In FIG. 9, the outer frame 11 is not shown.

  A vertically long base frame 247 constituting the locking device 24 includes a mounting plate 2 and a support plate 3, which are integrally formed in a substantially L-shaped cross section. As shown in FIG. 2, the locking device 24 has its mounting plate 2 attached to the back side of the main body frame 12 in the vertical direction.

  A plurality of mounting holes are formed in the mounting plate 2, and rectangular insertion holes are formed in the upper and lower portions. When the front door frame 13 is closed, the door frame collar portion enters the insertion hole. Further, guide pins 2a to 2c for guiding sliding of door frame locking members 161 to 163, which will be described later, are respectively mounted on the mounting plate 2 below the insertion hole.

  A standing wall portion 249 is erected perpendicularly to the rear side along the longitudinal direction at the outer end of the mounting plate 2 (on the non-connection side with the support plate 3). The standing wall portion 249 has a role of preventing the wire from reaching the inside of the base frame 247 where the sliding rod 248 is provided when a wire or the like is inserted from the gap between the outer frame 11 and the main body frame 12. Yes.

  The standing wall portion 249 is formed with notches 249a and 249b that are notched in an arc shape in the vicinity of guide pins 4a and 5a that fix the flange members 4 and 5 to a sliding rod 248 described later. . The notches 249a and 249b are provided in this way because the standing wall 249 interferes with the punch in the manufacturing process in which the tips of the guide pins 4a and 5a are deformed using the punch and coupled to the sliding rod 248, respectively. This is to prevent it from happening.

  Inside the support plate 3, a sliding rod 248 as a moving member is slidably arranged up and down. The flange members 4 and 5 as the locking members (first locking members) provided on the upper and lower portions of the base frame 247 come to slide in conjunction only when the sliding rod 248 moves upward. Yes. The sliding rod 248 is formed in a band shape from a metal plate.

  Guide holes are provided in the upper and lower portions of the sliding rod 248, and two rectangular engaging portions 248c and 248d with which a cam plate 8 described later can be engaged are formed above the lower guide holes. Has been. When the main body frame 12 is unlocked, when the key K is inserted and the key operation is performed clockwise with respect to the cylinder lock 91, a first engagement convex portion 8a of the cam plate 8 described later is engaged with the engagement portion 248d. Match. Further, when the front door frame 13 is unlocked, the second engaging convex portion 8b of the cam plate 8 is engaged with the engaging portion 248c when a key operation is performed counterclockwise with respect to the cylinder lock 91.

  The upper and lower flange members 4 and 5 have triangular heads, and the lower ends of the tips are engaging portions. As shown in FIG. 3, guide pins 4 a and 5 a are fixed to the upper and lower flange members 4 and 5, and the guide pins 4 a and 5 a are provided on the upper and lower portions of the support plate 3. Each is inserted into an oval guide hole in an engaged state. Further, the eaves members 4 and 5 are guided by guide portions 3 c and 3 d provided on the upper and lower portions of the support plate 3. That is, the flange members 4 and 5 are supported by the guide pins 4a and 5a and the guide portions 3c and 3d so as to be slidable up and down within a predetermined range.

  The guide pins 4a and 5a are respectively inserted into the two guide holes of the sliding rod 248, and coil springs 9b and 9d are hung between the flange members 4 and 5 and the mounting plate 2, respectively. The members 4 and 5 are always pulled downward. The guide pins 4 a and 5 a are in contact with the lower edge portions of the two guide holes 248 of the sliding rod 248 and the two guide holes of the support plate 3.

  Accordingly, as the sliding rod 248 slides upward, the flange members 4 and 5 also move upward in conjunction with each other. On the other hand, each of the eaves members 4 and 5 is independently movable upward, and when the upper and lower eaves members 4 and 5 are moved upward with a wire or the like (when an illegal act is performed) The wire must be hooked on both hook members 4 and 5 and pulled up.

