Abstract

PURPOSE: To increase mechanical durability and make possible the reduction of size and weight by so constituting the device that notches for protruding the tips of lamps in alignment to the moving direction of the scanner are provided to the reflecting mirror provided behind the lighting lamps.
CONSTITUTION: The original lighting device I consisting of a holder 10, reflecting mirror 17 and lamps 13, 14 is provided to the front end part of a read head 23 and imaging lenses 24, 25 and solid-state sensor 26 are provided in the head. The original O being intermittently fed is fed up to the position where contact glass 28 is disposed, where it once stops and is put in the posture to permit read scanning. Here, the lamps 13, 14 possessed by a carrier 22 go on and along with this, the carrier 22 is guided by guide shafts 20, 21 to start reciprocating motion, then the original reading by the self-scanning function of the solid-state sensor 26 is accomplished by way of the imaging lenses 24, 25.
