Abstract

PURPOSE:To make the quantity of deflection of a spring and a gap between the platen and the head point adjustable in accordance with a desired printing pressure in a spring charging type dot printer by a method wherein a stopper for adjusting the quantity of deflection of the spring is provided in a unitary body with a housing. CONSTITUTION:In the armature 19 fixed to a plate spring 18 being sandwiched the stopper 24 of a regulating rod 22. The quantity of deflection of the plates spring between the 1st yoke 16 and the 2nd yoke 17, a quantity of return is controlled by 18 may be smaller in printing on single paper than in printing on copying paper. When a knob is turned right (or left), the knob 7 moves to the front relatively to a back plate 5 and the regulating rod 22 moves further to the front. In other words, the screw pair of the outer periphery of a screw part 10 is of a right-handedly threaded screw while that of the inner periphery is of a left-handedly threaded screw and the relation between the knob 7 and the regulating rod 22 comprises an accelerating mechanism. The regulating rod 22, the housing 1 and a face plate 2 comprise a monolithic structure and a guide part 3 also accelerates and advances by the same distance as the stopper 24 does.
