Abstract
An improved thermally sensitive printer for recording characters on a thermally sensitive medium is provided. An exothermic printing head includes a substrate and a plurality of selectively energized resistance elements supported on the substrate, the resistance elements being energized during a printing operation to print characters on a thermally sensitive medium in contact therewith. A rotary platen is provided for bringing the thermally sensitive medium into printing contact with the resistance printing elements to thereby effect printing on the thermally sensitive medium during a printing operation. The rotary platen is also adapted to incrementally advance the thermally sensitive printing medium after each printing operation. An oscillatory drive motor is provided for producing a reciprocating rotary driving force and a rotary motion transformer is coupled intermediate the oscillatory driving motor and the rotary platen for rotating the rotary platen through a predetermined pitch in response to said reciprocating rotary drive of said oscillatory driving motor to thereby intermittently advance by a predetermined distance the thermally sensitive medium after each printing operation.
