Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball game machine including a game board in which a game area is formed and a game ball launching apparatus that launches a game ball into the game area, and more particularly, from the game ball launching apparatus to the game board. It is related with the technique which equalizes the ball jump of the game ball launched.
[0002]
[Prior art]
As a ball game machine equipped with the game ball launching device as described above, a pachinko machine, an arrangement ball machine, a sparrow ball game machine, and the like are generally widely known. In pachinko machines, which are representative of this type of ball game machine, a storage frame for storing a game board is provided above the front frame, which is an open / close mounting frame, and a game board with a game area formed on the front is standing upright. Is held and held by. A lower area of the front frame located below the housing frame is provided with a launching mechanism for launching a game ball and a game ball launching device having a launch rail for guiding the launched game ball toward the upper game board. . The game board is provided with a semi-arc-shaped guide rail that receives the game ball launched from the game ball launching device and guides it to the game area, and the game ball launched from the game ball launching device follows the guide rail. A game is played by being guided to the upper part of the game area and falling in the game area while being played by the game nails.
[0003]
The game ball launching device launches the game ball with a launch intensity corresponding to the operation amount (rotation angle position) of the launch handle for performing the launch operation so that the player can launch the game ball at a desired position in the game area. It is configured. Here, if the operation amount of the launching handle is constant, it is considered that the hitting force by the hammer of the launching mechanism is constant, and the reaching position of the game ball is also constant. However, in reality, a number of components constituting the game ball launching device, for example, a potentiometer built in the launching handle, a rotary solenoid that is a driving source of the hammer, a spring constant of a coil spring fixed to the tip of the hammer, The hit position of the game ball, the inclination angle of the launch rail, and the like are intertwined, and there are individual differences in the arrival position (ball jump) of the shot game ball even if the operation amount is the same.
[0004]
Against this background, in recent years, it seems that the change in the position where the game ball launched from the game ball launching device abuts on the guide rail (referred to as the “sitting point”) has an impact on the ball flight. It has become. Therefore, as a means to adjust the seating point, the firing rail is elastically deformed by displacing the end side of the firing rail up and down, and the rail surface profile (the cross-sectional shape of the rail surface in the direction in which the firing rail extends) is changed. Has proposed an adjustment mechanism for adjusting the firing angle (see Patent Document 1).

[0006]
[Problems to be solved by the invention]
However, in the technique described in the above-mentioned Patent Document 1, since the launch rail itself is elastically deformed, when the end side of the launch rail is displaced, the influence also reaches the base end side, and the ball skip stabilization is achieved. There is a possibility that a change occurs in the hit position of the game ball, which is one of the important elements, that is, the contact position between the hammer and the game ball. In addition, since the firing angle is adjusted by elastically deforming the firing rail, a reaction force corresponding to the amount of deformation is generated during the adjustment. For this reason, when the deformation amount (adjustment amount) increases, the reaction force also increases in proportion to this, and there is a problem that it is difficult to perform fine angle adjustment while resisting this reaction force.
[0007]
Furthermore, after the angle is set, the reaction force is stored in the firing rail, and this reaction force always acts on the screw fixing part for fixing the firing rail in addition to the adjustment screw fixing part for setting the angle. . On the other hand, repetitive stresses such as vibration caused by a launch operation and impact caused by a collision of a foul ball falling from the game board side act on the launch rail during the game. For this reason, it is pointed out that there is a risk that the screw holding and holding force will decrease during long-term game provision, and the launch rail may return to the straight state before adjustment or change to a shape different from that at the time of adjustment. It was.
[0008]
The present invention has been made in view of such problems, and a bullet ball that can easily adjust and uniformize the variation in ball flight that cannot be suppressed only by improving the accuracy of each component constituting the game ball launching device. It is an object of the present invention to provide a launch angle adjustment mechanism for a gaming machine.

[0028]
In the upper part of the guide member 110, the auxiliary rail portion 113 extends obliquely left and right, and the side rail 114 protrudes upward behind the auxiliary rail portion 113. The auxiliary rail portion 113 extends to the left and right so as to communicate with the firing rail 23, and the inclination angle of the rail surface is, as shown in FIGS. 2 and 7A, a central tilt angle position based on the guide member 110. In the state set to, it is formed so as to coincide with the inclination angle of the firing rail 23. In the present specification, for the tilt angle position of the guide member 110, the launch ball B_HThe direction in which the rail surface faces upward as viewed in the traveling direction is defined as a positive angular position, and the direction in which the rail surface faces downward is defined as a negative angular position. The introduction side of the auxiliary rail portion 113 is formed in a smooth curved surface, and the launch ball B that passes above the guide member 110 regardless of whether the guide member 110 is set to a positive or negative angular position._HIs designed to be smoothly guided.
