One member 3 is urged toward one member 13, 1 of the second member 1 and the third member 13, and the first member 3 and the one member 13, 1 are in an approaching state. A detection switch 25 that is sometimes pressed toward the first member 3 by the one member 13, 1 is provided. When the detection switch 25 is in a pressed state by the one member 13, the first member 3 has a sensor 31 that senses the other member 1, 13 of the second member 1 and the third member 13, and does not sense the other member 1, 13 at other times. Is.

  Another aspect of the present invention is a game provided with a front frame 3 having a game part on the front side of the gaming machine main body 1 so as to be opened and closed, and provided with an opening / closing door 13 on the front side of the front frame 3 so as to cover the game part so as to be visible. In the machine, a detection switch 25 provided on the front frame 3 so as to be movable in the front-rear direction between an urging position A and a pressing position B, and urging the detection switch 25 to the urging position A. The biasing means 29 and the pressing position provided against the biasing means 29 when the opening / closing door 13 or the gaming machine body 1 is closed and the door 13 or the front frame 3 is closed. A pressing portion 30 that presses toward B, and the detection switch 25 is closed when the front frame 3 or the open / close door 13 is closed, and when the detection switch 25 is in the biased position A, the gaming machine main body. 1 or the opening / closing door 13 is not sensed and the pressing position B is not detected. And it has a sensing element 31 for sensing the gaming machine main body 1 or the door 13 to Rutoki.

  In the present invention, it is possible to detect whether or not two members are in an approaching state by one detection switch, for example, whether or not the front frame and the open / close door are in a closed state with respect to the gaming machine main body.

The sensor 31 does not sense the outer frame 1 when the front frame 3 is opened, Even when closed, the outer frame 1 is not sensed when the support base 28 and the detection switch 25 are at the biased position A, and the outer frame 1 is sensed when the support base 28 and the detection switch 25 are at the pressing position B. It is configured. The detection switch 25 outputs an open signal such as an ON signal when the sensor 31 does not detect the outer frame 1 and outputs a close signal when it is detected.

  The upper edge portion 7 of the front frame 3 has two upper and lower horizontal plate portions 32 and a vertical plate portion 33 that vertically connects the rear end or middle of the horizontal plate portion 32, and a substantially central portion thereof in the left-right direction. In addition, a rectangular cylindrical protection part 34 is provided that protrudes backward on the extension of the upper and lower two horizontal plate parts 32. An attachment portion 35 is integrally provided in the protection portion 34 at a position that protrudes rearward from the vertical plate portion 33 of the upper edge portion 7 in the middle in the front-rear direction, and guide means 27 is provided to the attachment portion 35 in the protection portion 34. The support base 28, the biasing means 29, the detection switch 25, the cover 36, and the like are incorporated.

  The detection switch 25 includes a main body 37, a sensor 31 that protrudes from and retracts from the main body 37, and a sensor 31 that is provided in the main body 37 and protrudes rearward from the rear end of the protection unit 34. It has a spring 38 to be biased and a connector 39 provided on the opposite side to the sensor 31 of the main body 37 and is detachably attached to the support base 28. The main body 37 is provided with a flange 40 on the side of the sensor 31 and elastic pieces 41 on both the left and right sides.

  The support base 28 is formed in a box shape having an opening on the front side, and has a housing portion 42 for housing the detection switch 25 therein, and guided portions 43 provided on both left and right sides of the housing portion 42. A cover 36 is mounted so as to contact the front surface and cover the detection switch 25 inside from the front side. An attachment hole 44 and an engagement hole 45 are formed in the rear end wall 62 of the accommodating portion 42.

  The detection switch 25 is detachably fixed to the rear wall by the elastic piece 41 in a state where the main body portion 37 is inserted into the mounting hole 44 of the rear end wall 62 from the rear side and the flange portion 40 is in contact with the rear end wall 62. ing. The sensor 31 of the detection switch 25 protrudes backward from the support base 28 and the rear end wall 62.

