Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bullet-powered gaming machine for playing a game using a game ball.

(Prior Art) A conventional ballistic game machine (for example, an arrangement ball machine or a pachinko machine) generally has a cover that can be opened and closed on all or a part of the front side of the game machine. ing. If the cover is opened by the player during the game, there is a possibility that an illegal game is played. Therefore, a detection switch for detecting the opening of the cover is usually provided.

On the other hand, in some types of bullet-powered gaming machines, it may be necessary to count the number of gaming machines fired. Specifically, in the arrangement ball machine, the number of shooting balls that can be used in one game is limited to a predetermined number (for example, 16). Therefore, in order to count the number of gaming machines fired from the shooting device, a detection switch for detecting the passage of the shooting ball is separately provided.

(Problems to be Solved by the Invention) In the conventional bullet-operated gaming machine, a detection switch for detecting the opening of the cover and a detection switch for detecting the passage of the shooting ball are provided separately. Therefore, not only the detection switches but also cables and the like for transmitting signals output from these detection switches to a control unit provided in the game machine main body are required, resulting in an increase in cost. In addition, installation of detection switches and cable routing must be performed for each detection switch. Therefore, the working time in the manufacturing process of the bullet-powered gaming machine has been long.

The present invention has been made in view of such a point,
It is an object of the present invention to provide a bullet-operated gaming machine in which the number of detection switches is reduced, the production cost is reduced, and the operation time in the production process is reduced.

(Means for Solving the Problems) The present invention detects the opening of a cover in an elastic game machine having a cover that can be opened and closed on all or a part of the front side of the game machine. And a detection switch for detecting the passage of a shooting sphere fired by the shooting device is provided.

(Operation) According to the present invention, the detection switch detects the opening of the cover and also detects the passage of a shooting sphere fired by the firing device. Since this detection switch plays a role of performing two detections, only one detection switch is required. As a result, costs can be reduced and
The working time in the manufacturing process can be reduced.

The firing motor drive circuit 14 of the firing device control board 13 will be described with reference to FIG.
Is a power supply circuit 14a, a touch input circuit 14b, and an oscillation circuit 14c.
And a pulse motor output circuit 14d.

In the power supply circuit 14a, 24V AC is connected to the power supply terminals CN1 No. 1 and 2, the power supply terminal CN1 No. 2 is connected to the power supply terminal CN2 No. 1, and the firing motor drive is connected to the CN2 No. 1 and No. 2. circuit
A relay for a firing motor that opens and closes the relay 14 is connected, and by turning ON / OFF the relay for the firing motor, a power supply circuit 14 is connected.
a is opened and closed. The rectified wave, which is full-wave rectified through the bridge rectifier DP1 of the power supply circuit 14a, is smoothed by the electrolytic capacitor C2, becomes a DC power supply line of the firing motor 9, and includes resistors R1, R2, R25 to R30, and a diode ZD1. The capacitor C1 forms a 12V DC power line.

The touch input circuit 14b is configured to pick up and amplify a hum noise of 50-60 Hz flowing through the human body, and output a touch signal when the player touches the steering wheel 15. The touch input terminal CN4 is connected to the handle 15, and the hum noise input from the touch input terminal CN4 is amplified by the transistors Q9 and Q10 and then input to the first IC1. Therefore, when the human body touches the touch input terminal CN4, the potentials of the first and second terminals of CN4 decrease, and the transistor Q1
0 collector voltage is the threshold voltage of IC10 (about 6
When the voltage drops below V), the number of IC1 becomes H, and the capacitor C6 is charged via the diode DA7 and the resistor R17. IC1
If the time when the second is high is about 1.5 ms or more, I
No. 3 of C1 exceeds the threshold voltage, No. 4 of IC1 becomes L, No. 8 of IC1 becomes H, and a touch signal is output. If the collector voltage of the transistor Q10 exceeds 6V, it is regarded that there is no touch input, and the number of the IC1 becomes L, so that the electric charge of the capacitor 6 is discharged through the resistor R18. When the second of IC1 becomes L for about 280ms,
No. 4 of IC1 becomes H, and No. 8 of IC1 becomes L, and no touch signal is output. The touch sensitivity can be adjusted by changing the bypass current at the base of the transistor Q10 by the variable resistor VR1.

