Abstract
A thermal printing apparatus includes a platen about which a sheet of paper is circumferentially embraced; a head transfer carriage mounted on guide rails of the apparatus for slidable movement in the lengthwise direction of the platen; a thermal head assembly mounted only on one guide rail so as to move with the head transfer carriage in the lengthwise direction of the platen while also being adapted to pivot about the guide rail toward and away from the platen, such that a tape from a tape cartridge is positioned between the thermal head assembly and the paper so that as the thermal head assembly moves along the platen, it selectively heats the tape in response to an information signal to transfer the pigment from the tape onto the paper and thereby record visual information on the paper; a tape clamp device including a lever pivotally mounted to the apparatus, an elastic plate fixedly mounted to the apparatus, and a spring which biases the lever toward the elastic plate to clamp the tape therebetween during movement of the thermal head assembly in the recording operation; and another tape clamp device including a lever pivotally mounted to the head transfer carriage, an elastic plate fixedly mounted to the carriage and a spring which biases the lever toward the elastic plate to clamp the tape therebetween during movement of the thermal head assembly in the carriage return operation.
