DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an image receptor which is used with the image receptor contained in a cassette in a tape printer.
BACKGROUND ART
The tape printer is provided with simple word processing function and printing function, and is adapted to form printed images (letters, symbols, bar codes, etc.) while unwinding an image receptor in the form of a tape which is wound in a pancake-like shape (a roll-like shape) and to cut off a portion of the image receptor in which the printed images are formed. This cut piece is stuck onto an object as a label. With use of the tape printer it is possible to form a header label, name label, bar code label, and the like, with ease.
A thermal printer is usually employed in the printer part of such tape printer because it can be easily scaled down. Therefore, an ink ribbon to be used therein is usually a thermal transfer ink ribbon.
As the image receptor in the form of a tape for use with such a tape printer, there is known an image receptor of the type which includes an image receptor body comprising a foundation film, such as polyester film, provided on one side thereof with an image-receiving layer such as made of a polyester resin which allows a thermal transfer ink to exhibit good fixing property, and on the other side thereof with a pressure-sensitive adhesive layer, and a release material stacked on the pressure-sensitive adhesive layer of the image receptor body. With this image receptor, a printed image is formed on the image-receiving layer, a desired length of the image receptor including the portion where the printed image is formed is cut off and the release material is then exfoliated from the cut piece, and the remaining image receptor body is stuck at its pressure-sensitive layer side on an object.
FIG. 4 is a plan view showing an example of the tape printer. Note that the word processing function part is not illustrated.
In FIG. 4, numeral 30 denotes a casing of the tape printer. The casing 30 are provided with a thermal head 31, a driving roller 32, a cutter 33 and an outlet for image receptor. A cassette 40 is contained in the casing 30.
An image receptor 20 and a thermal transfer ink ribbon 41, which are each wound in a pancake-like shape, are contained in the cassette 40. The image receptor 20 and the thermal transfer ink ribbon 41 are respectively unwound and fed to between the driving roller 32 and the thermal head 31, where printing is conducted. After printing, the image receptor 20 separated from the ink ribbon 41 is led to the exterior from the image receptor outlet 34. After printing has been conducted on a desired length of the image receptor, it is cut with the cutter 33. The ink ribbon 41 used for printing is wound up on a take-up core 42. Numerals 43 and 44 denote guide rollers for the image receptor 20, and numeral 45 denotes a guide roller for the ink ribbon 41.
However, with use of the conventional tape printer image receptor, there occur frequently a phenomenon that the release material is partially lifted from the image receptor body during traveling in the cassette 40 (hereinafter this phenomenon is simply referred to as "lift"), resulting in such inconveniences that the image receptor does not run smoothly and, in an extreme case, the image receptor carrying printed images does not come out of the tape printer. This lift is due to the bending of the image receptor during travel in the cassette. Further description of these phenomena will be made with reference to the drawings.
FIG. 5 is an explanatory view for illustrating a lift produced in the image receptor. A release material 22 is partially lifted from an image receptor body 21 and, hence, a lift 23 is produced. In an extreme case, the height of the lift 23 (height H from the general surface of the release material, hereinafter the same) reaches up to 1 to 2 mm.
FIG. 6 is an explanatory view for illustrating the traveling state of the image receptor with such a lift produced in the tape printer. There is likely to occur such an inconvenience that the l
