As shown in FIG. 11, a leaf spring 23 is provided. Further, a small circular positioning hole 24 is formed in the upper right edge of the game board 10 by cutting, and a number of nail holes are drilled in the gaming area 13 with the positioning hole 24 as a reference. By forming the game nail 14 by machining and fixing the game nail 14 to the nail hole, the positioning hole 24 and the plurality of game nails 14 can be positioned with high precision and accuracy with respect to the positioning hole 24. ing.

  A loose clip 25 is rotatably attached to the upper edge of the side frame member 21c. Further, a concave portion 26 is formed in the side frame member 21d, and a substantially oval engagement hole 27 penetrating to the back side of the game board 10 is formed in the concave portion 26. Also, cross-shaped reference marks 28a and 28b are displayed on the front surface near the upper edge of the side frame member 21c and on the front surface of the side frame member 21d, respectively. The side frame members 21a and 21b are attached to attachment holes (not shown) cut with the positioning hole 24 as a reference. Therefore, the reference marks 28a and 28b can be positioned with high accuracy with respect to the positioning hole and the nail holes.

On the other hand, the entire circumference of the transparent plate 40 is surrounded by a plastic holding frame 42. The nail position display sheet 90 displays the normal position of the game nail 14 by printing a nail position mark 92 on the surface of the transparent sheet 91. Each nail position mark 92 is represented by a golden or similar yellow circle similar to the nail head of the game nail 14, and the outer diameter of the circle is smaller than the outer diameter of the nail head of the game nail 14. 2.2 mm. In addition, cross-shaped reference marks 93a and 93b that serve as a reference for the position of each nail position mark 92 are displayed on the upper right and lower left sides of the nail position display sheet 90 by printing.
A model name 94 is printed on the lower edge of the nail position display sheet 90. Further, a hologram-type forgery prevention label 95 is attached to the lower edge portion of the nail position display sheet 90 so that the nail position display sheet 90 is not easily forged by a copying machine.
The nail position display sheet 90 is affixed to the surface of the transparent plate 40 as shown in FIG. 3, FIG.

Next, the configuration of the position adjusting means provided on the holding frame 42 will be described. The position adjusting means includes a loose fitting portion 43, a lock portion 44, and an alignment mechanism 45. First, the loose fitting portion 43 will be described as shown in FIG. The holding frame 42 and the transparent plate are formed by integrally forming hook-shaped pieces 43a and 43b whose front end portions are bent in an L-shape and loosely fitting the hook-shaped pieces 43a and 43b into the loose fitting holes 22a and 22b. 40 is supported so as to be finely movable up and down and left and right with respect to the game board 10, and the transparent plates 40 are held on the front surface of the game board 10 at regular intervals by pressing the hook-like pieces 43 a and 43 b by the leaf springs 23. It is to be done.
As shown in FIGS. 3 and 9, the lock portion 44 is a hanging portion having a U-shaped horizontal section that can be loosely fitted in the recessed portion 26 of the game board 10 toward the right side toward the lower side of the holding frame 42. 46 is formed, and a vertically long hole 47 and a wedge-shaped portion 49 having a circular arc when viewed from the front are formed in the hanging portion 46 so that the lock piece 48 can be attached to the vertically long hole 47 as shown in FIG. ing. The lock piece 48 is formed by integrally forming a hook-shaped knob portion 48b at the front end of the shaft portion 48a inserted through the vertically long hole 47 and integrally forming an orthogonal engagement portion 48c at the rear end. Become.

Further, the alignment mechanism 45 is fixed by screws 50 a to 50 c toward the right side toward the upper side of the holding frame 42. Further, a plate-like stopper piece 51 is formed integrally with the holding frame 42 in the vicinity of the right side of the alignment mechanism 45.
Next, the configuration of the alignment mechanism 45 will be described in detail with reference to FIGS. The alignment mechanism 45 is formed by inserting the screws 50a to 50c and the screws 54a and 54b into the case 52 and the lid 53, thereby fixing the case 52 and the lid 53, as shown in FIG. In this way, a support shaft 55 that can be fitted into the positioning hole 24 is projected on the back surface of the case 52, and a left-right movement dial 56 for finely moving the support shaft 55 left and right is formed on the lid 53. A vertical movement dial 57 that is exposed to the front surface from the hole 56 a and finely moves the support shaft 55 up and down is exposed to the front surface from a dial hole 57 a formed in the lid 53. The left and right moving dial 56 has a worm 56c fixed to the lower end portion of the dial shaft 56b. The dial shaft 56b is rotatably supported by vertically inserting the dial shaft 56b into a bearing portion 52a formed in the case 52, and the worm A worm wheel 56d meshing with 56c is rotatably supported by a support shaft 52b formed on the case 52, and a pinion 56e is integrally formed on the worm wheel 56d. Note that the tip of the support shaft 55 is tapered so that it can be easily fitted into the positioning hole 24.

