In this case, the game ball is discharged at a position above the lower ball rolling surface, and the game ball discharged to the game area through the ball discharge passage collides with the game ball jumped on the lower ball rolling surface. Can be avoided.

(Solution means 33)
In the solving means 30 to the solving means 32, the ball rolling surface is configured such that the game balls rolling on the upper ball rolling surface and the lower ball rolling surface cannot contact each other.
In this case, the game ball rolling on the upper ball rolling surface does not come into contact with the game ball rolling on the lower ball rolling surface, so that the game ball rolling on the upper ball rolling surface is lower rolling It does not fall from the upper rolling surface to the lower rolling surface due to contact with the game ball rolling on the surface, and this may impair the player's expectation for the discharge of the game ball from the ball rolling surface. Absent.

(Solution 34)
In the solving means 30 to the solving means 33, the upper ball rolling surface is communicated with the one-way rolling permissible means for receiving the game ball from the path and rolling it in one direction, and the one-way rolling permissible means.

In this case, the one-way rolling permissive means for receiving the game ball from the path and guiding it to the annular rolling permissive means is constituted by the upper rail and the lower rail having different upstream end height positions. It is possible to vary the momentum (flowing speed) of the game ball induced by the above-mentioned, and to change the mode of the ball flow in the annular rolling allowance means. When the height of the upstream end of the upper rail and that of the lower rail are different, when the momentum of the game ball sent from the path is weak (the flow speed is slow), the upper end of the upper end is positioned higher. Since it is energized by being guided to the movement allowing means, the intended rolling is enabled by the annular rolling allowing means without depending only on the momentum of the game ball sent from the path. On the other hand, when the momentum of the game ball sent from the route is strong (the flow speed is high), the guide is sent from the route in order to suppress the momentum by guiding it to the annular rolling permissive means by one having a low upstream end height position. The intended rolling is enabled by the annular rolling allowance means without depending only on the momentum of the game ball.

(Solution 35)
In the solving means 34, the upper rail and the lower rail are installed close to the downstream portion of the path, and the path is a branch distribution that branches the game ball to the upstream end of either the upper rail or the lower rail. Means.
In this case, since the branch distribution means for suppressing the flow velocity of the game ball received at the downstream portion of the path and guiding it to one upstream end of the upper rail and the lower rail is provided, the game ball with the flow velocity suppressed It is urged by the upper rail or the lower rail to roll the annular rolling allowance means. For this reason, it is possible to roll the game ball according to the urging force by the upper rail and the lower rail without causing the entry speed of the game ball received in the path by the annular rolling allowance means.

(Solution 36)
In the solving means 35, the branch distribution means is a protruding member having a flat surface with a predetermined width dimension, and the surface of the protruding member is between the upper rail and the lower rail between the upper rail and the lower rail. Project so as to be higher than the height position.
In this case, since the surface of the projecting member is flat, the game ball flowing down the path comes into contact with the projecting member and is irregularly guided to the upper rail and the lower rail, and the distribution rate is biased. Can be prevented.

(Solution means 37)
In the solving means 36, the path has a bent part formed to be bent within the predetermined depth width, and has a width dimension of about one game ball on the downstream side of the bent part, and forms a substantially vertical path. And a distribution part which is located on the downstream side of the feeding part and in which the projecting member projects in the center of the width dimension in the depth direction of the feeding part.
In this case, the game ball fed from the bent portion by the feeding portion falls substantially vertically and comes into contact with a projecting member projecting at the center of the width dimension in the depth direction of the feeding portion. For this reason, the flow-down speed of the game ball can be substantially completely suppressed, and the uneven distribution ratio between the upper rail and the lower rail can be further prevented.

(Solution means 38)
In the solving means 34 to 37, the height positions at the upstream ends of the upper rail and the lower rail are made different.
In this case, the one-way rolling permissive means for receiving the game ball from the path and guiding it to the annular rolling permissive means is constituted by the upper rail and the lower rail having different upstream end height positions. It is possible to vary the momentum (flowing speed) of the game ball guided by the above, and to change the mode of the ball flow in the annular rolling allowance means.

(Solution 39)
In Solution 34 to Solution 38, on the passage outer wall of the path, an upper guide port for discharging game balls to the upper rail and a lower guide port for discharging game balls to the lower rail are visible from the front. Is drilled.
In this case, it can be clearly recognized whether the game ball is discharged from the upper or lower guide port. Note that, in this configuration, as in the present embodiment, depending on whether the game ball is discharged from the upper guide port or the game ball is discharged from the lower guide port, the game ball is subsequently won at the start port. If it is possible to roughly determine whether or not it is easy to do, it is possible to further enhance the interest of the ball flow of the game ball on the ball rolling surface.

(Solution means 40)
In the solving means 34 to 39, the annular rolling allowance means has a rolling surface on which a game ball rolls, and at least outside the rolling surface so that the game ball rolling on the rolling surface is visible. With protrusions.
In this case, since the protrusion is provided on the outer side of the rolling surface, the game ball that rolls the annular rolling allowance means does not fall on the lower rolling surface. It does not impair the player's expectation for emissions. In addition, since it is possible to visually recognize the game ball rolling on the rolling surface, it is possible to improve the player's interest in rolling the game ball.

(Solution 41)
In the solving means 40, the protrusion protrudes from the surface of the annular rolling allowance means at a height shorter than the diameter dimension of the game ball.
In this case, since the protrusion protrudes from the surface of the annular rolling permissible means at a height shorter than the diameter dimension of the game ball, the game ball rolling the annular rolling permissible means becomes visible, and the rolling of the game ball The interest of the player can be improved.

(Solution means 42)
In the solving means 34 to 41, the upper rail feeds a game ball to a depth position in the depth direction of the annular rolling allowance means, and the lower rail is located at a position in the depth direction of the annular rolling allowance means. The game balls are fed in, and the downstream portions of the upper rail and the lower rail are curved so that the game balls rolling on the upper rail and the lower rail are fed along the curvature of the annular rolling allowance means.
In this case, the game balls rolling on the upper rail and the lower rail are fed along the curvature of the annular rolling allowance means, and the game balls roll along the curvature of the annular rolling allowance means. The game balls that have rolled on the rails are sent to the annular rolling allowance means without losing the momentum of the game balls, so that it is possible to prevent the game balls from rolling in the annular rolling allowance means. In addition, since the height position of the upstream end of the upper rail and the lower rail is different, the mode of the ball flow of the game ball derived from one and the game ball derived from the other (the rolling of the game ball in the annular rolling allowance means) The range (number of rotations) can be changed.

