Description

  The present invention relates to a gaming machine in which a front door is pivotally supported so as to be openable and closable via a hinge mechanism with respect to a gaming machine body, and more particularly to a sag prevention structure that prevents the front door from falling downward due to its own weight. is there.

  A pachinko machine, which is an example of a gaming machine, is a vertical rectangular machine frame installed on an island facility in a game arcade, and a main body frame (a gaming machine main body) attached to this machine frame in a door-like manner via a hinge. And a front door attached to the front face of the main body frame via another hinge so as to be openable and closable. A game board, a launching device and the like are accommodated inside the main body frame. The game board has a game area defined by guide rails and the like, and this game area is provided with a variable display device, a start winning port, a general winning port, an attacker device, a game nail, a windmill, an out port, etc. ing. A locking device that locks / unlocks the open end (on the anti-hinge side) of the front door is provided on the front face of the main body frame. Normally, the open end of the front door is locked with respect to the main body frame. An opening facing the board surface of the game board is provided at the center of the front door, and this opening is closed by a transparent plate. In addition, the front door is provided with an effect device such as an electric decoration part and a speaker so as to surround the opening, and a lower part of the front door is a receiving tray for storing a game ball and an operation handle for adjusting the firing strength of the launching device. Etc. are provided.

  In the pachinko machine schematically configured in this way, the main body frame is usually closed with respect to the machine frame, and the front door is also closed with respect to the main body frame. It is impossible to touch etc. However, the front door may be opened in order to eliminate ball clogging or the like that has occurred on the game board. In this case, the front door rotates about the hinge with respect to the main body frame. Here, since the front door is equipped with various parts such as a production device and an operation handle, the total weight of the front door may become quite large. In such a case, the anti-hinge side of the front door The phenomenon of “sagging” that falls downward with time is likely to occur.

  Therefore, conventionally, an insertion member made of an L-shaped bracket is attached to the back surface of the front door on the side opposite to the hinge, and an L-shaped receiving member is attached to the front surface of the gaming machine main body. A gaming machine (slot machine) has been proposed in which a protruding piece extending in a horizontal direction is brought into contact with a support plate of a member so that the anti-hinge side of the front door does not fall downward due to its own weight (for example, a patent) Reference 1). In such a conventional technique, when the front door in the open state is closed with respect to the gaming machine body, the protruding piece of the insertion member is guided to the back side of the receiving member while sliding on the upper surface of the support plate. The downward movement acting on the anti-hinge side is restricted by the receiving member, and the front door can be prevented from drooping downward due to its own weight.

JP 2005-296542 A

  By the way, in the prior art disclosed by patent document 1, since the insertion member attached to the back side of the front door and the receiving member attached to the front side of the gaming machine main body are both made of a metal material, If the opening / closing operation is repeated with respect to the main body of the gaming machine, the sliding parts of the insertion member and the receiving member are worn in a relatively short period of time due to the friction between the metal of the insertion member and the receiving member. As a result, there is a problem that it is difficult to smoothly open and close the front door. In order to prevent the insertion member and the receiving member from sliding on each other, it is possible to use either one or both of the insertion member and the receiving member as a synthetic resin molded product. Another problem arises in that the grounding structure for escaping to the outside becomes complicated.

  That is, the exterior body of the front door is generally formed of an insulating synthetic resin, and various electrical parts that are susceptible to static electricity are housed inside such an exterior body. Alternatively, it is necessary to ground the charged static electricity to the gaming machine main body side through a desired conductive path. However, since the front door is pivotally supported by the gaming machine main body via a hinge mechanism so that the front door faces the gaming machine main body only when it is closed, as described above, the insertion member and the receiving member When at least one of these is molded with synthetic resin, the lead wire connected to the conductive plate or the like provided on the front door must be connected to the ground terminal of the gaming machine body via the hinge. There arises a problem that space efficiency deteriorates and maintenance work becomes complicated.

