PROBLEM TO BE SOLVED: To provide a simple and safe electric lock device at a relatively low cost. SOLUTION: An image of a two-dimensional code surface of a key 2 is picked up by an image inputting part 4 in a lock device body 3 and is converted to a digital signal in an image processing part 5, and key data is produced based on conversion data of a storage holding part 9. The key data is compared with collation data in a comparing part 7, and, when they match to each other, a lock of an electromagnetic lock part 8 is released to open a door. |
