Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image communication apparatus connectable to a data processing apparatus (hereinafter referred to as "host") such as a personal computer.

[0002]

2. Description of the Related Art Conventional facsimile machines have been provided which are capable of switching between an "automatic" mode, an "absent" mode, and a "manual" mode in response to an instruction from an operating section.

In the "automatic" mode, the communication control unit monitors a calling signal (hereinafter referred to as CI) from the line, and when the CI is detected, the line is automatically captured and the facsimile reception procedure is immediately started. Mode. Also, in the "absence" mode, the communication control unit monitors the CI from the line,
When the CI is detected, the line is automatically captured, when the CNG signal is detected, the receiving means of the facsimile is immediately started, and when the CNG signal cannot be detected for a certain period of time, the communication control unit externally operates. In this mode, the pseudo CI is sent to the telephone connected to the telephone (hereinafter, simply referred to as telephone), and when the off-hook of the telephone is confirmed, the communication control unit is controlled to connect the line to the telephone. Further, the "manual" mode is a mode in which the communication control unit controls the communication line so that the line is directly connected to the telephone and the communication control unit does not monitor the CI.

In such a facsimile apparatus, a "memory" mode in which received data is stored in the RAM as image data without recording the received image according to an instruction from the host, and the received data is stored in the RAM as image data. It is possible to switch between the "memory + print" mode in which the recording unit records the received image by the recording unit and the "normal" mode in which the recording unit records the received image and the received data is erased from the RAM after recording. Things are offered.

Conventionally, the selection of the reception mode according to the instruction from the operation unit and the selection of the reception mode according to the instruction from the host are independent of each other, and in any case, the reception mode according to the instruction from the operation unit is used. However, the reception mode instructed by the host can be freely changed, and thus the reception mode instructed by the operation unit is not changed.

[0006]

By the way, when the user changes the receiving mode instructed by the host to "automatic", the user automatically captures the line when the call signal is detected and the received data is received. It seems to expect to receive it automatically from the host.

However, if the reception mode instructed by the operation unit and the reception mode instructed by the host are independent from each other as in the conventional case, the reception mode instructed by the operation unit becomes "manual". If so, the received data cannot be automatically received from the host.

According to the present invention, when an instruction to change the receiving mode is issued by the host, the state of the receiving mode is confirmed by the instruction from the operation unit, and then the receiving mode is changed by the instruction from the host. It is an object of the present invention to provide a facsimile apparatus that can accept and change the reception mode instructed by the operation unit in response to the request.

[0009]
