Description

The present invention relates to a pachinko machine in which a plurality of control boards are arranged on the back side of a game board.

  Conventionally, on the back of the pachinko machine, there are a main control board that controls the entire game operation, an effect control board that controls the game effects, a sound / light control board that controls effects by sound and effects, Many control boards are provided, such as a power supply board that supplies power to the control board and other members that require power.

  In particular, in recent years, an effect control board and a sound / light control board that are different for each model are attached to the back surface of the game board to be integrated with the game board, while a main control board that can be used in common with a plurality of models. In many cases, the power supply board or the like is attached to the lower side of the game board on the back side of the base frame so that when the model is exchanged, only the game board is exchanged.

  By the way, these control boards are in the back of the pachinko machine in a state where they are accommodated in the board cases so that they will not be damaged due to contact with other members during transportation or illegally operated from the outside. It is arranged. A connection cable such as a power supply cable or a signal line connected to the control board is connected to the control board inside the case through an opening formed in the board case from the outside of the board case.

  Thus, although the control board of the pachinko machine is housed and protected in the board case, the connection cable connected to the control board is exposed to the outside of the board case. Therefore, there is a possibility that the connection cable may be damaged when the pachinko machine falls or contacts other members during transportation.

  Therefore, as described in Patent Document 1, for example, by attaching a cover member that covers substantially the entire back surface of the game board together with the board case, the connection cable exposed to the outside of the board case is protected. There is a pachinko machine that was made.

  However, in the pachinko machine as described in Patent Document 1, since only the back surface of the game board is covered, the connection cable connected to the control board disposed below the game board is not protected.

  Some of the upper surface of the substrate case is provided with a heat radiating vent to suppress heat generation of the control substrate. Therefore, when the cover member is disposed above the board case disposed below the game board, the bottom surface of the cover member is positioned immediately above the vent hole of the substrate case and covers the vent hole. There is a possibility that the heat dissipation efficiency of the substrate case may be lowered. In particular, the power supply board is also often disposed below the game board, but the power supply board is one of the control boards that are likely to become high temperature, and reducing the heat dissipation efficiency is a big problem.

Japanese Utility Model Publication No. 6-75573

  Here, the present invention has been made in the background as described above, and the problem to be solved is that it is connected to the control board while preventing a decrease in the heat dissipation efficiency of the board case as much as possible. It is an object of the present invention to provide a pachinko machine having a novel structure capable of effectively protecting connecting cables.

That is, according to the present invention, the control board for controlling the game operation is disposed in the central area where the game board is disposed and the lower area below the central area in a state where the control board is accommodated in the board case. In the pachinko machine, a liquid crystal display is arranged in the central area, and a main control board case containing a main control board and a power supply board case containing a power supply board are arranged in a lower area. An auxiliary board case containing an auxiliary board is disposed between the display, the main control board case, and the power board case, and the liquid crystal display, the main control board, the power board, and the auxiliary board are connected by a connection cable. set with, while providing the upper surface to the vent holes of the board case of the main control board and the power board is disposed in the lower region, an opening in the upper portion of the back of the board case of the main control board and the power supply board are , The connected connection cable to the main control board and the power board through such openings with allowed to expose to the outside, is disposed to the lower end of the openable attached a cover member with respect to the rear surface side of the base frame in the lower region By overlapping the upper part of the main control board and the power supply board on the back side of the board case, the lower end of the cover member covers the extended portion from the opening of the connection cable, and the upper part is lower than the lower end of the cover member. It is characterized by covering the liquid crystal display, the auxiliary substrate case, and the connection cable .

  If it does in this way, the extension part from the opening part of the connection cable connected to the control board arrange | positioned under the game board can also be protected effectively. In particular, in the present invention, since the opening of the board case disposed below the game board is provided in the upper part of the back surface of the case, the extension dimension of the cover member downward can be kept small. Thus, the rigidity of the cover member can be advantageously ensured and the handling is facilitated. In addition, the center area | region in this invention means the position from the upper end of the game board in the back surface side of a base frame to a lower end, and a lower area means the area | region below the center area in the back surface side of a base frame. Further, the upper surface of the board case means a surface that extends substantially perpendicular to the spreading direction of the game board and faces upward when mounted on the back side of the base frame of the board case. It is not limited to the surface located at the upper end of the entire substrate case. In addition, the back surface of the board case refers to a surface that extends substantially parallel to the spreading direction of the game board and faces the back side when the base frame of the board case is attached to the back side. In the present invention, it is sufficient that at least a portion extending from the opening of the connection cable is covered with the cover member, and includes a mode in which a part of the connection cable is exposed from the cover member. A mode in which the entirety is covered with a cover member is more preferably employed.

  Furthermore, according to the present invention, since the lower end portion of the cover member is superimposed on the back surface of the board case disposed below the game board, the bottom surface of the cover member is positioned above the upper surface of the board case. There is no. This prevents the board case from closing the vent hole formed on the upper surface of the board case, and can reduce the possibility of reducing the heat dissipation efficiency of the board case disposed below the game board. .

  In addition, the opening and closing of the cover member in the present invention includes an aspect in which the entire cover member is opened and closed by being attached to and detached from the back side of the base frame. Therefore, the cover member may be opened and closed without being separated from the back side of the base frame by a hinge mechanism or the like, or the entire cover member may be removable using screws, ny latches, etc. Also good.

