ABSTRACT:
An ink ribbon feeder wherein a feed roll support section rotatably supports an ink ribbon feed roll and a take-up roll support section rotatably supports a take-up roll support section; a first driving section turns a take-up roll to wind the ink ribbon in an ink ribbon take-up direction, and a second driving section turns the feed roll in the opposite direction of the first driving section, to apply a tension to the ink ribbon. The first driving section and the second driving section are disposed on the same side of both the take-up roll and the feed roll in the ribbon take-up direction. The recording unit, inclusive of the recording head, the ink ribbon feed roll and the take-up roll are mounted in various ways to equalize the tension over the width of the ink roller.
