A stage 50 on which the game ball can roll is provided.

  Further, a front decorative body 80 that constitutes a part of the center unit 40 and forms the outer edge of the center unit 40 is provided. Thus, the front decorative body 80 is provided with the swing passage member 43 and the ball passage member 49 described above, and a decorative lens cover corresponding to the normal symbol display 44, the universal start memory LED 48, and the status display LED 45. Is provided.

  Further, a discharge stage 80 a constituting a part of the stage 50 is formed at the lower edge portion of the front decorative body 80. The discharge stage 80a makes it possible to discharge the game ball that rolls on the stage 50 while tilting at a predetermined angle toward the front of the pachinko machine 1 to the game area 12.

  The front decorative body 80 has a predetermined thickness forward from the board surface of the game board 4 so as to regulate the flow of game balls in the game area 12, and the game balls flowing down the game area 12 are decorated in front. By contacting the outer wall of the body 80, the game ball is guided to one of the left and right sides of the front decorative body 80, and the game ball is allowed to enter so as not to hinder the visual recognition of the image display device 42 and the rotational driving of the rotating accessory 61. Blocking.

  Thus, a part of the outer wall of the front decorative body 80 is formed with the inlet 40a of the ball passage path, the inlet of the spherical passage member 49, and the inlet of the swing passage member 43 provided at the upper left. .

  A gate 74 is provided on the left side of the center unit 40. The gate 74 is provided with a gate switch 74a (see FIG. 11) that detects a game ball that has passed through the gate 74. It should be noted that the normal symbol change display on the normal symbol display 44 described above is started based on the fact that the game ball has passed through the gate 74 and the game ball is detected by the gate switch 74a. That is, the normal symbol display on the normal symbol display 44 is permitted in accordance with the detection of the game ball by the gate switch 74a.

  A variable winning device 70 is disposed below the center of the center unit 40. The variable winning device 70 receives a first starting port 72 from which a game ball can be won from above, a second starting port 73 provided below the first starting port 72, and a game ball won in the first starting port 72. A start port switch 70a (only the reference numeral is shown in FIG. 5) for detecting and a start port switch 70b (only the reference numeral shown in FIG. 5) for detecting a game ball won in the second start port 73 are provided. Further, on both sides of the second starting port 73, a pair of movable pieces 71 are provided that can be rotated around a lower portion by a solenoid 71a. The second starting port 73 is normally closed by a first starting port 72 positioned above and a movable piece 71 positioned on both sides of the second starting port 73 so that a game ball cannot be won. The solenoid 71a is moved and the movable piece 71 is rotated to control the open state in which the game ball can be won from the left and right directions. In addition, a predetermined number (for example, three) of game balls are paid out based on the detection of the game ball at the first start port 72 and the detection by the start port switch 70a, and the second start port 73 has a game. A predetermined number (for example, four) of game balls are paid out based on the winning of the ball and detection by the start port switch 70b.

  The discharge stage 80a formed at the lower edge portion of the front decorative body 80 is located directly above the variable prize-winning device 70, so that the game balls discharged from the discharge stage 80a are the first start port. 72 and the second starting port 73 are easy to win. However, the ball discharge portion of the discharge stage 80a is formed wider than the diameter of the game ball. For this reason, the rate at which the game ball wins the first start port 72 or the second start port 73 varies depending on the discharge portion of the game ball at the discharge stage 80a. That is, the configuration in which the game balls discharged from the discharge stage 80a are likely to win the first start port 72 and the second start port 73 is that the game balls roll on the stage 50 (on the circular guide portion 54 described later). It means that it is easier to win compared to the case where the first start port 72 or the second start port 73 is won without rolling), and the game ball discharged from the discharge stage 80a is not necessarily the first start port 72. Or, it does not win the second starting port 73.

  Further, when the game ball enters the swing passage member 43 provided at the left and right lower ends of the front decorative body 80, the game ball can be guided toward the center of the game area 12 in which the variable winning device 70 is disposed. That is, even when the game ball is not guided to the stage 50 by the swing passage member 43 and the ball passage member 49 provided at the upper left part of the front face of the front decorative body 80, the front decorative body 80 is positioned at the left and right lower ends. Since the game ball enters the swinging passage member 43 that is guided to the center of the game area 12 provided with the variable winning device 70, the game ball is not guided to the center of the game area 12. The winning rate for the first start port 72 and the second start port 73 is increased. The swing passage member 43 swings left and right around a rotation axis that protrudes vertically on the front surface of the game board 4 when a game ball passes. Thus, since the swing passage member 43 swings left and right when the game ball passes, the passage of the game ball can be confirmed, the game can be changed, and the player is not bored. be able to.

  Thus, in order to guide the game ball on the stage 50 when the game ball enters the swing passage member 43, or to guide the game ball toward the center of the game area where the variable winning device 70 is arranged. Thus, when a game ball enters the swing passage member 43, it is possible to enhance the expectation for winning in the first start port 72 and the second start port 73.

  Below the variable winning device 70, a large winning opening / closing device 75 is disposed. The special prize opening / closing device 75 has a special prize opening in a predetermined area. Also, the entrance of the prize winning opening is formed in a horizontally-long rectangular shape, and the prize opening opening / closing device 75 is provided in front of the entrance of the prize winning opening, and can be rotated by a solenoid 76a with the lower part as a fulcrum. And a count switch 75a (only the reference numeral is shown in FIG. 5) for detecting a game ball won in the big winning opening. It should be noted that the prize winning opening / closing device 75 is normally controlled so that the front door 76 stands up and closes the entrance of the prize winning opening so that the game ball cannot be won, moves the solenoid 76a, and moves the front door 76. The pachinko machine 1 is rotated in the forward direction with the lower part of the pachinko as a fulcrum, and the game ball is controlled to an open state in which a prize can be won. Also, a predetermined number (for example, 14) of game balls are paid out based on the winning of the game balls at the special winning opening and detection by the count switch 75a.

  In addition, at the lowermost part of the game area 12 below the big prize opening / closing device 75, the game area 12 flows down and the game balls that have not won any prize opening or prize device are discharged from the game area 12. An out port 77 is provided. The game area 12 is also provided with a plurality of general winning holes 13 through which game balls can be won from above, and a predetermined number of game balls are paid out based on the winning of the game balls into the general winning holes 13. . Note that the game ball that won the general prize opening 13 was detected by the general prize opening switch 13a (only the reference numeral is shown in FIG. 5), and the game ball won the general prize opening 13 and was detected by the general prize opening switch 13a. Based on this, a predetermined number (for example, 10) of game balls are paid out.

  Although not shown, each device such as the center unit 40 provided in the game area 12 of the game board 4 is provided with a plurality of lamps and LEDs (for example, the upper lamp 88). Then, the effect of the effect is enhanced by controlling the lighting and extinction of the lamp and the LED in accordance with the effect mode of the effect executed by the image display device 42. Hereinafter, these lamps and LEDs may be referred to as game board lamps. In addition, although not shown, a plurality of obstacle nails projecting from the front surface of the game board 4 (the side where the game area 12 is formed) change the flow direction of the game ball and makes the behavior of the game ball interesting.

  FIG. 5 is a block diagram illustrating an example of a circuit configuration in the main board group and the peripheral board group. Various boards constituting the main board group and the peripheral board group are attached to the back side of the game board 4.

  The main board group includes a main board 101 and a payout board 105. The main board 101 includes a CPU 102 as a central processing unit, a ROM 103 as a read-only memory, and a RAM 104 as a readable / writable memory. The CPU 102 controls various games performed in the pachinko machine 1 by executing a game control program stored in the ROM 103, and creates a signal to be transmitted to the peripheral board group and the payout board 105. Further, the RAM 104 temporarily stores various data generated in various processes executed on the main board 101 and information such as input signals.

  The main board 101 receives detection signals from the gate switch 74a, the start port switches 70a and 70b, the count switch 75a, the general winning port switch 13a, and the like. And CPU102 performs the process according to these input detection signals. That is, based on the input detection signal, the solenoids 71a and 76a, the special symbol display 41, the normal symbol display 44, the special diagram start memory lamp 47, the general diagram start memory LED 48, the status display LED 45, the big hit type display LED 46, etc. A drive signal is output to. Further, a signal instructing the payout board 105 to pay out the game ball according to the winning is output.

  The payout board 105 includes a payout CPU 106 as a central processing unit, a payout ROM 107 as a read-only memory, and a payout RAM 108 as a readable / writable memory. When a game ball is detected by the above-described start port switches 70a and 70b, count switch 75a, general winning port switch 13a, etc., detection signals are input from the switches to the main board 101, and detection signals are input. Based on this, the CPU 102 mounted on the main board 101 transmits a signal instructing the payout board 105 to pay out the game ball. The payout board 105 processes the signal received from the main board 101 and outputs a drive signal to the payout device 109 (payout motor). Based on the input of the drive signal, the payout device 109 pays out the game ball.

  Also, a launching device 135 having a launching motor that launches a game ball toward the game area 12 is connected to the payout board 105. Then, based on the operation of the operation handle 18, the launch motor 135 drives the launch motor to launch a game ball. Although not shown, the launching device 135 has a built-in touch sensor that detects that the player is touching the operation handle 18, detects that the player is touching the touch handle, and further controls the operation handle 18. The firing motor 135 can be driven by the launching device 135 based on the operation of. In addition, a lower pan full switch for detecting that the lower pan is full is provided, and the operation of the operation handle 18 is controlled so that it cannot be accepted when a detection signal is input from the lower pan full switch. The firing motor 135 may not be able to drive the firing motor. That is, the game balls paid out from the payout device 109 are stored in the upper plate 28, but when the game balls that cannot be stored in the upper plate 28 are discharged, the lower plate communicated with the upper plate 28. 17 is stored. In this state, when a game ball is further paid out from the payout device 109, a detection signal is output by a lower plate full tank switch that detects that the lower plate 17 is full, and this detection signal is input. Sometimes, the operation of the operation handle 18 may be controlled to be unacceptable. In this case, it may be configured such that the operation of the operation handle 18 can be received based on the fact that the detection signal from the lower pan full switch is not input.

  The peripheral board group includes a sub-integrated board 111, a lamp relay board 119, an accessory control board 115, and a display control board 120. The sub-integrated board 111 includes an integrated CPU 112, an integrated ROM 113, and an integrated RAM 114. The sub-integrated board 111 also includes a sound source IC 128 that performs control related to sound output, and a sound ROM 127 as a read-only memory related to sound output. The integrated CPU 112 executes a process based on a signal received from the main board 101 by executing an effect control program stored in the integrated ROM 113. The integrated RAM 114 temporarily stores information such as various data generated in various processes executed by the sub-integrated board 111, input / output signals, signals received from the main board 101, and the like. The integrated CPU 112 reads a signal received from the main board 101 stored in the RAM 114, transmits a signal to the display control board 120 and the lamp relay board 119 based on the read signal, and a signal read by the sound source IC 128. Based on this, a sound output mode is read from the sound ROM 127, and a drive signal corresponding to the read sound output mode is output to the upper speaker 29 and the lower speaker 14, or a drive signal is output to the frame lamp 27.

  The lamp relay board 119 transmits the signal received from the main board 101 to the game board lamp and the accessory control board 115. Note that the lamp relay board 119 only transmits a signal transmitted from the main board 101 to the game board lamp and the accessory control board 115, and the control of the game board lamp and the accessory control board 115 is substantially controlled by the sub-board. Performed by the integrated substrate 111. Hereinafter, the lamp relay board 119 may be omitted for explanation.

  The accessory control board 115 includes an accessory CPU 116 as a central processing unit, an accessory ROM 117 as a read-only memory, and an accessory RAM 118 as a readable / writable memory. The display control board 120 includes a display CPU 121 as a central processing unit, a display ROM 122 as a read-only memory, and a display RAM 123 as a readable / writable memory.

  The accessory CPU 116 mounted on the accessory control board 115 outputs a drive signal to the motor 63 and the LED 61a based on the signal received from the sub-integrated board 111 via the lamp relay board 119. By rotating the motor 63, the rotation of the rotating object 61 is controlled by outputting a drive signal to the motor 63, and afterimages of a predetermined form are displayed by outputting the drive signal to the LED 61a. Further, the display CPU 121 mounted on the display control board 120 controls the image display device 42 based on a signal from the sub-integrated board 111.

  Here, a game realized by the game board 4 provided with the various components and devices described above will be described. When the player operates the operation handle 18, a game ball is launched by the launching device 135 provided on the back side of the pachinko machine 1. The game ball launched from the launching device 135 is discharged to the upper part of the game area 12 through the launch rail 15 and the guide rail 11, and flows down toward the out port 77 while colliding with the obstacle nail or the like. Then, when the game ball flowing down the game area 12 passes through the gate 74 and is detected by the gate switch 74a, the normal symbol display 44 changes the normal symbol (the LED is lit in green and red alternately). Is started.

  When a game ball is detected by the gate switch 74a, the normal random number per symbol is extracted from a counter that updates the normal random number per symbol within a predetermined range. Then, when normal symbol display on the normal symbol display unit 44 is started, it is determined whether or not to win based on a determination random number per normal symbol. As a result of the variable display, a mode according to the determination result (In this embodiment, if it is a hit, the LED is displayed in red, and if it is off, the LED is displayed in green).

  In addition, the random number for determining the normal symbol extracted based on the fact that the game ball passes through the gate 74 and the game ball is detected by the gate switch 74a while the normal symbol display 44 performs the fluctuation display of the normal symbol is It is possible to store up to a predetermined number (four in this embodiment), and the number of determination random numbers per ordinary symbol stored is indicated by the number of lighting of the normal start memory LED 48. Specifically, the general-purpose start memory LED 48 is one LED each time a game ball is detected by the gate switch 74a when the passage of the gate 74 is effective (when the normal symbol start memory number is less than 4). The LED is turned on, and one LED that is lit is extinguished every time the normal symbol display 44 starts to display the fluctuation of the normal symbol.

