  <Control unit>

  Next, the circuit configuration of the main control unit 300 of the slot machine 100 will be described in detail with reference to FIG. The figure shows a circuit block diagram of the main control unit 300.

  The control unit of the slot machine 100 is roughly divided into a main control unit 300 that controls the central part of the game and a sub-control unit 400 that controls various devices in accordance with commands transmitted by the main control unit 300.

  The main control unit 300 includes a CPU 310 that is an arithmetic processing unit for controlling the entire main control unit 300, a data bus and an address bus for the CPU 310 to transmit and receive signals to and from each IC and each circuit, It has the structure described below. The clock correction circuit 314 is a circuit that divides the clock generated by the crystal oscillator 311 and supplies it to the CPU 310. For example, when the frequency of the crystal oscillator 311 is 12 MHz, the divided clock is 6 MHz. The CPU 310 operates by receiving the clock divided by the clock correction circuit 314 as a system clock.

  The CPU 310 is connected to a timer circuit 315 for setting a timer interrupt processing cycle for constantly monitoring the sensor and switch states and a motor drive pulse transmission cycle via a bus. When the power is turned on, the CPU 310 transmits the frequency dividing data stored in the predetermined area of the ROM 312 to the timer circuit 315 via the data bus. The timer circuit 315 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 310 at each interrupt time. In response to this interrupt request, the CPU 310 executes monitoring of each sensor and transmission of drive pulses. For example, when the system clock of the CPU 310 is set to 6 MHz, the frequency division value of the timer circuit 315 is set to 1/256, and the data for frequency division of the ROM 312 is set to 44, the reference time of this interrupt is 256 × 44 ÷ 6 MHz = 1. 877 ms.

The stop button sensor 322 is a sensor for detecting which stop button is pressed when any one of the stop buttons 137 to 139 is pressed. The medal insertion button sensor 323 is a sensor for detecting which medal insertion button is pressed when one of the medal insertion buttons 130 and 131 is pressed. The settlement switch sensor 324 is provided on the settlement button 132. When the settlement button 132 is pressed once, the stored medals and the bets placed on the settlement are settled and paid out. The other medal insertion sensor 320, medal payout sensor 326, door opening detection sensor 327, and setting key sensor 328 are as described above.

  The CPU 310 further has an input interface 361 and output interfaces 370 and 371 connected to an address bus via an address decoding circuit 350. The CPU 310 exchanges signals with external devices via these interfaces. An index sensor 325 is connected to the input interface 361, and the index sensor 325 becomes a high level every time a light shielding piece provided on the reels 110 to 112 passes. When detecting this signal, the CPU 310 determines that the reel has made one rotation, and resets the rotational position information of the reel to zero. The output interface 370 includes a reel motor driving unit 330 that controls a motor for driving the reel, a hopper motor driving unit 331 for driving the motor of the hopper 172, and a game lamp 340 (a winning line display lamp 120, a start A lamp 121, a replay lamp 122, a notification lamp 123, a medal insertion lamp 124, etc.), a 7 segment (SEG) indicator 341 (a payout number display 125, a game number display 126, a stored number display 127, etc.); An external concentration terminal board 450 described later is connected.

  Further, a random number generation circuit 317 is connected to the CPU 310 via a data bus. The random number generation circuit 317 is an increment counter capable of incrementing a value within a certain range based on a clock oscillated by the crystal oscillator 311 and the crystal oscillator 316 and outputting the count value to the CPU 310, which will be described later. Used for various lottery processes, including internal lottery for winning positions. An output interface 371 for transmitting a command to the sub control unit 400 is connected to the data bus of the CPU 310. Information communication between the main control unit 300 and the sub control unit 400 is a one-way communication, and the main control unit 300 transmits a command to the sub control unit 400. Cannot be sent.

The external concentration terminal board 450 includes a signal input circuit 452, a signal transmission circuit 454, and a signal output circuit 456. The signal input circuit 452 (for example, a connector) includes 10 input terminals 1 to 10, the serial signal line of the motor drive board 300 b is input to the input terminal 1, and the parallel signal of the motor drive board 300 b is input to the input terminals 2 to 7. A + 24v power source is connected to the input terminals 8 to 10 respectively. The signal transmission circuit 454 includes a light emitting diode 454a, a relay 454b having an electromagnetic coil and a mechanical switch, and the like. The signal output circuit 456 (for example, a connector) includes eight output terminals 1 to 8, and a relay common signal line of an information providing terminal board 500 (described later) is connected to the output terminals 1 to 5 and 7. Is connected to the parallel signal line of the information providing terminal board 500 and the output terminal 8 is connected to the serial signal line of the information providing terminal board 500.

  When a low level signal is input to the input terminals 1 to 7 of the signal input circuit 452, the light emitting diode 454a is turned on and the electromagnetic coil of the relay 454b is activated to turn on the mechanical switch (closed state). As a result, the external concentration terminal plate 450 outputs a low level signal from the output terminals 1 to 5, 7, and 8 of the signal output circuit 456 corresponding to the relay 454b that is turned on. On the other hand, when a high level signal is input to the input terminals 1 to 7 of the signal input circuit 452, the light emitting diode 454a is turned off and the operation of the electromagnetic coil of the relay 454b is stopped to turn off the mechanical switch (open state).

  Next, after restarting WDT in Step S102, in Step S103, it is determined whether or not the voltage drop signal output from the power supply board 460 is on, that is, whether or not a predetermined voltage is supplied to the slot machine 100. Judging. When the voltage drop signal is on (when a predetermined voltage is not supplied to the slot machine 100), the process returns to step S102, and when the voltage drop signal is off (a predetermined voltage is supplied to the slot machine 100). If so, the process proceeds to step S104.

  In the initial setting 2 in step S104, initialization processing such as initialization of the RAM 313 and interrupt setting is executed, and then the processing proceeds to the main processing.

