  Next, the operation of the pachinko gaming machine according to the present embodiment will be described.

  When the game ball 27 bulleted by the player enters the ball inlet 86 of the ball channel 53 or 54 in the process of dropping the game area 3, the game ball 27 passes through the first channel 87 and the second channel 88, Rolls out from the ball exit 89 to the stage 84. Then, the game ball 27 rolling out in the right direction from the ball flow channel 53 on the left side of the front face collides with the ball guide projection 99 through the first rolling surface 94 and turns backward, The rolling surface 95 and the central rolling surface 96 roll to enter either one of the left and right ball introduction holes 97 and 98. On the other hand, the game ball 27 rolling out to the left from the front right-hand ball passage 54 rolls on the ball rolling guide path 100, then rolls on the central rolling surface 96, and either one of the right and left ball introduction holes. Enters 97 and 98.

  In this way, for example, when the game ball 27 enters the ball introduction hole 97 on the left side of the front, it passes through the left distribution channel 105 from the ball inlet portion 103, and the ball path distribution means on the left side from the ball outlet portion 107. 25, and enters the first sphere receiving portion 74 or the second sphere receiving portion 76. At this time, since the central rolling surface 96 has a symmetrical shape and the ball introduction holes 97 and 98 have the same diameter, the game balls 27 are equally distributed to the left and right.

During this time, the rotation direction of the ball path distribution unit 25 is controlled by the accessory (game part) control unit 29 of the game control device 20 together with the rotating body 52. That is, when the first slit hole 65 of the first sensor detection piece 67 passes between the light emitting unit 69 and the light receiving unit 70 of the first photosensor 58 when the rotating body 52 is rotating forward in the clockwise direction when viewed from the front, As shown in FIG. 12, a detection signal is sent from the first photosensor 58 to the rotating body drive control means 11, and the direction switching control means 113 of the rotating body control means 11 stops the rotating body drive motor 55 after decelerating. . When a predetermined time, for example, t seconds elapses after the rotating body drive motor 55 stops, the direction switching control means 113 starts and rotates the rotating body drive motor 55 counterclockwise this time, and the rotating body 52 is rotated at a predetermined speed. Rotate counterclockwise with. In this case, each time the rotating body 52 rotates once and the first photo sensor 58 detects the first slit hole 65, the rotating direction of the rotating body 52 is switched between forward and reverse. The rotation driving control means 11, after rotating body driving motor 55 is started, from the time t ₂ required to reach the predetermined speed, the rotational body driving motor 55 is decelerated, a long time t ₁ required until stop Thus, since the rotating body drive motor is controlled, the durability of the rotating body drive motor 55 can be improved.

  Then, as shown by the solid line in FIG. 9A, when the game ball 27 enters the second receiving portion 76 when the ball path sorting means 25 is rotating counterclockwise (counterclockwise) when viewed from the front, Since the inner peripheral surface 31 below the step portion 32 is slightly inclined rearward, the game ball 27 rotates together with the ball path distribution means 25 without falling forward, and the ball is discharged at the lowermost end. After falling into the groove 33, the game area 3 is discharged. Thereafter, the game ball 27 discharged from the ball discharge groove 33 wins the start winning opening 10 with a very high probability because the ball discharge groove 33 is located immediately above the start winning opening 10. As described above, the game balls 27 distributed to the left side pass through a specific path that is easy to win the start winning opening 10 when entering the second ball receiving portion 76 when the ball path distributing means 25 rotates in the reverse direction. To do.

  Further, as shown by the solid line in FIG. 9B, when the game ball 27 enters the second receiving portion 76 when the ball path distributing means 25 is rotating forward in the clockwise direction (clockwise), The movement of the game ball 27 is constrained by the step portion 32, is sandwiched between the step portion 32 and the side wall 78 of the first ball receiving portion 74, and is pushed out to the front game area 3. Then, the game ball 27 wins the start winning opening 10 with a lower probability than when passing through the specific route. As described above, when the game ball 27 enters the second ball receiving portion 76 while the ball route sorting means 25 is rotating forward, the game ball 27 passes through the general route that is difficult to win the start winning opening 10 from the specific route.