  In this embodiment, when it is determined that the winning is based on the random determination per normal symbol, the normal symbol variation display is started, and after the predetermined period has elapsed, the display is stopped in a state of being lit red, By moving the solenoid 71a, the movable piece 71 is rotated to control the variable winning device 70 to be open for a predetermined period. On the other hand, if it is determined that the deviation is based on the random number determined per normal symbol, the normal symbol variation display is started, and after a predetermined period has elapsed, the display is stopped in a state in which the indicator is lit in green. Do not control to open state. Specifically, when the winning determination is made based on the normal random number per symbol determination, the variation display of the normal symbol is started, and after a predetermined period has elapsed, the display is stopped in a state in which it is lit red, and then the solenoid 71a is moved to open the movable piece 71 of the second start port 73 for a predetermined time (for example, 0.5 seconds). Then, when a predetermined period has passed, the solenoid 71a is moved again to close the movable piece 71. On the other hand, if it is determined that the deviation is based on the random number per normal symbol, the normal symbol variation display is started, and after the predetermined period has elapsed, the display is stopped in a green lighted state, and then the movable piece 71 is moved. Although the opening control is not performed, the second starting port 73 is controlled so that the game ball cannot be won, but the first starting port 72 is in a state where the game ball can be won.

  When a game ball is won at the first start port 72 or the second start port 73 and the game ball is detected by the start port switch 70a and the start port switch 70b, the special symbol display 41 changes the special symbol. If it is in a state where display can be started (for example, a state in which a big hit game is not being played, and a state in which special symbols and decorative symbols are not being displayed), the special symbol display 41 starts variable symbol display, The image display device 42 starts displaying the decorative symbols in a variable manner. If the special symbol and decorative symbol change display is stopped after a lapse of a predetermined period, and the special symbol at the time of the stop is a specific display mode (a combination of lighting of multiple light emitters that will be a big hit: jackpot symbol) The decorative symbol stop symbol (the state in which all the left, middle, and right decorative symbols are stopped) is also in a specific display mode (the same decorative symbol combination: jackpot symbol), and the control of the “hit game state” is started.

  That is, the solenoid 76a is driven, and the lower part of the front door 76 that closes the entrance of the big prize opening is turned as a fulcrum to control the big prize opening opening / closing device 75 to the open state for a predetermined time. (For example, 30 seconds) Or, a predetermined number (for example, 10) of game balls wins the big prize opening and is kept open until the count switch 75a detects it. Thereafter, the solenoid 76a is driven to stand up with the lower portion of the front door 76 as a fulcrum to close the entrance of the prize winning opening, and the prize winning opening / closing device 75 is controlled to be closed. When the open / close cycle (hereinafter also referred to as a round) from the control of the winning opening / closing device 75 to the closed state is controlled 15 times (15 rounds executed), the big hit gaming state End. As described above, when the game state is controlled to the big hit gaming state, the big winning opening is opened, and the first starting opening 72 and the second starting opening 73 are made to win the game ball in the opened large winning opening. Since it is possible to acquire a large amount of game balls in a shorter time than winning game balls, it is possible to increase the interest of the player.

  In this embodiment, the left, middle, and right decorative symbols are controlled to stop in the order of left decorative symbol → right decorative symbol → middle decorative symbol. The stop symbol of the decorative symbol is a state in which all of the left, middle and right decorative symbols are stopped and displayed by starting the variable display of the left, middle and right decorative symbols and stopping the middle decorative symbol 80b. A combination of symbols.

  In addition, when the special symbol at the time of the stop is a special mode (a combination of lighting of a plurality of light emitters that are probable big hits) among the specific display modes, the decorative symbol is also a special mode (non-probable variable design: In this embodiment, the combination of the same odd number of symbols: a probability variation symbol), and after controlling to the big hit gaming state, the probability of the next big hit gaming state increases (in this embodiment, the probability variation state is 1 / 70, 1/490 except for the probability variation state). That is, it becomes a more advantageous state for the player in the probability variation state. In the probability variation state, the variation time from the start of variation display of the special symbol on the special symbol display 41 to the stop display of the special symbol, and the variation display of the normal symbol on the normal symbol display 44 are started. Control for shortening the fluctuation time until the normal symbol is stopped from the normal state, control for increasing the probability that the result of the fluctuation display of the normal symbol on the normal symbol display 44 is “winning”, the normal symbol indicator 44. Control for extending the opening time of the movable piece 71 that is released based on the fact that the normal symbol variation display is “win” at 44 (in this embodiment, 0. 0 in the normal state). 5 seconds, 0.8 seconds in the short-time state and the probability variation state), and a control for increasing the number of times the variable winning device 70 is opened to the open state (in this embodiment, once in the normal state) , Short time And the probability change state, three times), and time reduction control and the like are performed.

  In addition, when the special symbol at the time of the stop is a non-special mode (a combination of lighting of a plurality of light emitters that are non-probable big hits) different from the special mode among the specific display modes, the stop symbol of the decorative symbol is also non- It becomes a special mode (in this embodiment, the same even symbol combination: non-probable variation symbol), and after controlling to the big hit gaming state, the special symbol display 41 is used a predetermined number of times (in this embodiment, 100 times). Control that shortens the variation time of the special symbol and the variation time of the normal symbol from the normal state until the variation display of the special symbol is executed. Time-shortening control such as control for extending the opening time of the movable piece 71 to be opened based on the fact that it has become, control for increasing the number of times the variable winning device 70 is opened to the opening state, compared to the normal state, etc. But It is the row. In the short time state, the winning probability to the second start port 73 increases until the special symbol change display is executed a predetermined number of times on the special symbol display 41, and the number of executions of the special symbol change display in the predetermined period is increased. Can be increased, so that the player is in an advantageous state. In the probability variation state described above, in addition to the time reduction control, the probability that the normal symbol change display result is “hit” on the normal symbol display 44 is increased, which is more advantageous to the player than the time reduction state. It becomes a state. The normal state is a state other than the probability fluctuation state and the short time state described above.

  As described above, in the present embodiment, three game balls are won at the first start port 72, and three game balls are won at the second start port 73 when detected by the start port switch 70a. Four game balls are paid out when detected by the mouth switch 70b. As described above, since the first starting port 72 can always win a game ball from above, if there are too many payouts for the winning of the game ball, the starting port (the first starting port 72 and the second starting port 73). ) Will be restrained (by eliminating the disadvantages on the side of the operator, etc.), and as a result, the expectation of the lottery game (determining whether or not to make a big hit game state) will be reduced, which will make the player uncomfortable I will give it. Further, if the number of payouts is too small, the number of game balls required for the lottery game increases, and as a result, excessive investment is required, resulting in a disadvantage to the player. On the other hand, the second start port 73 provides a game advantageous to the player in a short time state and a probability variation state, which will be described later, and performs an extension control of the opening time and the number of opening times of the movable piece 71, The winning probability for the second start port 73 is increased. However, if the number of payouts for winning a game ball is too small, the number of payouts for the shot ball is reduced, and the game ball is reduced in spite of an advantageous game state, which gives the player an uncomfortable feeling. Considering these events, the number of payouts (3, 4) for each of the first start port 72 and the second start port 73 is set.

  The display result of the special symbol on the special symbol display 41 corresponds to the display result of the decorative symbol on the image display device 42. That is, when it is determined that the special symbol display 41 and the image display device 42 do not make a big hit when starting the variation display of the special symbol and the decorative symbol, the special symbol display 41 and the specific display mode The LED is turned on in a different off state and the special symbol is stopped and displayed, and the display result in the off state different from the specific display mode on the image display device (outside symbol: a symbol other than the jackpot symbol, this In the embodiment, a combination of at least two types of identification information (designs) is derived.

  Further, the decorative symbols that are variably displayed on the image display device 42 are symbols for effects different from the special symbols that are variably displayed on the special symbol display 41. The contents are displayed to the player with the effect being further enhanced by using the decorative design for the effect. In other words, when the LED on the special symbol display 41 is lit and displayed in a specific display mode, the transition to the big hit gaming state is controlled. Even if the LED in the special symbol display 41 is not lit in a specific display mode, the transition control to the big hit gaming state is not performed.

  Further, in this embodiment, although it is possible to control to one type of big hit gaming state in which “15 times” is set as the number of rounds executed in the big hit gaming state, it is given to the player as the big hit gaming state. You may comprise so that it can control to the multiple types of jackpot game state from which a profit differs. For example, it may be configured to control to a plurality of types of jackpot gaming states with different numbers of rounds executed in the jackpot gaming state. In this case, after determining the big hit based on the big hit determination random number, the number of rounds to be executed in the big hit game state may be determined, or different round numbers may be set based on the big hit determination random number. It may be determined whether to control any one of the plurality of types of big hit gaming states.

  In this embodiment, the status display LED 45 is controlled to be lit in red in the above-described probability variation state, and is controlled to be lit in green in the above-described time-short state. Then, when the short-time state and the probability variation state are finished, that is, when the control to the normal state is started, and when it is controlled to the big hit gaming state, the state display LED 45 is turned off.

  In this embodiment, the above-mentioned jackpot type display LED 46 is lit while the jackpot gaming state is being executed. Specifically, depending on the type of the big hit gaming state, either one or both of the left side LED with ○ of the big hit type display LED 46 and the right LED with × is turned on. . In this embodiment, since it is possible to control only one type of jackpot gaming state, the lighting control of the jackpot type display LED 46 has no effect, but when it is configured to be controlled to a plurality of types of jackpot gaming state The type of the big hit gaming state can be grasped by controlling turning on / off the big hit type display LED 46 corresponding to a plurality of types of big hit gaming states.

  For example, as a plurality of types of big hit gaming states, the first big hit gaming state in which “7 times” is set as the number of rounds executed in the big hit gaming state, and the round number executed in the big hit gaming state is “15 times”. When the first big hit gaming state is set to be executable, the right LED (LED marked with x) of the big hit type display LED 46 is turned on during the execution of the first big hit gaming state. In addition, during the execution of the second big hit game state, the control for turning on the LED on the left side of the big hit type display LED 46 (the LED with a circle) may be executed. Thus, the pachinko machine 1 in this embodiment is configured to be compatible with a gaming machine that can be controlled to a plurality of types of big hit gaming states.

  Next, various control processes executed according to the game progress of the pachinko machine 1 will be described with reference to FIGS. FIG. 6 is a flowchart showing the start winning process executed on the main board. FIG. 7 is a list showing random numbers updated on the main board 101. FIG. 8 is a flowchart showing special symbol processing executed on the main board. FIG. 9 is a flowchart showing a big hit determination process as a subroutine of the special symbol variation process. FIG. 10 is a flowchart showing a variation display pattern setting process which is a subroutine of the special symbol variation process. Note that these processes show a part of the processes executed by the CPU 102 mounted on the main board 101 at a predetermined timing (in this embodiment, every 4 ms) in accordance with the game control program stored in the ROM 103. Is.

  When a game ball that is launched by the launching device 135 and flows down from the upper part to the lower part of the game area 12 wins the first start port 72 or the second start port 73, the start winning process shown in FIG. 6 is executed. In the start winning process, it is first determined whether or not a game ball has won the first start opening 72 and the second start opening 73 (step S1). Specifically, it is determined whether or not a detection signal is output from the start port switches 70a and 70b, and when a detection signal is output from the start port switches 70a and 70b, it is determined that a prize has been won (YES), If no detection signal is output from the start port switches 70a and 70b, it is determined that no winning is made (NO). When it is determined that a game ball has won the first start port 72 and the second start port 73, various random numbers (for example, a big hit determination random number, a probability variation determination random number, a reach determination random number, a variable display pattern random number, etc., which will be described later) And whether or not the value of the reserved ball number counter provided in the RAM 104 is smaller than 4 which is the upper limit value (step S2). If the reserved ball number counter is less than the upper limit value (YES), the reserved memory storage process is executed (step S3).

  In the on-hold storage storing process, the process of adding “1” to the on-hold ball number counter and the lighting display mode (number of lamps to be turned on) of the special figure start memory lamp 47 are changed in accordance with the addition of the on-hold ball number counter. A process and a process of storing the obtained random number value in the storage area of the start winning memory provided in the RAM 104 in correspondence with the count value of the reserved ball number counter are performed. Note that if the game ball has not won the first start port 72 and the second start port 73 in step S1, the start winning process is terminated without executing the following process. If the number of held balls is greater than or equal to the upper limit value in step S2, the random value acquired in step S1 is discarded, and the start winning process is terminated without executing the following process. It should be noted that when it is determined in step S1 that a game ball has won the first start port 72 and the second start port 73, various random numbers are not acquired, and in step S2, the retained ball number counter is less than the upper limit value. Various random numbers may be acquired after the determination.

  Here, various random numbers updated at predetermined timing (in this embodiment, every 4 ms) by the CPU 102 mounted on the main board 101 include a jackpot determination random number, a probability variation determination random number, a reach, as shown in FIG. There are a determination random number, a variation display pattern random number, a normal determination random number per symbol, and the like. The big hit determination random number is a random number for determining whether or not to generate a big hit gaming state (big hit determination). When it is determined that the big hit gaming state is generated in the big hit determination, the probability variation determination random number is changed to a probability fluctuation state after the big hit gaming state is finished based on whether or not it matches a determination value set in a probability variation determination table described later. It is a random number for determining whether or not the probability variation big hit to be controlled is determined (probability variation determination). The reach determination random number is a random number for determining (reach determination) whether or not to make a detachment with a reach mode when it is determined that the big hit gaming state is not generated in the big hit determination. The variation display pattern random number is a random number for determining the variation display pattern of the special symbol and the decorative symbol displayed on the special symbol display 41. The normal symbol determination random number is a random number for determining whether or not the normal symbol display result is a hit (normal symbol determination). The random numbers updated on the main board 101 are not limited to those described above, and are random numbers for determining the initial value of the big hit determination random number that starts counting next when the counter that updates the big hit determination random number makes one round. Etc.

