[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 sensitivity adjustment unit for adjusting the detection sensitivity was provided. The sensitivity adjustment unit is configured so that the 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 the game arcade. Had become. For this reason, even if the operation handle is operated while the human body is in contact and it is in a state where it can be repelled, no hit ball can be released at all, or a state in which the human body cannot be repelled without contact and becomes in a state where it can be repelled. There is a risk that the adjustment of the game may be intentionally or erroneously made in the game hall. In order to solve such a drawback, it is conceivable that the adjustment range of the sensitivity adjustment unit is narrowed from the beginning. However, when the adjustment range of the sensitivity adjustment unit is narrowed, the ball game machine is There was a problem that proper adjustment was not possible at the time of factory shipment.

[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 equipped with a hit ball launching device that can adjust detection sensitivity properly at the time of shipment and does not cause irregularities or malfunctions by adjusting the detection sensitivity after shipment.

[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 provided with a hit ball launching device, a sensitivity adjustment unit for adjusting the detection sensitivity of the touch sensor circuit is sealed with a sealing member that cannot be operated unless destroyed. . With this configuration, before shipment, after adjusting the sensitivity adjustment unit to have an appropriate detection sensitivity, the sensitivity adjustment unit is sealed with a sealing member, and the product is shipped in a sealed state. Thus, the sensitivity adjustment unit cannot be operated in the game arcade. Therefore, at the time of shipment,
Appropriate adjustment of the detection sensitivity is possible, and a remarkable effect that it is not possible to adjust the detection sensitivity that causes fraud or malfunction after shipping can be achieved.

[0005] In the invention of claim 2, the sealing member is a sealing cover body that covers the sensitivity adjusting section,
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 sensitivity adjustment section can be operated on the playing field side, and then the second fixing section can be resealed by fixing the second fixing section with the fixing means. Sometimes, an opportunity to adjust the detection sensitivity only once can be provided. In this case, since the cut portion is cut, if the detection sensitivity after adjustment is not appropriate, by observing the cut portion, it is possible to determine whether the problem was intentionally or mistakenly performed. The judgment can be made easily.

In a third aspect of the present invention, the touch sensor circuit includes a second sensitivity adjustment unit that is not sealed differently from the sensitivity adjustment unit sealed by the sealing member. The sensitivity adjustment section 2 is configured so that the adjustment range of the detection sensitivity is set to be narrower than the sensitivity adjustment section sealed by the sealing member, thereby eliminating the disadvantage that the adjustment of the detection sensitivity in the game hall cannot be performed at all. While you can
Since the range of adjustment of the detection sensitivity on the game arcade side is reduced, there is an advantage that it is not possible to make an adjustment to the extent that a fraud or a problem occurs.

Further, in the invention of claim 4, a ball game machine equipped with a ball shooting device for hitting a ball with a detection signal from a touch sensor circuit for detecting whether or not the player has touched the contact portion. , Wherein the sensitivity adjustment unit for adjusting the detection sensitivity of the touch sensor circuit cannot be adjusted unless a special tool is used. With this configuration, before shipment, the sensitivity adjustment unit is adjusted with a special tool so as to have an appropriate detection sensitivity, and shipped in the adjusted state. The unit is configured so that it cannot be operated. For this reason, at the time of shipment, the detection sensitivity can be appropriately adjusted, and after shipment, a remarkable effect that the detection sensitivity that causes fraud or a defect cannot be adjusted can be obtained.

Further, in the touch sensor circuit according to the fifth aspect of the present invention, unlike the sensitivity adjuster which can be adjusted by the special tool, the touch sensor circuit can be adjusted without using a special tool. A sensitivity adjustment unit is provided, and the second sensitivity adjustment unit is configured to adjust the detection sensitivity in the game arcade by setting the detection sensitivity adjustment range narrower than the sensitivity adjustment unit that can be adjusted by the special tool. There is an advantage in that it is possible to eliminate the adverse effects that cannot be made at all and to reduce the adjustment range of the detection sensitivity at the game arcade side, so that it is not possible to make adjustments to the extent that injustice or trouble occurs.

In FIG. 2 to FIG.
Is a hitting punch 28 for repelling and firing a hitting ball, and the hitting punch 2
8, a stepping motor 23 that constitutes a driving source, a rotation transmitting member 25 that transmits the driving force of the stepping motor 23 to a ball hitting punch 28, and a ball supply device (not shown) that is operated each time a ball is fired. A ball feed rocking member 31 for feeding the next hit ball to the firing position, a rubber upper stopper 35 and a lower stopper 3 for restricting the rotation range of the hit ball punch 28
6 and a firing control board 50 for controlling the driving of the stepping motor 23 are mounted on the mounting base 21. Bend pieces 22 are formed on both left and right ends of the mounting base 21.
Positioning connection holes 22a for contacting the front surface frame 3 with the lower portion on the back side of the front frame 3 and positioning each other with the connection rod extending from the operation handle 11 being inserted. 3 is provided with a screw fixing hole 22b to be fixed thereto. When the bent piece 22 is attached to the front frame 3, the attachment base 21
Is concave on the front side (the side facing the front frame 3), and the hitting punch 28, the rotation transmitting member 25, and the upper and lower stoppers 35 and 36 are located in the concave portion, and the mounting base is formed. A fire control board 50 including the stepping motor 23 and the touch sensor circuit is located on the back side of the 21 (a side where the ball game machine 1 can be viewed from the back side). In addition, in addition to the above, the board mounting projections 37a to 37c,
8a to 38c, the protective cover locking hole 42 is formed by punching.

Next, a detailed description will be given of the relationship between the above-described components. The motor shaft 24 of the stepping motor 23 fixed to the rear side of the mounting base 21 projects to the front side of the mounting base 21 to transmit rotation. The member 25 is fixed via a fixing member 24a. A hitting punch 28 having a spring-made hammer 29 at the tip is rotatably loosely fitted on the outer periphery of the fixing member 24 a between the rotation transmitting member 25 and the mounting base 21. Although the rotation transmitting member 25 is formed in a cylindrical shape, a part of the outer periphery thereof is formed as a protruding connection piece 25a, and a semicircular outer circumference is formed from one rising portion of the connection protrusion 25a. The surface is a cam surface 25b. A locking pin 26 protrudes from the connecting protruding piece 25a, and a spring 27 is connected between the locking pin 26 and a locking pin 30 protruding from a middle side surface of the hitting punch 28. The cam surface 25b contacts the other cam contact surface 33 of the ball-feeding rocking member 31, and swings the ball-feeding rocking member 31 following the turning operation of the rotation transmitting member 25. It is.
Further, as shown in FIG. 4, the rotation transmitting member 25 is provided with a transmission pin 25c which comes into contact with the inside of the base of the hitting punch 28.

