PURPOSE:To stabilize the place and distance of a part required to be megnified and partially magnify the fine characters to be read or written by so forming the titled device that it is made freely mountable to a read bar and a writing means, freely adjustable of visual angle and fixable. CONSTITUTION:When the spherical root 6 of a magnifier 1 is rotated, an inclusively fitting part 4 can be opened or contracted. To change the magnifier 1 to an arbitrary universal plane, a screw 3 is rotated to loosen. To secure the same to a desired arbitrary plane, the screw 3 is counter-rotated to tighten. |
