Abstract: An image reading apparatus comprising: an original reading unit configured to read an image of each of multiple originals placed on an original table in batch by a batch-scan; a cropping unit configured to crop an image of each original from an entire image which is read by the batch-scan; an image output unit configured to output a cropped image of each original; and a control unit configured to control the original reading unit, the cropping unit, and the image output unit, wherein the control unit is capable of selectively executing: an inversion multi-crop process in which an image density of an edge of each original is supposed to be higher than an image density of a reading-area outside of the original, and an area to be cropped is determined on the basis of a difference in the image density between the edge and the reading-area outside of the original; and a non-inversion multi-crop process in which an image density of an edge of each original is supposed to be lower than an image density of a reading-area outside of the original, and an area to be cropped is determined on the basis of a difference in the image density between the edge and the reading-area outside of the original.

Abstract: Provided is an image reading device includes a document transport device that sequentially transports a plurality of documents one by one, and the image reading device sequentially reads the plurality of documents transported by the document transport device one by one. The image reading device includes a document discharge tray, a document discharge detector that detects whether or not a document of the plurality of documents is discharged to the document discharge tray, a notifier that notifies that the document of the plurality of documents discharged to the document discharge tray is forgotten to take, and a controller that activates the notifier if it is determined that a last document among the plurality of documents is read and the document discharge detector detects that the document of the plurality of documents is discharged to the document discharge tray.

CPC classification number: H04N1/00816 , H04N1/00822
Abstract: An image forming apparatus includes a light transmitting member provided at a reading position set in a conveyance path and an opposite plate opposed thereto, and a document being conveyed passes between this opposite plate and the light transmitting member. On an opposing surface of the opposite plate to the light transmitting member, a low brightness area, for example, like a gray color and a high brightness area, for example, like a white color, having a higher brightness than the low brightness area are formed adjacent to each other in a conveyance direction of the document. Then, an image reader sets a home position of a scanning unit to a first position or a second position corresponding to either the low brightness area or the high brightness area to read the document passing through the reading position.
