An image information apparatus includes image input devices that read images on both sides of an original in parallel, a local memory that temporarily stores one or more image data read by the image input devices, and a hard disk device that stores the same image data that is stored in the local memory. A PCI bus, which serves as a transfer path for the image data on both the sides, and a PCI transfer controller, which controls communication via the PCI bus, are provided between the image input devices and the local memory. In addition, transfer units, which pass the image data on both the sides read by the image input devices to the PCI transfer controller in parallel and individually, is provided on the image input devices.
