Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for transmitting document information according to a predetermined transmission mode.

[0002]

2. Description of the Related Art When a manuscript is set in a facsimile machine and the manuscript information is transmitted to a facsimile machine on the receiving side via a telephone line, for example, the manuscript information of the first sheet is transmitted in a normal mode of normal image quality, If the transmission mode is changed to the fine mode during the transmission of the second document, images of good quality can be transmitted for the second and subsequent documents. However, if the facsimile machine on the receiving side does not have the ability to process the document information in the fine mode, the transmission mode is automatically set to the normal mode to transmit an image of normal image quality.

[0003]

If the facsimile machine on the receiving side does not have a receiving capability suitable for this even if an attempt is made to change the transmission mode of the original on the next page to the fine mode during transmission of the original, the conventional facsimile machine is It automatically corrects to normal mode and sends normal image quality images. Therefore, the operator notices that the original cannot be transmitted in the fine mode only after actually transmitting the original, and there is a problem that the transmission mode suitable for the receiving side cannot be freely selected in advance. Further, since the size of the recording paper set on the receiving side is unknown on the transmitting side, the size of the original and the recording paper may be different between the transmitting side and the receiving side during the transmission of the original, and proper facsimile communication is performed. There was also the problem of not being able to do it.

[0004]

In order to solve such a problem, the present invention stores a capability information of a receiving side device received at the start of transmission of a document and displays the capability information, and a document. Detection means for detecting the presence / absence of a transmission mode change instruction each time transmission of one line is completed, determination means for determining whether or not a change is possible based on the capability information when a transmission mode change instruction is detected, and this determination And means for displaying a message when the means determines that it is not.

[0005]

When the transmission of the original is started, the capability information received from the receiving side device is displayed, and a message is displayed when the change of the transmission mode is instructed during the transmission of the original and it is determined that this is not the case.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the facsimile apparatus of the present invention. In the figure, 1 is a CPU for controlling the entire facsimile apparatus, 2 is a modem for transmitting image information of an original or the like, 3 is an image sensor for reading the information of the original, 5 is a print head, and 5 is image information. A mode change switch for instructing whether to transmit in fine mode with good image quality or normal mode with normal image quality, 6 is a dial key, 7 is a communication key for transmitting image information, 8 is a memory, 9 Is a display unit for performing various displays, 11 is a speaker, L is a telephone line, and SW is a switch for closing a DC loop of the telephone line L.

When transmitting image information such as a document to a facsimile machine on the receiving side by using such a facsimile device, first, the document is set at a predetermined position and the dial key 6 is operated to input a partner number. Then, when the communication key is subsequently pressed, the switch SW is turned on to close the telephone line L, and the dialed number of the input partner is sent to the line L. Then, when the receiving side facsimile device is called and the receiving side facsimile device responds to the call, the image information of the document read by the image sensor 3 is transferred to the modem 2
Is transmitted to the facsimile apparatus on the receiving side in a predetermined transmission mode.

Next, FIG. 2 is a flow chart showing the operation of the CPU 1 in the facsimile machine. The detailed operation of the facsimile apparatus of the present invention will be described based on this flowchart. In the case of transmitting document information in a transmitting facsimile device (hereinafter, transmitting device), when a document is connected to a receiving facsimile device (hereinafter, receiving device), a DIS signal is transmitted from the receiving device. This DIS
The signal is, for example, a digital identification signal composed of parameters such as the transmission speed of the modem, the sub-scanning line density, and the two-dimensional coding capability, and the capability of the receiving side device (capability information of the receiving side device; that is, in the fine mode in this case). Capacity for receiving images or size information of recording paper). Step 5
In the case of 0, it is first judged that the DIS signal is received from the receiving side device, and if this is received and judged as "Y", the parameter of the received DIS signal is stored in the memory 8 (step 51). Then, the transmission mode is set to the DCS parameter described later (step 52), and the DCS signal is transmitted to the receiving side device in step 53.

