Abstract

<P>PROBLEM TO BE SOLVED: To supply a pinball game machine that can switch the states (game ball shoot permission state and game ball shoot prohibiting state) and prevent deterioration or breakage of a part contacting with a rotary operation part. <P>SOLUTION: This pachinko game machine lessens the shocks at the parts mutually contacting with a turning operation member 81 and a shooting switch 100 compared with a conventional pinball game machine because an outward face 110A of a rotary wall 110 formed in a turning operation member 81 and an inward face 109A of a receiving wall 109 provided in the shooting switch 100 mutually slide and touch each other and the turning wall 110 depresses the receiving wall 109 as if the rotary wall 110 gradually pushes the receiving wall 109 outside while a turning operation member 81 is rotating from a turning condition to a turning start point (while the shooting switch 100 changes from an off state to an on state). This can prevent deteriorations or breakages of the turning wall 110 of the turning operation member 81 and the receiving wall 109 of the shooting switch 100. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a ball game machine.

  In general, a ball game machine is provided with an operation knob for launching a game ball toward a game area. Further, some conventional operation knobs include a firing changeover switch that can be switched between an on state in which the launch of a game ball by turning the operation knob is permitted and an off state in which the launch of the game ball is prohibited. (For example, refer to Patent Document 1).

  Specifically, as shown in FIG. 18, the operation knob includes a fixed portion 1 fixed to the front surface of the ball game machine, and a rotation operation portion pivotally supported with respect to the fixed portion 1. 2, and the firing changeover switch 3 is fixed inside the fixing portion 1. In addition, contact pieces 4 and 4 that can contact each other are formed on the rotation operation unit 2 and the firing changeover switch 3.

And in the rotation start point position where the rotation operation part 2 is not rotated with respect to the fixed part 1, these contact pieces 4 and 4 contact each other and the firing changeover switch 3 is in an OFF state (state of FIG. 18). On the other hand, when the rotation operation unit 2 is rotated with respect to the fixed unit 1 in a predetermined direction (counterclockwise direction in FIG. 18), the contact pieces 4 and 4 are separated from each other and the firing changeover switch 3 is turned on. It is comprised so that.

[Invention of Claim 1]
According to the first aspect of the invention configured as described above, the changeover switch member and the on / off switching are performed while the changeover switch member is displaced between the on position and the off position in accordance with the rotation of the rotation operation member. Since the members are in sliding contact with each other, the impact applied to the contact portions can be reduced as compared with the case where the contact portions collide with each other as in the conventional ball game machine. Moreover, since at least one sliding contact portion of the changeover switch member and the on / off switching member is formed with an arc-shaped switch switching sliding contact surface along substantially the same direction as the rotational direction of the rotational operation member, After the rotation operation member is rotated toward the rotation start point and the changeover switch member is displaced to the off position, the force from the on / off changeover member can be released. Thereby, since the impact applied to the mutual contact portion between the changeover switch member and the on / off changeover member is more reliably mitigated, deterioration or breakage of at least one contact part of the changeover switch member and the on / off changeover member can be suppressed. .

[Invention of claim 2]
According to the invention of claim 2, since the switch switching slidable contact surface is formed at the mutual slidable contact portion between the changeover switch member and the on / off switching member, the slidable contact portions are easily slidable.

[Invention of claim 3]
According to the invention of claim 3, when the changeover switch member moves from the on position to the off position, the changeover switch member is tilted by contact with the on / off changeover member, and the changeover switch member is provided by this tilting. The sliding contact area where the switch switching sliding contact surface and the switch switching sliding contact surface provided on the on / off switching member contact each other increases. Thereby, even if the force to turn the changeover switch member to the off position increases from the on position to the off position, the force can be gradually dispersed. That is, it is possible to suppress the concentration of the pressing force on a specific portion of the switch switching sliding contact surface provided in the switch member.

[Invention of claim 4]
According to the invention of claim 4, at least a part of the switch switching sliding contact surface provided in the changeover switch member and at least a part of the switch switching sliding contact surface provided in the on / off switching member have the same curvature. Therefore, the contact area between the switch-switching sliding contact surfaces can be reliably increased in the process in which the change-over switch member moves from the on position to the off position.

[Invention of claim 5]
According to the invention of claim 5, when the changeover switch member is disposed at the on position, the center of the circle partially including the arc shape of the switch changeover sliding surface is separated from the turning center of the turning operation member. By being in the position, the on / off switching member can easily come into contact with the switching switch member when the rotation operation member is rotated toward the rotation start position from the state where the changeover switch member is disposed at the on position. Further, as the changeover switch member is displaced to the OFF position, the changeover switch is brought about by the center of a circle partially including the arc shape of the switch changeover sliding surface approaching the vicinity of the rotation center of the rotation operation member. The force from the on / off switching member applied to the member can be released.

[Invention of claim 6]
According to the invention of claim 6, by operating the operation portion, the changeover switch member can be displaced between the on position and the off position without rotating the rotation operation member.

[Invention of Claim 7]
According to the seventh aspect of the present invention, when the rotation operation member is not rotated, the rotation operation member can always be positioned at the rotation start point, and the game ball launching device can be stopped. In addition, since the rotation operation member is rotated against the urging force that urges the rotation start point, the player can feel that the rotation operation member is being operated.

Here, when a period from when the movable door 15T is opened until it is closed is referred to as a “round”, in one round, the opening time of the movable door 15T has reached 29 seconds, or The process ends when any of the 10 game balls has been won or the condition is satisfied first.

  A continuous winning opening and a counting winning opening are provided inside the big winning opening 15, and the continuous winning opening and the counting winning opening are opened. More specifically, when the movable door 15T is opened, the continuous winning opening is opened, and after winning the continuous winning opening, the solenoid 15M (see FIG. 3) is driven to close the continuous winning opening. The counting prize opening will remain open. Then, when the specific area sensor 32 (see FIG. 3) provided in the continuation winning opening detects the winning of the game ball, a continuation right is generated, and the above-described end condition (the opening time of the movable door 15T has reached 29 seconds). (Or 10 game balls won in the big winning opening 15) and the round is completed, the next round is continuously executed. When the count sensor 33 (see FIG. 3) provided in the counting prize opening detects the winning of the game ball, the winning balls to the big prize opening 15 are counted together with the winning balls to the continuous prize opening. As described above, it is checked whether or not a total of 10 has been reached.

  The display device 13 is formed by assembling a liquid crystal module (not shown) (specifically, a TFT-LCD module) on the rear end surface of the display frame 23 having a frame structure as a whole. A front portion of the liquid crystal module surrounded by the display frame 23 is a liquid crystal display unit 34, and the player can view an image displayed on the liquid crystal display unit 34 through the display frame 23.