The ball-feeding rocking member 31 has a U shape,
The bent portion is pivotally supported by the mounting base 21 by the pivot pin 32. A ball feed contact piece 34 for operating a ball supply device (not shown) is formed on the upper side of the ball feed rocking member 31, while the cam surface of the rotation transmitting member 25 is formed on the lower side of the ball feed rocking member 31. A cam contact surface 33 that comes into contact with 25b is formed.

The hitting punch 28 configured as described above repeatedly performs four sequence operations when the player rotates the operation handle 11 to a predetermined angle and the stepping motor 23 is driven and controlled. First, in the ball striking operation which is the first operation, the striking punch 28 resting at the position shown by the two-dot chain line in FIG.
Is rotated counterclockwise to the position (hereinafter referred to as forward rotation). As a result, the hammer 29 of the hitting ball punch 28 hits the ball and fires the ball into the game area. At this time,
The driving of the stepping motor 23 is a force corresponding to the rotation angle of the operation handle 11 (the resistance value of the variable resistor changes according to the rotation angle of the operation handle 11 to change the torque). And transmitted to a hitting punch 28 via a spring 27. In addition, the speed in the ball hitting operation starts slowly at first,
This is performed by slow-up control that gradually accelerates. This is particularly effective in preventing step-out and maintaining a constant rotation angle when the stepping motor 23 is used as the drive source as in the present embodiment.

In the first pause operation as the second operation, when the hitting punch 28 rotates forward to the position of the upper stopper 35 (hereinafter referred to as a hitting position), the driving of the stepping motor 23 is stopped for a certain time. . This allows
The hitting punch 28 is held at the hitting position for a certain period of time until the rotational vibration converges.

In the third operation, the recovery / ball supply operation, the hitting ball punch 28 at the hitting position is
By the drive of 3, the lower stopper 36 is rotated clockwise (hereinafter, referred to as reverse rotation) to the position of the lower stopper 36 (hereinafter, referred to as a stationary position). At this time, the drive of the stepping motor 23 is transmitted to the hitting punch 28 via the transmission pin 25c of the rotation transmission member 25. At the same time,
The rotation transmitting member 25 rotates the ball feed rocking member 31 that is in contact with and engaged with the cam surface 25b in a counterclockwise direction. Thereby, the ball feed contact piece 34 of the ball feed rocking member 31 is pushed up, and one hit ball is supplied from a ball supply device (not shown) to the firing position of the firing rail. The speed in the recovery / ball supply operation may be basically a slow constant speed. However, the speed is not limited to this, and the operation period is divided into two periods, and the speed in the second period is higher than the speed in the first period. It is also possible to supply the ball at a slower speed.

In the second pause operation, which is the fourth operation, when the hitting punch 28 rotates in the reverse direction to the rest position, the driving of the stepping motor 23 is stopped for a certain time. As a result, the hitting punch 28 is held at the stationary position for a certain period of time until the rotational vibration converges. Thereafter, the next ball striking operation is started at a cycle of less than 100 shots per minute, and the same sequence operation as described above is repeated.

The firing control board 50 for controlling the above-described sequence operation is mounted on the back side of the mounting base 21 and beside the stepping motor 23. The mounting is performed by the board mounting projections 37a to 37c protruding by punching out the mounting base 21 and the cover mounting piece 38c. That is, the board mounting projection 37 that locks the upper side and one side of the firing control board 50.
a and 37c (two upper and lower 37c) are formed in a key shape so as to engage with the upper surface of the firing control board 50, and the board mounting projections 37 which lock the other side of the firing control board 50 are provided.
b is formed so as to be in contact with the side surface of the emission control board 50. Then, the firing control board 50 is attached to the mounting base 2.
1 is inserted from below into the board mounting projections 37b, 37c so as to abut or engage with the board mounting projections 37b, 37c. The firing control board 50 can be mounted on the mounting base 21 by fixing the screw 43 so as to match a stop hole (not shown) formed in the firing control board 50.

The firing control board 50 includes various electronic components 52 including the variable resistors 54 and 55, the variable resistor 5
4, 55 and a connector 53 are mounted, and a connector 51 extended from the stepping motor 23 is connected to control the driving of the stepping motor 23. The two variable resistors 54 and 55 constitute a sensitivity adjustment unit that changes the detection sensitivity of the touch sensor circuit 102 (see FIG. 8) described in detail later. The adjustment range of the detection sensitivity is wide, and the variable resistor 55 arranged at the top is set so that the adjustment range is narrow. In the present embodiment, the variable resistor 54 having a wide adjustment range is sealed by a sealing cover 70 as a sealing member described later in detail. For this reason, the first through hole 56 and the second through hole 57 for attaching the sealing cover body 70 are formed in the emission control board 50. Note that the variable resistor 54,
The resistance value 55 can be easily changed by turning operation with a normal minus or plus driver tool.

The above-described emission control board 50 is covered with a protective cover body 60. The protective cover body 60
Locking claws 61 for mounting the protective cover body 60 in the protective cover locking holes 42 of the mounting base 21 at two upper positions and one lower position of the open-side edge of the box. Is protruding. Further, a connection opening 62 for connecting the connector 53 and an external electric component is cut out on one side of the protective cover body 60, and the variable resistor 55 is provided on the upper surface of the protective cover body 60. An opening 63 for operation is opened at a position corresponding to the variable resistor 54, and a sealing cover insertion opening 64 for penetrating a sealing cover 70 described below is opened at a position corresponding to the variable resistor 54. Therefore, when the emission control board 50 is covered with the protective cover body 60, the upper variable resistor 55 can be operated through the operation opening 63, but the lower variable resistor 54 is sealed. It cannot be operated because it is covered by the stop cover body 70.

As shown in FIG. 5, the sealing cover 70 inserted into the sealing cover insertion opening 64 is formed in a cylindrical shape whose upper surface is closed, and a variable resistor is provided in the cylindrical sealing space 71. 54 is sealed so that it cannot be operated. Further, a first mounting piece 72 formed in a crank shape from the middle of the outer peripheral surface of the sealing cover body 70 is protruded from a target position, and a base of the first mounting piece 72 can be cut by a tool such as a nipper. It has become. In addition, a mounting hole 74 is formed at the tip of the first mounting piece 72. Further, the first mounting piece 7 is attached to the sealing cover 70 from the open end of the outer peripheral surface thereof.
A pair of second mounting pieces 75 are protruded at positions perpendicular to 2. Although the second mounting piece 75 is not configured to be cut, a mounting hole 76 is formed.

