Claim 1

A data input device for use in an IC key lock system in which the lock of a locking system is released by inserting an IC key into a reader/writer of the locking system, comprising: a data input unit for generating data to be preset in said locking system; an IC key type of connector which is connected to said data input unit and serves as an interface like said IC key for said reader/writer and through which the data is supplied from said data input unit to said reader/writer; and a lock control unit, provided in said locking system, for receiving the data supplied from said data input unit through said reader/writer when said IC key type of connector is inserted into said reader/writer and storing the received data, whereby the data which is preset in the locking system is input into said locking system, said lock control unit including access means for accessing a member inserted in said locking device just when the member is inserted into said locking device, to inquire about whether the member is an IC key or an IC-key type connector, and request means for requesting said data input unit to transmit the data into said lock control unit when the inserted member is judged to be the IC-key type connector.
