ABSTRACT:
A micro-reader which comprises a generally rectangular box-like, flattened casing a slide frame slidably supported by the casing for movement between retracted and extended positions, a light-permeable screen mounted on and supported by the casing for movement between folded and erected positions, and a reflective mirror member carried by the slide frame for movement between laid-down and upright positions. When the micro-reader is not in use with the slide frame, the screen and the mirror member being held in the retracted, folded and laid-down positions, respectively, the screen and the mirror member constitute cover members for covering the top and bottom of a space between the casing and the slide frame, but when the micro-reader is in use with the slide frame, the screen and the mirror member held in the extended, erected and upright positions, respectively, the mirror member confronts the screen at a predetermined angle while lying in a plane different from the plane which is occupied by the mirror member when in the laid-down position.