  <Main processing>

  Next, the main process of the main control unit 300 will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of main processing of the main control unit 300.

  Basic control of the game is performed mainly by the Main CPU 310 of the main control unit 300, and the Main CPU 310 repeatedly executes the main processing of FIG.

  In step S201, the storage area (variable) used for security signal transmission is cleared (initialized) among all the storage areas of the RAM 313. Specifically, 0 is set in a security information change accumulation information area, a security signal information area, a signal output timer information area, and an output bit remaining number information area described later.

  In step S202, in order to forcibly output the state composite signal when the power is turned on, an initial value (3 in this example) is set in signal output remaining number information (details will be described later) provided in the RAM 313. In this way, when the power is turned on, the state composite signal is forcibly output a plurality of times (in this example, three times), so that the power is turned off using an unauthorized device without opening and closing the door, and the setting value is illegally changed. Such fraudulent behavior may be detected early. Further, by outputting the same state composite signal a plurality of times in succession, an external device that has received the same state composite signal a plurality of times continuously may recognize that the power of the gaming machine has been turned on.

  In step S203, an initial value (a numerical value corresponding to 720 ms in this example) is set in a security signal output standby timer (details will be described later) provided with a storage area in the RAM 313.

  Next, in step 205, it is determined whether a setting key is accepted based on the state of the setting key sensor 328. If the setting key has been received, the process proceeds to a setting change process in step S206. If the setting key has not been received, the process proceeds to step S207.

  In step S206, a setting change process is performed. Although the details will be described later, in this setting change process, first, the setting of the function-limited wait is canceled, the interrupt permission is set, and then the setting value is changed.

  In step S207, it is determined whether or not to return to the state before power interruption (before power supply interruption). And when returning to the state before power interruption, it progresses to step S208, and when that is not right, it progresses to step S210.

  In step S208, after setting a function-restricted wait so that the interrupt function waits for a predetermined time in timer interrupt processing (described later) (after storing information indicating that the function is limited in a predetermined storage area of the RAM 313) ) In step S209, the stack pointer stored at the time of power interruption is reset in the stack pointer, and the process at the time of power recovery is performed and the process ends.

  In step S210, game medal insertion processing is performed. Although details will be described later, in this game medal insertion process, the setting of the function-limited weight is canceled and the interrupt permission is set, and then a process related to medal insertion is performed.

  In step S211, processing relating to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated based on the state of the start lever sensor 321. If it is determined that the start operation has been performed, the number of inserted medals is determined.

  In step S212, the random number generated by the random number generator 317 is acquired.

  In step S213, an internal lottery of a winning combination is performed using the random number acquired in step S212 and the lottery data stored in the ROM 312.

  In step S214, rotation of all reels 110 to 112 is started by reel rotation start processing. At this time, the reel stop control table that defines the stop positions of the reels 110 to 112 is selected based on the result of the internal lottery in step S213.

  In step S215, it is checked whether or not the stop buttons 137 to 139 are operated based on the state of the stop button sensor 322. If it is determined that the stop buttons 137 to 139 are operated, the reel stop selected in step S214 is performed. Based on the control table, the rotation of the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 is stopped. Then, based on the state of the index sensor 325, it is determined whether or not all the reels 110 to 112 are stopped. If all the reels 110 to 112 are stopped, the process proceeds to step S216. Wait until 139 is operated and all reels 110 to 112 are stopped.

  In step S216, the winning determination of the symbols of all the reels 110 to 112 stopped by pressing the stop buttons 137 to 139 is performed. Here, it is determined that the winning combination has been won when the symbol combination corresponding to the winning combination internally or the winning combination is displayed (displayed) on the activated winning line 114.

  In step S217, medal payout processing is performed. In this medal payout process, if a winning combination is awarded, the number of medals corresponding to the winning combination is paid out.

  In step S218, control for ending the game and control for shifting the game state are performed. For example, in the case of BB winning or RB winning, preparation is made so that the BB game or RB game can be started from the next time, and in those final games, preparation is made so that the normal game can be started from the next time.

  Thus, one game is completed, and thereafter, the game proceeds by repeating this main process.

  <Setting change processing>

  Next, the setting change process (step S206) in the main process described above will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of setting change processing.

  In step S301, among the bits of the security state information stored in the RAM 313, a bit corresponding to error information D2 (setting signal) to be described later is set to 1 (hereinafter, setting the bit to 1 means “turning the bit ON”). There is a case of "

  In step S302, it is determined whether or not the count value of the security signal output standby timer information stored in the RAM 313 has passed a predetermined time (in this example, 720 ms). If the predetermined time has passed, step S302 is executed. In step S303, if the predetermined time has not elapsed, the process waits for the predetermined time to elapse in step S302.

  In step S303, after the set value change acceptance process is performed, the process ends. In this setting change acceptance process, the setting values of setting 1 to setting 6 are changed when a setting operation by a store clerk or the like using a predetermined operation unit provided on the game machine is detected while the setting change flag is on. Perform the process. During the setting value changing process, the signal from the setting key sensor 328 is monitored, and the setting key sensor 328 waits for a change from a state indicating that the setting is being changed to a state where the setting change is completed. When the setting key sensor 328 changes to a state where the setting change is completed, the setting changing flag is turned off, and the bit corresponding to the error information D2 (setting signal) among the bits of the security state information stored in the RAM 313 is set to 0. Then, the process proceeds to step S210 (hereinafter, setting the bit to 0 may be referred to as “turning the bit OFF”).

  <Game medal insertion process>

  Next, the game medal insertion process (step S210) in the main process described above will be described with reference to FIG. This figure is a flowchart showing the flow of the game medal insertion process.

  In step S401, the signal from the setting key sensor 328 is monitored to determine whether the setting key is on or off. If the setting key is off, the process proceeds to step S406. If the setting key is on, the process proceeds to step S402. .

