Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for a communication device.

In general, a device such as a facsimile device that communicates according to a predetermined control procedure requires comparatively long pre-procedures and post-procedures before and after transmitting an image signal that is converted into an electrical signal from image information of a document to be transmitted.

For example, according to CCITT's G-standard, the pre-procedure requires about 20 seconds. During this time, since the facsimile machine itself does not move mechanically, the user is left in an uncertain state as there is no way to know whether the facsimile machine is working properly or is malfunctioning. Furthermore, the device itself has various communication modes with different processing times, and the time lengths of pre-procedures and post-procedures depending on the communication modes may not be predictable.
For this reason, even if the device is operating correctly, if the pre-steps take a long time and the transition to mechanical operation does not occur, the user may quickly suspect that the device is malfunctioning and press the emergency stop button. , it may interrupt the procedure that is in progress.

In order to prevent this drawback, conventional facsimile devices turn on (or flash) a lamp to indicate that they are "communicating" while performing the above procedure, and inform the user of the device during the pre-procedure or post-procedure. It was letting me know that it was inside. However, in the conventional method as described above, even if it is known that the pre-procedure or post-procedure is in progress, it is not possible to know whether the control procedure has just started, is in the middle of the control procedure, or is about to end. Furthermore, whether the transmitter side (the side that sends the image signal) is sending the procedure signal, or the receiver side (the side that receives the image signal) is sending the procedure signal, and what type of signal it is. It was not possible to know whether the person was sending a message or not.

Furthermore, since the lamp that indicates that the conventional device is "communicating" continues to light up even when the image signal is being transmitted, it is difficult to distinguish whether the previous procedure is being communicated or the image signal is being transmitted. Ta.

The facsimile device of the present invention eliminates the user's anxiety by displaying the progress status of the control procedure.
When an error (error during communication) occurs, the user is asked to understand the cause and make an appropriate decision (for example, whether to call the user of the other party and discuss it with him or to lower the transmission rate). It is designed to prompt users to take corrective action (should they retry the transmission?).

The present invention will be explained below with reference to the drawings.

Figures 1a and 1b are chart diagrams explaining the G-standard control means, Figure 1a shows a flowchart of the control procedure on the transmitter side, and Figure 1b shows the flowchart on the transmitter side (line L). This diagram shows the structure of the message signal output on the left side) and the receiver side (on the right side of line L). When you make a call as shown in Figure 1a, a ringing tone is transmitted to the receiver as shown in Figure 1b, and when the receiver automatically switches to facsimile reception, the receiver receives a 2100Hz signal. signal 3
Output for seconds. This signal is called CED (Call Ed).
This is called Station IDentification (called station identification signal). As a result, when the transmitter side opens the "CED", it "presses the transmit button" according to the chart in Figure 1a. Then, on the receiving side shown in Figure 1b,
Combines 1850Hz signal and 1650Hz signal and outputs the combined signal for 1.5 seconds. GI2 this signal
(G-roup identification, that is, G group recognition signal).

Next, on the transmitter side, GC2 (Group Command or G group designation signal) which outputs a 2100Hz signal for 1.5 seconds or Gcc (not shown) which outputs a 1850Hz signal for 1.4 seconds (Group Command C or C
mode group designation signal) is sent, and the GC2
After that, there is a PHASE that outputs a 2100Hz signal for 6 seconds.
(phase signal) is added. On the other hand, the receiver side
In the case of GC2, outputs a 1650Hz signal for 3 seconds.
CFR2 (ConFirmation to Receive or G
In the case of the GCC, combine the 1100Hz signal and the 2100Hz signal (group reception preparation confirmation signal),
(not shown) outputs the combined signal for 1.4 seconds.
Sends CFRC (ConFirmation to Receive C, that is, C mode reception preparation confirmation signal). The steps from GI2 to CFR2 (or CFR C) described above correspond to the "pre-message procedure" shown in Figure 1a. Then, when you move on to "message sending", Figure 1b
A picture signal "PICTURE" modulated by a 2100Hz carrier is sent out from the transmitter side (for about 180 seconds).

After sending the image signal, the transmitter side outputs a 1100Hz signal for 3 seconds (EOM2 (End Of Massage, G group message end signal) or
EOM (not shown) outputs a 1100Hz signal for 0.5 seconds
MCF2 (Massage ConFirmation or G
Group message confirmation signal) or an unillustrated MCF C (C mode message confirmation signal) that outputs a 1100Hz signal for 1.4 seconds. and,
EOM2 (or EOM C) and MCF2 (or
MCF C) corresponds to the "post-message procedure" shown in Figure 1a. If the next document is inserted within 6 seconds, the above-mentioned "pre-message procedure", "message transmission" and "post-message procedure" are repeated, but if the next document is not inserted within 6 seconds, ends the transmission. To end the transmission, the PIS (Procedure Interrupt) outputs a 462Hz signal for 3 seconds from the transmitter as shown in Figure 1b.
Sends a signal (interruption procedure signal). FIG. 2 is a block diagram of an electric circuit on the transmitter side that performs the above-described operation. In Figure 2, the signal input from telephone line 1 is the signal output by the receiver, that is, 2100Hz.

), BPF6 (for 1850Hz), BPF7 (for 1650Hz),
Each has a configuration with BPF8 (for 1100Hz).
The outputs of BPFs 5, 6, 7, and 8 are output from full-wave rectifying and shaping circuits (hereinafter referred to as shaping circuits) 9 and 1, respectively.
0, 11, 12 are connected to input signals, and the rectified signals are connected to signal lines 13a, 13b,
They are output from 13c and 13d, respectively. In FIG. 2, when switch 2 is connected to contact a side, a signal sent from a receiver (not shown) is amplified by amplifier 3 via line 1 and switch 2. For example, if the signal is the CED mentioned above,
The signal is output to the signal line 13a via the BPF5 and the rectifier circuit 9. Similarly, in the case of signal GI2, it passes through BPF6 and 7, rectifier circuits 10 and 11, and signal lines 13b and 13c, and in the case of CFR2 and MCF2, it passes through BPF7, rectifier circuit 11, and signal line 13c, and the signal of CFR C is passed through BPF7, rectifier circuit 11, and signal line 13c. In this case, BPF5, 8, rectifier circuit 9, 12, signal line 13

The display plates 16a to 16P are transparent or semitransparent (for example, diffusive) and have light emitting elements 15a to 1.
Even if it transmits or diffuses 5P light,
It may be opaque and provided near the light emitting elements 15a to 15P.

The aforementioned signal names (CED, GI2, etc.) are displayed on the display boards 16a to 16P as shown in the figure. Therefore, when the control circuit 17 receives the "CED" signal from the signal line 13a, the control circuit 17 receives the "CED" signal from the signal line 14a.
A current is applied to turn on the light emitting element 15a, and the display panel 16a is illuminated for only 3 seconds as described above. Next, when the signal "GI2" is inputted from the signal lines 13b and 13c, the control circuit 17 stops the current in the signal line 14a and flows the current in the signal line 14b, lights up the light emitting element 15b, and lights up the display board 16b by 1.5 Brighten for just a second. Next, when the input of the "GI2" signal is completed, the control circuit 17 controls the signal line 18.