(Solution means 43)
In Solution 34 to Solution 42, the height position at the upstream end of the upper rail is set higher than the height position at the upstream end of the lower rail.
In this case, since the height position at the upstream end of the upper rail is higher than the height position at the upstream end of the lower rail, the momentum of the game ball guided by the upper rail to the annular rolling permissible means is annularly rolled by the lower rail. The momentum of the game ball guided by the allowing means can be made stronger, and the upper rail can change the manner of the ball flow in the annular rolling allowing means. In addition, the height position at the upstream end of the upper rail that sends the game ball to the depth position in the depth direction of the annular rolling allowance means is the upstream position of the lower rail that sends the game ball to the front position in the depth direction of the annular rolling allowance means. Since it is higher than the height position and the visual recognition of the game ball sent by the upper rail is not hindered by the lower rail, even if the game ball rolls on the upper rail 52, the interest of the player is not lowered.

(Solution means 44)

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 (privilege grant determining means) 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 executes a game control program stored in the ROM 103 to control various games performed in the pachinko machine 1 and creates a signal to be transmitted to the peripheral board group and the payout board 105. The RAM 104 temporarily stores information such as various data generated in various processes executed on the main board 101 and 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, a signal instructing the payout board 105 to be paid out is transmitted from the CPU 102 mounted on the main board 101 to the payout board 105. 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.

  The payout board 105 is also connected to a launching device 135 having a launching motor that launches a game ball toward the game area 12. Then, based on the operation of the operation handle 18, the launching device 135 drives the launch motor to launch a game ball. Although not shown, the launching device 135 has a built-in touch sensor for detecting that the player is touching the operation handle 18. The touch sensor detects that the player is touching, and further controls the operation handle 18. Based on the operation of, the firing device 135 can drive the firing motor. 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 so as not to be accepted. In this case, it may be configured such that the operation of the operation handle 18 can be received based on the detection signal from the lower pan full switch being 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 (symbol display control means), an integrated ROM 113, and an integrated RAM 114. The sub-integrated board 111 also includes a sound source IC 128 that controls 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 the 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. The sound output mode is read from the sound ROM 127 based on the above, 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 subordinate. 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 61 to output a driving signal, the rotating member 61 is controlled to rotate, and by outputting the driving signal to the LED 61a, an afterglow in a predetermined manner is displayed. Further, the display CPU 121 mounted on the display control board 120 controls the image display device 42 based on the 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 game nail or the like. Then, when a 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 is displayed on the normal symbol display 44 (the LEDs are alternately lit in green and red). 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 the normal symbol display 44 starts to display the fluctuation of the normal symbol, it is determined whether or not to win based on the normal random number per symbol determination. (In this embodiment, the LED is stopped and displayed in red if it is a hit, and in green if it is off).

  In addition, the random number per 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 is executing the normal symbol variation display is It is possible to store up to a predetermined number (four in this embodiment), and the number of stored random numbers per ordinary symbol is displayed 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 number 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 it is lit red, and then the solenoid By moving 71a, the movable piece 71 is rotated to control the variable winning device 70 to be in an open state for a predetermined period. On the other hand, if it is determined to be off based on the determination random number 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 it is lit in green, and the variable winning device 70 is displayed. Do not control to open state. Specifically, when it is determined that the winning symbol is determined based on the normal random number per symbol determination, the normal symbol variation display is started. 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, when it is determined that the deviation is based on the normal random number per 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.

  Further, when the 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 to display the special symbols. 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 predetermined period of time, 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 a 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 the present 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 stoppage 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 symbol: In this embodiment, the combination of the same odd number symbols: Probability variation symbols, and after controlling to the big hit gaming state, the probability of the next big hit gaming state increases (in this embodiment, 1/70 in the probability variation state, 1/490 except for the probability fluctuation 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 from when the normal symbol is displayed until the normal symbol is stopped to a normal state, control for increasing the probability that the normal symbol variation display result of the normal symbol display unit 44 is “winning”, the normal symbol display unit 44. Control for extending the opening time of the movable piece 71 opened based on the fact that the normal symbol variation display is “win” at 44 (in this embodiment, 0.5% in the normal state). Control for increasing the number of times that the variable prize-winning device 70 is opened to the open state more than the normal state (in this embodiment, once in the normal state, the time is shortened). State and probability change In the state, three times), time reduction control and the like is also 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 combination of the same even number of symbols: non-probable variation), and after controlling to the big hit gaming state, the special symbol display 41 41 has a special number of special symbols (in this embodiment, 100 times). Control that shortens the fluctuation time of the special symbol and the fluctuation time of the normal symbol from the normal state until the fluctuation display of the normal symbol is executed. Time-shortening control such as control for extending the opening time of the movable piece 71 released based on the fact that the opening time of the movable piece 71 from the normal state, control for increasing the number of times the variable winning device 70 is opened to the open state, etc. is executed. Be doneIn 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 variation 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. When detected by the mouth switch 70b, four game balls are paid out. 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 game ball, the starting port (the first starting port 72 and the second starting port 73). ) Will be suppressed (by eliminating the disadvantages of the manager), 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 extension control of the opening time and the number of opening times of the movable piece 71, The winning probability for the second starting 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.

  In addition, the display result of the special symbol on the special symbol display device 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 unit 41 displays 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 (out-of-place symbol: symbol other than the jackpot symbol, book 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 effect different from the special symbols that are variably displayed on the special symbol display 41. The contents are displayed to the player with a more enhanced effect using a decorative pattern for performance. 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, but by any chance the display result of the decorative symbol on the image display device 42 is different from the specific display mode. Even if the LED in the special symbol display 41 is not lit and displayed in a specific display mode, the transition control to the big hit gaming state is not performed.

  Further, in this embodiment, 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, but the benefit given to the player as the big hit gaming state May be configured to be controllable to a plurality of types of big hit gaming states. 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 gaming 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 the present embodiment, the state display LED 45 is controlled to be turned on in red in the above-described probability variation state, and is controlled to be turned on 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 the control state is the big hit gaming state, the state display LED 45 is turned off.

  In the present embodiment, the jackpot type display LED 46 described above is turned on during execution of the jackpot gaming state. 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 configured to be controllable 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 the big hit gaming state.

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

  Next, various control processes executed in accordance with the progress of the game 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. 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) according to the game control program stored in the ROM 103. It is.

