Title: Sheet feeding device and image processing device
Inventor: KIMIZUKA EIICHIRO
IPC: B65H3/06
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of noise by constituting the surface shape of a roller member in such a way as to change in a rotating circumferential direction, thereby making stick-slip state unstable between a sheet and a pressing member so as to change with time the fixed state of the fixed end of the sheet playing the role of a chord. SOLUTION: A roller member 20 is provided with a large number of semispherical recessed parts on the peripheral surface so that its surface shape changes in the rotating circumferential direction. In case of a part with the recessed part of the roller member 20 coming in contact with a sheet S, load per unit area is reduced in comparison to the case of a part without a recessed part coming in contact with the sheet S. Accordingly, when the sheet S is fed by a pair of carrier rollers 2, load at a nip part between the roller member 20 and a separating pad 18 changes with time, and a stick-slip state becomes unstable between the sheet S and the separating pad 18, that is, since the sheet S plays a role of a chord, the fixed state of the fixed end of the chord changes with time so as to suppress the generation of noise.
