Description

  The present invention relates to a gaming machine represented by a slot machine or the like.

  This type of gaming machine is configured to enjoy a game using coins (medals) that are gaming media, and usually a bet up to a preset number of coins in one game is used to play the gaming machine. When a predetermined winning combination is started, a predetermined number of coins are paid out. Gaming machines are usually set up to bet up to 3 coins in a single game, and a bet button for betting 1, 2, or 3 coins on a predetermined position on the front door of the gaming machine. Are provided.

  FIG. 10 is a diagram for explaining the configuration of a max bet button 101 provided in a conventional gaming machine. The max bet button 101 is configured to bet coins corresponding to the maximum bet number set in the gaming machine. For example, if no coin is bet at the start of the game, three coins can be bet. It is configured to be able to.

  The max bed button 101 is attached and fixed to the front door 111 by being received from an opening (not shown) formed at a predetermined position of the front door 111, and has a casing 103a on one side. 103, a sliding cover portion 105b that is loaded in the casing 103 and is capable of sliding in the casing 103 against the urging force of the shielding plate 105a and the coil spring 107, and a pressing cover body provided on the front end side of the sliding contact portion 105b A movable portion 105 having 105c, a coil spring 107 that exerts an urging force to return the movable portion 105 to the neutral position, a pair of light projecting portions 109a and a light receiving portion (not shown), and a shielding plate 105a of the movable portion 105 A photo interrupter 109 that outputs a predetermined signal by shielding between the light projecting unit 109a and the light receiving unit during the sliding contact process of the sliding contact unit 105b. It is provided.

  Further, at the opening end portion of the opening 103 a of the casing 103, when the max bed button 101 is accommodated in the opening of the front door 111, it is locked to a casing receiving portion 113 provided at the opening edge of the opening. The flange portion 103b protrudes outward. Further, at a position below the flange portion 103 b of the casing 103, the casing 103 is elastically deformed in a direction approaching the casing 103 in the process of accommodating the casing 103 in the opening of the front door 111, and is separated from the casing 103 after the casing 103 is accommodated. A pair of locking claws 103c that restore in the direction are provided.

  According to the max bet button 101 having the above-described configuration, when the max bet button 101 is pressed to start a game, when the press cover body 105c of the movable part 105 is pressed, the sliding contact part 105b of the movable part 105 is operated. Slidably contact the inner peripheral surface side of the casing 103 against the urging force of the coil spring 107 and moved downward, and the shielding plate 105a of the movable part 105 shields between the light projecting part 109a and the light receiving part of the photocoupler 109. . As a result, a predetermined signal is output from the photocoupler 109, and the operation of the max bet button 101 is detected. At this time, since the flange portion 103b of the casing 103 is locked to the casing receiving portion 113, it is possible to prevent the max bed button 101 from falling into the front door 111 due to the force exerted on the movable portion 105. .

  Further, when the max bet button 101 is accommodated, the pair of locking claws 103c are restored in a direction away from the casing 103. Therefore, when the max bet button 101 is removed, the upper end of the locking claw 103c is Since it contacts the back side of the front door 111, the Max bet button 101 cannot be removed easily.

  Further, since the max bet button 101 only needs to be accommodated in the opening portion of the front door 111 in a state where the pair of locking claws 103c are elastically deformed, it can be easily assembled.

  However, the max bet button 101 is generally operated with various operation forms and pressing forces. For example, the max bet button 101 is pressed by being struck by a pressing cover body 105c or the like of the movable portion 105 by a foreign object having a predetermined hardness such as a lighter, or is pressed with an unexpectedly large pressing force. Moreover, there are cases where such pressing operations are continuously performed.

  If the pressing operation of the max bet button 101 by such pressing operation is continued, only the force is received by the engagement between the casing receiving portion 113 of the front door 111 and the flange portion 103b of the casing 103, and therefore the flange portion 103b. May be damaged, or the flange portion 103b may be peeled off from the casing 103, and such a situation has actually occurred.

Further, when the flange portion 103b of the casing 103 is damaged, a gap is generated between the opening portion of the front door 111 and the casing 103 of the max bed button 101, and a foreign object such as a rod is inserted through the gap to play the game. It is also conceivable that an illegal act of operating predetermined switches inside the machine is performed. Therefore , the attachment structure of the max bet button 101 is strengthened .

