Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a rotating body provided with a plurality of vertical through-holes for accommodating a predetermined number of prize balls. This invention relates to a prize ball ejecting device for a pachinko machine that ejects prize balls.

[Prior Art] Conventionally, as this type of prize ball discharging device, those described in, for example, Japanese Patent Publication No. 55-40272 and Japanese Patent Application Laid-Open No. 60-227784 are known. All of these devices are configured to be placed directly at the bottom of the prize ball tank, and the prize balls in the prize ball tank are always stored in multiple storage areas provided on the rotating body (prize ball case). The balls are stored in all of the storage sections except for some storage sections corresponding to the ejection section for the prize balls.

[Problems to be Solved by the Invention] These conventional prize ball ejecting devices are disposed at the bottom of the prize ball tank, so they do not interfere with the back mechanism board of the pachinko machine that has been used up until now, such as the prize ball ejection route. requires major design changes. In addition, the rotating body has
Since prize balls are always stored in all the storage parts except for the prize ball ejection part, a large drive source must be used to rotate the rotating body, and the entire device becomes large. The structure without the ball is a big deal.

Therefore, an object of the present invention is to provide a prize ball ejecting device for a pachinko machine that can be used without major design changes to the back mechanism plate that has been used up to now, does not require a large drive source, and can easily remove balls. It is to provide.

[Means for Solving the Problems] The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 5 corresponding to embodiments.

The present invention comprises a rotating body 36 which is rotated by a motor 38 at a constant angle, and has a plurality of vertical through holes 37 arranged concentrically at equal intervals, each housing a predetermined number of prize balls; It is provided with a supply path 29 that corresponds to a part of the vertical through hole 37 of the rotating body 36 and supplies the prize ball thereinto.

Further, a valve plate 4 is provided below the vertical through hole 37 corresponding to the supply path 29 and is normally openable and closable.
Ball extraction port 4 closed by 3a, 43b
1a, 41b, and a vertical through hole 3 provided below the rotating body 36, excluding the ball extraction ports 41a, 41b.
A discharge port 4 corresponds to the rotation locus of 7 and discharges the prize ball stored inside the vertical through hole 37.
2a and 42b.

[Function] In the rotating body 36, a predetermined number of prize balls are always stored in some vertical through holes 37 corresponding to the supply path 29. The rotating body 36 rotates by a fixed angle each time a prize ball is generated, and as the rotating body 36 rotates, the vertical through hole 37 in which the prize ball is stored opens into the discharge port 42.
a, 42b, and the prize ball stored therein is discharged. At the same time, the vertical through hole 37 in which no prize balls are stored moves to a position corresponding to the supply path 29, and a predetermined number of prize balls are stored therein.

In this way, by rotating the rotating body 36 by a constant angle, the ejecting operation of the prize balls can be performed continuously. Furthermore, if the valve plates 43a and 43b are set in a free state, the prize ball supplied from the supply path 29 to the vertical through hole 37 will be moved by its own weight to the valve plates 43a and 43b.
The ball can be easily removed by pressing down and falling from the ball removal ports 41a and 41b.

A slide plate 45 for opening and closing 1a and 41b is provided.

The slide plate 45 has its front and rear edges fitted into the guide grooves 46 and slides on the upper surface of the bottom wall of the case 35, and has openings 4 corresponding to the ball extraction ports 41a and 41b.
7 and holes 48 that correspond to the discharge ports 42a and 42b are formed. The opening 47 is the ball extraction port 41a, 4
The hole is chosen to be larger than the planar shape of 1b. The valve plates 43a and 43b are fitted with a plumbum 49 at their lower end, and the plummet 49 normally positions the upper end of the valve plate 43a, 43b above the opening 47 of the slide plate 45, as shown by the solid line in FIG. is biased to rotate.

An engagement hole 50 is formed at one end of the slide plate 45, into which a tip protrusion 53 of a rotating piece 52 pivotally attached to the side edge of the mechanism plate 22 via a shaft 51 is engaged. Further, the lower end of a connecting rod 54 is pivotally attached to the rear end of the shaft 51 of the rotating piece 52, and the upper end of this connecting rod 54 is latched to a pin 56 of an operating plate 55 provided on the side surface of the mechanism plate 22. . Further, a small hole 59 is bored in the front frame 2 for operating the actuating plate 55 from the outside with a pin or the like. The actuating plate 55 has a lower end pivotally attached to a horizontal shaft 57 so as to be freely rotatable in the front and rear direction.
A coil spring 58 wound around the horizontal shaft 57 biases the connecting rod 54 in the upward direction as shown by the solid line in FIG. As a result, the slide plate 45 is pushed by the rotating piece 52 and placed in the position shown by the solid line in FIG. 41a,