  Further, as shown by the solid line in FIGS. 10A and 10B, when the game ball 27 enters the first receiving portion 74 while the ball path sorting means 25 is rotating in the reverse direction, the game ball 27 is Since the front cover is prevented from falling forward by the left cover part 110, it rotates together with the ball path sorting means 25, falls forward near the lowermost end without the left cover part 110, and is discharged to the game area 3. In this case, since the fall position of the game ball 27 is located almost immediately above the start winning opening 10, the winning winning opening 10 is won with a very high probability. In this way, the game balls 27 distributed to the left side pass through a specific path that is easy to win the start winning opening 10 when entering the first ball receiving portion 74 when the ball path distributing means 25 is rotating forward. To do.

  Further, when the game ball 27 enters the first receiving portion 74 while the ball path sorting means 25 is rotating forward, the left side cover portion 110 prevents the game ball 27 from falling forward. It rotates together with the route distribution means 25, falls forward at a position where the left cover portion 110 is not present, and is discharged to the game area 3. In this case, since the fall position of the game ball 27 is on the upper left side of the start winning opening 10, the winning winning opening 10 is won with a lower probability than when passing through the specific route. As described above, when the game ball 27 enters the first ball receiving portion 74 while the ball route sorting means 25 is rotating forward, the game ball 27 passes through the general route that is difficult to win the start winning opening 10 from the specific route.

  On the other hand, when the game ball 27 enters the ball introduction hole 98 on the right side of the front, for example, the game ball 27 passes through the right distribution channel 106 from the ball inlet 104 and distributes to the right ball path distribution means 25 from the ball outlet 108. And enters the first sphere receiving portion 74 or the second sphere receiving portion 76.

  Then, as shown by a two-dot chain line in FIG. 9A, when the game ball 27 enters the second receiving portion 76 while the ball path distributing means 25 is rotating forward, the inner circumference below the step portion 32 is obtained. Since the surface 31 is slightly inclined toward the rear, the game ball 27 rotates together with the ball path distribution means 25 without falling forward, and after falling into the ball discharge groove 33 at the lowermost end, the game 31 It is discharged into area 3. Thereafter, the game ball 27 discharged from the ball discharge groove 33 wins the start winning opening 10 with a very high probability because the ball discharge groove 33 is located immediately above the start winning opening 10. As described above, the game balls 27 distributed to the right side pass through a specific path that is easy to win the start winning opening 10 when the ball path distributing means 25 enters the second ball receiving unit 76 while rotating forward. To do.

  Further, as shown by a two-dot chain line in FIG. 9B, when the game ball 27 enters the second receiving portion 76 while the ball path sorting means 25 is rotating in the reverse direction, the game ball 27 is moved to the step portion 32. The movement is restrained by this, and it is sandwiched between the stepped portion 32 and the side wall 78 of the first ball receiving portion 74 and pushed out to the game area 3 ahead. Then, the game ball 27 wins the start winning opening 10 with a lower probability than when passing through the specific route. As described above, when the game ball 27 enters the second ball receiving portion 76 while the ball route sorting means 25 is rotating in the reverse direction, the game ball 27 passes through a general route that is difficult to win the start winning opening 10 from the specific route.

  Further, as indicated by a two-dot chain line in FIGS. 10A and 10B, the game ball 27 is moved to the first receiving portion 74 when the ball path distributing means 25 is rotating forward clockwise (clockwise). When the ball enters the ball, the game ball 27 is prevented from falling forward by the right cover portion 111, and therefore rotates together with the ball path distributing means 25, and falls forward in the vicinity of the lowermost end without the right cover portion 111, The game area 3 is discharged. In this case, since the falling position of the game ball 27 is located immediately above the start winning opening 10, the winning winning opening 10 is won with a very high probability. In this way, the game balls 27 distributed to the left side pass through a specific path that is easy to win the start winning opening 10 when entering the first ball receiving portion 74 when the ball path distributing means 25 is rotating forward. To do.

  Further, if the game ball 27 enters the first receiving portion 74 while the ball path sorting means 25 is rotating in the reverse direction, the game ball 27 is prevented from falling forward by the right cover portion 111, so that the ball It rotates together with the route distribution means 25, falls forward at a position without the right cover portion 111, and is discharged to the game area 3. In this case, since the fall position of the game ball 27 is located on the upper right side of the start winning opening 10, the winning winning opening 10 is won with a lower probability than when passing through the specific route. Thus, when the ball 27 enters the first ball receiving portion 74 while the ball path sorting means 25 is rotating in the reverse direction, the game ball 27 passes through the general path that is difficult to win the start winning opening 10 from the specific path.