  The cover 36 is configured in a box shape with an open rear side, and is detachably attached to the support base 28 by a pair of left and right engaging claws 46 that are inserted into the receiving portion 42 and detachably engage with the engaging holes 45. Has been. The front surface of the cover 36 is a pressed portion 47 that is pressed by the pressing portion 30.

  The guide means 27 is provided on both the left and right sides of the opening 48 and has a guide protrusion 49 that protrudes forward from the attachment portion 35. The guide projection 49 is slidably inserted in the guided portion 43 of the support base 28 in the front-rear direction, and is detachably fixed to the rear end of the guide projection 49 with a screw 50 for a retaining portion. The guided portion 43 has a bottomed cylindrical shape, and a biasing means 29 is interposed between the guided portion 43 and the attachment portion 35. The urging means 29 is composed of an urging spring 51 such as a compression coil spring and is fitted onto the guide protrusion 49.

  The pressed portion 47 of the cover 36 is located behind the front end of the upper edge portion 7. Therefore, the guide means 27, the support base 28, the detection switch 25, and the cover 36 are within the front-rear width of the upper edge portion 7, and are protected by the upper and lower horizontal plate portions 32.

  The pressing portion 30 is configured by a protrusion that protrudes rearward from the rear end of the opening / closing door 13 so as to face the pressed portion 47 of the opening / closing door 13. The pressing portion 30 is formed integrally with the frame plate 18 of the open / close door 13 and protrudes rearward through the hole of the reinforcing plate 20.

  The horizontal frame member 5 on the upper side of the outer frame 1 is formed with a notch 52 corresponding to the protective part 34 on the front frame 3 side so as to be recessed to the rear side, and the front frame 3 is closed. Sometimes, the protective part 34 enters the recessed part 52. In the recessed portion 52, a sensed portion 53 with which the sensor 31 comes into contact is formed in a flat shape.

  As shown in FIG. 11, the detection switch 25 is connected to the main control board 55, the frame external connection terminal 56, and the like via the payout control board 54. The payout control board 54 is for controlling payout means for paying out game balls. The main control board 55 is for controlling the game operation on the game board 10 side. When there is an open signal for detecting the opening of the front frame 3 and the door 13 from the detection switch 25, the main control board 55 is transferred to the effect control board 57. A notification command is issued.

  When there is a notification command, the effect control board 57 notifies the opening by a notification means 58 such as a lamp or a speaker. The frame external connection terminal 56 transmits an open signal to the management device 59 such as an external management computer when there is an open signal for detecting the opening of the front frame 3 and the door 13 from the detection switch 25. ing.

  With such a configuration, the opening / closing of the front frame 3 and the open / close door 13 can be detected by one detection switch 25, and there is an advantage that the structure can be simplified. That is, when the front frame 3 and the open / close door 13 are closed, the outer peripheral portion of the front frame 3 is in contact with the front surface of the outer frame 1, and the outer peripheral portion of the open / close door 13 is in contact with the front surface of the front frame 3.

  In this state, as shown in FIG. 6, the pressing portion 30 of the open / close door 13 abuts against the pressed portion 47 of the cover 36 of the support base 28, and presses the support base 28 forward against the biasing spring 51. The support base 28 and the detection switch 25 are in the pressing position B. For this reason, the sensor 31 of the detection switch 25 is in contact with the sensed part 53 of the outer frame 1 to sense the outer frame 1. Then, a close signal indicating that both the front frame 3 and the open / close door 13 are closed is transmitted from the detection switch 25 to the main control board 55 and the frame external connection terminal 56.

  When the door 13 is opened around the hinge 2 in the closed state where the front frame 3 is closed with respect to the outer frame 1, the door 13 is separated from the front frame 3 to the front side as shown in FIG. 3 and the opening / closing door 13 create a gap, and the pressing portion 30 moves away from the pressed portion 47 of the opening / closing door 13 to the front side. The support base 28 and the detection switch 25 are moved from the pressing position B to the biasing position A along the guide protrusion 49 by the biasing force of the biasing spring 51, and the sensor 31 of the detection switch 25 is pushed back by the spring 38. However, the detection switch 25 detects the opening of the open / close door 13 because it is away from the sensed portion 53 of the outer frame 1.