  When the game ball launched by the launching device 135 and flowing down from the upper part of the game area 12 toward the lower part 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 port 72 and the second start port 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 the game ball has won the first start port 72 and the second start port 73, various random numbers (for example, a jackpot determination random number, a probable variation determination random number, a reach determination random number, a variable display pattern random number, etc. 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, “1” is added to the on-hold ball number counter, and the lighting display mode of the special figure start memory lamp 47 (the number of lamps to be turned on) is changed in accordance with the addition of the on-hold ball number counter. The process and the process of storing the acquired 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. In addition, when 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 number 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 the 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, as shown in FIG. 7, the big hit determination random number, the probability variation determination random number, and the reach determination are included in various random numbers updated by the CPU 102 mounted on the main board 101 at a predetermined timing (in this embodiment, every 4 ms). There are random numbers, variable display pattern random numbers, normal random numbers 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 a 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 ends 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 display result of the normal symbol is a win (determination per normal symbol). 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 are 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. 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, it is first 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 variable 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 symbols are 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 prize memory provided in the RAM 104, the hold memory counter in the save area of the start prize memory 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 variation time to the variation timer. In the special symbol variation processing (step S15), when the variation display of the special symbol 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 pattern variation display to the sub-integrated board 111 is performed. In the big hit game process (step S17), it is determined whether or not the big hit flag, which will be described later, is in an ON state. Then, the control of the big hit gaming state, that is, the special winning 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) If 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 the ON state (step S35), then a probability variation determination table (not shown) in which a predetermined determination value 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 variation 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 the present embodiment, the probability variation intrusion rate (the ratio of probability variation big hit among big hits) is 2/3, that is, six decision values among nine probability variation determination random numbers from 0 to 8 are obtained. It is set in the probability variation judgment 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 transfer 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 variation state flag is set to the OFF state (however, if the probability variation state flag is already in the OFF state, 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. Note that the ON / OFF state of the big hit flag and the probability variation state flag is 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 variable display pattern setting process shown in FIG. 10, first, as a result of the current variable 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, a 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 variation display pattern table (not shown) showing a mode for deriving the outlier design with 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 determination 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 the variable display pattern random value read in the hold storage transfer process in step S13 is determined to be the same (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 a fluctuation display pattern of normal fluctuation, and when the time reduction control is executed, it is determined as a fluctuation display pattern of 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 special symbol variable display. Note that the sub-integrated board 111 performs control for starting the variation display of the decorative symbol based on the reception of the variation 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 to stop the special symbol variation display by the CPU 102 and transmits a display command for instructing the sub-integrated substrate 111 to stop the variation variation of the decorative symbol. Note that the sub-integrated board 111 performs control for stopping and displaying the decorative symbol based on the reception of the display command for instructing to stop the variable symbol display of the decorative symbol.

  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. 11 to 15. 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 and right edges (on the back side of the pachinko machine 1) of the center unit 40. A ball guiding member 65 (passage constituting member) 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 (path, passage main body) in which a downstream portion (a branch portion 673 described later) branches into two branches and guides the game ball to one of them, the swing passage member 43 and the ball. A connecting passage 66 that connects the passage member 49 to the branch passage 67, and the game balls that have entered the swing passage member 43 and the ball passage member 49 are discharged to the connecting passage 66 and then roll on the connecting passage 66. Then, the ball enters the branch passage 67 from the inlet of the ball guide member 65, flows down the branch passage 67, and is discharged from one of the upper guide port 68 and the lower guide port 69 that are outlets that discharge to the outside of the ball guide member 65. . The upper guide port 68 and the lower guide port 69 are examples of a plurality of discharge ports. The upper guide port 68 is an example of a first discharge port, and the lower guide port 69 is an example of a second discharge port.

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 moved in the depth direction (left side direction in the figure) and the near side direction (in the figure). A bent portion 671 (depth guide passage portion) that is caused to flow down while rolling in the right direction), and a game ball that is formed with a width of approximately one gaming ball and has flowed down the bent portion 671, is caused to flow substantially vertically. It consists of a feeding portion 672 as a feeding passage portion and a branching portion 673 (distribution portion) that branches into two branches and distributes to one of the upper guide port 68 or 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.

  Further, the bent portion 671 is composed of one 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, since the branch passage 67 is bent and formed with a predetermined distance width (passage width in the left-right direction in FIG. 12), the game ball that rolls in the bent portion 671 has its momentum (rolling). It is formed so as to collide with the inner wall of the branch passage 67 before the speed) increases and weaken its momentum, and the momentum (rolling speed) of the game ball entering the branch passage 67 can be suppressed or stabilized.

Note that the game ball guided in the forward direction (right direction 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 gaming ball, regulates the gaming ball and flows it down almost vertically (vertically), and sends it to the branching part 673. The branch portion 673 has a branch member 67a (branch vibration) protruding from the back surface (surface far from the stage 50) where the ball guide member 65 is not exposed at the approximate center of the width in the depth direction of the feeding portion 672. Wakebe material) is provided. Then, the game ball Q3 sent from the sending-in part 672 collides (contacts) the center part with the surface of the branching member 67a perpendicularly, and is guided 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 branching 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 is in contact with the branch member 67a from being caught in the branch passage 67 and causing a ball clogging.

  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 completely stop the momentum.

  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, so that the load on the branching member 67a is reduced. This can reduce the length of the branching member 67a. Furthermore, in this embodiment, the game ball flowing down the branch passage 67 collides with the upper portion of the branch member 67a, but the branch member 67a has a narrow vertically long shape (in FIG. 12, the width dimension in the left-right direction is small and the vertical direction The durability of the branching member 67a is enhanced.

  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 the present 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 position 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.

