Has been planned. For example, Japanese Patent Laid-Open No. 3-2099
It is No. 70 "facsimile machine".

FIG. 9 to FIG. 11 are diagrams showing an example of a conveyance path and a result of transmission / double-sided reception in a conventional facsimile apparatus capable of double-sided transmission / double-sided reception. In FIG. 9, a facsimile apparatus 101 includes a transmission hopper 102 on which an original for transmission is placed, a receiving hopper 104 for storing sheets for recording received contents, a stacker 106 for ejecting and storing sheets for received printing, and a transmission original. It has a reading unit 107 for reading the contents of the above and a printing unit 108 for printing the received contents.

These parts are connected to a transmission conveyance path 111, a central conveyance path 112, a reverse conveyance path 113, an upper conveyance path 114,
The carry-out carrying path 115 and the receiving carrying path 116 are connected.
Further, in front of the reading unit 107 and the printing unit 108, front end sensors 125 and 126 for monitoring a sheet (original or received recording sheet) are provided. Further, it has discharge sensors 127 and 128 for monitoring the discharge of the paper. Further, it has gates 133 and 136 for allocating the delivery destination of the paper.
In addition, it has a carrying roller for carrying out a sheet (not shown).

Next, the operation of the above conventional example will be described. First, the operation of transmitting a double-sided original will be described. A double-sided original is set in the transmission hopper 102, transmission of a double-sided original is selected from an operation unit (not shown), and the transmission key is pressed to start the transmission operation. The document is conveyed along the transmission conveyance path 111 toward the reading unit 107. When the leading edge sensor 125 detects the leading edge of the document, the reading unit 107 starts reading the content on the surface of the document. After the reading is completed, the leading edge sensor 125 detects the trailing edge of the document, and after a lapse of a predetermined time t1, the conveyance roller is rotated in the reverse direction. Due to this reversal, the original is sent on the transmission conveyance path 111
Is conveyed in the opposite direction to the branch gate 133.

The above document is conveyed toward the central conveying path 112 by the branch gate 133, and the leading edge sensor 125 is used.
After the detection of the leading edge of the document, a predetermined time t2 elapses, and then the conveyance roller is rotated in the reverse direction again. By reversing the original again, the original is conveyed to the reverse conveying path 113 by the branch gate 133 and once discharged to the outside. However, the original is again guided to the transmission conveyance path 111 by the reverse rotation operation of the conveyance roller again.
By this procedure, the reversal of the document is completed.

The original is conveyed to the reading section 107 at the same time when the front side is read, and the contents on the back side are read. When the reading is completed, the document is conveyed as it is and discharged to the outside of the apparatus. At the time of discharging the original, when the discharge sensor 127 detects the rear end (the front end when viewed from the surface) of the original, the next original is sent from the transmission hopper 102, the same operation is performed, and the reading of the double-sided original is continued. FIG. 1 shows the output result when the transmission data of the two-sided document based on the above operation is received by the facsimile apparatus which can output the reception content only on one side.
0 is shown. In FIG. 10, (A) is a plan view of a transmission original of this machine, and (B) is a plan view of the reception output of another machine.

Next, the operation of double-sided printing (double-sided recording) of received contents will be described. Paper (recording paper) for recording the received contents is set in the receiving hopper 104 in advance. When there is a reception and it is necessary to record the content, the recording paper is unwound from the reception hopper 104, passes through the reception conveyance path 116, merges with the central conveyance path 112, and is conveyed to the printing unit 108. When the leading edge sensor 126 detects the leading edge of the recording paper,
The printing unit starts printing the received contents on the surface of the recording paper.
Upon completion of printing, the recording paper is conveyed to the upper conveyance path 114 and the transmission conveyance path 111 until the leading edge sensor 125 detects the trailing edge of the recording paper. When the leading edge sensor 125 detects the trailing edge of the recording sheet, the conveying roller rotates in the reverse direction after a certain time t3 and conveys the recording sheet toward the branch gate 133.

