Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball launching device for a ball game machine that launches a ball based on a turning operation of a turning operation means.

[Prior Art] Conventionally, in a ball-and-ball game machine such as a pachinko game machine, a driving means such as a motor is driven based on a turning operation of a turning operation means (dial), and a firing lever is fired by a driving force of the motor. The striking portion is rotated in the direction in which the striking portion retreats against the force of the above, and then the striking portion is rapidly rotated and returned in the direction in which the striking portion moves forward by the firing spring, and the striking portion strikes the ball of the firing portion. 2. Description of the Related Art A ball launching device that fires a ball is known.

[Problems to be Solved by the Invention] However, in the above-described conventional ball launching device for a ball-and-ball game machine, in order to maintain a constant flight distance of the ball fired by the ball launching device, a rotating operation means (dial) is used. Although coins and matchsticks are fixed between adjacent gaps, the edges of the gaps are scratched by coins, etc.
In some cases, the match rod is broken and pinched by the gap, thereby making the rotation of the rotation operation means (dial) difficult.

In addition, even if the dial is fixed with coins or match sticks in this way, a voltage drop due to an increase in load when a special game (big hit) occurs, a drop in supply voltage due to an increase in power consumption of ordinary households in the evening, etc. As a result, the supply voltage to the launching device may fluctuate and the flight distance of the ball may not be kept constant.

Further, even if the supply voltage to the launching device is kept constant, the launching device may generate heat with the passage of time, which may change the firing force and change the flight distance.

As described above, if a coin or the like is sandwiched in the gap adjacent to the rotating operation means and the gap is damaged or the rotation becomes less relieved, it must be repaired, and it is not possible for the game store. On the other hand, there is a problem that the profit is brought, and on the other hand, there is a problem that the interest in the game is reduced because the flying distance of the shooting ball cannot be kept constant according to the intention of the player.

The present invention has been made in order to solve these problems. Even if a coin or the like is not sandwiched in a gap portion adjacent to the rotating operation means (dial), the supply voltage to the firing device changes. It is another object of the present invention to provide a ball launching device for a ball-and-ball game machine in which a flight distance of a shooting ball can be always kept substantially constant according to a player's intention.

[Means for Achieving the Object] In order to achieve the above object, a ball launching device for a ball game machine according to the present invention electrically drives a ball supplied to a launch portion (410) of a launch rail (430). A firing means (for example, a firing means (for example,
A launch device 420), a launch operation means (for example, launch operation means 300) capable of changing the amount of power to the electric drive source, and a sphere based on a change in the amount of power to the electrical drive source. A ball launching device (for example, a launch operation device) of a ball and ball game machine (for example, a pachinko gaming machine 1) provided with a launch adjusting device (for example, a variable drive power supply device 760) for adjusting the launching force.
In a device including 300, a launch device 420, and a launch control device 700), a launch sphere detection unit (for example, a launch sphere detector) that detects a sphere that has been fired by the launch unit before reaching the game area at a predetermined position. 440); a firing speed calculating means (830) for calculating firing speed information relating to the speed of the firing sphere passing through the predetermined position based on a detection signal from the firing sphere detecting means; Launch speed setting means (840) for setting reference launch speed information relating to the reference launch speed
Firing speed comparing means (850) for comparing the reference firing speed information set by the firing speed setting means with the firing speed information calculated by the firing speed calculating means.
And wherein the firing adjusting means corrects the firing speed of the sphere fired by the firing means to the reference firing speed set by the firing speed setting means based on the comparison result by the firing speed comparing means. It is characterized in that the amount of power is changed.

The ball launching device of the ball-and-ball game machine includes a launching speed setting switch (400) that allows a player to appropriately select an arbitrary launching speed from among launching speeds during a game that is changed by operation of the launching operation means, The firing speed setting means may set reference firing speed information based on the firing speed selected by the firing speed setting switch.

[Operation] A sphere that has been fired by the firing means and has not yet reached the game area is detected at a predetermined position by the firing sphere detection means, and based on the detection signal, the firing speed calculation means causes the firing sphere to pass through the predetermined position. Calculates the launch speed information about the speed. On the other hand, the firing speed setting means sets reference firing speed information on the reference firing speed of the ball passing through the predetermined position. Then, the firing speed comparing means performs a comparison process between the reference firing speed information set by the firing speed setting means and the firing speed information calculated by the firing speed calculating means, and based on the comparison result, the firing adjusting means Changes the power amount so that the firing speed of the ball fired by the firing means is corrected to the reference firing speed set by the firing speed setting means. As a result, even if the power supplied to the firing device changes, the firing speed of the ball is always maintained substantially at the reference firing speed set by the firing adjusting means, and the flight distance is always maintained substantially constant.

