Description

  The present invention relates to an attachment technique for attaching a pachinko gaming machine to a gaming machine installation base unit generally called an “island”, and more particularly to an attachment technique that makes it possible to easily adjust the inclination of the pachinko gaming machine.

  The pachinko gaming machine is used in a state of being attached to a gaming machine installation base unit generally called “island”, more specifically, for example, a wooden frame provided on “island”. Since pachinko machines are quite heavy, it is usually fixed.

On the other hand, in pachinko machines, it is essential to manage the adjustment of the ball.
In general, the adjustment of the ball necessary for such management is performed by adjusting a large number of nails erected on the board surface of the pachinko machine. However, skill and intuition based on many years of experience are indispensable for adjusting such nails, and it is not something that anyone can do.

  By the way, the adjustment of the ball in the pachinko machine can be performed without the adjustment of the nail as described above. That is, such an adjustment can be performed by giving a proper inclination to the pachinko gaming machine with the nail fixed. In other words, the closer the angle of the pachinko gaming machine is to the horizontal, the more often the ball gets entangled with the nail. Therefore, if the inclination angle of the pachinko gaming machine is reduced, the influence of the nail will greatly affect the movement of the ball. Using these properties, the same effect as when nails are adjusted is much simpler than when nails are adjusted by giving an appropriate inclination when attaching a pachinko machine to the frame. Will be obtained. In addition, if it is possible to adjust the inclination angle after the fact, the convenience is greatly improved.

Based on such knowledge, the inventor of the present application has been conducting research since then. For example, an attachment device for a pachinko gaming machine disclosed in JP-A-10-080563 has been devised.
The pachinko gaming machine mounting device includes a first member fixed to an upper portion of the frame of the pachinko gaming machine mounting unit, an upper portion of the pachinko gaming machine, and a front and rear direction of the pachinko gaming machine. And a second member fixed to the first member with an arbitrary relative position to the first member. The pachinko gaming machine is framed with an arbitrary inclination angle. It can be fixed to. In other words, the relative positional relationship of the second member with respect to the first member can be changed so that appropriate positioning is possible, so that the pachinko gaming machine can be attached to the frame body with an appropriate inclination. At the same time, the angle of inclination can be changed afterwards.

Although this pachinko machine mounting device is very convenient, it is not without any points to be improved.
That is, it is easy to grasp the relative position of the first member and the second member, but it is difficult to grasp the absolute inclination angle of the pachinko gaming machine at that time. That is, the first member when the first member is attached to the pachinko gaming machine installation base unit, the positional relationship between the pachinko gaming machine installation base unit, and the second member when the second member is attached to the pachinko gaming machine, pachinko machine Since the positional relationship between the gaming machines is not always constant, the relative positions of the first member and the second member in the initial state also inevitably vary. Under such circumstances where the initial state is not constant, no matter how the relative positional relationship between the first member and the second member is detected, the relative positional relationship between the pachinko gaming machine installation base unit and the pachinko gaming machine is unambiguous. Therefore, it is very difficult to accurately determine the inclination angle of the pachinko gaming machine by determining the positional relationship between the first member and the second member.
In order to eliminate variations in the mounting position when attaching the first member to the pachinko gaming machine installation base unit and variations in the mounting position when attaching the second member to the pachinko gaming machine, for example, mounting of the first member, second The attachment of one of the members may be performed, and the other may be attached after performing accurate alignment so that the relative position between the two is constant. In this way, the initial relative position of both can be made constant.
However, performing such a cumbersome procedure is not a very reasonable solution. In addition, the attachment device for the pachinko gaming machine needs to be installed in a very narrow portion on the back side of the pachinko gaming machine, and it is difficult to execute the above-described operation for positioning itself. .

  The present invention provides a pachinko gaming machine comprising a first member fixed to a frame and a second member fixed to the pachinko gaming machine and fixed to the first member with an arbitrary relative position to the first member. It is an object of the present invention to improve the mounting apparatus of the above so that the absolute inclination angle of the pachinko gaming machine at that time can be easily grasped.

