Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a pachinko machine that can increase the number of balls that can be fired within a unit time.

<Prior Art> As is well known, the number of balls that can be fired per unit time for pachinko machines is regulated in consideration of the interests of the players and the interests of the gaming parlor, without unnecessarily inciting the gambling spirit. Currently, it is no longer possible to fire more than 100 bullets per minute.

Therefore, in the past, even if a pachinko machine was configured so that the rotation speed of the drive motor of the firing device could be varied to adjust the number of shots per unit time, the maximum number of shots per unit time was 100 shots per 11 minutes. That is, the time required to fire one batted ball is 0.6 seconds, and it is therefore regulated by law to fire a batted ball at a fast rate of one minute.

<Problems to be Solved by the Invention> By the way, in pachinko machines, various efforts have been made to increase the interest of the game. The winning rate is temporarily increased rapidly. In such a pachinko machine, the interest of the game can be further increased by making it possible to win as many balls as possible into the variable prize winning device which is opened to a state where the winning rate is high. However, in the conventional pachinko machine described above, the number of shots fired can only be changed within a range of no more than 100 shots per minute, and the firing device cannot be adjusted to the extent that the game is more interesting.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and it is possible to fire game balls one by one using a drive source and also to fire within a unit time that is a part of the above-mentioned predetermined time. a firing device that can increase or decrease the number of game balls fired; an acceleration switch that allows the player to increase the number of game balls that can be fired in a unit time by the firing device; A firing number calculation means for calculating the number of game balls that can be fired within a unit time based on the number of game balls that can be fired from the firing device within a range that does not exceed the maximum number of game balls that can be fired within the predetermined time. The game ball is further provided with a shot number control means for increasing the number of game balls fired by the firing device using the calculated value of the shot number calculation means.

<Function> When the player operates the acceleration switch, the number of shots calculation means calculates the number of shots that can be fired within a unit time, and the number of shots control means operates the firing device based on this calculated value. The total number of shots within a predetermined time, which is the unit time plus time other than the unit time, is suppressed within a limit value.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

First, the principle of the present invention will be explained with reference to FIG.

Now, if we assume that the balls are fired at uniform intervals,
The number of shots per minute M represents the firing speed on the vertical axis, and its unit can be expressed as [shots/minute].
The maximum number of shots at this rate of fire is limited to 100 shots per minute, so if these are fired at uniform intervals, the maximum number of shots per minute is 100 shots per minute, as shown by the broken line in Figure 1. ] is the firing speed.

Now, if we consider that one minute is divided into four time slots _T1 to _T4 , each of which is a unit of time, for example 15 seconds, the balls are fired at uniform intervals in each time slot, so it is difficult to determine which time slot It can be considered that the firing speed limit for rotary jets is 100 [pieces/minute].

By the way, now the player is playing at uniform intervals for one minute.
Assuming that 80 balls are fired, the balls are fired at a firing speed of 80 [balls/min] in time slots _T1 to _T4 , as shown by the dashed line in FIG. In this way, if the balls are fired at a firing speed of M = 80 [balls/min], there is a margin of ``20'' between the maximum number of shots ``100'' and ``100'' in one minute. However, the number of firings for this extra time is calculated as T <sub>1</sub> for all time slots.
~ There is no need to uniformly allocate and fire T <sub>4</sub> ,
Even if you concentrate on firing at any one of the time slots T <sub>1</sub> to <sub>T 4</sub> , ``100 pieces per minute''
It is possible to satisfy the restriction of firing a batted ball of .

The present invention utilizes this relationship to concentrate the surplus number of shots into one of the time slots T ₁ to T ₄ (for example, T ₂ ), as shown by the solid line in FIG _. Firing speed from 80 [pieces/min]
It is specially accelerated to 160 pieces/minute, thus allowing the player to shoot as quickly as necessary within the maximum number of shots per minute.

A mechanism based on such a principle can be realized by the configuration described below.

In FIG. 2, reference numeral 1 denotes a firing device, which fires a ball along a guide rail 4 onto a game board 5 using a firing rod 3 that is electrically driven with a spring force adjusted by an operation dial 2. A game board 5 having a specific winning hole 6, a center winning device 7, and a variable winning device 8 is made to flow down.

The prize ball is shot 1 from the upper tank 10.
1. The prize balls are discharged to the supply tray 14 through the prize ball discharge device 12 and the prize ball gutter 13. In addition, 15 is a safe ball detector provided at the lower part of the collection gutter 16, and when a safe ball passes, it activates the prize ball discharge device 12 and discharges a certain number of prize balls into the supply tray 14. 1
7 is a saucer.

