Abstract: PURPOSE: To improve the state of a technique which acquire a sign, especially, a receipt confirmation signature, to use an electroopticall scanner, preferably, a moving beam type or flying spot type scanner to electrooptically acquire the sign, to acquire the sign with reliability so that it can be retrieved later for wide-range pulses, and to conveniently and inexpensively provide a means which identifies a person on a label. CONSTITUTION: Two-dimensional information like a written signature is acquired by an electrooptical scanner 12 and can be reconstituted thereafter. A mutli-row preamble code and mufti-row postamble code means 26 and 28 constitute the signature, and each code has a row identifier, which discriminates which row is scanned with a scanning beam 30 emitted from the scanner 12, and start/stop data which discriminates that each scanning beam traverses the boundary of a space including the signature.
