<p>In a laser scanner for a bar code reader which incluces a laser source (41), laser beam scanning means (31, etc.) for scanning a bar code (B) of an object to be sensed by the laser beam outgoing from the laser source in a specified direction, a projection window (25) for applying this scanning beam to the bar code of the object to be sensed and optical detection means (51) for detecting the signal beam reflected from the bar code, the laser beam scanning means and the optical detection means described above are integrally assembled into the same base (20) and the outgoing window is supported by a transparent support member (23, etc.) on the base.</p> |
