In the document reading section 9a, a contact sensor 12a for reading the front surface of the document 7 is arranged above, and a contact sensor 13a for reading the back surface of the document 7 is arranged below. Also in this example, the contact sensor 12a for the front surface is connected to the contact sensor 13a for the back surface.
It is arranged at a position where the original 7 reaches first. and,
Both sides of the document 7 are read in the same manner as the operation shown in FIG.

Note that instead of using a contact sensor as the reading device,
Optical system image sensors such as lenses, mirrors, and CCDs may also be used.

FIG. 6 is a side view showing the configuration of the recording device 3.

This recording device is configured as a laser beam printer, and includes a paper cassette 108 in which recording paper 107 is set, a paper feed roller 109, a recording unit (110) consisting of a laser scanner, a photosensitive drum, a developer, etc. The roller 111, the reversal switching section 113, and the reversing mechanism section 11
4, a paper ejection roller 140, and a paper ejection tray 141.

In this recording apparatus, the double-sided recording mode allows the recording paper to be
7. Recording is performed on both sides of the paper. In other words, in this double-sided recording mode, first, the recording unit 110 and the fixing roller 111 record on the surface of the recording paper 107, and then the recording paper 7 guided to the paper ejection tray 141 side is reversed by the paper ejection roller 140. It is guided to the reversing mechanism section 114 by the operation of the drive and reversing switching section 113, and is again transferred to the recording unit 110.
The paper is sent to the paper output tray 141, the back side is recorded, and the paper is stacked on the paper discharge tray 141.

Further, FIG. 7 is a plan view showing the configuration of the operation section of the facsimile machine M1.

This operation section 15 includes one display section 16. A numeric keypad 17, a dial key 18, a start key 19, and an inquiry key 20 are provided.

Among these, the timing key 20 determines whether the facsimile device of the communication partner has a double-sided reading function or a double-sided recording function, and if it has such a double-sided function.
This is used to inquire of the other party whether or not the mode is set to execute this double-sided processing.

FIG. 8 is a flowchart showing such an adjustment procedure.

First, press the 1-timing key 20 (341), then input the number of the other party's facsimile machine using the numeric keypad 17 (S42), confirm that the entered number is correct (343), and press the start key 19. As a result, (S44), the software for making arrangements is activated (545),
The processing function and setting mode of the other party's facsimile device are displayed on the display unit 16 (346).

Next, the software for making arrangements in step 345 will be explained.

FIG. 9 is a schematic diagram showing an example of an arrangement procedure in G3 facsimile.

In the figure, NSF and NSS are signals that convey non-standard functions to the other party's facsimile machine. That is, in the information field of these signals, as shown in FIG. 10, the first and second octets are codes of CCITT members, and the third octet is codes of domestic manufacturers.
The fourth octet and subsequent octets are free areas. Therefore, a duplex function identifier code indicating the presence or absence of the one-sided duplex function and a mode identifier code indicating the mode when the duplex function is provided are set in this free area. For example, as shown in FIGS. 11 (1) and (2), when the duplex function identifier code is "1", it is specified that there is a duplex function, and when it is rOJ, it is specified that there is no duplex function. Further, when the mode identifier code is "1", it is defined as a single-sided mode, and when the mode identifier code is "0", it is defined as a single-sided mode.

For example, if the sending side requests double-sided recording, when the received NSF has a double-sided recording function and indicates single-sided mode, the NSS is instructed to record in double-sided mode (duplex unit identifier code = 1, The mode identifier code = 1) is loaded and transmitted.

As shown in FIG. 12, a method for specifying the recording mode of the other party's facsimile machine is to provide a other party's mode instruction switch 25 in the same manner as the resolution instruction switch 23, density instruction switch 24, etc. The above-mentioned NSS identifier code can be switched by the operation. In addition, each instruction switch 23 to 25
Two LED indicator lights 27 to 32 are provided corresponding to each of the modes, and the desired mode is set while observing the lighting status of the indicator lights 31 and 32 depending on the pressing status of the other party's mode indicating switch 25.

