[0002]

2. Description of the Related Art During operation of a device having display means such as a cathode ray tube or a liquid crystal display device, it is not possible for an operator to temporarily leave the device, perform other tasks such as meetings, or receive a telephone call. Can happen frequently on a daily basis. Even in such a case, the operator rarely turns off the power of the apparatus each time. In particular, when the apparatus is operated in a state where the operation mode is shifted from the main menu to a certain operation mode, the operation is often interrupted while the apparatus is in the ON state. In this case, in order to prevent burn-in of the display screen and to reduce power consumption, the display is stopped in a state where the display data is held, and the display data held when the operator resumes the operation. There is known an apparatus having a so-called screen save function for restoring the display screen immediately before the display is stopped in response to the above.

[0003]

However, in the conventional screen save function, when the display screen immediately before the stop of the display is restored in response to the restart of the operation, the operator forgets the operation mode immediately before the stop of the display. If this happens, there is a problem that work cannot be resumed even if the restored display screen is viewed. In particular, when the interrupted work is processing of a data file or the like, the created data may be lost. SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for promptly resuming a work even if the display mode is restored by the screen save function and the operation mode immediately before the display stop is forgotten.

Next, regarding the operation of the configuration of the embodiment, C
This will be described with reference to the flowchart of the PU 1 and the screen displayed on the display unit 7. In the main flow of the CPU 1 shown in FIGS. 8 and 9, an initialization process is performed (step A1), and as shown in FIG. 10, "transmission / reception", "address book", "new mail", "mail box", "FA"
A menu selection screen displaying icons of "X" and "Setting" is displayed (step A2). Further, the display mode of the “transmit / receive” icon is changed on this screen (step A).
3). As the change of the display mode, for example, reverse display or highlighted display is performed.

Next, it is determined whether or not the cursor switch has been turned on (step A4). When it is turned on, the display mode of another icon different from the icon whose display mode is currently changed is changed (step A5). Next, R
It is determined whether the ETURN switch has been turned on (step A6). If it is not turned on, the process proceeds to step A4 to determine the state of the cursor switch. RETU
When the RN switch is turned on, a processing mode corresponding to the icon whose display mode is changed at that time is executed.

That is, it is determined whether or not the changed display mode is the “transmit / receive” icon (step A).
7) If the display mode of the icon has been changed, a transmission / reception process is executed (step A8). It is determined whether or not the display mode has been changed is the "address book" icon (step A9). If the display mode of this icon has been changed, the address book processing is executed (step A10). ). It is determined whether the display mode has been changed is the "new mail" icon (step A11). If the display mode of this icon has been changed, a new mail process is executed (step A1).
2).

[0020] The display mode is changed in "Mail B
OX "icon (step A1).
3) If the display mode of the icon has been changed, a mail BOX process is executed (step A14).
It is determined whether or not the display mode has been changed is the "FAX" icon (step A15). If the display mode of this icon has been changed, the FAX process is executed (step A16). It is determined whether or not the display mode has been changed is the “setting” icon (step A).
17) If the display mode of the icon has been changed, a setting process is executed (step A18).

In step A6, if the RETURN switch is not turned on, or after the RETURN switch is turned on and a process corresponding to the icon being changed at that time is executed, the process proceeds to step A4, where the cursor switch is turned on. Determine ON / OFF.

FIG. 11 shows the flow of the transmission / reception processing in step A8 of the main flow. In this process, a mail reception process (Step B1), a mail transmission process (Step B2), and a FAX transmission process (Step B3) are executed.

FIG. 12 shows the flow of the mail receiving process in step B1. First, it is determined whether or not there is a new mail (step B4). If there is no new mail, this flow is immediately terminated. If there is a new mail, 1 is set to the pointer n (step B5), and n
While searching for a free space in the reception area shown in FIG. That is, it is determined whether or not ZYUSIN (n) is empty (step B6), and if not, n is incremented (step B7). And
It is determined whether or not n has exceeded the maximum number (step B
8).

If n is equal to or less than the maximum number, the process shifts to step B6 to determine whether or not ZYUSIN (n) designated by n is empty. Then, n is incremented until there is a free area, and the free ZYUSIN
If (n) is found, the SUBJECT, TO, and body data of the new mail received are written in the area (step B9). Further, the unread flag of ZYUSIN (n) is set to 1 (step B10). Then, the process shifts to step B4 to determine whether or not there is another new mail. If there is no new mail, this flow ends. If n exceeds the maximum number in step B8, new mail data cannot be written, so a warning is displayed for a certain period of time (step B11), and this flow ends.

FIG. 13 shows a flow of the mail transmission process in step B2 of FIG. First, the pointer n is set to 1 (step B12), and the following loop processing is executed while incrementing n. It is determined whether or not the FAX flag of SOSIN (n) in the transmission list shown in FIG. 6 is 0, that is, whether or not SOSIN (n) is not FAX data but mail data (step B1).
3). If the FAX flag is 1, n is incremented (step B14), and the next data SOSIN
It is determined whether (n) is free or whether n exceeds the maximum number (step B15). And SOSIN
If (n) is not empty and n does not exceed the maximum number, the process shifts to step B13 and the SOSIN
The FAX flag of (n) is determined.

