The shape of the curved surface 711B of the bottom wall 712 is not limited to the curved shape as long as the shape is the same as the shape of the lower right portion of the game area 31 of the gaming board 30 (curved shape in this example). It may be formed. By forming a shape equivalent to or corresponding to the shape of the lower right portion of the game area 31, the space on the back surface of the game area 31 in the game board 30 can be used effectively.

Further, in this example, in a state where the solenoid 860 is disposed on its side, the jig insertion hole 750 is provided on the right side from which the plunger 860A protrudes, so that via the jig insertion hole 750, It is possible to easily check the operation of the plunger 860A and the crank 870 of the solenoid 860 in the closed state and the other components interlocked with the plunger 860A.
In this example, the jig insertion hole 750 is provided on the right side wall 744 side of the upper case 730, but may be provided on the bottom wall 712 side of the lower case 710 connected to the right side wall 744. More preferably, if it is provided at the axial center of the plunger 860A protruding in a shaft shape, or at a position parallel to the vertical axis with respect to the axial center, the plunger 860A is moved to the back side by the tip of the jig when the jig is inserted ( It is possible to push in without applying unnecessary stress to the left side). In this example, a jig insertion hole 750 is provided at a position corresponding to the head of the connecting pin 862 that connects the tip of the plunger 860A and the crank 870.

  Next, with reference to FIG. 8, the flow of the game of the pachinko machine 1 will be outlined, and a special game in which the above-described second grand prize device 80 operates will be described. As shown in FIG. 8, the pachinko machine 1 includes a main control device 100, a sub control device 200, a payout control device 400, and a launch control device 500 as main components, and is generated based on execution of main processing by the main control device 100. Other control devices operate according to the various commands. Each of the above control devices includes a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores programs necessary for game processing and data necessary for game processing, and a computer in which the CPU is stored in ROM. The microcomputer includes a RAM (Random Access Memory) that is a temporary storage area for performing processing according to a program, and is disposed on the back side of the game board 30 via an attachment mechanism (not shown). Hereinafter, main processes performed by the main controller 100 will be described.

  The main controller 100 is triggered by input from the first start port detection sensor SS1 and the second start port detection sensor SS2 that are output in response to winning of the first start winning component 60 or the second start winning component 61, respectively. Then, a lottery process for determining whether or not the special game can be executed, a special figure type (big hit type) lottery process, and a variable time determination process executed when the result of the lottery is a win.

  In this lottery process, random numbers (0 to 65536) that are acquired by using the input from the first start port detection sensor SS1 or the second start port detection sensor SS2 as a trigger (0 to 65536) and the plurality of random numbers are “ With reference to a predetermined success / failure lottery table in which “win” or “out” is defined, a success / failure lottery result (“win” or “out”) corresponding to the acquired random number is selected. Here, the result of the success / failure lottery The probability of winning a “win” is set to, for example, 1/399, but if it is in a so-called “probability change game (probability change game)”, another winning / failing lottery referred to in the probability change game By referring to the table, the probability that the result of winning / failing lottery is “winning” is improved to, for example, 1/40, and the maximum number of stored random numbers (holding number) is the first start port detection sensor. SS1 and second start port detection sensor Each of the inputs from the SS 2 is up to 4 (maximum of 8), and the stored random numbers are sequentially read out based on satisfying the start condition, and the lottery is executed. Thus, the starting condition is that the special symbol is not changing and the special game is not being executed, and when the condition is satisfied, the above-mentioned lottery process is executed.