  In addition, the jackpot determination random number, the probability variation determination random number, the reach determination random number, and the variation display pattern random number described above are acquired in step S1 of the start winning process and stored in the start winning memory storage area provided in the RAM 104 in step S3. Stored in correspondence with the count value of the reserved ball number counter. In addition, the random number for normal symbol determination is acquired when the game ball passes through the gate 74 and is detected by the gate switch 74a, and the number of random numbers for normal symbol determination stored in the RAM 104 is the upper limit value ( In this embodiment, if it is less than 4), it is stored in the RAM 104.

  In the special symbol process shown in FIG. 8, first, it is determined whether or not the value of the reserved ball number counter is 0 (step S11). When the value of the reserved ball number counter is 0, it is determined that the big hit determination random number is not stored in the RAM 104, that is, the condition for starting the special symbol variation display is not satisfied, and the step S15 described later is performed as it is. Migrate to On the other hand, when the value of the reserved ball number counter is not 0, it is determined that the condition for starting the variable symbol display is satisfied, and the variable symbol decorative display can be started. It is determined whether or not there is a state in which a big hit game is not being played and a state in which special symbol variation is not being displayed (step S12). When it is not possible to start the variable display of the special symbol (decorated symbol), the process proceeds to step S15.

  When it is possible to start the variable display of the special symbol (decorated symbol) in step S12, the hold memory transfer process is executed (step S13). In the hold memory transfer process, the process of subtracting 1 from the hold ball number counter, and after shifting various random numbers stored in the save area of the start winning memory provided in the RAM 104, the hold memory counter in the save area of the start winning memory is stored. And reading various random numbers (big hit determination random numbers, etc.) stored in the storage area corresponding to 0. That is, various random numbers stored in the storage area corresponding to n (n = 1, 2, 3, 4) of the reserved ball number counter in the storage area of the start winning memory are stored in the storage area of the start winning memory. The counter is stored in a storage area corresponding to n-1 (n = 0, 1, 2, 3).

  Thereafter, special symbol variation processing (step S14), special symbol variation processing (step S15), information output processing (step S16), and jackpot game processing (step S17) are sequentially executed. In the special symbol variation process (step S14), a jackpot determination process and a variation display pattern setting process, which will be described later, are performed, and variation control of the special symbol and the decorative symbol is performed based on the variation display pattern determined in the variation display pattern setting process Start and set the fluctuation time in the fluctuation timer. In the special symbol variation processing (step S15), when the special symbol variation display on the special symbol display 41 is started, the variation time set in the variation timer is monitored, and the variation set in the variation timer is monitored. When time elapses (the variation timer expires), a process of stopping (determining) the variation display of the specific symbol and the decorative symbol is performed. In the information output process (step S16), a drive signal related to the special symbol variation display determined in the special symbol variation process (step S14) and the special symbol variation process (step S15) is output to the special symbol display 41. Then, a process of transmitting various information related to the decorative symbol variation display to the sub-integrated board 111 is performed. In the big hit game process (step S17), it is determined whether or not a big hit flag, which will be described later, is in an ON state. If the big hit flag is in the ON state, a mode according to the type of hit (either a probable variable big hit or a non-probable big hit) Then, the control of the big hit game state, that is, the special winning opening opening / closing device 75 is controlled to be opened a predetermined number of times to open the special winning opening.

  In the big hit determination process shown in FIG. 9, first, it is determined whether or not a probability variation state flag set in step S37 described later is in an ON state (step S31). If the probability variation status flag is ON, a probability variation big hit determination table (not shown) is selected (step S32). If the probability variation status flag is not ON (if OFF), the non-probability variation big hit determination table is selected. (Not shown) is selected (step S33). In the probability change big hit determination table, 14 determination values among 980 big hit determination random numbers from 0 to 979 are set, and the big hit probability, which is the probability of a big hit, is 1/70. On the other hand, in the normal jackpot determination table, two determination values are set out of 980 jackpot determination random numbers from 0 to 979, and the jackpot probability is 1/490.

  Then, the decision value set in the probability change big hit determination table selected in steps S32 and S33 or the normal time big hit determination table matches the value of the big hit determination random number read in the hold storage transition processing in step S13. Whether or not to make a big hit is determined depending on whether or not to do (step S34). The judgment value set in the probability change jackpot determination table selected in steps S32 and S33 or the normal time jackpot determination table, and the value of the jackpot determination random number read in the hold storage transition process in step S13 (starts the fluctuation display) When it is determined that a big hit is made based on the fact that the big hit determination random number to match) is set to ON (step S35), a probability variation determination table (not shown) in which a predetermined determination value is set is set. ) To determine whether or not to make a probable big hit (step S36). Specifically, whether or not to make a probable big hit based on whether or not the value of the probable change determination random number read in the hold storage transition process in step S13 matches the determination value set in the probability change determination table. judge. In this embodiment, the probability variation entry rate (the ratio of the big hits as the probability variation big hit) is 2/3, that is, six decision values among nine probability variation determination random numbers from 0 to 8. Is set in the probability variation determination table.

  If it is determined in step S36 that the determination value set in the probability variation determination table and the value of the probability variation determination random number read in the hold storage shift processing in step S13 match, the probability variation state is determined. If it is determined that the flag is in the ON state (however, if the probability variation state flag is already in the ON state, the ON state is continued) (step S37), and that the big hit is not the probability variation big hit (non-probability variable big hit) The probability change state flag is set to the OFF state (however, if the probability change state flag is already OFF, the OFF state is continued) (step S38). On the other hand, when it is determined in step S34 that a big hit is not made (defeated), the process is terminated without executing the following process. The ON / OFF states of the big hit flag and the probability variation state flag are stored in the RAM 104. In addition, a value of “0” is set when the big hit flag and the probability change state flag are OFF, and a value of “1” is set when the big hit flag and the probability change state flag are ON.

  In the variation display pattern setting process shown in FIG. 10, first, as a result of the present variation display, it is determined whether or not a big hit is made, that is, whether or not the big hit flag set in step S36 of the big hit determination process is ON. It discriminate | determines (step S41). If the big hit flag is in the ON state, the big hit hour variation display pattern table (not shown) showing a mode for deriving the big hit symbol is selected (step S42). On the other hand, if the big hit flag is not in the ON state (if it is in the OFF state), the determination value set in the reach determination table in which the predetermined determination value is set, and the reach determination read in the hold storage transition process in step S13 Whether or not to reach is determined by whether or not the value of the random number matches (step S44). In the reach determination table, the reach probability (reach mode ratio) is 1 / 12.5, that is, two determination values out of 25 reach determination random numbers from 0 to 24 are reach determination. Set in the table.

  When it is determined in step S44 that the reach mode is selected, a reach-time variation display pattern table (not shown) showing a mode for deriving an outlier symbol accompanying the reach mode is selected (step S45), and the reach mode is selected in step S44. When it is determined not to be selected, a loss variation display pattern table (not shown) showing a mode for deriving a loss symbol without a reach mode is selected (step S46). Then, the judgment value set in any one of the variation display pattern tables of the big hit variation display pattern table, the reach variation display pattern table, or the loss variation display pattern table selected in Steps S42, 45, and 46. And a variable display pattern that matches the value of the random number of the variable display pattern read out in the hold storage transition process in step S13 is determined (step S43).

  The deviation variation display pattern table includes a table in which only a variation display pattern of normal variation described later is set, and a table in which only a variation display pattern of a shortened variation having a variation time shorter than the normal variation is set. When the above-mentioned time-shortening control is being executed, a table in which only the variation display pattern of the shortening variation is selected is selected. When the time-shortening control is not being executed, only a normal variation-displaying pattern is set. Is selected. That is, when the time reduction control is not executed, it is determined as the fluctuation display pattern of the normal fluctuation, and when the time reduction control is executed, it is determined as the fluctuation display pattern of the shortening fluctuation.

  Next, the variable display pattern command is set as a display command for designating the variable display pattern determined in step S43 (step S47). By setting the variable display pattern command in step S47, it is transmitted to the sub-integrated board 111 in the information output process (step S16). Further, when the variable display pattern command is output to the sub-integrated board 111 in the information output process (step S16), a drive signal is output to the special symbol display 41 to start the variable symbol variable display. Note that the sub-integrated board 111 performs control for starting the decorative display variable display based on the reception of the variable display pattern.

  Further, the variation time of the special symbol is set substantially coincident with the effect time included in the variation display pattern transmitted to the sub-integrated board 111, and has an effect time corresponding to the variation time of the special symbol in step S43. The variable display pattern is determined. Note that the variation time of the special symbol and the effect time included in the variation display pattern may not coincide with each other. In step S43, processing for setting the variation time of the special symbol to the variation timer provided in the RAM 104 mounted on the main board 101 is also performed. This variation timer starts when a variation pattern command is transmitted to the sub-integrated board 111 in the information output process (step S16), and a special symbol indicator is displayed when the variation timer times out in the special symbol variation processing (step S15). The CPU 102 outputs a drive signal to 41 so that the CPU 102 stops the special symbol variation display, and transmits a display command to the sub-integrated board 111 to stop the decorative symbol variation display. Note that the sub-integrated board 111 performs control for stopping and displaying the decorative symbols based on the reception of the display command for instructing the stop of the decorative symbol variation display.

  Further, the CPU 102 checks whether or not the probability variation state flag is set (step S48). When the probability variation state flag is set, the CPU 102 sets a probability variation big hit command which is a display command indicating that the probability variation big hit is set. (Step S49). By setting the probability variation jackpot command in step S49, the command is transmitted to the sub integrated substrate 111 together with the variation display pattern command. As a result, the integrated CPU 112 mounted on the sub-integrated board 111 can recognize that it is a probable big hit.

  Next, the configuration of the above-described center unit 40 on the stage 50 will be described in detail with reference to FIGS. FIG. 11 is a perspective view of the game board 4 as viewed from the upper right.

  As shown in FIG. 11, the swing path member 43 provided in the upper left part of the front decorative body 80 and the front decorative body are provided behind the left edge and the right edge of the center unit 40 (on the back side of the pachinko machine 1). A ball guiding member 65 for guiding the game ball that has entered the ball passage member 49 provided at the upper right portion of 80 to the stage 50 of the game board 4 is located.

  In addition, the ball guide member 65 includes a branch passage 67 in which a downstream portion (a branch portion 673, which will be described later) branches into two branches and guides the game ball to one of the branches, and the swing passage member 43 and the ball passage member 49 are branched passages. The game ball that has entered the swing passage member 43 and the ball passage member 49 is discharged to the connection passage 66 and then rolls through the connection passage 66 to cause a ball guide member 65. It is discharged from one of the upper guide port 68 and the lower guide port 69 that are outlets that flow into the branch passage 67 and flow down the branch passage 67 and discharge to the outside of the ball guide member 65.

  FIG. 12 shows a cross-sectional view of the ball guide member 65. As shown in FIG. 12, inside the ball guiding member 65, a branch passage 67 is formed in a passage shape having a width dimension equivalent to one game ball. Further, the branch passage 67 is bent and formed with a predetermined width dimension (a width dimension equal to or smaller than the width dimension of the stage member 50a), and the game ball is inserted into the depth direction (left side direction in the figure) and the near side direction (illustration side) of the pachinko machine 1. A bending portion 671 that flows down while rolling in the right direction), a feeding portion 672 that is formed with a width of approximately one gaming ball and flows the gaming ball that has flowed down the bending portion 671 substantially vertically, A bifurcating portion 673 that is bifurcated and distributed to one of the upper guide port 68 and the lower guide port 69. Note that the branch passage 67 in the present embodiment only needs to have at least the feeding portion 672 formed with a width dimension for one game ball, and the bent portion 671 and the branch portion 673 have a width dimension for one game ball. It does not have to be formed.

  The bent portion 671 is composed of a single ball passage in which a plurality of layers of passages are connected at the end thereof, and the game ball Q1 that has entered the swing passage member 43 and the ball passage member 49 passes through the connection passage 66, It is discharged from the entrance of the sphere guide member 65 into the branch passage 67. The game ball Q2 released to the branch passage 67 rolls in the depth direction of the pachinko machine 1 at the bent portion 671, collides with the inner wall of the branch passage 67, weakens its momentum (entry speed), and flows down. Then, it is guided toward the front side of the pachinko machine 1. Thus, in this embodiment, the branch passage 67 is bent and formed with a predetermined distance width (passage width in the left-right direction in FIG. 12), so that the game ball that rolls in the bent portion 671 has its momentum (rolling force). It is formed so as to collide with the inner wall of the branch passage 67 before the dynamic speed) is strengthened and weaken its momentum, and can suppress or stabilize the momentum (rolling speed) of the game ball that has entered the branch passage 67 .

  The game ball guided in the forward direction (rightward in FIG. 12) after flowing down the bent portion 671 again collides with the inner wall of the branch passage 67 and flows down substantially directly (vertically) to the feeding portion. Enter 672. The sending-in part 672 has a width dimension corresponding to one game ball, regulates the game ball, flows down substantially right (vertically), and sends it to the branch part 673. The branching portion 673 is provided with a branching member 67a that protrudes from the back surface (surface far from the stage 50) where the ball guiding member 65 is not exposed at the approximate center of the width in the depth direction of the feeding portion 672. ing. Then, the game ball Q3 sent from the sending part 672 collides (abuts) the center part with the surface of the branching member 67a perpendicularly, and is led to one of the upper guide port 68 or the lower guide port 69. A game ball Q4 guided to the upper guide port 68 falls on an upper rail 52 described later and rolls toward the circular guide portion 54, and a game ball Q5 guided to the lower guide port 69 is described later. It falls on the lower rail 53 and rolls toward the circular guiding portion 54.

