Description

  The present invention relates to a gaming machine such as a pachinko machine that is installed and used in a game hall such as a pachinko parlor.

Currently, pachinko machines installed in amusement halls are provided with an operation handle on the front surface (see Patent Document 1). The operation handle is provided with a ring holder that can be rotated. When the ring holder is rotated, the rotation is transmitted to the ball launcher via the transmission unit, and the pachinko ball is played by the ball launcher. Launched into the area. When playing a game, the player turns the ring holder by a predetermined amount so as to twist with one hand using the wrist, and hits a pachinko ball into the game area. This ring holder has a pachinko ball launch strength that changes in proportion to the amount of rotation. For this reason, the player adjusts the amount of rotation of the ring holder so as to achieve the intended launch strength.
JP 2004-329730 A

  However, in the case of this operation handle, since the ring holder is rotated so as to be twisted with one hand using the wrist, a burden is placed on the wrist and fingers of the player. Further, the ring holder is biased by a spring in a direction to return to the reference position where the pachinko ball is not launched. For this reason, in order to maintain the intended launch strength, holding the rotated ring holder at a fixed position against the biasing force of the spring is particularly handy for a player who plays a game for a long time. Will be burdensome. In this case, for example, it is conceivable that the game is resumed once the hand is released from the ring holder, but once the ring holder is released, the ring holder is in a state where the pachinko ball is not launched by the ball launcher. Therefore, it was necessary to adjust the launch strength by rotating the ring holder again, and the operability during the game was poor.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine that can reduce the burden on the player's hand during the game and improve the operability. .

  As shown in FIG. 8A, in a normal state (a state where the main body 34a of the solenoid 34 is not energized), the fixed plate 32 and the driving iron core 34b of the solenoid 34 are separated from each other. When the main body 34a of the solenoid 34 is energized, the energized main body 34a moves the driving iron core 34b in the direction C in FIG. 8, as shown in FIG. 8B. The moved driving iron core 34b comes into contact with a fixing plate 32 attached to the rear surface of the grip body 27a, and the grip 27 is fixed to be non-rotatable by the contact resistance. In the present embodiment, the position fixing means for fixing the grip 27 at the rotated position includes the fixing plate 32 and the solenoid 34.

  A lock switch 35 is provided on the upper surface of the grip body 27a, and this lock switch 35 is connected to a lock circuit 44 (see FIG. 9) in the main control board 15. The lock switch 35 is provided at a position where it can be operated by the index finger when the middle finger, the ring finger, and the little finger are inserted into the insertion hole 27c and the thumb is placed on the finger hook portion 27d (see FIG. 4). When the player presses the lock switch 35, a rotation lock signal is input from the lock switch 35 to the lock circuit 44.

  As shown in FIGS. 6 and 7, a hammering strength adjusting volume 36 is provided inside the front frame 5. The punching strength adjusting volume 36 includes a plate-like base 36a and a columnar shaft 36b, and the shaft 36b is rotatably provided on the base 36a. The shaft 36b is formed in a circular shape on the base side, changes in shape at a substantially central portion, and is formed in a substantially D-shape on the tip side. An adjustment gear 37 is inserted into the shaft 36b. The striking strength adjusting volume 36 is provided at a position where the adjusting gear 37 meshes with the grip gear 27e of the grip 27, and the shaft 36b is rotated by the rotation of the grip 27.

  The adjustment gear 37 is formed with a concave insertion concave portion 37a for inserting the shaft 36b. The insertion concave portion 37a serves as a rotation center when the adjustment gear 37 is rotated. The insertion concave portion 37a is formed in a circular shape on the inlet side, changes in shape at a substantially central portion, and is formed in a substantially D shape on the bottom surface side. When the insertion recess 37a of the adjustment gear 37 is inserted into the shaft 36b of the punching strength adjustment volume 36, the substantially D-shaped portions of the shaft 36b and the insertion recess 37a are aligned and inserted into the tip of the shaft 36b. By inserting the concave portion 37 a, the adjustment gear 37 and the launch strength adjustment volume 36 are positioned, and the adjustment gear 37 is fixed to the launch strength adjustment volume 36. The shaft 36b of the height adjusting volume 36 is rotated. The launch strength adjusting volume 36 is connected to a rotation amount calculation unit 41 (see FIG. 9) in the main control board 15.

