Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a facsimile machine with improved operability.

(Prior Art) There are two types of facsimile communication: those that use telephone lines and those that use lines dedicated to facsimile.Facsimile communications that use telephone lines are generally carried out as follows.

When the called party (hereinafter referred to as the receiving party) is called by dialing from the calling party (hereinafter referred to as the transmitting party), the receiving party manually or automatically connects the telephone line from the telephone to the facsimile machine. Switch. This line switching is done by sending a called terminal identification signal (hereinafter referred to as CED signal) to the sending side.
will be notified as. This CED signal is an oscillation sound of a predetermined frequency, and when an operator on the transmitting side listens to this and confirms that the line has been established, he turns on the transmit button of the facsimile machine. This allows messages (image information) to be transmitted from the sending side to the receiving side.

However, in the above-mentioned conventional facsimile machine, when an operator on the transmitting side listens to the CED signal from the receiving side, there is not much of a problem if the facsimile machine is a so-called stationary type where the facsimile machine is installed nearby, but in recent years The portable facsimile machines used can be used in noisy environments.

There is a problem that it is difficult to hear the CED signal.

(Problems to be Solved by the Invention) As described above, in the above-mentioned conventional facsimile machine,
Since the CED signal has been confirmed using only the oscillating sound from the handset, there is a problem in that it is difficult to hear the oscillating sound when the facsimile machine is used in a noisy environment. For this reason, even though the CED signal was being transmitted, it could not be heard and the line remained established for a long time, resulting in additional telephone charges, which was uneconomical. .

The present invention is based on the above circumstances, and it is an object of the present invention to provide a facsimile device that can reliably notify the reception of a CED signal and eliminate the above unreasonableness.

[Means for Solving the Problems] Therefore, the present invention provides a display means for displaying a CED signal when it is received.

(Operation) The receiving side, called by the dial from the sending side, connects the facsimile device to the telephone line (line establishment) and sends out a CED signal to notify this.

On the transmitting side, when this CED signal is detected, the display means lights up to reliably notify the reception of the CED signal.

(Embodiment) Hereinafter, a preferred embodiment of the facsimile apparatus according to the present invention will be described based on the drawings.

FIG. 1 shows an embodiment of a facsimile apparatus according to the present invention together with a communication line and a receiving facsimile apparatus.

Note that this figure shows only the constituent parts of the present invention, and the image reading section and the like are omitted.

The facsimile machine 1 on the sending side includes a control unit 3 having a CPU as the control center, and a modem LS serving as a communication interface.
It is equipped with I5. In addition, particularly in this embodiment, an indicator lamp 7 composed of a light emitting diode is provided.
As will be described later, when a CED signal sent from the receiving facsimile device 17 is detected, the light turns on or blinks.

The modem LSI 5 of the facsimile machine 1 on the sending side is connected to the receiving side via a communication line 9. The receiving side device in this embodiment is illustrated as having an automatic receiving device, and when this automatic receiving device 11 receives a calling signal from the transmitting side, it switches the changeover switch 13 to the telephone 41.
After switching from the receiving facsimile machine 15 side to the receiving facsimile machine 17 side and establishing a line, the CEDI@ is sent to the transmitting facsimile machine 1.

The CED signal sent from the receiving side is a transmission signal of 210087 for 2.6 to 4 seconds as shown in FIG. (This CED signal is sent from the transmitting handset as “bee”.
It can be heard as an oscillating sound. ) Next, the operation of this embodiment will be explained with reference to the flowchart of FIG.

The flowchart in FIG. 3 shows the tonal procedure applied to analog facsimile machines (G1 machine, G2 machine). If the sending facsimile device 1 is an automatic terminal, a calling signal (hereinafter referred to as a CNG signal) is sent out (step 301). This CNG signal is a signal indicating that the transmitting terminal is a non-voice terminal. Note that if the sending facsimile device 1 is a manually operated terminal, this CNG signal is an option, so generally,
The operator dials in and calls the other party.

When a CNG signal is detected on the receiving side (step 401),
CED signal transmission is then performed as follows. That is, the automatic receiving device 11 automatically receives the CNG signal, switches the changeover switch 13 to the facsimile device 17 side, connects the facsimile device 17 to the line, and
Send a CED signal after ~2.5 seconds (step 403
).

If the receiving side is manned, the line is manually switched from the telephone 15 side to the facsimile 17 side by hearing the CNG signal or by talking with the transmitting side operator, and transmits the CED signal.

When the CED signal is sent from the receiving facsimile machine 17, this CED signal is detected by the modem LSI 5 of the transmitting facsimile machine 1 (step 303). Then, the display lamp 7 lights up to notify the operator of the reception of the CED signal (step 305). The operator confirms that the communication line has been established by seeing that the indicator lamp 7 lights up, and turns on the communication button (step 307). When the communication button is turned on, the display lamp turns off (Step 3)
09).

In this way, even when the facsimile machine 1 is used in a noisy environment, the transmitting operator is reliably notified by the lighting of the display lamp 7 that the communication line with the receiving facsimile machine 17 has been established.

Following the transmission of the CED signal, the receiving side transmits a group identification signal (referred to as a GI double signal) (step 405). This GI double signal is used to indicate the number of the facsimile group (G1, G2, G3, etc.) that can be received on the receiving side. To detect this Gl signal, step 311),
The transmitting side sends out a GO multiplication signal (a signal specifying the communication mode to be transmitted) and a transport matching signal. When the receiving side receives these GO multiplied signal transfer matching signals, it sends out a reception ready signal. As a result, from the sending side, Step 3
A message (image signal) is sent out as shown in 13.

When this is received on the receiving side (step 407), the transmission of one document sheet is completed.

Although the present embodiment has been described using a tonal procedure as an example, the present invention is not limited to this, and can of course be applied to a binary procedure facsimile apparatus δ applied to G3 machines and the like.

[Effects of the Invention] As explained above, according to the present invention, C from the receiving side is
Since a display means is provided to notify the reception of the ED signal, the CE
Even when a facsimile machine is used in a noisy environment where it is difficult to hear the D signal, it is possible to reliably know that the CED signal has been received. Therefore, the time required to confirm the reception of the CED signal is shortened, and it is possible to prevent the occurrence of a situation in which communication time is wasted.
