Abstract:
1. A sheet carrying device comprising: a paper feeding roller sending out a sheet on a sheet mounting tray into a carrying path one sheet at a time; a roller driving device rotating the paper feeding roller; a control section controlling a rotational drive of the paper feeding roller which rotational drive is carried out by the roller driving device; and a carrying delay detecting section detecting delay in sheet carrying carried out by the paper feeding roller, the control section controlling the roller driving device, in a case where the delay in the sheet carrying is detected by the carrying delay detecting section, so as to carry out a slip settling operation in which (i) the paper feeding roller once stops and then restarts rotating and (ii) a start-up acceleration of the paper feeding roller from restart of rotation to arrival at a predetermined speed becomes lower than a first start-up acceleration from start of rotation of the paper feeding roller to arrival at the predetermined speed in a case where there is no delay in the sheet carrying, wherein: in a case where the delay in the sheet carrying is not resolved by the slip settling operation, the control section retries the slip settling operation and sets the start-up acceleration in the slip settling operation so that, as the number of times of the slip settling operations increases, the start-up acceleration becomes lower.
