Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
117 words
Facsimile apparatus for transmitting and receiving signals representing dark/light variations on a document comprising: scanning means; document storage means for storing a plurality of document sheets to be scanned for dark/light variations for generating transmitted signals; copy medium storage means for storing a plurality of copy medium sheets for recording dark/light variations represented by received signals; a document feed path from said storage means to said scanning means; a copy medium feed path from said copy medium storage means to said scanning means; and an additional sheet feed path; said copy medium feed path, said document feed path, and said additional sheet feed path merging so as to form a single feed path at said scanning means.
