The present invention relates to a screen take-up device characterized in that the output from the normal-reverse turn motor of outer-rotor type contained in a screen take-up shaft is transmitted to the take-up shaft after being reduced in speed; brake is applied by a braking mechanism on the inertia output from the motor in sync with the stopping of the aforementioned motor; the number of revolutions of the take-up shaft is counted by a counter and the motor is controlled to stop at the preset number of revolutions; and the output from the manual shaft which is manually rotated in normal-reverse way is transmitted to the take-up shaft through a self-locking mechanism after being reduced in speed.
