Abstract
A cutting device and a printer having a cutting device eliminate paper jams and other transportation problems that can occur as a result of the cutting device cutting the paper, and can cut and reliably discharge the paper in a stable condition. The cutting device has a fixed knife 21, a transportation path 13 through which label paper 11 is conveyed, and a movable knife 22 that moves bidirectionally to the fixed knife 21 and cuts the label paper 11 on the upstream side of the fixed knife 21 on the transportation path 13. A catching unit 22b is disposed to the surface of the movable knife 22 on the upstream side of the transportation path 13, and catches the cut end of the label paper 11 after the movable knife 22 moves to the fixed knife 21 side and cuts the label paper 11.
Claims24
A cutting device, comprising:
- a fixed blade;
- a conveying path through which a sheet is to be conveyed;
- and
- a movable blade disposed on an upstream side of the fixed blade with respect to the conveying path, facing the fixed blade across the conveying path, and configured to move relative to the fixed blade in a reciprocal manner to cut the sheet in cooperation with the fixed blade, wherein
- the movable blade includes a catching unit disposed at a position on an upstream side of the movable blade with respect to the conveying path and configured to catch an end portion of the sheet upon separation of the movable blade from the fixed blade after cutting the sheet.

- a print process unit configured to print on a sheet;
- and
- a cutting device configured to cut the sheet, the cutting device including
- a fixed blade;
- a conveying path through which a sheet is to be conveyed;
- and
- a movable blade disposed on an upstream side of the fixed blade with respect to the conveying path, facing the fixed blade across the conveying path, and configured to move relative to the fixed blade in a reciprocal manner to cut the sheet in cooperation with the fixed blade, wherein
- the movable blade includes a catching unit disposed at a position on an upstream side of the movable blade with respect to the conveying path and configured to catch an end portion of the sheet upon separation of the movable blade from the fixed blade after cutting the sheet.
