PHOTOGRAPHIC COPYING APPARATUS

摘要

A photographic copying apparatus wherein the shutter blade is moved to open position by the frames of color filters whenever a filter pivots in a direction to move out of registry with the light-admitting opening. The filters are pivoted by rotary electromagnets which are deenergized when the respective filters extend across the path of incoming light. The shutter blade is biased to closed position and is pivotable about the common axis of the filters.
