When a ball is won at the starting port 21 and a winning ball is detected by the starting port switch 121, the right of display game in the variable display device 310 is acquired and the display game is executed.

  The plurality of types of identification information variably displayed on the variable display unit 311 are pre-determined for each type, and as shown in FIG. 14 (a), the Chinese numerals "1" to "ten" are adopted. Has been. Here, a number obtained by subtracting 1 from a Chinese numeral as identification information is determined as an actual identifier (number) of each identification information. For example, the identification information “one” corresponds to the number 0 as an identifier. “2” corresponds to the number 1 as an identifier, and identification information “10” corresponds to the number 9 as an identifier.

  In addition, for example, to make it easy to understand the correspondence between the identification information and the identifier, the Chinese numerals “zero” to “nine” may be adopted, and the meaning numbers may be set as the identifiers as they are. However, in the present embodiment, the above-described example is adopted with the intention of adding some difficulty when determining whether or not a specific condition described later is satisfied. Of course, the identification information is not limited to a pattern using a Chinese numeral as a motif, and other information imitating a character, various characters, figures, symbols, or a combination thereof may be adopted.

  A plurality of types of items that are sequentially displayed on the item display unit 312 are prepared, and each form is predetermined for each type. As shown in FIG. 14B, a square origami having a different color and pattern is simulated. The design which was made is adopted. Here, an identifier (number) is determined for each type of origami as an item. For example, “red” corresponds to number 1 as an identifier, “blue” corresponds to number 2 as an identifier, and “gold” "Corresponds to the number 6 as an identifier. Such an item is not limited to a pattern using a square origami as a motif, and other items imitating a character, various characters, figures, symbols, or a combination thereof may be adopted.

  In the display game in the present embodiment, as shown in FIG. 15, the display area of the variable display device 310 is divided into a left display location 311a, a right display location 311b, and a central display location 311c arranged in three horizontal rows. A plurality of types of identification information are variably displayed so as to scroll in the vertical direction for each of the display locations 311a to 311c. Then, after the predetermined time has elapsed, the arbitrary display information is set to stop one by one for each of the display locations 311a to 311c in the order of the left display location 311a, the right display location 311b, and the central display location 311c. ing. Each of the display locations 311a to 311c imitates one reel in the slot machine, and a display game is developed as a whole as a symbol matching game in the slot machine.

  As a result of execution of the display game, the symbols stopped at the respective display locations 311a to 311c are set in a predetermined combination (for example, a state in which all three, such as “5, 5, 5”, etc., are all aligned) The case where it becomes is defined as a “specific display mode”. Before such specific display mode is determined, a state in which the stopped symbols coincide with the other two display locations 311a and 311b except for the last display location 311c corresponds to the “reach mode”. That is, the reach mode is a display mode that forms part of a predetermined combination of identification information corresponding to the specific display mode when there is a possibility of deriving the specific display mode in a display game.

  The items displayed on the item display unit 312 are continuously displayed regardless of whether or not the display game is being played. Any one of a plurality of types of items is automatically given to the player at a predetermined timing in the game, and sequentially displayed on the item display unit 312. For example, the items given to the player may be set so as to be selected at random on the gaming machine side.

  An upper limit is set for the number of items that can be acquired by the player, and in the present embodiment, up to seven items (see FIG. 13) so as to match the number of individual display fields constituting the item display unit 312. It has been established. When a new item is given beyond this upper limit value, the item is deleted in order from the oldest acquisition time. Specifically, in each display field constituting the item display unit 312, a newly assigned item is added to the leftmost display field, and existing items are moved to the right display field one by one. Then, the item in the rightmost display column disappears from the display area and is deleted.

  Items that the player has already acquired are temporarily stopped when the display mode that is disadvantageous to the player is derived during the display game, and is temporarily displayed to constitute the disadvantageous display mode. Any of the identification information has the effect of re-variation. The item exercised here also disappears from the display area and is deleted. When the number of items displayed on the item display unit 312 is less than the upper limit, the items are displayed on the item display unit 312 in a left-justified manner as shown in FIG. Yes.

  When an item is exercised, if the item satisfies a specific condition with respect to the re-changed identification information, as a result of re-change, the display mode shifts from the disadvantageous display mode to a player-friendly display mode. . In the present embodiment, it is set so that items already acquired by the player are exercised in the order of their acquisition time. Details on acquisition and exercise of items, and re-variation and transition of display modes based on the results will be described later.

  When the execution result of the display game is finally determined in the specific display mode, a special game state in which a special winning opening 24 described later is repeatedly opened and closed a predetermined number of times can be generated. Moreover, when the execution result of the said display game is not finally settled in the said specific display mode, it corresponds to a discontinuous display mode.

  Further, when the execution results of the display game are arranged in a predetermined probability variation pattern (for example, “seven” of identification information) in the specific display mode, a special game state corresponding to a so-called probability variation big hit occurs. When the probability change jackpot occurs, the probability that the specific display mode is determined in the next display game after the special game state is ended is higher than that in the normal game state. Thus, a gaming state in which the probability that a special gaming state will occur compared to the normal time is called a probability variation state (or “probability variation mode”).

  When a ball is won at the starting port 21 during execution of the display game or during the occurrence of a special game state to be described later, the right to execute the display game is acquired, but the display that is currently in progress is put on hold. After the game is over, the rights that have been put on hold are gradually digested. Here, the number of reserved balls of the display game is set to a maximum of four, and the number is notified by the special symbol hold LED 420.

