Abstract
Abstract A body member arranged to be supported on a table or other support has a telescope-type magnifying device supported thereon. In one embodiment, the body member has a transversely movable reading material holder adjustable toward and away from the magnifying device to provide focusing. Such holder may be completely removed for use of the magnifying device in viewing other objects below the body member. In another embodiment, a telescope-type magnifying device has up and down movement as well as lateral movement and is used with a stationary reading material holder. This second embodiment has a friction clamp for holding the magnifying device in a selected raised position.
