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]
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.

Hereinafter, first, the firing angle adjusting mechanism 100 of the first embodiment will be described with reference to FIGS.
[0019]
Here, each figure will be briefly described in advance. FIG. 2 is a front view of the launch angle adjusting mechanism 100, and FIG. 3 is an enlarged view of the positional relationship between the launch rail 23 and the game board 30 and the guide member of the launch angle adjusting mechanism. FIG. 4 is a perspective view of the launch angle adjusting mechanism 100 viewed from diagonally forward with the case cover 11 covering the front of the launch angle adjusting mechanism 100 being removed, and FIG. 5 is a perspective view of the launch angle adjusting mechanism 100 from diagonally rear. 6 and 7 are side sectional views taken along arrows VI-VI and VII-VII in FIG. 2, respectively, FIG. 8 is a plan view of the launch angle adjusting mechanism 100, and FIG. FIG. 10 is a front view for explaining the operation of the firing angle adjusting mechanism 100. FIG.
[0020]
The launch angle adjusting mechanism 100 is a game ball (hereinafter referred to as “launch ball”) B that is disposed between the launch rail 23 and the guide rail 33 and moves from the launch rail 23 toward the guide rail 33._HThe guide member 110 provided with the auxiliary rail portion 113 that guides the guide member, the guide member support boss 120 that supports the guide member 110 so as to be tiltable, and the tilt angle position of the guide member 110 supported by the guide member support boss 120. An inclination angle setting structure 130 including an expansion / contraction member 132 and a locking screw 138 that can be adjusted and set steplessly by adjusting and tightening the locking screw 138 is provided. By setting the inclination angle of the auxiliary rail portion 113, the shot ball B launched from the game ball launch device 20 onto the guide rail 33_HIt is configured so that the launch angle can be adjusted steplessly.
[0021]
The guide member 110 has an auxiliary rail portion 113 on the upper portion of the main body portion 111 forming a housing, and an inclination index portion on the lower portion. For example, the guide member 110 is formed as a single block by a molding means such as injection molding using a resin material such as ABS resin. To be molded.
[0022]
The auxiliary rail portion 113 is formed with a rail surface that extends to the left and right with substantially the same rail width as that of the launch rail 23, and the inclination angle is ± on the basis of the guide member 110 as shown in FIGS. It is formed so as to coincide with the inclination angle of the firing rail 23 in a state where the inclination angle position is set to 0 degree. 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 part 113 is formed in a curved surface that is smoothly connected to the right side wall of the main body part 111, and even when the guide member 110 is set at either the positive or negative angular position, the launch ball that passes above B_HIs smoothly guided along the auxiliary rail 113 (see FIG. 10).
[0023]
A side rail 114 is erected on the rear side of the rail surface of the auxiliary rail portion 113. The right end side of the side rail 114 is formed to protrude rightward from the side wall of the main body 111, and the protruding piece 114 a is disposed in front of the lower edge of the decorative plate 31. 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. In addition, 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. 8).
[0024]
A bearing hole 112 is formed in the upper center of the main body 111 so as to extend rearward from the front wall surface. The inner diameter of the bearing hole 112 is slightly larger than the outer diameter of the guide member support boss 120, and a counterbore hole through which the support screw 128 is inserted is formed on the front end side thereof. A screw receiving portion 115 is formed in the center of the lower portion of the main body portion 111 so as to penetrate the front and rear sides and screw and support the locking screw 138. As the locking screw 138, a threaded tip screw having a screw tip formed in a conical shape is used. The lower portion of the main body 111 is formed in a triangular flange shape that is pointed downward, and an index 117 for viewing the tilt angle setting position of the guide member 110 is formed at the tip thereof.
[0025]
On the other hand, in the game auxiliary board 10, a cylindrical guide member support boss 120 located on the left side of the upper end portion of the launch rail 23 is projected forward, and an expansion / contraction member for attaching the expansion / contraction member 132 to the lower side thereof. A mounting hole 131 is formed through the front and rear of the board surface. Further, an inclination scale 137 is provided below the expansion / contraction member mounting portion 131 at a height position matching the index 117 on the guide member side as a guide indicating the inclination angle setting state of the guide member 110. 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.
