<P>PROBLEM TO BE SOLVED: To control height of an opening/closing member accurately. <P>SOLUTION: An MPU 1 acquires the number of pulses of an electrically-driven motor 31 corresponding to a plurality of sections formed by dividing a blind part uniformly between the upper and lower parts thereof, the number of pulses corresponding to a designation position of a user in a space between the upper and lower parts of the blind, and then a difference between the number of pulses corresponding to a prescribed position in the space between the upper and lower parts of the blind and the number of pulses corresponding to a designation position. The MPU 1 re-acquires the number of pulses corresponding to the sections such that lifting amount of the blind part becomes uniform according to a primary function, on the basis of a rotation amount preliminarily calculated corresponding to the sections, the acquired difference, and a ratio of the length between the designation position and an upper limit position to the length between the designation position and a lower limit position. When the MPU 1 receives an operation command in operation, the MPU 1 counts the number of pulses which is the number of pulses of the electrically-driven motor 31 to be detected, and operates the electrically-driven motor 31 to rotate until instructing the number of pulses corresponding to the reacquired designation sections. <P>COPYRIGHT: (C)2013,JPO&INPIT |
