Abstract
According to one embodiment, an image forming apparatus includes an accommodation unit and at least one driving roller. The accommodation unit accommodates a paper sheet therein. The at least one driving roller is disposed contactably with the paper sheet. A rotation direction of the at least one driving roller with respect to the paper sheet at a contact part between the paper sheet and the roller intersects a carrying direction of the paper sheet.
Claims16
An image forming apparatus comprising:
- an accommodation unit configured to accommodate a paper sheet therein;
- at least one driving roller configured to contact the paper sheet, wherein rotation of the driving roller while the driving roller is in contact with the paper sheet propels the paper sheet along a plane tangential to a contact position and coplanar with a carrying direction of the paper sheet;
- a separation mechanism that moves the at least one driving roller out of the contact position to a separation position where the at least one driving roller is separated from the paper sheet;
- and
- a pickup roller that is disposed on a downstream side of the at least one driving roller in the carrying direction,
- wherein the at least one driving roller includes a first roller and a second roller, and the first roller and the second roller are disposed so that rotation shafts of the first roller and the second roller are separated from each other and are positioned such that a first vector normal to a curved surface of the first roller and a second vector normal to a curved surface of the second roller intersect on a downstream side of the rotation shafts with respect to the carrying direction.

An image forming apparatus comprising:
- an accommodation unit configured to accommodate a paper sheet therein;
- and
- at least one driving roller configured to be disposed contactably with the paper sheet and whose rotation shaft intersects a paper width direction which is substantially orthogonal to a carrying direction of the paper sheet;
- a separation mechanism that moves the at least one driving roller between a contact position where the at least one driving roller comes into contact with the paper sheet and a separation position where the at least one driving roller is separated from the paper sheet;
- and
- a pickup roller that is disposed on a downstream side of the at least one driving roller in the carrying direction.
3 more elements
A paper feeding method comprising:
- bending a paper sheet by moving the paper sheet accommodated in an accommodation unit in a direction intersecting a carrying direction of the paper sheet with at least one driving roller;
- and
- carrying the paper sheet in the carrying direction;
- moving the at least one driving roller between a contact position where the at least one driving roller comes into contact with the paper sheet and a separation position where the at least one driving roller is separated from the paper sheet, wherein
- a pickup roller is disposed on a downstream side of the at least one driving roller in the carrying direction.
