When the pachinko ball 21 enters at least one of the ball inlets 27 and 28, the pachinko ball 21 flows down the guide passage 34 and is discharged from the ball outlet 33 toward the start winning opening 13. Accordingly, the pachinko ball 21 that has entered the ball entrances 27 and 28 has a higher probability of winning the start winning opening 13. The high probability winning route is composed of ball inlets 27 and 28, a ball outlet 33, and a guide passage 34.

  A rotating body 35 that rotates freely is provided on the convex portions 23 a and 24 a at the center of the first and second rolling surfaces 23 and 24. Free rotation means that the pachinko ball 21 is rotatable by colliding with the rotating body 35.

  Next, the configuration of the rotating body 35 will be described. In addition, since the structure of the rotary body 35 provided in the 1st and 2nd rolling surfaces 23 and 24 is the same, it demonstrates taking the case of the rotary body 35 provided in the 2nd rolling surface 24 as an example. As shown in FIGS. 4 and 5, the rotator 35 includes a wing portion 36, a shaft portion 37, and a main gear 38. One end of the shaft portion 37 protrudes above the second rolling surface 24 and is provided with a wing portion 36 on which the pachinko ball 21 rolling on the second rolling surface 24 collides. The other end of the shaft portion 37 is disposed inside the stage 20, and a main gear 38 for transmitting rotational driving from a stepping motor 50 described later to the shaft portion 37 is provided.

  On the lower surface of the main gear 38, a detection piece 40 for detecting that the rotating body 35 is at the guide position is provided. The guide position is a position where the pachinko ball 21 rolling on the second rolling surface 24 is guided to the ball inlet 28 by the receiving surface 41 provided on the wing portion 36. The guide position on the rotating body 35 provided on the first rolling surface 23 is a position where the pachinko ball 21 rolling on the first rolling surface 23 is guided to the ball inlet 27 by the receiving surface 41.

  A position detection sensor 43 serving as a rotation position detection unit is provided on the rotation path of the detection piece 40 that rotates with the free rotation of the rotator 35. A photo sensor is used as the position detection sensor 43, and when the rotating body 35 stops at the guide position, the position detection sensor 43 detects the detection piece 40. In the present embodiment, one detection piece 40 is provided on the main gear 38, but the pachinko ball 21 may be guided to the ball inlet 28 by the other two receiving surfaces 41 provided on the wing portion 36. In this case, it is preferable to provide a total of three detection pieces 40 corresponding to the guide positions.

  Further, an encoder 45 serving as a measuring unit is provided below the main gear 38. The encoder 45 is composed of an encoding plate 47 fixed to the shaft portion 37 and having a large number of slits 46 formed radially at a constant pitch, and a slit sensor 48 which is a photosensor for monitoring the passage of the slits 46. That is, every time the encode plate 47 rotates by a certain angle, one pulse signal (hereinafter referred to as slit detection pulse) is output from the slit sensor 48, and the rotation amount of the rotating body 35 is measured by counting the slit detection pulses. To do.

  Further, a stepping motor 50 as a driving means and a solenoid 51 as a switching mechanism are provided inside the stage 20 and in the vicinity of the main gear 38 of the rotating body 35. The stepping motor 50 is driven and controlled by the main CPU 63 (see FIG. 6) via the motor driver 76. The drive shaft 52 of the stepping motor 50 is provided with a drive gear 53 for transmitting rotational driving to the rotating body 35.

  The operation of the solenoid 51 is controlled by a main CPU 63 (see FIG. 6) described later. The drive iron core 54 of the solenoid 51 is provided with a connecting gear 55 that fits with the main gear 38 and the drive gear 53. When energization of the solenoid 51 is started, a magnetic field is generated by a coil (not shown) wound in the bobbin 56, and the driving iron core 54 is drawn into the bobbin 56. When the energization of the solenoid 51 is stopped, the driving iron core 54 drawn into the bobbin 56 protrudes from the bobbin 56 by the restoring force of the spring in the bobbin 56. Therefore, the driving iron core 54 is pulled into the bobbin 56 when the solenoid 51 is energized on and off (see FIG. 5A), and the protruding position protruding from the bobbin 56 (FIGS. 5B and 5C). Browse). When the driving iron core 54 is in the protruding position, the coupling gear 55 is engaged with the main gear 38 and the driving gear 53, so that the rotation driving state in which the rotation driving of the stepping motor 50 is transmitted to the rotating body 35 is established. Further, in the retracted position, the connecting gear 55 is not fitted with the main gear 38 and the drive gear 53, so that the rotating body 35 is in a free rotating state in which it rotates freely.

