Further, the door frame protrusion 60 and the game board protrusion 61 are interlocked with each other, but the lock of the game board 10 is not released even when the lock of the transparent plate door frame 4 is released. The “locking amount” here indicates the degree of overlap between the locking portions 60 a and 61 a and the locking holes 20 and the receiving portions 28, and the locking portions 61 a of the game board protrusion 61 and the game board 10. It means the depth of engagement with the engaging portion 28 and the depth of engagement between the locking portion 60a of the door frame protrusion 60 and the locking hole 20 of the transparent plate door frame 4. The gaming board protrusion 61 is formed in a tapered shape as a guide part 70 that facilitates engagement with the engaging part 28 when the gaming board 10 is mounted, and the rear end of the leading end abuts the front surface of the gaming board 10. It is formed in an upward bowl shape having a locking portion 61a in contact therewith. The distance between the support plate 51c of the mounting board 51 and the locking portion 61a of the game board protrusion 61 is set to be larger than the thickness of the game board 10, and the game board 10 is located between the support plate 51c and the locking portion 61a. Is held with a slight play. By this play, when the cylinder lock 52 is unlocked and the operating rod 55 is slid, the contact friction between the locking portion 61a and the game board 10 is reduced, and the unlocking operation by the cylinder lock 52 is facilitated. be able to. In addition, a guide part 70 is bent and provided on the game board protrusion 61 positioned above, so that the operating rod 55 can be operated from the front side by using the planar guide part 70 as an operation piece 71. I have to. Thus, by forming the guide portion 70 in a planar shape, the contact area between the guide portion 70 and the engagement portion 28 is increased when the game board 10 is mounted, and the engagement portion 28 that contacts the guide portion 70 is partially formed. Thus, the operating board 55 can be reliably operated by the game board 10 without being worn, and the game board protrusion 61 can be easily engaged with the engaging part 28. Further, an operation piece or an operation lever for operating the operating rod 55 from the front side may be provided separately from the game board protrusion 61. In the embodiment, a plurality of game board protrusions 61 are provided above and below, but the number of game board protrusions 61 is not limited, and the game board 10 is locked and fixed at one place. Also good. Further, the door frame protrusion 60 is not limited to a bowl shape, and a bowl-shaped projection piece that protrudes toward the game board 10 side is provided on the transparent plate door frame 4 side, and the bowl-like projection is provided on the operating rod 55. You may make it provide the latching piece or latching hole which a protrusion latches.

  The cylinder lock 52 is inserted into a through hole formed in the reinforcing plate 51b of the mounting substrate 51 and fixed by screwing a flange portion 52a to the reinforcing plate 51b, and restricting the rotation of the cam plate 53 to the flange portion 52a. As means, stoppers 72a and 72b are projected. The cam plate 53 has a front frame unlocking claw 73 that is locked to the locking step portion 62 of the locking rod 54 and a door frame unlocking claw 74 that is locked to the recessed notch locking portion 68 of the operating rod 55. Then, the operating force is transmitted to the locking rod 54 or the operating rod 55 by operating the key K, and the machine frame protrusion 58 or the door frame protrusion 60 is slid in the unlocking direction. At this time, even if the cylinder lock 52 is rotated by the operation of the key K, the locking plate 54 and the operating rod 55 will not slide further because the cam plate 53 is restricted by the stoppers 72a and 72b. In addition, the mechanism plate 12 and the game board 10 are not disengaged. In this embodiment, the mechanism plate protrusion 59 can release the engagement with the engagement hole 34 and open the mechanism plate 12 by sliding the locking rod 54 by hand. Further, the game board protruding piece 61 is configured so that the operation board 55 can be slid by hand to release the engagement with the receiving portion 28 so that the game board 10 can be detached from the game board holding frame 11. Yes. In the embodiment, the spring 56 for urging the locking rod 54 in the locking direction and the spring 57 for urging the operating rod 55 in the locking direction are separately provided. However, the locking rod 54 and the operating rod 55 are respectively provided in the locking direction. For example, one end of a spring is fixed to the locking rod 54 so that the locking rod 54 and the operating rod 55 are urged in the locking direction with respect to each other. It is also possible to reduce the number of parts by sharing one elastic member so that is fixed to the operating rod 55.

