It has an input filter to which each of the above-mentioned sensors and the like are connected, a driver to which each of the above-mentioned solenoids and the like are connected, a CPU that performs signal processing, a crystal oscillator that generates a clock signal, and a power supply unit for power supply. The input filter performs waveform shaping of the output signal of the sensor, the driver amplifies the output signal of the CPU and outputs the amplified signal to a solenoid or the like, and the CPU processes the signal according to a predetermined program to control the discharge of pachinko balls. Although a detailed description is omitted, the discharge control device 902 is connected to a central management device of a game arcade to input a stop signal or the like, and a reset switch is provided on an outer surface.

Next, the operation of the pachinko ball discharging apparatus of this embodiment will be described. This ball discharge control device 902
When the power of the gaming machine 1 is turned on, input processing is first performed, and for example, logic conversion from various detection switches and chattering prevention processing are performed. As the chattering prevention process, for example, there is a process of reading a signal from each detection switch twice by software, etc., and taking into consideration a time constant of noise and the like to prevent chattering.

Next, it is determined whether or not the power is turned on. If the power is turned on, the data stored in the RAM is erased (RA
M clear) and the like, and perform initial settings. This clears the working area of the RAM, sets flags, resets output ports, initializes subroutines, and the like.

On the other hand, it is determined that it is not the first routine execution,
That is, when it is determined that the execution is the second or later execution, the output processing is performed. In this output processing, processing such as outputting data to an output port and outputting a switching signal to a solenoid is performed. Subsequently, a switch input monitoring process is performed to monitor input information of each sensor and the switch. Specifically, output signals of the discharge sensors 730a and 730b, an odd sensor, an overflow sensor, and the like are monitored.

Next, a ball payout start confirmation condition monitoring process is performed to check whether or not the pachinko ball discharge device 804 has set the conditions for starting the discharge for the prize ball or the ball lending. Confirmation is performed based on data such as "there is a ball (safe ball)" and "there is a ball lending request signal".

Then, based on the result of the input monitoring process of each switch, the corresponding safe ball is confirmed and purchased, the prize ball data is transmitted and received, the pachinko ball is discharged, the discharge is completed, the safe ball is paid out and the weight is processed. Perform ball removal processing. Here, the description will be limited to the pachinko ball discharging process directly related to the pachinko ball discharging device according to the present invention. The pachinko ball discharging process is a process of counting the number of discharged pachinko balls and paying out a specified number. Whether the number of pachinko balls discharged by the discharging mechanism 710 is in a state in which “−1” has been subtracted from the specified number. For example, when fifteen prize balls are discharged, “specified number = 15” is determined, and it is determined whether the number of discharged pachinko balls is fourteen. .

When the result of the determination is "No" (for example, when the number is less than the 14th), the operation speed of the pachinko ball discharging device 804 is set to the normal state until the number reaches the 14th, When it comes to the eye, the operation speed is slowed down to slow the discharge of the fifteenth pachinko ball to prevent ball balling, and the pulse motor 750 is accurately stopped.

Here, the operation related to the discharging mechanism 710 of the pachinko ball discharging device 804 will be described. First, pachinko balls are supplied from the storage tank 806 to the guide paths 702a and 702b via the guide path 807. And
The discharge mechanism 710 operates based on a predetermined program control of the CPU.

This operation will be described in detail.
The pachinko ball P that has flowed down from 02a is a sprocket 71
2a is fitted into the cutout 715. At this time, pachinko balls P
As shown in FIG. 3, a ball bearing surface 900 having a notch 715 and an inner surface 7 of a guide passage (ball passage) 702a.
02c.

Therefore, the ball pressure of the pachinko ball P is applied in the direction indicated by the arrow F in FIG.
Since the pressure applied to the inner surface 702c of the sprocket 2a appears as vertical and horizontal dispersion vector components of the vector in the direction of the arrow F, respectively, the sprocket 712a Shaft 711
Can be reduced, and the durability against breakage and wear can be improved.

When the pachinko ball flowing down from the guide passage 702a has a momentum, an impact is generated when the pachinko ball is inserted into the cutout portion 715 of the sprocket 712a, but the impact force is also increased by the inclination of the ball support surface 900. Surface bearing surface 9
00 and the inner surface 702c of the guide passage 702a are dispersed and absorbed, so that a large vertical shock is prevented from being applied only to the sprocket 715 as in the related art, and even if the pachinko ball bounces with its momentum. Since the ball only rebounds in the direction opposite to the arrow F, the pachinko ball does not deviate vertically from the notch as in the prior art, and the so-called idle feeding of the pachinko ball by the sprocket 712a is prevented. Therefore, the specified number of pachinko balls can be accurately discharged, and the reliability of the discharging device can be improved.

The above operation is achieved by the sprocket 712b
The same applies to the discharge of pachinko balls due to. In addition,
Instead of making the cutouts 715 of the sprockets 712a and 712b inclined, as shown in FIGS. 7 and 8, the horizontal ball bearing surfaces 909, 909,.
At one corner of the projection 910, 910 ...
The same operation and effect can be obtained by forming.
That is, if the projection 910 is provided on the ball bearing surface 909,
As shown in FIG. 7, the ball pressure and impact force of the pachinko ball P become a vector in the direction of arrow F by the action of the projection 910, and are dispersed into components in the vertical and horizontal directions. In the same manner as described above, the stress and impact force applied to the sprocket 712 can be reduced.

The notch 71 of the sprocket 712
5, when the pachinko ball is fitted into the stopper mechanism 720 so that the rotation of the gear 713 is allowed, the discharging mechanism 710
The sprocket 712 is rotated by a step motor 750, and the pachinko balls fitted in the cutouts 715 are accurately paid out to the guide passages 702a or 702b. In the case of the pachinko ball discharging process, that is, during rotation of the pulse motor 750, the pulse motor 750
The pulse motor 750 is driven by the two-phase excitation, and when the discharge process is not performed, that is, at the beginning or end of the rotation of the pulse motor 750, the pulse motor 750 is driven by the 2-2 phase excitation. Therefore, at the beginning of rotation or at the end of rotation of the pulse motor 750, a large torque can be obtained from the output of the pulse motor 750, and smooth rotation can be secured.
Can be reduced.

As described above, according to the pachinko ball discharging apparatus according to the present invention, the stress and impact force applied when the pachinko ball is inserted into the sprocket 712 can be reduced, so that the sprocket 712 and the sprocket Accidental damage and abrasion of the rotating shaft 711 can be reduced, and durability can be improved. Further, when the pachinko ball is fitted into the sprocket 712, the pachinko ball does not deviate from the cutout portion 715 of the sprocket 712 even if it bounces, so that the so-called idle feeding of the pachinko ball is prevented, Accurate payout of pachinko balls can improve reliability.

Although slightly different from the gist of the present invention, as shown in FIGS. 9 and 10, each ball bearing surface 912 of the cutout 715 of the sprocket 712a has a curvature adapted to the peripheral surface of the pachinko ball. If a depression is formed, the pachinko ball fits into the notch 715 when it is fitted, and the pachinko ball can be discharged stably.

In the above-described embodiment, the discharging mechanism 71
Although the description has been made of the case where two sprockets 712a and 712b are provided in the 0, it is not limited to this.
One sprocket 712 may be used, or 3
More than one may be provided. Further, the discharge mechanism 7
Although the actuator adopting the pulse motor 750 has been illustrated as the ten actuators, a normal motor may be used.