  For example, Japanese Patent Application Laid-Open No. 09-206423 proposes a gaming machine having a push button operation switch housed in a switch box in a state where the movable part is fitted to the push button and the push button and the movable part are fitted in this way. Has been. The base of the switch box is formed in a cylindrical shape, and a screw groove is provided on the outer peripheral side of the cylindrical base.

Therefore, the force exerted on the switch unit can be distributed. Thereby, even if the pressing operation of the movable part of the switch unit is continuously performed with a pressing force exceeding a predetermined pressing force, the breakage of the first locking portion of the switch unit can be prevented.

Here, the predetermined pressing force on the movable portion of the switch portion means a normal pressing force exerted by a general operation mode on the switch portion when playing a game. In the present invention, exceeding the pressing force means, for example, that the movable part of the switch unit is struck with a foreign substance having a predetermined strength, or the movable part of the switch part is struck with a palm or the like without using a foreign substance. This means that a pressing force exceeding the above-mentioned normal pressing force is exerted. In the present invention, when the movable portion of the switch portion is pressed with such a pressing force, the first locking portion and the first locking receiving portion are locked, and the second locking portion and the second locking receiving portion are Thus, the conventional problems can be solved by receiving a pressing force with a plurality of locking structures. Therefore, when a normal pressing force is exerted, the pressing is performed by locking the first locking portion and the first locking receiving portion or by locking the second locking portion and the second locking receiving portion. You may make it receive a pressure, and you may receive a pressing force by these several latching structures.

Even if the first locking portion of the switch portion is damaged or the like, and a gap is generated between the casing of the switch portion and the first locking receiving portion, the second locking portion and the second locking portion. Since the locking with the stop receiving portion is performed inward from the first locking receiving portion of the gaming machine front door, the locking structure between the second locking portion and the second locking receiving portion is It is possible to prevent foreign objects such as rods from entering due to an obstacle. This makes it extremely difficult for foreign objects such as sticks to reach the inside of the gaming machine, so that it is possible to prevent an illegal act of operating switches inside the game.

And since the 2nd latching | locking part is provided in the pressing operation direction side of the movable part rather than the 1st latching | locking part of a casing, when a switch part is accommodated in a 1st latching receiving part, a game machine front surface It can be prevented from being exposed outward from the door. As a result, the second locking portion and the second locking receiving portion can be formed with a shape necessary and sufficient to receive and distribute the force exerted on the switch portion. Can be increased.

Then, if the force exerted on the switch portion can be received and dispersed by the locking of the second locking portion and the second locking receiving portion, the second locking portion locked to the opening edge portion of the first locking receiving portion. It is not necessary to form the one locking portion with a thickness so as to largely protrude from the front door of the gaming machine. Thereby, since it can comprise so that only the movable part of a switch part may protrude, the favorable operativity of a switch part can be ensured.

Mean 2. In the means 1, the second locking portion is formed such that a diameter of the casing is reduced at least once in the pressing operation direction side of the movable portion from the first locking portion of the casing to form a locking step surface on the outer peripheral surface side of the casing. The second latch receiving portion is provided by forming the latch step receiving surface so that the latch step surface of the casing can come into contact with the second latch receiving portion. The gaming machine is characterized in that the locking of the portion is performed by contact between the locking step surface and the locking step receiving surface.

The means 2 specifically defines the configurations of the second locking portion and the second locking receiving portion, and according to this, the second locking portion is movable from the first locking portion of the casing. Since the outer peripheral surface side of the casing is reduced in diameter at least once by the pressing operation direction side and formed by the locking step surface, and the second locking receiving portion is formed by the locking step receiving surface, the second locking The structure of a part and a 2nd latching receiving part can be simplified.

Here, the latching step receiving surface of the present invention is provided so as to be able to come into contact with the latching step surface of the casing because the movable part of the switch part is pushed down with a normal pressing force in a general operation mode. In this case, a sufficient pressing force can be received and dispersed by the locking structure of the first locking portion and the first locking receiving portion of the present invention. Therefore, when the movable part of the switch part is pressed with such a pressing force, the second locking part and the second locking receiving part are not locked.