The present invention for solving this problem is as follows.
The invention of the present application is fixed to the upper part of the frame of the pachinko gaming machine installation base unit, fixed to the upper part of the pachinko gaming machine, and can be translated in the front-rear direction of the pachinko gaming machine. A pachinko gaming machine comprising: a second member configured to give an appropriate inclination angle to the pachinko gaming machine by being fixed to the first member with an arbitrary relative position to the first member The basic mounting device. And it is equipped with the adjustment means which can adjust the inclination of a pachinko gaming machine in the state where all of the frame and the first member, the pachinko gaming machine and the second member, and the first member and the second member are fixed. It is characterized by that.
The attachment device for the pachinko gaming machine can adjust the inclination of the pachinko gaming machine with the frame and the first member, the pachinko gaming machine and the second member, and the first member and the second member all fixed. Adjustable means are provided. Therefore, even if accurate positioning is not performed, the first member is attached to the pachinko gaming machine mounting table unit, or the second member is attached to the pachinko gaming machine, so that the initial relative position between the first member and the second member is Even if it deviates from the preferred one, the variation can be canceled afterwards by appropriately operating the adjusting means described above.
Therefore, by using this pachinko gaming machine mounting device, it becomes easy to grasp the absolute inclination angle of the pachinko gaming machine at that time without increasing the complexity of performing the mounting work.

Here, the adjusting means described above may adjust the inclination of the pachinko gaming machine with the frame and the first member, the pachinko gaming machine and the second member, and the first member and the second member all fixed. Any configuration can be used as long as it is possible. For example, the adjusting means adjusts the relative position of the first member fixed to the frame body in the front-rear direction with respect to the frame body, or the second member fixed to the pachinko gaming machine in the front-rear direction with respect to the pachinko gaming machine. It may be configured to perform at least one of adjusting the relative position.
The 1st member should just be fixed to the upper part of the frame of a pachinko game machine installation stand unit. The second member is fixed to the upper part of the pachinko gaming machine and is movable in the front-rear direction of the pachinko gaming machine, and is fixed to the first member with an arbitrary relative position to the first member. Anything is fine. The 1st member and the 2nd member do not ask | require the specific structure, as long as this condition is satisfy | filled.
For example, the above-mentioned second member can be translated in the front-rear direction of the pachinko gaming machine and fixed to the first member at an arbitrary position, and the moving member and the pachinko gaming machine are fixed. And the adjusting means described above can be provided between the moving member and the fixing member.
In this case, the second member and the adjustment member can be as follows. In other words, the second member may have a base end portion that is threaded on the outer periphery thereof and a bolt portion that extends in the front-rear direction of the pachinko gaming machine. Further, the adjustment member is provided with a nut portion threaded on the inner periphery thereof, and is supported by the fixing member as being rotatable in a state where the bolt portion is screwed to the nut portion. Can do. Then, the initial position can be adjusted by rotating the adjusting member and moving the second member in the front-rear direction of the pachinko gaming machine.
Moreover, a 2nd member, a fixing | fixed part, and an adjustment member can be comprised as follows. That is, the base end portion of the moving member is threaded on the outer periphery thereof and is a bolt portion extending in the front-rear direction of the pachinko gaming machine, and the adjusting member is threaded on the inner periphery thereof. It is formed in a substantially cylindrical shape having a nut portion as an inner hole, and is provided with a groove portion that does not reach the nut portion and has an annular shape on its outer periphery, and the fixing portion is The adjustment member is provided with two protrusions at the tip thereof that are wider than the inner diameter of the groove and smaller than the outer diameter, and is inserted into the target position of the groove so as to be rotatable. Further, the inclination of the pachinko gaming machine may be adjusted by rotating the adjusting member and moving the second member in the front-rear direction of the pachinko gaming machine.

