Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board mounting structure of a pachinko machine for mounting a circuit board on which various electronic parts or electric parts are mounted on the back side of a game board in the pachinko machine.

[0002]

2. Description of the Related Art In a pachinko machine which is a game machine, a circuit board for controlling a game state and the like is attached to the back side of the game board. In recent years, the number of circuit boards attached to a pachinko machine tends to increase with the progress of electronic control. In order to cope with such an increase in the number of circuit boards, the pachinko machine has a state in which some circuit boards such as a main board are stacked on another circuit board such as a relay board along its thickness direction, Some are attached to the back side of the game board. The circuit board in a pachinko machine is usually connected to another circuit board such as a relay board or a device such as a display device to be controlled by a harness made of a flexible printed board or the like. When the circuit board is replaced or the circuit board is replaced due to a failure, the upper circuit board must be removed from the back side of the game board to attach or detach the harness or consumable parts to the relay board, resulting in consumable parts or a cause of failure. It may happen that the replaced circuit board cannot be replaced.

[0003]

SUMMARY OF THE INVENTION In consideration of the above facts, an object of the present invention is to provide a board mounting structure for a pachinko machine in which a circuit board can be easily attached to and detached from the back side of a game board.

[0004]

According to the board mounting structure of the pachinko machine described in claim 1, the claw member provided on one of the board setting base and the leg is L-shaped at the tip. A bent hooking portion is formed on the board, and it is possible to bend and deform from a predetermined hooking position to a release position. Further, a hooked member provided on the other side of the board setting base and the leg is a board setting base. When the holding member is placed at a predetermined mounting position on the upper side, the holding member is hooked by the hooking portion at the hooking position, and the claw member is flexibly deformed from the hooking position to the releasing position and released from the hooking portion. Thus, by avoiding the interference between the claw member and the hooked member, if the holding member to which the circuit board is attached is placed at the mounting position on the board setting table, the claw member and the hooked member are mutually attached. It is possible to connect and attach the holding member to the board setting table. Also, when the holding member is attached to the substrate setting table, if the claw member is flexibly deformed from the hooking position to the releasing position, the connection between the claw member and the hooked member is released, and the holding member becomes the substrate setting table. The circuit board can be easily attached to and detached from the board setting table via the holding member.

Further, since the holding member is formed with legs at both ends in the width direction, other circuit boards and parts such as various devices are arranged in an area of the board setting table facing the holding member. Since it is possible to secure a space that can be used, the space on the substrate setting table can be efficiently used. At this time, since the holding member can be easily attached / detached to / from the substrate setting table, it is possible to easily perform work or replacement for the component arranged in the area of the substrate setting table facing the holding member.

According to the board mounting structure of the pachinko machine described in claim 2, the hooked portion bent in an L-shape is provided at the tip of the claw member provided on one of the board setting base and the leg. Further, a hooking member formed on the other side of the board setting base and the legs is movably supported between the hooking position and the releasing position with respect to the claw member by an operation from the outside, and on the board setting base. When the holding member is placed at the predetermined mounting position and moves from the release position to the hooking position, the hooked portion is hooked and connected to the claw member, and the holding member is attached to the substrate setting table. In this state, when moving from the hook position to the release position, the holding member to which the circuit board is attached is placed at the attachment position on the board setting table by releasing from the hooked portion and releasing the connection with the claw member. The locking member to the release position. If moved to the hooking position, the claw member and the hooking member can be connected to each other and the holding member can be attached to the substrate set base, and if the hooking member is moved from the hooking position to the release position, Since the connection between the claw member and the latching member is released and the holding member can be removed from the board setting table, the circuit board can be easily attached to and removed from the board setting table via the holding member.

Since the holding member is formed with legs at both ends in the width direction, other circuit boards and various devices can be arranged in a region of the board setting table facing the holding member. Because you can secure the possible space,
The space on the board setting table can be used efficiently. At this time, since the holding member can be easily attached / detached to / from the substrate setting table, it is possible to easily perform work or replacement for the component arranged in the area of the substrate setting table facing the holding member.
