Abstract
PURPOSE: To enable a smooth printing by providing such an arrangement as a pressing contact force of a recording head of a printer against a recording paper may be made directly by a resilient force of a coil spring connecting a rotatable lever with a carriage having the recording head.
CONSTITUTION: A hang shaft 10 is fixed to a leading end of a lever 9 which may be rotated by a spacified angle of θ around an axis 8. A coil spring 11 is arranged between the shaft 10 and the holding hole 12 made in a carriage 6. Thereby, the printing head 3 always presses against the recording paper 4 under a resilient force from the coil spring 11. When the printing head 3 is moved from the point P toward the direction of an arrow A, the hang shaft 10 is moved from the point S to the point T by an angle of θ. The movable angle θ and a length of the lever 9 are selected in such a way as a pressing contact force of the printing head 3 under a resilient force of the coil spring 11 is set in a range of tolerance, a burden or load other than a friction force required for the printing is decreased to make a smooth printing operation.
