Abstract

PURPOSE: To detect the subsequent printing line through reading of letters on the printed lines with a sensor preventing letters from skipping the right line by inhibitting the reading output while the sensor faces the upper end of the line corresponding to the subsequent letter to be printed.
CONSTITUTION: In case the preceding letter jumps over to the line corresponding to the letter about to be printed as shown by the letter signal A, skipping of the line will occur as it stands. The reading of the letter is inhibitted so as not to detect thereof. After the detection of the timing mark signal α, FF22 is set through a logic multiply between the invertion signal of the inhibitting signal and the letter signal A. Consequently Q output rises and the ogical multiply between the output and the timing mark signal β generates the output pulse P in the AND circuit 33. This output is applied to the setting circuit 34 and the subsequent letter placed on the right printing line. Thus, the setting is made.
