Abstract: A hand-fed data-card reader compatible with cards of different widths and having a selectively actuable perforator for conveying cards past a reader head and for selectively cancelling desired cards via the perforation thereof. Cards are conveyed via a belt/pulley drive train that is operably coupled to a spiked perforator that engages each card at a preset one of two pressures so as to selectively convey the card with or without embossing the surface in a chadless fashion and whereby cancellation is achieved. Data media of differing widths are accommodated via an adjustable, lower, spring loaded guide assembly.

Abstract: A cordless graphics input device system for use with a computer. The device comprises an infrared emitting module useable on any surface adjacent a detector having a pair of patterned concave sensors. Coordinate information is determined via a detector contained microprocessor relative to the sensed analog position data.