[0026]
The expansion / contraction member 132 includes a sandwiching portion 133 that is somewhat larger than the opening size of the expansion / contraction member mounting hole 131 and is formed to have a protruding height that is substantially the same as the thickness of the game auxiliary board 10, and a flange formed behind the pinching portion 133. It is formed by molding a polymer material having a high impact resilience such as rubber or polyurethane. In the central portion of the expansion / contraction member 132, a long and long elongated screw receiving groove 135 is formed penetrating the front and rear of the expansion / contraction member. The groove width of the screw receiving groove 135 is smaller than the outer diameter of the locking screw 138, and the groove length is formed in accordance with the swing range of the locking screw. The expansion / contraction member 132 is attached to the game auxiliary board 10 with a screw or the like that secures the adhesive portion or flange portion by fitting the clamping portion 133 into the expansion / contraction member attachment hole 131 from the rear surface side of the game auxiliary board 10, and the screw receiving groove 135. Is exposed and arranged on the front side of the game auxiliary board 10.
[0027]
The guide member 110 is attached to the front side of the game auxiliary board 10 so as to be positioned in front of the expansion / contraction member 132. The guide member 110 is supported by fitting a bearing hole 112 to a guide member support boss 120 projecting and molded on the front side of the game assisting board, and supporting the support screw from the counterbore hole on the front side to the screw hole in the center of the guide member support boss. By screwing 128, the guide member support boss 120 is supported so as to be tiltable to the left and right.
[0028]
Then, when the locking screw 138 is screwed into the screw receiving portion 115 of the guide member supported in this way and tightened, the tip portion of the screw tip fits into the groove of the screw receiving groove 135 of the expansion / contraction member ( 7 (see a partial enlarged view appended to FIG. 7), the clamping portion 133 is elastically deformed so as to push and spread the screw receiving groove 135 (see FIG. 7 and FIG. 9). For this reason, the locking screw 138 is locked with its distal end being sandwiched in the screw receiving groove 135, whereby the guide member 110 is locked and held at an angular position corresponding to the position where the locking screw 138 is tightened. .
[0029]
In front of the guide member 110, 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. A guard wall 15 is formed on the rear surface side of the case cover 11 and is located on the left side of the guide member 110 and extends rearward to form a side wall of the foul ball collection passage.
[0030]
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 that the angular position of the guide member 110 is not changed.
[0031]
In addition, a circular tool insertion hole 16 is formed in the case cover 11 in accordance with the arrangement position of the support screw 128 of the guide member 110, and the downward direction from the arrangement position of the locking screw 138 by the locking screw 138. An inclination setting window 17 for confirming the inclination adjustment operation and the setting state of the inclination indicated by the index 117 is formed with an opening.
[0032]
In the firing angle adjusting mechanism 100 configured as described above, the locking screw 138 is loosened to adjust the tilt angle position of the guide member 110, and the tilt angle of the auxiliary rail portion 113 is adjusted to adjust the locking screw 138. By tightening, launch ball B_HThe firing angle can be adjusted and set steplessly and fixed at the firing angle.
[0033]
When adjusting the launch angle of the game ball, the launch mechanism 21 sets the reference angle position of the guide member 110, which is the initial setting, that is, the angle position where the guide member index 117 points to the center of the tilt scale 137. This is done by setting the firing strength of the launched game ball to a reference strength and adjusting the tilt angle position of the guide member 110 so that the seated point of the launched 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.
[0034]
The game ball that is struck by the hammer of the launch mechanism 21 and launched leftward has a downward component force due to a relative action (reaction force) with the launch rail 23 that extends obliquely upward, and is therefore pressed against the launch rail 23. In this way, it rolls along the rail surface, and flies over the foul ball collection port 13 toward the launch passage 34 through the auxiliary rail portion 113.
