[Prior art]
A label printer is a device that prints and issues a label temporarily attached to a belt-like mount. This label printer has a case where a label is issued while temporarily mounting a mount (hereinafter, standard mode) and a case where a label is released after being released from the mount (hereinafter, peeling mode).
[0003]
The standard mode label printer continuously prints a predetermined number of labels, and the printed label is temporarily attached to the mount and sent out from the take-out port to separate the belt-like mount. And when using, a label is peeled from a strip | belt-shaped mount sheet | seat one by one.
[0004]
The label printer in the peeling mode prints one label at a time, and peels off the label from the strip to issue. The issued label is kept waiting at the outlet of the printer main body, and taken out when used.
[0005]
Incidentally, a label printer having both the standard mode and the peeling mode usually has two types of paper routes. That is, a paper route for a peeling mode having a peeling means for the mount and a paper route for a standard mode having no peeling means are provided, and the mode is changed by changing the paper route by a switch.
[0006]
[Problems to be solved by the invention]
However, the conventional label printer requires two types of paper routes and requires a separate switch for mode switching, which has the disadvantage of increasing the size of the apparatus. Furthermore, there is a drawback that the mode switching control such as sensor ON-OFF control is complicated. For this reason, simplification of the device structure has been demanded, and in particular, improvements have been desired in portable label printers that need to be reduced in size and weight.
