Posture detecting device, recording apparatus including the same, lenticular sheet, and method for detecting posture of medium

摘要

There is provided a posture detecting device including: a detecting mechanism movable in a scanning direction relatively to a medium to detect a detection target; and a posture determining mechanism determining a tilt of the medium from a reference posture based on a detection result of the detection target, wherein as the detection target, the medium has a plurality of first detection targets each extending in an intersecting direction intersecting with the scanning direction at a predetermined angle and arranged at equal intervals in the scanning direction; and a plurality of second detection targets each extending in the scanning direction and arranged at equal intervals in the intersecting direction, under a condition that the medium is in the reference posture.
