Claim Text:
1. A conveying apparatus comprising: a first pair of rollers which has a drive roller and a pinch roller, and conveys a sheet in a conveying direction; an arm which supports the drive roller and which swings coaxially with a rotating shaft rotated by drive from a drive source; a second pair of rollers which is positioned downstream of the first pair of rollers in the conveying direction and which conveys the sheet conveyed by the first pair of rollers; and a mechanism which is adapted to reduce a force for sandwiching the sheet by the first pair of rollers, wherein the mechanism includes a transmitting unit which transmits the rotation of the rotating shaft to the drive roller so as to rotate the drive roller such that the sheet is conveyed in the conveying direction in the case where the rotating shaft rotates in the same direction as the swing direction of the arm at the time the arm swings to press the drive roller against the pinch roller, and a clutch that cuts off a rotational force transmitted from the drive source to the rotating shaft, and wherein after a leading edge of the sheet conveyed by the first pair of rollers is stopped by the second pair of rollers, the second pair of rollers starts conveying the sheet, and the mechanism works while the sheet is conveyed by the second pair of rollers.
