Title: Device for opening and closing body
Inventor: SHIMAMURA YOSHINORI
IPC: E06B9/82
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To enable an opening/closing body to be held stopped during its opening or closing movement and to construct a device easily at low cost. SOLUTION: In an opening/closing body, a rotating direction detecting part 2 detects rotating direction, which is input to a brake control part 4. If the rotation of the opening/closing device is detected while the opening/closing device is stopped, the brake control part 4 supplies a microcurrent to the opening/closing device in the opposite direction to the rotation. Therefore, the opening/closing device is held stopped, and the opening/closing body is held stopped in its stopped position.
