Automatic operation device for e.g. door during renovation of building, has detection unit detecting radio frequency identification tag to produce activation signal when detection unit detects tag

摘要

The device has an electric pump (7) for displacing a tooted bar (4) and a toothed axle (5) in an opening direction, and a spring (8) for displacing the bar and a toothed wheel in a closing direction opposite to the opening direction. A control unit (11) activates the electric pump when the control unit receives an activation signal and activates the spring for preset time after activation of the electric pump. A detection unit (12) detects a radio frequency identification tag to produce the activation signal when the detection unit detects the tag.
