Abstract
An apparatus for transporting sheets into a fixed image reading position has a drive roller and a pad. The pad has a lower layer made of a flexible material and an upper layer provided on the lower layer and made of rigid material in the form of film with a kinetic friction coefficient of 0.2 or less. The is biased to the drive roller so that the upper layer contacts a peripheral surface of the drive roller to form a nipping region between the drive roller and the pad by a compressive deformation of the flexible lower layer of the pad.
Claims7
An apparatus for transporting sheets into a fixed image reading position, comprising:
- a drive roller;
- and
- a pad comprising a lower layer made of a flexible material and an upper layer disposed on the lower layer and made of a rigid material with a kinetic friction coefficient of 0.2 or less, the pad being biased to the drive roller so that only the upper layer contacts a peripheral surface of the drive roller to form a nipping region between the drive roller and the pad by a compressive deformation of the flexible lower layer of the pad,
- wherein the pad is configured within the apparatus so that sheets traveling between the driver roller and the pad do not come in contact with any flexible material that has a kinetic friction coefficient higher than the rigid material of the upper layer.
An apparatus for transporting sheets into a fixed image reading position, comprising:
- a drive roller;
- a rigid backup portion comprising a top surface facing the driver roller;
- a lower layer made of a flexible material and covering the entire top surface of the rigid backup portion;
- an upper layer disposed on the lower layer and made of a rigid material with a kinetic friction coefficient of 0.2 or less;
- and
- a spring which biases the rigid backup portion to the drive roller so that only the upper layer contacts a peripheral surface of the drive roller to form a nipping region between the drive roller and the upper layer by a compressive deformation of the flexible lower layer of the pad.
