摘要： PURPOSE: To transmit electronic signals from a key as well when the key is inserted completely in a cylinder lock as during the insertion by installing a means to admit an inductive transmission of electric signals between the key and cylinder lock. CONSTITUTION: Surrounding a lock cylinder 12 having a slit 13 of a cylinder lock, a transmission yoke 14 is arranged consisting of legs 14.1 and 14.2 having reading legs 15.1 and 15.2 and a central part 14.3 where a cylinder lock coil 16 connected with a reading electronic apparatus to evaluate the induction signal is wound round. A key includes a key coil 21 fitted with a core 22, and the coil 21 is installed plumb to the inserting direction A of the key 2, and a signal transmitter is installed to transmit electric signals to the key coil 21. The electric signals working on the coil 21 generate a magnetic field in the common core of the coils 16 and 21 and induce the corresponding signal in the coil 16.

摘要： PURPOSE: To prevent imitation by providing a zone for a side surface code, in addition to a depth code on a tumbler pin, making a diameter correspond to an additional code and providing a dent to correspond to the pin and a lateral side surface to correspond to a encoded diameter on a key. CONSTITUTION: A dent with respect to a control pin K is provided on the narrow side surface of a key S, and a dent with respect a tumbler pin Z is provided on a flat surface. Additionally, a stage of pin width, that is B0 -B2 , a stage of pin length, that is T0 -T3 and two installation surfaces O1 and O2 of either of an end part surface forming a standard surface against scanning of depth and an offset surface are formed on the control pin K. Thereafter, an offset produced as a result of side surface code is used as additional binary codes O1 , O2 , so as to conceal a code having a possibility of 24 with single piece of the pin K. Consequently, it is possible to improve maintenance with respect imitation of forgery of the key S.