In step B13, the FAX flag is set to 0.
If it is (mail), it is determined whether or not the unsent flag of SOSIN (n) is 1 (unsent) (step B16). If this flag is 0, that is, if it has already been transmitted, n is incremented in step B14 to specify the next data SOSIN (n), and the processing in steps B15, B13, and B16 is performed.

In step B16, SOSIN
If the unsent flag of (n) is 1, the contents of the SUBJECT (title) and To (destination) of the data of the screen during mail transmission are written (step B17), and the screen during mail transmission shown in FIG. It is displayed over the menu selection screen (step B18). Next, a mail transmission process is executed (step B19). Then, it is determined whether or not the transmission has been completed (step B20). If the transmission has not been completed, the process proceeds to step B19 to continue the transmission. When the transmission is completed, the untransmitted flag of SOSIN (n) is reset to 0 (step B21),
Write the transmission time to SIN (n) (step B2
2). Then, the screen during mail transmission is deleted (step B23).

Thereafter, in step B14, n is incremented to specify the next data SOSIN (n). Then, in step B15, SOSIN
When (n) is not empty and n does not exceed the maximum number, an unsent mail is transmitted while incrementing n. In step B15, SOSIN
If (n) is empty or n exceeds the maximum number, this flow is terminated.

FIG. 15 shows the flow of the FAX transmission process in step B3 of FIG. First, the pointer n is set to 1 (step B24), and the following loop processing is executed while incrementing n. It is determined whether or not the FAX flag of SOSIN (n) in the transmission list shown in FIG. 6 is 1, that is, whether or not SOSIN (n) is FAX data (step B25). FAX flag is 0
If it is (mail), n is incremented (step B26), and it is determined whether the next data SOSIN (n) is empty or n exceeds the maximum number (step B27). SOSIN (n) is not empty,
If n does not exceed the maximum number, step B
The process proceeds to S25, and the FAX flag of the SOSIN (n) is determined.

In step B25, the FAX flag is set to 1
If it is (FAX), it is determined whether the unsent flag of SOSIN (n) is 1 (unsent) (step B28). If this flag is 0, that is, if it has already been transmitted, n is incremented in step B26 to specify the next data SOSIN (n), and the processing in steps B27, B25, and B28 is performed.

In step B28, SOSIN
If the untransmitted flag in (n) is 1, the content of the FAX number on the FAX transmitting screen is written (step B2).
9) The FAX transmission screen shown in FIG. 16 is displayed over the menu selection screen (step B30). Next, F
An AX transmission process is executed (step B31). And
It is determined whether the transmission has been completed (step B32).
If the transmission has not been completed, the process shifts to step B31 to continue the transmission. When transmission is completed, SOS
The non-transmission flag of IN (n) is reset to 0 (step B33), and the transmission time is written to SOSIN (n) (step B34). Then, the FAX transmitting screen is deleted (step B35).

Thereafter, in step B26, n is incremented to specify the next data SOSIN (n). Then, in step B27, SOSIN
If (n) is not empty and n does not exceed the maximum number, the untransmitted FA is incremented while n is incremented.
Send X data. In step B27, the SOS
If IN (n) is empty or n exceeds the maximum number, this flow is terminated.

Step A1 in the main flow of FIG.
FIGS. 17 to 22 show the flow of the address book process of No. 0.
In this process, the display of the menu selection screen is cleared (step C1), and the address book list frame screen shown in FIG. 23 is displayed (step C2). And the pointer n
Is set to 1 (step C3), and address data designated by n is displayed while incrementing n. That is, it is determined whether or not ADD (n) is not empty (step C4). If not, the name, address and telephone number of ADD (n) are displayed (step C5).
Further, it is determined whether or not there is a fax number in ADD (n) (step C6), and if so, a fax mark “F” is displayed (step C7).

Next, n is incremented (step C8), and the next ADD (n) is designated. Then, it is determined whether or not n exceeds the maximum number (step C9). If n is equal to or less than the maximum number, the process shifts to step C4 to determine whether or not the specified ADD (n) is empty. If n exceeds the maximum number in step C9, or
In the case where ADD (n) is empty in FIG.
In step C10, it is determined whether n is not 1. If n is not 1 and there is at least one address data, the pointer m is set to 1 (step C11). Then, the display mode of ADD (m = 1) is changed (step C12).

Next, it is determined whether or not the up cursor switch or the down cursor switch has been turned on (step C1).
3). If any of the cursor switches is turned on, it is determined whether or not it is an up cursor switch (step C14). If it is not the up cursor switch but the down cursor switch, it is determined whether or not m is not n-1 (step C15). That is, it is determined whether the address whose display mode is changed is not the lowest address. If m is not n-1 and is not the lowest address, m is incremented (step C1).
6) Specify the next lower address. Then, the flow shifts to step C12, where the designated address ADD (m)
Is changed.