  The present invention has been made in view of the actual situation of the prior art, and an object of the present invention is to simplify the grounding structure and to smoothly perform opening and closing operations while preventing the front door from drooping due to its own weight. Is to provide a machine.

  In order to achieve the above object, the present invention comprises a gaming machine main body provided with a receiving member on the lower front side, and a front door provided with a sag preventing member on the lower rear side, wherein the front door is In the gaming machine, which is pivotally supported in front of the gaming machine body via a hinge mechanism so as to be opened and closed, and the drooping prevention member is supported by the receiving member when the front door is closed, the dripping prevention The member is composed of a synthetic resin insertion body having a protrusion and a metal leaf spring having a contact piece, and the contact piece protrudes downward from an opening provided on the bottom surface of the protrusion, and the receiving member Is made of a sheet metal grounding plate connected to the ground, and when the front door is closed, the lower surface of the protruding portion is brought into contact with the grounding plate and the contact piece is elastically contacted with the grounding plate. I made it.

  In the gaming machine configured as described above, when the front door is closed with respect to the gaming machine main body, the protruding portion of the insert provided on the lower back side of the front door is provided on the lower front side of the gaming machine main body. Since it abuts on the receiving member (ground plate), the front door can be reliably prevented from drooping downward due to its own weight. When the front door is opened and closed with respect to the gaming machine main body, the lower surface of the protruding portion formed of synthetic resin slides on the sheet metal receiving member, so that the sliding of both is smooth and the front door Can be opened and closed smoothly. Further, since the contact piece of the leaf spring that protrudes downward from the bottom surface of the protruding portion when the front door is closed is elastically contacted on the receiving member (ground plate), static electricity generated or charged on the front door is passed through the leaf spring and the receiving member. Thus, it is possible to ground to the gaming machine main body side, and it is possible to realize a compact and simplified ground structure using a front door droop prevention structure.

  In the above configuration, the contact piece is formed in a cantilever shape on the leaf spring, and the insertion recess is provided with a storage recess that surrounds the free end side of the contact piece. If the position of the free end is elastically contacted with the inner bottom surface of the storage recess and the position is restricted, when the front door is opened, the free end side of the contact piece is caught by an operator or the like, and it is inadvertently deformed. Can be prevented.

  In the gaming machine of the present invention, the front door is prevented from sagging by using a synthetic resin insertion body provided on the front door and a sheet metal receiving member (grounding plate) provided on the gaming machine main body. When the front door is opened and closed with respect to the gaming machine main body, the sliding between the protrusion of the insert and the ground plate is smoother than that between metals, so the front door can be opened and closed smoothly. In addition, since the contact piece of the leaf spring that protrudes downward from the bottom surface of the protruding portion is elastically contacted on the receiving member when the front door is closed, the static electricity generated or charged on the front door is played through the leaf spring and the receiving member. It can be grounded to the machine body side, and a compact and simplified grounding structure can be realized using a structure for preventing the front door from drooping.

  As shown in FIGS. 4 and 5, the sagging prevention member 8 is composed of an insert 20 made of a synthetic resin molded product and a leaf spring 21 made of an elastic metal plate such as phosphor bronze. Both are integrated by incorporating 21 into the insert 20. The insertion body 20 is formed with a holding plate portion 20a that is screwed and fixed to the back surface of the front door 3, and a protruding portion 20b that extends in a tapered shape from the central portion of the holding plate portion 20a toward the rear. A boss 20c projects from the lower center of the holding plate portion 20a. The protruding portion 20b has a hollow structure in which the holding plate portion 20a side is opened, and a rectangular opening 20d is formed in the bottom surface of the protruding portion 20b. A storage recess 20e is formed at the bottom entrance of the protrusion 20b, and the storage recess 20e extends from the holding plate 20a to the opening 20c. Further, as shown in FIG. 6, a rib 20f extending in a plate shape in the vertical direction is formed on the inner back side of the projecting portion 20b, and a gap is secured between the lower end of the rib 20f and the opening 20d. ing.