A switching contact portion 393 that can come into contact with the contact piece 396 is provided, and is rotatably supported by pins 399 on the back side of the firing operation device substrate 120.

The setting is displayed by the lamps 405 and 405 via the setting completion display unit 406.

The firing control mechanism 1000 is configured as described above, and the rotating operation member 320 is always rotated and returned to the fixed angle position by the returning force of the returning spring 381 (FIG. 5). Then, the switch pressing projection 371 of the drive pulley 370 attached to the rotating shaft 321 is in a state of being raised as shown in the figure, and the tip end thereof is in contact with the operating contact portion 392 of the single-shot operation member 390. The single-hitting operation member 390 is rotated in a direction in which the contact portion 392 contacts the state where the ascending force is applied, and thereby the operation contact portion 392 side rises. Then, the starting detector 395 is provided by the switching contact portion 393 on the tip side.
When the free end side of the contact piece 396 is pushed up to be in an OFF state, the hitting ball firing device 420 is in a stopped state.

In this state, when the rotation operation member 320 is rotated clockwise (counterclockwise in FIG. 10) when viewed from the front side,
The drive pulley 370 is rotated integrally therewith, and the switch pressing projection 371 is lowered. As a result, the pushing force of the switch pressing projection 371 on the operating contact portion 392 side of the single-shot operation member 390 is released. With the release of the lifting force, the single-shot operation member 390 is rotated by its own weight in the direction in which the operation contact portion 392 side is lowered. By its rotation,
The push-up force of the contact piece 396 of the activation detector 395 by the switching contact portion 393 is released, whereby the activation detector 395 is turned on (ON), and the operation of the hitting ball firing device 420 has the function of the touch plate. It is operated on condition that the human body touches the handle member 301 to fire the game ball of the firing unit 410.

The rotation angle associated with the rotation operation of the rotation operation member 320 is detected by the rotation angle detection device 380, and as the detection signal is input to a voltage variable unit 750 described later and the rotation angle increases, The launch speed of the game ball is controlled to increase.

When it is desired to stop the firing of the game ball performed in this manner, if the user releases the rotating operation member 320, the rotating operation member 320 is rotated and returned to the fixed angle position by the return spring 381. The firing of the game ball is stopped.

However, if it is desired to temporarily stop the launch of the game ball while keeping the rotation angle of the rotating operation member 320 in such a good firing state, by pressing the operation portion 391, the single-shot operation member 3
90 turns the switching contact portion 393 in the ascending direction, pushes up the contact piece 396 of the activation detector 395 at the switching contact portion 393, and turns off the activation detector 395, and thereby the firing device The operation of 420 is stopped. Then, when the game ball is no longer fired, if the pressing operation of the operating member 391 is released, the single hitting operating member 390 rotates in a direction in which the switching contact portion 393 side descends, and the switching contact portion 3
The pressing of the contact piece 396 of the activation detector 395 by 93 is released, and the activation detector 395 is turned on to return the firing device 420 to the operating state, whereby the launch of the game ball is started again.

Then, while maintaining the rotation angle of the rotation operation member 320 in such a favorable firing state, the single-shot operation member 39
If the operation of releasing the pressing by appropriately pressing the operation unit 391 of 0 is repeated, a single shot is performed for that operation.

It is a flowchart which shows the program of the launch control processing procedure of the game ball performed by 0, and this program is performed once for every predetermined period (for example, 10 ms). In the figure,
Sn (n = 1, 2,...) Indicates each step of the flow.

First, when the pachinko gaming machine is turned on, in step S10, the firing solenoid 421 and the ball supply solenoid 530 are turned off, and the firing interval flag, the solenoid flag, and the firing speed setting flag are lowered (firing interval flag ← 0, solenoid flag ← After performing initial settings such as 0, firing speed setting flag ← 0), the process proceeds to step S11.

