BACKGROUND OF THE INVENTION
The present invention relates to a slot machine in which a plurality of symbol strings are displayed in a variable manner, and then the variable display of each symbol array is stopped in order, and the winning or losing is determined according to the combination of the symbols displayed in a stopped manner. The present invention relates to a slot machine having a function for dealing with an illegal act by a person or the like.
[0002]
[Prior art]
In pachinko halls, fraudulent acts (generally called “got”) against gaming machines such as pachinko machines and slot machines are regarded as problems. In particular, in slot machines, a medal hung with a thread from the medal slot (hereinafter referred to as a “thread-hanging medal”) is inserted and reciprocated to execute a game without inserting an actual medal, Unauthorized acts such as opening the door and exploiting medals in the hopper are conspicuous.
[0003]
In order to prevent such illegal acts, in conventional slot machines, sensors for detecting abnormalities are provided in various parts of the fuselage, and when an abnormality is detected by these sensors, an alarm is sounded or the type of abnormality that has occurred is specified. By displaying it, etc., the staff is promptly notified of the occurrence of fraud.
[0004]
[Problems to be solved by the invention]
However, since conventional slot machines use a waiting period during which no games are played to check whether any abnormalities have occurred, Cannot be detected, and there is a problem that fraud is overlooked.
For example, when a fraudulent act with a thread hanging medal is performed, if the medal is inserted and the movement in the normal direction is detected and then the start lever is operated and the reel is started and then the medal is pulled back, the medal is pulled back. It becomes impossible to detect, and the game proceeds as it is.
[0005]
  This invention was made paying attention to the above-mentioned problem, and even when an illegal act is performed during the game,, The abnormalities caused by that actReliable detectionAnd promptly handling the abnormalityThe purpose is to prevent damage from occurring.
[0006]
[Means for Solving the Problems]
  The slot machine according to the present invention isA gaming switch group including a plurality of symbol rows, a start lever and a plurality of stop button switches corresponding to each symbol row,The medal can be accepted and the game can be started.Of the start leverDepending on the operationSaidAfter variably displaying multiple symbol columns, each symbol column can be displayed in a variable manner.Of the corresponding stop button switchStops according to the operation, and when all symbol sequences stop, game control means for operating the medal payout mechanism in response to the combination of symbols for winning a prize being stopped and displayed, and detecting an abnormality occurring in the aircraft The apparatus includes an abnormality detection unit and an abnormality response unit that executes a predetermined response process when an abnormality is detected by the abnormality detection unit.
  The abnormality detection means includes an abnormality content determination means for determining whether or not the detected abnormality is an abnormality due to an illegal act on the aircraft, and during a normal process including a process by the game control means being executed An interrupt is generated every time, and abnormality detection and determination processing by the abnormality content determination means are executed.
  The abnormality handling means isThe abnormality content determination meansDisplays the details of the detected abnormality based on the judgment resultforNotification means;When abnormality is detected by the abnormality detection means, abnormality processing execution means for executing abnormality processing by setting a reception prohibition state in which all switch operations are not accepted and notification of abnormality contents by the notification means,When an abnormality is detected by the abnormality detection means during the symbol string variation display, and the abnormality content determination means determines that the abnormality is an abnormality due to an illegal act, the symbol string during the variation display does not stop. By setting, an abnormality is detected by the abnormality detection means during the display of the variation of the symbol string and the game stopping means for stopping the progress of the game, and the abnormality content determination means determines that the abnormality is an abnormality due to an illegal act. And when a medal payout is performed by the medal payout mechanism when the abnormality is detected, a payout operation stop means for forcibly stopping the payout of the medal, and an abnormality is detected by the abnormality detection means during the symbol string fluctuation display. And when the abnormality content determining means determines that the abnormality is due to a cause other than fraud,An abnormality that delays the execution of the abnormality processing by the abnormality processing execution means until the variation display of all the symbol strings being varied is stopped.Processing delay means.
