Abstract

PURPOSE:To allow the automatic dialer to surely cope with even the service such as an F-PORT by providing a destination information storage means, a destination information read means, a specific instruction detection means and a secondary dial tone detection means or the like and sending a command to read a succeeding destination number to the destination information read means when the secondary dial tone detection means detects a secondary dial tone. CONSTITUTION:When a special instruction detection means 22 judge a destination number read by a destination information read means 21 to be a special instruction, the read of the destination number is once stopped and whether or not a secondary call tone is sent from a line is detected. When the transmission of the secondary call tone is detected, a secondary call tone detection means 23 sends a signal to read a succeeding number to the destination information read means 21. As a result, even when a pause of an optional length comes on the way of the dial, the dialing is normally implemented. Thus, even when the service like an F-PORT is utilized, the dialer is surely operated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic facsimile dialing device, and more particularly to an automatic facsimile dialing device that can cope with pauses of any length between dials.

(Prior Art) Currently available facsimile machines with one-touch dialing or speed dialing functions manually record the telephone number of the recipient in advance in correspondence with the one-touch dialing or speed dialing number, and when sending It has a function that allows you to automatically dial the destination by simply pressing the dial or speed dial number.

By using this function, you do not have to enter each recipient's phone number one by one when sending a message, which saves time and prevents you from entering phone numbers incorrectly.

However, like the F-PORTOR system provided by KDD, which is used when sending facsimiles to foreign countries, the sender's facsimile device must first be dialed to connect to F-PORT, and the connection is confirmed by the secondary dial tone. If there is a need to confirm that the call is correct and then dial the telephone number of the other party, the operator must go through a procedure each time a transmission is made, which poses a problem in terms of operability.

Here, to explain a little about F-PORTOR provided by KDD, as shown in Figure 7, if you try to send document information from facsimile machine A in Japan to facsimile machine B in a foreign country, for example in the United States. , the operator of facsimile machine A first dials the number "005g" to connect to F-PORT.By this dialing, for example, the operator of facsimile machine A dials the number "005g" to connect to F-PORT.
ORT is called.

When the F-PORT is in a connectable state, it sends out a secondary dial tone, so the operator of facsimile machine A dials the telephone number of the other party after confirming the secondary dial tone. Then, the original is read from facsimile machine A and sent to the line.

Then, the F-PORT temporarily stores the telephone number of the other party and the document information, and automatically transmits the information to the facsimile machine 1B, which is the other party, at an appropriate time. If you are unable to send the message due to the other party being busy, etc., the F-P
ORT performs the transmission procedure again and transmits.

As described above, the F-PORTOR functions as a pseudo facsimile device.

Later, in order to solve the inconvenience of sending a facsimile to a foreign country via F-PORT, a facsimile machine that could input a pause was developed. This device has a connection between the F-PORT connection number and the destination telephone number.
A "pause" is inserted in advance at the time when the secondary dial tone is expected to be transmitted, and the transmission of the destination telephone number is delayed by this time.

(Problem to be Solved by the Invention) However, the time from when the F-PORT connection number is dialed until the secondary dial tone is returned to the facsimile machine varies depending on the line condition, and if this time is long, By the time the secondary dial tone is returned, the destination phone number is sent, and F-PORT recognizes the phone number received after the secondary dial tone is sent as the destination phone number, and the correct destination phone number is sent. There was a problem that the number did not reach F-PORT. Also, with this wrong number, F-POR
If a facsimile machine with this number happened to be located in a foreign country, the document information would be sent to this machine, which could lead to the worst possible situation.

The purpose of the present invention is to eliminate the problems of the conventional device described above,
It is an object of the present invention to provide a facsimile machine having a one-touch dial or abbreviated dial function that operates reliably even when using a service such as F-PORT.

(Means and effects for solving the problem) In order to achieve the above object, the present invention provides a destination information storage means for storing a destination number in which a special command is inserted in the middle of the dial number, and destination information reading means for reading out the destination number digit by digit from the information storage means; special command detection means for identifying whether the read destination number is a dial number or a special command; and dialing. It is characterized in that it is provided with dialing means for dialing when it is a number, and secondary tone detection means for detecting the secondary tone from the line when it is a special command.

In the present invention, when the destination number read by the destination information reading means is determined to be a special command by the special command detection means, the reading of the destination number is temporarily stopped, and a secondary call is made from the line. Detection is made as to whether or not sound is being sent. When it is detected that a secondary dial tone has been sent, the secondary dial tone detection means sends a signal to read the next number to the destination information reading means.

As a result, even if there is a pause of any length during dialing, the dialing operation can be performed normally.

The invention according to claim (2) is characterized in that when a busy tone is detected instead of the secondary dial tone, abnormality processing such as redialing is performed.

(Example) The present invention will be described in detail below with reference to the drawings. FIG. 2 is a system block diagram showing the general configuration of a facsimile machine.

