Abstract

PROBLEM TO BE SOLVED: To prevent a recall out from being made at the time of mis-dialing on a telephone set by preventing a redialing, when a push tone signal is detected after having made automatic dial to the other party to communicate from a communication terminal which is equipped with an automatic dial function, a circuit signal detection function and a redial function. SOLUTION: A dial number is inputted with a single-action key or ten keys of a key operating part 8. A counter for redialing is set to zero, a network controlling part 2 having an automatic dial function converts an inputted dial number into a dial pulse or a push tone and sends it to a closed telephone line. A CNG signal is sent to a callee, next, it is discriminated whether or not a DIS signal has been detected. When it has been detected, a facsimile procedure is subsequently carried out and image transmission is executed. When the DIS signal has not been detected, it is discriminated whether or not '*'of a push tone signal has been detected twice. When it has been detected, a line is disconnected.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings showing the embodiments. FIG. 1 is a block diagram showing an example of a configuration of an embodiment when a communication terminal device according to the present invention is embodied as a facsimile device.

In FIG. 1, reference numeral 3 denotes a main control unit of the facsimile apparatus, which includes a CPU (Central Processing Unit), and a ROM (Read Only Memory) storing a program for controlling the operation of the entire facsimile apparatus. 6 and a RAM (Randam Access Memory) 5 as a storage unit for temporarily storing data and temporary data required for control by the CPU.

The main controller 3 is connected to a network controller 2 with an automatic dial function and a modem 4. The network control unit 2 with an automatic dial function is controlled by the main control unit 3 and has a function of connecting the general public telephone line 1 to the facsimile apparatus and converting a telephone number into a dial pulse or a push tone and transmitting it.

The modem 4 has a function of modulating and demodulating transmitted / received data and a function of detecting a push tone signal from a partner telephone or the like and a busy tone from an exchange, which are input from the line through the network controller 2 with an automatic dial function. .

The main control unit 3 is further connected to a voice recognition unit 12. The voice recognition unit 12 compares a voice signal from a telephone or the like input from the telephone line 1 through the network control unit 2 with an automatic dial function with a plurality of voice patterns stored in the ROM 6 in advance and outputs a match detection.

The main control unit 3 is also connected to a display unit 7, a key operation unit 8, a document reading unit 9, a recording unit 10, and a timer 11. The display unit 7 displays a dial number input from the key operation unit, a facsimile operation guide, and details of a failure state such as when the operation of the apparatus is not completed normally. The key operation unit 8 includes, for example, numeric keys and one-touch keys for inputting a telephone number, and start and stop keys (not shown) for instructing operation of the apparatus.

The original reading section 9 reads an original image to be transmitted by facsimile using, for example, a CCD image sensor or the like. The recording unit 10 records the received image and prints and records the contents of the failure state such as when the operation of the apparatus is not completed normally. The timer 11 is an interval timer for outputting a signal to the main control unit every one second.

The voice recognition unit 12 receives an input from a telephone line,
The voice data converted from analog to digital by the modem and stored in the RAM 5 is compared with the voice pattern data previously stored in the ROM 6 to detect a match.

Next, the operation of the facsimile apparatus having the above-described configuration will be described with reference to the flowchart of FIG.

First, a dial number is input by a one-touch key or a numeric keypad of the key operation unit 8 (step 10).
0). The counter for redialing is reset to 0 (S102). The input dial number is converted into a dial pulse or a push tone by the network control unit 2 with an automatic dial function, and transmitted to a closed telephone line (S1).
04). Next, the signal detection wait timer is set to 60 seconds, and the timer is started (S106). In order to indicate to the called side that the transmitting side is a communication terminal device, a CNG signal (11
(ON for 0.5 second with 00Hz tonal signal) (S
108). Next, it is determined whether or not a DIS signal indicating the receiving capability of the called facsimile apparatus has been detected (S110). If the DIS signal has been detected, the facsimile procedure is executed thereafter to transmit an image (S124).

If no DIS signal is detected, S112
It is determined whether or not "*" of the push tone signal is detected twice. If it is detected, the line is disconnected (S128), and "Denwabango Gachigaimasu" is displayed on the display unit 7 (S1).
30) Then, the recording unit 10 prints and records "ITEGAX FAX DEHA ALIMASEN" (S132). In addition, line disconnection (S1
28) Before the speech, the voice of "I made a mistake in the telephone number. I'm sorry."

If no push tone signal is detected in S112, the voice recognition unit 12 performs voice detection (S114). The voice pattern is stored in the ROM 6 in advance,
As speech, it remembers the words used as the first voice of telephones in each country, such as "Hello", "Hello", and "Pronto". If any sound is detected as a change in the amplitude of the signal, a plurality of sound patterns in the ROM 6 are compared with the sound received and stored in the RAM 5 (S126). When any one of the voice patterns matches, the line is disconnected (S1).
28) Thereafter, when a push tone is detected (S114 YES)
In the same manner as described above, an error message is displayed (S130), an error message is printed (S132), and the process ends.

If no voice signal is detected or the voice does not match the pattern, the time-up of the 60-second timer is detected (S116). If 60 seconds have not yet passed, S1
Returning to step 08, a CNG tone signal is transmitted. On the other hand, if 60 seconds have elapsed, the line is released (line disconnected) and 1 is added to the redial count (S118). As a result, if the re-dial count reaches 10, the process ends without redialing thereafter. If the re-dial count is less than 10, wait three minutes (S122) and then dial the same party again (S104). When the redialing is completed ten times and the processing is completed, a message such as "Could not be connected to the other party" may be displayed on the display unit 7 or the recording unit 10. Although the push tone signal is "**", it is needless to say that other tones "#" and "0-9" may be used. The number was set to two, but this is for confirmation because of the possibility of being mistaken for voice, and may be one. Further, the example in which the voice pattern is stored in the ROM 6 in advance has been described. However, the voice pattern may be registered in the RAM 5 by inputting characters from the key operation unit 8 using character keys (not shown). As described above, if a push tone signal or voice is detected from the called
Since the NG signal is stopped and the other party is not redialed, the called party is not bothered.

[0018]

According to the first aspect of the present invention, the communication terminal apparatus automatically dials a predetermined destination for communication, and does not redial when a push tone signal is detected from the called side. It does not uselessly call the previous telephone and does not use the line wastefully. Also, it does not bother the other party. The communication terminal device according to the second aspect of the present invention automatically dials a predetermined destination in order to perform communication and, when detecting voice from the called side, can confirm that the other side is a person. There is no needless call to the telephone and no use of line is wasted. Also, it does not bother the other party. The communication terminal device according to the third aspect of the present invention automatically dials a predetermined destination to perform communication and, when detecting a voice or a push tone from the called side, displays on the calling side device that the other side is not a communication terminal. Alternatively, it is printed, so that it is possible to indicate to the operator on the calling side that the telephone number is incorrect.