  The upper surface of the branch member 67a (the surface on which the game ball flowing down the branch passage 67 abuts) is formed substantially flat, and the branch portion 673 is divided into two regions by the branch member 67a. With this configuration, the game ball flowing down the branch passage 67 collides with the branch member 67a and is irregularly guided to one of the upper guide port 68 and the lower guide port 69. It is possible to prevent the distribution ratio with the rail 53 from being biased. Further, the game ball Q3 that is fed from the feed portion 672 and abuts against the branch member 67a has a space of one or more game balls in the left-right direction (so as to have play), that is, the game ball Q3 Since the branch portion 673 is formed so as to increase the degree of freedom, it is possible to prevent the game ball that has come into contact with the branch member 67a from being caught in the branch passage 67 and causing a ball clogging.

  Further, the game ball flowing down the branch passage 67 inevitably collides with the branch member 67a. In addition, the momentum (approach speed) is weakened by rolling in the depth direction and the near side of the pachinko machine 1 in the branch passage 67 and colliding with the inner wall of the branch passage 67, but after being weakened by the branch passage 67 Even if the momentum is above a certain level, the momentum can be completely suppressed by colliding with the branching member 67a. In other words, the game ball that has flowed down the branch passage 67 and guided in the front direction of the pachinko machine 1 again collides with the inner wall of the branch passage 67 and flows down substantially below. And since it collides with the upper part of the branch member 67a substantially perpendicularly, it becomes possible to stop the momentum completely.

  Further, in this embodiment, the momentum (flowing speed) of the game ball is suppressed by the branch passage 67 and the momentum (flowing speed) of the game ball is weakened before it collides with the branching member 67a. Can be reduced, and the branching member 67a can be extended. Further, in this embodiment, the game ball flowing down the branch passage 67 collides with the upper part of the branch member 67a. However, the branch member 67a has a narrow vertically long shape (in FIG. The durability of the branching member 67a is enhanced by forming the member with a large width dimension in the direction.

  Further, the branch member 67a is provided so that the height position of the upper surface of the branch member 67a and the height positions of the upper rail 52 and the lower rail 53 are within a predetermined width dimension (for example, within 2 cm). Yes. That is, the game ball Q3 that is in contact with the branch member 67a falls from the branch member 67a onto the upper rail 52 or the lower rail 53. At this time, the greater the difference between the height position of the upper surface of the branching member 67a and the height positions of the upper rail 52 and the lower rail 53, the greater the impact applied to the upper rail 52 and the lower rail 53, and the upper rail. 52 and the lower rail 53 become easy to break. In this embodiment, the load on the upper rail 52 and the lower rail 53 can be reduced by reducing the difference between the height position of the upper surface of the branching member 67a and the height positions of the upper rail 52 and the lower rail 53, It becomes possible to make the upper rail 52 and the lower rail 53 last longer.

  FIG. 13 is a perspective view of the game board 4 as viewed from the front upper side. Further, as shown in FIGS. 11 to 13, the center unit 40 is provided with a stage 50 having a predetermined width in the depth direction from the lower outer wall of the front decorative body 80 so as to be positioned in front of and below the image display device 42. It has been. In the stage 50, the game balls introduced from the swing passage member 43 provided at the upper left portion of the front decorative body 80 and the ball passage member 49 provided at the lower portion of the rotating accessory 61 of the center unit 40 roll. A possible area is formed. Further, the surface of the stage 50 is inclined at a predetermined angle toward the front side of the pachinko machine, and is configured to discharge game balls that roll on the stage 50 toward the front side of the pachinko machine.

  Further, a guide passage 58 having a passage shape for one game ball is formed at the center of the stage 50. Further, the guide passage 58 is connected to the discharge port 51 formed at the center of the lower outer wall of the front decorative body 80 by descending below the stage 50 and bending and extending from there to the front side. The discharge port 51 is formed directly above the variable winning device 70 on the lower outer wall of the front decorative body 80, and the game ball embedded in the guide passage 58 is guided to the discharge port 51 and discharged right below the discharge port 51. This makes it easier to win the first start opening 72. The discharge port 51 is disposed below the discharge stage 80a formed at the lower edge of the front decorative body 80 (position closer to the first start port 72 than the discharge stage 80a), and the guide passage 58 and It is formed in an opening shape for one connected game ball. For this reason, the game ball discharged from the discharge port 51 is likely to win the first start port 72 with high probability (probability close to 100%).

  In addition, a plurality of support members 57 having a predetermined height (in this embodiment, a height equal to or greater than the diameter dimension of the game ball) are formed on the surface of the stage 50 so as to protrude. A hollow guide portion 54 (which forms the shape of an annular sphere guide passage) is formed in the front side of the pachinko machine 1 at the upper part of the plurality of support members 57 that are formed so as to protrude substantially in the center in the left-right direction of the stage 50. It is placed so as to be inclined at a predetermined angle. The circular guide portion 54 has wall portions 54a (both side wall portions as spherical guide passages) that protrude upward from the surface of the circular guide portion 54 along the outer periphery and the inner periphery. It has the groove part 54b (bottom part as a bulb | ball guide path) enclosed by the wall part 54a. Further, the support member 57 has a columnar shape, and the diameter dimension of the cross section thereof is formed with a value smaller than the diameter dimension of the game ball. Thereby, the game ball rolling on the stage 50 is discharged in the front direction of the pachinko machine 1 without stopping on the back side of the support member 57.

  Further, the groove portion 54b of the circular guiding portion 54 has a predetermined width (in this embodiment, a width wider than the diameter dimension of the game ball), and the game ball can roll. In this embodiment, the groove portion 54b is formed so as to have a width sufficiently wider than the diameter size of the game ball, and the degree of freedom of the game ball in the circular guide portion 54 is increased, whereby the game ball in the circular guide portion 54 is increased. Each rolling can have a change. Further, in this embodiment, the outer peripheral and inner peripheral wall portions 54a of the circular guide portion 54 are formed to protrude upward from the upper surface of the circular guide portion 54 so as to have a height smaller than the diameter dimension of the game ball, Almost the entire game ball rolling in the groove 54b of the circular guide portion 54 is visible.

  In this embodiment, the circular guide portion 54 is placed so as to incline at a predetermined angle toward the front side of the pachinko machine. However, the wall portion 54a protrudes along the outer periphery of the circular guide portion 54. The game ball that rolls in the groove 54b of the circular guide portion 54 comes into contact with the outer periphery and is bounced inward, and does not fall from the circular guide portion 54 toward the front side of the pachinko machine. That is, the wall portion 54a is a fall prevention means for preventing the game ball from dropping from the circular guide portion 54. Further, in this embodiment, the wall portion 54a is formed to protrude so as to have a height smaller than the diameter size of the game ball, so that the game ball rolling on the groove portion 54b can be visually recognized. By forming it with a transparent resin (for example, acrylic resin such as ABS resin), the height of the wall portion 54a from the upper surface of the circular guiding portion 54 (groove portion 54b) is higher than the diameter of the game ball. The protrusion may be formed.

  Moreover, the wall part 54a of the inner periphery of the circular guide part 54 has a notch part from which a part is cut off. In this embodiment, the circular guide portion 54 has a notch portion 54c drilled in a part on the inner peripheral back side and a notch portion 54d drilled in a part on the front side of the inner periphery. The notch 54d on the front side has a wall 54a cut out over a wider area than the notch 54c on the inner peripheral back side, and the groove 54b corresponding to the notch 54d on the inner peripheral front side (the inner front side of the groove 54b). A portion of the notch 54d located on the front side of the pachinko machine 1) is inclined to the back side of the pachinko machine 1, and the game ball is discharged toward the notch 54d on the front side of the inner periphery. The circular guide portion 54 is placed such that the guide passage 58 is positioned below the hollow portion, and an upper guide passage 55 that connects the notch portion 54c on the back side of the circular guide portion 54 and the guide passage 58 is provided. A lower guide path 56 that connects the guide passage 58 and a part of the notch 54 d on the front side of the circular guide 54 is formed.

  Further, on both the left and right sides of the depth direction in the depth direction of the circular guiding portion 54, the circular guiding portion 54 is placed on the upper portion of the support member 57 formed to project from the stage 50, and the upper guiding opening 68 of the ball guiding member 65 and the circular guiding portion. 54 is connected to the upper rail 52, and the left and right portions of the circular guide portion 54 in the depth direction are placed on the upper portion of the support member 57 formed to protrude from the stage 50, thereby guiding the ball. A lower rail 53 that bridges the lower guide port 69 of the member 65 and the circular guide portion 54 is connected. The upstream ends of the upper rail 52 and the lower rail 53 are installed close to each other with the branch member 67a interposed therebetween (see FIG. 11).

  Further, as shown in FIG. 14, the upper rail 52 and the lower rail 53 are each formed of a bar-shaped rail member 59a that forms both side wall portions of the guide passage, and a bottom portion of the guide passage to form the upper rail 52 and the lower rail. And a sleeper member 59b that increases the strength of the rail 53 and keeps the interval between the rail members 59a constant. In this embodiment, the sleeper member 59b is formed with a width smaller than the diameter dimension of the game ball so that the interval between the rail members 59a is smaller than the diameter dimension of the game ball, and the upper rail 52 and the lower rail 53 are The rolling game ball flows down while being held by the rail member 59a. Accordingly, the game balls rolling on the upper rail 52 and the lower rail 53 are visible.

  The upper rail 52 and the lower rail 53 are provided so as to have a predetermined downward inclination from the upper guide port 68 and the lower guide port 69 toward the circular guide portion 54. Further, in this embodiment, since the game ball is sandwiched by the rail member 59a and flows down, rolling in a direction other than the traveling direction, that is, the direction flowing down to the circular guiding portion 54 is restricted, and one direction, that is, circular Rolling in the direction of flowing down to the guiding portion 54 is permitted.

  The downstream portion of the upper rail 52 and the lower rail 53 (the side close to the circular guide portion 54) is curved so that the rolling game ball is fed along the curvature of the circular guide portion 54. Therefore, the game balls rolling on the upper rail 52 and the lower rail 53 are guided to the circular guide portion 54 without killing the momentum.

  It should be noted that the interval between the rail members 59a may be equal to or greater than the diameter of the game balls so that the game balls roll on the sleeper members 59b. By projecting and forming so as to have a height that is smaller than the diameter dimension of the game ball, the game ball rolling on the sleeper member 59b may be visible, and the rail member 59a may be made of a transparent resin (for example, ABS resin). It may be configured such that the game ball can be visually recognized without being limited by the height of the rail member 59a.

  In this embodiment, the circular guide portion 54, the upper rail 52, and the lower rail 53 are placed on the plurality of support members 57 having a height equal to or larger than the diameter of the game ball from the upper surface of the stage 50. The game balls that roll on the circular guide portion 54, the upper rail 52, and the lower rail 53 do not come into contact with the game balls that roll on the stage 50. Therefore, the game balls rolling on the circular guide portion 54, the upper rail 52, and the lower rail 53 are bounced by the game balls rolling on the stage 50 and fall onto the stage 50, and the circular guide portion 54, the upper rail 52 and the lowering of the interest rate of the player by lowering the winning rate to the starting opening (the first starting opening 72 and the second starting opening 73) when the lower rail 53 is rolling. it can.

  The game balls that have entered the swing passage member 43 provided at the upper left portion of the front decorative body 80 and the ball passage member 49 provided at the lower portion of the rotating member 61 of the center unit 40 are connected to the ball guide member 65. It is guided to the branch passage 67 by the passage 66. Then, the game ball flowing down the branch passage 67 and discharged from the upper guide port 68 to the upstream end of the upper rail 52 rolls on the upper rail 52 and is guided to the groove portion 54b of the circular guide portion 54 to be guided to the lower guide. The game ball discharged from the opening 69 to the upstream end of the lower rail 53 rolls on the lower rail 53 and is guided to the groove portion 54 b of the circular guide portion 54. In this way, the game ball guided to the circular guide portion 54 rolls on the groove portion 54 b, falls from one of the cutout portions 54 c and 54 d of the circular guide portion 54, and is discharged from the circular guide portion 54.

  In addition, the game ball discharged from the notch 54 c on the inner peripheral back side of the circular guide portion 54 is guided to the guide passage 58 through the upper guide passage 55. On the other hand, the game balls discharged from the notch 54d on the front side of the inner periphery can be guided to the guide passage 58 through the lower guide path 56, but the lower guide path 56 is formed narrower than the notch 54d. Therefore, a part of the game balls are not guided to the guide passage 58, but fall onto the surface of the stage 50, roll in the forward direction of the pachinko machine 1, and are discharged from the discharge stage 80a. The game ball that has entered the guide passage 58 is guided to the discharge port 51 formed in the front decorative body 80 and discharged.

  Here, the ball flow of the game ball from the circular guiding portion 54 will be described with reference to FIG. FIG. 14 is a longitudinal sectional view showing the circular guide portion 54. As shown in FIG. 14, when the game ball that has flowed down the upper rail 52 or the lower rail 53 is sent to the circular guide portion 54, the game ball rolls on the circular guide portion 54, thereby causing the circular guide portion 54 to move. It moves by rotating along the passage shape (annular). Thereafter, when the rotational speed of the game ball is decelerated, the game ball falls from one of the notches 54c and 54d formed in the circular guide portion 54 and is discharged from the circular guide portion 54. The game ball P1 discharged from the inner peripheral rear cutout 54c enters the guide passage 58 through the upper guide passage 55, passes through the guide passage 58, and is discharged from the discharge port 51 to the game area 12 again. As described above, the discharge port 51 is formed directly above the variable prize-winning device 70, and thereby the game ball discharged from the discharge port 51, that is, the game discharged from the notch 54c on the inner peripheral back side. The ball P1 has a high winning rate for the start port (first start port 72) (probability close to 100%).

