Abstract

A card securing mechanism for retaining a card 90 in a reader includes a cam 66 pivotally mounted to a guide arm 20 associated with a side edge 94 of a card 90. The cam 66 is mounted at the entrance 34 of a card-receiving channel 30 proximate and beside a push button 36 slidably mounted along the guide arm 20 such that a first cam portion 74 can be rotated into and out of the channel 30. The first cam portion 74 has a notch 76 dimensioned to receive and secure a corner 96 of a card 90 when the card 90 is fully within a reader and the first portion 74 is rotated into the channel 30. A second cam portion 78 is adapted to be engaged by an actuator activated by the card ejection mechanism 50. The cam 66 is pivoted to a card engaging position upon insertion of a card 90 into the card reader. Upon activating the card ejection mechanism, the actuator permits cam 66 to be pivoted from a card engaging position to a card releasing position as the card 90 is urged outwardly of the channel 30 by a card ejection mechanism 50.
