At this time, the second elastic member 322 and the sixth elastic member 332 are in a compressed state, and the first elastic member 231 and the fifth elastic member 241 are in a compressed state. The cover plate feeding mechanism places the cover plate 201 between the first positioning member 235 and the second positioning member 245 along the third direction, and abuts against the support member 14.
