Abstract

PROBLEM TO BE SOLVED: To provide a pachinko game machine provided with a ball hitting device for not generating the failure that a hitting operation is performed even though a human body is not in contact. SOLUTION: When it is judged that a touch sensor 111 is touched in a first flip-flop 120 and it is discriminated that sensitivity is adjusted to be equal to or lower than a prescribed threshold in a second flip-flop 121, hitting operation permission signals are led out from an AND circuit 123. When it is judged that the touch sensor 111 is touched in the first flip-flop 120 and it is discriminated that the sensitivity is adjusted to be higher than the prescribed threshold in the second flip-flop 121, the hitting operation permission signals are not led out from the AND circuit 123. Thus, even when adjustment for raising the sensitivity higher than the prescribed threshold is performed erroneously or intentionally in a game place, since the hitting operation of balls is inhibited, the failure that the hitting operation is performed even though the human body is not in contact is not generated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine having a ball shooting device for hitting a ball with a detection signal from a touch sensor circuit for detecting whether or not a player has touched a contact portion. It is.

[0002]

2. Description of the Related Art Conventionally, a hit ball launching device that hits a hit ball based on a detection signal from a touch sensor circuit that detects whether a player has touched a contact portion has been used to determine whether or not the player has touched the contact portion. A variable resistor for adjusting the detection sensitivity was provided. This variable resistor is configured so that its adjustment range can be adjusted to be extremely large so as to be able to cope with any situation, and the adjustment operation can be easily performed even by a store clerk at a game arcade. Had become. For this reason, in particular, there is a possibility that an adjustment may be performed intentionally or erroneously in a game arcade such that a state in which a bouncing is not possible unless the human body is in contact, but a state in which the bouncing is possible without contact with the human body. .

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems.
It is an object of the present invention to provide a ball game machine provided with a hit ball launching device that does not cause a problem that a bouncing operation is performed even when a human body does not touch.

[0004]

In order to achieve the above object, according to the present invention, a ball is hit by a detection signal from a touch sensor circuit for detecting whether or not a player has touched a contact portion. In a ball game machine equipped with a hit ball launching device, the sensitivity adjustment of a variable resistor that adjusts the detection sensitivity of the touch sensor circuit is adjusted to be higher than a predetermined threshold. The present invention is characterized in that a bouncing operation prohibition control means for prohibiting a bouncing operation is provided. With this configuration, even if the sensitivity is erroneously or intentionally adjusted to increase the sensitivity above a predetermined threshold value in the game arcade, regardless of whether or not there is contact with the contact portion, the hit ball can be hit. Since the launching operation is prohibited, a remarkable effect can be obtained in that the problem that the bouncing operation is performed even when the human body does not contact does not occur.

Further, in the invention according to claim 2, the resilient operation prohibiting control means includes a first flip-flop circuit for determining whether or not the contact portion has been contacted, and the variable resistor being a predetermined resistor. A second flip-flop circuit for determining whether the sensitivity has been adjusted higher than a threshold value, and an AND circuit to which the first flip-flop circuit and the second flip-flop circuit are connected; When the flip-flop circuit determines that the contact portion has been touched, and when the second flip-flop circuit determines that the sensitivity has been adjusted to a predetermined threshold value or less, the AND circuit outputs a pop-up operation permission signal. The first flip-flop circuit determines that the contact portion has been touched, and the sensitivity is adjusted higher than a predetermined threshold value by the second flip-flop circuit. By the fact that to not derive the elastic operation enabling signal from the AND circuit when it is different,
There is an advantage that the resilient operation inhibition control means can be configured with a simple circuit configuration.

According to the third aspect of the present invention, the variable resistor is sealed with a sealing member that cannot be operated unless it is destroyed, so that the detection sensitivity can be properly adjusted at the time of shipment. After shipment, even if an attempt is made to adjust the detection sensitivity that may cause fraud or malfunction, the sealing member must be destroyed. The trace indicates that the sensitivity has been adjusted, so that it is possible to prevent unauthorized sensitivity adjustment after shipment.

