Abstract
An image read-out apparatus includes a main scanning device for scanning a sheet carrying an image recorded thereon with a light beam in a main scanning direction and obtaining light carrying the image information from the sheet, a sub-scanning device for moving the sheet with respect to the light beam in a sub-scanning direction approximately normal to the main scanning direction, and a light detector for detecting the light obtained from the sheet. The light detector comprises a long photomultipler having a light receiving face extending along the main scanning line and positioned close to the sheet.
