PROBLEM TO BE SOLVED: To provide a control device of an electrically-driven horizontal blind which improves the accuracy of an angle adjustment operation of a slat, and can prevent the damage of a motor drive circuit or the like caused by a lift operation of the slat, in the electrically-driven horizontal blind which performs the lift operation and the angle adjustment operation of the slat by using one motor.SOLUTION: An electrically-driven horizontal blind comprises: a drive shaft which is rotationally driven by one DC motor; a slat drive unit which lifts a slat, or angle-adjusts the slat on the basis of the rotation of the drive shaft; a motor control part which controls an operation of the motor; and detection means which detects a lift height and a rotational angle of the slat on the basis of the rotation of the drive shaft. The motor control part comprises first control parts 19, 21 which control the DC motor 9 at a lift operation of the slat at a DC voltage, and second control parts 20, 21 which PWM-control the DC motor 9 at an angle adjustment operation of the slat.SELECTED DRAWING: Figure 2 |