The DCS signal is a signal for instructing the receiving side device in response to the DIS signal, such as the transmission speed of the modem, the sub-scanning line density, and the two-dimensional coding capability. Then, in step 54, a TCF signal is transmitted to the receiving side device to check whether the line can be used at the designated modem speed, and a CF indicating a normal reception for this TCF signal is sent.
Reception of the R signal or the FTT signal indicating abnormal reception is determined in steps 55 and 56, respectively.

When the FTT signal is received from the receiving side device, it means that the TCF signal is abnormally received, and therefore the process returns to step 52 to transmit the DCS signal again, and when the CFR signal is received, the process proceeds to step 57. Step 5
At 7, the DIS parameter received from the receiving device is displayed on the display unit (LCD display) 9. Examples of the display of this are "Other party's A4 recording paper.", "Other party's fine ability is not available."

Next, at step 58, the image sensor 3
1 line of the original is read by this and this information is transmitted to the receiving side device via the modem 2, and it is judged in step 60 whether or not there is an instruction to change the transmission mode. DIS stored in
In step 61, it is determined whether the transmission mode can be changed based on the parameter. If the transmission mode cannot be changed, the warning buzzer sounds, that is, the warning sound is sent from the speaker 10 (step 62), and the display unit 9
Display a mode change rejection message (step 6)
3). Examples of display of this refusal message include, for example, "B4 size cannot be sent." And "Fine cannot be sent." After that, the transmission mode is automatically corrected, for example, the transmission mode instructed to the fine mode is automatically corrected to the normal mode as before (step 64), and the process proceeds to step 65.
If there is no instruction to change the transmission mode (step 60
If the answer is "N" in step 1) and if the transmission mode can be changed (if "Y" in step 61), the process proceeds to step 65.

In step 65, it is judged whether or not the manuscript information has been transmitted up to the final line. If the manuscript information is "N", the process returns to step 58 to read and transmit the next one line, and the manuscript information is finally transmitted. Once the line is done,
The process proceeds to step 66 and it is determined whether or not there is a next original. Then, if there is the next original to be transmitted, it is judged again in step 67 whether or not the change to the instructed transmission mode is possible. If it is "N", the next page of the original is determined in step 68. There is an MPS signal indicating that there is a change in the transmission mode to the receiving side device, the MCF signal from the receiving side device is received in step 69, and the process returns to step 57 to display the DIS parameter and the next page. Send the manuscript information of.

When it is judged that the change to the instructed transmission mode is possible and it is judged "Y" in step 67, an EOM signal for ending the message is sent to the receiving side device in order to change the transmission mode. Send (Step 7
0) After receiving the MCF signal as the confirmation signal from the receiving side device (step 71), the process returns to step 50 to receive the DIS signal again, and transmits from the first line of the original on the next page. Thus, the manuscript information of each page is sequentially transmitted line by line to the receiving side device. As a result, when there is no manuscript to be transmitted and it is judged as "N" in step 66, an EOP signal indicating the end of the manuscript information transmission is sent. At the same time as transmitting to the receiving side device (step 72), after confirming the MCF signal from the receiving side device (step 73), a DCN signal indicating a disconnection command is transmitted to the receiving side device (step 74), and the process ends.

As described above, according to the present invention, the DIS parameter (capacity information) from the receiving side device is displayed on the display unit 9 at the start of the document transmission to notify the state of the receiving side device and its receiving ability, and the original document is transmitted. When it is determined during transmission that the change to the instructed transmission mode is impossible, the speaker 10 is caused to emit a warning sound and the display unit 9 is so displayed.

[0015]

As described above, according to the present invention, the capability information received from the receiving side device is displayed at the time of starting the transmission of the document, and the change of the transmission mode is instructed during the transmission of the document, and it is judged that this is not the case. In this case, since the message is displayed, the capability of the receiving side device can always be confirmed at the transmitting side, and therefore, the transmitting mode can be set appropriately according to the receiving side.
