TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gaming machine such as a pachinko gaming machine having a detachable launch operation unit for operating the launch of a game ball.
[0002]
[Prior art]
In a conventional gaming machine, for example, a pachinko gaming machine, when a player turns a firing operation handle of a firing operation unit, a firing switch is turned on, and a firing device operates based on a signal from the firing switch to operate a game. Can fire a ball.
The firing operation handle is normally biased so that the firing switch is turned off, and in order to continuously fire game balls, the firing operation handle is rotated against the urging force of the return spring. We need to continue.
[0003]
However, some players try to forcibly push a foreign object such as a coin or a toothpick into a gap between the rotating portion and the fixed portion of the firing operation handle in order to fix the firing operation handle and continuously launch the game ball. Some people go out. When the foreign object is pushed in this way, there is a possibility that the rotation axis of the firing operation unit is distorted or the casing of the firing operation handle is damaged. Therefore, some conventional pachinko gaming machines have a configuration in which the firing operation unit is assembled separately from the front frame so that the firing operation unit can be replaced later (for example, see Patent Documents 1 and 2). ).

I have. In addition, the launching device 23 has a launch rail 64 at the left end of the front surface of the mounting member 55 such that the tip of the launching punch 62 is located above the inclined lower end of the launch rail 64. A ball feeder 65 is provided above the incline so that game balls guided from the upper plate 14 can be sent out to a ball launcher 66 formed at the lower end of the launch rail 64. As shown in FIG. 8D, the firing rail 64 has a groove having a substantially V-shaped cross section formed on the inclined upper surface along the longitudinal direction.
[0019]
The transmission member 56 is disposed so as to be located just behind the mounting position of the firing operation unit 21 in the mounting member 55, and is provided on the front surface at the other end (rear end) of the connecting member 24. A plurality of connecting member engaging holes 69 for engaging the pawls 68 (see FIG. 5) are provided, and a transmission member rotating shaft 70 extends rearward from the center on the back surface and is rotatable with respect to the mounting member 55. Penetrated in the state. In addition, the transmitting member 56 slightly protrudes an arc-shaped spacer 71 from around the center of the rear surface to prevent the rear surface of the transmitting member 56 from coming into surface contact with the front surface of the mounting member 55 and to smoothly rotate. The movement allows the player to adjust the firing force without stress (see FIG. 6).
[0020]
The transmission gear 57 is disposed on the back side of the attachment member 55 and behind the transmission member 56, that is, behind the attachment position of the firing operation unit 21, and is fixed at the center to the tip of the transmission member rotation shaft 70. Thus, it is configured to be able to rotate together with the transmission member 56. In addition, the transmission gear 57 also slightly raises the boss 73 from the periphery of the center toward the mounting member 55, and forms a gap to prevent friction between the transmission gear 57 and the rear surface of the mounting member 55. . The recessed chamber 34 (bottom 34a) of the mounting base 18, the transmission member 56, the mounting member 55, and the transmission gear 57 are moved back and forth with respect to the screw hole 48 of the support 36 and the communication hole 34b of the bottom 34a. They are arranged in a state of being superposed in the directions.
[0021]
The spring 61 for generating a resilient force on the game ball is a right-handed torsion coil spring that divides a horizontal cylindrical casing 60 provided on the back side of the mounting member 55 into front and rear parts and is housed in the casing 60. One end is locked to the first casing member 75 located on the mounting member 55 side, and the other end is locked to the second casing member 76 facing the first casing member 75, respectively.
[0022]
The first casing member 75 is mounted in a freely rotatable state, that is, in a free state, on a punch rotating shaft 78 supported by the mounting member 55 and having the firing punch 62 attached to the front end, that is, the outer peripheral surface. A casing rotation gear 79 is formed in an arc shape, and the transmission gear 57 is connected to the casing rotation gear 79 via a connection gear 58. With such a configuration, the first casing member 75 can rotate with the rotation of the transmission gear 57, that is, the transmission member 56 and the firing force adjustment handle 38. Therefore, the first casing member 75 can move the engagement position with the spring 61, that is, the end of the spring 61 along the circumference.
