Abstract

PURPOSE: To enable the automatical recognition on the set position and the width of a blank sheet, by storing position information on a loaded blank sheet in a memory, and considering a typeprinting operation onto the blank sheet on the basis of the stored information.
CONSTITUTION: A multiprograming unit MPU further shifts a carriage rightwards by one character (one column) and adds +1 to a register R1, to recognize the width of a loaded blank sheet. After multiprograming unit MPU raises the content of the register R1 by +1, the multiprograming unit MPU recoginizes the existence or absence of the blank sheet through an interface PiAa. If there is the blank sheet, the multiprograming unit MPU shifts the carriage by one character, and controls to add +1 to the register R1. Thus, the existence or absence of the blank sheet is recognized, whenever the carriage is shifted by every one character. When the blank sheet is used up, the multiprograming unit MPU stores a value, which is produced by subtracting the value of a register R2 from the value of the register R1, into a register R3, and completes the judgment and control of the blank sheet- loading.
