<p>PURPOSE:To see that door lock can be released even in the case that the battery being the power source of a transmitter consumes and that power runs out, in an object where the lock of the door can be released by the midair propagation signal issued from a transmitter. CONSTITUTION:When a ignition key 6 is inserted in the rotor 13 of a key cylinder, a shutter opens, which operates a shutter switch 15. In this condition, the rotor 13 is rotated by a specified pattern in forward direction or reverse direction from the neutral position by the ignition key 6. This rotation pattern is deciphered by a rotor rotation pattern judging circuit 18, and in case that it is a preset pattern, the lock of the door by the lock mechanism is released by operating an electric operation mechanism 2.</p> |