At the bottom of the outer frame 19 of the pachinko machine 18, a shot number selector 25 is provided alongside the operation dial 2. In this case, the firing number selector 25 includes a "100" selection switch 25A that commands the firing of 100 batted balls per minute, and a selection switch 25B that commands the firing of 90, 80, and 70 batted balls per minute. ,25C,
25D is provided. These selector switches 25A, 25B, 25C, and 25D are composed of key switches, and when one key switch is pressed, the depressed state of that key switch is mechanically locked, and the other key switches are released from the locked state. It is designed so that it can be restored.

On the other hand, the operation dial 2 is provided with an acceleration switch 26. The acceleration switch 26 is configured as a push button switch, and outputs an acceleration command only while being pressed by the player.

The selection output of the firing number selector 25 and the acceleration command output of the acceleration switch 26 are sent to a firing number control circuit 28 as firing number control means shown in FIG. The drive source of the firing device 1 is driven and controlled by its output.

As the firing device 1, as shown in FIG. 4, one having, for example, a rotary solenoid 1A as a driving source can be applied. Rotary solenoid 1A
, the movable element 1B is rotated every time an intermittent pulsed power is applied to the excitation coil, and the firing rod 3 fixed to the movable element is rotated in the firing direction shown by the chain line, thereby firing the lower end of the guide rail 4. A ball 31 located at a position 4A is bounced along a guide rail 4. Note that IC is a return spring provided on the firing rod 3, and ID is a stopper at the return position.

The batted ball 31 from the supply tray 14 is guided to the elevating lever 32B position through the guide gutter 32A of the batted ball supply device 32, and when the firing rod 3 rotates from the firing direction to the return direction, the L-shaped ball 31 fixed to the firing rod 3 protuberance 1E,
By rotating the actuating rod 1G with the elevating lever 32B fixed to the tip via the rotation link 1F, the elevating lever 32B is lowered once and one batted ball is placed on the elevating lever 32B, and then the firing rod 32B
As the ball rises, the ball 31 is dropped into the firing position 4A through the window 32C, thus delivering one ball.

The firing number control circuit 28 sends the outputs of the "100" to "70" selection switches 25A to 25D of the firing number selector 25 to a pulse oscillator 28F constituting a drive output section 28E via backflow blocking diodes 28A to 28D, respectively. It receives the signal and starts oscillating. At the same time, the outputs of the "100" to "70" selection switches 25A to 25D are received by the firing number calculating circuit 288G as a designated firing number signal, and the number of pulses that should be generated in one minute is calculated, and the calculation result is used to prevent backflow. diode 28
It is given as an oscillation frequency command signal to the pulse oscillator 28F via H to 28K.

Here, the pulse oscillator 28F is "100", "90",
"80", "70" selection switch 25A, 25B, 25
When C and 25D were operated, they generated 100, 90, 80, and 70 pulses per minute, respectively,
This pulse output is given to the rotary solenoid 1A via the power control circuit 28L.

The rotary solenoid 1A rotates the firing rod 3 and fires the ball to the game board 5 along the guide rail 4 every time each pulse power of the pulse output arrives.

Note that the power control circuit 28L has an operation dial 2.
An output adjustment signal Y corresponding to the operating rotation angle of the operation dial 2 is given, and thereby the strength of the rotational force of the firing rod 3 of the rotary solenoid 1A can be controlled to adjust the flight distance of the batted ball. There is.

In addition to the above configuration, the output of the acceleration switch 26 is supplied to the shot number calculation circuit 28G as shot number calculation means. The firing number calculation circuit 28G is "100"
~ "70" The difference between the number of shots per minute selected by the selection switches 25A to 25D and the maximum number of shots is calculated, and the number of shots corresponding to this difference is calculated at the time slot in which the output of the acceleration switch 26 arrives. At the next time slot, it is added to the specified number of shots and applied to the pulse oscillator 28F.

That is, when the "100" selection switch 25A is selected, the firing number calculation circuit 28G sends an oscillation frequency command signal to generate 25 pulses in every 15 second time slot _T1 to _T4 . It is given to the pulse oscillator 28F. However, at this time "100"
Since the specified number of shots received from the selection switch 25A is equal to the maximum number of shots "100", there is no difference between the limited number of shots and the specified number of shots, so even if the output of the acceleration switch 26 is given to the number of shots calculation circuit 28G. It is not added to the number of shots assigned to each time slot. Then, the firing device 1 fires the ball at the speed of the firing number specified by the "100" selection switch 25A.

Next, when the "90" selection switch 25B is selected, the firing number calculation circuit 28G selects T ₁ , T ₂ , T ₃ , T ₄ for the time slot, for example, 23, 22, 23.
An oscillation frequency command signal for generating 22 pulses is given to the pulse oscillator 28F. However, at this time "90" selection switch 25B
Since the specified number of shots received from is ``10'' less than the maximum number of shots ``100'', this extra number of shots is set as the specified number of shots ``22'' or ``23'' for the time slot where the output arrives from the acceleration switch 26. The signals are added together and thus provided to the pulse oscillation circuit 28F as an oscillation frequency command signal for one slot containing 32 or 33 shots. However, after such addition is performed for one time slot, only the designated firing number for the remaining time slots is sent from the firing number calculation circuit 28G to the pulse oscillator 28F as an oscillation frequency command signal.