  In step S402, whether or not a medal is inserted is checked based on the state of the medal insertion sensor 320. If no medal is inserted, the process proceeds to step S406. If a medal is inserted, the process proceeds to step S403.

  In step S403, a bit corresponding to error information D2 (setting signal), which will be described later, is turned ON among the bits of security status information stored in the RAM 313. In step S404, the setting is made using a display device provided inside the game machine. Display the value. A store clerk or the like of a game store can check the current set value of the game stand by looking at the set value displayed on the display device.

  In step S405, a signal from the setting key sensor 328 is monitored to determine whether the setting key is on or off. If the setting key is off (when the setting confirmation is completed), the process proceeds to step S406, where the setting key If is turned on (if the setting check has not been completed), the system waits for the setting key to turn off.

  In step S406, the bit corresponding to the error information D2 (setting signal) among the bits of the security status information stored in the RAM 313 is turned OFF, and then other insertion processing (for example, winning according to the number of inserted medals). For example, a process of lighting the line display lamp 120).

  <Timer interrupt processing>

  Next, timer interrupt processing executed by the Main CPU 310 of the main control unit 300 will be described with reference to FIG. This figure is a flowchart showing the flow of timer interrupt processing.

  The Main CPU 310 includes a hardware timer that generates a timer interrupt at a predetermined cycle (about once every 1.504 ms in the present embodiment), and executes timer interrupt processing at a predetermined cycle triggered by the timer interrupt.

  In step S501, each register of the Main CPU 310 is saved in the stack.

  In step S502, the value of the input port is acquired and the states of various sensors (medal insertion sensor 320, start lever sensor 321, stop button sensor 322, medal payout sensor 326, door opening detection sensor 327, setting key sensor 328, etc.) are changed. To detect. More specifically, signals output from a plurality of sensors such as a medal insertion sensor 320, a start lever sensor 321, a stop button sensor 322, a medal payout sensor 326, a door opening detection sensor 327, a setting key sensor 328, and the like are input. It is determined whether the output from each sensor is on or off.

  In step S503, it is determined whether or not the interrupt function is limited, that is, whether or not a function limit weight is set in the main processing (information indicating that the function is limited is stored in a predetermined storage area of the RAM 313). Or not). When the interrupt function is limited (when a function-limited weight is set), the process proceeds to step S509 without performing the processing of steps S504 to S508, and when the interrupt function is not limited (the function-limited weight is set). If not set), the process proceeds to step S504.

  In step S504, game medal insertion acceptance processing is performed. Although details will be described later, in this game medal insertion acceptance process, processing related to the insertion of game medals is performed based on the current gaming state, the prescribed number of medals required for one game, and the like.

  In step S505, reel control processing such as rotation control and stop control of the reels 110 to 112 is performed, and in step S506, other processing is performed.

  In step S507, data output to the game lamp 340 (upper lamp 150, side lamp 151, center lamp 152, waist lamp 153, lower lamp 154, saucer lamp 156, etc.) is updated.

  In step S508, a constant error monitoring process is performed. As will be described in detail later, in this constant error monitoring process, based on the state of the medal payout sensor 326 detected in step 502, an error such as the hopper 172 is monitored and error detection information is updated.

  In step S509, concentrated terminal board signal setting processing is performed. Although details will be described later, in this concentrated terminal board signal setting process, a state composite signal is generated based on the security state information stored in the RAM 313 and serially output. Further, a medal insertion signal, a medal payout signal, and external signals 1 to 4 are generated based on medal insertion information stored in the RAM 313 and output in parallel.

  In step S510, data to be output to the 7SEG display 341 is set. In step S511, data to be output to the reel motor control unit 330, the hopper motor control unit 331, or the like is set.

  In step S512, a control command is output to the sub-control unit 400. In step S513, various counter timers (for example, the above-described security signal output standby timer) stored in the RAM 313 are updated.

  In step S514, it is determined whether or not the voltage drop signal output from the power supply board 460 is ON, that is, whether or not a predetermined voltage is supplied to the slot machine 100. If the voltage drop signal is on (when a predetermined voltage is not supplied to the slot machine 100), the process proceeds to step S517. If the voltage drop signal is off (a predetermined voltage is supplied to the slot machine 100). If so, the process proceeds to step S515.

  In step S515, the register saved in step S501 is restored, and in step S516, an interrupt is set to be permitted.

  In steps S517 to S520, a power interruption process is performed. More specifically, in step S517, the current stack pointer is saved, and in step S518, the power status is updated to “power failure”. In step S519, the checksum is calculated and set using the value stored in the RAM 313. In step S520, writing to the RAM 313 is prohibited, and an infinite loop is entered. Although not shown, in the present embodiment, when the state composite signal is output at the time of the power interruption process, the state composite signal is output as a state composite signal after all the state composite signals output to the middle are output. A signal (low level signal in this embodiment) is output.

  <Game medal insertion acceptance process>

  Next, the game medal insertion acceptance process (step S504) in the above-described timer interrupt process will be described with reference to FIG. This figure is a flowchart showing the flow of the game medal insertion acceptance process.

  In step S601, based on the on / off information of the start lever sensor 321 detected in the above-described input port monitoring process (step S502), it is determined whether an operation of the start lever 135 has been accepted. If the operation of the start lever 135 is accepted, the process proceeds to step S602. If the operation of the start lever 135 is not accepted, the process is terminated.

  In step S602, a bit corresponding to error information D5 (preliminary signal) to be described later is turned ON among the bits of security state information stored in the RAM 313. In step S603, a preliminary signal (state composite signal) is based on the security state information. Is output.