00 = 99.91 RPM. By changing the oscillation frequency of the crystal oscillator X1, the rotation speed of the firing motor 12 can be changed. Assuming that the accuracy of the crystal oscillator X1 is 500 RPM, the rotational speed error of the firing motor 12 can be kept within the range of ± 0.05 RPM. Resistor R19 and capacitor C5 are I
Reset IC4 via No. 6 of C3 and IC2 via No. 9 of IC3
Is connected to No. 6 of IC3 in order to reset. Since No. 8 of IC1 of the touch input circuit 12b is connected to No. 1 of IC3, when there is no touch input, IC2 is in a reset state.

In the pulse motor output circuit 14d, 3 of IC2 of the oscillation circuit 14c
The clock signal supplied from the number 2 drives the firing motor 12 to rotate by the two JK flip-flops of the IC4.

One of the inputs 6, 8, 1, 1, and 13 of each gate is connected to 8 of IC1 of the touch input circuit 14b. Only when there is a signal, a signal is output from outputs 3, 4, 10, and 11 of IC5, and this signal is input to the bases of transistors Q5 to Q8 via resistors R20 to R23. Launch motor 12
Has two windings, one of which is connected to the second and fourth output terminals CN3, and the other being connected to the first and third output terminals CN3, respectively. No. 15 of IC4 is H, I
If C4 No. 14 is L, IC5 No. 4 is L and IC5 10
Is H, and as a result, the transistors Q6 and Q1 are turned on, so that the output terminal CN3 No. 1 is + and the output terminal CN3 is-, and the firing motor 12 is fixed to the output terminals CN3 No. 1 and No. 3. Voltages of opposite polarity as excitation signals for high-speed rotation are alternately output. Similarly, voltages of opposite polarity as excitation signals are alternately output to the second and fourth output terminals CN3.

It is deemed to have entered the No. 4 16-ball entrance 62, 3, 7, 10,
The No. 14 ball entry display LED 65 lights up all at once according to a command from the central control board 5. However, if the game ball does not fall into the second central entrance 79 during the current game, the open state of the second central entrance 79 is carried over to the next and subsequent games.

When the game ball passes through the inside of the second passage opening 87 of the display stop switch 86, the second symbol display 69 stops the variable display by the detection signal of the display stop switch 86. When the display number when the second symbol display body 69 stops the variable display becomes 3 or 7, the upper solenoid 71 operates by the command of the central control board 5, and the upper tulip bodies 72 move outward respectively. It swings and the first central ball entrance 73 is opened for 1.5 seconds.

While the first central entrance 73 is open, the game ball is the first central entrance.
When the ball falls into 73, the second ball detection switch 81 detects the ball and a detection signal is input to the central control board 5,
1.5 hours from the start of opening of the first central entrance 73
Even within seconds, the upper solenoid 71 returns at that time, and both upper tulip bodies 72 swing in the approaching direction.
The central entrance 73 is closed, and it is considered that the ball has entered the 16 consecutive entrances 62 of Nos. 7 and 10, and the 7th and 10th entrance display LEDs 65 are commanded by the central control board 5, respectively. Lights up, and the winning score established up to that point is doubled. In addition, reopening of the first central entrance 73 during the current game is prohibited.

