Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to pinball game machines, such as pachinko machines, coin-operated machines, and arrangement-type pachinko machines. The present invention relates to a pinball game machine equipped with a game device.

[Prior Art] This type of pinball game machine has been generally known for some time, for example,
As described in Japanese Patent Publication No. 43766, a game board is equipped with a tulip, which is an example of an electric game device that is driven to open and close by a solenoid, and as described in Japanese Patent Application Laid-Open No. 57-43767, There was one in which a game board was equipped with a variable display device, which was an example of an electric game device that was driven and controlled by a motor or the like.

Conventionally, a game board equipped with the electric game device is detachably attached to the front frame of a pinball game machine, and when replacing a pinball game machine installed in a game parlor with a new game machine, In addition, only the game board equipped with the electric game device is removed and replaced with a game board equipped with a new electric game device. By configuring it in this way, the number of parts to be replaced is reduced, and the cost required for replacement is reduced.

On the other hand, in the so-called separate type pinball game machine in which the game board mentioned above is detachably attached to the front frame, a circuit board for controlling the electrical game device provided on the game board is housed. A circuit board storage member is attached to the mechanism board side, and the circuit board and the electrical gaming device are connected by electrical wiring or the like, and the electrical gaming device is configured to be electrically controlled by the circuit board. It had been.

[Problems to be solved by the invention] However, as mentioned above, when replacing a game board at a game parlor, the manufacturer will ask you about the game board equipped with the electric game device and the model of the electric game device. The board storage member containing the circuit board that meets the requirements is sent separately, and at the game parlor, the game board that is sent is attached to the front frame side, and the board storage member is attached to the mechanism board side. It is necessary to connect these electrical game devices and the circuit board by electrical wiring, and wiring connection errors may occur during the wiring work, resulting in frequent failures due to incorrect wiring. In addition, it may be necessary to open the mechanism board due to ball jams or malfunctions during operation at the game parlor, and in that case, the circuit board attached to the mechanism board side and the circuit board attached to the front frame side may Since the electrical game device is connected by wiring, not only is it necessary to remove the wiring before opening the mechanism board, which is a cumbersome task, but also prevents ball jams and malfunctions. After the mechanism plate is closed, the disconnected wiring must be reconnected, and there is a drawback that incorrect wiring occurs during the connection work.

In other words, in conventional separate type pinball game machines, the board storage member that houses the circuit board that is connected by electrical wiring to the electrical game device provided on the game board was installed on the mechanism board side. ,
Various inconveniences occur with the wiring connection work. Therefore, from the viewpoint of preventing mistakes in the wiring work, it is desired to mount the board storage member in a more rational location. If the board storage member is blindly installed in a location other than the above, a problem arises in that it is difficult to secure a mounting space for the board storage member in relation to other peripheral members.

In view of the above circumstances, the present invention has been developed by installing a board storage member in a more rational location from the viewpoint of preventing mistakes in wiring work between electrical game devices and circuit boards in a game hall. It is an object of the present invention to provide a pinball game machine that avoids mistakes in the wiring work as much as possible, and solves the problem of mounting space when mounting a board storage member to the mounting location.

[Means for Solving the Problems] A pinball game machine according to the present invention includes: a front frame, a game board detachably attached to the front frame side, and an electric game device provided on the game board. a board storage member disposed on the back side of the game board and housing a circuit board connected to the electrical game device by electrical wiring to control the electrical game device; The mechanism board is equipped with a prize ball payout mechanism that pays out a predetermined number of prize balls based on the winning balls that have entered the winning area of the game board, and the mechanical board is equipped with a prize ball payout mechanism that pays out a predetermined number of prize balls based on the winning balls that have entered the winning area of the game board. It is characterized in that the opposing portion has an avoidance structure that avoids the substrate storage member.

