摘要： A stack of record carriers in the form of rectangular-shaped cards supported in a vertical upright position are advanced sequentially in a business machine by a sheet feeding mechanism. The forward end of the leading card is pressed against a resilient stop at a feeding position, and the leading card is separated from the remainder of the stack by retracting means driving the card rearwardly to withdraw the forward end of the leading card from the resilient stop. In timed relation with the operation of the retracting means, a feed roller is brought into engagement with the leading card to drive the card forwardly past the resilient stop. The timed relation between the operation of the retracting means and the operation of the feed roller is determined by camming means including a plurality of different cams which are selectively operable to accommodate cards of different sizes.
