Description

The present invention relates to a mountless label insertion device of a portable mountless label sticking machine, and in particular, there is no portable mount for loading and transferring a strip-like mountless label and performing a sticking operation on a desired adherend. The present invention relates to a label insertion device without a mount of a label applicator.

2. Description of the Related Art Conventionally, a label is attached to various products and other objects to be attached using a portable label applicator, and the price of the product and other necessary information are displayed.
When using this portable label applicator, in a state where the label is rolled up, it is loaded and held in a holder such as a paper holder in the portable label applicator, and the label is fed out from the paper holder into a belt shape. It must be inserted into a portable label applicator and loaded in a state where it can be transferred or printed.

As a label to be loaded into the portable label applicator, it has a strip-shaped label base material, an adhesive layer provided on the back surface of the label base material, and a release agent layer provided on the surface of the label base material, There is a non-mounting label without a mount, and the non-mounting label can contribute to resource saving because it does not have a mount.
In the portable labelless label applicator used by loading and using the label without a mount, a mechanism for pressing the press member against the transfer roller portion and engaging the label without the mount to be loaded and transferred in the machine is necessary. When loading a label without a mount, a mechanism is required that allows the label without a mount to be inserted by opening and closing between the transfer roller and the pressing member.

    However, the conventional portable baseless label sticking machine has a problem that the number of parts of the opening / closing mechanism or the insertion mechanism between the pressing member and the transfer roller is large, and the opening / closing operation and the insertion operation itself are troublesome.