  As shown in FIG. 1, three special symbols 13A, 13B, and 13C for left, middle, and right are normally displayed side by side on the liquid crystal display unit 34. Each of these special symbols 13A, 13B, and 13C is composed of, for example, a plurality of types that express numbers from “0” to “11”. Usually, each special symbol 13A, 13B, and 13C has a predetermined value. Different types are confirmed and displayed on the liquid crystal display unit 34. Then, it is determined whether or not the game ball is won at the start winning opening 14, each special symbol 13A, 13B, 13C is scrolled up and down and displayed in a variably displayed state, for example, left, middle, right Each special symbol 13A, 13B, 13C is stopped and displayed in order. At this time, for example, when the result of the determination is successful and all the special symbols 13A, 13B, and 13C are the same symbol, that is, when they are all over, the game is in a “hit state” and the movable door 15T is opened. It is.

  A normal symbol display region 24 is provided in the lower left corner of the display region of the special symbols 13A, 13B, and 13C in the liquid crystal display unit 34. This normal symbol display area 24 is determined to be true or false when a gate switch 30 (see FIG. 3) provided in the start gate 18 detects the passage of a game ball, for example, a number from “0” to “9”. Is variably displayed over a predetermined period, and then a predetermined number is fixedly displayed. Then, for example, when the displayed number is an odd number, the movable wing pieces 14C, 14C provided at the start winning opening 14 are tilted sideways over a predetermined period (for example, 0.4 seconds). The symbols displayed in the normal symbol display area 24 are not limited to numbers but may be alphabets or symbols.

  As shown in FIG. 2, various control boards are provided on the rear surface of the pachinko gaming machine. Specifically, a main control board 50 is provided in the center of the rear surface of the pachinko gaming machine, and a lamp control board 55, an audio control board 56, and a display control board 57 are provided so as to overlap the main control board 50. ing. Further, a power supply board 58 and a payout control board 59 are provided below each of the boards 50, 55, 56, 57, and a game ball launcher (hereinafter simply referred to as “launcher”) 70 and A launch control board 60 is provided.

  As shown in FIG. 3, the main control board 50 includes, as a main part, a one-chip microcomputer 51 in which a CPU 51A, a RAM 51B, and a ROM 51C are packaged together.

  The one-chip microcomputer 51 receives signals from the above-described switch for detecting a winning ball and the sensors 31 to 33 via the input / output circuits 54 and 54, as well as the lamp control board 55, the sound control board 56, and the display control. Control signals are output to the substrate 57, the payout control substrate 59, the firing control substrate 60, and the like to control each part.

  The lamp control board 55 selects a light emission pattern and sets light emission data based on a control signal from the main control board 50, and causes the side lamps 22 and 22, the decorative lamp 35, LEDs, and the like to emit light.

  The sound control board 56 sets sound data for BGM and production based on the control signal from the main control board 50, and generates sound from the speaker 56S.

  The display control board 57 includes a display ROM 63 that stores control data, image data, and the like for displaying game images on the liquid crystal display unit 34. Then, based on the control signal from the main control board 50, the display CPU 61 extracts predetermined data from the display ROM 63, and a game image (special symbol, effect symbol, background image, character image) in the work area of the display RAM 62. , Character images, etc.) are created and displayed on the liquid crystal display unit 34.

  The payout control board 59 is based on a signal from the one-chip microcomputer 51 based on the winning of a game ball to each winning opening 14, 15, 20, 21 and a signal from the prepaid card unit 150 based on the winning ball payout device 52. And the ball lending device 53 is driven to pay out the game ball to the upper plate 27A.

  The launch control board 60 drives the launch device 70 based on the signal received from the one-chip microcomputer 51, and launches the game ball toward the game area R1. Specifically, the launch control board 60 includes control circuits 60A to 60C for the driving device, launch switch, and contact detection (see FIG. 4).

  The contact detection control circuit 60C detects a voltage level change caused by the player touching the operation knob 28 (specifically, a rotation operation member 81 described later), and whether or not the player touches the operation knob 28. Determine whether.

  The firing changeover switch control circuit 60B determines whether a later-described firing changeover switch 100 provided in the operation knob 28 is in an on state or an off state.

  The drive device control circuit 60A drives the firing device 70 (specifically, the firing motor 68) based on the determination results by the contact detection control circuit 60C and the firing changeover switch control circuit 60B. That is, when it is determined that the player is touching the operation knob 28 by the contact detection control circuit 60C and the firing switch 100 is determined to be on by the firing switch control circuit 60B, the launching device 70 is driven to fire a game ball.

  On the other hand, if it is determined by the contact detection control circuit 60C that the player is not touching the operation knob 28, or if the firing switch 100 is determined to be off by the firing switch control circuit 60B, the firing is performed. The device 70 is stopped and the launch of the game ball is prohibited.

  By the way, the launching device 70 has the following configuration. That is, as shown in FIG. 5, various components such as a firing motor 68 and a striking rod 67 are assembled to the base plate 65.

  As shown in FIG. 7, a striking rod 67 is disposed on the rear surface side of the base plate 65. The striking rod 67 has a structure in which a striking portion 67S protrudes from the tip of a substantially strip-shaped main body, and a striking coil spring is fixed to the striking portion 67S. As shown in FIG. 6, the striking portion 67S faces a striking window 78W formed on the firing rail 78, and a rotary shaft 69 having one end fixed near the base end of the striking rod 67 is supported by a bearing (not shown). By being pivotally supported by the base plate 65, the striking rod 67 rotates, and the striking portion 67S advances and retreats to the striking window 78W.

  A firing motor 68 having a cylindrical shape is disposed on the rear surface of the base plate 65 on the side of the striking rod 67, and stoppers 77 and 77 are provided on the upper and lower positions with the rotation shaft 69 interposed therebetween. ing. The stoppers 77 and 77 prevent the striking rod 67 from rotating too far forward (clockwise in FIG. 7).

  Further, a substrate storage case 42 is attached to the rear surface of the base plate 65 so as to cover the striking rod 67, the firing motor 68, and the stoppers 77, 77 from the rear side. The board storage case 42 has a flat box shape as shown in FIG. 5, and a launch control board 60 that drives and controls the launch motor 68 is housed therein.

