Effects and effects of the present invention having the above-described configuration are as follows.

When printing by the digital printing machine, the media 150 is fixed to the first paper feed roller 102, and one end of the media 150 is placed on the second paper feed roller 104 installed on the rear side of the fixing frame 130. Take it away in the direction.

One end of the media 150 installed as described above is passed down to the first horizontal holding roller 106 installed in the guide frame 140 formed in the lower portion of the fixed frame 130 to pass downward, and then the base (120) Printing is started by sandwiching between the base 120 and the head portion 1 25 so as to pass through the upper portion.

The media 150 printed in this way passes down the front of the base 130 and passes downward to the second horizontal maintenance roller 108 installed at the lower front of the leg 100, and then to the front side of the fixing frame 130 again. The process is completed by being wound upwards on the installed sense roller 110.

Since the second paper feed roller 104 is formed with a non-slip member 105 made of a material having a large coefficient of friction for preventing slip along the outer circumferential surface thereof, the media 150 may be formed at the first paper feed roller 102. When moving to the second paper feed roller 104 is not slipped by the friction force, thereby eliminating the distortion phenomenon.

And, the media 150, which has been moved from the second paper feed roller 104, moves to the upper portion of the base 130, and the first horizontal maintenance roller 106 is installed in the middle thereof, and the ringing or warping of the media 150 is caused. It prevents the phenomenon.