[0029]
The side rail 114 disposed behind the auxiliary rail portion 113 is formed with a protruding piece 114a that protrudes to the right of the main body 111, and this protruding piece 114a is positioned in front of the lower edge of the decorative plate 31. It is arranged as follows. The standing height of the side rail 114 is set to be somewhat larger than the radius of the game ball. On the other hand, even when the guide member 110 is swung in the forward direction, the tip of the protruding piece 114a does not interfere with the firing rail 23. As described above, the tip side is formed in a thin triangular shape. An inclined surface 114b that smoothly guides the projecting ball passing through the front of the side rail is formed at the left end of the protruding piece 114a and the side rail (see FIG. 5).
[0030]
On the other hand, a guide member support boss 120 that is located on the left side of the firing rail 23 and supports the guide member 110 is formed on the game auxiliary board 10 so as to protrude forward. The protruding height of the guide member support boss 120 is set to be the same as or slightly smaller than the depth of the bearing hole 112 of the guide member. A screw receiving hole for fixing the tilt angle setting frame 131 with a screw is formed on the left side and below the guide member support boss 120.
[0031]
The tilt angle setting frame 131 includes a guard wall 132 that covers the left side of the guide member 110, and a guide support portion 133 that covers the lower portion of the guide member and supports the guide member, and uses the same resin material as the rear base 110A. It is integrally molded by the same molding means. A fixing flange 134 having a screw insertion hole for fixing the tilt setting frame 131 to the game assisting board 10 is overhang molded at the upper left and lower ends of the tilt setting frame 131.
[0032]
A plurality of V-shaped groove-shaped inclination setting grooves 135 that can be engaged with and disengaged from the locking projections 115 of the guide member 110 are formed inside the guide support portion 133 in the inclination angle setting frame 131. In the present embodiment, a total of five tilt angle setting grooves 135 are formed on the left and right sides of the central tilt angle setting groove that engages with the locking projection 115 when the guide member 110 is set to the reference angular position. In this example, the guide member 110 is tilted to engage the locking projection 115 with any of the tilt angle setting grooves, so that the tilt angle of the auxiliary rail portion 113 matches the tilt angle of the firing rail 23. Centering on the reference angle position, it can be set in 5 steps, 2 steps in the positive tilt direction that is upward in the traveling direction of the launch ball and 2 steps in the negative tilt direction that is downward in the traveling direction of the launch ball. It has become. A front wall surface having a predetermined height is formed in front of the inclination setting groove 115, and an inclination scale 137 indicating a guide for the inclination angle position of the guide member 110 is formed therein. Each figure shows an example in which graduation lines in the positive direction and the negative direction are formed at equal intervals on the left and right sides with the reference angle position described above as the center.
[0033]
The above-described constituent members are assembled to the game auxiliary board 10 to form the tilt angle adjusting mechanism 100. The guide member 110 is assembled by fitting and supporting the bearing hole 112 to the guide member support boss 120 and screwing and fastening a support screw 128 from the front through a washer. When the guide member 110 is assembled to the guide member support boss 20, the guide member 110 is supported so as to be able to tilt around the axis of the guide member support boss and to slide in the direction in which the long hole of the bearing hole 112 extends.
[0034]
Next, the tilt angle setting frame 131 is assembled to the game auxiliary board. When the inclination angle setting frame 131 is assembled, the locking projection 115 of the guide member 110 can be engaged with and disengaged from the inclination angle setting groove 135, and the guide member 110 is slid upward using the operation knob portion 118m, and the appropriate angle position is obtained. By sliding downward, the locking projection 115 can be engaged with the tilt angle setting groove 135 and the guide member can be locked at the tilt angle position. At this time, from the position of the index 117 of the front tip with respect to the inclination scale 137 of the guide support portion, the inclination direction and the degree of the guide member 110 can be confirmed.
