2. Description of the Related Art A facsimile apparatus is a means for electrically transmitting document information to a remote place by using a telephone line or the like, and reading the document information by using a digital scanner or the like, encoding and compressing and transmitting it. Is the basic configuration.

By the way, recently, an interface for transmitting information created by a computer device such as a personal computer or a word processor via a facsimile device has been standardized (EIA standards Class 1 and 2). Along with this, a facsimile (FAX) control program conforming to these standard interfaces is provided.

In such a conventional apparatus in which a computer device and a facsimile device are connected, a facsimile is received when the computer device is powered off at the time of receiving a facsimile or when the FAX control program is not started on the computer device. The data is output by the apparatus or the received data is temporarily stored by using the image storage means of the facsimile apparatus, and then the FAX control program is started, and then the data is transferred to the computer apparatus.

[0005]

However, when receiving data created by a computer device, when the power of the computer device is off, or when the FAX control program is not running on the computer device, the facsimile machine is used. Even if the device tries to output, it is not image information because it is not image information.

Further, even in the case where the image information storage means in the facsimile apparatus stores the data, there are cases where the data cannot be stored when a large amount of data is sent. In this case, a communication error occurs after the memory is full.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a communication system for a facsimile apparatus, which allows the computer apparatus of the transmission destination to know the state of preparation for reception at an early stage and can take prompt action.

[0008]

SUMMARY OF THE INVENTION According to the present invention, when it is detected that the received data is data created by a computer device, the power of the computer device on the receiving side is turned off, or the fax is received. When the control program is not operating, the communication is terminated at the initial stage of communication.

[0009]

When the computer device on the receiving side is turned off at the time of transmitting data or the FAX control program is not operating, the communication is terminated at the initial stage of the communication. Therefore, the sender can detect that the data cannot be normally transmitted to the partner computer device early by the communication termination.

The personal computer 40 is a CP
Equipped with U, RAM, ROM and interface,
When the FAX control program starts up, data is exchanged with the facsimile device 30 via the interface section.

Next, the structure of the facsimile device 30 will be described. CPU 301 that controls the facsimile control unit
Is for controlling the entire facsimile in accordance with a control program stored in the ROM 302. As one of the controls, as will be described later, the communication is terminated in the initial stage of the communication when the personal computer 40 is powered off or the FAX control program is not operating.

A RAM 303 is connected to the CPU 301 to temporarily store image information data and the like. The reading unit 304 reads the document information with a digital scanner using a CCD or the like, the read image information is temporarily stored in the RAM 303, and the image information is stored in the CPU 3
At 01, the data is encoded and compressed, and sent from the facsimile modem 308 and the line control unit (NCU) 309 to the telephone line.

The modem 308 modulates image information data (encoded data) and the like into a signal suitable for a telephone line, and
Demodulates the modulated signal from the telephone line. CPU 301
Decodes the demodulated signal during facsimile communication,
This is output to the recording unit 306.

The recording unit 306 executes printout based on the decoded image information (image information). On the other hand, the image information storage unit 305 stores image information data (coded data) to be transmitted, received image information data, or the like.
