Abstract
After detecting an anterior end of a photosensitive material with a sensor, a controlling unit controls a release unit to release a nip of a carrying roller pair carrying the photosensitive material. The nip of the carrying roller pair is released in accordance with a length of the photosensitive material in a carrying direction thereof. It is possible to avoid applying a force of the carrying roller pair to a posterior end of the photosensitive material so that a skew-correction amount of a skew corrector is prevented from deteriorating. A skew of the photosensitive material is surely corrected relative to the carrying direction of the photosensitive material.
Claims16
A sheet carrying device for carrying a sheet along a passage, said sheet carrying device correcting a skew of said sheet relative to a carrying direction thereof while carrying said sheet, said sheet carrying device comprising:
- a skew corrector for correcting the skew of said sheet by making passage lengths different at both ends of said passage in a width direction thereof;
- carriers disposed at upstream and downstream sides of said skew corrector to carry said sheet along said passage;
- a first carrying-force changer for performing one of removal and reduction of a carrying force to be applied to said sheet by said upstream carrier;
- and
- a controller for controlling said first carrying-force changer after an anterior end of said sheet has reached said downstream carrier and a carrying force has been applied to said sheet.
