Field of the Invention The present invention relates to a pachinko gaming machine, and more particularly to a pachinko game machine, in which a hit ball supply tray and a surplus ball tray are provided on the front side of a front frame, and a game board is mounted on a back side of the front frame via a game board mounting frame. The present invention relates to a pachinko game machine which is detachably attached and has a gutter member for communicating the hitting ball supply tray with the surplus ball receiving tray.

[0002]

2. Description of the Related Art Conventionally, as is well known, a ball feeder and a surplus ball tray are provided on the front of a front frame of a pachinko game machine, and a game board is provided on the back of the front frame via a game board mounting frame. It is attached detachably. Also, on the back of the game board, a ball tank, a prize ball payout device, or a mechanism plate provided with a prize ball discharge passage, an excess ball passage, and the like are provided so as to be detachable and openable, and are paid out from the prize ball payout device. The obtained prize ball is guided to the hit ball supply tray by the prize ball discharge passage, and the prize ball overflowing from the hit ball supply tray is guided to the surplus ball tray via the surplus ball passage and the gutter member attached to the lower portion of the back of the front frame. It has been like that.

[0003]

By the way, in the above-mentioned conventional pachinko game machine, the gutter member for communicating the hitting ball supply tray and the surplus ball tray is simply screwed to the lower portion of the back of the front frame. When the player puts his hand on the back side of the front frame from the surplus ball outlet of the surplus ball tray and applies force, the gutter member is loosened and a gap is formed between the back surface of the front frame and the gutter member, or between the gutter member and the mechanism plate. Sometimes occurred. Then, a prize device mounted on the game board is opened by inserting a piano wire or a wire through the gap, or a game control circuit board (main board) mounted on the mechanism board and peripheral electronic components are operated to receive a prize. There has been a problem that illegal games such as obtaining a ball are easily performed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to surely prevent a fraudulent game played by inserting a piano wire, wire, or the like from a surplus ball outlet of a surplus ball tray. It is an object of the present invention to provide a pachinko gaming machine that can prevent such a situation.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a hit ball supply tray and a surplus ball tray on the front side of a front frame, and a game board mounting frame on a rear side of the front frame. In a pachinko game machine in which a game board is detachably attached via a gutter, and a gutter member that connects the hit ball supply tray and the surplus ball tray is attached, a part of the gutter member receives a lower end of the game board. A lower frame portion of the game board mounting frame, wherein the lower frame portion is attached so as to be sandwiched inside a back cover plate closing a rear opening of the lower frame portion.

[0006] The pachinko gaming machine thus configured is:
Even if the player puts his hand on the back side of the front frame from the surplus ball exit of the surplus ball tray and applies force to the gutter member, a part of the gutter member is firmly pressed by the back cover plate. So that there is no wobble,
It is possible to reliably prevent a fraudulent game played by inserting a piano wire, a wire, or the like from a gap between the back surface of the front frame and the gutter member, or a gap between the gutter member and the mechanism plate.

Outlet 53 and introduction opening 49 of inclined passage section 50 and mechanism plate 2
Nine surplus ball passages 38 are communicated with each other.

The pachinko gaming machine 1 constructed as described above.
The prize ball paid out from the prize ball payout device 36 is discharged to the prize ball discharge passage 37 and guided to the hit ball supply tray 8 from the prize ball outlet 22. When the hit ball supply tray 8 is filled with a prize ball, the surplus ball overflows from one side of the prize ball outlet 22 into the surplus ball passage 38, and the surplus ball overflows to the inclined passage portion 5 of the gutter member 25.
The surplus sphere is received by the surplus sphere outlet 53 and is guided to the surplus sphere tray 11. Further, a foul ball generated during the game or a ball removed from the hitting ball supply tray 8 is received by the ball receiving member 20 and guided to the funnel-shaped receiving port 46 of the gutter member 25 from the outlet hole 20a, and further the vertical passage. It flows down through the portion 47 and the inclined passage portion 50 and is guided to the surplus ball tray 11.

In the present invention, however, the vertical passage portion 47 of the gutter member 25 has a rear surface extending upward from the funnel-shaped receiving port 46 and can be sandwiched inside the back cover plate 40. The part 54 is formed integrally. The overlapping portion 54 is formed in a U-shaped gutter-like shape and has a lower frame portion 5.
a from the ball receiving member 20 facing the opening 44 of FIG.
6 serves as an auxiliary passage portion for reliably guiding the ball falling to 6 to the vertical passage portion 47. On the other hand, the back cover plate 40
A notch 55 is formed in the gutter member 25 so as to face the overlapped portion 54 of the gutter member 25. The upper edge portion of the notch 55 and the overlapped portion 5
The gutter member 25 is firmly pressed down by tightly contacting the upper end portion 4 so as not to shake.
Therefore, the surplus ball exit 53 of the surplus ball tray 11
Even if the user inserts his hand on the back side of the front frame 3 to apply force to the gutter member 25, the gutter member 25 is the lower frame portion 5a of the game board mounting frame 5 and the back cover plate 40 thereof. Since there is no wobbling between the gutter members and the gutter member 25 or the gap between the gutter member 25 and the mechanism plate 29, a piano wire, a wire, or the like is inserted through the gap between the gutter member 25 and the mechanism plate 29. It is possible to reliably prevent illegal playing.

[0014]

As is apparent from the above description, the present invention is provided with a hit ball supply tray and a surplus ball tray on the front side of the front frame, and a game board mounting frame on the rear side of the front frame. In a pachinko game machine in which a game board is removably mounted and a gutter member that connects the hit ball supply tray and the surplus ball tray is mounted, a part of the gutter member is mounted on the game board to receive a lower end of the game board. The gutter member is securely attached to the lower portion of the back of the front frame because the lower frame portion of the frame is attached to the lower frame portion while being sandwiched inside the back cover plate that covers the rear opening of the lower frame portion. It is possible to reliably prevent an illegal game played by inserting a piano wire or a wire through a gap between a back surface of a front frame and a gutter member or a gap between a gutter member and a mechanism plate as in a conventional pachinko game machine. it can.
