PURPOSE: An electric blind device is provided to smoothly operate by avoiding the need of laying a switch on the wall, providing a user with an easy operation, and preventing the separation of an operating rope. CONSTITUTION: An electric blind device comprises a head box (1100), a rotary drum, an operating rope (1300), a separation preventing unit, a switching unit (1400), a driving rope (1500), and a motor. The head box is extended in a longitudinal direction of a blind. The rotary drum is placed inside the head box and manipulates the operating rope. The operating rope is wound along the outer periphery of the rotary drum and operates the blind. The separation preventing unit is mounted on the head box and prevents the separation of the operating rope from the rotary drum. The switching unit is placed inside the head box and supplies power to the motor or blocks the power. The driving rope is combined to both ends of a casing of the switching unit and is exposed to the outside of the head box. The motor is placed inside the head box and rotates the rotary drum. |