[0007]
  "Game"The term “machine state” refers to the state of the machine during the period from the start of the variable display of each symbol column to the end of the variable display of all the symbol columns. When a winning is established, it can be considered as a gaming state until the payout of the medals for the award and the effect processing of the winning are completed.
[0008]
  CheatingIs determined to be abnormal due toFor example, abnormalities such as reciprocal movement of medals by the above-mentioned thread-suspended medals, unauthorized opening of front doors, unauthorized payment of game media, etc.It is. other than this,When a reel rotation or game media payout operation is executed, these operations are performed normally.It is desirable to determine that there is no abnormality due to an illegal act of causing the machine to malfunction by operating radio waves from the outside.
[0010]
  In the slot machine configured as described above, during normal processing, an interrupt is generated every predetermined time to detect various abnormalities, and when abnormalities are detected, the abnormalities are caused by fraudulent acts. Therefore, even if an illegal act is performed during the game, this can be detected immediately. AlsoIf an abnormality due to fraud is detected, it becomes impossible to operate the switch due to the abnormality processing by the abnormality processing execution means.If an abnormality due to fraudulent activity is detected during the fluctuation display of the symbol string, the progress of the game being executed is stopped by setting a state in which the symbol string during the fluctuation display is not stopped, and the medal payout process is performed. If it has been done, this process will be forcibly terminated, so that it is possible to prevent a prize from being won or an illegal medal being paid out due to a game involving fraudulent acts, which greatly increases security. Can do.
[0011]
  In a preferred embodiment slot machine,Storage means for storing the progress status of the program being executed is further provided. In addition, when the abnormality content determining unit determines that the detected abnormality is an abnormality caused by a cause other than an illegal act, the abnormality handling unit is configured to store information stored in the storage unit in response to the removal of the abnormality. On the other hand, when the abnormality content determination means determines that the detected abnormality is an abnormality due to fraud, the storage means returns to the execution state of the program before the abnormality detection based on the Clear the stored contents of.
  According to this aspect, when an abnormality due to a cause other than an illegal act is detected, when the abnormality is removed, it is possible to return to the process that was being performed when the abnormality was detected. However, when an abnormality due to an illegal act is detected, the stored contents of the storage means are cleared when the abnormality is removed, so that the program is executed from the beginning.
[0012]
  furtherAccording to another preferred embodimentSlot machineProvided with means for executing a medal lending process for a game on condition that the card processing machine is electrically connected to a card processing machine arranged at an adjacent position and the card processing machine has received a value-added card. To do. The abnormality detecting means detects that an error detection signal accompanying insertion of an unauthorized card from the card processor is transmitted as an abnormality, and the abnormality content determining means determines the abnormality as an abnormality due to an illegal act.
  According to this aspect, even when an illegal card is inserted into the card processing machine, the same processing as when an illegal act is performed on the slot machine body is executed. Can be prohibited.
[0013]
According to the above aspect, even if an illegal act is performed in which a game medium that can be pulled back, such as the above-described thread-suspended medal, is inserted and the game medium is displayed after the symbol change display is started, the pull-back operation is performed. Since the state in which the symbol variation display cannot be stopped is set with certainty, the game due to illegal use of the game medium can be aborted halfway, and the restart and the start of a new game can be completely prohibited.
[0014]

[0017]
In particular, the front panel 11 is used as an area for displaying the progress of the game. An uncolored and transparent symbol display window 20 is formed at the center of the front panel 11, and a stored number display 24, a payout number display 25, and a stop display lamp 26a are provided around the symbol display window 20. , 26b, 26c, etc. are provided.
[0018]
The reels 8 a, 8 b, 8 c are arranged behind the symbol display window 20 with the outer peripheral surface facing the symbol display window 20. The symbol display window 20 has a horizontal length so that the three reels 8a, 8b, and 8c can be seen from the outside, and a vertical length can be seen from the outside when the reels are stopped. Thus, it is formed in a rectangular shape that is long horizontally. Further, on the surface of the symbol display window 20, a total of five winning lines L are drawn, three in the horizontal direction and two in the diagonal direction so as to connect the stop display positions of the respective symbols.
