Abstract: In an apparatus and a method for acquiring and reading optical codes, the indication of the reading result is carried out projecting a luminous figure onto the optical code, that is to say in the position on which the attention of the operator is focused. The luminous figure can have an information content also more complex than the simple indication of the end of the reading.

Abstract: The invention relates to an optical device for aiming along an optical axis and visually indicating a reading area, comprising at least an illuminating assembling acting on a portion of the reading area along an optical emission path. The illuminating assembly comprises a light beam emitting source, a diaphragm having a preset shape, such diaphragm being effective to select a portion of the light beam generated by said emitting source, and a converging lens placed, on the optical emission path, downstream of the diaphragm and adapted to collimate the shaped light beam coming from the diaphragm and project it onto a portion of the reading area. The device of this invention is at once economical and accurate (i.e. capable of producing sharp images), thereby providing the user with a clear cut indication of the reading area being aimed regardless of the distance of the latter from the device.
