Narrow-bodied, single- and twin-windowed portable laser scanning head for reading bar code symbols |
摘要 |
A scanning head for reading bar code symbols includes a laser source producing a beam which is scanned across a symbol to be read by a moving mirror arrangement, and a photodetector responsive to light reflected from the symbol. The signal from the photodetector is digitized and decoded to recover bar code data. The scanning head includes a keyboard for entering data, and a display from showing data, and a microprocessor in the head controls the operations of the various components. A transmitter and receiver may be located in the scanning head for communication with a central computer, and a battery included in the head as a power supply, so that the scanning head need not be connected by a cable to a terminal.
