  On the lower surface of the inner wall of the outer frame 11, a left lower corner portion from the front is provided with a fourth lower shaft 11a (see FIG. 11) protruding upward, and on the lower surface of the main body base 12, A fourth lower shaft attachment hole 12e (see FIG. 11) is formed at the left corner from the front. When the main body base 12 is attached to the outer frame 11, the fourth lower shaft 11a is inserted into the fourth lower shaft attachment hole 12e. As a result, the fourth upper shaft 16a is held in the fourth upper bearing 15, and the fourth lower shaft 11a is held in the fourth lower shaft mounting hole 12e so that it can be inserted and removed. Thus, the main body base 12 is pivotally attached to the outer frame 11 so as to be detachable and rotatable by the fourth upper shaft 16a and the fourth lower shaft 11a.

  As shown in FIG. 11, an insertion portion 16b is formed at the upper end of the fourth upper shaft 16a. The insertion portion 16b is cylindrical and has a hemispherical tip. The insertion portion 16 b is inserted into the receiving portion 48 a of the bearing member 48 attached to the fourth upper bearing 15.

  A positioning portion 16c is formed at the lower end of the fourth upper shaft 16a. The positioning portion 16c is formed in a cylindrical shape that is slightly thinner than the insertion portion 16b. Further, a disc-shaped flange 16d is provided at a portion that becomes a boundary between the insertion portion 16b and the positioning portion 16c of the fourth upper shaft 16a. The fourth upper shaft 16 a is attached to the second upper bearing 16 by being inserted so that the positioning portion 16 c penetrates the hole 55 a formed in the base member 55 of the second upper bearing 16. When the positioning portion 16 c is attached, the flange 16 d comes into contact with the upper surface 16 e of the second upper bearing 16, and the positioning portion 16 c protrudes to the lower surface side of the base member 55. The base member 55 has the same configuration as the base member 47 except for a portion where a hole 55a through which the positioning portion 16c is inserted is formed.

  A bearing member 56 is attached to the lower surface of the base member 55. The bearing member 56 is formed with a receiving portion 56 a formed in the same shape as the receiving portion 48 a of the bearing member 48. On the wall surface surrounding the receiving portion 56a, a plate-like locking portion 56b protruding inward is formed. The bearing member 56 is attached to the base member 55 by locking the locking portion 56b so that the positioning portion 16c is nipped by the locking portion 56b, positioning the bearing member 56, and then positioning the locking portion 56b. The caulking process is preferably performed by an appropriate method such as heat welding. Thus, when the fourth upper shaft 16a is held by the fourth upper bearing 15 and the second upper shaft 35 is held by the bearing member 56 of the second upper bearing 16, the fourth upper shaft 16a and the second upper shaft 35 are retained. And an axial center (axial center part) are arranged on the same axis.

  The second upper shaft 35 is formed with an insertion portion 35c having the same configuration as the insertion portion 16b of the fourth upper shaft 16a. The receiving portion 56a of the bearing member 56 has an axial direction of the second upper shaft 35. When the support member 30 is moved toward the main body base 12 in the orthogonal direction (the direction of the arrow X shown in FIG. 6), the insertion portion 35c is inserted. The insertion port 56 b of the bearing member 56 has the same configuration as the insertion port 48 b of the bearing member 48, and the side wall surface 56 d of the bearing member 56 has the same configuration as the side wall surface 48 d of the bearing member 48. Thus, since parts other than the locking part 56b in the bearing member 56 have the same configuration as the bearing member 48, detailed description will be omitted.

  The third upper bearing 34 includes a base member 57 having the same configuration as the base member 55. On the lower surface side of the base member 57, there are members (bearing member 56, lock member 49, torsion spring 50, support shaft 51, washer 53, etc.) for holding the third upper shaft 40 in the same manner as the second upper bearing 16. It is attached.

  The second upper shaft 35 includes an insertion portion 35c, a positioning portion 35d, and a flange 35e having the same shape and the same configuration as the fourth upper shaft 16a, and is attached to the base member 57 in the same manner as the fourth upper shaft 16a. Similarly to the bearing member 56, the second upper shaft 35 is attached to the base member 57 by locking the locking portion 56b with the positioning portion 35d and positioning the locking portion 56b. The caulking process is preferably performed by an appropriate method such as heat welding. Accordingly, when the second upper shaft 35 is held by the second upper bearing 16 and the third upper shaft 40 is held by the bearing member 56 of the third upper bearing 34, the second upper shaft 35 and the third upper shaft 40 are retained. And an axial center (axial center part) are arranged on the same axis. In the receiving portion 56a of the bearing member 56 provided on the base member 57, the window portion 31 is moved toward the support member 30 in a direction orthogonal to the axial direction of the third upper shaft 40 (in the direction of the arrow X shown in FIG. 6). When this is done, the tip of the third upper shaft 40 is inserted.

  Further, a second lower shaft 37 protruding downward is formed on the lower surface of the lower end portion of the support portion 32 of the support member 30, and the second lower shaft 37 is formed on the lower surface of the inner wall of the portion of the main body base 12 where the support member 30 is accommodated. A lower shaft attachment hole (second bearing) 12f is formed. When the support member 30 is attached to the main body base 12, the second lower shaft 37 is inserted into the second lower shaft attachment hole 12f. As a result, the second upper shaft 35 is held in the second upper bearing 16 and the second lower shaft 37 is detachably inserted into the second lower shaft attachment hole 12f, and is rotatably held. As described above, the support member 30 is pivotally supported by the main body base 12 so as to be detachable and rotatable by the second upper shaft 35 and the second lower shaft 37.

