Abstract

PURPOSE:To attain to enhance printing quality, by a method wherein a heating roll is provided between a paper feed roll and a printing head and printing paper withdrawn from a paper feed roll is heated by said heating roll to be subjected to ink jet printing. CONSTITUTION:Printing paper is withdrawn from a paper feed roll 13 is guided to a heating roller 24 functioning as a guide roller to be heated in contact relation thereto and the heated printing paper is subjected to ink jet printing by a printing head 1 to be guided and supplied between a paper feed roller 11 and a press roller 12. In this case, it is pref. that a separate heating roller 27 is provided between the printing head 1 and the paper sending roller 11 and the printing paper after printing is brought into contact with said heating roller 27 to dry a printing ink under heating.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device, and in particular, in a recording paper feeding device of an inkjet printer, a heating roller is preheated with a 19-degree sickle WAIIA before printing is performed by a print head.
This is intended to improve the quality of printing of record names.

FIG. 1 shows a prior example of a recording device, where / is a print head having nozzles for printing.In this example, a color inkjet is shown, so that there are two printers in the cartridge. Print heads are fixed for each color. The carriage λ is fitted in a guide wheel 3 so as to be freely movable 9 and is driven laterally by a head feed motor 19 via a timing belt tl, and during this movement it prints on the recording paper 4. , is an ink tank that supplies ink to nozzles (not shown) of the print head;
l is the supply pipe, To9, and the head/is a flexible wiring board? A print signal is then supplied. 10 is a pulse motor that drives the paper feed roller //if, and the presser roller /- is kept in contact with the paper feed roller //, and the recording is performed between the rollers l, 1 and 1 of cn, etc. The recording paper 6 that is held between the sheets 4 and 6, which is wound around the paper supply roll /3, is moved under tension to the lower guide roller /4.
From t to upper guide row ′)/! It is then guided between the paper feed roller // and the presser roller saw, and is then pulled out to the storage position.

However, in general, there are two types of recording devices:
The recording paper 4 wound around the paper supply roll 13 contains moisture, which causes it to adhere during printing and cause dots to smear.In addition to this, the printed records are not sufficiently fixed. Paper 4 is placed in the paper feed row 2/
/ and the presser roller saw, so that unfixed print records are retransferred onto the recording paper via the roller saw.
Both of these things reduce the product value. In particular, when recording is done by color inkjet, the above-mentioned tendency is remarkable as it takes several minutes to fix the ink because the ink/print is overprinted.

The purpose of the present invention is to eliminate the above-mentioned defects, to preheat the recording paper by touching the heating roller KJI immediately before printing with the print head, and to dry the paper and prevent bleeding.
An object of the present invention is to provide a recording device capable of promoting the fixation of a 19-character printing plate when paper is heated.

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

FIG. 1 shows an embodiment of the present invention, where J is a heating roller incorporating a heater, and in this example, this heating roller i is provided at the position of the lower guide loaf/da explained in FIG. . The other configurations are almost the same as those in FIG. 7, and will be omitted for the sake of explanation. In the recording device configured in this way,
Since the paper 4 led from the paper supply roll 3 is preheated in contact with this heating roller Koda, the heating prevents the ink from bleeding and making noise when printing 19, and furthermore, the fixation of the print is promoted. nru.

FIG. 3 shows another embodiment of the present invention, in which the bait is a heating roller for preheating the paper sheet in the same way as shown in FIG. O-L-4 is a heating roller. That is, in this example, the heating roller 2 is used to preheat the paper 6, and the paper 6 that has been printed is heated from the back side and the front side by the heating roller 2, so that printing can be done easily. Fixation can be made even more reliable.

Figure II1 shows still another embodiment of the present invention. In this example, two heating rollers with a large diameter are provided in addition to the heating roller, and this heating is applied to the paper 61 printed by the print head. By bringing the paper into contact with the roller 7 over a wide area, it is possible to promote the fixation of the print, and in combination with the preheating of the paper sheet B by the heating roller, it is possible to further increase the product value of the recording paper.

Please explain the above! ↓According to the present invention, a heating roller is provided at a position immediately before printing is performed, and the heating roller preheats the recording paper to dry the paper and print in a warmed state. Since it is made L, it is possible to prevent the ink dots from bleeding during printing due to the moisture of the recording paper, and furthermore, it is possible to promote the fixation of the print.

In addition to the heating roller described above in 11, the printing i [bond Wi
If you install a heating roller that heats the paper from the back side, the fixation of the print will be even more reliable.
