摘要：
A copying machine is equipped with a transparent document glass table under which a document detecting member is arranged to travel a certain path relative to a document on said document glass table, for detecting either or both the copy density and the size of a document. The detection step is carried out automatically upon movement of a platen cover downward prior to copying.
