Abstract
A cutting apparatus which avoids exposing a fixed blade mounted in a lid portion even when the lid portion is opened. A fixed blade 40 is arranged so that a blade surface 40b faces the upstream side in the direction of transport of a printed medium 1. A cover 48 is slidably mounted on the fixed blade 40, is configured to cover a cutting edge line 40a of the fixed blade 40 from the side of the blade surface 40b when a lid portion 13 is released, and may be slid toward a root of the fixed blade 40 to expose the cutting edge line 40a of the fixed blade 40 when the lid portion 13 is closed.
Claims4
A cutting apparatus for a printer wherein
- the printer comprises a casing,
- a lid over the open upper part of the casing, and which is configured and operable for opening and closing the upper part of the casing, movable blade mounted in the casing, a fixed blade mounted in the lid, the movable blade and the stationary blade being movable to cut a printed medium having print applied thereon by engaging the blades with each other, the fixed blade being a single-edged blade having a blade surface arranged so that a blade surface faces an upstream side in the direction of transport of the printed medium, the fixed blade has a cutting edge on a cutting edge line and also has a root
- a cover slidably mounted on the fixed blade shaped and configured so as to cover the cutting edge line of the fixed blade from the side of the blade surface when the lid portion is released,
- wherein the cover is configured to slide toward the root of the fixed blade to expose the cutting edge line of the fixed blade when the lid portion is closed.
A cutting apparatus integrated into a printer having a lid portion which is capable of opening and closing an upper part of a casing body and a printing unit having a thermal head and an ink ribbon transporting mechanism mounted thereto, provided between the lid portion and the casing body, and configured to be fitted to and released from the lid portion and configured to cut a printed medium having print applied thereon by moving a movable blade mounted in the casing body toward a fixed blade mounted in the lid portion and engaging the same with each other, the fixed blade being a single-edged blade arranged so that a blade surface faces the upstream side in the direction of transport of the printed medium, comprising:
- a fixed-blade holder having the fixed blade mounted thereon and configured to cause the fixed blade to be retracted so as not to come into contact with the printing unit when the printing unit fitted in the lid portion is pulled out;
- covering means slidably mounted on the fixed blade so as to cover a cutting edge line of the fixed blade from the side of the blade surface when the lid portion is released;
- an urging device mounted on the fixed-blade holder and configured to urge the cover toward the cutting edge line of the fixed blade;
- and
- a projection projecting in the urging direction of the urging device and formed on both ends of the cover spaced at a distance wider than the width of the printed medium and at positions out of the area of a transporting path of the printed medium, wherein
- the cover being configured for a sliding movement of the cover toward the cutting edge line by an urging force supplied by the urging device when the lid portion is released so that the cutting edge line of the fixed blade is covered with the cover, and
- such that the cutting edge line of the fixed blade is exposed from the cover by a sliding movement of the cover toward a root of the fixed blade against the urging force of the urging device and caused by abutment between the projection on the cover with an abutted area provided on the casing body when the lid portion is closed.