Further, in the invention according to claim 4, the sealing member is a sealing cover which covers the variable resistor,
The sealing cover body is fixed by a fixing means that cannot release the sealed state unless it is broken, and has a first fixed portion having a cut portion that is easy to cut, and the cut portion is cut to release the sealed state. And the second fixing portion, which is fixed by fixing means that cannot release the sealed state unless it is destroyed again after being cut, is formed integrally with the second fixing portion, so that the cut portion can be cut even after shipping. The variable resistor can be operated on the playing field side, and then the second fixing portion can be re-sealed by fixing the second fixing portion with the fixing means. Sometimes, an opportunity to adjust the detection sensitivity only once can be provided. In other words, when a situation occurs where the sensitivity has dropped,
At least once, the sensitivity can be increased within an allowable range.

In the invention according to claim 5, the touch sensor circuit is provided with a resistor for determining the threshold value separately from the variable resistor, and the resistor is sealed with a sealing member. By stopping, by changing the resistor used as the reference for setting the threshold value, it is possible to prevent as much as possible the improper operation that causes a problem in which the bouncing operation is performed even though the human body does not touch. .

e (see FIGS. 6 (B) and 6 (C)) are formed with a pair of left and right screw holes 66c, and a fixed saw tooth surface 66d (see FIGS. 6 (B) and 6 (C)) is formed on the inner wall surface. The ratchet cover 66, the end cap 67 formed with the engagement claws 67a (see FIGS. 6A to 6C), the nut 68a,
68b and one-way screws 69a and 69b.

As shown in FIGS. 6A and 6B, the sleeve 60 is mounted so as to be fitted on the cylindrical projection 38 of the mounting board 36, and the outer periphery of the sleeve 60 has a rotating ring 61 and a strength. An adjustment spring 62 is rotatably mounted. The end of the gear portion 61a of the rotating ring 61 is in contact with a regulating protrusion 36c protruding from the mounting board 36, whereby the rotation of the rotating ring 61 in the counterclockwise direction in FIG. It is being regulated. The adjusting end 62 b of the strength adjusting spring 62 is inserted through the guide hole 63 a of the holding cap 63, and the locking hole 65 of the ratchet arm 65 is inserted.
Locked to d. On the other hand, the rotation end 62 of the strength adjusting spring 62
a is locked in the locking groove 61b of the rotating ring 61.

The holding cap 63 is fixed to the drive shaft 40 by nuts 68a and 68b with the drive shaft 40 inserted through the insertion hole 63b. Thereby, the holding cap 6

It is attached so as to rotate integrally with 0. The holding cap 63 is engaged with an engaging claw 66e on an engaging claw 63d of the mounting protrusion 63c. In this state, the screw holes 69c are fixed to the mounting protrusion 63c with screws 69a and 69b, so that the ratchet cover 66 is secured. Can be attached integrally.
That is, the holding cap 63 and the ratchet cover 66 are
It rotates integrally with the rotation of the drive shaft 40.

An end cap 67 is fitted and attached to the mounting hole 66b of the ratchet cover 66 by the engagement of the collar-shaped locking projection 66a and the engaging claw 67a. The internal space (the space in which the operation groove 65c of the ratchet arm 65 described later is accommodated) is covered in a sealed state. The end cap 67 is, as shown in FIG.
6 and fitted into the mounting hole 66b. For this reason, unless the end cap 67 and the ratchet cover 66 are broken and the end cap 67 is removed from the ratchet cover 66, the internal space of the emission intensity adjustment unit 34 cannot be opened. That is, the turning operation cannot be performed by the operation groove 65c in order to adjust the firing intensity.

The end cap 67 is made of an opaque black synthetic resin. When the end cap 67 is attached to the ratchet cover 66, the firing intensity adjusting section 3
The inside space of No. 4 cannot be visually recognized from the outside. That is, the operation groove 65c cannot be visually recognized.
For this reason, the operation unit (operation groove 65) of the emission intensity adjustment unit 34
Since it is not clear that c) is covered, it is possible to make it difficult to illegally operate the operation unit of the emission intensity adjustment unit 34 when it is attempted. The one-way screws 69a and 69b for assembling the holding cap 63 and the ratchet cover 66 are special screws that rotate only in the screw tightening direction, similarly to the one-way screw 95 described later in detail. Has become. For this reason, the ratchet cover 66 cannot be removed unless it is similarly destroyed.