  In step S604, a preliminary signal is output in a manner in accordance with a notification pattern of a notification device (not shown) provided outside the game stand (for example, an island of a game store). For example, in the case of a notification pattern in which a lamp provided in the notification device is turned on for a predetermined time (for example, 500 ms) when the start lever 135 is pressed down by the player, the slot machine 100 sends an on-level preliminary signal in step S603. In step S604, the elapse of a predetermined time (500 ms) is monitored, and when the predetermined time elapses, an off-level standby signal is output.

  In step S605, selector processing is performed. Although details will be described later, in this selector process, the medal selector 170 is monitored for errors and the error detection information is updated based on the state of the medal insertion sensor 320 detected in the input port monitoring process (step S502). Do.

  In step S606, after other processing is performed, the processing ends.

  <Selector reception processing>

  Next, the selector process (step S605) in the above-described game medal insertion acceptance process will be described with reference to FIG. This figure is a flowchart showing the flow of selector processing.

  In step S701, the sensor waveform of the medal selector 170 is confirmed, and in step S702, it is determined whether there is an abnormality in the sensor waveform. Specifically, the waveform pattern output from the medal insertion sensors 1 and 2 when the inserted medal normally passes through the medal insertion sensors 1 and 2, and the actual medal insertion sensors 1 and 2 When the waveform patterns are compared with each other and they are different, it is determined that the inserted medal does not normally pass the medal insertion sensors 1 and 2 (medal insertion abnormality 2). If there is an abnormality in the waveform, the process proceeds to step S703, and if there is no abnormality in the waveform, the process proceeds to step S705.

  In step S703, a bit corresponding to error information D3 (selector signal) to be described later is turned ON among the bits of the security state information stored in the RAM 313. In step S704, error information (this information is added to the error detection information provided in the RAM 313). In the example, information indicating medal insertion abnormality 2) is set.

  In step S705, the medal passage is monitored, and in step S706, it is determined whether or not there has been an illegal insertion of medals. Specifically, the rising of the signal of the medal insertion sensor 3 is detected after the medal has passed normally, and if the medal insertion sensor 3 has never fallen when five medals have passed normally thereafter, the medal insertion (medal It is determined that the charging is abnormal 4). If there is an illegal insertion of a medal, the process proceeds to step S707, and if there is no illegal insertion of a medal, the process ends.

  In step S707, a bit corresponding to error information D3 (selector signal) to be described later is turned ON among the bits of security status information stored in the RAM 313. In step S708, error information (this information is added to the error detection information provided in the RAM 313). In the example, information indicating medal insertion abnormality 4) is set. Note that the error detection method and error information of the medal selector 170 are not limited to these. For example, in this embodiment, when the medal insertion sensor 1 detects that the inserted medal is retained, the medal When the insertion error 1 is set and the medal insertion sensor 3 is set when either the medal insertion sensor 1 or 2 is turned on except during the medal insertion process, and the insertion sensor 4 is kept on for a certain time or more. Is configured to set a medal insertion abnormality 5.

  <Continuous error monitoring process>

  Next, the constant error monitoring process (step S508) in the above-described timer interrupt process will be described with reference to FIG. This figure is a flowchart showing the flow of the constant error monitoring process.

  In step S801, it is determined whether or not a medal payout has been detected except when the hopper 172 is in operation, that is, whether or not an illegal medal payout has been detected. Specifically, when either the payout sensor 1 or 2 is turned on other than during medal payout (for example, during execution of the game medal payout process in step S217 above), an illegal payout of a medal is detected ( The medal payout abnormality 3) is determined. The process proceeds to step S802 if an unauthorized payout of medals is detected, and proceeds to step S804 if an unauthorized payout of medals is not detected.

  In step S802, a bit corresponding to an error signal D4 (hopper signal) to be described later is turned ON among the bits of the security state information stored in the RAM 313. In step S803, error information (this information is added to the error detection information provided in the RAM 313). In the example, information indicating medal payout abnormality 3) is set. The error detection method and error information of the hopper 172 are not limited to these. For example, in this embodiment, when the hopper 172 is driven, the medal payout sensors 1 and 2 remain off and no medal is paid out for a certain period of time. If the medal payout abnormality 1 is set, the medal payout abnormality 1 is set when the medal payout sensors 1 and 2 remain on when the hopper 172 is driven, and the medal payout abnormality 2 remains. Alternatively, the medal payout abnormality 3 is set when any one of 2 is turned on or when it is detected that the signal line connecting the main control unit 300 and the hopper 172 is disconnected.

  In step S804, it is determined whether or not the insertion of a medal has been detected even though the medal blocker (not shown) that temporarily prevents the insertion of the medal is in a closed state (in a position where the insertion of the medal is blocked). Specifically, when either of the medal insertion sensors 1 or 2 is turned on while the medal blocker is controlled to be in the closed state, it is determined that the medal is illegally inserted (medal insertion abnormality 3). If an illegal insertion of medals is detected, the process proceeds to step S805. If an illegal insertion of medals is not detected, the process ends.

  In step S805, a bit corresponding to error information D3 (selector signal) to be described later is turned ON among the bits of security status information stored in the RAM 313. In step S806, error information (this information is added to the error detection information provided in the RAM 313). In the example, information indicating medal insertion abnormality 3) is set.

  <Centralized terminal board signal setting processing>

  Next, the concentrated terminal board signal setting process (step S509) in the above-described timer interrupt process will be described with reference to FIG. This figure is a flowchart showing the flow of concentrated terminal board signal setting processing.

  In step S901, based on the on / off information of the door opening detection sensor 327 detected in the above-described input port monitoring process (step S502), error information D1 (door described later) is included in the bits of the security status information stored in the RAM 313. Signal) is set to ON or OFF.

  In step S902, among the security signals being transmitted (door signal, setting signal, selector signal, hopper signal, spare signal), a signal whose state has changed (ON at the start of signal transmission, A signal that is turned off during transmission or a signal that was turned off during transmission but turned on during transmission is then extracted.