  When attaching the window 31 to the support member 30, the third upper shaft 40 is held by a bearing member 56 provided on the third upper bearing 34. In addition, a third lower shaft attachment hole (third bearing) 31c is formed in a left corner (one side portion) from the front surface of the lower surface of the window portion 31. When the window portion 31 is attached to the support member 30, the third lower shaft 36 is inserted into the third lower shaft attachment hole 31c. As a result, the third upper shaft 40 is held in the third upper shaft bearing 34 and the third lower shaft 36 is inserted into and removed from the third lower shaft mounting hole 31c and is rotatably held. As described above, the window 31 is detachably and pivotally supported on the support member 30 by the third upper shaft 40 and the third lower shaft 36.

  As a result, when the pachinko machine 10 is assembled, the axis of the second upper shaft 35, the third upper shaft 40, the fourth upper shaft 16a, the second lower shaft 37, the third lower shaft 36, and the fourth lower shaft 11a. Are arranged so that they are the same in the axial direction.

  Next, the operation of the pachinko machine 10 configured as described above will be described. For example, in order to remove the glass frame unit 14 from the main body base 12 when performing maintenance work such as replacement of model, breakage or failure, first, the glass frame unit 14 is fixed in a state of penetrating through the upper and lower insertion holes 13b and 33a. The upper and lower first and second fixing members 45 and 60 are set by moving from the fixing position to the detaching position so that they cannot be detached from the insertion holes 13b and 33a. The rotation impossible state of 30 is released, and the end of the game board 13 opposite to the shaft side is rotated from the main body base 12 (state shown in FIG. 5). Then, the third fixing member 46 is inserted through the insertion hole 13 c by closing the window 31 with respect to the game board 13. The third fixing member 46 is set from the removal position to the fixed position so that it cannot be detached from the insertion hole 13c, and the game board 13 and the window 31 are fixed and integrated. Thereafter, the glass frame unit 14 in which the support member 30 in a state of supporting the game board 13 and the window 31 is integrated is lifted upward, and the second lower shaft 37 is pulled out from the second lower shaft mounting hole 12f.

  The glass frame unit 14 may be lifted by the second upper shaft 35 coming into contact with the base member 55 of the second upper bearing 16 or the upper surface of the support member 30 coming into contact with the lower surface of the bearing member 56. The glass frame unit 14 is lifted between the second upper shaft 35 and the base member 55 and between the upper surface of the support member 30 and the lower surface of the bearing member 56 to prevent the second lower shaft 37 from moving. 2 The distance that can be pulled out from the lower shaft attachment hole 12f is set.

  After the second lower shaft 37 is pulled out, the second upper shaft 35 is provided on the second upper bearing 16 by tilting the glass frame unit 14 forward with the second upper shaft 35 as a fulcrum and moving it downward. The bearing member 56 is pulled out from the receiving portion 56a. Thereby, the removal of the glass frame unit 14 is completed.

  For example, when a new glass frame unit 14 different from the glass frame unit 14 removed at the time of model exchange is attached to the main body base 12, first, the second lower shaft 37 is inserted into the second lower shaft mounting hole 12f. After the insertion of the second lower shaft 37, the glass frame unit 14 is moved in the direction of arrow X shown in FIG.

The window portion 31 can be lifted by the upper surface of the window portion 13 contacting the lower surface of the bearing member 56 or the third upper shaft 40 contacting the base member 57 of the third upper bearing 34. In order not to disappear, the window portion 31 is lifted between the upper surface of the window portion 13 and the lower surface of the bearing member 56 and between the third upper shaft 40 and the base member 57 so that the third lower shaft 36 is moved to the third lower portion. A distance that allows the shaft to be pulled out from the shaft attachment hole 31c is provided.

  When the window portion 31 is attached to the support member 30 that does not support the game board 13, first, the upper portion of the window portion 31 is inserted such that the third lower shaft 36 is inserted into the third lower shaft attachment hole 31 c.

Then, in a state where the third lower shaft 36 is inserted into the third lower shaft mounting hole 31c, the window portion in the arrow X direction shown in FIG. 6 is tilted so that the upper portion of the window portion 31 is inclined to the rear side with the insertion portion as an axis. 31 is moved, and the third upper shaft 40 is inserted into the receiving portion 56a of the bearing member 56 provided in the third upper bearing 34 as shown in FIGS. To do. Thereby, the attachment to the support member 30 of the window part 31 is completed. Further, when the game board 13 is attached to the support member, the first upper shaft of the game board is inserted into the first upper bearing of the support member, and the first lower shaft of the game board is inserted into the first lower bearing of the support member. This completes the attachment of the game board to the support member.

  In order to remove the main body base 12 from the outer frame 11, the main body base 12 is lifted upward so that the fourth lower shaft attachment hole 12e is pulled out from the fourth lower shaft 11a. After the fourth lower shaft mounting hole 12e is pulled out from the fourth lower shaft 11a, the main body base portion 12 is pushed downward while the lower portion of the main body base portion 12 is tilted to the front side, and the fourth upper shaft 16a is moved to the fourth upper bearing. 15 is pulled out from the receiving portion 48a of the bearing member 48 provided in the shaft 15. Thereby, the removal of the main body base 12 from the outer frame 11 is completed. The fourth upper shaft 16a and the base member 47 are arranged so that the fourth upper shaft 16a does not come into contact with the base member 47 of the fourth upper bearing 15 and cannot lift the main body base 12. A distance is provided between the body base 12 and the fourth lower shaft attachment hole 12e so that the fourth lower shaft attachment hole 12e can be pulled out from the fourth lower shaft 11a.
