摘要

PURPOSE: A watching sight in a narrow area of a reader robot is provided to project a sentence in an encircled gill regardless of distance or position of the sentence printed matter. CONSTITUTION: An object lens(2) is fixed at the inner front portion of a handle(1) made by a pipe, and a ring shape electric bulb(3) surrounding to the object lens(2) is fixed at the front portion thereof and a reflex mirror(4) is provided.