By the way, if it is determined during communication that the sending facsimile device has a double-sided reading function and the receiving facsimile device has a double-sided recording function, it is difficult to determine whether the sending side will send the image in duplex or single-sided mode. to the receiving side,
If the receiving side switches between double-sided/single-sided recording mode based on this, it becomes possible to receive data in the state desired by the transmitting side.

Note that, although the above embodiments have been described using a G3 facsimile as an example, the present invention can be similarly applied to a G4 facsimile.

Further, FIG. 13 is a schematic diagram showing an example of an inquiry procedure in G4 facsimile.

In this case, the session layer receives R55P (session start response) which sends C55 (session start command). Figure 14 (1) and (2)
), as shown in figure 0, which shows the configuration of C5S and R35P, R55P includes characteristic information of the other party's terminal, and from the double-sided function identifier code and mode identifier code of the non-standard terminal functions, the receiving facsimile device Identifies whether or not the device has a duplex function, and if it has a duplex function, the setting mode. Specifically, Fig. 15 (1) and (
As shown in 2), when the duplex function identifier code is "OO", it is determined that there is no duplex recording function, and when it is roll, it is determined that the duplex recording function is present.

Note that designation of the recording mode for the other party's facsimile device can be performed in the same manner as in the case of the G3 facsimile described above.

Alternatively, the configuration may be such that the receiving side ignores instructions from the transmitting side and performs recording in the same mode.

FIG. 16 is a flowchart showing the operation of the receiving facsimile machine in this case.

First, the above-mentioned duplex/single-sided mode instruction is received from the sending side (351), and it is determined whether or not to switch the recording mode according to this instruction (S52). The processing mode is determined by referring to the setting of this mode setting switch.

If you ignore the sender's instructions, do not switch between duplex/single-sided mode and record in the same mode.Also, if you ignore the sender's instructions to switch between duplex/single-sided mode, the sender's instructions If is in double-sided mode (S53)
, the double-sided recording mode is set (S554); on the other hand, if it is the single-sided mode, the single-sided recording mode is set (S55) and recording is performed.

Further, the above-mentioned instruction to switch between duplex/single-sided mode from the transmitting side is possible even when the transmitting side does not have a duplex function. This is made possible by providing a partner mode indicating switch as shown in FIG. 12, for example.

Further, it is also possible to instruct the switching between duplex/single-sided mode from the transmitting side as described above for each page of the transmitted document. That is, in this case, mode instruction information is transmitted between pages of image information, and the receiver switches between duplex/single-sided mode in accordance with this.

FIGS. 17(1) and (2) are flowcharts showing the operation when switching between duplex/single-sided mode on a page-by-page basis; FIG. 17(1) is the operation on the sending side, and FIG. 17(2) is
indicates the operation on the receiving side.

On the transmitting side, after transmitting the mode instruction information (561),
If the image information for one page is to be transmitted (562), and the transmission is not completed (S83), the setting of the mode instruction information is changed as necessary (S64), and the process returns to 561 to transmit the mode instruction information.

Also, on the receiving side, the mode instruction information should be received (571).
, the mode is switched based on this mode instruction information (
In accordance with this, one page of image information is received (573), and if the reception is not completed (S74), the process returns to 571 to receive mode instruction information.

FIG. 18 is a schematic diagram showing a specific example of mode instruction information.

This mote instruction information includes a double-sided/single-sided identifier provided in the user reader pull comment area in the page descriptor of the presentation layer.

In the example shown in FIG. 17, the mode instruction information is transmitted for each page regardless of whether or not the mode is changed, but the mode instruction information may be transmitted only when the mode is changed.

[Effects of the Invention] According to the present invention, when the other party's facsimile device has a double-sided reading function or a double-sided recording function, the sending side can instruct the receiving side to perform processing using the double-sided function. The received information can be recorded on both sides of the recording paper, which saves half the amount of recording paper compared to recording on one side, and reduces the number of sheets of recording paper after recording by 2.
The number of sheets can be reduced to 1/2, and management as a document can be made easier by reducing the number of sheets.
