Abstract

PROBLEM TO BE SOLVED: To provide a pinball game machine configured such that on the basis of the normal shooting of a game ball with a desired shooting force by predetermined operation, the shooting force is further increased and reduced by other predetermined operation, and further damage or failure unlikely occurs.SOLUTION: When a first gear body 71 and a second gear body 72 are set at a base position for relative rotation, a relative rotation control mechanism engages both gear bodies 71 and 72 to restrict the relative rotation between both gear bodies 71 and 72, and the rotations of a main shooting lever and sub shooting lever are transmitted to a volume controller. When the rotation force in a direction in which the shooting force is increased is applied to the first gear body 71, while the rotation of the second gear body 72 is restricted in a direction in which the shooting force is increased, from the base position for relative rotation, the engagement between the relative rotation control mechanism and the second gear body 72 is released, and the relative rotation of the first gear body 71 is permitted in the direction in which the shooting force is increased.

Description

  The present invention relates to a ball game machine that plays a game by launching a game ball into a game area of a game board.

  Patent Document 1 describes a ball striking force adjusting operation device in which a center gear, an idle gear, and an operator are rotatably attached to a striking force adjusting wheel that is rotatably provided between a base and a head. Has been. The center gear is provided so as to be rotatable on a coaxial line with the hitting force adjusting wheel, and is externally meshed with the idle gear. The operation element is attached to the periphery of the hitting force adjusting wheel so as to be rotatable. The hitting force adjusting wheel is biased by the torsion spring in the decreasing direction of the hitting force, and the operating element is biased by the torsion spring in the direction in which the pressing portion protrudes outward from the outer peripheral end surface of the hitting force adjusting wheel. A volume is attached to the base of the operating device body, and a gear meshing with the center gear is attached to the signal input shaft. A signal having a magnitude proportional to the amount of rotation of the central gear is input from the volume to the launching device, whereby the hitting force is increased or decreased.

  When the hitting force adjusting wheel is rotated in the direction of increasing hitting force against the elasticity of the torsion spring, the turning operation force is transmitted from the operator turning around the center gear to the center gear via the idle gear. As a result, the center gear also rotates in the increasing direction of the hitting force. Also, when the hitting force adjusting wheel is constrained to an arbitrary rotation position and the pressing portion of the operating element is pressed against the elasticity of the torsion spring, the transmission gear portion rotates to change the idle gear from the center gear. The rotational force is transmitted and the center gear rotates in the direction of increasing the hitting force.

JP 2007-143949 A

  In general, in a shooting operation device operated to adjust the launching force of a game ball, when the hitting force adjusting wheel is rotated to the maximum launch position, which is the rotation limit, a sufficient hitting force that does not become excessive is a game. It is given to the sphere.

  However, in the structure of Patent Document 1, since the rotation limit of the operation element in the increasing direction of the hitting force is not particularly set, for example, the hitting force of the operation element is increased while the hitting force adjusting wheel is rotated to the maximum firing position. When it is rotated in the direction, the volume is excessively rotated and an excessive hitting force more than necessary is applied to the game ball.

  Such inconvenience can be avoided by setting the rotation limit of the volume so that excessively high hitting force is not applied to the game ball. In this case, when the volume reaches the rotation limit, the hitting force adjusting wheel and the operation element do not rotate even when receiving the rotational force in the increasing direction of the hitting force.

  However, when the rotation limit of the volume is set as described above, when the player strongly rotates the hitting force adjusting wheel or strongly presses the operation element even though the volume reaches the rotation limit. In addition, an excessive load is applied to the volume, which may cause damage or failure.

  The present invention has been made in view of the above circumstances, and the firing force can be increased or decreased by another predetermined operation on the basis of a state in which a game ball is fired at a desired firing force by a predetermined operation. It is another object of the present invention to provide a ball game machine that is not easily damaged or broken.

  To achieve the above object, the present invention provides a launching device for launching a game ball, a launching force changing unit for changing the launching force of a game ball in the launching device, and a launching operation device for operating the launching force changing unit. The firing operation device includes a base body, a main firing lever, a secondary firing lever, a first gear body, a second gear body, an adjustment gear body, a maximum firing force setting means, and a relative rotation control. And a mechanism.

  The base body is fixed to the ball game machine. The main firing lever is supported by the base body so as to be rotatable about the main rotation axis, and rotates in accordance with an operation from the player. The secondary firing lever is disposed between the base body and the primary firing lever, and is supported by the primary firing lever so as to be rotatable about a secondary rotation axis substantially parallel to the primary rotation axis. The arcuate secondary firing gear portion revolves around the main rotational axis as the main firing lever rotates, and rotates around the secondary rotational axis in response to an operation from the player. The first gear body is disposed between the base body and the main firing lever, and is supported by the base body or the main firing lever so as to be rotatable in the firing force increasing direction and the firing force decreasing direction about the main rotation axis. It has an arcuate shape centering on the rotational axis and an operation gear portion that meshes with the secondary firing gear portion. The second gear body is disposed between the base body and the first gear body, and is supported by the base body or the main firing lever so as to be rotatable in the firing force increasing direction and the firing force decreasing direction around the main rotation axis. It has an arcuate transmission gear portion centered on the main rotational axis. The adjustment gear body is disposed between the base body and the main firing lever, and is supported by the base body so as to be rotatable about an adjustment rotation axis substantially parallel to the main rotation axis, with the adjustment rotation axis as the center. And an adjustment gear portion that meshes with the transmission gear portion, and transmits the rotation of the second gear body to the firing adjustment means. The maximum firing force setting means restricts the rotation limit of the second gear body in the firing force increasing direction to the maximum firing force position.

