Is attached.

  A suction plate 44 made of a magnetic material is attached to the inner surface of the return panel 8 so as to face the magnet catch 40. When the return panel 8 is closed from the open state, the suction plate 44 comes into contact with the magnet 43 of the movable body 42. At the same time, the movable body 42 is pushed into the main body 41, and the movable body 42 and the return panel 8 are held in the pushed position, that is, the closed position of the return panel 8. From this state, when the movable body 42 is manually pushed together with the return panel 8 in the pushing direction again, the movable body 42 projects by a certain distance in the opposite direction of pushing by the elastic force of the spring (not shown), and the momentum of the projection. Thus, the return panel 8 is detached from the magnet 43 and automatically opens.

  A receiving member 45 is attached to the rotating body 21 of the lock mechanism 18 inside the return panel 8 instead of the lock piece. An auxiliary receiving member 46 is provided above the receiving member 45. The auxiliary receiving member 46 is rotatably attached to a bracket 47 attached to the inner surface of the entrance / exit post 3a via a support shaft 48.

Pushing in the direction is regulated. That is, the pressing of the return panel 8 attracted to the magnet 43 of the magnet catch 40 is prevented by the receiving member 46 and the auxiliary receiving member 46.

  At the time of maintenance and inspection, the rotary member 21 of the lock mechanism 18 is operated using a key to rotate the receiving member 45 integrally with the rotary member 21 in the clockwise direction in FIG. When the receiving member 45 is rotated, the operation is transmitted to the auxiliary receiving member 46 via the link lever 50, and the auxiliary receiving member 46 is also rotated integrally with the receiving member 45 in the clockwise direction.

  Since the receiving member 45 and the auxiliary receiving member 46 are rotated in the clockwise direction, the receiving member 45 and the auxiliary receiving member 6 are detached from the return panel 8 and the return panel 8 can be pushed. Push panel 8 slightly in the closing direction.

  By this pushing, the movable body 42 of the magnet catch 40 is once pushed into the main body 41, and elastically protrudes by the biasing force of the spring in the opposite direction of the pushing, and the return panel 8 is moved to the movable body 42 by the protruding force. The magnet 43 is detached and automatically opened.

  After completion of the maintenance inspection work, the return panel 8 is manually turned in the closing direction. By this operation, the return panel 8 comes into contact with the movable body 42 of the magnet catch 40 in the protruding state and is attracted through the magnet 43, and the movable body 42 is pushed into the main body 41 and locked at the pushed position. Thus, the closed state of the return panel 8 is maintained.

  Thereafter, the receiving member 45 is rotated counterclockwise by operating the rotating body 21 of the lock mechanism 18 using a key. When the receiving member 45 is rotated, the operation is transmitted to the auxiliary receiving member 46 via the link lever 50, and the auxiliary receiving member 46 is also rotated integrally with the receiving member 45 in the counterclockwise direction.

  By rotating the receiving member 45 and the auxiliary receiving member 46 counterclockwise, the receiving member 45 and the auxiliary receiving member 46 come into contact with the inner surface of the return panel 8 and the return panel 8 cannot be pushed in. That is, the operation of pushing the movable body 42 of the magnet catch 40 to separate the return panel 8 and the movable body 42 becomes impossible, and the return panel 8 can be stably locked in the closed state.

  In each of the embodiments, the keyhole on the end face of the key cylinder 20 in the lock mechanism 18 is exposed on the side surface of the entrance / exit post 3a. However, as shown in FIG. 9 as the fifth embodiment, the keyhole is exposed to the outside. It is also possible to configure so that it does not.

  That is, in this embodiment, the end surface of the key cylinder 20 is disposed inside the entrance / exit column 3a, and the opening 55 is formed on the side surface of the entrance / exit column 3a so as to face the end surface. And the mirror 56 is provided in the outer surface of the entrance / exit pillar 3a as a cover member which covers the opening 55. As shown in FIG. The mirror 56 is supported via a hinge 57 attached to the inside of the entrance / exit post 3a. The hinge 57 includes a hinge pin 58 and a hinge piece 59 that rotates around the hinge pin 58, and the hinge piece 59 is joined to the back surface of the mirror 56 through the opening 55.

  Normally, the opening 55 is closed by a mirror 56, and the end face of the key cylinder 20 is covered with the mirror 56. When operating the lock mechanism 18 during maintenance and inspection, the mirror 56 is rotated around the hinge pin 58 to the outer side of the entrance / exit post 3a to open the opening 55, and a key is inserted into the key hole on the end surface of the key cylinder 20 through the opening 55. The lock mechanism 18 is operated by inserting.

  After completion of the maintenance and inspection work, the mirror 56 is rotated in the reverse direction around the hinge pin 58 and closed to the outer surface of the entrance / exit post 3a to cover the opening 55. Thereby, the end surface of the key cylinder 20 is covered with the mirror 56 and is not exposed to the outside, and therefore the design of the outer surface of the entrance / exit post 3a can be improved.
