Abstract: A sheet conveying device includes a separation member, a second conveyance member, a third conveyance member, and a first drive control portion. The separation member separates a sheet in contact with a first conveyance member from another at a first position where the first conveyance member comes into contact with the sheet. The second and third conveyance members are respectively downstream of the first and second positions. The first drive control portion stops driving the first conveyance member (1) after the leading edge of the sheet reaches the second position and before the trailing edge of the sheet passes through the first position when the sheet length is not exceeding a specific distance based on a distance between the first and third positions and (2) after the leading edge reaches the third position and before the trailing edge passes through the first position when the length exceeds the specific distance.

Abstract: An image reading device reads an image of an original document and includes a conveyance roller, an image reading section, a first determination section, a second determination section, and a conveyance stopping section. The conveyance roller conveys the original document. The image reading section reads the image of the original document. The first determination section determines whether or not the original document has a punched hole based on the image read by the image reading section. The second determination section determines, upon determination that the original document has the punched hole, whether or not the punched hole is to travel on an edge of the conveyance roller. The conveyance stopping section stops conveyance of the original document upon determination that the punched hole is to travel on the edge of the conveyance roller.

Abstract: A reading device includes a conveyance control section for controlling document conveyance. In a case of double-sided reading of a document and with a cutout document mode applied, the conveyance control section stops a pair of reverse-rotation rollers at a time point when the document has been conveyed by a distance resulting from adding an additional distance, which is predetermined or determined based on a recognized cutout width in the document conveyance direction, to a reference distance since a time point of passage of a rear end of a document-detecting detection part, and thereafter start reverse rotation of the pair of reverse-rotation rollers.

Abstract: A paper feed device includes a paper tray, a set-state sensor, a paper feed unit, and a control unit. The control unit checks an output from the set-state sensor each time before the start of the intermittent paper feed. In the case where no paper feed is detected even after the prescribed number of times of the intermittent paper feed, the control unit determines that a non-feed jam has occurred. In the case where it is detected that there is no paper on the paper tray before the number of repetition of the intermittent paper feed reaches the prescribed number of times, the control unit causes the paper feed unit to terminate the retry processing and determines that, with no paper on the paper tray, it is not the non-feed jam.

Abstract translation: 供纸装置包括纸盘，设定状态传感器，供纸单元和控制单元。 控制单元在间歇进纸开始之前每次检查来自设定状态传感器的输出。 在即使经过规定次数的间歇进纸之后也没有检测到进纸的情况下，控制单元判定为没有进纸卡纸。 在检测到间歇式进纸的重复次数达到规定次数之前在纸盘上没有纸张的情况下，控制单元使送纸单元终止重试处理， 纸盘上没有纸张，不是不进纸卡纸。
