ABSTRACT:
A paper detector for a printer of the type having a printer head, a platen and two paper guide paths for guiding recording paper to a position between the printer head and the platen. The paper detector comprises a reflection-type photo sensor comprised of a light-emitting element and a light-receiving element for detecting the presence of recording paper inserted in one of the two guide paths. A pivotable detecting lever is pivoted by the recording paper when the recording paper is inserted in the other of the two guide paths, and the pivotal movement of the detecting lever, in turn, displaces a reflecting plate to a position covering the photo sensor so that light emitted from the light-emitting element is reflected by the reflecting plate to the light-receiving element thereby detecting the presence of paper in the other guide path.