[0019]
Between the front panel 11 and the lower panel 13, a medal slot 16 for receiving medals for games, a start lever 14 for rotating the reels 8a, 8b, 8c all at once, and the reels 8a, 8b, 8c. In addition to the stop button switches 15a, 15b, 15c for individually stopping, three bet button switches 17, 18, 19, a settlement switch 21, a changeover switch 22, a door lock 23, and the like are provided. Further, below the lower panel 13, a medal payout port 27, a medal tray 28, and the like are provided.
[0020]
The bet button switches 17, 18, 19 are used when a credit-type game is executed by withdrawing medals stored in an electronic data format. By operating the bet button switches 17, 18, 19, Three, two, and one medal are drawn, respectively. The settlement switch 21 is used to settle the stored medals and pay out the medals for the number of stored medals from the medal payout exit 27. The changeover switch 22 is used to switch between a mode (manual mode) in which a medal is inserted from the medal slot 16 and a game is executed (credit mode).
[0021]
Note that the number of stored medals in the credit mode is displayed on the stored number display 24. The payout number display unit 25 displays the number of medals to be paid out as a reward when a winning is achieved by the game. The stop display lamps 26a, 26b, and 26c are used for notifying whether or not the reels 8a, 8b, and 8c can be stopped. When the reels 8a, 8b, and 8c are started, a predetermined time elapses. Turns on and turns off in response to the operation of the stop button switches 15a, 15b, 15c.
The payout number display unit 25 also functions as a display unit for notifying the content of an abnormality when an abnormal state is detected by an abnormality detection process described later.
[0022]
The door lock 23 includes a lock mechanism 23a that can be rotated to the left and right. By rotating the lock mechanism 23a to the right by using an attached key (not shown), the door main body 2 is moved forward. The door 3 is locked. Further, by rotating the lock mechanism counterclockwise, a reset switch, which will be described later, is closed to reset each part of the machine body to the initial state.
[0023]
The medals inserted from the medal insertion slot 16 pass through the medal selector inside the machine body, and are sent out to any one of the hopper 6a, the auxiliary hopper 6b, and the medal tray 28.
FIG. 3 shows a schematic configuration of the medal selector 30. In the figure, reference numeral 31 denotes a medal passage that communicates with the medal payout port 16, and a medal passage 31 that includes three medal detection sensors 32, 33, and 34 is provided in the medal passage 31. The medals inserted from the medal insertion slot 16 are guided to one of the three paths described above by the operation of a passage switching mechanism (not shown).
[0024]
Each medal detection sensor 32, 33, 34 is composed of, for example, a photoelectric sensor, and is arranged at an appropriate distance along the rolling direction of the medal. The center sensor 33 is arranged at a position close to the bottom surface of the medal passage 31, whereas the sensors 32 and 34 at both ends are arranged at height positions corresponding to the size of the medal. The photoelectric sensor is normally in an on state in which light from the light projecting unit is received, but when the medal passes the sensor installation position, the light from the light projecting unit is blocked for the passage time. , Return to the ON state after passing. Therefore, when one medal is properly inserted, as shown in FIG. 4 (1), an output change in an off state for a predetermined period is obtained in order from the upstream medal detection sensor.
[0025]
On the other hand, when a fraudulent operation is performed in which a thread-hanging medal is inserted into the medal insertion slot 16 and reciprocated, as shown in FIG. After changing in the same way as when it was put in, it changes in the reverse order. Further, when a medal is jammed in the medal selector 30, a state in which an output change cannot be obtained as shown in FIG. 4A occurs, for example, one of the medal detection sensors is always turned off.
[0026]
Outputs from the medal detection sensors 32, 33, and 34 are given to the control unit 40 described later, and the control unit 40 changes the outputs of these sensors 32, 33, and 34 different from those in FIG. Is shown, it is determined that an abnormality has occurred in the passage of medals.
