Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sound effect generating device for a game machine, and in particular to a sound effect generating device for a game machine in which a game is played by firing pachinko balls onto a game board. The present invention relates to a sound effect generating device for a gaming machine that generates sound effects.

[Prior art] Generally, pachinko gaming machines and metal gaming machines (commonly known as arrangement balls) play games by hitting pachinko balls.
Pinball game machines such as the following are in practical use. As is well known, pinball game machines use an electric ball hitting mechanism and a manual ball hitting mechanism as mechanisms for firing pachinko balls onto the game board. This electric ball hitting mechanism rotatably supports the ball hitting rod that hits the pachinko balls that have been guided to the ball hitting position, and is connected to a motor and the rotating shaft of the motor in order to rotate the ball hitting rod using electric power. The ball-hitting cam is provided with a ball-hitting cam, and the ball-hitting rod is intermittently rotated by the rotation of the ball-hitting cam. Then, in order to apply elastic force to the ball-striking rod, one end of a ball-striking spring is connected to the ball-striking rod, one end of a wire is connected to the other end of the ball-striking spring, and the other end of the wire is directed toward the ball-striking direction. Wrap it around a pulley in a tensioned state and guide it toward the batting rod. Further, an adjustment ring for adjusting the hitting force is provided at the lower front of the pinball game machine, and the rotation axis of the adjustment ring is guided to the back side and fixed to the pulley. Connect the other end of the wire to this pulley. By rotating the adjustment ring, the pulling state of the wire is varied, the elastic force of the ball hitting spring is varied, and the ball hitting force is adjusted. In addition, in the manual ball hitting mechanism, a ball hitting lever is rotatably provided at the lower front of the pinball game machine, the rotation axis of the ball hitting lever is connected to the rotation axis of a ball hitting rod, and a ball hitting spring is attached to the ball hitting rod. One end is connected, and the other end of the ball hitting spring is engaged with a part of the game machine main body.

[Problems to be Solved by the Invention] By the way, in the conventional electric ball hitting mechanism as described above, while the adjustment ring is rotated to adjust the hitting strength, the hitting rod is intermittently moved by the ball hitting cam. The state in which the pachinko ball is rotated and hit is transmitted as vibration to the player's hand via the ball hitting spring and wire. Therefore, each time a player hits a pachinko ball, he or she can visually recognize the pachinko ball guided through the ball guide rail along with the vibrations caused by the intermittent rotation of the batting rod. On the other hand, in the manual ball hitting mechanism as well, each time the player rotates the ball hitting lever, the ball hitting rod is rotated to shoot pachinko balls. In this way, when hitting a ball with a conventional electric ball hitting mechanism or a manual ball hitting mechanism, the hitting state of the pachinko ball is determined by the tactile sensation from the player's finger hitting operation and the visual sense from seeing the pachinko ball actually fired. It is then recognized. However, since players usually stare at the vicinity of the ceiling hole formed at the top of the game board, they rarely see the pachinko balls fired from the ball guide rail. Therefore, if it were possible to generate a sound effect representing the hitting state in relation to the hitting of a pachinko ball, the player would be able to auditorily recognize the hitting state through the sound, and the fun of the ball hitting game would also be improved.

Therefore, it is an object of the present invention to provide a sound effect generating device for a game machine that can generate a sound effect to notify the ball firing state in connection with firing pachinko balls to a game board.

[Means for Solving the Problems] A sound effect generating device for a gaming machine according to the present invention includes: a manual operating means for operating a ball firing mechanism; ball launch detection means for detecting that the pachinko balls have been driven or that the pachinko balls have been launched toward the game board by driving the ball launch mechanism; and a ball launch detection means that notifies the launch status of the pachinko balls every time there is an output from the ball launch detection means. It is characterized by comprising a sound generating means for generating sound.

