One small inner hole 77 has a range of 120 degrees in the rotation angle around the center of the damper shaft 17. One large inner hole 78 has a range of 60 degrees in the rotation angle around the center of the damper shaft 17. The rotor 76 includes a plurality of small arc-shaped convex portions 79 having a small curvature radius centered on the center of the damper shaft 17 and a plurality of large arc-shaped convex portions 80 having a large curvature radius centered on the damper shaft 17 in the circumferential direction.

  7, the large arc-shaped convex portion 80 of the rotor 76 is opposed to the large internal hole 78 of the stator 75 in the radial direction, and the small arc-shaped convex portion 79 of the rotor 76 is the small internal hole of the stator 75. When facing 77 in the radial direction, only the intermediate liquid chamber 83 is formed as a gap between the stator 75 and the rotor 76. In the case of FIG. 7a, the shock absorber 12 can generate a minimum torque. As shown in FIG. 7B, the small arc-shaped convex portion 79 of the rotor 76 has the large internal hole 78 of the stator 75 and a part of the small internal hole 77 of the stator 75 facing each other in the radial direction. A large liquid chamber 82 and an intermediate liquid chamber 83 are formed between the rotor 75 and the large arc-shaped convex portion 80 of the rotor 76 diametrically opposed to the remaining portion of the small inner hole 77 of the stator 75.

  In the a row i column, when the operating body 6 stops at the minimum rotation stop position P1 that cannot be further rotated to the left side, as shown in the b row i column, a large arc-shaped convex portion in the rotor 76 of the shock absorber 12 is shown. 1/3 of 80 faces the small internal hole 77 from the large internal hole 78 in the stator 75, and the shock absorber 12 generates a small torque T2 that is slightly larger than the minimum torque T1, as shown in line c. When the operating body 6 is rotated to the right from the minimum rotation stop position P1, for example, by 22.5 degrees and stopped at the operation position P2 in the a-row and the ro-column, as shown in the b-row and the ro-column, the shock absorber 2/3 of the large arc-shaped convex portion 80 of the 12 rotors 76 faces the small internal hole 77 from the large internal hole 78 in the stator 75, and the shock absorber 12 is slightly larger than the small torque T2 as shown in line c. In this configuration, torque T3 is generated. When the operating body 6 is in the range between the minimum rotation stop position P1 and the operating position P2, the variable resistor 11 shown in FIG. 2 that rotates together with the operating body 6 gives the variable resistance value to the control device (not shown). What is output, the control device does not drive the firing mechanism 88 of FIG. 9, and the firing mechanism 88 does not fire a sphere.

The large arc-shaped convex part 80 in FIG. 3 is opposed to the small internal hole 77 from the large internal hole 78 in the stator 75, and the shock absorber 12 starts to generate the maximum torque T4 as shown in the c-th line. When the operating body 6 is in the range between the operating position P2 and the operating position P3, the variable resistor 11 that rotates together with the operating body 6 outputs a variable resistance value to the control device, and the control device outputs the firing mechanism 88. And the firing mechanism 88 fires a sphere. However, the ball fired from the launching mechanism 88 does not go out from the launching passage 94 shown in FIG. In other words, when the operating body 6 is in the range between the operating position P2 and the operating position P3, the ball fired from the launching mechanism 88 is not fired into the game area 91 and returns to the launch path 94, The foul ball returned to the dish device 87 shown in FIG.

  In the a row and the second column, the operating body 6 is rotated to the right side from the operation position P3, for example, by 45 degrees and stopped at the operation position P4, and as shown in the b row and the second column, a large arc shape in the rotor 76 of the shock absorber 12 is formed. When the leading end of the convex portion 80 in the rotational direction faces the boundary between the large internal hole 78 and the small internal hole 77 in the stator 75, the shock absorber 12 finishes generating the maximum torque T4 as shown in line c. is there. When the operating body 6 is in the range between the operating position P3 and the operating position P4, the variable resistor 11 that rotates together with the operating body 6 outputs a variable resistance value to the control device, and the control device performs the launch mechanism. 88 is driven, and the ball fired from the launching mechanism 88 is launched from the launch passage 94 to the game area 91. In other words, when the operating body 6 is in the range between the operating position P3 and the operating position P4, the ball fired from the launching mechanism 88 is launched into the game area 91, and the shock absorber 12 outputs a constant maximum torque. To do. When the operating body 6 reaches the operating position P4, the ball launched from the launching mechanism 88 to the game area 91 collides with a ball repelling body 96 called a rebound rubber shown in FIG. .

