<p>PURPOSE: To enhance security by enhancing a covert entry detection system of an electronic lock. CONSTITUTION: A dial 14 is connected to a generator 29 and a retractor-operated cam 30. The generator 19 is driven by the dial 14 and a shaft 20 and produces electrical pulses, and supplies a power source 36 that charges an external capacitor, and voltage is supplied to a microprocessor 44. The microprocessor 44 is provided with power by charge in a power control part 36, after dialing is stopped. The microprocessor 44 supplies an output to a display device 18 via an LCD drive device. The display device 18 can display a character/numeral combination signal 13 and an arrow mark 15. A lightning mark 17 for displaying errors, a key sign 23 and the like are used to display selection of combination change mode, and characters are used to provide a function and state of a security system.</p> |
