Abstract

PURPOSE:To surely perform the monitor of a line and polling reception by providing a means to switch a transmission mode and a line monitoring mode based on the presence/absence of an original before or after transmission, and a means to perform the polling reception by a key input instruction under monitoring the line. CONSTITUTION:By inputting a dial number from an operation panel 4, the dial number data is transferred to a CPU 1. Next, the dial number data is sent to the line by controlling a selection signal sending circuit 8 by a PIO 9. And after sending a selection signal, an original sensor 11 is sensed via a PIO 13. When no original exists, the monitoring is started so that a line state can be heard by an operator. Next, it is decided whether or not a FAXF flag is set by detecting the inversion of polarity, and when the FAXF flag is set, an operation is shifted to the polling reception.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile machine having a function of switching modes depending on the presence or absence of a document.

[Conventional example] Conventionally, this type of device has given priority to the facsimile function, so it operates in transmission mode and polling reception mode depending on the presence or absence of a document during auto dialing, and if there is 0FFHooK in the TI timer, It was designed so that it could be switched to the receiver side and used as a telephone. For this reason,
CN can only monitor the T1 timer time of the facsimile procedure and is an auto dialer.
G was sent out, giving an unpleasant impression to the other party (when it was a human).

In order to solve the above problem, a specification was devised in which the facsimile transmission mode is used when there is a document, and the telephone mode is used when there is no original.

However, with this specification, when used in stationary mode, although it was easy to use, there was an inconvenience that only polling reception could be performed. actual,
Although it is not impossible, since the start button is pressed after 0FFHooK to start, the reception operation is performed at first, and the DIS collides with the other party's device, making it impossible to perform reliable polling reception.

[Objective] The object of the present invention is to eliminate the drawbacks of the above-mentioned conventional example, and to solve the problem in telephone monitor mode.

To make it possible to listen to telephone services such as weather forecasts for a long time in the 0NHooK state, and at the same time to ensure polling reception in the case of a facsimile from the other party.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of this embodiment,
FIGS. 2(a) and 2(b) are flowcharts showing the control operation of this embodiment.

In FIG. 1, 1 is a main CoU that controls the system. 2 is a buffer memory for image data, decoding, and encoding, and a one-touch dial number storage memory. 3 is a drive system. 4 is an operation panel having multiple key input switches such as a numeric keypad for auto dialing, a one-touch key, and a start key; the operation panel performs key sensing;
If there is an input, the input key data is passed to CPU 1.

5 is a recording system, and 6 is a reading system. 7 is the modem,
8 is a dial pulse or DTMF ()--n dial signal) sending circuit. 9 is an input/output interface PIO, which connects the selection signal sending circuit 8 and NCUlo to the CPU.
Controlled by access from I. lO is NC
At U, signals from the selection signal sending circuit 8 and modem 7 are sent to the line, or signals from the line are input to the modem side.

Next, in the above configuration, FIG. 2(a) shows.

This will be explained according to the flowchart in (b).

First, in step S1, when a dial number is input from the operation panel 4, the dial number data is passed to the CPUI. (This or the main CPU if you use one-touch dial input.)
I" accesses the dial number corresponding to the touch from memory 2.) Next, in step S2, the dial number data is PIO
9 controls the selection signal sending circuit 8 and sends it to the line. After sending the selection signal in step S3, the PIO
The original sensor 11 is sensed through the sensor 13.

Here, if there is a manuscript, it passes through bus A and step S17
~ In S19, the normal transmission operation is performed. If there is no document, monitoring of the line status is started in step S4 so that the operator can check the line status.

Then, in step S5, the facsimile hauling error (FAXF flag) is cleared.

Next, in step S6, timer T2 is set to 45 seconds,
Step S7. S8. In S9, it monitors whether the polarity is reversed or not and the start key is monitored for 45 seconds, and if the polarity is not reversed for 45 seconds and the start key is not pressed, the line is released and the line returns to the standby state. Also, if the polarity reversal is detected within 45 seconds, the process advances from step S8 to step Sll, and if the start key is pressed, the process advances from step S9 to step SIO, where the FAXF flag is set to 1 and a polling reception instruction is memorized. I'll keep it.

Next, when detecting polarity reversal and proceeding to step Sll, F
Determine whether or not the AXF flag is set, and
If the XF flag is set, the process moves to polling reception, and if the FAXF flag is not set, the process moves to step S12. Proceeding to step S12, the timer T2 is newly set for 8 minutes, and the line monitor is turned on. And step S13. S14゜In S15, it is sensed whether the off-hook and start keys have been pressed during the 8-minute monitor, and if it is off-hook, it is a response to the operator, so in step S16 the line is switched to the telephone side, the state goes to standby, and the start key is pressed. If it is on, it shifts to polling reception mode.

As explained above, key sensing is performed even during line monitoring after a call is made without a document, and if the start key is turned on, polling reception is performed, thereby achieving the following effects.

When used as a telephone (make a call without inserting a document), you can continue monitoring for a long time in an on-hook state. (When asking for weather forecasts, etc.) Kabu, when responding to the other party personally, since the call is not made in facsimile mode, a CNG (calling tone) is sent out to avoid making the other party feel uncomfortable and to ensure reliable Bau link reception. I can do it.

[Effects] As described above, according to the present invention, it is possible to monitor the line for a long time even in the automatic communication mode, and it is possible to reliably receive the baud link.