In step S11, it is determined whether or not the stop signal from the management device 2000 has been input. If it is determined that the stop signal has not been input, the metal frame based on the OFF state of the metal frame open detector 270 in step S12. It is determined whether or not 222 is open with respect to the front frame 10. As a result, when it is determined that the metal frame 222 is not opened, the process proceeds to step S13, and whether the pachinko gaming machine 1 is opened with respect to the machine frame 100 based on the OFF state of the gaming machine open detector 260 in step S13. Determine whether or not. When it is determined that the pachinko gaming machine 1 is not opened with respect to the machine frame 100, the process proceeds to step S14, and in step S14, the player contacts the touch plate 340a and the detection signal output of the touch detection unit 720 changes the contact state. It is determined whether or not the indicated ON state has been reached. When the detection signal output from the touch detection means 720 is turned on, it is determined that the player is turning the turning operation member 320 while touching the handle member 340 having the touch plate 340a function, and The process moves to S23 (FIG. 14 (B)).

On the other hand, when it is determined in step S11 that a stop signal has been input from the management device 2000, when it is determined in step S12 that the metal frame 222 is open, in step S13, the pachinko gaming machine 1 is opened with respect to the machine frame 100. When it is determined that the touch panel 340a has been touched, or when at least one of the conditions when a detection signal indicating that the human body is not in contact with the touch plate 340a is output in step S14, the ball firing and the ball It is determined that there is no condition for continuing the supply, and the process proceeds to step S15. In step S15, it is determined whether or not the setting flag indicating dial (flying distance) fixation is "1" (firing speed setting flag = 1). When it is determined that the firing speed setting flag is "1", it is determined that the flight distance has been set, and the process proceeds to step S16. In step S16, the firing speed setting switch 400 is pressed and a rising signal is output. It is determined whether or not it has been performed. In this state, when it is determined that the firing speed setting switch 400 is pressed and a rising signal is output, it is determined that the player is about to release the fixing of the dial (flying distance), and the process proceeds to step S17, and is set in step S17. The flag is lowered (setting flag ← 0), the setting completion display lamp 405 is turned off (turned off) in step S18, and the process proceeds to step S19. When the firing speed setting flag is "1" in step S15 (that is, when the firing speed setting flag is 0), it is determined that the flight distance is in a flight distance unset state in which the flight distance can be freely varied. Step S1 as it is
Move to 9, and in step S16 the firing speed setting switch 40
When it is determined that the rising signal has not been output from 0, it is determined that there is no change in fixing and releasing of the dial, and the process directly proceeds to step S19. In step S19, the firing interval control means 820 outputs an operation stop signal to the ball supply solenoid 530 to stop the ball supply solenoid 530, and then proceeds to step S19.
At 20, the firing interval control means 820 outputs an operation stop signal to the firing solenoid 421 to stop the firing solenoid 421 (see FIG. 15). Next, in step S21, the firing interval flag is lowered (firing interval flag ← 0), and in step S22, the solenoid flag is lowered (solenoid flag ← 0), and the process returns to step S11.

In step S23, it is determined whether or not the firing speed setting flag is “1”, and the firing speed setting flag is “1”.
Is not set (when the firing speed setting flag = 0)
Determines that the flight distance has not been set, and determines whether or not a rising signal has been output from the firing speed setting switch 400 in step S24. When it is determined that the firing speed setting switch 400 has been pressed and the rising signal has been output, the player determines that the present flight distance of the hit ball is to be maintained and the step is performed.
In S25, the firing timer storage value at this point is stored as a firing timer set value. This firing timer storage value is obtained by counting the time that the ball passes through the firing ball detector 440 after the ball is fired (the firing solenoid 421 is turned on), and the flight distance of the hit ball is calculated by measuring the time. . Next, in step S26, a firing speed setting flag is set to indicate that the flying distance has been set (firing speed setting flag ← 1), and in step S27, the setting completion display lamp 405 is turned on (lit), and the player is dialed. Notify that it has been fixed. On the other hand, when it is determined in step S23 that the firing speed setting flag is "1", it is determined that the flight distance has already been set, and in step S28 a rising signal is output from the firing speed setting switch 400. Determine whether or not. In this state, when it is determined that the firing speed setting switch 400 is pressed and the rising signal is output, it is determined that the player has pressed the setting button 401 to release the fixed flight distance, and the firing speed setting flag is lowered in step S29. T (firing speed setting flag ←
0) The flying distance is set in a flying distance unset state in which the flying distance can be varied with the dial, and the setting completion display lamp 405 is turned off (turned off) in step S30, and the process proceeds to step S31. On the other hand, when it is determined in step S24 and step S28 that the rising signal has not been output from the firing speed setting switch 400, it is determined that there is no change in fixing and releasing the dial (flying distance), and the process directly proceeds to step S31.

