Abstract
An input apparatus for a digitizer tablet includes a lens section, an input operation section and an operation mechanism. The lens section has a mark formed at the bottom to indicate the position to be input, and a pickup coil wound around its peripheral portion. The input operation section has input operation switches and holds the lens section in such a way that the lens section is movable up and down with respect to a digitizer table. The operation mechanism includes a slide lever, a hook member, arm sections and a coupling rod. The operation mechanism is provided in the input operation section to move the lens section toward or away from the digitizer table.