  When the front frame 3 is opened around the hinge 2 in the closed state where the open / close door 13 is closed with respect to the front frame 3, the front frame 3 is separated from the outer frame 1 to the front side as shown in FIG. A gap is formed between the frame 1 and the front frame 3. Even though the support base 28 is pressed by the pressing portion 30 of the open / close door 13 and is in the pressing position B, the sensor 31 of the detection switch 25 is separated from the sensed portion 53 of the outer frame 1 and pushed back by the spring 38. Therefore, the detection switch 25 detects the opening of the front frame 3.

When the detection switch 25 detects the opening of the front frame 3 and the open / close door 13, an open signal such as an ON signal is sent to the main control board 55 and the frame external connection terminal 56 via the payout control board 54. Then, a notification signal is sent from the main control board 55 to the effect control board 57, and a notification means 58 such as a lamp notifies the opening of the front frame 3 or the open / close door 13. On the other hand, since an open signal is transmitted from the frame external connection terminal 56 to the management device 59, the front frame 3 and the door 1 are also opened on the management device 59 side.
3 can be grasped.

  Therefore, if there is an illegal act in which the player opens the front frame 3 or the open / close door 13 illegally, the opening can be reliably detected by the single detection switch 25. The fact can be notified by the notification means 58 and can also be managed on the management device 59 side.

  Further, the detection switch 25 is provided on the support base 28, and the support base 28 is movably supported by a pair of guide means 27, and the detection switch 25 is pressed via the support base 28 by the pressing portion 30 of the door 13. Therefore, the detection switch 25 can be guided smoothly, and an excessive mechanical load is not applied to the detection switch 25.

  The front frame 3 is provided with a protective portion 34 that projects to the outer frame 1 side, and a guide means 27, a support base 28, an urging means 29, and a detection switch 25 are incorporated on the front side of the protective portion 34, and the front frame 3 is closed. Since the recessed portion 52 into which the protective portion 34 is inserted is provided in the outer frame 1 and the pressing portion 30 is provided so as to protrude from the opening and closing door 13, the protective portion 34 reduces the size of the front frame 3 in the front-rear direction. The guide means 27, the support base 28, the detection switch 25, etc. can be protected.

  The guide means 27 is constituted by a guide protrusion 49 that protrudes forward from the mounting portion 35 in the protection portion 34 and is slidably inserted into the guided portion 43 of the support base 28, and the guided portion 27 and the support base 28 are guided. Since the biasing spring 51 is provided between the portion 43 and the support 43, the support base 28 can be reliably guided with a simple structure.

  In addition, the detection switch 25 is accommodated in the accommodating portion 42 of the support base 28, and the detection switch 25 can be reliably protected by covering the detection switch 25 in the accommodating portion 42, and the optimum position is pressed regardless of the detection switch 25. It can be pressed by the part 30.

  12-14 illustrate a second embodiment of the present invention. In this embodiment, an attachment portion 35 is provided on the front end side of the protection portion 34 and between the upper and lower horizontal plate portions 32, and the guide means 27, the biasing means 29, and the support are provided on the rear side of the attachment portion 35 in the protection portion 34. The base 28, the detection switch 25, the cover 36, and the like are incorporated in the reverse direction.

  The cover 36 includes a pressed portion 47 configured in a spherical shape or other shapes, and the pressed portion 47 is pressed by the pressing portion 30 in the recessed portion 52 of the outer frame 1. The sensor 31 of the detection switch 25 projects forward between the upper and lower horizontal plate portions 32 and senses the sensed portion 53 at the rear end of the projection 63 projecting rearward from the open / close door 13.

  In this case, when the front frame 3 and the open / close door 13 are closed, the pressed portion 47 of the cover 36 is pressed against the biasing spring 51 by the pressing portion 30 of the outer frame 1 as shown in FIG. The support base 28 and the detection switch 25 are in the pressing position B, and the sensor 31 of the detection switch 25 senses the sensed part 53 of the door 13.

