DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine capable of adjusting the firing force of a hit ball of a hit ball firing device according to the amount of rotation of a firing force adjusting member.

[Prior art]

2. Description of the Related Art Conventionally, a bullet having a structure in which the firing force of a hit ball is adjusted by adjusting the biasing force of a hitting rod spring of a hitting ball firing device in accordance with the amount of rotation of a turning operation member (firing force adjusting member) of the hitting ball firing operation device. Ball game machines are offered on the market. In such a ball game machine, in order for a player to maintain a desired firing force of a hit ball, the turning operation member is kept at a constant turning amount against the urging force of the hitting ball spring. There is a problem that if the game is played for a long time, the degree of fatigue increases. Then, in order to reduce this fatigue, a foreign object such as a coin or a match stick is forcibly inserted into a slight gap between the rotation operation member and a gripping member supporting the rotation operation member, thereby fixing the rotation operation member. The player who plays the game does not leave behind, and therefore, the turning operation of the turning operation member cannot be performed smoothly in a short period of time, or the turning operation member and its peripheral portion are other members. However, there is a problem in that it becomes full of scratches in a short period of time. In order to solve such a problem, the applicant of the present invention has previously proposed in Patent Application Nos. 1-3553 and 1-26453 a method for fixing a rotating operation member.

[Problems to be solved by the invention]

In each of the two inventions described above, in order to fix the turning operation member at an arbitrary turning position, power is continuously supplied to an electric device such as an electromagnet during the fixing period. In addition, there is a problem that the electric device generates heat when the game is played for a long time, and the heat generated easily causes the electric device to break down. The present invention has been made in view of the above problems,
An object of the present invention is to provide a ball-and-ball game machine having a structure for fixing a firing force adjusting member that is economical even when a long-time game is played continuously and is hard to break down.

[Means for Solving the Problems]

In order to achieve the above object, a ball game machine according to the present invention is characterized in that the firing force of a hitting ball of a hit ball firing device can be adjusted according to the rotation operation amount of a firing force adjusting member, A support member for rotatably supporting the member, and provided between a side surface of the firing force adjusting member and a side surface of the supporting member, away from a rotation center axis of the firing force adjusting member, and always between the side surfaces thereof. A frictional force applying member for applying a frictional force, and frictional force canceling means for canceling a frictional force between the support member and the firing force adjusting member by the frictional force applying member based on a predetermined canceling condition. It is characterized by having.

[Action]

Since the side surface distant from the center of the firing force adjusting member and the side surface of the support member rotatably supporting the firing force adjusting member always keep their mutual positions by frictional force by the frictional force applying member, the player When the firing force adjusting member is rotated against the frictional force of the frictional force applying member, the firing force adjusting member is fixed at the operated position. That is, even if the operation of the firing force adjusting member is stopped at this position, the firing force adjusting member is held by the frictional force. Then, when the predetermined release condition is satisfied, the frictional force releasing means operates to release the frictional force between the support member and the firing force adjusting member by the frictional force applying member, so that the firing force adjusting member returns to its original state. Can return to position. Therefore, according to the present invention, the fixing of the firing force adjusting member is always held by a strong frictional force between the side surface of the firing force adjusting member and the side surface of the support member, and the electric force is only released when the fixing is released. Since the frictional force canceling means constituted by the device or the like is operated, it is economical and does not cause a failure due to heat generation.

