ABSTRACT:
In a handy type image scanner, information of an original is observed through an window formed on a case of the image scanner. The handy type image scanner includes a case which encloses a light source for illuminating an original, a reflecting mirror for conducting light reflected from the original to a predetermined direction, and an image sensor for receiving the light from the reflecting mirror so as to input information of the illuminated original. The case includes an upper surface which has a window for observing the information displayed on the original which is being optically read out by the image sensor.