[0035]
Here, the auxiliary rail portion 113 is provided with a side rail 114, 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.
[0036]
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. Further, when the game ball moves along a route away from the game board 30, or the game ball guided forward in contact with the side rail 114 is guided in contact with the flight guide 12 of the case cover, and the glass door 5 It flies toward the guide rail 33 without directly colliding with the glass plate.
[0037]
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 in the pachinko machine PM to determine its height. The seating point can be determined using, for example, a model-specific template or gauge that matches the board surface, or by a method of observing the contact point by attaching pressure sensitive paper to the rail surface of the guide rail 33. be able to.
[0038]
When it is determined that the observed seating point is higher than the reference seating point, the locking screw 138 located on the front surface of the tilt setting window 17 is loosened, and the guide member 110 is moved as shown in FIG. Tilt in the negative tilt direction, the tilt angle of the auxiliary rail portion 113 is changed to the launch ball B_HThe locking screw 138 is tightened by adjusting downward as viewed in the direction of travel. When the locking screw 138 is tightened, the screw tip portion is fitted into the screw receiving groove 135 of the expansion / contraction member and is sandwiched by the elastic reaction force, and the guide member 110 is in the angular position, that is, the inclination angle of the auxiliary rail portion 113. Is held at the angular position adjusted downward. Thereby, the launch ball B launched through the auxiliary rail portion 113_HThe firing angle changes downward from before the adjustment, and the seating point on the guide rail 33 becomes lower.
[0039]
On the other hand, when it is determined that the observed seating point is lower than the reference seating point, the locking screw 138 is loosened to tilt the guide member 110 in the positive tilt direction as shown in FIG. The angle of inclination of the rail part 113 is set to the launch ball B_HThe locking screw 138 is tightened by adjusting upward as seen in the direction of travel. In this case as well, the distal end portion of the locking screw 138 is inserted into the screw receiving groove 135 of the expansion / contraction member and is sandwiched by the elastic reaction force, so that the guide member 110 is in the angular position, that is, the inclination angle of the auxiliary rail portion 113. Is held at the angular position adjusted upward. Thereby, the launch ball B launched through the auxiliary rail portion 113_HThe angle of launch changes more upward than before the adjustment, and the seating point on the guide rail 33 becomes higher.
[0040]
The adjustment of the tilt angle can be performed directly using a screwdriver engaged with the locking screw 138, and by loosening the screw, a finger can be placed on the screw head of the locking screw protruding forward of the cover plate. You can also hang it. Further, as indicated by a dotted line in FIG. 2, an operation pin 118 protruding forward may be provided on the upper side of the index 117, and the adjustment operation may be performed using this operation pin. Note that after the adjustment operation is completed, the support screw 128 may be tightened to fix the angular position of the guide member 110, and the set inclination angle can be maintained more firmly.
[0041]
Further, during the adjustment operation, the position of the index 117 with respect to the tilt scale 137 serves as a guide indicating the tilt direction and the degree of the auxiliary rail portion 113, and the index with respect to the tilt scale 137 is determined according to the height and level of the observed seating point. By adjusting while referring to the position 117, the launch angle of the game ball, and thus the seating point on the guide rail 33 can be easily adjusted.
[0042]
Therefore, according to the launch angle adjusting mechanism 100 described above, the launch ball B launched onto the guide rail 33 by adjusting the tilt angle position of the guide member 110 and tightening the locking screw 138._HCan be adjusted steplessly. For this reason, even if individual differences occur in the ball flight due to variations in each component, the seating point on the guide rail 33 is finely adjusted by adjusting the launch angle of the game ball to make the ball flight uniform. be able to.

[0049]
The tilt angle setting structure 230 is mainly composed of a tilt angle adjusting lever 231 that is swingably supported by the game assisting board 10, and includes an engaging pin 235 formed on the tilt angle adjusting lever and a pin engaging groove formed on the guide member 210. 215 and the engagement relation.
