In a record card machine cards are conveyed one-by-one to a first set of rollers E 1 , E 2 , either from an associated stack 11, gripped between fixed bearing plate 12 and movable pressing member 13, 38, or from a second set of rollers A 1 , A 2 . Cards are separated from stack 11 by a driving member 15 adapted to act by adhesion through apertures 30, Fig. 4, in the bearing plate, and conveyed through throat 14. A floating flap 41 in the form of a flexible plate, fixed at 42 and free at the end near throat 14, arranged between bearing plate 12 and stack 11 provides a transit passage between the flap and the bearing plate in which a card advanced by the rollers A 1 , A 2 may be forwarded to throat 14 by member 15, Fig. 6. Flap 41 is apertured at 48 to permit member 15 to reach the stack. Pile tables and supports.-The cards in stack 11 are supported on edge on base-plate 10 and pressed against member 12 by presser 38. Separators; dropping roller feeds.-The driving member may be a driven friction roller 15 adapted to be intermittently oscillated on arm 19 about pivot 21 either to engage the first card in stock 11 through apertures 30 and 48, flap 41 being positioned as shown in Fig. 4, or to engage a card from rollers A 1 , A 2 through apertures 30 only, flap 41 then being positioned as shown in Fig. 6 to prevent feed from stack 11. Roller 15 is intermittently actuated by pulses from a generator supplied to electromagnet 25. Alternative feed control.-Photo-electric card detector PH provides a signal when a card is approaching rollers A 1 , A 2 , which signal is sent to circuits controlling the energization of magnet 25 to cause roller 15 to be brought into the operative position when the card engaged in the transit passage comes level with apertures in the bearing plate. Sheet guides.-The end of plate 41 adjacent rollers A 1 , A 2 is curved to guide cards into the transit passage.
