Abstract

PURPOSE:To prevent the lowering of printing quality and the staining of recording paper, by a method wherein the recording paper subjected to ink jet printing is brought into contact with two heating rollers to successively heat the back and the front surfaces thereof and the resulting heated recording paper is guided to a paper feed roller. CONSTITUTION:In an ink jet printer for discharging recording paper 6 printed by a printing head 1 between a paper feed roller 11 and a press roller 12 contacted therewith under pressure in cooperated relation thereto, two heating rollers 20, 21 are provided between the printing head 1 and the press roller 12 while the printed recording paper 6 is brought into contact with both rollers to successively heat and dry the front and the back surfaces thereof and the heated recording paper is introduced between the paper feed roller 11 and the press roller 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device, and in particular to a recording paper feeding device for inkjet printing, in order to complete fixing at a position before the paper feeding roller, both ITs of printed recording paper are
o Let the heating roller dry it thoroughly and use a dry cloth.

II/Figure shows a previous example of a recording device, where / is a print head that carries out a printing process using a nozzle.In this example, an example of a color inkjet is shown. 9. Therefore, Fi heads are fixed to the caliper for color reference. The carriage is fitted to the guide shaft 3 so as to be freely movable, and the head feed motor gear fc1
Although it is driven laterally through the belt t'l,
During this movement, printing is performed on the recording paper 6. 7 is an ink tank that supplies ink to the nozzles (not shown) of the print head l, 8 is its supply pipe, and the head is attached to a flexible wiring board. An error print signal is supplied.

IO is maintained by the paper feed roller//ll-driven valance, and the presser roller/2 is kept in contact with the paper feed roller//, and between these rollers Recording paper 6 is held between the two. That is, the recording paper 6 wound around the paper supply roll /3 is guided under tension to the lower guide roller /j to the upper guide roller /j for printing, and is then transferred to the paper feed roll //. Presser roller/
A conductor is inserted between the holder and the holder and pulled out to the storage position.

However, due to the inconvenience caused by the recording device in C, the paper was guided between the roller L/ and the presser roller L- without fixing the printed characters, and the unfixed prints were not fixed. The roller/λ causes the ink to spread outside of the predetermined area, resulting in poor image quality. In addition, the yen adheres to the roller saw, staining the recording paper again and the paper with the recording lines, reducing the product value.

The purpose of the present invention is to eliminate the above-mentioned defects and improve the quality of printing by passing the recorded portion of the recording paper through a heating roller for a while before guiding it to the paper feed roller to fix the attached dots. It is to provide a distribution Sat that can be done with Jin.

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

FIG. 1 shows an embodiment of the present invention, in which parts similar to those in FIG. Xν1 is the heating roller 69, and X is the one that warms the upper guide roller.
The dC recording paper 6 that has been exposed to the heat roller 7 is printed with dots by the print head, and then guided to the lower surface of the heating roller 2.
Between the paper feed roller // and the presser roller saw, there is a 16° conductor.
The ink dots adhering to the top of the paper quickly begin to evaporate and dry, and are then heated by the heating roller 2/19 from the front side, so that the ink dots are completely fixed.

Therefore, even if the recording paper 4 is subsequently guided between the paper feed roller // and the presser roller saw, no ink dots will be transferred to the presser roller.

Generally, if the recording paper 6 under such tension is dried using only hot air, for example, wrinkles may occur in the vertical direction, but in this example, the roller Xs
? Since the back and front surfaces of the paper 6 are heated while in contact with the blood of the paper 6, a smooth product can be obtained without the need for this process.

Note that the other configurations are the same as the example in FIG. 1.

According to the present invention, heat is applied to the heating roller from the back side of the recording paper after printing, and then heat is applied from the front side before the recording paper is guided between the paper feed roller and the presser roller. During this process, complete fixation is achieved, and the print is no longer transferred to the press roller, thereby improving the quality of the recording.
