To realize a spectral characteristic acquisition device based on a plurality of arrayed spectral sensors at low cost by means of a composition that does not cause wrinkles and floating to occur.SOLUTION: The spectral characteristic acquisition device comprises: first conveyance means for conveying an object in a prescribed conveyance direction; color data acquisition means in which a plurality of spectral sensors for receiving reflected light of irradiated light from the object and acquiring the color data of the object are arrayed in the conveyance direction; second conveyance means for conveying the color data acquisition means in a direction intersecting the conveyance direction; spectral characteristic calculation means for estimating the spectral characteristic of the object on the basis of the color data; and tensile force generation means for causing a tensile force to occur to the object in a color data acquisition region, out of the first conveyance means, that acquires the color data of the object.SELECTED DRAWING: Figure 6 【課題】配列された複数の分光センサによる分光特性取得装置を、記録媒体の皺や浮きを発生させない構成で安価に実現する。【解決手段】対象物を所定の搬送方向に搬送する第１の搬送手段と、照射された光の前記対象物からの反射光を受光して、前記対象物の色データを取得する複数の分光センサを前記搬送方向に配列する色データ取得手段と、前記搬送方向と交差する方向に前記色データ取得手段を搬送する第２の搬送手段と、前記色データに基づいて、前記対象物の分光特性を推定する分光特性算出手段と、前記第１の搬送手段のうち、前記対象物の色データを取得する色データ取得領域において前記対象物に所定の張力を発生させる張力発生手段と、を備える。【選択図】図６