  Hereinafter, a preferred embodiment of a pachinko game machine mounting apparatus according to the present invention will be described with reference to the drawings.

A pachinko gaming machine mounting apparatus according to an embodiment of the present invention fixes a gaming machine installation base unit U and an outer peripheral frame F (see FIG. 1) surrounding the upper, lower, left, and right sides of the pachinko gaming machine P. is there.
More specifically, the gaming machine installation base unit U includes an upper frame body Us and a lower frame body Ud. On the other hand, the outer peripheral frame F includes an upper member Fu, a lower member Fd, a right member, and a lower member (both not shown), and is configured by assembling them into a rectangle. The pachinko gaming machine P is fixed inside the outer peripheral frame F. The attachment device for a pachinko gaming machine connects the upper frame body Us of the gaming machine installation base unit U thus configured and the upper member Fu of the outer peripheral frame F.

  FIG. 2 shows a state in which the upper frame body Us of the gaming machine installation base unit U and the upper member Fu of the outer peripheral frame F are fixed by the connecting device according to the present embodiment.

  The attachment device A includes a holding block 2 and a rack member 3, and further includes an adjustment tool 4 shown in FIGS. The attachment device A includes a fixing member 5 and a position adjusting member 6.

The holding block 2 forms the core of the first member in the present invention, and is configured as shown in FIGS. 3 to 8 (particularly, FIGS. 3 and 4), for example.
The holding block 2 in this embodiment is formed using, for example, a solid metal block body or the like, and a rack holding hole 16 having a cross-sectional shape corresponding to a cross-sectional shape of a rack member 3 described later is penetrated. In addition, an adjustment hole 17 that is orthogonal to the rack holding hole 16 and overlaps with a thickness of a rack tooth in a rack member 3 to be described later is penetrated at an intersection with the rack holding hole 16. The adjusting hole 17 is provided for inserting the adjusting tool 4 described later. The adjusting hole 17 is provided with a positioning groove 18 on the inner peripheral surface in the longitudinal direction. A stopper projection 19 projects from the opening end of the adjustment hole 17 so as to correspond to the position where the positioning groove 18 is formed.

  The holding block 2 also includes a lock portion 21 as shown in FIGS. 5 to 8, for example. The lock part 21 fixes the rack member 3 that can move relative to the holding block 2 in an appropriately positioned state.

The lock portion 21 of the attachment device A is configured by incorporating into the holding block 2 an engaging body 22 and a pressing bolt 25 that presses the engaging body 22 by engaging with a screw hole formed in the holding block 2. . The engaging body 22 brought into contact with the tip of the pressing bolt 25 has a circular main body portion and a claw portion 22t that can be engaged with rack teeth.
The lock portion 21 includes a compression coil spring 501, an upper ratchet 502, a lower ratchet 503, and a slide plate 504.
On the upper surface of the holding block 2, a cylindrical portion 505 having an inner hole 505A having a polygonal cross section is provided. The inner hole 505A in this example has an octagonal cross section.
A lower hole 506 having a slightly smaller diameter than the inner hole 505A is provided below the inner hole 505A. Inside, a fixing nut 507 having a through hole whose inner surface is threaded so as to be screwed with the pressing bolt 25 is fixedly attached.

  The above-described upper ratchet 502 and lower ratchet 503 have the same shape. FIG. 6 shows the shape of the lower ratchet 503. Both the upper ratchet 502 and the lower ratchet 503 are plate-like members having a cross-section (an octagon in this example) that fits into the inner hole. Both the upper ratchet 502 and the lower ratchet 503 have two octagonal surfaces. One surface thereof is provided with ratchet teeth 502A and 503A extending in the radial direction, and the other surface is provided with hexagonal cross section receiving holes 502B and 503B. Further, through holes 502C and 505C penetrating the upper ratchet 502 or the lower ratchet 503 are formed in the centers of the receiving holes 502B and 505B that coincide with the center of the upper ratchet 502 or the lower ratchet 503. The upper ratchet 502 or the lower ratchet 503 rotates only in one direction when the ratchet teeth 502A and 503A are engaged with each other.

