DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the pachinko ball launching device of this embodiment has drive rollers 1 and 2 disposed on both sides of the launch position inside the pachinko machine, and launch positions where these drive rollers 1 and 2 are disposed. From the firing direction (diagonally upward to the left in Fig. 1)
In order to guide the pachinko ball P flowing out from the launch rail 3 extending to the top and the outlet 4 of the pachinko ball P from the upper plate of the pachinko machine to the launch position, the pachinko ball P is arranged from the launch position to below the outlet 4. An introduction rail 5 and a ball feeding gear (ball feeding means) 6 arranged on the upper surface side of the introduction rail 5 are provided.

Here, the introduction rail 5 is composed of a fixed portion 5a on the firing position side and a swinging portion 5b on the outflow port 4 side. The swinging portion 5b swings downward on the firing position side so that the pachinko balls P can be dropped without being supplied to the firing position.
At the end on the outflow port 4 side, it is pivotally attached to the body of the pachinko machine by a horizontal shaft, and is swingably driven by an actuator such as a solenoid (not shown). Below the swinging portion 5b of the introduction rail 5, the swinging portion 5b is
A guide wall 7 is provided for introducing a pachinko ball P, which falls when b swings downward, into a spare dish of a pachinko machine.

The ball feed gears 6 are arranged with their outer circumferences facing the upper surface of the introduction rail 5 at intervals such that the pachinko balls P pass through one by one, and are pivotally attached to the machine body of the pachinko machine by a horizontal axis orthogonal to the paper surface in FIG. A plurality of grooves 6a into which pachinko balls P are inserted are formed on the outer circumference at a predetermined pitch on the entire circumference, and are driven by a motor (not shown) or the like to rotate at a predetermined speed to flow out from the outlet 4. It has a function of feeding the pachinko balls P one by one to the firing position at a predetermined speed (for example, 100 / minute).

The drive rollers 1 and 2 are arranged parallel to each other on both sides of the firing position at intervals smaller than the outer diameter of the pachinko balls P, and also by the horizontal axis perpendicular to the plane of FIG. It is pivotally attached to the motor and is driven by the same motor (not shown) to rotate synchronously. Outer peripheral portions 1a of the drive rollers 1 and 2,
2a, when the pachinko balls P are sandwiched by the drive rollers 1 and 2 and fed to the launch rail 3 side, the pachinko balls P are released by the restoring force after the outer peripheral portions 1a and 2a are elastically deformed. It is formed of a synthetic resin or the like having appropriate characteristics (elasticity, friction coefficient, etc.) so as to be fired along.

The drive rollers 1 and 2 are delicately moved in the directions of approaching and separating from each other by, for example, an actuator (not shown), so that a ball firing handle (not shown) operated by the player can be operated. Accordingly, the interval or the number of revolutions of the pachinko balls P changes so that the firing speed of the pachinko balls P changes.

The launch rail 3 is connected to a so-called guide rail on the board surface of the pachinko machine, and a drop port 3a for dropping a pachinko ball P returned to the auxiliary plate without being driven into the board surface near the launch position. Are formed. The shape and size of the drop port 3a and the formation position are set so that the pachinko balls P shot at a normal speed do not drop into the drop port 3a immediately after the shot.

Next, the operation will be described. In the pachinko ball launching device, the pachinko ball P can be launched when the swinging portion 5b of the introduction rail 5 is in the normal position shown by the solid line in FIG. That is, the pachinko balls P flowing out from the outflow port 4 in this state are guided by the introduction rail 5 and are supplied to the firing position one by one by the ball feed gear 6. Then, when the pachinko balls P are sandwiched by the driving rollers 1 and 2 and fed out, the pachinko balls P are ejected along the ejection rail 3 by the restoring force after the outer peripheral portions 1a and 2a of the driving rollers 1 and 2 are elastically deformed. Is fired in the direction. Moreover, the firing speed at this time is the characteristics of the material (elasticity, coefficient of friction, etc.) of the outer peripheral portions 1a, 2a of the drive rollers 1, 2, the spacing between the drive rollers 1, 2, the rotational speed of the drive rollers 1, 2, etc. The player can adjust and maintain this firing speed to a constant value by the operation amount of the ball firing handle described above, and if the operation amount of the ball firing handle is maintained, there is almost no variation. .

If the fired pachinko ball P returns without reaching the inside of the board due to a shortage of the firing speed or the like, the pachinko ball P drops from the drop port 3a onto the spare plate, so The firing of the pachinko ball P is not hindered. Further, if the swinging portion 5b of the introduction rail 5 is swung downward, the pachinko balls P flowing out from the outlet 4 will fall onto the spare plate before reaching the position of the ball feeding gear 6, so at the time of so-called stopping. It is possible to limit the firing of the pachinko balls P.

Therefore, according to the above-mentioned launching device, the launching speed of the pachinko balls can be stably maintained, so that the pachinko balls can be hit at the position aimed by the player according to the ability of the player, which makes the game enjoyable. It has the effect of improving the thrill and the like. Further, since the pachinko balls are fired by rotating the driving rollers 1 and 2 in one direction, the pachinko balls need to be pulled back every time one pachinko ball is hit, as compared to a conventional shooting device. The performance to continuously launch at high speed is significantly improved.

[0018]

According to the pachinko ball launching device of the present invention, the firing speed of the pachinko ball can be stably maintained, so that the pachinko ball is driven into a position aimed by the player according to the ability of the player. As a result, the enjoyment of games and thrills are improved, which in turn can contribute to an increase in demand for pachinko machines.

Further, when the introducing rail is provided with a swinging portion which swings so as to open downward, the pachinko balls supplied to the introducing rail are swung to swing down the swinging portion, and the spare tray is provided below. Since it is possible to drop the ball, it is possible to disable the firing of the ball when it is stopped, which is convenient.