[0023]
In the present embodiment, in a normal state where the firing force adjustment handle 38 is not operated, the spring 61 is not receiving a load, and when the firing force adjustment handle 38 is rotated, transmission is performed in accordance with the amount of rotation operation. The member 56, the transmission gear 57, the connecting gear 58, and the casing rotating gear 79 rotate, respectively, so that the first casing member 75 narrows the winding of the spring 61 (counterclockwise in FIG. 8B). Rotate. Therefore, the spring 61 can change the elastic force for restoring according to the degree of being narrowed down by the first casing member 75. In addition, the casing rotation gear 79 has a rotation restricting stopper 80 at an end to limit the amount of rotation of the first casing member 75, and the firing force of the game ball becomes too strong due to the excessive elastic force of the spring 61. Has been blocked.
[0024]
On the other hand, the second casing member 76 is configured such that the rear end portion of the punch rotating shaft 78 is fixed inside, and can be rotated together with the firing punch 62 with respect to the mounting member 55. Further, the second casing member 76 has a cam follower 82 extending from the outer peripheral surface, and the tip of the cam follower 82 is in contact with a cam 84 rotated by a firing motor (electric rotary drive source) 83. Note that the cam 84 has a substantially curved spherical shape with a step surface facing the rotation direction formed in the middle of the cam surface, and has a hook portion 85 such that the tip of the cam follower 82 is hooked. When rotated counterclockwise (see FIG. 8B) when viewed from behind while the cam follower 82 is hooked, the second casing member 76 can be rotated clockwise together with the cam follower 82. With such a configuration, the second casing member 76 can increase the urging force (elastic force) of the spring 61 while rotating the firing punch 62. A firing switch (not shown) for turning on / off the firing motor 83 is incorporated inside the firing force adjustment handle 38, and detects that the firing force adjustment handle 38 has been turned by the player. The firing motor 83 is turned on, and the firing motor 83 is turned off in a normal state where the rotation operation is not performed.
[0025]
The launching punch 62 extends downward from the front end of the punch rotating shaft 78 on the front side of the mounting member 55, and has a resilient portion 87 made of a coil spring or the like attached to the tip. When the cam follower 82 comes off the hooking portion 85, the second casing member 76 and the punch rotating shaft 78 return and rotate by the urging force of the spring 61, and the elastic portion 87 moves to the ball emitting portion 66 of the firing rail 64. The game ball is configured to be launched by vigorously rushing. The firing punch 62 has an end on the punch rotating shaft 78 side in contact with a cushion rubber 88 arranged on the opposite side of the ball rotating portion 66 with the punch rotating shaft 78 interposed therebetween. The rotation range is regulated so that the launching portion 87 does not move on the launching rail 64 ahead of the ball launching portion 66. Further, the launching punch 62 is configured such that an arm 90 made of a wire is extended toward the ball feeder 65 on the way, and the feed lever 91 of the ball feeder 65 is pushed down by the arm 90 while the launching punch 62 retreats. Have been. Thereby, the game balls guided from the upper plate 14 into the ball feeding device 65 are supplied one by one onto the firing rail 64.
[0026]
The above-described launching device 23 includes a transmitting member 56 having a transmitting member opening 94 (corresponding to a transmitting member escape portion of the present invention), an attaching member 55 having an attaching member opening 95, and a transmitting gear 57 having a transmitting gear opening. In the normal state in which the firing force adjustment handle 38 is not operated for adjustment, that is, in a state in which the gears 56 and 57 are not rotated, a plurality of the gears 96 are opened (in this embodiment, three with a phase shift of 120 degrees). The openings 94, 95, and 96 are arranged one by one behind the screwing member 52, and are arranged along the mounting / removing direction of the screwing member 52. The transmission member opening 94 is formed by providing a notch on the outer periphery of the transmission member 56, and the attachment member opening 95 and the transmission gear opening 96 open through holes in the attachment member 55 and the transmission gear 57. It is formed. Further, since the openings 94, 95, and 96 are formed at positions equidistant from the center of the transmission member rotating shaft 70, even when the firing force adjustment handle 38 is adjusted, the respective openings 94, 95, and 96 are adjusted. The openings 94, 95, and 96 can be arranged in the mounting / removing direction of the screw member 52 every time the openings 94, 95, and 96 rotate by the arrangement phase.