  The relative rotation control mechanism is provided between the first gear body and the second gear body, and in a state where the first gear body and the second gear body are set at a predetermined basic relative rotation position, Engage with the second gear body to regulate relative rotation between the two gear bodies, and launch the first gear body in a state where the rotation of the second gear body from the basic relative rotational position in the direction of increasing firing force is regulated. When a rotational force in the direction of increasing the force is applied, the engagement with the first gear body or the second gear body is released, and relative rotation in the direction of increasing the firing force of the first gear body with respect to the second gear body is allowed. And when the first gear body is rotated relative to the second gear body from the basic relative rotation position in the firing force increasing direction and the first gear body is applied with a rotational force in the firing force decreasing direction, Allow relative rotation of the first gear body in the direction of decreasing the firing force relative to the two gear bodies, and place both gear bodies in the basic relative rotation position. To return.

  Revolution means rotation around a rotation axis that passes outside of itself, and rotation means rotation around a rotation axis that passes through itself.

  In the above-described configuration, in the initial state where the launch of the game ball is stopped, the main launch lever, the secondary launch lever, the first gear body, the second gear body, and the adjustment gear body are each origin positions that are rotation limits in the firing force decreasing direction. The first gear body and the second gear body are set to the basic relative rotation position.

  The player who starts the game rotates the main firing lever in the initial state in the firing force increasing direction. When the main firing lever rotates, the secondary firing lever does not rotate but revolves around the main rotation axis. Since the auxiliary firing gear portion of the secondary firing lever and the operation gear portion of the first gear body are engaged, the first gear body rotates in the direction of increasing the firing force in conjunction with the rotation of the main firing lever. When the first gear body rotates, the relative rotation control mechanism engages with the first gear body and the second gear body to restrict relative rotation between the two gear bodies, and the second gear body is integrated with the first gear body. Rotate. Since the transmission gear portion of the second gear body and the adjustment gear portion of the adjustment gear body are engaged with each other, the adjustment gear body rotates in the direction of increasing the firing force in conjunction with the rotation of the second gear body, and the firing force changing means. This changes the launch force of the game ball. That is, the player can fire the game ball with a desired launch force by appropriately adjusting the amount of rotation from the origin position of the main launch lever.

  For example, when it becomes necessary to increase the launching power of a game ball in the middle of a game, such as a transition to a game (right-handed game) that requires the launch of a game ball to the right area of the game area, The secondary firing lever may be rotated in the direction of increasing the firing force while maintaining the rotational position of the main firing lever. Since the auxiliary firing gear portion of the secondary firing lever and the operation gear portion of the first gear body are engaged, the first gear body rotates in the direction of increasing the firing force in conjunction with the rotation of the secondary firing lever. When the first gear body rotates, the relative rotation control mechanism engages with the first gear body and the second gear body to restrict relative rotation between the two gear bodies, and the second gear body is integrated with the first gear body. Rotate. Since the transmission gear portion of the second gear body and the adjustment gear portion of the adjustment gear body are engaged with each other, the adjustment gear body rotates in the direction of increasing the firing force in conjunction with the rotation of the second gear body, and the firing force changing means. This changes the launch force of the game ball. In other words, the player can increase the launching force of the game ball by operating the secondary firing lever while maintaining the main firing lever at a desired rotational position.

  The rotation limit of the second gear body in the direction of increasing the firing force is restricted to the maximum firing force position by the maximum firing force setting means. That is, the second gear body does not rotate in the direction of increasing the firing force beyond the maximum firing force position, and an excessive load is not applied to the firing force changing means.

  In a state where the second gear body has reached the maximum firing force position, the player operates the main firing lever or the secondary firing lever in the firing force increasing direction, and the rotational force in the firing force increasing direction is applied to the first gear body. Then, the relative rotation control mechanism releases the engagement with the first gear body or the second gear body, and allows the relative rotation of the first gear body relative to the second gear body in the direction of increasing the firing force. 1 gear body idles. Therefore, an excessive load in the firing force increasing direction input to the first gear body or the second gear body can be mitigated by the relative rotation of the first gear body and the second gear body.

  When returning the first gear body, which has been rotated relative to the second gear body from the basic relative rotational position in the firing force increasing direction, to the basic relative rotational position, the player moves the main firing lever or the secondary firing lever in the firing force decreasing direction. It is only necessary to operate to apply a rotational force in the direction of decreasing the firing force to the first gear body. When a rotational force in the firing force decreasing direction is applied to the first gear body, the relative rotation control mechanism allows the relative rotation of the first gear body in the firing force decreasing direction with respect to the second gear body to allow both gear bodies. To the basic relative rotation position.

  The relative rotation control mechanism may include a transmission guide, a transmission guide urging means, a locking projection, an engagement recess, and an inclined guide surface.

  The transmission guide is supported by one of the first gear body and the second gear body in a state in which the transmission guide is slidable along the main rotation axis and relative rotation with respect to the one gear body is restricted. The transmission guide biasing unit biases the transmission guide toward the other gear body of the first gear body and the second gear body. The engaging recess and the inclined guide surface are provided on one member of the transmission guide and the other gear body. The locking protrusion is provided on the other member of the transmission guide and the other gear body, and is engaged with the engagement recess by the urging force of the transmission guide urging means in a state where both gear bodies are set to the basic relative rotation position. Match. Engagement between the locking projection and the engaging recess restricts relative rotation of both gear bodies. The inclined guide surface has an arc shape centered on the main rotation axis and extends in the firing force increasing direction from the engaging recess so as to be inclined toward the other member. When the rotational force in the firing force increasing direction is applied to the first gear body in a state in which the rotation of the second gear body in the firing force increasing direction from the basic relative rotation position is restricted, the locking projections bias the transmission guide. Riding on the inclined guide surface from the engaging recess against the urging force of the means, relative rotation of the first gear body relative to the second gear body in the direction of increasing the firing force is allowed. When the first gear body is rotated relative to the second gear body from the basic relative rotational position in the firing force increasing direction and a rotational force in the firing force decreasing direction is applied to the first gear body, The locking projection slides toward the engaging recess by the urging force of the transmission guide urging means and the inclination of the inclined guide surface.

