Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an image communication device having an automatic calling function and an automatic receiving function.

BACKGROUND OF THE INVENTION Conventional devices of this type have been equipped with an automatic calling function to automatically call the other party.

In addition, some devices were equipped with an automatic reception function that automatically transitioned from a call standby state to an image reception state when a call was received from the other party, making it possible to perform so-called missed reception. .

Problems to be Solved by the Invention However, with this configuration, there is a problem that the operating procedure when calling a communication party from the own station side and receiving an image from the called communication party is cumbersome. there were.

The above problem arises for the following reasons.

In other words, conventional image communication devices of this type have an automatic calling function and an automatic receiving function as mutually independent functions. After calling the other party using the calling function, wait in the call mode for the signal tone indicating the start of image transmission to be sent from the called other party, and switch to the image reception mode when the signal tone is heard. Manual configuration steps were required.

In other words, although each call origination and reception operation is automated, the operations from the time the call is made until the start of reception requires a cumbersome manual operation procedure.

Note that there is a polling function as a means to solve the above-mentioned trouble. With this polling function, the calling party automatically receives an image transmission performed by the called party based on a request from the calling party. However, this requires that both the calling and called parties have the same type of polling capability. Moreover, in communication using the polling function,
Another problem is that it cannot be applied to image communications performed using normal communication control procedures because a special communication control procedure involving password exchange and the like is executed.

The present invention has been made in view of the above-mentioned problems, and the present invention allows a communication partner to be called from the own station side without using a special communication control procedure such as polling communication, and the called communication partner can then call the communication partner. An object of the present invention is to provide an image communication device that can simplify operating procedures when receiving images.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a control means including a control function that automatically shifts to an image reception mode after the call operation by the automatic call function is completed; The apparatus includes a setting section for specifying a control function to be executed by the control means, and is configured to cause the control means to execute the control function according to the setting contents of the setting section.

Effects of the present invention With the above-described configuration, the transition from calling to receiving is automatically performed by simply specifying the type of control function to be executed by the control means via the setting section. For example, it is possible to greatly simplify the operating procedure when calling a communication partner from the own station and receiving images from the called communication partner without using special communication control procedures such as polling communication. It becomes possible.

Here, the communication line is a normal public telephone line or a dedicated facsimile line.

The incoming call detection unit 1 detects a 16 Hz paging signal sent from the exchange based on a dial call from the calling terminal. The detection output is input to the control section 7. This incoming call detection section 1 is provided to perform automatic reception based on incoming calls.

The NCU 2 performs line connection (hook-off) and disconnection (hook-on) under the control of the control unit 7 .

The automatic calling device 3 performs automatic calling operations such as dialing based on commands and data from the control unit 7, and monitors the polarity of the telephone line to determine whether the calling operation is complete. The control unit 7 detects whether or not the terminal of the communication partner is connected via the switching center.
Notify.

The telephone 4 is a regular telephone equipped with a handset.

The facsimile device section 5 includes a facsimile receiving function, a facsimile transmitting function, and the like.

The facsimile reception function includes a modem 51 that demodulates a coded image signal from a received signal, an expansion unit 52 that decodes the demodulated coded image signal, and a recording unit 53 that prints and records the decoded image signal on recording paper. Consisted of. Reference numeral 54 indicates a received document printed and recorded on recording paper.

The facsimile transmission function includes an image reading section 56 that reads the image of the original 55 line by line, a compression section 57 that encodes the image signal from this reading section 56 to reduce the amount of information, and a compression section 57 that modulates the encoded image signal. It is composed of a modem 51 and the like.

Each function within the facsimile device section 5 operates under the control of the control section 7.

The switching section 6 selects either the telephone 4 or the facsimile device section 5 and connects it to the line in accordance with a command from the control section 7.

The control section 7 centrally controls the operations of the above-mentioned sections, and is configured using a general-purpose information processing device formed into a microcircuit, ie, a so-called microconbeater. In addition to the control function for realizing the function of a normal facsimile machine, this control unit 7 has an automatic calling device that automatically shifts to a facsimile reception mode after the automatic calling device 3 completes the calling operation. Contains call reception control functions.