  The slide plate 504 is, for example, as shown in FIG. The slide plate 504 in this example is formed by bending a rectangular metal plate approximately 90 degrees in parallel with the short side at a portion adjacent to both short sides. The slide plate 504 is provided with a substantially keyhole-like hole formed of a substantially circular circular hole 504A and a substantially elliptical small hole 504B connected to the circular hole 504A.

Further, the pressing bolt 25 of the lock portion 21 is as shown in FIG. The pressing bolt 25 has a knob on its head, is formed in a wing nut shape, and has a hexagonal section nut 25A fixedly attached immediately below the head.
The cross-sectional shape of the nut 25A is adapted to fit into the receiving hole 502B of the upper ratchet 502, and passes through the circular hole 504A of the slide plate 504, but does not pass through the small hole 504B.

The compression coil spring 501, the upper ratchet 502, the lower ratchet 503, and the slide plate 504 are combined as shown in the schematic diagram of FIG.
The upper ratchet 502 and the lower ratchet 503 are arranged with the ratchet teeth 502A and 503A facing each other. The lower ratchet 503 is inserted into the inner hole 505A of the cylindrical portion 505. Since the lower ratchet 503 has a size corresponding to the inner hole 505A, the lower ratchet 503 can slide up and down in the inner hole 505A, but its rotation is restricted by the inner surface of the inner hole 505A.
A compression coil spring 501 is disposed below the lower ratchet 503. The lower end of the compression coil spring 501 is restricted by a step formed at the connection portion between the inner hole 505A and the lower hole 506, and the upper ratchet 503 is always urged upward at the upper end portion. Due to this urging force, the ratchet teeth 502A and 503A are always subjected to an urging force in the meshing direction.
A slide plate 504 is placed on the upper ratchet 502.
The pressing bolt 25 passes through the circular hole 504A or small hole 504B of the slide plate 504 and the through holes 502C and 505C of the upper ratchet 502 and the lower ratchet 503, and is screwed into the through hole of the fixing nut 507. The inner hole 505A and the lower hole 506 are inserted. The pressing bolt 25 presses the engagement body 22 at the lower end thereof.

The lock unit 21 takes two states as shown in (a) and (b) of FIG.
In the state shown in FIG. 5A, the pressing bolt 25 is in a state of penetrating the circular hole 504A of the slide plate 504. In this state, the nut 25 </ b> A of the pressing bolt 25 passes through the circular hole 504 </ b> A of the slide plate 504 and fits with the receiving hole 502 </ b> B of the upper ratchet 502.
In this state, when the pressing bolt 25 is rotated in either direction, the upper ratchet 502 and the lower ratchet 503 also try to rotate simultaneously. Here, the lower ratchet 503 cannot be rotated due to the restriction by the inner surface of the inner hole 505A.
Incidentally, as described above, the upper ratchet 502 is rotatable only in one direction with respect to the lower ratchet 503. Therefore, when the pressing bolt 25 is rotated in that direction, the lower ratchet 502 is pushed downward against the inelastic force of the compression coil spring 501. That is, when the pressing bolt 25 is rotated in a direction in which the upper ratchet 502 is allowed to rotate in relation to the lower ratchet 503, the pressing bolt 25 can be rotated. In the lock portion 21, the direction in which the upper ratchet 503 is allowed to rotate due to the relationship with the lower ratchet 503 coincides with the direction when the pressing bolt 25 is tightened.
That is, in the state (A), the pressing bolt 25 can be rotated in the tightening direction.
On the other hand, even if it is attempted to rotate the pressing bolt 25 in the direction in which the rotation of the upper ratchet 503 is restricted in relation to the lower ratchet 503, the pressing bolt 25 does not rotate. That is, the lower ratchet 503 that cannot be rotated due to the restriction by the inner surface of the inner hole 505A is restricted, and the upper ratchet 502 cannot be rotated. The pressing bolt 25 in which the nut 25 </ b> A is fitted in the receiving hole 502 </ b> B of the upper ratchet 502 cannot be rotated by the upper ratchet 502 being restricted from rotating.
Therefore, in this state (A), the pressing bolt 25 rotates only in the direction in which it is tightened. This state is used when the rack member 3 is fixed as it is in an appropriately positioned state with respect to the holding block 2 because the press bolt 25 is not allowed to loosen.
Next, the state shown in FIG. In this state, the pressing bolt 25 is in a state of passing through the small hole 504B of the slide plate 504. In this state, the nut 25 </ b> A of the pressing bolt 25 does not fit into the receiving hole 502 </ b> B of the upper ratchet 502 due to the interference of the slide plate 504.
Since the pressing bolt 25 in this state is not restricted by the upper ratchet 502, the pressing bolt 25 can be rotated in either the tightening direction or the loosening direction.
This (b) state is used when adjusting the tightening amount of the pressing bolt 25 or when releasing the pressing of the engaging body 22.
The rack member 3 is fixed at an appropriate position with respect to the holding block 2 by appropriately using the states (a) and (b) as described above by the parallel movement of the slide plate 504. Easy release can be realized. This facilitates the setting of the inclination angle and the subsequent change of the pachinko gaming machine P.

