  • Publication number: 20020057465
    Abstract: This image input apparatus comprises conveying mechanisms 12 to 15 for conveying a document in a sub-scanning direction; a photoelectric transfer unit 10 for reading the document to be conveyed; a flat bed 70 mounting the document; a screen 3 provided at a reading position of the photoelectric transfer unit 10; and movable optical units 2, 5 for sub-scanning the document on the flat bed 70 and projecting images of the document on the screen 3. The document on the flat bed is read by use of the photoelectric transfer unit of a fixed ADF, and the screen is provided at a reading position of the photoelectric transfer unit, and the images of the movable optical unit are projected on this screen. Thus, a connection cable of a read part of the flat bed is not required, and it is possible to restrict the occurrence of the EMI which may cause the trouble in other devices.
