A replacement blade supplying mechanism (51) includes a detection portion (75) which detects whether or not there is a cutting blade (21) in a layer below an uppermost cutting blade (21d) through a through hole (21b) of the uppermost cutting blade (21d) when the uppermost cutting blade (21d) is extruded by a lever portion (54), and when the detection portion (75) detects that there is no cutting blade (21) in a layer below the uppermost cutting blade (21d), the detection portion stops the transport of the cutting blade (21) by a cutting blade transport mechanism (26). |