The holding block 2 is coupled to the mounting member 1. The attachment member 1 is for fixing the holding block 2 to the upper frame body Us of the gaming machine installation base unit U in a fixed manner.
The attachment member 1 is formed by bending a metal plate, for example. As shown in FIG. 1, FIG. 9 and FIG. 10, the attachment member 1 has a rectangular elongated main body 1A, and a rib 1B formed by bending an edge along the longitudinal direction of the main body 1A. Three screw holes 1C provided along the longitudinal direction of the main body 1A, a locking portion 1D formed by punching a part of the main body 1A into an acute isosceles triangle, and one end of the main body 1A are bent. And a mounting portion 1C formed by doing so. The attachment portion 1C has a long hole 1E as shown in FIG.
As shown in FIG. 2, the attachment member 1 has three bolts 1F, which penetrate the upper frame body Us of the gaming machine installation base unit U, passed through the screw holes 1C. In this state, each bolt 1F The upper frame body Us is fixed by screwing a nut (not shown) to the tip of the frame. The attachment member 1 is fixed to the block 2 by screwing a bolt (not shown) penetrating the long hole E into a screw hole (not shown) formed in the holding block 2. In this way, the attachment member 1 fixes the frame body Us and the block 2.
In this embodiment, the 1st member in the present invention is constituted by holding block 2 and a series of composition including attachment member 1 for attaching holding block 2 to frame Us.

The rack member 3 corresponds to a moving member of the present invention, and is attached to the above-described holding block 2 in a state in which it can be translated in the front-rear direction of the pachinko gaming machine P. It is fixed after changing the angle.
The rack member 3 is provided on the front end side (right side in the figure) of the rack portion 3a having a elliptical cross-sectional shape and having rack teeth 29 having a predetermined pitch formed on the upper surface thereof, and on the base end side thereof. By being threaded on the outer periphery, a bolt portion 3b having a male screw structure is provided. Moreover, the rack member 3 includes a groove-shaped storage chamber 33 (FIG. 3) at the tip side portion of the rack portion 3a. A stopper claw 34 is provided inside the storage chamber 33. The stopper claw 34 supports its base end portion so as to be rotatable by a pin 34p, so that its distal end side freely rotates downward due to its own weight. By this downward rotation, its distal end side is rack member 3. It is made to protrude from the outer periphery.