In step C14, if the turned-on cursor switch is an up cursor switch, m
Is determined whether is not 1 (step C17). That is, it is determined whether the address whose display mode is changed is not the top address (step C17). m
If is not 1 and is not the top address, m is decremented (step C18), and the next higher address is designated. Then, the process shifts to step C12 to change the display mode of the specified address ADD (m).

If m is n-1 in step C15, that is, if the address whose display mode is changed is the lowest address, the operation of the down cursor switch becomes invalid. In this case, the process proceeds to step C12, but ADD (m) whose display mode has been changed is the same as before the down cursor switch operation. Similarly, if m is 1 in step C17, that is, if the address whose display mode is changed is the top address, the operation of the up cursor switch is invalidated. In this case as well, the process proceeds to step C12, but ADD (m) whose display mode has been changed is the same as before the up cursor switch operation.

In step C13, if neither the upper cursor switch nor the lower cursor switch is turned on, it is determined whether or not the ESC switch is turned on (step C19). If it is turned on, the display of the address book list screen is cleared (step C20), and this flow ends. In Step C10,
If n is 1, that is, if there is no address list, it is determined whether or not the ESC switch has been turned on (step C21). If it has been turned on, the display of the address book list screen is cleared. This flow ends.

If the ESC switch is not turned on in step C19, it is determined in step C23 in FIG. 19 whether the MENU switch has been turned on. When turned on, the menu screen (A-
A) is displayed over the address book list screen (step C24). And this menu screen (AA)
The display mode of the "mail" icon among the three icons is changed (step C25).

Next, it is determined whether or not the left cursor switch or the right cursor switch has been turned on (step C2).
6). If any of the cursor switches is turned on, the display mode of another icon different from the icon whose display mode is currently changed is changed (step C27).
Next, it is determined whether or not the RETURN switch has been turned on (step C28). If not turned on, ES
It is determined whether or not the C switch is turned on (step C
29). If this switch is not turned on, the process goes to step C26 to determine whether the cursor switch is turned on. When the ESC switch is turned on, the menu screen (AA) of FIG. 24 is deleted (step C30),
The process proceeds to step C23 to determine whether the MENU switch is on.

When the RETURN switch is turned on in step C28, it is determined whether or not the display mode of the "mail" icon has been changed (step C3).
1). If the display mode of this icon has been changed, a new mail process is executed (step C32). After the end of the new mail process, the process shifts to step C2 in FIG. 17 to display the address book list screen again. The new mail processing is performed in step A in the main flow of FIG.
Twelve new mail processes, which will be described later.

If the icon whose display mode has been changed is not "mail" at step C31 in FIG. 19, it is determined whether the display mode of the "name" icon has been changed (step C33). If the display mode of the icon has been changed, the menu screen (AB) of FIG. 24 is displayed together with the menu screen (AA) (step C34). Then, this menu screen (A-
The display mode of the "new" icon of the two icons B) is changed (step C35).

Next, the flow shifts to step C36 in FIG. 20, to determine whether or not the left cursor switch or the right cursor switch has been turned on. When one of the cursor switches is turned on, the display mode of another icon different from the icon whose display mode is currently changed is changed (step C37). Then, it is determined whether or not the RETURN switch has been turned on (step C38). If this switch is not turned on, it is determined whether or not the ESC switch has been turned on (step C39). If this switch is not turned on, the process proceeds to step C2 in FIG.
Then, the process goes to 6 to determine whether the cursor switch is turned on.

If the RETURN switch is turned on in step C38, it is determined whether the display mode of the "new" icon has been changed (step C4).
1). If the display mode of the icon has been changed, an address registration process is executed (step C42).
If it is determined in step C41 that the display mode has not been changed to the “new” icon, the display mode of the “delete” icon has been changed, and the deletion process is executed (step C43). After the end of the address registration process or the deletion process, the process shifts to step C2 in FIG. 17 to display the address book list frame screen again.

In step C23 of FIG.
If the U switch is not turned on, the process shifts to step C44 in FIG. 21 to determine whether the RETURN switch is turned on. If it is turned on, the display is cleared (step C45), and the address input frame screen shown in FIG. 25 is displayed (step C46). Then, the content of ADD (m) whose display mode has been changed is displayed in the frame (step C47). Then, a cursor is displayed on the nickname frame on this screen (step C48).

Next, it is determined whether or not there is a data input (step C49). If there is data input, it is determined whether or not the cursor is in the input frame (step C5).
0) If it is in the input box, the data input in the input box where the cursor is located is displayed (step C51). Then, the process shifts to step C49 to determine whether or not there is any further data input. If there is no data input, or if the cursor is not in the input frame in step C50, it is determined whether or not the cursor switch has been turned on (step C52). If the cursor switch has been turned on, the cursor is moved (step C53). ). Then, the process shifts to step C49 to determine whether there is a data input.

If it is determined in step C52 that the cursor switch has not been turned on, it is determined whether the RETURN switch has been turned on (step C54). If it is not turned on, the process shifts to step C49 to determine whether there is data input. If the RETURN switch has been turned on, it is determined whether the cursor is on the "cancel" icon (step C55). If the cursor is on this icon, the display is cleared (step C56), and the routine goes to step C2 in FIG. 17, where the address book list frame screen is displayed again.