  Further, as shown in FIG. 6, the left and right moving assembly 63 is assembled by inserting the screws 62a and 62b through the molding members 61a and 61b. The left and right moving assembly 63 is formed with a slit-like guide hole 52c that is long in the horizontal direction in the case 52, and slidably penetrates the protruding edge 63b formed on the back surface of the molding member 61b into the guide hole 52c. By being inserted, the case 52 is provided so as to move only in the left-right direction. Further, as shown in FIG. 7, rack teeth 63c are integrally formed at the lower edge of the molding member 61b, and the rack teeth 63c are engaged with the pinion 56e.

Further, a dial shaft 57b is fixed to the vertical movement dial 57 with an E-ring 57 ', and the vertical movement dial 57 is rotated by horizontally inserting the dial shaft 57b into a bearing portion 61d formed on the molding member 61a. The worm wheel 57c is fixed to the tip of the dial shaft 57b, and a worm wheel 57e integrally formed with a pinion 57d is rotatably supported on the support shaft 61c formed on the molding member 61b. 57e is meshed with the worm 57c.
A shaft base frame 65 having a rack tooth 65a meshing with the pinion 57d and a long guide hole 65b formed in the vertical direction is fixed to a base end portion of the support shaft 55, and a guide protruding from the molding member 61b. The shaft 63d is loosely fitted in the guide hole 65b, the support shaft 55 is inserted through a long hole 63e formed in the molding member 61b so as to move up and down, and the support shaft 55 is formed in the case 52. The large-diameter hole 52d passes through the rear surface of the alignment mechanism 45.

  Therefore, when the left / right moving dial 56 is rotated, the pinion 56e is rotated to move the left / right moving assembly 63 to the left / right to move the support shaft 55 left / right. On the other hand, when the up / down moving dial 57 is rotated, the pinion 57d is rotated. Since the base frame 65 is moved up and down, the support shaft 55 is moved up and down.

  In order to inspect and confirm whether a large number of game nails 14 fixed on the game board 10 are not deviated from their normal positions, first, as shown in FIGS. The hook-like pieces 43 a and 43 b formed on one side edge are loosely fitted into the loose fitting holes 22 a and 22 b of the game board 10, and the support shaft 55 is fitted into the positioning hole 24. At this time, since the holding frame 42 is supported so as to be finely movable up and down and left and right with respect to the game board 10, the holding frame 42 can be moved in any direction as necessary to move to the positioning hole 24. The support shaft 55 can be fitted. Further, the loose clip 25 can be rotated and brought into sliding contact with the surface of the plate-like stopper piece 51 to support the holding frame 42 so as to be finely movable.

Next, the left and right moving dial 56 and the up and down moving dial 57 are rotated to slightly move the support shaft 55 left and right and up and down. At this time, since the support shaft 55 is fitted in the positioning hole 24, the holding frame 42 and the transparent plate 40 integral with the holding frame actually move slightly left and right and up and down. Further, the holding frame 42 can be slightly tilted left and right by moving the holding frame 42 right and left directly by hand with the support shaft 55 as a fulcrum. By performing such fine adjustment, the reference marks 93a and 93b are completely aligned with the reference marks 28a and 28b displayed on the game board 10 in front view. Then, when they match, the knob 48b of the lock piece 48 inserted through the engagement hole 27 is rotated, and the engagement portion 48c is moved to the back side of the game board 10 as shown in FIGS. Engage with the surface. At this time, when the knob portion 48b rides on the wedge portion 49, the shaft portion 48a is pulled forward, so that the holding frame 42 can be firmly fixed to the game board 10.
In this state, the game board 10 is viewed from the front, and it is inspected / confirmed whether the nail head of each game nail 14 matches the nail position mark 92. At that time, a digital microscope, a microscope, or the like may be applied to the surface of the transparent plate 40 to detect a deviation between the nail head of the game nail 14 and the nail position mark 92. For example, as shown as “OK” in FIG. 17, if the nail position mark 92 is positioned within the range of the nail head circle of the game nail 14, the nail position is determined as “NG”. If the mark 92 is located outside the range of the nail head circle of the game nail 14, it will be rejected. In this way, by displaying the nail position mark 92 as a circle having a smaller diameter than the nail head circle, it is easy to determine whether or not it is acceptable in consideration of a certain allowable measurement error.

