2141311 9403968 PCTABS00030 During a blanking period from the actuation of the motor driving to a given time T, the motor current is not compared with its threshold value. During the latter stage Tm of the blanking period, a catching of anything in the window is detected on the basis of the value of the motor current, and after the blanking period, it is detected on the basis of the variation of the motor current, thus preventing any misoperation due to noise in the initial period of the motor driving, and reliably detecting a catching of anything in the window.
