ABSTRACT:
In an apparatus for scanning an original image-bearing sheet, including a transparent sheet-retaining plate, below which are a sheet-scanning optical system, a size-detection arm having sensors for measuring an original sheet retained on the plate, and a blower for introducing cooling air into the space under the plate, airstream guides which divert and redirect the cooling air flowing from the blower are provided on the size-detection arm. The airstream guides properly distribute the cooling air beneath the plate, whereby the plate is efficiently cooled.