[0027]
In the slot machine 1, a medal is paid out from the medal payer 6 at a timing unrelated to the medal passing abnormality in the medal selector 30, the medal payout at the time of winning a prize, and the settlement of the stored medal, During the execution, the front door 3 may be illegally opened and the medal in the hopper 6a may be exploited, or malfunctions may occur due to various fraudulent actions such as malfunction of the reel rotation and medal payout due to external radio noise. There is. In addition to cheating, abnormalities such as clogging of medals with the medal selector 30 and the hopper 6a, emptying of the hopper 6a, and fullness of the hopper 6a and the auxiliary hopper 6b may occur, which hinders game control. I have come.
In the slot machine 1 of this embodiment, regardless of whether or not a game is in progress, an interrupt is generated for normal control at every predetermined time to determine whether there is an abnormality. When an abnormality is detected, the operation of various switches is not accepted thereafter, and the display of the payout number display unit 25 is switched to display code information indicating the content of the detected abnormality or output an alarm. An abnormal process such as doing is performed.
[0028]
In particular, in this slot machine 1, when an abnormality associated with an illegal act called “got” is detected in a state where the reel is rotating, the progress of the game is stopped by continuing the rotation of the reel. Yes. Under this state, the operation of all the switches including the reel stop operation is invalidated, and it is impossible to restart the game or start a new game.
[0029]
FIG. 5 shows a main electrical configuration in the slot machine 1. The above-described control unit 40 includes a memory such as a ROM 42 and a RAM 43 with a CPU 41 as a control subject. The control unit 40 includes various game switches (shown as a game switch group 44 in the figure) including a start lever 14 and stop button switches 15a, 15b, 15c, a reel unit 4, and a medal dispensing machine 6. In addition to the passing medal detection unit 35, a payout medal detection unit 36, a door open / close state detection unit 37, a display control circuit 45, a medal discharge switch 38, a reset switch 39, and the like are connected.
[0030]
The payout medal detection unit 36 is for detecting medals paid out from the medal payer 6 and for checking the medal accommodation state of the hopper 6a and the auxiliary hopper 6b. The hopper 6a, the auxiliary hopper 6b, and the medal payout port It is composed of a plurality of medal detection sensors arranged in a medal passage up to 27.
[0031]
The door open / closed state detection unit 37 is for detecting the open / closed state of the front door 3, and is configured by, for example, a push button type switch or a limit switch arranged inside the front door 3.
The display control circuit 45 is for controlling display operations of the stored number display 23, the payout number display 24, and the like. The medal discharge switch 38 is a switch provided at the medal payer 6 in the machine body or at a position near the medal payer 6 and is used for discharging all medals in the hopper 6a.
[0032]
The reset switch 39 closes by the turning operation of the door lock 23 and outputs a reset signal to the CPU 41. The CPU 41 clears a partial area of the RAM 42 or the entire RAM 42 in response to the reset signal. Is restored to the state before the error occurred or to the initial state.
[0033]
FIG. 6 shows a main control procedure concerning the game in the slot machine 1. In FIG. 6 and the following description, each processing step is indicated as ST.
The procedure shown in FIG. 6 starts in response to the insertion of a medal from the medal insertion slot 16 or the operation of the bet button switches 17, 18, and 19. First, in ST1, the number of winning lines L corresponding to the inserted medals or the operated bet button switch is validated, and then the process proceeds from ST2 to ST3 according to the operation of the start lever 14, and each reel 8a, 8b , 8c are started all at once.
[0034]
The next ST4 is to confirm whether or not a stop control release command has been issued in an abnormal process described later. Usually, this determination is “NO”, and the process proceeds to ST5. If any one of the stop button switches 15a, 15b, 15c is operated in this state, ST5 becomes “YES” and the process proceeds to ST6, and the reel corresponding to the operated switch is stopped at a predetermined timing. Thereafter, the process returns from ST7 to ST4, and thereafter the corresponding reel is stopped each time the remaining stop button switch is operated.
