Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a hay-shaped mechanism frame that houses a game board is fixed to a door frame, and a horizontally long fixing plate with a longitudinal section crank-shaped is provided at the lower part of the inside of the mechanism frame. A game board is removably supported on the top surface so as to be crimped to the mechanism frame, and the surface of the fixed plate is provided with an oblique firing band and a foul ball guide gutter with the slanted upper end of the firing band facing the upper end entrance. The present invention relates to a pachinko machine in which a firing hole is inserted into a notch formed in the lower surface of a fixed plate.

Conventionally, the door frame of a pachinko machine was hinged to the green side of the rock frame that made up the exterior so that it could be opened and closed freely, and the game board was integrally attached to the back of this door frame via a mounting bar. In order to make it easier to change the appearance of the Pachinko machine, so-called detachable Pachinko machines have been provided in which the game board is not fixedly attached to the door frame but is detachably attached.

Generally, this type of pachinko machine has a sparrow-shaped mechanism frame fixedly attached to the back of the door frame hinged to the machine frame, and a game board is detachably housed inside this mechanism frame.
If necessary, the stopper can be removed and only the game board can be removed.However, in conventional pachinko machines of this type, the mechanism frame formed in a shaded shape is exposed from behind the door frame. The game board was simply removably mounted inside the mechanism frame. For this reason, there is a large gap between the lower part of the game board and the door frame, and within this closed area, a firing village, a firing band, and a ball guide gutter are provided. However, even if a firing band or a fur ball guide gutter is provided, the opening □ will not be closed. Therefore, if a problem occurs and the front panel is opened, the connection between the prize ball discharge gutter and the ball supply tray will be severed, and the balls that will be broken will fall from the above-mentioned closing part into the inside of the pachinko machine row and be recovered. This may cause inconveniences such as the wire getting lost, or a wire or the like entering the closed portion to commit fraudulent acts. The present invention has been made in view of the above, and a mechanism frame formed in a cliff shape is arranged on the back side of the window of the door frame, and the internal lower part of the mechanism frame has a vertical cross section consisting of an upper surface part, a vertical slope part, and a lower surface part. A crank-shaped fixed plate is provided to close the gap with the door frame, and a game board is removably mounted on the upper surface of this fixed plate.
By attaching a firing band and a ball guide trough to the vertical surface, forming a notch in a part of the lower surface, and inserting the firing village into the notch, it is possible to prevent balls from breaking when the front panel is opened. This pachinko machine is designed to prevent metal wires from falling into the inside of the machine, and to prevent metal mesh wires, etc. used for illegal gaming, inserted between the opening of the mechanism frame and the glass metal frame, from entering. It is about providing.

Below, the present invention will be explained with reference to the illustrated embodiments, and other features will be explained. Reference numeral 1 is a machine frame formed by framing wooden boards into a rectangular shape. Reference numeral 2 is a hinge (not shown) at the opening and side edges of this rock frame. 3 is a mechanism frame housed in a window 4 opened in the door frame, 5 is a game board housed inside this mechanism frame, and 6 is a mechanism frame mounted on the inner periphery of the window 4. It is a glass metal frame that houses glass plates 7, 7 which are attached so as to be openable and closable and which close the front of the game board.

The mechanism frame 3 is formed by press forming a metal plate into a raised shape.
It is formed into a rectangular shape with outward-facing mounting flanges 8 integrally provided at the tips of the four side walls 3'.

