Press.

When the print key 18 is pressed, the tape forming device 12 drives a pulse motor (not shown) to rotate the ribbon take-up spool 32 and the tape feed roller 34, whereby the ink ribbon 54 and the print medium 4 are printed.
0 and the double-sided tape 44 are fed at a predetermined speed along the path in the tape cassette 10 described above.

Along with the driving of the pulse motor, energization of the thermal head 58 is controlled by a well-known method based on the input data such as characters and symbols to heat the heating element. As a result, the ink 53 of the ink ribbon 54 is transferred onto the printing medium 40. The transferred ink represents a state in which the input characters, symbols, etc. are horizontally reversed on the ink transfer surface of the printing medium 40.

Then, as described above, the transparent adhesive material 46 of the double-sided tape 44 is adhered to the ink transfer surface of the printing medium 40 between the tape feeding roller 34 and the aligning roller 74 to form the tape 76. .. Formed tape 7
In FIG. 6, since the ink 53 transferred through the transparent print medium 40 can be seen from the surface of the print medium 40 on which the ink 53 is not transferred, the transferred ink 53 represents the input characters or symbols. To do.

After the tape 76 is formed, the pulse motor is continuously driven for a predetermined time to make a margin on the tape 76 on which desired characters and symbols are expressed.

After that, the tape making device 12 stops the driving of the pulse motor and maintains the next input waiting state.

In this state, the cutting lever 80 is shown in FIG.
Then, the tape 76 is swung in the direction A shown in FIG.

In this way, a desired character or symbol is expressed, and the tape 76 is prepared which is peeled off the release paper 42 and attached to an arbitrary place.

The produced tape 76 is attached to an arbitrary place as a means for displaying a headline of a note or a file and a necessary matter on a machine, and thus is often exposed to sunlight (ultraviolet rays). As shown in FIG. 1, the ultraviolet ray opaque material of the medium to be printed 40 forming the uppermost layer of the tape 76 blocks the ultraviolet rays applied to the medium to be printed 40.
Since the ink 53 transferred to the lower layer and the base color print layer 50 are protected from ultraviolet rays, the colors of the ink 53 and the base color print layer 50 do not fade. In particular, it prevents fading of the tape 76 in which the base color print layer 50 of the double-sided tape 44 uses a fluorescent color that is weak to UV irradiation.

The present invention is not limited to this embodiment described in detail above, and various changes can be made without departing from the spirit of the present invention.

For example, in the print medium 40 used in the tape cassette 10 of this embodiment, a polyethylene film is impregnated with an ultraviolet ray opaque material. The ultraviolet ray opaque material is applied to the surface of a transparent film such as a polyethylene film. It may be the one given.

The tape cassette 10 of this embodiment is provided with a print medium tape spool 26 around which a print medium 40 is wound, a double side tape spool 28 around which a double-sided tape 44 is around, and an ink ribbon 54. Although the ribbon supply spool 30 and the ribbon take-up spool 32 are rotatably arranged, the ribbon supply spool 30 and the ribbon take-up spool 32 around which the ink ribbon 54 is wound may be removable.
