FIG. 8 is an enlarged perspective view showing the back surface of the cover where the volume control device 90 shown in FIG. 7 is provided, and FIG. 9 is a cross-sectional view taken along line AA in FIG. FIG. 10 is an enlarged perspective view showing the rotary switch constituting the volume control device 90 shown in FIG. 11 is an enlarged front view showing the volume control knob constituting the volume control device 90 shown in FIG. 7, FIG. 12 is a plan view of the volume control knob shown in FIG. 11, and FIG. 11 is a rear view of the volume control knob shown in FIG.
Note that the same reference numerals are used for the same components as those of the conventional rotary switch 100 shown in FIG. 15, and description thereof is omitted or simplified.

  As shown in FIG. 6, a cover 75 that covers the board surface is assembled to the audio / video control board 70. The cover 75 is formed in a box shape from a transparent synthetic resin, and the substrate surface of the audio / video control board 70 can be visually recognized from the outside of the cover 75. On the surface of the cover 75, a plurality of terminals 70 a disposed on the board surface of the audio / video control board 70 are exposed. A step portion 76 is formed in the cover 75, and a part of the volume control device 90 is accommodated in the step portion 76.

  An opening 76b is formed in the stepped portion 76, and the tip of the volume control knob 91 protrudes from the opening 76b. That is, the volume of the speakers 10 to 12 can be adjusted by rotating the volume control knob 91 protruding from the opening 76b.

  As shown in FIG. 10, the rotary switch 97 that constitutes the volume control device 90 has substantially the same structure as the conventional rotary switch 100 shown in FIG. The shaft member 98 for rotating the rotor 103 has a base end fixed to the rotation center of the rotor 103 and a tip protruding from the surface of the housing 104. On the surface of the shaft member 98, an insertion port 98a for inserting the tip of a minus driver is formed. Further, on the outer peripheral surface of the shaft member 98, a fitting groove 98b for fitting a fitting protrusion 96 (FIG. 13) formed in the insertion port 95 of the volume adjusting knob 91 is formed along the rotation axis. Yes.

  As shown in FIG. 11, the volume control knob 91 is formed in a cylindrical shape whose upper end is closed, and a plurality of anti-slip grooves 91a are formed on the outer peripheral surface along the rotation axis. . Further, on the outer peripheral surface of the volume control knob 91, a convex locking portion 93 is formed at a portion facing the opening 76b (FIG. 8) of the stepped portion 76. The engaging portion 93 is configured to be able to be engaged with a restricting portion 79 (FIG. 8) that protrudes from the periphery of the opening 76 b, and the engaging portion 93 is engaged with the restricting portion 79. The amount of rotation of the volume control knob 91 is restricted.

  As shown in FIG. 13, an insertion port 95 for inserting the shaft member 98 of the rotary switch 97 is formed inside the volume control knob 91. A fitting projection 96 for fitting into the fitting groove 98 b of the shaft member 98 is formed on the inner wall of the insertion port 95 so as to protrude. In other words, by covering the shaft member 98 with the volume adjustment knob 91 so that the fitting protrusion 96 is fitted in the fitting groove 98b, the volume adjustment knob 98 is prevented from idling and the volume adjustment knob 98 is rotated. The shaft member 98 rotates.

  Also, as shown in FIGS. 11 and 12, a flange 92 is formed in a bowl shape so as to surround the outer peripheral surface from the outer peripheral surface of the lower end of the volume control knob 91. A rotating gear portion 96 is formed on the rotation plane of the surface of the flange portion 92. In the rotating gear part 96, a tooth bottom 96b having a V-shaped longitudinal section and a tooth tip 96a having a sharp tip are alternately formed along the rotation direction. In other words, the rotating gear portion 96 is formed in the shape of a face gear.

  Further, as shown in FIG. 8, a portion of the back surface of the stepped portion 76 formed on the cover 75, which is the periphery of the opening 76 b and faces the rotating gear portion 96 of the volume adjusting knob 91, has a rotating gear portion. A fixed gear portion 77 meshing with 96 is formed. In the fixed gear portion 77, a tooth bottom 77b having a V-shaped longitudinal section and a tooth tip 77a having a sharp tip are alternately formed along the periphery of the opening 76b.