If the cursor is not on the "cancel" icon in step C55 of FIG. 21, it is determined whether the cursor is on the "input" icon (step C57). If the cursor is not over this icon, the process moves to step C49 to determine data input. If the cursor is on this icon, an address setting process is executed (step C58). Thereafter, the process proceeds to step C56 to clear the display, and then proceeds to step C2 in FIG. 17 to display the address book list frame screen again.

In the menu screen shown in FIG. 24, the display mode is changed in step C31 of FIG.
If the icon is not the “mail” icon and the name is not “name” in step C33, the display mode has been changed to the “special” icon. The displayed menu screen (AC) is displayed together with the menu screen (AA).
Then, the display mode of the “search” icon of the two icons on this screen is changed (step C60).

Next, it is determined whether or not the left cursor switch or the right cursor switch has been turned on (step C6).
1). If either of the cursor switches is turned on, the display mode of another icon different from the icon whose display mode is currently changed is changed (step C62).
Then, it is determined whether or not the RETURN switch has been turned on (step C63). If this switch is not turned on, it is determined whether or not the ESC switch has been turned on (step C64). If this switch is not turned on, the process proceeds to step C26 in FIG. 19 to determine whether the cursor switch is turned on. When the ESC switch is turned on, the menu screen (AC) is deleted (step C65), and the process proceeds to step C26 in FIG.
Determine whether the cursor is on.

If the return switch is turned on in step C63, it is determined whether or not the display mode of the "search" icon has been changed (step C6).
6). If the display mode of this icon has been changed, a search process is executed (step C67). If it is determined in step C66 that the display mode has not been changed to the "search" icon, the display mode of the "sort" icon has been changed, so that the sorting process is executed (step C68). After the end of the search processing or the sort processing, the process shifts to step C2 in FIG. 17 to display the address book list frame screen again.

FIGS. 26 to 31 show the flow of the new mail process in step A12 in FIG. 9 and step C32 in FIG. In this process, the display is cleared (step D1), and the header input screen shown in FIG. 32 is displayed (step D2). Then, move the character cursor to SUBJ on the screen.
It is displayed in the ECT input area (step D3). next,
It is determined whether or not the cursor switch has been operated to move the cursor (step D4). If the cursor has been moved, the character cursor is moved to another input area (step D5).

If the cursor is not moved in step D4, it is determined whether or not there is data input (step D6). If there is data input, a data input process is executed (step D7). In this data input processing, as shown in FIG. 27, data is input to an input area where a character cursor is located (step D7-1), and RETUR is input.
It is determined whether the N switch has been turned on (step D).
7-2). If it is turned on, it is determined whether or not the character cursor position is in the "To" area (step D).
7-3). If it is this area, an address setting process is executed to perform a process of automatically displaying the domain name (step D7-4). In step D7-2, RE
If the TURN switch is not turned on, or step D
If the character cursor is not in the area of "To" in 7-3, the flow of the data input processing is terminated without performing the address setting processing.

After inputting the data, the process shifts to step D4 to determine the movement of the cursor. If there is no data input in step D6, it is determined whether or not the MENU switch has been turned on (step D8). If it is not turned on, the process goes to step D4 to determine the cursor movement. When the MENU switch is turned on, the mail creation menu screen shown in FIG. 33 is displayed over the header input screen (step D9). Then, the display mode of the "text" icon is changed (step D10). After the character cursor is moved in step D5, after the data is displayed in step D7, or when the MENU switch is not turned on in step D8, the process proceeds to step D4 to determine the cursor movement.

After the display mode is changed in step D10, FIG.
The process shifts to step D11 of step 8 to determine whether or not the ESC switch is turned on. When turned on, FIG.
Delete the mail creation menu screen (step D1)
2) Then, the process proceeds to step D4 in FIG. 26 to determine the cursor movement. If the ESC switch is not turned on in step D11, it is determined whether or not the cursor switch is turned on (step D13). If it is turned on, the icon for changing the display mode is switched (step D14). Then, the process goes to step D11 to
Determine whether the switch is on.

If the cursor switch is not turned on in step D13, it is determined whether or not the RETURN switch is turned on (step D15). If it is not turned on, the process proceeds to step D11, where it is determined whether the ESC switch is on. When the RETURN switch is turned on, it is determined whether or not the display mode of the “text” icon has been changed (step D16). If the display mode of this icon has been changed, the display of the header input screen and the mail creation menu screen is deleted (step D17A), and the text input screen shown in FIG. 34 is displayed (step D17B). Then, a character cursor is displayed at a predetermined position (step D18).

Next, it is determined whether or not there is a data input (step D19). If there is a data input, the input data is displayed at the character cursor position (step D2).
0). Next, it is determined whether or not the MENU switch has been turned on (step D21). If it is not turned on, the process proceeds to step D19 to determine whether there is data input. When the MENU switch is turned on, FIG.
The process proceeds to step D9 to display a mail creation menu screen.