  The large winning opening 24 is generally called an attacker, and the door is variably operated by the operation of a drive source such as a solenoid (large winning opening solenoid 134, direction switching solenoid 135), and the winning opening is a ball. It is configured to be able to change between a normal closed state that is difficult to win and an open state that is easy to win.

  The special prize opening solenoid 134 operates to open and close the door of the special prize opening 24 a predetermined number of times (for example, 15 times) when the special gaming state is established. The direction switching solenoid 135 operates the passage member so as to guide the winning ball to the accessory continuous actuating device switch 124 side in a state where the door of the big winning opening 24 is opened. When a winning ball is detected, the next operation is to guide the winning ball to the count switch 125 side.

  That is, the special winning opening 24 is controlled to be opened and closed so as to produce a special gaming state when the display game is in a specific display mode. Here, the special game state is a state in which an opening / closing operation of maintaining the open state for a predetermined time and then returning to the closed state for a short time is repeatedly executed up to a predetermined number of rounds (for example, 15 times). When a predetermined number of balls (for example, 10) wins the big winning opening 24 or when a predetermined time (about 30 seconds) elapses, the door of the big winning opening 24 is closed. And when a series of operation | movement is complete | finished by the said predetermined number of times, the said special game state will be complete | finished.

  The normal symbol display device 140 performs variable display by lighting two LED lights divided into left and right. In other methods than the two LED lights, a 7-segment display may be used. The right and left LEDs are assigned to “win” and “off”, respectively. When the right and left normal symbol display device operation gate switches 126a and 126b detect passage of a sphere, the normal symbol display device 140 uses the normal symbol display device 140 for the normal symbol game. Acquire rights and play regular symbol games.

  In the normal symbol game, variable display is started by alternately flashing the left and right LEDs of the normal symbol display device 140. When the variable display is performed for a predetermined time and stopped, either the left or right lighting is displayed, and the player visually checks the determination result. Can be confirmed. If the result of the determination is “winning”, each movable piece of the starting port 21 is temporarily operated from a normal closed state where the ball is difficult to win to an open state where the ball is easy to win.

  If the passing symbol is detected by the left and right normal symbol display device operation gate switches 126a and 126b while the normal symbol display device 140 is variably displayed, the right of the normal symbol game is acquired but is put on hold and is currently in progress. After the normal symbol game is consumed, the reserved rights are sequentially consumed. The number of balls held in the normal symbol game is set to a maximum of four and is notified by the normal symbol hold LED 421.

Next, various control boards used for controlling the gaming machine main body 1 will be described.
5 and 6 are block diagrams showing various control boards used for controlling the gaming machine main body 1 and components related thereto. 5 and 6 show a main board 100, a payout control board 200, a display control board 300, a lamp control board 400, a sound control board 500, a launch control board 600, and a power supply board 700 as control boards. .

  Here, the main board 100 and the display control board 300 are means for controlling the display of the variable display device 310 and controlling the operations of various accessories. Specifically, for example, an item giving means and an item exercising means. And a display mode transition unit and a reach mode deriving unit.

  The item providing means is a means for performing control to give any of a plurality of types of items for re-changing the identification information temporarily stopped and displayed during the display game to the player at a predetermined timing in the game. When the reach mode is derived in the display game but the specific display mode is not confirmed, the item granting unit grants the item to the player at the timing.

  The item assigning means randomly selects one of a plurality of types of items and automatically assigns it to the player. As described above, the item assigning means sets an upper limit on the number of items that can be acquired by the player, and deletes the items in order from the oldest acquisition time when giving a new item to the player beyond the upper limit.

  The item exercising means is temporarily stopped and displayed to constitute the disadvantageous display mode by exercising the item already acquired by the player when a disadvantageous display mode for the player is derived during the display game. This is means for performing display control for re-changing any of the identification information.

  The item exercising means is that when the reach mode can be derived in the display game, if the reach mode is not derived and a disadvantageous display mode is derived for the player, the player has already acquired at that timing. By exercising the existing item, any of the temporarily stopped identification information constituting the disadvantageous display mode is changed again.

  The item exercising means automatically exercises the items that the player has already acquired in order from the oldest acquisition time. Furthermore, the item exercising means deletes the exercised item when the player has exercised the item already acquired.

  The display mode transition means shifts from the disadvantageous display mode to a player's advantageous display mode as a result of the re-change when the exercised item satisfies a specific condition for the re-changed identification information. This is means for performing display control. The display mode transition means shifts the unfavorable display mode to the reach mode as a result of the re-change when the exercised item satisfies a specific condition for the re-changed identification information.

  Reach mode deriving means, when there is a possibility of deriving a specific display mode in the display game, the reach mode forming a part of a predetermined combination of identification information corresponding to the specific display mode is changed to the specific display mode. This is a means for performing display control derived in the previous stage of determination.

FIG. 6 shows details of the main board 100.
The main board 100 operates based on the clock generated by the clock circuit 108 inside the main board. In addition, by inputting an interrupt signal at regular time intervals obtained by dividing the clock generated by the clock circuit 108 by the internal timer 107 to the CPU 102, the CPU 102 executes timer interrupt processing at regular time intervals. The CPU 102 performs a series of operations by executing, for each interrupt, a process divided so as to end in a time shorter than the interval of the timer setting time.

  Start opening switch 121, right normal symbol display device operation gate switch 126a, left normal symbol display device operation gate switch 126b, right sleeve winning port switch 122a, left sleeve winning port switch 122b, right dropping winning port switch 123a, left dropping winning port Each of the switches 123b is a switch for detecting a winning of a ball, and input signals from these switches are supplied to the gate circuit 110.

