ABSTRACT:
A transition code processing system which includes a record member on which is located a plurality of bar code symbols, each of which comprises a data channel and a clocking channel. The record member is inserted into a data terminal device and intermittently driven through a printing station in which a sensing member senses the data channel out of phase with the sensing of the clocking channel and generates signals in response thereto. A circuit coupled to the sensing member will process the generated signals and transmit the processed signals to a utilization device. Upon processing the signals representing the last bar code symbol on the record member, the circuit will generate a control signal for stopping the movement of the record member through the printing station, thereby conditioning the record member for a subsequent printing operation.
