Description

本発明は、搬送路上に搬送される原稿に光を照射する第１光源を有し、該原稿からの反射光に基づいて該原稿の移動を検知する検知部と、
前記搬送路上に搬送される原稿に光を照射する第２光源を有し、該原稿からの反射光に基づいて該原稿を読み取る読み取り部と
を有し、
前記読み取り部は、前記検知部から前記原稿の搬送方向にずれた位置に、前記搬送路に対して前記検知部と同じ側に設けられており、
前記第１光源及び前記第２光源のうち一方は、前記搬送路に沿った方向において前記第１光源及び前記第２光源のうち他方が位置する側とは異なる側に向けて光を照射する
ことを特徴とする。 The present invention includes a first light source that irradiates a document transported on a transport path with light, and a detection unit that detects the movement of the document based on the reflected light from the document.
It has a second light source that irradiates the document transported on the transport path with light, and has a reading unit that reads the document based on the reflected light from the document.
The reading unit is provided at a position deviated from the detection unit in the transport direction of the document, on the same side as the detection unit with respect to the transport path.
One of the first light source and the second light source irradiates light toward a side different from the side where the other of the first light source and the second light source is located in the direction along the transport path. It is characterized by.
