Abstract
A cutting apparatus includes a blade changing apparatus. The blade changing apparatus includes a blade mounting and removal portion, which in turn includes: a holding portion that removably holds a circular base of a cutting blade; a moving support portion that supports the holding portion and moves the holding portion to a removal and mounting position at which an insertion hole in the blade faces a boss of a blade mount; and a coupling mechanism that couples the holding portion with the moving support portion such that the holding portion is freely tiltable with respect to the moving support portion. The coupling mechanism includes a plurality of elastic member pairs, each pair, while tensioning the holding portion in opposite directions, fixing the holding portion to the moving support portion. Forces acting from the elastic member pairs balance each other to thereby support the holding portion tiltably and aerially.