[0050]
The tilt angle adjusting lever 231 includes an operation lever portion 233 that is projected from the cylindrical bearing portion 232 in the direction orthogonal to the axis, and an axis line of the bearing portion 232 that extends in the direction orthogonal to the bearing portion 232 and the operation lever portion 233. It has an engaging pin 235 protruding forward in parallel. The inner diameter of the bearing portion 232 is formed to be slightly larger than the outer diameter of the adjustment member support boss 221 on the side of the game assisting board. The inclination adjustment lever 231 is engaged with the adjustment member support boss 221 so as to be detachable. It is supported in a swingable manner.
[0051]
The engaging pin 235 has an outer diameter that is substantially the same as the groove width of the pin engaging groove 215 of the guide member. The engaging pin 235 fits in the groove width direction of the pin engaging groove 215 without any backlash. The mating grooves 215 are engaged with each other so as to be slidable relative to each other. Further, the positional relationship between the engagement pin 235 and the pin engagement groove 215 is such that the tilt angle adjusting lever 231 is supported by the adjustment member support boss 221 and the guide member 210 is supported by the guide member support boss 220 to engage with each other. Needless to say, the inter-shaft distance between the bearing portion 232 and the engagement pin 235 (that is, the rocking radius of the engagement pin 235) is the distance between the bearing hole 212 and the engagement pin 235 ( That is, it is set to be smaller than the tilting radius on the guide member side tilted by the engaging pin 235.
[0052]
On the other hand, the game assisting board 10 has a guide member support boss 220 that is located on the left side of the launch rail 23 and supports the guide member 210, and an adjustment member support boss 221 that supports the tilt adjustment lever 231 that is projected forward. Yes. On the lower side of the guide member support boss 220, an inclination scale 237 is provided as a guide indicating the inclination angle setting state of the guide member 210 at a height position matching the indicator 217 on the guide member side. 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.
[0053]
And each member comprised as mentioned above is assembled | attached to the game auxiliary | assistant board 10, and the inclination angle adjustment mechanism 200 is formed. Assembly is performed from the tilt angle adjusting lever 231, and the bearing portion 232 of the tilt angle adjusting lever 231 is fitted and supported on the adjusting member support boss 221 of the game assisting board, and the locking screw 238 is fastened from the front via the washer. Thus, the tilt angle adjusting lever 231 is swingably supported by the adjusting member support boss 221. The guide member 210 engages and supports the bearing hole 212 at the lower end of the main body portion with the guide member support boss 220, and engages the pin engagement groove 215 with the engagement pin 235 of the tilt adjustment lever, thereby guiding the guide member support boss. The support screw 228 is fastened through a washer from the front of 220 so that it can be tilted left and right.
[0054]
When the tilt angle adjusting lever 231 is swung with the tilt angle adjusting lever 231 and the guide member 210 assembled in this way, the engagement pin 235 swings up and down around the adjusting member support boss 221 as an axis. The guide member 210 engaged with the engagement pin 235 and the pin engagement groove 215 tilts left and right around the guide member support boss 220 as the axis while sliding the engagement pin 235 within the pin engagement groove 215.
[0055]
Here, as described above, the inter-axis distance between the bearing portion 232 and the engagement pin 235 is smaller than the distance between the bearing hole 212 and the engagement pin 235, that is, the swing radius of the engagement pin 235 is engaged. It is set to be smaller than the tilt radius on the guide member side tilted by the pin 235. This means that the displacement in the left-right direction of the engagement pin 235 due to the swing of the tilt angle adjusting lever 231 is transmitted to the guide member 210 as a small tilt angle displacement. In other words, the slight tilt angle of the guide member 210. This means that the change is enlarged and converted to a larger swing operation angle (operation amount), which means that a fine angle adjustment is possible.