[0035]
Then, with the locking projection 115 engaged with the tilt angle setting groove 135, the locking screw 138 screwed into the center of the operation knob portion 118m is tightened. Then, the locking screw 138 moves toward the game assisting board 10 in response to the screwing, and the tip portion at the tip engages with the game assisting board 10, while the reaction force causes the main body 111b of the center plate 110B to move. The front tip 110C engages with the back surface of the guide support portion 133, and the guide member 110 is firmly fixed at the angular position.
[0036]
Therefore, by loosening the locking screw 138 and moving the guide member 110 upward, tilting, and downward, the tilt angle position of the guide member 110, that is, the tilt angle of the auxiliary rail portion 113 is changed from the support screw 128 to the locking screw 138. Can be adjusted and set in multiple stages at a predetermined angle pitch determined by the relationship between the length of the arm up to and the formation pitch of the tilt angle setting groove 135, and by tightening the locking screw 138 at the set tilt angle position The angular position can be fixed.
[0037]
As described above, in the firing angle adjusting mechanism 100 of the present embodiment, the locking protrusion 115 formed at the lower end of the guide member 110 and the plurality of inclination setting grooves 135 formed inside the guide support portion 133 are mainly used. The tilt angle setting structure 130 is configured, and the locking projections 115 of the guide member supported by the guide member support boss 120 are engaged with and locked to any one of the tilt angle setting grooves 135, so that a plurality of preset angles are set. The guide member 110 can be fixed at any of the tilt angle positions.
[0038]
In front of the guide member 110 and the tilt setting frame 131, a case cover 11 that covers the board surface from the center to the left side of the front surface of the game auxiliary board 10 is attached. The case cover 11 is formed with a flying guide 12 that is located above the extension line of the launch rail 23 and extends obliquely upward to the left, and is opened upward between the guide member 110 and the guide rail 33 behind the case guide 11. A foul ball collection port 13 is formed. A foul ball collection passage 14 connected to the lower ball tray 7 is formed below the foul ball collection port 13, and a foul ball that has fallen along the guide rail 33 without reaching the game area PA is a foul ball collection port. 13, and is collected in the lower ball tray 7 through the foul ball collection passage 14.
[0039]
For this reason, the launch ball B launched from the game ball launcher and flies to the launch passage 34_HIs guided toward the guide rail 33 without directly colliding with the glass plate of the glass door 5. On the other hand, the foul ball that has fallen along the guide rail 33 without reaching the game area PA falls into the foul ball collection port 13 without falling to the front side of the game auxiliary board 10 and enters the lower ball tray 7. Collected. At this time, the foul ball dropped into the foul ball collection port 13 is received by the guard wall 132 and guided to the foul ball collection passage 14 so as not to collide with the guide member 110. A long hole-like tilt angle setting window 17 is formed in the front surface of the case cover 11 so that the tilt angle position of the guide member 110 can be adjusted and the set position can be visually confirmed.
[0040]
In the firing angle adjustment mechanism 100 configured as described above, the locking screw 138 is loosened and the guide member 110 is moved up, tilted, and moved down, so that the tilt angle position of the guide member 110, that is, the auxiliary rail portion 113. Launch ball B by adjusting the tilt angle step by step_HCan be fixed to the adjusted firing angle by tightening the locking screw 138.
[0041]
When adjusting the launch angle of the game ball, the launch of the game ball that is launched by the launch mechanism 21 in the reference angle position setting of the guide member 110 that is the initial setting, that is, the angle setting in which the locking protrusion 115 points vertically downward is set. The strength is set to a reference strength, and the tilt angle position of the guide member 110 is adjusted so that the seating point of the shot game ball on the guide rail 33 is a predetermined position. Here, there are various methods for setting the firing intensity to the reference intensity. For example, the rotation angle position of the firing handle 8 is set to a predetermined rotation angle position, or an operation corresponding to the rotation angle position is performed. A signal is input to the control board of the launching mechanism 21 or a reference power command signal is input to a drive source (rotary solenoid or motor) of the launching mechanism 21 to launch a game ball with a constant hitting force.
[0042]
The game ball hit by the hammer of the launch mechanism 21 and launched leftward rolls along the rail surface so as to be pressed against the launch rail 23 by a relative action (reaction force) with the launch rail 23 extending obliquely upward. The air travels through the auxiliary rail portion 113 and flies over the foul ball collection port 13 toward the launch passage 34.
