BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device having a communication function such as facsimile communication, a copying function, and a printer function, and a program for causing a computer to execute the functions in the communication terminal device. It relates to a recorded program recording medium.

[0002]

2. Description of the Related Art A communication terminal device of this type is known which has a function of suppressing the generation of an unnecessary margin on a recording sheet by rotating original image data by 90 degrees and recording the image on recording sheet. Have been. In this conventional apparatus, original image data received by facsimile communication or the like is temporarily stored in an image memory in a state of being rotated by 90 degrees,
The data is recorded on recording paper.

[0003]

Generally, in facsimile communication, a rectangular pixel having a size of 8 dots / mm in the main scanning direction and 7.7 lines / mm in the sub-scanning direction is used. By the way, in such facsimile communication, when the image data is encrypted, for example, the following method is known. That is, the document image data is divided by meshes of a predetermined size, and the image data of each mesh portion is randomly replaced, thereby encrypting. Then, the encrypted data is transmitted from the calling side to the called side together with the coordinate axes. Here, as described above, since each pixel is a rectangle instead of a square, simply rotating the encrypted data by 90 degrees causes distortion in the aspect ratio. When decoding is performed based on the coordinate axes, the original position information may be deviated, and it may be difficult to perform accurate decoding.

In the conventional communication terminal device described above, when document image data needs to be rotated, a rotation process is performed regardless of the type of the document image data. For this reason, when the document image data is encrypted data received by facsimile communication or the like, there is a problem that the data is subjected to rotation processing, and as described above, decryption may be difficult.

[0005] Further, in the conventional communication terminal device, when receiving the encrypted data, the data may be recorded and stored on a recording paper as it is without being decrypted. In this case, the encrypted data on the recording paper is read by a scanner when decryption is necessary, and decrypted based on a predetermined keyword. If the encrypted data is rotated during the decryption, it is difficult to decrypt and an accurate image cannot be obtained even if the scanner or the like has a certain degree of distortion correction function.

Further, even when the original image data is confidential reception data or polling reception data in facsimile communication or the like, if the original image data is rotated, it takes a long processing time, and the operator has to wait. Was.

The present invention has been made by paying attention to such problems existing in the prior art. The purpose is to determine whether or not the data can be rotated according to the type of the document image data. For example, it is difficult to decrypt the encrypted data due to the rotation of the encrypted data. It is an object of the present invention to provide a communication terminal device and a program recording medium that can suppress occurrence of the risk of becoming.

Select from 5.

Next, an operation of setting a user setting bit of the table data T1 in the copy / facsimile / printer multifunction peripheral of this embodiment will be described with reference to a flowchart shown in FIG. Note that this flowchart proceeds under the control of the CPU 82 based on a control program read from the recording medium 91 by the recording medium reading unit 90 and stored in the ROM 83.

When the type of the document image data is designated by operating the operation unit 87 (S1), it is determined whether or not the document image data of that type can be set by the setting permission bit (S2). If it can be set, the operation unit 8
From 7, whether the rotation of the document image data is enabled or disabled is set and input as “1” or “0” (S 3), and the input value is written to the user setting bit of the table data T 1.

On the other hand, if the setting is not possible in the determination in S2, a message "cannot be set" is displayed on the display section 86 (S4). Thereafter, it is determined whether the setting has been completed for all types of document image data (S
5). Until the setting of all types is completed, the above S1
The processing operations of S5 to S5 are repeatedly executed, and when the setting of all types is completed, the processing operation ends.

In this setting operation, when the type of the original image data is the normal reception data, the data is rotated according to the size of the reception data, and the cut paper 56 is processed.
Need to be recorded above. Therefore, the table data T
In the 1 user setting bit, rotatable is input and set.

