Abstract
A sensor for detecting the entrance of a document into a sheet feeder. The document sensor is attached to the sheet feeder. The document sensor comprises a printed circuit board, a key peg and a rocking lever. The printed circuit board is attached to the sheet feeder. The printed circuit board has a first lead wire and a second lead wire detached form each other. The key peg is also attached to the sheet feeder pinning the rocking lever so that the rocking lever is free to rotate relative to the key peg. A conductive member is attached to the rocking lever so that rotating the rocking lever is able to establish an electrical connection between the first lead wire and the second lead wire through the conductive member.
