Abstract: A punching, reading and printing machine for document cards having a hopper holding the cards in vertical disposition, card transporting means moving the cards out of the hopper into horizontal disposition in a horizontal card path and closely spaced punching, reading and printing mechanisms operative on the cards while in the horizontal path. The punching mechanism includes a row of punches extending transversely of the card path each made active by an interposer and a leaf spring actuator for the interposer, and the printing mechanism includes a row of print hammers extending longitudinally of the card path and an electromagnet and armature for each of the print hammers. The interposer springs extend longitudinally of and over the path of card travel preceding the punches, and the armatures extend transversely of the machine for shortening the machine and rendering it more compact.
