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 made of a transparent synthetic resin and has a substantially concave longitudinal section, 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.

  As shown in FIGS. 11 and 12, the volume adjusting knob 91 is formed with a plurality of protruding portions 92 so as to surround the outer peripheral surface at the lower end thereof. In other words, as shown in FIG. 12, when the volume control knob 91 is viewed from above, the plurality of protrusions 92 are formed radially from the outer peripheral surface of the volume control knob 91. In other words, the plurality of projecting portions 92 are formed in the shape of petals. The surface 92a of each protrusion 92 is formed as a bulged curved surface. In other words, it is formed in a shape obtained by cutting a part of the sphere. Each protrusion 92 corresponds to the arrangement position of the protrusions 103a formed on the rotor 103 of the rotary switch 97, and the outer periphery of the volume control knob 91 so as to have the same number as the number of the protrusions 103a. Formed on the surface. A recess 92 b is formed between the protrusions 92. Each recess 92b is formed so as to correspond to the 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 recesses 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.
Further, a groove 94 for inserting a tip of a minus driver or the like is formed at the upper end of the volume control knob 91.

  As shown in FIG. 8, an opening 76 b for projecting the tip of the volume control knob 91 is formed in the step portion 76 of the cover 75. A notch 76a is formed at the periphery of the opening 76b, and a biasing member 77 is formed between the notch 76a and the opening 76b. The urging member 77 urges the surface 92a of the protruding portion 92 of the volume adjusting knob 91 from above, and includes a fixed end 77a fixed to the stepped portion 76 and an extending portion extending from the fixed end 77a. 77b, a free end 77c formed at the tip of the extending portion 77b, and a pressing portion 77d formed at the free end.

  The extending portion 77b extends to the vicinity of the volume control knob 91 inserted through the opening 76b. The urging member 77 is integrally formed of the same synthetic resin as the stepped portion 76, utilizes the elasticity of the synthetic resin, and has a spring property. When a stress acts in a direction substantially orthogonal to the pressing portion 77d, the urging member 77 is configured such that the free end 77c swings up and down with the fixed end 77a as a fulcrum.

  As shown in FIG. 9, a portion of the pressing portion 77d that presses the surface 92a of the protruding portion 92 of the volume adjusting knob 91 is formed as a bulged curved surface. In other words, the contact friction resistance is reduced by the contact between the curved surface of the pressing portion 77d and the curved surface of the protruding portion 92, and it rides on the surface 92a of the protruding portion 92 when the volume control knob 91 rotates. The pressing portion 77d is configured to slide down into the hollow portion 92b without resistance.

  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. Has been.

  In addition, a wall 78 protrudes from the stepped portion 76. The wall 78 is integrally formed of the same synthetic resin as the stepped portion 76. The wall 78 is disposed on the opposite side of the urging member 77 b with the opening 76 interposed therebetween, and is formed at a distance from the periphery of the opening 76. The wall 78 is formed at a position where the outer edge of each projecting portion 92 can contact when the volume control knob 91 rotates, and the portion of the wall 78 that faces each projecting portion 92 is each projecting portion that rotates. It is formed in an arc shape corresponding to the locus drawn by 92. That is, when the volume control knob 91 is rotated, the outer edge of each protrusion 92 is configured to rotate while contacting the wall 78, and the wall 78 guides each protrusion 92 in the rotation direction. The volume control knob 91 plays a role of rotating stably.

  As shown in FIG. 9, a volume adjustment knob 91 is put on the shaft member 98 of the rotary switch 97, and the volume adjustment knob 91 protrudes upward from an opening 76 b formed in the stepped portion 76 of the cover 75. . FIG. 9 shows the moment when the pressing portion 77d of the urging member 77 rides on the surface 92a of the protruding portion 92 of the volume adjusting knob 91 and the pressing portion 77d presses the surface 92a from above when the volume adjusting knob 91 is rotated. Is shown. When the volume control knob 91 is not rotated, the pressing portion 77d is slid down from the surface 92a of the protruding portion 92 to the recessed portion 92b. Further, the protruding portion 92 opposite to the protruding portion 92 biased by the pressing portion 77 d is rotatable along the wall 78.

  FIG. 14 is an explanatory diagram for explaining the force exerted by the pressing portion of the urging member on the protruding portion of the volume control knob, and (a) shows a state in which the pressing portion is fitted in a recess between the protruding portions. , (B) shows the state where the pressing part has started to rise up the surface of the protruding part, (c) shows the state where the pressing part rides on the top of the protruding part, (d) shows the pressing part from the top of the protruding part Indicates the state of sliding down.

  In a normal use state where the volume control knob 91 is not rotated, as shown in FIG. 14A, the pressing portion 77d of the biasing member 77 is fitted into a recess 92b between the protruding portions 92 of the volume control knob 91. It is in the state. Then, when the volume adjustment knob 91 is rotated in the direction indicated by the symbol R in the drawing, the pressing portion 77d starts to rise up the surface of the protruding portion 92 adjacent to the recessed portion 92b, as shown in FIG. 14 (b). At this time, the pressing portion 77d starts to press the surface 92a of the protruding portion 92 that has started to rise due to the elastic force of the biasing member 77. The force F1 at which the pressing portion 77d presses the surface 92a of the protruding portion 92 increases as the pressing portion 77d approaches the top of the protruding portion 92.

  When the volume control knob 91 is further rotated, the pressing portion 77d gets over the top of the protruding portion 92 as shown in FIGS. 14 (c) and 14 (d). As shown in FIG. 14C, when the pressing portion 77d reaches the top of the protruding portion 92, the force F1 at which the pressing portion 77d presses the protruding portion 92 is maximized. Since the surface 92a of the protruding portion 92 is formed as a bulged curved surface, the contact area between the pressing portion 77d and the top of the protruding portion 92 is small, so that the pressing portion 77d rides on the top of the protruding portion 92. It becomes difficult to maintain.

