Also, the indications of "high image quality", "automatic", "normal", and "confidential communication" in the lower middle row correspond to the "image quality", "read size", "density", and "confidential communication" in the lower row, respectively. Shows the current settings. That is, the image quality is high, the reading size is automatic recognition of the communication terminal device 1, the density is normal density, and the confidential communication is that if the facsimile communication is performed as it is, the confidential communication is performed. Confidential communication is a function of performing communication by designating the other party.

Further, the setting keys 2 are used for the respective displays "image quality", "reading size", "density" and "confidential communication" in the lower row.
It corresponds to 3, 24, 25, 26, and the setting key 23,
The respective settings can be made by operating 24, 25, and 26. For example, if the setting key 23 corresponding to the "image quality" display is operated, the display is changed to the image quality setting screen as shown in FIG.
The setting can be performed by operating 3, 24, 25, and 26. In the present specification, the operation of the setting key in conjunction with the display on the display unit as described above is called a soft key operation, and such a display on the display unit 11 is called a soft key use screen.

Next, the enlarged display of the display unit 11 will be described. The communication terminal device 1 can enlarge the display of the display unit 11 by the user operating the enlargement key 28 of the operation unit 12. This operation will be described step by step with reference to the flowcharts of FIGS. In addition,
The following operation is performed by the control unit 2 controlling each device such as the display unit 11 and the operation unit 12 based on the control program stored in the ROM 3.

Now, it is assumed that the display section 11 is displaying an initial display when a facsimile operation is performed, as shown in FIG. When the user operates the operation unit 12 in this display, the control unit 2 first determines whether the enlargement key 28 has been operated (S).
1). When it is determined that the stop key 29 has been operated, it is determined whether the stop key 29 has been operated (S2). If the stop key 29 has been operated, the process here is terminated. That is, the enlarged display is not performed.

On the other hand, if it is determined in S2 that the stop key 29 is not operated, the process returns to the beginning and is repeated. That is, it waits for the operation of the enlargement key 28. It should be noted that key operations other than the operation of the enlargement key 28 will not be described in detail, but the corresponding operations are performed. For example, the facsimile key communication is performed according to the operation of the start key 30, and the soft key operation for performing various settings according to the operation of the setting keys 23, 24, 25 and 26 is performed.

On the other hand, when it is determined in S1 that the operation is the operation of the enlargement key 28, the previous display, that is, the upper left portion of the display shown in FIG. 3A is enlarged as shown in FIG. 6A. It is displayed on the entire surface of the display unit 11 (S3). Note that, here, the entire original display screen before enlargement, which is the previous display, is divided into a predetermined portion, which is the "T" shape, and the first portion is displayed.

Next, in order to indicate which portion of the display before the enlargement corresponds to the enlarged portion, information 33 indicating the enlarged portion is displayed. Here, the entire display before enlargement is shown in the upper right portion of the display unit 11 in the shape of a "T", and the enlarged portion region, that is, the upper left portion is displayed in dark color to show the enlarged portion to the user. (S4).

From the next step, the operation for a new key operation in the enlarged display as described above will be described. During the enlarged display operation, the control unit 2 determines whether or not any key of the operation unit 12 is operated (S5), and when it is determined that there is no key operation, the key operation is awaited. , S5 is repeated. on the other hand,
If it is determined in S5 that one of the keys has been operated, first, the operated key is the setting key 23, 24, 25, 26.
(S6), and if it is determined to be no, it is then determined whether or not it is the cross cursor key 27 for instructing the up, down, left and right directions (S7). When it is determined that the cursor is the cross cursor key 27, it is further determined whether the display can be moved in any of the up, down, left, and right directions designated by the cross cursor key 27 (S8), and it is determined no. For example, the refusal buzzer warns the user that the instruction is invalid (S9). On the other hand, when it is determined that the user can move, the portion in the designated direction is enlarged and displayed (S
10). When the portion in the direction designated in S10 is enlarged and displayed, information indicating the enlarged portion indicating which portion of the entire enlarged display portion is displayed is displayed (S11) to notify the user.