A preload spring 64 and a ratchet arm 65 are accommodated between the front surface of the holding cap 63 and the inner wall surface of the ratchet cover 66. The ratchet arm 65 is attached so that the rotation shaft 65a is rotatably fitted in the insertion hole 40a of the drive shaft 40, and the rotation saw tooth surface 65b is meshed with the fixed saw tooth surface 66d of the ratchet cover 66. On the other hand, the preload spring 64 is composed of the ratchet arm 65 and the holding cap 63.
Are mounted so as to be sandwiched between them, and the elastic force urges the rotating saw tooth surface 65b and the fixed saw tooth surface 66d in the direction of meshing. Thus, if the operation groove 65c of the ratchet arm 65 is rotated with a flathead screwdriver, the meshing position between the rotating saw tooth surface 65b and the fixed saw tooth surface 66d can be changed against the urging force of the preload spring 64, When the rotation operation by the flathead screwdriver is completed in this state, the urging force of the preload spring 64 acts to hold the ratchet arm 65 at the displaced position. The rotational position of the adjustment end 62b of the strength adjustment spring 62 with respect to the drive shaft 40 is adjusted according to the displacement position of the ratchet arm 65, and the strength adjustment spring 6
2 is finely adjusted.

The operation for finely adjusting the firing force (operation for finely adjusting the amount of twist of the strength adjusting spring 62) by the above-described firing intensity adjusting unit 34 will be described. This operation is performed before the mounting of the end cap 67. This operation is performed by rotating the operation groove 65c of the ratchet arm 65 with a flathead screwdriver in a state where the internal space is opened (before shipment). Specifically, the ratchet arm 65
Is rotated, the locking hole 65 of the ratchet arm 65 is
The adjustment end 62b attached to the ratchet arm 6
5 is displaced in the same direction as the rotation direction. Therefore, when the ratchet arm 65 is rotated clockwise in FIG. 3A, the amount of twist of the strength adjusting spring 62 increases, and the firing force increases. On the other hand, the ratchet arm 65 is
When the counterclockwise rotation in (A) is performed, the amount of twist of the strength adjusting spring 62 decreases, so that the firing force decreases. In such a rotation operation of the ratchet arm 65, if the operation by the flathead screwdriver is completed as described above, the urging force of the preload spring 64 acts to hold the ratchet arm 65 at the displaced position. Therefore, it is not necessary to continue exerting an external force on the ratchet arm 65.

The operation transmitting section 35 has a connecting recess 70a on one side.
(See FIG. 3 (B)), while the rotating shaft 7 is
0b, a driven roller 71 having a gear portion 70c formed on the outer circumference, a driven roller 71 having a rotating shaft 71a protruded on one side and a gear portion 71b formed on the outer circumference, and rollers 70, 71.

It is possible to tighten the screw by rotating the head 96 in one direction with a normal flat-blade screwdriver tool. And the positioning with the one-way screw 95 can facilitate the tightening operation.

When the sealing cover 88 is fixed to the firing control board 81 with the one-way screw 95 as described above, unless the cutting portion 91 of the first mounting piece 90 is cut by a nipper tool or the like, The upper variable resistor 86 cannot be operated. Therefore, at the stage before sealing with the sealing cover 88 (for example, before shipment at a factory, or before delivery at a game hall and final inspection), the detection sensitivity is operated by operating the variable resistor 86. Can be adjusted, but at the stage after sealing with the sealing cover body 88 (for example, at the time of shipment from a factory or after the final inspection at the game hall), the variable resistor 86 is The detection sensitivity cannot be adjusted by operation.