  The locking device 5 configured in this manner exposes the tip of the cylinder lock 52 to the front surface of the front frame 3, attaches the reinforcing plate 51b to the back surface of the front frame 3, and attaches the mounting piece 51e above the mounting plate 51a. Is attached to the upper end of the upper frame 11a of the game board holding frame 11, and the lower attachment piece 51e is attached to the lower end of the lower frame 11b and screwed.

  Next, the locking effect | action of the front frame 3 and the transparent plate door frame 4 by the locking apparatus 5 of the said structure is demonstrated. First, in order to close and lock the transparent plate door frame 4 with respect to the front frame 3, when the free end of the transparent plate door frame 4 is pushed to the front frame 3 side, the locking hole 20 of the transparent plate door frame 4 opens the door. The operating rod 55 is moved downward against the urging force of the spring 57 by coming into contact with the tip inclined portion of the frame projection piece 60. Then, the door frame protrusion 60 is engaged with the locking hole 20 by the return elasticity of the spring 57, so that the transparent plate door frame 4 is securely closed with respect to the front frame 3 as shown in FIG. Retained. In order to close and lock the front frame 3 with respect to the machine frame 2, when the free end of the front frame 3 is pushed toward the machine frame 2, the upper and lower machine frame protrusions 58, 58 are attached to the bracket 14 of the machine frame 2. , 14 and the locking rod 54 is moved up against the bias of the spring 56. The machine frame projections 58 and 58 are engaged with the receiving brackets 14 and 14 by the return elasticity of the spring 56, so that the open side of the front frame 3 is substantially in close contact with the machine frame 2 as shown in FIG. Occluded.

  Next, the unlocking operation of the locking device 5 will be described. First, to unlock the front frame 3, when the cam plate 53 is rotated in the arrow direction of FIG. The operating force of the cam plate 53 is transmitted to the locking rod 54 against the bias of the spring 56 to slide the machine frame projecting pieces 58 and 58 upward. Then, as shown in the chain line in FIG. 15, the engagement between the machine frame projecting pieces 58, 58 and the receiving brackets 14, 14 is released, and the front frame 3 can be easily opened. At this time, the cam plate 53 abuts against the stopper 72a to prevent further rotation, and the locking rod 54 only moves up within the unlocking range of the machine frame projection 58, that is, within the range of the loose insertion slot 65. Even if the headed pin 66 is moved upward at the lower end of the loose insertion long hole 65, the mechanism plate protruding piece 59 is not moved up, and the mechanism plate protruding piece 59 and the engagement hole 34 are engaged. Is not released and the mechanism plate 12 is not unnecessarily opened. To unlock the transparent plate door frame 4, the cam plate 53 is rotated in the direction of the arrow in FIG. 13B (the direction opposite to the unlocking direction of the front frame 3) by unlocking the key K. Then, the door frame unlocking claw 74 is engaged with the notch engaging portion 68 of the operating rod 55, and the operating force of the cam plate 53 is transmitted to the operating rod 55 against the urging force of the spring 57, thereby the door frame. The projecting piece 60 is slid downward. Then, as shown in the chain line in FIG. 14, the engagement between the door frame protrusions 60 and the locking holes 20 is released, and the transparent plate door frame 4 can be easily opened. At this time, the game board protrusion 61 is also interlocked, but the cam plate 53 is in contact with the stopper 72b and is prevented from further rotation, and the operating rod 55 does not slide any more, and the door frame protrusion 61 Since the locking amount of the locking portion 61a of the game board protrusion 61 is larger than the locking portion 60a of the piece 60, the engagement with the game board 10 is not released.