  Next, the flow of game balls discharged from the notch 54d on the inner circumference front side will be described. The game balls discharged from the notch 54d on the front side of the inner periphery are divided into those that flow down on the lower guideway 56 and those that fall off the lower guideway 56 and fall on the stage 50 as they are. The game ball P2 flowing down on the lower guide path 56 enters the guide passage 58 in the same manner as the game ball flowing down on the upper guide path 55 (the game ball P1 discharged from the notch 54c on the inner peripheral back side), It passes through the guide passage 58 and is discharged from the discharge port 51 to the game area 12 again. As a result, the game ball P2 that is discharged from the notch 54d on the front side of the inner circumference and flows down on the lower guide path 56 has a high winning rate for the starting port (first starting port 72) (probability of nearly 100%). It has become. On the other hand, the game ball P3 that has fallen off the lower guide path 56 and dropped onto the stage 50 rolls on the stage 50 toward the front of the pachinko machine 1 and again enters the game area 12 from the discharge stage 80a having a wide ball discharge portion. Discharged. Therefore, the game ball P3 that has been discharged from the notch 54d on the front side of the inner periphery and then dropped onto the stage 50 from the lower guiding path 56 is discharged from the discharge port 51 to the game area 12 again. The winning rate to the starting port (the first starting port 72 or the second starting port 73) is lower than that of P2.

  By the way, in the configuration of the stage 50 as described above, the game balls rolling on the stage 50 are not only the game balls that have fallen on the stage 50 after falling off the lower guide path 56, but also the game area due to the collision with the obstacle nail. The game ball that jumps up from 12 to the stage 50 also rolls. That is, the game ball flowing down the game area 12 below the discharge stage 80a collides with the obstacle nail, jumps up onto the stage 50 (including the discharge stage 80a), rolls the stage 50, and again discharges the stage 80a (ball discharge portion). ) May be discharged to the game area 12. For this reason, when the game ball rolling on the circular guiding portion 54 is detached from the lower guide path 56 and falls on the stage 50, the game ball (P3) is bounced by the game ball jumped up on the stage 50. There is. Therefore, the discharge direction is changed by the collision of the game ball P3 discharged from the discharge stage 80a toward the first start port 72 and the second start port 73 with the jumped game ball, and the start port (the first start port 72 or the first start port 72 or the second start port 73). There is a case where a situation occurs in which there is no possibility of winning at the 2 start opening 73). On the other hand, when the game ball rolling on the circular guide portion 54 passes through the upper guide path 55 or the lower guide path 56 and then is discharged from the discharge port 51 to the game area 12 through the guide path 58, the game The balls (P1, P2) are discharged to the game area 12 without being hit by the game balls that have jumped up onto the stage 50. For this reason, the game balls P1 and P2 discharged toward the first start port 72 do not collide with the game balls that have jumped up, and therefore win the start port (the first start port 72 or the second start port 73). There is no case where the game balls P1 and P2 are discharged in a direction where there is no possibility of doing so.

  In this embodiment, the height position of the upstream end portion (upper guide port 68) of the upper rail 52 is arranged higher than that of the lower rail 53 (lower guide port 69). In other words, the upper rail 52 has a larger inclination angle than the lower rail 53. For this reason, the game ball branched and guided to the upper guide port 68 side by the branch passage 67 flows down on the upper rail 52 having a large inclination angle, and is vigorously sent to the circular guide portion 54. On the other hand, the game ball branched and guided to the lower guide port 69 side by the branch passage 67 flows down on the lower rail 53 having a small inclination angle, so that the momentum is suppressed and the game ball is sent to the circular guide portion 54. Therefore, a game ball that has flowed down on the upper rail 52 rolls on the circular guide portion 54 (moving width: along the outer periphery of the circular guide portion 54) compared to a game ball that has flowed down on the lower rail 53. The number of rotations that move) increases. Thus, by branching the guiding direction of the game ball by the branch passage 67 (upper rail 52 or lower rail 53), the momentum (flowing speed) of the game ball sent to the circular guide portion 54 can be made different. A change can be made in the mode of the sphere flow on the guide portion 54.

  In this embodiment, the upstream end of the upper rail 52 at the back position in the depth direction of the circular guide portion 54 (the side far from the player facing the front of the pachinko machine 1) is connected to the upstream end of the lower rail 53. Since the height position from the surface of the stage 50 is increased, the lower rail 53 does not hinder the viewing of the game ball rolling on the upper rail 53 arranged at the depth position in the depth direction of the stage 50. Even when the game ball rolls on the upper rail 52, the player's interest is not lowered.

  Further, as described above, the momentum of the game ball that has entered from the swing passage member 43 and the ball passage member 49 is completely suppressed, and the upper rail 52 at the upper guide port 68 or the lower rail at the lower guide port 69. 53 to the upstream end. Further, since the upper rail 52 and the lower rail 53 are provided so as to have a predetermined downward slope from the upstream end (the upper guide port 68 and the lower guide port 69) toward the circular guide portion 54, the upper rail 52 and the lower rail 53 are provided. The game balls are energized by each and sent to the circular guiding portion 54 with a predetermined momentum. Therefore, it is possible to sufficiently roll the game ball with the circular guide portion 54 without causing the momentum (entry speed) of the game ball entering the swing path member 43 and the ball path member 49, and the performance can be improved. Can fully demonstrate. That is, the rolling width of the game ball in the circular guiding portion 54 is caused only by the momentum (rolling speed) biased by the upper rail 52 and the lower rail 53, and enters the swinging passage member 43 and the passage member 49. Even when the momentum of the game ball to be played is weak (the approach speed is slow), the movement width (the number of rotations of the game ball) in the circular guiding portion 54 is not reduced due to the influence.

  In this embodiment, the circular guiding portion 54 is formed of a hollow circular member, and a game ball that rolls on the circular guiding portion 54 is dropped from one of the cutout portions 54c and 54d, whereby the guide passage 58 or the stage is formed. The circular guide portion 54 is formed into a circular shape (not hollow) having a plurality of holes, and one of the plurality of holes is communicated with the guide passage 58, and the other holes are guided to the guide passage 58. You may make it form so that it may not communicate with. That is, the circular guiding portion 54 may be formed in a croon shape so that the game ball enters the guide passage 58 only when the game ball falls into the hole communicating with the guide passage 58.

  Further, when the initial velocity of the game ball in the swing passage member 43 provided in the upper left portion of the front decorative body and the ball passage member 49 provided in the upper right portion of the front decorative body 43 is high, the groove portion of the circular guide portion 54 Although the movement width of the game ball in 54b is further widened, the opportunity to go around the groove portion 54b of the circular guide portion 54 and be guided to the upper guide passage 55 and the lower guide passage 56 is increased. It is possible to improve a sense of expectation for winning a prize at (first start port 72 or second start port 73).

  Further, a special figure start memory lamp 47 is formed on the surface of the stage 50 so as to protrude. In this embodiment, a member shaped like a bell is formed at the tip, and a lamp is built in the member. Further, in this embodiment, the special figure start memory lamps 47 are two on the left front side of the stage 50, on the front side of the pachinko machine 1 with respect to the lower rail 53, and on the right front part of the stage 50. Yes, a total of four protrusions are formed, two at the position closer to the front side of the pachinko machine 1 than the lower rail 53 so that the heights of the bells imaged at the tip of the special figure start memory lamp 47 all coincide. Formed.

  Next, with reference to FIG. 15, the rotating accessory 61 provided in the upper right part of the front surface of the center unit 40 will be described. FIG. 15 is a perspective view of the rotating unit 60 including the rotating accessory 61 as viewed from the upper right. As shown in FIG. 4, the rotating accessory 61 in this embodiment includes LEDs 61a capable of emitting multicolor light as a plurality of (eight in this embodiment) light emitters.

  In this embodiment, a rotating accessory 61 is provided in the upper right part of the front of the center unit 40. As described above, in the pachinko machine 1, a game ball is launched from the upper left of the game area 12. In general, a player who plays a game with the pachinko machine 1 aims to win the game ball to the first start port 72 and the second start port 73 by causing the game ball to flow down to the left side of the center unit 40. Therefore, in this embodiment, the rotating accessory 61 is provided in the front upper right part of the center unit 40 corresponding to the front upper right part of the game area 12 that has the least influence on the game of the player.

  As shown in FIG. 15, the rotating unit 60 includes a rotating combination 61 provided at the tip of the rotating shaft (motor shaft 63 a) of the motor 63, a motor 63 that rotationally drives the rotating combination 61, The rotary shaft (motor shaft 63a) is built in, and is composed of a rotating member main body 62 provided with various substrates, and a mounting substrate 64 screwed to the rotating member main body 62. In addition, a rotating accessory 61 is attached to the tip of the motor shaft 63a, and a motor board 63a is built in the back side of the rotating accessory 61 and a relay board for relaying signals from the accessory control board 115 and the like. A built-in rotating accessory body 62 is located, and a motor 63 is located on the back side thereof. In addition, the mounting board 64 is screwed to the rotating accessory body 62, and a screw is inserted into a mounting hole 64 a formed in the mounting board 64 and screwed to the back side of the game board 4.

  The rotating combination 61 in the present embodiment has a rectangular parallelepiped shape (also called a rod shape) by a front plate 611 on the front, upper and lower side plates 612, left and right side plates 613, and a bottom plate 614 on the back (see FIG. 16B). ). Further, the height from the bottom plate 614 to the front plate 611 <the vertical length from the upper side plate 612 to the lower side plate 612 <the horizontal length from the left side plate 613 to the right side plate 613 increases in this order. It is formed as follows. In this embodiment, the rotating accessory 61 may be configured such that at least the lateral length from the left side plate 613 to the right side plate 613 is longer than the other sides, and from the bottom plate 614 to the front plate 611. And the vertical length from the upper side plate 612 to the lower side plate 612 may be the same, or one may be longer.

  In addition, the upper and lower side plates 612, the left and right side plates 613, and the bottom plate 614 on the back are integrally formed and open upward from the bottom plate 614. And it seals by mounting | wearing the front plate 611 from upper direction so that opening may be plugged up. In addition, inside the rotating accessory 61, eight LEDs 61a capable of emitting multicolor light, an IC (not shown) for controlling the light emission of the LED 61a, a capacitor (not shown) for storing power supplied to the LED 61a and the IC, and the like, etc. The board on which is mounted.

  In this embodiment, the upper part is formed substantially in parallel with the front plate 611 from the bottom plate 614 to the front plate 611, and is formed so as to protrude from the one of the side plates 612 and 613 toward the inner side of the rotary member 61. A plurality of holding portions 614a are provided. The holding portion 614a is formed to have a predetermined height (height in the direction of the front plate 611) from the bottom plate 614, and the above-described substrate is placed thereon. Further, by placing this substrate, the inner region of the rotating accessory 61 is divided into two regions, the front plate 611 side and the bottom plate 614 side. As will be described later, a capacitor, an IC, and the like are mounted on the back side of the substrate (on the bottom plate 614 side of the substrate), and the holding portion 614a is formed so as to be able to mount the capacitor and the IC. That is, the height from the bottom plate 614 may be as long as a capacitor, IC, or the like can be mounted.

  Although not shown, the front plate 611 has a holding portion at a position corresponding to the holding portion 614 a formed on the bottom plate 614 and the side plates 611 and 613. The holding portion 614a formed on the bottom plate 614 and the side plates 611 and 613 and the holding portion formed on the front plate 611 are formed so as to have an interval similar to the thickness of the substrate to be placed. And a board | substrate is inserted in the inside of the rotation accessory 61 in the state which is not mounting | wearing with the front board 611, and a board | substrate is mounted in the holding | maintenance part 614a. Then, by mounting the front plate 611, the substrate is sandwiched and fixed by the holding portion formed on the front plate and the holding portions 614 a formed on the bottom plate 614 and the side plates 611 and 613. Further, the rotating member 61 is assembled by screwing the bottom plate 614, the substrate, and the front plate 611 with screws from the bottom plate 614 side and sealing them. At this time, the substrate is in contact with the inner peripheral side surface of the rotating accessory 61 and is sandwiched between the holding portion 614 a formed on the bottom plate 614 and the side plates 611 and 613 and the holding portion formed on the front plate 611. As a result, the rotating combination 61 is firmly fixed inside the rotating combination 61 and rotates together with the rotating combination 61 when the rotating combination 61 is rotated.

  In addition, a plurality of vent holes 61 b are provided in the bottom plate 614 side and the bottom plate 614 of the upper and lower side plates 612 of the rotating accessory 61. By rotating the rotating combination 61, air flows from the vent 61 b and circulates the air inside the rotating combination 61. Note that the LEDs 61a, ICs, capacitors, and the like mounted on the board built in the rotating accessory 61 are soldered to the board. Further, the LED 61a, IC, capacitor, and the like generate heat when operating, and there is a possibility that the solder melts and peels off from the substrate or a contact failure occurs. Therefore, a ventilation hole 61b is formed, and when the rotating member 61 is rotated, the air inside the rotating member 61 is circulated to cool the LED 61a, the IC, the condenser, etc., and suppress the temperature rise. ing. In addition, by mounting a capacitor on a substrate built in the rotating member 61 and storing the capacitor, the LED 61a and the IC can be driven stably.

  16A is a side view of the rotating unit 60, and FIG. 16B is a cross-sectional view of the rotating accessory 61 cut along the XY plane in FIG. 16A.

  Although not shown in FIG. 16B, the substrate on which the LED 61a, IC, capacitor, and the like are mounted is the same as the area surrounded by the upper and lower side plates 612 and the left and right side plates 613 of the rotating accessory 61. The rotating member 61 is in contact with the inner peripheral side surface of the rotating member 61 and is attached in parallel to the front plate 611 of the rotating member 61. The LED 61a is mounted on the front surface of the substrate, and the IC and the capacitor are mounted on the back surface of the substrate. 16B, the motor shaft 63a of the motor 63 is provided at the center of the bottom plate 614 of the rotating accessory 61 (the intersection of the bottom plate 614 longitudinal direction center line and the bottom plate 614 short direction center line). Inserted, the center of the rotating combination 61 and the rotation axis of the rotating combination 61 coincide. In other words, the rotating accessory 61 in this embodiment has the same length on one end side in the longitudinal direction of the bottom plate 614 from the motor shaft 63a and the length on the other end side in the longitudinal direction of the bottom plate 614, and the motor shaft 63a. The length of the bottom plate 614 at one end in the short direction is the same as the length of the bottom plate 614 at the other end in the short direction.

