Sensing device for end of recording medium

摘要: PURPOSE:To enhance the reliability in sensing film end by performing it through comparison of detection signals given two sensors reflective type. CONSTITUTION:A recording medium 22 such as ink doner is provided at its part with marks 23, 24 having different reflexibilities positions said width direction, and equipment furnished reflex type 29, 28 to sense these a judging means judge whether 27, are mating marks, comparing from each other. According this arrangement, which compared other know that reached, can be enhanced regardless color transcription on using relatively great reflexibility.
