Abstract

PURPOSE:To supply a tape printer which is small in size per se and contains a small-size cassette having a long printable tape length per unit. CONSTITUTION:A printing tape producing device is provided with a transparent polyester film 8 coated with a heat-sensitive solvent forming a color when heated on one surface thereof; a printing means which brings a thermal head 5 into contact with the film 8 to print characters, image, or the like thereon in a reverse form; a pressure-sensitive double-sided adhesive tape 9 with separator; and two rollers 10, 12 disposed in the vicinity of the printing means. A printing tape is formed by bonding the double-sided pressure-sensitive adhesive tape 9 with separator on the printed surface of the polyester film 8.

2. Description of the Related Art Conventionally, this type of technology includes an ink ribbon which is arranged in a row on a thermal head in a removable cassette and performs transfer by selective heat generation of printing elements;
A transparent film for printing, a double-sided tape with a separator attached to the back side of the film to be pasted to the printed side, reversed characters, images, etc. are printed on the transparent film, and the double-sided tape It was stuck together with tape and discharged outside the device. In addition, there was also a cassette in which the ink ribbon was taken out from the cassette, a cassette for the ink ribbon was formed, and the cassette was combined with a cassette containing a printing film and a double-sided tape with a separator on the back side.

[Problems to be Solved by the Invention] However, in the above-mentioned prior art, an ink ribbon wound into a roll, a transparent film, a double-sided tape, and a core for winding the ink ribbon are arranged inside the cassette. As a result, the external size of the cassette was quite large. On the other hand, the length of tape that could be printed with one cassette was quite short, less than 10 m. In addition, an ink ribbon winding mechanism was required in the main body of the printing device, and there was a limit to miniaturization of the main body. It had these problems.

The present invention was made to solve these drawbacks, and its purpose is to reduce the length of tape that can be printed with a single cassette, while making the printing device itself and the built-in cassette small. An object of the present invention is to provide a tape printing device capable of mounting a long cassette.

[0005]

[Means for Solving the Problems] The tape printing apparatus of the present invention includes a transparent polyester film coated with a heat-sensitive solvent that develops color by heat on one side, and a thermal head on the side of the polyester film coated with the heat-sensitive solvent. It has a printing means for reversing printing of characters, images, etc. by contacting it, a double-sided tape with a separator, and two rollers arranged near the printing means, and the printing surface of the polyester film is coated with the separator. This is a printing tape manufacturing device characterized by laminating double-sided tapes together to form a printing tape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a printing tape manufacturing apparatus according to an embodiment of the present invention. Reference numeral 1 denotes the main body of the printing tape production device, 2 a circuit board for controlling a thermal head 5 in which a plurality of printing elements are arranged in a row, and a stepping motor 5 that drives rubber rollers 3 and 12 for moving the printing tape; Once every 0.141 mm of tape feed,
Some of the printing elements arranged in a row on the thermal head are selected and generate heat. 7 is a double-sided tape 9 with a separator on the back side, a printing material 8 whose surface is coated with a heat-sensitive solvent that develops color by heat, and a rubber roller 12 fixed to the main body 1 that is pressed against the printing material 8 and the back surface. The main body 1 is composed of a rubber roller 10 that pulls out a double-sided tape 9 with a separator attached while pasting it together.
It is a removable cassette. 11 is an opening of the main body 1, through which the printed tape is discharged.

FIG. 2 is an enlarged cross-sectional view of the printing section of the printing tape manufacturing apparatus and the section where the double-sided tape 9 and the printing material 8 are pasted together in an embodiment of the present invention. The printing substrate 8 is composed of a base film 8a made of polyester and a heat-sensitive solvent 8b that develops color when heated. The base film 8a
The thickness must be at least 30 μm, as if it is too thin, it may cause twisting or wrinkles during printing or pasting.
Furthermore, if the thickness is too large, the length that can be accommodated within the cassette will be extremely short, so it is preferable to set the thickness to about 200 μm. The heat-sensitive solvent 8b can develop various colors such as black, red, blue, green, and brown depending on the solvent used.
There is no difference from transfer printing using an ink ribbon. The double-sided tape 9 is composed of an adhesive 9a and a separator 9b.Double-sided tapes of various colors can be made by adding pigments to the adhesive 9, and printed tapes of various base colors can be supplied. If the separator 9b is thick, it may cause winding nests when it is wound into a core shape.
If the separator is too thin, the separator cannot be easily peeled off from the printing tape, so it is preferable to use a thickness of about 75 μm. The thermal head 5 synchronizes with the driving of the stepper motor 2.
Due to the selective heat generation of the elements arranged in the upper row,
As the heat-sensitive solvent 8b on the printed material 8 develops color and prints characters, images, etc., the rubber rollers 12 and 10 rotate using the stepping motor 2 as a driving source to remove the printed material 8 and the double-sided tape. are moved and pasted together to produce a printing tape as shown in FIG. The heat generated by the thermal head 5 sends data from the circuit board 4 so that characters and the like can be recognized when viewed from the base film 8a side of the printing medium 8.

FIG. 3 is a front and cross-sectional view of the manufactured printing tape. In the case of a thermal printing method, mechanical force on the thermal solvent 8b, such as long-term light irradiation or rubbing, may cause
There was a drawback that the heat-sensitive solvent 8b developed color or the color development faded. However, according to the configuration shown in FIG. 3, the base film 8a can cut out some light and protect the coloring agent 8a from mechanical force, thus solving the drawbacks of the thermal printing method.

[0009]

As described above, according to the present invention, the length of the printable tape can be adjusted by using the ink ribbon inside the cassette.
It is possible to provide a small-sized printing tape production device that is several steps longer than the one in which a printing material and a double-sided tape with a separator are arranged, and can be equipped with a small-sized cassette.
