Then, the engagement between each flange 24 and each holding frame engagement fitting 13 is released. Thereby, the transparent plate holding frame 3 can be opened. At this time, even if the operating rod 18 moves upward, the first and second upward locking members 22a and 22b are biased upward, and the first and second upward locking members 22a and 22b The frame engagement fittings 12 and 12 remain engaged, and the upper end surfaces 31a of the first and second upward locking members 22a and 22b are only separated from the horizontal pressing portion 45 of the operating rod 18. Therefore, the engagement state between the first and second upward locking members 22a and 22b and the machine frame engagement fittings 12 and 12 is not released.

  When the transparent plate holding frame 3 is opened to the front side, the key is returned to the original position. As a result, the operating rod 18 is moved downward to the original position, and the first to third downward locking members 21a, 21b, and 21c are also moved by urging and returned to the original position. Further, the upper end surfaces 31a of the first and second upward locking members 22a and 22b are in contact with the horizontal pressing portions 45 of the operating rod 18. The opened transparent plate holding frame 3 is pushed to the main body frame 2 side as it is, so that the upper end edge of each holding frame engaging bracket 13 has a flange portion 24 of the first to third downward locking members 21a, 21b, 21c. It contacts the front edge of the. When viewed from the side surface, that is, the side surface of the pachinko gaming machine P, the front end edge of the flange piece portion 24 is inclined so as to gradually descend downward as it advances backward. Therefore, when the upper end edge of the holding frame engagement fitting 13 comes into contact with the inclined surface 24a of the hook piece 24, the first to third downward locking members 21a, 21b, 21c are pushed up, and finally the first One to three downward locking members 21a, 21b, 21c and the respective holding frame engagement fittings 13 are automatically engaged.

  Next, for example, when opening the main body frame 2 with the transparent plate holding frame 3 closed, the key is inserted into the key hole 52 of the cylinder lock 48 from the front side of the pachinko gaming machine P and rotated in the clockwise direction as described above. Let Accordingly, as shown in FIG. 7C, the cam piece 51 rotates in the same direction together with the lock shaft 48a of the cylinder lock 48, and the upper claw 51a of the cam piece 51 pushes the cam receiving piece 46 downward. In addition, the operating rod 18 moves downward together with the cam receiving piece 46, and the horizontal pressing portions 45, 45 push down the first and second upward locking members 22a, 22b on the rear end side of the operating rod 18, so 32 is disengaged from each machine frame engagement fitting 12. Thereby, the main body frame 2 can be opened. At this time, even if the operating rod 18 moves downward, the first to three downward locking members 21a, 21b, 21c are biased downward, and the first to three downward locking members 21a, 21b. 21c and the holding frame engagement fittings 13, 13, 13 are still engaged, and the lower end surface 23a of the first to third downward locking members 21a, 21b and the horizontal push-up portions 40, 40 of the operating rod 18 are retained. And only the horizontal step 43 and the protrusion 25 are separated. Therefore, the engagement state between the first to third downward locking members 21a, 21b, and 21c and the holding frame engagement fittings 13, 13, and 13 is not released.

  When the main body frame 2 is opened to the front side, the key is returned to the original position. As a result, the operating rod 18 moves upward to the original position, and the first and second upward locking members 22a and 22b move by urging and return to the original position. Further, the lower end surface 23a of the first or second downward locking members 21a and 21b and the horizontal push-up portion 40 and the horizontal step portion 43 of the operating rod 18 are in contact with the protrusion 25. The opened main body frame 2 is pushed to the machine frame 1 as it is, so that the lower end edge of each machine frame engagement fitting 12 is brought to the front end edge of the flange part 32 of the first and second upward locking members 22a and 22b. Abut. When viewed from the side surface, that is, the side surface of the pachinko gaming machine P, the front end edge of the hook piece portion 32 is inclined so as to gradually rise upward as it advances forward. Therefore, the first and second upward locking members 22a and 22b are pushed down when the lower end edge of the machine frame engagement fitting 12 comes into contact with the inclined surface 32a of the flange portion 32, and finally the first and second locking members 22a and 22b are pushed down. The upward locking members 22a and 22b are automatically engaged with the machine frame engagement fittings 12 and 12, respectively.

  In the present invention, the first to three downward locking members 21a, 21b and 21c and the first and second upward locking members 22a and 22b are respectively arranged at predetermined positions with respect to the operating rod 18. The two are engaged with each other in the same vertical plane in the front-rear direction. The front-rear direction includes not only a plane orthogonal to the front surface of the main body frame 2 but also a case where it is slightly inclined left and right when viewed in plan. However, since the problem is in the locking device A and in the range corresponding to the open side end surface 4b of the game board 4, at least the locking member included in the range in the operation rod 18 and the front-rear direction. Therefore, they may be engaged within the same vertical plane. The range corresponding to the open side end surface 4b of the game board 4 is a range that does not interfere with the enlargement when the game board 4 is enlarged rightward and upward when the pachinko gaming machine P is enlarged as it is from the front. say. For that purpose, the side surface 4b on the open side of the game board 4 when enlarged is projected onto the locking device A side, and the operating rod 18, first to three downward locking members 21a, 21b, 21c and the first The parts included in the shadows of the one or two upward locking members 22a and 22b need to be arranged in the same plane. Therefore, for example, in the third downward locking member 21c located at the lower end portion of the locking device A and located outside the range, it does not matter if it is not arranged in the same vertical plane as the operating rod 18. Become. Also, the torsion coil spring 28 as the elastic means may be formed thin in a planar manner only for the torsion coil spring 28 located at least in a range corresponding to the open side end surface 4b of the game board 4.

