PROBLEM TO BE SOLVED: To provide a duplicate key duplicator capable of remarkably reducing an error between a made copy key and an original key more than a conventional duplicate key duplicator, when making the copy key from a copy key, since an error between the original key and a first time copy key is not accumulated in a second time copy key, when further making a copy key of its copy key, by making the copy key of the original key having a form causing a deviation between the center line between sandwiching surfaces of a key vice sandwiching a key and the center line in the thickness direction of a side end part of the sandwiched key. SOLUTION: The contact end of a guide 202 for a master key is constituted in a pointed head shape having the apex 202P. The error between this original key and the first time copy key 20b becomes maximum in an upper end part in its thickness direction. The apex 202P contacts with a part smaller in the error than the upper end part. COPYRIGHT: (C)2007,JPO&INPIT