In the figure, 1 is a scanner that reads the original, 2 is an encoding unit (codec) that compresses the read original information using an encoding method with high compression efficiency, 3 is an image storage memory that stores the compressed original information, and 4 5 is a modem that modulates the original information read from the image storage memory 3 and demodulates the received original information; 5 is a modem that automatically dials and sends a message to the other party when there is a transmission instruction using one-touch dialing or speed dialing. This is a line control unit (NCU) that calls stations and performs predetermined communication procedures using a predetermined protocol.

Reference numeral 6 indicates a printer that prints the received document information; 7 indicates an operation panel having a numeric keypad, various function keys, a display section, etc.; and 8 indicates C, which controls the operations of the various blocks described above.
PU 9 is a ROM 10 that stores control programs and various basic data for operating this system.
is a RAM that provides a work area and stores speed dial data and the like registered from the operation panel 7.

The present invention adds a new function to the facsimile apparatus having the above configuration, and this function will be explained with reference to FIG. FIG. 1 shows a functional block diagram of an embodiment of the present invention.

In FIG. 1, the input operation means 7a is the operation panel 7.
The other party information storage means 10a which stores the other party information inputted from this manual operation means 7a is the RAM.
Corresponds to l0. Further, 21 is a destination information reading means;
2 is a special command detection means, 23 is a secondary beep detection means, 2
4 is a dial means. It is assumed that the destination information reading means 21 and the special command detection means 22 correspond to some functions of the CPU 8, and the secondary dial tone detection means 23 and the dialing means 24 correspond to some functions of the line control section 5. be able to.

FIG. 3 shows a conceptual diagram of data stored in the destination information storage means 10a. The destination information storage means 10a stores one-touch or speed dial numbers and destination numbers in correspondence.

For example, the destination number corresponding to one-touch number 01 includes the number ro 058J that calls the F-PORT, the special command rlE9J, and the destination phone number rl.
23456J is stored. This special command e is
This was introduced in this embodiment.

Next, the one-touch dial number 01 of the input operation means 7a
The operation of the circuit shown in FIG. 1 will be explained assuming that the button is pressed.

When the one-touch dial number 01 on the input operation means 7a is pressed and then the transmission instruction operation is performed, the destination information reading means 21 starts operating and the destination information storage means 10
Read the destination number one digit at a time from a. The read destination number is sent to special command detection means 22, and it is determined whether it is a normal number or a special command. Since the number r0058J is determined to be a normal number, these numbers are sent one digit at a time to the dialing means 24 and dialed. Note that the dialing means 24 sends a dialed signal to the destination information reading means 21 every time one digit is dialed. When the destination information reading means 21 receives the dialed signal, it reads the next number from the destination information storage means 10a.

Now, when the special command detecting means 22 detects the special command, the secondary beep detecting means 23 operates, and the F-PO
It detects that a secondary tone, that is, a 2100 Hz signal is sent from the RT.

This signal is a signal to notify that F-PORT has received a call.

When the secondary beep detection means 23 detects this secondary beep, it outputs a next signal, which is a signal instructing to read out the next digit, to the destination information reading means 21.

When the destination information reading means 21 receives this next signal, it reads the next one-digit number of the special command from the destination information storage means 10B.

In this way, the recipient's phone number rl 2345
6J is correctly read out, sent to the F-PORT via the dialing means 24, and stored. Next, the document information is read by a scanner (not shown) and sent to the F-POR.
It is sent to T and stored.

As described above, according to the present embodiment, the secondary dial tone detection means 23 detects the secondary dial tone, and when detected, sends the telephone number of the destination party to the F-PORT.
Even if there are variations in the time (pause) it takes for the line to connect to the F-PORT after automatically dialing the number that calls the F-PORT, this will cause the wrong destination phone number to be sent to the F-PORT. This problem will disappear.

FIG. 4 is a flowchart showing the above operation. Since the meaning of this flowchart is considered to be clear to those skilled in the art, the explanation will be omitted.

Next, a second embodiment of the present invention will be described with reference to FIG. In the figure, the same or equivalent parts as in FIG. 1 are given the same reference numerals.

This embodiment is designed to cope with the case where all F-PORT lines are blocked and a busy tone is returned when F-PORT is read from a facsimile machine.

31 is a secondary dial tone and busy tone detection means;
When a 100 Hz signal is detected, a next signal is output to the destination information reading means 21. On the other hand, when a busy tone is detected, the timer 32 is activated. When the timer 32 measures a predetermined time, it outputs a reset signal to the destination information reading means 21. As a result, the destination information reading means 21 operates to read out the destination number stored in the destination information storage means 10a again from the beginning. That is, a redial operation is performed.

FIG. 6 is a flowchart showing the processing of this second embodiment. In addition, as an abnormality processing after busy tone detection,
Although a telephone dial is used in this embodiment, the present embodiment is not limited to this. It is also possible to display this on a display device on the console panel, or to record it in a communication management report. You can. Alternatively, it is also possible to simply register that fact in memory.

(Effects of the Invention) As is clear from the above explanation, according to the present invention, even if there is a pause in the middle of automatic dialing, even if there is a change in the length of the pause, this can be reliably accommodated. effective.

Therefore, it has the effect of being able to reliably support services such as KDD's F-PORT.
