Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electric ball hitting device for a pachinko machine using a rotary solenoid as a driving source.

<Prior Art> A conventional ball hitting device using a rotary solenoid as a driving source connects a variable resistor to the firing operation handle, and adjusts the electric power applied to the rotary solenoid by changing the resistance value of the variable resistor. The flight distance of the ball was adjusted by adjusting the rotational driving force generated by the rotor of the rotary solenoid.

<Problems to be Solved by the Invention> However, with the electric ball hitting device having such a configuration, it has not been possible to adjust the flight distance of the ball as desired by the player. In other words, since intermittent power is applied to the rotary solenoid, it is difficult for the firing rod to constantly contact the stopper when the rotary solenoid is not energized, and therefore the rotation start position of the firing rod for the next firing operation is difficult to maintain. were not aligned, and it was not possible to stabilize the firing force of the firing rod. Furthermore, simply electrically adjusting the power applied to the rotary solenoid has a small flight distance adjustment range, making it impossible for the player to adjust the range desired by the player. Furthermore, when the flight distance of the ball is adjusted by electrical means, the internal resistance changes due to the heat generated by the variable resistor as the game progresses, which tends to cause variations in the increase or decrease in the applied power depending on the resistance value of the firing operation handle. As a result, the launch force of the ball became unstable and it was not possible to make delicate adjustments to the flight distance.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes a firing rod that rotates to hit a ball with its firing portion facing the firing position of the guide rail and is connected to a rotary solenoid. The front frame of the pachinko machine is provided with a ball adjustment operation section that is rotatably held and operated by a player, and a switch mechanism that opens and closes by rotating the ball adjustment operation section; An electrical control device that applies intermittent power to the rotary solenoid when energized is connected, and one end of the mechanical biasing member is mechanically connected to the elastic adjustment operation section, and the firing rod is activated when not energized. The other end of the mechanical biasing member is mechanically connected to the firing rod so that it is in a standby state when it hits the rear stopper.

<Operation> With the above-described configuration, the present invention uses the constant rotational force of the rotary solenoid after subtracting the biasing force of the mechanical biasing member that acts in the opposite direction to the rotational force of the rotary solenoid, and then generates the remaining force. The firing rod is rotated as a force, and the rotational force of the firing rod is adjusted by rotating the bullet adjusting operation section and mechanically adjusting the urging force of the mechanical urging member.

Further, in the present invention, the mechanical biasing member brings the firing rod into contact with the stopper when the power is not energized, so that the firing rod waits at the same position every time.

<Examples> The present invention will be described below based on examples shown in the drawings.

As shown in Figure 1, the pachinko machine has a supply tray 1.
Pachinko balls thrown into the game are hit one by one by an electric ball hitting device 2 along a guide rail 3 to a playing section of a game board 4.

As shown in FIG. 2, the electric ball hitting device 2 includes a switch mechanism 7 that starts the ball hitting device 2 by rotating a ball adjustment operation section 6 provided on the front frame 5.
It is composed of a rotary solenoid 8, a firing rod 10, etc., which is directly rotated by the rotor 9 of the rotary solenoid 8, and one end of a mechanical biasing member 11 such as a coil spring is mechanically connected to the firing rod 10. The other end of the biasing member 11 is connected to the bullet adjustment operation section 6 described above, so that the biasing force of the biasing member 11 can be adjusted in accordance with the amount of rotation of the bullet adjustment operation section 6.

Therefore, when playing a game with the pachinko machine having the above-mentioned configuration, when pachinko balls are placed in the supply tray 1 and the ball adjusting operation section 6 is rotated, the switch mechanism 7 is electrically connected and the rotary solenoid 8 is turned on. is started, one pachinko ball is supplied to the firing position 13 at the lower end of the guide rail 3 by a known ball feeding device 12, and the ball is automatically delivered to the game board 4 by the firing rod 10 connected to the rotary solenoid 8. , the bullet is fired with the firing force adjusted by the bullet adjusting operation section 6.

The rotary solenoid 8 provided as a drive source for the ball-striking device 2 has an excitation coil 15 wound with a conductive wire around a coil bobbin 14 attached to each opposing magnetic core 16 to form opposing magnetic poles 17 and 17'. The rotor 9 is placed in a magnetic field 18 that is generated by the magnetic field 18. Then, the lower end of the firing rod 10 is fixed to the rotating shaft 19 of the rotor 9 whose both ends are supported by brackets 31, 31, and one end of the biasing member 11 is connected to the middle of the length of the firing rod 10 to apply the biasing force. The rope connected to the other end of the member 11 is wound around a take-up pulley (not shown) of the ball adjustment operation section 6 and fixed. Therefore, when the rotary solenoid 8 is not energized, the firing rod 10 is pulled backward by the urging member 11 and comes to rest in a standby state when it hits the stopper rubber 30, as shown by the solid line in FIG. do. When the rotary solenoid 8 is activated, the firing rod 10 rapidly rotates in the direction of the arrow in FIG. After firing the pachinko ball, the third
As shown by the chain line in the figure, it comes into contact with the stopper rubber 30' and stops. The firing rod 10 that has fired the pachinko ball at the firing position 13 in this way is
It rotates back due to the urging of the urging member 11 and returns to the standby state.