[0027]
Each of the openings 94, 95, and 96 is formed with a screw member 52 or a tool (for example, a driver) T, more specifically, an engaging portion (for example, a driver tip) of the tool T that engages with the screw member 52. ) Are sufficiently open to pass through. Further, a base member opening 100 having the same degree of opening as each of the openings 94, 95, 96 is provided in the launcher mounting portion 99 for mounting the firing device 23 of the front frame base member 4. It is opened to the rear of the screwing position (see FIG. 6B). Therefore, the pachinko gaming machine 1 to which the launching device 23 is attached forms a screwing member attaching operation space 101 from the back surface of the insertion concave chamber 34 which is the launching operation unit attaching portion to the front surface of the attaching member 55, By providing the openings 94, 95, 96 and the base member opening 100 communicating with the joint member mounting operation space 101, a space through which the screw member 52 can pass in the mounting and dismounting direction of the screw member 52 of the firing operation unit 21. The screwing member 52 can be removed or attached even from the back side of the firing device 23. Accordingly, the operation of replacing the firing operation unit 21 can be efficiently performed without removing the firing device 23 and the mounting base 18 from the front frame 3.
[0028]
Then, as described above, the firing device 23 closes the transmission member opening 94, the attachment member opening 95, and the transmission gear opening 96 in a normal state in which the firing force adjustment handle 38 of the firing operation unit 21 is not operated. The openings 94, 95, and 96 are attached and detached without any special adjustment when the firing operation unit 21 is replaced because the screwing members 52 are arranged along the attachment / detachment direction of the screwing member 52. It can be adjusted to the position along the direction. Therefore, the replacement operation of the firing operation unit 21 can be promptly performed, and the operation efficiency can be improved.
[0029]
As shown in FIG. 6, the front frame base member 4 has a hollow shelf 102 (a projecting device guide mounting shelf of the present invention) opened rearward below the space between the projecting operation unit 21 and the projecting device 23. A screw member recovery port 103 through which the screw member 52 can pass is opened in the upper plate of the shelf 102, and an inclined surface 104 inclined backward is formed in the lower plate of the shelf 102. ing. When such a shelf 102 is formed on the front frame base member 4, it functions as a guide for guiding the firing device 23 to the mounting position (the firing device mounting portion 99) at the time of mounting, and fires when mounted. The device 23 can be mounted. Further, when the screwing member 52 is removed during the replacement operation of the firing operation unit 21, an area corresponding to a region below the screwing member mounting operation space 101 between the back surface of the mounting base 18 and the front surface of the mounting member 55. When the screwing member 52 falls, the screwing member 52 passes through the screwing member recovery port 103 and rolls down the inclined surface 104, so that the screwing member 52 can be easily collected from the lower rear of the front frame base member 4. .
[0030]
As described above, the front frame base member 4 opens the screwing member recovery port 103 through which the screwing member 52 can pass below the space between the firing operation unit 21 and the firing device 23. At the time of replacement of the 21, each opening 94, 95, 96 can be adjusted to a position along the mounting / removing direction of the screw member 52 without special adjustment. Therefore, the replacement operation of the firing operation unit 21 can be promptly performed, and the operation efficiency can be improved.
[0031]
Next, the operation of the firing operation unit 21 and the firing device 23 having the above-described configurations will be described.
First, when the player grips the grip portion 37 of the firing operation unit 21 and touches the touch sensor portion 39, the touch sensor portion 39 detects that the player has touched due to a change in the capacitance, and fires. The detection signal is transmitted to the discharge control device 31. Upon receiving the detection signal, the emission control device 31 confirms that the condition for permitting the driving of the emission motor 83 is satisfied, and waits until the emission switch is turned on. Then, when the player starts rotating the firing force adjustment handle 38 while holding the grip portion 37, the firing switch is turned on, and the firing discharge control device 31 drives the firing motor 83.
[0032]
When the firing motor 83 is driven, the cam 84 starts to rotate while abutting the cam follower 82, and simultaneously the second casing member 76 and the punch rotating shaft 78 rotate, and the firing punch 62 retreats. At this time, the ball feeding device 65 supplies one game ball from the upper plate 14 onto the firing rail 64 by operating the arm 90 of the firing punch 62. When the cam follower 82 comes off the hook portion 85 of the cam 84, the elastic force of the spring 61 causes the second casing member 76, the punch rotating shaft 78, and the firing punch 62 to return rapidly and rotate (advance), thereby causing the elasticity. The firing unit 87 fires the game ball on the firing rail 64 to the game area 10. If the firing switch is in the ON state, the cam 84 continues to rotate, and the hook 84 is again hooked on the cam follower 82 to prepare for the next game ball firing.