  Moreover, in this embodiment, since the part which presses the protrusion part 92 among the press parts 77d is formed in the bulged curved surface, the contact area of the press part 77d and the top part of the protrusion part 92 is still smaller. It becomes even more difficult to maintain the state in which the pressing portion 77d rides on the top of the protruding portion 92. Further, in this embodiment, since the pressing portion 77d and the protruding portion 92 are both made of synthetic resin, the friction at the portion where the pressing portion 77d and the top of the protruding portion 92 are in contact with each other is much smaller. However, it is more difficult to maintain the state in which the motor rides on the top of the protrusion 92.

For this reason, the pressing portion 77d does not stagnate at the top of the protruding portion 92, and always slides down the surface 92a of the protruding portion 92 as shown in FIG. At this time, the force F1 that the pressing portion 77d presses the protruding portion 92 decreases, but a force F2 that pushes the protruding portion 92 that has been overcome in the rotation direction of the volume adjusting knob 92 is generated. Even without adding, the volume control knob 91 rotates and the pressing portion 77d slides down to the next hollow portion 92d.
That is, when the volume control knob 91 is rotated, the pressing portion 77d is always fitted to any of the hollow portions 92b without staying at the top of the protruding portion 92.

Further, when the pressing portion 77d is fitted in the recess 92b, the fitting portion 99b formed in the spring 99 of the rotary switch 97 is in a state fitted in the recess 103b formed in the rotor 103. Therefore, the fitting part 99b does not ride on the flat top part of the convex part 103a and stay in a stationary state.
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. Further, when the pressing portion 77d slides down the surface 92a of the projecting portion 92, a sound (for example, a clicking sound) that the pressing portion 77d and the recessed portion 92b collide is generated. By counting, the rotation amount of the volume control knob 91, that is, the volume can be known.

Further, the number of protrusions 92 is the same as the number of protrusions 103a formed on the rotor 103 of the rotary switch 97, and the number of recesses 92b is the same as the number of recesses 103b. The rotational position of the knob 91 corresponds to the rotational position of the rotor 103. In addition, the arrangement position of the protruding portion 92 matches the arrangement position of the convex portion 103a, and the arrangement position of the recessed portion 92b matches the arrangement position of the concave portion 103b.
For this reason, 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.

[Effect of the first embodiment]
(1) As described above, when the pachinko machine 1 according to the first embodiment is used, the pressing portion 77d formed on the free end 77c of the biasing member 77 when the volume control knob 91 is rotated is the protruding portion 92. There is no risk of stopping at the top of the.
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) Further, the urging member 77 is formed at the fixed end 77a fixed to the stepped portion 76 of the cover 75, the extending member 77b extending from the fixed end 77a, and the tip of the extending member 77b. Since the configuration includes the free end 77c and the pressing portion 77d formed on the free end 77c, the amplitude of the pressing portion 77d can be made larger than the configuration in which both ends of the extending member 77b are fixed. .
Therefore, since the resistance force when the pressing portion 77d gets over the top of the protruding portion 92 of the volume control knob 91 does not become excessively large, the volume control knob 91 can be easily rotated.

(3) Further, among the pressing portions 77d provided in the urging member 77, the portion that presses the surface 92a of the protruding portion 92 of the volume adjusting knob 91 is formed in a curved surface. Since the curved surfaces come into contact with each other, the frictional force due to the contact can be reduced.
That is, the pressing portion 77d can easily slide down from the top of the protruding portion 92 to the hollow portion 92b, and can hardly stop at the top of the protruding portion 92.

(4) Further, since the urging member 77 is integrally formed with the stepped portion 76 of the cover 75 by a synthetic resin material, the urging member 77 can be formed simultaneously with the cover 75, and the urging member 77 is also formed. 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.

(5) Furthermore, since the urging member 77 is formed by a relatively simple method of forming the notch 76a at the periphery of the opening 76b formed in the cover 75, the urging member 77 is formed. Work efficiency can be increased.

(6) Further, since the number of the recesses 103b formed on the rotation plane of the rotor 103 and the number of the recesses 92b formed between the protrusions 92 formed on the volume control knob 91 are the same, the volume control knob Since the rotational position of 91 and the rotational position of the rotor 103 can be matched, the volume is adjusted by rotating the shaft member 98 and adjusting the volume by rotating the volume adjustment knob 91 placed on the shaft member 98. The number of volume adjustment steps can be matched with the case of doing.

(7) 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.

<Other embodiments>
(1) Without forming the notch 76a at the periphery of the opening 76b, the thickness of a part of the periphery of the opening 76b is thinned, and the thin part is set as the biasing member 77, and the predetermined portion Alternatively, the pressing portion 77d can be formed.

(2) A symbol such as a number indicating the volume level may be printed on the periphery of the opening 76 b, and a mark indicating the volume adjustment start position may be displayed on the outer peripheral surface of the volume adjustment knob 91. By using this configuration, it is possible to easily grasp the volume level when the volume control knob 91 is rotated.

(3) A metal leaf spring whose tip is bent into a V shape is used as the urging member 77, and the base end of the urging member 77 is fixed to the stepped portion 76 of the cover 75 to become a free end. The convex portion of the V-shaped portion at the tip can be configured to press the protruding portion 92 of the volume control knob 91.

(4) The present invention can be applied to a gaming machine in which a rotary switch is mounted on a control board, such as a slot machine other than a pachinko machine or a game machine installed in a game center.
