DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a ball winning device which catches a game ball by opening and closing a cover plate on a game board of a pachinko machine.

[0002]

2. Description of the Related Art A special winning opening provided for awarding a game ball to a game board of a pachinko machine is configured to open a horizontally long plate-like cover plate by operating a solenoid at a so-called big hit. Things.

[0003]

By the way, in the above-mentioned conventional winning opening structure, the cover plate is opened by inserting a wire or the like into the glass frame and forcibly opening the cover plate. There has been a case where a fraudulent act of illegally winning a game ball to obtain a prize ball is performed.

[0004] The present invention provides a ball winning device for a pachinko machine capable of overcoming such disadvantages, and aims to prevent improper activities.

[0005]

For this purpose, the present invention provides a game ball by supporting a cover plate on a rotating shaft provided substantially horizontally so as to be capable of standing up and tilting and tilting the cover plate by actuation of a solenoid. In a ball winning device of a pachinko machine that is captured on a cover plate and wins, a lock piece is formed such that a hook portion engages with an engaging portion formed inside the cover plate by its own weight when the cover plate stands up. And a brake release piece that is swingably suspended and provided with a lock release part that rocks the lock piece to release the engagement between the hook and the engagement part on the brake piece that moves forward and backward by the solenoid. I do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pachinko machine in which a game ball winning device 1 according to the present invention is provided on a game board 2, FIG. 2 is an external perspective view of the game ball winning device 1, FIG. 5 is an exploded perspective view of the mounting plate 3 and the main body 4, FIG. 5 is an exploded perspective view of the main body 4, FIG. 6 is a perspective view of a main part, and FIG. The mounting plate 3 is provided with a horizontally long winning opening 5, and ordinary winning openings 6 and 6 are provided on both sides thereof.

[0007] A rectangular cover plate 7 that matches the special winning opening 5 is supported on the main body 4 by rotating shafts 7a, 7a so as to be able to stand up and tilt freely. Reference numerals 7b and 7b denote this bearing member.
Reference numerals 8 and 8 denote flanges integrally formed on the rear surfaces of both side edges of the cover plate 7, and reference numeral 9 denotes an engagement portion projecting horizontally from an outer surface of one of the flanges.

Reference numeral 10 denotes a solenoid provided vertically on the main body 4, reference numeral 11 denotes a braking piece fixed to the tip of a spindle of the solenoid, and reference numeral 12 denotes a return coil spring for urging the braking piece downward. A pair of protrusions 1 is provided on the front edge of the braking piece 11.
3 and 14 are formed in a substantially U-shape, and the engaging portion 9 faces between the protrusions 13 and 14.

Reference numeral 15 denotes a lock piece suspended from the main body 4 by a pivot 16 so as to be swingable. A hook portion 17 is formed on one side surface of the lock piece, and when the cover plate 7 stands up, the engaging portion 9 engages with the hook portion 17 as shown in FIG. Locked to state. Also,
Reference numeral 18 denotes an unlocking portion in the form of an upright bar formed on the braking piece 11, and reference numeral 19 denotes an oblique streak-like cam portion formed on the back surface of the locking piece 15 so as to face the unlocking portion. The solenoid 10 is excited. When the lock release unit 18 moves upward, FIG.
0, as shown in FIG. 12, the tip of the lock release portion 18 comes into contact with the cam portion 19 to swing the lock piece 15 as shown by the arrow to release the engagement between the hook portion 17 and the engagement portion 9. .

Reference numeral 20 denotes a vertically long oval-shaped through hole formed in the mounting plate 3. A rod-like pin 20 is inserted into the through hole 20 as shown in FIG. 11, and the pin is moved up and down. The lock piece 15 is swung as indicated by a broken line in FIG.
The locked state with the engaging portion 9 can be released. For this reason, the through hole 20 can be used when it is necessary to open the glass frame and open the cover plate 7 as a legitimate act by a store clerk or the like at the game arcade.

In the ball winning device constructed as described above, as shown in FIGS. 6, 9 and 11, when the solenoid 10 is demagnetized and the braking piece 11 is lowered by the elasticity of the coil spring 12, the pivot 16 Of the lock piece 15 suspended by its own weight, the hook portion 17 engages with the engagement portion 9 and the cover plate 7 is in the locked state in the upright state. The plate 7 cannot be opened even if it is forcibly opened.

Further, the solenoid 10 is excited, and FIG.
When the brake piece 11 moves upward as shown in FIGS. 10 and 12, the lock release portion 18 hits the cam portion 19 and swings the lock piece 15 to release the engagement between the hook portion 17 and the engagement portion 9. At the same time, the lower protruding portion 14 raises the engaging portion 9 so that the cover plate 7 is inclined forward. When the cover plate 7 is tilted forward, the center of gravity of the cover plate 7 is located outside the rotation shafts 7a, 7a, so that the cover plate protrudes by its own weight to a greater extent into the game ball flow-down space of the game board to capture game balls. You will get. When the solenoid 10 is demagnetized, the coil spring 12
As the braking piece 11 moves down due to the elasticity of the engaging member 9, the engaging portion 9 is pushed down by the upper protrusion 13 and returns to the upright state.

Further, in the configuration shown in this embodiment, the locked state is not released unless the pin 20 is inserted into the through hole 20 and moved up and down as described above, so that an unauthorized player pushes the wire into the through hole 20. However, the locked state cannot be easily released even if there is anything.

[0014]

As described above, according to the present invention, the cover plate is supported on the rotating shaft provided substantially horizontally so as to be able to stand upright and tiltable, and the game ball is placed on the cover plate by tilting the cover plate by the operation of the solenoid. In the ball winning device of a pachinko machine that is captured and wins, the lock piece is swung so that the hook portion engages with the engaging portion formed inside the lid plate by its own weight when the lid plate stands up. In addition to being freely suspended and provided with a lock releasing part for releasing the engagement between the hook part and the engaging part by swinging the lock piece on the braking piece which is moved forward and backward by the solenoid, the lid plate can be securely secured. It can be kept closed and has a beneficial effect of preventing fraud.
