The control portion 4 controls the direction, angle and speed of rotation of a motor 7 and the opening and closing movement of a door 1 is controlled via a belt 8. During the closing motion of the door 1 the counting portion 2 actuates a mat switch 9 and inputs counted numbers one by one to the control portion 4. Door opening corresponding to a predetermined number of inversions is set and stored in the storage portion 3. The counting portion 20 inputs the number of pulses to the control portion 4 and the storage portion 21 inputs the number of pulses to the control portion 4 and then the door is stopped open. Thereby door opening can be economically and properly obtained. |