  As described above, since the game ball 27 guided to the stage portion 84 is formed with the ball guide protrusion 99, the ball guide path 100, and the ball fall prevention wall 101 on the stage portion 84, the center ball surely rolls. Since the center rolling surface 96 has a left-right symmetrical shape and the ball introduction holes 97 and 98 have the same diameter, the game ball 27 is evenly distributed to the left and right ball path distribution means 25. It is distributed to. Further, the left cover part 110 and the right cover part 111 are formed, and the inner peripheral surface 31 below the step part 32 is slightly inclined rearward, so that the first sphere receiving part 74 and the second sphere The game balls 27 that have entered the receiving portion 76 are reliably distributed to either the specific flow path or the general flow path according to the control of the rotating body 52 by the accessory (game part) control means 29. Therefore, even if the installation angle of the pachinko gaming machine on the game island varies, the ratio of entering the specific flow path and the general flow path does not change, the nail is easy to adjust, and the exit rate is Adjustment is easy.

  In addition, the game ball 27 that has been bulleted may fall directly onto the stage portion 84, but even in this case, the specific flow path and the general flow are the same as when the ball passes through the ball flow paths 53 and 54. Evenly distributed to the road.

  In this way, the game ball 27 passes from the ball guiding means 28 through the ball passages 53 and 54, through the specific passage or the general passage, or without passing through the ball passages 53 and 54. When the winning means 10 wins the start winning opening 10 through the specific flow path or the general flow path from the guiding means 28, the start winning detector 12 detects the winning of the game ball 27 to the start winning opening 10, and the detection signal is It is sent to the game control device 20. And the game control apparatus 20 transmits a symbol start signal based on this detection signal, and the symbol display on the symbol display device 16 is started by this symbol start signal. At this time, every time the start winning detector 12 detects winning of the game ball 27 to the start winning opening 10, the symbol is changed and stopped once, but the game ball 27 is displayed during the change display of the symbol. When the winning prize detector 12 detects a winning at the starting prize opening 10, a holding lamp (not shown) is turned on to notify the player of that. The number of game balls 27 detected by the start winning detector 12 during the symbol variation display is stored up to a maximum of four, and as soon as the variation / stop operation of the symbol is completed, the number of times corresponding to the number of holding lamps. The symbols are changed and stopped sequentially.

  As described above, when the symbol display is started on the symbol display device 16 and a predetermined time has elapsed, the game control device 20 determines that the symbols of the left symbol 5 and the right symbol 7 are aligned, for example, the game is reached. Inform the player that he is in a state, and make the player have a sense of expectation.

  After that, when the game control device 20 determines that all the symbols of the left symbol 5, the middle symbol 6, and the right symbol 7 are ready, the game control device 20 notifies that the game is in the big hit state, and from the normal game to the special game (hit game) Migrate to

  When entering the special game in this way, the big prize opening 11 is opened, and when the game ball 27 wins the big prize opening 11, 15 prize balls are paid out to the player. The grand prize opening 11 is temporarily closed when either 30 seconds have elapsed since the opening or when there is a 10-ball prize, but the grand prize opening 11 is open. When there is a winning in the specific area (V zone), the special winning opening 11 is opened again. The special winning opening 11 can be continuously opened up to 16 times. The special winning opening 11 has been opened 16 times or the special area (V If the specific area passage detector 13 does not detect a prize in the zone), the special game ends.

  In the first embodiment, the case where one first slit hole 65 is provided in the first sensor detection piece 64 has been described. However, two first slit holes 65 may be provided. In this case, as shown in FIG. 13, the direction switching control unit 113 of the rotating body control unit 11 decelerates the rotating body drive motor 55 based on the detection signal of the first first slit hole 65 from the first photosensor 58. In response to the detection signal from the second first slit hole 65, the rotating body drive motor 55 is stopped. Then, when the rotating body drive motor 55 stops and a predetermined time, for example, t seconds elapses, the direction switching control means 113 starts and rotates the rotating body drive motor 55 in the opposite direction, thereby rotating the rotating body 52 at a predetermined speed. Reverse rotation. In this case, the direction switching control means 113 ignores the detection signal of the first slit hole 65 from the first photosensor 58 immediately after the rotation direction of the rotating body 52 is switched twice.

As a result, as in the case of a single first slit hole 65, the rotating direction of the rotating body 52 can be switched between the forward and reverse directions each time the rotating body 52 rotates once, and the rotating body drive motor 55 can be switched. Rotating body drive motor 55 can be controlled such that time t ₁ required for rotating body drive motor 55 to decelerate and stop is longer than time t ₂ required for the motor to reach a predetermined speed after starting. . In this case, since the two first slit holes 65 are provided, the rotation drive motor 55 of the rotation body drive motor 55 can be controlled with higher accuracy.

