A sheet pick-up device of an automatic document feeder is provided. The sheet pick-up device includes a two-way clutch transmission mechanism, a sheet pick-up arm, a stopper and a linking assembly. When the two-way clutch transmission mechanism is operated to have the sheet pick-up arm move to a standby position, the stopper is moved with the linking assembly to be in a stopping position. Whereas, when the two-way clutch transmission mechanism is operated to have the sheet pick-up arm move to a sheet pick-up position, the stopper is in a non-stopping position. The sheet pick-up device has enhanced operating stability. |
