- the outer cylinder 23 can be rotationally displaced between a first position (normal position) shown in FIG. 8 and a second position (maintenance position) shown in FIGS. 9 and 10.
- the outer cylinder 23 is also displaced in the first position force to the second position as the inner cylinder 22 is rotated by the unlocking operation using the unlock key. Further, when the outer cylinder 23 is displaced to the second position, it is positioned (latched) in the second position until it is returned to the first position by manual operation of the landing or hoistway internal force. 23 is provided with a mark 23a indicating the rotational position of the outer cylinder 23.
- the control panel 14 sets the operation mode to the normal mode when the outer cylinder 23 is located at the first position, and sets the operation mode to the maintenance mode when the outer cylinder 23 is located at the second position.
- FIG. 11 is a flowchart showing the operation of the control panel 14 of the second embodiment when the car is started.
- the operation mode is set to the normal mode and automatic operation is permitted (step S6). If the outer cylinder 23 is not in the first position, the operation mode is set to the maintenance mode, automatic operation is disabled, and only manual operation is permitted.
- the outer cylinder 23 when the unlocking operation is performed on the locking apparatus using the unlocking key, the outer cylinder 23 is displaced to the first position force second position and to the second position. The outer cylinder 23 remains in the second position until it is manually returned to the first position.
- the control panel 14 sets the operation mode to the normal mode when the outer cylinder 23 is located at the first position, and sets the operation mode to the maintenance mode when the outer cylinder 23 is located at the second position. For this reason, the car is automatically operated with maintenance personnel in the hoistway. It can prevent more reliably.
- display means for displaying that the outer cylinder 23 is not in the first position and is operating in the maintenance mode may be provided on the hall operation panel on each floor. As a result, it is possible to prevent a general user from trying to operate the hall operation panel or waiting for a force even though the operation is in the maintenance mode.
- the locking device is unlocked by rotating the inner cylinder 22, but, for example, the locking device is lifted by lifting the tip of the unlocking key as in the first embodiment. It is good also as a structure which unlocks.
- the movable member may be moved up to the second position by the unlocking operation of the unlocking key and latched at the first position until it is moved down by the manual operation.
- the unlocking operation method is not particularly limited, and the displacement direction of the movable member is also changed according to the unlocking operation method.
- the present invention can also be applied to a type that is not exposed (a concealment type). For example, even if the unlocking operation is performed by inserting an unlocking key into the gap between the landing door and the landing three-way frame, the unlocking operation displaces the first position force to the second position. By using the movable member, the same effect as in the second embodiment can be obtained.
