Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a multi-color εψ thermal transfer i4+, which records information by transferring ink from a transfer sheet to fi+j M paper, which is used as bamboo tags or labels, etc., by the thermal action of a thermal head 3b. A recording device, more specifically, an improvement of a multicolor thermal transfer recording device that is capable of forming an adhesive part at a predetermined position on M+ and lamp paper in a continuous process after information is recorded.
do.

The transfer type thermal recording method in this building is capable of recording 0 copies of A'lk-\ compared to the conventional coloring type thermal recording method, and is superior to the inkjet method in terms of print density and print storability. In comparison, printing can be done with a simple Yamanaka mechanism, etc.)
In addition to having 11 points, there is less noise and the impression speed is I!
It is known as a very outstanding method among the so-called non-impact recording methods that have a fast l.

However, in conventional thermal transfer recording devices, the thermal head that performs the transfer and the platen facing it are always compressed, and the transfer sheet and the recording ax are held in close contact with each other during the recording process. Since the system uses a method in which both are integrated and transported between the thermal head and the platen, even if there is a part of the recording paper that does not require printing, the transfer sheet will not be transferred. Since the transfer sheet is conveyed without being covered, there is a disadvantage that a far larger amount of transfer sheet is wasted compared to the actual printing area.

In addition, as a means to prevent such drawbacks of the conventional method, the transfer sheet is braked in areas where printing is not performed on the recording paper, and only the recording paper is conveyed while causing friction between it and the recording paper. There are methods to do this, but 1. In this type of method, when high-speed printing is desired, the melting point of the ink in the high-speed transfer sheet is low and the paste material is thin, so the thermal head and platen are sandwiched between the thermal head and the platen, which are pressed against each other. In some areas, unnecessary transfer occurs due to the pressing force and frictional heat between the transfer sheet and the recording paper, which may stain the recording paper. There were problems such as the transfer sheet being easily cut due to the stress.

Therefore, as in the invention disclosed in Japanese Patent Application No. 47'-193834 filed on November 4, 1987 by the present applicant, a device is installed to apply pressure between the thermal head and the thermal head. , it is IN to the extent that the platenology that has been suppressed is suppressed.
By providing a mechanism for moving between the position and the position where the suppression can be released, and controlling this mechanism depending on the presence or absence of a print signal, at the location where printing is performed,
The platen roller is configured to press against the thermal head, and the transfer sheet and recording paper are integrated and printed while being conveyed.On the other hand, in areas where printing is not performed, the pressure between the platen roller and the thermal head is It has been proposed that by releasing the suppression, conveyance of the transfer sheet is stopped and only the recording paper is conveyed, thereby minimizing wastage of the transfer sheet and preventing staining of the recording paper. .

However, in the above-mentioned prior invention, when recording paper is used for issuing tags, labels, etc., there is no mechanism for attaching an adhesive part to the recording paper, so it is necessary to attach the adhesive part to the recording paper in advance in the process before thermal transfer recording. It is necessary to apply adhesive tape or glue to give an adhesive υ■ process, or to perform an adhesive process in a subsequent process. With the method of applying glue using a glue roller or the like, it is not possible to paste or apply glue accurately and quickly to the 7 fixed positions of the recording paper, and there are problems such as maintenance and drying time. It's not convenient. In addition, pre-glued recording paper has weak adhesive strength, and its adhesive strength decreases over time, causing it to lose its original function as a tag or label. There is a risk that the platen o-roller etc. may be contaminated during transportation within the device. Furthermore, with recording paper that has been provided with an adhesive part in advance in the pre-transfer process, it is not possible to store a large number of recording papers due to the thickness of the adhesive part.
Moreover, when printing, the difference in the thickness of the adhesive part causes poor contact with the thermal head, causing uneven printing.
"There is a potential.

This invention provides a mechanism for attaching an adhesive part to the thermal transfer recording device in the apparatus of the prior invention, thereby making it possible to record information on recording paper and form an adhesive part in a continuous process. The object of the present invention is to provide a thermal transfer recording device.

Hereinafter, the present invention will be explained in detail based on an illustrated embodiment.

It has increased by 44% from the previous Soviet Union. Furthermore, a feed roller 6 is rotatably mounted on the holding portion 5 that holds the platen roller 2, and this feed roller 6 is.

Inside the cassette, there is a transfer sheet feeding roll 8, which is positioned opposite to the guide roller 11 of the transfer sheet feeding roller 11, which is passed through the four stages via the V roll 9 and the corner 10, and is perpendicular to the plane of the paper in this cassette yrlz Fig. 1. 4 if one person is placed from the side lII+ on the side ζ of the device, and the lower part thereof has a concave shape with a medium heat part, and the thermal head I fits into this concave part to transfer the transfer sheet)11
The exposed portion of the head is in contact with the heat generating surface on the lower surface of the thermal head.

1. The recording paper P is wound around a feeding roll 12 supported by an arm, and is delivered via a tension roll 13 to the f-id roll Z4 at the pre-transfer recording position, and is then transferred to the plurality of thermosensitive units described above. The recording paper P is conveyed between the head 1 and the platen roller 2 so that it can run in close contact with the transfer sheet R at each transfer recording position, and a cut mark a is marked on the recording paper P. This cut mark a is detected by a cut mark sensor 15 provided opposite to the guide roller 4, and based on this signal,
The recording paper is cut into a predetermined length using a force provided on an adhesive section attachment block, which will be described later.