The sealing cover 70 constructed as described above
In order to cover the variable resistor 54 on the firing control board 50 so as to cover the variable resistor 54, the one-way screw 77 is attached with the mounting hole 74 of the first mounting piece 72 corresponding to the first through hole 56 of the firing control board 50. Attach. On the back surface of the first through hole 56, first stopper holes 39a, 39 formed in the cover mounting pieces 38a, 38b formed by punching the mounting base 21.
Since b is located, the tip of the one-way screw 77 is screwed into the first stopper holes 39a and 39b. Thus, the sealing cover 70 is fixed to the mounting base 21 so as to close the variable resistor 54. The mounting hole 76 of the second mounting piece 75 corresponds to the second through-hole 57 of the firing control board 50, and a cover mounting piece 38 a formed by punching the mounting base 21 on the back surface of the second through-hole 57. , 3
8c are located at the second stop holes 40a, 40b,
By being screwed with the one-way screw 77, the sealing cover 70 is fixed to the mounting base 21 so as to close the variable resistor 54. However, the reason why the one-way screw 77 is screwed to the second mounting piece 75 is to reproduce a re-sealed state, as described later in detail.

Incidentally, the one-way screw 77 is a special screw which turns only in the screw tightening direction, and cannot be removed once tightened. Specifically, FIG.
As shown in (B), a screw groove formed in the head portion 78 is constituted by a contact surface portion 79, a concave portion 80, and a center hole portion 81. When the screw is to be tightened with the special flathead screwdriver tool 82 shown in FIGS. 6C and 6D, the center shaft portion 83 of the screwdriver tool 82 is inserted into the center hole 81, and from this state, the contact of the screwdriver tool 82 is performed. The contact piece portion 84 is brought into contact with the contact surface portion 79 in one direction (clockwise direction in FIG. 6A).
The screw is tightened by rotating the head 78 at a time. on the other hand,
When the head 78 is rotated in the other direction (counterclockwise in FIG. 6A) by the driver tool 82 and the one-way screw 77 is to be removed, the driver tool 82 slips into the concave portion 80 and slips. As a result, the one-way screw 77 cannot be removed because the head 78 cannot be rotated. Note that it is possible to rotate the head 78 in one direction and tighten the screw with a normal flathead screwdriver tool. However, like the special flathead screwdriver tool 82, the center shaft 83 is connected to the center hole 81 of the one-way screw 77. And the positioning with the one-way screw 77 can facilitate the tightening operation.

When the sealing cover 70 is fixed to the mounting base 21 with the one-way screw 77 as described above, the first
The variable resistor 54 on the firing control board 50 cannot be operated unless the cutting portion 73 of the mounting piece 72 is cut with a nipper tool or the like. For this reason, at the stage before sealing with the sealing cover body 70 (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 54. Can be adjusted, but at the stage after sealing with the sealing cover body 70 (for example, at the time of shipment from the factory, or after the final inspection at the amusement park),
The detection sensitivity cannot be adjusted by operating the variable resistor 54.

If it becomes necessary to adjust the variable resistor 54 in a game arcade, the first
By cutting the cutting portion 73 of the attachment piece 72 with a nipper tool or the like, the sealing cover body 70 can be removed. In this case, after the adjustment of the variable resistor 54 is completed, the one-way screw 77 is screwed into the mounting hole 76 of the second mounting piece 75 again, so that the sealed state can be reproduced again. . After the second mounting piece 75 is screwed with the one-way screw 77, the variable resistor 54 cannot be operated unless the sealing cover body 70 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 portion 73 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 77 is shown as a means for fixing the sealing cover body 70 (means for sealing). The mounting pieces 72 and 75 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. 7, the sealing cover 90 is formed in a cylindrical shape penetrating vertically, and the mounting piece 91 projecting from the outer peripheral side surface of the sealing cover 90 is one-way from the back surface of the emission control board 50. Fastened with the screw 77, the cylindrical sealing space 93
It is also conceivable that the periphery of the variable resistor 54 is hardened by pouring the ultraviolet curable resin 92 into the substrate. In this case, when the cured ultraviolet curable resin 92 is destroyed, the mounting state of the variable resistor 54 becomes unstable, so that the detection sensitivity may not be effectively adjusted by the variable resistor 54. Becomes extremely high. Also, the ultraviolet curable resin 9
Instead of sealing the variable resistor 54 with 2, for example, a screw (in this case, not a one-way screw) for fixing the sealing cover body 70 having a closed top surface is made of an ultraviolet curable resin. The variable resistor 54 may be covered with a coating material including the sealing material 92, or may be directly covered with a coating material without providing a sealing member to be in a sealed state.

Next, the circuit configuration and operation of the firing control board 50 for controlling the driving of the stepping motor 23 will be described with reference to FIGS. FIG. 8 is a circuit diagram illustrating a circuit formed on the emission control board 50 in a block configuration, and FIG. 9 is a circuit diagram illustrating a change in voltage input to the touch sensor circuit 102.

As shown in FIG. 8, the firing control board 50
Speed control circuit section 100, contact section 101, touch sensor circuit 102, sequence control circuit section 103, torque control circuit section 104, motor drive circuit 105, and power supply circuit 10
6 is configured.

The speed control circuit section 100 generates a voltage for controlling the rotation speed of the stepping motor 23 during each of the ball hitting operation and the restoring / ball supplying operation. 8, a voltage that gradually increases in accordance with the rotation operation angle with respect to the operation knob (displayed as an operation knob) is generated, and a predetermined voltage is generated in the recovery / ball supply operation period. Further, the speed control circuit unit 100 integrates a voltage proportional to the rotation operation angle with respect to the operation handle 11 to calculate the sequence control circuit unit 103
Output to

The touch sensor circuit 102 generates a firing permission signal while the human body is in contact with a contact portion 101 (a ring-shaped or plate-shaped member attached to the operation handle 11) attached to the operation handle 11 for detecting a human body. (It refers to a state in which the motor can rotate, and the state in which the motor rotates when the touch sensor is turned on, or when the main switch in the operation handle is turned on when the touch sensor is turned on or when the touch switch is turned on, the motor is turned on. Any of the rotating states may be used), that is, a predetermined clock is output to the sequence control circuit unit 103. However, the touch sensor circuit 10
2, the player operates the contact portion 101 of the operation handle 11.
It is possible to adjust the detection sensitivity as to whether or not the contact is made. This is based on the principle of the touch sensor, for example, by using a method in which a short wave is generated by a CR oscillation circuit, and a slight voltage level divided by the circuit and the human body is detected and output by touching the human body. Therefore, the detection sensitivity changes due to the influence of stray capacitance and the variation of the human body (the size of the human body and the grounding state "hands, feet, footwear, chairs, etc."), and it is necessary to adjust the detection sensitivity. Because it becomes. Of course, principles other than the above-described principle of the touch sensor, for example, a method in which a human body uses a high-frequency oscillation circuit to detect and stop the cause of oscillation, or an electrode dielectric noise is received by the human body and input to a CMOS gate through a contact portion and amplified. In the method of performing detection by smoothing and switching, it is necessary to adjust the sensitivity more or less.