  Further, in this embodiment, the LEDs 61a are mounted at equal intervals along the center line in the lateral direction of the substrate in the region on one end side of the left and right side plates 613 from the approximate center of the substrate (see FIG. 4). Further, an IC is mounted on the rear surface of the substrate in the region on the one end side where the LED 61a is mounted along the center line in the short side direction of the substrate, and in the region on the other end side where the LED is not mounted, A capacitor is mounted along the center line. Further, in this embodiment, the IC is installed at a position close to the longitudinal direction of the substrate from the rotating shaft of the rotating member 61 (center of the rotating member 61), and the capacitor is connected to the rotating shaft of the rotating member 61 (the rotating member 61). LED 61a and IC by installing each member along the center line in the lateral direction of the substrate and at a position distant from the center of the substrate) in the longitudinal direction of the substrate (position close to the end in the longitudinal direction of the substrate). Is configured so that the weight balance between the one end side on which the capacitor is mounted and the other end side on which the capacitor is mounted is kept even, and the center of gravity of the substrate is at the center of the substrate. Note that the center of the substrate coincides with the center of the rotating combination 61, and the center of gravity of the rotating combination 61 coincides with the center of gravity of the substrate. As described above, the motor shaft 63a is inserted in the center of the rotating combination 61, and the center of the rotating combination 61 and the rotation axis of the rotating combination 61 coincide with each other. (The center of gravity of the substrate built in the rotating combination 61) and the rotation axis of the rotating combination 61 coincide with each other.

  As described above, in this embodiment, the rotating combination 61 is formed so that the weight balance is uniform around the motor shaft 63a. Since they coincide, it is possible to prevent centrifugation and to reduce vibrations generated by centrifugation. In addition, the motor 63 can be rotated at a high speed, and the motor 63 can be rapidly rotated and stopped, thereby preventing the motor from stepping out.

  The rotating unit 60 configured as described above rotates the rotating object 61 at a high speed by driving the motor 63 at a high speed based on the drive signal from the accessory CPU 116 (in this embodiment, 1200 rotations per minute). ) At this time, the LED 61a is controlled to emit light with a predetermined light emission pattern (for example, a pattern such as a light emission time, a light emission position, a light emission color, and the like), thereby causing afterimages (also referred to as afterimages) of a plurality of types (for example, fireworks). Is displayed. Generally, a beautiful afterimage can be displayed by increasing the rotation speed of the motor 63. In this embodiment, the afterglow can be displayed by rotating the motor 63 at a rotation speed of 600 revolutions per minute. However, in order to display a more beautiful afterglow, it is 1200 per minute. The number of revolutions is necessary. In addition, you may comprise so that a still more beautiful shadow may be displayed by making the rotation speed of the motor 63 into 1200 rotations or more per minute.

  Thus, in this embodiment, since the afterglow of a plurality of types is displayed by rotating the motor 63 at a high speed and controlling the LED 61a to emit light with a predetermined light emission pattern, a plurality of types of modes are used for the afterglow. The number of LEDs 61a to be mounted can be reduced compared to the case where no is displayed, and there is an advantage that the manufacturing cost of the pachinko machine 1 can be reduced. However, in order to display an afterimage, the motor 63 must be rotated at a high speed. By rotating the motor 63 at a high speed, the occurrence of vibration and the degree (magnitude) of the vibration increase, and the game area 12 is displayed. There is a risk of affecting the game balls that flow down and the game balls that roll on the stage 50. The pachinko machine 1 used in the present embodiment is a method of attaching each member constituting the center unit 40 to the game board 4 so that the vibration generated by driving the motor 63 does not affect the rolling of the game ball. Is devised. Hereinafter, a method of attaching each member constituting the center unit 40 to the game board 4 will be described.

  FIG. 17 is an exploded perspective view of the center unit 40 as viewed from the front side of the game board 4, and FIG. 18 is an exploded perspective view of the center unit 40 as viewed from the back side of the game board 4.

The stage unit 50a and the ball guide member 65 have a predetermined width from the opening of the mounting unit 81 to the back side in the depth direction, and the stage unit 50a and the ball guide member are disposed on the back side of the opening of the mounting unit 81. 65, a space in a predetermined range surrounded by the upper decorative body 87 and the image display device 42.

  In addition, as described above, the rotation unit 60 includes the rotating combination 61, the motor 63, the rotating combination main body 62, and the mounting substrate 64. Further, a boss hole 62 a is formed in the rotating accessory body 62 in correspondence with the boss 81 b formed in the attachment unit 81. Then, the rotation unit 60 is positioned by inserting the boss 81 b of the attachment unit 81 into the boss hole 62 a of the rotary accessory body 62. At this time, the rotating combination body 62 plays a role of positioning the rotating unit 60, but the rotating unit 60 itself is not attached to the rotating combination body 62. In this embodiment, the rotation unit 60 is fixed to the game board 4 by inserting screws into the attachment holes 64a formed in the attachment board 64 of the rotation unit 60 and screwing them directly to the back surface of the game board 4 ( (See FIG. 19 and FIG. 20). Further, when the rotary unit 60 is fixed to the game board 4, the motor shaft 63 a of the motor 63 is attached so as to be substantially perpendicular to the back surface of the game board 4.

  In order to assemble the rear unit 83, first, the rotating accessory 61 of the rotating unit 60 is inserted from the opening of the mounting unit 81 and protrudes forward from the upper right part of the opening of the mounting unit 81. The boss 81 b formed on the back side of the 81 is inserted into the boss hole 62 a of the rotary accessory body 62. In this state, the boss 81c of the mounting unit 81 is inserted into the boss hole 86a of the mounting board 86 from the back side of the mounting unit 81, and a screw is inserted into a part of the boss hole 86a from the back side of the mounting board 86. The rear unit 83 is assembled by screwing with the unit 81. In addition, the upper right portion of the mounting board 86 of the back decorative body 82 is scraped off, and the rotation unit 60 can be disposed on the upper right portion of the mounting unit 81. That is, a space for inserting the rotation unit 60 is formed by scraping the upper right portion of the mounting substrate 86, and the rotation unit 60 can be provided as a constituent member in the rear unit 83.

  In the rear unit 83 assembled in this way, since the rotary unit 60 is not screwed to the mounting unit 81, the rotary unit 60 may be detached. In this embodiment, an anti-sliding member 84 is provided on the rear side of the upper right portion of the mounting substrate 86 that has been cut away. The slip-off preventing member 84 is located on the back portion of the rotating accessory main body 62 of the rotating unit 60 when the rear unit 83 is assembled, and prevents the rotating unit 60 from slipping by contacting the rotating accessory main body 62. It is. When the rotation unit 60 and the attachment unit 81 are screwed to the game board 4, the slip-preventing member 84 and the rotating accessory body 62 are not in contact with each other.

  The front decorative body 80 attached from the front side of the game board 4 is formed in a shape in which the portion of the latter half (connecting insertion portion) facing the game board 4 is completely inserted into the through hole 4a when viewed in the front-rear direction. The front decorative body 80 is attached to the game board 4 in a state where a half of the front decorative body 80 is fitted in the through hole 4a. The rear half of the front decorative body 80 has a thickness as viewed in the front-rear direction that is almost the same as the thickness of the game board 4. For this reason, when the front decorative body 80 is attached to the game board 4, the subsequent half of the body is flush with the back of the game board 4 (so-called flush state).

  Further, the front decorative body 80 is formed with a boss 80b that protrudes rearward from the rear half portion (insertion connecting portion). Two bosses 80b are formed at a lower position of the front decorative body 80, and both of them protrude further rearward from the back of the game board 4 when inserted from the front side of the game board 4 through the through holes 4a. When the front decorative body 80 and the rear unit 83 are attached to the game board 4 from the front and rear, the boss 80b reaches the rear unit 83 through the through hole 4a and is attached by being inserted into the boss hole 81a of the attachment unit 81. The unit 81 is positioned mutually. Thus, in this embodiment, the front decorative body 80 attached from the front side of the game board 4 and the attachment unit 81 attached from the back side of the game board 4 are configured to be positioned relative to each other. The mounting to the game board 4 becomes easy.

  On the other hand, in a state where the front decorative body 80 is attached to the game board 4, the front half part projects to the front side of the game board 4. The thickness of the front half portion is set to be substantially the same as that of the guide rail 11 or the like, for example. For this reason, when the front decorative body 80 is attached to the game board 4, the front half of the front decorative body 80 projects forward from the board surface within the game area 12, thereby guiding and guiding the flow of the game ball.

  The center unit 40 is assembled by screwing the front decoration body 80 configured as described above and the rear unit 83 to the game board 4 with screws. Note that the opening of the front decorative body 80 and the opening of the mounting unit 81 are formed to have substantially the same size, and the front decorative body 80 and the rear unit 83 are positioned relative to each other so that the center unit 40 is positioned. Is assembled, the opening of the front decorative body 80 and the opening of the mounting unit 81 are matched. As described above, the ball guiding member 65, the stage unit 50 a, the upper decorative body 87, and the display unit 85 attached from the back side of the opening of the mounting board 86 are provided on the back side of the opening of the mounting unit 81. Since the image display device 42 is located, in the center unit 40, the ball guide member 65, the stage unit 50 a, the upper decorative body 87, and the display unit 85 attached from the back side of the opening of the attachment substrate 86 from the front side. The image display device 42 is visible.

  As described above, the stage unit 50 a is partly formed flat and attached so as to be flush with the flat front surface of the attachment unit 81, and comes into contact with the lower end portion of the front decorative body 80. 50 is formed. In addition, the upper decorative body 87 enhances the decorativeness around the image display device 42 and is formed of an opaque resin and functions as a blindfold that makes the back portion of the pachinko machine 1 invisible. Further, by attaching the front decorative body 80 and the rear unit 83 to the game board 4, the rotating accessory 61 passes through the upper right part of the opening of the front decorative body 80 and protrudes forward of the game board 4, and directly from the player. It will be in a visible state. That is, the rotating accessory 61 is exposed to the front side of the game board 4 without being covered by the front decorative body 80, and is in a state that can be directly recognized by the player.

  The rotating unit 60 is fixed to the game board 4 by inserting a screw into a mounting hole 64 a formed in the mounting board 64 and screwing it directly to the back of the game board 4. Further, in this embodiment, the mounting board 64 is divided into an upper part and a left part when viewed from the back side of the game board 4, and three holes are provided as attachment holes 64 a in the part contacting the back side of the game board 4. Is formed. When screwing onto the game board 4, two holes are screwed into the upper and left sides as viewed from the back side of the game board 4 using one of the holes. When the rotary unit 60 is replaced due to a problem or the like, a hole in which a screw is screwed is formed in the back of the game board 4 before, and it is difficult to fix the rotary unit 60 again. Therefore, it is possible to screw the rotary unit 60 to the game board 4 by screwing with screws using the other holes of the mounting holes 64a. That is, the mounting hole 64a includes a spare hole.

  FIG. 21 is a cross-sectional view of the game board 4 cut along the ST plane, and FIG. 22 is an enlarged view of FIG.

  As shown in FIG. 21B, in this embodiment, the stage 50 further has a predetermined width from the back of the game board 4 in the depth direction (pachinko machine 1 depth direction). The image display device 42 is located at the end position. That is, the image display device 42 is provided at a position deeper on the back side from the game board 4. Further, the rotation unit 60 is attached so that the motor shaft 63a is substantially perpendicular to the game board 4, and a rotating accessory 61 is provided so as to protrude forward from the surface of the game board 4. Further, the rotating accessory 61 is disposed in the upper right part of the center unit 40.

  As described above, since the rotating combination 61 is set apart from the image display device 42 by a predetermined distance (distance that sandwiches the stage 50 provided in the center unit 40), the position where the display overlaps is the position of the player's line of sight. Can be different.

  For example, in a display area where the display of the rotary unit 60 and the display of the image display device 42 overlap from any position, information related to the winning can be visually recognized only when the player views from a specific position. In the center unit 40 having a depth, for example, an unprecedented presentation can be performed by having a predetermined distance between the display devices, and the player changes the viewing position to see the display. Further gameability can be provided to the player.

  Further, a part of the rotating unit 60 is in contact with the mounting unit 81 (is loosely fitted), but the other part is not in contact with the mounting unit 81 and the back surface decoration body 82. Specifically, as shown in FIG. 22, the boss 81 b formed on the mounting unit 81 is inserted into the boss hole 62 a formed on the rotating accessory body 62 of the rotating unit 60, thereby causing the mounting unit 81 and the rotating unit 60 to move. However, the other portions are not in contact with the rotating unit 60 in a state of being displaced in the vertical and horizontal directions and the front and rear directions in FIG.

  As described above, the game ball that is inserted into the guide passage 58 provided in the stage 50 is likely to win the first starting port 72 and the second starting port 73. The vibration propagates to each member (circular guide portion 54, upper rail 52, lower rail 53, etc.) provided above, affecting the rolling of the game ball trying to fit into the guide passage 58, There is a possibility that the winning to the first starting port 72 and the second starting port 73 is affected, which is disadvantageous to the player.

  In the present embodiment, the rotary unit 60 is directly screwed to the game board 4 and is not screwed to the back decoration body 82 to which the stage 50 is screwed and the mounting unit 81 to which the back decoration body 82 is screwed. 60, it is possible to reduce propagation of vibrations generated by driving the motor 63 to the attachment unit 81, the back decoration body 82, and the front decoration body 80. As a result, it can comprise so that the winning to the 1st starting port 72 and the 2nd starting port 73 may not be affected.

