DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having a novel frame structure, and more particularly, to a game machine which can be easily exchanged and has excellent assembling accuracy.
The present invention relates to a pachinko machine capable of reducing the number of discarded members accompanying replacement.

[0002]

2. Description of the Related Art Usually, a pachinko machine in a pachinko hall or the like is installed side by side on one or both sides of a wall-shaped support structure called an island sandwiched between passages. As shown in FIG. 7, the conventional pachinko machine has a two-layer structure including an outer frame 1 attached to an island of a pachinko hall and an inner frame 2 attached to the outer frame 1 via a hinge mechanism so as to be openable and closable. It is configured as a structure. The inner frame 2 has a gauge board surface 3 on the surface side, and an upper plate 4a for storing pachinko balls, a lower plate 4b, an operation handle 4c, and the like are attached to a lower portion. Attachment of the inner frame 2 to the outer frame 1 is performed by matching the hinge brackets 2a of the inner frame 2 with the hinge brackets 1a of the outer frame 1 and aligning the pins and holes attached to those brackets with a key. The operation of the unit 4d moves the lock piece 4e up and down to lock the inner frame 2 with respect to the outer frame 1.

Recently, a large-sized display such as a liquid crystal is incorporated in a central portion of the gauge panel 3 so as to enhance a game property.

[0004] Further, a ball passage mechanism is provided on the inner side of the inner frame 2 of the conventional pachinko machine for controlling the passage of pachinko balls. That is, as shown in FIG. 8, a tray 5 for storing pachinko balls is provided at the uppermost portion of the inner frame 2, and the balls stored in the tray 5 are supplied into the prize ball payout unit 7 through the alignment passage 6. When a player wins a chucker or an attacker on the gauge board 3, a predetermined number of prize balls are paid out from the prize ball payout unit 7 to the upper plate 4a through the chute passage.

Further, in addition to the above-mentioned ball passage mechanism, a firing device 10 for firing a ball, and a substrate 12 for controlling a display (a display cover is indicated by reference numeral 11 in FIG. 8).
Are attached to the inner surface side of the inner frame 2.

[0006] As described above, the conventional pachinko machine is configured as a two-layer structure of the outer frame 1 attached to the island of the pachinko hall and the inner frame 2 having the gauge panel surface 3. On the front side, there is provided a gauge board surface 3 and a display which affect the game performance. On the inner side of the inner frame 2, a saucer 5, an alignment passage 6, a prize ball payout unit 7, a ball removing unit 8, a safe ball unit 9, and the like Various mechanical components that are not directly involved in the game performance, such as the ball passage mechanism and the launching device 10, are installed.

[0007]

By the way, a pachinko machine installed in a pachinko hall is called a new machine replacement with a pachinko machine having a novel game characteristic in order to gain an advantage over customer needs and competition with other stores. It is customary to change every two to three months, or in shorter cycles, and in recent years this cycle has tended to be shorter.

However, in a conventional pachinko machine having a two-layer structure of an outer frame 1 and an inner frame 2, when replacing a game machine, various heavy mechanical parts are incorporated and a new inner machine is required. Since the frame 2 is attached to the outer frame 1 via the hinge mechanism, inclination variations and the like are likely to occur on the gauge panel surface, and it is difficult to ensure good assembly accuracy, and the adjustment work is very troublesome. The problem has been pointed out.

When a new game machine is replaced, it is difficult to change only the game board 3 and the display or other parts that affect the game performance. If the inner frame 2 is replaced, the receiving tray 5 and the prize ball payout are required. Various mechanical components such as the ball passage mechanism such as the unit 7 and the firing device 10 and the key unit 4d also need to be changed, so that the effective use of the components cannot be achieved, the number of discarded members increases, and the disposal process is costly. There was also a problem in terms of environment.

Furthermore, in a structure in which various mechanisms such as a ball passage mechanism are installed on the inner surface side of the inner frame 2, a display and a substrate for controlling the display are installed because these mechanical parts are installed on the back side of the gauge cover. There is also a problem in that the installation space such as 12 is also restricted, and there are also restrictions on the workability of wiring cord mounting and the modeling of the gauge board 3.

[0011] The present invention has been made in view of such circumstances, and it is possible to increase the assembly accuracy when replacing a new game model and to facilitate the replacement operation.
It is an object of the present invention to provide a pachinko machine capable of obtaining a great cost advantage by reducing the number of discarded members and increasing the degree of freedom in forming the gauge panel surface and the degree of freedom in installing a display and a control device.

[0012]

Means for Solving the Problems In order to achieve the above object, an invention according to claim 1 is provided with an outer frame attached to the island side and an openable and closable attached to the outer frame via a hinge mechanism. The pachinko machine comprises at least an intermediate frame on which a ball passage mechanism is mounted, and an inner frame having a gauge panel surface on a front surface side and detachably attached to the intermediate frame.

For example, in the case of a pachinko hall, the outer frame is installed in parallel on each island. However, an island is not limited to a pachinko hall but is a general term for a support structure for mounting a pachinko machine. The intermediate frame is preferably formed of a reinforcing frame body such as a steel plate, and is attached to the outer frame so as to be openable and closable via a hinge mechanism.
As the ball passage mechanism provided on the inner surface side of the intermediate frame, preferably, a ball passage for pachinko balls supplied from a ball supply tank of each island, a prize ball payout unit (for a CR machine, CR
Sand lending unit), safe ball unit, out ball unit, etc. In addition, a control device for the ball passage mechanism is preferably mounted on the intermediate frame. This includes
Substrates such as a control device for paying out a prize ball every time the player wins a chucker or an attacker, and a control device for stopping supply of balls to the firing port when the lower plate is fully loaded are included.

Therefore, according to the first aspect of the present invention,
Since the intermediate frame has a frame function and the intermediate frame is attached to the outer frame via the hinge mechanism, there is no need to attach the inner frame to the hinge when replacing the game model. Only a new inner frame needs to be attached, good assembly accuracy can be obtained, and replacement work can be performed easily.

Further, in order to exchange for a new game model,
Since it is only necessary to replace the inner frame in which the gauge panel surface including the display unit is changed, the ball passage mechanism installed in the intermediate frame and the control device of the ball passage mechanism can be shared.

According to a second aspect of the present invention, the ball passage mechanism installed in the intermediate frame is extended toward the depth side along the hinge shaft side edge of the intermediate frame.

Therefore, according to the second aspect of the present invention,
The ball passage mechanism is centrally installed on the hinge shaft side edge of the intermediate frame, and furthermore, is installed so as to extend toward the depth side, so that a large space on the inner surface side of the inner frame can be secured,
It is possible to secure a large installation space for the display device, the display device substrate, and the like, which are installed on the gauge panel surface, and an installation work space for wiring cords and the like.

Further, the ball passage mechanism and its control device, etc.
Since the central frame can be installed at the hinge shaft side edge of the intermediate frame, the load applied to the hinge from the ball passage mechanism and its control device is small, and the opening operation of the intermediate frame can be performed smoothly.