  Each input signal from the accessory continuous operation device switch 124, the count switch 125, the right prize ball detection switch 130a, the left prize ball detection switch 130b, the shot ball break switch 131, the glass frame open detection switch 132, and the overflow switch 133 is a gate. This is supplied to the circuit 111.

  The addresses of the gate circuits 110 and 111 are set in the address space of the CPU 102 by the memory mapped I / O method. The address selection circuit 113 decodes the address signal and the write / read control signal output from the CPU 102 in accordance with the system clock output from the CPU 102 to generate a chip select signal.

  When the gate circuits 110 and 111 are selected by this chip select signal, each input signal from the start port switch 121 or the like is output to the data bus through the gate circuit. Each input signal on the data bus is detected multiple times by the interrupt signal generated at regular intervals until the next interrupt processing is executed and chattering prevention processing is performed, then specified for each input signal Stored in the RAM area.

  The input signal from the start port switch 121 is a five-point ball signal, and is input from the right sleeve winning port switch 122a, the left sleeve winning port switch 122b, the right dropping winning port switch 123a, and the left dropping winning port switch 123b. Each signal is treated as a prize ball signal for eight prize balls, and further, an input signal from the accessory continuous actuator switch 124 and the count switch 125 is treated as a prize ball signal for 15 prize balls. The number is stored in the designated RAM area. At the same time, the total number of prize balls is calculated by the CPU 102 and stored in a designated RAM area.

  In addition, random numbers are respectively set for input signals from the start port switch 121, the right normal symbol display device operation gate switch 126a, and the left normal symbol display device operation gate switch 126b, and these values are stored in the RAM area. . Based on this data, the gaming state of the gaming machine body 1 is set and the data is output to each control board.

  Output data to each control board passes through a buffer 114 provided in the middle of the data bus, and is further output to the latch circuits 112a to 112g through the output data bus. By arranging the buffer 114 in the middle of the data bus connecting the output latch circuit and the CPU 102, the bus signal flows in one direction, which is a countermeasure against fraud.

  There are data in the starting ball switch 5 prize ball RAM area, left and right sleeve winning prize switch, left and right drop prize opening switch 8 prize ball RAM area, accessory continuous actuator switch, 15 count switch prize ball RAM area, The CPU 102 sequentially outputs 8-bit prize ball data set for each prize ball number to the latch circuit 112a through the data bus and the output data bus. In synchronization with this, an interrupt signal for the payout control board 200 and a control signal for the strobe signal are output to the latch circuit 112e through the data bus and the output data bus.

  When the chip select signal obtained by decoding by the address decoding circuit 113 controlled by the memory mapped I / O is sequentially output to the latch circuit 112a and the latch circuit 112e, the 8-bit prize ball data is interrupted to the latch circuit 112a. The control signal of the signal and the strobe signal is latched by the latch circuit 112e, and the output signal composed of the 8-bit parallel award ball output signal, the interrupt signal, and the 2-bit control signal of the strobe signal is sent to the payout control board as the award ball data. Is output as

  The payout control board 200 shown in FIG. 7 controls the ball discharge mechanism to discharge the number of prize balls corresponding to the prize ball data. The discharged prize ball is detected by the right prize ball detection switch 130a and the left prize ball detection switch 130b, and the detection signal is output to the gate circuit 211. As the chip select signal is output from the address decoding circuit 213 to the gate circuit 211, the detection signals output from the right winning ball detection switch 130a and the left winning ball detection switch 130b are output onto the data bus and taken into the CPU 102.

  Based on these detection signals, the number of prize balls actually paid out is calculated by the CPU 102, the value is subtracted from the stored data in the RAM area, and the data of the number of prize balls is updated in real time. An output signal is output to the latch circuit 112f for each set number of winning prize balls, and is output to the outside in synchronization with the chip select signal of the address decode circuit 113.

  Random values are acquired for the input signals of the start port switch 121, the right normal symbol display device operation gate switch 126a, and the left normal symbol display device operation gate switch 126b, respectively, and based on this, the CPU 102 determines the type of game effect (control pattern). ) Is determined, and game state effect data is generated and stored in the RAM area.

  Further, the display control board 300 outputs data related to the display mode and identification information corresponding to the gaming state effect data as display effect data in time series. That is, when the 8-bit recognition code and the display state presentation 8-bit data are sequentially output from the CPU 102 to the latch circuit 112b through the data bus, an interrupt signal to the display control board 300 and each strobe signal are synchronized with them. A 2-bit control signal is output to the latch circuit 112e.

  These signals are sequentially latched by the latch circuit and output in parallel at the timing based on the chip select signal that is decoded and output from the address decoding circuit 113 controlled by the memory mapped I / O. Data relating to the identification information, variation stop data, and the like are sequentially output to the display control board 300 as display effect data.

  In synchronization with the display effect data, 8-bit parallel lamp display output data and a control signal are output to the lamp control board 400 through the latch circuit 112c. In synchronization with the display effect data, the 8-bit parallel sound source output data and the control signal are output to the audio control board 500 through the latch circuit 112d. That is, the chip select signal is output from the address decode circuit in synchronization with the timing at which each data is output to the data bus, the data on the data bus is latched by the latch circuits 112c and 112d, and output to the lamp control board 400 or the like. Is done.

  When the gaming state is the special gaming state (big hit), the control data of the big prize opening solenoid 134 is output to the latch circuit 112g in synchronization with the gaming state effect data, and the chip select signal from the address decoding circuit 113 is the latch circuit 112g. Is input. As a result, the control data of the special prize opening solenoid 134 is output from the latch circuit 112g, the special prize opening solenoid 134 is driven, the special prize opening 24 is opened and closed, and the ball can be guided to the special prize opening 24.

