JP 2000-157706 A

By the way, in the invention disclosed in Patent Document 1, for example, maintenance is performed from the front surface side of the back substrate box in a state where the front substrate box is rotated downward about the hinge shaft at the bottom.・ Inspecting work, inserting / removing terminal connectors of connection lines to / from various board connectors arranged on the circuit board in the back board box, or sealing part placed in the back board box It is difficult to perform the work of cutting out the substrate for inspection or visually inspecting the back surface of the front substrate box.
In other words, the front substrate box rotated downward about the lower hinge shaft is supported by its own weight by the stopper piece so as to be stationary.
In other words, it is necessary to provide a stopper member such as a stopper piece in order to stop the substrate box at a desired stationary position.
When there is no stopper member, the board box is excessively rotated by its own weight, and another member or device located below (for example, a ball guiding member protruding from the back of the game board or a rear protruding portion of the accessory device) This is because they may collide with each other and damage each other (see FIG. 6 of Patent Document 1).
In the invention disclosed in Patent Document 1, a stopper piece (stopper member) is provided in the vicinity of the lower hinge portion of the front substrate box, so that the stopper member is compact and assembled in a limited small space. be able to.
However, since the stopper member is limited to a shape and size that do not hinder the hinge mechanism, the structure becomes complicated or it is difficult to provide sufficient strength.
For example, the maintenance / inspection work described above, in particular, the work of inserting or removing the terminal connector of the connection line with respect to various board connectors arranged on the circuit board of the board board in the back, or the board board box in the back In the operation of cutting off the sealed portion for inspection, the front substrate box opened to the stationary position with the back side facing upward is an obstacle.
For this reason, in order to perform the above-described work as easily as possible, an operator may put an arm on the front board box or press a part of the body. In such a case, a large external force may be applied to the base stopper member by using the front substrate box as a “lever”, which may damage the stopper member.
Therefore, it is conceivable to arrange the stopper member at a position corresponding to the free end of the front substrate box far from the vicinity of the hinge portion and to have a shape and size that can withstand external force. In this case, it is necessary to secure a space for disposing the stopper member directly below the front substrate box, and the space cannot be secured and may not be adopted.
As described above, when performing maintenance / inspection work on the back substrate box with the front substrate box stopped at the stationary position by the stopper member, the operator's arm or the like hits the front substrate box. There was a problem that workability was poor because it had to be done with care so that nothing happened.
Also, when removing the back board box from the box mounting part when visually inspecting the back side of the back board box, remove multiple screws from the boss part on the back side of the box mounting part. The substrate box must be removed, and a lot of labor is required for the work.
Also, it takes a lot of work to attach the removed back board box to the back of the box mounting part (ball contact) with a plurality of screws, and the back side of the back board box is visually inspected. It was awkward.
Therefore, in the invention disclosed in Patent Document 1, maintenance and inspection work for the front and rear substrate boxes is troublesome.

  In view of the above problems, an object of the present invention is to provide a gaming machine that can easily perform maintenance / inspection of the front and rear board boxes in a gaming machine in which the board box is superposed on the front and rear of the box mounting portion.

Here, in the front and back board boxes arranged in a state of being superimposed on the box mounting part, the board box arranged close to the box mounting part corresponds to the back board box during maintenance / inspection of the board box. The board box close to the worker corresponds to the board box in front.

Therefore, the horizontal rotation of the front substrate box is caused by the frictional force and the own weight generated in the hinge portion by a very simple structure in which the front substrate box is mounted on the rear substrate box so as to be horizontally rotatable by a hinge mechanism. It can be stopped at the position.
In other words, unlike the conventional one in which the front substrate box is rotated downward and stopped by the stopper piece, the front substrate box is stopped in a state where it is rotated to a desired horizontal angular position without providing the stopper piece. .
Further, in a state where the front substrate box is rotated to a desired horizontal angle position, the back surface (front surface) of the front substrate box is in a horizontal direction, and external force from above does not act almost.
As a result, the front substrate box is rotated to a desired horizontal angular position, and the back surface (front surface) of the front substrate box and the front surface (rear surface) of the back substrate box are respectively exposed to expose the front and rear substrates. Maintenance and inspection of the box can be performed easily.
It is also possible to arbitrarily change the stationary position of the front substrate box according to the work situation.
Therefore, for example, with respect to various board connectors arranged on the circuit board of the back board box, the operation of inserting or removing the terminal connector of the connecting line, or the sealing part arranged in the back board box The work of cutting for inspection can be easily performed without being obstructed by the front substrate box.
Furthermore, it is possible to easily perform an operation of visually inspecting the back surface of the front substrate box in a state where the front substrate box is rotated to a desired horizontal angle position.

Is a summary.

Accordingly, maintenance and inspection of the front and rear substrate boxes can be easily performed in a state where the front and rear substrate boxes are independently rotated by separate hinge mechanisms with respect to the box mounting portion.
For example, if both the front and rear board boxes are board boxes containing control boards (main control board, sub control board, etc.) that are subject to fraudulent actions, there are illegal circuit components in both board boxes. It is important to maintain and check whether or not During this maintenance / inspection, both the front and back substrate boxes can be easily visually inspected with the front and rear substrate boxes being independently rotated by separate hinge mechanisms.
In particular, when visually inspecting the back side of the back substrate box, without removing the back substrate box with respect to the box mounting part, by rotating the back substrate box in a state connected by a hinge mechanism, The back surface of the back substrate box can be easily inspected visually.
That is, in the above-mentioned conventional one, when visually inspecting the back side of the back substrate box, each time the box mounting portion must be removed by removing the plurality of screws from the box mounting portion, A lot of labor is required for the work. Furthermore, a lot of labor is required in the work of tightening the removed substrate box with a plurality of screws and attaching it to the original state.
On the other hand, according to the invention of claim 2, it is possible to save the trouble of attaching / detaching the back substrate box to the box mounting portion with a plurality of screws, and accordingly, the back surface of the back substrate box is visually observed.
