5 is temporarily stored. Further, the CPU 82 transmits the received image data and the read image data to the cut sheet 56.
When recording on the upper side, a cut sheet 56 of a size suitable for recording the image data is selected from the cut sheet supply unit 15.

As shown in FIG. 3 and FIG.
When the sub-scanning length M1 of the received image data exceeds the main scanning width M2 of the cut sheet 56 when the received image data is to be rotated by 90 degrees and is to be recorded on the cut sheet 56,
The recording mode of the received image data is selected. That is, the over-scan portion M1a is added to the sub-scan length M1 of the received image data
Exists, the sub-scanning length M1 and the main-scanning width M2
The recording mode is changed in accordance with the difference. If the difference is equal to or less than the predetermined value, the over-part discard mode or the rotation reduction mode is performed based on the detection result of the number of black and white conversion points in the over-part M1a and the setting status of the reduction setting key 87c. The received image data is recorded on the cut sheet 56.

Here, the over-portion discarding mode is to discard the data of the over-portion M1a and record the received image data in a rotating state on the cut sheet 56. In the rotation reduction mode, the whole area of the received image data is rotated and reduced at a predetermined reduction rate, for example, about 90%, and is recorded on the cut sheet 56.

Next, the operation when the image data or the like received by facsimile communication is recorded on the cut sheet 56 in the copy / facsimile multifunction peripheral of this embodiment will be described with reference to FIG.
This will be described based on the flowchart shown in FIG. This flowchart proceeds under the control of the CPU 82 based on a control program stored in the ROM 83.

Now, a standard size (for example, A4R size)
When one page of image data having a longer sub-scanning length is received, the image data is temporarily stored in the image memory 85 in a non-rotated state (image data before rotation) (S1). Then, the sub-scanning length M1 of the received image data is obtained (S2). The sub-scanning length M1 of the received image data is the first
Main scanning width M21 of the cut sheet 56 in the sheet cassette 57 of FIG.
It is determined whether or not it is within + threshold T1 (S
3).

Here, the threshold value T1 is a virtual scanning width set in a portion of the cut sheet 56 that exceeds the main scanning width M2, as shown in FIG. That is, by judging whether or not the over-portion M1a of the sub-scanning length M1 of the received image data is equal to or smaller than the threshold value T1, when recording the image data by rotating it 90 degrees, the sub-scanning length M1 It is determined whether the difference between the width and the main scanning width M2 is equal to or smaller than a predetermined value. Note that the threshold value T1 is usually set by an input operation from the operation unit 87 when the device is shipped from a factory.
It is set to, for example, 24 mm in a range of 0 to 84 mm.

Here, when it is determined that the sub-scanning length M1 exceeds the value of the main scanning width M21 + the threshold value T1, the sub-scanning length M1 is subsequently cut in the second sheet cassette 57. It is determined whether it is within the main scanning width M22 of the paper 56 + the threshold value T1 (S4). Further, if it is determined that the sub-scanning length M1 exceeds the value of the main scanning width M22 + the threshold value T1, the n-th sheet cassette 5
The same determination is performed up to 7 (S5). In this case, the width of the cut sheet 56 is the first sheet cassette 5.
It is loaded so as to be larger from the seventh to the n-th paper cassette 57.

When it is determined that the sub-scanning length M1 exceeds the value of the main scanning width M2n of the cut sheet 56 in the n-th sheet cassette + the threshold value T1, the pre-rotation image data is subjected to the rotation processing. The printing process is executed in the normal mode without being performed (S6). At this time, the CPU 8
2 selects a cut sheet 56 on which the entire area of the received image data is recorded. Then, the process ends.

For example, as shown in FIG. 5, the sub-scanning length M1 of the received image data is longer than the standard size of A4R.
Consider a case where the sub-scanning length M1 exceeds the main scanning width M2 of any of the cut sheets 56 + the threshold value T1. In this case, the entire area of the received image data is recorded on the cut sheet 56 of A3 size without being subjected to the rotation processing.

On the other hand, if it is determined in S3 to S5 that the sub-scanning length M1 of the received image data is equal to or smaller than the sub-scanning width M2 of one of the cut sheets 56 + the threshold value T1, the image data is rotated by 90 degrees. The image data is stored in the image memory 85 in the state (rotated image data) (S7).

Then, for the threshold value T1, the number of black-and-white conversion points of the received image data is detected, and it is determined whether the number of black-and-white conversion points exceeds a predetermined value (S8).
In S8, the threshold value T1 of the rotated image data is set.
If the portion is almost blank, the number of the black and white conversion points is determined to be less than or equal to a predetermined value. In this case, the image data in the portion of the threshold value T1 of the rotated image data is discarded, and the print processing is executed in the over-partial discard mode (S9), and the processing ends.

