Abstract

PURPOSE:To ensure an easy-to-see input with a reduction of misoperation for a printer-type calculator, by performing a print with push of the unit key after storing the result of registering into a register. CONSTITUTION:The gate G4 stores the contents of the register R1 into the printer driving buffer circuit DR2 through its own gate in case e.g. the ten-thousand key U is pushed after the result of registering is stored in the register R1. In this case, a print instruction is applied to the printer PU by the operation of the gates G1 and D1 to carry out a print. After this, the paper is fed by the gate D2, and the printed figures are confirmed on the printing paper. Thus an easy-to-see input is possible with a reduction of misoperation for a printer-type computer by performing a print while the unit key is pushed.
