Abstract
A lock section is mechanically operated by a key provided with identification information to perform a locking or unlocking operation. A receiver acquires the identification information from the key. A checker determines whether the identification information acquired by the receiver matches with pre-stored registration information of the key. A limiter restricts the unlocking operation of the key when the checker determines that the identification information does not match with the registration information.
Claims10
A locking device operable with a key provided with identification information, the locking device comprising:
- a lock section, mechanically actuated by the key to perform a locking or unlocking operation;
- a receiver, which acquires the identification information from the key;
- a checker, which determines whether the identification information acquired by the receiver matches with pre-stored registration information of the key;
- and
- a limiter, which restricts the unlocking actuation of the lock section when the checker determines that the identification information does not match with the registration information, wherein:
- the lock section is formed with a hole;
- the limiter has a protrusion axially movable between a first position which is inside of the hole and a second position which is outside of the hole;
- and
- the protrusion is placed at the first position when the checker determines that the identification information does not match with the registration information.

- a receiver, which acquires the identification information from the key;
- a checker, which determines whether the identification information acquired by the receiver matches with pre-stored registration information of the key;
- and
- a limiter, which restricts the unlocking actuation of the lock section when the checker determines that the identification information does not match with the registration information,
- further comprising an adjuster connected to the lock section to adjust an entire axial length of the locking device in accordance with a length of the key, the adjuster accommodates the limiter therein.

- a receiver, which acquires the identification information from the key;
- a checker, which determines whether the identification information acquired by the receiver matches with pre-stored registration information of the key;
- and
- a limiter, which restricts the unlocking actuation of the lock section when the checker determines that the identification information does not match with the registration information,
- further comprising an actuator interlocked with the locking or unlocking operation of the lock section, wherein:
- the limiter has a protrusion movable axially between a first position which disables the actuator to move and a second position which enables the actuator to move;
- and
- the protrusion is placed at the first position when the checker determines that the identification information does not match with the registration information.
