Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inkjet recording device, and in particular, in a recording paper feeding device of an inkjet printer, the recording paper is preheated by a heating roller before recording is performed by the recording head, and the quality of the printed characters is improved. It was designed to increase the

FIG. 1 shows a prior example of an inkjet recording apparatus, where 1 is a recording head having nozzles for recording. In this example, a color inkjet is shown, and therefore, four recording heads are fixed to the carriage 2 for each of the four colors. The carriage 2 is fitted onto a guide shaft 3 so as to be freely movable, and is driven laterally by a head feed motor 4 via a timing belt 5.
During this movement, printing is performed on the recording paper 6 in the recording area facing the recording head. 7 is an ink tank for supplying ink to nozzles (not shown) of the recording head 1; 8 is a supply pipe thereof; print signals are supplied to the head 1 through a flexible wiring board 9; Reference numeral 10 denotes a pulse motor that drives the paper feed roller 11. A presser roller 12 as a conveying member is kept in contact with the paper feed roller 11, and A recording paper 6 is held between the recording material conveying means. That is, the recording paper 6 wound around the paper supply roll 13 is recorded while being guided from the lower guide roller 14 to the upper guide roller 15 while maintaining tension, and is then guided between the paper feed roller 11 and the presser roller 12. between the two and pulled out to the storage position.

However, in such an inkjet recording apparatus, the recording paper 6 wound around the paper supply roll 13 generally contains moisture, which causes the adhered ink dots to smear during recording. In addition to this, since the printed records are guided between the paper feed roller 11 and the presser roller 12 without being sufficiently fixed, the unfixed printed records are transferred to the recording paper via the roller 12. 6
Re-transfers may contaminate the record, all of which reduce the value of the product. In particular, when recording is performed using a color inkjet, the ink is overprinted, so it may take several minutes to fix the ink, and the above-mentioned tendency is noticeable.

An object of the present invention is to eliminate the above-mentioned drawbacks, and to preheat the recording paper by bringing it into contact with a heating roller immediately before recording with the recording head, thereby drying the paper to prevent bleeding, and to warm the paper. An object of the present invention is to provide an inkjet recording device that can promote the fixation of printed records.

The present invention has been proposed to achieve the above object, and is an inkjet recording device equipped with a recording head that records on a recording material by discharging ink into a recording area. The apparatus is characterized in that a heating means for preheating the recording material is provided within the conveying section of the recording material.

Further, the present invention provides an inkjet recording device equipped with a recording head that records on a recording material by discharging ink in a recording area, in which an inkjet recording head is provided which is located outside the recording area and extends up to the recording area. a first heating means for preheating the recording material within the conveyance section of the recording material; and a first heating means for applying heat to the recording material within the discharge section of the recorded recording material discharged from the recording area. and a second heating means for providing heating.

The present invention will be explained in detail below based on the drawings.

FIG. 2 shows an embodiment of the invention, where 2
4 is a heating roller incorporating a heater, and in this example, this heating roller 24 is provided at the position of the lower guide roller 14 explained in FIG. The rest of the configuration is almost the same as that in FIG. 1, and the explanation thereof will be omitted. In the recording apparatus configured in this manner, the paper 6 guided from the paper supply roll 13 is preheated by contacting the heating roller 24, so that the warming prevents ink from bleeding during recording. This further promotes the fixation of records.

FIG. 3 shows another embodiment of the invention, where:
24 is a heating roller for preheating the paper 6 as shown in FIG. 2, and 25 and 26 are also heating rollers. That is, in this example, the paper 6 is preheated by the heating roller 24, and the paper 6 on which recording has been completed is heated from the back and front surfaces by the heating rollers 25 and 26, so that the fixation of the recording is further ensured. It can be done.

FIG. 4 shows yet another embodiment of the invention. In this example, a heating roller 27 with a large diameter is provided in addition to the heating roller 24, and by bringing the paper 6 recorded by the recording head 1 into contact with this heating roller 27 over a wide area, the recording is fixed. Therefore, in conjunction with the preheating of the paper 6 by the heating roller 24, the product value of the recording paper can be further increased.

As described above, according to the present invention, a heating roller is provided at a position immediately before recording is performed, and the heating roller preheats the recording paper to dry the paper and keep it in a warmed state. Since the ink dots are recorded, it is possible to prevent the ink dots from bleeding during recording due to the moisture of the recording paper, and furthermore, it is possible to promote the fixation of the recording.

Further, in addition to the above-mentioned heating roller, if a heating roller is provided which heats the recording paper immediately after recording from the back side thereof, the recording can be fixed even more reliably.

As described above, in the present invention, since no heating means is provided in the recording area where recording is performed by the recording head, the recording head is not overheated. Therefore, even when using a recording head that performs recording by ejecting ink from the ejection opening, it is possible to prevent ink from evaporating, and there is no reduction in recording quality due to clogging of the recording head. .