[0043]
Here, a side rail 114 is provided behind the auxiliary rail portion 113, and a smooth inclined surface 114 b is formed at the left end portion of the side rail 114. For this reason, the launch ball generally moves on the center line of the rail surface due to the V-groove configuration of the launch rail and passes through the auxiliary rail portion 113 without contacting the side rail 114. Even if it is struck by a hammer before it stabilizes and it moves along the path closer to the game board, it is guided by this side rail 114 and flies to the launch passage 34.
[0044]
In addition, since the side rail 114 is disposed in front of the lower edge of the decorative plate 31, even if the cell stretched on the surface of the decorative plate 31 is peeled off, the projecting ball is peeled off or under the decorative plate 31. It will not get caught on the edge corners.

When it is determined that the observed seating point is higher than the range of the reference seating point, the locking screw 138 is loosened to release the fixing of the guide member 110, and the guide member 110 is moved using the operation knob 118m. Tilt in the negative tilt direction, the tilt angle of the auxiliary rail portion 113 is changed to the launch ball B_HThe locking projection 115 is engaged with the inclination angle setting groove on the first stage, and the locking screw 138 is temporarily tightened. Therefore, the seating point is confirmed, and when it is within the range of the reference seating point, the locking screw 138 is tightened at the angular position. As a result, the guide member 110 is fixed to the tilt angle position of the -1st stage, and the tilt angle of the auxiliary rail portion 113 is fixedly held at the angle position adjusted downward.
[0047]
On the other hand, when it is determined that the observed seating point is lower than the range of the reference seating point, the locking screw 138 is loosened to release the fixing of the guide member 110, and the guide member 110 is utilized using the operation knob portion 118m. Is tilted in the positive tilt direction, and the tilt angle of the auxiliary rail portion 113 is changed to the launch ball B_HThe locking protrusion 115 is engaged with the +1 stage inclination angle setting groove, and the locking screw 138 is temporarily tightened. Therefore, the seating point is confirmed, and when it is within the range of the reference seating point, the locking screw 138 is tightened at the angular position. Thereby, the guide member 110 is fixed at the tilt angle position of the +1 stage, and the tilt angle of the auxiliary rail portion 113 is fixedly held at the angle position adjusted downward.
[0048]
Therefore, according to the launch angle adjusting mechanism 100 described above, it is possible to easily adjust the launch angle of the game ball, so that there is an individual difference in the ball jump due to variations in each component of the pachinko machine. However, by adjusting the launch angle of the game ball, the seating point on the guide rail 33 can be adjusted within a certain range, and the ball flight can be made uniform. Further, since the firing angle adjusting mechanism 100 is configured to lock the guide member by the engagement between the locking protrusion and the inclination angle setting groove, the adjusted firing angle can be stably maintained over a long period of time.

[0070]
For this reason, the launch ball B launched from the game ball launcher and flies to the launch passage 34_HIs guided toward the guide rail 33 without directly colliding with the glass plate of the glass door 5. On the other hand, the foul ball that has fallen along the guide rail 33 without reaching the game area PA falls into the foul ball collection port 13 without falling to the front side of the game auxiliary board 10 and enters the lower ball tray 7. Collected. At this time, the foul ball dropped into the foul ball collection port 13 is received by the guard wall 15 and guided to the foul ball collection passage 14 so as not to collide with the main body portion 211 of the guide member and the tilt adjustment lever 231. . A circular tilt setting window 17 is formed on the right side of the guard wall 15 on the front surface of the case cover 11 to adjust and fix the tilt adjusting lever 231 and to visually check the setting position of the tilt adjusting lever 231. It can be done.
[0071]
In the firing angle adjusting mechanism 200 configured as described above, the tilting angle position of the guide member 210, that is, the tilt angle of the auxiliary rail portion 213 is stepped by loosening the locking screw 238 and rotating the tilt angle adjusting lever 231. Adjusted to launch ball B_HCan be fixed to the adjusted firing angle by tightening the locking screw 238.
[0072]
When adjusting the launch angle of the game ball, the launch of the game ball launched by the launch mechanism 21 in the initial setting of the reference angle position of the guide member 210, that is, the angle setting in which the tilt adjustment lever 231 points vertically downward. The strength is set to a reference strength, and the tilt angle position of the guide member 210 is adjusted so that the seating point of the fired game ball on the guide rail 33 becomes a predetermined position. The method for setting the firing intensity to the reference intensity is as described above.
