Abstract
A lock apparatus includes: a control unit carrying out transmission and reception of an electronic signal between the electronic key and the control unfit so as to perform ID verification; a rotating member disposed rotatably inside a casing; a lock actuator receiving a lock release signal from the control unit so as to release a lock on the rotating member to the casing; a key insertion hole disposed to the rotating member; a slider hole going through the rotating member; a slider inserted into the slider hole and disposed such that its inner end is protruded into the key insertion hole; and a check lever supported rotatably and in which one end thereof is an operating portion activating the transmission and reception of the control unit and the other end makes contact with the outer end face of the slider. An outer end face of the slider is submerged from the external peripheral face of the rotating member when the electronic key is not inserted or inserted incompletely, and the slider is pushed by an insertion portion of the electrical key and slid outward when the electronic key is inserted normally, so that the outer end face makes flush with the external peripheral face of the rotating member. When the rotating member is rotated by the, electronic key, the other end of the check lever is moved from the outer end face of the slider to the external peripheral face of the rotating member.
