In the present embodiment, as shown in FIG. 4, one shaft member is provided in a state where the upright piece protruding forward from the mounting base 15 is vertically penetrated, and a portion protruding upward from the upright piece 32 is provided with a glass frame. The first hinge mechanism 23A for axially attaching the lower part of one side 2 functions as a fixed shaft member 33, and the part protruding downward from the standing piece 32 is attached to the upper part of the one side of the open / close panel 3 It functions as the fixed shaft member 33 of the one hinge mechanism 23B. However, the fixed shaft member 33 may be used separately for the glass frame 2 and the open / close panel 3 or may have different positions of the fixed shaft member.
In addition, the part shown with the code | symbol 34 in FIG. 4 is the wall part for the foreign material insertion prevention which stood up from the inner edge of the attachment base 15, and functions as a foreign material approach prevention member of this invention.

  The second hinge mechanism 24B that pivotally attaches one side lower part of the open / close panel 3 to the front frame 6 so as to be openable and closable is a hinge mechanism having a movable shaft, and is provided below the shaft support member 30 so as to be movable up and down. The movable shaft member 40 that rotates together with the open / close panel 3, the movable side bearing hole 41 that is provided on the front frame 6 side and into which the distal end of the movable shaft member 40 is inserted, and the distal end of the movable shaft member 40 is the movable side bearing. The coil spring 42 is configured as a biasing member that biases downward into the hole 41.

  Specifically, as shown in FIG. 4, an upright piece 43 is erected forward at the lower end of the mounting base 15 located at the lowermost side of the opening 5 of the front frame 6. The movable side bearing hole 41 is opened.

  As shown in FIGS. 5 to 8, the shaft support member 30 is formed by bending a metal plate into a crank-shaped cross section to form a lower step surface 30a, a connection surface 30b, and an upper step surface 30c, and protruding from the lower step surface 30a. 43, a fixing hole 44 is formed, and an operation opening 45 is formed by notching from the shaft-attached side of the upper step surface 30c to the lower step surface side, and an upper end portion of the upper step surface 30a is bent forward. The fixed bearing hole 31 is opened, and a bent piece 47 in which the lower end portion of the upper contact surface 30a is bent forward and a bent piece 48 in which the lower end opening edge of the operation contact portion 45 is bent forward are provided. The support hole 50 for the movable shaft is opened on a straight line, and a plurality of fixing holes 51 are opened above and below the operation opening 45. The step between the lower step surface 30a and the upper step surface 30c has a dimension that can accommodate (accommodate) an operation portion of the movable shaft member 40 described later. Further, a part of the shaft support member 30 located between the bent pieces 47 and 48 and located on the distal end side of the movable shaft member 40 bulges forward, and a spring receiving portion of the movable shaft member 40 described later has no problem. A bulging portion 52 is formed so as to be able to move up and down.

  In the embodiment of the drawings, the movable shaft member 40 is an L-shaped shaft in which the upper half portion (rear end portion) of the shaft member is bent in the lateral direction and the bent portion serves as a lateral projecting portion that also serves as the operation portion 55. There is a flange-shaped spring receiving portion 56 at a position slightly retracted upward from the tip. The length of the operation portion 55 is set slightly longer than the dimension from the movable shaft support hole 50 to the edge on the lower step surface 30a side of the operation opening 45.

  When the movable shaft member 40 is mounted on the shaft support member 30, that is, as shown in FIG. 7, the tip portion is placed in the lower movable shaft support hole 50 with the coil spring 42 wound around the shaft portion. Is inserted into the upper movable shaft support hole 50, the movable shaft member 40 is pushed downward by the urging force of the coil spring 42, so that the operation portion 55 is bent at the upper movable shaft support hole 50. The tip protrudes from the lower movable shaft support hole 50. Further, since the operation unit 55 is set to the above-described length, the tip of the operation unit 55 can be engaged (contacted) with the edge of the operation opening 45.

  When the shaft support member 30 to which the movable shaft member 40 is attached is fixed to the back side of the open / close panel 3 with screws 57, the operation unit is accommodated between the back surface of the open / close panel 3 and the shaft support member 30, as shown in FIG. The operating portion 55 accommodated in the empty portion 58 is movable up and down, but is opened and closed by being sandwiched between the back surface of the shaft support member 30 and the base 26 of the opening and closing panel 3. The panel 3 cannot be freely rotated. Accordingly, the shaft support member 30 and the back surface of the open / close panel 3 function as an engaging portion, and when the open / close panel 3 is opened / closed, either the shaft support member 30 or the back surface of the open / close panel 3 operates as the engage portion. Abutting on the portion 55, the movable shaft member 40 and the open / close panel 3 can be rotated together.

  As shown in FIG. 5, the stopper 60 protrudes above the operation portion 55 on the back surface of the open / close panel 3, so that the movable shaft member 40 is raised and the distal end of the movable shaft support hole 50. Even if the operating portion 55 is retracted to near, the operating portion 55 contacts the stopper 60 and the ascending range is restricted. The restriction does not cause the tip of the movable shaft member 40 to be detached from the movable shaft support hole 50. That is, in this embodiment, the stopper 60 functions as the stopper member of the present invention, and when the open / close panel 3 is open, the stopper 60 restricts the movable range (stroke) of the movable shaft member 40 and prevents it from coming off. is doing.