The recording paper is conveyed to the central conveyance path 112 by the branch gate 133. With this, the front and back of the recording paper are reversed. The reversed recording paper is conveyed again to the printing unit 108, and the received content is printed on the back surface, as in the case of printing on the front surface. The recording sheet on which printing has been completed passes through the discharge transport path 115 and is discharged to the reception stacker 105. When ejecting recording paper,
When the discharge sensor 128 detects the trailing edge of the recording sheet (the leading edge when viewed from the surface), the next recording sheet is sent out from the receiving hopper 104, the same operation is performed, and double-sided recording is continued. FIG. 11 shows the contents transmitted from the one-sided transmission-only facsimile, that is, the results received and recorded by the above operation.
In FIG. 11, (A) is a plan view of a document transmitted by another device,
FIG. 6B is a plan view of the reception output of this device.

However, the above-mentioned conventional example involves the following problems. A first problem is that when a two-sided original is transmitted, the print result on the receiving side is output upside down on odd-numbered pages and even-numbered pages (FIG. 10).
(B)). The print result on the receiving side is difficult to read, and in order to make it easy to read, for example, it is necessary to arrange the upper and lower parts and arrange them. The reason for this is that the front and back of the document are reversed by vertical document switchback, and the contents of the front side are read from the front side of the document and the contents of the back side are read from the rear side.

A second problem is that when the received content is recorded on both sides, the recorded content on the front side and the recorded content on the back side are printed upside down as shown in FIG. 11 (B). Therefore, the recording form is very difficult to read. The reason is that the front and back of the recording paper are reversed by the switchback of the recording paper in the vertical direction.

It is an object of the present invention to provide a facsimile apparatus capable of reading the contents from the front end of the original on both the front and back sides when transmitting a double-sided original.

[0013]

In order to achieve the above object, the facsimile apparatus of the present invention has a configuration in which the upper transport path, the central transport path, and the lower transport path correspond to the upper, middle, and lower S-shaped sections. It has a first transport path that is continuously connected and a second transport path in which an upper transport path and a lower transport path are connected in a U shape, and displays an image of one side of a predetermined document. After the document is transported on the first transport path for reading, the document is transported to the upper transport path on the second transport path to invert the upper and lower surfaces of the document, and the other surface of the document is transported on the first transport path. The feature is that the image of can be read.

Further, the above-mentioned second conveying path is formed in a direction perpendicular to the first conveying path, and the facsimile apparatus has a hopper for placing a document, and when one side is read. Supplies an original from the hopper and provides an image reading unit for reading the image of the original between the upper conveyance path and the central conveyance path,

The document content is read by the reading unit 7, and the sorting gate 32
Is discharged to the transmission stacker 3. The reading timing and the function of each sensor are the same as those in the first embodiment. While the single-sided original is performing the transmission operation (at the same time as the single-sided original transmission operation), the recording paper is passed from the reception hopper 4 or 5 through the reception conveyance path 16 and is guided to the print conveyance path 17 by the sorting gate 34, and the printing unit At 8, the received contents are printed on one side of the recording paper.

The recording paper on which printing has been performed is sorted by a sorting gate 36.
Is guided to the upper conveyance path 15 by the upper conveyance path 1 as it is.
It is discharged to the receiving stacker 6 through the number 5. Next, parallel processing of single-sided original transmission / double-sided original transmission will be described. During the single-sided original transmission, the recording paper passes from the receiving hopper 4 or 5 through the receiving / conveying path 16, and the distribution gate 34 causes the recording / conveying path 1
Then, the printing section 8 prints the received contents on the surface of the recording paper. The transmission operation has been described above. The printed recording paper is sorted by the sorting gate 3.
It is guided to the upper conveyance path 15 by 6 and conveyed to the tip sensor 23.

When the leading edge sensor 23 detects the leading edge of the recording paper, it changes the feeding direction and feeds it to the relay feeding path 19. The recording paper is conveyed to the lower conveyance path 13 through the relay conveyance path 19,
The conveying direction is changed again, and the lower conveying path 13 guides the particles to the auxiliary relay conveying path 18 by the sorting gate 35. The recording paper is again guided from the auxiliary relay conveyance path 18 to the print conveyance path 17 by the sorting gate 33. The received content is printed on the back side by the printing unit 8 through the print conveyance path 17. The printed recording paper passes through the print conveyance path 17, is guided to the upper conveyance path 15 by the sorting gate 36, and is directly as it is.
And is discharged to the reception stacker 6. The printing timing and the function of each sensor are the same as those in the first embodiment.