[0073]
The game ball hit by the hammer of the launch mechanism 21 and launched leftward rolls along the rail surface so as to be pressed against the launch rail 23 by a relative action with the launch rail 23 extending obliquely upward. It flies over the foul ball collection port 13 toward the launch passage 34 through the rail portion 213.
[0074]
Here, a side rail 214 is provided in the auxiliary rail portion 213, and the side rail 214 is disposed in front of the lower edge of the decorative plate 31. For this reason, even if the cell stretched on the surface of the decorative board 31 is peeled off, the side rail 214 is pressed against the peeled cell, and the launch ball is caught by the peeled cell, or the peeling of the cell is advanced. There is no. On the other hand, the game ball that the game ball has moved on the forward path away from the game board 30 and the game ball guided forward in contact with the side rail 214 are guided in contact with the flight guide 12 of the case cover, and the glass door It flies toward the guide rail 33 without directly colliding with the glass plate 5.
[0075]
Launch ball B that flew through launch path 34_HIs seated on the guide rail 33 at a height position corresponding to the combination of each component including the game ball launching device 20. Therefore, the observed seating point is compared with the reference seating point range in the pachinko machine PM, and when it is within the reference seating point range, the height / lowness is determined. In addition, each method mentioned above can be used for determination of a seating point.
[0076]
When it is determined that the observed seating point is higher than the range of the reference seating point, the locking screw 238 is loosened to release the fixing of the guide member 210, and the tilt angle adjusting lever 231 is rotated clockwise. The guide member 210 is tilted in the negative tilt direction, and the tilt angle of the auxiliary rail portion 213 is changed to the launch ball B._HTilt in the downward direction as seen in the direction of travel. At this time, the locking protrusion fitted in the central tilt setting hole moves in the negative direction, moves to the first-stage tilt setting hole, fits with a click feeling, and is locked at the angular position. . Therefore, the seating point is confirmed, and when it is within the range of the reference seating point, the locking screw 238 is tightened at the angular position. As a result, the tilt angle adjusting lever 231 and the guide member 210 are fixed at the tilt angle position of the first stage, and the tilt angle of the auxiliary rail portion 213 is fixedly held at the angle position adjusted downward.
[0077]
On the other hand, when it is determined that the observed seating point is lower than the range of the reference seating point, the locking screw 238 is loosened to release the fixing of the guide member 210, and the tilt adjustment lever 231 is rotated counterclockwise. Then, the guide member 210 is tilted in the positive tilt direction, and the tilt angle of the auxiliary rail portion 213 is changed to the launch ball B._HTilt upward as seen in the direction of travel. At this time, the locking projection fitted in the central inclination setting hole moves in the positive direction, moves to the +1 stage inclination setting hole, fits with a click feeling, and is locked at the angular position. Therefore, the seating point is confirmed, and when it is within the range of the reference seating point, the locking screw 238 is tightened at the angular position. As a result, the tilt angle adjusting lever 231 and the guide member 210 are fixed at the tilt angle position of the +1 stage, and the tilt angle of the auxiliary rail portion 213 is fixedly held at the angle position adjusted downward.
[0078]
The adjustment operation of the tilt angle can be performed stepwise with a clear click feeling by swinging the operation lever portion 233 left and right, and can be reliably fixed at the angle position after the adjustment setting. In the adjustment operation, the direction of the operation lever portion 233 serves as an index for clearly indicating the inclination direction and the stage of the auxiliary rail portion 213, and the inclination setting position is selected according to the height and level of the observed seating point. In addition, the seating point on the guide rail 33 can be easily adjusted and set. In the embodiment, an example in which the hemispherical depression-shaped tilt angle setting holes 225 are provided in a total of five stages is shown, but it may be formed in a finer groove shape or in a multistage of seven or more stages. Further, such a step mechanism may be provided on the tilt angle adjusting lever 231 side.
[0079]
Therefore, according to the launch angle adjusting mechanism 200 described above, the launch angle of the game ball can be easily adjusted by swinging the tilt angle adjusting lever 231. Therefore, the ball is caused by variations in each component of the pachinko machine. Even if there is an individual difference in flying, it is possible to make the ball flying uniform by adjusting the seating point on the guide rail 33 within a certain range by adjusting the launch angle of the game ball. In addition, since the firing angle adjusting mechanism 200 is configured to lock the guide member by engaging the locking protrusion and the tilt angle setting hole, the adjusted firing angle can be stably maintained over a long period of time.
[0080]
