Abstract

PURPOSE: To simplify the system by providing a release mechanism, an input means of a key code, a memory for unlocking code, an operation circuit, and a comparator thereof and releasing the lock when these coincide with each other and also releasing it if these coincide with each other through the operation even when they do not coincide with each other. CONSTITUTION: Unlocking codes of respective rooms are stored in a memory for releasing electronic locks. Magnetic cards in which unlocking codes are written by a magnetic card issuer provided with the same operation circuit and digital lock with the electronic lock are delivered to room users. After the card is put in the electronic lock to unlock the lock and enter the room. The key code inputted from a magnetic card reader 1 is compared with a unlocking code inputted in a comparator 3 from the memory 2 through a pass A from the memory 2. Discordant codes are added in the same way with the magnetic card issuer from the operation circuit through a pass B and then, it is compared with the key code to release the lock through a drive circuit 6 and a lock mechanism 5. In this way, a low cost and high security can be obtained.
