Abstract
PURPOSE: To prevent a printing head from being overheated and lengthen its lifetime, by attaching a temperature sensor to the printing head or a carriage and controlling the velocity and timing of printing depending on a detected temperature.
CONSTITUTION: A printing head 3 mounted on a carriage 4 is moved in parallel with the surface of paper 2 by a driving motor 5. At the same time. a corresponding wire is caused by a magnet in the head to collide against the paper 2 to print a character. The rise in the temperature of the head 3 above a prescribed level is detected through a temperature sensor 6 and a detection circuit 7 to apply a printing velocity fall instruction to a printer control circuit 9. The rotational frequency of the carriage driving motor 5 is reduced through a driving circuit 11 so that the velocity of printing coincides with the value of a printing velocity setting circuit 8. At that time, driving power frequency is reduced by an electromagnet driving circuit 10. The printing velocity of the printing heat 3 is thus diminished to decrease its calorific value.
