PROBLEM TO BE SOLVED: To provide a sliding door closer device capable of reducing the energizing force of a spring type winder, automatically opening a sliding door to the full while restraining the power consumption, and shifting to the closing operation after keeping the full-open state for designated time. SOLUTION: A sliding door 35 is hung down on sash rollers 33a, 33b running on a rail 32 through brackets 34a, 34b, and the brackets are forcedly closed by a spring type winder 36. The bracket 34a is provided with a D.C. motor 1 having a turning angle sensor 3, a one-way clutch 2 for transmitting only the turning force in the door closing direction between the motor and the axle of the sash roller 33a, and a control part 5, and the sliding door 35 is provided with a touch sensor 4. The control part 5 receives an open command signal from the touch sensor 4, the D.C. motor 1 is started to open the door by power feeding, and when the pulse output is stopped after the lapse of a designated time from starting, a clocking for a designated full-open time is started, and when clocking is ended and an open command signal is not input, power feeding to the D.C. motor 1 is ended. |
