Abstract
An image reader is disclosed in which, upon application of an illuminating light beam to an original by an illuminating optical system, a light beam reflected from the original is applied through a contracting optical system to a line sensor for converting an optical image of the original into an image signal. The image reader has a first mirror provided for said original to reflect said light beam reflected from the original; a repetitive reflection optical system including a pair of parallel mirrors for causing said light beam reflected by the first mirror to go and return at least once in a reflection mode; and a second mirror provided for a contracting optical system to reflect the light beam thus caused to go and return towards the contracting optical system.
