The hole 120 is extrapolated, the lower bent piece 118 is supported on the lower pedestal 104 via the pin 106, and the dish unit 40 is held by the lower pedestal 104. Then, in this state, the dish unit 40 is moved substantially horizontally so that the inlet side of the notch 140 of the upper bent piece 116 faces the pin 112 of the upper base 108 and the notch 140 is fitted from the circumferential direction of the pin 112. Let

  In a state where the upper bent piece 116 is not in contact with the pin 112, the lock member 130 is disposed at the position shown in FIG. 9A and closes the notch 140, but FIG. As shown, when the pan unit 40 is horizontally moved in a direction in which the pin 112 is pressed by the lock portion 132, the lock portion 132 moves toward the direction in which the urging force of the torsion spring 126 resists around the shaft 124 (direction of arrow B). ) Rotate to open the notch 140.

  For this reason, the notch 140 can be moved to the back via the pin 112. At this time, the lock part 132 is maintained in a state where the notch part 140 is opened by the pin 112. 9C, when the end edge portion 140A of the notch portion 140 is brought into contact with the pin 112, the tip end portion of the lock portion 132 passes through the pin 112, and the lock portion 132 causes the shaft 124 to move. By rotating in the direction of the arrow A about the center, the notch 140 is closed, and the pin 112 is rotatably supported by the notch 140 and the lock 132. At this time, the unlocking piece 135 abuts against the edge of the opening 138 and is restricted from moving.

  In this manner, with the dish unit 40 held by the lower pedestal 104, the notch 140 is moved via the pin 112 by simply moving the dish unit 40 substantially horizontally with respect to the inner frame 14, and the pin 112 can be rotatably supported by the notch 140 and the lock pieces 132A and 132B. That is, when the upper center of rotation of the dish unit 40 is supported by the inner frame 14, the dish unit 40 is held by the lower base 104, and there is no need to lift the dish unit 40. The burden on is reduced.

  In this embodiment, the unlocking piece 135 is exposed from the back side of the dish unit 40. Accordingly, when the unlocking piece 135 is rotated in the arrow B direction with the dish unit 40 opened, the notch 140 can be opened. Therefore, the upper bent piece 116 can be removed from the pin 112 by moving the notch 140 from the end edge 140A to the opening side via the pin 112, and the dish unit 40 is removed from the inner frame 14. Can do.

  Further, in this embodiment, the upper bent piece 116 and the lower bent piece 118 are formed at both ends of the hinge member 114, the shaft hole 120 through which the pin 106 can be inserted is provided in the lower bent piece 118, and the upper bent piece 116 is pinned. A notch portion 140 capable of pivoting 112 is provided. For this reason, compared with the case where the upper bent piece 116 and the lower bent piece 118 are provided separately, the center of curvature of the shaft hole 120 and the end edge of the notch 140 can be made to coincide in plan view. The position accuracy at the rotation center of the dish unit 40 can be improved.

  By the way, in this embodiment, as shown in FIG. 10, the unlocking piece 135 is exposed from the back side of the dish unit 40, and the dish unit 40 is closed by the inner frame 14 and locked by the locking device 68. As shown in FIGS. 8 and 10, a passage that leads from the gap between the dish unit 40 and the inner frame 14 to the inside of the inner frame 14 is blocked by a lock release piece 135.

  As a result, as shown in FIG. 11, even if the unauthorized tool P enters from the gap between the dish unit 40 and the inner frame 14, the tip of the unauthorized tool P hits the unlocking piece 135 and its movement is restricted. Therefore, it is possible to prevent the unauthorized tool P from entering the inner frame 14.

  A wall piece 108A is suspended from the end of the upper pedestal 108 and fixed to the upper left side of the launching device 60 provided on the inner frame 14, but the distal end surface of the unlocking piece 135 is attached to the wall piece 108A. The gap between the unlocking piece 135 and the wall piece 108A is eliminated by contact or proximity.

  Since the wall piece 108A is disposed in a passage that leads from the gap between the dish unit 40 and the inner frame 12 to the inside of the inner frame 14, the wall piece 108A and the unlocking piece 135 face each other, By eliminating the gap between the wall pieces 108A, the unauthorized tool P can be prevented from entering the inner frame 14.

  Here, the shape of the unlocking piece 135 is a flat plate, but it is only necessary to block the passage leading to the inside of the inner frame 14 from the gap between the dish unit 40 and the inner frame 12, so that the unlocking piece 135 is made as much as possible. It is better to provide a wide space. Further, the shape of the unlocking piece 135 is not limited to this.

  For example, although not shown, a standing wall standing on the upper surface of the unlocking piece 135 may be provided at the side end of the unlocking piece 135 in a portion exposed from the back side of the dish unit 40. Thereby, even if the unauthorized tool P contacts the upper surface of the unlocking piece 135 and then moves along the upper surface of the unlocking piece 135, the movement of the unauthorized tool P can be restricted by the standing wall. Further, the upper surface of the unlocking piece 135 may be roughened to restrict the movement of the tip of the unauthorized tool P.

  In addition, this embodiment is merely an example, and it is needless to say that the embodiment can be appropriately changed without departing from the gist of the present invention.