  In the above configuration, in the state where the first gear body and the second gear body are set at the basic relative rotation position, the locking protrusion provided on the other member of the transmission guide and the other gear body is provided with the transmission guide. The urging force of the urging means engages with an engagement recess provided in one member of the transmission guide and the other gear body.

  In a state where the second gear body has reached the maximum firing force position, the player operates the main firing lever or the secondary firing lever in the firing force increasing direction, and the rotational force in the firing force increasing direction is applied to the first gear body. Then, the locking projection climbs on the inclined guide surface from the engaging recess against the urging force of the transmission guide urging means, and relative rotation of the first gear body in the direction of increasing the firing force with respect to the second gear body is allowed. Then, the first gear body is idled.

  In order to return the first gear body, which has rotated relative to the second gear body from the basic relative rotation position in the firing force increasing direction, to the basic relative rotation position, the player moves the main firing lever or the secondary firing lever in the firing force decreasing direction. By operating and applying a rotational force in the firing force decreasing direction to the first gear body, the locking protrusion on the inclined guide surface is engaged with the recessed portion by the urging force of the transmission guide urging means and the inclination of the inclined guide surface. The two gear bodies return to the basic relative rotation position.

  The firing operation device may further include a minimum firing force setting means for restricting the rotation limit of the second gear body in the firing force decreasing direction to the origin position where the launch of the game ball stops.

  In the above configuration, the rotation limit of the second gear body in the direction of decreasing the firing force is restricted to the origin position by the minimum firing force setting means. Therefore, when returning the first gear body, which has rotated relative to the second gear body from the basic relative rotation position in the firing force increasing direction, to the basic relative rotation position, the player reduces the main firing lever or the secondary firing lever. Even if both gear bodies do not return to the basic relative rotation position simply by operating in the direction, a rotational force in the direction of decreasing the firing force is applied to the first gear body after returning the second gear body to the origin position. Thus, both gear bodies can be reliably returned to the basic relative rotational position.

  According to the present invention, it is possible to increase or decrease the firing force by another predetermined operation on the basis of the state where the game ball is fired at a desired firing force by a predetermined operation, and damage or failure occurs. A difficult ball game machine can be provided.

  An embodiment of the present invention will be described with reference to the drawings. In the following description, the player side is the front, the ball game machine side is the rear, and the left and right viewed from the front are the left and right directions. Further, the firing force increasing direction of the main firing lever, the first gear body, and the second gear body is clockwise (clockwise) when viewed from the front, and the firing force increasing direction of the auxiliary firing lever and the volume gear member is counterclockwise. (Counterclockwise).

As shown in FIGS. 1 to 4, the ball game machine (pachinko machine) of the present embodiment is built in a game machine main body (not shown) and launches a game ball into a game area (not shown) of the game board. A launcher (not shown), and a volume (variable resistor: launching force changing means) 1 for changing the firing force of a game ball in the launching device by increasing or decreasing the value of a current supplied to a drive source such as a motor of the launching device; And a firing operation device 100 for operating the volume 1. The player operates the launch operation device 100 to start and stop the launch of the game ball and adjust the launch force.
[Schematic structure of launch control device]
The firing operation device 100 includes a base body 2 fixed to the gaming machine body, a cover 3 attached to the front side of the base body 2, and a main firing lever (handle ring) disposed between the base body 2 and the cover 3. 4).

  The base body 2 includes a cylindrical base portion 21 fixed to the gaming machine body, a housing portion 22 that expands in a tapered shape from the base portion 21 toward the front, and a front-rear direction in the vicinity of the boundary between the base portion 21 and the housing portion 22 And a base plate portion 20 substantially orthogonal to each other. The base plate portion 20 is integrally provided with a central rotation shaft 80 extending forward at the approximate center of the housing portion 22. As will be described later, the central rotary shaft 80 and the cover-side bearing portion 25 of the cover 3 rotate about the main rotary shaft 32 of the main firing lever 4 about the main rotary shaft 81 (axial center of the central rotary shaft 80). Support freely. The cover 3 is formed in a dome shape whose diameter increases toward the rear, and covers the front of the accommodating portion 22 of the base body 2.

  In the inner region of the cover 3, a main spring 5 that urges the main firing lever 4 toward the origin position (in a firing force decreasing direction), a spring holding member 6 disposed inside the main spring 5, and the main firing lever 4 And a touch sensor 7 for detecting the contact of the player's hand.

  In the inner region partitioned by the main firing lever 4 and the base body 2, a sub-firing lever 9 having a sub-firing gear portion 8 and a sub-firing lever 9 that urges the sub-firing lever 9 toward the home position side (firing force decreasing direction). A first gear body (one gear body) 71 having a spring 10 and an operation gear portion 11 meshing with the auxiliary firing gear portion 8, a relative rotation control mechanism 70 (see FIG. 5), and the rotation of the first gear body 71. A second gear body (the other gear body, one member) 72 having a transmission gear portion 15 that transmits to the volume 1 side via the relative rotation control mechanism 70 and a rotary type fixed to the base portion 21 of the base body 2 A volume gear body (adjustment gear body) 19 that is fitted to the rotary shaft member 18 of the volume 1 and rotates integrally with the rotary shaft member 18, and a launch stop switch 13 and a launch stop button 14 that stop the launch of the game ball are provided. Is provided.

