FIG. 1 is a block diagram of an image transmission system using a facsimile apparatus according to the present invention. A facsimile apparatus 1A and a facsimile apparatus 1B having the same configuration are connected via a public network 2. 1 shows the configuration. In the following description, the facsimile apparatus 1A will be described as a transmitting facsimile apparatus, and the facsimile apparatus 1B will be described as a receiving facsimile apparatus. Of course, the relationship between transmission and reception may be reversed.

The facsimile apparatuses 1A and 1B have a CPU 11 for controlling transmission and reception, a ROM 12 for storing a control program and the like, and an RA functioning as a working memory.
M13, an operation unit 14 having various function buttons such as a dial button and a transmission image quality button, a communication unit 15 connected to the public network 2, an image memory 16 storing image information to be transmitted or received image information, and reading a document to be transmitted. It has a reading unit 17 for converting image information, a recording unit 18 for printing out received image information, and a display processing unit 19 for adding a request / other-than-request mark to the received image information.

Next, with reference to the sequence diagram shown in FIG. 2, two originals are transmitted from the facsimile machine 1A on the transmitting side to the facsimile machine 1B on the receiving side at a linear density required by the facsimile machine 1B on the receiving side. The operation in this case will be described.

First, a line density is set as reception request information by the operation unit 14 of the facsimile machine 1B on the reception side (step S1). Examples of the line density that can be set include R8 × 7.7 lines / mm and R8 × 15.4 lines / mm.
mm, R16 × 15.4 lines / mm.

R8 means that horizontal 1 mm is divided into eight and transmitted, and 7.7 lines / mm means that vertical 1 mm is divided into 7.7 lines and transmitted. Therefore, the larger the numerical value, the higher the linear density. The line density in the standard mode is R8 × 3.85 lines /
mm.

Next, when the dial number of the other party is input from the operation unit 14 of the facsimile machine 1A on the transmitting side and the start button is pressed, a call is set and a line is established.
NG (calling tone) is transmitted (step S
2).

Next, a CED (called terminal identification signal) is transmitted from the facsimile machine 1B on the receiving side (step S).
3) In addition, NSF (non-standard function identification signal), CSI
(Called terminal identification signal), DIS (Digital identification signal)
Are transmitted in this order (step S4). The line density data set in step S1 is transmitted as reception request information by the NSF.

Next, TSI (transmission terminal identification signal) and NSS (non-standard function setting signal) are transmitted from the facsimile machine 1A on the transmission side (step S5).
(Training check signal) is transmitted (step S6). A response is sent by the NSS as to whether to transmit at a line density according to the reception request information.

If the training result is normal, a response signal C indicating that the message transmission may be started.
An FR (reception preparation confirmation signal) is transmitted from the facsimile machine 1B on the receiving side (step S7).

When the transmitting facsimile machine 1A receives the CFR, the original of the first page is transmitted to the message PIX.
It is transmitted as (1) (step S8). When the transmission of the original of the first page is completed, an MPS (multi-page signal) indicating the end of the page is transmitted (step S9).

When the facsimile machine 1B on the receiving side receives the MPS, M indicates that the message has been completely received.
A CF (message confirmation signal) is transmitted to the facsimile machine 1A on the transmission side (step S10). When the facsimile machine 1A on the transmitting side receives the MCF, it transmits the document of the second page as a message PIX (2) (step S11).

When the transmission of the document of the second page is completed, the facsimile machine 1A on the transmission side transmits an EOP (procedure end signal) because there is no other transmission page (step S1).
2). Upon receiving the EOP, the facsimile machine 1B on the receiving side transmits an MCF indicating that the message has been completely received (step S13). Upon receiving the MCF, the facsimile machine 1A on the transmission side receives DCN (disconnection command signal).
Is transmitted (step S14), and the communication is terminated.

Next, in the above-described sequence, the details of the procedure for transmitting a document in the facsimile machine 1A on the transmitting side will be described with reference to the flowchart shown in FIG.

