Abstract
A cutter cassette includes a cutter case for holding a cutting blade slidably in a case holder. The cutter cassette further includes a holding mechanism for holding the cutter case in a completely inserted state and an extending mechanism for protruding the cutter case 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.
Claims17
A cutter cassette mechanism including a cutter cassette movably holding a cutting blade therein, comprising:
- a holding mechanism for holding the cutting blade therein in a completely inserted state;
- an extending mechanism for extending the cutting blade outwardly;
- and
- an opening on the outside surface for operating the extending mechanism by using an external driving mechanism,
- wherein the extending mechanism extends the cutting blade in synchronization with the external driving mechanism, the extending mechanism including a first rack formed on the side of a case holder and a second rack formed on the side of a cutter case, the first rack being formed in parallel with the opening formed on the side of the case holder, and the second rack being formed in parallel with the first rack and closer to the center of the cutting blade than the first rack so as to face the opening.
A cutter cassette mechanism including a cutter cassette singly holding the cutting blade therein in a completely inserted state, comprising:
- a holding mechanism for holding the cutting blade therein in a completely inserted state;
- an extending mechanism for extending the cutting blade outwardly;
- and
- an opening on the outside surface for operating the extending mechanism by using an external driving mechanism,
- wherein the extending mechanism extends the cutting blade in synchronization with the external driving mechanism, the extending mechanism including a first rack formed on the side of a case holder and a second rack formed on the side of a cutter case, the first rack being formed in parallel with the opening formed on the side of the case holder, and the second rack being formed in parallel with the first rack and closer to the center of the cutting blade than the first rack so as to face the opening.
A cutter cassette mechanism including a cutter cassette comprising:
- a cutter case for supporting a cutting blade;
- a case holder for movably housing the cutter case therein;
- a holding mechanism for holding the cutter case in the case holder in a completely inserted state;
- an extending mechanism for extending the cutter case out from the case holder so as to project the cutting blade from the case holder;
- and
- an opening on the outside surface for operating the extending mechanism by using an external driving mechanism,
- wherein the extending mechanism includes a first rack formed on the side of the case holder and a second rack formed on the side of the cutter case, the first rack being formed in parallel with the opening formed on the side of the case holder, and the second rack being formed in parallel with the first rack and closer to the center of the cutting blade than the first rack so as to face the opening.
