  As shown in FIG. 6, the operation of the pachinko machine 2 is basically controlled by the main control board 25 and the sub control board 26. The main control board 25 and the sub control board 26 are each provided with a connection terminal, and the main control board 25 and the sub control board 26 are electrically connected by connecting the connection terminals with a connection cable or the like.

  The main control board 25 includes a main CPU (central processing unit) 25a, a main ROM (read only memory) 25b, a main RAM (random access memory) 25c, a big hit lottery unit 25d, and a small hit lottery unit 25e. The main CPU 25a reads a game control program stored in the main ROM 25b in response to an input signal input from the winning ball detection sensor 16, generates a command for controlling the gaming state of the pachinko machine, and also controls the sub-control board 26. The command information is transmitted to and executed in a predetermined gaming state. In the main ROM 25b, a game control program, a random number generation processing program, a random number table, and the like are stored in predetermined areas, and these are read out by the main CPU 25a and used appropriately so as to be processed. The main RAM 25c is a working area and is used for temporary storage or rewriting of data used in the game.

  When the signal from the winning ball detection sensor 16 is input, the main CPU 25a drives the ball payout device 30 based on the game control program stored in the main ROM 25b to supply a predetermined number of winning balls on the supply tray 6 Pay out. Note that the number of prize balls may be set as appropriate according to the type of each prize-winning slot 10 or 11 containing game balls. The ball launcher 17 is connected to the main CPU 25a, and the drive is controlled by the main CPU 25a.

  The sub control board 26 includes a sub CPU 26a, a sub ROM 26b, and a sub RAM 26c. The sub CPU 26a appropriately reads out the control program for the sub control device stored in the sub ROM 26b, and according to the control signal input as command information from the main control board 25, the sub CPU 26a performs the control of the symbol variable display device 9 Drive control is performed. The sub RAM 26c is a working area, and is used for temporary storage or rewriting of data used in the control of the symbol variable display device 9.

  When the pachinko ball 7 entering the start winning opening 10 is detected by the winning ball detection sensor 16, a start signal is input to the main CPU 25a. The main CPU 25a operates the big hit lottery section 25d in response to the start signal.

  The jackpot lottery unit 25d includes a random number generator, a random number sampling circuit, and a jackpot determination table. Each time a winning of the pachinko ball 7 is detected by the winning ball detection sensor 16 of the start winning opening 10, a random number value is lottery. To do. The lottery random value is checked against the jackpot table, whether or not to shift to the jackpot mode is determined as a result of the lottery determination, and information (for example, command) related to the determination is generated.

  In the jackpot determination table, random numbers are grouped into three groups according to their sizes. The three random number groups are assigned “normal jackpot” that shifts to the loss, normal jackpot mode, and “probable jackpot” that shifts to the probability fluctuation jackpot (hereinafter, probability variation jackpot) mode that has a different probability of jackpot than normal. The winning determination is performed to determine whether to be lost or jackpot depending on which group the sampled random number value belongs to. When the lottery is completed, a lottery result signal is fed back to the main CPU 25a. The main CPU 25a sends a lottery result signal to the sub CPU 26a.

  When the “normal jackpot” or “probability big hit” is drawn by the big hit lottery section 25d, the main CPU 25a rotates the attacker 13 to the open position, and the attacker 13 is released for 30 seconds or is placed in the big prize opening 18. Whether or not 10 pachinko balls 7 are won (10 pachinko balls 7 are detected by the big winning ball detection sensor 19) is one round, and a predetermined round (for example, 15 rounds) is continuously executed. Further, when “probable big hit” is drawn, a probable big hit determination table different from the normal time is used at the time of lottery until the next big win is drawn.

  When the pachinko ball 7 that has entered the passing winning opening 12 is detected by the winning ball detection sensor 16, a small winning lottery signal is input to the main CPU 25a. The main CPU 25a operates the small hitting lottery section 25e in response to the small hitting lottery signal.

  The small winning lottery unit 25e includes a random number generator, a random number sampling circuit, and a small winning determination table, and each time a winning of the pachinko ball 7 is detected by the winning ball detection sensor 16 of the passing winning opening 12, one random number value is obtained. Lottery. The lottery random value is checked against the small hit table, whether or not to shift to the small hit mode is determined as a result of the lottery determination, and information (for example, command) related to the determination is generated. Note that in normal times, one small lottery is performed in a predetermined time (for example, 30 seconds).

