Abstract
A paper feeding device of an inkjet printer includes a motor generating a drive force, a pickup drive shaft rotated by the motor, a pivoting link housing disposed on the pickup drive shaft, a pickup roller connected to the ling housing, and a clutch enlinking the pickup drive shaft and the link housing enabling the link housing to pivot by a predetermined angle by rotation of the pickup drive shaft.
Claims15
A paper feeding device of an inkjet printer comprising:
- a motor generating a drive force;
- a pickup drive shaft rotated by the motor;
- a pivoting link housing having first and second outer surfaces facing in opposite directions, the link housing being pivotably disposed on the pickup drive shaft;
- a pickup roller connected to the link housing;
- and
- a clutch enlinking the pickup drive shaft and the link housing enabling the link housing to pivot by a predetermined angle by rotation of the pickup drive shaft in a first direction of the motor, the clutch comprising first and second portions respectively in contact with the first and second outer surfaces of the link housing so that the link housing is between the first and second portions.

- a motor generating a drive force;
- a pickup drive shaft rotated by the motor;
- a pivoting link housing pivotably disposed on the pickup drive shaft;
- a pickup roller connected to the link housing;
- and
- a clutch enlinking the pickup drive shaft and the link housing enabling the link housing to pivot by a predetermined angle by rotation of the pickup drive shaft, wherein the link housing comprises:
- a pickup drive gear to drive the pickup roller;

A paper feeding device, comprising:
- a rotatable pickup drive shaft;
- a pivoting link housing, driven in first and second directions by the pickup drive shaft;
- a pickup roller connected to the link housing and coupled to the pickup drive shaft;
- and
- a clutch which links the link housing and the pickup drive shaft,
- wherein
- when the pickup drive shaft rotates in a first direction and the pickup roller comes in contact with paper, the link housing is prevented from pivoting, a slip occurs between the link housing and portions of the rotating pickup drive shaft on opposite sides of the link housing due to the clutch, and the pickup drive shaft forces the pickup roller to engage, and
- when the pickup drive shaft rotates in the second direction, frictional contact between the link housing and the pickup drive shaft causes the link housing to pivot a second predetermined angle about the pickup drive shaft such that the pickup roller is removed from contact with the paper.

- a rotatable pickup drive shaft;
- a pivoting link housing, driven in first and second directions by the pickup drive shaft;
- and
- a pickup roller connected to the link housing and coupled to the pickup drive shaft;
- wherein
- when pickup drive shaft rotates in a first direction and the pickup roller comes in contact with paper, the link housing is prevented from pivoting, a slip occurs between the link housing and the rotating pickup drive shaft, and the pickup drive shaft forces the pickup roller to engage, and
- when the pickup drive shaft rotates in the second direction, frictional contact between the link housing and the pickup drive shaft causes the link housing to pivot a second predetermined angle about the pickup drive shaft such that the pickup roller is removed from contact with the paper, wherein the clutch comprises:
- a fixing member on the pickup drive shaft in contact with a first outer surface of the link housing;
- and
- a press on the pickup drive shaft pressing the link housing towards the fixing member.

A paper feeding device of an inkjet printer, comprising:
- a motor generating a drive force;
- a bi-directionally rotatable pickup drive shaft coupled to the motor;
- a pivoting link housing, driven in a first direction by the pickup drive shaft;
- a pickup roller connected to the link housing and coupled to the pickup drive shaft;
- wherein
- when the pickup drive shaft rotates in the first direction and the pickup roller comes in contact with paper, the link housing is prevented from pivoting, a slip occurs between the link housing and the rotating pickup drive shaft, and the pickup drive shaft forces the pickup roller to engage, the pickup drive shaft being prevented from moving in a second direction, opposite the first direction, and
- when the pickup drive shaft rotates in the second direction, frictional contact between the link housing and the pickup drive shaft causes the link housing to pivot a second predetermined angle about the pickup drive shaft such that the pickup roller is removed from contact with the paper;
- and
- an abrasion prevention member on one side of the outer surface of the link housing and in contact with the press.