  In order to attach the open / close panel 3 having the first and second hinge mechanisms 23B and 24B to the front frame 6, first, the fixed bearing hole 31 of the first hinge mechanism 23B with the open / close panel 3 tilted slightly. The fixed shaft member 33 on the front frame 6 side is inserted therein, the operation portion 55 of the second hinge mechanism 24B is raised with a finger, and the front end of the movable shaft member 40 is retracted to move the front end toward the front frame 6 side. Positioning on the movable bearing hole 41, the movable shaft member 40 is lowered in this state, and the tip is inserted into the movable bearing hole 41.

  When the open / close panel 3 is attached to the front frame 6 in this way, the open / close panel 3 is rotatable about the fixed shaft member 33 of the first hinge mechanism 23B and the movable shaft member 40 of the second hinge mechanism 24B. When the free end side of the open / close panel 3 is pressed to the front side, the hook of the locking mechanism engages with the lock receiving portion 28 and is locked in the closed state.

  In the present invention, when the front opening / closing member such as the opening / closing panel 3 is closed, the movable shaft member 40 protrudes to a position where it abuts against the lateral protrusion of the movable shaft member 40 when moving in the direction of coming out of the movable side bearing hole 41. The movable shaft member that prevents the movable shaft member 40 from coming off and permits the movement of the movable shaft member 40 in the removal direction by rotating the lateral projecting portion together with the front surface opening / closing member when the front opening / closing member is opened. A movable range restricting member 61 is provided.

  In the present embodiment, as shown in FIGS. 4 and 5, a part of the operation portion 55 of the movable shaft member 40 stopped in the lowered state (inserted state) is obtained by cutting a part of the lower portion of the mounting base 15. A movable shaft member movable range restricting member 61 is provided so as to project upward (in a range shorter than the stroke for the distal end of the movable shaft member 40 to come out of the movable bearing hole 41).

  Therefore, when the open / close panel 3 is closed, the movable shaft member movable range restricting member 61 is positioned on the operation portion 55 to forcibly prevent the movable shaft member 40 from rising. For this reason, even if a foreign material such as a plastic plate is inserted through the gap between the opening 5 of the front frame 6 and the open / close panel 3 and the movable shaft member 40 is lifted and removed from the movable shaft side bearing hole 41, the movable shaft The member 40 is prevented from rising by the movable shaft member movable range restricting member 61, and it is possible to reliably prevent an illegal act of removing the shaft attachment side of the open / close panel 3.

  When it is necessary to remove the open / close panel 3 for maintenance of the ball supply device or the ball launcher, first, the glass frame 2 is opened and then the lock of the open / close panel 3 is unlocked, and the open / close panel 3 is opened wide and opened. State. When the open / close panel 3 is in the open state, the movable shaft member 40 rotates together with the open / close panel 3 so that the operation unit 55 deviates from the restriction of the movable shaft member movable range restricting member 61 and is allowed to move. That is, since it can freely move up and down, an operator can lift the operation portion 55 with a finger and pull out the tip of the movable shaft member 40 from the movable side bearing hole 41 as before. If the movable shaft member 40 is disengaged from the movable-side bearing hole 41, the movable shaft member 40 is lowered while pulling the lower portion of the open / close panel 3 toward the front, whereby the fixed bearing hole 31 of the shaft support member 30 is moved from the fixed shaft member 33 on the front frame 6 side. Thus, the opening / closing panel 3 can be removed from the front frame 6.

  Further, the foreign matter insertion preventing wall portion 34 provided in a state of protruding from the front frame 6 side as the foreign matter entry preventing member is on the inner side (center side) than the movable shaft member movable range restricting member 61, in other words, the front frame 6. Since it is provided on the side of the opening 5, fraudulent acts can be prevented in the event that foreign matter is inserted into the overlapping portion of the front frame 6 and the open / close panel 3 with the open / close panel 3 closed. That is, although the movable shaft member 40 is disposed at a position that may be illegally operated by an unauthorized person, the movable shaft member 40 does not operate due to the presence of the movable shaft member movable range restriction member 61. Even if a foreign object is inserted, the opening / closing panel 3 can be prevented from being removed, and the foreign object entry prevention wall part 34 protrudes. The inside can also prevent cheating by fraudsters. Therefore, it is possible to reliably prevent an illegal act due to the entry of foreign matter into the overlapping portion of the front frame 6 and the open / close panel 3.

  Furthermore, since the foreign matter insertion preventing wall portion 34 is provided so as to be adjacent to the portion of the shaft support member 30 bent in the crank shape, it is formed to be large while avoiding the operation portion 55 of the movable shaft member 40. Can do. Therefore, the entire longitudinal direction of the open / close panel 3 can be protected by the insertion preventing wall portion 34.