  When the accessory continuous actuating device switch 124 arranged in a specific area inside the big prize opening 24 detects a ball, a ball detection signal is output, and this signal is output to the data bus via the gate circuit 111 and taken into the CPU 102. As a result of the detection process based on the ball detection signal output from the accessory continuous actuator switch 124, the control data of the direction switching solenoid 135 is output to the latch circuit 112g, and the direction switching solenoid 135 is braked. At the same time, round continuation data indicating whether or not to continue the jackpot state to the next round is stored in the RAM area based on the ball detection signal output from the accessory continuous operation device switch 124.

  When the direction switching solenoid 135 is braked, the ball is counted by the count switch 125 disposed in the special winning opening 24. When the total count of the data counted by the count switch 125 reaches a predetermined quantity, the output data of the latch circuit 112g is changed, and the big prize opening solenoid 134 and the direction switching solenoid 135 become inactive, and one big hit round Ends. When the round continuation data indicates the continuation of the round after a predetermined time, the big hit state round is further continued by the control method described above.

  Random numbers are acquired for the input signals from the right normal symbol display device operation gate switch 126a and the left normal symbol display device operation gate switch 126b, respectively. Based on this random number value, display control data of the normal symbol display device 140 (normal symbol LED1, normal symbol LED2) is generated and output from the CPU 102 to the latch circuit 112g through the data bus. Each time a chip select signal is output from the address decode circuit 113, normal symbol LED display is performed for a certain period of time.

  When the result of obtaining the random number is correct, braking data of the ordinary electric accessory solenoid 136 that operates each movable piece of the start port 21 is output from the CPU 102 to the latch circuit 112g and also from the address decode circuit 113. Is output from the latch circuit 112g for a predetermined time in response to the chip select signal, and the ordinary electric accessory solenoid 136 is controlled. As a result, a state occurs in which the ball is likely to win the start opening 21 on the game board 2.

  When power is supplied to the main board 100, a reset signal is supplied from the power board 700 and each device on the main board 100 is reset. Thereafter, the system reset signal becomes inactive, and each device transitions to the active state. When the system reset signal changes to an inactive state, the reset signal to the one-chip microcomputer 101 becomes inactive after a predetermined time has elapsed due to clock synchronization and delay processing by the delay circuit 109. As a result, the one-chip microcomputer 101 enters an operating state, and the operating state of the main board 100 is maintained. Thereafter, initial setting of the one-chip microcomputer 101 is performed.

  When the power supply externally supplied from the gaming machine is unstable, a power failure detection signal is supplied from the power supply board 700 to the NMI (non-maskable interrupt) 105 of the one-chip microcomputer 101, and the one-chip microcomputer 101 performs a save operation for each storage area. Done.

  Specifically, after detecting the winning ball detection data for a certain period of time, the power failure processing determination data is stored in the RAM area to protect the RAM 104. That is, as the power supply voltage decreases, the backup power supply DC5VBB is supplied from the power supply board 700 to the RAM 104, and the storage state of the RAM 104 is maintained.

  When the power is next supplied, the one-chip microcomputer 101 performs a power failure recovery process upon recognizing that there has been a power failure process based on the presence or absence of the power failure process determination data. If the RAM initialization signal is active at the time of initialization, the CPU 102 detects data of the I / O port 106 and initializes the RAM area.

  A signal for detecting the ball breakage by the shot ball break switch 131 and a signal for detecting the ball clogging of the prize ball in the lower plate of the game board surface by the overflow switch 133 are taken into the one-chip microcomputer 101 through the gate circuit 111 and the data bus. . After data conversion, these signals are output from the latch circuit 112a to the payout control board 200 with the same configuration as the prize ball output data. The outputs of the latch circuits 112a to 112g are unidirectional and take an irreversible output form.

  The main board 100 operates based on the clock generated by the clock circuit 108 inside the main board. The internal timer 107 generates an interrupt signal to the CPU 102 at regular time intervals by a frequency dividing operation. The CPU 102 performs various processes at regular intervals when the interrupt signal is input.

Next, the payout control board 200 shown in FIG. 7 will be described.
The payout control board 200 performs one-way communication only from the main board 100 and receives communication data composed of 8-bit parallel prize ball data, prize ball data control signal 1, and prize ball data control signal 2.

  When the winning ball data control signal 1 is input to the counter circuit 202 of the one-chip microcomputer 201, an interrupt signal is output from the counter circuit 202 to the CPU 203. As a result, the prize ball data control signal 1 triggers the CPU 203 to fetch prize ball data.

  The CPU 203 outputs a chip select signal to the gate circuit 212 and the gate circuit 211 through the address decoding circuit 213, and takes in the prize ball data and various signals input to the gate circuits 212 and 211 via the gate circuit and the data bus. And stored in the RAM 205. Then, the payout operation is sequentially performed with the number of winning balls corresponding to the received winning ball data.

  The CPU 203 outputs a winning ball path switching signal to the latch circuit 215 through the data bus, and at the same time, outputs a chip select signal from the address decoding circuit 213. As a result, a prize ball path switching signal is output to the solenoid 224, and a prize ball path is secured for the payout operation. Thereafter, a stop release signal of the payout stop solenoid signal is output to the latch circuit 214, the payout motor control signals 1, 2, 3, 4 are sequentially output to the payout motor 222, and the motor rotation is controlled by the output timing of the chip select signal. While performing the prize ball payout operation.

