DOOR OPENING/CLOSING DEVICE

摘要

PROBLEM TO BE SOLVED: To allow a door to be quickly opened and closed even with a weak operating force applied to the door.

SOLUTION: A door opening/closing device comprises: a door 10; a door knob 11 for opening/closing the door 10; a touch sensor 12 (operation detection sensor) that detects that the door knob 11 is gripped by an operator for opening/closing, and keeps outputting a detection signal while the door knob 11 is being gripped; a motor 13 (driving means) that applies a driving force in opening/closing directions to the door 10; and control means 14 that outputs a control signal for accelerating the opening/closing speed of the door 10 to the motor 13 on condition that the detection signal is output from the touch sensor 12.
