Abstract
PURPOSE:To secure the use of the abbreviated number through and optional telephone incorporating the reading unit, by memorizing previously and magnetically the necessary telephone number into the portable magnetic memory card and then reading out the memorized number through the telephone when necessary. CONSTITUTION:Additional unit 3 is connected to telephone 2, and the magnetic memory card is inserted into unit 3. And when the abbreviated dial writing identification control signal is delivered through telephone 2, writing circuit 6 and selection circuit 8 are started via control circuit 5. Then the writing telephone number is delivered from telephone 2 and then converted into the writing signal through code converting circuit 10 to be written into the card via circuit 6 for memorization. When the talking is given to the outside via the card, the card is inserted into unit 3. Then reading circuit 7 and circuit 8 are operated via circuit 5 and by the abbreviated dial oscillation identification control signal sent from telephone 2. The number memorized into the card is read out through circuit 7 and then converted into the dial signal via circuit 10 to be sent to telephone circuit 1. In this way, the telephone number necessary for an individual is memorized previously into the card, thus reducing the wrong calls.
