Abstract

PURPOSE: To incorporate locking and unlocking managements of a key lock in a refrigerator itself by unlocking an electronic key according to a signal from a comparator for comparing an input unit including ten keys for inputting data with a code signal stored in a memory. CONSTITUTION: A menu screen 201 is displayed by operating a start key 12 of an operating unit 3, and a code number is directly input by ten keys 15. Input numeric value data is compared with a code number already stored in a memory 7. In the case of coincidence, an unlocking signal is output to an electronic lock 11 provided at a door of the refrigerator. Meanwhile, if the input code number is different from that stored in the memory 7, number of times of its inputs is counted by a counter, and if the number of the counts is judged to be larger than a set value, its operation is finished to inhibit an illegal unlocking.
