ABSTRACT:
Facsimile apparatus which graphically records electric signals on recording paper drawn through a recording zone has a linear recording electrode on one side of the zone and a cooperative scanning belt carrying one or more recording styli. The styli are orbitted on the other side of the recording zone by a drive sprocket wheel engaging the belt. At the other end of the recording zone the belt passes over an idler guide which has integral flanges at each end of its semicylindrical body receiving the belt. The guide also has a plunger portion sliding against a spring in a socket on the recorder frame, the spring causing the guide means to tauten the belt.
