The bearing 71 is formed by bending one end of a thin plate-shaped steel material, and has a substantially U-shaped cross section. Further, the steel plate portion is fitted into a notch step portion 17a formed on the top surface of the top plate 17 and attached by screws or the like, and the bearing 71 is located in the notch 17b formed on the front end portion of the top plate 17. At this time, the front end of the bearing 71 does not protrude in the front direction from the front end of the top plate 17.
[0047]
  (Support shaft support 80)
  As shown in FIG. 3, the support shaft support 80 is a shaft 81 fixed to a support piece that rises from the upper surface on the front side of the support 21 of the replacement unit 2. The shaft 81 has an outer diameter that fits the inner diameter of the bearing 71 of the housing shaft support portion 70. The shaft 81 can be hooked on the bearing 71 from above, and the exchange unit 2 can be rotated while being hooked on the bearing 71. Is formed.
[0048]
  As shown in FIG. 6, when the shaft 81 is hooked on the bearing 71 and the replacement unit 2 is stored in the housing unit 1, the center of gravity O of the replacement unit 2 (the rotation shaft of the rotary reel 23) is It is located in the place which shifted | deviated to the front side rather than the center position. By forming in this way, a force in the back direction of the housing unit 1 is always applied to the replacement unit 2. Therefore, when storing the replacement unit 2, the operator does not require much force to insert the replacement unit 2 to the back of the housing.
[0049]
  (Anti-fraud plate 90)
  The fraud prevention plate 90 is attached to the shaft support 8 after the shaft 81 is hooked on the bearing 71 and the exchange unit 2 is accommodated in the housing unit 1. That is, as shown in FIGS. 3 and 4, the fraud prevention plate 90 is a thin plate-like cover member having an upright surface 92 and a barb 93, and when the upper surface 91 is fitted into the notch step portion 17 a of the top plate 17, The upper surface 91 is formed so as to cover the shaft support 8 from the plane side, and the upright surface 92 covers the shaft support 8 from the front. And as shown in FIG. 4, when the upper door 30 is closed, the upright surface 92 and the return 93 will be hidden in a housing | casing.
[0050]
  Further, as shown in FIGS. 3 and 5, the fraud prevention plate 90 has a screw hole in the vertical surface 92 and is fixed to the front end surface of the top plate 17 with a screw. Therefore, when the upper door 30 is closed, the fixed portion cannot be touched from the outside. Furthermore, since the upper surface 91 is fitted in the notch step portion 17a and is flush with the upper surface of the top plate 17, it is difficult to peel it off. Further, since the return 93 is provided, it is difficult to reach the inside even if a rod-like entering object is inserted from the gap between the upper door 30 and the top surface of the top plate 17.

  (Replacement of exchange unit 2)
  Next, the attachment / detachment of the replacement unit 2 in the separation type slot machine S having the above-described configuration will be described.
  First, when taking out the replacement unit 2, the lower door 40 is unlocked to unlock the upper door 30, and the upper door 30 is opened to remove the tamper-proof plate 90. Then, after releasing the fixing device 10, the replacement unit 2 is pulled out to the front side. Then, as shown in FIG. 7, the replacement unit 2 rotates to the front side around the shaft support portion 8. At this time, the shaft 81 and the bearing 71 have little frictional resistance due to contact between the circumferential surfaces, and the guide rail 19 provided on the side plate 16 is supported by the exchange unit 2 suspended from the shaft support 8. Since the movement is performed while supporting the 21 guide rollers 22 from below, a large force is not required to rotate them. When the guide roller 22 is disengaged from the guide rail 19, if the replacement unit 2 is lifted upward, the shaft 81 and the bearing 71 are disengaged and the replacement unit 2 can be removed.
[0052]
  In this way, the replacement unit 2 can be pivoted about the pivotal support 8 and pulled out and then lifted up. Therefore, compared to the case where the replacement unit 2 is taken out from the back of the housing in the horizontal direction, the operator The burden on is considerably reduced.
  Next, when mounting the replacement unit 2, first, the shaft 81 of the replacement unit 2 is hooked on the bearing 71 with the front door 30 opened. Since the shaft 81 is formed on the front side of the support body 21, the operation of hooking on the bearing 71 can be performed while visually confirming. At this time, the guide roller 22 of the support 21 is fitted into the guide rail 19 provided on the side plate 16. Thereafter, the replacement unit 2 is placed inside the casing while supporting the lower front portion of the replacement unit 2 so that the replacement unit 2 does not rotate with its own weight and vigorously around the shaft support portion 8. At this time, due to the displacement of the center position of the shaft support 8 and the center of gravity of the replacement unit 2, the replacement unit 2 is always applied with a force in the rear of the housing, so the replacement unit 2 is stored in the opening 11. Even if the hand is released and released, the replacement unit 2 moves in the rear direction of the housing and comes into contact with the back plate 18 and stops. Thereafter, the depth position of the replacement unit 2 is finely adjusted, fixed inside the casing by the fixing device 10, and the fraud prevention plate 90 is attached.
[0053]
  As described above, since the replacement unit 2 can be moved to a sufficient depth position only by rotating around the pivotal support portion 8, a predetermined mounting position can be obtained as compared with the case where the replacement unit 2 is pushed in in the horizontal direction. It is possible to eliminate problems caused by insufficient installation that does not reach the maximum.
  Further, since the replacement unit 2 is supported on the guide rail 19 from below via the guide roller 22, the replacement unit 2 is firmly held even during attachment / detachment, so that the work can be reliably performed. Further, by adjusting the frictional resistance between the guide roller 22 and the guide rail 19, it is possible to prevent the replacement unit 2 from rotating vigorously, and buffer the rear plate 18 and the rear end of the guide rail 19. By attaching the member, it is possible to relieve the shock when the replacement unit 2 pivots vigorously and facilitate positioning in the front-rear direction.