When the movable part of the switch unit is operated with the pressing force that has been a problem in the past, the casing in which the switch unit is loaded also moves slightly in the pressing direction due to the impact of the pressing force. Is configured to be locked to the locking step receiving surface. As a result, when the movable part of the switch part is operated at least with the pressing force that has been a problem in the prior art, in addition to the locking between the first locking part and the first locking receiving part, The pressing force can be received by a plurality of locking structures that are locked with the stop receiving surface.

The game machine is characterized in that a front end portion of the locking claw portion can be brought into contact with a front end portion of the extending portion after the switch portion is received.

The means 4 specifically limits the configuration of the switch part. According to this, the locking claw part provided on the outer peripheral surface side of the casing of the switch part accommodates the switch part in the front door of the gaming machine. Since the distal end portion of the locking claw portion comes into contact with the distal end portion of the extending portion after the operation, a plurality of first locking portions, first locking receiving portions, second locking portions, and second locking receiving portions are provided. It is possible to prevent the switch part from being easily removed from the front door of the gaming machine after the switch part is attached while securing the attachment strength based on the locking structure.

Also, when the switch part is replaced due to damage to the first locking part, etc., it is only necessary to remove the switch part from the front door of the gaming machine with the locking claw part elastically deformed in the direction approaching the casing. Maintenance can be performed without complicating the work process. On the other hand, when the switch part is housed in the gaming machine front door, the switch part need only be inserted into the opening of the gaming machine front door with the locking claw part elastically deformed in the direction approaching the casing. The parts can be easily assembled.

Means 5. In the means 2 to 4, a movable portion receiving surface extending in a direction approaching each other corresponding to the position of the second locking portion of the casing is provided on the inner peripheral surface side of the casing. A game machine characterized in that movement is restricted when a movable part abuts against a movable part receiving surface of a casing by a pressing operation from a position.

The means 5 specifically limits the configuration of the switch part. According to this, the movable part receiving surface is provided corresponding to the position of the locking step surface on the outer peripheral surface side of the casing. The force exerted on the movable part receiving surface by the movement of the movable part in the pressing direction can be received by the locking structure of the locking step surface and the locking step receiving surface to disperse the force. Thereby, damage to the constituent members of the movable portion can be prevented. Further, the movement of the movable part pressed against the urging force is restricted by contact with the movable part receiving surface of the casing, so that the stroke of the movable part in the casing can be reduced. Thereby, when a pressing operation is performed with a pressing force that has been a problem in the past, the pressing force acting on the movable portion receiving surface, the locking step surface, and the locking step receiving surface can be reduced.

Means 6. In the means 1 to 5, the first locking receiving portion is formed by a stepped surface by recessing the gaming machine front door so that the first locking portion does not protrude from the surface of the gaming machine front door. A gaming machine characterized in that one locking portion is locked.

According to the means 6, when the first locking portion is locked to the first locking receiving portion formed as the step surface, the first locking portion does not protrude from the surface of the gaming machine front door. The locking between the stopping portion and the first locking receiving portion is performed without protruding outward from the gaming machine front door. Thereby, the favorable operativity with respect to the movable part of a switch part is securable, ensuring the latching structure of a switch part.

The first casing wall portion 43e and the second casing wall portion 43f are configured to extend further downward and reach the bottom plate portion 43g of the casing 43.

  A pair of locking claw portions 43k project from the lower position on the outer peripheral surface side of the cylindrical portion 43 so as to gradually move away from the cylindrical portion 43c as it moves upward. The pair of locking claws 43k are configured to be elastically deformed in a direction approaching the cylindrical portion 43c.

  The movable portion 45 moves downward in the casing 43 against the biasing force of the coil spring 47 by a pressing operation from a predetermined neutral position, and when the pressing operation state is released, the predetermined force is applied by the biasing force of the coil spring 47. It is configured to return to the neutral position, and has a slidable contact portion 45a that can slidably contact the inner peripheral surface of the cylindrical portion 43c of the casing 43, and a pressing cover body 45b provided on one side of the slidable contact portion 45a. is doing.

