Tumbler type lock apparatus |
摘要 |
A tumbler-type lock apparatus for use with a tumbler-type card key having a code pattern region including an array of holes and non-hole portions that expresses a key code of the tumbler-type card key. The tumbler-type lock apparatus includes a slider case and a slider movable relative to the slider case when the tumbler-type card key is inserted into the tumbler-type lock apparatus. Tumblers extending in the slider case and slider each correspond to one of the holes or non-hole portions. Springs bias the tumblers towards the slider. The tumbler-type lock apparatus verifies the tumbler-type card key when the tumblers are engaged with the slider case and slider during insertion of the tumbler-type card key. The slider includes accommodation portions. A distal end of the tumbler that has passed through the corresponding hole of the tumbler-type card key is accommodated in the corresponding accommodation portion.
