Therefore, it is possible to open and close even if the receiving member and the engagement position of the pin are inside the storage box, and it is unnecessary to project the face plate toward the inside of the car. Further, in order to open and close the face plate 5, the storage box 4 only needs to have a depth necessary for the face plate piece to sink. Therefore, the original depth required to store the operation tool is required. It also has the effect of being sufficient.

An elevator car operating panel according to claim 2 is the elevator car operating panel according to claim 1, wherein:
Only one side of the face plate piece is locked to the storage box by the hinge mechanism. Therefore, since the face plate piece is moved to the side opposite to the side where the hinge mechanism is provided, the face plate piece can be opened even if the side where the hinge mechanism is provided is partitioned by the wall surface. The effect is played together.

An elevator car operating panel according to claim 3 is the elevator car operating panel according to claim 1, wherein:
Both sides of the face plate piece are locked to the storage box by a hinge mechanism, and one end of the elongated hole of the receiving tool is set as an open end, and the engagement position of one receiving tool and the pin inserted into this receiving tool is set to the storage box. The pin of the other hinge mechanism is released from the receiver via the open end when the pin is moved toward the center. For this reason, the face plate piece can be opened from either the left or right side, and it is possible to eliminate the problem caused by the opening.

An elevator car operating panel according to claim 4 is the elevator car operating panel according to claim 1, wherein:
A predetermined face plate piece of the plurality of face plate pieces is locked to the storage box by a hinge mechanism, and a lever is attached to either the predetermined face plate piece or an adjacent face plate piece adjacent to the predetermined face plate piece. , An engaging element is attached to the other, and
The lever is a locked state in which a predetermined face plate piece is locked to an adjacent face plate piece at a normal position. Therefore, the face plate piece is not opened by a general user and the operating tool is not abused, which is also effective.

An elevator car operating panel according to claim 5 is the elevator car operating panel according to claim 1,
A positioning mechanism for stopping the lever at the normal position of the face plate piece is attached to the engaging element. For this reason, the effect that the face plate piece can be stably stopped at the normal position is also obtained.