  The accommodating portion 22 of the base body 2 is provided with a plurality of cylindrical bosses 23 extending forward from the base portion 21 side, and a portion corresponding to the boss 23 on the rear surface of the cover 3 (the back surface of the dome-shaped portion). Is formed with a fitting shaft portion 24 protruding rearward. The cover 3 is fixed to the front side of the base body 2 by inserting and fitting the rear end portion of the fitting shaft portion 24 into the front end portion of the cylindrical boss 23. A cylindrical cover-side bearing portion 25 extending rearward is formed in the approximate center of the rear surface of the cover 3.

  The main firing lever 4 integrally includes a substantially cylindrical cylindrical portion 27 having a short axial length and a substantially disc-shaped bottom plate 28 provided inside the cylindrical portion 27. The portion is provided with an operated portion 29 for a player to hold and operate with a finger.

  Two long holes 31 are formed in the bottom plate 28 of the main firing lever 4. In a state where the cover 3 is fixed to the base body 2, the fitted boss 23 and the fitting shaft portion 24 pass through each of the long holes 31. The long hole 31 is formed in an arc shape centering on a main rotation axis 81 that is a rotation center of the main firing lever 4 (a center line of the cover side bearing portion 25 and a main rotation shaft 32 described later). The rotatable range of the main launch lever 4 depends on the length of the long hole 31 (both edges in the arc direction) from the origin position where the launch of the game ball stops to the maximum launch force position where the launch force of the game ball is maximized. Regulated to range. That is, the long hole 31 and the boss 23 of the main firing lever 4 function as a stopper that restricts the rotation range of the main firing lever 4. The operated portion 29 is viewed from the front in a state where the main firing lever 4 is set to the origin position so as to be positioned between the thumb and the index finger of the right hand of the player holding and operating the main firing lever 4. Projecting in a substantially triangular shape in a direction intersecting with the main rotation axis 81 (from the outer periphery of the cylindrical portion 27 to the upper left of the main rotation axis 81).

  When the main firing lever 4 rotates in the direction of decreasing the firing force and returns to the vicinity of the origin position, the launch of the game ball stops. Further, the player can maximize the firing force of the game ball by operating the secondary firing lever 9 without rotating the main firing lever 4 to the maximum firing force position.

  A cylindrical main rotary shaft 32 extending forward is integrally formed at the center of the front surface of the bottom plate 28 of the main firing lever 4. When the front end portion of the main rotating shaft 32 is rotatably inserted into the cover-side bearing portion 25, and the front end portion of the central rotating shaft 80 of the base body 2 is rotatably inserted into the main rotating shaft 32, main firing is performed. The lever 4 is rotatably held with respect to the base body 2 and the cover 3.

  The spring holding member 6 is disposed around the main rotating shaft 32 behind the cover side bearing portion 25. The spring holding member 6 has a cylindrical shape with a flange on the rear end side, and the main rotating shaft 32 passes through the inside of the spring holding member 6. The spring holding member 6 is inserted inside the main spring 5 that is a torsion coil spring, and restricts the rearward movement of the main spring 5 by a flange.

  One end of the main spring 5 is locked to the cover 3, and the other end is locked to the main firing lever 4, so that the main firing lever 4 operated from the origin position to the maximum firing position is moved to the origin position side ( When the player releases his hand from the main firing lever 4, the main firing lever 4 returns to the origin position side by the biasing force of the main spring 5.

  The secondary firing lever 9 is disposed behind the rear surface on the outer edge side of the bottom plate 28 of the primary firing lever 4. The secondary firing lever 9 is provided with a secondary firing gear portion 8, a secondary operation portion 34, and a bearing hole 35. By inserting the auxiliary rotating shaft 36 formed on the bottom plate 28 of the main firing lever 4 into the bearing hole 35, the auxiliary firing lever 9 is rotatably supported by the main firing lever 4.

  The rotation center (sub rotation axis) 82 of the secondary firing lever 9 and the rotation center (main rotation axis) 81 of the main firing lever 4 are set substantially parallel to each other, and the secondary firing lever 9 is located outside the main rotation axis 81. Has been placed. As a result, the secondary firing lever 9 revolves around the main rotational axis 81 as the main firing lever 4 rotates, and rotates around the secondary rotational axis 82 according to the operation from the player.

  The sub-operated portion 34 protrudes outward from a notch (not shown) of the cylindrical portion 27 of the main firing lever 4 at the origin position. By pressing down the sub-operated portion 34 at the origin position toward the inside of the cylindrical portion 27 of the main firing lever 4, the sub-launching lever 9 rotates from the origin position to the maximum firing force position.

  The periphery of the bearing hole 35 of the secondary firing lever 9 is formed in a cylindrical shape protruding forward, and the secondary spring 10 that is a torsion coil spring is disposed around the cylindrical portion. One end of the secondary spring 10 is locked to the main firing lever 4 and the other end is locked to the secondary firing lever 9, thereby biasing the secondary firing lever 9 toward the origin position (in the firing force decreasing direction). When the player releases the pressing of the secondary firing lever 9, the secondary firing lever 9 returns to the origin position side by the biasing force of the secondary spring 10. When the secondary firing lever 9 returns to the origin position, the base of the secondary firing gear portion 8 of the secondary firing lever 9 comes into contact with one boss 23, and the rotation of the secondary firing lever 9 in the firing force decreasing direction is restricted. That is, this one boss 23 functions as a stopper on the origin position side of the sub-fire lever 9.