  As described above, the pachinko gaming machine P according to the present invention is provided with the locking device A on the opening side, and gradually spreads outward as the opening side wall 2a in the main body frame 2 is viewed in plan. Since the locking device A is arranged so as to be inclined at the same angle in the same direction as the side wall 2a of the main body frame 2 in a plan view, it is inclined at a predetermined angle with respect to the surface orthogonal to the front surface of the main body frame 2. It is a part where the game board 4 is arranged, and a space margin is created on the open side. Therefore, the game board 4 can be further expanded within a limited range. Further, in the pachinko gaming machine P in which the game board 4 is mounted from the front side, the side wall 2a on the open side of the storage recess in which the game board 4 is disposed is inclined at a predetermined angle so as to gradually spread outward as it advances to the front side. Therefore, it is easy to install the game board 4. Further, from the opening 9 on the front surface of the transparent plate holding frame 3, the side wall 2a of the main body frame 2 is moved away from the edge of the opening 9, and at the same time, the locking device A is also moved away from the opening. It becomes difficult to get.

  At this time, the locking device A is formed in, for example, a vertically long and flat plate shape, and the plate surface thereof is arranged along the front-rear direction. The main body frame 2 or the transparent plate holding frame 3 is always urged by the torsion coil spring 28 and the main body frame 2 or the frame 2 or the like is interlocked against the urging of the torsion coil spring 28 as the operating rod 18 moves up and down. The first to third downward locking members 21a, 21b, 21c and the first and second upward locking members 22a, 22b for unlocking the transparent plate holding frame 3, and at least in the locking device A In the range corresponding to the side end surface 4b on the open side of the game board 4, the operating rod 18, the first to three downward locking members 21a, 21b, 21c and the first and second upward locking members 22a, 22b are front and rear. In the same vertical plane in the direction Since the arrangement, the thickness of the locking device A can be correspondingly narrowed thin. Therefore, the game board 4 can be further expanded.

At this time, by the torsion coil spring 28 so as to bending only One Shin contraction song a wire as an elastic means, together with the tilting side walls 2a and locking device A on the open side of the body frame 2 as described above The operating rod 18, the first to third downward locking members 21a, 21b, 21c and the first and second upward locking members 22a, 22b overlap with the arrangement in the same vertical plane in the front-rear direction, and the locking device Further thinning of A is possible. Therefore, the thickness of the locking device A can be reduced as much as possible. As this type resilient means may be a spring which is adapted to shrink only One Shin bending piece of wire, for example, a filigree spring.

  At this time, since the locking device A is pivoted around the pivotal support portion O of the main body frame 2 in a state where the locking device A is attached to the outer surface of the side wall 2a of the main body frame 2, the locking device A is accompanied with the opening / closing operation of the main body frame 2. Should not hit the inner surface 1b of the vertical frame 1a on the same side of the machine frame 1. For this reason, in consideration of a range in which the main body frame 2 cannot be supported and cannot be rotated, the degree of inclination of the locking device A is such that the shaft support portion O of the main body frame 2 is set as shown in FIG. When the arc trajectory C as the center is drawn, the arc trajectory C having the maximum radius is drawn in a range not contacting the inner surface 1b of the vertical rod 1a on the one side of the machine frame 1, and the locking device A uses the arc trajectory C having the maximum radius. Is set within a range that does not protrude outward, and the mounting position of the locking device A is determined.

  The operating rod 18 in the locking device A is also zigzag so that the recess 41 provided at the front edge, the notch 42 and the pair of recesses 44 provided at the rear edge do not overlap each other in the front-rear direction. The width of the operating rod 18 in the front-rear direction is reduced as much as possible. Thereby, the width | variety of the front-back direction of locking device A itself can be narrowed, and it is easy to install in the restricted space inside the said circular arc locus C. Further, the maximum radius of the arc locus C can be set farther from the shaft support portion O, and the game board can be further expanded.

  In the pachinko gaming machine P according to the present invention, the first to third downward locking members 21a, 21b, 21c and the first and second upward locking members 22a, 22b as the locking members on the locking device A side. Are provided with hook pieces 24 and 32, respectively, and the machine frame engaging metal fitting 12 and the holding frame engaging metal fitting 13 as latching members on the machine frame 1 and the transparent plate holding frame 3 side are engaged with the hook piece portions 24 and 32, respectively. The configuration is such that it can be matched. In contrast, a hook piece fixed to the machine frame engaging metal 12 and the holding frame engaging metal 13 is provided, and the first to three downward locking members 21a, 21b, 21c on the locking device A side are provided. The flange portions 24 and 32 of the first and second upward locking members 22a and 22b are deleted, and the first and third downward locking members 21a, 21b and 21c and the first locking members 21a, 21b and 21c on the locking device A side are removed. You may make it latch on the 1 or 2 upward locking members 22a and 22b. Further, the locking device used in the present invention is not limited to the one described above. For example, an operating rod is disposed so that the plane cross-section is U-shaped and faces the side end surface of the game board. The present invention can also be applied to a locking device provided with a latch member that can move up and down in a plane parallel to the surface to be operated in the left-right direction. Furthermore, although the case where the locking device A was attached to the main body frame 2 has been described, the present invention can be applied even to a gaming machine where the locking device A is attached to the machine frame 1 or the transparent plate holding frame 3. it can. Furthermore, although a cylinder lock that uses a key as a lock is shown, it goes without saying that the present invention can also be applied to a gaming machine including a locking device incorporating a so-called electronic lock that does not use a key.
