ABSTRACT:
A printer comprises a frame having top, bottom, left and right surfaces, a base disposed along the bottom surface, and a pair of bearings each connected to the base and having a recessed portion. A platen is supported between the left and right surfaces of the frame to undergo rotation. A print head is supported between the left and right surfaces of the frame to undergo pivotal movement about a rotational axis into and out of contact with the platen and for printing on a recording paper fed between the platen and the print head. The print head has a pair of support shafts disposed along the rotational axis each for engagement with one of the recessed portions of the bearings. When the support shafts of the print head detachably engage with the recessed portions of the bearings and the print head is pivoted about the support shafts, the print head undergoes pivotal movement into and out of contact with the platen without being detached from the bearings.
