<p>PROBLEM TO BE SOLVED: To provide a password leakage countermeasure electronic lock that makes it hard to observe an input process for a password and disables the password to be easily confirmed in spite of an observation or video recording.SOLUTION: A password leakage countermeasure electronic lock includes: a number display plate (40) which displays numbers so that the numbers are observed from above in front of a front see-through window (30) toward obliquely below; a dial button (50) which is rotated to generate a rotation signal or pushed to generate a push signal; a locking mechanism (70) which makes a dead bolt (71) acts to lock or unlock a door (15); and a control device (60) which performs control to receive the transferred rotation signal of the dial button, and increases or decreases and displays the number of the number display plate each time an angle of rotation changes by a certain angle, to recognize the number of the number display plate displayed during transfer of a push signal as an input number of a password, and to unlock the door by a locking mechanism when input numbers match the password which is input in order and preset.</p> |
