ABSTRACT:
An opening-and-closing control device is disclosed, in which speed of an opening-and-closing body can be increased even while automatic operation is performed. The device includes an operation knob that performs opening-and-closing control of an opening-and-closing body according to an instruction from an operation switch which is switchable to each of positions of “automatic closing”, “manual closing”, “neutral”, “manual opening” and “automatic opening”, wherein first the operation knob is operated to start the automatic opening operation, and then when the operation knob is held in the position of the “automatic opening”, an opening speed of the opening-and-closing body is increased according to a time period for which the operation knob is held in the position of the “automatic opening”, therefore the opening-and-closing body can be opened at high speed even while the automatic opening operation is performed.
