Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to pinball gaming machines such as pachinko gaming machines, coin gaming machines, arranged pachinko gaming machines, etc. This invention relates to a pinball game machine that is detachably attached to the frame side.

[Prior Art] This type of pinball game machine has been generally known for some time, for example,
There are those that are equipped with a solenoid for opening and closing an electric game machine called a chulip, which is equipped with a game board, such as the one described in Publication No. 43766, and the one described in Japanese Patent Application Laid-Open No. 57-43767. Some games were equipped with a motor to rotate a variable display device provided on the game board.

Conventionally, electrical components such as solenoids and motors were installed on the game board, and the game board was removably attached to the front frame of the pinball game machine and installed in the game hall. When replacing a pinball game machine with a new game machine, only the game board equipped with the electric Yakumono or variable display device is removed and replaced with a new electric Yakumono or game board equipped with the variable display device. It was configured like this. By configuring the device in this way, the number of replacement parts is reduced and the cost of replacement is reduced.

On the other hand, in a so-called separate type pinball game machine in which the game board described above is detachably attached to the front frame, electrical components are used to drive the electric Yakumono and variable display device provided on the game board. The circuit board that controls this is installed on the mechanism panel side.
The circuit board and the electrical component are connected by electrical wiring, and the electrical component is electrically controlled by the circuit board.

However, as mentioned above, when replacing a game board at a game parlor, the manufacturer sends the game board equipped with the electrical components and the circuit board for controlling the electrical components separately. At the game parlor, it is necessary to attach the received game board to the front frame side, attach the circuit board to the mechanism panel side, and connect these electrical parts and the circuit board with electrical wiring. However, wiring connection errors may occur during wiring work, and faults often occur due to incorrect wiring. In other words, in the past, since the electrical components and the circuit board were installed at different locations, it was necessary to connect the wiring between the two by passing the wiring through a predetermined wiring path after installing the electrical components and the circuit board at the respective installation locations. This causes the wiring connection error. In addition, it may be necessary to open the mechanism panel due to a ball jam or breakdown during operation at a game parlor, and in that case, the circuit board attached to the mechanism panel and the circuit board attached to the front frame side may Since the electrical components in the machine are connected by wiring, not only is it necessary to remove the wiring before opening the mechanism panel, which is a cumbersome task, but it is also necessary to remove the wires before opening the mechanism panel. After closing, the disconnected wiring must be reconnected, and there is a drawback that incorrect wiring may occur during the connection work.

[Problem to be solved by the invention] Therefore, a circuit board that is connected by electrical wiring to the electrical parts provided on the game board side is attached to the back side of the game board where the electrical parts are installed. With this configuration, the manufacturer can ship the game board with electrical wiring between the electrical parts and the circuit board included in the same game board, and When replacing a game board, it is possible to receive a game board with the electrical parts and circuit board already connected by wiring, thereby avoiding complicated wiring work at the game hall as much as possible.

On the other hand, in a pinball game machine installed in a game parlor, the circuit board may break down before the game board has yet to be replaced. In such a case, if the circuit board is attached to the back of the game board in a non-removable manner, replace only the faulty circuit board with a new one or remove only the faulty circuit board. This has the drawback that it cannot be repaired, and it is difficult to handle the circuit board when it breaks down.

The present invention was devised in view of the actual situation, and its purpose is to make it possible for manufacturers to install a circuit board on the back side of the game board, thereby facilitating the wiring work between electrical components and the circuit board. It is possible to ship to each game hall in a completed state, to prevent the occurrence of incorrect wiring due to wiring work between electrical parts and circuit boards at the game hall, and to prevent circuit boards from malfunctioning at the game hall. To provide a pinball game machine that can easily handle the cases where the game occurs.

[Means for Solving the Problems] The present invention is a pinball game machine in which a game board is removably attached to the front frame side, and the game board side is located approximately in the center of the game board. an electrical component provided in the game board; and a circuit board connected to the electrical component by electrical wiring to control the electrical component; It is characterized by being removably attached to the back side of the board.

[Function] According to the present invention, the circuit board that is connected by electrical wiring to the electrical components provided on the game board side is attached to the back side of the game board to which the electrical components are attached. Therefore, manufacturers can ship the same game board to each game arcade with electrical wiring between the electrical components and the circuit board installed on the same game board. When replacing a game board at a game hall, the game board can be delivered with the electrical parts and circuit board already connected by wiring, and complicated wiring work at the game hall can be avoided as much as possible. In other words, since the circuit board is mounted on the back side of the game board rather than on the mechanism board side, when opening the mechanism board, the electrical wiring that has been routed between the mechanism board side and the game board side must be removed. The work is avoided as much as possible, and the occurrence of incorrect wiring when reconnecting the disconnected electrical wiring can be prevented as much as possible. Furthermore, since the circuit board is configured to be removably attached to the back side of the game board, if the circuit board of a pinball game machine installed at a game parlor breaks down, the faulty circuit board will be damaged. The circuit board can be removed from the game board and the removed circuit board can be repaired or replaced with a new circuit board, making it easier to deal with breakdowns at the game parlor.

[Embodiments of the invention] Specific embodiments of the invention will be described below with reference to the drawings. In addition, in the explanation of the example,

Next, with reference to FIGS. 3A to 3C, the specific structure of the mounting structure for the substrate box of this embodiment will be described. The mounting member 31 includes a support base 311 . The support stand 311 is selected to have a horizontal length approximately equal to the horizontal length of the substrate box 35, and a vertical length which is longer than or approximately equal to the vertical length of the substrate box 35. The support stand 311 is formed into a box shape by bending a metal plate so that its thickness is relatively thin. An attachment piece 312 is formed on the upper side of the back surface of the support stand 311 (the surface facing the game board 16). The mounting piece 312 is provided with mounting holes 313 at appropriate locations. In addition, a mounting piece 314 is attached to the lower side of the back surface of the support stand 311.

