Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having an improved mounting method of a board case containing a game control board.

[0002]

2. Description of the Related Art Generally, in a pachinko machine, a board case accommodating a game control board for controlling various electric components on the game board side is arranged on the back side of the game board. However, in recent years, the ratio of the rear of the center role to the back of the game board has increased due to the increase in the size of the center role, so that it has become impossible to secure a space for mounting the board case parallel to the game board. Was.

In order to solve this problem, there is a game machine in which the board case is set upright on one side of a game board using a vertically long space left on the side of the center role.

[0004]

However, recently, the size of the board case itself tends to increase due to the increase in the size of the board accompanying the multi-functionality of the game. However, there are disadvantages such as that the projections are large and the space in the vertical direction is insufficient and the space cannot be accommodated.

[0005] In order to solve this drawback, an empty space on the rear side of the lower back-part storage section that stores the back parts (for example, a winning ball detection device, a frame control board, etc.) on the lower rear side of the pachinko machine is used. In some cases, a large-sized board case is attached in parallel to the rear side of the lower back component storage section.

However, in this case, since the main part of the lower back-part storage section is covered by the board case, when the maintenance and inspection of, for example, the winning ball detection device and the frame control board in the lower back-part storage section are performed, the board case is removed. It is necessary to remove it from the lower back part storage part, and accordingly, it is necessary to disconnect the connector of the wiring that electrically connects the game control board. For this reason, every time maintenance and inspection are performed, it is necessary to perform a troublesome work of attaching and detaching the board case and the connector, and there is a disadvantage that maintenance of the back parts is deteriorated. Further, there is a possibility that erroneous connection of the electric wiring or forgetting of connection may occur.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and accordingly, it is an object of the present invention to make it possible to mount the board case on the rear surface side of the lower back component storage portion with a small protrusion to the rear of the board case. It is another object of the present invention to provide a pachinko machine capable of performing maintenance / inspection of a back part without attaching / detaching a substrate case.

[0008]

In order to achieve the above object, a pachinko machine according to claim 1 of the present invention comprises:
It is configured to be mounted on the rear surface side of the lower back component storage section via a hinge mechanism so as to be capable of opening and closing and rotating. In this configuration, normally, the rearward projection of the board case can be reduced by keeping the board case in a closed position parallel to the rear surface of the lower back component storage portion. Then, at the time of maintenance and inspection, if the board case is turned around the hinge mechanism as a fulcrum,
The rear side of the lower back part storage portion is opened, so that maintenance and inspection work of the back parts can be performed. In this case, it is not necessary to perform a troublesome work of attaching and detaching the board case and the wiring connector. Note that the lower back component storage portion may be provided integrally with the back component storage portion on the upper side thereof, or may be provided separately.

In this case, a hinge mechanism is provided on the upper side of the substrate case, and the substrate case is supported by the support member at a position where the substrate case is pivoted upward by a predetermined angle using the hinge mechanism as a fulcrum. Good. With this configuration, the substrate case can be easily held in a state of being opened upward. Also, for example, when the board case is opened in the horizontal direction, the worker needs to work around the open side of the board case and work in a cramped posture from the oblique side to the back parts. By opening upward, it becomes possible to work on the back parts from the front. Furthermore, since the upper side of the substrate case serves as a fulcrum of rotation, even if the substrate case is open, if the support by the support member is removed,
Due to its own weight, it will naturally return to the closed position. For this reason, the operation of returning the substrate case to the closed position after maintenance and inspection becomes extremely simple, and the means for holding the substrate case in the closed position may be simple (or this holding means may be omitted).

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. First, a schematic configuration of the back side of the pachinko machine 11 will be described with reference to FIGS. A prize ball tank 12 for storing pachinko balls is provided at an upper portion on the back side of the pachinko machine 11, and a tank rail 13 for flowing down the pachinko balls flowing out therefrom in an aligned state is connected to the prize ball tank 12. . A ball supply rail 14 is connected to a lower end of the tank rail 13, and a ball payout device 15 is connected to a lower end of the ball supply rail 14. A relatively large display device 16 such as a CRT and a liquid crystal display, which constitutes a center role, is attached to a game board (not shown) of the pachinko machine 11. It projects to the center on the back side. A lower back component storage unit 17 for storing back components is provided at a lower portion on the back side of the pachinko machine 11. Have been.

