Kind Code:
A
Abstract:
The selection and retrieval of information cards is facilitated by tilting a cassette containing a number of cards forwardly to a position in which the cards are inclined, with their coded edges facing downwardly. Selector bars cooperate with notches in the coded edges of the cards such that only the card whose notches correspond to selector bars that are in their ON position can be partly pulled out of the cassette. Selector magnets are then brought against the coded edges of the cards and are moved away to partly pull out of the cassette only the card which is not prevented from moving by the selector bars. Since the selected card is moving obliquely downwardly, its frictional drag against the other cards in the cassette is very low. The result is that the cassette can contain a greater number of cards than in the prior art, the selection magnets can have lower strength, and reliability is enhanced.