  A deformed hole for mounting the cylinder lock 91 is formed in the widened portion at the lower portion of the mounting plate 2, and a mounting bracket portion is formed corresponding to the deformed hole. The mounting bracket portion is formed by notching a part of the mounting plate 2 and bending the upper and lower notch pieces inwardly in a hook shape. And the cylinder lock 91 is being fixed in the attachment bracket part in the state inserted in the irregular hole of the base frame 247. More specifically, the cylinder lock 91 has a flange at a tip portion thereof, and the flange is screwed to the mounting bracket portion in a state where a part of the main body of the cylinder lock 91 is inserted inside the base frame 247. It is fixed.

  A cam plate 8 having a first engagement convex portion 8 a and a second engagement convex portion 8 b is fixed to the lock shaft of the cylinder lock 91. When the cam plate 8 is rotated clockwise by the key operation, the first engagement convex portion 8a of the cam plate 8 is engaged with the engagement portion 248d of the slide rod 248, and the slide rod 248 is slid upward. Move. Thereby, the eaves members 4 and 5 slide upward. At this time, the engagement between the flange members 4 and 5 and the metal fittings 164 and 165 on the outer frame 11 side is released, and the main body frame 12 is unlocked. Therefore, the locking / unlocking mechanism of the main body frame 12 with respect to the outer frame 11 is formed by the flange members 4 and 5, the sliding rod 248, the cam plate 8, the cylinder lock 91, and the like.

  On the other hand, when the cam plate 8 is rotated counterclockwise by the key operation, the second engaging convex portion 8b of the cam plate 8 is engaged with the engaging portion 248c of the sliding rod 248, and the sliding rod 248 is The door frame locking members 161 and 162 slide downward and slide downward. At this time, the engagement between the door frame locking members 161, 162, and 163 and the door frame collars on the front door frame 13 side is released, and the front door frame 13 is unlocked. Accordingly, the door frame locking members 161, 162, 163, the sliding rod 248, the cam plate 8, the cylinder lock 91, etc. form a locking / unlocking mechanism for the front door frame 13.

  Next, the configuration of the receiving metal fitting 164 will be described. The metal fitting 164 is formed by cutting and bending a substantially rectangular metal plate (for example, a cold-rolled steel plate having a thickness of about 1 to 2 mm). As shown in FIGS. 164a, a locked portion 164b, and a shielding portion 164c.

  The mounting portion 164a occupies approximately half of the rear side of the receiving metal fitting 164, has two screw holes 164d and 164d, and is in close contact with the inner side surface 11b on the right side of the outer frame 11 by two wood screws 164s. (See FIG. 8).

  The locked portion 164b is parallel to the front end surface 11c of the outer frame by cutting and raising a substantially central portion of the receiving metal fitting 164 by a predetermined length (for example, about several tens of millimeters) perpendicularly (left and right direction) to the mounting portion 164a. It is a rectangular piece-like part formed with a flat surface, and the collar member 4 is locked. In the locked portion 164b, the tip end portion 164e is bent at a right angle to the rear side in order to prevent the collar member 4 from being detached by an external force in the horizontal direction. In addition, a protruding portion 164p is formed on the locked portion 164b by punching the base end portion in a triangular pyramid shape to the rear side. The protruding portion 164p is provided to improve the strength of the locked portion 164b, and when an external force is applied in the front-rear direction (that is, the B line direction in FIG. 7A and the opposite direction). There is an effect that deformation hardly occurs.

  The shielding part 164c occupies substantially half of the front side of the metal fitting 164, is a parallel surface that is stepped to the right (outside) with respect to the mounting part 164a, and is a surface parallel to the outer frame inner surface 11b. It is. Then, substantially half of the shielding part 164c protrudes forward from the front end surface 11c of the outer frame, and the notch part 249a of the standing wall part 249 is viewed from the inside in a state where the main body frame 12 is closed with respect to the outer frame 11. It has a role to close. Note that the projection length from the front end surface 11c of the outer frame is greater than the depth of the notch 249a and less than the height of the standing wall 249 so that the shield 164c can block the entire notch 249a (for example, The length in the vertical direction is set to be equal to or longer than the length of the notch 249a (for example, about 30 mm).