If it becomes necessary to adjust the variable resistor 86 in a game arcade, the first
By cutting the cut portion 91 of the attachment piece 90 with a nipper tool or the like, the sealing cover body 88 can be removed. In this case, after the adjustment of the variable resistor 86 is completed, the sealed state can be reproduced again by screwing the one-way screw 95 into the mounting hole 94 of the second mounting piece 93 again. . After the second mounting piece 93 is screwed with the one-way screw 95, the variable resistor 86 cannot be operated unless the sealing cover body 88 itself is destroyed. In addition, cutting work and resealing work with one-way screw,
It is common that the service is performed by the manufacturer's serviceman, not by the clerk at the playground. Therefore, in this case, for example, it is desirable to provide an opening history seal and approve it by a person who has performed the work, or to attach a seal indicating that the cutting has been performed properly. The shape of the cutting section 91 is
Although not limited to the illustrated embodiment, a thinner and thinner width is desirable because it is easier to cut with a nipper tool or the like.

In the above-described embodiment, the one-way screw 95 is shown as a member for fixing the sealing cover body 88 (means for sealing). The mounting pieces 90 and 93 may be fixed with an adhesive or welding (including ultrasonic welding).
However, the screw tightening structure is preferable because the work is simpler. Further, as shown in FIG. 9, the sealing cover body 105 is formed in a cylindrical shape penetrating vertically, and the emission control board 81 is attached to a mounting piece 106 protruding from the outer peripheral side surface of the sealing cover body 105.
It is also conceivable that the one-way screw 95 is used to fasten the rear surface of the variable resistor 86 and the periphery of the variable resistor 86 is solidified by pouring the ultraviolet curing resin 107 into the cylindrical sealing space 108. In this case, when the cured ultraviolet curable resin 107 is destroyed, the mounted state of the variable resistor 86 becomes unstable.
In fact, the possibility that the detection sensitivity cannot be adjusted by the variable resistor 86 becomes extremely high. Also, instead of sealing the variable resistor 86 with the ultraviolet curing resin 107, for example, a screw for fixing the sealing cover body 88 having a closed top surface (in this case, it is not necessary to use a one-way screw). ) May be covered with a coating material containing the ultraviolet curable resin 107, or the variable resistor 86 may be directly covered with a coating material without providing a sealing member to be in a sealed state.

Further, as a structure in which the variable resistor 86 cannot be operated, as shown in FIG. 10, a special screw 1 which cannot be tightened or loosened unless a special tool is used.
09a to the mounting hole 9 of the first mounting piece 90 of the sealing cover body 88.
The variable resistor 86 may not be operated by screwing it into the mounting hole 94 of the second or second mounting piece 93.
Here, the special screw 109a has a three-pronged groove formed on its head that cannot be rotated with a normal flat-blade screwdriver and a plus-blade screwdriver, so that it can be rotated only with a special three-pronged screwdriver. I have. Further, in view of the fact that the variable resistor 86 as a variable resistor has a structure in which the resistance value is changed by rotating with a driver tool, as shown in FIG. You may comprise so that it may have the special head screw 109b which cannot be rotated unless it is used. In this case, the variable resistor 86a is connected to the sealing cover 8
It is not necessary to seal with a sealing member such as 8.

The configuration of the hit ball launching device 30 has been described above.
This is performed as shown below. That is, when the player operates the operation handle 29, the stepping motor 3
2 is driven, and the driving cam 52 rotates counterclockwise in FIG. 3B. Next, when the hit arm 46 and the hitting punch 31 are rotated clockwise in FIG. 3B by the rotation of the driving cam 52, the strength adjusting spring 62 of the firing strength adjusting unit 34 is further twisted and changed.
Thereafter, when the drive cam 52 further rotates to separate the drive cam 52 from the hit arm 46 (arm roller 46a), the hit arm 46 and the hitting punch 31 are moved counterclockwise together with the drive shaft 40 by the restoring force of the strength adjusting spring 62. To rotate. And the punch 31 rotated counterclockwise.
In this case, the ball sent from the ball supply device by the operation of the elevating rod 33 is hit with a mallet (spring 45) and fired into the game area. Also, at this time, if the rotating ring 61 of the firing intensity adjusting section 34 is rotated by operating the firing handle 29, the amount of twist of the intensity adjusting spring 62 accompanying the backward driving (clockwise rotation) of the hitting punch 31 is increased. Can be adjusted.
That is, the hitting force (firing force) of the hitting punch 31 can be adjusted.

