Hand held bar code reader with input and display device and processor |
摘要 |
A scanning head for reading bar code signals including 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 manually actuated input and display device. A microprocessor in the head controls the operation of the various components. A transmitter and receiver may be located in the scanning head for communication with a central computer, and a battery may be included in the head as a power supply so that the scanning head need not be connected by a cable to a terminal.