  No special stopper is provided on the maximum firing force position side (launching force increasing direction) of the secondary firing lever 9, and the player pushes the secondary operation part 34 into the cylindrical part 27 with a finger by a normal pushing operation. The state is the maximum firing position of the secondary firing lever 9. When the sub-operating portion 34 of the sub-launching lever 9 is forcibly pushed into the inside of the cylindrical portion 27 from the maximum firing force position, the sub-operating portion 34 comes into contact with the one boss 23 and the sub-operating portion 34 is It cannot be pushed in more than this, and the contact position with this boss 23 becomes the rotation limit of the firing force increasing direction of the secondary firing lever 9. A stopper may be provided that restricts the rotation limit of the secondary firing lever 9 in the direction of increasing the firing force before coming into contact with the boss 23.

  The secondary firing gear portion 8 has an arc shape centered on the secondary rotation axis 82 and is formed as a tooth portion of a substantially sector-shaped sector gear corresponding to the rotatable range of the secondary firing lever 9. As will be described later, the auxiliary firing gear portion 8 meshes with the operation gear portion 11 of the first gear body 71.

  The notch part from which the sub-operating part 34 of the sub-firing lever 9 projects is formed on the side surface of the cylindrical part 27 of the main firing lever 4 on the side of the firing force decreasing direction of the operated part 29. With such an arrangement, the player can easily push the sub-operating portion 34 with the thumb while the main firing lever 4 is rotated with the thumb of the right hand placed in the direction of decreasing the firing force of the operated portion 29. it can.

  A cutout portion 26 through which the firing stop button 14 is inserted is formed on the outer peripheral edge on the left side of the front end of the housing portion 22 of the base body 2. One end portion of the firing stop button 14 is rotatably supported by a button shaft portion 37 projecting from the housing portion 22 of the base body 2 at the upper right of the notch portion 26, and the other end portion of the firing stop button 14 is supported by the notch portion 26. Protrudes from the outside. Between the firing stop button 14 and the base body 2, urging means (not shown) for urging the firing button 14 in the left rotation direction (the direction in which the other end projects) is provided. When the firing stop button 14 is pressed from the launch permitting position to the launch stop position against the biasing force of the biasing means, the launch stop switch 13 provided in the housing portion 22 switches from launch permit to launch prohibition, and the launch is stopped. A firing stop signal is output from the switch 13 to the firing control unit of the launching device. While the launch stop button 14 is maintained at the launch stop position, the launch stop switch 13 continuously outputs a launch stop signal, and the launching device that has received the launch stop signal stops launching the game ball.

  The volume gear body 19 includes a through hole 61 into which the rotary shaft member 18 of the volume 1 is inserted, a volume gear portion 52, and a volume regulated portion 62 for regulating the rotation range of the volume gear body 19. The volume gear body 19 is supported by the base body 2 so as to be rotatable about an adjustment rotation axis 83 substantially parallel to the main rotation axis 81. The volume gear portion 52 has an arc shape centered on the adjustment rotation axis 83 and is formed as a tooth portion of a sector gear corresponding to the rotation range of the volume gear body 19, and is transmitted to the second gear body 72 as will be described later. The rotation of the second gear body 72 is transmitted by meshing with the gear portion 15.

The volume restricted portion 62 extends outward from the main body of the volume gear body 19 along the radial direction from the rotation center of the volume gear body 19. The volume gear body 19 is restricted from rotating by contacting the volume restricting members 63 formed at two locations on the bottom of the accommodating portion 22. The rotation range restricted by the volume restricting member 63 is set slightly wider than the rotation range restricted by the transmission gear portion 15, and the volume restricted portion 62 does not contact the volume restricting member 63 in a normal use state. The volume regulated portion 62 and the volume regulating member 63 are used to determine the rotation angle of the volume gear body 19 when the volume gear body 19 is engaged with the transmission gear portion 15 when the firing operation device 100 is assembled. .
[First gear body, second gear body and relative rotation control mechanism]
As shown in FIG. 5 to FIG. 11, the first gear body 71 has a rear narrow inner diameter part (rear inner diameter part) 71 a and a front larger inner diameter part (front inner diameter part) 71 b. It is formed in a cylindrical shape. The second gear body 72 is formed in a substantially cylindrical shape having substantially the same outer diameter as that of the first gear body 71 and having an inner diameter portion 72b having substantially the same diameter as the rear inner diameter portion 71a of the first gear body 71. Yes. In the state where the second gear body 71 is arranged behind the first gear body 71, the rear inner diameter portion 71 a of the first gear body 71 and the inner diameter portion 72 a of the second gear body 72 are connected to the center of the base body 2. The rotating shaft 80 is inserted. Thereby, both the gear bodies 71 and 72 are supported by the base body 2 and the main firing lever 4 so as to be rotatable in the firing force increasing direction and the firing force decreasing direction around the main rotation axis 81. The longitudinal movement of both gear bodies 71 and 72 is restricted by the front surface of the base plate portion 20 of the base body 2 and the rear surface of the main rotating shaft 32 of the main operation lever 4. One or both of the gear bodies 71 and 71 may be supported only by the base body 2 or may be supported only by the main firing lever 4.

