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 movable rail part of an outer rail provided on the surface of a game board.

[0002]

2. Description of the Related Art Conventionally, a variable display device, a start winning opening and a special winning opening are provided on a game board as represented by a model called a seven machine, and a variable display device is provided when a hit ball is won at the starting winning opening. The change of the display state is started and stopped after a certain period of time, and a so-called big hit state is generated in which the special winning opening is converted into a state in which it is easy to accept a hit ball for a predetermined time or a predetermined number of times based on the stopped display state of the display device. It is known that a large number of prize balls are obtained in this way.

In the big hit state, for example, the opening / closing piece or the door of the special winning opening is opened and closed for a predetermined time, or until a predetermined number of hit balls are won, a continuous winning opening provided in the special winning opening is hit. When a prize is won, the cycle of the big hit state is updated, and when the hit ball does not enter the special winning opening, the big hit state is electrically controlled so as to end. Therefore, it is most convenient for the player to update the cycle after obtaining a winning ball close to the maximum allowed in the big hit state.

[0004]

However, in the current pachinko machine, there is no method other than adjusting the firing force of the hit ball in order to intensively hit the hit ball at the special winning opening. It is quite difficult for an amateur player.

[0005]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above problems and is located above the inner upper end of the inner rail of the outer rail, of the outer rail and the inner rail provided on the surface of the game board. A portion is a movable rail portion, and the movable rail portion is configured to be movable inward of the game portion by an electric drive means.

[0006]

[Operation] When the movable rail portion of the outer rail is moved inward of the game portion, the degree of curvature is increased and the momentum of the hit ball is killed, and the movable rail portion approaches the obstacle nail. It becomes easier to drop the ball at the place where it is aimed, and it is possible to concentrate the ball at the special winning opening.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko machine to which the present invention is applied. In the figure, 1 is a front frame of a pachinko machine, 2
Is a glass frame mounted on the front surface of the front frame 1 so as to be openable and closable.
Is a game board detachably attached to the rear surface of the front frame 1. An outer rail 4 and an inner rail 5 are provided on the surface of the game board 3, and a large number of obstacle nails 7, windmills 8 and a plurality of winning holes are provided in a game section 6 surrounded by the outer rail 4 and the inner rail 5. Big prize hole 11 integrated with the chucker 9 and the variable display device 10 and a plurality of starting prize holes 12 as specific prize holes.
Etc. are provided. Reference numeral 13 is a launch rail, and 14 is a lens-like decoration member disposed on both the left and right outer sides of the outer rail 4.

The special winning opening 11 is provided with a pair of openable and closable pieces 16, 16 on the front surface of a mounting board 15,
Normally, the opening / closing pieces 16, 16 are in a closed state so as not to receive a hit ball. Further, the start winning port 12 changes the display on the display unit of the variable display device 10 when a hit ball is won. Then, the opening / closing pieces 16, 1 of the special winning opening 11 are combined by the combination of the displays in the state where the fluctuation is stopped
6 is opened for a predetermined time or a predetermined number of times as shown by a chain line in FIG. 2 to generate a big hit state in which the hit ball is easy to win.

Although the outer rail 4 is usually fixed to the game board 3 by a specially constructed split pin or the like,
In the present invention, a portion of the outer rail 4 located above the inner upper end 5a of the inner rail 5 is formed as the movable rail portion 4a without being fixed to the game board 3. An electric drive means 17 is provided on the front surface of the game board 3 located near the end of the movable rail portion 4a. The movable rail portion 4
The outer rail 4 and the inner rail 5 other than a are fixed to the game board 3 by split pins 18 or the like as in the conventional case.

As shown in FIGS. 2 and 3, the drive means 17 has a solenoid 19 and a plunger 20, and the lower end of the plunger 20 is connected to the end of the movable rail portion 4a. The driving means 17 is placed inside the decoration member 14 so as not to be seen from the front.

On the other hand, a rail support member 21 is fixedly provided on the front surface of the game board 3 located outside the movable rail portion 4a. The rail support member 21 includes a movable rail portion 4a.
The side surface along the outer side of is formed as a rail receiving surface 21a, and normally, the movable rail portion 4a is added to the rail receiving surface 21a so that the curved shape is properly maintained. The rail support member 21 is formed in the same hollow shape as the decoration member 14, and the lamp 22 is provided therein. In the case of the present embodiment, for example, the solenoid 19 is set to be excited when a big hit state occurs and demagnetized when the big hit state ends.

Therefore, when the solenoid 19 is excited, the plunger 20 of the solenoid 19 is returned to the return spring 23 as shown by the chain line in FIG.
The movable rail portion 4a is pushed downward inward of the game portion 6 so as to be movable. Therefore, the movable rail portion 4a
The degree of curvature becomes large, and the momentum of the hit ball struck in the game section 6 is killed, so that it is possible to easily aim and hit. Further, since the movable rail portion 4a is brought close to the obstacle nail 7, the hit balls can be concentrated on the central portion or the right side portion of the game portion 6, so that a large number of hit balls can be won in the special winning opening 11 in a short time. it can.

On the other hand, when the solenoid 19 is demagnetized, the plunger 20 of the solenoid 19 is returned to the position shown by the solid line in FIG. 2 by the return spring 23, and the movable rail portion 4a is pulled up to be fitted to the rail receiving surface 21a of the rail supporting member 21.

FIGS. 4 and 5 show another embodiment of the drive means 17, which is fixedly provided on the front surface of the game board 3 for a forward / reverse rotation motor 24 and a movable rail portion 4a. Rack 25 screwed to the end of
A pinion 27 fixed to a motor shaft 26 of a motor 24 is meshed with the rack 25.

Therefore, the rotation of the motor 24 in one direction causes the rack 25 to move downward as shown by a chain line in FIG. 4, and pushes the movable rail portion 4a toward the inside of the game portion 6 to move it. Further, the rack 2 is rotated by the rotation of the motor 24 in the opposite direction.
5 returns to the position shown by the solid line in FIG.

[0016]

As described above, according to the present invention, a portion of the outer rail provided on the surface of the game board, which is located above the inner upper end of the inner rail, is the movable rail portion, and the movable rail portion is the game. Since it is configured to be movable inward of the portion and the degree of curvature thereof can be changed, it is possible to easily aim and hit the hitting ball and to concentrate the hitting ball on the central portion of the game portion.

Therefore, the player's interest can be attracted and the interest of the game can be remarkably enhanced. For example, when a big hit state occurs, a large number of hit balls can be concentrated on the special winning opening to effectively win the prize. There are beneficial effects such as.