  During the game, as shown in FIG. 5A, the driving iron core 54 is in the retracted position, and the rotating body 35 is in a free rotating state. When a predetermined condition is satisfied during the game, the driving iron core 54 moves from the retracted position to the protruding position shown in FIG. 5B, and the connecting gear 55 is engaged with the main gear 38 and the driving gear 53 to enter the rotational driving state. Become. And the rotation drive of the stepping motor 50 is transmitted by each gear, and the rotary body 35 is rotationally driven. And if the detection piece 40 is detected by the position detection sensor 43, as shown in FIG.5 (C), the rotational drive of the stepping motor 50 will be stopped. At this time, as a feature of the stepping motor 50, the position of the drive shaft 52 is maintained with a high holding torque when stopped, so that the rotating body 35 is held at the guide position even if the pachinko ball 21 collides with the rotating body 35. Note that the holding means includes a stepping motor 50, a solenoid 51, and a position detection sensor 43.

  FIG. 6 is a block diagram showing an electrical configuration of the pachinko machine 2. As shown in FIG. 6, the operation of the pachinko machine 2 is basically controlled by the main control circuit device 60 and the sub control circuit device 61.

  The main control circuit device 60 includes a main CPU 63 (central processing unit), a main ROM 64 (read only memory), and a main RAM 65 (random access memory). The main CPU 63 reads a game control program stored in the main ROM 64 to generate a command for controlling the gaming state of the pachinko machine 2, and transmits command information to the sub-control circuit device 61 to enter a predetermined gaming state. To make it run. In the main ROM 64, a game control program, a random number generation processing program, a random number table, and the like are stored in predetermined areas, and these are read out by the main CPU 63 and used appropriately so as to be processed. The main RAM 65 is a working area and is used for temporary storage or rewriting of data used in the game.

  The sub control circuit device 61 includes a sub CPU 66, a sub ROM 67 and a sub RAM 68. The sub CPU 66 appropriately reads out the sub control program stored in the sub ROM 67, and provides it in the symbol display device 12 and the pachinko machine 2 according to the sub control program according to the control signal input as command information from the main control circuit device 60. A control signal is output to the generated sound generator 70 to control the driving of each driving device. The sub-RAM 67 serves as a working area, and is used for temporary storage or rewriting of data used in the control of the symbol display device 12 and the sound generator 70. Note that the device whose driving is controlled by the sub CPU 66 is not limited to the symbol display device 12 and the sound generation device 70, and includes a movable winning device provided in the game area 11.

  When the signal from the winning ball detection sensor 71 is input, the main CPU 63 drives the ball payout device 72 on the supply tray 5 based on the game control program stored in the main ROM 64. Pay out. The number of prize balls may be set as appropriate according to the type of each prize-winning port 13-15 containing the pachinko balls 21. Further, the main CPU 63 monitors the gaming state, and when an error occurs, the main CPU 63 stops the firing of the pachinko ball 21 even if the firing handle 4 is operated.

  The slit sensor 48 is controlled by the main CPU 63. One slit detection pulse is output by the slit sensor 48 every time the rotator 35 rotates by a certain angle by free rotation. This slit detection pulse is input to the counter 75 via the main CPU 63. The counter 75 counts slit detection pulses.

  The start and stop of energization of the solenoid 51 is controlled by the main CPU 63. As the pachinko machine 2 is turned on, the main CPU 63 starts energizing the solenoid 51. The main CPU 63 confirms the count value of the counter 75 in real time. When the count value of the counter 75 is counted up to a predetermined value set in advance, the main CPU 63 resets the counter 75 and returns to the solenoid 51. Is turned off for a certain period of time. As a result, the drive iron core 54 moves from the retracted position to the protruding position for a certain time. In addition, after energization to the solenoid 51 is stopped for a certain time, the energization to the solenoid 51 is started again.

