printing device

Abstract

Abstract PURPOSE:To obtain uniform-quality printings by varying the driving time of a printing hammer according to the moving distance of a carriage. CONSTITUTION:Key information put in a key board 101 is once stored in a key buffer 102 and then orderly read in CPU 103 where a carriage motor, a printing hammer, etc., are driven according to the key information. In short, when driving the carriage, the moving amount of the carriage makes reference to a predetermined moving amount conversion table 105 by a control program 104 according to the key information. At the same time, the data of UP/DOWN counter 107 displaying the present position of the carriage is added to the moving amount by CPU 103, the result is written down in a carriage position register 108, and at the same time the moving amount is stored in the register 118.