Here, the detection sensitivity of the touch sensor circuit 102 is adjusted as shown in FIG.
It can be set by the respective resistance values of the variable resistor 54 sealed with 0 and the variable resistor 55 that can be set in the game arcade, and is connected in series compared to the resistance value of the resistor R1. Can be adjusted so that the total resistance value of the resistor R2 and the variable resistors 54 and 55 becomes large, and the sensitivity increases when the difference is large, and decreases when the difference is small. . Then, even if the player touches the contact portion 101 of the operation handle 11, the ball is not hit, or the hit ball is hit without contacting the contact portion 101. The variable resistors 54 and 55 are set in advance so as not to cause such a problem.

Thus, the adjustment range of the detection sensitivity of the variable resistor 55 that can be set at the game arcade is such that the detection sensitivity is set to the minimum value, and
When the human body comes into contact with 01, the resilient state can reliably appear even if the effects of stray capacitance and the effects of human body variation are taken into account, while operating with the detection sensitivity set to the maximum value. When the human body does not come into contact with the contact portion 101 of the handle 11, even if the influence of the stray capacitance and the influence of the variation of the human body are taken into account, the range in which the non-resilient state can be surely appeared. On the other hand, the adjustment range of the detection sensitivity of the variable resistor 54 that can be adjusted and set before shipment can be set in a range exceeding the above-described range of the minimum value and the maximum value of the variable resistor 55.

Therefore, in the operation of adjusting the detection sensitivity of the variable resistor 54 before shipment, even if the detection sensitivity of the variable resistor 55 is changed from the minimum value to the maximum value, the contact portion 101 of the operation handle 11 is placed on the human body. The detection sensitivity is set so that a resilient state can be reliably generated when a contact is made, and a non-resilient state can be reliably generated when a human body does not contact the contact portion 101. Variable resistor 5 before shipping
If the detection sensitivity of the variable resistor 55 is set as described above, it is not necessary to change the detection sensitivity of the variable resistor 55 that can be set and operated on the game hall for a certain long period. The variable resistor 55 to be obtained may be excluded from the emission control substrate 50 and only the variable resistor 54 sealed by the sealing cover 70 may be provided on the emission control substrate 50.

The sequence control circuit unit 103 controls switching of the above-described four sequence operations and generates a drive pattern signal and a drive voltage switching signal necessary for driving the stepping motor 23.

The torque control circuit 104 switches the torque according to the difference between the torque of the stepping motor 23 required at the first operation and the torque of the stepping motor 23 required at the second and third operations. More specifically, the voltage supplied to the motor drive circuit 105 is switched. Further, the torque control circuit unit 104 outputs a high-level and a low-level drive voltage in response to the drive voltage switching signal from the sequence control circuit unit 103.

The motor drive circuit 105 rotationally drives the stepping motor 23 according to the drive voltage supplied from the torque control circuit 104 and the drive pattern signal from the sequence control circuit 103. The power supply circuit 106 rectifies the AC power from the commercial power supply AC, supplies the smoothed DC power to the torque control circuit unit 104, controls the voltage value of the DC power to a predetermined constant voltage, and controls the smoothed DC voltage. Is supplied to various circuits.

Next, the operation of the firing control board 50 in accordance with the above-described sequence operation will be briefly described. When the power is turned on without the player touching the electrode 101, the other circuits do not operate. Since the drive control for the stepping motor 23 is in the OFF state, the fourth operation state, that is, the hitting punch 28 is in a state of waiting at the stationary position. Next, when the player touches the electrode 101, a predetermined clock is supplied from the touch sensor circuit 102 to the sequence control circuit unit 103. When a trigger signal is output from a timer (not shown) in this state, the sequence proceeds to the first operation sequence.

In the first operation sequence, a gradually increasing voltage is input from the speed control circuit unit 100 to the sequence control circuit unit 103. The sequence control circuit 103
In order to output a drive pulse having a frequency proportional to the value of the input voltage (here, a drive pulse that gradually changes from a low frequency to a high frequency), the stepping motor 23 is first started slowly at first, and then gradually accelerated. A drive pattern signal for making a positive rotation at a certain angle is output to the motor drive circuit 105. The motor drive circuit 105 is supplied with a high-level drive voltage from the torque control circuit unit 104. Accordingly, a hitting punch 28 connected to the stepping motor 23 via the spring 18 and the rotation transmitting member 25
Starts slowly rotating counterclockwise from the rest position in contact with the lower stopper 36, rotates gradually at a higher speed, and reaches a hitting position in contact with the upper stopper 35. At this time, if a hit ball has already been supplied, the hit ball is hit and fired by the hammer 29 of the hit ball punch 28.

Next, when the first sequence operation for rotating the hitting punch 28 to the hitting position is completed, the operation shifts to the second sequence operation. In the second sequence operation, the drive pulse from the speed control circuit unit 100 disappears and no drive pattern signal is output. On the other hand, at this time, the drive voltage switching signal is switched to the low level, but the motor drive circuit 105 continues to supply current to the stepping motor 23, and the hitting punch 28 remains held at the hitting position.

Next, when the sequence operation for a certain period of time until the vibration of the hitting punch 28 converges is completed,
Shift to the third sequence operation. In the third sequence operation, a substantially constant voltage is input from the speed control circuit unit 100 to the sequence control circuit unit 103. The sequence control circuit 103 outputs a drive pulse having a frequency proportional to the value of the input voltage V, that is, a drive pulse having a lower frequency than that in the first sequence operation. A drive pattern signal for clockwise rotation is output to the motor drive circuit 105. The motor drive circuit 105 includes a torque control circuit unit 10.
4, a low-level drive voltage is supplied. Accordingly, the hitting punch 28 rotates clockwise at a substantially constant speed from the striking position in contact with the upper stopper 35 and returns to the rest position in contact with the lower stopper 36. During this time, the ball feed swinging member 31 is rotated by the cam surface 25b of the rotation transmitting member 25, and the ball feed contact piece 34 is pushed up slowly. As a result, the ball supply device is operated, and one ball is reliably supplied to a position corresponding to the hammer portion 29 in the hitting position of the ball hitting punch 28.