  The foreign matter insertion preventing wall 34 may be provided on the outside of the movable shaft member 40, for example. However, if it is provided close to the outside of the open / close panel 3, the side of the open / close panel 3 when the open / close panel 3 is opened. And the foreign matter insertion preventing wall portion 34 interfere with each other, causing an obstacle to the opening operation. If the foreign matter insertion preventing wall portion 34 is provided so as to be able to be opened, the side portion of the opening / closing panel 3 is provided. A gap is formed between the two and the function of preventing fraud by inserting foreign objects is not satisfied. It is also conceivable to provide the foreign matter insertion preventing wall 34 on the inner side near the movable shaft member 40, but the surface of the shaft support member 30 exists, and the protruding length of the foreign matter insertion prevention wall portion 34 reaches that surface. Therefore, the function for preventing foreign matter entry is satisfied to a certain extent but is incomplete. For this reason, in the present embodiment, as described above, the foreign matter insertion preventing wall portion 34 is provided so as to be adjacent to the bent portion of the shaft support member 30 having a crank shape.

  Next, the first hinge mechanism 23A for attaching one lower portion of the glass frame 2 to the front frame 6 side will be described. The first hinge mechanism 23A is a back surface of the frame body 20 of the glass frame 2 as shown in FIG. A shaft support member 30 'is fixed to the lower portion of one side with a screw, a fixed bearing hole 31' is formed in the lower portion of the shaft support member 30 ', and the fixed shaft member 33 provided on the front frame 6 side is connected to the fixed bearing hole. It is comprised so that it may fit in 31 '.

  In addition, the second hinge mechanism 24A for attaching one upper part of the glass frame 2 to the front frame 6 only has the up and down direction of the movable shaft member reversed. This is the same as the hinge mechanism 24B. That is, as shown in FIGS. 2 and 10, the shaft support member 35 is fixed to the back side of the frame body 20 with screws, the movable shaft member 40 a is placed on the shaft support member 35, and the tip is directed upward. The operation unit 55a is provided between the shaft support member 35 and the frame body 20, and the operation unit 55a is in contact with the shaft support member 30a or the frame body 20. A stopper 60a protruding from the frame body 20 is provided below the movable shaft member 40a. Then, the movable shaft member movable range restricting member 61a is provided on the front frame 6 side so as to be positioned immediately below the operation portion 55a with the glass frame 2 closed. As in the case of the second hinge mechanism 24B for the opening / closing panel 3, this movable shaft member movable range restricting member 61a is formed by cutting and raising a part of the mounting base 15. As shown in FIG. 10, a wall portion 64 that prevents the wiring 63 from being caught is provided upright on the shaft holding member 35 on the glass holding frame 21 side.

  Therefore, the glass frame 2 can be opened and closed around the fixed shaft member 33 and the movable shaft member 40a of the first and second hinge mechanisms 23A and 24A. When the free end side is pressed against the front frame 6, the hook of the locking mechanism for the glass frame can be engaged and locked with the locking receiving portion 25 provided on the back surface of the glass frame 2. In this closed state, the movable shaft member movable range restricting member 61a prevents the movable shaft member 40a from descending, so that an elongated plastic plate or the like is formed from the gap between the opening 5 of the front frame 6 and the glass frame 2. Even if it is attempted to lower the movable shaft member 40a by inserting the foreign matter, it cannot be lowered. Therefore, the illegal act from this part can be prevented effectively. When the glass frame 2 is opened, the operation portion 55a of the movable shaft member 40a is allowed to move out of the restriction range of the movable shaft member movable range restriction member 61a, so that the operator operates the operation portion 55a. Then, the movable shaft member 40a can be lowered and the tip can be pulled out from the movable bearing hole 41a. Therefore, the operator can remove the glass frame 2 as needed.

  By the way, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  For example, the front opening / closing member of the present invention is not limited to the glass frame 2 and the opening / closing panel 3, but is a member that can be opened and closed on the front frame 6 so as to close the opening 5 of the front frame 6 from the front. I just need it. Specifically, a front opening / closing panel in which the glass frame and the opening / closing panel of the present embodiment are integrated may be used.

  Further, the lateral projecting portion provided on the movable shaft member 40 is not limited to the operation unit 55, but projects in the lateral direction from the axial direction of the movable shaft member 40 and comes into contact with the movable range regulating member 61 for the movable shaft member. Anything is acceptable. For example, you may comprise by the protrusion which protrudes in the horizontal direction in the middle of the movable shaft member 40.

  Furthermore, the configuration in which the movable shaft member 40 is rotated together with the front opening / closing member is not limited to the configuration in which the lateral protrusion is accommodated in the space formed between the back surface of the front opening / closing member and the shaft support member 30, but is rotated together. Any configuration is possible as long as it can be configured. For example, the cross section of the shaft hole that supports the movable shaft member 40 may be polygonal, and the cross section of the movable shaft member 40 that penetrates the shaft hole may be polygonal. An engaging portion that engages and rotates together may be formed.

  The present invention is not limited to the pachinko gaming machine 1 and may be any gaming machine provided with a front opening / closing member in the opening 5 of the front frame 6, for example, a slot gaming machine or a sparrow ball type gaming machine. A machine may be used.