  The leaf spring 21 has a mounting plate portion 21a whose lower end is bent in an L-shape, a flat plate portion 21b extending in a direction orthogonal to the upper end of the mounting plate portion 21a, and protrudes downward in a cantilever shape from the flat plate portion 21b. The contact piece 21c is formed, and the contact piece 21c is formed in a substantially V shape with the flat plate portion 21b as a fixed end. A positioning hole 21d is formed in the mounting plate portion 21a. By inserting the positioning hole 21d into the boss 20c of the insertion body 20, the mounting plate portion 21a can be positioned at a predetermined position of the holding plate portion 20a. It has become. The flat plate portion 21b is disposed inside the protruding portion 20b of the insertion body 20, and the flat plate portion 21b is positioned at a predetermined position in the protruding portion 20b by inserting the tip portion into the lower end of the rib 20f. . The contact piece 21c protrudes downward from the opening 20d, and the protruding amount of the contact piece 21c protruding from the opening 20d is defined by elastically contacting the free end of the contact piece 21c with the inner bottom surface of the storage recess 20e. Yes.

  When the plate spring 21 having such a shape is incorporated in the insert body 20, the flat plate portion 21b is inserted into the inside from the open end of the projecting portion 20b, and the mounting plate portion 21a is aligned with the positioning hole 21d on the boss 20c. May be superimposed on the holding plate portion 20a. As a result, the tip of the flat plate portion 21b enters the lower end of the rib 20e and is positioned, and the contact piece 21c passes through the opening 20d and protrudes downward from the protruding portion 20b, as shown in FIG. A unit product of the sagging prevention member 8 in which the insertion body 20 and the leaf spring 21 are integrated can be obtained. Then, by fixing the holding plate portion 20a of the insert 20 and the mounting plate portion 21a of the leaf spring 21 to the back surface of the front door 3 using a plurality of screws (not shown) in such a unit product state. 2, the sag prevention member 8 protrudes from the back surface of the front door 3 and faces the receiving member 7 fixed to the front surface of the main body frame 2. At that time, the conductive plate 30 is attached to the back side of the front door 3 so as to surround the opening 3a, and the sag prevention member 8 is fixed to the back side of the front door 3 to thereby attach the plate portion of the leaf spring 21. 21 a is connected to a part of the conductor plate 30.

  In the pachinko machine P according to this embodiment, since the main body frame 2 is closed with respect to the machine frame 1 and the front door 3 is closed with respect to the main body frame 2 in the normal state, The game board and electronic devices cannot be touched. In this case, as shown in FIG. 6C, the protrusion 20 b of the insert 20 formed of synthetic resin is the lower front surface of the main body frame 2 among the sagging prevention members 8 fixed to the lower back side of the front door 3. Since it contacts on the guide part 7a of the receiving member 7 fixed to the side, it can prevent reliably that the front door 3 hangs down with dead weight. Further, in the closed state of the front door 3, the contact piece 21 c of the leaf spring 21 protruding downward from the opening 20 d of the protruding portion 20 b is elastically contacted on the guide portion 7 a of the receiving member 7. Alternatively, the charged static electricity can be grounded from the conductor plate 30 to the main body frame 2 side via the leaf spring 21 and the receiving member (ground plate) 7. In addition, the contact piece 21c formed in a cantilever shape on the flat plate portion 21b of the leaf spring 21 is deflected in a direction away from the inner bottom surface of the storage recess 20e by contacting the guide portion 7a. Upon receipt, the contact piece 21c is in elastic contact with the guide portion 7a of the receiving member 7 with a large contact pressure. Therefore, even if a player hits or shakes the front door 3 and a large external force is applied, the contact piece 21c of the leaf spring 21 is less likely to separate from the guide portion 7a of the receiving member 7 due to the external force. A reliable ground path can be ensured.