Next, when the third sequence operation for rotating the hitting punch 28 to the rest position is completed, the process proceeds to a fourth sequence operation. In the fourth sequence operation, the drive pulse from the speed control circuit section 100 disappears, the drive pattern signal is not output, and the motor drive circuit 105 is turned off to supply no current to the stepping motor 23. Accordingly, the hitting punch 28 remains stationary at the stationary position. Thereafter, if the player keeps touching the electrode 101, the first to fourth sequence operations similar to the above are repeated from the time when the next trigger signal is output from a timer (not shown).

The embodiment has been described above.
According to the present embodiment, in the ball game machine 1 provided with the ball launch device 20 that launches a ball based on a detection signal from the touch sensor circuit 102 that detects whether the player has touched the contact portion 101, The variable resistor 54 (sensitivity adjuster) for adjusting the detection sensitivity of the touch sensor circuit 102 is sealed with a sealing cover 70 (sealing member) that cannot be operated unless destroyed, so that the variable resistor 54 can be changed before shipment. After adjusting the resistor 54 (sensitivity adjusting unit) to have an appropriate detection sensitivity, the variable resistor 54 (sensitivity adjusting unit) was sealed with a sealing cover body 70 (sealing member), and the sealing was performed. By shipping in a state, the variable resistor 54 (sensitivity adjustment unit) cannot be operated in the game arcade.
For this reason, at the time of shipment, the detection sensitivity can be appropriately adjusted, and after shipment, a remarkable effect that the detection sensitivity that causes fraud or a defect cannot be adjusted can be obtained.

In the above embodiment, the sealing member is the sealing cover 70 that covers the variable resistor 54 (sensitivity adjusting section), and the sealing cover 70 is sealed unless destroyed. A first mounting piece 72 (first fixing portion) having a cutting portion 73 which is fixed by a one-way screw 77 (fixing means) which cannot be released and which can be easily cut;
The one-way screw 7 whose sealing state cannot be released unless it is cut off and the sealing state is released and then destroyed again
Since the second mounting piece 75 (second fixing portion) fixed by 7 (fixing means) is integrally formed, the cutting portion 73 is cut even after shipping and can be changed on the game arcade side. The resistor 54 (sensitivity adjustment unit) can be operated, and thereafter,
The second mounting piece 75 (second fixing portion) is connected to the one-way screw 77.
Since the sealing state can be obtained again by fixing with the (fixing means), it is possible to provide an opportunity to adjust the detection sensitivity only once when a large adjustment is required on the game arcade side. In this case, since the cutting section 73 is cut,
When the detection sensitivity after adjustment is not appropriate, by observing the cut portion 73, it is possible to easily determine whether the defect has been performed intentionally or erroneously.

Further, in the above embodiment, the touch sensor circuit 102 is sealed differently from the variable resistor 54 (sensitivity adjuster) sealed by the sealing cover 70 (sealing member). A variable resistor 55 (second sensitivity adjustment unit) is provided, and the variable resistor 55 (second sensitivity adjustment unit) is a variable resistor sealed by the sealing cover body 70 (sealing member). By setting the adjustment range of the detection sensitivity to be narrower than 54 (sensitivity adjustment unit), it is possible to eliminate the disadvantage that the adjustment of the detection sensitivity in the game arcade cannot be performed at all, and to adjust the detection sensitivity in the game arcade side. Since the range is reduced, there is an advantage that it is not possible to make adjustments to such a degree as to cause fraud or malfunction.

In the above-described embodiment (hereinafter, referred to as a first embodiment), a structure in which the variable resistor 54 as the sensitivity adjusting unit cannot be operated is provided as long as the sealing cover 70 as the sealing member is not broken. Although the one-way screw 77 has been described as an example of the fixing means that cannot be removed,
As shown in FIG. 10, a special screw 110 that cannot be tightened or loosened unless a special tool is used is attached to the mounting hole 74 of the first mounting piece 72 of the sealing cover body 70 or the second mounting screw 74.
By screwing into the mounting hole 76 of the mounting piece 75, the variable resistor 54 may not be operated. Here, the special screw 110 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. In addition, in view of the fact that the variable resistor 54 as the sensitivity adjustment unit 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 111 which cannot be rotated unless it is used. In this case, it is not necessary to seal the variable resistor 54a with a sealing member such as a sealing cover body 70, and the variable resistor 55 that can be operated on the game arcade side is provided with a normal minus or plus driver tool. Can be rotated.

In the embodiment shown in FIGS. 10 and 11 (hereinafter, referred to as a second embodiment), the touch sensor circuit 102 for detecting whether or not the player has touched the contact portion 101 is used. In the ball game machine 1 provided with the hit ball launching device 20 for hitting a hit ball according to the detection signal, the variable resistors 54 and 54a (sensitivity adjuster) for adjusting the detection sensitivity of the touch sensor circuit 102 are connected to a special tool. Special screw 11 so that adjustment operation cannot be performed unless used.
By using 0,111, before shipping,
The variable resistors 54, 54a (sensitivity adjusters) are adjusted with a special tool so as to have an appropriate detection sensitivity, and shipped in the adjusted state so that the variable resistors 54, 54a ( (Sensitivity adjustment unit) cannot be operated. For this reason, at the time of shipment, the detection sensitivity can be appropriately adjusted, and after shipment, a remarkable effect that the detection sensitivity that causes fraud or a defect cannot be adjusted can be obtained.

Further, in the second embodiment, unlike the variable resistors 54 and 54a (sensitivity adjuster) which can be adjusted by the special tool, the touch sensor circuit 102 does not use a special tool. A variable resistor 55 (second sensitivity adjusting unit) is provided which can be adjusted even by the variable resistor 55 (second sensitivity adjusting unit). The variable resistor 55 (second sensitivity adjusting unit) can be adjusted by the special tool. (Sensitivity adjuster)
By setting the adjustment range of the detection sensitivity to be narrower than that, it is possible to eliminate the disadvantage that the adjustment of the detection sensitivity in the game hall cannot be performed at all, and to reduce the adjustment range of the detection sensitivity in the game hall side, There is an advantage that adjustment cannot be performed to such an extent that an injustice or a defect occurs.