The control of the hitting ball firing operation by the hitting ball firing device 30 is performed by a firing control circuit formed on the firing control board 81. This firing control circuit is as shown in FIG. Therefore, referring to FIG. 12, the clock pulse generated by the crystal oscillation circuit 126 is frequency-divided by the frequency divider 125 to generate a clock for the touch sensor circuit and a clock for motor excitation.
The motor excitation clock is a motor excitation pattern circuit 12.
The stepping motor 32 is driven to rotate via the motor 7 and a motor drive circuit 128. However, the motor excitation pattern circuit 127 is an AND circuit 1 described later.
23, that the ON operation signal (the main switch is ON) from the single fire switch 110 is derived, and that the fire control signal is not derived (management). This is activated when a condition that a signal for forcibly stopping the popping operation is not derived from the computer). The firing control signal may not be input from the viewpoint of fraud prevention.

On the other hand, the clock for the touch sensor circuit is used as follows. That is, a reference waveform adjusted by the variable resistor 86 (hereinafter referred to as a reference waveform) is input to CLOCK 1 of the first flip-flop 120. Further, when the player contacts the touch sensor 111 of the operation handle 29, a waveform affected by the external capacitance is input to the first flip-flop DATA1. At this time, if the waveform input to DATA1 is at L level with respect to the rising edge of the waveform input to CLOCK1, a resilient signal is output to AND circuit 123. That is, the first flip-flop 120 determines whether or not the first flip-flop 120 has touched the touch sensor 111 (contact portion).

The above-mentioned reference waveform is inputted to DATA2 of another second flip-flop 121, and a waveform of a threshold value which causes no response (spring prohibition) is generated in advance by the resistor 124. And the waveform is
Input to K2. At this time, if the waveform input to DATA2 is at L level with respect to the rising edge of the waveform input to CLOCK2, a resilient signal is output to the AND circuit 123.
When the variable resistor 86 is gradually turned in the direction of high sensitivity (high), when the waveform input to DATA2 rises to the H level with respect to the rising edge of the waveform input to CLOCK2 , A non-reaction state (spring prohibition state) occurs. That is, the second flip-flop 121
It is determined whether the sensitivity of the variable resistor 86 has been adjusted higher than a predetermined threshold value.

Thus, an L-level signal is output from the first flip-flop 120 (touching the touch sensor 111) and an L-level signal is also output from the second flip-flop 121 (adjustment of the variable resistor 86). Is less than or equal to the threshold), the AND circuit 123 derives a resilient operation permission signal to the motor excitation pattern circuit 127,
An L-level signal is output from the first flip-flop 120 (touching the touch sensor 111) and an H-level signal is output from the second flip-flop 121 (the adjustment of the variable resistor 86 is higher than the threshold). In this case, the AND circuit 123 does not derive the resilient operation permission signal to the motor excitation pattern circuit 127.

The resistor 1 for setting the threshold value
By replacing 24, the threshold value also changes, so that this resistor 124 cannot be replaced.
It is desirable to seal with a sealing member like the variable resistor 86. In this case, the sealing member having the same structure as that described for the sealing member of the variable resistor 86 can be used.

In the circuit configuration described above, the first flip-flop 120, the second flip-flop 121,
AND circuit 123, resistor 124, frequency divider 125, crystal oscillation circuit 126, variable resistor 86, touch sensor 111
And the like constitute a touch sensor circuit.

The hitting ball launching apparatus 30 according to the embodiment has been described above. According to the present embodiment, a touch sensor circuit for detecting whether or not a player has touched the touch sensor 111 (contact portion) is used. In the ball game machine 1 provided with the hit ball launching device 30 for hitting a hit ball according to a detection signal, the sensitivity adjustment of the variable resistor 86 for adjusting the detection sensitivity of the touch sensor circuit is adjusted to be higher than a predetermined threshold value. Sometimes, a first flip-flop 120 and a second flip-flop 121 for prohibiting the bouncing operation of the hit ball launching device 30 and an AND circuit 123 (bouncing operation prohibition control means) are provided. With such a configuration, even if the sensitivity is erroneously or intentionally adjusted so as to increase the sensitivity above a predetermined threshold value in the game arcade, it is determined whether or not there is a touch on the touch sensor 111 (contact portion). In spite of the fact that the hitting action of the hit ball is prohibited, a remarkable effect of not causing a problem in which the hitting action is performed even though the human body does not contact can be achieved.

