Abstract
Abstract The disclosed batch ticket reader is designed for use with bar coded tickets having a complete data message or entry encoded along one edge of the ticket. The reader accepts tickets fed from storage in any of four possible different positions or orientations and detects, error checks, and forwards to a magnetic tape output unit correct data derived from the tickets supplied in any of these four positions. The reader uses two sets of decoding head pairs longitudinally spaced along the ticket feed path on opposite sides thereof. Signals derived from the heads select the one head providing correct data. The data from the selected head is detected, error checked, changed to proper form in dependence on the direction of reading the message, and is supplied to the output unit. Another circuit checks for the provision of a header record preceding a group of tickets and a trailer record following a group of tickets. These header and trailer records are diverted to a container receiving tickets from which improper data is derived so as to identify and segregate by groups all improper tickets. A keyboard unit for supplying manual data entries, a display unit for displaying manual data entries, and a programmed data message length control are also included in the reader.