If it is determined in step D16 in FIG. 28 that the display mode has not been changed to the "body" icon, it is determined whether the display mode of the "header edit" icon has been changed (step D22). . If the display mode of the icon has been changed, the process proceeds to step D1 in FIG. 26, where the display of the mail creation menu screen is cleared, and the header input screen is displayed in step D2.
If it is determined in step D22 that the display mode has not been changed to “edit header”, the process proceeds to step D22 in FIG.
The process proceeds to 23 to determine whether or not the display mode of the “send” icon has been changed. If the display mode of this icon has been changed, a mail transmission menu screen shown in FIG. 35 is displayed (step D24). Then, the display mode of the "send immediately" icon on this screen is changed (step D25).

Next, it is determined whether or not the cursor switch has been turned on (step D26).
Switch the icon for changing the display mode (step D
27). Thereafter, the process returns to step D26 to determine whether the cursor switch is turned on. If the cursor switch has not been turned on, it is determined whether or not the ESC switch has been turned on (step D28). If turned on,
Delete the mail transmission menu screen (step D2)
9). Then, the flow shifts to step D9 in FIG. 26, to display a mail creation menu screen.

If the ESC switch is not turned on in step D28 of FIG. 29, it is determined whether or not the RETURN switch is turned on (step D30). If it is turned on, it is determined whether or not the display mode of the "immediate transmission" icon has been changed (step D3).
1). If the display mode of this icon has been changed, a mail direct transmission process is executed (step D3).
2). Then, the display is cleared (step D33),
This flow ends. In step D23, if the display mode is not the “send” icon, that is, if the display mode of the “cancel” icon is changed, the display is cleared (step D3).
4), end this flow.

If it is determined in step D31 that the display mode has not been changed to the "send immediately" icon, the flow shifts to step D35 in FIG. 30 to determine whether the display mode of the "send on access" icon has been changed. It is determined whether or not. If the display mode of the icon has been changed, the pointer n is set to 1 (step D3).
6) While searching for an empty area of the transmission book shown in FIG. 6 while incrementing n. That is, it is determined whether or not the SOSIN (n) area is empty (step D3).
7). If not empty, n is incremented (step D38), and it is determined whether or not n exceeds the maximum number (step D39). If n is equal to or less than the maximum number, the process shifts to step D37 to determine whether or not the SOSIN (n) area is empty.

In step D37, SOSIN (n)
If the area is empty, the data of From, To, SUBJECT and the text of the created mail are written in the area (step D40). FAX
The flag is reset to 0, and the untransmitted flag is set to 1 (step D41). Then, the display is cleared (step D42), and this flow ends. Step D3
If n exceeds the maximum number in step 9, since there is no empty area, a warning is displayed for a certain period of time (step D43), and the flow shifts to step D26 in FIG. 29 to determine whether the cursor switch is on. I do.

In step D35 of FIG. 30, if the display mode is not the “send on access” icon, the display mode of the “save end” icon has been changed. And the pointer n is set to 1. Then, while n is incremented, an empty area of the editing book shown in FIG. 5 is searched. That is, it is determined whether or not the HENSYU (n) area is empty (step D45). If not empty, n is incremented (step D46),
It is determined whether or not n has exceeded the maximum number (step D4)
7). If n is equal to or less than the maximum number, step D45
Then, it is determined whether or not the area of HENSYU (n) is empty.

In step D45, HENSYU
If the area (n) is vacant, the From, To, SUBJECT, and body data of the created mail are written in the area (step D48). Also,
The FAX flag is reset to 0, and the save flag is set to 1 (step D49). Then, the display is cleared (step D50), and this flow ends. If n exceeds the maximum number in step D47, there is no empty area, so a warning is displayed for a certain period of time (step D51), and the process proceeds to step D26 in FIG.
Determine whether the cursor switch is on.

Step A1 in the main flow of FIG.
FIG. 36 shows a flow of the mail BOX processing of No. 4. In this process, the display of the menu selection screen shown in FIG. 10 is cleared (step E1), and the mail box icon screen shown in FIG. 37 is displayed (step E2). Then, the display mode of the "receiver" icon on this screen is changed (step E3). Next, it is determined whether or not the cursor switch has been turned on (step E4). When the cursor switch has been turned on, the display mode of another icon different from the "receiver" icon whose display mode is currently changed is changed. (Step E5).
Then, the process shifts to step E4 to determine whether the cursor switch is turned on.

If the cursor switch is not turned on, it is determined whether the return switch is turned on (step E6). If it is turned on, it is determined whether or not the display mode of the “receiver” icon has been changed (step E7). If the display mode of this icon has been changed, a reception list process is executed (step E).
8). If the display mode has not been changed to the "receiver book" icon, it is determined whether the display mode of the "edit book" icon has been changed (step E9). If the display mode of this icon has been changed, an edit book process is executed (step E10). If the display mode is not the “edit book” icon, it is determined whether the display mode of the “transmission book” icon is changed (step E11). If the display mode of the icon has been changed, a transmission list process is executed (step E12). After executing each process, the process shifts to step E4 to determine whether the cursor switch is turned on.

