Abstract
A hollow platen roller common for reading and recording heads is provided. A cam shaft is disposed in the hollow platen roller and the cams are provided at the opposite ends of the hollow platen roller. The reading and recording heads are disposed in operation with the cam. Through the operation of the cam, the reading or recording head is selectively contacted with the outer surface of the hollow platen roller.
Claims7
A facsimile apparatus comprising:
- a hollow platen roller having an outer surface and inner walls defining a hollow space therein;
- a cam shaft extending through the hollow space in said hollow platen roller and mounted for rotation independent of said hollow platen roller;
- a cam attached to an end of said cam shaft extending outside one end of said hollow platen roller;
- a reading head and a recording means arranged in spaced apart relation from each other around the outer surface of said hollow platen roller, said recording means including a recording head add recording paper holding-down means associated therewith, said reading head and said recording means being selectively movable to positions spaced from and in contact with paper held on the outer surface of said hollow platen roller for reading and recording operations thereon,
- wherein said cam is coupled to said reading head and to said recording means and is operated to selectively move them into contact with paper on the outer surface of said hollow platen roller, and
- further wherein said cam is operable in a plurality of positions including a waiting position wherein said reading head and said recording means are spaced from the platen roller, a transmitting position wherein only said reading head is in contact with said platen roller and a receiving position wherein only said recording means is in contact with said platen roller.
