Stationary hologram scanner.

摘要

A stationary hologram scanner according to the present invention previously divides one light beam into a plurality of parts (switched-over in a time division manner) prior to the incidence of a light beam there-upon, so that a construction, in which only one mirror is installed between a hologram disk and a reading window, is possible, whereby reducing a sectional area of one side portion of an apparatus <!-- EPO <DP n="2"> -->in comparison with the conventional apparatus, an operator can reasonably operate in a seated posture with putting operator's knees below this portion.
