Abstract: The multi-line barcode scanner with no moving parts includes a light source, a light condensing lens and a linear light receiver. When scanning light beams (maybe linear or strip-shaped light beams) emitted from the light source are projecting onto a barcode, the reflected images thereof are focused onto the linear light receiver by the light condensing lens. The characteristics of the structure are that at least one beam splitter and reflectors are disposed at the projecting path from the light source converted into scanning light beam to the barcode, so as to enable the scanner to project two or more scanning light beams onto a same barcode in a non-overlapping manner, thereby selecting a complete barcode image for decoding at a fastest speed and for further increasing the barcode reading rate from the barcode at different angles or positions.

Abstract: A barcode scanner includes at least a laser emitter, a collimator, a light condensing lens and a linear light receiver. When the scanning light beams from the laser emitter are projected onto a barcode through the collimator, a barcode signal is produced from the reflected image thereof focused onto the linear light receiver through the light condensing lens. The characteristics thereof are that at least one beam splitter and reflector are disposed at the projecting path of the scanning light beams from the laser emitter and the collimator to barcode, so as to enable the scanner to act as a multiple light sources structure, thereby distributing the scanning light beams more evenly with lower production cost and material.

Abstract: A light source mechanism of a barcode scanner includes a laser diode as the point type light source, a collimating lens and a standing cylindrical lens in front of the laser diode. A mirror or a thin-film coating prism can be installed in front of the collimating lens to have the light beam from the collimating lens be reflected at least once to go out in horizontal direction. The reflected light beam from barcode passes through a condensing lens and is received by a linear receiver (CCD or CMOS sensor, for example) and is converted into electrical signals, and decoded by a circuit to get the data.
