Abstract
A transfer printer includes a platen drive mechanism for rotating a platen roller facing a print head, and a paper feed mechanism for feeding a paper sheet passing between the platen roller and the head. A ribbon supply device is driven through a transmission mechanism by the drive power of the feed mechanism. The transmission mechanism has a roller holder supporting a transmission gear and arranged to be movable between a transmission position wherein the transmission gear engages an interlocking gear of the feed mechanism and an input gear of the ribbon supply device and a release position wherein the transmission gear is disengaged from the input gear so as to interrupt the power transmission. The roller holder is urged by a spring toward the transmission position, and restricted an excessive movement to the transmission position so that the transmission gear is in mesh with the input gear with a suitable backlash.
