ABSTRACT:
A code carried by a recording paper is read out and the code signal is supplied to a data processing control unit. The source data corresponding to this code signal is read out from a data memory unit under instructions from the data processing control unit. An arithmetic operation associated with the source data read out from the data memory unit is performed by the data processing control unit. The result obtained from the arithmetic operation is then recorded in the paper.
