ABSTRACT:
A sheet thickness sensing apparatus adapted to sense variations in thickness of sheet materials or documents such as printouts, invoices, and direct mails irrespective of dimensions of each document. The thickness sensing apparatus includes a main body, a sensor unit, a sheet light source, a photosensor, a douser or a light intercepting member, a crank, a motor, and a conveyor table. The main body is so supported on a slide rod as to move in one direction. The slide rod is in turn supported by support plates so as to move in a direction perpendicular to the direction of the main body. The sheet thickness of each document is optically and mechanically sensed.