  The ball guiding member 65 that forms the branch passage 67 is made of a transparent synthetic resin material (for example, polycarbonate). Thereby, the game ball passing through the branch passage 67 is configured to be visible to the player. The branch passage 67 includes a passage bottom wall, a passage inner wall, and a passage outer wall. The wall surface portion 65a of the sphere guide member 65 serving as the passage outer wall of the branch passage 67 (passage outer wall, sphere viewing portion, outer wall of the route) ) Is the center of the stage 50 as shown in FIGS. 13A and 13B (in the figure, the ball guide member 65 located at the right end of the stage 50 as viewed from the player side is illustrated). It is formed in a curved surface shape that rises to the side. Further, as shown in FIG. 13A, the bent portion 671 of the branch passage 67 having such a curved-surface-shaped passage outer wall (wall surface portion 65a) has a passage outer wall positioned at the front position of the pachinko machine 1. The stage 50 is extended with a slight inclination angle (smooth curved surface) with respect to the depth width direction (front-rear direction) of the stage 50 so that the player can visually recognize it. In other words, the bent portion 671 of the branch passage 67 that guides the game ball in the front-rear direction and the left-right direction with respect to the depth width of the stage 50 is, as viewed from the front, the downstream side (the communication side with the feeding portion 672) is the upstream side (connected). The extending direction of the passage is set so as to be located on the outer side as compared with the communication side with the passage 66. Thereby, the game ball flowing down in the bent portion 671 is gradually guided to the outside along with the flow down. Therefore, when a plurality of game balls pass through the bent portion 671, the game ball R1 passing through the downstream side of the bent portion 671 is positioned outside the game ball R2 passing through the upstream side of the bent portion 671. Thus, the game balls R1 and R2 do not completely overlap in front view. In addition, according to the structure of embodiment, since a depth guidance path part is formed by one path part (it is different from the structure which connected the several channel | path part), a game ball can be guide | induced smoothly. .

  Further, the upper guide port 68 and the lower guide port 69 described above are formed in the curved outer wall (wall surface portion 65a) of the curved surface of the branch passage 67, but the wall surface portion 65a is the depth of the stage 50. By extending with a smooth curved path with respect to the width direction (front-rear direction), each guide port 68 and 69 can be visually recognized by the player whose opening is the front position of the pachinko machine 1. It has become. That is, when viewed from the front, the opening portion of the lower guide port 69 can be visually recognized at the outer portion with the branch member 67a as a boundary, and the open portion of the upper guide port 68 can be visually recognized at the inner portion with the branch member 67a as the boundary. For this reason, as shown in FIG. 13B, the game balls R3 distributed to the lower guide port 69 side by the branch member 67a are openings (lower guide ports 69) located on the outer side in front view with the branch member 67a as a boundary. The game ball R4 distributed to the upper guide port 68 side by the branch member 67a is discharged from an opening (upper guide port 68) located on the inner side in front view with the branch member 67a as a boundary. Thus, it is possible to clearly recognize which guide port 68, 69 the game ball is discharged from.

  The game ball discharged from the upper guide port 68 is guided to the circular guide portion 54 via the upper rail 52 described later, and the game ball discharged from the lower guide port 69 passes through the lower rail 53 described later. The game ball that is guided to the circular guide portion 54 is sent to the circular guide portion 54 more vigorously than the game ball that has flowed down the upper rail 52, so that a later-described guide passage 58 is provided. As a result, it is easy to win the start opening (first start opening 72) (details will be described later). Accordingly, whether or not the game ball is likely to win the start port (first start port 72) afterwards depending on whether the game ball is discharged from the upper guide port 68 or the game ball is discharged from the lower guide port 69. Can be roughly determined. For this reason, the structure which can recognize clearly from which guide port 68,69 the above-mentioned game balls are discharged | emitted is on stage 50 (it contains the upper rail 52, the lower rail 53, and the circular guide part 54). It is designed to further enhance the fun of the ball flow of the game balls. The circular guiding portion 54 is an example of an annular rolling allowance unit. The surface of the circular guiding portion 54 is an example of a rolling surface. The upper rail 52, the lower rail 53, and the circular guide 54 are examples of the upper ball rolling surface. On the other hand, the stage 50 and the ball receiving stage 80a are examples of a lower ball rolling surface. Further, the upper rail 52, the lower rail 53, and the circular guide portion 54 are examples of rail-shaped passages. The upper rail 52 and the circular guide portion 54 are an example of a first guide passage, and the lower rail 53 and the circular guide portion 54 are an example of a second guide passage. The upper rail 52 and the lower rail 53 are examples of receiving rails. The circular guiding part 54 is an example of a feed-in rail.

  In addition, an LED substrate 94 (light irradiation means) on which a plurality of LEDs 95 are mounted is provided on the back side of the ball guiding member 65 (branch passage 67) formed of a transparent synthetic resin material. The light emitted from the LED 95 is irradiated from the back side of the branch passage 67 through the transparent ball guide member 65 to the center side of the stage 50, so that the entire ball guide member 65 including the branch passage 67 is light-decorated. It has become. Further, it is easier for the player to see which part of the game ball passing through the branch passage 67 is passing through the branch passage 67 by the light emission of the LED 95.

  FIG. 14 is a perspective view of the game board 4 as viewed from the front upper side. Further, as shown in FIGS. 11 and 14, 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. In addition, 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 (guidance passage) having a passage shape for one game ball is formed at the center of the stage 50. In addition, the guide passage 58 descends below the stage 50 and bends and extends from there to the front surface side, and is connected to the discharge port 51 (ball discharge portion) formed at the center of the lower outer wall of the front decorative body 80. 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. By doing so, it becomes easy 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 (a position closer to the first start port 72 than the discharge stage 80a), and is connected to the guide passage 58. It is formed in an opening shape for one connected game ball. For this reason, the game ball discharged from the discharge port 51 can easily win the first start port 72 with a high probability (probability close to 100%). The discharge port 51, the upper guideway 55, the lower guideway 56, and the guide passage 58 are examples of a ball discharge passage.

  In addition, a plurality of support members 57 having a predetermined height (in this embodiment, a height equal to or larger than the diameter dimension of the game ball) are formed on the surface of the stage 50 so as to protrude from the upper surface of the stage 50. A hollow circular guide 54 (which forms the shape of an annular sphere guide passage) is formed in the forward direction 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 guiding portion 54 has a wall portion 54a (both side wall portions as a spherical guiding passage: a protruding portion) that protrudes upward from the surface of the circular guiding 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 of the inner periphery. Further, the support member 57 has a cylindrical 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 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 the present embodiment, the groove 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, so that the rotation of the game ball in the circular guide portion 54 is increased. Each movement can have a change. In the present embodiment, the outer peripheral and inner peripheral wall portions 54a of the circular guide portion 54 are formed so as 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. It is possible to visually recognize substantially the entire game ball rolling on the groove portion 54b of the guide portion 54.

  In the present embodiment, the circular guide portion 54 is placed so as to be inclined at a predetermined angle toward the front side of the pachinko machine 1, but the wall portion 54a is formed to protrude 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 guiding portion 54. In the present embodiment, the wall portion 54a is formed to protrude so as to have a height smaller than the diameter of the game ball so that the game ball rolling on the groove portion 54b can be visually recognized. However, the wall portion 54a is transparent. By forming the resin 54 (for example, acrylic resin such as ABS resin), the wall 54a protrudes from the upper surface of the circular guide 54 (groove 54b) at a height that is equal to or greater than the diameter of the game ball. You may form.