  In step S903, among the bits of the security information change accumulation information stored in the RAM 313, the bit corresponding to the signal from which the state change is extracted in step S902 is set to ON, and the signal from which the state change is not extracted in step S902 Set the bit corresponding to to OFF.

  In step S904, it is determined whether it is the output bit switching timing, that is, whether the value of the signal output timer information stored in the RAM 313 has become zero. If it is not the output bit switching timing, the process proceeds to step S905. If the output bit switching timing is reached, the process proceeds to step S906.

  In step S 905, the number of bits to be output out of a total of 12 bits including 6 security bits and 6 blank bits described later is determined based on the remaining output bit count information stored in the RAM 313. A signal of a level corresponding to the determined bit (for example, a low level signal when the value stored in the bit is 0, and a high level signal when the value stored in the bit is 1) Output via 450 serial communication lines.

  In step S906, it is determined whether or not the remaining output bit count information stored in the RAM 313 is other than 0 (whether or not there are bits to be output among the 12 bits obtained by adding the security bit and the blank bit). . If the remaining output bit count information is other than 0 (when there are bits to be output), the process proceeds to step S907. If the remaining output bit count information is 0 (when there are no remaining bits to be output). Then, the process proceeds to step S913.

  In step S907, a value obtained by subtracting 1 from the value of the remaining output bit count information is stored in the remaining output bit count information.

  In step S908, a value corresponding to 20 ms is set in the signal output timer information provided in the RAM 313. In step S909, a bit corresponding to a start bit signal described later is turned ON among the bits of the security state information stored in the RAM 313. Set. In this embodiment, since the signal level of the start bit signal is fixed at a high level, instead of setting the bit corresponding to the start bit signal every time in step S909, the bit corresponding to the start bit signal is set only once. You may comprise so that it may set to ON.

  In step S910, the remaining output bit count information stored in the RAM 313 is acquired, and the position of the bit to be output next is acquired.

  In steps S911 and S912, the value of the security status information is stored in the security information, and is acquired in step 910 out of the bits of the security information in the storage area associated with the output port of the Main CPU (I / O mapped). A value stored in the bit position is written, and an on-level or off-level signal corresponding to the bit of the security information is output to the outside of the slot machine 100 via the serial signal line of the external concentration terminal board 450.

  In step S913, it is determined whether or not the state of the security signal has changed since the completion of the previous signal transmission based on whether or not the security information change accumulated information updated in step S903 is zero. If the security information change accumulation information is 0 (if the security signal state has not changed since the previous signal transmission was completed), the process proceeds to step S917. If the security information change accumulation information is other than 0 (previous signal transmission). If the status of the security signal has changed since completion), the process proceeds to step S914.

  In step S914, an exclusive OR (EXOR) of the security state information stored in the RAM 313 and the security information change accumulation information is calculated and stored in the security information. For example, when the value of the security status information is 40 (hexadecimal) and the value of the security information change accumulation information is 48 (hexadecimal), 08 (hexadecimal) is stored in the security information.

  In step S915, the security information change accumulation information area is cleared (set to 0), and in step S916, in order to continuously output a signal whose state has changed three times, 3 is set in the signal output remaining number information. Set. In this embodiment, since the state composite signal is output three times continuously when there is a change in the state of the error information D1 to D5, for example, for canceling the error state. When an error cancel button is provided, the pressing time for considering the error cancel button to be valid is set longer than the minimum time required to output the state composite signal three times in succession (720 ms in this embodiment). It is preferable.

  In step S917, the remaining signal output count information stored in the RAM 313 is referred to and it is determined whether the remaining signal output count information is other than 0 (whether there is a security signal to be output remaining). If the remaining signal output count information is other than 0 (when there is a security signal to be output), the process proceeds to step S918. If the remaining signal output count information is 0 (no security signal to be output remains). In the case), the process proceeds to step S922.

  In step S918, a value obtained by subtracting 1 from the signal output remaining number information value is stored in the signal output remaining number information. In step S919, an initial value (12 in this embodiment) is set as the remaining number of output bits.

  In step S920, a value corresponding to 20 ms is set in the signal output timer information provided in the RAM 313. In step S921, a bit corresponding to a start bit signal, which will be described later, is turned ON among bits of security state information stored in the RAM 313. Set.

  In step S922, an untransmitted level signal (low level in this embodiment) is output as a security signal.

  16 is a diagram schematically showing a storage area of the RAM 313 of the main control unit 300, and FIG. 17 is an explanatory diagram for explaining the contents of each information area shown in FIG.

  The RAM 313 of the main control unit 300 stores a security state information area for storing security state information, a security information change accumulation information area for storing security information change accumulation information, and a security for storing security signal information. A signal information area, a signal output timer information area for storing signal output timer information, an output bit remaining number information area for storing output bit remaining number information, and a signal for storing signal output remaining number information A remaining output count information area and a security signal output standby timer information area for storing security signal output standby timer information are provided.

  As shown in FIG. 17, the security status information consists of 1-byte data, and in order from the upper bit, a start bit signal (fixed to 1), error information D1 (door signal), error information D2 (setting signal), Error information D3 (selector signal), error information D4 (hopper signal), error information D5 (preliminary signal), unused (fixed to 0), and unused (fixed to 0) are allocated.

  The security information change accumulation information is composed of 1-byte data, and in order from the upper bit, is 1, whether there is a change in the state of error information D1 (door signal), whether there is a change in the state of error information D2 (setting signal), error information D3 (selector signal) state change presence / absence, error information D4 (hopper signal) state change presence / absence, error information D5 (preliminary signal) state change presence / absence, 0, 0 are assigned. As for the presence / absence of state change of the error information D1 to D5, 1 is stored when there is a state change in each error information, and 0 is stored when there is no state change.

