Abstract

PURPOSE: To have an automatic line feed with no occurrence of the line feed code, by supplying the English letters, figures and others after printing in duplication the erasion mark onto the character already printed via the erasion key.
CONSTITUTION: With operation of the character key through keyboard 1, the key code corresponding to the character is generated as the data output along with generation of the strobe pulse. Thus the key code is stored in RAM2, and at the same time AND circuit 4 is satisfied with address counter 3 counted up. Here the misinput is noticed when the printing is carried out from A through J as shown in (a), and five characters are erased via the erasion key. Under these conditions, erasion code detecting circuit 6 is satisfied with FF circuit 7 set. At the same time, AND circuit 5 is satisfied, and thus counter 3 counts down to "5". Then the back slash meaning the erasion mark for the five letters is printed in duplication as shown in (b). When the "1" key meaning the correct data is pushed, the output signal of AND circuit 9 performs the action for line feed.
