Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing tape cassette which can be used by being attached to a tape printing apparatus for printing an image on a tape by a method such as heating.

[0002]

2. Description of the Related Art Conventionally, a printing tape cassette, which can be mounted and used in a tape printing apparatus for printing an image on a tape by a method such as heating, has a printing tape and an ink ribbon incorporated therein. Then, the tape printing apparatus can create a tape on which an arbitrary image such as a character is printed by transferring the ink of the ink ribbon onto a printing tape by a method such as heating or pressing. I was able to do it. In addition, the tape thus produced can be used by adhering it to any solid substance.
For example, European Patent Publication No. 272232, Japanese Utility Model Application No. 62-1
It is disclosed in the specification and drawings of No. 99662.

However, in the printing tape cassette, the printing tape and the ink ribbon are housed in a state in which they are wound on separate spools, and furthermore, both the printing tape and the ink ribbon run independently. Since a fairly complicated mechanism is provided to achieve matching between the two while controlling, troubles such as entanglement and cutting of the ink ribbon are likely to occur. In addition, many of the components are consumable items, and their costs are high.

Therefore, in recent years, a printing tape on which an image can be printed without using an ink ribbon has been developed and has been made into a cassette. Here, a pressure-sensitive adhesive layer is applied on one surface of the base sheet of the printing tape, release paper is pasted on it, on the other surface,
A thermosensitive color developing agent layer capable of developing a color by heating is formed. An overcoat layer for water resistance, abrasion resistance, etc. is provided on the thermosensitive color developing agent layer.

[0005]

However, in the tape printer which can be used by mounting the conventional printing tape cassette containing the ink ribbon as described above, the used ink ribbon portion is appropriately wound. Winding roll
Therefore, when a tape cassette for printing that does not have an ink ribbon built therein is attached to the tape printing apparatus and used, the take-up roller does not have an ink ribbon to be taken up at the time of tape printing. Nevertheless, the winding operation is performed in the same manner as when the ink ribbon is present, but since it is in a free state, it spins around at high speed, which causes noise that is considerably offensive to the ear.

Therefore, in order to reduce the noise, it is conceivable to develop a new printing tape cassette, but if the cassette case is also newly added, the cost for the mold and the like is very high, and the cost is very high. there were. It is also possible to develop a tape printing device that only supports tape cassettes that do not use ink ribbons, but users who want to use tape cassettes that use ink ribbons also need two types of tape printing devices. Therefore, not only will the cost burden increase, but if you want to print the same print data with two types of tape, you will need to input the print data for each device. Was not.

The present invention has been made in order to solve the above-mentioned problems, and can be used by mounting it on an existing tape printer, and can reduce noise with a simple structure. It is an object of the present invention to provide a low-cost printing tape cassette provided with various means.

[0008]

In order to achieve this object, a printing tape cassette of the present invention is detachably attached to a printing device and stores a printing tape in a wound manner. Of the driving members that are provided on the apparatus side and that are driven during tape printing, there is provided resistance applying means that applies resistance to the drive portion of the unnecessary drive member.

[0009]

The printing tape cassette of the present invention having the above-mentioned construction is used by being mounted on an existing tape printing apparatus, and at the time of tape printing, resistance applying means applies resistance to unnecessary drive parts of the drive member. By adding the above, the generation of noise due to free rotation of the drive portion is prevented.
