Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an automatic dial device in a facsimile machine or the like.

2. Description of the Related Art In a facsimile machine, an automatic dial device having the following functions has been put into practical use.

If you register a dial number in advance corresponding to the index number to be entered with the one-touch key or abbreviated number key, the registered dial number will automatically be called in response to the operation of the one-touch key. It When the call connection cannot be established, the calling operation is repeated after a predetermined time.

Also, the latest dialed number that has been called is automatically stored in the redial memory, and when a dial command signal is given by the redial key, the dialed number stored in the redial memory (the number called immediately before) Will be called automatically.

Further, according to the dial number registration means capable of registering the main dial number and the sub dial number corresponding to one index number (input by one-touch key or abbreviated number key) and the registered contents of this registration means, first, Calls to the main dial number, and if the call cannot be connected, the sub dial number is called, and if the call cannot be connected, the above operation is repeated. is there. For example, the number of the facsimile device directly under the communication partner is registered as the main dial number, and the number of a nearby facsimile device that can be used preliminary when this is in use is registered as the sub dial number. Then, by simply keying in the index number of the communication partner, it is possible to automatically communicate with either of the two facsimile machines having the main or sub dial numbers.

Problems to be Solved by the Invention The conventional automatic dial device has the following problems. When the above-mentioned main / sub continuous call type automatic calling means is operating, when the main dial number is called, the number is stored in the redial memory, and when the sub dial number is called, the number is stored in the redial memory. It Therefore, when the facsimile machine having the sub dial number is connected, the sub dial number remains in the redial memory. When the redial key is pressed to communicate with the same party in this state, the subdial number stored in the redial memory is called. It is inconvenient to call the sub-dial number first, although the main dial number must be given priority to the communication partner.

The present invention has been made to solve the above problems,
It is an object of the present invention to provide an automatic dial device in which a number registered as a main / sub continuous call type sub dial number cannot be called by a redial calling means.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is configured to store only the main dial number in the redial memory during operation of the main / sub continuous call type automatic calling means.

Operation Even when a call is connected to the sub dial number by the main / sub continuous call type automatic calling means, it is not the sub dial number but the main dial number that remains in the redial memory. Therefore, if a redial operation is performed immediately after that, the primary dial number, which is the priority number, is always called and the sub dial number is never called.

Embodiment FIG. 2 is a schematic block diagram of an automatic dial device according to an embodiment of the present invention. The hardware configuration is the same as the conventional one, a keyboard 1 including dial keys, one-touch keys and various function keys, a display 2 including a liquid crystal panel, a registered dial memory 3, a redial memory 4, and a dial signal generation circuit. 5, a network control circuit (NCU) 6, a modem 7, and a central processing unit (CPU) 8 for centrally controlling these.

In the registered dial memory 3, one dial number can be registered corresponding to one index number, and two numbers of a main dial number and a sub dial number can be registered corresponding to one index number.

The CPU 8 reads the dial number corresponding to the index number input from the keyboard 1 from the registered dial memory 3 by using the manual calling mode in which the dial signal generation circuit 5 is driven by the dial number input from the keyboard 1 The automatic calling mode for driving the dial signal generating circuit 5 is controlled. In addition, the latest dialed number that made the calling operation is stored in the redial memory 4, the dialed number is read from the redialed memory 4 in response to the redial command signal from the keyboard 1, and the dial signal generation circuit 5 is driven by that number. It also controls the redial calling mode.

The flowchart of FIG. 1 shows the control procedure of the automatic call-out mode. When the index number for automatic calling is input to the one-touch key of the car board 1, the dial number of the corresponding area of the registered dial memory 3 is read. Memory 3
There is a case where only one dial number is registered in the corresponding area, and a case where two main dial numbers and sub dial numbers are registered. Since the former is not directly related to the present invention (but is well known), the operation in the latter case will be described.

First, the dial signal generating circuit 5 is driven according to the main dial number to make a call (step 101), and then it is checked whether or not the number just called is the number registered as the sub dial number (step 102). . In the above description, since it is not the sub dial number, the called number (main dial number) is written in the redial memory 4 (step
103).

Next, it is determined whether or not the other party is busy (step 104), and if not busy, the line is connected (step 106), but if busy, it is checked whether or not the automatic call is repeated 6 times. (Step 105).

Since automatic calling has not been repeated in the above description, the process returns to step 101, and the sub-dial number is called next. At this time, step 102 becomes YES and step 103
Since the sub-dial number is skipped, the sub-dial number is not written in the redial memory 4 and the main dial number remains in the memory 4. If the sub-dial number is busy, step again.
Returning to 101, the main dial number is called. In this way, when the main dial number and the sub dial number are alternately called and the call connection cannot be established even after performing this operation 6 times, the calling operation is terminated (step 105).

As described above in detail, in the automatic dialing device according to the present invention, even if the sub-dial number is called by the operation of the main / sub-continuous call type calling means, the number is written in the redial memory. Instead, only the main dial number is written to the redial memory. Therefore, the sub-dial number is not called by the redial call operation, and the inconvenience of unintentionally calling the auxiliary sub-dial number can be eliminated.