[0035]
When all the reels 8a, 8b, 8c are stopped in this way, ST7 becomes “YES” and the process proceeds to ST8 to check whether or not a winning is achieved. Here, if the winning symbols L are aligned on the activated winning line L, ST9 becomes “YES” and the process proceeds to ST10, and a predetermined number of medals are paid out from the medal payer 6 (however, In the case of the credit mode, medals corresponding to the number of payouts may be added to the stored medals), and the process ends.
[0036]
In this embodiment, while the reel is rotating, while waiting for a stop operation, the passage of time is checked (ST5, 11), and even if a predetermined time T seconds elapses from the start of the reel. If the stop operation is not performed, the process proceeds from ST11 to ST12 to forcibly stop the reels 8a, 8b, and 8c. Even when one or two reels are stopped, if the next reel stop operation is not performed even after T seconds have elapsed since the previous reel stop operation, the process proceeds from ST11 to ST12 in the same manner. The reels are forcibly stopped, and then the process proceeds to ST8. However, if a stop control release command is received from the start of each reel 8a, 8b, 8c to the end of the rotation of all reels, the determination in ST4 is "YES", and thereafter the game Control is stopped and the process proceeds to a standby process procedure (not shown).
[0037]
FIG. 7 shows a control procedure for abnormality processing. In this procedure, numbers after 31 are assigned to each step (ST). Actually, however, the procedure is in a state where the player is waiting for an operation, or in the state where the procedure of FIG. 6 is being executed. In addition, when accepting the insertion of medals, when performing the settlement processing of stored medals, etc., under the state of executing a program related to normal processing (hereinafter collectively referred to as “main program”), It is executed by generating an interrupt every predetermined time.
[0038]
First, in ST31, detection signals from the passing medal detection unit 35, the payout medal detection unit 36, the door open / close state detection unit 37, and the like are fetched to determine whether any abnormality has occurred.
For example, if a change as shown in FIG. 4 (2) appears in the detection output from each medal detection sensor 32, 33, 34 of the passing medal detection unit 35, it is assumed that a fraudulent act by a thread hanging medal is performed. to decide. If one or more medal detection sensors 32, 33, 34 are continuously off, it is determined that the medal clogging has occurred in the medal selector 30.
[0039]
The payout medal detection unit 36 checks whether or not there is a lack of medals or a full state of medals using a detection output from a medal detection sensor provided in the hopper 6a or the auxiliary hopper 6b. Further, it is checked whether or not a medal clogging has occurred by the detection output of the medal detection sensor provided in the medal passage to the medal payout exit 30. In addition, when an operation signal for the medal discharge switch 38 is received in a state where a detection signal indicating that the front door 3 is opened is output from the door open / close state detection unit 37, the medal is illegally discharged. It is determined that the act of exploiting is performed.
[0040]
Of the various abnormalities described above, for medal clogging, the criterion is that the medal detection sensor remains off for a predetermined time or more, so in ST31, a sensor obtained by a past predetermined number of interruptions. You need to check the output. In addition, regarding the illegal discharge of medals, the medal discharge switch 38 may not be set depending on the model, so that a change occurs in the detection output of the payout medal detection unit 36 when the opening of the front door 3 is detected. It may be determined that an abnormality has occurred.
[0041]
Furthermore, in this ST31, in order to cope with an illegal act (radio wave) caused by the action of radio waves or the like, whether or not an error has occurred in the execution process of the main program or if the medal dispenser 6 is operating is set. It is checked whether or not the number of medals exceeding the paid out number has been paid out.
[0042]
If it is determined in ST31 that some kind of abnormality has occurred, ST32 becomes “YES” and the process proceeds to ST33, where the abnormality that has occurred is caused by an illegal act (detection of a suspended medal, unauthorized medal discharge, radio wave) Error occurrence etc.).