On the other hand, another embodiment of the alignment mechanism 45 is shown in FIGS. In this embodiment, parts that fulfill the same functions as those of the above embodiment are given the same reference numerals as those in FIGS. In this embodiment, a left-right movement dial 56 for finely moving the support shaft 55 to the left and right is axially supported, and a vertical movement dial 57 for finely moving the support shaft 55 up and down is supported horizontally. . That is, in this embodiment, screw grooves are formed in the outer periphery of the dial shaft 56b of the left and right moving dial 56 and the outer periphery of the dial shaft 57b of the vertical moving dial 57, respectively, and the vertical moving body 70 formed in a box shape is vertically By inserting a shaft 71, the vertical moving body 70 is supported so as to be movable up and down along the vertical axis 71, and a dial shaft 57 b is screwed to the vertical moving body 70 and a horizontal shaft 73 is connected to the left and right moving body 72. The left and right moving body 72 is supported in the up and down moving body 70 so as to be movable left and right along the horizontal axis 73, and the dial shaft 56 b is screwed to the left and right moving body 72. Then, a support shaft 55 is provided on the back surface of the left and right moving body 72 so that the support shaft 55 protrudes from 52d. Therefore, when the vertical movement dial 57 is rotated, the support shaft 55 moves up and down as the vertical movement body 70 moves up and down. When the left and right movement dial 56 is operated, the support shaft 55 moves left and right as the left and right movement body 72 moves left and right. .
Thus, this embodiment can simplify the configuration by eliminating the orthogonal transmission mechanism composed of the worm and the worm wheel in the embodiment shown in FIGS. Then, by rotating the left / right moving dial 56 and the up / down moving dial 57, the transparent plate 40 is finely moved in the same manner as in the above-described embodiment, and the reference marks 28a, 28b and the reference marks 93a, 93b can be brought into a coincident position.

The transparent plate 40 may be fixed to the front surface of the game board 10 when the state of each game nail 14 is inspected / confirmed as described above. When the state is fixed to the front surface of the game board 10, the transparent plate 40 can function as an inner transparent plate of the double transparent plates of the conventional pachinko gaming machine. In that case, as shown in FIG. 23, the transparent plate can be doubled by disposing the transparent plate 75 outside the transparent plate 40. In such a case, the nail position mark 92 will be visible to the player who is playing the game, so that the nail position mark 92 should be similar to the color of the nail head of the game nail 14 in order to make it difficult to stand out.
Further, the nail position display sheet 90 may not be attached to the transparent plate in advance, and may be attached when performing inspection / confirmation work. In that case, after attaching the nail position display sheet 90, the alignment mechanism is operated to align the reference marks 28a and 28b with the reference marks 93a and 93b, and then the inspection / confirmation work is performed. .
Further, the nail position display sheet 90 on which the nail position mark 92 is printed may be attached to the rear side surface of the transparent plate 40 as shown in FIG. Even in such a case, since the nail head of the game nail 14 is opposed to the nail position mark 92, there is little possibility that the game ball will come into contact with the nail position mark 92 during the game. There is almost no risk of wearing out and disappearing. Further, as shown in FIG. 25, the nail position mark 92 printed on the nail position display sheet 90 can be stuck so as to contact the rear side surface of the transparent plate 40. Care must be taken because bubbles may be formed depending on the thickness. In this regard, as shown in FIG. 16 or FIG. 23, there is no such concern by sticking the nail position display sheet 90 to the front surface of the transparent plate 40 so that the printing surface is the front side.
In the embodiment, as shown in FIG. 1, the double transparent plates of the pachinko gaming machine are separated one by one, and the inner transparent plate of them is described as being adjustable in position. The structure may be a multilayer transparent plate in which heavy transparent plates are integrated. Further, in the case of such a multilayer transparent plate structure, it is possible to cope with the model change by attaching the nail position display sheet 90 to the rear surface side of the transparent plate 40 using a peelable adhesive. It becomes possible. On the other hand, when taking countermeasures against the nail position display sheet 90, if the nail position display sheet 90 is attached to the front surface of the transparent plate 40 on the inner side of the multi-layer transparent plate, the nail position display sheet 90 may be changed. It is possible to prevent unjust acts.
