Abstract
Abstract A laser beam emitted from a semiconductor laser is radiated and scanned on a bundle of paper materials which is being conveyed, and the laser beam reflected by the bundle is received by a plurality of photocells to be converted to electrical signals. A signal synthesizer synthesizes the electrical signals output from the photocells. A binary circuit binarizes the synthesized signal to generate a boundary signal corresponding to a boundary between packs included in the bundle. A CPU detects the number of packs included in the bundle on the basis of the number of boundary signals.
