摘要：
A pair of registration rollers align a leading edge of a recording medium having a transparent section and a non-transparent section. A boundary sensor detects a boundary between the transparent section and the non-transparent section. The boundary sensor is provided on a downstream side of a direction of conveying the recording medium by the registration rollers.
