ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to an image recording device such as a printer, or copier, and in particular an image recording device capable of printing on both sides of paper.
With a recording device having a function of recording on both sides of recording paper, it was necessary to provide a reversing section for reversing the recording paper for altering the side of the recording paper facing the image forming section which performs the recording. The reversing section was provided at the back of, or in front of, or over the device, in the prior art.
In the prior art image recording device, a certain space had to be provided for the reversing section, so that the overall size of the device is increased.
SUMMARY OF THE INVENTION
An object of the invention is to provide a recording device which has a function of recording on both sides of recording paper, and yet which is small in size.
An image recording device according to the invention comprises:
a paper supply section;
a paper transport path along which recording paper supplied from the paper supply section is transported;
an image forming section provided on the paper transport path;
a reversing section for reversing the recording paper;
wherein
said paper supply section has a first end from which the recording paper is picked up, and a second end opposite to said first end,
said reversing section comprises:
a reversing roller rotating forward and backward, while holding recording paper which is transported from the paper transport path having passed the image forming section, and which is to be reversed, and
a reversing path in which the recording paper having passed the reversing roller is reciprocated, and which is formed at least at the second end of the paper supply section,
wherein the recording paper reversed by the reversing section is passed over the paper supply section, and guided to the paper transport path.
