Abstract

PURPOSE:To realize polling function without destorying a control sequence of the G1 and G2 standards and the format of a control signal, by replacing the operation of a calling side and a called side. CONSTITUTION:When a GI signal from a called side is confirmed at polling at a calling side, a polling reception switch other than a normal reception switch is closed. Thus, no GC signal is transmitted at the reception like automatic reception and the GI signal is transmitted to a called side. Since the called side receives the GI signal from the caller side, the called side judges itself as the transmission side, and after the transmission of the GI signal, the GC signal and a phase signal are transmitted to the caller side through the reception of the GI signal. Thus, the operation of the caller and the called side is just replaced, and a picture signal transmitted from the called side is received at the caller side and polling is attained.

称されるものがある。As one communication mode of the 7-axis device, the calling side makes a call to the called side, and the called side automatically sends a preset document, which is then received by the calling side. There is something called action.

行なわれるよう罠なっている。For such polling operations, CCITT's G3 standard facsimile machines are equipped with special control signals and control sequences, and are configured to perform polling communications in accordance with these.

。However, in the G1 and G2 standards of C(4τT), a control sequence is provided for automatic reception in which the called party receives the transmitted document from the calling party unattended, but the polling function is not supported. Not specified at all.

Switch the line to the fax machine. At the same time, the called party sends a G (Group Information) signal to the calling party indicating its own capabilities (that is, whether it is a G1 aircraft or a 02 aircraft).

A CFR (confirmation-to-receive) signal indicating that the caller is waiting for reception 111 is sent to the calling party.

Ｃ信号を送出せず、Ｇｌ信号を被呼側に送出する。In Figure 2, the operation from the calling party placing a call to the called party until the calling party detects the aX signal is the same as in the case of automatic reception in Figure 1. In the case of a polling operation, the calling side turns on a polling reception switch different from the normal reception switch when it confirms the ()I signal from the called side. This switch controls the receiving circuit in the facsimile machine in the same way as when a normal receiving switch is turned on, but differs in the following points. In other words, when the polling reception switch is turned on, the KG
A Gl signal is sent to the called party without sending a C signal.

After sending the I signal, a GC signal from the calling side is expected. However, in this case, since the Gxl signal is received from the calling side, it is determined that it is the sending side, and the Gxl signal is received from the calling side.

位相信号を送出する場合の動作に対応する。Upon receiving the I signal, it sends a GC signal and a phase signal to the calling party. This corresponds to the operation in the case of FIG. 1 described above, when the calling side sends out the CkC signal and the phase signal by turning on the transmission switch.

。Therefore, from now on, as can be seen from the comparison between Figures 1 and 2, the calling side and called side φ operations in Figure 1 are exactly interchanged,
As a result, the image signal transmitted from the called party is received by the calling party, and the polling operation is completed.
