Abstract
In an image information reading apparatus according to the present invention, a scanner for reading an image is driven along the surface of a desired image sheet to scan the same, by means of a drive unit, in a manner such that the scanner is opposed to the sheet. The scanner is composed of a fluorescent lamp for applying a light beam to the sheet and a photoelectric converter for reading the light reflected from the sheet, and is housed in a case having a transparent cover which faces the image sheet. The fluorescent lamp, which is housed in the case, cannot be influenced by a temperature change outside the case, so that it can expose the sheet surface with a uniform illuminance.
Claims9
An apparatus for reading an image from an image data-containing sheet, comprising:
- support means for supporting the sheet mounted thereon;
- first illuminating means for illuminating the sheet with light, said first illuminating means extending in a first direction which is parallel to a surface of the sheet;
- first housing means for housing said first illuminating means so as to seal said illuminating means therein, said first housing means including a transparent section through which the light emitted from said first illuminating means and is directed toward the sheet;
- photoelectric converting means, which extends parrallel to said first direction, for converting the light reflected from the sheet into electric signals;
- and
- driving means for simultaneously driving said first illuminating means and said photoelectric converting means in a second direction which is parallel to the surface of the sheet and is perpendicular to said first direction.
