And a reverse pick-up roller 16c. Reference numeral 17 denotes a temporary stock portion for recording paper, which is formed between the receiving member 14 and a plate-like frame c2 arranged substantially horizontally, for temporarily stocking the recording paper. The frame c2 can also be used as a lid of the recording paper cassette 1, as shown in FIG.
[0012]
t5 is the fifth recording paper branched from the middle of the first recording paper conveyance path t1 formed between the pickup roller 3 and the thermal head 6 for taking out the recording paper 2 stored in the recording paper cassette 1 described above. It is a conveyance path, and is configured to join the third recording paper conveyance path t3 and communicate with the temporary stock unit 17.
[0013]
Reference numeral 18 denotes a document insertion port. The documents introduced from the document insertion port 18 are separated one by one by the document separation roller 19 and then passed between the platen roller 20 and the reading sensor 21. It is configured to be read by the reading sensor 21 and carried out from the document discharge port 22. Reference numeral 23 denotes an operation unit on which keys 23a and the like are arranged.
[0014]
A case will be described in which a received original or a copy original is recorded on only one side of the recording paper 2 set in the recording paper cassette 1 in the facsimile apparatus having the above-described configuration.
[0015]
When recording on only one side of the recording paper 2, the switching member 11 is turned to the position of the dotted line below in FIG. 1 to close the third recording paper conveyance path t 3 and thereby the second recording paper conveyance path. Open t2. For example, when the facsimile apparatus receives and prints the 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 passes through the first recording paper conveyance path t1. Then, it is inserted between the platen roller 5 and the thermal head 6, and thermal transfer printing is performed by the ink ribbon 9. Thereafter, the recording paper on which the thermal transfer printing has been performed is sent from the recording paper discharge path t4 toward the recording paper discharge port 13 by the first recording paper feed member 12 through the second recording paper conveyance path t2. In this way, the received document or copy document is recorded only on one side of the recording paper 2.
[0016]
Next, a case where a received document or a copy document is recorded on both sides of the recording paper 2 will be described.
[0017]
When recording on both sides of the recording paper 2, the switching member 11 is turned to the position of the upper solid line in FIG. 1 to close the second recording paper transport path t <b> 2 and the third recording paper transport path t <b> 3. Keep it open. For example, when the facsimile apparatus receives and prints the 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 passes through the first recording paper conveyance path t1. Then, the original is 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 thermal transfer printing has been performed enters the temporary stock section 17 by the second recording paper feeding member 15 through the third recording paper conveyance path t3. At this time, the lever 16b of the recording paper reversing member 16 is at the upper standby position as shown in FIG. 1, and therefore, between the reversing pickup roller 16c and the plate material 24 facing the reversing pickup roller 16c, A gap through which the recording paper can pass is formed.
[0018]
Next, the lever 16b of the recording paper reversing member 16 is rotated to the lower operating position, and the recording paper on which one side is printed is sandwiched between the reversing pickup roller 16c and the plate member 24, and the reversing pickup roller 16c. Thus, the recording sheet on which one side has been printed is inserted again between the platen roller 5 and the thermal head 6 through the fifth recording sheet conveying path t5 and the first recording sheet conveying path t1, and then the ink ribbon 9 Then, the original is thermally transferred and printed on the other side of the recording paper. In this way, the recording paper carried into the temporary stock unit 17 and printed on one side passes from the temporary stock unit 17 through the fifth recording paper conveyance path t5 and the first recording paper conveyance path t1 to the thermal head. Since it is reversed by being conveyed in six directions, printing is performed on both sides of the recording paper.
[0019]
After the recording paper on which one side is printed enters the temporary stock section 17, the switching member 11 is turned to the position of the lower dotted line in FIG. 2 Open the recording paper conveyance path t2. Accordingly, the recording paper on which both sides have been printed is sent from the recording paper discharge path t4 toward the recording paper discharge port 13 by the first recording paper feed member 12 through the second recording paper transport path t2.
[0020]
Note that, as described above, when printing on both sides, the recording paper on which one side of the temporary stock portion 17 is printed is introduced from the rear end into the printing portion. It is preferable to print from the last part of the stored image data.
[0021]
In the embodiment described above, the second recording paper transport path t2, 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. Can be made compact.
[0022]
In addition, the printing unit has a system in which the ink on the ink ribbon 9 is thermally transferred to the recording paper by the thermal head 6, so that a facsimile apparatus capable of duplex printing can be realized with a compact configuration while being a plain paper type. it can.
[0023]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be achieved.
[0024]
If necessary, the received original or copy original can be printed on both sides of the recording paper.
[0025]
Since the recording paper conveyance path branched into two, the temporary stock section, and the recording paper cassette are arranged close to each other in this order, the facsimile apparatus can be made compact.
[0026]
Since the printing unit thermally transfers the ink on the ink ribbon onto the recording paper by the thermal head, a facsimile apparatus capable of duplex printing with a compact configuration can be realized while being a plain paper type.