  The metal fitting 165 is the same component as the metal fitting 164, and the relationship between the metal fitting 165, the flange member 5 and the notch 249b is the same as the relationship between the metal fitting 164, the flange member 4 and the notch 249a. Since they are the same, detailed description thereof will be omitted.

  Next, a description will be given of the operational effects related to locking of the pachinko machine 10 of the present embodiment configured as described above.

  When the main body frame 12 in the pachinko machine 10 is closed with respect to the outer frame 11, the upper and lower flange members 4 and 5 of the locking device 249 are independently resisted by the tensile force of the coil springs 9b and 9d. It moves upward while hitting the side metal fittings 164, 165, and then returned by the tensile force of the coil springs 9b, 9d to be locked to the metal fittings 164, 165, as shown in FIGS. It becomes the locked state shown. In this locked state, even if a wire or the like is illegally inserted from the gap between the main body frame 12 and the outer frame 11, the standing wall portion 249 reliably prevents the wire or the like from reaching the sliding rod 248. In addition, the cutout portions 249a and 249b of the standing wall portion 249 are closed on the inner side by the shielding portions 164c and 165c of the receiving metal fittings 164 and 165, so that it is possible to reliably reach the hook members 4 and 5 such as wires. Be blocked. Here, FIG. 10 shows a state in which the periphery of the flange member at the time of locking is shown in a top view, and shows that access to the flange member 4 and the sliding rod 248 from the outside by a wire or the like is blocked. Therefore, it is impossible for an unauthorized person to move the hook member 4 or 5 in the unlocking direction with a wire or the like, or to hook the wire or the like on the sliding hook 248 and slide it upward to unlock it. Unauthorized unlocking of the main body frame 12 is completely prevented.

  When unlocking the main body frame 12, the lock shaft of the cylinder lock 91 is rotated clockwise with the key K inserted into the key hole of the cylinder lock 91, and the cam plate 8 is rotated. Then, the first engagement convex portion 8a of the cam plate 8 engages with the engagement portion 248d of the slide rod 248, and the slide rod 248 slides upward. Then, the upper and lower flange members 4 and 5 that are interlocked only when the sliding rod 248 is raised are moved upward, whereby the engagement of the outer frame 11 with the receiving brackets 164 and 165 is released, and the main body frame 12 can be opened. (See FIG. 9B).

  On the other hand, when the front door frame 13 in the main body frame 12 is closed with respect to the main body frame 12, the door frame flanges protruding rearward of the front door frame 13 pass through the insertion holes of the main body frame 12, and then the mounting plate 2 enters the base frame 247 from each insertion hole formed in the door 2, and enters each locking hole of the door frame locking members 161-163. And after sliding the door frame locking members 161-163 against the tensile force of the coil springs 9a, 9c, 9e, the door frame locking members 161-163 are pulled by the tensile force of the coil springs 9a, 9c, 9e. Returns upwards. Thereby, a door frame collar part is latched by the edge of each latching hole, and the front door frame 13 will be in a locked state.

  When unlocking the front door frame 13, if the lock shaft of the cylinder lock 91 is turned counterclockwise with the key K inserted into the key hole of the cylinder lock 91 and the cam plate 8 is rotated, The second engaging convex portion 8b engages with the engaging portion 248c of the sliding rod 248, and the sliding rod 248 slides downward against the tensile force of the coil springs 9a, 9c, 9e. Then, the upper and lower door frame locking members 161 to 163 that are interlocked only when the sliding rod 248 slides downward slides downward, whereby each door frame flange portion of the front door frame 13 and each locking hole The edge is disengaged and the front door frame 13 is opened.