16 effective launching spheres with 16 consecutive entry ports 62, 1st central entry port 7
3. If the ball falls into one of the second central entrances 79 and each of the entrance detection switches 63, 75, 81 detects the entrance, the entrance entrance and the entrance entrance considered to be entered And the number information of the lit ball display LED 65 is input to the central control board 5, and it is determined whether or not a prize has been won based on the number information.
At the time of winning, the winning score is stored and displayed by the score display LED 88 on the game board 2a. Further, when the winning is established, the prize ball payout motor 43 is driven to rotate in accordance with the winning score, and the prize ball corresponding to the winning score is paid out to the player.

The winning score is determined when the combination of the four consecutive numbers shown in the following table is established, that is, four consecutive numbers of the ball display LE
When D65 is lit, one point is given for each combination, and a prize ball is paid out each time a winning is established.

However, the highest score is 10 points, and if the winning score exceeds 10 points, 11 or more points are discarded and A is displayed on the score display LED 88.

In each game, when 16 game balls are fired,
A firing sphere is detected by the firing sphere detection sensor 22 at each firing, and a return sphere is detected by the return sphere detection switch 26, and the entry of each effective firing sphere into each of the entrances 62, 73, and 79 is detected. Detected by each incoming ball detection switch 63, 75, 81,
The incoming ball detection signal is input to the central control board 5.

Then, when 16 effective firing balls are fired and the firing ball detection sensor 22 detects the 16th, that is, the firing of the final effective firing ball, the firing motor relay is turned off and 1
When the launch of the sixth or later game ball is prohibited, and then the entry of the 16th effective launch ball is detected by any of the entry detection switches 63, 75, 81, the game of that time ends, 0.
After 5 seconds, the firing motor relay is turned on again, and the next game can be started. When the 16th effective launch ball becomes a return ball, the firing motor relay once turned off is turned on again by the detection signal of the return ball detection switch 26, and one additional game ball is supplied and added. The game ball that has been fired becomes the 16th effective fire ball, and the current game is ended when this game ball is detected as entering.

In addition, as shown in FIG. 16, if the entry of the 16th effective firing ball is not detected even after 5 seconds from the detection of the launch of the 16th effective firing ball, the 16th effective firing ball is detected. When the game start switch 25 is pressed during the effective period after 5 seconds have passed since the detection of the effective launch ball, the relay for the launch motor is turned on, the current game is settled, and the next game is started. It is set so that, for example, when the game ball is caught by a nail or the like on the game board surface 2a and stopped and the number of incoming balls becomes less than 16, the number of incoming balls becomes less than the effective number of launched balls It is possible to deal with the shortage of incoming balls.

Further, as shown in FIG. 13, within a certain period of time after the game is started, for example, the entry of the 16th effective firing ball is detected, the relay for the firing motor is turned ON, and the next game can be started. Within one second from the point when the game has become, the detection of the ball entry by each of the ball entry detection switches 63, 75, and 81 is prohibited, and the next game will be executed only after one second has passed since the point at which the game was started. Is set so as to detect the entry of the first effective firing sphere at, so that, for example, when a game ball is provided extra to the player (service sphere), an extra shot is performed. It is possible to cope with a violation in which the firing ball is invalidated and 16 or more valid firing balls are fired. In addition, the start time to prohibit the ball detection is the time when the first launch ball is detected, the time when the launch motor 12 is stopped,
The time at which the 16th effective firing sphere is counted may be set as a reference.

When the entry of the 16th effective launch ball is detected, the launch motor relay is normally turned on and the next game can be started, but at this point the prize ball payout prohibition switch 45 is
When it is ON, that is, when the game balls are filled in the lower ball receiving tray 8, the relay for the firing motor is turned ON until the prize ball payout prohibition switch 45 is turned OFF as shown in FIG. It is set so that it does not become.

Next, the operation and effect of the embodiment having the above configuration will be described.

In this example, a firing motor 12 that is rotationally driven to fire a specified number of game balls at a fixed firing interval, a power supply circuit 14a that converts AC to DC, and a pulse motor that outputs an excitation signal that rotates the firing motor 12 A launching motor drive circuit 14 having an output circuit 14d, and when the launch of the last game ball in one game is detected, the launching motor drive circuit 14 is opened based on the detection signal to stop the launching motor 12 And control means for causing the control to be performed.