  Next, locking and unlocking operations on the free end side of the mechanism plate 12 will be described. If the free end side is closed so that the mechanism plate 12 is in close contact with the game board 10 with the mechanism plate 12 being opened and closed by the hinge mechanism 13, the tip inclined side of the downward-facing hook-like mechanism plate projection piece 59 is provided. Comes into contact with the engaging hole 34 and further presses the mechanism plate 12 toward the game board 10, the mechanism plate protrusion 59 is moved into the guide long hole 64 by the inclined side against the bias of the springs 56 and 67. Move up along. At this time, since the headed pin 66 is located at the upper end of the loose insertion slot 65, the locking rod 54 is also moved up at the same time and moved up beyond the unlocking range of the machine frame projection piece 59. Since the opening and closing of the plate 12 is performed with the front frame 3 open as shown in FIG. 16, there is no problem even if the locking piece 54 moves up and the machine frame protrusion 58 moves up. Absent. When the mechanism plate 12 comes into close contact with the game board 10, the mechanism plate protrusion 59 engages with the engagement hole 34 by the return elasticity of the springs 56 and 67, and the mechanism plate 12 comes into close contact with the back surface of the game machine 10. Fixed.

  In order to open the mechanism plate 12, first, the front frame 3 is opened by the unlocking operation of the cylinder lock 52, and the operation portion 63 of the locking rod 54 located behind the front frame 3 is operated to lock the mechanism plate 12. When the flange 54 is slid in the unlocking direction (upward in the embodiment) against the bias of the springs 56 and 67, the lower end of the loose insertion long hole 65 becomes the headed pin 66 as shown in FIG. The mechanism plate projecting piece 59 is moved up by contact. Then, the engagement between the mechanism plate protrusion 59 and the engagement hole 34 is released simultaneously in the vertical direction, and the mechanism plate 12 can be opened in this state.

  Next, mounting of the game board 10 will be described. In order to mount the game board 10 on the game board holding frame 11, with the transparent plate door frame 4 opened, the left side of the game board 10 is placed between the support plate 46 and the elastic piece 48 from the front side of the installation area 22. Is inserted into the holding portion 75. At this time, as shown in FIG. 11, the tip of the elastic piece 48 is located in the bent piece 47 and is formed on the inclined surface, so that the side edge of the game board 10 is guided to support the support plate 46 and the elastic piece. The elastic piece 48 can securely press and fix one side end of the game board 10 to the holding portion 75. When the right side of the game board 10 is pushed into the installation area 22, the notched end of the engaging part 28 comes into contact with the tapered guide part 70 of the game board protrusion 61. The operating rod 55 moves downward together with the game board protrusion 61 against the bias of the spring 57. When the rear surface of the game board 10 comes into contact with the support plate 51 c, the operating rod 55 is restored by the bias of the spring 57, and the locking portion 61 a of the game board protrusion 61 is engaged with the end of the engagement portion 28. Then, the game board 10 is simply mounted on the game board holding frame 11, and the elastic piece 51e of the mounting board 51 is elastically pressed to the position of the side surface of the game board 10 which is divided into approximately three equal parts. Shaking of the direction is reliably prevented. At this time, the portion where the elastic piece 48 and the elastic piece 51e abut against the game board 10 are notched, and the elastic piece 48 and the elastic piece 51e are fitted into the notch when the game board 10 is mounted. The upward movement of the game board 10 may be restricted by 51e abutting on the upper part of the notch and restricting the upward movement. In addition, the operating rod 55 moves down beyond the unlocking range of the door frame protrusion 60, but the transparent plate door frame 4 has already been opened and thus has no effect. Then, when the transparent plate door frame 4 is closed, the press member 21 provided on the transparent plate door frame 4 elastically presses the surface of the game board 10, so that the game board 10 is firmly attached to the game board holding frame 11. Retained. When the game board 10 is mounted from the front side on the rear periphery of the upper frame part 11a and the lower frame part 11b, a support piece as a support part for positioning and supporting the rear surface of the game board 10 is directed to the center of the opening. You may make it stand up.

  Next, in order to remove the game board 10 from the game board holding frame 11, first, the cylinder lock 52 is rotated by the key K and the transparent board door frame 4 is unlocked. The free end of the frame 4 is opened. The unlocking operation of the cylinder lock 52 causes the game board protrusion 61 to move down at the same time. However, the locking portion 61a of the game board protrusion 61 depends on the amount of the locking portion 60a of the door frame protrusion 60. Since the locking amount of the game board 10 is set to be larger, the engagement between the game board protrusion 61 and the engagement portion 28 of the game board 10 is not released, and the game board 10 is held unnecessarily. It does not come off from the frame 11. When the operating piece 71 is operated and the operating rod 55 is moved downward in the opened state of the transparent plate door frame 4, the game board protruding piece 61 is interlocked to release the engagement with the engaging portion 28. In this state, the game board 10 can be removed from the game board holding frame 11 by pulling the right end of the game board 10 forward and pulling the left end of the game board 10 out of the holding portion 75 between the support plate 46 and the elastic piece 48. .

