Abstract

PURPOSE:To attain the communication by manual dialing to a composite terminal equipment Whose incoming call mode is controlled by a facsimile call signal by providing a means setting the presence of transmission of the facsimile call signal at the manual dialing on the facsimile equipment. CONSTITUTION:The transmission of a facsimile call signal is set by the operation of a key 7a of an operation input section 7 in the facsimile equipment in which an opposite station is dialed by manual dialing to make facsimile communication. Thus, the mode setting to send the facsimile call signal is displayed on a display section 8 or recorded and outputted by a storage section 3 and then the facsimile call signal is sent. Since the facsimile call signal is sent even in the manual dialing procedure in this way, facsimile communication is surely implemented without need for troublesome mode changeover even to a composite terminal equipment being a facsimile equipment and a telephone set in which the facsimile call signal is used for the mode changeover.

[Problem to be Solved by the Invention] On the other hand, in recent years, in order to make effective use of telephone lines, facsimile receivers (especially facsimile + telephone, facsimile + answering machine, etc. (voice/non-voice composite terminals) are increasing.

[0005] One of the automatic telephone/facsimile switching systems for these composite terminals is to detect a calling signal from the network and automatically seize the line, and then proceed to the facsimile reception procedure only when a CNG signal is detected. However, if this is not the case, the operator of the receiving station is called or an answering machine is activated, assuming that a telephone conversation is requested.

However, the CCITT recommendation T. 3

NG) Since it does not send out signals and communication is performed entirely manually, the drawback is that it is impossible to send facsimile messages to receivers that use the above method. there were. If automatic transmission mode is used, a CNG signal is transmitted, allowing facsimile transmission. However, for users who mainly use manual mode, it is troublesome to switch modes each time, and users are not required to know how to deal with such problems. If this is not known, it may be determined that there is a malfunction.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a facsimile apparatus which can communicate in a manual call mode even with a complex terminal whose call reception mode is controlled by a facsimile call signal.

[0008]

[Means for Solving the Problems] In order to solve the above problems, in the present invention, in a facsimile device that calls a partner station by manual call operation and performs facsimile communication, a facsimile call can be performed when making a manual call. We adopted a configuration that includes means for setting whether or not to transmit a signal.

[0009]

[Operation] According to the above configuration, the setting means allows facsimile calling signals to be transmitted even in a manual calling procedure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below based on embodiments shown in the drawings.

FIG. 1 is a basic block diagram of a facsimile machine employing the present invention. In the figure, reference numeral 1 denotes a main control section that controls the operation of the entire apparatus, and is composed of a microprocessor, a ROM storing programs to be described later, a work area RAM, and the like. The reference numeral 2 is a reading section composed of a CCD image sensor, a document conveyance mechanism, etc., and the reference numeral 3 is a recording section composed of a thermal printer, a laser beam printer, etc.

Reference numeral 4 denotes a modem that modulates and demodulates procedure signals and image signals in accordance with CCITT recommendations, and an NCU.
This is a communication control unit consisting of, etc. Reference numeral 5 is a telephone for manual line control or telephone calls.

Reference numeral 6 is a communication line (telephone line), reference numeral 7 is an operation input section consisting of a keyboard including a start key, stop key, various function keys, etc., and reference numeral 8 is a display section consisting of an LCD and the like.

Next, the operation of the above configuration will be explained. In the present embodiment, unlike the conventional case, it is possible to set a CNG signal to be transmitted even when making a manual call. for example,
It is assumed that a key 7a is provided in the operation input section 7, and a mode setting for whether or not to transmit a CNG signal is performed depending on the operating state of the key 7a.

This mode setting state can be displayed on the display section 8 or recorded on the recording section 3 at any time or as needed. For example, L of display section 8
When displaying the constant mode by turning on and off the ED, the CNG signal is sent when the ED is on, and the CNG signal is not sent when the ED is off, and the lighting and turning off (that is, mode setting) is switched each time the above-mentioned key is pressed.

FIG. 2 is a schematic flowchart of the manually operated transmission side of the apparatus of FIG. In the figure, step S
Steps 1 to S6 are controls related to operator operations, and steps S7 to S12 are related to internal control of the facsimile machine. The procedures of steps S7 to S12 are controlled by the main control section 1.

First, the operator hears a dial tone in step S1, and dials a required number in step S2. Next, in steps S3 and S4, the process waits for a predetermined period of time until a ring tone is heard.

If the ring tone is not heard within the predetermined time, the process proceeds to step S6, where the call is hung up and the transmission is abandoned. On the other hand, if the ring tone is heard within the predetermined time, the process proceeds to step S5, and the start key provided on the operation input section 7 is pressed to connect the facsimile device to the communication line.

After the line is connected, the facsimile machine executes a loop of steps S7 to S10 for a predetermined time (initial identification time T1=35+5 seconds defined in the T.30 recommendation).

In step S7, if a significant facsimile procedure signal (CED (Called Station Identification) or DIS (Digital Identification) signal) is detected, the other station is in facsimile mode and CNG signal transmission is not necessary. The process exits the loop and proceeds to step S12, where the process proceeds to a facsimile transmission procedure.

If no significant signal is detected even after a predetermined period of time has elapsed, the loop is exited and the process returns to step S11.
Go to and open the line.

Furthermore, while the loop of steps S7 to S10 is being executed, it is determined in step S9 whether or not the CNG signal transmission mode has been set, and if the mode for transmitting a CNG signal has been set, step S1 is executed.
0, the CNG signal is sent out. The CNG signal transmission mode can be determined by determining a flag set in the RAM of the main control section 1 based on the operation state of the key 7a of the operation input section 7.

[0023] In this way, by making it possible to transmit a CNG signal even during a manual call procedure, when a call is received, the CN
Composite terminals that perform automatic telephone/facsimile switching, which are set to switch to facsimile reception procedure only when a G signal is detected, can be switched to facsimile mode using a CNG signal, eliminating the need for troublesome mode switching. This has the excellent effect of allowing facsimile communication (sending, polling reception, etc.) to be performed without having to do so.

In the above embodiment, a CNG sending key is provided in the operation input section 7 as a means for selecting whether to send or not send a CNG signal, but the RAM setting value (
A method of making the selection by rewriting the memory switch (memory switch) may also be considered.

[0025]

As is clear from the above, according to the present invention, in a facsimile device that calls a partner station and performs facsimile communication by manual calling operation, whether or not a facsimile ringing signal is transmitted during manual calling. Since the configuration is equipped with a means for setting, the above setting means allows facsimile ringing signals to be transmitted even during manual calling procedures, and for complex facsimile/telephone systems where facsimile ringing signals are used for mode switching. This also has the excellent effect of ensuring reliable facsimile communication without requiring troublesome mode switching on the terminal.