  On the outer periphery of the first gear body 71, an arcuate operation gear portion 11 centering on the main rotation axis 81 is provided, and the operation gear portion 11 meshes with the sub firing gear portion 8 of the sub operation lever 9. On the outer periphery of the second gear body 72, an arcuate transmission gear portion 15 centering on the main rotation axis 81 is provided, and the transmission gear portion 15 meshes with the adjustment gear portion 52 of the volume gear body 19. At the front portion of the first gear body 71, four notched slide grooves 78 extending rearward from the front end of the first gear body 71 are formed.

  A base-side upper limit stopper (maximum firing force setting means) 91 projects forward from the base plate portion 20 of the base body 2, and a gear-side stopper (maximum firing force setting means) 92 is provided on the outer periphery of the second gear body 72. Is protruding. When the gear-side stopper 92 abuts on the base-side upper limit stopper 91, the limit of rotation of the second gear body 72 in the firing force increasing direction is restricted to the maximum firing force position. That is, the base-side upper limit stopper 91 and the gear-side stopper 92 function as maximum firing force setting means for restricting the rotation limit of the second gear body 72 in the firing force increasing direction to the maximum firing force position.

  A relative rotation control mechanism 90 is provided between the first gear body 71 and the second gear body 72. The relative rotation control mechanism 90 includes a transmission guide (the other member) 73, a coil spring (transmission guide biasing means) 74, a locking projection 75, an engagement recess 76, and an inclined guide surface 77. The state is switched between a state in which relative rotation between the gear bodies 71 and 72 is restricted and a state in which the relative rotation is allowed.

  The coil spring 74 is accommodated in the rear inner diameter portion 71b of the first gear body 71 in a state where the central rotating shaft 80 is inserted through the inner diameter portion thereof.

  The transmission guide 73 integrally includes a guide plate portion 84, four slide engagement portions 85, and two locking projections 75. The guide plate portion 84 has an outer diameter that is slightly smaller than the front inner diameter portion 71b of the first gear body 71 and has an inner diameter portion 73b that is substantially the same diameter as the rear inner diameter portion 71a of the first gear body 71. It is formed in a cylindrical shape.

  The four slide engaging portions 84 are arranged corresponding to the four slide grooves 78 of the first gear body 71, have a slightly smaller circumferential width than the slide groove 78, and Projects radially outward from the outer periphery. With the central rotary shaft 80 inserted into the rear inner diameter portion 71 a of the first gear body 71, the central rotary shaft 80 is inserted into the inner diameter portion 73 a of the guide plate portion 84 and slides into the slide groove portion 78 of the first gear body 71. When the engaging portion 84 is inserted, the slide engaging portion 84 engages with the slide groove portion 78, and the guide plate portion 84 is accommodated and supported by the front inner diameter portion 71 b of the first gear body 71. The engagement of the slide engagement portion 84 with the slide groove portion 78 is a state in which the relative rotation between the first gear body 71 and the transmission guide 73 is restricted, and the front and rear direction of the transmission guide 73 (the direction along the main rotation axis 81). ) Slide movement is allowed. Note that the positions of the gear bodies 71 and 72 in the front-rear direction are not changed by the sliding movement of the transmission guide 73 and are maintained at predetermined positions.

  The two locking projections 75 are arranged so as to face each other with the inner diameter portion 73 a interposed therebetween, and project forward from the front surface of the transmission guide 73. The front end portion of the locking projection 75 is formed in a conical or hemispherical shape that tapers forward.

  The transmission guide 73 is inserted from the front into the rear inner diameter portion 71 b in a state where the coil spring 74 is accommodated in the rear inner diameter portion 71 b of the first gear body 71, and the coil spring 74 is inserted into the inner diameter portion 72 a of the second gear body 72. In the state where the transmission guide 73 is inserted into the rear inner diameter portion 71, the central rotary shaft 80 is inserted. The front end of the coil spring 74 contacts the rear surface of the guide plate portion 84 of the transmission guide 73, and the coil spring 74 urges the transmission guide 73 forward (to the second gear body 72 side).

  On the rear surface of the second gear body 72, two engagement recesses 76 and two inclined guide surfaces 77 are formed corresponding to the locking protrusions 75 of the transmission guide 73, respectively. Each locking projection 75 of the transmission guide 73 is engaged with the corresponding engaging recess 76 by the urging force of the coil spring 74 in a state where the gear bodies 71 and 72 are set at a predetermined basic relative rotational position ( (See FIG. 10). Engagement between the locking protrusion 75 and the engaging recess 76 restricts relative rotation of the two gear bodies 71 and 72.

  In a state where both the gear bodies 71 and 72 are set at the basic relative rotation position, only the main firing lever 4 is moved from the origin position in the direction of increasing the firing force without being pushed down while the auxiliary firing lever 9 is maintained at the origin position. When the rotary operation is performed, the secondary firing lever 9 does not rotate but revolves around the main rotation axis 81, and the secondary firing gear portion 8 of the secondary firing lever 9 and the operation gear portion 11 of the first gear body 71 mesh with each other. Accordingly, the first gear body 71 and the second gear body 72 rotate in the direction of increasing the firing force in conjunction with the rotation of the main firing lever 4, and the adjustment gear of the transmission gear portion 15 of the second gear body 72 and the volume gear body 19. The engagement with the portion 52 causes the volume gear body 19 to rotate in the direction of increasing the firing force in conjunction with the rotation of the second gear body 72, and the firing force of the game ball is increased by the volume 1. Further, if only the secondary firing lever 9 is rotated from the origin position in the direction of increasing the firing force (pressing operation) without being rotated while the main firing lever 4 is maintained at the origin position, the secondary firing lever 9 is The first gear body rotates in association with the rotation of the secondary firing lever 9 by rotating around the rotation axis 82 and meshing with the secondary firing gear portion 8 of the secondary firing lever 9 and the operation gear portion 11 of the first gear body 71. 71 and the second gear body 72 rotate in the direction in which the firing force increases, and interlock with the rotation of the second gear body 72 by meshing between the transmission gear portion 15 of the second gear body 72 and the adjustment gear portion 52 of the volume gear body 19. Then, the volume gear body 19 rotates in the direction of increasing the firing force, and the firing force of the game ball is increased by the volume 1.

