Description

上記目的を達成するために、本発明の原稿給送装置は、原稿積載手段に積載された原稿束から分離給送手段により原稿を１枚ずつ分離して給送する原稿給送装置において、前記分離給送手段よりも原稿の給送方向の下流側に配置された複数の第１原稿検知手段と、前記第１原稿検知手段よりも前記給送方向の下流側に配置された第２原稿検知手段と、給送される原稿の斜行量を算出する斜行量算出手段と、原稿の分離給送動作の制御を行う制御手段とを有し、前記第１原稿検知手段の１つが原稿を検知した後に前記第２原稿検知手段で原稿を検知した場合においては、前記制御手段によって前記分離給送手段を制御して給紙の間隔調整を行う一方、複数の前記第１原稿検知手段で原稿を検知した場合においては、前記斜行量算出手段によって複数の前記第１原稿検知手段での原稿検知タイミングの時間差と原稿の給送速度とから前記斜行量を算出すると共に前記制御手段によって前記斜行量に基づいて原稿の分離給送動作を制御することを特徴とする。 In order to achieve the above object, the document feeding device of the present invention is a document feeding device that separates and feeds documents one by one from a bundle of documents stacked on a document stacking unit by a separation feeding unit. A plurality of first document detection means arranged on the downstream side in the document feeding direction with respect to the separation feeding means, and a second document detection arranged on the downstream side in the feeding direction with respect to the first document detection means. Means, a skew amount calculating means for calculating the skew amount of the document to be fed, and a control means for controlling the separation and feeding operation of the document, and one of the first document detecting means is a document . in case of detecting the document by the after detecting the second document sensing means, while performing the interval adjustment of the feeding by controlling the separation feeding means by said control means, a plurality of the first document detection means in case of detecting the document by the skew quantity calculating means Controlling the document separating and feeding operation based on the skew amount by said control means to calculate the skew amount from the time difference and the feeding speed of the document of the document detection timing by the number of the first document detection means It is characterized by doing.

また、上記目的を達成するために、本発明は原稿積載手段に積載された原稿束から原稿を１枚ずつ分離して給送する分離給送手段と、前記分離給送手段よりも原稿の給送方向の下流側に配置された複数の第１原稿検知手段と、前記第１原稿検知手段よりも前記給送方向の下流側に配置された第２原稿検知手段とを有する原稿給送装置を制御する制御方法であって、給送される原稿の斜行量を算出する斜行量算出工程と、原稿の分離給送動作の制御を行う制御工程とを有し、前記制御工程では、前記第１原稿検知手段の１つが原稿検知した後に前記第２原稿検知手段で原稿を検知した場合においては、前記分離給送手段を制御して給紙の間隔調整を行う一方、複数の前記第１原稿検知手段で原稿を検知した場合においては、複数の前記第１原稿検知手段での原稿検知タイミングの時間差と原稿の給送速度から前記斜行量を算出すると共に前記斜行量に基づいて原稿の分離給送動作を制御することを特徴とする。 In order to achieve the above object, according to the present invention, there is provided a separation feeding unit that separates and feeds documents one by one from a bundle of documents stacked on the document stacking unit; An original feeding apparatus having a plurality of first original detecting means arranged downstream in the feeding direction and a second original detecting means arranged more downstream in the feeding direction than the first original detecting means. a control method for controlling includes a skew amount calculation step of calculating a skew amount of the original to be fed, and a control step of performing control of the document separating and feeding operation, and in the control step, the in case one of the first document detection means but of detecting the document by the second document detection means after document detection while performing the interval adjustment of the feeding by controlling the separation feeding means, plurality of the first 1 in the case of detecting the document by the document detecting means, a plurality of the first document And controlling the document separating and feeding operation based from feeding speed of the time difference and original document detecting timing in the knowledge means to the skew amount to calculate the amount of skew.
