Abstract
A digital doorlock having an ultra capacitor is used as an emergency power. The digital doorlock includes a power source for supplying an ordinary power; a key recognition means for receiving a key required for opening a doorlock from outside; a doorlock opening/closing means for opening/closing the doorlock by comparing an input key with a key stored therein; an emergency power generating means for generating an emergency power and converting the generated power suitably for charging capacitors; and a capacitor unit provided with capacitors to store the electric energy applied from the emergency power generating means into the capacitors and supplying the energy stored in the capacitors to the doorlock opening/closing means in case the power supply is not able to supply power. This doorlock apparatus has a simplified configuration since a separate emergency opening/closing device for preparation against a complete consumption of the battery is not used.
