresponding to the prepaid card, wherein the card unit is in the middle of throwing out the game medium Prepaid card withdrawal detection means for detecting withdrawal of the prepaid card, and when the withdrawal of the prepaid card is detected by the prepaid card withdrawal detection means, the remaining amount of the prepaid card at that time And when the withdrawal of the prepaid card is detected by the prepaid card withdrawal detection means, the remaining amount of the prepaid card calculated by the computation means and the And a transmission means for transmitting to the terminal controller an extraction error indicating that the prepaid card has been illegally extracted. Is And recording the withdrawal error transmitted by the transmission means in correspondence with the ID number of the prepaid card With recording means It is characterized by that.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, for example, the optical sensor B (s1, s2, s3, s4) of the card insertion portion is monitored so that it can be detected that the card has been pulled out from the output of this optical sensor. The balance and error information are transmitted to the terminal controller, and the terminal controller records the withdrawal error corresponding to the ID number of the prepaid card.
In this way, when a withdrawal is detected, the terminal controller detects that there is a withdrawal error with the remaining amount data at that time, and if there is a withdrawal during the ball lending, it will be reissued Sometimes it can be checked reliably and fraud can be prevented.
[0013]

[0019]
The card unit 70 also receives the ball purchase amount information from the gaming table 60, calculates and stores the balance, transmits the balance information to the gaming table 60, and outputs the ball purchase amount information to the island controller 40. It is supposed to be. Here, between the island controller 40 and the card unit 70, for example, two transmission lines are used to send signals in an inverted relationship with each other, and a transmission / reception method in which data reliability is improved is adopted.
[0020]
FIG. 7 is a block diagram showing the control system of the card unit 70. The control system of the card unit 70 includes a CPU 70a that performs arithmetic processing, a ROM 70b that stores programs, control data, and the like, a RAM 70c that stores program data of operating states, and a prepaid card reader that reads and writes recorded information on prepaid cards.

These outputs are input to the CPU 70a, and whether or not the card is inserted or not And the like are input to the conveyance control unit D to carry out card conveyance control. Card withdrawal is detected using part or all of the photosensors S1 to S4. Note that the CPU 70a, ROM 70b, RAM 70c, and optical sensor B of the card unit 70 correspond to an extraction detection unit.
[0022]
Next, the operation of the apparatus according to the embodiment of the present invention will be described.
First, as shown in the explanatory diagram of FIG. 9, the card data is processed by the terminal controller 10 via the island controller 40 based on the request of the card unit 70 when the card unit 70 inserts and lends the ball. A process of checking and subtracting the card consistency and returning the result is performed. 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 a polling process to block 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 there is, the initial frequency and the current frequency of the card do not exceed the registered data recorded in the terminal controller, and further check whether it is not a withdrawal 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. When the ball lending button is pressed and the ball lending is made, after subtracting with the card unit, a subtraction request is issued to update the remaining amount, the terminal controller checks and if OK, the data of the card in the terminal controller is updated. Later, the frequency is rewritten and OK is sent to the island controller. On the other hand, when the card is illegally pulled out, the timing sensor of the optical sensor B, for example, s2 and s3 detects this. Then, an error request is issued to the island controller 40 via the CPU 70a, and the error request is transmitted from the island controller 40 to the terminal controller 10 for recording. Further, when the card unit receives an OK signal, the remaining amount at the time of withdrawal is transmitted in the same manner, and the process ends when the terminal controller records the OK signal. For example, when the drawn card is inserted again into the card insertion slot of the card unit later, a card check request is made to the island controller 40, and the island controller makes 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 there is, the initial frequency and the current frequency of the card do not exceed the registered data recorded in the terminal controller, and further check whether it is not a withdrawal 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 check NG, the card is returned or an error display and an alarm are given while being taken in. To inform. If the check is OK, the ball lending button is pressed and the ball lending is executed, and so on. The operation is continued while preventing fraud. In this example, the error request and the subtraction request are transmitted separately, but if there is a withdrawal error, the remaining amount at that time may be transmitted at once.