In the present embodiment, the pop-up operation prohibition control means includes the touch sensor 111 (contact portion).
First flip-flop 12 that determines whether or not the
0 (a first flip-flop circuit), a second flip-flop 121 (a second flip-flop circuit) for determining whether or not the sensitivity of the variable resistor 86 has been adjusted to be higher than a predetermined threshold value; One flip-flop 120
(A first flip-flop circuit) and an AND circuit 123 to which a second flip-flop 121 (a second flip-flop circuit) is connected. When it is determined that the sensor 111 (contact portion) has been touched and the second flip-flop 121 (second flip-flop circuit) determines that the sensitivity has been adjusted to a predetermined threshold value or less, the AND circuit 123 From the first flip-flop 120 (first
Is determined to have touched the touch sensor 111 (contact portion) and the second flip-flop 121 (second flip-flop circuit) is determined to have sensitivity adjusted higher than a predetermined threshold. In this case, the pop-up operation permission signal is not derived from the AND circuit 123, so that the pop-up operation prohibition control means can be configured with a simple circuit configuration.

In this embodiment, the variable resistor 86 is sealed with a sealing cover 88 (sealing member) which cannot be operated unless it is destroyed. Adjustment is possible, and after the shipment, even if an attempt is made to adjust the detection sensitivity that causes fraud or malfunction, the sealing cover 88 (sealing member) must be destroyed. If the sealing cover body 88 (sealing member) is broken to perform the adjustment, it is known that the sensitivity has been adjusted by the trace, and therefore, unauthorized adjustment of the sensitivity after shipment can be prevented.

In the present embodiment, the sealing member is a sealing cover 88 covering the variable resistor 86. The sealing cover 88 is a one-way seal that cannot be released unless it is broken. First mounting piece 90 having a cut portion 91 fixed by screws 95 (fixing means) and easy to cut
(A first fixing portion) and a one-way screw 95 (fixing means) that cannot be released from the sealed state unless the cutting portion 91 is cut and the sealed state is released and then destroyed again after the sealing state is released. Since the two mounting pieces 93 (the second fixing portions) are integrally formed, the cutting portion 91 can be cut even after shipping, and the variable resistor 86 can be operated on the game arcade side, Then, the second mounting piece 93 (second fixing portion)
Can be re-sealed by fixing with a one-way screw 95 (fixing means), so that when a large adjustment is required at the game arcade, there is provided an opportunity to adjust the detection sensitivity only once. Can be. In other words, when a situation such as a decrease in sensitivity occurs, the sensitivity can be increased within an allowable range at least once.

In this embodiment, a resistor 124 for determining the threshold value is provided in the touch sensor circuit separately from the variable resistor 86, and the resistor 124 is sealed with a sealing member. By changing the resistor 124 serving as a reference for setting the threshold value by sealing, it is possible to prevent a fraudulent act that causes a problem in which a resilient operation is performed even when a human body does not touch the device. Can be.

In the above-described embodiment, the resistor 124 serving as a reference for setting the threshold value is described as having a fixed resistance value, but may be constituted by a variable resistor. As described above, when the resistor serving as the reference for setting the threshold value is constituted by a variable resistor, the threshold value can be finely adjusted. Also in this case, it is desirable that the operation cannot be performed on the game arcade side. Therefore, it is preferable to seal with a sealing member such as a sealing cover body 88 or to use a special head screw 109b.
It is desirable to be configured to have Also, in the AND circuit 123 of the present embodiment, the output of the H level (to derive the resilience permission signal) when there is an input of the L level and the L level has been described. But it is good. For example, it is also possible to derive a pop-out prohibition signal other than the L-level and L-level inputs, and not to derive the pop-out prohibition signal when there is an L-level and L-level input.
