Abstract

PURPOSE:To discriminate automatically an FAC (facsimile device) being an opposite communication party by providing a means discriminating whether or not a group identification signal is incoming within a predetermined constant time to a facsimile controller after the receiving of the identification signal of a called station. CONSTITUTION:A document data is inputted to a memory in an FA(facsimile adaptor) once via a channel and a channel interface from a host computer. A microprocessor (MPU) in the FA controls the operation of each section by the program control. The transmission step between the FA and the FAX is performed via an MODEM in the FA. A character pattern generator is a circuit converting a document data inputted to the memory in the FA into dot pattern and acts also like generation of dot data at each scanning line of the FAX and superimposing the data on a carrier.

Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to a facsimile connection control system, and in particular, the present invention relates to a facsimile connection control system that connects to a data processing device and converts data sent from the data processing device into a facsimile signal to communicate with a communication partner. The present invention relates to a facsimile connection control system that automatically identifies the type of facsimile device of a communicating party and executes a predetermined control procedure in a facsimile output control device for outputting to a facsimile device.

(b) Prior Art and Problems FIG. 1 shows a system configuration when document data held by a computer, which is a data processing device, is outputted as image data to a facsimile machine (FAX).

Document data held by a computer is composed of character codes, and is sent to a facsimile adapter (FA) through a channel. The FA converts the character code into image data consisting of a dot pattern and sends it to the FAX, so that document data on the computer can be faxed as image data.
will be output to .

Here, as a FAX for analog signal formation, 02F-AX
There are so-called mini-FAXes, but since these have different connection procedures, conventionally it was necessary to instruct the F'A on the computer side which one to output to.

Therefore, in a system that connects both G2 FAX and mini FAX, there is a problem that control on the computer side becomes complicated.

(c) Purpose of the Invention The present invention provides a facsimile adapter (FA), which is a facsimile output control device, to automatically output a fax to a communication partner.
The purpose is to make it possible to identify the type of document data, and to enable a computer program to control only the output of document data.

In order to achieve the above object, the present invention provides a facsimile output control system which is connected to a data processing device, converts data sent from the data processing device into a facsimile signal, and outputs the signal to a facsimile device of a communicating party. A device, when a call is received, t
A first type of facsimile device configured to send a called station identification signal to the called device and also send a group identification signal after sending the called station identification signal; Sending wave In a facsimile output control device that is connected to a second type of facsimile device that is configured to wait for a predetermined signal from a destination device without transmitting the group identification signal, the called station identification signal is received. and a means for determining whether or not the group identification signal has arrived within a predetermined period of time, and when the determination means determines that the group identification signal has arrived, the other device is of the first type. When the arrival of the group identification signal is not determined, the other party's device is regarded as a facsimile machine of the second type and the subsequent control procedure operations are executed. It is characterized by having been configured.

(e) Examples of the invention The present invention will be explained below with reference to the drawings.

First, transmission control procedures for G2 FAX and mini FAX will be explained. FIG. 2 shows the transmission procedure when image data is output from the FA to the G2F-AX, and FIG. 3 shows the transmission procedure when the image data is output from the FA to the mini-FAX.

In Figures 2 and 3, CED is the called station identification signal, G
■ is a group identification signal, GC is a group command signal, CF
R is a reception ready signal, EOM is a message end signal,
MCF is a message confirmation signal.

The operation when outputting image data from FA to G2FAX is as follows.

■Dial the receiving side from the sending side (FA).

When the receiver hooks on and presses the communication button, a CED signal is sent to the transmitter.

■After receiving the CED signal, the transmitting side receives the next GI double signal 30
Wait ~40 seconds.

From the GI double signal, the sending side knows that the other party's FAX is G2F-AX.

■The transmitting side transmits the GC signal after receiving the GI signal.

After the GC transmission, a phase signal is transmitted for phase synchronization of the image signal.

■When the receiving side receives the phase signal and completes phase alignment, it sends the CFR signal.

(2) When the transmitting side receives the CFR signal, it sends an image signal and transmits image data.

When the image signal ends, the transmitting side sends an EOM signal.

(2) When the receiving side receives the EOM signal, it performs page end processing and then sends the MCF signal.

Next, the operation when outputting image data from the FA to the mini-FAX is as follows.

■Dial from the sending side (EA) to the receiving side (mini-FAX).

When the receiving side hooks on and presses the communication button, a CED signal is sent to the transmitting side.

■When the transmitting side receives the CED signal, it sends a phase signal to align the phase of the image data.

■The receiving side receives the phase signal, and when the phase alignment is completed, sends the CFR signal.

■The image data is then transmitted using the same procedure as in the case of G2 FAX.

FIG. 4 is a diagram showing the operation flow of the FA according to the embodiment of the present invention. In the embodiment, the G2FA is implemented by executing the following steps under the program control of the MPU.
I try to differentiate between X and mini F'AX. That is, (1) If the CI double signal is received within 20 seconds after receiving the CED signal, the other party's FAX is designated as a G2 FAX and the subsequent steps are taken.

■If the GI double signal does not arrive within 20 seconds after receiving the CED signal, assume that the other party's FAX is a mini-FAX, send the phase signal, and take the subsequent transmission procedure.

■If the 02FAX does not send the GI double signal within 20 seconds and sends the GI double signal after 20 seconds, the FA will send the other party a mini FAX signal.
Since the response procedure is based on the assumption that it is an AX, it is not possible to make a correct response to the G2FAX. In this case, since the CFH reception frequency is 1080 Hz, the CF'R from G2FAX cannot be received, the line can be disconnected as a FAX error, and no further abnormal operation will occur.

In the example, the G2 reception waiting time was set to 20 seconds because: ■ In the case of a mini FAX, the time from receiving the CED to transmitting the phase signal is at most 30 seconds; ■ If the G2 FAX is a manual reception, This is based on the fact that 20 seconds is sufficient until the communication button is pressed. Therefore, the setting of the GI reception waiting time can be changed freely to some extent as long as it is within 30 seconds.

FIG. 5 is a block diagram of the FA of the embodiment.

Document data is sent from the host computer via the channel and channel interface to the FA.
is input into memory within. In the FA, a microprocessor (MPU) controls the operation of each part under program control.

The transmission procedure between the FA and FAX is performed via a modem within the FA.

In other words, both the GC signal phase signal and the EOM signal sent from the FA to the FAX are transmitted from a 2100Hz transmitter to M
It is created by operating from PU.

In addition, the CED signal sent from F'AX to FA, G-
