IMAGE READER, IMAGE READING METHOD, AND IMAGE READING PROGRAM

PROBLEM TO BE SOLVED: To suppress provision of unnecessary images to other devices and reduce the performance of unnecessary image processing, in the other devices. SOLUTION: The image reader includes: an input receiving part 101 receiving designation input of a non-coexistence mode in which originals of the same size are read, or a coexistent mode in which originals of different sizes are read; an original reading part 106 for reading the image of the original; an original conveying part 201 performing conveyance preparing operation that the original which has been read is ejected and the next original is conveyed; an original size detection part 203 for detecting the size of the original; a read preparing operation part 105 for performing read preparing operation; and an operation controller 103 for performing parallel operation control when receiving the designation input of the non-coexistence mode, and performing sequential operation control when receiving the designation input of the coexistent mode. The operation controller 103 switches the control, from the parallel operation control to the sequential operation control, when the size of the next original is different from the size of the original read, immediately prior, even when the designation input of the non-coexistence mode is received.