In the first and second embodiments described above, a sensitivity adjustment unit that can adjust the detection sensitivity of the touch sensor circuit 102 before shipment and the like and a sensitivity that can be adjusted at the game hall after shipment and the like. Although the one provided with the adjusting unit is shown, the sensitivity adjusting unit cannot adjust the firing intensity of the hit ball, but the speed control circuit unit 100 can adjust the firing intensity of the hit ball. As described above, the speed control circuit unit 100 generates a voltage for controlling the rotation speed of the stepping motor 23. By changing the voltage, the speed control circuit unit 100 changes the rotation speed to adjust the firing intensity. Can be. Thus, in order to adjust the firing intensity, the firing control board 50 is provided with a firing intensity adjusting unit that can be adjusted before shipping and the like and a second firing intensity adjusting unit that can be adjusted at the game arcade after shipping and the like. Of these, the emission intensity adjustment unit that can be adjusted before shipment or the like is sealed with a sealing member as in the first embodiment or the second embodiment described above, or can be operated only with a special tool, and the second By enabling the launch intensity adjustment unit to be operated without using a special tool without sealing with a sealing member, the launch intensity can be properly adjusted before shipment, and the launch intensity that causes injustice or failure after shipment Can not be adjusted.

Here, the generation of the voltage in the speed control circuit section 100 will be briefly described. As shown in FIG. 12, a variable resistor 107 that can be changed by rotating the operation handle 11 and a sealing member such as the first embodiment are used. The voltage generated from the speed control circuit unit 100 by the respective resistance values of the variable resistor 108 sealed with the same sealing cover body 70 and the variable resistor 109 that can be set in the game arcade. Is determined. Of these, the variable resistor 10
The resistance value set by 8, 109 is not changed during the game of the player, and is only the resistance value of the variable resistor 107 changed by the rotation operation of the operation handle 11 during the game. In the case where the hit ball does not reach the desired position in the game area with respect to the amount of rotation of the operation handle 11, the player may feel uncomfortable. It can be set so that such a problem does not occur.

The adjustment range of the variable resistor 109 that can be set at the game hall is such that the operation handle 11 is rotated from the minimum rotation position to the maximum rotation position when the set value is set to the minimum value. From the entrance of the game area located diagonally to the upper left of the game area to the impact member (formed of rubber or synthetic resin) located diagonally to the upper right of the game area when the ball hit when operated is A state that can be reached can be appeared. On the other hand, in a state where the set value is set to the maximum value, a hit that is generated when the operation handle 11 is rotated from the minimum rotation position to the maximum rotation position is performed. This is a range in which a state in which a ball can reach from the entrance of the game area located diagonally upper left of the game area to the stop member located diagonally upper right of the game area can appear. On the other hand, the adjustment range of the variable resistor 108 that can be adjusted and set before shipment can be set in a range exceeding the range between the minimum value and the maximum value of the variable resistor 109 described above. It should be noted that only the minimum value described above is set in the adjustment range of the variable resistor 109, and the maximum value need not be set (that is, the adjustment range is equal to or more than the minimum value).

Therefore, in the adjustment operation of the variable resistor 108 before shipment, even if the set value of the variable resistor 109 is changed from the minimum value to the maximum value, the operation handle 11 is moved from the minimum rotation position to the maximum value. When the ball hit when rotated to the rotation position can reach from the entrance of the game area located at the upper left of the game area to the stop member located at the upper right of the game area. The setting value is set so that the state can appear. Variable resistor 108 before shipping
Is set as described above, it is not necessary to change the set value of the variable resistor 109 which can be set and operated on the game hall for a certain long period of time, so that the set operation can be performed on the game hall side The variable resistor 109 may be excluded from the emission control board 50 and only the variable resistor 108 sealed by the sealing cover 70 may be provided on the emission control board 50.

As described above, the following inventions can be considered as inventions that can be grasped when the sensitivity adjustment unit shown in FIG. 9 and the emission intensity adjustment unit shown in FIG. 12 are provided on the emission control board 50.

Since the (emission intensity adjustment unit) is sealed with the sealing cover body 70 (sealing member) which cannot be operated unless it is destroyed, the variable resistor 54 (sensitivity adjustment unit) and the variable resistor 108 ( After adjusting the emission intensity adjustment unit) to have an appropriate detection sensitivity, the variable resistor 54 (sensitivity adjustment unit)
The variable resistor 108 (emission intensity adjustment unit) is sealed with a sealing cover body 70 (sealing member), and shipped in the sealed state, so that the variable resistor 54 (sensitivity adjustment unit) and By configuring the variable resistor 108 (emission intensity adjustment unit) so that it cannot be operated, it is possible to properly adjust the detection sensitivity and the emission intensity at the time of shipment, and to make a mistake or malfunction after shipment. The remarkable effect that the detection sensitivity and the emission intensity that cause the above cannot be adjusted can be achieved.

(2) The sealing member is formed of the variable resistor 5

The sealing cover body 70 is fixed with a one-way screw 77 (fixing means) that cannot release the sealing state unless destroyed, and has a first mounting piece 72 (first fixing part) having a cut part 73 that is easy to cut. After the cut portion 73 is cut and the sealed state is released, the sealed state cannot be released unless it is destroyed again after the cutting state is released. Is formed integrally with the cutting portion 7 even after shipping.
3 is cut and the variable resistor 54 (sensitivity adjustment unit) is set at the game arcade.
Then, the variable resistor 108 (emission intensity adjusting unit) can be operated, and then the second mounting piece 75 (second fixing unit) is fixed with the one-way screw 77 (fixing means) to re-establish the sealed state. Therefore, when a large adjustment is required on the game hall side, it is possible to provide an opportunity to adjust the detection sensitivity and the firing intensity only once. In this case, the cutting section 73 is cut, and if the adjusted detection sensitivity and emission intensity are not appropriate, the cutting section 73 is cut.
By observing, it is possible to easily determine whether or not the defect has been performed intentionally or erroneously.

(3) The variable resistor 54 (sensitivity adjustment unit) and the variable resistor 108 (emission intensity adjustment unit) sealed by the sealing cover 70 (sealing member) are provided on the emission control board 50. Variable resistor 55 that is not sealed differently from
(Second sensitivity adjustment unit) and a variable resistor 109 (second emission intensity adjustment unit), and the variable resistor 55 (second sensitivity adjustment unit) and the variable resistor 109 (second emission intensity adjustment). ) Has a narrower detection sensitivity adjustment range than the variable resistor 54 (sensitivity adjustment unit) and the variable resistor 108 (emission intensity adjustment unit) sealed by the sealing cover 70 (sealing member). By being set, it is possible to eliminate the disadvantage that the detection sensitivity and firing intensity cannot be adjusted at all in the game arcade, and to reduce the adjustment range of the detection sensitivity and emission intensity in the game arcade, so that there is no injustice or malfunction. There is an advantage that adjustments to the extent that they can be made cannot be made.