  Based on the clock of the clock circuit 209, an internal timer 208 generates an interrupt signal at regular time intervals to the CPU 203. At this interrupt timing, the detection signal of the winning ball payout ball is taken into the data bus, and a predetermined number of winning balls is obtained. When detected, the driving of the payout stop solenoid 223 and the payout motor 222 is stopped. The detection of the winning ball payout ball is performed by the right award ball detection switch 130a and the left award ball detection switch 130b installed in the ball lending path, and these detection signals output a chip select signal to the gate circuit 211. Is taken into the data bus.

  The ball lending operation is performed by transmitting / receiving a ball lending signal to / from the card unit (CR ball lending machine) b through the gate circuit 211 and the latch circuit 215. During the ball lending operation, the CPU 203 outputs a ball lending route switching signal to the route switching solenoid 224 through the latch circuit 215 to secure the ball lending route, and the right lending ball detection switch 220a installed on the ball lending route detects the left lending ball. The switch 220b detects the rented ball and performs a payout operation.

  In the ball lending operation, information is output from the latch circuit 215 to the outside every fixed number. Further, in a state where the transmission / reception of the ball lending signal is normal, a firing permission signal is output from the latch circuit 215 to the firing control board 600 in an active state. When an abnormality occurs in the transmission / reception of the ball lending signal, the launch permission signal changes to an inactive state, and the ball cannot be launched. However, when the ball lending signal transmission / reception returns to a normal state, the ball lending signal can be launched.

  In addition, in the payout operation, the main board 100 transmits the shot ball cut signal of the shot ball cut switch 131 and the overflow signal of the overflow switch 133 installed in the lower tray 4 of the gaming machine body 1 to the winning ball data. Then, the payout control board 200 stops the payout operation. In addition, the payout operation is resumed when each release signal is transmitted to the award ball data.

  When power is supplied to the payout control board 200, a system reset signal is supplied from the power supply board 700, and each device on the payout control board 200 is reset. Thereafter, the reset signal is inactive, and each device transitions to the active state.

  Due to the delay processing of the clock synchronization / delay circuit 210, the reset signal to the one-chip microcomputer 201 becomes inactive after a lapse of a fixed time after the original reset signal changes to the inactive state. Thus, the one-chip microcomputer 201 is in an operating state after a predetermined time has elapsed since the original reset signal became inactive, and the operating state of the payout control board 200 is maintained. Thereafter, initial setting of the one-chip microcomputer 201 is performed.

  When the power supply externally supplied to the gaming machine is unstable, a power failure detection signal is supplied from the power supply board 700 to the NMI (non-maskable interrupt) 206 of the one-chip microcomputer 201, and the one-chip microcomputer 201 performs a save operation of each storage area. Done. Specifically, after detecting the winning ball detection data for a certain period of time, the power failure processing determination data is stored in the RAM area to protect the RAM 205.

  When the power supply voltage decreases, DC5VBB is supplied from the power supply board 700 to the RAM 205 as a backup power supply, and the storage state of the RAM 205 is maintained. When power is supplied again, the one-chip microcomputer 201 performs a power failure recovery process by recognizing the presence of the power failure processing determination data. If the RAM initialization signal is active at the time of initialization, the CPU 203 detects the data of the I / O port 106 and initializes the RAM area.

  The voice control CPU 501 receives instruction information from the main board 100 through parallel communication via the input / output interface 506. The voice control CPU 501 executes the contents of the input instruction information in accordance with the voice control procedure stored in the voice control ROM 502 and organizes and stores the information in the voice control RAM 503 while giving specific instructions to the voice control IC 504. Do.

  The audio control IC 504 generates a specific audio signal by referring to the audio data ROM 505 in accordance with an instruction from the audio control CPU 501, and outputs it to the amplifier circuit 507. When the power to the pachinko machine is turned on, the reset signal from the power board is input from the power board 700 to the voice control CPU 501, and the voice control CPU 501 follows the voice control procedure stored in the voice control ROM 503. Each control circuit in 500 is initialized.

Next, the launch control board 600 shown in FIG. 11 will be described.
The firing control board 600 includes an oscillation circuit 601 that is a circuit for generating a pulse for setting the rotational speed of the pulse motor used for the firing motor 653 to a predetermined rotational speed, a frequency dividing circuit 602, and a handle unit 650. Motor drive signal control that determines a signal from the touch sensor 651, a signal from the stop switch 652, a reset signal from the power supply board 700, and a firing permission signal from the payout control board 200, and generates a firing motor drive signal. A circuit 603 and a driver circuit 604 for exciting each coil of a pulse motor (firing motor 653) are configured.

  The handle portion 650 includes a touch sensor 651 for detecting whether or not the player is touching the handle 5, a stop switch 652 for allowing the player to arbitrarily stop the ball, and a pulse motor for firing the ball. It is comprised by 653 (launch motor) etc. The reset signal from the power supply board 700 is input from the power supply board 700 to the motor drive signal control circuit 603 when the gaming machine body 1 is turned on, and initializes each circuit of the launch control board 600.

  The touch sensor 651 in the handle portion 650 outputs a signal that the player can touch if the player is touching the handle 5, and fires if the player is not touching the handle 5. Are output to the motor drive signal control circuit 603, respectively.

  The stop switch 652 is a switch provided so that the player can arbitrarily stop the launch of the ball. When the stop switch 652 is operated by the player, the motor drive signal control circuit 603 receives the ball. A firing stop signal is output, and when the stop switch 652 is not input, a ball firing signal is output.

  Further, the stop switch 652 outputs the same signal as that input from the stop switch 652 when there is no operation on the stop switch 652 by the player and the handle 5 is not rotated. That is, due to the structure inside the handle 5, the signal from the stop switch 652 is input when the handle 5 is not rotating. That is, power is turned on to the gaming machine main body 1, the reset signal is input to the motor drive signal control circuit 603, and after each circuit is initialized, the player touches the handle 5 to rotate it. Only then will the ball be fired.