[Operation] Pachinko balls can be fired onto the game board by driving and operating the ball firing mechanism through the manual operation means. Then, the ball firing detection means detects that the ball firing mechanism has been driven, or that pachinko balls have been fired toward the game board by driving the ball firing mechanism. Further, the sound generating means generates a sound to notify the firing state of the pachinko balls every time there is an output from the ball firing detecting means.

That is, when pachinko balls are fired onto the game board, the player is aurally informed of the ball firing state through sound effects.

[Embodiments of the Invention] Examples of the invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a sound effect generator according to an embodiment of the present invention. In the configuration, the sound effect generating device of this embodiment basically includes a ball launch detection means 11 that detects a phenomenon in which a ball is launched toward the game board.
and sound source means 10 which includes a monostable multi 12, a gate circuit 13, a sound source signal oscillation circuit 14, and an amplifier circuit 15 and which derives a sound source signal according to the output of the ball launch detection means 11, and which generates the sound source signal as sound. It is composed of a speaker 40, which is an example of a sounding means.
This sound source means 10 and the speaker 40 constitute a sound generating means.

FIG. 2 is a perspective view of an example of a ball hitting mechanism to which the sound effect generating device of the present invention is applied. In particular, a ball firing detection means 11 is positioned at a position where the rotational state of the ball hitting rod can be detected.
This shows the case where .

3A and 3B are illustrative diagrams showing the operating state of the ball-hitting mechanism 20 shown in FIG. 2; in particular, for example, FIG. 3A shows the state where the ball-hitting operation is stopped, and FIG. 3B shows the ball-hitting operation state. .

The configuration of the ball hitting mechanism 20 will be explained with reference to FIGS. 2 to 3B. The front panel (not shown) of the pinball game machine is manually operated by the player to display the hitting strength of the pachinko ball. An adjustment ring 21, which is an example of a manual operation means for adjustment, is provided, and a ball hitting switch (not shown) is provided to issue a ball hitting command by pressing the adjustment ring 21, and to adjust the ball hitting speed as necessary. A ball speed adjustment knob (not shown) is provided. For example, the following mechanism can be considered as a mechanism for adjusting the ball speed. In other words, the ball speed adjustment knob and the resistance adjustment slider of the variable resistor are linked, and the variable resistor changes the resistance value by rotating the ball speed adjustment knob and is based on the resistance value. The circuit is configured to provide a variable voltage value to the gate signal generation circuit. The gate signal generation circuit generates a gate signal so as to achieve a batted ball speed determined by the operation of the batted ball speed adjusting knob, and supplies the gate signal to the tipper control circuit. When the ball hitting switch is closed, the chopping control circuit chippingly controls the output voltage of a separately provided power supply based on a gate signal, and controls the motor 28 (see Fig. 2) which is the drive source for hitting the pachinko balls. The circuit is configured to vary the rotational speed of the motor 28 by variably controlling the voltage supplied to the motor 28, thereby varying the speed at which the ball is hit by the ball hitting rod 25 (see FIG. 2).