  As shown in FIG. 5, a resilient element 66 </ b> E through which the rotation shaft 69 passes is attached to the front surface of the base plate 65. The elastic element 66E includes a torsion spring 66 sandwiched between a rotating ring 74 laid on the front surface of the base plate 65 and a cylindrical cap 64 fixed to the tip of the rotating shaft 69. The torsion spring 66 is wound around a cylindrical portion (not shown) extending from the cylindrical cap 64 or the rotating ring 74. One end of the torsion spring 66 is locked to the cylindrical cap 64 and the other end is locked to the rotating ring 74.

  The rotation ring 74 is rotatable with respect to the rotation shaft 69, and a gear 74G (see FIG. 6) is formed on the peripheral surface of the rotation ring 74. When the operation knob 28 is mounted on the operation knob mounting portion 28T fixed to the front surface of the base plate 65 (state shown in FIG. 5), the operation is performed by the gear mechanism including the rack gear 75 and the idle gear 76 shown in FIG. The knob 28 and the rotation ring 74 are connected, and the rotation ring 74 rotates according to the rotation operation of the operation knob 28. As a result, the position of one end of the torsion spring 66 can be changed.

  A torque arm 71 projects from the cylindrical cap 64 toward the operation knob mounting portion 28T, and a sliding boss 71B projects from the tip of the torque arm 71 toward the base plate 65. Then, the rotary plate 72 provided between the resilient element 66E and the operation knob mounting portion 28T in the base plate 65 slides with the sliding boss 71B. Specifically, the rotating disk 72 has a cam 72B integrally formed on the front surface of the gear 72A, and is rotatably attached to the base plate 65. Further, the rotation shaft of the firing motor 68 fixed to the rear surface of the base plate 65 protrudes in the vicinity of the gear 72 </ b> A on the front surface of the base plate 65, and the small gear 73 fixed to the rotation shaft of the firing motor 68 is provided. And meshed with the gear 72A (see FIG. 6). Then, by driving the firing motor 68, the entire turntable 72 is rotated in one direction.

  The cam 72B is semicircularly distributed in the gear 72A. When the rotating plate 72 rotates, the curved surface of the cam 72B and the sliding boss 71B of the torque arm 71 are in sliding contact with the torsion spring 66. In contrast, the cylindrical cap 64 is rotated in one direction. When the curved surface of the cam 72B passes through the sliding boss 71B, the cylindrical cap 64 rotates at once in the reverse direction by the elastic force of the torsion spring 66. As a result, the hitting bar 67 reciprocates together with the cylindrical cap 64, the game ball set on the firing rail 78 and the hitting bar 67 collide at the hitting window 78W, and the game ball is ejected toward the game area R1. It is.

  Note that the firing motor 68 of the present embodiment is configured to rotate 100 times per minute. That is, it is possible to launch 100 game balls per minute. Further, the initial twisting amount of the torsion spring 66 is changed by shifting the locking position between the rotation ring 74 of the resilient element 66E and the torsion spring 66 in the circumferential direction of the rotation ring 74, thereby adjusting the firing strength. It is good also as a possible structure.

  An operation knob 28 is attached to the front surface of the base plate 65. Specifically, the operation knob 28 is attached to an operation knob mounting portion 28T fixed to the base plate 65, and a decorative member 80, a rotation operation member 81, and a fixing member 82 are assembled to each other. Of these members 80, 81, 82, the rotation operation member 81 is rotatable with respect to the decorative member 80 and the fixing member 82. As the rotation angle of the rotation operation member 81 increases, the torsion amount of the torsion spring 66 provided in the bullet element 66E increases, and the launch strength of the game ball increases. That is, by turning the turning operation member 81, the game ball can be launched toward the game area R1 at an arbitrary momentum.

Each member 80-82 which comprises the operation knob 28 is explained in full detail.
As shown in FIG. 8, a decorative member 80 is provided at the front end of the operation knob 28. As shown in FIG. 9, the decorative member 80 has a hemispherical shape, and a cell board on which, for example, a character design or a character is drawn is housed in a visible manner.

  As shown in FIG. 8, a rotating operation member 81 is provided on the rear side of the decorative member 80. The rotation operation member 81 is formed by projecting, for example, four locking claws 85 a to 85 d for locking a player's finger on the peripheral surface of the base portion 84. The entire surface of the rotating operation member 81 is plated with metal.

  As shown in FIG. 9, the base portion 84 includes an inner configuration portion 84B having a substantially disc shape smaller than the outer configuration portion 84A inside the outer configuration portion 84A having a flat cylindrical shape, and these outer configuration portions. 84A and the inner structure part 84B are connected by two ribs 84C and 84C. Thereby, arc-shaped openings 87 and 87 are formed between the outer component portion 84A and the inner component portion 84B.

  One end of a ground wire 97 (see FIG. 5) is connected to the front surface side of the inner constituent portion 84B. The ground wire 97 is drawn rearward from an opening 88 formed in the inner constituent portion 84B and connected to the launch control board 60. Due to the ground wire 97, a weak current flows through the launch control board 60 when the player touches the rotation operation member 81, and the voltage level at the launch control board 60 changes. As described above, the firing control board 60 drives the firing device 70 (specifically, the firing motor 68) based on the change in the voltage level.

  A shaft hole 86 is formed through the center of the inner constituent portion 84B, and one end of a rotating shaft 79 (corresponding to the “shaft portion” of the present invention) is inserted into and fixed to the shaft hole 86. The other end of the rotating shaft 79 is gear-coupled to the elastic element 66E at the operation knob mounting portion 28T. The rotation operation member 81 is always urged in the direction indicated by the thick arrow in FIGS. 11 and 13 by the urging force of the torsion spring 66 (see FIG. 5), and the rotation start point It is stopped at the position (the state shown in FIGS. 11 and 13).

  In addition, from the peripheral part of the axial hole 86, the cylindrical boss 95 protruding toward the front and rear of the inner component part 84B stands, and as shown in FIG. A plurality of ribs 96 are erected so as to connect the outer peripheral surface of the cylindrical boss 95 and the peripheral wall 84S erected rearward from the peripheral edge of the inner component part 84B.

  The locking claws 85a to 85d formed to protrude from the base portion 84 are as follows. That is, the locking claws 85a to 85d have a mountain shape as a whole. Each of the locking claws 85a to 85d is a portion in which the portion facing the urging direction of the rotation operation member 81 (the direction indicated by the thick arrow in FIGS. 11 and 13) faces the opposite side of the urging direction. The slope is steeper than.

