Abstract
A sheet feeder is disclosed, which is mounted in a printer for feeding cut printing sheets one by one to a printing position in the printer. The sheet feeder comprises first and second sheet accommodation sections for accommodating respective stacks of printing sheets. First and second feed roller mechanisms are provided for the respective sheet accommodation sections. These roller mechanisms selectively receive a drive torque from a single reversible drive motor via a selective coupling mechanism. The selective coupling mechanism senses the direction of rotation of the drive motor, and selectively couples the drive motor to either one of the first and second roller mechanisms according to the sensed direction of rotation.
