The present invention relates to a facsimile using thermal recording paper, and in particular, to prevent thermal curling of the thermal recording paper before and after the printing operation. The present invention relates to a device for preventing curling of thermal recording paper.

It is already known that with the rapid development of the communication field, the spread of communication devices such as facsimile has also spread to general households.

On the other hand, a communication device such as a facsimile is provided with a printing apparatus for reading and printing received, such a printing apparatus requires a paper for printing the received information.

In addition, the thermal recording paper is used so that a large amount of information can be directly printed on the printing paper in consideration of the amount of the received information.

However, when the thermal recording paper is used in the printing apparatus, the problem of frequent replacement of the paper has been solved by using the thermal recording paper wound many times. However, when the printed thermal recording paper is taken out from the printing apparatus, the thermal recording paper is printed. Since it was previously rolled in close contact with the roll, the phenomenon of being rolled back to the original state occurs.

In this regard, a schematic diagram showing a device for unfolding a thermal recording paper during a printing operation in a conventional printing apparatus which shows the flow of the thermal recording paper in a printing apparatus commonly used in this field is shown in FIGS. 1 (a) and (b). Shown.

(A) of FIG. 1 is a schematic diagram which shows the state in which a thermal recording paper is wound many times, and (b) of FIG. 1 is a schematic diagram which shows the state in which a thermal recording paper is wound around generally.

As shown in (a) and (b) of FIG. 1, the configuration of the printing apparatus includes a thermal recording paper 46 on which a heat-sensitive liquid is applied to an outer surface 46a, and a thermal recording paper 46 on a roll 45. A recording tray 47 for holding and supporting the paper, a paper guide 43 for guiding and guiding the thermal recording paper 46, a platen roller 41 driven by the roller shaft 40, and a thermal sensing unit as a printing unit. A recording head 42 (TPH), a spring 49 for pressing the thermal recording head 42 (TPH) at a constant pressure, and a guide support 44 for supporting the paper guide 43. It is done.

According to the above configuration, when the platen roller 41 of the roller shaft 40 is rotated in the arrow direction (counterclockwise direction) in Fig. 1A, the thermal recording paper 46 on the roll 45 is in the arrow direction. The thermal recording paper 46 is released from the roll 45 while rotating in the counterclockwise direction.

At this time, the lower portion of the paper guide 45 located in the guide groove 48 formed in the recording tray 47 is moved while the thermal recording paper 46 is guided in a curved shape to be unfolded.

That is, when the thermal recording paper 46 wound around the roll 45 is unwound, the roll 45 is rolled up, but as the paper guide 43 passes, the curl occurs as opposed to the initial curled state. When supplied between the platen roller 41 and the thermal recording head 42 (TPH), the platen moves in an unfolded state.

Then, after a predetermined printing operation is performed on the thermal recording head 42 (TPH), the constant pressure of the spring 49 provided at the upper end of the thermal recording head 42 (TPH) and rotation of the platen roller 41 are rotated. The thermal recording paper 46 is out of the printing apparatus in an open state.

However, in order to prevent the curling of the thermal recording paper with the above-described configuration, a problem arises in that the size of the apparatus set is increased because a recording paper curl prevention plate having a shape corresponding to each other is provided between the thermal recording head and the thermal recording paper. Furthermore, it is mechanically applicable if the lower anti-roll plate is installed on the frame so as to correspond with the upper anti-roll plate, so that if the anti-roll plate cannot be installed in a corresponding position, that is, the frame is discharged in the direction of ejecting the thermal recording paper. This application is not possible unless the structure is formed. Therefore, a constraint arises from a design point of view.

Furthermore, when the printing process is performed to print the received contents, the platen roller is rotated in reverse to print on the thermal recording paper at the front of the thermal recording paper, that is, at the front of the recording head. Jams in thermal recording paper occur.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a facsimile machine with a compact device set by lowering the storage space of the thermal recording paper and replacing the upper and lower curl plates with curl bars. It is.
