SUPPORT DEVICE AND DATA MANAGEMENT METHOD

摘要

Provided is a support device in which a data carrier member can be disposed on an inner circumferential surface of a cylindrical member such that the data carrier member is not broken by coming into contact with a support shaft, and a shaft part for operating a anchoring means has high bending rigidity. A support device (21) for supporting a cylindrical member (6) around which is wound an elongated body (RS) has: a support shaft (213) for supporting the cylindrical member (6) that is fitted to an external surface of the support shaft (213) from an opening on one end in a longitudinal direction of the cylindrical member; an anchoring plates (217), built into the support shaft (213), for anchoring the cylindrical member (6) from an inner circumferential side of the cylindrical member (6); and an operating means having an operation shaft (214) of a smaller diameter than the support shaft (213), the operation shaft (214) protruding forward from a distal end of the support shaft (213) in order to operate the anchoring plates (217). Further, the support device (21) has a protecting member (218) which is attached to the distal end of the support shaft (214) and through which is inserted the operation shaft (214). The protecting member (218) further has a reduced-diameter section (218b) smaller in diameter than the support shaft (213).