Next, the parallel processing of double-sided original transmission / single-sided reception printing will be described. The double-sided original set in the transmission hopper 2 passes through the transmission conveyance path 11 by pressing the transmission key,
The reading unit 7 reads the content of the surface of the document, and the sorting gate 32 guides it to the central conveyance path 12. The document passes through the central transport path 12 and is guided to the lower transport path 13 by the sorting gate 35, and is transported until the leading edge sensor 21 detects the leading edge of the document. When the leading edge of the document is detected, the transportation is temporarily stopped.

Here, the recording sheets for single-sided reception printing which are operating in parallel are carried out to the reception stacker 6, and the printing conveyance path 1
7. Confirm that there is no recording paper in the upper transport path 15. This confirmation can be performed by checking whether or not the recording paper is detected by the leading edge sensors 23, 26 and the lateral edge sensor 24.

When it is confirmed that there is no recording paper in the transport path, the original is transported to the upper transport path 15 through the relay transport path 14 while changing the transport direction. The conveying direction is changed again, and the upper conveying path 15 guides the signal to the transmission conveying path 11 by the sorting gates 36 and 31. When it is confirmed that the original has been conveyed from the upper conveyance path 15, the next recording sheet is fed out from the reception hopper 4 or 5 and the received contents are printed.

The original passes through the transmission conveyance path 11, the contents of the back side of the original are read by the reading unit 7, and the sorting gate 32 is used.
Is discharged to the transmission stacker 3. The operation of single-sided reception printing has already been described.

Next, the parallel processing of double-sided original transmission / double-sided reception printing will be described. The transport path for the originals and recording sheets, the operation for transmitting the double-sided original, and the operation for double-sided reception printing have been described. However, during the parallel processing operation of the two-sided document transmission and the two-sided reception printing, the following operation is newly added to perform the parallel processing.

First, since the document is turned upside down, it is transported to the lower transport path 13. In this conveyance, the tip sensor 21
Detects the leading edge of the document and the feeding is paused. At this time, if the recording paper is not in the temporary stop position of the upper conveyance path 15,
The document remains in the pause position until the recording paper reaches the pause position.

In the above operation, when the recording sheet is present at the temporary stop position when the recording sheet is being conveyed to the temporary stop position, it is possible to determine whether the leading edge sensor 23 detects the leading edge of the recording sheet. .

When the recording paper reaches the temporary stop position and is temporarily stopped, the original and the recording paper are simultaneously transferred, and the original is transferred by the relay conveyance path 14.
To the upper conveyance path 15, and the recording paper starts to be conveyed from the relay conveyance path 19 to the lower conveyance path 13. The document and the recording paper are conveyed to the temporary stop positions of the upper conveyance path 15 and the lower conveyance path 13. As described above, the temporary stop position is the position stored by the lateral edge sensors 22 and 24 when the front and back are reversed.

When the temporary stop position is reached, the conveyance is temporarily stopped and the conveyance direction is changed, the original is conveyed from the upper conveyance path 15 to the transmission conveyance path 11, the recording paper is conveyed from the lower conveyance path 15 to the auxiliary relay conveyance path 18, Continue the operation of original transmission and duplex printing. On the contrary, when the recording paper is conveyed to the upper conveyance path 15 because the recording paper is turned upside down and the leading edge sensor 23 detects the leading end of the recording paper and the conveyance is temporarily stopped, the original document is conveyed to the lower conveyance path 1.
When the recording paper is not at the temporary stop position of 3, the recording paper is stopped at the temporary stop position and the original is stopped at the temporary stop position, respectively.

When the original reaches the temporary stop position and is temporarily stopped, the original and the recording paper are simultaneously transferred from the relay conveyance path 14 to the upper conveyance path 15 and the recording paper is transferred from the relay conveyance path 19 to the lower conveyance path 13. Start transportation. After that, the same operation as described above is performed, and double-sided original transmission / double-sided reception printing is performed.

According to the above-described embodiment, the document or recording sheet is turned upside down in the lateral direction of the document or recording sheet. Therefore, the orientation of the leading edge of the document or the recording paper does not reverse as in the case of reversing the front and back in the vertical direction. Therefore, even if the surface of the original or the recording paper is turned upside down, the direction of the front end is the same, and the original can be read at the time of transmission and the received contents can be printed on the front and back sides from the same direction.

The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention.