[0056]
Therefore, the guide member 210 can be tilted left and right by swinging the tilt angle adjusting lever 231 using the operation lever portion 233, and the tilt angle position of the guide member 210 can be adjusted in adjusting the tilt angle position. It can be adjusted continuously and finely. The longitudinal dimension of the bearing portion 232 in the tilt angle adjusting lever is set to be larger than the protruding height of the adjusting member support boss 221 as shown in a partial sectional view in FIG. By tightening the locking screw 238 when the adjustment is completed, the tilt angle adjusting lever 231 can be fixed at the adjusted swing angle position, and the guide member 210 can be locked at the tilt angle position. . The bearing hole 212 in the guide member can also be configured similarly to the bearing portion 232, and the guide member 210 can be firmly fixed at the adjusted tilt angle position.
[0057]
On the other hand, on the case cover 11 attached in front of the guide member 210 and the tilt angle adjusting lever 231, the flying guide 12 similar to that described above is formed obliquely above and to the left above the extension line of the firing rail 23. A foul ball collection port 13 that opens upward is formed between the guide member 210 and the guide rail 33 at the rear thereof. 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. A guard wall 15 is formed on the rear surface side of the case cover 11 and is located on the left side of the guide member 210 and extends rearward to form a side wall of the foul ball collection passage.
[0058]
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 foul ball buffering wall 216 and the guard wall 15 of the guide member and guided to the foul ball collection passage 14 so that it does not collide with the tilt angle adjusting lever 231. ing.
[0059]
Further, the case cover 11 is formed with a substantially rectangular inclination setting window 17 on the right side of the guard wall 15 so that adjustment and fixing operation of the inclination adjustment lever 231 and visual confirmation of the inclination indicated by the index 217 can be performed. It has become.
[0060]
Now, in the firing angle adjusting mechanism 200 configured as described above, the tilting angle position of the guide member 210, that is, the tilting angle of the auxiliary rail portion 213, by loosening the locking screw 238 and swinging the tilting angle adjusting lever 231. Adjust steplessly to launch ball B_HCan be fixed to the adjusted firing angle by tightening the locking screw 238.
[0061]
When adjusting the firing angle of the game ball, the firing mechanism 21 sets the reference angular position setting of the guide member 210 that is the initial setting, that is, the angular position that the guide member index 217 points to the center of the inclination scale 237. The firing strength of the game ball to be launched is set to the 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.
[0062]
The game ball that is struck by the hammer of the launch mechanism 21 and launched leftward has a downward component force due to a relative action (reaction force) with the launch rail 23 that extends obliquely upward, and is therefore pressed against the launch rail 23. In this way, it rolls along the rail surface and flies over the foul ball collection port 213 toward the launch passage 34 through the auxiliary rail portion 213.
[0063]
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.
[0064]
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 in the pachinko machine PM to determine its height and lowness. The seating point can be determined using, for example, a model-specific template or gauge that matches the board surface, or by a method of observing the contact point by attaching pressure sensitive paper to the rail surface of the guide rail 33. be able to.
[0065]
When it is determined that the observed seating point is lower than the reference seating point, the locking screw 238 is loosened to swing the tilt adjustment lever 231 and the guide member 210 is tilted in the positive tilt direction to assist. The angle of inclination of the rail part 213 is set to the launch ball B_HThe locking screw 238 is tightened by adjusting upward as seen in the direction of travel (see FIG. 16A). When the locking screw 238 is tightened, the tilting of the guide member 210 is restricted by the engagement between the locking pin 235 and the locking groove 215, and the tilting angular position where the locking screw 238 is tightened, that is, the auxiliary rail portion 213. Is held at an angular position where the inclination angle of the is adjusted upward. Thereby, the launch ball B launched through the auxiliary rail portion 213_HThe angle of launch changes more upward than before the adjustment, and the seating point on the guide rail 33 becomes higher.
[0066]
On the other hand, when it is determined that the observed seating point is higher than the reference seating point, the locking screw 238 is loosened to swing the tilt angle adjusting lever 231 and the guide member 210 is tilted in the negative tilt direction to assist. The angle of inclination of the rail part 213 is set to the launch ball B_HThe locking screw 238 is tightened by adjusting downward as seen in the direction of travel (see FIG. 16B). When the locking screw 238 is tightened, the tilting of the guide member 210 is restricted by the engagement between the locking pin 235 and the locking groove 215, and the tilting angular position where the locking screw 238 is tightened, that is, the auxiliary rail portion 213. Is held at an angular position where the inclination angle is adjusted downward. Thereby, the launch ball B launched through the auxiliary rail portion 213_HThe firing angle changes downward from before the adjustment, and the seating point on the guide rail 33 becomes lower.