(4) In the ball game machine 1 provided with the ball launch device 20 for launching a ball by a detection signal from the touch sensor circuit 102 for detecting whether or not the player has touched the contact portion 101, Variable resistors 54 and 54a for adjusting the detection sensitivity of the touch sensor circuit 102 (sensitivity adjustment unit)
The special resistor 110 (111) for adjusting the firing intensity of the hitting ball firing device 20 (the firing intensity adjusting unit) is not used unless special tools are used. , Variable resistor 5
4, 54a (sensitivity adjustment unit) and variable resistor 108 (firing intensity adjustment unit) are adjusted with a special tool so as to have an appropriate detection sensitivity, and shipped in the adjusted state. Variable resistors 54, 54a
(Sensitivity adjustment unit) and variable resistor 108 (emission intensity adjustment unit)

(5) The firing control board 50 has variable resistors 54, 54a which can be adjusted by the special tool.
Unlike the (sensitivity adjustment unit) and the variable resistor 108 (emission intensity adjustment unit), the variable resistor 55 (second sensitivity adjustment unit) and the variable resistor 109 (can be adjusted without using a special tool) A second firing intensity adjustment unit) is provided, and the variable resistor 55 (second sensitivity adjustment unit) and the variable resistor 109 (second emission intensity adjustment unit) are provided with a variable resistor that can be adjusted by the special tool. The adjustment range of the detection sensitivity is set to be narrower than that of the devices 54 and 54a (sensitivity adjustment unit) and the variable resistor 108 (the emission intensity adjustment unit), so that the adjustment of the detection sensitivity and the emission intensity in the game hall cannot be performed at all. In addition, since the adjustment range of the detection sensitivity and the emission intensity at the game arcade side is reduced, there is an advantage that it is not possible to perform the adjustment to such an extent that an injustice or a malfunction occurs.

In the first embodiment described above,
Although the sealing cover 70 that seals only the sensitivity adjustment unit has been described as an example of a sealing member that cannot be operated unless it is broken, for example, the protective cover 60 that covers the emission control board 50 is regarded as a sealing member. You may. In this case, the protective cover body 60 may be fixed by a fixing means such as a one-way screw 77, or the first fixed portion and the second fixed portion may be formed integrally with the protective cover body 60. When the protective cover body 60 is regarded as a sealing member, the sealing cover insertion opening 64 does not need to be opened, and the operation opening 63 is also provided on the emission control board 50 by the second sensitivity adjustment unit. This is necessary when the second sensitivity adjustment unit is not provided. Thus, the following invention can be considered as an invention grasped when the protective cover body 60 that covers the emission control board 50 is regarded as a sealing member.

(1) A ball game machine equipped with a ball launching device that launches a ball in response to a detection signal from a touch sensor circuit that detects whether or not the player has touched the contact portion.

Before shipment, the sensitivity adjustment unit is adjusted so as to have an appropriate detection sensitivity, and then the sensitivity adjustment unit is sealed with a protective cover body (sealing member) and shipped in the sealed state. In such a configuration, the sensitivity adjustment unit cannot be operated, so that the detection sensitivity can be properly adjusted, and after shipment, it is not possible to perform the adjustment of the detection sensitivity that causes fraud or malfunction. Effects can be achieved. (2) The emission control board is provided with a second sensitivity adjustment unit that is not sealed differently from the sensitivity adjustment unit sealed by the protective cover body (sealing member), and the second sensitivity adjustment unit is provided. Since the adjustment of the detection sensitivity is set to be narrower than that of the sensitivity adjustment unit sealed by the protective cover body (sealing member), it is possible to eliminate a problem that the adjustment of the detection sensitivity in the game hall cannot be performed at all. At the same time, since the adjustment range of the detection sensitivity on the game arcade side is reduced, there is an advantage that it is not possible to make adjustments to such a degree as to cause injustice or trouble. In this case, the structure in which the second sensitivity adjustment unit is not sealed by the protective cover body may be a structure in which an operation opening is opened in the protective cover body, or a structure in which the second sensitivity adjustment unit is covered with the protective cover body. A structure that is exposed to the outside without being considered can be considered.

Similarly, when only the emission intensity adjusting section for adjusting the emission intensity is provided on the emission control substrate 50, when the protective cover body 60 covering the emission control substrate 50 is regarded as a sealing member. The invention to be grasped is as follows: (1) In a ball game machine provided with a hit ball launching device for hitting a ball, a launch control board provided with a launch intensity adjusting unit for adjusting the launch intensity of the hit ball launching device is destroyed. Before shipment, after adjusting the emission intensity adjustment unit to have an appropriate emission intensity by sealing with a protective cover body (sealing member) that cannot be operated unless otherwise, the emission intensity adjustment unit is attached to the protection cover body ( It is possible to properly adjust the firing intensity by configuring so that it is not possible to operate the firing intensity adjustment unit in the game arcade by sealing with a sealing member) and shipping in a sealed state. After shipment, a remarkable effect that the emission intensity that causes fraud or malfunction cannot be adjusted can be obtained. (2) The emission control board is provided with a second emission intensity adjustment unit that is not sealed differently from the emission intensity adjustment unit sealed by the protective cover body (sealing member), and the second emission The strength adjustment unit is configured such that the adjustment of the emission intensity is set to be narrower than that of the emission intensity adjustment unit sealed by the protective cover body (sealing member). In addition to being able to eliminate it, there is an advantage that since the range of adjustment of the firing intensity on the game arcade side is reduced, it is not possible to make adjustments to such a degree as to cause injustice or trouble. In this case, as the structure in which the second emission intensity adjustment unit is not sealed with the protective cover body, a structure in which an opening for operation is opened in the protection cover body, or the second emission intensity adjustment unit with the protection cover body is used. A structure that is exposed to the outside without coating is conceivable.

