Abstract
An object of the present invention consists in providing a new spool case in which the stored spool can be held without contacting with it by hand, engaging or disengaging of the spool in respect to the bonding device can be carried out without having any relation with a length of the holder or presence or non-presence of an engaging means, a reliability in holding the spool is high and a spool held state can be easily maintained. In addition, solving means of the present invention can be handled such that the spool is held by the engaging pieces 7 arranged at the base 3 and the spool is not directly contacted with hand. The spool held state is maintained by the resilient engaging force of each of the engaging pieces 7 and this is not released so long as each of these engaging pieces 7 is not resiliently deformed and is not released from the flange. The held state causes each of the engaging pieces 7 to be engaged with the outer circumferential edge of the flange, wherein no interference occurs against the wire wound around the spool barrel section section or inside the barrel section.