On the other hand, when the card return button is pressed in a state where the card return button is normally inserted without being pulled out, a subtraction request is made in the same manner as in the case of the ball lending button, and if the OK signal is received, the process ends normally.
[0023]
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 103), and the store number data is checked to see if there is a remaining amount of the prepaid card ( 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 with the card taken in.
[0024]
If there is a remaining amount without a store number error, the lending frequency and balance are displayed (step 106), the terminal controller 10 is inquired, and the card check is performed by the terminal controller (step 107).
[0025]
If it is determined that the card is a fraudulent card, the error is reduced with the card being taken in (step 108), and the process waits for the store clerk.
On the other hand, if it is determined that the card check is appropriate, the operation waits (step 109). The buttons cannot be used until this point, but for the first time at this point, the amount setting button is pressed (step 110), the fraction display button is pressed (step 111), the lending button is pressed (step 112), and the return button is pressed. It can be pressed (step 113).
[0026]
If the lending button is pressed (step 112), a pachinko ball throwing signal is output to the lending ball throwing unit of the gaming machine as shown in FIG. 11 (step 201). The balls are automatically thrown out for several hundred yen once, and if the ball runs out during throwing out the 100 yen ball, the remaining part is thrown out. When the throwing of a predetermined amount of balls is completed, a completion signal is sent from the ball throwing unit. Only after this completion signal is obtained, the renewal balance is transmitted to the terminal controller.
[0027]
By the way, at the time before this 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), and it is determined that the card has been pulled out. After the error display (step 203), the throwing stop command to the ball throwing unit (step 204), and the creation of error data (step 205), the correct renewal balance at that time is calculated (step 206). The balance is displayed (step 207).
[0028]
Then, an error request is made by sending the card ID, error data, and subtracted amount data to the terminal controller (step 208). Then, the result is received by echo back from the terminal controller 10 (step 209), it is determined whether or not it is OK (step 210), and if it is NG, the error is reduced (step 211). And if it is OK, it will be on standby (step 212). When there is an error request, an extraction 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 with only a withdrawal error.
[0029]
On the other hand, if it is determined in step 202 that the card has not been withdrawn, the remaining amount is calculated (step 213) and the balance is subtracted (step 214), and the card ID and the amount data after subtraction are displayed on the terminal controller. By sending, a subtraction request is made (step 215). Then, the result is received by echo back from the terminal controller (step 216), it is determined whether or not it is OK (step 217), and if it is NG, the error is reduced (step 211). Then, if it is OK, it is determined whether or not it is the first lending (step 218). If it is not the first time, a card processing flag is already written on the card. A card processing flag is written (step 219), and for example, a number of game media (rented balls / medals) corresponding to 200 yen, which is a two-time withdrawal, is supplied to the tray. It is determined whether there is a card balance (step 220). If there is a balance, it is waiting for an operation (step 222). This state is the same as the operation waiting state 109 shown in FIG. 10, and thereafter, every time the rental button is pressed, the same number of game media (rental balls / medals) corresponding to the same number of withdrawals are supplied to the tray. . In addition to pressing the lending button (step 112), the money amount setting button can be pressed again (step 110), the fraction display button can be pressed (step 111), and the return button can be pressed (step 113). Here, in the card balance determination step of step 220, if the fractional amount is 50 yen, for example, even if the player pushes the lending button, the player cannot supply the game medium because the amount is less than the withdrawal unit frequency of 100 yen. In this case, that is, when the remaining card number is less than the minimum unit (one degree) of the withdrawal frequency, it is necessary to use a new prepaid card.
[0030]
On the other hand, when the balance in the prepaid card becomes 0 without any fraction, the prepaid card is returned from the card insertion slot (step 221). Or it can also collect | recover by the collection | recovery path | route which is not illustrated via a card reader / writer.
If there is no card balance in this way, return processing is performed.
[0031]
Further, when the balance frequency in the prepaid card becomes smaller than the withdrawal frequency during the supply of game media, when the lending command button 112 is pressed, game media for the remaining frequency is supplied. . For example, when the set frequency is 3 and is 300 yen, even if only 2 times remain, game media for 200 yen is supplied. When the lending is finished, the remaining number is automatically displayed on the display unit. When the card is thrown out and the remaining card count becomes 0, the card is automatically returned.