The tooth tip 77 a of the fixed gear portion 77 meshes with the tooth bottom 96 b of the rotating gear portion 96, and the tooth bottom 77 b of the fixed gear portion 77 meshes with the tooth tip 96 a of the rotating gear portion 96. Since both the tooth tip 96a of the rotating gear portion 96 and the tooth tip 77a of the fixed gear portion 77 are pointed, the contact area between the tip of the tooth tip 96a and the tip of the tooth tip 77a is very small. Further, the tooth tip 96a and the tooth tip 77a are both made of synthetic resin and have low frictional resistance. For this reason, when the rotation gear part 96 rotates, there is no possibility that the tooth tip 96a of the rotation gear part 96 gets on the tooth tip 77a of the fixed gear part 77 and stops.
Therefore, the conductive pattern formed on the back surface of the rotor 103 and the contact 106a are not electrically connected, and a situation in which no sound is produced from the speakers 10 to 12 does not occur.

  A restricting portion 79 for restricting the rotation of the volume adjusting knob 91 is formed on the periphery of the opening 76d so as to be engaged with the engaging portion 93 of the volume adjusting knob 91 when the volume adjusting knob 91 rotates. Yes. As shown in FIG. 12, a groove 94 for inserting a tip of a minus driver is formed at the upper end of the volume control knob 91.

  The tooth tips 96a of the rotating gear portion 96 are formed so as to correspond to the arrangement positions of the convex portions 103a formed on the rotor 103 of the rotary switch 97 and to have the same number as the convex portions 103a. . Further, the tooth bottom 96b is formed so as to correspond to the arrangement position of the recess 103b formed in the rotor 103 of the rotary switch 97 and to be the same number as the number of the recess 103b.

  Further, the tooth tips 77a of the fixed gear portion 77 are formed so as to correspond to the arrangement positions of the convex portions 103a formed on the rotor 103 of the rotary switch 97 and to have the same number as the number of the convex portions 103a. ing. Further, the tooth bottom 77b is formed so as to correspond to the arrangement position of the recess 103b formed in the rotor 103 of the rotary switch 97 and to be the same number as the number of the recess 103b.

In other words, when the rotor 103 of the rotary switch 97 rotates, the number of times that the fitting portion 99b of the spring 99 falls over the convex portion 103a of the rotor 103 and falls into the concave portion 103b, that is, the number of volume adjustment steps is determined by the volume adjustment knob 91. The shaft member 98 is directly rotated without being used, and is configured to be the same when the volume adjustment knob 91 placed on the shaft member 98 is rotated.
Therefore, the number of steps of adjustable volume does not change between when the shaft member 98 of the rotary switch 97 is directly rotated and when the volume adjustment knob 91 placed on the shaft member 98 is rotated.

  As shown in FIG. 9, a coil spring 78 that biases the flange 92 of the volume control knob 91 upward is provided between the front surface of the housing 104 of the rotary switch 97 and the back surface of the flange 92 of the volume control knob 91. Is provided. A shaft member 98 protruding from the housing 104 is inserted into the center of the coil spring 78. The rotating gear portion 96 formed on the surface of the flange portion 92 of the volume control knob 91 is pressed against the fixed gear portion 77 formed on the back surface of the stepped portion 76 by the spring force of the coil spring 78. That is, the rotating gear portion 96 and the fixed gear portion 77 are maintained in a state where they are engaged with each other by the spring force of the coil spring 78.

  14A and 14B are explanatory views showing a state in which the flange portion 92 of the volume control knob 91 rotates, where FIG. 14A shows a state in which the rotating gear portion 96 and the fixed gear portion 77 are engaged, and FIG. 14B shows a rotating gear portion. 96 shows a state in which the meshing state of 96 and the fixed gear portion 77 is released, and (c) shows a state in which the tooth tip 96a of the rotating gear portion 96 is about to get over the tooth tip 77a of the fixed gear portion 77.

  In a normal use state where the volume control knob 91 is not rotated, as shown in FIG. 14A, the rotating gear portion 96 formed on the flange portion 92 of the volume control knob 91 is formed on the back surface of the stepped portion 76. It is in a state of meshing with the fixed gear portion 77. Then, when the volume adjustment knob 91 is rotated in the direction indicated by the symbol R in the drawing, the state where the rotating gear portion 96 and the fixed gear portion 77 are engaged is released as shown in FIG.

  When the volume control knob 91 is further rotated in the direction indicated by the symbol R, the tooth tip 96a of the rotating gear portion 96 tries to get over the tooth tip 77a of the fixed gear portion 77 as shown in FIG. To do. At this time, the tooth tips 96a of the rotating gear portion 96 and the tooth tips 77a of the fixed gear portion 77 are both sharply pointed, so that the tooth tips 96a of the rotating gear portion 96 ride on the tooth tips 77a of the fixed gear portion 77. There is no risk of stopping in a state.

