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 image information with transmission source information added thereto.

[0002]

2. Description of the Related Art Conventionally, source information added to an image signal is
Either put it inside the image information (overwrite the image information), put it outside the image information (shift the image information and insert it), depending on the device, it is fixedly set, or it can be set by either switch means It can be selected and set. Here, even in the latter case, the addition method once selected is fixedly used unless the state of the switch means is changed.

[0003]

Therefore, the following inconveniences have conventionally occurred.

For example, in an apparatus configured or set so as to add the source information to the outside, the source information is added to the outside even though the other party's recording paper is a fixed size paper, There is a disadvantage that image information is shifted and information at the rear end cannot be recorded.

Further, in an apparatus configured or set so as to add the source information to the inside, the source information is added to the inside even if the other party's recording paper is not of the standard paper size, and the information at the leading end is added. There is a drawback that the information at the tip becomes invisible because of the overlap.

Therefore, it is conceivable to limit whether source information is added to the inside or outside based on, for example, the FIF (facsimile information field) bit 20 of the DIS signal (no maximum length of paper). . But,
There are many machines that perform long-length processing on the receiver side, and even if the recording paper is a fixed size paper, the bit of the FIF of the DIS signal
There is hardly any machine for setting 20 to 1, and there is a drawback that practicality is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus capable of appropriately selecting a source information adding method according to the state of recording paper in a receiver.

[0008]

According to the present invention, there is provided a registration means for registering information indicating whether or not a recording sheet on the receiver side is a cut sheet and a recording sheet size corresponding to a one-touch dial or a speed dial. Have, one-touch dial,
Or, if calling is selected by speed dial,
Refer to the information indicating whether the recording paper registered for the one-touch dial or the speed dial is a cut sheet, and if it is a cut sheet, add the sender information inside the image. If the sheet is not a cut sheet, the sender information is added to the outside of the image.

Even if the recording paper registered corresponding to the one-touch dial or the abbreviated dial is a cut paper, if the sub-scanning length of the document information is equal to or less than a predetermined length, the transmission source information is replaced with the image. It shall be added to the outside. Here, the sub-scanning length of the document information may be determined based on the effective information length. Further, whether to add the transmission source information inside the image or outside the image may be unified in one communication.

In the above, the receiver has means for notifying the transmitter of information indicating whether the recording paper is cut paper and information designating the dividing process on the transmitter. When the transmitter indicates that the recording paper is cut paper, or when the transmitter specifies division processing, the recording paper registered corresponding to the one-touch dial or speed dial is cut. Regardless of the information indicating whether or not the sheet is a sheet, the recording sheet of the partner machine is determined to be a cut sheet, and the subsequent control is executed.

As described above, when the recording paper of the receiver of the other party is a cut sheet of the same size as the original to be transmitted, the transmission source information can be added inside the image information. No more splitting.

Further, transmission to a destination using roll paper,
Alternatively, even if the sub-scanning length of the source information is added to the length of the image information in the sub-scanning direction, in the case of transmission to a destination that fits on one cut sheet, the source information is outside the image information. Is transmitted in addition to the image information, so that the source information does not overlap with the image information and the image information cannot be read.