  When the first arm portion 39b is brought into contact with the left side surface of the spring locking convex portion 27f in FIG. 6 and the second arm portion 39c is rotated in the B direction in FIG. 6, the first arm portion 39b is moved in the B direction in FIG. The second arm portion 39c generates a rotational force that tries to rotate in the direction A in FIG. Then, when the second arm portion 39c is brought into contact with the left side surface of the spring locking portion 26c in FIG. 6, the first arm portion 39b becomes the spring locking convex portion 27f and the second arm portion 39c becomes the spring locking portion 26c. And the torsion spring 39 is fixed. As a result, the grip 27 is biased toward the reference position by the torsion spring 39 (rotates in the B direction in FIGS. 6 and 7).

  As shown in FIG. 9, the operation of the pachinko machine 2 is basically controlled by the main control board 15 and the sub control board 16.

  The main control board 15 includes a main CPU (central processing unit) 15a, a main ROM (read only memory) 15b, a main RAM (random access memory) 15c, a rotation amount calculation unit 41, a firing circuit 42, a contact detection processing unit 43, a lock The circuit 44 is configured. The main CPU 15a reads a game control program stored in the main ROM 15b in accordance with an input signal input from the winning ball detection sensor 14, generates a command for controlling the gaming state of the pachinko machine, and also generates a sub-control board 16 The command information is transmitted to and executed in a predetermined gaming state. In the main ROM 15b, 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 15a and appropriately used so as to be processed. The main RAM 15c is a working area and is used for temporary storage or rewriting of data used in the game.

  The sub control board 16 includes a sub CPU 16a, a sub ROM 16b, and a sub RAM 16c. The sub CPU 16a appropriately reads out the control program for the sub control device stored in the sub ROM 16b, and in accordance with the control signal input as command information from the main control board 15, the sub control board 16 and the design A drive signal is input / output to / from the variable display device 9, the sound generation device 21, and the lamp 22 to perform a predetermined gaming state. The sub RAM 16c serves as a working area, and is used for temporary storage or rewriting of data used in the control of the symbol variable display device 9, the sound generator 21, and the lamp 22. The device for controlling the driving by the sub CPU 16a is not limited to the symbol variable display device 9, the sound generating device 21, and the lamp 22, and includes a movable winning device provided in the game area 4a.

  When the signal from the winning ball detection sensor 14 is input, the main CPU 15a drives the ball payout device 18 based on the game control program stored in the main ROM 15b to supply a predetermined number of winning balls on the supply tray 6 Pay out. Note that the number of winning balls may be set as appropriate according to the type of each of the winning holes 10 to 12 containing gaming balls.

  The operation of the pachinko machine configured as described above will be described. The player inserts the index finger, middle finger, ring finger, and little finger into the insertion hole 27c, hangs the thumb on the finger-hanging portion 27d, and rotates the grip 27 in a state where the palm is in contact with the rubber pad 30, so that the ball launching device 17, the pachinko ball 7 is launched into the game area 4a. At this time, the player can easily rotate the grip 27 against the urging force of the torsion spring 39 only by applying a force to the little finger side.

  When the grip 27 is rotated, the shaft 36 b of the launch strength adjusting volume 36 is rotated via the grip 27 and the adjusting gear 37. The striking strength adjusting volume 36 sends a rotation amount signal corresponding to the rotation amount of the shaft 36 b to the rotation amount calculation unit 41. The rotation amount calculation unit 41 sends a corresponding voltage signal to the firing circuit 42 based on the received rotation amount signal. When the player touches the conductive grip 27, the contact detection processing unit 43 is energized through the contact detection plate 33 and a wire (not shown). Based on this energization, the contact detection processing unit 43 sends a firing permission signal to the firing circuit 42 and a lock permission signal to the lock circuit 54. The firing circuit 42 sends a corresponding drive signal to the main CPU 15a based on the voltage signal sent from the rotation amount calculation unit 51 and the launch permission signal sent from the contact detection processing unit 43. The main CPU 15 a drives the ball launching device 17 based on the received drive signal, and performs operation control for launching the pachinko ball 7 onto the game board 4 with a launch strength corresponding to the rotation amount of the grip 27.