48 cannot rotate. A second metal plate 53 is fixed to the rear surface of the rotating operation member 48. As described above, the second metal plate 53 comes into contact with the front surface of the clutch plate 46, and the first metal plate 43 and the clutch plate 46 are biased by the springs 36a to 36c provided on the yoke 34. Is urged forward, a frictional force is generated between itself and the clutch plate 46. Of course, at this time, a frictional force is also generated on the side surface between the first metal plate 43 and the clutch plate 46. The springs 36a to 36c, the first metal plate 43, the clutch plate 46,
And the second metal plate 53 constitute a frictional force applying member. A middle gripping member 56 is disposed in front of the rotating operation member 48 as shown in FIG. The middle gripping member 46 supports the rotating operation member 48 so as to be rotatable with respect to the rear gripping member 30 by screwing a screw 57 to the connection columns 32a to 32c from the front thereof. is there. Therefore, the rotation operation member
In this embodiment, the support members for supporting the 48 are the rear grip member 30 and the middle grip member 56. A touch detection plate 58 is provided on the entire outer periphery of the middle gripping member 56. The touch detection plate 58 is a metal member attached over the entire outer periphery of the middle gripping member 56, and detects that the player's hand has touched. One end of the touch wiring 59 that contacts the touch detection plate 58 is fixed to the touch detection plate 58 by the screw 57. The other end of the touch wiring 59 is fixed to a front end of the operation rotation shaft 54 made of a conductive material with a screw. In addition, a front gripping member 60 is provided in front of the middle gripping member 56.
Are detachably attached. In the hitting ball launching operation device 20 configured as described above, the rotating operation member 48 is rotated to operate the rotation shaft.
54 also rotates, and its movement is transmitted to the hitting ball firing device 80 via a rotation transmitting member 62 and an interlocking transmitting member 66 described later, and the firing force of the hitting ball can be adjusted. Then, the second metal plate 53 fixed to the rotating operation member 48 and the first metal plate 43 locked on the gripping member 30 after supporting the rotating operation member 48 are opposed via the clutch plate 46. Since the first metal plate 43 is always urged forward by the springs 36a to 36c, a mutual frictional force is generated. Although necessary, even if the user releases his / her hand from the rotating operation member 48, the rotating operation member 48 is fixed at the rotated position. For this reason, once the turning operation member 48 is adjusted to have a desired elasticity, it can be fixed in a state where a force for holding the turning operation member 48 is unnecessary or hardly needed. On the other hand, when the predetermined release condition is satisfied, the release mechanism 33
Works to release the fixed state of the rotating operation member 48 described above. That is, when a current is supplied to the coil body 40 of the release mechanism 33, the yoke 34 becomes an electromagnet, so that the first metal plate 43
Is sucked against the urging force of the springs 36a to 36c. As a result, a slight gap is formed between the first metal plate 43 and the clutch plate 46, and the frictional force is eliminated, so that the rotating operation member 48 is attached to an urging spring 68 provided on an interlocking transmission member 66 described later. It returns to its original position by the power. In this embodiment, as a cancellation condition, as described later, the selector stops contact with the touch detection plate 58 for a predetermined time (for example,
When one minute elapses, a current is supplied to the coil main body 40. Next, the structure of the back surface of the mounting board 21 will be described mainly with reference to FIG. Fastening screws 29a to 29c are implanted on the left and right sides of the center of the mounting board 21, and the fastening screws 29a
29c as described above, the fastening screw through hole 4a of the front frame 1
4c and through the fastening screw insertion holes 83a to 83c on the side of the hitting ball launching device 80, and are fastened by a fastening member to firmly fix the hitting launching device 20 to the front frame 1. Further, the mounting board 21 includes
The wiring from the front-surface single-use switch 72, the wiring of the handle rotation detector 71 described later, the coil wire 41 of the release mechanism 33, and the touch wiring 64 described later are aligned so as not to protrude outside. The wiring is converged by the wiring convergence cover 73. Then, a terminal member 74 is connected to the leading end of the wiring converged by the wiring convergence cover 73, and is drawn out from the wiring drawing hole 6 of the front frame 1 to the back surface of the front frame 1. As shown in FIG. 1, a bearing member 61 housed in a rear portion of the insertion hole 27 of the support column 26 is loosely fitted and stably supported at a rear portion of the operation rotation shaft 54, In the part, a semicircular rotation transmission member 62 is screwed with a washer 63
Fixed by When the screw 63 with washer is fixed, the touch wiring 64 is also fixed at the same time. Thus, the fact that the hand of the player has touched the touch detection plate 58 is transmitted to the touch detection circuit 96 described later via the touch wiring 59, the operation rotation shaft 54, and the touch wiring 64. In addition, the rotation transmitting member 62 has one end of one end of the cord 65 fixed thereto, and the other end formed with a contact protruding piece 70 with which the actuator of the handle rotation detector 71 contacts. The handle rotation detector 71 provided in association with the rotation transmission member 62 functions as a normally open switch, and the rotation transmission member 62
