Abstract

PURPOSE:To prevent useless dialing by counting number of times of failed line connection consecutively, comparing it with a preset allowable value, detecting the presence of a fault of the line control section and the line to stop the automatic dialing. CONSTITUTION:The line control section 1 uses a count section 3 to count number of times of dialing, compares the count of the counter 3 with the value of the comparison memory section storing the allowable dialing failure number and a discrimination section discriminates the propriety of the succeeding dialing. Then a dial control section 2 applies dial control based on the output of the result discriminated by the discrimination section 5. Then the operator can recognize the production of communication fault and stop the automatic dialing. Thus, useless dialing due to communication fault is not repeated.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a facsimile machine, and is directed to a facsimile machine which is equipped with a function of automatically transmitting original documents, and which eliminates unnecessary repetition of calls due to a failure in one call. The present invention relates to a facsimile machine that has been improved so as to prevent this from occurring.

(Prior Art) Conventionally, the part of this facsimile machine that makes calls is composed of a line control section 21 and a call control section 22, as shown in FIG. Connected.

When making a call, the first call control section 22 sends the telephone number of the other party to whom connection is desired to the line control section 21. Therefore, the line control section 21 sends the telephone number received from the call control section 22 to the line 10.

(Problems to be Solved by the Invention) Does the above-mentioned conventional facsimile machine automatically make calls regardless of the presence or absence of communication failure? Because I repeat.

Even if a call to one destination fails, the second destination automatically makes a call to another destination.

Therefore, when a single call fails due to a line failure or line control unit failure.

Later, the call to another destination also fails, and the operator has no chance of knowing that a communication failure has occurred, so the call operation is repeated repeatedly. There is a drawback.

The object of the present invention is to eliminate such drawbacks.

An object of the present invention is to provide a facsimile device which is improved so as to avoid repeating unnecessary calls due to communication failures, etc.

(Means for Solving the Problems) In order to achieve the above object, the facsimile apparatus of the present invention includes a line control section 1, a counting section 3 for counting the number of times the line control section l has failed to make a call, and a facsimile machine according to the present invention. A comparison memory section 4 stores a permissible number of failed calls, and a determination section 5 reads and compares the value t of the count section 3 and the comparison memory section 4 to determine whether or not to make the next call. The configuration includes a call control section 2 that performs call control based on the output of the judgment result of the judgment section 5.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

As shown in FIG. 1, this embodiment has one line control section, 1% call control section 2. Count section 3. Comparison memory section 4% judgment section 5
It is made up of.

The line control unit 1 is used by being connected to the line IO.

The call control section 2 is connected to the 1 line control section 1 and the determination section 5, outputs a 1 determination request signal 11t to the determination section 5, and inputs a 1 determination result signal 12.

Here, if the logic of the 1 determination result signal 12 is "true", the call control section 2 sends the telephone number of the other party to be connected to the line control section 1. The call control unit 2 receives the 1 judgment result signal 12.
If the logic is "false", the automatic call is terminated and the operator is notified to that effect.

The line control unit 1 receives the telephone number from the call control unit 2 and then transmits the telephone number to the line 10.

In addition, after calling the telephone number of the counting section 1, the line control section 1
When a call is successfully made, a reset signal 13 is sent out, and when one call is unsuccessful, an increment signal 14 is sent out.

The counting unit 3 is connected to the line control unit 1 and the determining unit 5, and when it receives the reset signal 13, it returns the held count value to zero and clears it, and when it receives the increment signal 14, it returns the held count value to 9. Add 1 to . The tit counter unit 3 returns the count value to zero and clears it by a master reset signal 15 that is input from the outside only when the device is powered on. Then, the count section 3 receives the count readout signal 16.
is received from the determination section 5, and the count value held at that time is sent to the determination section 5 as a count value signal 17.

The comparison memory section 4 is! ! Connect part 5 to I4J constant part 5.

A tolerance value is written in advance that is considered to be acceptable even if consecutive call failures occur. Then, it receives a readout signal 18 from the determination section 5 and sends the permissible value to the determination section 5 as an acceptance signal 19.

When the determination unit 5 receives the determination request signal 11-.

outputting a count read signal 16t- to the counting section 3;
A count value signal 17 is received. Furthermore, the determination unit 5 outputs a readout signal 18 to the comparison memory unit 4, and outputs an allowable value signal 19.
receive.

The determination unit 5 compares the count value signal 17 received in this way with the tolerance value signal 19', and if the value of the count value signal 17 is smaller than or equal to the value of the tolerance value signal 19, 1 is determined.
It is assumed that all logics of the determination result signal 12 sent to the call control unit 2 are "true".

Further, when the value of the count value signal 17 is larger than the allowable value signal 19, the determination unit 5 sets the logic of the determination result signal 12 sent to the call control unit 2 to be “false”.

Therefore, as mentioned above, the logic of the determination result signal 12 is "true".
, or "false", the next scheduled call is connected or the automatic call is canceled.

(Effects of the Invention) As explained above, the present invention counts the total number of consecutive line connection failures, compares it with a preset tolerance value, and detects that there is a failure in the line control unit or the line. However, by canceling the automatic call, invalid calls can be prevented.

One example? By using this method and notifying the operator of the detection results, measures against pupil damage can be taken promptly.