  Note that the attachment unit 81 and the back decoration 82 attached from the back side of the game board 4 are made of a synthetic resin or the like and become light. Therefore, when the rotary unit 60 is screwed and driven to the attachment unit 81 and the back surface decoration body 82, vibration generated by driving the rotary unit 60 is easily propagated. Further, the back decoration body 82 constitutes a part of the stage 50 and includes a stage unit 50 a related to winning in the first start port 72 and the second start port 73, so that vibration propagates to the back decoration body 82. As a result, vibration is also propagated to the stage 50, which may be disadvantageous to the player.

  On the other hand, in general, the game board 4 is heavy because the board itself is heavy, and various boards such as the main board group and the peripheral board group described above are provided and various apparatuses such as the image display device 42 are attached. Become. Thus, since the game board 4 is heavy, when the rotation unit 60 is attached to the game board 4 and driven, vibration generated by driving the rotation unit 60 is difficult to propagate to the game board 4. Furthermore, it is difficult for vibration generated by the rotating unit 60 to propagate to the mounting unit 81, the back decoration body 82, and the front decoration body 80 via the game board 4.

  In this embodiment, the mounting unit 81 and the rotating unit 60 are brought into contact with each other by inserting the boss 81b formed in the mounting unit 81 into the boss hole 62a formed in the rotating accessory body 62 of the rotating unit 60. Although it is in a state, since the rotation unit 60 is screwed to the game board 4 and vibration is suppressed, vibration does not propagate from the boss 81 b to the mounting unit 81. As described above, in this embodiment, the rotation unit 60 is screwed directly to the game board 4 and is not screwed to the mounting unit 81 and the back decoration body 82, so that vibration is transmitted to the mounting unit 81 and the back decoration body 82. It can be reduced.

  In this embodiment, the boss 81b formed in the mounting unit 81 is inserted into the boss hole 62a formed in the rotating accessory body 62 of the rotating unit 60, whereby a part of the mounting unit 81 and the rotating unit 60 is obtained. However, the mounting unit 81 and the rotating unit 60 may be configured not to contact each other by configuring the boss hole 62a and the boss 81b so as not to be provided. In this case, the rotary unit 60 is not positioned, but a normal mounting position can be obtained by providing positioning marks (for example, holes, marks, etc.) corresponding to the mounting holes 64a on the back of the game board 4. You may comprise so that the rotation unit 60 can be attached to.

  In this embodiment, the method of attaching the game board 4 to the pachinko machine 1 is devised in order to suppress the vibration generated by driving the rotary unit 60. This will be described below. FIG. 23 is a front view of the pachinko machine 1 with the game board 4 attached and the front frame 5 removed. FIG. 24 is an enlarged view of the mounting mechanism of the game board 4.

  As shown in FIG. 23, two engagement protrusions 33 formed on the upper and lower left sides of the game board mounting frame 9 and two engagement holes formed on the upper and lower left sides of the board surface (front surface) of the game board 4. 34, the left side of the game board 4 is locked, two engagement recesses 36 formed on the upper and lower sides of the right side of the game board mounting frame 9, and two on the upper and lower sides of the right side of the board surface of the game board 4. The right side portion of the game board 4 is engaged by the engagement hook 35.

  The engagement hook 35 detachably locks the game board 4 and the game board mounting frame 9 at two positions, a LOCK position where the engagement recess 36 can be locked and a UNLOCK position where the engagement hook 35 is retracted. . As shown in FIG. 24, the engagement hook 35 is formed in a laterally long shape with a synthetic resin material, and can be engaged with and disengaged from the engagement recess 36 of the game board mounting frame 9 at one end portion in the longitudinal direction. A locking portion 35a that engages and fixes the game board 4 is integrally formed. Further, the engagement hook 35 has a shaft portion 35d projecting from the upper and lower portions, and a rail (not shown) that sandwiches the shaft portion 35d is formed in the storage recess 39, and the shaft portion 35d is connected to the storage recess 39. The engagement hook 35 can be moved in the left-right direction in the figure by sliding in the rail. Thus, the engagement hook 35 is rotated so that the locking portion 35a is positioned in the front direction of the pachinko machine 1 with the shaft portion 35d as an axis, and is fitted into the storage recess 39.

  Further, a check portion 35e is provided at the other end of the engagement hook 35 where the engagement portion 35a in the longitudinal direction is not provided to prevent the engagement hook 35 restrained by the storage recess 39 from coming off. Yes. The check portion 35e is engaged with a check protrusion (not shown) provided in the storage recess 39, and is prevented from rotating so that the locking portion 35a is positioned in the back direction of the pachinko machine 1 with the shaft portion 35d as an axis. In addition, the engagement hook 35 is securely restrained in the storage recess 39. In addition, by pressing the check portion 35e in the right direction in the figure, the engagement between the check portion 35e and the check protrusion is released, and the engagement hook 35 can be moved.

  Further, on the right side of the check portion 35e in the figure, a handle portion 35b is integrally formed to operate the LOCK and UNLOCK by moving the engagement hook 35 forward and backward. The handle portion 35b is formed in a substantially square ring shape. Thus, by operating the handle portion 35b and moving the engagement hook 35 to the LOCK position, the locking portion 35a protrudes to the outside of the game board 4 to be locked with the engagement recess 36, and the handle portion 35b. To move the engaging hook 35 to the UNLOCK position, the engaging portion 35a is retracted without projecting to the outside of the game board 4 and cannot be engaged with the engaging recess 36.

  In this embodiment, the storage recess 39 and the engagement hook 35 provided in the game board 4 are restricted from advancing and retracting the engagement hook 35 at two positions, a LOCK position and an UNLOCK position. That is, the engagement hook 35 is located above and below the engagement recess 35 so as to be engageable with the first restriction recess 39a and the second restriction recess 39b that are located in the upper and lower portions of the storage recess 39 and are recessed in the game board 4. A projecting pin-shaped restricting convex portion 35c is provided. Then, the engagement hook 35 is moved to a position where the first restriction concave portion 39a and the restriction convex portion 35c correspond to press the handle portion 35b to engage the check portion 35e with the check protrusion. The restriction convex part 35c is fitted and engaged with the restriction concave part 39a, and the engagement hook 35 is restrained to the LOCK position to restrict the movement in the horizontal direction in the figure. On the other hand, the engagement hook 35 is moved to a position where the second restriction concave portion 39b and the restriction convex portion 35c correspond to press the handle portion 35b to engage the check portion 35e with the check protrusion. The restriction convex part 35c is fitted and engaged with the restriction concave part 39b, and the engagement hook 35 is restrained at the UNLOCK position to restrict the movement in the horizontal direction in the figure.

  The handle 35b of the engagement hook 35 is pressed, and the engagement hook 35 is rotated so that the locking portion 35a is positioned in the forward direction of the pachinko machine 1 with the shaft 35d as an axis. The inserted locking portion 35a presses the engagement recess 36 in the front side of the figure. As a result, the game board 4 is pressed into the game board mounting frame 9 in the depth direction of the pachinko machine 1 and is securely fixed to the game board mounting frame 9. That is, after the locking hole 34 formed on the left side portion of the game board 4 is brought into contact with the engagement protrusion 33 formed on the left side portion of the game board mounting frame 9, the left side portion of the game board 4 is rotated on the rotation axis. And the engagement board 35 is engaged with the engagement protrusion 33 by engaging the game board 4 with the game board mounting frame 9 and engaging hooks 35 formed on the right side of the game board 4. The regulation projection 35c is fitted into the first regulation recess 39a from the state where the engagement hook 35 is restrained to the UNLOCK position by operating and fitting the regulation projection 35c into the second regulation recess 39b. By engaging, the engagement hook 35 moves to a state where it is constrained to the LOCK position, and the engagement portion 35a protrudes outside the game board 4 and engages with the engagement recess 36 formed in the game board mounting frame 9. And by pressing the game board 4 in the back direction of the pachinko machine 1 Trick plate 4 is locked and fixed on the game board mounting frame 9.

  Further, a locking hook 38 is formed in the lower left portion of the game board 4, and an urging lock portion 37 corresponding to the locking hook 38 is provided in the lower left portion of the game board mounting frame 9. When the game board 4 is mounted on the game board mounting frame 9, the urging lock portion 37 urges the locking hook 38 downward to lock it. The urging lock portion 37 urges the locking hook 38 downward so that the gaming board 4 can be locked while applying a downward urging force. As a result, the game board 4 comes into close contact with the lower edge of the game board mounting frame 9 and is pressed and fixed downward.

  As described above, in this embodiment, the left side portion of the game board 4 is engaged by the engagement protrusion 33 and the engagement hole 34, and the engagement portion 35a is inserted and engaged in the engagement recess 36. At the same time, the game board 4 is firmly fixed and locked to the game board mounting frame 9 by pressing the game board 4 in the depth direction of the pachinko machine 1. In this embodiment, the game board 4 can be more firmly fixed to the game board mounting frame 9 by pressing and fixing the game board 4 downward by the locking hook 38 and the biasing lock portion 37. Further, since the game board mounting frame 9 is integrally formed with the main body frame 3, the fact that the game board 4 is fixed to the game board mounting frame 9 means that the game board 4 is fixed to the pachinko machine 1. means. Further, when the pachinko machine 1 is installed in a game arcade, the outer frame 2 is attached to a gaming island where a plurality of gaming machines are arranged by nailing or the like so that the pachinko machine 1 does not vibrate. That is, the propagation of the vibration generated by the motor 63 of the rotating accessory 61 is caused by the propagation suppressing means constituted by any one of the game board 4, the game board 4 and the pachinko machine 1, and the game board 4, the pachinko machine 1 and the game island. It is suppressed, the game board 4 can be securely fixed and the occurrence of vibration can be suppressed, and the rolling of the game ball flowing down the surface of the game board 4 is not affected.

  Furthermore, in this embodiment, the rotating tool 61 is attached so as to be located on the upper right side of the game area 12, and the engagement hook 35 is located in the vicinity thereof, and as described above, the engagement hook 35 and the engagement concave portion are located. 36, the game board 4 is firmly fixed. Therefore, the vibration generated by the motor 63 is suppressed by the engagement hook 35 and the engagement recess 36 as the fixing members located in the vicinity, and the propagation of the vibration generated by the motor 63 is suppressed. Note that the vibration generated by the motor 63 is suppressed and the propagation of the vibration generated by the motor 63 is suppressed by attaching the rotating member 61 in the vicinity of the locking hook and the biasing lock portion 37 as a fixing member. You may comprise. On the other hand, when the rotating accessory 61 is mounted on the left side of the game area 12, the engagement hook 35 and the engagement recess 36 as the fixing members are not positioned in the vicinity, and thus generated by the motor 63. The effect of suppressing vibration is reduced and propagation of vibration generated by the motor 63 is not suppressed. That is, the engagement hook 35 and the engagement recess 36 are engaged with no play, but the engagement protrusion 33 and the lock hole 34 are locked so as to have some play. Suppressive effect is weak.

  Further, when the rotating tool 61 is directly screwed to the game board 4 fixed to the pachinko machine 1 in this way, the vibration from the rotating unit 60 hardly propagates to the game board 4 and the rotating tool 61 is rotated. In this case, vibrations generated in this case are suppressed and the rolling of the game ball flowing down the game area 12 is not affected. Further, by suppressing the vibration, the propagation of vibration from the game board 4 to the stage 50 is reduced, and the rolling of the game ball on the stage 50 is not affected. As a result, winning in the first starting port 72 and the second starting port 73 is not affected. Further, by suppressing the vibration of the rotating unit 60, it is possible to prevent the vibration from propagating to the mounting unit 81 from the portion where the mounting unit 81 and the rotating unit 60 are in contact.

  Note that the rotating unit 60 in this embodiment rotationally drives the rotating combination 61 substantially horizontally with the game board 4 so that the rotation range of the rotating combination 61 overlaps a part of the image display device 42 in the front-rear direction. Specifically, the rotating combination 61 is rotationally driven in front of the image display device 42, so that about one-quarter of the length of the rotating combination 61 in the longitudinal direction is driven by the rotation. Pass through a position that covers a part of. With this configuration, it becomes easy for a player who is paying attention to the image display device 42 to recognize that the rotating accessory 61 has been driven, and further, an effect and rotation executed by the image display device 42. It becomes possible to execute the drive driving control of the accessory 61 more closely synchronized. In addition, it is possible to give the impression that the rotating combination 61 is raised in front of the image display device 42 and to provide a three-dimensional effect in the front-rear direction of the pachinko machine 1. Note that the area in which the image display device 42 is covered with the rotating accessory 61 is desirably 25% or less of the entire area of the image display device 42.

  Further, when the motor 63 is not driven, it stops at a position that does not cover a part of the image display device 42 as an initial position (in this embodiment, a stop position of the rotating accessory 61 shown in FIG. 21). Even when the motor 63 is driven to rotate the rotating member 61, when the motor 63 is stopped, the rotating member 61 is stopped so as to be in the initial position. With this configuration, it is possible to prevent a part of the image display device 42 located on the back side of the rotating combination 61 from being invisible in a state where the rotating combination 61 is not rotated.

  In this embodiment, the accessory ROM 117 mounted on the accessory control board 115 stores a plurality of light emission patterns in which the rotation mode of the rotation tool 61 and the light emission mode of the LED 61a are described. When the special symbol display 41 starts the variable display of the special symbol (when the image display device 42 starts the variable symbol display), the signal is received from the sub-integrated board 111 via the lamp relay board 119. One of a plurality of types of light emission patterns stored in the accessory ROM 117 is selected based on the signal, and a drive signal is output to the motor 63 and the LED 61a based on the selected light emission pattern. In other words, in synchronization with the special symbol variation display on the special symbol display 41 and the decorative symbol variation display on the image display device 42, the rotating combination 61 is driven to rotate in a predetermined light emission pattern, and the rotation combination 61 is placed inside the rotating combination 61. The LED 61a provided is controlled to emit light with a predetermined emission pattern. By rotating and driving the rotating combination 61 with a predetermined light emission pattern and controlling the light emission of the LED 61a provided inside the rotating combination 61 with a predetermined light emission pattern, an afterglow of a predetermined mode is generated in front of the image display device 42. Is displayed. FIG. 25 shows an example of the afterglow displayed by the rotating combination 61.

