As shown in FIGS. 2 and 3, a cutter 61 and a pressing member 62 are disposed near the hole 25 for the second drive roller 8 with the tape 5 interposed therebetween. Cutter 61
As shown in FIG. 4, a roller 63 is pivotally supported by upper and lower cases 20 and 21, a blade 64 is built in an intermediate portion of the roller 63, and a blade edge is disposed in parallel with the traveling direction of the tape 5. ing.

The roller 63 has a coil spring 65 interposed about a lower axis. One end 66 of the coil spring 65 is engaged with the roller 63 as shown in FIG. And a clockwise rotational force in the figure is applied to the roller 63. A stopper 69 is provided on the other side surface of the roller 63 so that the stopper 69 comes into contact with the side wall 21 a of the lower case 21 to restrict the rotation of the roller 63 so that the tip of the blade 64 faces the tape 5. ing. The amount of protrusion of the tip of the blade 64 is such that only the tape 5 is cut and the backing paper is not cut when the tape 5 described later is cut.

The pressing member 62 is pivotally supported by the upper and lower cases 20, 21 as shown in FIG. 4, and is formed in an eccentric type of cam shape. The knob 70 is fitted on the upper part and can be rotated by manual operation. . The lower shaft 62a of the pressing member 62 is formed in a quadrangular prism shape as shown in FIG. 5, while a substantially swastika-shaped notch 71 is provided in the lower case 21 to provide four elastic contact pieces 72,7.

Therefore, the pressing member 62 is rotatable by manual operation, and the elastic contact pieces 72, 72, 72, 72 exert a detent action every 90 degrees due to the pressure contact force. It is locked at a predetermined position without accidental rotation.

When the large diameter portion 62b of the pressing member 62 is brought into contact with the blade 64 of the cutter 61, the tape 5
2 and the blade 64, the tape 5 runs along with the printing operation of the tape printer 1, and only the tape 5 excluding the backing paper 5a is cut at a predetermined width. At this time, a rotational force in the counterclockwise direction in the drawing is applied to the cutter 61 by the running friction of the tape 5, but the blade 64 is pressed against the tape 5 with a constant pressure by the bias of the coil spring 65 described above. Disconnect.

When the tape 5 does not need to be cut, the pressing member 62 is manually rotated and locked at a position away from the cutter 61 as shown in FIG. To travel. It should be noted that the present invention is not limited to the present embodiment. Contrary to the present embodiment, the cutter 61 may be of a detent rotation type, and the pressing member 62 may be configured to be pressed by a spring. Also, blade 64
Various modifications can be made to the height position and the number of sheets, and it is natural that the present invention extends to those modifications.

[0019]

According to the present invention, as described in detail in the above embodiment, the cutter 61 disposed in parallel to the running direction of the tape 5 has its blade 64 cutting only the tape 5 from the surface of the roller 63. Since only the tape 5 is projected so as not to cut the backing paper, only the tape 5 is cut, and this cutting line is formed linearly on the tape surface, and the cut portion of the tape 5 has its adhesive property. As a result, the tape 5 adheres to the backing paper and travels without being separated, so that the traveling and printing operation of the tape 5 are performed smoothly. Further, the operation of separating the tape 5 printed and discharged to the outside from the backing paper is also facilitated because the backing paper protrudes laterally from the end of the cut tape 5.
