Abstract

PROBLEM TO BE SOLVED: To prevent recording paper from being used futilely by setting an originator information to be added to the head part of image information to the inside of the image information. SOLUTION: A signal whose signal level is 1 is outputted from a control circuit 20 to a signal line 20a to set a CML. Then 44-th bit and 45-th bit of an FIF of a DIS signal are checked so as to discriminate which of the inch system resolution or the metric system resolution is required. When the bit 44 is '1', that is, the inch system resolution is required, the bit 44 of the DIS signal is set to '1' to designate the inch system resolution, and the originator information is added to the outside of image information and the resulting image is sent. On the other hand, when the bit 45 is '1', that is, the metric system resolution is required, the bit 44 of the DIS signal is set to '0' to designate the metric system resolution and the sender information is added to the inside of image information in a succeeding step and the transmission of image is 440dpi×400dpi is conducted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for reading and communicating in an inch system in both the main scanning direction and the sub scanning direction.

[0002]

2. Description of the Related Art A conventional facsimile apparatus is 8 pel / mm or 16 pel / mm in the main scanning direction according to the recommendation.
And 3.85 line / mm or 7.7 in the sub-scanning direction.
Communication was performed at line / mm or 15.4 line / mm. These are communications based on the mm system. Here, for example, the image information read (depending on the resolution of the scanner) at 400 dpi in both the main scanning direction and the sub-scanning direction is read by the partner receiver set in the main scanning direction 16 pel / mm and the sub-scanning direction 15.4 line / mm. When you send
On the partner receiver side, (400/25.
4) /16=0.984 times, which is (4
00 / 25.4) /15.4=1.023 times.

On the other hand, in (main scanning direction, sub-scanning direction),
(400 dpi, 400 dpi), (200 dpi, 2
00 dpi) and (300 dpi, 300 dpi) can be set by a communication procedure at a resolution, which is called inch-based communication.

[0004]

However, in the above-described conventional example, since it is 1.023 times in the sub-scanning direction, it takes about 6.8 mm longer when considering transmitting an A4 size original. . Due to the increase of 6.8 mm, there is a problem that the recording paper is wasted when the other receiver side records on a cut paper and is divided and printed on two sheets.

The present invention has been made in view of the above problems of the above-mentioned conventional technique, and an object of the present invention is to provide a facsimile apparatus which eliminates the waste of recording paper. To do.

[0006]

In order to achieve the above object, a facsimile apparatus according to a first aspect of the present invention is arranged so that when image data is read and communicated in inches in both the main scanning direction and the sub-scanning direction, communication is performed. The present invention is characterized in that a control means for controlling the sender information added to the tip end portion to be inside the image information is provided.

Further, in order to achieve the above-mentioned object, claim 2
When the facsimile device described above is used for reading and communicating in the inch system in both the main scanning direction and the sub-scanning direction, and when the counterpart receiver notifies that the inch system communication is requested, When the sender information to be added to the tip of the image information is outside the image information and the partner receiver notifies that the communication request is for millimeter (mm) communication, the sender information is included inside the image information. It is characterized in that a control means for controlling so as to provide is provided.

Next, in step S208, the pre-procedure is executed, and step S
At 209, 44 bits and 45 bits of the FIF of the DIS signal are checked to determine whether the inch (inch) resolution or the millimeter (mm) resolution is requested. If the bit 44 is "1", that is, if the resolution of the inch system is requested, the process proceeds to step S210, and the bit 44 of the DIS signal is set to "1".
, The resolution of the inch system is designated, and in the next step S211, the sender information is added to the outside of the image information and the image transmission of 400 dpi × 400 dpi is performed, and then the process proceeds to step S301 of FIG. Then, after the post-procedure is executed, the process returns to step S201.

On the other hand, when the bit 45 is "1" in step S209 of FIG. 2, that is, when the resolution of the millimeter (mm) system is requested, the process proceeds to step S401 of FIG. 4 and the bit 44 of the DCS signal is set to "0". As a millimeter (m
m) system resolution is specified, and in the next step S402, the sender information is added to the inside of the image information and 400 dpi × 4.
After performing the image transmission of 00 dpi, the next step S40
After performing the post-procedure in 3, the process returns to step S201 in FIG.

As described above, according to the facsimile apparatus of this embodiment, if the transmitter is 400 dpi in both the main scanning direction and the sub scanning direction, and the receiver is 400 dpi in both the main scanning direction and the sub scanning direction. Since the image information is not expanded, the sender information is added to the outside of the image information to eliminate the loss of the image information, and the receiver is 16p
If el / mm and 15.4 line / mm in the sub-scanning direction, the sender information is added to the inside of the image information to prevent the receiver from recording separately on two sheets of standard paper size. It has become possible.

(Second Embodiment) Next, the second embodiment of the present invention will be described.
The embodiment will be described with reference to FIG. The present embodiment is a facsimile apparatus that performs reading, communication, and recording in inches in both the main scanning direction and the sub-scanning direction.
The sender information added to the tip of the image information is always inside the image information.

FIG. 5 is a flow chart showing the operation control procedure of the facsimile apparatus according to this embodiment. Figure 5
Since Steps S501 to S508 are the same as Steps S201 to S208 of FIG. 2 in the above-described first embodiment, description thereof will be omitted, and only processing steps specific to this embodiment will be described.

After the pre-procedure is executed in step S508 of FIG. 5, the process proceeds to step S509, the sender information is added to the inside of the image information, and 400 dpi × 400 dpi is added.
After the image transmission is performed, the post-procedure is executed in the next step S510, and then the process returns to step S501.

As described above, according to the facsimile apparatus according to the present embodiment, the sender information added to the leading end of the image information is always inside the image information. Both the scanning direction is 400 dpi, the receiver is 16 pel / mm in the main scanning direction and 1 in the sub-scanning direction.
Even at 5.4 lines / mm, for example, the information on the A4 standard paper size can be recorded on one recording sheet of the A4 standard paper size.

[0023]

As described above in detail, according to the facsimile apparatus of the first aspect of the present invention, the sender information added to the leading end of the image information is inside the image information.
Transmitter is 400 dpi in both main and sub scanning directions
Thus, even if the receiver is 16 pel / mm in the main scanning direction and 15.4 line / mm in the sub-scanning direction, for example, the information on the standard paper size of A4 can be recorded on one recording paper of the standard paper size of A4. The effect is possible.

Further, according to the facsimile apparatus of claim 2 of the present invention, when the receiver notifies that the inch communication is preferable, the sender information is added to the outside of the image information and the image information of the image information is added. If there is no omission and the receiver notifies that millimeter communication is preferable, the sender information is added to the inside of the image information, so it is recorded separately on the recording paper of two standard size sheets at the receiver side. The effect of being able to prevent it is exhibited.
