OPENING AND CLOSING DEVICE

PROBLEM TO BE SOLVED: To prevent doors from being collided with fixed objects by properly determining deceleration start positions when the moving times of the doors are set. SOLUTION: When the doors 2a, 2b are moved from closed positions to open positions, the doors 2a, 2b are decelerated from deceleration positions on the closed position side of the open side, and moved to the open positions. The moving times of the doors 2a, 2b from the open positions to the closed positions are counted with the timer 20 of a CPU 10. When the moving time counted is shorter than a reference time, the CPU 10 moves the deceleration positions to the open positions. COPYRIGHT: (C)2008,JPO&INPIT