[0067]
The adjustment operation of the tilt angle can be performed continuously by swinging the operation lever portion 233 to the left and right, and the operation amount is enlarged and converted as described above. It can be done easily. In the adjustment operation, the position of the index 217 with respect to the inclination scale 237 serves as a standard indicating the inclination direction and the degree of the auxiliary rail portion 213, and the inclination scale 237 depends on the observed height and amount of the seating point. By operating the lever while referring to the position of the index 217, the launch angle of the game ball can be adjusted, and the seating point on the guide rail 33 can be easily adjusted.
[0068]
Therefore, according to the launch angle adjusting mechanism 200 described above, the launch angle of the game ball can be easily and continuously adjusted by swinging the tilt angle adjusting lever 231, resulting in variations in the components of the pachinko machine. Even if there is an individual difference in the flying of the ball, by adjusting the launch angle of the game ball, the seating point on the guide rail 33 can be finely adjusted to make the flying of the ball uniform. In addition, in the firing angle adjustment mechanism 200, the tilt angle of the guide member 210 is converted into an operation amount that is enlarged, so that the fine angle adjustment of the auxiliary rail portion 213 can be easily performed.
[0069]

A ring groove for fitting an E-ring (E-type retaining ring) 336 is formed on the tip end side of the engagement pin. The distance between the taper surface and the ring groove is substantially the same as the thickness of the wall surface on which the pin engagement groove 315 is formed, and the engagement pin 335 is fitted into the pin engagement groove 315 to form the ring groove. When the E-ring 336 is fitted, the tilt angle adjusting screw 331 is engaged in the axial direction without backlash, and a constant relative inclination is allowed by the action of the tapered surface.
[0078]
On the other hand, in the game assisting board 10, a guide member support boss 320, which is positioned on the left side of the upper end of the launch rail 23 and supports the guide member 310, is projected forward, and below that is aligned with the indicator 317 on the guide member side. An inclination scale 337 is provided as a guide indicating the setting state of the inclination angle of the guide member 310 at the height position. On the left side of the inclination scale 337, a support member fixing portion that positions and fixes and holds the support member 332 is counterbored according to the shape and dimension of the leg portion of the support member.
[0079]
And each member comprised as mentioned above is assembled | attached to the game auxiliary | assistant board 10, and the inclination angle adjustment mechanism 300 is formed. The guide member 310 is supported so as to be tiltable to the left and right by fitting the bearing hole 312 to the guide member support boss 320 and supporting it, and fastening the support screw 328 to the guide member support boss 320 from the front of the screw receiving flange 313a. The
[0080]
The tilt angle setting structure 330 is positioned at its position and orientation by fitting a support member 332 to a support member fixing portion formed in a counterbore shape on the game auxiliary board 10 and screwing the support member 332, and the support member thus positioned is positioned. By attaching the inclination adjusting screw 311 to the nut 333, the nut 333 is attached to the game auxiliary board. Then, the inclination angle adjusting screw 311 is extended so that the engagement pin 335 at the tip is fitted into the pin engagement groove 315 of the guide member 310, and the E-ring 336 is fitted on the tip of the engagement pin 335 protruding to the right side of the intermediate wall. Thus, the guide member 310 is engaged and connected.
