Abstract
A burglarproof system for automotive vehicle which precludes a burglar from improperly starting the engine of an automotive vehicle using a duplicate key or short-circuiting a starter circuit. A magnetic card having a plurality of permanent magnets buried wherein and representing a predetermined password, and a card reader reading the poles and arrangement of the permanent magnets appearing on the upper surface of the magnetic card. One embodiment reads the password in a static reading mode. A second embodiment reads the password during movement of the magnetic card. A password comparator of the burglarproof system compares the password of the magnetic card with the predetermined password. A coincidence signal from the comparator establishes an electric circuit required for starting the engine of the automotive vehicle. A terminal cover made of insulator and covering the starter switch terminal and an electric wire from an electric battery are screwed to an end surface of a pull switch having a starter switch terminal and a battery connecting terminal both extending from the surface. A second starter switch terminal passes through the terminal cover. A double-core electric wire having a sheath grounded to the body of the automotive vehicle passes into the terminal cover. One end of one core is connected with the starter switch terminal and one end of the other core is connected with the second starter switch terminal. The other end of both cores is connected with a switch of the burglarproof system.