  Moreover, the wall part 54a of the inner periphery of the circular guide part 54 has a notch part from which a part thereof is cut off. In the present 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 inner peripheral front side, and the inner peripheral front side. The cutout 54d on the side has a wall 54a cut out over a wider area than the cutout 54c on the inner peripheral back side, and a groove 54b corresponding to the cutout 54d on the front side on the inner periphery (notch on the front side on the inner periphery in the groove 54b) The portion 54d of the portion 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 so 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. 15, the upper rail 52 and the lower rail 53 form a rod-shaped rail member 59a (bar-shaped member) that forms both side wall portions of the guide passage and a bottom portion of the guide passage, respectively. And a sleeper member 59b that increases the strength of the rail 52 and the lower rail 53 and keeps the distance 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 turned. The moving 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. 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 of flowing down to the circular guiding portion 54 is restricted, and one direction, that is, circular guiding is performed. Rolling in the direction of flowing down to the part 54 is permitted.

  Further, 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. For this reason, the game balls rolling on the upper rail 52 and the lower rail 53 are guided to the circular guide portion 54 without losing their momentum.

  It should be noted that the interval between the rail members 59a may be equal to or greater than the diameter dimension of the game balls so that the game balls roll on the sleeper members 59b. In this case, the rail members 59a are separated from the upper surface of 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 the present embodiment, since 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 dimension 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 contact 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 portion The interest of the player is reduced by lowering the winning rate to the starting opening (the first starting opening 72 and the second starting opening 73) when rolling the rail 52 and the lower rail 53. Can be prevented.

  Note that 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, so that 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 guiding portion 54 rolls on the groove portion 54 b, falls from one of the cutout portions 54 c and 54 d of the circular guiding portion 54, and is discharged from the circular guiding 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 ball discharged from the notch 54d on the front side of the inner periphery can be guided to the guide passage 58 through the lower guiding path 56, but the lower guiding 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 to the surface of the stage 50, roll in the front 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. 15 is a longitudinal sectional view showing the circular guiding portion 54. As shown in FIG. 15, when a 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 opening (first start opening 72) (probability close to 100%).

  Next, the flow of game balls discharged from the notch 54d on the front side on the inner circumference 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 again from the discharge port 51 to the game area 12. 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 almost 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 in the forward direction 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 on 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.

  Note that the game ball that has flowed down the upper rail 52 and is vigorously sent to the circular guiding portion 54 rolls on the circular guiding portion 54 vigorously and is easily sent to the upper guiding path 55 or the lower guiding path 56 as it is. ing. For this reason, the game ball that has flowed down the upper rail 52 is easier to enter the guide passage 58 than the game ball that has flowed down the lower rail 53, and is easy to win a start opening (first start opening 72).

  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. Accordingly, 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 part 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 jumped up game balls, so that the start port (the first start port 72 or the second start port 73) wins a prize. There is no case where the game balls P1 and P2 are discharged in a direction where there is no possibility of doing so.

Further, in the present embodiment, the height position of the upstream end portion (upper guide port 68) of the upper rail 52 as the upper sphere passage is higher than the lower rail 53 (lower guide port 69) as the lower sphere passage. Is arranged. 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 sent to the circular guide portion 54. Therefore, the game ball that has flowed down on the upper rail 52 rolls on the circular guiding portion 54 (moving width: the outer circumference of the circular guiding portion 54) compared to the game ball that has flowed down on the lower rail 53. The number of rotations that move) increases. In this way, 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 the present 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 more than the upstream end of the lower rail 53. Since the height position from the surface of the stage 50 is configured to be high, the lower rail 53 does not hinder the visual recognition of the game ball rolling on the upper rail 53 disposed 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 or the lower guide port 69 is used as the lower rail. 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 inclination 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. For this reason, it becomes possible to roll the game ball sufficiently with the circular guiding 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 its performance. Can be fully demonstrated. That is, the rolling width of the game ball in the circular guiding portion 54 is caused only by the momentum (rolling speed) urged 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 the present 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 notches 54c and 54d, whereby the guide passage 58 or the stage 50 is used. The circular guide portion 54 is formed in a circular shape (not hollow) having a plurality of holes, one of the plurality of holes communicates with the guide passage 58, and the other hole is connected to the guide passage 58. You may make it form so that it may not be connected. 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 be guided to the upper guide path 55 and the lower guide path 56 increases along the groove 54b of the circular guide section 54. 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 the present embodiment, a member shaped like a bell is formed at the tip, and a lamp is built therein. Further, in the present embodiment, the special figure start memory lamp 47 is the left front part of the stage 50, two in the position closer to the front side of the pachinko machine 1 than the lower rail 53, and the right front part of the stage 50. A total of four protrusions are formed 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 formed at the tip of the special-purpose start memory lamp 47 all coincide. It is formed.

  Next, with reference to FIG. 16, the rotating accessory 61 provided in the upper right part of the front of the center unit 40 will be described. FIG. 16 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 the present embodiment includes LEDs 61 a capable of emitting multicolor light as a plurality of (eight in the present embodiment) light emitters.

  In the present embodiment, a rotating accessory 61 is provided on the front upper right portion 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. For this reason, in this embodiment, the rotation accessory 61 is provided in the front upper right part of the center unit 40 corresponding to the front right upper part of the game area | region 12 which has the least influence on a player's game.

  As shown in FIG. 16, 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 includes a rotating accessory body 62 provided with various substrates, and a mounting substrate 64 that is screwed to the rotating accessory 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 referred to as 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. 17B). ). 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, 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, etc. The board on which is mounted.

  In the present embodiment, the upper part is formed substantially in parallel with the front plate 611 from the bottom plate 614 toward the front plate 611, and a plurality of pieces are formed so as to protrude from the one of the side plates 612 and 613 toward the inner side of the rotary member 61. The holding part 614a is 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. In other words, 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. 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 614a 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 from the bottom plate 614 side with screws 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. Accordingly, when the rotating member 61 is rotated by being firmly fixed inside the rotating member 61, it rotates integrally with the rotating member 61.

  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 member 61, air flows from the vent hole 61 b and circulates the air inside the rotating member 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, etc. generate heat when operating, and there is a possibility that the solder melts and peels off from the substrate or a contact failure occurs. For this reason, the air 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, IC, condenser, etc., thereby suppressing the temperature rise. is doing. Further, 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.