Next, when the "80" selection switch 25C is selected, the firing number calculating circuit 28G gives an oscillation frequency command signal to the pulse oscillator 28F to generate 20 pulses for each time slot. However, at this time, the "80" selection switch 25
Since the specified number of shots received from C is ``20'' less than the maximum number of shots ``100'', this extra number of shots is used as the specified number of shots ``20'' for the time slot next to the time slot where the output arrives from the acceleration switch 26. ” is added, and the pulse oscillation circuit 2 is output as an oscillation frequency command signal for one slot containing 40 shots.
Given to 8th floor. However, even in this case, for the remaining time slots, only the designated firing number is sent from the firing number calculation circuit 28G to the pulse oscillator 28F as an oscillation frequency command signal.

Next, when the "70" selection switch 25D is selected, the firing number calculation circuit 28G issues an oscillation frequency command to generate, for example, 18, 17, 18, and 17 pulses for each time slot. A signal is given to pulse oscillator 28F. However, at this time, the specified number of shots received from the "70" selection switch 25D is "30" less than the maximum number of shots "100", so this extra number of shots is used for the next time slot after the output from the acceleration switch 26. The signal is added to the designated firing number "17" or "18" of the time slot, and is given to the pulse oscillation circuit 28F as an oscillation frequency command signal for one slot containing the firing number of 47 or 48. However, in this case as well, for the remaining time slots, only the command firing number is sent as an oscillation frequency command signal from the firing number calculation circuit 28G to the pulse oscillation circuit 28F.

In the above configuration, for example, when the "80" selection switch _25C is selected, 20 pulses (80 pulses/
An oscillation frequency command signal having a content corresponding to a firing speed of [minutes] is sent out. However, when an acceleration command arrives from the acceleration switch 26 at time _t1 , the firing number calculation circuit 28G generates an oscillation frequency containing 40 pulses (corresponding to a firing rate of 160 pulses/min) for the next time slot. A command signal is sent. Therefore, the launcher 1 substantially achieves the specified firing rate of 80 in the time slot between points _t2 and _t3 .
Balls can be fired at twice the firing speed of [balls/min].

If the acceleration switch 26 is kept pressed here,
The specified firing rate is 80 pieces/minute until time t ₄ after the elapse of 4 times the time slot (i.e. 1 minute).
, but again in the time slot between points t ₄ and _{t 5} .
The firing rate reaches a rate of 160 pieces/minute. Thus, no more than 100 balls are fired in any one minute period.

In the above embodiment, a case was explained in which the firing device 1 having the rotary solenoid 1A as a driving source was used, but instead of this, the sixth
A configuration having an electric motor 41A as shown in the figure may also be used. In this case, the output shaft of the electric motor 41A is brought into sliding contact with the roller 41D fixed to the firing rod 3 via the reduction output gear 41B, and the firing rod 3 is rotated against the return spring 41E every half rotation of the cam 41C. After the movement, by suddenly removing the roller 41D from the cam 41C, the firing rod 3 is activated by the return spring 41E. Here, the return spring 41E is coupled to a take-up pulley 41G fixed to the operation dial 2 via a wire 41F, and by operating the operation dial 2 to wind up or unwind the wire 41F around the take-up pulley 41G. The resilient force applied to the firing rod 3 from the return spring 41E can be adjusted.

When using the launcher 1 having such a configuration, the drive output unit 28E in FIG. 3 serves as the launch number control device 28.
, "100" to "70" selection switch 25A to 25D
The configuration may be changed to such that the drive power supply voltage applied to the electric motor 41A is controlled by the output of the accelerator switch 26 and the output of the acceleration switch 26, thereby controlling the rotational speed of the electric motor 41A.

Although the firing number selector 25 is of a multi-stage type in the above embodiment, it may be of an unauthorized type.

<Effects of the Invention> As explained above, according to the present invention, while complying with the maximum total number of batted balls (for example, 100) that can be fired within a predetermined period of time (for example, 1 minute),
The player's desire to play quickly can be substantially satisfied. In other words, during the game, the player arbitrarily operates the acceleration switch to rapidly increase the number of shots within a unit time that occupies a part of the above-mentioned predetermined time, resulting in a change in which the winning rate is high. It becomes possible to win many batted balls into a prize winning device in a short time. In addition, players can obtain opportunities to demonstrate their gaming skills while considering the timing of operating the acceleration switch, so by actively utilizing the acceleration switch, they can increase the profits they receive. Instead, it is possible to provide an interesting pachinko machine that allows you to enjoy the game in a new way.