For example, as shown in FIG. 6, although the received image data is slightly longer than the A4R size, it is smaller than the main scanning width M2 of the A4 size cut sheet 56 + the threshold value T1, and the threshold value T1 portion is Consider the case where there is almost no margin. In this case, the threshold T1 portion,
In other words, the data of the over part M1a exceeding the A4R size is discarded. Then, the received image data is recorded on the A4 size cut sheet 56 in a rotating state.

On the other hand, in S8, when the image continues up to the threshold value T1 of the rotated image data, it is determined that the number of the monochrome conversion points exceeds a predetermined value. In this case, it is determined whether or not the rotation reduction printing of the document image data is set by the reduction setting key 87c of the operation unit 87 (S10). If the rotation reduction printing is set, the entire area of the rotated image data is reduced at a predetermined reduction ratio, the printing process is executed in the rotation reduction mode (S11), and the process ends.

For example, as shown in FIG. 7, although the received image data is slightly longer than the A4R size, the received image data is smaller than the width of the A4 size cut sheet 56 + the threshold value T1. Consider the case where it is continued.
In this case, the entire area of the received image data is recorded on the A4 size cut sheet 56 in a state where the entire area is reduced and rotated at a reduction ratio of, for example, about 90%.

The effects that can be expected from the above embodiment will be described below. In the communication terminal device of this embodiment, when the received image data has an over-portion M1a exceeding the width of the cut sheet 56 to be recorded in a state where the length is rotated by 90 degrees, the over-portion M1a A mode suitable for the situation of the image data is selected. Therefore, it is possible to select a cut sheet 56 suitable for each mode. Therefore, the cut sheet 56 on which the received image data is recorded
Can be prevented from being given a large margin,
The cut sheet 56 can be used effectively without waste. In the communication terminal device of this embodiment, the above-mentioned over-portion M1a exists in the received image data, and the over-portion M1a
Is within the predetermined threshold value T1 and is almost blank, the received image data is recorded on the cut sheet 56 in the over-partial discard mode. In other words, the received image data is recorded on the cut sheet 56 in a rotated state, with the data of the over-portion M1a where almost no image is present being discarded. For this reason, when recording the received image data on the cut sheet 56, it is possible to suppress the formation of a large margin on the cut sheet 56, and
Can be used effectively without waste.

In the communication terminal device of this embodiment, the received image data has the over-portion M1a, the over-portion M1a is within a predetermined threshold value T1, and the image continues even in the over-portion M1a. In such a case, the received image data is recorded on the cut sheet 56 in the rotation reduction mode. That is, the received image data is recorded on the cut sheet 56 while the entire area is rotated and reduced at a predetermined reduction rate. here,
Since the reduction ratio may be set to such an extent that the entire area of the received image data including the narrow threshold T1 can be recorded,
The reduction ratio can be set to, for example, a value of about 90%. Therefore, the received image data is only slightly reduced, and a large margin is not formed on the cut sheet 56.
The entire area can be recorded and reproduced. In addition, it is possible to prevent data that needs to be recorded existing in the over-portion M1a from being carelessly discarded.

In the case where the received image data of this embodiment includes the over-portion M1a and the over-portion M1a exceeds a predetermined threshold T1, the received image data is recorded on the cut sheet 56 in the normal mode. It is supposed to. Further, as described above, even when the over portion M1a is within the predetermined threshold value T1 and the image continues even in the over portion M1a, the reduction setting key 87
When C is set to off, recording is performed in the normal mode similarly. That is, the entire area of the received image data is recorded on the cut sheet 56 without being rotated. Therefore, for example, even when there is no cut sheet 56 that can be recorded in the rotating state, or when it is desired to avoid recording in the rotating state, the entire area of the received image data can be recorded.

The above embodiment can be embodied with the following modifications. The control program recorded on the recording medium 91 is read into the RAM 84 by the recording medium reading unit 90 via the CPU 82, and the CPU 82 is configured to execute the operation of the communication terminal device described in the embodiment. In such a configuration, for example, using a personal computer including a modem 88 and an NCU 89, and a printer that performs the functions of the cut sheet supply unit 15 and the recording unit 17, substantially the same effects as those of the communication terminal device of the above embodiment are obtained. Can be demonstrated.

In the flowchart shown in FIG. 4 of the embodiment, if the rotation reduction printing of the image data is not set in the determination of S10, the printing process is executed in the over-partial discard mode. thing. With this configuration, when the received image data is rotated, the original pre-rotation image data can be immediately deleted, and the capacity of the image memory 85 can be reduced.