[Function] According to the present invention, the board storage member that stores the circuit board connected by electrical wiring to the electrical game device provided on the game board is connected to the electrical game device provided on the game board. Because it is attached to the back side, manufacturers can ship the game board with the electrical wiring between the electrical game device and the circuit board installed on the same game board. Therefore, when replacing a game board at a game hall, a game board with an electrical game device and a circuit board already connected by wiring can be received, and complicated wiring work at the game hall can be avoided as much as possible. moreover,
Because the circuit board storage member is attached to the back side of the game board rather than the mechanism board side, when opening the mechanism board, the electrical wiring that has been routed from the mechanism board side to the game board side must be removed. Work can be avoided as much as possible, and the occurrence of incorrect wiring when reconnecting disconnected electrical wiring can be prevented as much as possible. Furthermore, since the mechanism plate is configured to have an avoidance structure that avoids the board storage member, a mounting space for mounting the board storage member on the mechanism plate is secured. On the other hand, when a prize ball is paid out from the prize ball payout mechanism provided on the mechanism board, the prize ball collides with other members to generate static electricity, which charges the mechanism board. However, since the circuit board, which is relatively weak against static electricity, is housed in the board storage member and mounted on the game board, the adverse effects of the static electricity charged on the mechanism board do not directly affect the circuit board.

[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,
Although a pachinko game machine will be explained as an example of a pinball game machine, this invention can be applied to other pinball game machines,

And a lower ball tray 14b is provided. A mounting frame 15 is fixed to the back surface of the front frame 12.
A game board 16 is removably attached to the mounting frame 15. More specifically, the mounting frame 15 is formed into a frame shape with an inner diameter approximately equal to the outer diameter of the game board 16, and a portion of the mounting frame 15 is fitted with the peripheral portion of the game board 16. Further, the back surface portion of the game board 16 is held by a mounting bracket 15a provided on the mounting frame 15. The mounting bracket 15a is rotatable, and by its rotation, the game board 16 can be held in a state and the game board 16 can be removed from the mounting frame 15.

A mechanism plate 20 is rotatably mounted on the back surface of the mounting frame 15. The mechanism plate 20 is made of a synthetic resin material such as plastic. More specifically, in the mechanism board 20, a winning ball collection path 22 is formed on the front surface of the plate-shaped portion 21 (ie, the surface facing the back surface of the game board 16). A prize ball storage tank 23 is integrally provided at the upper part of the back surface of the plate-shaped part 21. Below the prize ball storage tank 23,
A path 25 is formed to line up the prize balls and guide them to the prize ball release mechanism 24. Prize ball release mechanism 2
A prize ball discharging gutter 25 is formed below the prize ball discharging mechanism 24 to guide the prize balls discharged from the prize ball discharging mechanism 24 to the upper ball receiving tray 14a and the lower ball receiving tray 14b. A mounting member 31 included in a mounting structure 30 for a board box 35, which is an example of a board storage member, will be described later, in a portion of the plate-shaped portion 21 excluding the prize ball release gutter 25.
Also, an opening 26 for exposing the substrate box 35 is formed. In addition, 99 in the figure is an electric game device such as a variable prize winning ball device. The size of the opening 26 is selected to be larger than the planar shape of the mounting member 31. A mounting member 31 is mounted on the surface of the game board 16 facing the opening 26, and a board box 35 is removably mounted on the mounting member 31.

3A to 3C show a mounting member 3 for explaining the mounting structure of a board box that houses a circuit board for controlling the electrical game device 99.
1 and a substrate box 35. FIG. The circuit board may also control a jackpot display lamp provided on the front frame.

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.
is formed. The mounting piece 314 has a mounting hole 31
5 is drilled. An engaging portion 32 is formed on the lower side of the front surface of the support base 311 when viewed from FIG. 3A. The engaging portion 32 is formed into an L-shape when viewed from the side, with one side facing upward.
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 housed 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.

When the mechanism plate 20 is closed so as to face the game board 16, the mounting member 31 and the board box 35
passes through the opening 26 of the plate-shaped portion 21 and is exposed to the back surface of the game board. In this manner, since the opening 26 is formed, the substrate box 35 will not collide with the plate-shaped portion 21 of the mechanism plate 20 when the mechanism plate 20 is closed. In this way, the mechanism plate 20 has an avoidance structure in which the portion facing the substrate storage member avoids the substrate storage member.

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 directly attached 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 protruding from the back surface of the holder 6 is selected to be slightly longer than that of the member 16a. 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. One side of a threaded bolt 45 is fixed to one of the longitudinal sides of the metal plate 411 (the left side in the figure). The other side of screw number 45 is L-shaped mounting bracket 4
It is fixed to 2. 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] The present invention can avoid as much as possible the occurrence of incorrect wiring between the electrical game device and the circuit board that occurs when replacing the game board or opening/closing the mechanism board at the game parlor. The accompanying failures can be minimized, and the problem of mounting space for the board storage member on the game board can also be solved.