  The slidable contact portion 45a of the movable portion 45 is configured by a cylindrical body that has a size that allows sliding on the lower side of the movable portion receiving surface 43j on the inner peripheral surface side of the casing 43 and is open at both ends. Yes. On the outer peripheral side of the sliding contact portion 45a, a sliding contact projection 45c is provided so as to be in sliding contact with the inner peripheral surface of the casing 43 above the movable portion receiving surface 43j. The sliding contact portion 45 a is accommodated in the casing 43 with a packing 46 having a predetermined elasticity in between so that the sliding contact projection 45 c does not directly contact the movable portion receiving surface 43 j of the casing 43. Therefore, when the movable portion 45 is operated to push down the push-down cover body 45 b, the sliding contact portion 45 a moves while being in sliding contact with the inner peripheral surface side of the casing 43, and the sliding contact projection 45 c is movable through the packing 46. The movement is restricted by contacting the part receiving surface 43j.

  The push-down cover body 45b of the movable portion 45 receives a light transmitting sheet 45e provided so as to cover one opening of the sliding contact portion 45a and light transmitted through the light transmitting sheet 45e, and emits light outward. And a lens portion 45f for appropriately diffusing the light. The light transmitting sheet 45e of the pressing cover body 45b is constituted by a single sheet extending with substantially the same size as the opening of the sliding contact portion 45a. In order to identify the Max bet button 41, ink that absorbs light is used. The characters “MAX BET” are printed. The lens portion 45f of the push-down cover body 45b is slightly larger than the opening of the sliding portion 45a, and is formed of a transparent plastic.

  The coil spring 47 is configured to exert an urging force that moves the movable part 45 upward and returns it to the neutral position with respect to the movable part 45 that moves downward in the casing 43.

  The detection means 49 outputs a signal related to the pressing operation of the max bet button 41, and includes a photocoupler 49d including a light projecting unit 49b and a light receiving unit 49c mounted on the substrate 49a, a light projecting unit 49b, The LED 49e is disposed opposite to each other with an optical path between the light receiving unit 49c and the photocoupler 49d and the line connector 49f for the LED 49e.

  Next, a specific configuration of the latch receiving portion 50 of the present invention will be described. The latch receiving portion 50 of the present invention is in contact with the casing receiving portion 51 that receives the flange portion 43b provided on the casing 43 of the max bed button 41 when the max bed button 41 is accommodated, and the latching step surface 43h. And a locking step receiving surface 53 for locking.

  The casing receiving part 51 is provided at the opening edge part of the opening part 6 that accommodates the Max bet button 41 formed in the flat part F of the front door 3, and constitutes the first locking receiving part of the present invention. ing. Specifically, the casing receiver 51 is formed by recessing the opening edge of the opening 6 provided in the flat portion F of the front door 3 to provide a stepped surface, and the opening 6 of the front door 3. A vertical wall surface 51a that is suspended from the horizontal wall 51b, and a horizontal surface 51b that is bent vertically at the lower end of the vertical wall surface 51a and extends in a direction approaching each other. The locking surface 43d of the flange portion 43b is configured to receive the max bed button 41 by contacting and locking to the horizontal surface 51b of the casing receiving portion 51.

  Further, the vertical wall surface 51 a of the casing receiving portion 51 is so high that the flange portion 43 b does not protrude from the flat portion F of the front door 3 when the flange portion 43 b of the casing 43 is locked to the horizontal surface 51 b of the casing receiving portion 51. It is formed with. Thereby, since only the substantially upper part of the sliding contact part 45a of the movable part 45 and the pressing cover body 45b protrude outward from the plane part F of the front door 3, good operability of the Max bet button 41 is ensured. be able to. In addition, since the movable portion 45 does not protrude, it is possible to prevent the appearance design of the slot machine 1 from being adversely affected.

  The casing receiving portion 51 is configured such that the flange portion 43b of the casing 43 is locked to the flat surface portion F of the operation portion 3B as in the prior art without providing the stepped surface by recessing the opening edge portion of the opening portion 6. It is also possible.