  17A is a side view of the rotating unit 60, and FIG. 17B is a cross-sectional view of the rotating accessory 61 cut along the XY plane in FIG. 17A.

  Although not shown in FIG. 17B, the board 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. As shown in FIG. 17B, the motor shaft 63a of the motor 63 is provided at the center of the bottom plate 614 of the rotating accessory 61 (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, in the present embodiment, the rotating combination 61 has the same length from the motor shaft 63a on one end side in the longitudinal direction of the bottom plate 614 and the length on the other end side in the longitudinal direction of the bottom plate 614, and from the motor shaft 63a. The length of one end side of the bottom plate 614 in the short direction is the same as the length of the other end side of the bottom plate 614 in the short direction.

  In the present 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 along the center line in the lateral direction of the substrate in the region on one end side where the LED 61a is mounted, and the lateral direction of the substrate is disposed on the rear surface of the substrate in the region on the other side where the LED is not mounted. A capacitor is mounted along the center line. Further, in the present embodiment, the IC is installed at a position close to the longitudinal direction of the substrate from the rotation axis of the rotating combination 61 (the center of the rotating combination 61), and the capacitor is connected to the rotation axis of the rotating combination 61 (of the rotating combination 61). By installing each member along the center line in the lateral direction of the substrate, the LED 61a and the IC are installed at a position far from the center) in the longitudinal direction of the substrate (a position close to the longitudinal end of the substrate of the rotating accessory 61). 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 into 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, and the center of gravity of the rotating combination 61 matches the rotation axis of the rotating combination 61. Therefore, it is possible to prevent centrifugation and to reduce vibration generated by centrifugation. Furthermore, 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 accessory 61 at a high speed by driving the motor 63 at a high speed based on a driving signal from the accessory CPU 116 (1200 rotations per minute in this embodiment). Let 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 rotational speed of the motor 63. In the present embodiment, it was possible to display an afterimage by rotating the motor 63 at a rotation speed of 600 rotations per minute. However, in order to display a more beautiful afterimage, 1200 rotations per minute. A certain number of rotations is required. 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 modes 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 displayed in the afterglow. The number of LEDs 61a to be mounted can be reduced as compared with the case where no display is performed, and there is an advantage that the manufacturing cost of the pachinko machine 1 can be reduced. However, in order to display the afterglow, 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 are increased. 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.

  18 is an exploded perspective view of the center unit 40 as seen from the front side of the game board 4, and FIG. 19 is an exploded perspective view of the center unit 40 as seen from the back side of the game board 4. FIG. 20 is a rear view of the game board 4, and FIG. 21 is a rear perspective view of the game board 4.

  As shown in FIGS. 18 and 19, the center unit 40 of this embodiment includes a front decorative body 80 and a rear unit 83 that are divided forward and backward with the game board 4 interposed therebetween. Specifically, a front decorative body 80 is located on the front side of the game board 4, and the front decorative body 80 is attached to the game board 4 from the front side. Conversely, on the back side of the game board 4, a rear unit 83 composed of an attachment unit 81, a back decoration body 82 (decoration member), and a rotation unit 60 including a rotating accessory 61 is located. 4 from the back side. Further, the back decoration body 82 includes a mounting substrate 86, a ball guide member 65, a stage unit 50a excluding the ball receiving stage 80a formed on the lower edge portion of the front decoration body 80 of the stage 50, and an upper decoration body. 87, and a display unit 85 including the image display device 42 and the display control board 120.

  Further, the game board 4 is formed with a through hole 4a formed by punching the plywood material in the thickness direction. The through hole 4a is greatly opened from the center of the game area 12 to a slightly higher range, and the opening shape substantially matches the outer shape of the front decorative body 80. The front decorative body 80 attached from the front side of the game board 4 among the members constituting the center unit 40 has a hollow shape in which the center portion and the upper right portion are drawn out in the thickness direction.

  The mounting unit 81 located closest to the game board 4 in the rear unit 83 has an opening cut out in the thickness direction from the center to the upper right part, and a plurality of boss holes 81a are formed on the front side. A boss 81b is formed on the upper rear side of the opening formed in the upper right portion of the mounting unit 81. A plurality of bosses 81 c are also formed on the back side of the mounting unit 81. Further, the attachment unit 81 is shaped so that the front surface facing the back surface of the game board 4 is almost flat, and is attached so that the flat front surface is in contact with the game board 4. When the rear unit 83 is attached to the game board 4, the flat front surface comes into close contact with the back surface of the game board 4 (however, a gap due to manufacturing error or distortion is allowed).

  Further, although the flat front surface of the mounting unit 81 is not fitted into the through hole 4a, a part thereof is in a positional relationship facing the through hole 4a. That is, when the attachment unit 81 is attached to the game board 4, the front surface thereof partially protrudes inside the through hole 4 a and is exposed to the front side of the game board 4 through the through hole 4 a. However, since this exposed part is covered with the front decorative body 80, it is not directly visible to the player.

  Further, the back surface decoration body 82 located on the back surface of the mounting unit 81 includes a mounting substrate 86 having a hollow shape with a central portion pulled out in the thickness direction, a stage unit 50a mounted below the opening of the mounting substrate 86, and a mounting unit.

In addition, 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 is set to have a thickness almost the same as the thickness of the game board 4 when viewed in the front-rear direction. 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 the present 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 position each other. Attachment 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 of the front body protrudes 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 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 mounting substrate 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 50a, the upper decorative body 87, and the display unit 85 attached from the rear 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 to serve as a blindfold that makes the back 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 penetrates the upper right part of the opening of the front decorative body 80 and protrudes to the front 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 directly visible to 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 the present 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. For this reason, the rotation unit 60 can be screwed to the game board 4 by screwing with screws using the other holes of the mounting holes 64a. That is, the mounting hole 64a has a spare hole.

  22 is a cross-sectional view of the game board 4 cut along the ST plane, and FIG. 23 is an enlarged view of FIG. 22 (B).

  As shown in FIG. 22B, in this embodiment, the stage 50 further has a predetermined width in the depth direction (pachinko machine 1 depth direction) from the back of the game board 4, and the end of the stage 50 in the depth direction. The image display device 42 is located at the part 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, the rotating combination 61 is disposed away from the image display device 42 by a predetermined distance (distance that sandwiches the stage 50 provided in the center unit 40). 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 effect can be achieved 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.