[0032]
When the user wants to return the card in the operation waiting state in the flowchart of FIG. 10, the return button is pressed.
[0033]
Further, on the terminal controller side, as shown in FIG. 12, when the terminal controller is in a standby state (step 401), it is determined whether or not there is a card balance subtraction request from the card unit (step 402). Determines whether an error request is made from the card unit (step 403). If it is determined in this determination step that there is no error request, it is determined whether or not there is an inquiry from the card unit (step 404). When an inquiry is made, the contents of the card and the stored contents of the terminal controller are collated (step 405), and it is determined whether or not the contents of the two match (step 406). Is transmitted (step 408), and if they match, an OK signal is transmitted (step 407). And it will be waiting.
[0034]
In step 402, it is determined whether or not there is a card balance subtraction request. When there is a subtraction request, the contents of the card are compared with the stored contents of the terminal controller as shown in FIG. 13 (step 409). Then, a determination is made as to whether or not the contents match (step 410). 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 the subtraction process is OK (step 413). If it is NG, an NG signal is transmitted (step 414). If it is OK, an OK signal is transmitted (step 415), and the card data update is stored (step 416).
[0035]
Furthermore, if it is determined in step 403 for determining whether or not an error request has been made in FIG. 12, the terminal controller T / C 10 records that there has been an extraction error (step 417). The fact that the error has been confirmed is transmitted to the card unit 70 via the island controller 40 (step 418). And it will be waiting. If it is determined in step 404 whether or not there is an inquiry from the card unit, the process returns to the step of determining whether or not there is a card balance subtraction request in step 402 again.
[0036]
Next, when a card that has been pulled out 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. If it is determined that the card has been inserted (step 102), the magnetic data written on the card is read using the magnetic head A of the reader / writer 70d (step 103). This data is sent to the terminal controller to make an inquiry. At this time, the terminal controller checks the data stored in the drawing record file, and if it is detected that the card is a drawing card, an error is displayed and the error is reduced. 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 ball lending may be continued based on this data.
[0037]
That is, the contents of the card and the stored contents of the terminal controller are collated. When the remaining amount of the card is larger than the remaining amount stored in the terminal controller, the card reader / writer rewrites the balance data based on the balance data of the terminal controller. And continue lending.
[0038]
On the other hand, when the magnetic data cannot be read and the staff is requested to reissue, the remaining amount can be easily detected by making an inquiry to the terminal controller, and the accurate remaining amount can be detected. Further, in FIG. 11, the flow for detecting the withdrawal only after the lending button is pressed. When However, in practice, after the card is inserted, the card is always monitored for removal, and when the removal is detected, an interrupt signal is sent to the terminal controller.
[0039]
In the above-described embodiment, the pachinko ball lending machine has been described. However, the present invention may be applied to a slot machine medal lending machine. Further, the processing flag 1 is recorded on the card when it is inserted into the unit, but this recording need not be performed. Further, when the return operation is normally performed, the remaining amount is printed and recorded again on the card. However, a system in which the remaining amount is not printed and recorded on the card may be used.
[0040]
In the embodiment, the card is a roll paper, and is printed / magnetically recorded and cut and temporarily held each time. However, the card may be printed / magnetically recorded on the card that has been cut in advance. Alternatively, a card on which only the amount is printed in advance may be stored for each amount, and only magnetic data may be recorded on the card.
[0041]
Further, in the present invention, the ball throwing is performed from the game stand, but the ball lending machine in which the card unit and the ball throwing part are integrated or the medal lending machine in which the card unit and the medal throwing part are integrated. But you can.
[0042]
【The invention's effect】
As described above, according to the apparatus of the present invention, when there is a withdrawal in the middle of lending the ball, it can be surely checked at the time of reissuance, fraud can be prevented, and when the withdrawal is detected Since the terminal controller detects the remaining amount data at that time and that there was a withdrawal error, damage can be prevented.