[0081]
When the tilt angle adjusting screw 331 and the guide member 310 are engaged and connected in this manner, the tilt angle position of the guide member 310 can be adjusted by rotating the tilt angle adjusting screw 331. For example, when the tilt angle adjusting screw 331 is rotated clockwise, the tilt angle adjusting screw 331 is moved to the right according to the screwing with the nut 333 (depending on the relationship between the screw pitch and the rotating angle), and the engagement pin The taper surface on the proximal end side of 335 presses the peripheral edge of the pin engaging groove 315 to the right, tilts the guide member 310 around the guide member support boss 320, and the negative end of the auxiliary rail portion 313 is directed downward. Tilt in the direction of the tilt angle. Conversely, when the tilt angle adjusting screw 331 is rotated counterclockwise, the tilt angle adjusting screw 331 moves to the left according to the screwing with the nut 333, and the E ring 336 moves the peripheral edge of the pin engaging groove 315 to the left. Withdrawing, the guide member 310 is tilted around the guide member support boss 320 and tilted in the positive tilt angle direction in which the tip end side of the auxiliary rail portion 313 faces upward.
[0082]
Here, the relationship between the rotation angle of the tilt angle adjusting screw 331 and the tilt angle of the guide member 310 depends on the screw pitch of the tilt angle adjusting screw 331 and the length of the arm of the guide member tilted by the tilt angle adjusting screw (bearing hole 312). Even if the tilt angle adjusting screw is rotated by one pitch, the guide member 310 is tilted only by an angle obtained by dividing the pitch by the length of the arm. This means that a slight change in the tilt angle of the guide member 310 is enlarged and converted to a larger rotation operation angle (operation amount), and more specifically, a fine angle adjustment is possible.
[0083]
Therefore, the guide member 310 can be tilted to the left and right by rotating the tilt angle adjusting screw 331. In adjusting the tilt angle position, the tilt angle position of the guide member 310 is continuously and finely adjusted. Can do. The longitudinal dimension of the bearing hole 312 is set to be larger than the protruding height of the guide member support boss 320. When the adjustment of the tilt angle position of the guide member 210 is completed, the support screw 328 is tightened to guide the bearing hole 312. The member 210 can be set to be locked at the tilt angle position. In addition, a lock nut can be engaged with a screw portion 334 of an inclination angle adjusting screw protruding rightward from the support member 332 so as to face the nut 333 and the lock nut can be locked after adjusting the tilt angle position. Thus, the locking setting of the guide member 310 can be further strengthened.
[0084]
On the other hand, on the case cover 11 attached in front of the guide member 310 and the inclination adjusting screw 331, the flying guide 12 similar to that described above is formed obliquely above and to the left above the extension line of the launch rail 23. A foul ball collection port 13 that opens upward is formed between the guide member 310 and the guide rail 33 at the rear thereof. 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 passes through the foul ball collection passage 14 and is collected in the lower ball tray 7. On the back surface side of the case cover 11, a guard wall 15 is formed which is located on the left side of the guide member 310 and extends rearward to form a side wall of the foul ball collection passage.
[0085]
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 foul ball buffering wall 316 and the guard wall 15 of the guide member and guided to the foul ball collection passage 14 so as not to collide with the inclination angle adjusting screw 331. ing.
[0086]
In addition, the case cover 11 is formed with an inclination setting window 17 on the right side of the guard wall 15 so that adjustment operation using the inclination adjustment screw 331, fixing operation of the support screw 328, and visual confirmation of the inclination indicated by the index 317 can be performed. It is like that.
[0087]
Now, in the launch angle adjusting mechanism 300 configured as described above, the tilt angle position of the guide member 310, that is, the tilt angle of the auxiliary rail portion 313 is adjusted by loosening the support screw 328 and swinging the tilt angle adjusting screw 331. Steplessly adjusting the launch ball B_HCan be fixed to the adjusted firing angle by tightening the support screw 328.
[0088]
When adjusting the launch angle of the game ball, the launch mechanism 21 sets the reference angle position of the guide member 310, which is the initial setting, that is, the angle position where the guide member index 317 points to the center of the tilt scale 337. The firing strength of the game ball to be launched is set to the reference strength, and the tilt angle position of the guide member 310 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.
[0089]
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 313 toward the launch passage 34 through the rail portion 313.