In addition, in a part corresponding to the adjustment ring 21 on the back side of the pinball game machine, there is a gear 221 that is rotated by the rotation of the ball hitting ring 21, and a gear 221 that meshes with the gear 221 and a gear 223 that rotates the adjustment ring 21. A gear 222 is provided for transmitting. This gear 222 has a wire 2 which is rotated by the rotation of the adjustment ring 21.
A fan-shaped wire winding member 2 connected to one end of 31
32 is fixed. This wire 231 is attached to the pulley 2
connected to one end of the ball striking spring 24 via 33;
It is held slidably by a wire receiving member 234. The other end of the ball-striking spring 24 is connected to a ball-striking rod 25 . The ball hitting rod 25 is rotatably supported by a support shaft 251, and has a rod portion 252 formed at its tip for hitting pachinko balls that are successively guided to the launch point rail 26. A lever 253 is fixed to a portion of the ball hitting rod 25 supported by the support shaft 251, and a pin 254 is fixed to the tip of the lever 253. Further, a shielding plate 256 is fixed to the other end (lower side in the figure) 255 of the ball hitting rod 25 . A stopper 27 is provided corresponding to the other end 255 of the ball batting rod 25 to engage with the other end 255 and stop the ball batting rod 25 so that the ball batting rod 25 is at a predetermined stopping position. . Further, in relation to the lever 253, the motor 2 as an electric motor
A ball hitting cam 29 that is intermittently rotated at a constant angle by the rotational force of 8 is disposed at a position where it can engage with the pin 254. This motor 28 is a geared motor having a built-in gear for changing the rotational speed, and is constructed by fixing a ball hitting cam 29 to a gear shaft at the final stage that has been changed in speed. The arc-shaped protrusion of the ball-hitting cam 29 (the illustration shows a case of three blade-like cams provided every 120 degrees) and the tip of the lever 253 fixed to the ball-striking rod 25 The ball-hitting cam 29 contacts the pin 254, and as the ball-hitting cam 29 rotates, the arcuate protrusion of the ball-hitting cam 29 hits the pin 2.
When the ball hitting rod 25 is rotated by a certain angle by pressing the ball hitting cam 29 and the pin 254
When the contact state with the ball is released, the ball hitting rod 25 is pulled by the tension of the ball hitting spring 24, thereby hitting the pachinko ball guided to the ball hitting position on the firing rail 26.

On both sides of the shielding plate 256, photoelectric sensors 11A, which are an example of ball launch detection means, are provided to detect when the batting rod 25 is stopped at a predetermined stop position. This photoelectric sensor 11A is a light projector 11
1 and a light receiving section 112, and detects a predetermined position depending on the state in which the light emitted from the light projecting section 111 is blocked by a shielding plate 256.

Note that instead of the photoelectric sensor 11A, a photocoupler in which a light emitting diode and cadmium sulfide (hereinafter referred to as Cds) are integrally provided may be used. Further, as another example of the ball launch detection means, a reed switch may be used in which a magnet is fixed to the shielding plate 256 and a detection output is derived by the proximity of the magnet.
The shielding plate 256 may be made of a metallic material, and a proximity switch may be used as the ball launch detection means, which derives an output based on the proximity of metal.

FIG. 4 is an illustrative view of an example of a state in which a speaker 40, which is an example of the sound generating means, is attached. In the figure, a surplus ball tray 42 is provided below the front frame 41 of the pinball game machine to receive surplus balls when the balls stored in the ball tray connected to the ball waiting gutter overflow.
A surplus ball dispensing port 43 is provided in the part connected to the surplus ball receiving tray 42.
is formed. This surplus ball dispensing port 43 is a path 44
and 45 to the prize ball payout port. A plurality of sound holes 461 are bored in the rear plate 46 of this path 45.
A speaker 40 is attached to the rear of the speaker 1 with a mounting member 462. Note that as another example of the sound generating means, a piezoelectric element may be used instead of the speaker 40.

Next, with reference to FIGS. 1 to 4, a specific operation of an embodiment of the present invention will be described.

When the player rotates the adjustment ring 21 to adjust the strength of the ball hit and presses the ball hit switch,
Power is supplied to the motor 28 through the ball hitting switch, and the motor 28 is continuously driven to rotate. Since the ball hitting cam 29 is rotationally driven in conjunction with the rotational drive of the motor 28, the ball hitting cam 29 is rotated by the ball hitting rod 25.
By pushing down the engagement pin 254 formed in the arcuate portion in the direction of arrow x1, the ball hitting rod 2
5 in the direction of arrow x2. At this time, as the batting rod 25 moves, the shielding plate 256 rotates in the x3 direction and is pulled out from the position of the photoelectric sensor 11A, so the photoelectric sensor 11A derives a high level (hereinafter referred to as "H") signal. . This "H" signal is given to the monostable multi 12. This monostable multi-12
is from the fall of the photoelectric sensor 11 output to the batting rod 2.
By configuring the circuit to derive the "H" signal for a period shorter than the one-time ball batting period (for example, only 1/2 or less of the ball batting period), the "H" signal is not derived yet.

