PROBLEM TO BE SOLVED: To eliminate a point to be hard to use and a point to cause partial contact in excessively regulating tilting and oscillation of a transfer part in using even when force from a case body is truly reflected or absorbed too much. SOLUTION: An opening part 2a is formed on a portion to expose the transfer part 3 of the case body 2, and a fitting part 3c orthogonal with wall surfaces 3b provided in an opposed state on both sides in the carrier route cross direction of a head end part 3a and fitted in the opening part 2a and a connecting part 3d connected to a supporting part 2b in the case body 2 by extending from the head end part 3a and free to elastically deform are provided on the transfer part 3. Consequently, the partial contact is eliminated as the connecting part is flexibly and elastically deformed. Additionally, excessive elastic deformation by the connecting part is regulated by fitting of the opening part and the fitting part. Consequently, it is possible to certainly prevent the partial contact and to stably transfer a transfer medium linearly and curvedly by properly reflecting force from the case body without causing a problem that it is hard to transmit force to a transfer head and hard to use it.