When the result of the above-mentioned lottery determination is “Win”, a special figure type lottery process by the main control device 100 is executed. The special figure type lottery process is acquired by using an input from the first start port detection sensor SS1 or the second start port detection sensor SS2 (for special figure type lottery) and the plurality of random numbers. The special symbol type corresponding to the acquired random number is selected with reference to a predetermined special symbol type lottery table in which special symbol types from “special symbol A” to “special symbol D” are defined. To do.
Here, for example, when “special symbol A” is selected, the number displayed on the first special symbol display device or the second special symbol display device outside the figure is “1 · 1”. A special game (a jackpot game), which will be described later, executed after the special symbol “A” is stopped and displayed, is defined as a 4R (round) special game by the operation of the first big winning device 70. For example, when “special symbol B” is selected, the number displayed on the first special symbol display device or the second special symbol display device outside the figure is “5.5”, and the “special symbol B” is further displayed. A special game (a jackpot game) to be described later that is executed after the symbol “B” is stopped and displayed is defined as an 8R (round) special game based on the operation of the first big winning device 70. For example, when “special symbol C” is selected, the number displayed on the first special symbol display device or the second special symbol display device outside the figure is “3.3”, and the “special symbol C” is further displayed. A special game (a jackpot game), which will be described later, which is executed after the symbol “C” is stopped and displayed, is defined as a special game of 10R (round) by the operation of the second big winning device 80. For example, when “special symbol D” is selected, the number displayed on the first special symbol display device or the second special symbol display device outside the figure is “7.7”, and the “special symbol D” is further displayed. A special game (a jackpot game), which will be described later, executed after the symbol “D” is stopped and displayed, is defined as a special game of 16R (round) by the operation of the second big winning device 80.

  As described above, the special figure type lottery process is a process for determining a special symbol mode (a sequence of numbers in this example), and a process for determining a special game mode to be executed after the special symbol is stopped. The mode of the special game is determined according to the type of special symbol selected by the process. Although the details are omitted, the ratio of the plurality of special symbols is selected based on whether the special figure type lottery random number is input from the first start port detection sensor SS1 or the second start port detection sensor SS2. It is set differently depending on whether it is acquired as an opportunity, for example, the special figure type lottery process that is executed based on the random number acquired in response to the input of the second start port detection sensor SS2 The ratio of selecting “special symbol C” or “special symbol D” is set higher than the special symbol type lottery process executed based on the random number acquired in response to the input of the first start port detection sensor SS1. Has been. Note that the types of special symbols are only examples, and a plurality of special symbol types may be provided, and more various modes such as 1R, 2R, and 12R may be set for the modes of special games.

Next, the variation time determination process will be described. The variation time determination process is performed with respect to random numbers (0 to 99) (for variation time determination) acquired with the input from the first start port detection sensor SS1 or the second start port detection sensor SS2 and the plurality of random numbers. The variation time corresponding to the acquired random number is selected by referring to a predetermined variation time determination table in which a plurality of variation times of the special symbol are defined. In this example, the special symbol fluctuation time is defined as “2 seconds”, “4 seconds”, “8 seconds”, “11 seconds”, “30 seconds”, “45 seconds”, “60 seconds”, etc. Any variation time corresponding to the random number is selected. The variable time determination table is composed of a plurality of tables that are referred to according to the above-described lottery result and the current gaming state (for example, “normal state” or “probability changed state”). For example, when the result of the lottery determination is “winning”, the variation time becomes longer by referring to a table in which the ratio of the variation time determined to be “45 seconds” and “60 seconds” is set high. Tend to be. Further, when the gaming state is “probable change game”, the variation time is shortened by referring to a table set with a high ratio of the variation time determined as “2 seconds” and “4 seconds”. It becomes a trend. The variation time determined by the variation time determination process is used as the variation time of the effect symbol S that is variably displayed on the effect display device 300, and is displayed on the first special symbol display device or the second special symbol display device. The variation time of the special symbol that is variably displayed and the variation symbol S that is variably displayed on the effect display device 300 are substantially synchronized.