[0033]
Further, when the rotation amount (adjustment operation amount) of the firing force adjustment handle 38 is adjusted, the first casing member 75 is rotated via the firing force transmission shaft portion 42, the transmission member 56, the transmission gear 57, and the connection gear 58. By adjusting the degree of narrowing of the spring 61, that is, the elastic force of the spring 61, the launching rotation speed of the firing punch 62 is changed and the flying distance of the game ball can be adjusted. Therefore, if the amount of rotation of the firing force adjustment handle 38 is increased, the resilience of the spring 61 can be increased and the flight distance of the hit ball can be increased, while the amount of rotation of the firing force adjustment handle 38 can be reduced. If this is the case, the resilience of the spring 61 can be made close to the normal state, and the flight distance of the hit ball can be shortened.
[0034]
By the way, as shown in FIG. 10, if the transmission member 56 is disposed so that the transmission member opening 94 is located in the middle of the adjacent connection member engagement hole 69, the connection member engagement hole 69 and the transmission member opening It is easy to avoid that the thickness between the first and fourth portions 94 becomes extremely thin. Therefore, the connecting member engaging hole 69 is less likely to be distorted, and the adjustment operation amount can be easily transmitted to the transmission gear 57 accurately even when the firing force adjustment handle 38 is repeatedly operated, which is preferable.
[0035]
In the transmission member 56 shown in FIG. 10, the transmission member opening 94 and the connection member engagement hole 69 are alternately arranged along the circumferential direction of the transmission member 56. The amount of adjustment operation from the firing force adjustment handle 38 can be transmitted to the transmission member 56 while dispersing the transmission force without concentrating the transmission member 56 at one location. Further, even if the connection member engaging hole 69 is opened close to the center of the rotation shaft, the rotation torque can be reduced to suppress the deformation of the transmission member 56, and the deviation of the adjustment operation amount due to the transmission can be reduced. Thus, the size of the component can be reduced, and the manufacturing cost can be reduced.
[0036]
Although the transmitting member opening 94 in the present embodiment is formed by a cutout provided on the outer periphery of the transmitting member 56, the transmitting member opening 94 communicates from the front side to the rear side of the firing device 23 to allow the screwing member 52 to pass therethrough. Any structure may be used as long as it is formed. For example, the outer diameter of the transmission member 56 may be increased, and the transmission member opening 94 may be formed by a through hole, or such that the outer peripheral portion of the transmission member 56 does not interfere with the detachable screw member 52. The outer diameter of the transmission member 56 may be reduced to secure a space through which the screw member 52 can pass.
[0037]
As shown in FIG. 11, the transmission gear 57 may have an opening peripheral wall 107 extending from the peripheral edge of the transmission gear opening 96 along the attaching / detaching direction of the screw member 52. The opening peripheral wall 107 extends rearward from the opening peripheral edge of the transmission gear opening 96 to just before the launcher mounting portion 99 of the front frame base member 4. When such an opening peripheral wall 107 is provided, the periphery of the transmission gear opening 96 of the transmission gear 57 is reinforced, and damage to the transmission gear 57 can be prevented. Therefore, the life of the transmission gear 57 is unlikely to be shortened, and the labor and cost for maintenance can be reduced. When a tool such as a screwdriver is used for attaching and detaching the screwing member 52, the opening peripheral wall 107 serves as a guide (guide portion) for guiding the tool to the mounting position of the firing operation unit 21. The attachment / detachment can be quickly carried out, and the work of replacing the firing operation unit 21 can be efficiently advanced. The opening peripheral wall 107 may extend in the attachment / detachment direction of the screw member 52, and may extend forward, for example.