  When the operating body 6 is rotated to the right from the operation position P4, for example, by 22.5 degrees in the a row and column, and stopped at the maximum rotation stop position P5 that does not rotate further to the right side, as shown in the b row and column. Further, 1/3 of the large arc-shaped convex portion 80 in the rotor 76 of the shock absorber 12 faces the large internal hole 78 in the stator 75, and as shown in FIG. C, the shock absorber 12 is reduced to the medium torque T3 from the maximum torque T4. It is a form which generate | occur | produces. And when the operating body 6 exists in the range of the operation position P4 and the maximum rotation stop position P5, the variable resistor 11 that rotates together with the operating body 6 outputs a variable resistance value to the control device, and the control device The launch mechanism 88 is driven, and the ball launched from the launch mechanism 88 to the game area 91 collides with the ball repulsion member 96 vigorously. In other words, when the operating body 6 is in the range between the operating position P4 and the maximum rotation stop position P5, the ball fired from the launching mechanism 88 collides with the ball repulsion body 96 vigorously, and the shock absorber 12 reaches the maximum. This is a range in which a torque between the torque T4 and the intermediate torque T3 is generated.

  Considering FIG. 8, when the operating body 6 is operated in the range between the minimum rotation stop position P1 and the operating position P3, the ball is not launched into the game area 91, and the shock absorber 12 has the small torque T2 and the maximum torque. Since it changes within the range of T4, the player can easily rotate the operation body 6 from the minimum rotation stop position P1 to the operation position P3. When the operating body 6 is operated in the range between the operating position P3 and the operating position P4, the ball is launched to the upper part of the game area 91, and the shock absorber 12 has a constant maximum torque T4. Therefore, when the player fixes the operation body 6 between the operation position P3 and the operation position P4 and the operation body 6 is fixed to the adjustment position desired by the player, the operation body 6 is held at the maximum torque T4 by the shock absorber 12. Therefore, the player can fix the operating body 6 at the adjustment position with a weak force, and the fatigue of the player's firing operation can be reduced.

  With reference to FIG. 9, a pachinko machine exemplified as a gaming machine to which the firing operation mechanism 1 is attached will be described. The gaming machine frame 85 of the pachinko machine is attached to a gaming machine installation facility called an island of a pachinko shop. The gaming machine frame 85 includes a front decorative body 86, a dish device 87, and the firing operation mechanism 1 on the front surface, and a firing mechanism 88 inside. The dish apparatus 87 constitutes the mating member 66 shown in FIG. Then, by storing the game board 89 inside the gaming machine frame 85, the inner game area 91 surrounded by the guide rail 90 on the front surface of the game board 89 closes the window 92 of the front decorative body 86 or Covered with a light-transmitting front panel 93 made of synthetic resin. When a ball is placed in the dish device 87 and the player rotates the operation body 6 of the firing operation mechanism 1 to the right side, for example, the firing mechanism 88 launches the ball supplied from the dish device 87 toward the game area 91. . The fired ball is launched into the space between the front panel 93 and the game area 91 via the launch passage 94 and the ball return prevention valve 97 partitioned by the guide rail 90, and a winning component 95 in the game area 91 is obtained. When a prize is won, a ball as a prize ball is paid out to the dish device 87 from the back side of the gaming machine frame 85. In FIG. 9, reference numeral 96 denotes a ball repulsion body, 97 denotes a ball return prevention valve, and 98 denotes an out port.

  According to this best mode, the three spur gears 3-5 provided rotatably on the mechanism housing 2 and the one annular gear 7 fixedly provided on the operating body 6 are meshed with each other, The front cover 45 is put on the front side of the operation body 6, and the plurality of mounting legs 47 of the front cover body 45 and the plurality of support posts 28 of the operation body 6 are fastened by the set screw 31 from the back side of the mechanism housing 2. The mechanism housing 2 and the front cover body 45 are fixed to each other in such a manner that the operating body 6 is rotatably interposed between them. Therefore, a plurality of constituent members including the mechanism housing 2 provided with the spur gear 3-5, the operation body 6 provided with the annular gear 7 and the front cover 45 are attached so as not to be separated from each other only by the set screw 31. Because of this structure, there is an advantage that the assembling work and the disassembling work of the plurality of constituent members are simple. Moreover, the operating body 6 is engaged with the mechanism housing 2 and the front cover 45 by the meshing between the spur gear 3-5 on the mechanism housing 2 side and the annular gear 7 on the operation body 6 side. It can rotate around the center of the operating body 6 coaxial with the center. Therefore, since the spur gear 3-5 and the annular gear 7 meshed with each other at a portion radially away from the center of the operation body 6 support the operation body 6 rotatably with respect to the mechanism housing 2, the mechanism housing is provided. Compared to the structure in which the shaft for rotatably supporting the operating body 6 is provided at the center portion of 2, there is an advantage that the operating body 6 can rotate smoothly without rattling. In addition, a shaft for rotatably supporting the operation body 6 can be removed from the central portion of the mechanism housing 2, and if the shaft is removed, an internal space surrounded by the operation body 6 and the front cover body 45 is formed. There is an advantage that a contact detector made of a semiconductor device that senses human contact is arranged in the enlarged internal space, and the contact detector can be easily attached to the operating body 6. Since the volume shaft 15 and the damper shaft 17 are individually connected to the two spur gears 4; 5, two of the three spur gears 3-5 that rotatably support the operating body 6 with respect to the mechanism housing 2. There is an advantage that it is a simple structure in which the individual is utilized for the operation of the variable resistor 11 and the shock absorber 12.