The winning ball detection switches 32 and 33 are each electrically connected to a step motor 38 via a control device. In the case of this embodiment, the winning ball detection switches 32 and 33 each output a pulse each time a winning ball is detected. Then, the pulses are sent to the control device, and added and stored in the respective counters. On the other hand, a drive signal is output from the control device, and the drive signal of the winning ball detection switch 32 rotates the step motor 38 by 2 steps with each step being 45 degrees.
After the step motor 38 is rotated by 45 degrees by one step according to the drive signal, the detection circuits are respectively activated. Then, by the operation of this detection circuit, the added and stored numerical value is set to be subtracted.

Next, the operation of this embodiment will be explained. When a game ball hit onto the game board 9 enters the starting winning slot 12, the winning ball passes through the winning ball passage 26, is detected by the winning ball detection switch 33, and is then led to the prize ball discharge gutter 31. , lower ball saucer 6 as part of the prize ball
is discharged. And winning ball detection switch 32
The step motor 38 is driven by the signal from
rotated by degrees. When the rotating body 36 is rotated 45 degrees,
Two vertical through holes 37, 37a, 3 in which three prize balls are housed, facing the introduction holes 40a, 40b.
7b is moved to a position that coincides with the discharge ports 42a and 42b, so that a total of six prize balls, three each stored there, are discharged through the prize ball discharge gutter 31 at the top as shown by the chain line in FIG. The ball is discharged into the ball tray 5. At the same time, the vertical through hole 37 in which the prize ball is not stored,
Since the balls 37c and 37d are moved to positions opposite the introduction holes 40a and 40b, three prize balls are stored in each of the vertical through holes 37, 37c and 37dd in preparation for the next discharge.

Furthermore, when a game ball hit onto the game board 9 enters the variable winning device 13 or the general winning slot 14, the winning ball passes through the winning ball space 25 of the mechanism board 22 and is collected in the winning ball collecting section 23. After being detected by the winning ball detection switch 32, it flows into the prize ball discharge gutter 31 and is discharged into the lower ball tray 6 as part of the prize balls.
Then, the step motor 38 is driven by a signal from the winning ball detection switch 32, and the rotating body 36 is rotated two steps at a time of 45 degrees, thereby ejecting six prize balls for a total of 12 prize balls.

In addition, when removing the bulbs after closing, etc., a pin or the like is inserted into the small hole 59 from the front side of the front frame 2 and the operating plate 55 is pressed to tilt it forward against the coil spring 58. As a result, the connecting rod 54 is pushed down by the pin 56 as shown by the chain line in FIG. let Therefore, the valve plate 4 at the side edge of the opening 47 of this
The locking with the upper tips of 3a and 43b is released, and the prize ball accommodated in the vertical through hole 37 from the introduction holes 40a and 40b is pushed by the weight of the ball into the valve plates 43a and 43b.
The ball is pushed down to open the ball extraction ports 41a and 41b, and the ball falls into the ball extraction gutter 34 and is extracted.
Then, when the ball extraction is completed, the valve plates 43a, 43b are returned to the position where the ball extraction ports 41a, 41b are closed by the weight 49. Therefore, the actuating plate 55 is pressed again to move the upper part of the valve plates 43a, 43b. The tip is received in the opening 47 of the slide plate 45. This allows the player to return to a normal state where the ball is not removed.

[Effects of the Invention] As described above, according to the present invention, the prize balls are ejected by shifting the vertical through hole 37 by rotating the rotating body 36 at a constant angle, and at the same time, some empty balls corresponding to the supply route are ejected. The prize ball is stored only in the vertical through hole 37 in preparation for the next discharge. Therefore, the rotating body 3
6, the prize balls are always stored only in some of the vertical through holes 37 that correspond to the supply route, so a large force is not required to rotate the rotating body 36, so the motor used is It is small and the entire device can be downsized.

In addition, ball extraction ports 41a and 41b are provided below the vertical through hole 37 that corresponds to the supply path, and the ball extraction ports 41a and 41b are opened and closed by valve plates 43a and 43b, so that one-touch operation is possible. The ball can be completely removed by operation.

Furthermore, as can be broadly understood from FIG. 2, the prize ball discharging device according to the present invention can be disposed at the lower end of the slope of the supply route that leads out the prize balls from the prize ball tank, and therefore, Unique effects such as the ability to commonly use conventional mechanism plates used in general pachinko machines without major design changes are achieved.