Next, the power supply substrate 700 shown in FIG. 12 will be described.
The AC 24V supplied from the outside is subjected to full-wave rectification with a diode bridge rectifier to generate a DC power supply DC 24V. Smoothing is performed with a capacitor through a diode through a DC 24V power source to generate a DC 32V power source. DC24V and DC32V are non-stable power supplies.

  DC24V is supplied to the power supply circuit 701 to generate constant voltage power supplies of stable power supplies DC18V, DC12V, and DC5V, and the main board 100, the payout control board 200, the lamp control board 400, the sound control board 500, and the display. Is supplied to the instrument control board 300 and the launch control board 600.

  The generated DC5V constant voltage power supply is connected to the capacitor of the backup circuit 702 through a diode to generate a DC5VBB backup power supply, and the DC5VBB is supplied to the main board 100 and the payout control board 200. The AC 24V is supplied to the card unit connection board 900, and is used as a communication power source for the payout control board 200 and the card unit b and a power source for the operation panel board a.

  The voltage level of the DC 24V power supply is detected by the voltage detection circuit 708 and output to the delay circuit 707. The delay circuit 707 has an internal time constant of 500 milliseconds, and the delay circuit 707 does not output an output signal unless the continuous output time of the voltage detection circuit 708 is larger than the time constant of the delay circuit 707. For this reason, voltage fluctuation and power supply stop for a time when the voltage level of the DC24V power supply is smaller than the time constant of the delay circuit 707 are ignored, and the power failure detection signal is not output from the power supply board 700 to the outside.

  When there is an input signal larger than the time constant in the delay circuit 707, the delay circuit 707 outputs a power failure detection signal to the main board 100, the payout control board 200, and the serial input terminals of the shift register 704. The 8-bit shift register 704 always receives a clock having a period of 20 milliseconds from the clock circuit 706.

  Here, the 8-bit data input terminal is fixed to zero. Therefore, when a power failure detection signal is input to the 8-bit shift register 704, a reset signal is output from the 8-bit shift register 704 after 8 clocks (about 160 milliseconds), the main board 100, the payout control board 200, and the launch control board 600. Are output to the display control board 300, the lamp control board 400, and the sound control board 500.

  The time of the time constant of the delay circuit 707, the power failure detection signal, and the reset signal are output in an active state from the time of the power source startup and after the power failure recovery, and the peripheral circuit power source startup. After the time constant of the delay circuit 707, the power failure detection signal becomes inactive, and the reset signal is output in the inactive state after 8 clocks of the 8-bit shift register 704. The RAM initialization signal is output to the main substrate 100 and the payout control substrate 200 in an active state by manually pressing the RAM initialization switch 705.

Next, the operation of the gaming machine main body 1 will be described.
In FIG. 1, when the player operates the handle 5, balls are driven one by one into a game area 17 (see FIG. 3) formed on the game board 2. When the ball wins the start opening 21, the start opening switch 121 detects the ball and outputs a detection signal to the main board 100 shown in FIG. Based on this detection signal, a display game in the variable display device 310 is started.

  FIG. 15 shows an example of the flow of the display game. When the display game is started, first, as shown in FIG. 15A, in the three display locations 311a to 311c partitioned by the variable display unit 311 of the variable display device 310, the Chinese numeral symbols are respectively displayed as identification information. Variable display to scroll in the direction. When a predetermined time elapses after the variable display is started, as shown in FIG. 15B, arbitrary identification information is stopped and displayed one by one in order from the left and right display locations 311a and 311b.

  When there is a possibility that a specific display mode is derived when two pieces of identification information are stopped at the left and right display locations 311a and 311b, as shown in FIG. 15B, the left and right display locations 311a and 311b A reach mode in which identification information of the same type is aligned is derived. Thereafter, the last identification information is stopped and displayed at the central display location 311c.

  As shown in FIG. 15 (c), when the identification information that is stopped and displayed last is the same type as the identification information that constitutes the reach mode, the display game execution results are all the same type of identification information. It becomes a specific display mode. When the specific display mode is determined, a special gaming state in which the special winning opening 24 is repeatedly opened and closed up to the maximum number of rounds of 15 is generated, and a game value is given to the player.

  On the other hand, as shown in FIG. 15D, when the identification information that is stopped and displayed last is different from the identification information that constitutes the reach mode, the display mode is changed. In this way, when the reach mode is derived in the display game but the specific display mode is not confirmed, any one of a plurality of types of items is automatically sent to the player by the item granting unit at the timing. Is granted. As shown in FIG. 15E, the items given to the player are sequentially displayed in the display column in the item display unit 312 of the variable display device 310, so that the player can easily list the acquired items. can do.

  In addition, the item type that the player acquires is obtained. By selecting any of a plurality of types of items at random by the item granting unit, The player can be given a thrill that is difficult to predict.

  Further, as shown in FIG. 15D, when the item is given to the player, the reach mode is derived when the reach mode is derived in the display game but the specific display mode is not determined. By giving an item to the player, in the state where the player is most discouraged, a future expectation will be caused by giving the item, and the player's feeling of discouragement can be alleviated to some extent. However, the item need not necessarily be 100% even at such timing, and may be set to be given with a predetermined probability.

