Patent ID: 7909320

Claim:
A feeding apparatus comprising: a feeding roller for feeding a sheet in a sheet feeding direction; a separation roller for conveying the sheet in a reverse direction against the sheet feeding direction based on a rotational force transmitted through a torque limiter, the separation roller being opposed to the feeding roller; a transmission mechanism for transmitting the rotational force to the feeding roller; a first sensor for detecting existence of the sheet, the first sensor being arranged downstream against the feeding roller in a sheet conveyance direction; a temperature detector for detecting ambient temperature; and a controller which determines a first predetermined time interval, which is a time interval from a reference time set after starting feeding the sheet with the feeding roller to a moment when the first predetermined time interval has elapsed, based on detected information from the temperature detector, wherein the controller temporarily stops transmitting the rotational force to the separation roller so that the separation roller rotates in the sheet feeding direction driven by a rotation of the feeding roller in case the first sensor does not detect the sheet within the first predetermined time interval, and re-transmits the rotational force to the separation roller.