When adjusting the flight distance of a batted ball in the above-mentioned electric ball hitting device 2, the amount of rotation of the ball adjusting operation section 6 is adjusted to adjust the biasing force of the biasing member 11 to change the rebound force. That is, in this embodiment, since the rotational force of the rotary solenoid 8 is constant and the urging force of the urging member 11 acts as a resistance force of the rotary solenoid 8, the urging member 1
When the biasing force 1 is increased, the rotational force of the firing rod 10 is weakened. Therefore, when the ball adjusting operation unit 6 is rotated in a direction to increase the biasing force of the biasing member 11, the firing force of the batted ball is weakened according to the amount of rotation, and the flight distance of the batted ball is adjusted according to the amount of rotation. Can be shortened. On the other hand, when the biasing force of the biasing member 11 is weakened by operating the bullet adjustment operation section 6, the resistance force acting on the rotary solenoid 8 is reduced, so that the amount of rotation of the bullet adjustment operation section 6 is reduced. The distance the ball travels becomes longer.

As shown in FIG. 4, the rotary solenoid 8 that rotationally drives the firing rod 10 as described above is energized to the excitation coil 15 by an electrical control device such as an oscillator that oscillates 30 to 100 times per minute. be done. In Figure 4, 21 is a power supply stepped down to 24V or less, and 22 is a unidirectional three-terminal thyristor (hereinafter referred to as
23 is a silicon bidirectional switching element connected to the gate of SCR, 24 and 25 are capacitors, 26 and 27 are resistors, 28 is a diode for charging the capacitor 25, and 29 is also used to adjust the amount of charging current. By doing so, the silicon bidirectional switching element 23 becomes conductive, in other words, the SCR2
The variable resistor 29 is a variable resistor that can appropriately adjust the interval between energization of the excitation coils 15 and 15' by the coils 2, and the resistance value of the variable resistor 29 can be adjusted by operating the operating section 29' provided on the surface of the front frame 5. It is adjustable. Therefore, when the player operates the bullet adjustment operation section 6 to make the switch mechanism 7 conductive and energize the excitation coils 15 and 15',
The rotor 9 and the firing rod 10 rotate due to the strong magnetic force generated in the magnetic cores 16 and 16', and the firing section 20 fires the pachinko ball at the firing position 13.
At the same time as the SCR 22 becomes conductive and the excitation coils 15, 15' are energized, the charge in the capacitor 25 is discharged.
Voltage drops. When the voltage of the capacitor 25 decreases, the silicon bidirectional switching element 23 becomes non-conductive and the SCR 22 is de-energized, so the excitation coils 15 and 15' are demagnetized and the firing rod 1
0 is returned by the biasing member 11. Furthermore, when the silicon bidirectional switching element 23 becomes non-conductive, the capacitor 25 starts to be charged again, and when the charge potential of the capacitor 25 exceeds a certain voltage (for example, 6V), the silicon bidirectional switching element 23 and the SCR 22 become conductive again. Excitation coil 15,1
5' is applied, and the ball is hit by the firing rod 10. The variable resistor 29 is used to adjust the interval between energization of the excitation coils 15 and 15' by changing the amount of energization to the capacitor 25 during the repetition of the above-described oscillation action. Therefore,
By operating the operating section 29', the variable resistance 29
When the resistance value of excitation coil 15,1 is changed,
The desired number of shots can be adjusted by changing the interval between energization to 5'.

Note that the mechanical biasing member in the present invention is not limited to being directly connected to the firing rod, and one end of the mechanical biasing member may be connected to a portion that rotates integrally with the firing rod.

<Effects of the Invention> As explained above, according to the present invention, the biasing force of the mechanical biasing member acting in the opposite direction to the rotational driving force of the rotary solenoid is subtracted from the constant rotational driving force of the rotary solenoid. The remaining force is used to rotate the firing rod to cause the ball to be fired, and the ball adjusting operation section is operated to increase or decrease the biasing force of the mechanical biasing member, thereby mechanically adjusting the resilient force of the firing rod. , the flight distance of the ball can be adjusted within a wide range as desired by the player. Furthermore, when the rotary solenoid is not energized, the mechanical biasing member brings the firing rod into contact with the stopper and puts it in a standby state every time, so that the starting position of the firing operation of the firing rod can be kept constant every time. Therefore, the amount of rotation of the firing rod is always constant, and the ball can be stably fired based on stable rebound energy, thereby preventing so-called uneven flight.

Further, since the ball hitting device according to the present invention uses a rotary solenoid as a drive source, the structure is simple and the number of components is reduced, so it can be downsized and is less likely to break down.
