ABSTRACT:
A print head mounting mechanism for a printer is disclosed by which positioning of a print head in the forward and backward directions, leftward and rightward directions, and upward and downward directions with respect to a carrier can be achieved readily. The mounting mechanism includes a print head mounting plate secured in an integrated relationship to the carrier and having a predetermined thickness. The print head mounting plate has a U-shaped recess having a predetermined width and a predetermined depth. A mounting section for fitting in the U-shaped recess is provided on the print head. The print head is mounted on the carrier in an accurately positioned condition by fitting the print head mounting section into the U-shaped recess and urging the print head in the rearward direction and also in the downward direction by a wire spring.