First, an original is set on the reading unit 17 (step T1), a dial number of the other party is input by the operation unit 14, and when the start button is pressed, the original is read and stored in the image memory 16, and a call is made. Is set and a line is established (step T2).

Next, reception request information is received by an NSF (non-standard function identification signal) sent from the facsimile machine 1B on the reception side, and the request is, for example, a fine line density transmission request for requesting transmission at a fine line density. If so (step T3), the facsimile machine 1A on the transmitting side determines whether or not it is capable of satisfying the request (step T4).

If the facsimile machine 1A on the transmitting side has the ability to satisfy the request, an NSS (non-standard function setting) indicates that the original is to be transmitted at the requested linear density (for example, R16 × 15.4 lines / mm). Signal), and transmits the image information stored in the image memory 16 from the communication unit 15 to the ITU.
-Transmission is performed according to the procedure of the T recommendation (T.30 / T.4 / T.6) (step T5).

If there is no reception request information from the facsimile machine 1B on the receiving side (step T3) or if the facsimile machine 1A on the transmitting side does not have the ability to satisfy the request (step T4), the linear density in the standard mode is used as in the conventional case. Alternatively, the NSS replies that transmission is performed at the linear density closest to the request, and the image information stored in the image memory 16 is transmitted to the communication unit 15.
The transmission is performed according to the procedure of the ITU-T recommendation (T.30 / T.4 / T.6) (step T6).

Next, in the above-described sequence, the details of the procedure for receiving a document in the facsimile machine 1B on the receiving side will be described with reference to the flowchart shown in FIG.

First, the C of the receiving facsimile machine 1B
The PU 11 determines whether reception request information has been input from the operation unit 14. For example, when a request to transmit at a fine line density is input (step U1), the line density (for example, R16 × 15.4) input as the reception request information is input.
(Line / mm) is stored in the RAM 13 (step U
2).

Next, upon receiving a call from the facsimile machine 1A on the transmitting side (step U3), the CPU 11 of the facsimile machine 1B on the receiving side transmits the previously set reception request information by NSF (non-standard function identification signal). (Step U4).

Next, the CPU 11 of the facsimile machine 1B on the receiving side transmits the NS message from the facsimile machine 1A on the transmitting side.
It is determined whether or not the image information has been sent at the required linear density by S (non-standard function setting signal) (step U5).

That is, the facsimile machine 1A on the transmitting side
From the communication unit 15 to the ITU-T recommendation (T.30 / T.4 / T.6)
And records it in the image memory 16.

As a result, if the line density is as required, a request mark is added by the display processing unit 19 (step U6). If not, a mark other than requested is added by the display processing unit 19 (step U6). U7), and each is output from the recording unit 18. The request mark and the non-request mark are printed, for example, with a small linear density (for example, R16 × 15.4 lines / mm) on the upper right of the document.

If the input for transmitting at the fine linear density is not made from the operation unit 14 (step U1), the request for transmitting at the fine linear density is released (step U8), and the receiving process is performed as usual. (Step S9), and ends.

That is, the facsimile machine 1A on the transmitting side
Transmits at the optimum line density based on the line density in the standard mode or the receiving capability of the receiving-side facsimile device 1B and its own transmitting capability, and the receiving-side facsimile device 1B performs reception processing.

In the above-described embodiment, the line density has been described as an example of the reception request information requested from the reception-side facsimile apparatus 1B to the transmission-side facsimile apparatus 1A, but the present invention is not limited to this. Transmission speed, paper size, etc. can also be transmitted as reception request information.

[0036]

As described above, according to the present invention, reception request information specifying transmission conditions is transmitted from the reception-side facsimile apparatus to the transmission-side facsimile apparatus, and the transmission-side apparatus follows the reception request information. Since transmission is performed under the above-described transmission conditions, the receiving-side apparatus has an advantageous effect that it can receive image information of desired quality.
