摘要：In an ink-transfer thermal printer the mechanism for switching from a thermalhead (4) head-down state (in which printing takes place with contact between the thermalhead (4), a thermo-ink ribbon (1) and paper (7)) to a head-up state (in which printing doesnot take place, with no such contact) utilizes a cam (24,124) and a cam-follower (25,125).The printer has a winding-up mechanism operating a take-up reel (2) for an ink-transferribbon (1). Wind-up or take-up of the ribbon (1) is effected or not effected in accordancewith the state (head-down or head-up) of the thermal head (4), so that feeding of the ink-transfer ribbon during a spacing operation (the head-up state) is prevented, thereby toeconomise on use of the ink-transfer ribbon. The cam action employed reduces noisecaused by the switching action. The mass of moving parts associated with the switchingoperation is small, so that a high switching speed can be achieved.