  In addition, 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 82. Specifically, as shown in FIG. 23, 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, whereby the mounting unit 81 and the rotating unit 60. However, the other portions are not in contact with the rotating unit 60 in a state of being shifted in the vertical and horizontal directions and the front and rear directions in FIG.

  As described above, the game balls that have been inserted into the guide passage 58 provided in the stage 50 are likely to win the first start port 72 and the second start port 73, so that if the stage 50 vibrates, the stage 50 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 at the first starting port 72 and the second starting port 73 is affected, which is disadvantageous to the player.

  In this 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 the 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 surface decoration body 82 attached from the back side of the game board 4 are made of synthetic resin or the like and become light. For this reason, when the rotation unit 60 is screwed and driven to the attachment unit 81 and the back surface decoration body 82, vibration generated by driving the rotation unit 60 is easily propagated. Further, since the back surface decoration body 82 includes a stage unit 50a that constitutes a part of the stage 50 and is related to winning in the first start port 72 and the second start port 73, vibration propagates to the back surface 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 are provided and various apparatuses such as the image display device 42 are attached. Become. As described above, since the game board 4 is heavy, when the rotary unit 60 is attached to the game board 4 and driven, vibration generated by driving the rotary 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 the present embodiment, the mounting unit 81 and the rotating unit 60 are in 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. However, 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 the present embodiment, the boss 81b formed on the mounting unit 81 is inserted into the boss hole 62a formed on the rotating accessory body 62 of the rotating unit 60, so that a part of the mounting unit 81 and the rotating unit 60 is partly inserted. Although configured to contact, 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.

  Further, in the present embodiment, a method of attaching the game board 4 to the pachinko machine 1 is devised in order to suppress vibrations generated by driving the rotary unit 60. This will be described below. FIG. 24 is a front view of the pachinko machine 1 with the game board 4 attached and the front frame 5 removed. FIG. 25 is an enlarged view of the mounting mechanism of the game board 4.

  As shown in FIG. 24, 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, and two engagement recesses 36 are formed on the upper and lower sides of the right side of the game board mounting frame 9, and two are formed on the upper and lower sides of the right side of the board 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. 25, 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 for engaging and fixing 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 clamps 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 it 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 for operating 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. Then, by operating the handle portion 35b and moving the engagement hook 35 to the LOCK position, the locking portion 35a protrudes outside the game board 4 and can be locked with the engagement recess 36, and the handle portion 35b. Is operated to move the engagement hook 35 to the UNLOCK position, so that the locking portion 35a is retracted without protruding to the outside of the game board 4 and cannot be locked to the engagement 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. In other words, 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 provided in the game board 4 and located above and below the storage recess 39. A protruding 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 engagement hole 34 formed on the left side of the game board 4 is brought into contact with the engagement protrusion 33 formed on the left side of the game board mounting frame 9, the left side of the game board 4 is rotated about the rotation axis. And the engagement board 34 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 in which the engagement hook 35 is restrained at 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 locking portion 35a protrudes to the outside of the game board 4 and engages with the engagement recess 36 formed in the game board mounting frame 9. At the same time, the game board 4 is pressed by pushing the game board 4 in the back direction of the pachinko machine 1. Is fixed to the game board mounting frame 9 is engaged.

  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.

  Thus, in the present embodiment, the left side of the game board 4 is engaged by the engagement protrusion 33 and the engagement hole 34, and the engagement portion 35a is inserted into the engagement recess 36 to be engaged. By pressing the game board 4 in the depth direction of the pachinko machine 1, the game board 4 is firmly fixed and locked to the game board mounting frame 9. In the present 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, 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. Suppressed, the game board 4 can be securely fixed to prevent the occurrence of vibration, and the rolling of the game ball flowing down the surface of the game board 4 is not affected.

  Further, in the present embodiment, the rotating accessory 61 is attached so as to be located on the upper right side of the game area 12, and the engaging hook 35 is located in the vicinity thereof. As described above, the engaging hook 35 and the engaging recess 36 are located. And the game board 4 is firmly fixed. For this reason, 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. In addition, 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 so as to be positioned in the vicinity of the locking hook and the urging 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 so that there is no play, but the engagement protrusion 33 and the engagement hole 34 are engaged so as to have some play. Suppressive effect is weak.

  Further, when the rotating combination 61 is directly screwed to the gaming board 4 fixed to the pachinko machine 1 in this way, vibration from the rotating unit 60 is difficult to propagate to the gaming board 4 and the rotating combination 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 the present 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. By configuring in this way, 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, the 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 an impression that the rotating combination 61 is raised in front of the image display device 42 and to provide a three-dimensional feeling 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.

  In the state where 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, the stop position of the rotating accessory 61 shown in FIG. 22). Even when the motor 63 is driven to rotate the rotating combination 61, when the motor 63 is stopped, the rotating combination 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 the present 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 rotating 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. Based on the signal, one of a plurality of types of light emission patterns stored in the accessory ROM 117 is selected, 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 rotary combination 61 is driven to rotate in a predetermined light emission pattern, and the rotary combination 61 is placed inside the rotary 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. 26 shows an example of an afterglow displayed by the rotating combination 61.

  As shown in FIGS. 26A to 26C, the fireworks shown in FIG. 26A are controlled by controlling the light emission of the LED 61a with a predetermined light emission pattern when the rotary member 61 is driven to rotate. A cloud shown in B), a lightning shown in FIG. 26C, 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. For this reason, it becomes easier for the player who is paying attention to the image display device 42 to recognize that the rotating combination 61 has been driven, and it is possible to focus on the afterglow displayed on the rotating combination 61. It becomes. 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.

  26A to 26C, the image display device 42 located behind the afterglow displayed on the rotating combination 61 is in a transparent state. That is, in the present 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, but as described above, the rotating combination 61 is rotated at a high speed by the motor 63. (The number of rotations is 1200 revolutions per minute), the time required for the rotating agent 61 to pass so as to cover a part of the image display device 42 is shortened, and the image display device 42 on the back side of the rotating agent 61 is seen through. can do. 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. In addition, you may comprise so that LED61a may be mounted ranging from the longitudinal direction one end of the surface of the rotation accessory 61 to a longitudinal direction other end, In this case, the rotational speed of a motor is set to the rotational speed (1) of this embodiment. Although it is possible to display a beautiful afterglow (for example, 600 revolutions per minute), the brightness of the afterglow displayed when the number of LEDs 61a increases (for example, 600 revolutions per minute) can be displayed. (Brightness at a predetermined position) is increased, and there is a problem that it becomes difficult to see the display of the image display device 42 located on the back side of the afterimage. 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.