  According to this best mode, at least one of the struts 28 abuts against one end in the circumferential direction of the escape hole 36, so that the operating body 6 of the firing operation mechanism 1 is stopped at the minimum rotation stop position P1. When the player rotates the operation body 6 of the firing operation mechanism 1 to the right, for example, the damper shaft 17 of the shock absorber 12 and the volume shaft 15 of the variable resistor 11 rotate. As the damper shaft 17 rotates, the shock absorber 12 generates a torque that gradually increases from the small torque T2, and as the volume shaft 15 rotates, the variable resistor 11 gradually changes the variable resistance value. Output to the control device. When the rotated operating body 6 exists in the range of the operation position P3 and the operation position P4, the ball is moved to the game area 91 by the electrical output from the control device in which the launch mechanism 88 receives the variable resistance value. Fire. When the ball is reliably launched into the game area 91, the shock absorber 12 is configured to generate a certain maximum torque T4, so that the operating body 6 is placed at the adjustment position that the player desires most during the game. There is an advantage that fine adjustment can be easily performed. In the present embodiment, the structure is such that the spring for returning the operating body 6 whose operating force has been released to the direction of the minimum rotation stop position P1 is removed such that the player releases his hand from the operating body 6 that has been rotated. Therefore, the player adjusts the operating body 6 to the adjustment position desired by the player in the range between the operation position P3 and the operation position P4 with a weaker force than resisting the return force of the spring, and the shock absorber 12 However, since the operating body 6 can be fixed at this adjustment position, there is an advantage that fatigue due to the launching operation of holding the operating body 6 at the adjustment position desired by the player can be most reduced. Since the commercially available rotary damper can be used as the shock absorber 12, there is an advantage that using the commercially available product is more economical than using the shock absorber 12 manufactured independently. is there.

  The shock absorber 100 that outputs a constant torque shown in FIG. 10 may be replaced with a shock absorber 12 that outputs a variable torque shown in the best mode. The shock absorber 100 includes a stator 102 that forms one circular chamber 101 having a radius of curvature centering on the center of the damper shaft 17, and an oval rotor 103 that rotates on the damper shaft 17. A circular outer peripheral surface 104 having one radius of curvature around the center of the damper shaft 17 in the rotor 103 is smaller than the radius of curvature of the chamber 101 of the stator 102. A gap between the parallel opposite side surfaces 105 sandwiching the damper shaft 17 in the rotor 103 and the circular inner peripheral surface of the chamber 101 of the stator 102 forms a plurality of wide liquid chambers 106, and the circular shape of the rotor 103 A plurality of narrow passages 107 connecting the plurality of wide liquid chambers 106 are formed between the outer peripheral surface 104 and the circular inner peripheral surface of the chamber 101 of the stator 102. When the rotor 103 rotates with the rotation of the damper shaft 17, the viscous fluid in one wide liquid chamber 106 flows into the other wide liquid chamber 106 via the narrow passage 107, thereby generating a constant torque.

  Although the operation body 6 is held at the adjustment position desired by the player to reduce the fatigue due to the launching operation, the shock absorber 12 is removed, and the player releases his hand from the operation body 6 that has been rotated. In this case, the structure can be similarly applied even to a structure using a spring that returns the operating body 6 to the direction of the minimum rotation stop position P1. The number of spur gears 3-5 is not limited to three. For example, two spur gears are individually provided at the intersection of a straight line passing through the center of the head 9 of the mechanism housing 2 and one circumference centered on the center of the head 9, or three or more spur gears are provided. What is necessary is just to provide also in one circumference centering on the center of the head 9. FIG. However, if the three spur gears 3-5 are used as in the best mode, the radial rattling at the meshing portion between the three spur gears 3-5 and the annular gear 7, that is, the operating body 6 Reduces shakiness.