  The stepping motor 50 is driven and controlled by the main CPU 63 via the motor driver 76. When the energization of the solenoid 51 is stopped, the main CPU 63 outputs a drive signal to the motor driver 76 in order to drive the stepping motor 50 to rotate. Based on this drive signal, the motor driver 76 controls the rotation speed and rotation direction of the stepping motor 50 to drive the stepping motor 50 to rotate. Further, when a stop signal is output from the main CPU 63 to the motor driver 76, the motor driver 76 stops the rotation driving of the stepping motor 50.

  The position detection sensor 43 detects the detection piece 40 provided on the rotating body 35. When the detection piece 40 is detected by the position detection sensor 43 as the rotator 35 rotates, a detection signal from the position detection sensor 43 is output to the main CPU 63. The main CPU 63 invalidates the detection signal input when the solenoid 51 is energized, and validates the detection signal input when the solenoid 51 is de-energized. When a detection signal is input to the main CPU 63 in the enabled state, a stop signal is output to the motor driver 76. The motor driver 76 stops the stepping motor 50 based on this stop signal.

  Next, the operation of the pachinko machine 2 configured as described above will be described with reference to the flowchart of FIG. The pachinko ball 21 launched by the rotation operation of the firing handle 4 rolls while temporarily staying on the first and second rolling surfaces 23 and 24 of the stage 20, or is played while being played by a nail or a windmill. The area flows down and either the start winning port 13, the normal winning port 14, the passing winning port 15 is won, or the out port 17 is entered.

  The player searches for a point where many pachinko balls 21 flowing down the game area 11 stay on the stage 20, and strikes the pachinko ball 21 at that point while finely adjusting the rotation operation of the firing handle 4. As shown in FIG. 8A, a plurality of pachinko balls 21 randomly enter the first and second rolling surfaces 23, 24 of the stage 20 from the left-right direction. Among the pachinko balls 21 that enter, the pachinko balls 21 that roll laterally along the unevenness of the first and second rolling surfaces 23 and 24, and the first or second rolling surfaces 23 and 24 slightly roll. Some move and fall from the stage 20.

  When the pachinko balls 21 that have entered the first and second rolling surfaces 23 and 24 collide with the rotating body 35, the rotating body 35 performs free rotation due to the collision of the pachinko balls 21 as shown in FIG. Thereby, since the advancing direction of the pachinko sphere 21 rolling on the first and second rolling surfaces 23 and 24 is changed by the rotating body 35, the movement of the pachinko sphere 21 is changed. Further, when the momentum of the pachinko ball 21 rolling on the first and second rolling surfaces 23 and 24 is weak, the pachinko ball 21 is bounced by the rotating body 35 and falls from the stage 20. Thereby, it is possible to prevent the movement of the pachinko ball 21 from stopping on the stage 20.

  The amount of rotation of the rotating body 35 that rotates freely is measured by the encoder 45. As a predetermined condition satisfied during the game, the main CPU 63 stops energization of the solenoid 45 when the rotation amount of the rotating body 35 measured by the encoder 45 becomes a predetermined rotation amount. As a result, the driving iron core 54 moves from the retracted position shown in FIG. 5A to the protruding position shown in FIG. 5B, and the connecting gear 55 is engaged with the driving gear 53 and the main gear 38. The rotating body 35 is rotated by the stepping motor 50 being driven to rotate. At this time, as shown in FIG. 5C, when the detection piece 40 is detected by the position detection sensor 43, the rotation drive of the stepping motor 50 is stopped for a certain period of time because the rotating body 35 is at the guide position, The body 35 is held at the guide position.

  When the rotator 35 is held at the guide position, the pachinko balls 21 rolling from the left in the drawing on the first rolling surface 23 are received by the rotator 35 as shown in FIG. The pachinko ball 21 colliding with the surface 41 is guided to the ball inlet 27 by the receiving surface 41. Further, on the second rolling surface 24, the pachinko ball 21 rolling from the right in the figure collides with the receiving surface 41 of the rotating body 35, and the pachinko ball 21 collided by the receiving surface 41 is guided to the ball entrance 28. Is done. As a result, the pachinko ball 21 that has entered from the ball inlets 27 and 28 is guided to the guide passage 34 provided in the stage 20 and travels from the ball outlet 33 toward the start winning opening 13 as shown in FIG. 9B. Are sequentially discharged. Thereby, since the probability that the pachinko ball 21 wins the start winning opening 13 is increased, a lot of winning lotteries are performed, and the player is expected to win, so the player's interest can be enhanced.

