Abstract
A mechanism for compensating for different thicknesses of record media at a printing station utilizes a platen supporting or carrying assembly which is pivotable to move the platen toward the print head. Another supporting assembly, also pivotable, is provided to carry a record media drive roller and is interconnected with the platen supporting assembly by means of a pin and slot arrangement to effect a substantially equal gap at the platen-print head and at the pressure roller-drive roller. A first cam member is rotated to engage with and to swing the platen supporting assembly into printing position and a second cam member is connected with the first cam member and rotated thereby to maintain the assembly in printing position.