Then, the arcuate portion of the ball hitting cam 29 and the engagement pin 2
54, the ball hitting rod 25 rotates in the direction opposite to the arrow x2 by the tensile force of the ball hitting spring 24 and hits a pachinko ball. At this time, at the same time as the batting rod 25 hits the pachinko ball at the batting position, the shielding plate 256 blocks the optical axis of the photoelectric sensor 11A, so the output of the photoelectric sensor 11A falls to an "L" signal. In response, the monostable multi 12 derives an "H" signal for a certain period of time and supplies it to the gate circuit 13. This gate circuit 13 is connected to the output of a sound source signal oscillation circuit 14 that oscillates a signal that becomes the sound source of a sound having a frequency and waveform (i.e. tone) suitable for the hitting sound (or hitting sound) of a pachinko ball. is always given. Therefore, the gate circuit 13 derives the sound source signal of the sound source signal oscillation circuit 14 for a certain period of time and supplies it to the amplifier circuit 15. Amplifier circuit 1
5 amplifies the sound source signal and generates it from the speaker 40 as a hitting sound. Preferably, the degree of amplification of the amplifier circuit 15 can be variably set using a variable resistor 151, so that the volume can be variably set between daytime and nighttime.

Thereafter, in the same manner, each time the ball hitting rod 25 is pulled by the rotation of the ball hitting cam 29 and then returns to the ball hitting position, the photoelectric sensor 11A derives a pulse output, and at the falling edge of the pulse (that is, the shielding plate A hitting sound indicating that one pachinko ball has been hit is generated for a certain period of time from when the ball interrupts the optical axis), thereby generating a hitting sound for each hit ball.

According to the embodiment described above, there is an advantage that the ball hitting state can be notified by sound in conjunction with the ball hitting operation of the ball batting rod 25.

In addition, as another embodiment of FIG. 1, the amplifier circuit 1
5 is a voltage controlled amplifier circuit, and a waveform shaping circuit is provided which generates a waveform that has a steep peak value when the output pulse of the monostable multi 12 rises and gradually attenuates when it falls. By varying the degree of amplification of the voltage-controlled amplifier circuit with the output of , the sound may be made more suitable for the hitting sound.

By the way, in the above embodiment, as an example of detecting the firing state of the pachinko ball, the rotational state of the batting rod 25 is detected, but the ball firing state may also be detected based on other states. good.

FIG. 5 is an illustrative view showing another example of the ball launch detection means, and particularly shows a case where the ball launch state is detected based on the operating state of the ball supply member. In the configuration,
The end of the ball waiting gutter (not shown) provided at the lower front of the pinball game machine is connected to the entrance 51 of the ball supply gutter 51.
1. At the end of this ball supply gutter 51, a through hole 512 is bored in its bottom surface, and a ball supply outlet 513 is formed in its back surface. A firing point rail 26 is formed below the back side of this ball supply outlet 513. Further, below the through hole 512, a ball supply member 52 is provided so as to be swingable about a fulcrum 521. This ball supply member 52 has a ball pushing piece 522 protruding upward in a portion located directly below the through hole 512, and a long hole 522 at the tip of one side of the ball pushing up piece 522.
23, and a permanent magnet 524 that also serves as an overlap is fixed to the tip of the other side. The long hole 523 has an L
A protrusion 5 formed on the short side of the indicating engagement lever 53
31 is inserted. The long side of this lever 53 is engaged with a pin 54 fixed to the ball hitting rod 25.
This allows the ball supply member 52 to swing freely in conjunction with the rotation of the ball hitting rod 25. On the other hand, a stopper piece 551 that regulates the rotation angle of the ball supply member 52 is formed on the mounting member 55 that swingably supports the ball supply member 52 and fixes the ball supply path 51. A reed switch 11B of another example of the ball ejection detection means 11 is fixed to the upper part of the forming position, that is, the part facing the position where the permanent magnet 524 of the ball supply member 52 is rotated most clockwise. It should be noted that other parts of the configuration that are the same as those in FIG. 2 are designated by the same reference numerals, and explanations thereof will be omitted.

