description To provide a conveyance device capable of reducing a movement amount in receiving operation.SOLUTION: A conveyance device includes a correction roller 32 which corrects positional displacement of paper P, a first CIS 33, a second CIS 34 and a skew detection sensor 35 as detection mechanisms, and a control unit which controls a return operation of the correction roller. The control unit calculates a positional deviation amount of the paper P on the basis of a paper position detected by the detection mechanisms, the correction roller corrects the positional deviation of the paper P on the basis of the calculated positional deviation amount of the paper P, the correction roller performs a receiving operation which moves the correction roller from a reference position by the positional deviation amount before the returning operation, and the control unit learns the calculated positional deviation amount of the paper P when the paper P is conveyed and moves the correction roller to a previously learned learning position in start of the conveyance operation of the paper P.SELECTED DRAWING: Figure 2 【課題】迎え動作時の移動量を低減することのできる搬送装置を提供することを課題としている。【解決手段】用紙Pの位置ズレを補正する補正ローラ32と、検知機構としての第一CIS33、第二CIS34、および、斜行検知センサ35と、補正ローラの戻し動作を制御する制御部とを有し、制御部は、検知機構が検知した用紙位置に基づいて、用紙Pの位置ズレ量を算出し、補正ローラは、算出した用紙Pの位置ズレ量に基づいて、用紙Pの位置ズレを補正し、補正ローラは、位置ズレ量の分だけ、基準位置から移動する迎え動作を、戻し動作の前に行い、制御部は、用紙Pを搬送した際に、算出した用紙Pの位置ズレ量を学習し、用紙Pの搬送動作開始時に、補正ローラをあらかじめ学習した学習位置へ移動させる搬送装置であることを特徴とする。【選択図】図2
