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 structure of a laser barcode scanner includes a laser diode, a collimator, a standing cylindrical lens, a light condensing lens, and a linear sensor. The laser diode provides a laser light which passes through a collimator to form parallel point-shape laser beam. Then, the point-shape laser beam passes through the standing cylindrical lens to become a linear-shape laser beam perpendicular to the standing cylindrical lens. Thereafter, the linear-shape laser beam is projecting on a barcode and then the laser barcode image will be reflected back and focused to the linear sensor by the light condensing lens. The linear sensor will convert the reflected laser barcode image into electronic signals. Then, the electronic signals will be decoded by a decoder into numbers and/or characters represented by the barcode, thereby completing the scanning function of the whole laser barcode scanner.

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.

Abstract: The present invention relates to a full range bar code scanner primarily comprising a scanner housing inside of which a light source, a lens set and a CCD-sensing device are mounted. The light source emits light to reflect upon a bar code in front thereof. Thereafter, the created reflection rays are focused after passing through the lens set so that the image of the bar code is formed on the CCD-sensing device and converted into digital data for use after being read by the CCD-sensing device and decoded by an electrical circuit. This improvement is characterized in that a spectroscope is mounted at the path of the reflection rays in front of the lens set. One side of the spectroscope opposite to the lens set is constructed as reflection face with reflection effect. At least one secondary reflector is installed near the spectroscope.

Abstract: The present invention relates to a compulsory discharging device for exhaust of vehicle of the type in which a driving motor which has a propeller is mounted at the end portion of the exhaust pipe such that the exhaust within said exhaust pipe can be compulsorily discharged. The operation of the driving motor is controlled by a digital controller which uses a signal line to pick up the frequency of a high voltage line of an igniting coil. The rpm of said driving motor can be proportionally controlled with respect to the rpm of the engine. The output shaft of the driving motor is coaxially mounted with a propeller and a mixing propeller with which the exhaust can be mixed with fresh air to reduce the concentration of the exhaust. Then the diluted exhaust is discharged. The exhaust generated from the combustion within the cylinder can be effectively and completely withdrawn such that the performance of the engine can be increased. The residue of carbon is reduced and the power of the engine is increased.