Is rotated, and when the contact protruding piece 70 and the actuator are not in contact with each other, the motor circuit is closed and the rotation of the hitting motor 99 described later is started. A circular interlocking transmission member 66 is connected to the other end of the rope 65 whose one end is connected to the rotation transmission member 62. The interlocking transmission member 66 is rotatably supported by being fixed to the mounting board 21 with screws. An urging spring 68 is interposed in the interlocking transmission member 66, and constantly biases the interlocking transmission member 66 clockwise as viewed in FIG. That is, the rotation operation member 48 is urged to return to the original position. Further, the interlocking transmission member 66 is formed with a fan-shaped engagement hole 67 about the axis. The engagement hole 67 is 3
When the mounting board 21 and a hitting ball launching device 80 to be described later are opposed to the front frame 1, they are fitted to an engaging rotation member 90 provided on the hitting ball launching device 80 to be described later. ing. Thus, the rotational motion of the rotary operation member 48 of the hit ball launching operation device 20 can be transmitted to the hit ball launching device 80 to adjust the elasticity. The mounting board 21 has a positioning hole 5 of the front frame 1.
Positioning projections 69a, 69b are provided at positions corresponding to a, 5b. Next, the hit ball firing device 80 provided at a position corresponding to the hit ball firing operation device 20 will be described with reference to FIGS. 3 and 4. FIG. The hitting ball launching device 80 has an opening 3 formed in the front frame 1.
And is integrated on a mounting board 81. The mounting substrate 81 is formed of a roughly square metal plate, and includes positioning protrusions 82a, 82b,
Fastening screw insertion holes 83a to 83c and the like are respectively formed or protruded. The positioning projections 82a and 82b correspond to the positioning holes 5a and 5b formed in the front frame 1 as described above, and perform absolute positioning of the hitting ball firing device 80 with respect to the front frame 1. As described above, the fastening screw insertion holes 83a to 83c are also provided on the side of the hit ball launching operation device 20.
29a to 29c are inserted, and the ball launching operation device 20 and the ball launching device 80 are attached to each other so as to clamp the front frame 1 by fastening the nut 84 from behind the mounting substrate 81. It is. Further, the mounting substrate 81 is rotatably supported by a hitting rod 85 for hitting a hitting ball standing by at a firing position 92 of a firing rail 91, and is a biasing spring that applies the elastic force of the hitting rod 85. 86 are also provided. One end of the biasing spring 86 is locked by the drive lever 87, and the other end is locked by the winding member 89. The driving lever 87 is a ball motor that is fixed to the rear side of the mounting board 81.
99 (not shown), which is fixed to a rotating cam 88 fixed to a motor shaft.
85 is reciprocatingly rotated within a predetermined angle range. Since the stroke of the hitting rod 85 is always the same, it is necessary to adjust the urging force of the urging spring 86 in order to adjust the resilience. This is performed as follows. You. That is, the winding member 89 locked to the other end of the biasing spring 86
Is configured to be rotatably engaged with an engagement rotating member 90 that is rotated by engaging with the interlocking transmission member 66, so that the rotating operation member 48 is rotated by the player. As a result, the operation rotation shaft 54, the rotation transmission member 62, the cable
The take-up member 89 is rotated by the interlocking transmission member 66 and the engagement rotation member 90 so as to increase the urging force of the urging spring 86. When the urging force of the urging spring 86 becomes stronger, the striking rod 85
The return momentum to the firing position 92 increases, so that the hit ball can be strongly hit. Therefore, the rotation operation member
By adjusting the amount of rotation of 48, the urging force of the urging spring 86 may be adjusted, and thus the firing force of the hit ball may be adjusted. By the way, the release mechanism 33 provided in the hit ball firing operation device 20 is controlled by a control circuit shown in FIG. To explain this, the player rotates the rotation operation member 48 to rotate the rotation transmission member 62, and thus the handle rotation detector 71 is turned on. The ON signal of the handle rotation detector 71 is used as a set signal for starting the timer 95. Further, when the normal player turns the turning operation member 48, the touch is made by the touch detection circuit 96 because the player is in contact with the touch detection plate 58 attached to the outer periphery of the middle gripping member 56. It is detected and the detection signal is used as a reset signal of the timer 95. Therefore, if the player is in contact with the touch detection plate 58 at the same time as rotating the rotation operation member 48, the timer 95 is not activated. The rotation of the rotation operation member 48 is
As described above, the clutch plate 46 and the first metal plate 43 and the second metal plate 53 stop at the position where they are rotated by the mutual frictional force. Further, the detection signal from the touch detection circuit 96 is used as a set signal of the display drive circuit 98, and therefore, the cover member of the hit ball launch operation device 20 is connected via the display drive circuit 98.