  The fixing member 5 is for fixing the base end portion of the rack member 3 and the upper member Fu of the outer peripheral frame F. Strictly speaking, the fixing member 5 is configured to indirectly fix the rack member 3 to the upper member Fu via the position adjusting member 6.

  The fixing member 5 is configured as shown in FIGS. 2, 11, and 12. That is, the fixing member 5 includes a rectangular fixing surface 5A that is brought into close contact with the lower surface of the upper member Fu, and a bifurcated sandwiching portion 5B that is bent at one end and formed perpendicular to the fixing surface 5A. Has been. This clamping part 5B is equivalent to the protrusion of this invention. The fixing surface 5A is provided with three screw holes D along the longitudinal direction for passing through the screws 5C for fixing the fixing member 5 to the upper member Fu.

The position adjusting member 6 includes a front end portion 6A and a rear end portion 6B formed in a hexagonal cross section. The front end portion 6A and the rear end portion 6B are coaxially connected by an intermediate portion 6C having a circular cross section. The outer diameter of the intermediate part 6C is made to correspond to the interval of the above-mentioned sandwiching part 5B, and the diameters of the front end part 6A and the rear end part 6B are larger than the smallest part. . The position adjusting member 6 is supported by the fixing member 5 by inserting the intermediate portion 6C between the sandwiching portions 5B. Since the intermediate part 6C is formed in a circular cross section, the position adjusting member 6 can be rotated around its longitudinal axis by rotating the front end part 6A or the rear end part 6B using, for example, a spanner. It is like that. Further, the position adjustment member 6 is restricted from moving in the axial direction due to the above-described relationship regarding the diameters of the front end portion 6A, the rear end portion 6B, and the intermediate portion 6C and the interval between the clamping portions 5B.
The position adjusting member 6 includes a nut portion 6D. The nut portion 6D is coaxial with the central axes of the front end portion 6A, the rear end portion 6B, and the intermediate portion 6C, and the inner peripheral surface thereof is threaded.
The nut portion 6D corresponds to the bolt portion 3b described above, and the bolt portion 3b is screwed to the nut portion 6D.
A leaf spring 6E can be disposed in the gap between the intermediate portion 6C and the clamping portion 5B as shown in the figure. In this way, when a large force is applied in the front-rear direction of the pachinko gaming machine P, the force can be absorbed by the leaf spring 6E, so that the mounting device, in particular, the rack member 3 can be prevented from being damaged. become.
Here, it is also possible to attach an O-ring between the front leaf spring 6E and the front end portion 6A, or between the rear leaf spring 6E and the rear end portion 6B. By providing the O-ring, the swinging of the rack member 3 around the intermediate portion 6C becomes easier to perform, so that the possibility of the rack member 3 being damaged can be further reduced.

  With the configuration as described above, the screwing amount of the bolt portion 3b into the nut portion 6D can be appropriately adjusted by rotating the position adjusting member 6. Here, the relative position of the position adjusting member 6 to the fixing member 5 and the relative position of the fixing member 5 to the upper member Fu are both fixed. Therefore, in this attachment apparatus, the relative position in the length direction of the rack member 3 with respect to the upper member Fu of the rack member 3 can be appropriately changed by appropriately rotating the position adjusting member 6. The relative position change with respect to the upper member Fu of the rack member 3 makes it possible to adjust the initial position.

  Although the adjustment tool 4 of this embodiment is not restricted to this, For example, it has a structure as shown in FIG. The adjuster 4 includes a shaft portion 35 and an operation portion 36. The shaft portion 35 is formed by a shaft member 39 fixedly connected to a rotary drum 37 in the operation portion 36 described later by a pin 38 (FIG. 14). Specifically, the shaft member 39 is provided with a small-diameter portion 39s and a large-diameter portion 39w, and pinion teeth 41 are formed on the entire surface of the large-diameter portion 39w. It is configured to be 35. The shaft portion 35 is provided with a positioning protrusion 42 in the vicinity of the tip thereof. As shown in FIG. 14, the positioning protrusion 42 holds the spherical body 44 at the front end of the accommodation hole 43 formed in the shaft portion 35 so as to be able to protrude and retract by urging the compression coil spring 45.

