PURPOSE: To reduce a danger of erroneously dropping in a hoistway from an opened door by being capable of seeing the inside of a control board when a slave door is opened and being capable of entering the hoistway when a main door is opened with the control board. CONSTITUTION: A main door 8 is openably/closably provided through a hinge 9 adjacent to a doorway 7. The main door 8 is usually locked by a lock member 10. When the main door 8 is opened, a person can enter hoistway. A control board 11 is provided on a back surface of the main door 8 and a slave door 12 is openably/closably mounted at a position of the main door 8 at which the control board is positioned through a hinge. The slave door 12 is also usually locked by a lock member 14. When the slave door 12 is opened, the inside of the control board 11 can be seen and the main door 8 is not necessary to be opened at this time. The case of opening the main door 8 is only the case of maintaining and inspecting a motor. Therefore, a danger becomes lower. |