[0038]
By the way, the mounting base 18 of the above-described embodiment fixes the protruding position of the grip portion 37 from the front frame 3 when the firing operation unit 21 is mounted. However, the present invention is not limited to this. It may be a mounting base that can adjust the front and rear positions of the mounting base. For example, the mounting base 18 ′ of the second embodiment shown in FIG. 12 is basically the same as the mounting base 18 of the above-described embodiment, but the depth of the insertion concave chamber 34 for locking the firing operation unit 21. The difference is that the side bottom portion 34a is provided with a position adjustment mechanism 110 that can adjust the locking position of the support portion 36 in the front-rear direction. The position adjusting mechanism 110 is configured such that a female screw hole 112 is opened in a projection 111 provided on the back side of the rear bottom portion 34a of the insertion concave chamber 34, and a stopper 113 having a male screw shaft is screwed into the female screw hole 112. A stopper 113 is provided at the tip of the stopper 113 for contacting the end surface of the support 36. Behind the position adjusting mechanism 110, the transmission member opening 94, the mounting member opening 95, the transmission gear opening 96 of the firing device 23, and the base member opening 100 of the front frame base member 4 are provided with the stopper 113. They are arranged along the moving direction.
[0039]
To adjust the front-rear position of the firing operation unit 21 by providing the position adjusting mechanism 110 as described above, first, the locked state is released by loosening the screwing member 52 that locks the support portion 36 or the like. Then, the firing operation unit 21 is made to be able to move back and forth. Then, a tool such as a driver is inserted into each of the openings 94, 95, and 96 from behind the firing device 23, and the tip of the contact portion 114 is moved to a desired position by turning the stopper 113. When the contact portion 114 is moved, the support portion 36 is moved in the front-rear direction to abut the end face against the contact portion 114, and the support portion 36 is again locked in the insertion concave chamber 34 by the screwing member 52.
[0040]
As described above, when the position adjusting mechanism 110 is provided on the mounting base 18 ', the position of the grip portion 37 can be adjusted to the player's preference. Therefore, the gaming shop in which such a pachinko gaming machine 1 is installed prepares the pachinko gaming machine 1 such that the position of the grip portion 37 is adjusted to make it different from other shops, so that the player can play the game more comfortably. It can be performed. Further, for the position adjustment of the firing operation unit 21, the adjusting operation can be performed without removing the firing device 23 and the like, and the working efficiency can be improved.
[0041]
If a rotation prevention rod (not shown) made of a bar is inserted into each of the openings 94, 95, and 96, each of the openings 94, 95, and 96 functions as a firing operation lock mechanism. This is preferable because it is possible to prevent an accident in which the firing device 23 is accidentally operated and an operator is hit with a finger or the like by the firing punch 62 at times.
[0042]
In the above-described embodiment, the pachinko gaming machine, which is a typical gaming machine, has been described as an example. However, the present invention is not limited to this. By operating a launch operation unit, a game ball is driven from a launch device into a gaming area. Any game machine may be used as long as it is a game machine that performs a game. For example, a gaming machine such as an enclosed ball-type pachinko machine, an arranged ball-type gaming machine, and a sparrow-ball-type gaming machine for circulating gaming balls enclosed therein may be used.
[0043]
It should be noted that the above-described embodiment is illustrative in all aspects and not restrictive. The present invention is shown not only by the above description but also by the claims, and includes all modifications within the meaning and scope equivalent to the claims.
[0044]
【The invention's effect】
As described above, the present invention has the following effects.
That is, the firing operation unit mounting member is provided with a firing operation unit mounting portion by forming an insertion concave chamber into which the firing operation unit can be inserted, and the firing operation unit is inserted into the insertion concave chamber and the firing operation unit is mounted on the firing operation unit mounting member. In order to mount, a communication hole communicating with the screwing hole of the firing operation unit is formed on the bottom of the insertion concave chamber, and the firing operation unit mounting portion, the transmission member, the mounting member, and the transmission gear are connected with the screwing hole and the communication gear. The transmission member is disposed in a state of being overlapped in the front-rear direction with respect to the hole, the transmission member escape portion in the transmission member, the mounting member opening in the mounting member, and the transmission gear opening in the transmission gear, along the mounting / removing direction of the screwing member. Since each is formed so that it can be arranged, the screwing member can be attached and detached through the transmission member escape portion, the mounting member opening, and the transmission gear opening. Therefore, the launcher unit can be attached to or detached from the attachment base of the front frame without removing the attachment base or the launching device from the front frame, and the burden of replacing the launch operation unit can be reduced.