  In the small hit determination table, random numbers are grouped into two groups according to their sizes. The two random value groups are assigned “small hits” for shifting to the loss and small hit mode, respectively. Depending on which group the sampled random number values belong to, either the lost or the small hits are assigned. A winning decision is made to determine whether to win. When the lottery is completed, a lottery result signal is fed back to the main CPU 25a. The main CPU 25a sends a lottery result signal to the sub CPU 26a.

  The main CPU 25a controls the driving of the motor 23 when the “small hit” is drawn by the small hit lottery section 25e, and rotates the introduction accessory 20 to the open position, so that the start winning opening 10 is kept for a predetermined time (for example, 0.5 seconds) When released, the introduction accessory 20 is rotated to the closed position. Also, when the above-mentioned “probable big hit” is drawn, after the big win is finished, until the next big hit is drawn and this big hit is started (the attacker 13 is rotated to the open position). One small lottery is performed for a predetermined time (for example, 2 seconds), and when the “small winning” is selected, the start winning opening 10 is opened for a predetermined time (for example, 3 seconds). That is, when the “probability jackpot” is drawn, after the jackpot ends, the state where it is easy to win the start winning opening 10 continues until the next jackpot is drawn and this jackpot is started. Become. Thereby, the player can play a game without reducing the total number of pachinko balls 7 acquired until the next jackpot.

  The sub ROM 26b of the sub control board 26 stores graphic data of each special symbol, a random symbol sampling circuit for stop symbols, and a stop symbol table. When the lottery result signal is input, the sub CPU 26a samples the random number value based on the stop symbol random number sampling circuit stored in the sub ROM 26b, and compares the sampled random number value with the stop symbol table. There are three types of stop symbol tables for lost, big hit, and probable big hit, and the random number sampled is collated with the stop symbol table corresponding to the lottery result in the big hit lottery section 25d. Each stop symbol table is assigned a special symbol combination for stopping on the winning active line to the grouped random value, and the group to which the sampled random value belongs The combination of special symbols to be stopped on the winning line is determined. The sub CPU 26a controls the change display and stop display of the special symbol on the symbol variable display device 9 based on the determined combination of the special symbols. In the stop symbol table, for example, when two special symbols are stopped on the winning line, a special symbol is aligned, that is, a special symbol change mode when reaching a reach state, a symbol variable display It also includes data on whether or not to make a special symbol change mode different from the normal time, such as a special symbol change mode in a reach notice and a special symbol stop mode in a jackpot notice.

  The operation of the pachinko machine 2 configured as described above will be described. When the pachinko ball 7 that has entered the passing winning opening 12 is detected by the winning ball detection sensor 16, a small winning lottery signal is input to the main CPU 25a. The main CPU 25a operates the small hitting lottery section 25e in response to the small hitting lottery signal. The small hitting lottery unit 25e draws one random value. When the “small hit” is drawn by the small hit lottery section 25e, the main CPU 25a controls the driving of the motor 23, rotates the introduction accessory 20 to the open position, and the start winning opening 10 is 0.5 seconds ( When it is released for 3 seconds (at the time of probability change) or at normal time, the introducer 20 is rotated to the closed position. When the introduction combination 20 is rotated to the open position, the start winning opening 10 is opened, and the pachinko ball 7 that is in contact with the back surface of the open / close door 21 is guided to the start winning opening 10. On the other hand, when the introduction accessory 20 is rotated to the closed position, the pachinko ball 7 enters from the inlet 22b having an opening width (approximately 15 mm) that is 30% of the opening width (approximately 50 mm) of the start winning opening 10; The start winning opening 10 is won through the introduction passage 22a. That is, when the introductory accessory 20 is rotated to the open position, the pachinko ball 7 is more likely to win the start winning opening 10 than when it is rotated to the closed position.

  As described above, the introductory accessory 20 can make it easier to win the start winning opening 10 than usual, and the tulip type accessory including the guiding portion and the two blades can be used as the starting winning opening 10. The size can be reduced in the vertical direction as compared with the case of using as an accessory.

  Further, the ball receiving portion 22 is brought close to the rotating shaft 21b side, which is a shaft mounting portion of the opening / closing door 21, so that the bottom surface of the opening / closing door 21 is substantially coincident with the bottom surface of the opening / closing door 21. Therefore, as compared with the case where the ball receiving portion 22 is formed close to the upper end portion side of the open / close door 21, the time until the ball receiving portion 22 comes into contact with the glass disposed on the front surface side of the introduction accessory 20. Since a moving angle becomes large, it can implement also in the pachinko machine with a small clearance gap between the introducing | transducing accessory 20 and glass.

  In the present embodiment, the winning winning opening 10 is used as an accessory. However, the present embodiment is not limited to this. The normal winning opening 11 may be used as an accessory 13.