  Then, when the stepping motor 50 holds the rotating body 35 and a predetermined time elapses, the energization of the solenoid 51 is started again. As a result, the drive iron core 54 moves from the protruding position shown in FIG. 5C to the retracted position shown in FIG. 5A, so that the rotating body 35 performs free rotation again by the collision of the pachinko balls 21. Accordingly, a number of pachinko balls 21 are placed at the start winning opening 13 by a technical intervention such as a player adjusting the launch point and launch timing of the pachinko balls 21 so that many pachinko balls 21 roll on the stage 20. It is possible to win a prize and enhance the interest of the player.

  Further, in the above embodiment, the driving iron is used as a switching mechanism that switches between the rotational driving state in which the rotational driving of the stepping motor 50 is transmitted to the rotating body 335 and the free rotating state in which the rotational driving is freely transmitted without transmitting the rotational driving to the rotating body 35. Although the solenoid 51 provided with the connecting gear 55 is used for the core 54, a switching motor for changing the direction of the stepping motor 50 may be used instead, as shown in FIG. In this case, the rotation drive state and the free rotation state are switched by changing the direction of the stepping motor 50. In addition, the same code | symbol is attached | subjected to the same component as the said embodiment, and description is abbreviate | omitted.

  As shown in FIG. 9, the switching mechanism includes a turntable 80 on which the stepping motor 50 is installed, and a switching motor 81 that rotates the turntable 80. The switching motor 81 is preferably a stepping motor or a geared motor. The switching motor 81 is fixed to a base (not shown) provided inside the stage 20 with the drive shaft 82 facing upward. A drive shaft 82 of a switching motor 81 is fixed to the lower surface of the turntable 80, and an arc portion 85 into which the stepping motor 50 is fitted is formed on the upper surface.

  A worm 86 is provided on the drive shaft 52 of the stepping motor 50, and a worm wheel 87 that fits the worm 86 is provided on the shaft portion 37 of the rotating body 35. The worm 86 and the worm wheel 87 constitute a worm gear.

  The stepping motor 50 has a retracted position (see FIG. 9A) where the worm 86 is not fitted to the worm wheel 87 and a connecting position where the worm 86 is fitted to the worm wheel 87 (FIG. 9). (See (B)). Thereby, when the stepping motor 50 is in the retracted position, the rotating body 35 is in a free rotating state, and when in the connected position, it is in a rotationally driven state.

  Normally, the stepping motor 50 is in the retracted position at the start of the game. Therefore, the rotating body 35 in the free rotating state changes the traveling direction of the pachinko balls 21 that roll on the first and second rolling surfaces 23 and 24. When the rotation amount of the rotating body 35 measured by the encoder 45 reaches a predetermined rotation amount, the main CPU 63 drives and controls the switching motor 81 to change the stepping motor 50 from the retracted position to the connected position. As a result, the rotating body 35 enters a rotational drive state, and the stepping motor 50 is rotationally driven. And if the detection piece 40 is detected by the position detection sensor 43, the rotational drive of the stepping motor 50 will be stopped and the rotary body 35 will be hold | maintained in a guide position. As a result, the pachinko ball 21 is guided to the ball entrances 27 and 28, and the pachinko ball 21 wins the start winning opening 13, whereby a lot of winning lotteries are performed. Therefore, technical intervention such as launching a large number of pachinko balls 21 on the stage 20 becomes possible, and it is possible to enhance the interest of the player.

  In the above embodiment, as a predetermined condition when the rotating body 35 is held at the guide position, the rotation amount of the rotating body 35 is measured by the encoder 45, and the measured rotation amount becomes a predetermined rotation amount. The rotating body 35 is held at the guide position. However, the present invention is not limited to this. When the measurement result obtained by measuring the rotation speed of the rotating body 35 or the big win by the winning lottery is determined, the normal winning opening 14 or the passing winning opening 15 is won. It is preferable to set the predetermined conditions as appropriate.