As shown in FIG. 5, a main back part, for example, a frame control board 19 for controlling the operation of various electric parts mainly on the back side of the pachinko machine 11, and a winning ball are stored in the lower back part storage unit 17. Openings for maintenance and inspection are formed at positions corresponding to the locations of the winning ball detection devices 20 to be detected. Normally, these openings are closed by opening / closing covers 21 and 22, and maintenance and inspection are performed.
At the time of inspection, the opening / closing covers 21 and 22 are opened so that maintenance and inspection of the frame control board 19 and the winning ball detection device 20 can be performed.

Next, the mounting structure of the board case 18 will be described with reference to FIGS. The board case 18
For example, a transparent resin base member 23 and a cover member 24
In the board case 18, a game control board (not shown) for mainly controlling the operation of various electric components on the game board side is accommodated.

In order to rotatably mount the substrate case 18 to the lower back component storage portion 17, hinge shafts 25 are integrally formed on both ends of the upper side of the base member 23 in a horizontal direction. , Upper part 2 of lower back part storage part 17
A hinge receiving member 26 is screwed at the location. Each hinge shaft 25 is received and supported by these hinge receiving members 26, and a detachable stopper 26 formed on the hinge receiving member 26 is formed.
As a result, the hinge shaft 25 is prevented from coming off upward by the resilient engagement shown in FIG. The hinge shaft 25 and the hinge receiving member 26 constitute a hinge mechanism.

Further, stopper portions 27 are provided at two places of the lower back component storage portion 17 in order to regulate the downward rotation position of the board case 18. Board case 18
Is rotated downward about the hinge shaft 25 as a fulcrum, and the substrate case 1 is rotated.
At the position where the base member 23 of FIG. 8 abuts on the stopper 27, as shown in FIG. 3A, the board case 18 is substantially parallel to the lower back part storage portion 17, and the opening / closing cover 21 for maintenance / inspection is provided. 22 (hereinafter, this position is referred to as a “closed position”).

In order to fasten the board case 18 to the lower back-part storage section 17 in the closed position, a fastening piece 28 is formed at the lower end of the board case 18 and corresponds to the fastening piece 28. A boss 29 is provided at the lower part of the lower back part storage 17.
Is provided. Insertion hole 2 formed in fastening piece 28
8a (see FIG. 4), a not-shown fastening member is inserted, and this fastening member is inserted into and engaged with the engaging hole 29a (see FIG. 5) of the boss portion 29, so that the board case 18 is mounted on the lower back part. Lightly fastened to the storage section 17.

When the board case 18 is rotated upward from the closed position with the hinge shaft 25 as a fulcrum, as shown in FIG. 3B, the board case 18 is moved from the maintenance / inspection open / close covers 21 and 22. It is in a state of being separated obliquely upward (hereinafter referred to as “open position”). In order to hold the board case 18 at the open position, a support member 30 formed by bending a steel wire into a substantially U-shape, for example, is rotatably attached to the central portion of the lower back component storage portion 17. This support member 30 is shown in FIG.
As shown in (2), by pivoting downward with the shaft portion 30a as a fulcrum and bridging the lower protruding portion 28a of the substrate case 18, the substrate case 18 is supported at a position pivoted upward by a predetermined angle. Further, a holder 31 (see FIG. 5) is provided in the lower back-part storage section 17, and when the support member 30 is not used, the support member 30 is rotated upward to hold the holder 3.
1, the support member 30 is held in a state of being stored in the lower back-part storage section 17 side.

On the other hand, the wiring led out from the game control board in the board case 18 is electrically connected to the electric circuit on the game board side and the frame control board 19 via a connector (not shown).