  FIG. 16 shows another example of the flow of the display game. When the display game is started, first, as shown in FIG. 16A, first, as shown in FIG. 16 (a), the three display locations 311a to 311c partitioned by the variable display section 311 of the variable display device 310 each have Chinese numerals as identification information. The symbol is variably displayed so as to scroll vertically. When a predetermined time elapses after the variable display is started, as shown in FIG. 16B, arbitrary identification information is stopped and displayed one by one from the left and right display locations 311a and 311b.

  When the two pieces of identification information are stopped at the left and right display locations 311a and 311b, the reach mode is derived in the above-described example shown in FIG. 15, but in this display example, as shown in FIG. One identification information is stopped and displayed in different types, and the reach mode does not appear. Normally, at this time, it is not displayed until the last stop of the identification information at the central display location 311c, and the display mode is changed. .

  In this way, when the player acquires the item when a display mode disadvantageous to the player is derived during the display game, the item is automatically exercised by the item exercising means. Thus, display control is performed to re-variate any of the identification information that is once stopped and displayed that constitutes the disadvantageous display mode.

  Specifically, as shown in FIG. 16B, even when the reach mode can be derived in the display game, if the display mode that is disadvantageous to the player is quickly derived without the reach mode being derived, Thus, any of the items already acquired by the player is automatically exercised by the item exercising means.

  Thereby, on the display area of the variable display device 310, as shown in FIG. 16C, the actually exercised item moves from the item display unit 312 and temporarily stops at the right display location 311b to be changed again. The effect of moving to the identification information is displayed. Subsequently, as shown in FIG. 16D, various identification information is again displayed in the vertical direction at the right display portion 311b so that the identification information once stopped at the right display portion 311b is sequentially replaced with other identification information. Scroll to.

  By exercising the item in this way, the identification information once stopped and displayed is changed again, so that the progress of the display game is surprising, and the player can be given fresh interest. The exercised item disappears at the right display location 311b after being moved from the item display unit 312, and is deleted as it is.

  In addition, when an item is exercised, if the player acquires a plurality of items, the item is automatically exercised by the item exercising means in the order of acquisition date. That is, one is exercised each time from the item displayed on the rightmost side in each display column of the item display unit 312. In addition, when an item is exercised or the number of items displayed on the item display unit 312 is less than the upper limit value, the items are displayed on the display columns of the item display unit 312 in a left-justified manner.

  Furthermore, as shown in FIG. 16B, even when the reach mode can be derived in the display game, the display mode that is disadvantageous to the player is quickly derived without deriving the reach mode. In such a case, by exercising the item at this timing, it is possible to prevent a situation in which the player's sense of expectation is lost from the early stage of the display game. However, the item does not necessarily have to be 100% exercised at such timing, and it may be set to exercise with a predetermined probability.

  If the item exercised as described above satisfies a specific condition with respect to the re-changed identification information, the display mode shifting means is advantageous to the player from the disadvantageous display mode as a result of the re-change. Display control to shift to a different display mode is performed.

  In this way, when the specific condition is satisfied, the display mode shifts from an unfavorable display mode to an advantageous display mode, so that the expectation once given up by the player is revived, and the player's expectation is long and sufficiently aroused. can do. It can also provide substantial joy to collect items for the player.

  Specifically, when the item is exercised, data relating to an identifier corresponding to the item is stored in the RAM area. The identifier of the exercise item may be set so as to determine whether or not a predetermined specific condition is satisfied by comparing the identifier of the identification information re-varied in the display portion 311b on the right. The identification information re-varied at the right display location 311b means the identification information temporarily stopped and displayed at the right display location 311b in FIG. 16 (c). “5” corresponds to the identifier “4”. An identifier relating to such identification information is also stored in advance in the RAM area as stop symbol data.

  Specifically, for example, the identifier of the exercise item and the identifier of the re-variable identification information match each other with the same value, or the condition is relaxed within a range of ± 1-2 from each other. Etc. are considered. As another condition, in FIG. 16C, the value obtained by adding the identifier of the exercise item to the identifier of the identification information temporarily stopped and displayed at the right display portion 311b is stopped and displayed at the left display portion 311a. Various conditions can be set, for example, when it matches the identifier of the identification information.

  However, whether or not such a specific condition is satisfied depends on automatic control on the gaming machine side by the main board 100 or the like, so even if the contents of the specific condition are clearly indicated to the player The probability satisfying the specific condition can be appropriately set by the main substrate 100 or the like.

  When the specific condition as described above is satisfied, as a result of the re-variation, as shown in FIG. 16 (e), the display mode is shifted to the reach mode as an advantageous display mode for the player. Thereby, it is possible to restore the sense of expectation that the player has given up quickly during the display game. At this time, it is interesting to produce various reach actions to clarify that it has shifted to the reach mode as a result of re-variation.

  The probability as to whether or not to confirm the specific display mode after shifting to the reach mode is left to a random value by lottery of the main board 100. For example, the random mode can be changed in the middle so that the mode shifts to the reach mode. It is also conceivable that the probability control for changing the probability of confirming the specific display mode higher than that in the normal gaming state to be executed in association with the item exercise is also conceivable. Furthermore, the possibility of shifting to the specific display mode after re-variation may be set higher as the possibility that the specific condition is satisfied is smaller.

  Furthermore, when the specific display mode is determined as the execution result of the display game, a game that can be given with the occurrence of the special game state according to the number of items acquired by the player at that time It is also interesting to control the value to be different. Such control can be realized by game value changing means which is one of the functions of the main board 100.

  Here, as a measure for varying the game value, specifically, for example, the upper limit value of the number of rounds in the special game state is sequentially increased according to the number of items acquired, It is possible to increase the number of balls to be paid out based on winning a prize, increase the upper limit of the number of balls that can be awarded to the big winning opening 24 per round, or increase the opening time per round sequentially. It is done. It should be noted that after the special gaming state is completed, the player may reset so that all items acquired at that time are deleted.