[0043]
If this determination is “YES”, in the next ST34, the abnormality content is displayed on the payout number display unit 25 or an alarm is output to notify the occurrence of the abnormality. Set the acceptance prohibition state that does not accept the operation. In the next ST36, it is checked whether or not the reel is currently rotating. If the determination in ST36 is “YES”, that is, if an illegal act is being performed during reel rotation, the process proceeds to ST37, and a reel stop control release command is output to the execution environment of the main program. If the medal payer 6 is illegally driven by the operation of the medal discharge switch 38 or radio noise, the next ST38 is “YES” and the process proceeds to ST39 to forcibly operate the medal payer 6. Stop.
[0044]
On the other hand, if an abnormality (such as a clogged medal, a lack of medals in the hopper 6a, a full state of the auxiliary hopper 6b, etc.) has occurred, ST33 becomes “NO” and the process proceeds to ST40. Perform error handling accordingly.
In ST40, a state in which the game cannot be started is set while notifying the occurrence of an abnormality by performing basically the same processing as in ST34 and 35. However, if an abnormality is detected during the rotation of the reels, execution of error processing is delayed until at least all the reels 8a, 8b, 8c are stopped so that the game being executed is not affected. Furthermore, even when medals are paid out due to the establishment of a prize, unless the detected abnormality causes a medals to be paid out such as a lack of medals in the hopper 6a or a clogged medal at the medal payout exit 30, After the process is completed, the process proceeds to an abnormal process.
[0045]
In this way, when the occurrence of an abnormality is detected during the game execution or during the standby period, and the machine becomes unusable, the execution of the main program is stopped and the process proceeds to the standby process described above. In this standby processing, it is checked whether or not the abnormality has been removed while maintaining a state in which all switch operations are invalidated. When the clerk removes the cause of the abnormality based on the code information displayed on the payout number display unit 25 and performs a reset operation by rotating the door lock 22, the CPU 41 ends the abnormality process and an abnormality occurs. Return to the previously executed main program procedure and resume processing. However, it is desirable to clear the entire RAM 43 and to start the program from the beginning for an abnormality caused by an illegal act.
[0046]
According to this embodiment, the error detection process is performed not only during the standby period in which the game is not being executed but also during the game, so that, for example, a sling medal is inserted and the game is started, and then the medal is pulled back. When such an action is performed, a state in which the reel cannot be stopped as soon as the medal pullback is detected is set, so that it is possible to prohibit the game from being executed due to illegal use of the medal. For other cheating activities, if cheating is detected while the game is running, the cheating is detected immediately and the game cannot be advanced. The security of the slot machine can be greatly increased.
[0047]
In the above procedure, if an abnormality due to fraud is detected during reel rotation, the game is stopped by setting the reel rotation to an unstoppable state. It may be forcibly stopped at a timing when winning is not established.
Also, when an abnormality due to fraud is detected during the medal payout process at the time of winning a prize or during the settlement process of stored medals, the payout operation of the medal payer 6 is forcibly terminated and no operation is accepted thereafter. desirable.
[0048]
Further, in recent years, a card processing machine is arranged in an adjacent position and electrically connected to the card processing machine, and a medal lending process for a game is performed on condition that a card with a valuable value is received by the card processing machine. Although a slot machine has been proposed, an error detection signal is transmitted to the slot machine when an abnormal state such as an illegal card being inserted is detected on the card processor side in such a model. By doing so, it is possible to execute error processing similar to the above on the slot machine side and prohibit medal lending to the fraudster.
[0049]
【The invention's effect】
  As described above, in the present invention,When an abnormality due to cheating is detected, the game cannot be executed by setting a reception prohibition state in which all switch operations are not accepted.When abnormalities due to fraud are detected during symbol display, the game progress is stopped by setting a state in which the symbol display is not stopped, and medals are being paid out. Since the payout process is forcibly terminated, it is possible to prevent an unfair profit from being paid out to a fraudulent person due to a game involving fraudulent acts, and to provide a slot machine with high security. In addition, if an abnormality due to a cause other than fraudulent activity is detected while the symbol row is changing,AllUntil the variable display of the symbol column stopsAbnormal processingWill delay the execution ofAbnormal processingIt is possible to prevent the influence of.