According to the mounting structure of the board case 18 configured as described above, the support member 30 is usually housed in the lower back-part storage section 17 side, and the board case 18 is parallel to the lower back-part storage section 17. In the closed position. Thus, even the large-sized board case 18 can be mounted in a state where the rearward projection of the board case 18 is suppressed to be almost as small as that of the display device 16 (center accessory) (see FIG. 2). . At this time, since the upper side of the substrate case 18 serves as a fulcrum of rotation, the substrate case 18 is naturally maintained at the closed position by its own weight. For this reason, it is not necessary to strongly fix the board case 18 in the closed position, and it is sufficient to lightly fasten the board case 18 to the lower back component storage portion 17 by the method of engaging with the fastening member as described above. is there. Also, if there is no problem, without using such fastening members,
The board case 18 may be configured so as not to be fixed to the lower back component storage section 17.

When the maintenance and inspection of the back parts are performed due to the occurrence of a trouble or the like, the substrate case 18 can easily be maintained and inspected by rotating the substrate case 18 upward and supporting it with the support member 30. Can be held at an open position which is separated obliquely upward from the opening / closing covers 21 and 22 for maintenance, and maintenance and inspection work of the back parts can be performed. For this reason,
When performing the maintenance and inspection, it is not necessary to perform the troublesome work of attaching and detaching the board case 18 and the connector of the electric wiring, and the maintainability of the back parts is improved. Furthermore,
Since there is no need to remove the board case 18, it is not necessary to secure a temporary storage place for the board case 18, and since there is no connector detachment, it is possible to prevent erroneous connection of electrical wiring and forgetting of connection.

Further, for example, when the board case 18 is opened in the horizontal direction, the operator needs to work around the open side of the board case 18 and work in a cramped posture from the oblique side to the back parts. However, if the board case 18 is opened upward as in the above embodiment, the operator can work on the back parts from the front, and the work becomes easier.

However, according to the present invention, the board case 18
The present invention is not limited to the configuration in which the substrate case 18 is opened upward, and a hinge mechanism may be provided on a side edge or a lower edge portion of the substrate case 18 so that the substrate case 18 is turned laterally or downward to open. The support member 30 may be appropriately changed according to the opening direction of the case 18. Alternatively, the support member 30 may be omitted. In addition, the support member 30 is connected to the board case 1
It may be attached to the 8 side.

In this embodiment, when it is necessary to remove the board case 18 from the lower back component storage section 17 such as when inspecting the board case 18 itself, the detachment stopper 26a of the hinge receiving member 26 is elastically attached. If the hinge shaft 25 is disengaged from the hinge receiving member 26, the board case 18 can be removed from the lower back component housing 17, and the board case 18 can be removed.
There is an advantage that the maintenance is easy. However, the present invention may be configured so that the hinge mechanism of the board case 18 does not come off.

Further, the lower back component storage section 17 may be provided integrally with the back component storage section on the upper side, or may be provided separately. In addition, it goes without saying that the present invention can be implemented with various changes without departing from the gist, for example, the shapes of the hinge shaft 25 and the hinge receiving member 26 and the shape of the support member 30 may be appropriately changed.

[0024]

As is apparent from the above description, according to the pachinko machine of the first aspect of the present invention, the board case is attached to the rear surface side of the lower back component storage portion via the hinge mechanism so as to be openable and closable. As a result, the board case can be attached to the rear side of the lower back part storage part with a small protrusion to the rear, and the back parts can be maintained and inspected without removing and attaching the board case. The maintainability of the back part can be improved.

In the second aspect, the hinge mechanism is provided on the upper side of the substrate case, and the substrate case is supported by the support member at the position where the substrate case is opened upward, so that the substrate case is opened upward. In this state, maintenance can be easily performed on the back part from the front, and maintenance performance can be improved. In addition, when the substrate case is not supported by the support member, the substrate case is naturally maintained at the closed position by its own weight, so that fastening at the closed position of the substrate case can be simplified or unnecessary.