  Then, when the tooth tip 96a of the rotating gear portion 96 gets over the tooth tip 77a of the fixed gear portion 77, the spring force of the coil spring 78 slides down the slope of the tooth tip 77a that has been passed over to the tooth bottom 77b at the tip. Mated.

  Thus, when the volume control knob 91 is rotated, the volume control knob 91 resists the spring force of the coil spring 78 until the tooth tip 96 a of the rotating gear portion 96 gets over the tooth tip 77 a of the fixed gear portion 77. The volume control knob 91 receives the spring force of the coil spring 78 from when the tooth tip 96a gets over the tooth tip 77a to when the tooth tip 96a is fitted to the tooth bottom 77b. Rotates automatically without adding.

  That is, the person who rotates the volume control knob 91 can rotate the volume control knob 91 while feeling the spring force of the coil spring 78 every time the tooth top 96a of the rotating gear section 96 gets over the tooth top 77a of the fixed gear section 77. it can. In other words, a person who rotates the volume adjustment knob 91 can rotate the volume adjustment knob 91 while feeling a so-called click whenever the tooth tip 96a of the rotating gear portion 96 gets over the tooth tip 77a of the fixed gear portion 77. it can.

  In addition, when the tooth tip 96a of the rotating gear portion 96 slides down on the tooth bottom 77b of the fixed gear portion 77, a sound (for example, a clicking sound) that the tooth tip 96a collides with the tooth bottom 77b is generated. By counting the number of times the sound is generated, the rotation amount of the volume control knob 91, that is, the volume can be known.

  Further, since the rotating gear portion 96 is biased to the fixed gear portion 77 by the coil spring 78, in the state where the rotating gear portion 96 and the fixed gear portion 77 are engaged with each other, unless the volume control knob 91 is rotated, the rotating gear portion 96 is engaged. In order to maintain the state, there is no possibility that the volume control knob 91 rotates naturally and the set volume changes.

[Effect of the first embodiment]
(1) As described above, when the pachinko machine 1 according to the first embodiment is used, when the volume control knob 91 is rotated, the teeth of the rotating gear part 96 formed on the flange 92 of the volume control knob 91 There is no possibility of stopping when the tip 96a rides on the tooth tip 77a of the fixed gear portion 77 formed on the back surface of the cover 75.
That is, there is no possibility that the fitting portion 99b of the spring 99 that biases the convex portion 103a and the concave portion 103b of the rotor 103 from above stops on the flat top of the convex portion 103a. It is possible to prevent a situation where no sound is generated from 10 to 12.

(2) Since the fixed gear portion 77 is integrally formed with the stepped portion 76 of the cover 75 using a synthetic resin material, the fixed gear portion 77 can be formed simultaneously with the cover 75, and the fixed gear portion 77. Since it is not necessary to mold the material with a material different from that of the cover 75, the manufacturing efficiency of the gaming machine 1 can be increased.

(3) Further, the number of recesses 103 b formed on the rotation plane of the rotor 103, the number of tooth bottoms 96 b formed on the rotation gear portion 96 of the volume control knob 91, and the fixed gear portion that meshes with the rotation gear portion 96. Since the number of the tooth bottoms 77b formed on 77 is the same, the rotation position of the volume control knob 91 and the rotation position of the rotor 103 can be matched, so that the volume is adjusted by rotating the shaft member 98. The number of volume adjustment steps can be matched between the case and the case where the volume adjustment knob 91 placed on the shaft member 98 is rotated to adjust the volume.

(4) Further, on the outer peripheral surface of the volume control knob 91, a convex locking portion 93 is formed at a portion facing the inner peripheral edge of the opening 76b from which the volume control knob 91 protrudes. A restricting portion 79 that restricts the rotation of the volume adjusting knob 91 by engaging with the engaging portion 79 when the volume adjusting knob 91 rotates is formed on the periphery of 76b.
Therefore, by associating the position where the rotation of the volume adjustment knob 91 is restricted with the adjustment position of the volume to be set, if the volume adjustment knob 91 is rotated until it is restricted, the volume to be set is reached. Can be easily adjusted. Further, if the position where the rotation of the volume control knob 91 is restricted is associated with the position of the minimum volume, the rotation position of the minimum volume can be easily known. In addition, the volume can be easily adjusted in steps from the minimum volume.