  The locking step receiving surface 53 is formed on the inner peripheral surface 52a side of the cylindrical hollow body 52 that is suspended from the casing receiving portion 51 and corresponds to the outer shape of the casing 43 of the max bet button 41 and constitutes the extending portion of the present invention. Thus, the second latch receiving portion of the present invention is configured. Specifically, the engaging step receiving surface 53 is formed by projecting the inner peripheral surface 52 a side of the cylindrical hollow body 52 in a direction approaching each other at a position corresponding to the engaging step surface 43 h of the casing 43. It is provided in the horizontal part.

  As shown in FIG. 6, the engaging step receiving surface 53 is configured to be able to contact almost the entire engaging step surface 43 h of the casing 43. The extending portion of the present invention may have any structure as long as it forms the locking step receiving surface 53 and can be locked with the locking step surface 43 h of the casing 43. For example, the extending portion may be configured by a pair of plate-like support members that are provided at a slightly wider interval than the casing 43 and are suspended from the casing receiving portion 51. Then, the engaging step receiving surface formed on the inner surface side of the pair of plate-like members can contact at least the engaging step surface 43h on the first casing wall 43e side or the second casing wall 43f side.

  The engaging step receiving surface 53 is provided at a position corresponding to the position of the engaging step surface 43 h of the casing 43 and is configured to always contact and engage with the engaging step surface 43 h. It is not limited to. For example, the latching step receiving surface 53 is provided at a position slightly below the position where the latching step receiving surface 43h of the casing 43 always abuts, and is disposed facing each other with the latching step receiving surface 53 and the latching step surface 43h being very close to each other. It is also possible to do so. When the movable part 45 of the max bet button 41 is pushed down with an extremely large pressing force, which has been a problem in the prior art, the sliding contact protrusion 45c of the movable part 45 that has moved downward is placed on the casing 43 via the packing 46. The casing 43 also moves slightly downward due to the impact abutting against the movable part receiving surface 43j. At this time, if the locking step surface 43h of the casing 43 slightly moved downward is in contact with the locking step receiving surface 53, a plurality of pressing forces received by the movable portion 45 of the max bed button 41 as described above are obtained. It is possible to receive and disperse with the locking structure.

  As described above, the flange 43b of the casing 43 and the casing receiving portion are accommodated when the max bed button 41 is accommodated by contacting the locking step surface 43h of the casing 43 when the pressing operation is performed with at least a very large pressing force. Since only 51 needs to be locked, positioning of the max bet button 41 is facilitated.

  And the bottom face 52c which connects the lower end of the internal peripheral surface 52a and the lower end of the outer peripheral surface 52b is formed in the lower end part of the hollow cylindrical body 52. As shown in FIG. The bottom surface 52c of the hollow cylindrical body 52 is formed so that the upper ends of the pair of locking claws 43k can come into contact with each other when the max bed button 41 is accommodated. As a result, even if the movable portion 45 or the like of the max bet button 41 is gripped and taken out, the upper ends of the pair of locking claws 43k abut against the bottom surface 52c of the hollow cylindrical body 52, and the max bet button 41 is removed. I can't.

Accordingly, the locking step surface 43h of the casing 43 is brought into contact with the locking step surface receiving surface 53 , so that the outer peripheral surface side of the casing 43 is locked and supported. 41 can be supported.

Further, since the locking is performed by the contact surface by the horizontal surface 53b of the locking step surface receiving surface 53 and the locking step surface 43h of the casing 43, a high mounting strength of the Max bet button 41 can be obtained. Further, the force exerted on the max bet button 41 can be well distributed by the locking by the contact surface.

  In addition, the flange 43b and the locking step surface 43h of the casing 43 need only be locked to the casing receiving portion 51 and the locking step receiving surface 53, respectively, with the pair of locking claws 43k elastically deformed. Thus, it is possible to easily assemble the max bet button 41 while ensuring a high mounting strength of the max bet button 41.

  Then, the engaging stepped surface receiving surface 53 is formed on the inner peripheral surface 52a side of the cylindrical hollow body 52 suspended from the casing receiving portion 51 of the front door 3 at a position below the casing receiving portion 51. Parts for providing the locking step surface receiving surface 53 at a predetermined position are not required. Thereby, the number of parts can be reduced, and the cost of the max bet button 41 can be reduced.

