PURPOSE:To ensure the safety of passengers by arranging a door opening or closing switch to be operated by a motorman, a door opening or closing state detecting switch for detecting that doors are closed up to a specified position, and first and second safety devices. CONSTITUTION:When a door opening or closing switch 30 is set in an opening state by the operation of a motorman, then a relay in a first control circuit C127 functions, and via a railway 28, an exciting signal is fed to the solenoid section 22a of a solenoid valve 22, and the solenoid valve 22 is switched to an opening position. After that, by the operation of the motorman, the door opening or closing switch 30 is set in a closing state, and a movable contact 30a is switched to a fixing contact 30c, and a DC power source to the solenoid section 22a of the solenoid valve 22 is interrupted. When passengers are placed between doors, about 10 - 15mm in front of closing a door opening or closing confirming switch 26, then a second detecting switch 38 functions, and the doors are moved to the opening position again. As a result, the safety of the passengers from the doors can be surely ensured. |