If the return switch is not turned on in step E6, it is determined whether or not the ESC switch is turned on (step E13). If the cursor switch is not turned on, the process proceeds to step E4 to determine whether the cursor switch is turned on. If the ESC switch is turned on, the display is cleared (step E14), and this flow ends.

Step A1 in the main flow of FIG.
38 to 41 show the flow of the FAX processing of No. 6. In this process, first, the display of the menu selection screen shown in FIG. 10 is cleared (step F1), and the FAX shown in FIG.
A screen is displayed (step F2). Then, the character cursor is displayed at the upper left position (step F3). Next, it is determined whether or not the cursor switch has been turned on (step F4). If the cursor switch has been turned on, the character cursor is moved (step F5).

Next, it is determined whether or not there is a data input (step F6). If there is a data input, the input data is displayed at the character cursor position (step F6).
7). Then, the character cursor is moved in preparation for the next data input (step F8), and the process proceeds to step F4 to determine whether the cursor switch is turned on. If there is no data input in step F6, it is determined whether or not the ESC switch has been turned on (step F9). If it is turned on, the display is cleared (step F10), and this flow ends.

If it is determined in step F9 that the ESC switch has not been turned on, the flow shifts to step F11 in FIG. 39 to determine whether the MENU switch has been turned on. When turned on, the menu screen (F-
A) is displayed over the FAX screen of FIG. 42 (step F12). Then, the display mode of the “FAX transmission” icon among the three icons on this screen is changed (step F13).

Next, it is determined whether or not the cursor switch has been turned on (step F14). Change the mode (step F
15). Next, it is determined whether or not the RETURN switch has been turned on (step F16).
It is determined whether or not the display mode of the “AX transmission” icon has been changed (step F17). If the display mode of the icon has been changed, a facsimile transmission preparation process is executed (step F18). After this processing, the flow shifts to step F1 in FIG. 38 to clear the display.

If it is determined in step F17 in FIG. 39 that the changed display mode is not the "FAX transmission" icon, it is determined whether the display mode of the "FAX" icon has been changed (step F19). . If the display mode of the icon has been changed, the menu screen (FB) shown in FIG. 43 is displayed below the menu screen (FA) (step F20). Then, the display mode of the "new" icon on the menu screen (FB) is changed (step F21). In step F19, if the display mode is not the “new” icon, the menu screen (FC) shown in FIG. 43 is displayed together with the menu screen (FA) (step F22). Then, the display mode of the "search" icon on this menu screen (FC) is changed (step F23).

If it is determined in step F16 that the RETURN switch has not been turned on, it is determined whether the ESC switch has been turned on (step F24). If the cursor switch is not turned on, the process proceeds to step F14 to determine whether the cursor switch is turned on. If the ESC switch is turned on, the menu screen (FA) is erased (step F25). Then, the flow shifts to step F4 in FIG. 38, to determine whether the cursor switch is on.

After the display mode of the "new" icon on the menu screen (FB) is changed in step F21 in FIG. 39, the flow shifts to step F26 in FIG. 40, and the left cursor switch or the right cursor switch is turned on. It is determined whether or not it has been performed. If it is turned on, the display mode of another icon designated by operating the cursor switch is changed (step F27).

Next, it is determined whether or not the RETURN switch has been turned on (step F28). If it is turned on, it is determined whether or not the display mode of the "new" icon has been changed (step F29). If the display mode of the “new” icon has been changed, the process proceeds to step F1 in FIG. 38 to clear the display. If the display mode of this icon has not been changed, it is determined whether or not the display mode of the “delete” icon has been changed (step F30). If the display mode of the icon has been changed, a deletion process for deleting FAX data is executed (step F31). Then, the flow shifts to step F1 in FIG. 38 to clear the display.

If it is determined in step F30 that the display mode of the "delete" icon has not been changed, it is determined whether the display mode of the "move" icon has been changed (step F32). If the display mode of the icon has been changed, a moving process for moving the FAX data to another area is executed (step F33). Then, the flow shifts to step F1 in FIG. 38 to clear the display. If the display mode of this icon has not been changed, “S
Since the display mode of the “ave” icon has been changed,
A save process for saving AX data is executed (step F34). Then, the flow shifts to step F1 in FIG. 38 to clear the display.

In step F28 of FIG. 40, RET
If the URN switch is not turned on, it is determined whether or not the ESC switch is turned on (step F35).
If it is turned on, the menu screen (FB) is deleted (step F36). Then, step F1 in FIG.
The process proceeds to step 4 to determine whether the cursor switch is on.

After the display mode of the "search" icon is changed in step F23 in FIG. 39, the flow shifts to step F37 in FIG. 41 to determine whether the left cursor switch or the right cursor switch is turned on. If any of the cursor switches is turned on, the display mode of another icon specified by operating the cursor switch is changed (step F38).