  The security information has the same configuration as the security status information, and stores information on the signal currently output from the serial signal line of the external concentration terminal board 450.

  The signal output timer information is information for measuring the basic pulse width (20 ms in this embodiment) of the security signal. In this embodiment, every time the above-described timer interrupt processing is performed (about every 1.504 ms), 1 is added to the signal output timer information, so that a total of 13 counts are performed, and about 20 ms (= 1.504 ms × 13) Time is measured.

  The remaining number of output bits is information indicating how many unsent signals remain in one security signal, and includes 6 bits of security bits (start bit signal, door signal, setting signal, selector signal, hopper signal) 1) and subtract 1 each time a total of 12 bits of a 6-bit blank bit (stop bit signal, 0, 0, 0, 0, 0) are output. For example, when the remaining number of output bits is 12, it indicates that 12 bits of untransmitted signals remain, so after outputting the start bit signal, the number of remaining output bits is decremented by 1 to 11. Set. When the remaining number of output bits is 11, it indicates that 11 bits of untransmitted signals remain.

  For example, when it is detected by the (game) medal insertion sensor 320 that a (game) medal or the like has accumulated in the medal selector 170, information indicating the medal insertion abnormality 1 is set in the error detection information described above, and the number of games An error code “P00” is displayed on the display 126 to notify the outside that an error has occurred. Further, the medal insertion abnormality 1 is canceled by checking a game medal clogging of the medal selector 170 and then pressing a reset switch (not shown) or turning the door key 140 counterclockwise. In this embodiment, among these plural types of errors, medal insertion abnormalities 1 to 4, medal payout abnormalities 1 to 3, and overflow abnormality are output as a state composite signal (security signal), and output is output for RAM failure and display abnormality. Not performed.

  Next, the basic output pattern of the state composite signal will be described with reference to FIGS. 19 (a) and 19 (b). FIG. 4A is a time chart showing the basic output pattern of the state composite signal, and FIG. 2B shows the names and logics of the signals corresponding to the error information D1 to D5 included in the state composite signal. FIG.

  In the concentrated terminal board signal setting process described above, as shown in FIG. 5A, first, the state composite signal of the non-transmission level (low level in this example) is converted into the basic pulse width time (20 ms in this example). Only the signal is inverted to form a signal (start bit signal) of a start level (high level in this example). Next, five signals of ON level (high level in this example) or OFF level (low level in this example) corresponding to the time (20 ms) of the basic pulse width are formed as signals corresponding to the error information D1 to D5. . Finally, a signal of the same level as the untransmitted level (low level in this example) is held for the basic pulse width time (20 ms) to form a stop level signal (stop bit signal), and then the state composite signal is Set to the untransmitted level (low level in this example).

  In this embodiment, as shown in FIG. 5B, a door signal (door opening signal) is used as a signal corresponding to the error information D1, a setting signal (setting change signal) is used as a signal corresponding to the error information D2, and an error is generated. A selector signal (input error signal) is output as a signal corresponding to the information D3, a hopper signal (payout error signal) is output as a signal corresponding to the error information D4, and a spare signal is output in this order as a signal corresponding to the error information D5. .

  The door signal is a signal indicating whether the front door 102 is open or closed, and when the opening of the front door 102 is detected by the door open detection sensor 327 in the input port monitoring process (when an open signal is detected). ) Is set to the on level (for example, high level) in the concentrated terminal board signal setting process, and the door opening detection sensor 327 detects the closing of the front door 102 in the input port monitoring process (when the closing signal is detected). Further, it is set to an off level (for example, a low level) that can be distinguished from the on level in the concentrated terminal board signal setting process.

  The setting signal is a signal indicating whether or not the setting is being changed (or checking the setting value). At the start of the setting changing process (step S301 of the setting changing process) or at the start of checking the setting value (game) In step S403) of the medal insertion process, it is set to the on level, and is set to the off level at the end of the setting change process or at the end of the confirmation of the set value.

  The selector signal is a signal indicating whether or not the state of the medal selector 170 is abnormal, and when an abnormality of the medal selector 170 is detected by the medal insertion sensor 320 (for example, one of the medal insertion abnormalities 1 to 5 is detected). When the medal insertion sensor 320 does not detect an abnormality of the medal selector 170 (for example, when none of the medal insertion abnormalities 1 to 5 are detected) in the input port monitoring process. Set to off level.

  The hopper signal is a signal indicating whether or not the state of the hopper 172 is abnormal, and when an abnormality of the hopper 172 is detected by the medal payout sensor 326 (for example, when any of the medal payout abnormalities 1 to 3 is detected) ) And is set to the off level when no abnormality of the hopper 172 is detected by the medal payout sensor 326 (for example, when any of the medal payout abnormalities 1 to 3 is not detected).

  The spare signal is a signal to be used in a preliminary manner. In this embodiment, the spare signal is used as a start lever signal indicating that the start lever 135 has been received. Note that the spare signal can be used for other purposes, for example, a power signal, a settlement signal, and a reel non-stop signal. The power signal is a signal indicating whether or not the power of the slot machine 100 is on. When the voltage drop signal is off (when the power is on), the power signal is set to an on level, and the voltage drop signal is on. Set to off level (when power is off). The settlement signal is a signal indicating whether or not the settlement process is being performed, and is set to the on level when the settlement button 132 is pressed to start the settlement process, and is set to the off level at the end of the settlement process. The reel non-stop signal is a signal indicating that the reels 110 to 112 have not stopped for a predetermined time or more, and is set to an on level when the reels 110 to 112 have rotated for a predetermined time or more. When 112 stops, it is set to an off level.

  FIG. 20 is a time chart for explaining in more detail the basic output pattern of the state composite signal.