For this reason, the number of game balls that can be fired in each game is determined, the number of game balls used in each game is easily set, and the supply of the specified number or more game balls to the firing position is restricted. The cutting mechanism becomes unnecessary, and the ball feeding mechanism for sending the game balls to the firing position can be simplified.

Further, since the oscillation motor 14c and the pulse motor output circuit 14d are provided in the firing motor drive circuit 14 for controlling the rotation of the firing motor 12, the output rotation speed of the firing motor 12 can be easily changed, and A gear mechanism for changing the firing interval is not required, and a power supply circuit 14a for converting alternating current to direct current is provided, so that different electric components are used for different regions with different power supply frequencies or different devices are assembled. This eliminates the need for trouble and can increase the versatility of the launch control device.

In this example, the number of game balls used in one game,
Since the number of prize balls to be paid out to the player per one prize score is matched, the occurrence of extra balls or insufficient balls in the game can be prevented.

Also, since the winning points that have been won are stored and the prize balls corresponding to the winning points are paid out, even if a plurality of winnings are made at the same time, the prize balls can be smoothly and promptly paid out to the player. Can be.

Further, in this example, if the launch ball is not detected even after 5 seconds from the detection of the launch of the 16th effective launch ball, if the game start switch 25 is pressed during the effective period after the lapse of 5 seconds, It is set so that the current game is over and the next game can be started, and from the time when the entry of the 16th effective firing ball is detected and the next game can be started Since it is set to detect the first valid launcher in the next game only after one second has elapsed, the number of valid launches will be greater than the number of incoming launches, It is possible to cope with excess or deficiency of the number of incoming balls when the number of balls becomes larger than the number of balls.

The relationship between the above embodiment and the present invention is as follows. That is, in the detection switches (the launching ball light emitting diode 21 and the launching ball detection sensor 22), the detection switch has a role of performing two detections. More specifically, as the first role, it detects the passage of a shooting sphere fired by a firing device (a firing control device K1). By this detection, the number of fired balls actually fired can be counted. As a second role, it detects whether or not the cover (front plate 4) has been opened. By this detection, an illegal game can be prevented. Thus, only one detection switch that fulfills two roles is required, so there is no need to install another detection switch or the like and route a cable or the like. Therefore, the cost can be suppressed, and the working time in the manufacturing process can be reduced. The detection switch is used not only for opening the front plate 4 but also for a cover such as the metal frame 3 or the main body frame 1 which can be opened and closed on all or a part of the front side of the gaming machine. Similarly, the opening can be detected.

The detection switch outputs a signal (front plate open detection signal) indicating that the cover (front plate 4) has been opened when a certain condition (continuation of the detection state for a certain period of time or more) is satisfied. Under the conditions, a signal indicating that the passage of the shooting sphere has been detected (a shooting sphere detection signal) is output. Therefore, even when only one detection switch is provided, the state can be clearly grasped by the bullet-starting game machine by the signals of the types corresponding to the respective roles. In particular, a signal output when a certain condition is satisfied makes it clear that a fraudulent game has been played, and makes it easier to take subsequent measures.

Further, the detection switch can detect the opening of the cover and the passage of the shooting sphere fired by the shooting device in a non-contact state. Therefore, since there is no abrasion or the like unlike a mechanical detection switch, there are few failures, and the switch can be used for a long period of time. As the detection switch, not only an optical switch including the launching ball light emitting diode 21 and the launching ball detection sensor 22, but also a magnetic switch that detects opening of the cover by a change in the magnetic field may be used.

As described above, the embodiment of the present invention has been described. This embodiment has aspects of the invention other than the aspects of the invention described in the claims. Embodiments of the present invention will be enumerated below, and related explanations will be provided as necessary.