[0090]
Here, the auxiliary rail portion 313 is provided with a side rail 314, and the side rail 314 is disposed in front of the lower edge of the decorative plate 31. For this reason, even if a cell stretched on the surface of the decorative board 31 is peeled off, the side rail 314 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, a game ball in which the game ball has moved along a forward path away from the game board 30 or a game ball guided forward in contact with the side rail 314 is guided in contact with the flight guide 12 of the case cover, and is moved to the glass door. It flies toward the guide rail 33 without directly colliding with the glass plate 5.
[0091]
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 in the pachinko machine PM, and the height / lowness is determined. In addition, each method mentioned above can be used for determination of a seating point.
[0092]
When it is determined that the observed seating point is higher than the reference seating point, the support screw 328 is loosened to release the locking of the guide member 310, and the tilt adjustment screw 331 is rotated clockwise to guide. The member 310 is tilted in the negative tilt direction, and the tilt angle of the auxiliary rail portion 313 is changed to the launch ball B._HThe support screw 328 is tightened by adjusting downward as seen in the traveling direction (see FIG. 22). When the support screw 328 is tightened, the guide member 310 is locked and held at the tilt angle position, that is, the angle position where the tilt angle of the auxiliary rail portion 313 is adjusted downward. Thereby, the launch ball B launched through the auxiliary rail portion 313_HThe firing angle changes downward from before the adjustment, and the seating point on the guide rail 33 becomes lower.
[0093]
On the other hand, when it is determined that the observed seating point is lower than the reference seating point, the tilt adjustment screw 331 is rotated counterclockwise, and the guide member 310 is tilted in the positive tilt direction to assist the auxiliary rail portion 313. The tilt angle of the launch ball B_HThe support screw 328 is tightened by adjusting upward as seen in the direction of travel. When the support screw 328 is tightened, the guide member 310 is locked and held at the tilt angle position, that is, the angle position where the tilt angle of the auxiliary rail portion 313 is adjusted upward. Thereby, the launch ball B launched through the auxiliary rail portion 313_HThe angle of launch changes more upward than before the adjustment, and the seating point on the guide rail 33 becomes higher.
[0094]
The tilt angle adjustment operation can be continuously performed by rotating the tilt angle adjustment screw 331 clockwise or counterclockwise, and the operation amount is enlarged and converted as described above, so that the operation amount is very small. The inclination angle can be easily adjusted. Further, during the adjustment operation, the position of the index 317 with respect to the inclination scale 337 serves as a standard indicating the inclination direction and the degree of the auxiliary rail portion 313, and the inclination scale 337 depends on the observed height and amount of the seating point. By operating the lever while referring to the position of the index 317, the launch angle of the game ball can be adjusted, and the seating point on the guide rail 33 can be easily adjusted.
[0095]
Therefore, according to the launch angle adjusting mechanism 300 described above, the launch angle of the game ball can be easily and continuously adjusted by rotating the tilt angle adjusting screw 331, which is caused by variations in each component of the pachinko machine. Even if there is an individual difference in the flying of the ball, by adjusting the launch angle of the game ball, the seating point on the guide rail 33 can be finely adjusted to make the flying of the ball uniform. Further, in the firing angle adjustment mechanism 300, the tilt angle of the guide member 310 is converted into an operation amount that is enlarged, so that the fine angle adjustment of the auxiliary rail portion 313 can be easily performed.
[0096]
In this embodiment, a pin engaging groove 315 is formed in the intermediate wall of the guide member 310, and an E ring 336 is fitted on the tip end side of the engaging pin 335 fitted in the pin engaging groove 315. Although the configuration example in which the wall is engaged is shown, the tilt angle adjusting screw 331 may be a configuration that can adjust the tilt angle position of the guide member 310. For example, a biasing means such as a spring for biasing the intermediate wall in the direction of the tilt angle adjusting screw 331 is provided while the tip of the tilt angle adjusting screw 331 is brought into contact with the intermediate wall as a round tip or a rod tip. A configuration in which the guide member 310 tilts according to the screwing can also be adopted.
[0097]
