Abstract
PURPOSE: To provide a high-quality printing of uniform print density by detecting hammer flight velocity and directly controlling hammer impact velocity.
CONSTITUTION: A decoder 1 decodes printing sheet number information and printing head position information of a printer and generates printing pressure information corresponding to the magnitude of copy sheet number and of type printing area. A digital signal from the decoder 1 is converted into an analog signal by a converter 2. A comparator 3 is fed with the analog signal and the output of a hammer velocity detection mechanism 6. The comparator 3 and the mechanism 6, together with a driver circuit 4 and a hammer magnet 5, constitute a hammer flight velocity control circuit 7 for controlling hammer flight velocity at a value conrresponding to the analog signal from the converter 2.
