摘要： A sheet convey apparatus includes a main feed roller, retard roller, torque limiter, retard roller guide, a pair of bearings, and a spring. The main feed roller rotates in a predetermined direction in contact with one surface of a paper sheet, to give to the sheet a force to convey the sheet in a sheet convey direction. The retard roller is arranged to oppose the main feed roller and gives to the sheet with which the retard roller is in contact a force to convey the sheet in a direction opposite to the sheet convey direction. The torque limiter limits a torque of the retard roller and rotates the retard roller in the sheet convey direction when the torque exceeds a predetermined limit. The retard roller guide includes at least a surface inclined with respect to a plane connecting central axes of the main feed roller and retard roller at an angle in a range of 0° (exclusive) to 90° (inclusive). The inclined surface is located in the vicinity of the central axis of the retard roller. The pair of bearings rotatably support a rotating shaft of the retard roller. The spring urges a bearing of the retard roller against the inclined surface of the retard roller guide to generate a component toward the main feed roller which is perpendicular to a reaction force from the inclined surface.

摘要： In a double-sided document transport device having a document reverse mechanism for suppressing the occurrence of jam and deterioration of read image, after a document is transported to a reading position, it is transported to the reading position again to read a rear side thereof through a reverse path. The device has discharge rollers disposed on an upper side and pinch rollers disposed on a lower side. The discharge rollers discharge a document as well as guides it to the reverse path by reversing it while claming the rear end thereof. The pinch rollers are fixed, and the discharge rollers are separated therefrom approximately upward about a rotation shaft of a transport unit. For this purpose, the discharge rollers are pressed against the pinch rollers and separated therefrom by a cancel lever. A drive system has two transmission routes one of which is reversed through a torque limiter and the other is reversed through an electromagnetic clutch.