Next, it is determined whether or not the RETURN switch has been turned on (step F39). If it is turned on, it is determined whether or not the display mode of the "search" icon has been changed (step F40). If the display mode of the icon has been changed, a search process is executed (step F41). Then, the flow shifts to step F1 in FIG. 38 to clear the display. If the display mode of this icon has not been changed, the display mode of the “sort” icon has been changed, and the sort process is executed (step F42). Then, the flow shifts to step F1 in FIG. 38 to clear the display.

In step F39 of FIG. 41, RET
If the URN switch is not turned on, it is determined whether or not the ESC switch is turned on (step F43).
If it is turned on, the menu screen (FC) is deleted (step F44). Then, step F1 in FIG.
The process proceeds to step 4 to determine whether the cursor switch is on.

FIGS. 44 and 45 are flow charts of the setting process in step A18 in the main flow of FIG. In this process, first, the display of the menu selection screen shown in FIG. 10 is cleared (step G1), and the mail setting frame screen shown in FIG. 46 is displayed (step G2). Next, the determined setting data is displayed in the input frame (step G).
3) Change the display mode of the "setting" icon (step G4). Further, a character cursor is displayed in a predetermined frame in which the setting data has not been determined (step G5).

Next, it is determined whether or not the ESC switch has been turned on (step G6). If it is turned on, the display is cleared (step G7), and this flow ends. If the ESC switch is not turned on, it is determined whether the up cursor switch or the down cursor switch has been turned on (step G8). If it is turned on, the character cursor is moved to another area (step G9).
If neither the up cursor switch nor the down cursor switch is turned on, it is determined whether the left cursor switch or the right cursor switch has been turned on (step G10). If it is turned on, the display mode of an icon different from the icon whose display mode is currently changed is changed (step G11).

If none of the cursor switches is turned on in steps G8 and G10, it is determined whether or not there is data input in FIG. 45 (step G12). If there is data input, the input data is displayed in the input area where the character cursor is located (step G13). Then, the flow shifts to step G6 in FIG. 44, to determine whether the ESC switch is on. If there is no data input, it is determined whether the RETURN switch has been turned on (step G14). If the switch is not turned on, the flow shifts to step G6 in FIG. 44 to determine whether the ESC switch is on. When the RETURN switch is turned on, it is determined whether or not the display mode of the “setting” icon has been changed (step G15).

If the display mode of the icon has been changed, the input data is stored (step G1).
6). Then, it is determined whether or not the input data has an address (step G17). If you have an address,
The addresses below the $ mark are detected and stored as domain names (step G18). After storing the domain name, or when the display mode of the "cancel" icon is changed without changing the display mode of the "setting" icon in step G15, or in step G1.
If there is no address in the input data in step 7, the display is cleared (step G19), and this flow ends.

FIGS. 47 to 53 show the flow of the reception list processing in step E8 in the mail BOX processing of FIG.
In this processing, first, the display of the mail box icon screen shown in FIG. 37 is cleared (step H1), and the frame screen of the reception list shown in FIG. 54 is displayed (step H).
2). Then, the pointer n is set to 1 (step H3), and the data in the reception list is searched while incrementing n.

ECT data is written (step H5), and ZYUS
It is determined whether or not the unread flag of IN (n) is 1 (step H6). If this flag is 1, an unread mark "*" is displayed (step H7). Then, n
Is incremented (step H8), and it is determined whether or not n exceeds the maximum number (step H9). If n is equal to or less than the maximum number, the flow shifts to step H4, where ZYU
It is determined whether SIN (n) is not empty.

When n exceeds the maximum number in step H9, or in step H4, ZYUSIN (n)
When the following areas are empty, in FIG.
The pointer m is set to 1 (step H10). Next, it is determined whether or not the up cursor switch or the down cursor switch has been turned on (step H12). If the up cursor switch has been turned on, it is determined whether or not m is not 1 (step H13). That is, it is determined whether or not ADD (m) whose display mode has been changed is not at the top. If m is not 1, m is decremented (step H14), and the next higher ZYUSIN (m) is designated. Then, the process shifts to step H11 to change the display mode of the designated ZYUSIN (m).

In step H12, if the turned-on cursor switch is a down cursor switch, m
Is not n-1 (step H15).
That is, the ZYUSIN whose display mode has been changed
It is determined whether (m) is not the bottom. If m is not n-1, m is incremented (step H1).
6) Specify the next lower ZYUSIN (m). Then, the process proceeds to step H11 where the designated ZYUSIN
The display mode of (m) is changed. When m is 1 in step H13, or when m is n-1 in step H15, the process proceeds to step H11.
In this case, the cursor operation is invalidated, and ZYUSIN (n) whose display mode has been changed is the same as before the cursor switch operation.

If neither the upper cursor switch nor the lower cursor switch is turned on in step H12, it is determined whether or not the ESC switch is turned on (step H17). If it is turned on, the display is cleared (step H18), and this flow ends.