17 and 18 show a second embodiment of the present invention.
In the present embodiment, the display game further includes scroll display means for scrolling the identification information from approximately the center of the rectangular display area in the variable display device 310 toward the four corners. In addition, the same code | symbol is attached | subjected to the site | part of the same kind as 1st Embodiment, and the overlapping description is abbreviate | omitted.

  The scroll display means first stops and confirms any identification information at the four corners of the rectangular display area in the variable display device 310, and finally identifies the identification information that stops at any one of the corners other than the four corners through a predetermined variable display. Execute display control to confirm the stop at the location. The reach mode deriving unit is set to derive the reach mode at any one of the four corners of the display area of the variable display device 310.

  FIG. 17 shows an example of a display game flow executed by the variable display device 310. When the display game is started, first, as shown in FIG. 17A, a plurality of types of identification information spread in an X shape from the approximate center of the rectangular display area in the variable display device 310 toward the four corners. Scroll X. As a result, not only the conventional vertical scrolling but also the horizontal and diagonal scrolling in one direction is not suitable. Can be realized.

  When a predetermined time has elapsed since the start of X scrolling, as shown in FIG. 17B, arbitrary identification information is stopped and displayed one by one for each display location corresponding to the four corners of the display area of the variable display device 310. Is done. At this time, when there is a possibility that a specific display mode is derived, a reach mode in which at least one set of the same type of identification information is gathered among the identification information stopped at the four corners of the display area is derived.

  The example shown in FIG. 17 (b) is a reach mode in which one set of identification information of the same type is arranged. Further, as shown in FIG. 18 (a), two sets of identification information of the same type are arranged. As shown in FIG. 18B, there may be a reach mode in which three identical types of identification information are arranged.

  In addition to the case where arbitrary identification information is stopped and displayed one by one in a predetermined order, display information corresponding to the four corners of the display area is displayed at four display information corresponding to the four corners of the display area. Is set so that two identification information (what constitutes the reach mode) is stopped and displayed at the same time at the display locations that can display the stop mode at the same time, or the reach mode such as upper right and lower left or upper left and lower right. Also good.

  When each piece of identification information stops at the four corners of the display area, the illustration is omitted in FIG. 17. However, if the pieces of identification information are all different from each other and the reach mode is not derived, the above-described first embodiment is performed at this timing. Items are automatically exercised as in.

  As shown in FIG. 17B, when a reach mode in which at least one set of the same type of identification information is arranged is derived, the identification information to be stopped last is subjected to predetermined variable display, and the four corners of the display area are displayed. Stop at any display location other than. That is, as shown in FIG. 17C, one piece of identification information appearing at the approximate center of the display area does not change to other pieces of identification information in sequence and stops after moving to any place as it is. To do.

  As a result, as shown in FIG. 17 (d), the identification information that stops last is the same type as the identification information that constitutes the reach mode, and is displayed at the display location on the reach line L shown in the figure. When stopped, the specific display mode is determined. As a result, a special gaming state in which the special winning opening 24 is repeatedly opened and closed up to a maximum of 15 rounds is generated, and a gaming value is given to the player.

  On the other hand, although not shown in FIG. 17, when the identification information to be stopped last is the same type as the identification information constituting the reach mode, but stopped at a different display location instead of on the reach line L Or, if the identification information last stopped on the reach line L is of a different type from the identification information that constitutes the reach mode, the display mode is changed. As described above, if the specific display mode is not determined through the reach mode, the item is automatically given at this timing as in the case of the first embodiment described above.

  As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the present invention can be modified or added without departing from the scope of the present invention. Included in the invention. In the above-described embodiment, the case where the gaming machine according to the present invention is applied to a pachinko machine has been described. However, the gaming machine is not limited to a pachinko machine, and is a program-controlled smart ball game machine, an arrangement ball game machine, or the like. The present invention can be similarly applied to other gaming machines. The variable display device 310 can be applied to a slot machine.

  In the above-described embodiment, an example has been described in which functions such as an item granting unit, an item exercising unit, a display mode transition unit, and a reach mode deriving unit are realized by the main board 100 and the display control board 300. You may comprise so that each of these functions may be implement | achieved by the game effect control board provided on the same board | substrate with the function of the display control board 300, the lamp control board 400, and the audio | voice control board 500.

  Here, the game effect control means functions as display control means for performing display control on the variable display device 310, decoration control means for controlling blinking of various lamps, and sound control means for controlling sound output from the speaker 510. To fulfill. As described above, the specific configuration for realizing the various means described above is not limited to the various control boards specifically shown in FIGS. 5 and 6.

  In the above-described embodiment, the timing when the item is given to the player has been described by way of example when the reach mode is derived in the display game, but the specific display mode is not determined. Is only an example, and other items such as, for example, rarely items are given even when the display mode appears without going through the reach mode, or the special game state is occurring regardless of the display game It can be given as a round effect, or when the power is turned on.

  Further, in the above-described embodiment, as the timing of exercising an item, even when the reach mode can be derived in the display game, the case where the display mode that is disadvantageous to the player is quickly derived without the reach mode being derived is described. However, the timing related to the item exercise is merely an example. In addition, for example, when a discontinuous display mode is finally derived after all identification information is stopped, or a display mode that is advantageous in so-called development reach has been developed. It may be set at a timing related to various unfavorable display modes during the display game when there is no such event.

  The present invention is particularly applicable to gaming machines represented by pachinko gaming machines, coin gaming machines, slot machines, and the like.
