PURPOSE:To enable to prevent a rear part of a carrier from being levitated due to vibration, by a simple construction, by energizing the carrier toward a rear part guide by the tension of a wire connected to the carrier for the purpose of feeding a ribbon or moving the carrier. CONSTITUTION:The carrier 5 with a printing head 4 mounted thereon is provided with an engaging part 6 slidably engaged with a front part guide 2 and a contact part 7 supported by the rear part guide 3, and the ribbon-feeding or carrier-moving wire 11 supporting at positions proximate to left and right frames is connected to the carrier 5. Both ends of the wire 11 fitted to a pulley 10 rotatably fitted to the carrier 5 are fixed directly to a left-right pair of frames 2, respectively. On one side, the wire 11 is inclined at an angle alpha in the direction intersecting the place connecting the guides 2, 3 as the frames 12 are approached, and on the other hand, the wire 11 is inclined at an angle beta in the direction from the platen 1 toward the rear part guide 3 as the frames 12 are approached. Accordingly, the rear part of the carrier 5 is energized downward by the tension of the wire 11, a roller 7 makes springly contact with the guide 3, and is rearwardly energized so as to be spaced from the platen 1. |
