Abstract: An image input device is disclosed that employs a generic interface. Upon connection of the image input device to a host device, an interface control circuit causes the host device to recognize the image input device as a removable device. The interface control circuit then executes a response to the host device indicating that a disk medium is not inserted while an image reading construct is reading an image, converts the digital data to image data of a file format such as MS-DOS that can be read by the host device and stores the data to RAM. The interface control circuit then executes a response to the host device indicating that a disk medium is an inserted state when the image reading construct completes reading of the image.