  The locking claws 85a to 85d are arranged in the direction opposite to the urging direction of the rotation operation member 81 in the first locking claw 85a, the second locking claw 85b, the third locking claw 85c, and the fourth locking claw. They are arranged at almost equal intervals in the order of 85d. And the 4th latching claw 85d is arranged in the position about 180 degrees away from the 1st latching claw 85a. As shown in FIG. 10, a space 93 having a size corresponding to one game ball is provided on the rear side of the largest first locking claw 85a among the locking claws 85a to 85d. It should be noted that an insertion prohibition member 99 is detachably provided in the space 93 as shown in FIG. 17, so that it is possible to arbitrarily select a state where the insertion of the game ball into the space 93 is prohibited and an allowable state. Good.

  By the way, a rotating wall 110 corresponding to the “on / off switching member” of the present invention is provided on the rear surface of the rotating operation member 81. As shown in FIG. 10, the rotating wall 110 is a belt that stands rearward from the rear surface of the inner component portion 84B (front side in FIG. 10) and is curved in an arc along the peripheral wall 84S of the inner component portion 84B. It has a plate shape.

  Further, the rotating wall 110 is provided at a substantially intermediate position between the first locking claw 85a and the fourth locking claw 85d on the rear surface of the inner component portion 84B. That is, as shown in FIG. 11, in the urging direction of the rotation operation member 81 (the direction indicated by the thick arrow in FIG. 11), the front side (the urging direction side) of the first locking claw 85a and the first It is provided at a position on the rear side (opposite direction to the urging direction) from the four locking claws 85d.

  More specifically, as shown in FIG. 11, the rotation wall 110 has a biasing direction of the rotation operation member 81 with respect to a horizontal line H passing through the rotation center G of the rotation operation member 81 at the rotation start point position. Extends from the position shifted by about 30 ° toward the position just below the rotation center G to about 60 °.

  Here, 110 A of outward faces which faced the radial direction outer side of the base part 84 (rotation operation member 81) among the rotation walls 110 (it corresponds to the "sliding contact part" of this invention, and a "switch switching sliding contact surface"). Form an arc surface substantially along a circle drawn with the rotation center G as a center point. In other words, the outward surface 110 </ b> A extends substantially along the rotatable direction around the rotation shaft 79 of the rotation operation member 81.

  Specifically, the arcuate surface constituting the outward surface 110A of the rotating wall 110 increases from the rear end portion toward the front end portion in the biasing direction of the rotating operation member 81 (the direction indicated by the thick arrow in FIG. 11). It is curved so that it slightly approaches the rotation center G. In other words, the curvature of the arc surface constituting the outward surface 110A gradually increases from the rear end portion to the front end portion in the biasing direction of the rotation operation member 81.

  Specifically, of the outward surface 110A, the radius R2 of the arc surface constituting the rear end portion in the urging direction of the rotation operation member 81 (the direction indicated by the thick arrow in FIG. 11) is, for example, 17. The radius R3 of the arc surface constituting the front end portion is 3 mm (curvature = 1 / 17.3), for example, 15 mm (curvature = 1/15). The wall thickness M2 of the rotating wall 110 is uniform throughout, for example, 1.8 mm. Further, both end edges of the rotating wall 110 are chamfered.

  The above is the description of the rotation operation member 81. Next, the fixing member 82 will be described. As shown in FIG. 8, the fixing member 82 is provided on the rear side of the rotation operation member 81. As shown in FIG. 9, the fixing member 82 has a substantially cylindrical shape, and a rotation shaft 79 fixed to the rotation operation member 81 is inserted into a shaft hole 89 formed through the center portion. Thereby, the rotation operation member 81 can rotate with respect to the fixed member 82 around the rotation shaft 79.

  The front end portion of the fixing member 82 is formed with a large-diameter portion 82A that opens forward (on the side of the rotation operation member 81). Three support columns 83 are formed inside the large diameter portion 82A. That is, in the large-diameter portion 82 </ b> A, two support columns 83, 83 stand side by side from a position above the shaft hole 89, and one support column 83 stands from a position directly below the shaft hole 89. And these three support pillar 83 protrudes ahead rather than the front-end edge of 82 A of large diameter parts.

  When the rotation operation member 81 is assembled to the front end portion of the fixing member 82, the outer component portion 84A of the rotation operation member 81 is disposed outside the front end portion of the large diameter portion 82A, and as shown in FIG. The support column 83 enters the openings 87 and 87 formed in the moving operation member 81. That is, in the rotation operation member 81, two support columns 83, 83 provided above the shaft hole 89 enter the opening 87 positioned on the upper side at the rotation start point position (state of FIG. 13). Then, one support pillar 83 provided at a position below the shaft hole 89 enters the opening 87 located on the lower side. When the rotation operation member 81 is rotated with respect to the fixed member 82 in this state, the position of the support column 83 in the openings 87 and 87 is displaced (see FIGS. 14 to 16). And in the rotation start point position (the state of FIG. 13 and FIG. 14A) and the rotation end point position (the state of FIG. 16B), it was formed in the peripheral surface of the support pillar 83 and the base part 84. The rib 84C comes into contact with the rotation operation member 81 and cannot be rotated any more. In the present embodiment, the rotation start point position of the rotation operation member 81 (the state shown in FIGS. 13 and 14 (A)) and the rotation end point position (the state shown in FIG. 16) are separated by about 100 °. Yes. That is, the rotatable range of the turning operation member 81 is about 100 ° from the turning start position.

  When the rear surface of the decorative member 80 is abutted against the front end portion of the support column 83 penetrating the rotation operation member 81 and the fixing member 82 and the decoration member 80 are fixed, the rotation operation member 81 is fixed to the fixing member 82 and the decoration member 80. The decoration member 80, the rotation operation member 81, and the fixing member 82 are assembled together in a state where the decoration member 80, the rotation operation member 81, and the fixing member 82 are pivotally supported.

  By the way, the firing changeover switch 100 is accommodated in the inner space of the large-diameter portion 82A of the fixed member 82. As shown in FIG. 9, the firing changeover switch 100 includes a switch body 101 and a switch operation member 102 corresponding to the “switching switch member” of the present invention, and allows the launching device 70 to launch a game ball. The on state is switched to the off state in which the launch of the game ball is prohibited.

  The switch body 101 has a rectangular parallelepiped shape as a whole. A plurality of connection terminals 103 for wiring 98 (see FIG. 5) for connecting the switch body 101 and the launch control board 60 are provided on the side face of the switch body 101 facing the center side of the large diameter portion 82A. Yes. In addition, a push button 104 that protrudes to the side is provided on the side surface (the surface facing the outside of the large-diameter portion 82A) on the opposite side to the side surface on which the connection terminal 103 is provided. The push button 104 is urged in a direction protruding from the side surface of the switch body 101 (on state). When the push button 104 is pressed toward the switch body 101, the firing switch 100 is turned off. The launch of the game ball is stopped.