  The state composite signal can be divided into a security bit composed of a start bit and error information D1 to D5 and a blank bit composed of 0 information including a stop bit, and transmission of a security bit (transmission of a start bit signal) The time from the start) to the end of blank bit transmission is set to a fixed time (240 ms in this embodiment). Further, a signal composed of a start bit, error information D1 to D5, and a stop bit is collectively referred to as a security signal, and the transmission of the security signal (the transmission of the start bit signal starts) to the end of transmission of the security signal (transmission of the stop bit signal) ) Is set to a fixed time (140 ms in this embodiment). In this embodiment, among the security signals, the start bit signal and the door signal D1 are updated in the above-described timer interrupt processing, and the setting signal D2, the selector signal D3, and the hopper signal D4 are updated as described above. The signal state is updated in the main processing.

  FIG. 21 is a time chart when a state composite signal is continuously output a plurality of times, and FIG. 22 is a time when information on a medal insertion abnormality and a medal payout abnormality is continuously output a plurality of times as a state composite signal. It is a chart.

  As shown in FIG. 21, in the present embodiment, when the state composite signal is continuously output a plurality of times, after the state composite signal is output, it waits for a predetermined time (100 ms in this embodiment) to elapse. For example, when a medal insertion abnormality and a medal payout abnormality occur, a selector signal D3 corresponding to the medal insertion abnormality is generated as shown in FIG. After the composite signal with the hopper signal D4 corresponding to the medal payout abnormality set to the on level (high level in this example) is output once, after waiting for 100 ms after the stop bit signal is output, the same state Output a composite signal.

  FIG. 23 is a time chart of the state composite signal when the error state changes during the output of the state composite signal. In this example, error B occurs during the output of blank bits of the state composite signal indicating error state A. In this case, the security status information is updated from error A to error B in the main processing described above, and a status composite signal indicating error status B is output based on the updated security status information in the centralized terminal board signal setting processing described above. To do.

  FIG. 24 is a time chart showing the change of the hopper signal when the state of the medal payout abnormality changes during the output of the state composite signal. In this example, during the output of the state composite signal indicating the medal payout abnormality, the information on the medal payout abnormality changes several times from on to off to on to off to on. In this case, in the concentrated terminal board signal setting process described above, the change in the medal payout abnormality state (ON → OFF) is stored in the security information change accumulation information, and based on the stored security information change accumulation information. The next security status information is updated, and a status composite signal indicating no medal payout abnormality is output based on the updated security status information. In this example, the medal payout abnormality information is changed from off to on before the output of the state composite signal indicating that there is no medal payout abnormality. Therefore, in the above-described concentrated terminal board signal setting process, the change in the medal payout abnormality state (OFF → ON) is stored in the security information change accumulation information, and based on the stored security information change accumulation information. The next security status information is updated, and a status composite signal indicating a medal payout abnormality is output based on the updated security status information.

  FIG. 25 shows the flow of processing using medal insertion information, medal payout information, RB operation information, BB operation information, CB operation information, MB operation information, and security information during normal operation, power interruption, and power recovery. FIG.

  The slot machine 100 normally outputs security information (error information D1 to D5) using a serial signal line, as well as medal insertion information, medal payout information, RB operation information, BB operation information, CB operation information, and MB operation. Each piece of information is individually output using six parallel signal lines.

  FIG. 26 is a time chart showing an example of a medal insertion signal and a medal payout signal. The medal insertion signal is a signal indicating the number of inserted medals, and when the operation of the start lever 135 is accepted, the basic minimum is the number corresponding to the number of medal insertions stored in the medal insertion information (three in this example). An on-level (high level in this example) signal having a pulse width (50 ms in this example) is output. The medal payout signal is a signal indicating the payout number of medals. When all the reels 110 to 112 are stopped, the basic minimum pulse is the number of times corresponding to the medal payout number (three in this example) stored in the medal payout information. An on-level (high level in this example) signal having a width (50 ms in this example) is output. When a re-game is won, a medal payout signal is output assuming that there is a payout number corresponding to the number of inserted medals.

  FIG. 27 is a time chart showing an example of the BB signal and the RB signal. The BB signal is a signal indicating the operation of the BB game. When all the reels 110 to 112 are stopped and the symbol combinations corresponding to the BB game are prepared, the BB game is started at the start of the next game (BB operation). When the information is turned on), an on-level signal (high level in this example) is output, and although not shown, when the BB game is finished (when the BB operation information is set to off) Outputs an off-level (low-level) signal. The RB signal is a signal indicating the operation of the RB game. When all the reels 110 to 112 are stopped and the symbol combinations corresponding to the RB game are prepared, the RB game is started at the start of the next game (RB operation). When the information is turned on), an on-level signal (high level in this example) is output, and although not shown, when the RB game is finished (when RB operation information is set to off) Outputs an off-level (low-level) signal. Since the slot machine 100 according to the present embodiment does not employ CB games and MB games, description of the CB signals and MB signals is omitted. However, when CB games and MB games are employed, BB signals and MB games are omitted. Output is performed in the same manner as the RB signal.

  In the first embodiment, information having a high frequency of state change, such as the number of inserted medals, the number of paid out medals, and the game status, is output as parallel signals, and the number of inserted medals, the number of paid out medals, and the game Information such as the opening / closing of the front door 102, the occurrence of an abnormality in the hopper 172, the occurrence of an abnormality in the medal selector 170 is output as a serial signal, which has a lower frequency of state change than the state. Therefore, the number of serial signal on / off switching operations can be reduced compared to the number of parallel signal on / off switching operations, and a relay 454b (described later) having a mechanical switch is arranged on the serial signal transmission path. Even if it is provided, the ON / OFF count of the relay 454b does not increase more than necessary, and the durability of the relay 454b can be improved.

