And a holding mechanism for the tape-shaped backing sheet.

(Prior Art) As this kind of prior art, as shown in, for example, Japanese Patent Application Laid-Open No. Sho 58-112786 (portable label sticking apparatus) of the present applicant, see FIG. The take-up cassette (1) having the take-up core (8) is provided with a mount holding mechanism (18). The backing mechanism (18)
The spring (26) housed in the recess (19) formed in the machine frame (7) is urged downward by the action of the spring (26) and the needle (2
3) and a receiving plate (2) formed with a hole (28, see FIG. 5 of the same publication) for receiving and disengaging the needle (23).
This is a combination with 1). Thus, the label continuous body (4) wound around the winding core (8) is turned by the turning pin (16) at the front of the cassette, and the label is peeled off. Then, the remaining tape-shaped mount (5) is pierced and locked by the needle (23) provided on the pressing member (20) through the mount guide groove (15).

Thus, in order to peel off the label (6) from the label continuous body (4) loaded in the take-up cassette (1), it is necessary to pull the tape-shaped backing sheet (5). At the time of this pulling, means for releasing the locked state of the needle (23) with respect to the tape-shaped mount (5) is required. The releasing means is a label sticking machine (2) in which engaging tongues (25), (25) protruding on both sides of a cassette formed integrally with the pressing member (20) on the winding cassette side abut. (See FIG. 6 of the same publication). The lock is released by the lifting action of a push-up plate (60) that operates when grasping a hand lever (41) provided in the labeling machine. The tape mount (5) engaged with the transfer claw (45) of (2) is pulled. The label (6) is peeled off by this traction action.

(Problems to be Solved by the Invention) In holding the tape-shaped backing sheet in the label cassette, in the above-described conventional method, the needle is directly pierced into the tape-shaped backing sheet and locked, so that the number of parts is large and the mechanism is complicated. In view of such a defect, an elastically biased mount holding member (first mount holding member) having no needle engagement is used instead of the needle engagement to sandwich and hold the tape-shaped mount.

In addition, the transfer (pulling) of the mount is considered in consideration of the transfer of the mount, and the transfer is reliably and smoothly performed (the second mount pressing member).
