Description

The present invention relates to a destination selection device that stores a plurality of destinations.

[Prior Art] Some conventional facsimile machines have one touch dial, and only one telephone number can be registered in this one touch dial.

In this conventional device, when the other party is busy when the automatic dialing is performed, the dialing is performed again (redial) after about 2 minutes. However, in the G3 model, if the communication of 10 pages or more is performed, the number of turns becomes two. After dialing, there is often the problem that there are many people who are busy.

[Object of the Invention] The present invention provides a destination selection device capable of quickly transmitting to a destination associated with the destination when the dialed destination is busy, and thus can quickly send the transmission content to the other person. It is intended to be provided.

Embodiment of the Invention FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, a crystal oscillator 1 generates a reference clock for the entire apparatus, and this clock is given as a reference clock to a CPU (central processing unit) 2 composed of a desired microprocessor or the like. CPU2 uses ROM3, RAM4, timer 5, PPI by data bus and address bus.
(Pro-Pluggable Parallel I / O) 6, 7, 10, UPI (Peripheral
CPU) 9, 11 and 12 are connected. The CPU 2 controls the entire facsimile device and also encodes and decodes image data.

Further, the CPU 2 is an example of dial control means for dialing one of the registered destinations and dialing the remaining destinations among the registered destinations when the other party is busy. Then, the CPU 2 has a function of automatic dialing in the order of the destinations having the smallest number of busy times.

The DMA controller 13 controls memory such as ROM3 and RAM4. The UPI 9 controls driving of originals and recording paper, the UPI 11 controls the parallel-serial converter 25 and the thermal head recording system, and the UPI 12 controls the key input switch 31 and the liquid crystal display LCD 32. It is to display.

The RAM 4 is one of registration means for registering a plurality of destinations for one 1-touch dial button. Further, the RAM 4 stores the number of busy times when automatic dialing is performed.

The modem 14 performs the modulation and demodulation of image data and the transmission / reception of procedure signals for facsimile communication procedures. The network control unit (NCU) 15 connects the line to the telephone 34 side or the modem 14
The connection is switched to the side.

The dialer 16 sends a dial signal to the line according to the telephone number data of the communication device output from the CPU 2 via the PPI 7. In addition to this, the relay 8, the speaker drive circuit 18, the speaker 19, and the analog-digital converter
21 and 21 are provided.

 Next, the operation of the above embodiment will be described.

FIG. 2 is a flow chart showing the operation of the above embodiment.

First, when the transmitting side presses the 1 touch dial button,
One of the telephone numbers registered for the touch dial button is displayed on the LCD 32 (S1). Then, the main power supply is turned on (S2), the polarity inversion is detected (S3),
If the polarity is not reversed (S4) and it is not FC or CI (S5), the sending fax machine is neither busy nor ringing, so control the NCU15 to connect the fax machine to the line. Wait for 3.2 seconds (S6), then display "Dial Chu" on the display (S7).

Then, the telephone number corresponding to the one-touch dial pressed as described above, which is registered in the dial memory, is dialed. That is, the CPU 2 controls the dialer 16, switches the switch provided between the NCU 15 and the modem 14, and sends a dial signal to the line via the dialer 16, the switch, and the NCU 15.

Since the polarity is not reversed unless it is connected to the facsimile machine of the other party (S9), after 45 seconds have passed (S10), the busy count n is incremented by 1 (S11), and the automatic call count m is also incremented by 1 (S12). , The busy flag F is set to 1 (S13), and the call is made again (S14).

The busy number n and the automatic call number m are both 0 at the initialization stage.

On the other hand, when dialing the other party's telephone number (S8),
If connected to the other party, the polarity is reversed (S9), so the number of automatic calls is reset to 0 (S15) and the busy flag F is also set to 0.
Reset to (S16) and return (S17).

FIG. 3 is a flow chart showing the dialing (S8) of the telephone number in FIG. 2 in more detail.

When dialing the telephone number in S8, it is determined whether the busy flag F is 1 or 0 (S21). That is, as a result of the previous dialing in the automatic call, the flag F is 1 when the other party is busy, and the flag F is 0 when the other party is not busy. In the above case, the busy flag F is 0 because the automatic call has just been made for the first time. Therefore, the telephone numbers in the dial memory are rearranged in ascending order of the number n of busy times in the past (S25).

That is, the contents of the dial memory shown in FIG. 4 (1) are rearranged into the contents of the dial memory shown in FIG. 4 (2). This number comes to the highest priority, as the number 723 ₀₀₀₀ has the lowest busy count of 18, which is the lowest.
Then, the last-ranked telephone number (723 ₀₀₀₀ ) is dialed (S26), and the process returns.

On the other hand, in S21, if the previous party is busy, the flag F is 1, and the automatic call number m is set to 1,
Since the number of registered lines is four as shown in FIG. 4, the highest priority (that is, 1) + mth (that is, second) telephone number (723 XXXX) is dialed (S23). in this case,
Since the busy count n is incremented by 1 in S11, the cumulative busy count of the telephone number 723 ₀₀₀₀ becomes 19. This state is shown in FIG. 4 (3).

In this way, the other party is connected and predetermined data is transmitted.

On the other hand, in the above case, if the connection is not made yet, the number of automatic calls m becomes 2, and next time, the telephone number 723 △ △ △ △
Is dialed.

In the process of performing the above operation, the possibility of connecting with the other party increases.

In FIG. 3, if the number of registered lines for one one-touch dial button is 1, the busy flag F is reset to 0 (S24), and the one registered line is repeatedly redialed.

At present, the number of facsimile machines installed in one company or one floor is two to three, or more than two companies are installed in one section. Therefore, if these facsimile devices are registered in one one-touch dial button and dialed sequentially, the probability that the other party is busy when a call is made and then the communication is possible when the redial is made is increased.

In the above embodiment, the number of registered rotations is 4, but it may be a number other than 4.

EFFECTS OF THE INVENTION According to the present invention, when the dialed destination is busy, the destination can be quickly transmitted to the destination associated with the destination, and thus the transmission content can be quickly transmitted to the other person. Play.