  The main set 48 hinged to the base frame 16 so as to be opened and closed by the bearings 112 and 114 and the shafts 120 and 122 is closed so as to be superimposed on the back surface of the base frame 16. In the member 52, insertion holes 126a, 126b, 126c, and 126d that penetrate the frame member 52 are provided in portions that overlap the mounting holes 124a, 124b, 124c, and 124d, respectively (see FIG. 3). Particularly in the present embodiment, the mounting holes 124a, 124c, and 124d are formed through the rear end face of the cylindrical portion 128 that protrudes rearward as shown in FIG. 7 as an example of the mounting hole 124a. On the other hand, a cylindrical outer fitting portion 130 protruding forward is formed on the front surface of the insertion holes 126a, 126c, and 126d. The inner diameter of the outer fitting portion 130 is slightly larger than the outer diameter of the cylindrical portion 128. Thus, the outer fitting portion 130 is fitted on the cylindrical portion 128 in a state where the main set 48 is closed.

  Then, with the main set 48 closed, the ny latch 132 is inserted from the back surface of the insertion holes 126a, 126b, 126c, 126d and attached to the attachment holes 124a, 124b, 124c, 124d. The frame 16 is fixed in a closed state.

  The ny latch 132 in this embodiment is constituted by a grommet 134 and a plunger 136 as schematically shown in FIG. The grommet 134 is an integrally molded part in which a disc portion 138 having a disc shape and a tip portion 140 divided into four in the circumferential direction are connected by a cylindrical portion 142. 140 can be opened and closed. An insertion hole 144 that penetrates the disc portion 138 and the cylindrical portion 142 is formed on the central axis of the grommet 134. On the other hand, the plunger 136 is formed with an operation portion 146 having a truncated conical shape whose diameter is reduced in the axial intermediate portion, and an action portion 148 extending in the axial direction from the operation portion 146 with a substantially cylindrical shape. Note that the distal end portion and the proximal end portion of the action portion 148 are slightly larger in diameter, and the diameter size of the distal end portion and the proximal end portion of the action portion 148 is substantially equal to the inner diameter dimension of the insertion hole 144. .

  The action portion 148 of the plunger 136 is inserted into the insertion hole 144 of the grommet 134 from the rear in the axial direction. When the action portion 148 is pushed in the tip direction, the tip portion 140 of the grommet 134 is inserted. Is pushed from the inside.

  The ny latch 132 having such a structure is inserted into the insertion hole 124a from the back surface of the frame member 52 as shown in FIG. 7 as an example of the insertion hole 124a, and the tip portion 140 of the grommet 134 is inserted into the mounting hole 124a. Is done. Then, when the plunger 136 is pushed in the distal direction, the distal end portion 140 is opened and held in an open state, so that the frame member 52 and the cylindrical portion 128 are disposed between the distal end portion 140 and the disc portion 138. The end face is clamped. Thereby, the frame member 52 is fixed in a state of being pressed against the base frame 16.

  Here, as shown in FIG. 5, since the central window 50 is provided in the main set 48, when the main set 48 is closed, for example, a liquid crystal display 150 arranged on the back surface of the game board 14 is provided. Further, members such as the effect control board 152 and the sound / light control board 154 are positioned in the central window 50 of the main set 48 so as not to interfere with the main set 48. Further, particularly in the present embodiment, the shaft holes 116 and 118 constituting the hinge mechanism have a long hole shape extending in the front and back direction of the base frame 16. Thus, when opening the main set 48, first, the entire main set 48 is moved rearward along the shaft holes 116 and 118 so that the shafts 120 and 122 are positioned at the rear ends of the shaft holes 116 and 118. In this state, that is, the main set 48 can be rotated with a predetermined distance from the base frame 16. Thus, when the main set 48 is opened, it does not interfere with the liquid crystal display 150 or the like disposed on the back surface of the game board 14. Similarly, when closing the main set 48, after the shafts 120 and 122 are positioned at the rear ends of the shaft holes 116 and 118, the main set 48 is rotated in the closing direction in advance, and then the main set 48 is closed. Since the whole can be brought close to the base frame 16, the main set 48 is not superimposed on the liquid crystal display 150 and the like from an oblique direction, and the possibility of interference with each other is reduced.

  Further, particularly in the present embodiment, a mounting hole 156 having a structure similar to that of the mounting hole 124a and the like is formed on the lower right side of the through hole 46 in the base frame 16 (see FIG. 2). At the same time, an insertion hole 158 having the same structure as the insertion hole 126 a is provided in the frame member 52 at a position overlapping the mounting hole 156 in the thickness direction of the frame member 52. Then, with the main set 48 closed, the insertion hole 158 is overlapped with the attachment hole 156, and the nai latch 160 having the same structure as the above-described nai latch 132 is attached from the back of the attachment hole 156. The portion of the set 48 where the opening 72 is formed is fixed so as to be pressed against the base frame 16. As a result, the frame member 52 can be made difficult to bend by pressing a portion in the vicinity of the opening 72 that is easily bent due to being away from the bearings 112 and 114 and the ny latch 132 to the base frame 16.
