Cutter cassette and cutting device

摘要

A cutter cassette mechanism includes a holding mechanism for holding a cutter blade in a completely inserted state and an extending mechanism for protruding the cutter blade from the case holder. The cutting blade is held in the holding mechanism when not used, and is promptly ejected by the extending mechanism when used. A cutting device mounted on a rail and a portable hand-operated cutter are also provided. Preferably, the cutting device includes a driving mechanism for shifting the cutting blade in the cutter cassette into an operative state in synchronization with the operation of pushing the cutter cassette.
