Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile 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 apparatus itself has various communication modes with different processing times, and the length of time for each pre-procedure and post-procedure depending on the communication mode 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 user anxiety by displaying the progress status of the control procedure,
When an error (communication error) occurs, the user can be informed of the cause and make an appropriate decision (for example, whether to call the other party's user and discuss the problem, or to lower the transmission rate). This feature allows users to ask if they should try sending the message again and prompt them to take action.

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

Figures 1a and b are chart diagrams explaining the control procedure of the G-standard. 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

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

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).

When the image signal is finished being transmitted, 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
C (C mode message end signal), and in response, the receiver side outputs 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 again, 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.

Configure each 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 8, respectively.

c 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. If the signal is, for example, the CED, it is output to the signal line 13a through the BPF 5 and the rectifier circuit 9. Similarly, in the case of GI2, BPF6, 7, rectifier circuit 10,

It passes through the rectifier circuit 12 and the signal line 13d. The signal lines 13a to 13d input respective signals to the control circuit 17. The control circuit 17 determines the frequency of the input signals and the order in which they arrive, and outputs signals for display to the signal lines 14a to 14P.
Light emitting elements (for example, light emitting diodes) 15a to 15P are connected to the signal lines 14a to 14P, respectively, and the light emitting elements 15a to 15P are connected to the display board 16a.
-16P respectively. Display board 16
Even if a to 16P are transparent or semitransparent (for example, diffusive) and transmit or diffuse the light of the light emitting elements 15a to 15P, they may be opaque and provided near the light emitting elements 15a to 15P. It's okay to have something like that.

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 inputs the "CED" signal from the signal line 13a, a current flows through the signal line 14a to light the light emitting element 15a, and the display board 1
6a is brightened for 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, the control circuit 17
When the input of the signal is completed, a signal is output from the signal line 18, the switch 2 is switched to the contact b side, and the signal ``GC2'' (or ``GCC'') is sent from the signal line 19, and at the same time, the signal line 14g or A current is applied to 14h to light up the light emitting element 15g or 15h and brighten the display board 16g or 16h for 1.5 seconds or 1.4 seconds. The amplifier 4 amplifies the "GC2" (or |GCC) signal input from the signal line 19 and sends it out to the line 1 via the switch 2.
In the case of the G mode, the PHASE (phase signal) is successively transmitted, and at the same time, the light emitting element 15g is turned off and the light emitting element 15i is turned on. After sending out the phase signal, switch 2 is switched from contact b side to contact a side, and from line 1 the above “CFR2” (or |CFR C)
Input the signal. In this way, the control circuit 17 switches the switch 2 when inputting a signal from the telephone line 1.
is switched to the contact a side, and when sending a signal to the telephone line 1, the switch 2 is switched to the contact b side. In the display boards 16a to 16P shown in FIG. 2, the ○ marks (for example, CED, GI2, etc.) are display boards that become bright when the own aircraft is receiving a signal, that is, when switch 2 is on the contact a side. , 〓〓mark (for example
GC2, GCC, etc.) is a display board that becomes bright when the own machine is transmitting a signal, that is, when switch 2 is on the contact b side, and the mark is a display board that shows the status of the device. The subsequent control procedures are also shown in Figure 1 a and b.
Since the procedure described above is followed, the operations after "CFR2" (or "CFR C") can be explained in the same way. Then, the "END" display lights up in response to the PIS signal.

Although FIG. 2 shows the configuration of the transmitter, the receiver can also be implemented by changing the bandpass filter and display board.

Figure 3a shows the display boards 16a to 16 shown in Figure 2.
FIG. 3b shows a plan view of the display section of the transmitter showing the arrangement of P, and FIG. 3b shows a plan view of the display section of the receiver. When signal transmission starts, the display board 16n in Figure 3a becomes brighter on the transmitter side, indicating the "transmission" status, and on the receiver side, the display board 16n showing "receiving" in Figure 3e becomes brighter. . Since Figure 3b corresponds to Figure 3a, the explanation will be omitted below.
Figure a will be explained. In Figure 3a, G

Each display board becomes brighter in the order of m and 16o. For example, if the display board 16P (ERR) becomes bright while the display board 16h (GCC) becomes bright, it is known that an error has occurred in the high speed mode (GC2). You can make decisions such as switching to mode (GCC).

Note that the 〇 and 〓〓 marks on each display board shown in Figure 3b are reversed compared to each display board shown in Figure 3a, but the operating order of each mode is the same as in Figure 3. Same as a.

As described above, since the facsimile device of the present invention can read the operating state of the device from the display section, it is possible to eliminate operational anxiety and concerns about erroneous operation, and even in the case of an error, an appropriate judgment can be made.
