Optical scanner, code reader and bar code reader having increased degree of freedom in placement of optical parts

摘要

A code reader, comprising a bottom part (1) embedded in a surface of a counter (2) and emitting a first scanning pattern to read a code optically; a side part (4), positioned transversely, for example vertically, to the bottom part, and emitting a second scanning pattern different from the first scanning pattern to read the code optically; and a speaker (15) positioned facing a user at a top center of the side part to emit a sound indicating to the user that the code has been read.