  Then, when the front door 3 is opened with respect to the main body frame 2 in order to eliminate ball clogging or the like occurring in the game board, as shown in FIGS. 6 (b) to 6 (a), the initial opening operation is performed. After the lower surface of the protruding portion 20 b slides forward on the guide portion 7 a of the receiving member 7 in the stage, the sag prevention member 8 is separated from the receiving member 7. At this time, since the lower surface of the protruding portion 20b formed of synthetic resin slides on the guide portion 7a of the receiving member 7 made of a metal plate, the sliding of both is smooth and the front door 3 is smoothly opened. can do. Further, the contact piece 21c of the leaf spring 21 tends to elastically return in the direction (downward) protruding from the opening 3a by separating from the receiving member 7, but in this case, the free end side of the contact piece 21c is the inner bottom surface of the storage recess 20e. Since the position of the contact piece 21c is restricted so as not to move any more at the time of contact, the free end side of the contact piece 21c is caught by an operator or the like during the opening operation of the front door 3 and is inadvertently deformed. Can be prevented.

  When the front door 3 is closed again with respect to the main body frame 2 after the ball clogging or the like is eliminated, the drooping prevention member 8 is engaged with the receiving member 7 through the reverse procedure. That is, when the drooping prevention member 8 approaches the receiving member 7 in accordance with the closing operation of the front door 3, first, as shown in FIG. 6A, the lower surface on the front end side of the protruding portion 20b is the guide portion 7a of the receiving member 7. Get on the near side. Next, when the front door 3 is further rotated in the closing direction, as shown in FIGS. 6B to 6C, the lower surface of the protruding portion 20b slides on the guide portion 7a toward the back side. The contact piece 21c of the leaf spring 21 comes into contact with the guide portion 7a and is elastically deformed. Also in this case, since the lower surface of the projecting portion 20b formed of synthetic resin slides on the guide portion 7a made of a metal plate, the sliding of both of them becomes smooth and the front door 3 can be closed smoothly. it can. Further, in the closed state of the front door 3, the contact piece 21c of the leaf spring 21 is elastically contacted on the guide portion 7a, so that static electricity generated or charged on the front door 3 from the conductor plate 30 to the leaf spring 21 and the receiving member (ground plate). ) 7 can be grounded to the main body frame 2 side.

  As described above, in the pachinko machine (game machine) P according to this embodiment, when the front door 3 is closed with respect to the main body frame (game machine main body) 2, Among the fixed sag prevention members (insert 20 and leaf spring 21) 8, the protruding portion 20b of the insert 20 formed of synthetic resin is on the guide portion 7a of the receiving member 7 fixed to the lower front side of the main body frame 2. Therefore, the front door 3 can be reliably prevented from drooping downward due to its own weight. When the front door 3 is opened and closed with respect to the main body frame 2, the lower surface of the projecting portion 20b formed of synthetic resin slides on the guide portion 7a of the receiving member 7 made of a metal plate. The movement is smoother than that between metals, and the front door 3 can be opened and closed smoothly. Further, in the closed state of the front door 3, the contact piece 21 c of the leaf spring 21 protruding downward from the opening 20 d of the protruding portion 20 b is elastically contacted on the guide portion 7 a of the receiving member 7. The charged static electricity can be grounded from the conductor plate 30 via the leaf spring 21 and the receiving member (grounding plate) 7 to the main body frame 2 side, and a compact and simplified ground using the structure for preventing the front door 3 from drooping. A structure can be realized.

  Further, the contact piece 21c is formed in a cantilever manner on the flat plate portion 21b of the leaf spring 21, and the housing 20 is formed in the insert 20 so as to surround the free end side of the contact piece 21c. When the front door 3 is closed, the free end side of the contact piece 21c is elastically contacted with the inner bottom surface of the storage recess 20e so that the position of the contact piece 21c is regulated. Can be prevented from being inadvertently deformed.

  In the above embodiment, the pachinko machine P in which the integrated front door 3 provided with the transparent plate 4 and the operation handle 16 is pivotally supported on the main body frame 2 so as to be openable and closable has been described. The present invention can also be applied to a pachinko machine of a type divided into a door and a lower door. In this case, the above-described drooping prevention structure may be applied at least to the lower door side.
