Abstract
Provided is a medium treating device comprising hairbrush rollers (40A and 40B) having hairs implanted on their surfaces. Between the hairbrush rollers (40A and 40B) and the reading faces of scanners (30A and 30B), there are formed clearances for allowing the passage of a medium (2). When transfer rollers (20A and 20B) transfer the medium (2) in a medium direction, the hairbrush rollers (40A and 40B) guide the medium (2) while regulating the face of the medium (2) on the side opposite to the read face.
Claims14
An image reader comprising:
- a transfer path through which a sheet medium is transferred;
- a transfer means for transferring the medium through the transfer path;
- a scanner for reading image data printed on the medium by scanning mainly in a medium-width-wise direction, perpendicular to a medium transfer direction in which the medium is transferred, and by sub-scanning in the medium transfer direction;
- and
- a bristle brush roller facing the scanner across the transfer path and having bristles implanted on a surface of the roller;
- and
- a gap exists between the bristle brush roller and a reading surface of the scanner for allowing the medium to pass through;
- wherein, when the transfer means transfers the medium in the medium transfer direction, the bristle brush roller regulates a surface opposite to a to-be-read surface of the medium in order to guide the medium.

A medium processor comprising:
- a transfer path through which a sheet medium is transferred;
- a transfer means for transferring the medium;
- and
- an evacuation path, connected to the transfer path, for evacuating the medium out of the transfer path, at least in a certain case;
- wherein a datum surface for transfer motion, providing a datum position in the medium-width-wise direction for the medium during its transfer motion, is formed at an end in the medium-width-wise direction of the transfer path, perpendicular to a transfer direction of the medium;
- wherein the transfer means includes a transfer roller positioned in the transfer path for transferring the medium, and an opposing roller placed so as to oppose to the transfer roller and biased against the transfer roller;
- wherein the opposing roller is supported in such a way that, in the pad roller, the opposite side from the datum surface for transfer motion is displace-able in the medium transfer direction;
- and
- wherein the transfer means reciprocates the medium internally by using the evacuation path for shifting the medium toward the datum surface for transfer motion.