In operation, when the ball hitting cam 29 rotates to rotate the ball hitting rod 25 in the y1 direction, the pin 54 engages with the lever 53 and moves the lever 53 in the y1 direction.
By rotating in two directions, the lever 53 rotates the ball supply member 52 in the y3 direction. As a result, as shown by the two-dot chain line, the ball hitting rod 25 is in a tensioned state and the ball pushing piece 522 of the ball supplying member 52 is pulled out from the through hole 512. When the ball hitting cam 29 further rotates and the engagement between the arcuate portion of the ball hitting cam 29 and the pin 254 is disengaged, the ball hitting rod 25 is pulled by the elastic force of the ball hitting spring 24 in a direction opposite to the y1 direction. is rotated to As a result, the ball hitting rod 25 hits the pachinko balls that have been supplied to the ball hitting position in advance. The hit pachinko balls are driven into the game board via the launch point rail 26 and a guide rail (not shown) provided to guide the balls from the end of the launch point rail 26 to the upper part of the game board. Simultaneously with the ball hitting operation of the ball hitting rod 25, the ball supplying member 52 rotates in the direction opposite to the y3 direction, and the ball pushing piece 522 pushes up the pachinko balls waiting on the through hole 512, thereby pushing up the pachinko balls. is supplied to the ball hitting position of the launch point rail 26 via the ball supply outlet 513. This state is shown by a solid line.
At the same time, as the ball supply member 52 rotates, the reed switch 11B detects the proximity of the permanent magnet 524 and outputs an "H" signal. reed switch 11
The "H" signal output of B is given to the monostable multi 12 shown in FIG. In this case, monostable multi 12
The switch uses an "H" signal for a certain period of time after the rise of the "H" signal output from the reed switch 11B, and its output is applied to the gate circuit 13. Therefore, in conjunction with the ball supplying operation of the ball supplying member 52, a sound effect representing the ball hitting state is generated in the same manner as the operation explained in FIG. 1 above.

Thereafter, in the same manner, each time the ball-striking rod 25 rotates and hits one pachinko ball one after another, the ball supplying member 52 swings in conjunction with the rotation of the ball-striking rod 25 to perform a ball-supplying operation. Based on the swinging state of the ball supply member 52, a sound effect representing the ball hitting state is generated. That is,
The reed switch 11B can detect the movement of the ball hitting rod 25 via the ball supply member 52.

FIG. 6 is an illustrative view of still another embodiment of the ball launch detecting means, and particularly shows a case where a proximity switch 11C is provided in connection with a launch ball guide rail such as the launch point rail 26 or the guide rail 26'. In the figure, the launching point rail 26 is bent into an L-shape so that the starting end is the ball-striking position where the pachinko ball waits, and the punch portion 252 of the batting rod 25 is inserted into the L-shaped bent portion. An insertable through hole is formed, the end of which is inclined upward, and the end thereof is bent downward. A proximity switch 11C, which is another example of ball launch detection means, is provided above the terminal end of the launch point rail 26 from the ball hitting position. In the extending direction of the end of the firing point rail 26, the firing point rail 26
A guide rail 26' is provided which guides the pachinko balls launched along the top of the game board. The launch point rail 26 and the guide rail constitute a connecting ball guide rail. Then, the proximity sensor 11C detects pachinko balls passing on the launch point rail 26. In addition, as another arrangement position of the proximity sensor 11C, it may be provided on the guide rail 26' side. Also,
A photoelectric sensor, a reed switch, or the like may be used instead of the proximity sensor.

