Abstract
A head up-down mechanism in a printer is to be provided wherein, by a simple construction, a carriage is returned up to a printing start position while a thermal head is spaced apart from a platen and at the same time there is performed a paper feed operation and which can thereby improve an effective printing speed. To this end the head up-down mechanism includes a head up-down lever with a thermal head mounted thereon at a position opposed to a platen, the head up-down lever being supported pivotably by a carriage which reciprocates along the platen between both side plates spaced a predetermined distance from each other, an urging member for urging the head up-down lever in a direction in which the thermal head comes into abutment against the platen, and a head up-down cam which is moved by abutment thereof against each of the side plates and which causes the head up-down lever to turn so that the thermal head comes into or out of contact with the platen.
