Patent ID: 7748693

Claim:
A sheet carrying device comprising: a paper feeding roller for sending out a sheet to a carrying path one by one from a sheet mounting tray; a roller driving device for rotating the paper feeding roller; and a control section for controlling the roller driving device to rotate the paper feeding roller, the sheet carrying device including a slip detecting device for detecting whether or not a slip of the paper feeding roller occurs in an amount equal to or more than a predetermined amount when the sheet is carried, the control section controlling the roller driving device so as to perform a slip-settling operation which decreases a start-up acceleration of the paper feeding roller when the slip detecting device detects that a slip of the paper feeding roller occurs in an amount equal to or more than the predetermined amount, the start-up acceleration being an acceleration from a time when the paper feeding roller starts to rotate to a time when the paper feeding roller reaches a predetermined speed, and wherein the control section counts up a total number of sheets carried by the paper feeding roller, and the control section controls the roller driving device so that the slip-settling operation is performed when the total number of sheets carried is not less than a predetermined number and that the slip-settling operation is not performed when the total number of sheets carried is less than the predetermined number.
