ABSTRACT:
Disclosed is a portable optical character recognition system which may be used as a point-of-sale or inventory taking system which operates from battery power and may be moved from place to place without difficulty. The system includes an edit and sequencing system which guides the operator in its use, alerting the operator when the proper sequence of input is not used and when an incorrect reading has been made. The system includes visual read out and tape cassette recording of the input to the system to keep a permanent record thereof. A power conserve circuit is incorporated into system to turn the system off in between the reading of lines of data yet retain the proper sequencing when reading is continued.
