Patent ID: 8919763

Claim:
A feeding apparatus adapted for an office machine, the office machine defining a conveying path for transmitting sheet-like mediums therethrough, the feeding apparatus being arranged on the conveying path and comprising: a pickup roller that is arranged to contact with the mediums and rotatable to transmit each medium downstream along the conveying path; a separating roller that is arranged downstream to the pickup roller in the conveying path for receiving each medium transmitted by the pickup roller, the separating roller being rotatable to further advance each medium downstream along the conveying path; a brake roller that is arranged opposite to the separating roller for applying a braking force upstream; and a pressing structure including a pressing part that is arranged opposite to the pickup roller, a pressing arm with the brake roller and the pressing part being pivoted at two opposite ends thereof, and a first torque limiter being connected coaxially between the brake roller and the corresponding end of the pressing arm to control swing of the pressing part via the pressing arm according to a rotating direction of the brake roller, wherein when only one medium is transmitted between the separating roller and the brake roller, the brake roller rotates along with the separating roller downstream and drives the pressing structure to swing the pressing part toward the pickup roller by virtue of the first torque limiter so as to apply a normal force onto the only one medium for the convenience of the pickup roller picking the only one medium, when more than one medium are transmitted between the separating roller and the brake roller, the brake roller stops rotating along with the separating roller and stops mediums, of the more than one medium, which are not contacted with the separating roller because friction forces among the mediums are smaller than the braking force of the brake roller, the brake roller further drives the pressing structure to swing the pressing part away from the pickup roller by virtue of the first torque limiter so as to reduce the normal force between the pickup roller and the current medium being transmitted by the pickup roller and avoid more mediums from being further transmitted downstream, and wherein the pressing part is a floating tray for loading the mediums thereon.
