Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper recording apparatus using roll type recording paper.

[0002]

2. Description of the Related Art For example, a roll type recording paper is used as a recording device for recording an image signal received by a facsimile machine on the recording paper.

A conventional roll paper recording apparatus is shown in FIG. That is, in FIG. 5, 1 is an apparatus main body having a recording paper receiving portion 2 for rotatably receiving and supporting the roll-shaped recording paper P, and 3 is a portion between a position where the recording paper receiving portion 2 is closed and a position where the recording paper receiving portion 2 is opened. A lid member movably provided on the apparatus main body 1, a thermal head 4 provided on the lid member 3, supported on a recording paper receiving portion 2 of the apparatus main body 1 and recording on a roll-shaped recording paper P fed out, 5 Is a platen roller which is provided in the apparatus main body 1 and conveys the roll-shaped recording paper P by bringing it into contact with the thermal head 4 when the lid member 3 is in the closed position, and 6 is a recording paper receiving portion of the apparatus main body 1 inside the lid member 3. A paper retainer provided between the heat sensitive head 4 and the heat sensitive head 4.

When the roll type recording paper P is loaded in the recording apparatus, the lid member 3 is rotated to the open position to open the recording sheet receiving section 2 of the apparatus main body 1 and the roll type recording sheet P is transferred to the recording sheet receiving section 2.
Put in and support. At this time, the thermal head 4 moves together with the lid member 3 and separates from the platen roller 5. The roll-shaped recording paper P is fed out and pulled out through the upper side of the platen roller 5 to the outside of the apparatus main body 1.

After that, the lid member 3 is rotated to the closed position and locked to the apparatus main body 1. As a result, the thermal head 4 and the platen roller 5 sandwich the roll-shaped recording paper P. Then, while the platen roller 5 is rotated in the direction of the arrow in the figure to convey the roll-shaped recording paper P, the heat-sensitive head 4 records on the roll-shaped recording paper P.

The portion of the roll-shaped recording paper P supported by the recording paper receiving portion 2 is brought into sliding contact with the flat surface formed on the paper retainer 6 and reaches the thermal head 4. As a result, the "winding" of the rolled-out recording paper P is corrected so that the rolled recording paper P is brought into contact with the surface of the thermal head 4 in a flat state to perform good recording.

However, in the recording apparatus having this structure, the "winding" of the roll-shaped recording paper P on the feeding portion cannot be sufficiently corrected, and therefore, the thermal recording head 4 is in a flat state of the roll-shaped recording paper P. In some cases, good recording may not be possible without touching the surface of the.

Therefore, a recording apparatus equipped with a "winding" means shown in FIG. 6 has been conventionally used. 6, the same parts as those in FIG. 5 are designated by the same reference numerals. In this example, the member 7 and the roller 8 supported at the tip of the member 7
And a member 9 located above the roller 8 and having a recess 9a surrounding the periphery of the roller 8 are provided in the apparatus main body 1, and the feeding portion of the roll-shaped recording paper P is the roller 8 and the recess 9a of the member 9. It is designed to be moved to the heat-sensitive head 4 through the gap.

As a result, the roll-out recording paper P is bent in the process of passing it between the roller 8 and the recess 9a, so that the "roll-up" of the roll-shaped recording paper P can be made as compared with the conventional configuration. You can definitely fix it.

However, as shown in FIG.
In the recording apparatus shown in FIG.
In order to correct the above, the portion of the roll-shaped recording paper P supported by the recording paper receiving portion 2 of the apparatus body 1 is supported by the roller 8 supported by the tip of the member 7 provided in the apparatus body 1,
It is necessary to pass the member 9 provided in the apparatus main body 1 between the member 9 and the recess 9a. This work is very troublesome and time-consuming because the gap between the device body 1 and the lid member 3 in the open position is narrow and the gap between the roller 8 and the recess 9a is narrow. As a result, the work of loading the roll-shaped recording paper P is very troublesome.

The present invention has been made based on the above circumstances, and it is easy to load the roll type recording paper into the main body of the apparatus and surely correct the "winding" of the feeding portion of the roll type recording paper. It is an object of the present invention to provide a roll paper recording device capable of performing the above.

During the process in which the lid member moves to the closed position, the second operating member pushes the first operating member in the direction in which the first sheet passing guide moves away from the roll-type recording paper.

As a result, the first sheet passing guide is operated by the first operating member and swings about the rotation axis in a direction away from the roll type recording paper to pull the feeding portion of the roll type recording paper. Further, the second paper passing guide presses the feeding portion of the roll type recording paper in the direction opposite to the first paper passing guide. As a result, the feeding portion of the roll-type recording paper is supported by meandering in an S-shape by the first paper feed guide 1 and the second paper feed guide.

When the cover member reaches the closed position, the thermal head comes into contact with the platen roller. Recording is performed on the roll-type recording paper with the thermal head while rotating the platen roller to convey the roll-type recording paper.

Here, the portion fed from the roll type recording paper supported by the recording paper receiving portion of the apparatus main body is given a tension by the first paper passing guide and the second paper passing guide, and S
In the process of meandering and moving in a letter shape, the "curl" is surely corrected, and in a flat state, the thermal head is contacted and good recording is performed.

Further, when the roll type recording paper is loaded, if the lid member is moved in the direction of closing the recording paper receiving portion,
During the process in which the lid member moves to the closed position, the second operating member operates the first operating member to swing the first paper passing guide, and the first paper passing guide feeds the roll-type recording paper. While pulling the part, the second paper feed guide pushes the feeding part of the roll-type recording paper in the opposite direction to the first paper-feeding guide, and corrects the "winding" existing in the feeding part of the roll-type recording paper. In this way, the feeding part is supported by meandering with tension.

As described above, "rolling" of the roll-out recording paper is automatically corrected by a simple operation of inserting the roll-shaped recording paper into the recording-paper receiving portion of the apparatus main body and closing the lid member. It can be supported in the form. Therefore, the work of supporting the roll-type recording paper in a form that corrects the "rolling" and loading it into the main body of the apparatus can be performed very easily without requiring special work, and as a result, the roll-type recording paper can be The work of loading becomes very easy.
