RECORDING MATERIAL CONVEYING DEVICE AND IMAGE FORMING SYSTEM

To reduce the size of a device comprising a plurality of image reading means.SOLUTION: A lower image reading unit 222 comprises a light receiving unit 226 that receives reflected light from a sheet. The light receiving unit 226 is provided with a plurality of light receiving elements 226A arranged side by side in a direction orthogonal to a conveyance direction of the sheet. An upper image reading unit 221 also comprises a light receiving unit 226 that receives reflected light from the sheet. The light receiving unit 226 of the lower image reading unit 222 is located on the downstream side of an upstream side portion 81 in the conveyance direction of the sheet. The light receiving unit 226 of the upper image reading unit 221 is located on the upstream side of a downstream side portion 82 in the conveyance direction of the sheet.SELECTED DRAWING: Figure 15 【課題】画像読み取り手段を複数備える装置の小型化を図る。【解決手段】下側画像読み取り部２２２は、用紙からの反射光を受光する受光部２２６を備える。この受光部２２６には、用紙の搬送方向と直交する方向に並ぶ複数の受光素子２２６Ａが設けられている。上側画像読み取り部２２１も、用紙からの反射光を受光する受光部２２６を備える。下側画像読み取り部２２２の受光部２２６が、上流側箇所８１よりも用紙の搬送方向における下流側に位置する。また、上側画像読み取り部２２１の受光部２２６が、下流側箇所８２よりも用紙の搬送方向における上流側に位置する。【選択図】図１５
