Cutter Drive Mechanism, Cutter, and Printer

摘要

A cutter can move a movable knife by two cutter drive gears without the movable knife becoming skewed. The cutter 10 of a mobile printer 1 has a fixed knife 11, and a cutter drive mechanism 32 that moves the movable knife 31 straight to and away from the fixed knife 11. The cutter drive mechanism 32 has two cutter drive gears 51 that are driven synchronously, and a cutter drive plate 54 disposed between the two cutter drive gears 51 and the movable knife 31. The two cutter drive gears 51 cause the cutter drive plate 54 to move to and away from the movable knife 31 on a longitudinal axis Y (direction of travel), thereby moving the movable knife 31 to and away from the cutter drive plate 54. If the cutter drive plate 54 becomes skewed when the two cutter drive gears 51 move the cutter drive plate 54, the guide mechanism 81 prevents skewing of the movable knife 31.