  Support holes 105 </ b> A and 105 </ b> B are penetratingly formed at two locations on the top and bottom of the switch body 101. A support pin 90 erected from the large-diameter portion 82A of the fixing member 82 is inserted into the lower support hole 105B. Further, a screw (not shown) is passed through the upper support hole 105 </ b> A from the front side of the switch body 101, and this screw is screwed into a screw hole 91 formed in the fixing member 82. Thus, the switch body 101 is positioned and fixed at a predetermined position inside the fixing member 82.

  On the other hand, the resin-made switch operation member 102 has a substantially L shape as a whole, and is provided in the vicinity of the switch body 101 in the fixed member 82. As shown in FIG. 12, the switch operation member 102 has a structure in which a pressing portion 107 is extended from a flat base portion 102 </ b> A. And it can rotate centering | focusing on the circular hole 106 penetrated and formed in 102 A of bases. In other words, the cylindrical shaft 92 erected from the fixing member 82 is inserted into the circular hole 106, and a screw inserted from the front side of the base 102 </ b> A is screwed into the cylindrical shaft 92, so that the switch operating member 102 is connected to the switch body 101. Is pivotally supported around the cylindrical shaft 92 at a position near the center of the shaft.

  Of the switch operation member 102, the pressing portion 107 is disposed on the side of the switch body 101 on the side where the push button 104 is provided, as shown in FIG. The pressing portion 107 extends along the side surface of the push button 104, and the pressing surface 107A facing the switch body 101 forms a flat surface, while the surface opposite to the pressing surface 107A is the inner periphery of the fixing member 82. An arc surface is formed along the surface. At the tip of the pressing portion 107, a protruding portion 108 that protrudes to the surface opposite to the pressing surface 107A and bulges in the front-rear direction is formed (see FIG. 9). The protruding portion 108 protrudes to the outside of the fixing member 82 from a notch 82B (see FIG. 9) formed in a part of the peripheral surface of the large diameter portion 82A of the fixing member 82. When the protruding portion 108 is pressed toward the peripheral surface of the fixing member 82, the switch operating member 102 rotates around the cylindrical shaft 92, and the push button 104 of the switch body 101 is pressed by the pressing surface 107A of the pressing portion 107. The Thereby, the launch switch 100 is turned off, and the launch of the game ball by the launch device 70 is stopped. That is, the firing changeover switch 100 can be switched on and off from the outside of the operation knob 28. Of the switch operation member 102, the protruding portion 108 corresponds to the “operation portion” of the present invention. In addition, the position of the switch operating member 102 in a state where the push button 104 is pressed by the pressing portion 107 (the firing changeover switch 100 is in the off state) corresponds to the “off position” in the present invention, and the pressing portion 107 pushes the push button 104. The position of the switch operation member 102 in a state where the switch is not pressed (the firing changeover switch 100 is in the on state) corresponds to the “on position” in the present invention.

  Of the peripheral surface of the large-diameter portion 82A, the portion that overlaps the first locking claw 85a when the rotation operation member 81 is at the rotation start point position with respect to the fixed member 82 is a substantially flat surface. Yes. As a result, when the rotation operation member 81 reaches the rotation start position, the game ball can be inserted into the space 93 formed on the rear surface of the first locking claw 85a. Then, when the turning operation member 81 is turned while the game ball is inserted into the space 93, the turning operation member 81 becomes a fixed member 82 due to friction between the game ball and the outer peripheral surface of the large-diameter portion 82 </ b> A of the fixing member 82. It becomes possible to hold | maintain in the state rotated with respect to it.

  A receiving wall 109 (corresponding to the “sliding contact portion” of the present invention) is formed in a portion of the base portion 102A of the switch operation member 102 that is farther from the pressing portion 107 than the circular hole 106. As shown in FIG. 9, the receiving wall 109 has a rectangular plate shape as a whole. The receiving wall 109 has a shape projecting forward from the upper edge portion of the base portion 102 </ b> A of the switch operation member 102. In other words, the receiving wall 109 is erected at a right angle from the front surface of the base portion 102A (the front surface in FIG. 12).

  Of the receiving wall 109, the inward surface 109 </ b> A (the “switch-switching sliding contact surface” of the present invention) facing the rotation shaft 79 (the rotation center G in FIGS. 14 to 16) of the rotation operation member 81 in FIG. 13. (Corresponding) is curved in an arc shape so as to correspond to the curvature of the outward face 110A of the rotating wall 110. Specifically, as shown in FIG. 12, the radius R1 of the circle including the inward surface 109A of the receiving wall 109 is, for example, 16.6 mm. That is, the curvature (= 1 / 166.6) of the inward surface 109A is an arc surface (radius R3 = 15 mm) constituting the front end portion in the biasing direction of the rotation operation member 81 in the outward surface 110A of the rotation wall 110. ) And is larger than the curvature of the arc surface (radius R2 = 17.3 mm) constituting the rear end portion. The wall thickness M1 of the receiving wall 109 is 2 mm, for example.

  When the switch operating member 102 is attached to the fixing member 82, the front end edge of the receiving wall 109 and the front end edge of the fixing member 82 are substantially flush with each other. When the rotation operation member 81 is attached to the front end portion of the fixing member 82 as described above, as shown in FIG. 13, the rotation wall 110 protruding rearward of the rotation operation member 81 and the switch The receiving wall 109 projecting forward from the operation member 102 is disposed on the same plane (surface parallel to the paper surface in FIG. 13) orthogonal to the rotating shaft 79, and the rotating wall 110 is more than the receiving wall 109. It arrange | positions at the rotation axis | shaft 79 (rotation center G in FIGS. 14-16) side.

  As described above, the curvature of the front end portion in the biasing direction of the rotation operation member 81 in the outward surface 110A of the rotation wall 110 is made larger (curved greatly) than the curvature of the inward surface 109A of the switch operation member 102. ), The rotation operation member 81 is rotated from the state where the switch operation member 102 is in the “off position” (the state where the receiving wall 109 and the rotation wall 110 are separated) toward the rotation start point position, When the rotating wall 110 comes into contact with the receiving wall 109, it is possible to prevent a sudden force from the rotating wall 110 against the receiving wall 109. This is because at least a part of the rotating wall 110 in contact with the receiving wall 109 is displaced on the receiving wall 109 while always releasing the force so that the force does not concentrate on a specific part of the receiving wall 109 (with the receiving wall 109 and This is because the contact portion with the rotating wall 110 is displaced).

