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.

Abstract: A label peeling unit having an installation body: a movable body movable while engaging with the installation body and stopping in a closed state or an open state in which the movable body is closed or open relative to the installation body; a label peeling body installed on the movable body and allowing backing paper of a continuous label body, which is conveyed by the paper sheet conveyance device, to be in contact with the label peeling body to bend the backing paper for peeling a part of a label off the backing paper; and a backing paper conveyance roller rotatably installed on the movable body and rotating while being in contact with a platen roller of the paper sheet conveyance device with the backing paper in between to thereby convey the backing paper and discharge it to the outside. The label peeling unit facilitates loading of paper sheets.

Abstract: A label printer includes a cutter mechanism, a main body frame, and an upper cover. The cutter mechanism includes an upper blade which is a fixed blade and a lower blade which is a moving blade that advances and retreats relative to the upper blade, and that cuts a printing medium by causing the lower blade to advance and retreat relative to the upper blade. The lower blade is attached to the main body frame. The upper blade is attached to the upper cover, which opens and closes an upper portion of the main body frame. The upper blade is separated from the lower blade when the upper cover is opened.

Abstract: An aluminum alloy sheet for printing plate contains Fe: 0.2 to 0.6 Wt %, Si: 0.03 to 0.15 Wt %, Ti: 0.005 to 0.05 Wt %, Ni: 0.005 to 0.20 Wt %, and remainder of Al and inevitable impurity, wherein a ratio of Ni content and Si content satisfies 0.1.ltoreq.Ni/Si.ltoreq.3.7. The aluminum alloy sheet is manufactured by homogenizing an aluminum alloy ingot at a temperature in a range of 500.degree. to 630.degree. C., after performing hot rolling at start temperature in a range of 400.degree. to 450.degree. C., providing cold rolling and intermediate annealing, and further performing final cold rolling. By this, the aluminum alloy sheet for printing plate is prevented from pit generation upon dipping in electrolytic solution in a condition where an electric power is not applied. Uniformity of grained surface of the aluminum alloy sheet by electrolytic treatment can be improved.