  In the first embodiment, the second photosensor 59 is not used. However, the second photosensor 59 detects the second slit hole 68 of the second sensor detection piece 67, and the rotating body 52. Can also be controlled. In this case, since the second sensor detection pieces 67 are formed with twelve second slit holes 68 at a central angle of 30 °, for example, the sixth second slit hole 68 (ie, 180 ° at the time of forward rotation). Only the second slit hole 68 after rotation is detected, and only the twelfth second slit hole 68 (that is, the second slit hole 68 after 360 ° rotation) is detected during reverse rotation. By changing the detection pitch of the second slit holes 68 of the second photosensor 59 in the case of reverse rotation, not only the rotating body 52 is rotated alternately at the same angle but also various rotation controls of the rotating body 52. The distribution ratio of the game balls 27 to the specific route and the general route can be changed variously to a desired ratio.

  Further, the diameter (for example, 14 mm) of the left sphere introduction hole 97 of the central rolling surface 96 of the stage portion 84 is made larger than the diameter (for example, 12 mm) of the right sphere introduction hole 98, as shown in FIG. If the condition achievement determination means 114 is provided in the accessory (game part) control means 29 of the game control device 20 and the condition achievement determination means 114 determines that the predetermined condition is satisfied, the rotating body 52 is rotated forward. The normal state, which is disadvantageous for a player whose speed is lower than the reverse rotation speed, may be shifted to a special state which is advantageous for a player whose forward rotation speed of the rotating body 52 is higher than the reverse rotation speed. Thus, by creating a normal state that is disadvantageous for the player and a special state that is advantageous for the player, it is possible to provide the player with a new interest and improve the gameability. it can.

  More specifically, as shown in FIG. 15 (a), a special symbol stop mode determination unit 115 is provided in the condition achievement determination unit 114, and a specific symbol in which the symbol of the display unit 4 of the symbol display device 16 is set in advance. For example, when “331” is reached, the normal state is shifted to the special state, or, as shown in FIG. The storage means 117 and the winning rate calculation means 118 are provided, and the winning prize amount storage means 117 stores the number of winnings to the start winning mouth 10 per unit time measured by the unit time counting means 116 and the stored winnings are also stored. Based on the number, the winning rate calculating means 118 calculates the winning rate, and when the winning rate is higher or lower than a predetermined rate, the normal state is shifted to the special state, or 15 (c), the condition achievement determination means 114 is provided with a unit time counting means 116, a special game number storage means 119, and a special game number comparison means 120 per unit time. When the number of special games per time is stored in the special game number storage means 119 and the special game number comparison means 120 determines that the stored special game number is higher or lower than a predetermined number, As shown in FIG. 15D, the condition achievement determination unit 114 is provided with a unit time counting unit 116, a probability variation number storage unit 121, and a probability variation number comparison unit 122 per unit time. The number of special games per unit time measured by the unit time counting unit 116 is stored in the established variation number storage unit 121. It was, in the case where the stored probability variation time count is determined a predetermined high or low and per unit time probability change count comparing means than the number 122 may be or is switched from the normal state to the special state. Furthermore, it may be configured to shift from the normal state to the special state under conditions other than the above-described conditions.

  In this case, as shown in FIG. 14, the game control device 20 is provided with a symbol control means 123 and a special game determination execution means 124 in addition to an accessory (game part) control means 29. The means 123 is provided with a symbol variation storing means 125 and a stop symbol determining means 126. The special game determination executing means 124 is provided with a special game transition determining means 128 having a special area passage determining means 127 and a special prize opening opening / closing drive. Special game execution means 130 provided with control means 129 is provided.

  In this case, the right and left ball introduction holes 97 and 98 have the same diameter, and the inclination of the stage portion 84 is changed so that the introduction rate of the game ball 27 with respect to the ball introduction holes 97 and 98 is different on the left and right. May be.

  As described above, according to the present invention, a specific condition similar to a specific game state such as a probability change or a short-time mode can be created by achieving a predetermined condition in the normal game state. Even if the game is continued for a long time, the player's interest can be strongly attracted to the pachinko game and can be interesting. In addition, it is possible to adjust the winning rate for a specific winning opening without adjusting the nail, and the work can be simplified.

  Next, a decorative body according to a second embodiment of the present invention will be described with reference to FIGS. 16 and 17.