  As shown in FIG. 14, the operation part 36 includes an outer peripheral frame 46 and a rotating drum 37. The outer peripheral frame 46 has a structure in which a disk-shaped side plate 48 is combined with one end side of a cylindrical outer peripheral tube 47. The outer peripheral cylinder 47 has a flat portion 49 (FIG. 14) formed in a groove shape on the inner peripheral surface, and has inner peripheral spline teeth 51 on the entire surface excluding the flat portion 49. (FIG. 16). On the other hand, the side plate 48 is provided with a guide hole 52 sized so as to be able to support the small-diameter portion 39 s of the shaft member 39 so as to be slidable, and is attached close to the guide hole 52. 53a and 53b are provided as a left-right pair (FIG. 17). And the latching protrusion 54 (FIG. 13, FIG. 14) can selectively be attached to either of these both attachment holes 53a, 53b. The distance between the mounting holes 53a and 53b corresponds to the width of the stopper projection 19 in the holding block 2. In this embodiment, specifically, the relationship between the width W of the stopper projection 19, the center interval S between the mounting holes 53 a and 53 b, and the radius r of the locking projection 54 is S−2r≈W. is there.

  The rotating drum 37 is formed in a cylindrical shape. The outer periphery of the rotary drum 37 is divided into a spline forming portion where the outer peripheral spline teeth 55 are formed and a non-spline forming portion where the diameter is slightly smaller than this and no spline teeth are formed. The outer peripheral spline teeth 55 provided at the spline forming portion mesh with the inner peripheral spline teeth 51 of the outer peripheral cylinder 47 (FIG. 16). On the other hand, a key projection 56 is provided at the non-spline forming portion. Similar to the positioning protrusion 42 in the shaft portion 35, the key protrusion 56 holds a sphere 58 arranged at the tip of the accommodation hole 57 so as to be able to protrude and retract by being biased by the compression coil spring 59.

  The rotating drum 37 and the outer peripheral frame 46 are combined so that the rotating drum 37 can move back and forth in a state where the outer peripheral spline teeth 55 of the rotating drum 37 mesh with the inner peripheral spline teeth 51 of the outer peripheral cylinder 47. A compression coil spring 60 is interposed between the rotary drum 37 and the outer peripheral frame 46, and the rotary drum 37 is urged in the backward direction by the compression coil spring 60. Further, as shown in FIG. 18, the outer peripheral frame 46 is provided with an inclination scale 61, while the rotating drum 37 is provided with a mark indicating a scale value selected from the inclination scale 61, for example, an arrow mark 62. . Although not limited to this, the inclination scale 61 in this embodiment is a scale according to the shank pendulum method conventionally used in the pachinko industry as the inclination angle of the pachinko gaming machine.

This pachinko machine mounting apparatus is used, for example, as follows.
In using the attachment device for the pachinko gaming machine, first, the holding block 2 is fixed to the upper frame body Us of the gaming machine installation base unit U via the attachment member 1, and the rack holding hole 16 of the holding block 2 is used. The rack member 3 is inserted into the rack member 3 to support the rack member 3. At this time, as shown in FIG. 3, the positional relationship between the fixing member 5 and the holding block 2 is such that the lower end of the stopper claw 34 comes into contact with the holding block 2, and the rack member 3 does not move to the pachinko gaming machine P side. Like that.
Next, the bolt portion 3 b of the rack member 3 is screwed into the nut portion 6 </ b> D of the position adjusting member 6.
Next, the clamping portion 5B is inserted between the leaf springs 6E, and the fixing member 5 is fixed to the upper member Fu in this state.

