In the facsimile apparatus having the above-described configuration, a case where a received document or a copy document is recorded on only one side of the recording paper 2 set in the recording paper cassette 1 will be described.

When recording is performed on only one side of the recording paper 2, the switching member 11 is turned to the position indicated by the dotted line in FIG. 1 to close the third recording paper transport path t3 and perform the second recording. The paper transport passage t2 is opened. For example, when the facsimile apparatus receives and prints a received document, the recording paper 2 set in the recording paper cassette 1 is carried out by the pickup roller 3, and the recording paper 2 is transferred to the first recording paper transport path t1. And then inserted between the platen roller 5 and the thermal head 6 to perform thermal transfer printing with the ink ribbon 9. Thereafter, the recording paper on which the thermal transfer printing has been performed passes through the second recording paper transport passage t2,
The first recording paper is fed from the recording paper discharge passage t4 toward the recording paper discharge port 13 by the first recording paper feeding member 12. In this way,
The received original and the copy original are recorded on only one side of the recording paper 2.

Next, the received original and the copy original are transferred to the recording paper 2.
The case of recording on both sides will be described.

When recording on both sides of the recording paper 2, the switching member 11 is turned to the position indicated by the upper solid line in FIG. The transfer passage t3 is opened. For example, when the facsimile apparatus receives and prints a received document, the recording paper 2 set in the recording paper cassette 1 is carried out by the pickup roller 3, and the recording paper 2 is transferred to the first recording paper transport path t1. And then inserted between the platen roller 5 and the thermal head 6, and the original is thermally transferred and printed on one side of the recording paper by the ink ribbon 9. Thereafter, the recording paper on which the thermal transfer printing has been performed enters the temporary stock section 17 by the second recording paper feeding member 15 via the third recording paper transport path t3. At this time, the recording paper reversing member 16
Is in the upper standby position as shown in FIG.
c and a plate 24 facing the reversing pickup roller 16c, there is formed a gap through which the recording paper can pass.

Next, the lever 16 of the recording paper reversing member 16
b was rotated to the lower operation position, the recording paper having one side printed was sandwiched between the reversing pickup roller 16c and the plate member 24, and the printing was performed on one side by the reversing pickup roller 16c. The recording paper is again inserted between the platen roller 5 and the thermal head 6 through the fifth recording paper transport path t5 and the first recording paper transport path t1, and is then attached to the other side of the recording paper by the ink ribbon 9. Then, the original is subjected to thermal transfer printing. Thus, the temporary stock unit 17
The recording paper having one side printed thereon is transported from the temporary stock unit 17 to the thermal head 6 via the fifth recording paper transport path t5 and the first recording paper transport path t1. Since it is reversed, printing is performed on both sides of the recording paper.

After the recording paper on which one side has been printed enters the temporary stock section 17, the switching member 11 is turned to the position indicated by the dotted line in FIG. 1 to close the third recording paper transport passage t3. Then, the second recording paper transport passage t2 is opened. Therefore, recording paper with both sides printed is
The first recording paper feed member 1 passes through the second recording paper transport path t2.
2, the paper is sent from the recording paper discharge passage t4 toward the recording paper discharge port 13.

As described above, in the case of printing on both sides, the recording paper on one side printed in the temporary stock section 17 is introduced into the printing section from the rear end, so that printing is performed on the back side. In this case, it is preferable to print from the last part of the stored image data.

In the above-described embodiment, the second recording paper transport path t2 and the third recording paper transport path t3, the temporary stock unit 17, and the recording paper cassette 1 are arranged close to each other in this order. Thus, the facsimile can be downsized.

Furthermore, since the printing section is of a type in which the ink on the ink ribbon 9 is thermally transferred to the recording paper by the thermal head 6, a facsimile capable of performing double-sided printing with a compact configuration despite being a plain paper type. The device can be realized.
