An office machine includes a pair of input feeders and an output feeder for processing flat articles, such as for automatically labeling envelopes. One input feeder for feeding the blank envelopes includes an elongated member formed with a rounded lower end facing the entrance to the feeder, and a roller disposed under the elongated member in alignment with its rounded lower end. The elongated member is pivotably mounted such that its rounded lower end is urged against the roller, the surface friction of the roller being greater than that of the rounded lower end to effect the feed of one envelope at a time between them. The output feeder includes a conveyor platform having a plurality of hinged sections permitting the platform to be disposed in either an extended operative position wherein the hinged sections are extended for conveying the labeled envelopes, or in a folded non-operative position wherein the hinged sections are folded to conform to the configuration of the machine casing. The second input feeder is for a carrier-strip carrying the labels to be applied to the blank envelopes, this feeder including a retractable support for supporting same in a projected position external of the machine casing when the conveyor platform is in its extended operative position, or in a retracted position within the machine casing when the conveyor platform is in its folded non-operative position.