  Next, the main control board 60 and the like of the slot machine 1 disposed in the control board storage box 12 will be described with reference to FIG. FIG. 9 is a block diagram illustrating the electrical configuration of the slot machine 1.

  The main control board 60 is equipped with an MPU 61 as a one-chip microcomputer, which is an arithmetic unit, and an input / output port 62 connected to the MPU 61 and connected to various input / output means such as sensors and switches. Yes.

  The MPU 61 temporarily stores a control program such as a game control program executed by the MPU 61 and a ROM 63 storing predetermined fixed value data, and various data and the like when executing the control program stored in the ROM 63. A RAM 64 or the like, which is a memory for this purpose, is built in.

  The input / output port 62 is connected to a max bet button 41, a start lever 35, a stop button 36, a bet lamp 25, a credit number display unit 26, a sub control board 70, and the like.

  The sub-control board 70 receives a command transmitted from the main control board 60 and performs a predetermined control process. In the present embodiment, the sub-control board 70 is configured to perform output control of sound effects from the speaker 22. Has been.

  The power supply board 80 is provided in the power supply box 13, and in addition to the main control board 60, a power supply unit 81 that supplies driving power to each electronic device of the slot machine 1 such as the max bet button 41, and a power cut-off Various circuits such as a power failure monitoring circuit 82 for monitoring the occurrence are provided. After the slot machine 1 is powered off, a backup voltage is supplied from the power supply unit 81 of the power supply board 80 to the RAM 64.

  The MPU 61 constitutes a control means that performs various processes by executing programs stored in the ROM 63 based on detection signals from various sensors and switches connected to the input / output port 62.

  For example, the MPU 61 first determines whether or not a predetermined number of coins have been inserted by inserting coins from the coin insertion slot 33. Alternatively, the MPU 61 determines whether a predetermined number of coins are stored electronically in advance. When a coin is inserted from the coin insertion slot 33, the display on the credit amount display unit 26 increases in accordance with the inserted number. Alternatively, when coins are stored electronically in advance, the number of stored coins is displayed on the credit number display unit 26.

  When a detection signal related to the operation of pressing the max bet button 41 is input from the detection means 49 via the input / output port 62, the MPU 61 analyzes the game control program and determines whether the max bet button 41 is pressed. Judge whether or not. If it is determined that the operation is a press operation of the Max Bet button 41, a signal for outputting the sound effect of the speaker 22 is output to the sub control board 70 via the output port 62, and power is supplied from the sub control board 70 to the speaker 22. Then, a process for outputting sound effects is performed. Further, all the bet lamps 25 are turned on simultaneously with the output of the sound effect from the speaker 22.

  According to the slot machine 1 having the above configuration, in addition to the engagement between the engagement surface 43d of the flange portion 43b and the horizontal surface 51b of the casing receiving portion 51, the engagement between the engagement step surface 43h and the engagement step receiving surface 53 is achieved. Since the max bed button 41 accommodated by the stop is received, the force exerted on the pressing cover body 45b of the movable portion 45 can be received by the plurality of locking structures and can be appropriately dispersed.

  In particular, the pressing cover body 45b of the movable part 45 is pressed by, for example, pressing with a very large pressing force, or by being struck by a foreign object such as a lighter having a predetermined hardness, and the pressing operation continues. Even in such a case, the force received by the pressing cover body 45b of the movable portion 45 is appropriately dispersed, so that the flange portion 43b of the casing 43 can be prevented from being damaged.

  Even when the flange 43b of the casing 43 is damaged or the like, the engagement between the engagement engagement step surface 43h and the engagement step receiving surface 53 is performed at a position below the casing reception portion 51 of the front door 3. Therefore, it is possible to prevent a gap from being generated between the casing 43 and the casing receiving portion 51 or the locking step receiving surface 53. Therefore, even when trying to insert a foreign object such as a rod, it is extremely difficult to reach the inside of the slot machine 1, so that an illegal act of operating the switches inside the main body 4 of the slot machine 1 can be prevented. .

