PURPOSE: To provide a safe-deposit box control system which enables reduction of multifunctioning due to accidents of transmission cables and parts through a remote- concentrated control.

CONSTITUTION: When a push is given to number corresponding to the intended locker on push keys 1, the output of the push keys is converted to a binary digit according to digit and memorized by a shift register. Then, via a decoder/driver, the selected number is indicated. On the other hand, attached by r-out of-n code or a code for parity check according to digit, the numeral stored in the shift register is sent to a transmission cable through a linedriver. In a safe-deposit box, a decoder receives and decode these signals including check bits so as to connect a solenoid coil for unlocking lockers composing the safe-deposit box to the power source via a main key 3. Under such a condition, when the main key is pushed, current is fed to the solenoid coil to unlock the corresponding locker