The operation panel 8 includes an input section 81 for inputting a telephone number, etc.
and a setting section 8 that selects the control function to be executed by the control section 7.
2. The input section 81 is composed of a numeric keypad and some function keys, and the setting section 82 is composed of a plurality of selection keys.

Here, in this embodiment, there are the following four types of control modes M1 to M4 as control functions selected by the setting section 82 and executed by the control section 7.

Ml: A call mode in which the telephone 4 is connected to the line and can be used.

M22 A transmission mode that executes the transmission procedure for facsimile transmission from the local station side.

M3: Polling mode for performing polling procedures.

M4: Automatic call/receive mode that automatically executes a series of operations from call origination to reception.

One of the modes M1 to M4 is selected by operating the setting section 2. Then, one of the selected modes is executed by the control section 7.

The operation of the facsimile machine configured as described above will be described below.

FIG. 2 shows a flowchart outlining the functions of the above-mentioned facsimile machine.

In the figure, when one of modes M1 to M4 is selected in the standby state (S1-S5), a procedure corresponding to the selected mode is executed (R1-R4). When the execution of the procedure is completed, the line is disconnected and the original standby state is returned (8)
6. SL).

FIG. 3 shows a flowchart outlining the automatic call reception procedure R4 executed when the automatic call reception mode M4 is selected.

In the figure, when automatic call reception procedure R4 is executed,
First, after connecting the line, an automatic calling operation is performed to call the communication partner selected in advance (S41.
542). When it is detected that the called communication party is connected to the line (S43), the device immediately enters the reception mode.

In this reception mode, first, a CED signal (called station confirmation signal) consisting of a 2100 Hz tone signal is sent to the communication partner, that is, the called side (S44). This allows the called side to know that the calling side, that is, the calling side, is ready to receive a facsimile. Furthermore, C.E.
After continuing to send the D signal for a certain period of time, the receiving side sends an NSF signal (non-standard function signal), a C3
It sends out an I signal (called terminal identification signal) and a DIS signal (digital identification signal).

Here, in response to the CED signal, 1. When the called side starts a facsimile transmission operation manually or automatically, the called side sends the parameters necessary for facsimile reception to the calling side. Therefore, the calling side determines the modem speed and performs phase matching in accordance with the parameters sent from the called side (S46). After this, the calling side sends a CFR signal (ready for reception signal) to the called side (
S47).

As a result, the device becomes ready to receive the image signal sent from the called side (S48). If an EOP signal indicating the end of the image signal is sent from the called side (S49
), a predetermined termination procedure is performed between the calling side and the called side to terminate the communication (S50).

As described above, by simply specifying the type of control function to be executed by the control unit 7 from the setting unit 82, the transition from call origination to reception is automatically performed. without special communication control procedures.
It is possible to automatically receive a facsimile from a communication party who has called the communication party from the own station side.

Thus, for example, if the called party's facsimile machine
If you have a service function that automatically sends a facsimile when you receive an incoming call, you will be able to receive that service function with very simple operating procedures.

Furthermore, even if the called party's facsimile machine does not have the above service functions, the called party can set the facsimile transmission status immediately upon receiving an incoming call, without having to have formal discussions between operators over the phone.
The calling side can receive facsimile transmission from the called side simply by setting the automatic call reception mode M4.

This is very effective in saving the labor of operation in the field where facsimile communication is frequently performed.

Effects of the Invention As is clear from the above explanation, the present invention provides a control means including a control function that automatically transitions to an image reception mode after the call operation by the automatic call function is completed, and a control means that the control means executes. and a setting section for specifying the control function to be executed, and by causing the control means to execute the control function according to the setting contents of the setting section, the type of control function to be executed by the control means can be specified via the setting section. , the transition from calling to receiving will be performed automatically, so you can call the other party from your own station and call the other party, without having to use special communication control procedures such as polling communication. This has the effect of greatly simplifying the operating procedure when receiving images from the called communication partner.