  In this embodiment, the amount of rotation of the cylinder lock 52 is restricted by the stopper 72b so that the operating rod 55 moves within the unlocking range of the door frame protrusion 60. However, the rotation restriction by the stopper 72b is eliminated. It is also possible to unlock the game board 10 by further rotating the cylinder lock 52 after unlocking the transparent plate door frame 4. At this time, an unlocking confirmation protrusion is provided in place of the stopper 72b, and the cam plate 53 comes into contact with the protrusion when the transparent plate door frame 4 is unlocked to temporarily turn, so that the game board 10 is not unlocked at once. It is preferable that the cam plate 53 is rotated stepwise. In addition, a restriction piece that protrudes from the back surface of the transparent plate door frame 4 so as to be positioned below the game board protrusion 61 may be provided to restrict the downward movement of the game board protrusion 61. This restricting piece faces the lower side of the game board protrusion 61 with the transparent plate door frame 4 closed, and the game board protrusion even if the operating rod 55 is unlocked by the cylinder lock 52. 61 is prevented from coming into contact with the regulating piece and sliding further. When the transparent plate door frame 4 is opened, the restriction is released, and the unlocking operation of the game board protrusion 61 can be performed by the cylinder lock 52. Moreover, you may make it add the function of the holding member 21 which presses the above-mentioned game board 10 to this control piece.

  As described above, the side surface of the game board 10 is held in contact with and held by the locking device 5 and the hinge mechanism 13, so that the game machine can be compared with a pachinko machine in which the side surface of the game board 10 has been held by the holding frame. The board 10 can be enlarged in the horizontal direction to widen the game area 10a, and it can cope with the increase in the size of a display device that is desired to improve the interest of the game in recent years. Further, since the locking means for holding the game board 10 on the game board holding frame 11 is provided in the locking device 5 such as the transparent plate door frame 4, the number of parts such as a fixture for fixing the game board 10 is reduced. And cost reduction can be achieved. At this time, by forming the tip of the game board protrusion 61 as the locking means in the tapered guide portion 70, the game board 10 can be easily mounted simply by pushing it into the game board installation area 22, The workability for installing the game board 10 is improved.

  In the embodiment, one side of the game board 10 is clamped and held by the holding portion 75 between the support plate 46 and the elastic piece 48, and the other side is provided with the locking device 5 on the locking board 5. However, it is not limited to the fixing means, but one side of the game board 10 is pivotally supported by the connecting member 41 of the hinge mechanism 13 and the other side is provided separately. You may make it attach with a game board fixing tool, In that case, it is preferable to form an attaching part so that a game board fixing tool may be previously mounted | worn to the attachment board | substrate 51. FIG. At this time, the shaft support side of the game board 10 is also described by the hinge mechanism 13 of the mechanism plate 12. However, when the game board 10 is rotatably mounted, the axis of the shaft pin is positioned in the shaft hole. It is preferable to provide a guide portion for positioning so as to efficiently mount the game board 10.

  In FIG. 18, the locking portion 61a of the game board protrusion 61 is formed as a plate-like locking surface, and the front surface of the game board 10 is pressed against the locking surface and the contact friction resistance with the game board 10 is increased. The Example which provided the light friction means to reduce is shown. Specifically, a support roller 76 is provided as a light friction means, and the bearing piece 78 of the support roller 76 is erected by opening substantially the center of the locking surface. The shaft 61 is rotatably supported in the sliding direction 61. The support roller 76 may be resinous or metal. Thus, by providing the support roller 76 on the locking surface 61a, the game board 10 can be reliably pressed and locked to the installation area 22, and also when the transparent plate door frame 4 is opened with a key, The contact resistance with the game board 10 can be reduced. The contact position of the support roller 76 when the game board protrusion 61 and the game board 10 are engaged, that is, the distance from the end of the receiving portion 28 to the contact position of the support roller 76 is determined by the transparent plate door frame 4. The unlocking operation range is set so that the support roller 76 is positioned so as not to be detached from the engaging portion 28 even when the transparent plate door frame 4 is unlocked. For this reason, it is possible to smoothly perform the unlocking operation of the transparent plate door frame 4 without applying a load, and it is not necessary to provide the pressing member 21 for pressing the game board 10. Further, even if a bearing is provided on the locking surface 61a as a light friction means instead of the support roller 76, the contact resistance with the game board 10 can be reduced, and the same effect as the support roller 76 can be obtained. it can.