  Returning to FIG. 25, the slot machine 100 stores each information of medal insertion information, medal payout information, RB operation information, BB operation information, CB operation information, and MB operation information in the first identification of the RAM 313 during power interruption. The security information is stored in the power failure state information of the second specific area of the RAM 313 while being saved in the power failure state information of the region. Further, at the time of power recovery, medal insertion information, medal payout information, RB operation information, BB operation information, CB operation information, and MB operation information are stored in the power recovery state information in the first specific area of the RAM 313. The security information is stored in the power recovery status information in the second specific area of the RAM 313. Further, at the time of power recovery, based on the power failure state information of the first specific area of the RAM 313 and the power failure state information of the first specific area (the power failure state information of the first specific area and the first specific area A parallel signal is generated by calculating a logical sum of the power recovery status information) and based on the power failure status information of the second specific area of the RAM 313 and the power recovery status information of the second specific area (second specific A state composite signal (serial signal) is generated by calculating the logical sum of the region power failure state information and the power recovery state information of the second specific region, and these parallel signals and serial signals are externally concentrated as external output information. Output from the terminal board 450.

  FIG. 28 is a time chart showing a security signal, error display on / off timing, and error release timing when medal insertion abnormalities 2 to 4 or medal payout abnormality 3 occur. For example, when the medal payout abnormality 3 is detected during the rotation of the reels 110 to 112, an on-level (high level in this example) signal is output as the hopper signal D4 at the error detection position in the figure, and the medal When the medal insertion ready state becomes possible, error display is performed using the game number display 126 at the error notification position in the figure (the error display is turned on). If an error cancel operation is performed, the error display is erased (error display is turned off).

  FIG. 29 is a time chart showing a security signal, error display on / off timing, and error release timing when the medal insertion abnormality 2 to 4 or the medal payout abnormality 3 occurs during the setting change. For example, when the medal payout abnormality 3 is detected during the setting change, an on-level (high level in this example) signal is output as the hopper signal D4 at the error detection position in the figure. Since there is a high possibility that the medal payout abnormality 3 is erroneously detected by touching a device such as the hopper 172 while changing the setting, no error display is performed.

  As described above, the slot machine 100 according to the present embodiment includes a control unit (main control unit in this embodiment) 300 that includes a CPU 310 that controls a game, and a game information signal (this embodiment) output from the control unit 300. In the example, a signal output means (in this embodiment, an external concentration terminal board) 450 that outputs a state composite signal (security signal)) to the outside of the gaming table, and a plurality of status information (in this embodiment, an error in this embodiment) A state information generating means for generating information D1 to D5), and a serial signal is generated based on at least one state information among a plurality of state information generated by the state information generating means, and this serial signal is used as a game information signal. A game table provided with game information output means (mainly corresponding to the concentrated terminal board signal setting processing in this embodiment) to be output from the signal output means 450, The state information includes fraud information (in this embodiment, information on illegally inserting medals, information on illegally paying out medals, etc.) indicating that an illegal act has been performed on the game machine. It is a game table.

  According to the gaming machine according to the present invention, it is possible to output information on fraud detected on the gaming machine side to the external device without significantly changing the conventional hardware configuration, which is difficult to deal with in the conventional gaming machine. It is possible to take some measures against clever fraud that was.

  In addition, when the game information output means detects that the state of the cheating information has changed, the game information signal including the cheating information after the change is continuously received from the signal output means a plurality of times (three times in this embodiment). If it is output in this manner, the possibility that the external device will miss the game information signal can be reduced, and information related to the fraudulent activity detected on the game stand side can be transmitted to the external device more reliably.

  The game information signal includes a start bit signal indicating the start of the game information signal and a stop bit signal indicating the end of the game information signal. The game information output means outputs the stop signal of the first game information signal. If it is configured to output a start signal of the second game information signal following the first game information signal after waiting for a predetermined time (100 ms in this embodiment) to elapse, A sufficient margin can be ensured between one game information signal and the second game information signal, and it is possible to prevent a problem that the external device misses the second game information signal. Become. It is also possible to finely adjust the transmission interval of the game information signal in accordance with the reception environment of the external device connected to the game machine.

A signal transmission circuit 454 having a mechanical contact for transmitting the gaming information signal to the signal output circuit 456, because the game information signal is transmitted through the mechanical contact, noise, etc. Highly accurate information can be output to an external device.

  Also, different priority levels are added in advance to the plurality of status information, and if the game information output means outputs the status information in descending order of priority, the external device receives the information with the higher priority level first and receives the received information. Measures can be quickly implemented, for example, if information on fraud is received as high-priority information, measures against fraud can be promptly implemented. Damage can be minimized.

  The configuration of the gaming machine according to the present invention is not limited to the configuration shown in the above embodiment. For example, in the above embodiment, the time of 20 ms, which is the minimum pulse width of the serial signal, is set to 13 timer interrupts. However, other methods may be used.

  Moreover, although the example which performs a concentrated terminal board signal setting process whenever it starts a timer interruption process was shown, it is not limited to this, For example, it is a concentrated terminal board signal only once while starting a predetermined number of times of timer interruption processes.

  In addition, an example is given in which information with a high occurrence frequency (or change frequency) is output from a parallel signal line, and information with a low occurrence frequency (or change frequency) is output from a single serial signal line. Instead, what information is output through the parallel signal line and what information is output as the serial signal may be determined as appropriate.

  Further, a plurality of signal lines for transmitting the state composite signal may be provided. That is, one or a plurality of signal lines (for example, a medal insertion signal to an external signal 4) for transmitting one type of information, and one or a plurality of single signal lines (for example, a state composite signal) for transmitting a plurality of types of information. In addition, they may be included in a single signal transmission member constituted by a pair of connectors and a set of signal lines, and a predetermined section (for example, between boards) is electrically connected by the signal transmission member. You may comprise.

  In addition, the game stand according to the present invention is provided with “a plurality of reels provided with a plurality of types of symbols, a start lever for starting the rotation of the reels, and a reel corresponding to each reel.