  As is clear from the above detailed description, according to the gaming machine 10 of the present embodiment, the locking device 24 includes the locking device 24 that locks the main body frame 12 that is opened and closed with respect to the outer frame 11. , A cylinder lock 91 that is unlocked by a key K, and a hook member 4 that is locked to and detached from the locked portions 164b and 165b of receiving brackets 164 and 165 as receiving members provided inside the outer frame 11. 5 and a sliding rod 248 as a key unlocking transmission mechanism that transmits the operation of the cylinder lock 91 according to the unlocking operation of the key K to the rod members 4 and 5 to be detached from the locked portions 164b and 165b. A vertical wall 249 erected on the outside of the sliding rod 248, and the receiving brackets 164 and 165 cover the notches 249 a and 249 b of the vertical wall 249 with the body frame 12 closed. Shield part 164c, 1 5c is provided. Therefore, the insertion of a wire or the like from the gap between the main body frame 12 and the outer frame 11 can be reliably prevented, and the unlocking action of the locking device 24 based on an unauthorized external operation can be prevented.

  In the present embodiment, since the shielding portion 164c (165c) is integrally formed with the locked portion 164b (165b) by a metal plate, the shielding portion 164c (165c) and the locked portion 164b (165b) are formed. Can be attached to the outer frame 11 at the same time, and the number of assembling steps does not increase as compared with the prior art.

  Further, the shielding portion 164c (165c) and the locked portion 164b (165b) are integrally formed by cutting up a part of the metal plate (the receiving metal fitting 164 (165)) constituting the shielding portion 164c (165c). The formed structure can be realized easily and reliably.

  Moreover, since the shielding part 164c (165c) is provided only around the notch part 249a (249b) of the standing wall part 249, the weight increase can be suppressed and the cost can be reduced.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 11A and 11B are diagrams showing the receiving metal fitting 364 according to the second embodiment, in which FIG. 11A is a front view of the mounting posture to the outer frame 11, and FIG. 11B is a view taken along line C in FIG. (C) has each shown the D line arrow enlarged view in (a). FIG. 12 is a perspective view showing the upper periphery of the receiving metal 364 of the outer frame 11 in the second embodiment. FIG. 13 is a right side view when the pachinko machine 310 of the second embodiment is locked. FIG. 14 is an enlarged view showing the periphery of the flange member 4 when viewed from above when the second embodiment is locked. FIG. 15 is a top view of the periphery of the flange member 4 at the time of locking according to the second embodiment, and shows a state in which access to the flange member 4 and the sliding rod 248 from the outside by a wire or the like is blocked. Yes.

  The metal fitting 364 is formed by cutting and bending a metal plate (for example, a cold-rolled steel plate having a thickness of about 1 to 2 mm) that has a long shape that is long in the vertical direction. Mounting portion 364a having the same length as the direction, locked portions 364b and 364c to which the hook members 4 and 5 are respectively locked to the upper and lower portions of the mounting portion 364a, and extending forward from the mounting portion 364a Thus, a shielding part 364d having a difference in height and having the same length as the longitudinal direction of the standing wall part 249 and a plurality of screw holes 364e are provided. That is, in the receiving metal fitting 364a of this embodiment, the shielding part 364d is provided so as to overlap the entire longitudinal direction of the standing wall part 249.

  The attachment portion 364a is a portion that occupies substantially half of the rear side of the receiving metal fitting 364, has six screw holes 364d, and is attached in close contact with the inner side surface 11b on the right side of the outer frame 11 by six wood screws 364s. (See FIG. 12).

  The to-be-latched portion 364b cuts and raises a portion corresponding to the flange member 4 of the receiving bracket 364 by a predetermined length (for example, about ten and several millimeters) perpendicularly (left and right direction) to the mounting portion 364a. It is a rectangular piece-like part in which a surface parallel to the surface 11c is formed, and the collar member 4 is locked. In the locked portion 364b, the tip portion 364f is bent at a right angle to the rear side in order to prevent the collar member 4 from being detached by an external force in the horizontal direction. Further, a protruding portion 364p is formed on the locked portion 364b by punching out the base end portion in a triangular pyramid shape to the rear side. The protruding portion 364p is provided to improve the strength of the locked portion 364b, and has an effect that deformation hardly occurs when an external force is applied in the front-rear direction.