When the type of the document image data is copy data, the copy document 21 may be rotated and placed on the document feeding section 12 or the document placing section 13 as necessary. If the type of the document image data is confidential reception data, the operator who is the confidential recipient who received the data copies the data to the cut sheet 5 by operating the operation unit 87.
Record on 6. Further, when the type of the original image data is polling reception data, the original image data in the apparatus on the called side is requested from the calling side and transmitted. In these cases, if the document image data is rotated, it takes a long time to make the operator wait. For this reason, it is desirable to input and set rotation prohibition in the user setting bit.

When the type of the original image data is printer data, the data is transmitted from the personal computer 92 via the external interface 93 to the CPU 82.
Is input to Then, the printer mode is automatically set in the apparatus main body 11, and recording is performed according to the control of the personal computer 92. Therefore, there is no need to rotate the data on the communication terminal apparatus side. Therefore, the user setting bit is set so that rotation is disabled.

On the other hand, when the type of the original image data is the encrypted data, if the data is rotated, the decryption may be difficult as described above. Therefore, "0" is input to the setting enable / disable bit of the table T1, and the setting is disabled. That is, in this case, the rotation process of the document image data is prohibited.

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

When one page of the document image data is input (S6), it is identified which type the document image data belongs to (S7). Here, when the document image data is related to facsimile communication, in the facsimile transmission control procedure, the detection of a predetermined signal exchanged between the calling side and the called side prior to data transmission causes the document to be scanned. The type of the image data is identified. That is, when the original image data is the normal reception data, the encrypted data, and the confidential reception data, the original image data is identified by the signal following the non-standard function setting signal (NSS) sent from the calling side. When the original image data is polling reception data, it is identified by a digital transmission command signal (DTC) sent from the calling side.

On the other hand, when the document image data is copy data, it is identified by a mode switching operation of the function selection key 87a of the operation unit 87 or the like. When the document image data is data for a printer, the document image data is identified by being input via the external interface 93.

Thereafter, the user setting bit of the table data T1 is searched (S8), and it is determined whether or not the document image data can be rotated (S9). If it is determined that the data cannot be rotated, the document image data is recorded on the cut sheet 56 of a predetermined size without being rotated (normal printing, S10), and the process ends. On the other hand, when it is determined that the data can be rotated, it is determined whether the document image data needs to be rotated based on the size of the document image data and the size of the cut sheet 56 (S11). Is done.

Here, when it is determined that the rotation processing is unnecessary, the original image data is recorded on the cut sheet 56 of a predetermined size without being subjected to the rotation processing (S10), and the processing ends. On the other hand, when it is determined that the rotation process is necessary, the document image data is recorded on the cut sheet 56 of a predetermined size in a state of being rotated by 90 degrees (rotation printing, S
12), the process ends.

The effects that can be expected from the above embodiment will be described below. In the communication terminal device according to this embodiment, it is determined whether or not the document image data is to be rotated by 90 degrees and recorded according to the type of the document image data. For this reason, the rotation process of the document image data can be determined according to the type of the data. Then, for example, by inhibiting the rotation processing of the encrypted data, it is possible to suppress the possibility that decryption becomes difficult as in the above-described conventional configuration. In addition, for example, a long processing time is required for the rotation processing of confidential reception data, polling reception data, and the like, so that it is possible to avoid waiting for the operator.

In the communication terminal device of this embodiment, table data T1 storing whether or not the document image data can be rotated is provided for each type of document image data, and the document image data is rotated based on the table data T1. It is determined whether or not to perform the operation. Therefore, by changing the setting of the information stored in the table data T1, it is possible to easily cope with a change in the specification of the apparatus.

The above embodiment can be embodied with the following modifications. Reading the control program recorded in the recording medium 91 into the RAM 84 via the recording medium reading unit 90 and the CPU 82 to control the operation of the communication terminal device.

The type of the document image data stored in the table data T1 is appropriately increased / decreased or changed. A switching key corresponding to each type of document image data is provided in the operation unit 87 so that even if the document image data is related to facsimile communication, the type of the document image data is determined by operating the switching key. To do.
