Abstract:
A blind apparatus comprising a drum on which a blind is wound, a motor for rotating the drum in a blind spreading direction or a blind take-up direction in order to expand or take up the blind, an extrusion mechanism having a foldable arm for thrusting the leading end of the blind by a spring force in the blind spreading direction, and a one-way clutch for transmitting the rotating force of the motor to the drum when the drum rotates in the blind take-up direction, further comprising:a stopper for regulating arm position by stopping movement of the arm near the blind spreading end position, and a detecting circuit for detecting a motor lock current when taking up the blind, wherein a stopping position in the blind spreading direction is defined by the arm position regulation by the stopper, and a stopping position in the blind take-up direction is detected by the motor lock current by the detecting circuit.