In the above description, the ball launching mechanism to which the sound effect generating device of the present invention is applied is an electric ball striking mechanism or a manual ball striking mechanism, but the present invention also applies to other ball launching devices. can apply the technical ideas of

As explained above, the ball firing detection means 11 has various configurations, and the ball firing mechanism is driven in response to the operation of the manual operation means, or
Any device may be used as long as it detects that pachinko balls are ejected toward the game board by driving the ball ejecting mechanism.

FIG. 7 is an illustrative view showing another example of the ball firing mechanism. This ball firing mechanism 70 sequentially lines up one pachinko ball stored in a ball waiting gutter (not shown) provided at the front of the gaming machine and guides it to a lift 71. The lift 71 has ball receiving parts 712 formed at regular intervals on the belt 711, and pulleys at the upper and lower parts of the gaming machine (only the upper pulley 713 is shown in the figure).
A belt 711 is hooked to the pulley, and an upper pulley 713 is rotationally driven by a motor 714.
A path 72 and a path 73 are provided at the top of the lift 71 to guide the pachinko balls lifted by the lift 71 to the center of the game board. This path 73 has a lower end on the path 72 side as a fulcrum 731, and its tip is configured to be rotatable. The tip of this path 73 is the rotary firing member 7
4. This rotating firing member 74 has a cylindrical shape with an inner diameter larger than the diameter of a pachinko ball, and a gear 75a is fixed to the back side of the rotating firing member 74.

a and a gear 75b are rotatably supported by a shaft 752. Then, a portion of the semicircular pulley 76a and a protrusion formed on the game board surface are tension-biased by a spring 77. One end of a wire 78 is fixed to one end of the semicircular pulley 76a, and the wire 78 is hung along the outer circumferential groove of the semicircular pulley 76a and can be freely rotated by a ball hitting direction control ring provided on the front surface of the game board via the pulley 76b. shall be. By adjusting the rotating direction of the rotating firing member 74, the pachinko balls lifted by the lift 71 are fired in the direction of the rotating firing member 74. In such a ball firing mechanism 70,
Ball shot sensor 1 as an example of the ball shot detection means 11
1D is provided below the path 72 or 73. This shot ball sensor 11D uses, for example, a coil 113 as a detection part, and when a pachinko ball passes, the coil 11
The oscillation operation is performed based on the change in the inductance of No. 3, and the oscillation output is waveform-shaped into a pulse and derived as a pachinko ball detection output. The sound effect generating device of the present invention can also be applied to such a ball firing mechanism, and a sound effect representing a fired ball can be generated every time a pachinko ball is supplied to the rotary firing member 74 via the path 72. can.

In addition, in the above-mentioned embodiment, a case was described in which a sound source means and a sound generating means were used as an example of a sound generating means.
As another sound generating means, an electronic buzzer which generates a sound every time there is an output from the ball launch detecting means may be used.

[Effects of the Invention] As described above, according to the present invention, a sound effect can be generated each time a pachinko ball is fired to inform the player of the ball firing state, and the sound effect can be provided to the player not only visually and tactilely, but also auditorily. Since the ball firing state is notified, the ball firing game can be made more interesting and the game can be played more effectively.

In addition, in order to generate a sound effect every time a pachinko ball is fired, we detect the firing of the pachinko ball itself, which is a condition for generating a sound effect, or the drive of the ball firing mechanism, which is the direct cause of pachinko ball firing, and use the detection output as Since the sound effect is configured to be generated based on the sound effect generation condition, high reliability can be maintained in generating the sound effect by generating the sound effect based on the establishment of a phenomenon that is directly connected to the sound effect generation condition. In other words, compared to the case where, for example, the ball firing mechanism drive control signal input to the ball firing mechanism is branched midway and a sound effect is generated based on the branched drive control signal, due to malfunction etc. It is possible to reduce as much as possible the inconvenient situation where the ball firing mechanism is not operating even though the sound effect is being produced, and the sound effect is generated only when the sound effect generation conditions are definitely met. The reliability of the system can be improved.