If NOPF is 1 in step I1, that is, if the display is off in the screen save state, it is determined in FIG. 81 whether or not the operation element has been operated (step I10). If the operation has been performed, the display is turned on because the use of the device has been resumed (step I11). Then, an explanation screen corresponding to the mode set in the MR is displayed (step I12). That is, the mode name immediately before the display is turned off in the screen save state is displayed. In this case, the mode name may be displayed not only by letters but also by illustrations, or letters and illustrations may be displayed simultaneously. After displaying the mode name, the timer T2 is reset to 0 (step I13). Then, MF is set to 1 (step I14), and NOPF is reset to 0 (step I). Then, the timer interrupt process ends, and the process returns to the main flow.

If the MF is 1 in step I2 in FIG. 80, it is determined in FIG. 82 whether or not the operation element has been operated (step I16). If an operation has been performed, it is determined that the operator has understood the displayed explanation screen and has restarted the operation. Therefore, the explanation screen is erased (step I17), and T1 is reset to 0 (step I18). Further, the MF is reset to 0 (step I19). Then, the timer interrupt process ends, and the process returns to the main flow.

In step I16, if there is no operation of the operator, T2 is incremented (step I16).
20). Then, it is determined whether or not T2 has reached a predetermined value (step I21). When the predetermined value is reached, the operator assumes that the displayed explanation screen cannot be understood and erases the explanation screen (step I22), and resets T1 to 0 (step I23). Further, the MF is reset to 0 (step I24). Then, the timer interrupt process ends, and the process returns to the main flow.

As described above, according to the above embodiment, the key operator 10 constitutes an input means for inputting information in accordance with an operation. The CPU 1 configures a mode setting means for setting an operation mode in accordance with information input from the key operator 10 by a display control program stored in the ROM 3 and sets a predetermined time during which the key operator 10 is not operated. If it exceeds, stop the display on the display,
If the key operator 10 is operated while the display is stopped,
Display control means for restoring the display corresponding to the operation mode set when the display was stopped, and mode display instructing means for displaying an image specifying the operation mode when the display of the operation mode is restored. .

The display is stopped when the duration of time during which the input means is not operated exceeds a predetermined time, and when the input means is operated while the display is stopped, the display corresponding to the operation mode set when the display was stopped. And an image specifying the operation mode is displayed. Therefore, when the display screen is restored by the screen save function, the operation can be promptly resumed even if the operation mode immediately before the display stop is forgotten.

In this case, when the key operator 10 is operated in a state where an image indicating the operation mode is displayed, the operator deletes the image because the operator has recognized the specified operation mode. . Therefore, work efficiency can be improved. Further, when a certain time has elapsed after displaying the image clearly indicating the operation mode, the image is deleted. If the operation is not performed even if the operation mode is specified for a certain period of time, the operator cannot remember the operation mode immediately before the display is stopped. Measures can be taken.

In the text input screen shown in FIG. 34 in the new mail creation processing and the mail editing screen shown in FIG. 64 in the editing book processing, the ruled line at the boundary between the header part and the text is displayed as a solid line. Indicates that input or change is possible. On the other hand, in the reception screen shown in FIG. 55 in the reception list processing, the ruled line at the boundary between the header part and the text is displayed as a dotted line, and it is not possible to input or change data, but only to browse. Is shown.

In this case, the type of the mail may be represented by a character font instead of the type of the mail by the ruled line display mode. For example, an editable mail may be displayed in a Mincho font, and an email that can only be viewed may be displayed in a Gothic font.

That is, display means for displaying the mail,
Display control means for displaying the mail in a different manner depending on whether the mail displayed on the display means can be edited or cannot be edited by browsing alone can easily change the type of the displayed mail. Can be recognized.
In this case, instead of adding special image data and font data for different display modes, it is desirable to make the display mode different depending on the normally held data in order to save memory area.

In the above embodiment, the present invention has been described using a portable terminal device capable of transmitting and receiving mails as an example. However, the present invention is not limited to information processing devices such as word processors, personal computers, workstations, etc., but also includes a display unit. The present invention can also be applied to various devices such as a copying machine and a printer.

Further, in the above-described embodiment, the description has been given by taking as an example a portable terminal device having a built-in display control program. However, the display control program is recorded on a medium such as a floppy disk, a CD, a memory card, etc. The present invention can also be realized by driving this medium in a personal computer, a laptop personal computer, or a portable terminal device. In this case, a procedure A for inputting information in accordance with the operation of the input means, a procedure B for setting an operation mode in accordance with the information input in this procedure A, and a duration in which the input means is not operated for a predetermined time Is exceeded, the display is stopped. If the input means is operated while the display is stopped, the display corresponding to the operation mode set in step B is restored when the display is stopped. When the display of the operation mode is restored, a program for executing the procedure D for displaying an image clearly indicating the operation mode is recorded on a medium.

[0171]

According to the present invention, the display is stopped when the duration during which the input means is not operated exceeds a predetermined time,
When the input means is operated while the display is stopped, the display corresponding to the operation mode set when the display was stopped is restored, and an image that clearly indicates the operation mode is displayed.
Therefore, when the display screen is restored by the screen save function, the operation can be promptly resumed even if the operation mode immediately before the display stop is forgotten.