In order to fix this mechanism frame 3 to the door frame 2, for example, place it facing the window 4 from the front and insert it with iron, attach the mounting collar 8... to the front of the door frame 2, and then nail or fasten it from the front. Drive in screw 9... The fixed mechanism frame has a vertical section 10a, an upper section 1ob extending inward, and a lower section 10c extending outward, and the vertical section is bent into a crank shape. A fixing plate 10 made of a metal plate is installed in advance, and the fixing plate closes the gap with the back side of the door frame 2, and the game board 5 is placed in the upper space inside the mechanism frame partitioned by the upper surface part 10b of the fixing plate. It is designed to fit. A firing band 11 is obliquely provided on the surface of the vertical surface portion 10a of the fixing plate 10, and a Far ball guide gutter 12 with an inlet facing the inclined upper end of the firing band 1 is attached. Also, a lower surface portion 10 facing the inclined lower end of the firing band 11
A notch 10d is formed in a portion of c as shown in FIG. 1, and the firing ring 11' inserted into the notch 10d can be rotated along the vertical surface 10a within this notch 10d. At the same time, the upper end of the firing village 11' faces the inclined lower end of the firing band 1. Note that, as shown in FIG. 2, the upper surface portion 10b has a width from front to back that is approximately the same as the thickness of the game board 5 since the game board 5 is placed thereon. In the pachinko machine according to the present invention, the fixing plate 10 also closes the space between the mechanism frame 3 and the door frame 2 as described above, so even if the balls are broken when the front panel is opened, these balls cannot be fixed. Lower surface part 1 of plate 10
It can be received above 0c.

On the other hand, the game board 5 is formed to a size that fits in the above-mentioned space formed inside the mechanism frame, and on the front side thereof, along the surrounding green, there are guide rails 13, obstacle nails 14, and other winning ball receiving devices (not shown). Shielding walls 15 are provided on the upper green and the left and right green so as to surround the parts.

The shielding wall 15 in this embodiment is formed by bending a metal band plate into a crank-shaped cross section, with one piece 15a facing the end face of the game board, and one piece 15b of the intermediate piece facing the front side of the game board. Secure by nailing and attach the other piece 1
5c is made to rise at right angles from the front surface of the game board, and the rising piece 15c substantially surrounds the front surface of the game board.

The shielding wall 15, that is, the raised piece 15c is made higher than the guide rail 13 that guides the ball, the obstacle nail 14, etc., and is made to have a uniform height over the whole body.
The back side of the glass metal frame 6 that closes the front side of the game board 5 can be received. By the way, as shown in the figure, when the mechanism frame 3 houses the game board 5 therein, the mechanism frame 3 has a shielding wall 1 for the game board.
5 fits into the back of the window 4 opened in the door frame, and when the glass metal frame 6 is further closed in front of it, this glass metal frame 6 will fit into the window 4.
The game board 5 rests on the upper surface 10b of the fixed plate 10 and is placed on the left and right side walls of the mechanism frame 3. 3', 3' are supported in a crimping manner inside the mechanism frame 3 by the hooks of the cotton binding tools 16....

The tightening tool 16 is rotatably attached to a support shaft 18 extending between a pair of pieces 17, 17 formed by cutting and raising the side wall 3'.
By operating the knob 19 protruding outward from the side wall, the locking piece 20 protruding into the mechanism frame is actuated, and the locking piece 20 is caused to ride on the intermediate piece 15b of the shielding wall 15 attached to the edge of the game board. It is designed so that it can be fixed in a detachable manner. As described above, according to the present invention, the sparrow-shaped mechanism frame is placed on the back side of the door frame, and the mounting collar 8 is positioned by the mounting collar 8 to fix the mechanism frame 3 to the door frame 3. Therefore, the mechanism frame 3 is fixed to the door frame. It's extremely easy to do.

In addition, since the game board is supported by the mechanism frame in a crimped manner using the tightening device provided on the mechanism frame 3, the game board will not move slightly due to the vibration of the launcher or the impact caused by opening and closing the door frame, and will not be affected by temperature or humidity. Due to the change, the game board will warp and nails will not hit the glass plate and the ball will not fall. Furthermore, the game board can be attached to and removed from the mechanism frame from the front by opening the glass metal frame of the door frame, so it can be installed and removed extremely easily from the mechanism frame fixed to the door frame. This has a significant effect on work efficiency when replacing the game board of a pachinko machine. In addition, since a diagonal firing band and a guide gutter for the Fuar ball are provided on the surface of the fixed plate, with the slanted upper end of the firing band facing the upper end entrance, the delicate positioning of the firing band and the guiding gutter is disturbed. It never happens,
The fixed plate can be reinforced.

Therefore, it is extremely effective as a pachinko machine with a separate game board.