  As shown in FIGS. 25A to 25C, the fireworks shown in FIG. 25A are controlled by controlling the light emission of the LED 61a with a predetermined light emission pattern when the rotary member 61 is rotationally driven. A cloud shown in B), a lightning shown in FIG. 25C, and the like are displayed in front of the image display device 42 so as to overlap a part of the image display device 42. Therefore, it becomes easier for a player who is paying attention to the image display device 42 to recognize that the rotating combination 61 is driven, and it is possible to pay attention to the afterglow displayed on the rotating combination 61. Become. Further, since the afterimages of a plurality of types are displayed so as to protrude forward from the image displayed on the image display device 42, a further impact can be given to the player.

  In FIG. 25A to FIG. 25C, the image display device 42 located behind the afterglow displayed on the rotating combination 61 is in a transparent state. That is, in this embodiment, the rotating combination 61 is rotationally driven so as to cover a part of the image display device 42 in front of the image display device 42. However, as described above, the rotating combination 61 is driven at high speed by the motor 63. Since the rotation (the number of rotations of 1200 rotations per minute) is reduced, the time required for the rotating agent 61 to pass so as to cover a part of the image display device 42 is shortened. Can be seen through. In order to make the image display device 42 on the back side transparent when the rotary combination 61 is driven to rotate, it is desirable that the rotation speed of the rotary combination 61 be 700 rotations or more per minute.

  Moreover, in this embodiment, the afterglow is displayed by the rectangular parallelepiped rotating accessory 61 in which the LED 61a is mounted only on one end side from the longitudinal center of the surface. The LED 61a may be mounted from one end in the longitudinal direction to the other end in the longitudinal direction on the surface of the rotating accessory 61. In this case, the rotational speed of the motor is set to the rotational speed (the rotational speed of this embodiment ( Although it is possible to display a beautiful afterglow (for example, 600 revolutions per minute) even if it is slower than 1200 revolutions per minute, the brightness of the afterglows displayed by increasing the number of LEDs 61a (Luminance at a predetermined position) increases, causing a problem that it becomes difficult to see the display of the image display device 42 located on the back side of the afterglow. Further, it is possible to reduce the brightness of the afterimage by further reducing the rotation speed of the rotating agent 61, but by reducing the rotation speed of the rotating agent 61, It takes a long time to cover a part of the image display device 42, causing a problem that a part of the image display device 42 cannot be visually recognized.

  Further, as described above, in this embodiment, the center of the rotating combination 61 is rotated with the center of the rotating combination 61 as the rotation axis by matching the center of the rotating combination 61 with the rotation axis of the rotating combination 61. However, the motor shaft is inserted substantially perpendicularly to the game board 4 at the longitudinal end portion of the rotating accessory and rotated around the longitudinal end portion of the rotating accessory, and the LED is controlled to emit light. It is also possible to display shadows. However, since the motor shaft and the center of gravity do not coincide with each other, the load applied to the motor increases, making it difficult to rotate the motor at a high speed and to make a sudden rotation and a sudden stop. Moreover, centrifugation occurs and vibration increases. As described above, since the motor cannot be rotated at a high speed, a beautiful afterimage cannot be displayed. These problems can be solved by reducing the weight of the rotating tool, but by reducing the weight of the rotating tool, the number and types of LEDs that can be mounted (single color light emission) are limited and various. I can't perform any staging.

  In addition, a motor shaft is inserted perpendicularly to the game board 4 at the longitudinal end portion of the rotating combination, reciprocatingly driven around the longitudinal end portion of the rotating combination, and the afterglow is displayed by controlling the light emission of the LED. (For example, a pendulum type machine such as a metronome with an LED attached) is possible, but since it must be stopped once when it is driven from one state to the other, the afterglow in the part where it has stopped Brightness (luminance at a predetermined position) increases. Further, since the rapid rotation and the sudden stop are repeatedly executed, it is difficult to rotate the motor at a high speed, and the load on the motor increases. Moreover, centrifugation occurs and vibration increases. As described above, since the motor cannot be rotated at a high speed, a beautiful afterimage cannot be displayed. These problems can be solved by reducing the weight of the rotating tool, but by reducing the weight of the rotating tool, the number and types of LEDs that can be mounted (single color light emission) are limited and various. I can't perform any staging.

  In addition, a motor shaft provided substantially horizontally with the game board 4 is inserted into the center of the drum, reel, etc., and rotated around the center of the drum, reel, etc., and provided on the surface of the drum, reel, etc. Although the afterglow can be displayed by controlling the light emission of the LED, only a part of the drum and the reel can be visually recognized, and the afterglow cannot be displayed in the entire rotating area. Furthermore, when the pachinko machine 1 is installed in a state where a part of the drum, the reel, etc. enters the back part of the game board 4 and the pachinko machine 1 is attached to the game island, there is a restriction on the area of the back part of the game board 4, It was difficult to increase the size of reels and the like. In other words, when the pachinko machine 1 is attached to the amusement island, the area behind the pachinko machine 1 can be used only in an area where the pachinko machines 1 that are back to back do not touch each other. is there.

  Further, when a drum, a reel, or the like is installed in front of the image display device 42 so that a part of the image display device 42 is covered, a part of the image display device 42 is always covered by the drum and the reel. For this reason, the region covered by the drum and the reel becomes invisible. In the present embodiment, the motor shaft 63a of the motor 63 is provided substantially perpendicularly to the surface of the game board 4, and the rotating tool 61 is rotationally driven substantially horizontally with the game board 4 using the motor shaft 63a as a rotation axis. The entire rotating area of the rotating combination 61 can be visually recognized, and the afterglow can be displayed in the entire rotating area of the rotating combination 61. In addition, since the size of the rotating combination 61 is not related to the area of the back of the game board 4, it is easy to increase the size of the rotating combination 61.

  In addition, the lamp | ramp used in this embodiment is an example of a light-emitting body, and is not limited to them. That is, an apparatus configured using LEDs in the present embodiment may be configured using a lamp, or may be configured using another light emitter.

  Further, a part of the front plate 611 located in front of the LED 61a provided inside the rotating accessory 61 may be made semi-transparent so that each light emission of the LED 61a is not conspicuous. That is, in this embodiment, a plurality of types of modes are displayed at the points (dots) of light emitted by the individual LEDs 61a, but by directly translating a part of the front plate 611 located in front of the LEDs 61a, the LEDs 61a directly. Is not visible, and the light emitted from each LED 61a interferes with the translucent portion of the front plate 611 and is displayed evenly on the entire surface, thereby displaying a smooth mode.

  In this embodiment, the motor 63 and the LED 61a are driven based on the signal received from the sub-integrated board 111 via the lamp relay board 119. However, the timing for rotating the rotating member 61 is not limited to this. For example, after the power supply to the pachinko machine 1 is started, the motor 63 is continuously driven to rotate the rotary member 61, and the drive of the motor 63 is stopped based on the stop of the power supply. Thus, the rotating accessory 61 may be stopped. It should be noted that the vibration is greatest when the rotating combination 61 is rotated and when the rotation of the rotating combination 61 is stopped. Therefore, while the electric power is being supplied to the pachinko machine 1, the generation of vibration is suppressed by continuously rotating the rotating accessory 61 so that the game ball rolling on the stage 50 rolls. And the rolling of the game ball flowing down the game area 12 is not affected.

  In addition, the rotating accessory 61 in the present embodiment is formed by a rod-shaped member, but the shape thereof is not limited as long as it is rotationally driven substantially horizontally with respect to at least the front surface of the game board 4. For example, it may have a shape like a fan blade.

  In the present embodiment, eight LEDs 61 a are mounted on the rotating combination 61, but a rotation axis is inserted in the center of the rotation combination 61, and the rotation axis of the rotation combination 61 and the center of gravity of the rotation combination 61. The number of LEDs to be mounted is not limited. In addition, when the rotation axis of the rotating accessory 61 and the center of gravity of the rotating accessory 61 do not coincide with each other, a screw or the like is screwed into a predetermined position on the back side of the rotating accessory 61 (outside the bottom plate 614). It may be adjusted to keep the weight balance even.

  In addition, you may comprise so that multiple types of production can be performed by the change of the rotation speed of the rotation accessory 61, for example, the rotation speed of 600 rotations per minute, the rotation speed of 1200 rotations per minute, and 1 minute The rotary unit 60 is configured to be capable of being driven to rotate at a rotation speed of 1800 rpm, and when the special symbol display 41 starts to display the special symbol variation display (the image display device 42 starts to display the decorative symbol variation display). The ratio of driving the rotating combination 61 at a high rotational speed when it is determined to be a big hit, and the ratio of driving the rotating combination 61 at a low rotational speed when it is determined to be out of position. By configuring so as to increase, the expectation of jackpot (ratio of jackpot) may be increased when the rotating accessory 61 is rotationally driven at a high rotation speed.

  Further, when the rotating unit 60 is configured to be capable of rotating the rotating accessory 61 in both the clockwise and counterclockwise directions, and the special symbol display 41 starts to display the variation of the special symbol (the image display device 42). (When starting display of decorative symbols on the display), the ratio of driving in one direction of rotation (for example, counterclockwise) is increased when it is determined to be a big hit, and the other is determined when it is determined to be off The ratio of driving in the rotational direction (for example, clockwise) is increased so that the big hit expectation degree is increased when the rotational drive is performed in one rotational direction (for example, counterclockwise). Also good.

  As described above, according to the configuration of the present embodiment, the game ball discharged from the circular guide portion 54 through the guide passage 58 to the game area 12 collides with the game ball jumped up from the game area 12 onto the stage 50. Therefore, the discharge direction of the game ball discharged from the guide passage 58 (release port 51) does not change, and as a result, the game ball is discharged from the ball rolling surface (the guide passage 58 via the circular guide portion 54). The player's expectation for (emissions from) is not impaired.

  In general, in the case where the frequency (start winning rate) of the start winning (the winning of game balls to the first starting opening 72 and the second starting opening 73) is suppressed on the game hall side, the warp passage (main In the embodiment, the guidance of the game ball at the ball guide member 65) is suppressed, in other words, the nail so that the game ball does not easily enter the warp inlet (in this embodiment, the swing path member 43 and the ball path member 49). By adjusting, the frequency of starting prizes is suppressed, but when such nail adjustment is performed, most of the game balls that roll on the ball rolling surface are played by collision with obstacle nails. It becomes a game ball that jumps up from the area onto the ball rolling surface. However, the conventional general ball rolling surface is formed in a continuous and continuous stepped shape. For this reason, the game ball jumped up from the game area is rolled only on the lowermost ball rolling surface adjacent to the game area, and even if it is placed on the ball rolling surface, it is immediately discharged to the game area. The period during which game balls exist on the rolling surface was shortened. On the other hand, according to the configuration of the present embodiment, the ball rolling surface is configured to overlap two upper and lower stages, thereby widening the depth width of the stage 50 (stage unit 50a) as the lower ball rolling surface. The period during which the game ball exists on the ball rolling surface can be lengthened, and as a result, the interest in the flow of the game ball on the ball rolling surface is not reduced.

  Further, in the case where the frequency of start winning (start winning rate) is suppressed on the game hall side, the momentum of the game ball in the warp passage (in this embodiment, the ball guide member 65) is suppressed, thereby suppressing the momentum on the stage 50. Although the rolling width of the game ball is narrowed to prevent the game ball from being inserted into the guide passage 58, the start winning frequency may be suppressed. In this embodiment, the game ball is provided on the stage 50. The rolling width of the game ball in the circular guiding portion 54 is due to the momentum applied by the upper rail 52 and the lower rail 53, respectively, and the swing passage member 43 and the front decorative body 43 provided at the upper left portion of the front decorative body. Even if the initial velocity of the game ball in the ball passage member 49 provided in the upper right part of the ball is slow, the movement width is not narrowed by the influence, so the expectation for the start winning prize is not lowered, and the ball rolling Game ball on the surface It does not reduce the interest in the sphere flow.

  The configuration of the ball discharge passage according to the present invention is not limited to the guide passage 58 described in the embodiment. Hereinafter, modified examples of the ball discharge passage will be described. However, since other configurations are the same as those in the above-described embodiment, the description thereof is omitted for the sake of convenience. The ball discharge passage of the modified example is a structure of a guide passage (not shown) extending in communication with the wall portion a54 and the groove portion 54b at the front end portion (the game area 12 side) of the circular guide portion 54. The front end portion (downstream end portion) of the passage serves as a ball discharge portion that discharges the game ball to the game area 12. Then, when the game ball flows into the ball passage by the ball flow on the circular guide portion 54, the game ball is discharged directly from the position above the stage 50 to the game area 12. For this reason, even when the game ball jumps up on the stage 50 due to the collision with the obstacle nail, the game ball discharged from the circular guide portion 54 through the ball discharge passage to the game area 12 jumped up on the stage 50. Since the game ball does not collide with the game ball, the direction of discharge of the game ball discharged from the ball discharge passage does not change. As a result, the game ball is discharged from the ball rolling surface (from the ball discharge passage through the circular guide portion 54). The player's expectation for (emissions) is not impaired.

  In the present embodiment, the circular guiding portion 54 includes the wall portion 54a and the groove portion 54b, and the wall portion 54a protrudes so that substantially the entire game ball can be visually recognized. A groove may be formed so that substantially the entire game ball can be visually recognized from the surface of the portion 54, and the game ball may roll along the groove.
