ABSTRACT:
A feeder of continuous documents for a copy machine comprising an upper frame having a pair of support walls, a cover formed at one end of said upper frame and provided at its upper end with an extension, and a lower frame adapted to define a path for travelling the documents and provided at both sides thereof with a pair of extensions extending beyond the other end of the upper frame. A tractor is fixedly mounted to a drive shaft mounted to the lower frame to be driven by the drive force of a motor and formed of a circular shape to increase the concentration of forces of drawing the documents. The motor drives according to the control of a motor driving unit. In order to supply a control signal to the motor driving unit, at least two sensors are provided. The feeder provides drawing the documents more powerfully and thus feeding them precisely. By virtue of the provision of several sensors, the feeder can be used for the case of narrow documents.