  In addition, the curvature of the rear end portion of the outward surface 110A of the rotation wall 110 in the direction opposite to the biasing direction of the rotation operation member 81 is made smaller than the curvature of the inward surface 109A of the switch operation member 102 (smallly curved). By doing so, the switch operation member 102 can be held at the OFF position when the rotation operation member 81 approaches the rotation start point position. In addition, since the rotating wall 110 and the receiving wall 109 are in sliding contact with each other, it is possible to prevent the receiving wall 109 from being subjected to excessive force while maintaining the contact force of the rotating wall 110 with the receiving wall 109. .

  Further, since the length of the arc constituting the outward surface 110A of the rotating wall 110 is longer than the length of the arc constituting the inward surface 109A of the receiving wall 109, for example, the length of the arc constituting the outward surface 110A is The contact time between the switch operation member 102 and the rotation operation member 81 can be increased and the switch operation member 102 can be made longer than when the length of the arc constituting the inward surface 109A of the receiving wall 109 is made shorter. It is possible to provide a so-called “play” between the time when the position is switched to the OFF position and the time when the rotation start position is reached. As described above, it is preferable that the length of the arc constituting the outward surface 110A is longer than the length of the arc constituting the inward surface 109A, but the length of the arc constituting the outward surface 110A is the arc constituting the inward surface 109A. The length may be shorter or the same length.

  Here, for example, as shown in FIG. 16, when the rotation wall 110 provided in the rotation operation member 81 and the receiving wall 109 provided in the switch operation member 102 are separated from each other, that is, the firing changeover switch 100 is In the ON state (the switch operation member 102 is “ON position”), the inward surface 109A of the receiving wall 109 is rotated by the rotation trajectory Q1 of the outward surface 110A of the rotation wall 110 provided in the rotation operation member 81 (in other words, The circle Q2 including the inward surface 109A of the receiving wall 109 is at an acute angle with respect to the rotation trajectory Q1. Crossed. That is, the inward surface 109 </ b> A is arranged so as to be separated from the rotation locus Q <b> 1 as it goes to the front portion in the urging direction of the rotation operation member 81. As a result, the rotation operation member 81 is rotated in the urging direction (counterclockwise direction in FIG. 16) and returned to the rotation start point position (state (A) in FIG. 14). The outwardly facing surface 110A of the provided rotating wall 110 and the inwardly facing surface 109A of the receiving wall 109 formed on the switch operating member 102 come into contact with each other, and the receiving wall 109 is gradually pushed outward. That is, the receiving wall 109 is gradually tilted about the cylindrical shaft 92. As the receiving wall 109 is tilted, the position of the center point P of the circle Q2 including the inward surface 109A of the receiving wall 109 gradually changes.

  That is, as shown in FIG. 16, when the turning wall 110 and the receiving wall 109 are separated from each other, the center point of the turning locus Q1 of the outward surface 110A of the turning wall 110, that is, the turning operation member 81 Although the position of the rotation center G and the position of the center point P of the circle Q2 including the inward surface 109A of the receiving wall 109 are relatively large, the rotation operation member 81 is positioned at the rotation start point ((( When the inward surface 109A of the receiving wall 109 and the outward surface 110A of the rotating wall 110 come into contact with each other, the center point P of the circle Q2 including the inward surface 109A of the receiving wall 109 is It gradually moves so as to approach the rotation center G of the rotation operation member 81 (see FIGS. 14 to 15).

  Further, the inward surface 109 </ b> A of the receiving wall 109 is pushed outward by the outward surface 110 </ b> A of the rotating wall 110, and the switch operating member 102 rotates about the cylindrical shaft 92, so that it is provided on the opposite side of the receiving wall 109. The pressed portion 107 thus moved moves closer to the push button 104 side of the switch body 101. Then, as shown in FIG. 14B, when the rotation operation member 81 approaches (closes to) the rotation start point position, the pressing surface 107 </ b> A of the pressing unit 107 presses the push button 104. As a result, the firing changeover switch 100 is turned off (the switch operation member 102 is in the “off position”). That is, if the rotation operation member 81 is brought close to the rotation start point position (the state shown in FIG. 14A), the firing changeover switch 100 is turned off without pressing the protrusion 108 of the switch operation member 102. The launching of the game ball by the launching device 70 is stopped.

  Thus, since the firing changeover switch 100 is turned off at the time when the turning operation member 81 approaches the turning start point position (immediately before reaching the turning start point position), the turning operation member 81 is turned on by the firing changeover switch. Further rotation is possible until the rotation start point position is reached after 100 is turned off. Here, even if the rotation operation member 81 is further rotated toward the rotation start point position after the firing changeover switch 100 is turned off, the switch operation member 102 and the rotation operation member 81 are in contact with each other. Since the part (the inward surface 109 of the receiving wall 109 and the outward surface 110A of the rotating wall 110) are in sliding contact, the force applied to the firing changeover switch 100 (more specifically, the receiving wall 109 of the switch operating member 102) increases. You can get away with it.

  Here, the edge of the receiving wall 109 on the side close to the circular hole 106, in other words, the receiving end formed in the rear end portion in the urging direction (counterclockwise direction in FIG. 14) of the rotation operation member 81. The upper surface of the wall rear end portion 109E (see FIG. 12) obliquely intersects the inward surface 109A of the receiving wall 109, and the receiving wall 109 and the rotating wall 110 are separated (state shown in FIG. 16). ) At an angle with respect to the rotation trajectory Q1 of the outward surface 110A of the rotation wall 110. When the rotation operation member 81 is rotated in the urging direction by the receiving wall rear end portion 109E, the edge of the rotation wall 110 and the edge of the reception wall 109 abut against each other so that the rotation operation member 81 is Stopping on the way is prevented, and the rotating wall 110 can be smoothly guided toward the inward surface 109 </ b> A of the receiving wall 109.

The above is the description of the configuration of the pachinko gaming machine, and the operation and effect of the pachinko gaming machine of this embodiment will be described below.
In a pachinko machine, when starting a game, the operation knob 28 is operated to fire a game ball. That is, when the turning operation member 81 provided in the operation knob 28 is turned clockwise from the turning start position (the state shown in FIG. 14A), the game is played with the firing strength corresponding to the turning angle. The ball is thrown into the game area R1. The game ball that has reached the game area R1 flows downward while coming into contact with the lamp windmill 17, the windmill 19, the display frame body 23, the obstacle nail, and the like provided in the game area R1. 15, 20, 21 or moves into the ball receiving port 16.