  When the opening / closing door 13 is opened around the hinge 2 in the closed state of the front frame 3, the opening / closing door 13 is separated from the front frame 3 to the front side as shown in FIG. 13, and between the front frame 3 and the opening / closing door 13. A gap is formed, and the sensor 31 moves away from the sensed part 53 of the door 13 to the front side. For this reason, even though the support base 28 is pressed by the pressing portion 30 of the outer frame 1 and is in the pressing position B, the sensor 31 of the detection switch 25 moves away from the sensed portion 53 of the open / close door 13 and the detection switch 25. Detects the opening of the front frame 3.

  When the front frame 3 is opened around the hinge 2 in the closed state of the door 13, the front frame 3 is separated from the outer frame 1 to the front side as shown in FIG. 14, and between the outer frame 1 and the front frame 3. Since the gap is formed, the support base 28 and the detection switch 25 are moved from the pressing position B to the urging position A by the urging force of the urging spring 51, and the sensor 31 of the detection switch 25 is the sensed portion 53 of the door 13. The detection switch 25 detects the opening of the front frame 3.

  15 to 17 illustrate a third embodiment of the present invention, which employs a non-contact type detection switch 25. The detection switch 25 includes a sensor 31 that includes a light emitting element 60 and a light receiving element 61 that receives the light. The detection switch 25 transmits light from the light emitting element 60 to the light receiving element 61 on the recessed portion 52 side of the outer frame 1. A plate-like or other sensed part 53 that can be shut off is provided. The sensor 31 may be a proximity switch using an element other than the light emitting element 60 and the light receiving element 61.

  Even in such a case, if the front frame 3 and the door 13 are closed, the sensed part 53 enters between the light emitting element 60 and the light receiving element 61 of the sensor 31, as shown in FIG. The sensor 31 senses the sensed part 53, and the detection switch 25 outputs a closing signal.

  When the open / close door 13 is opened while the front frame 3 is closed, the support base 28 is moved to the urging position A by the urging spring 51 as shown in FIG. When the front frame 3 is opened while the door 13 is closed, the support base 28 is separated from the outer frame 1 to the front side as shown in FIG.

  For this reason, the sensed part 53 is moved backward from between the light emitting element 60 and the light receiving element 61 of the sensor 31, so that the light receiving element 61 receives the light from the light emitting element 60, and the detection switch 25 is moved forward. The opening of the frame 3 and the opening / closing door 13 is detected and an opening signal is output.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to these Examples, A various change is possible in the range which does not deviate from the meaning of this invention. In each embodiment, a ball game machine such as a pachinko machine in which the front frame 3 is detachably attached to the outer frame 1 and the opening / closing door 13 is detachably attached to the front frame 3 is illustrated. The present invention can be similarly applied to portions other than the frame 1, the front frame 3, and the opening / closing door 13. Also, the present invention can be applied to a gaming machine such as a slot machine in which a front frame 3 is detachably attached to a gaming machine main body such as a housing, and an opening / closing door 13 is detachably attached to the front frame 3.

  The detection switch 25, the protection part 34, and the like are not limited to the upper part of the front frame 3, and may be provided at predetermined positions such as the side part and the lower part of the front frame 3. For example, when the detection switch 25 or the like is provided on the side of the lock side opposite to the hinge 2, the open state of the front frame 3 and the open / close door 13 can be detected effectively.

  Further, in the relationship between the gaming machine main body, the front frame 3 and the open / close door 13, the front frame 3 and the open / close door 13 open and close around the hinges 2 and 15. For example, the game parts are placed on the back side of the game board 10 inside. A protective cover that covers the cover may be attached to the opening / closing door 13 by the hinge 2 and the cover that closes the inspection window of the protective cover may be employed at a position pivotally attached to the opening / closing door 13 by the hinge.

  Further, even in a structure in which the second member and the third member are arranged on both sides of the intermediate first member so as to be movable in the perspective direction, the same operation is performed by providing the first member with the detection switch 25, the support base 28, and the like. Is possible. The main body portion 37 of the detection switch 25 may be provided movably by the guide means 27, and the support base 28 may be omitted. The guide means 27 and the support base 28 may have other structures. The biasing means 29 may be constituted by another spring.