Similarly, when the emission control board 50 is provided with both an emission intensity adjustment section for adjusting the emission intensity and a sensitivity adjustment section for adjusting the detection sensitivity, a protective cover for covering the emission control board 50 is provided. The invention that can be grasped when the body 60 is regarded as a sealing member is as follows: (1) A shot ball that fires a hit ball based on a detection signal from a touch sensor circuit that detects whether or not a player has touched a contact portion. In a ball game machine equipped with a device, a firing control board provided with a sensitivity adjusting unit for adjusting the detection sensitivity of the touch sensor circuit and a firing intensity adjusting unit for adjusting the firing intensity of the hit ball firing device cannot be operated unless destroyed. Before the shipment, the sensitivity adjustment unit and the emission intensity adjustment unit are adjusted to have appropriate detection sensitivity by being sealed with the protective cover body (sealing member), and then the sensitivity adjustment unit is adjusted. In addition, the emission intensity adjustment unit is sealed with a protective cover body (sealing member), and is shipped in the sealed state so that the sensitivity adjustment unit and the emission intensity adjustment unit cannot be operated in the game arcade. Thereby, at the time of shipment, the detection sensitivity and the emission intensity can be properly adjusted, and after shipment, the remarkable effect that the detection sensitivity and the emission intensity that cause injustice or malfunction cannot be adjusted. Can play. (2) a second sensitivity adjustment unit and a second sensitivity adjustment unit that are not sealed differently from the sensitivity adjustment unit and the emission intensity adjustment unit sealed by the protective cover body (sealing member);
The second sensitivity adjustment unit and the second emission intensity adjustment unit are provided.
The emission intensity adjustment unit of the present invention, in which the detection sensitivity and the adjustment of the emission intensity are set to be narrower than the sensitivity adjustment unit and the emission intensity adjustment unit that are sealed by the protective cover body (sealing member), It is possible to eliminate the disadvantage of not being able to adjust the detection sensitivity and emission intensity at all, and to reduce the adjustment range of the detection sensitivity and emission intensity at the game arcade, so that it is possible to make adjustments to the extent that injustice or inconvenience occurs. There is an advantage that you can not. In this case, the structure in which the second sensitivity adjustment unit and the second emission intensity adjustment unit are not sealed by the protective cover body may be a structure in which an operation opening is opened in the protective cover body, or a structure in which the protective cover body is opened. A structure in which the second sensitivity adjustment unit and the second emission intensity adjustment unit are exposed to the outside without being covered can be considered.

While the embodiment of the present invention has been described above, in the above-described embodiment, the sensitivity adjustment unit (variable resistor 5) that can be set and operated on the firing control board 50 at the game arcade side.
Although 5) is provided, a configuration in which a sensitivity adjustment unit that can be set and operated on the game arcade side may not be provided. Further, the sealing cover 7 as the sealing member described in the above embodiment.
Although 0 (or the protective cover body 60) is formed of a synthetic resin, it may be formed of another material (for example, metal or the like). However, when composed of synthetic resin,
There is an advantage that it is easier to observe whether or not the inside is made of a transparent synthetic resin that can be visually recognized.

In the above-described embodiment, the variable resistors 108 and 109 for changing the rotation speed of the stepping motor 23 have been described as an example of the emission intensity adjustment unit. If the adjustment is performed mechanically, the mechanical emission intensity adjustment mechanism is sealed with a sealing member, or the mechanical emission intensity adjustment mechanism cannot be operated unless a special tool is used. But it is good. In a hitting ball launching device in which this mechanical launching intensity adjusting mechanism is used, when there is an adjusting mechanism for sealing and an adjusting mechanism for non-sealing, the adjusting mechanism for sealing is used in the same manner as in the above-described embodiment. It is desirable that the adjustment range be set to be wider than that of the unsealed adjustment mechanism. Further, the hit ball launching device may be one in which a mechanical adjustment mechanism and an electrical adjustment unit can coexist.
Also in this case, it is desirable to seal the one with a wider adjustment range.

Further, in the case of the first embodiment described above,
Although the one which can be resealed only once by providing the cutting portion 73 is shown, the one which cannot be resealed may be used, or the one which can be resealed two or more times may be used. Further, a combination of the first embodiment and the second embodiment may be provided with a sensitivity adjustment unit which can be operated only by a special tool inside the sealing member.

[0065]

As apparent from the above description, according to the first aspect of the present invention, a ball is hit by a detection signal from a touch sensor circuit for detecting whether or not the player has touched the contact portion. In a ball game machine provided with a hit ball launching device, a sensitivity adjustment unit for adjusting the detection sensitivity of the touch sensor circuit is sealed with a sealing member that cannot be operated unless destroyed. With this configuration, before shipment, after adjusting the sensitivity adjustment unit to have an appropriate detection sensitivity, the sensitivity adjustment unit is sealed with a sealing member, and the product is shipped in a sealed state. Thus, the sensitivity adjustment unit cannot be operated in the game arcade. For this reason, at the time of shipment, appropriate adjustment of the detection sensitivity is possible, and after shipment,
A remarkable effect that it is not possible to adjust the detection sensitivity that causes fraud or a problem can be achieved.

Further, in the invention according to claim 2, the sealing member is a sealing cover which covers the sensitivity adjusting section,
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 sensitivity adjustment section can be operated on the playing field side, and then the second fixing section can be resealed by fixing the second fixing section with the fixing means. Sometimes, an opportunity to adjust the detection sensitivity only once can be provided. In this case, since the cut portion is cut, if the detection sensitivity after adjustment is not appropriate, by observing the cut portion, it is possible to determine whether the problem was intentionally or mistakenly performed. The judgment can be made easily.

According to the third aspect of the present invention, the touch sensor circuit includes a second sensitivity adjuster which is not sealed unlike the sensitivity adjuster which is sealed by the sealing member. The sensitivity adjustment section 2 is configured so that the adjustment range of the detection sensitivity is set to be narrower than the sensitivity adjustment section sealed by the sealing member, thereby eliminating the disadvantage that the adjustment of the detection sensitivity in the game hall cannot be performed at all. While you can
Since the range of adjustment of the detection sensitivity on the game arcade side is reduced, there is an advantage that it is not possible to make an adjustment to the extent that a fraud or a problem occurs.

According to the fourth aspect of the present invention, there is provided a ball-ball game machine provided with a ball-ball launching device for hitting a ball with a detection signal from a touch sensor circuit for detecting whether or not the player has touched the contact portion. , Wherein the sensitivity adjustment unit for adjusting the detection sensitivity of the touch sensor circuit cannot be adjusted unless a special tool is used. With this configuration, before shipment, the sensitivity adjustment unit is adjusted with a special tool so as to have an appropriate detection sensitivity, and shipped in the adjusted state. The unit is configured so that it cannot be operated. For this reason, at the time of shipment, the detection sensitivity can be appropriately adjusted, and after shipment, a remarkable effect that the detection sensitivity that causes fraud or a defect cannot be adjusted can be obtained.

Further, in the invention of claim 5, the touch sensor circuit is different from the sensitivity adjuster which can be adjusted by the special tool, and can be adjusted without using a special tool. A sensitivity adjustment unit is provided, and the second sensitivity adjustment unit is configured to adjust the detection sensitivity in the game arcade by setting the detection sensitivity adjustment range narrower than the sensitivity adjustment unit that can be adjusted by the special tool. There is an advantage in that it is possible to eliminate the adverse effects that cannot be made at all and to reduce the adjustment range of the detection sensitivity at the game arcade side, so that it is not possible to make adjustments to the extent that injustice or trouble occurs.
