Abstract
A card reader includes a housing enclosing the operating components thereof which is provided with a card insertion slot. A baffle is movable between blocking and unblocking positions to block and unblock the card insertion slot, as desired. Located interiorly of the housing is a card carriage which reciprocates between a first limit position proximate the card insertion slot and a second limit position remote therefrom for transporting an inserted card along a path past a transducer located inside the housing proximate the second limit of travel for reading information from the card. A cam is provided on the carriage which cooperates with a cam follower associated with the baffle for camming the baffle from its card insertion slot blocking position to its card insertion slot unblocking position and vice versa, as the carriage moves toward and away from, respectively, its first limit position proximate the card insertion slot.