In step S31, it is determined whether or not the firing interval flag is "1" (firing interval flag = 1). As a result, when the firing interval flag is “1” (that is, when the firing interval flag is set down), a firing start request is issued and it is determined that the ball can be fired and the ball can be supplied. Then, the process shifts to step S32, and in step S32, it is determined whether or not the firing speed setting flag is “1”. As a result, when the firing speed setting flag is not “1” (when the firing speed setting flag = 0), it is determined that the dial is not fixed, and the process proceeds to step S33. Rotating operation member sent out
The rotation angle (rotation amount) of 320 is read, and a power supply voltage for the firing solenoid 421 corresponding to the rotation angle is selected in step S34. When it is determined in step S32 that the firing speed setting flag is "1", it is determined that the dial (flying distance) has been set and the firing speed storage value needs to match the firing speed setting value. Then, the process proceeds to step S35. In step S35, the firing timer storage value as the firing speed storage value is subtracted from the firing timer setting value as the firing speed setting value, and the power supply voltage for the firing solenoid 421 is corrected based on the difference in step S36.

In step S37 (FIG. 14 (C)), the firing interval control means 8
The operation command signal is output from 20 to the firing solenoid 421, and the firing solenoid 421 is operated (see FIG. 15).
Start the firing timer at 38. This allows the firing unit
The ball supplied to 410 is hit and fired by the forward force of the firing rod 423 when the firing solenoid 421 is excited. As described above, since the rotation angle of the rotation operation member 320 is electrically detected and the resilience of the firing solenoid 421 is varied based on the signal, vibration is directly transmitted to the handshake member 340 due to the resilience. The game is performed comfortably without any trouble.

Next, in step S39, the firing interval control means 820 outputs an operation command signal to the ball supply solenoid 530 to operate the ball supply solenoid 530 (see FIG. 15). Then, each time a shooting operation is performed by the hit ball firing device 420, one game ball is sent to the firing unit 410 one by one.

In step S40, a firing interval flag is set to indicate that firing has been started (firing interval flag ← 1), and in step S41, an interval timer for measuring the time of the firing interval is started. Then, the solenoid timer for the ON time is started, and the process returns to step S11 (FIG. 14 (A)) again.

On the other hand, if the firing interval flag is "1" in step S31 (FIG. 14 (B)), it is determined that the firing has already been started, and the flow shifts to step S43. It is determined whether or not is turned on. as a result,
If it is determined that the firing sphere detector 440 is turned on, the firing timer value at that time is stored in step S44, and step S44 is performed.
Move to 45. When it is determined that the firing ball detector 440 is not turned on, it is determined that there is no condition for storing the firing timer value, and the process directly proceeds to step S45. In step S45, it is determined whether or not the solenoid flag is "1" (solenoid flag = 1). As a result, when the solenoid flag is not "1" (that is, when the solenoid flag is lowered), the process proceeds to step S46, and in step S46, it is determined whether or not the time of the solenoid timer set in step S42 is up. Is determined. As a result, when it is determined that the time of the solenoid timer has not expired, it is determined that the firing solenoid 421 and the ball supply solenoid 530 are still in operation, and the process returns to step S11. If it is determined that the solenoid timer has timed out, then in step S47 the firing interval control means 8
An operation stop signal is output from 20 to the ball supply solenoid 530 to stop the ball supply solenoid 530, and in step S48, a firing stop signal is output from the firing interval control means 820 to the firing solenoid 421 to stop the firing solenoid 421. Next, in step S49, a solenoid flag is set (solenoid flag ← 1), and the process returns to step S11.

When the solenoid flag is "1" in step S45, the process proceeds to step S50, and in step S50, it is determined whether or not the interval timer set in step S41 has expired. As a result, if it is determined that the interval timer has not timed out, the process returns to step S11. If it is determined that the time has elapsed, it is determined that an appropriate firing interval has been secured, and the firing interval flag is lowered in step S51 (the firing interval (Flag ← 0), the solenoid flag is lowered in step S52 (solenoid flag ← 0), and step S1
Return to 1.