  In addition, as described above, in the present 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, an afterimage is obtained by inserting a motor shaft substantially perpendicular to the game board 4 at the longitudinal end portion of the rotating accessory and rotating it around the longitudinal end portion of the rotating accessory and controlling the light emission of the LED. It is also possible to display. However, since the motor shaft and the center of gravity do not coincide with each other, the load applied to the motor increases, and it is difficult to rotate the motor at high speed, and it is difficult to suddenly rotate and stop suddenly. 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 accessory, and the afterglow is displayed by reciprocating driving around the longitudinal end portion of the rotating accessory and 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 the state driven to one side, the afterglow of the part stopped at one end Brightness (luminance at a predetermined position) increases. In addition, since the rapid rotation and the sudden stop are repeatedly performed, 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 on the game island 4 with a part of the drum, reel, etc. entering the back of the game board 4, the area of the back of the game board 4 is limited. It was difficult to increase the size of reels and the like. That is, when the pachinko machine 1 is attached to the amusement island, the area on the back of the pachinko machine 1 can be used only in an area where the pachinko machines 1 that are back to back are not in contact with each other. is there.

  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 area 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.

  The lamp used in the present embodiment is an example of a light emitter, and is not limited thereto. That is, the device configured using the 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. In other words, in this embodiment, a plurality of types of modes are displayed by light emission points (dots) from the individual LEDs 61a. However, by directly translating a part of the front plate 611 located in front of the LEDs 61a, the LEDs 61a can be directly connected. Further, 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, so that a smooth mode can be displayed.

  In the present 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, but 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 fact that the power supply is stopped. Thus, the rotating accessory 61 may be stopped. It should be noted that vibration is greatest when the rotating combination 61 is rotated and when the rotation of the rotating combination 61 is stopped. For this reason, while the electric power is supplied to the pachinko machine 1, the generation of vibration is suppressed by continuously rotating the rotating accessory 61 so that the game ball that rolls on the stage 50 is rotated. It does not affect the movement and rolling of the game ball flowing down the game area 12.

  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.

  Further, in the present embodiment, eight LEDs 61 a are mounted on the rotating combination 61, but a rotating shaft is inserted in the center of the rotating combination 61, and the rotational axis of the rotating combination 61 and the center of gravity of the rotating combination 61 are included. The number of LEDs to be mounted is not limited. Further, when the rotation axis of the rotating combination 61 and the center of gravity of the rotating combination 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 combination 61 (outside the bottom plate 614). It may be adjusted to keep the weight balance even.

  In addition, you may comprise so that several 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 When the rotation unit 60 is configured to be capable of rotating at a rotation speed of 1800 rpm and the special symbol display 41 starts the variable display of the special symbol (the image display device 42 starts the variable 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 disengaged. By configuring so as to increase, the expectation of big hit (ratio of big hit) 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 passage outer wall of the branch passage 67 including the bent portion 671 is formed of a transparent material, and the bent portion 671 is formed in the front-rear direction and the left-right direction with respect to the depth width. By providing a smooth curved surface, even when a plurality of game balls enter the branch passage 67, the game balls do not completely overlap in a front view, and all the ball flows of the game balls in the branch passage 67 are confirmed. be able to. Further, according to this configuration, the bent ball 671 guides the game ball in the front-rear direction and the left-right direction with respect to the depth width of the stage 50 to weaken the flow velocity of the game ball passing through the branch passage 67, and at a stable flow velocity. A game ball can be sent to the ball rolling surface. In addition, in embodiment, although it comprises by forming a channel | path outer side wall with a transparent material as a ball | bowl visual recognition part which concerns on this invention, it is not restricted to this, The opening part pierced by the channel | path outer side wall is made into a sphere. It is good also as a visual recognition part. Moreover, although the guide surface part which concerns on this invention is comprised from the smooth curved surface, you may comprise from the flat surface extended not only in this but linearly.

  Further, according to the configuration of the present embodiment, the branch passage 67 is disposed on the side portion of the decorative member (the front decorative body 80 and the back decorative body 82). For this reason, without increasing the lateral width of the side of the decorative member (even when the image display device 42 is configured to have a large display screen, the center accessory having the branch passage 67 itself can be extremely enlarged. No), it is possible to increase the guidance distance of the game ball in the branch passage 67 and to improve the interest in the ball flow. Further, the center accessory (the image display device 42 and the decorative member) is disposed at a substantially central position of the game area 12. For this reason, the game area 12 on the left and right sides of the center object, that is, the ball passing area on the left and right sides of the center object can be sufficiently taken, and the ball flow of the game ball in the game area 12 is hindered. Never come.

  Further, according to the configuration of the present embodiment, the bent portion 671 is a multi-layered passage that is bent and formed within the depth width of the stage 50 and connected to the end portions thereof. Thereby, the flow speed of the game ball passing through the branch passage 67 can be surely weakened, and the game ball can be sent to the ball rolling surface with a more stable flow speed. The passage outer wall (wall surface portion 65a) of the branch passage 67 including the bent portion 671 is formed in a curved surface shape. Thereby, the design of the branch passage 67 can be warmed by making the outer wall of the branch passage 67 round.

  The branch passage 67 includes a spherical guide member 65 that uniformly forms the passage main body (the bent portion 671, the feeding portion 672, the branch portion 673) and the passage outer wall (wall surface portion 65a). Thereby, the operation | work which assembles a channel | path main body and a channel | path outer side wall becomes unnecessary, and can improve the assembly | attachment workability | operativity of a structural member. In addition, on the back side of the branch passage 67, light irradiation means (LED substrate 94) that irradiates light toward the outer wall of the branch passage 67 is provided. Thereby, the branch passage 67 can be light-decorated, and it can be more easily seen which part of the branch passage 67 is passing the game ball. The light irradiating means includes an LED substrate 94 on which a plurality of LEDs 95 are mounted. Thereby, it is possible to irradiate light over the entire branch passage 67 by simply attaching the LED substrate 94 to the back side of the branch passage 67.

  In general, in the case where the frequency (start winning rate) of the start winning (the winning of game balls to the first starting port 72 and the second starting port 73) is suppressed at the game hall side, In the embodiment, the guidance of the game ball by 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 the present 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 has been formed in the form of a continuous series of steps. 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 to reduce 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 caused by 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 in 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 A game ball on the surface It does not reduce the interest in the record.

  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.
