Abstract

PURPOSE:To achieve accurate character cut-out, by calculating a character pitch from the number of maximum print characters included between read-in start information, read-in end point information, and these terminal points and compensating the start and end points from the result of actual measurement. CONSTITUTION:A clock CLH produced by every longitudinal column formed at a pitch counter 48 and an AND gate 54 is taken as a count objective, and a tentative start point pulse obtained from a comparator 36 is received through an OR gate 52 to start count, and a count value is inputted to a decoder 50. This count value is also inputted to a comparator 56 and it produces a coincidence output EQ when the result is equal to a pitch P, and this is inputted to a counter 48 through the OR gate 52. An operation section 60 fetches the count value of counters C1-Cn through a multiplexer 58 to output the bit number of minimum count. This is added to a tentative start point FSP' and a tentative end point FEP' at adders 62, 64 to induce true start point TFSP and true end point TFEP.
