Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
A facsimile apparatus which comprises: a read head for reading information which is to be transmitted from an original paper surface; a record head for recording received information on a recording paper surface, wherein said read head and said record head are constructed to be integral with each other, and are oriented so that said heads read and record from the same planar surface; a first roller rotatably mounted on the opposite side of said planar surface from said read head for being brought into pressure contact through said original paper surface with said read head, and a second roller rotatably mounted on the opposite side of said planar surface from said record head for being brought into pressure contact through said recording paper surface with said record head, wherein said rollers are independently rotatable in both forward and backward directions, and wherein said rollers rotate individually and simultaneously so that said heads can receive a plurality of original papers and recording papers.