  By the way, when the player does not touch the operation knob 28, the rotation operation member 81 is urged counterclockwise in FIG. 14 by the urging force of the torsion spring 66 provided in the launching device 70. The rotation starting point position shown in A) is held. When the rotation operation member 81 is at the rotation start point position, the rotation wall 110 provided in the rotation operation member 81 and the receiving wall 109 of the switch operation member 102 provided in the firing changeover switch 100 overlap each other and rotate. At least a part of the outward surface 110A of the wall 110 and the inward surface 109A of the receiving wall 109 are in contact with each other.

  At this time, since the receiving wall 109 is pressed outward by the rotating wall 110, the switch operation member 102 is rotated around the cylindrical shaft 92 in the clockwise direction in FIG. 14, and the pressing surface 107 A of the pressing portion 107 is moved. The push button 104 of the switch body 101 is pressed. That is, the launch switch 100 is turned off, and the launch of the game ball is stopped.

  When the rotation operation member 81 is rotated more than a predetermined angle against the urging force of the torsion spring 66, for example, as shown in FIG. The receiving wall 109 provided in the switch 100 is separated. Then, the pressing force from the rotating wall 110 is not applied to the receiving wall 109 of the switch operation member 102, and the pressing force from the pressing portion 107 is not applied to the push button 104. That is, the push button 104 provided in the switch body 101 is in a state of protruding outward from the side surface of the switch body 101 by its own urging force. Thereby, the launch switch 100 is turned on, and a game ball is launched from the launch device 70. At this time, the protruding portion 108 formed at the distal end portion of the switch operation member 102 is in a state of protruding from the notch 82B, and pressing the protruding portion 108 causes the rotation operation member 81 to be more than a predetermined angle. The firing changeover switch 100 can be turned off while being rotated. As a result, the player can launch or stop the game ball at an arbitrary timing.

  Now, when the player releases his / her hand from the operation knob 28 in a state where the rotation operation member 81 is rotated (for example, in the state shown in FIG. 16), the operation is as follows. That is, the rotation operation member 81 is rotated toward the rotation start point position shown in FIG. 14A (counterclockwise in FIG. 16) by the urging force of the torsion spring 66.

  First, as shown in FIG. 15B, the front end portion of the rotating wall 110 in the urging direction of the rotating operation member 81 is the urging direction of the rotating operation member 81 in the receiving wall 109 ( It contacts the upper surface of the receiving wall rear end portion 109E of the rear end portion (counterclockwise direction in FIG. 15). Then, the receiving wall 109 is slightly pushed outward, and the switch operation member 102 rotates slightly clockwise about the cylindrical shaft 92. Then, the pressing surface 107 </ b> A of the pressing portion 107 contacts the push button 104 of the switch body 101. At this time, the inward surface 109A of the receiving wall 109 still intersects the rotation trajectory Q1 of the outward surface 110A of the rotation wall 110 at an acute angle, but the angle becomes slightly smaller. Then, as the switch operating member 102 rotates, the position of the center point P of the circle Q2 including the inward surface 109A of the receiving wall 109 is closer to the rotation locus Q1 of the rotating wall 110 than the state shown in FIG. It slightly approaches the position of the center point (rotation center G).

  When the rotation operation member 81 is further rotated in the urging direction (counterclockwise direction in FIG. 15), the outward surface 110A of the rotation wall 110 moves while sliding on the inward surface 109A of the receiving wall 109, Of the outward face 110A of the rotating wall 110, the front part in the biasing direction and the rear part in the biasing direction of the inward face 109A of the receiving wall 109 are in contact (state (A) in FIG. 15). Then, the receiving wall 109 is further pressed outward. As a result, the switch operation member 102 further rotates, and the pressing of the push button 104 by the pressing portion 107 is started. At this time, the crossing angle between the inward surface 109A of the receiving wall 109 and the rotation trajectory Q1 of the outward surface 110A of the rotating wall 110 becomes an acute angle. Then, the position of the center point P of the circle Q2 including the inward surface 109A of the receiving wall 109 is more than the center point (rotation center G) of the rotation trajectory Q1 of the rotation wall 110 than in the state shown in FIG. ). Note that the radius R3 (15 mm) of the arc surface of the front end portion in the biasing direction of the outward surface 110A of the rotating wall 110 is the radius R1 (16.6 mm) of the arc surface constituting the inward surface 109A of the receiving wall 109. Since these are slightly different, at this time (the state shown in FIG. 15A), the inward surface 109A of the receiving wall 109 and the outward surface 110A of the rotating wall 110 are in point contact.

  That is, the contact portion between the rotation wall 110 and the receiving wall 109 is displaced according to the amount of rotation operation of the rotation operation member 81. Therefore, the contact force applied from the rotation operation member 81 to the switch operation member 102 does not concentrate on a specific part of the switch operation member 102 (specifically, the receiving wall 109), and the switch operation member 102 is turned off from the on position. It can be displaced to a position.

  When the rotation operation member 81 is further rotated in the urging direction (counterclockwise direction in FIG. 14), the outward surface 110A of the rotation wall 110 moves while being in sliding contact with the inward surface 109A of the receiving wall 109. The overlapping portion between the wall 109 and the rotating wall 110 gradually increases. Then, as shown in FIG. 14B, when the inward surface 109A of the receiving wall 109 overlaps with the outward surface 110A of the rotating wall 110, the receiving wall 109 is pushed further outward, and the switch operation is performed. The member 102 is rotated. That is, the pressing unit 107 is in the state where the push button 104 is most depressed (the switch operation member 102 is in the off position), and the firing switch 100 is in the off state. At this time, the inward surface 109A of the receiving wall 109 and the rotation locus Q1 of the outward surface 110A of the rotation wall 110 are substantially overlapped. The position of the center point P of the circle Q2 including the inward surface 109A of the receiving wall 109 is close to the position of the center point (rotation center G) of the rotation locus Q1 of the rotation wall 110.

  Here, as described above, the radius of the circular arc surface that forms the outward surface 110A of the rotating wall 110 gradually decreases from the front end portion toward the rear end portion in the urging direction of the rotating operation member 81. Yes. At this time (the state shown in FIG. 14B), the radius of the arc surface of the portion of the outward surface 110A in contact with the inward surface 109A is the radius R1 of the arc surface constituting the inward surface 109A of the receiving wall 109. Therefore, the inward surface 109 </ b> A of the receiving wall 109 and the outward surface 110 </ b> A of the rotating wall 110 are in surface contact (or the number of point contact parts is increased).

