Abstract
A paper-loading mechanism for a document duplicating machine, which is driven by a reciprocating part in a document duplicating machine and performs periodical paper-loading control on a paper loader of the document duplicating machine, comprises an actuating unit, a transmitting unit, a paper-feeding pushrod, and a torsion spring. The actuating unit is utilized to provide reciprocating motion for the paper-loading mechanism for a document duplicating machine and is pushed by the reciprocating part along a line parallel and adjacent to one end of the trajectory of the reciprocating part. The transmitting unit is connected with the actuating unit and is used to transfer the reciprocating motion from the actuating unit to the feeding pushrod. The paper-feeding pushrod is located along one side of the paper loader of the document duplicating machine and is rotated along its own longitudinal central axis. The torsion spring is used to restore torsion energy and to drive smoothly the feeding pushrod, with one end thereof connected with the feeding pushrod and another connected with the transmitting unit.