The main control device 100 outputs a control signal to the first special symbol display device or the second special symbol display device based on the results selected by the above-mentioned lottery processing, special symbol type lottery processing, and variation time determination processing. A special symbol variation is started, and an effect symbol variation command including the result information is generated and transmitted to the sub-control device 200. Then, on the side of the sub-control device 200, a notice pattern, reach pattern, or other effect pattern is determined according to various information included in the effect symbol variation command, and a change start command including the determined pattern information is issued. It transmits to the production display device 300 side. On the side of the effect display device 300, on the basis of the reception of the change start command, the change display of the effect symbol S is started, and image data and moving image data corresponding to the notice pattern and the reach pattern are read from storage means such as a ROM outside the figure. The read data is output on the display screen. And the effect design which started the variable display is stopped and displayed in the aspect which shows the result of the above-mentioned lottery lottery with progress of the predetermined variation time, and notifies the result of the lottery lottery to the player. Here, for example, when the result of the lottery result is “winning”, the stop mode is a mode in which the same number or character stops linearly on a predetermined hit line, and is “off”. Aspects are aspects other than those described above.

  Next, a description will be given of the special game process that is executed after the special symbol lottery result is “winning” and the special symbol and the effect symbol are stopped in a manner indicating that the special symbol and the effect symbol are stopped. In the special game process, the first big prize device 70 or the second big prize device 80 is operated under the control of the main control device 100, and the game balls launched in the game area 31 are won in the respective big prize ports 70A or 80A. The main control device 100 operates the first big prize device 70 or the second big prize device 80 according to the type of the special symbol after the special symbol and the production symbol are stopped, and is different from each other. The special game of the aspect is started.

When the special symbol type is “special symbol A” or “special symbol B”, the main control device 100 outputs a drive signal to the solenoid SOL1 of the first big prize winning device 70 to output 4R or 8R. Perform special games. Here, in the “one round”, a predetermined upper limit number of game balls are detected by the first big prize opening detection sensor TS1 after the big prize opening opening / closing body 70B is opened by the excitation of the solenoid SOL1. Or until the predetermined time elapses after the special prize opening opening / closing body 70B is in the open state, until the earlier condition is satisfied, and in the case of 4R, the opening / closing operation is 4 If it is 8R, the opening / closing operation is repeated 8 times. In addition, the closing time of the big prize opening / closing body 70B between rounds is set to 2.5 seconds, for example.
That is, during a special game in which the first grand prize winning device 70 opens, the player launches a game ball so that the game ball is taken into the first big prize winning device 70 (launching toward the game area L1 side). ), It is possible to receive a lot of prize balls at a time.

  On the other hand, when the type of the special symbol is “special symbol C” or “special symbol D”, the main controller 100 outputs a drive signal to the solenoid 860 of the second big prize device 80 and outputs 10R or A 16R special game is executed. Here, in the “one round”, the upper limit number of game balls set in advance after the open / close body 800 is moved to the rear of the game board 30 by the excitation of the solenoid 860 and the special winning opening 80A is opened. The condition that is detected by the second big prize opening detection sensor TS2 or until a predetermined time elapses after the opening / closing body 800 moves rearward and the big prize opening 80A is opened. The opening / closing operation is repeated 10 times if 10R, and the opening / closing operation is repeated 16 times if 16R. Similarly to the above, the closing time of the opening / closing body 800 between rounds is set to 2.5 seconds, for example. In other words, during a special game in which the second grand prize device 80 is opened, the player launches a game ball so that the game ball is taken into the second grand prize device 80 (launching to the game area R1 side). ), It is possible to receive a lot of prize balls at a time.

  In addition to the main processes described above, the main controller 100 includes the first start port detection sensor SS1, the second start port detection sensor SS2, the general winning port detection sensor IS, the first big winning port detection sensor TS1, and the second big winning award. A prize ball payout command is generated in response to an input from any of the mouth detection sensors TS2 and output to the payout control device 400. The prize ball payout command includes prize ball number information associated with each sensor in advance, and the payout control apparatus 400 drives and controls the prize ball payout apparatus 450 based on the prize ball number information, and the player Awarding a prize ball as a consideration for the game. Here, for example, the number of prize balls for the inputs from the first start opening detection sensor SS1, the second start opening detection sensor SS2, and the general winning opening detection sensor IS is set to three, and the first big winning opening detection sensor The number of prize balls for the inputs from TS1 and the second big prize opening detection sensor TS2 is set to fifteen. Thereby, in the special game, the player can obtain a large amount of prize balls at a time.
