<P>PROBLEM TO BE SOLVED: To provide a spool holder which suppresses vibration of a spool in a region where the rotation speed of the spool is high. <P>SOLUTION: The spool holder has a collet 3 which is inserted inside the spool 2 and inner peripheries of both ends of which have a taper shape, a rotary shaft 5 which rotates the spool, a pair of squeezers 4a, 4b which rotate integrally with the rotary shaft, have a surface 4e slidable with the taper shape of the collet and can be displaced in an axial direction, a positioning pin 11 which is installed inside the rotary shaft and can project outside in a radial direction, a cylindrical locking tool 7 which is attached to the rotary shaft so as to displace one squeezer out of a pair of squeezers toward another squeezer and which positions the one squeezer by fitting to the projecting positioning pin, a spring 14 which energizes the other squeezer toward the one squeezer, and a release pin 9 which is provided inside the locking tool and pushes back the positioning pin in the rotary shaft to release fixing of the locking tool. <P>COPYRIGHT: (C)2012,JPO&INPIT |