The operations of S7 to S11 are performed, for example, when the cross-shaped cursor key 2 is operated when the display 11 is displaying the enlarged upper left portion of FIG. 3A as shown in FIG. 6A.
When the left direction and the up direction are specified by 7, these directions become the external directions in the display before the enlargement, and the enlarged part cannot be moved and displayed in these directions, and a warning is given by the rejection buzzer. However, when the right direction is designated by the cross cursor key 27, the enlarged portion is moved to the upper right portion of the entire display, and the upper right display of FIG. 3 (a) is enlarged as shown in FIG. 6 (b). It indicates that the display is performed. Further, when the downward direction is designated by the cross cursor keys, as shown in FIG.
The lower left half of the display will be enlarged. Then, in any of the enlarged displays, the information 33 indicating the enlarged portion in which the enlarged portion of the "square" figure is displayed in dark color is displayed.

On the other hand, in S6, the setting keys 23, 24, 25,
If it is determined that the operation is any one of 26, it is then determined whether the soft key use screen is displayed (S12),
If it is determined to be no, the rejection buzzer notifies the user that the soft key operation cannot be performed. on the other hand,
If it is the soft key use screen, the operation is performed based on the specification of the corresponding soft key (S13). For example, when the display shown in FIGS. 6A and 6B is not the soft key use screen, the setting key 2
When any of 3, 24, 25, 26 is operated,
Warn users with a reject buzzer. In addition, FIG.
When the setting keys 23 to 24 are operated, the input of these setting keys 23 to 24 is permitted, and the display is displayed on the image quality setting screen as shown in FIG. 7B. change. Similarly, when the setting keys 25 to 26 are operated, the input of these setting keys 25 to 26 is permitted, and the display is changed to the reading size setting screen. Thus, if the enlarged portion displays the key reception even during the enlarged display, the key input can be permitted and accepted. That is, soft key operation is possible. Note that FIG. 7B is a diagram in which the left half of FIG. 3B is enlarged and displayed, and in this display, since the display is two lines, the screen is divided into two splits, left and right only. The information 33 indicating the enlarged portion is also divided into two correspondingly. Of course, the display may be divided into four, like the others.

On the other hand, if it is determined NO in S7, it is then determined whether the enlargement key 28 is operated (S14).
When it is determined that the enlargement key 28 has been operated, the display is returned to the original state (S15) and the operation is repeated. That is, the operation is repeated from the enlarged display to the normal display and back to S1.

On the other hand, if it is determined NO in S14, it is then determined whether or not any one of the mode switching keys, that is, the facsimile key 21 and the copy key 22 which are mode switching keys has been operated (S16). When it is determined that any one of the mode switching keys has been operated, it is further determined whether or not mode switching is necessary (S17). This corresponds to the case where the copy mode key 22 is operated when the facsimile function is set, or the case where the facsimile mode key 21 is operated when the copy function is set, and in this case, it is designated. Then, the enlarged display operation is terminated and the operation is transferred to the designated mode. This is to avoid user confusion due to enlarged display when switching modes.

On the other hand, when it is determined to be no in S16 or when it is determined to be no in S17, this means that the mode switching key is operated and the switching to the same mode as the current mode is instructed. , But in these cases,
Next, it is judged whether or not the stop key 29 is operated (S1
9) If it is determined to be no, the process returns to S5 and the operation is repeated. That is, a standby operation is performed due to another key input.

On the other hand, if it is determined in S19 that the stop key 29 has been operated, the enlarged display operation is ended.

On the other hand, when the information indicating the enlarged portion is displayed in S11, and when the warning is given by the reject buzzer in S9,
Alternatively, when the soft key operation corresponding to the operation of the setting key is performed in S13, the process returns to S5 and stands by to accept the operation of another key again.

The enlarged display is not limited to the display during the facsimile function, but can be naturally displayed during the copy function. For example, when the enlargement key 28 is operated in the initial display during the copy function shown in FIG. 8A, the upper left portion of FIG. 8A is displayed on the entire surface of the display unit 11 as shown in FIG. 8B. In addition, the information 33 indicating the enlarged portion is added and displayed. In the above description, the display is "Ta"
It was divided into four parts of the letter shape, and the one part was enlarged and displayed, but two columns vertically and three horizontally.
It may be divided into 6 parts of “2 × 3” in the row and the part 1 may be enlarged and displayed, or may be divided into 9 parts of “3 × 3”, which is suitable for the size of the display unit 11. It is possible to select any number of divisions. In that case, the information 33 indicating the enlarged portion is also changed according to the number of divisions.