  The inclined guide surface 77 has an arc shape centered on the main rotation axis 81 and extends from the engagement recess 76 in the firing force increasing direction so as to be inclined toward the front (on the transmission guide 73 side). A portion of the inclined guide surface 77 adjacent to the engagement recess 76 is steeply inclined from the engagement recess 76 between the flat portion 77a that hardly tilts forward and backward, and between the flat portion 77a and the engagement recess 76. And a rising portion 77b for relaxing a step with the engaging recess 76.

  When rotational force in the firing force increasing direction is applied to the first gear body 71 in a state where the rotation of the second gear body 72 from the basic relative rotational position in the firing force increasing direction is restricted, the inclined guide surface 77 rises. The locking projection 75 is guided forward by the shape of the front end portion of the portion 77b and the locking projection 75, the transmission guide 73 moves forward against the biasing force of the coil spring 74, and the locking projection 75 is engaged with the engagement recess. Riding on the inclined guide surface 77 from 76, the engagement of the locking projection 75 and the engagement recess 76 is released, and relative rotation of the first gear body 71 in the direction of increasing the firing force with respect to the second gear body 72 is allowed. The first gear body 71 idles (see FIG. 11). The flat portion 77a stabilizes the behavior of the locking protrusion 75 that has climbed over the rising portion 77b.

  When the first gear body 71 is rotated relative to the second gear body 72 from the basic relative rotation position in the firing force increasing direction and the first gear body 71 is applied with a rotational force in the firing force decreasing direction, the inclination is inclined. The locking projection 75 on the guide surface 77 slides toward the engagement recess 76 due to the biasing force of the coil spring 74 and the inclination of the inclined guide surface 77, and the first gear body 71 moves relative to the second gear body 72. Both gear bodies 71 and 72 return to the basic relative rotation position by relative rotation in the direction of reduced firing force.

  As described above, the relative rotation control mechanism 90 is engaged with both the gear bodies 71 and 72 in a state where the first gear body 71 and the second gear body 72 are set to the basic relative rotation position. , 72 is restricted, and the rotational force in the firing force increasing direction is applied to the first gear body 71 in a state where the rotation of the second gear body 72 from the basic relative rotational position in the firing force increasing direction is restricted. Then, the engagement with the second gear body 72 is released to allow relative rotation of the first gear body 71 with respect to the second gear body 72 in the firing force increasing direction, and the first gear body 71 is in the second state. When a rotational force in the direction of decreasing the firing force is applied to the first gear body 71 in a state of relative rotation from the basic relative rotational position to the firing force increasing direction with respect to the gear body 72, the first gear with respect to the second gear body 72 is applied. Allowing relative rotation of the body 71 in the direction of decreasing the firing force, To return to the rotation position.

In addition, when only the main firing lever 4 rotates to the maximum in the firing force increasing direction while the secondary firing lever 9 is maintained at the origin position, only the secondary firing lever 9 is launched while the primary firing lever 4 is maintained at the origin position. The gear-side stopper 92 contacts the base-side upper limit stopper 91 both in the case of the maximum rotation in the direction of increasing the force and in the case where both the main firing lever 4 and the auxiliary firing lever 9 are rotated in the maximum in the direction of increasing the firing force. In contact therewith, the rotary shaft member 18 of the volume 1 rotates to a predetermined maximum firing force position (for example, 125 ° from the origin position) and does not rotate any further.
[Playing a game ball]
In the initial state in which the game ball is stopped, the main firing lever 4, the secondary firing lever 9, the first gear body 71, the second gear body 72, and the volume gear body 19 are origins that are rotation limits in the firing force decreasing direction. The first gear body 71 and the second gear body 72 are set to the basic relative rotation position.

  The player who starts the game does not operate the secondary firing lever 9 and rotates the main firing lever 4 from the origin position in the firing force increasing direction. When the main firing lever 4 rotates, the secondary firing lever 9 revolves around the main rotation axis 81 without rotating. Since the secondary firing gear portion 8 of the secondary firing lever 9 and the operation gear portion 11 of the first gear body 71 mesh with each other, the first gear body 71 moves in the direction of increasing firing force in conjunction with the rotation of the primary firing lever 4. Rotate. The first gear body 71 and the second gear body 72 are set at the basic relative rotational position, and the locking projection 75 of the transmission guide 73 is engaged with the engagement recess 76 of the second gear body 72 by the biasing force of the coil spring 74. Therefore, when the relative rotation between the two gear bodies 71 and 72 is restricted and the first gear body 71 rotates, the second gear body 72 rotates integrally with the first gear body 71. Since the transmission gear portion 15 of the second gear body 72 and the adjustment gear portion 52 of the volume gear body 19 are engaged with each other, the volume gear body 19 rotates in the direction of increasing the firing force in conjunction with the rotation of the second gear body 72. However, the firing force of the game ball is changed (increased) by the volume 1. That is, the player can fire the game ball with a desired launch force by appropriately adjusting the amount of rotation of the main launch lever 4 from the origin position.