  In the embodiment, the game board protruding piece 61 and the door frame protruding piece 60 are integrally provided on the operating rod 55, and the locking directions of the locking portions 60a and 61a are the same direction. The locking direction of the protruding piece 60 may be opposite to the locking direction of the gaming board protruding piece 61, and it is vertically supported by pivotally supporting the intermediate portion of the door frame protruding piece 60 with respect to the mounting substrate 51. By providing one end of the door frame protruding piece 60 to the operating rod 55, the locking portions 60a and 61a can be locked in the reverse direction by sliding the operating rod 55 in the same direction. Can be. That is, when the operating rod 55 is moved, the door frame protrusion 60 rotates upward to release the engagement with the locking hole 20 of the transparent plate door frame 4, and further, the operating rod 55 is moved downward. The engagement between the game board 10 and the game board protrusion 61 can be released. Further, by providing the door frame protrusion 60 so as to be rotatable, the amount of rotation of the door frame protrusion 60 can be adjusted by changing the pivotal support position, and the operation rod 55 can be moved with a small amount of movement. Many of the locking portions 60a can be moved. Therefore, the locking portion 61a of the game board protruding piece 61 may be slightly larger than the amount of release movement of the locking portion 60a of the door frame protruding piece 60, and the gaming board protruding piece 61 can be made compact. .

  Further, the length of the locking portion 60a of the door frame protrusion 60 and the length of the locking portion 61a of the game board protrusion 61 are made different to each other, so that the transparent plate door frame 4 is a game board. The engagement portion 60a and 61a of the door frame projection piece 60 and the game board projection piece 61 are formed to have the same length. The length of the engaging portion 28 of the game board 10 that can be locked by the locking portion 61a is greater than the length of the locking hole 20 of the transparent plate door frame 4 that can be locked by the locking portion 60a of the door frame protrusion 60. Even if it is formed long, the respective locking amounts can be made different, and the transparent plate door frame 4 can be unlocked first, and then the engagement of the game board 10 can be released. At this time, the door frame protrusion 60 itself may be regulated so that the locking portion 60a of the door frame protrusion 60 is not locked more than a predetermined amount. It is preferable to provide a restricting means such as a step-like restricting portion for restricting the stopping amount, and the engaging portion 60a is restricted by the restricting portion so as not to be locked more than a predetermined amount.

  In the embodiment, the game board 10 is mounted from the front side of the pachinko machine 1, but it can also be mounted from the rear side of the game board holding frame 11. At this time, the support plates 46 and 51c provided on the locking device and the hinge mechanism may be provided on the front side of the game board installation area 22.

  Further, the locking device 5 is not limited to the embodiment, and the locking device for the front plate 6 provided with the upper ball tray 7 is provided even if the locking device for locking the open end of the plate-like member 38 is provided. It may be. In this way, by providing the locking device 5 with the door locking devices that are attached to the pachinko machine 1 so as to be freely opened and closed, the assembly process can be simplified and the space can be used effectively. Moreover, the locking device 5 may perform only opening and closing of the conventional front frame 3 and transparent plate door frame 4. Further, in the embodiment, the unlocking operation is performed by the cylinder lock 52, but an operating device is provided that operates according to a command from the hall computer without directly using the cylinder lock 52 and directly operates the locking rod 54 and the operating rod 55. Alternatively, the locking device 54 and the operating device 55 may be operated by remotely operating the operating device to open the front frame 3 or the transparent plate door frame 4.
