Abstract: A paper and a continuous-form feed system for a desk-top printing electronic calculating machine comprises a platen, pin elements spaced from the platen and rotatable for driving perforated forms, and a guide support for supporting and conveying the forms towards the pin elements. A pair of guide elements disposed at the sides of the guide support guide the continuous forms laterally. A pair of locating elements, associated with the guide elements, position the forms transversly with respect to the guide support and the pin elements. A container, fixed removably to the calculating machine during the use of the forms, comprises a distributor from which the forms are conveyed toward the machine and a collector in which the forms coming from the machine are accommodated.