The fixed indicator 25 incorporated in the lamp 24 is turned on, thereby notifying the player that the turning operation member 48 is held at the turning position. By the way, when the player removes his / her hand from the hit ball firing operation device 20, the reset signal from the touch detection circuit 96 is not derived because the contact with the touch detection plate 58 is lost. Then, even if the player releases his / her hand from the hit ball firing operation device 20, the turning operation member 48 is held at the turning position as described above, so the handle turning detector 71 remains ON. .
For this reason, the timer 95 is set and activated, and after a certain time (for example, one minute) has elapsed, a time-up signal is derived. The time-up signal is introduced into the one-shot circuit 97, and a relatively short-time excitation signal is derived from the one-shot circuit 97 to the coil wire 41 of the release mechanism 33. When an excitation signal is sent to the coil wire 41, the yoke 34 becomes an electromagnet, and the first metal plate 43 is attracted against the urging force of the springs 36a to 36c.
The frictional force between the metal plate 43, the clutch plate 46, and the second metal plate 53 disappears, and the rotating operation member 48 returns to the initial position. The time-up signal sends a reset signal to the display drive circuit 39, thereby turning off the process display 25. An example of a specific operation of the control circuit described above is shown in a time chart of FIG. More specifically, in the first half of the time chart, when the turning operation member 48 is turned (ACT), the handle turning detector 71 is turned on, and at the same time, power is supplied to the control circuit. However, at this time, if the player performs a rotating operation without touching the touch detection plate 58, the hit ball motor 99 does not turn on. Also timer
95 is started because a set signal is sent from the handle rotation detector 71 (shaded area). When the timer 95 times out, a one-shot signal is derived from the one-shot circuit 97, and a current is supplied to the coil wire 41 based on the one-shot signal. Then, the rotation operation member 48 returns to the initial position, and the handle rotation detector 71 and the power supply are turned off. On the other hand, in the latter half of the time chart,
This shows a state in which the player touches the touch detection plate 58 while the player 48 is turned, and then stops touching. Then
When the user touches the touch detection plate 58 immediately after the rotation operation of the rotation operation member 48 is started, the activation of the timer 95 is stopped, and the ball driving motor 99 is driven to rotate, so that a game can be performed. Thereafter, when the player releases his hand from the touch detection plate 58,
In the same manner as described above, the timer 95 is started, and after the time is up, the release mechanism 33 operates to return the rotating operation member 48 to the initial position. Although the embodiment has been described above, according to this embodiment, the turning operation member 48 as the firing force adjusting member is rotatably provided on the rear gripping member 30 and the middle gripping member 56 as the support members. At the same time, the first metal plate 43, the clutch plate 46, and the second metal plate so that frictional force always acts between the mutual side surfaces.
Since the 53 is provided, the rotating operation member 48 is held at the rotated position, so that the player does not get tired even after a long game. In addition, since the holding mechanism of the rotating operation member 48 is performed by a mechanical mechanism, power is not consumed while the rotating operation member 48 is held, which is economical and does not cause a failure due to heat generation. Further, when a predetermined time has elapsed after the player has released his / her hand from the operation and firing device 20, the release mechanism 33 operates to reduce the frictional force of the first metal plate 43, the clutch plate 46, and the second metal plate 53. Since the rotation operation member 48 is
Automatically returns to its initial position, so that the next player can adjust the new desired firing force. In the above-described embodiment, the predetermined release condition is that a predetermined time elapses after the touch detection plate 58 is not touched. However, the release may be performed immediately after the contact disappears, or When the remaining amount of the hit ball to be shot is equal to or less than a predetermined amount, or in the case of a type that detects a firing ball or a hit ball, cancels that the output of the firing ball or the hit ball is not within a certain time. It may be a condition. Further, the ball-and-ball game machine may be a so-called card-type ball-and-ball game machine that plays a game by using a card storing ball data, and in this case, the score is equal to or less than a predetermined number. When it becomes, it may be a release condition.

【The invention's effect】

As is apparent from the above description, the ball game machine according to the present invention includes a support member rotatably supporting the firing force adjusting member, and a firing force adjusting member distant from the rotation center axis of the firing force adjusting member. A frictional force applying member provided inside the side surface of the support member and a side surface of the support member and always applying a frictional force between the side surfaces, and a support member by the frictional force applying member based on a predetermined release condition and firing. And frictional force canceling means for canceling the frictional force between the force adjusting member,
The firing force adjusting member is always fixed by strong frictional force, and the frictional force releasing means composed of electrical equipment etc. is operated only when releasing the fixing, so it is economical and failure due to heat is generated. Does not occur.
