Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball dispensing apparatus for a pachinko game machine that dispenses pachinko balls by rotating a lead screw.

[0002]

2. Description of the Related Art Various types of ball dispensing devices for pachinko gaming machines are known, for example, Japanese Patent Laid-Open No. 5-137.
The ball dispensing device shown in FIG. 841, as shown in FIG.
The pachinko ball p is arranged to flow down from the prize ball tank by its own weight, and a ball receiving shelf b is provided at the lower end of the ball guiding tube a. A lead screw c provided on one side of the ball receiving shelf is driven by a motor d. By rotating by the operation of
The pachinko ball p on the ball tray is slid toward the outlet e.

In the lead screw type ball dispensing apparatus described above, the pachinko ball p connected to the ball guiding cylinder a is used.
This makes it difficult for the pachinko balls p on the ball receiving shelf b to move in the direction of the flow-down opening e. Therefore, there is a problem that a large load is applied to the motor d when the lead screw starts to rotate. For this reason, the lead screw must be rotated so as to overcome the load, so that a motor having a large required starting torque is required, and the manufacturing cost may be increased.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems and to make it possible for a lead screw type ball dispensing device to always operate smoothly.

[0005]

For this purpose, a ball dispensing device in a pachinko gaming machine according to the present invention is provided with a ball receiving shelf at a lower end of a ball introducing cylinder for aligning and flowing down pachinko balls, and providing one of the ball receiving shelves. A lead screw is provided substantially horizontally on the side, a dropout is opened at the end of the ball receiving shelf, and pachinko balls on the ball receiving shelf are sent to the dropout by rotating the lead screw. In the ball dispensing device, the ball receiving shelf is formed so as to be inclined downward toward the outlet. Further, the present invention is characterized in that in the above-mentioned ball dispensing device, an inclined wall is formed which urges the pachinko ball in a feed direction by a lead screw when the pachinko ball comes into contact with a lower end portion of the ball introducing cylinder. Further, the present invention is characterized in that in the ball dispensing device, the ball introducing cylinder is formed in an inclined shape so as to urge the pachinko ball in a feed direction by a lead screw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a back view of a pachinko gaming machine, 1 is a prize ball tank, and 2 is a ball payout device that receives supply of pachinko balls flowing down from the prize ball tank by its own weight. 2 is a horizontal sectional view of the ball dispensing device, FIG. 3 is a sectional view taken along line AA, and FIG. 4 is a vertical sectional view. As shown in the figure, the ball dispensing device 2 has a pair of ball introduction cylinders 4 through which the pachinko balls aligned in a row by passing through the straightening gutter 3 can flow down.
a and 4b are provided vertically, respectively, and ball receiving shelves 5a and 5b are provided at the lower end of the ball introducing cylinder. 6 is the ball receiving shelves 5a, 5
This is a lead screw provided horizontally between b. Also, 7a and 7b are the outlets opened at the tip of each ball tray,
Reference numeral 9 denotes a discharge passage formed so as to be continuous below the outlet.

The ball receiving shelves 5a, 5b are formed so as to be gradually inclined downward at an inclination angle α toward the outlets 7a, 7b. The lead screw 6 has a groove depth and a helical pitch such that pachinko balls on the ball receiving shelves 5a and 5b can intervene in the helical groove, and is fixed to the rotating shaft of a motor 8 such as a pulse motor. The motor is driven to rotate in the direction of the arrow.

Reference numeral 11 denotes a ball counting sensor for detecting a pachinko ball that has flowed down from the outlets 7a and 7b and outputting a pulse signal. The rotation of the motor 8 is controlled by the detection of the sensor, and a predetermined number of balls are paid out. I have to.

In the ball dispensing device thus configured, the ball receiving shelves 5a and 5b are formed to be inclined downward, so that the gravity of the pachinko balls supported on the ball receiving shelves 5a and 5b causes the gravity of the outflow openings 7a and 5b. 7B, the lead screw 6 rotates to reduce the load on the motor 8 required to slide the pachinko balls on the ball receiving shelves 5a, 5b toward the outlets 7a, 7b. it can.

On the other hand, in the embodiment shown in FIG. 5, the slanted wall 10 for urging the pachinko balls in the feed direction by the lead screw 6 by contacting the pachinko balls with the lower end portions of the ball introducing cylinders 4a and 4b is formed. It is made. By forming the inclined wall 10 in this manner, the load of the pachinko balls connected in the ball introduction cylinders 4a and 4b is converted in the direction of the ball receiving shelves 5a and 5b. The pachinko balls on the receiving shelves 5a and 5b can be sent more smoothly.

In the embodiment shown in FIG. 6, the ball introduction cylinders 4a and 4b are formed so as to be inclined backward with respect to the feed direction by the lead screw 6 as shown by the angle β in the figure. The pachinko ball flowing down the ball introduction cylinder is directed in the direction of feed by the lead screw. Even in this case, the ratio of the load of the pachinko balls in the ball introducing cylinder on the ball receiving shelves 5a and 5b is reduced, the direction is changed smoothly, and the load on the motor 8 can be further reduced.

In these embodiments, ball receiving shelves are provided on both sides of the lead screw. However, it is needless to say that ball receiving shelves may be provided only on one side.

[0013]

As described above, the ball dispensing device for a pachinko gaming machine according to the present invention has a ball receiving shelf provided at the lower end of a ball introducing cylinder for aligning and flowing down pachinko balls, and a ball receiving shelf is provided on one side of the ball receiving shelf. A ball screw dispenser in which a lead screw is provided substantially horizontally, a dropout hole is opened at the end of the ball receiving shelf, and pachinko balls on the ball receiving shelf are sent to the dropout hole by rotating the lead screw. In the device, since the ball receiving shelf is formed so as to be inclined downward toward the outlet, there is a beneficial effect that the load on the motor is reduced, the manufacturing cost is reduced, and the operation is always performed smoothly. .