  For example, when it becomes necessary to increase the launching power of a game ball in the middle of a game, such as a transition to a game (right-handed game) that requires the launch of a game ball to the right area of the game area, While the rotation position of the main firing lever 4 is maintained, the sub operation part 34 of the sub firing lever 9 is pressed to rotate the sub firing lever 9 in the firing force increasing direction. Since the secondary firing gear portion 8 of the secondary firing lever 9 and the operation gear portion 11 of the first gear body 71 mesh with each other, the first gear body 71 launches in conjunction with the rotation (spinning) of the secondary firing lever 9. Rotate in an increasing direction. Since the first gear body 71 and the second gear body 72 are set at the basic relative rotation position, the relative rotation between the both gear bodies 71 and 72 is restricted, and when the first gear body 71 rotates, the second gear The body 72 rotates integrally with the first gear body 71, the volume gear body 19 rotates in the direction of increasing the firing force in conjunction with the rotation of the second gear body 72, and the firing force of the game ball is changed by the volume 1 ( Increased). That is, the player can increase the firing force of the game ball by depressing the secondary firing lever 9 while maintaining the main firing lever 4 at a desired rotational position. Further, when the increase in the firing force (right-handed game) is ended and the original firing force is restored, the player releases the pressing operation of the secondary firing lever 9. When the secondary firing lever 9 is released, the secondary firing lever 9 rotates (rotates) in the direction of decreasing the firing force, and the first gear body 71 and the second gear body 72 rotate together, and the second gear body 72 In conjunction with the rotation, the volume gear body 19 rotates in the direction of decreasing the firing force, and the firing force of the game ball is changed (decreased) by the volume 1.

  The rotation limit of the second gear body 72 in the direction of increasing the firing force is restricted to the maximum firing force position when the gear-side stopper 92 contacts the base-side upper limit stopper 91. That is, the second gear body 72 does not rotate in the direction of increasing the firing force beyond the maximum firing force position, and an excessive load is not applied to the volume 1.

  In a state in which the second gear body 72 has reached the maximum firing force position, at least one of the main firing lever 4 or the secondary firing lever 9 has not reached the rotation limit in the firing force increasing direction, and the player When the secondary firing lever 9 is operated in the firing force increasing direction and a rotational force in the firing force increasing direction is applied to the first gear body 11, the locking projection 75 of the transmission guide 73 resists the biasing force of the coil spring 74. Then, it climbs onto the inclined guide surface 77 from the engaging recess 76 of the second gear body 72, the engagement between the locking projection 75 and the engaging recess 76 is released, and the first gear body 71 is fired to the second gear body 72. Relative rotation in the direction of increasing force is allowed. Therefore, an excessive load in the firing force increasing direction input to the first gear body 71 and the second gear body 72 can be mitigated by the relative rotation of the first gear body 71 and the second gear body 72.

  When returning the first gear body 71 that has rotated relative to the second gear body 72 from the basic relative rotational position in the direction of increasing firing force to the basic relative rotational position, the player fires the main firing lever 4 or the secondary firing lever 9. By operating in the direction of decreasing force, a rotational force in the direction of decreasing firing force is applied to the first gear body 71. When the rotational force in the firing force decreasing direction is applied to the first gear body 71, the locking protrusion 75 on the inclined guide surface 77 is engaged with the engaging recess 76 by the urging force of the coil spring 74 and the inclination of the inclined guide surface 77. Slid to move toward the engagement recess 76, and both gear bodies 71 and 72 return to the basic relative rotation position.

As described above, according to the present embodiment, the firing force is increased or decreased by the pressing operation of the sub-launching lever 9 on the basis of the state in which the game ball is being fired at the desired firing force by the rotation operation of the main firing lever 4. Can do. When excessive rotational force is input to the first gear body 71, the rotational limit of the second gear body 72 is restricted by the gear side stopper 92 and the base side upper limit stopper 91, and the second gear body 72 is Since the relative rotation of the first gear body 71 is allowed by the control mechanism 90, it is possible to prevent parts from being broken or broken.
[Modification]
In addition to the base-side upper limit stopper 91, a base-side lower limit stopper 93 (shown by a two-dot chain line in FIGS. 5 and 6) projects forward from the base plate portion 20 of the base body 2. When the gear-side stopper 92 abuts on the base-side lower limit stopper 93, the rotation limit of the second gear body 72 in the direction of decreasing the firing force is restricted to the origin position. That is, the base-side lower limit stopper 93 and the gear-side stopper 92 function as minimum firing force setting means for restricting the rotation limit of the second gear body 72 in the firing force decreasing direction to the origin position.

  Thus, since the base side lower limit stopper 93 that restricts the rotation limit of the second gear body 72 in the direction of decreasing the firing force to the origin position is provided, the firing force from the basic relative rotational position with respect to the second gear body 72 is provided. When returning the first gear body 71 that has rotated relative to the increase direction to the basic relative rotation position, both the gear bodies 71 and 72 are simply operated by the player operating the main firing lever 4 or the secondary firing lever 9 in the firing force decreasing direction. Even if it does not return to the basic relative rotation position, the first gear body 71 is applied by applying a rotational force in the direction of decreasing the firing force to the first gear body 71 after returning the second gear body 72 to the origin position. Rotates relative to the second gear body 72 in the direction of decreasing the firing force. Therefore, both the gear bodies 71 and 71 can be reliably returned to the basic relative rotation position.

  When the base side lower limit stopper 93 is provided, a flat guide surface that hardly tilts forward and backward may be provided instead of the inclined guide surface 77.
