Paper separating apparatus of printer
First Claim
1. A paper separating apparatus of a printer for preventing a paper jam from occurring when a sheet of paper which is passing between a transfer roller and a fusing roller of the printer is wound around the transfer roller, the paper separating apparatus comprising:
- a separating member installed adjacent to an exit side of the transfer roller and under a path along which the paper is discharged and fixedly coupled to a pair of bearing guides which rotatably support opposite ends of the transfer roller to be operative to pivot by a predetermined angle together with the bearing guides;
at least one guide roller installed at an upper surface of the separating member for guiding discharge of the paper;
a pivot restricting mechanism which restricts a pivot angle of the separating member and the bearing guides; and
an elastic force applying mechanism which applies an elastic force in one direction so that the separating member and the bearing guides can maintain regular positions, wherein, when a pressure applied by the paper due to an adhesive force between the paper and the transfer roller to the upper surface of the separating member is greater than an elastic force applied by the elastic force applying mechanism, the separating member and the bearing guides pivot by a predetermined angle thereby overcoming the elastic force.

Abstract
A paper separating apparatus of a printer includes a separating member installed to be adjacent to an exit side of the transfer roller and under a path along which the paper is discharged and fixedly coupled to a pair of bearing guides which rotatably support opposite ends of the transfer roller to be capable of pivoting by a predetermined angle together with the bearing guides, a guide roller installed at an upper surface of the separating member for guiding discharge of the paper, a pivot restricting mechanism for restricting the pivot angles of the separating member and the bearing guides, and an elastic force applying mechanism for applying an elastic force in one direction so that the separating member and the bearing guides can maintain regular positions.

8. A paper separating apparatus of a printer for preventing a paper jam from occurring when a sheet of paper which is passing between a transfer roller and a fusing roller of the printer is wound around the transfer roller, the paper separating apparatus comprising:
-
a separating member installed adjacent to one side of the transfer roller and under a path along which the paper is discharged and hinge-coupled to a pair of bearing guides which rotatably support opposite ends of the transfer roller to be operative to pivot by a predetermined angle with respect to the bearing guides;
at least one guide roller installed at an upper surface of the separating member for guiding discharge of the paper;
a pivot restricting mechanism which restricts a pivot angle of the separating member; and
an elastic force applying mechanism which applies an elastic force to the separating member in one direction so that a gap having a predetermined distance is maintained between a circumferential surface of the transfer roller and a surface of the separating member facing the transfer roller, wherein, when a pressure applied by the paper due to an adhesive force between the paper and the transfer roller to the upper surface of the separating member is greater than an elastic force applied by the elastic force applying mechanism, the separating member pivots by a predetermined angle thereby overcoming the elastic force and an upper edge portion of the separating member approaches the surface of the transfer roller so that the gap is blocked and the paper is prevented from being caught in the gap. - View Dependent Claims (9, 10, 11)
