Description

[0001]
[Industrial application fields]
This invention also relates to the lower frame of the game board frame that is the framework so that fits game board comprising a firing target area of the game balls in the pachinko game machine.
[0002]
[Prior art]
Pachinko machines are designed to play a game ball while firing it into a desired game area of the game board.To that end, a ball cage that fires a game ball on the game board frame, a launch motor as its drive source, The mounting base plate is preliminarily equipped with an operation handle that adjusts the hitting force at the same time as starting the launch motor, and the mounting base plate equipped with these is a wooden front frame or a lower frame made of synthetic resin that constitutes a game board frame On the other hand, a structure in which the firing rail is independently attached via a support member has been common.
[0003]
Then, in order to attach the mounting base plate to the wooden front frame or the synthetic resin lower frame constituting the game board frame, the mounting base plate is attached by a number of screws or the like. Therefore, since the mounting structure is a screw or the like, not only the assembly process is complicated, but the same screw hole has to be used when screwing again when replacing the launcher for convenience. As a result, there is a problem that the fixing effect of screwing is lost. In addition, in the conventional structure in which the mounting base plate and the firing rail are separately mounted, it is necessary to check and adjust the ball flying condition.
[0004]
[Problems to be solved by the invention]
In the conventional launcher mounting structure, the frame body is made of wood or synthetic resin, so it cannot be said that the product accuracy is good. In the case of a synthetic resin product, the accuracy of the mounting position does not necessarily coincide with the designed position due to sink marks or the like generated in the molding process stage.
[0005]
Even when mounting the mounting plate of the launcher on a wooden or synthetic resin frame, not only need to be screwed in many places, but also because there are many parts made of different materials, it takes effort to obtain and manage them. In addition, in the case of screwing, there is a tendency for deviation to occur, and it is difficult to obtain reliable accuracy. Furthermore, since there are many parts made of different materials, there is a problem that they are not suitable for recycling.
[0006]
In view of the above circumstances, the present invention is easy to manufacture and assemble, obtains reliable accuracy, and is easy to attach and remove the launcher, and is suitable for recycling in pachinko machines . The purpose was to provide the lower frame of the board frame .
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is a member of left and right side frames, an upper frame, and a lower frame that are framed as a game board frame so that a game board that becomes a target area for launching a game ball is fitted. The launcher is a lower frame that is mounted by mounting the launcher base plate, and is widely injection-molded with a magnesium alloy in a plate shape so that the launcher base plate can come into contact with the launcher base plate. An opening for mounting a fitting convex portion with a built-in drive motor of the device on the plate is fitted, and an opening for mounting a control device for controlling touch sensitivity adjustment and hitting strength adjustment on the upper portion of the attachment hole Extending the space area, projecting an edge rib projecting around the periphery of the integrally formed hole of the mounting hole and the opening space area, and further, the base plate at the lower end of the area where the launcher base plate is attached To support it at the lower end, A support rib that is sandwiched in a shape of the shape is projected, and above the support rib, a plurality of relief holes composed of a large-diameter hole and a small-diameter hole are provided with a head that projects from the launcher base plate. A lower frame of a game board frame in a pachinko gaming machine is provided, which is formed and arranged in a reverse snow shape so that the hozo can be hooked downward.
[0008]
[Operation]