  When the player presses the lock switch 35 in a state where the pachinko ball 7 has been launched on the surface of the game board 4, a rotation lock signal is sent to the lock circuit 44. The lock circuit 54 sends a lock drive signal to the main CPU 15a based on the lock permission signal sent from the contact detection processing unit 43 and the rotation lock signal sent from the lock switch 35. The main CPU 15a energizes the main body 34a of the solenoid 34 based on the received lock drive signal, and the energized main body 34a places the drive iron core 34b in FIG. 8C as shown in FIG. Move in the direction. The moved driving iron core 34b contacts the fixing plate 32 attached to the rear surface of the grip body 27a. The fixed plate 32 is made of rubber having a high friction coefficient, and the contact resistance generated when the driving iron core 34b comes into contact is larger than the urging force of the torsion spring 39 that urges the grip 27 in the direction to return to the reference position. Become. Thereby, the grip 27 is fixed so as not to rotate. When the player releases the lock switch 35, the main CPU 15a stops energization of the main body 34a, and the main body 34a that is deenergized moves the driving iron core 34b in the direction D in FIG. Thereby, the contact with the fixed plate 32 of the drive iron core 34b is released, and the fixation of the grip 27 is released.

  When the player presses the firing stop switch 31 while the pachinko ball 7 is being launched on the surface of the game board 4, a firing stop signal is sent to the launch circuit 42. The launch circuit 42 stops outputting the drive signal to the main CPU 15a in response to the launch stop signal being input. Thereby, the drive of the ball launcher 17 can be stopped while the grip 27 is rotated.

  As described above, when the player rotates the grip 27, the player is away from the center of the rotation shaft 27b when the grip 27 is positioned at the reference position (see FIG. 4A), and the rotation shaft 27b. Insert the index finger, middle finger, ring finger, and little finger into the insertion hole 27c formed above the center of the finger, hang the thumb on the finger rest 27d, and force the palm toward the little finger with the palm in contact with the rubber pad 30 The grip 27 can be easily rotated against the urging force of the torsion spring 39 simply by applying. The grip 27 is rotatable within a range of about 60 °, and the insertion hole 27c is the center of the rotation shaft 27b even when the grip 27 is rotated to the maximum rotation position (see FIG. 4B). Therefore, when the grip 27 is rotated to any position within the rotatable range, the grip 27 is easily rotated against the bias of the torsion spring 39 only by applying a force to the little finger side. be able to. Further, since the palm abuts against the rubber pad 30, it is possible to reduce the burden on the finger as compared with the case where the grip 27 is rotated only by the finger.

  Further, when the player presses the lock switch 35 during the game, the moved driving iron core 34b comes into contact with the rubber fixed plate 32 having a high coefficient of friction attached to the grip body 27a, and the grip 27 is pulled by the contact resistance. The lock switch 35 is pressed without requiring a force to maintain the position of the grip 27 against the biasing of the torsion spring 39 that biases the grip 27 in the direction to return the grip 27 to the reference position. Since the position of the grip 27 can be maintained only by this, the burden on the player's hand can be reduced.

  In the above embodiment, the driving iron core 34b of the solenoid 34 is brought into contact with the rubber fixing plate 32 having a high coefficient of friction, and the grip 27 is fixed to be non-rotatable by the contact resistance. However, the grip 27 cannot be rotated. However, the grip 27 is made non-rotatable by making the abutment member abut on the gear teeth of the grip gear 27e or the adjustment gear 37 and making them non-rotatable. In addition, a magnetic member made of a magnetic material may be attached to the grip body 27a, and the magnetic member may be held by magnetism generated from the magnetic portion so that the grip 27 is fixed to be non-rotatable. Well, it can be changed as appropriate.

  FIG. 10 shows another embodiment. Constituent members similar to those in the above embodiment are given the same reference numerals, and the detailed description thereof is simplified. As shown in FIG. 10, in this embodiment, an armrest (hand-mounted portion) 50 is attached to the front frame 5. The armrest 50 is formed in a shape such that a wrist that is a part of the player's hand (portion from the shoulder to the fingertip) fits comfortably. Accordingly, the player can perform the rotation operation of the grip 27 with the wrist placed on the armrest 50, so that the player can play the game with a more comfortable hand. Furthermore, since the burden on the hand can be reduced when the grip 27 is maintained at the rotated position, the fixing plate 32, the solenoid 34, and the lock switch 35 for fixing the grip 27 at the rotated position are provided. Can be removed.
