Abstract
An aligning device is provided in a paper transport path in a printer, for correcting a recording paper to be parallel to the paper transport path. The aligning device has a pair of guide members (17, 18) that are shifted in a lateral direction to the paper transport path by a drive mechanism (21), to push side edges of the recording paper, and a stopping plate (19) for stopping the guide members at an aligning position. The drive mechanism is constituted of a cam shaft (28) rotated by an aligning motor, a pair of swing levers (29, 30) for converting rotational movement of the cam shaft into swinging movement, and a pair of sliding levers (31, 32) that slide in the lateral direction with the swinging movement of the swing levers. The guide members are mounted on pivot pins (31d, 32d) of the sliding levers, so the guide members may incline relative to the parallel direction to the paper transport path.