After fixing as described above, the position adjusting member 6 is appropriately rotated using a spanner or the like. As a result, the length of the bolt 3b of the rack member 3 screwed to the nut portion 6D of the position adjusting member 6 changes, and the rack member 3 moves back and forth (in the front-rear direction in FIG. 2). Moving.).
Here, the position adjustment of the rack member 3 by the rotation of the position adjustment member 6 is performed as follows.
In this embodiment, the inclination scale 61 has a standard inclination in the pachinko industry. The upper part of the pachinko gaming machine is retracted behind the lower side, that is, 13.5 mm inside the island. With the arrow mark 62 pointing to the (backward inclination), as shown in FIG. 17, the positioning protrusion 42 of the shaft portion 35 is attached so as to come to an intermediate point between the mounting holes 53a and 53b.
In this state, the position adjusting member 6 is rotated, and as a result, the inclination of the pachinko gaming machine P is set to be 4/5. In this way, the initial relative position between the holding block 2 and the rack member 3 is determined at an appropriate position.

The adjustment tool 4 is used to adjust the inclination of the pachinko gaming machine P in a state where the attachment device A is attached and the initial relative position is adjusted as described above.
Specifically, the adjustment tool 4 is first set. That is, the operation unit 36 is adjusted so that the rotational relationship of the rotary drum 37 with respect to the outer peripheral frame 46 corresponds to the intended inclination. For this purpose, the rotary drum 37 is pushed into the state shown in FIG. 15 against the bias of the compression coil spring 60. In this state, the outer peripheral spline teeth forming portion of the rotating drum 37 corresponds to the position of the flat portion 49, and therefore the meshing of the outer peripheral spline teeth 55 with the inner peripheral spline teeth 51 is released, and the rotating drum 37 is freely rotated. be able to. Using this state, the rotary drum 37 is rotated by a necessary angle. During this rotation, the key projection 56 repeatedly engages and disengages with the inner peripheral spline teeth 51, whereby the rotation operation of the rotary drum 37 can be performed at the spline tooth pitch. The necessary angle is set by aligning the arrow mark 62 on the rotary drum 37 with the tilt scale 61 on the outer peripheral frame 46. For example, when the inclination is decreased from the standard inclination setting of 4/5 mm to 3/5/5, the arrow mark is adjusted to the target scale value of 3/5/5 (indicated by a two-dot chain line in FIG. 10). . Further, in this case, the adjustment tool 4 is rotated as shown by the arrow in FIG. 17, so that the locking projection 54 is attached to the right mounting hole 53a as seen in the state of FIG. If the inclination is increased from 4/5, the rotation direction of the adjuster 4 is reversed, and the locking projection 54 is attached to the left mounting hole 53b.

  When the above adjustment is completed, the shaft portion 35 of the adjustment tool 4 is inserted into the adjustment hole 17 of the holding block 2 until the stopper projection 19 comes into contact with the operation portion 36 or the locking projection 54 comes into contact with the holding block 2. . This insertion is performed so that the positioning protrusion 42 of the shaft portion 35 extends along the positioning groove 18 of the adjustment hole 17, that is, the positioning protrusion 42 fits into the positioning groove 18. Then, the stopper claw 34 of the rack member 3 is retracted to perform an operation that enables the rack member 3 to advance. That is, the stopper claw 34 protrudes by its own weight when the inclination is larger than 4 minutes and 5 mm, and the tip of the stopper claw 34 abuts against the holding block 2 when the inclination is 4 minutes and 5 mm, so that the rack member 3 moves forward. Therefore, an operation to cancel this state is performed. When the rack member 3 can be moved forward in this way, the adjustment tool 4 is rotated until the locking projection 54 contacts the stopper projection 19 of the holding block 2. Then, since the rack member 3 moves forward by the amount corresponding to this rotation, the rack member 3 is fixed by tightening the lock member 21 at that position. As a result, the pachinko gaming machine P is set to have an inclination of 3 minutes and 5 inches.