The engaging portion 32 functions to position the lower side of the substrate box 35 and to support it from below when the substrate box 35, which will be described later, is attached to the support stand 311. In addition, a hole 316 is provided on the upper side of the support stand 311.
are drilled at predetermined intervals in the lateral direction.
On the back side of the support base 311 with holes 316,
A protrusion 317 having a screw hole is fixed thereto. A spring member 33a is screwed onto the protrusion 317. The spring member 33a is formed by bending an elastic wire-like member as shown in the figure, and a portion of the spring member 33a protrudes downward to elastically apply a pressing force to the surface of the support base 311. .

The board box 35 houses a circuit board for controlling the operation of the pachinko game machine 10, and is formed into a box shape. Note that the circuit board may be stored by attaching it to the game board 16 side and covering the rear side with a cover body. Third
Projecting pieces 351 are formed on the surface of the substrate box 35, which is the back surface when viewed from Figure A, to provide appropriate spacing. An engagement hole 352 is bored in the bottom surface of the board box 35 at a position corresponding to the engagement portion 32 . A clamp-shaped projecting piece 353 is fixed to the upper part of the back surface of the board box 35 when viewed from the side.

In the above-described configuration, first, the mounting member 31 is fixedly attached to the back surface of the game board 16 with screws or the like. Thereafter, the board box 35 is inserted into the engagement hole 352.
and the engaging portion 32 are positioned so as to engage with each other. The attachment member 31 may be a protruding member such as a winning ball collection cover body for guiding the winning balls to a predetermined location. Then, the tip of the spring member 33a is pushed upward, and the protruding piece 353 is moved to the support base 311.
The spring member 33a is then returned to its original position. As a result, the protruding piece 353 is pressed by the elastic force of the spring member 33n. This state is 3B
As shown in the figure. In this way, the board box 3
5 is detachably attached to the attachment member 31.

Note that when the mechanism plate 20 is closed so as to face the game board 16, the mounting member 31 and the board box 35 pass through the opening 26 of the plate-shaped portion 21 and are exposed to the back surface of the game board.

If configured as in this embodiment, the board box 35 will be located at a position that does not face the prize ball discharge gutter 25 through which prize balls flow, and will be removably attached to the back surface of the game board 16, so that pachinko balls will be awarded as prizes. The static electricity generated when the balls flow down through the ball discharge gutter 25 is not transmitted to the substrate box 35. Therefore, there is an advantage that the circuit board housed in the board box 35 can be effectively protected from high voltage discharge of static electricity. In addition, since the board box 35 is configured to be detachable from the mounting member 31, if the circuit board breaks down, the board box 35 can be replaced with another one, and the work efficiency at the time of replacement is good, so the game This has advantages such as eliminating the need to keep people waiting.

Note that the spring member is preferably connected to the board box 3.
It is preferable that the configuration is such that even if the lengths in the longitudinal direction of the parts 5 are different, they can be mounted on a common mounting member 31. For example, screw holes 318 and 319 are formed in the surface of the support base 311 at different positions in the vertical direction, so that it can be attached to any of the screw holes of the spring member 33b. In this way, as shown in FIG. 3C, the mounting position of the spring member 33b can be adjusted to the screw hole 318.
319, the board boxes 35 can be mounted using a common mounting member 31 even if the board boxes 35 have different lengths in the vertical direction.

Note that the board box 35 may be removably attached directly to the back surface of the game board 16 with screws or the like without providing the support stand 311.

FIGS. 4A and 4B are illustrative views of a mounting structure for arranging a board box on the back side of a protruding member 16a such as a winning ball collection cover body, and in particular,
FIG. 4A shows the mounting member 41 in a closed state, and FIG. 4B shows the mounting member in an open state. The mounting member 41 of this embodiment is made of a metal plate 411 whose horizontal length is approximately equal to the horizontal length of the board box 35 and whose vertical length is longer than the vertical length of the board box 35. , its upper end portion is bent into an L-shape when viewed from the side, and is provided with bent portions 412 and 413. Bending portion 412
The length in the direction perpendicular to the game board 16 is the length of the game board 1
The protruding length of the member 16a such as the winning ball collection cover body protruding from the back surface of the ball 6 is selected to be slightly longer. A spring member 44 having the same shape as the spring member 33b shown in FIG. 3A is attached to the game board 16 at a position corresponding to the bending portion 413. metal plate 4
One side of a hinge 45 is fixed to one of the longitudinal sides of the hinge 11 (the left side in the drawing). The other side of the hinge 45 is fixed to an L-shaped mounting bracket 42. Note that 43 is a spring member similar to 33b.

The structure for attaching the board box 35 to the metal plate 411 is the same as that shown in FIG. 3A, so its explanation will be omitted here.

With the configuration of this embodiment, even if there is a protruding member 16a on the back surface of the game board 16, the board box 35 can be detachably attached. In addition, the protruding member 1
6a has the advantage that it can be easily restored by rotating the support plate 411.

[Effects of the invention] According to the invention, it is possible to avoid as much as possible the occurrence of incorrect wiring between electrical components and circuit boards that occur when replacing game boards or opening mechanism panels at game parlors, and failures due to incorrect wiring can be avoided. can also be reduced as much as possible.

Moreover, if the circuit board of a pinball game machine installed in a game parlor breaks down, the faulty circuit board can be easily removed from the game board and repaired, or replaced with a new circuit board. This makes it easier to deal with circuit board failures at game parlors.