  Further, the replacement of the max bet button 41 due to the breakage of the flange portion 43b or the like only needs to be taken out from the casing receiving portion 51 in a state where the pair of locking claws 43k are elastically deformed, so that the work process is not complicated. Maintenance can be performed. On the other hand, when the max bet button 41 is attached, it is only necessary to accommodate the pair of locking claws 43k from the opening of the front door 3 in a state of being elastically deformed, so that the max bet button 41 can be easily assembled. Can do.

  Then, since the locking step surface 43 h is provided below the flange portion 43 b of the casing 43, it is exposed to the flat portion F of the front door 3 when the max bed button 41 is accommodated in the casing receiving portion 51. There is nothing. Thereby, since it can form with sufficient shape required to receive the force exerted on the pressing cover body 45b of the Max bet button 41, the freedom degree of design can be raised.

  Further, if the force exerted on the push-down cover body 45b of the max bed button 41 can be sufficiently received by the engagement between the engagement / engagement step surface 43h of the casing 43 and the engagement step receiving surface 53, the casing receiving portion It is not necessary to form the flange portion 43b to be engaged with the horizontal surface 51a of the 51 with a thickness so as to largely protrude from the horizontal portion F of the front door 3. Thereby, the favorable operativity of the movable part 45 of the max bet button 41 is securable.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, one of the other bet button switches provided on the horizontal plane F of the front door 3 and the two bet switch buttons 31, 32, and the respective stop buttons provided on the vertical wall portion H of the front door 3. 36 can be configured in the same manner as the max bet button 41 of the present invention. Further, in the present embodiment, the start lever 35 is configured by a lever type that protrudes toward the front side from the vertical wall portion H of the front door 3, but when configured by a switch type, the max of the present invention. A configuration similar to that of the bet button 41 can be adopted. Furthermore, in the present embodiment, the Max bed button 41 is configured to be fixedly attached to the flat surface portion F of the front door 3, but may be configured to be fixedly attached to the vertical wall portion H of the front door 3. .

  Then, in the present embodiment, one locking step surface 43h is provided on the outer peripheral surface side of the casing 43, but a plurality of locking step surfaces may be provided on the outer peripheral surface side of the casing 43. good. For example, at the position below the locking step surface 43h of the casing, the outer peripheral surface side of the casing 43 is reduced in diameter so as to approach each other to form a locking step surface similar to the locking step surface 43h. That is, at a position below the flange portion 43 b of the casing 43, two or more locking step surfaces can be provided on the outer peripheral surface side of the casing 43 by reducing the diameter at least twice as it moves downward.

  Thereby, the outer peripheral surface side of the casing 43 can provide a some level | step difference surface in the step shape in the direction which mutually approaches as it moves below. When a plurality of locking step surfaces are provided on the outer peripheral surface side of the casing 43, a plurality of locking step receiving surfaces that receive the respective locking step surfaces are provided correspondingly.

  As described above, by providing a plurality of locking step surfaces on the outer peripheral surface side of the casing 43, a plurality of support structures for the max bet buttons 41 by contact between the locking step surfaces and the locking step receiving surfaces are provided. Therefore, the force exerted on the pressing cover body 45b of the movable part 45 can be further dispersed. Thereby, since the force received by the flange part 43b of the casing 43 can be made small, damage to the flange part 43b etc. can be prevented. In particular, such an effect is remarkable when the pressing operation is performed with a very large pressing force, which has been a problem in the past, or when the pressing operation is performed by being struck by a foreign object having a predetermined strength such as a lighter. Become.

  Even if the flange 43b of the casing 43 is damaged, the max bed button 41 is locked by the plurality of locking step surfaces and the locking step receiving surfaces. Can be prevented from falling into the front door 3.

  Further, these locking step surface and locking step receiving surface are not exposed to the outside when the Max Bet button 41 is attached and fixed, so that the design of the slot machine 1 is not adversely affected. Since the size of the surface, the number of steps of the engaging step surface, etc. can be set freely, a degree of freedom in design can be obtained.

  Further, since the foreign object such as the rod body cannot enter or is substantially impossible due to the locking between the plurality of locking step surfaces and the locking step receiving surface, It is possible to prevent an illegal act of operating the provided switches.
