PROBLEM TO BE SOLVED: To shorten the time when a door is maintained in the opened state while attaining semi-automatic opening/closing operation of the door. SOLUTION: An operation instruction operator 11 activates a semi-automatic opening timer 21 when it receives semi-automatic opening instruction P10 outputted from a door opening/closing action switch 6a or a door opening action switch 6b, and the operator 11 calculates a speed instruction value P4 so as to automatically close the door 1 and outputs it to a speed controller 13 when the semi-automatic opening timer 21 is timed-up. Thereby, the door 1 performed with the opening action in the semi-automatic state is automatically closed after passing of the setting time. COPYRIGHT: (C)2009,JPO&INPIT
