First, the facsimile operation mode is specified (S l
O) When the transmission mode is designated (S11), the reading device 2 reads both sides of the document (S12), and the communication control device 5 converts the read data into predetermined transmission data and sends it to the other party. Send to facsimile machine (S13)
Here, data can be transmitted simultaneously on both sides by using a two-channel communication interface, or can be transmitted sequentially from one side at a time by using a one-channel communication interface.

Then, the above operations are performed sequentially for the set originals, and when all the originals have been sent (S14)
, ends the process.

Also, when copy mode is specified in Sll,
The reading device 2 reads both sides of the document (s is), and the recording device 3 records the read data on both sides of the recording paper (516). Note that this double-sided recording in the recording device 3 is performed at the time of reception. As described later, the first received page is treated as the younger page (front side), but in the case of copying, the front and back sides of double-sided recording are determined based on the state of the document set in the reading device 2. It has become. and,
Upon completion of copying all manuscripts (S17),
Finish the process.

Further, when receiving data, the communication control device 5 receives data from the outside (Sl8), and the controller 4 develops the received data into image data and converts it into data for recording, and then the recording device M3 Recording is performed on both sides of the recording paper (S19).

In this double-sided recording, the first page of received data is treated as the younger page, that is, the first page of received data is recorded on the front side of the first sheet of recording paper, and the second page of received data is recorded on the front side of the first sheet of recording paper. Record on the back side of the first sheet of recording paper. Furthermore, regarding the subsequent received data, odd-numbered pages are recorded on the front surface of the recording paper, and even-numbered pages are recorded on the front surface of the recording paper. This allows the received data to be automatically recorded on both sides of the recording paper without any special operations.

Then, the process ends when the reception is completed (S20).

FIG. 3 is a side view showing the configuration of the recording device 3. As shown in FIG.

This recording device is configured as a laser beam printer, and includes a paper cassette 8 in which recording paper 7 is set, a paper feed roller 9, a recording unit 10 consisting of a laser scanner, a photosensitive drum, a developer, etc., and a fixing roller. 11 and
Reversing switching section 13, reversing mechanism section 14, and paper ejection roller 40
and a paper discharge tray 41.

In this recording device, first, the recording unit 10 and the fixing roller 11 perform recording on the surface of the recording paper 7, and then the recording paper 7 guided to the paper ejection tray 41 side is reversed by the reversing drive of the paper ejection roller 40. The reversing mechanism section 1 is activated by the operation of the switching section 13.
4, the paper is again sent to the recording unit 2 10, the back side is recorded, and the paper is stacked on the paper discharge tray 41.

FIG. 4 is a schematic diagram illustrating the timing when a recording operation is performed on six pages of recording paper in such a recording apparatus.

In the figure, T1 is the time required to record one page, and T2 is the waiting time required to turn over the recording paper and start recording on the back side after finishing recording on the front side.

T3 indicates the waiting time required after the end of recording on the back side until feeding the next recording paper and starting recording on the front side.

As shown in FIG. 4, since the conveyance path of the recording paper is different when recording on the front side of the recording paper and when recording on the back side, the above-mentioned waiting times T2 and T3 are often different from each other. Therefore, in the facsimile machine of this embodiment, a cue sensor 50 is provided at the entrance of the recording unit IO, and based on this detection timing, the timing of transmitting image data from the controller 4 is controlled, and the timing of sending out image data from the controller 4 is controlled to ensure proper alignment on both the front and back sides of the recording paper. This ensures timely recording operations.

Figure i5 is a flowchart showing the operation of the facsimile machine when the present invention is implemented.

First, the facsimile machine starts receiving calls (
S21) Next, one page is received and stored in the image memory inside the controller 4 (S22), and the recording paper is fed (S23). If the paper cassette 8 is on the back side, the paper feeding operation is continued until the beginning is completed based on the output of the 0-heading sensor 50 performed by the reversing mechanism (S24.), S23-S
By the operation of 24, the image data stored in 522 is read out from the primary image memory, which always has the same timing for sending image data to the recording device, regardless of whether recording is performed on the front or back side of the recording paper. The image data is sent to the recording device according to the output timing, and the recording device records this image data (S25). When all the data is received (326), the recording paper will be ejected (S27).
, ends the reception (S28), and if there is a next page in S2[3, if the recorded side is the front side (S29), the recording paper is reversed (S30), and if it is the back side, the recording paper is ejected (S31). ), the process returns to S22 and the next page is received.

As described above, in this facsimile device, by providing the recording device with a double-sided recording function, image information can be recorded on both sides of the recording paper, and the number of recording papers can be reduced.

Furthermore, since the number of sheets of recording paper after recording is reduced, management can be facilitated when the documents are filed as received documents.

Furthermore, in this facsimile machine, the cue sensor 50
Since the image data is sent to the recording device based on the detection timing of This has the effect of reducing the cue deviation for.

In the above embodiment, both the reading device and the recording device are provided with a double-sided recording function, but even if only the recording device is provided with a double-sided processing function, sufficient effects can be obtained. Also,
Instead of one cue sensor 50, a plurality of cue sensors 50 may be used corresponding to the front and back surfaces.

Further, in the above embodiment, a recording device in which a reversing mechanism is provided in a laser printer is described, but as long as it is possible to record on both sides of recording paper, a recording format such as thermal transfer or inkjet may be used. It is also possible to perform recording from both sides without reversing the image.

Furthermore, instead of being a recording device dedicated to double-sided recording mode, the present invention may be configured as a recording device that selectively switches between single-sided recording mode and single-sided recording mode.

[Effects of the Invention] According to the present invention, the double-sided recording function of the recording apparatus allows recording to be performed on both sides of the recording paper, thereby making it possible to reduce the size of the recording paper in half compared to the case where recording is performed on one side.

Further, by reducing the number of recording sheets after recording, it is possible to easily manage the documents, for example, when they are filed as received documents in a binder or the like.

Furthermore, since a detection means for detecting the completion of preparation for starting the recording operation is provided, and image data is sent to the recording device based on this detection timing, even though the start timing of the recording operation is different on the front and back sides of the recording paper, The recording operation can be started at an appropriate timing, which has the effect of reducing cue deviations in containers.