  When the rotation operation member 81 is further rotated in the urging direction (counterclockwise direction in FIG. 14), a portion of the outward surface 110A of the rotation wall 110 that contacts the inward surface 109A of the receiving wall 109 gradually increases. And the contact part is displaced to the rear end side in the urging direction of the rotation operation member 81. Then, the support column 83 provided in the fixing member 82 comes into contact with the edge (rib 84C) of the opening 87 of the rotation operation member 81, so that the rotation of the rotation operation member 81 in the urging direction is stopped. Then, the rotation operation member 81 is held at the rotation start point position (state (A) of FIG. 14). Then, the central portion of the outward surface 110A of the rotating wall 110 (the intermediate portion between the front end portion and the rear end portion in the urging direction of the rotating operation member 81) is in contact with the inward surface 109A of the receiving wall 109. The wall 109 is kept pushed to the outermost position. As a result, the pressing portion 107 of the switch operation member 102 is held in a state where the push button 104 is pushed in most.

  At this time, the inward surface 109A of the receiving wall 109 and the rotation trajectory Q1 of the outward surface 110A of the rotating wall 110 are still substantially overlapped. That is, the position where the center P of the circle Q2 including the inward surface 109A of the receiving wall 109 and the center of the rotation locus Q1 of the outward surface 110A of the rotation wall 110, that is, the rotation center G of the rotation operation member 81 are close. Is held in. Therefore, after the firing changeover switch 100 is turned off (the state shown in FIG. 14B), the inward surface 109A of the receiving wall 109 and the outward surface 110A of the rotating wall 110 are in surface contact (or point contact). It slides in a state where the part is increased.

  In other words, the outward surface 110A of the rotating wall 110 and the inward surface 109A of the receiving wall 109 are changed from point contact to surface contact in the process in which the rotation operation member 81 returns to the rotation start point position. The contact area gradually increases. Here, as the rotation operation member 81 approaches the rotation start point position (the amount of rotation in the biasing direction increases), the pressing force with which the rotation wall 110 pushes the receiving wall 109 outward increases. Since the area also increases with this, the pressing force can be dispersed. Therefore, the concentration of the pressing force on a specific part of the inward surface 109A of the receiving wall 109 is suppressed.

  Further, when the rotation operation member 81 is returned to the rotation start position, the switch operation member 102 is turned off from the on position while the rotation wall 110 of the rotation operation member 81 and the receiving wall 109 of the switch operation member 102 are in sliding contact. Since the position is switched to the position, when the rotation operation member 81 further rotates toward the rotation start point position after the switch operation member 102 is switched to the off position, the switch operation member 102 is required from the rotation operation member 81. No more power is applied. That is, after the switch operation member 102 is switched from the ON position to the OFF position, the rotation wall 110 and the receiving wall 109 of the switch operation member 102 remain in sliding contact with each other. It is possible to rotate 81 to the rotation start point position.

  As described above, according to the present embodiment, in the process in which the rotation operation member 81 is rotated from the rotated state to the rotation start point position (the firing changeover switch 100 is displaced from the on state to the off state), the rotation is performed. The outward surface 110A of the rotating wall 110 formed on the operation member 81 and the inward surface 109A of the receiving wall 109 provided in the firing changeover switch 100 are in sliding contact with each other, and the rotating wall 110 gradually pushes the receiving wall 109 outward. Thus, compared with a conventional ball game machine, the impact at the contact portion (the rotating wall 110 and the receiving wall 109) between the rotation operation member 81 and the firing changeover switch 100 is reduced. Further, after the switch operation member 102 is switched from the ON position to the OFF position, the rotation wall 110 of the rotation operation member 81 and the switch operation member 102 are received until the rotation operation member 81 reaches the rotation start point position. Since the state in which the wall 109 is in sliding contact continues, the load on the switch operation member 102 can be suppressed. Thereby, deterioration or breakage of the rotating wall 110 of the rotating operation member 81 and the receiving wall 109 of the firing changeover switch 100 can be prevented.

  Further, for example, in the conventional configuration shown in FIG. 18, when the rotation operation member 2 is returned to the rotation start position, the contact piece 4 provided on the rotation operation member 2 and the contact piece 4 of the firing changeover switch 3 are provided. Between the contact pieces 4 and 4 until the rotation operation member 2 reaches the rotation start position after the firing switch 3 is switched from the on state to the off state. For example, although the bent portions 5 and 6 of the firing changeover switch 3 may be broken, according to the present invention, the turning operation member 81 starts turning after the firing changeover switch 100 is switched from the on state to the off state. Until returning to the position, an extra force can be released, and deterioration or breakage of the bent portion of the switch operation member 102 of the firing changeover switch 100 can be prevented.

[Other Embodiments]
The present invention is not limited to the above-described embodiment. For example, the embodiments described below are also included in the technical scope of the present invention, and various other than the following can be made without departing from the scope of the invention. It can be changed and implemented.
(1) In the above embodiment, a pachinko gaming machine is illustrated as an example of a ball game machine, but the present invention may be applied to, for example, an arrangement ball as long as it is a ball game machine.

(2) In the above-described embodiment, the inward surface 109A of the receiving wall 109 provided in the firing changeover switch 100 and the outward surface 110A of the rotating wall 110 provided in the rotating operation member 81 have an arc shape. Any one of the inwardly facing surface 109A of 109 and the outwardly facing surface 110A of the rotating wall 110 may have an arc shape so that the inwardly facing surface 109A and the outwardly facing surface 110A can be in sliding contact with each other. For example, only the outward surface 110A may have an arc shape, and the inward surface 109A may have a flat surface.

(3) In the embodiment, the curvature of the outward surface 110A of the rotating wall 110 is configured to gradually increase from the rear end portion to the front end portion in the biasing direction of the rotating operation member 81. However, the curvature of the outward surface 110A may be constant.

(4) In the embodiment described above, the curvature of a part of the outward surface 110A of the rotating wall 110 is the same as the curvature of the inward surface 109A of the receiving wall 109, but the whole may have the same curvature. In this way, the inward surface 109A and the outward surface 110A are always in surface contact when the receiving wall 109 and the rotating wall 110 are in sliding contact with each other when the firing changeover switch 100 is displaced from the on state to the off state. That is, the contact area can be gradually increased immediately after contact between the rotating wall 110 and the receiving wall 109. Thereby, the pressing force from the rotating wall 110 applied to the receiving wall 109 can be dispersed immediately after the contact between the inwardly facing surface 109A and the outwardly facing surface 110A.
