Description

  The present invention relates to a label printer that prints on a label temporarily attached to a belt-like mount, and in particular, a normal issue state in which a label is issued while the belt-like mount is temporarily attached, and a peel-off issue state in which a label is issued after being peeled from the mount The present invention relates to a label printer that can be used by switching between and.

  A label printer is a device that prints and issues a label temporarily attached to a belt-like mount, and issues a state in which a label is issued while the belt-like backing is temporarily attached (hereinafter referred to as a normal issue state) and a belt-like mount. 2. Description of the Related Art There is known an apparatus that can be switched to a state in which it is peeled and a label is issued (hereinafter referred to as a peeling issuance state).

  As a method of switching between the normal issue state and the peel issue state, the peeler is rotatably provided around the rotation axis of the platen roller, and the levers provided at both ends of the peeler are operated to rotate. There has been proposed an apparatus that performs switching by changing the turning angle of a belt-like mount on which a label is temporarily attached (see, for example, Patent Document 1).

However, in the prior art, it is necessary to operate the levers provided at both ends of the peeling body for switching between the normal issuing state and the peeling issuing state with the open / close cover open, so that the device is not used during the switching operation. If it falls, there is a problem that the risk of breakage increases. In other words, in the case of a portable label printer that is worn on the body, robustness against dropping is required, but the size of each part is reduced by downsizing and the strength of each part is weakened. Therefore, the robustness is secured in the assembled state, and when the open / close cover is opened, the robustness is remarkably lowered, and the open / close cover is opened. If you drop it, the risk of breakage increases.
