  • Patent number: 4982235
    Abstract: The invention comprises an image scan apparatus wherein a simple document feed unit is provided for feeding a document to be scanned to a predetermined position on a glass platen. The document feed unit is mechanically coupled to an image sense unit which is reciprocally moved between a home position and a scan start position. The document feed unit includes a frictional roller which is in contact with the glass platen. A leading edge of the document is inserted by an operator at a home position between a frictional roller and the glass platen. The frictional roller is mounted on a shaft via a one-way clutch or one-way bearing. The one-way clutch inhibits the rotation of the frictional roller during its movement from the home position to a scan start position. The leading portion of the document is engaged by the frictional roller, and the document is fed to a predetermined position on the glass platen as the frictional roller and the image sense unit are moved to the scan start position.
