Abstract

PURPOSE:To improve the working efficiency of an electronic equipment by scrolling only the file names out of a subject and referring the selected file names at all times in a list on a screen. CONSTITUTION:Plural file names stored in a storage means are shown by a display means (S1). The file name that is designated by an operator via a designating means and processed by a data processing means is excluded out of those file names to be erased by an erasion excluding means so that the relevant file name is never erased by a display changing means (S14-S16). Furthermore, a display change inhibiting means inhibits the change of display when the number of designated file names reaches the limit number of file names of the display means. Therefore, the designated file names are never erased out of the display means and can always be visually confirmed (S12-S13).

In this example, the number of lines that can be displayed on the screen is 10, and the upper 2 lines and the lower 1 line are used for a message to the operator. Therefore, up to 7 file names can be displayed. The files are TEXT1 to TEXT10.
Consider the case where there are 10 files. In this case, the initial state of the file index screen is as shown in FIG. That is, the seven file names TEXT1 to TEXT7 are displayed on the screen, and the first file, TEXT1
The block cursor 60 is located above.

In this state, when the file deletion process is performed to delete a plurality of files, the lower cursor moving key (not shown) is pressed to move the block cursor 60 onto the file name to be deleted. Then, by pressing the space key, the corresponding file name is selected and highlighted. For example, TEXT2, TEXT6, TEXT
If you want to delete 3 files of 9, first use the cursor down key and space key to move the text
The block cursor 60 is moved while selecting EXT6. As a result, it becomes as shown in FIG. Here further
To display and select a file (TEXT9) outside the display range, press the down cursor movement key twice. As a result, it becomes as shown in FIG. That is, the screen scrolls to newly display two file names outside the display range, and the two file names displayed at the top of the screen move and are erased from the screen. TEXT here
When 9 is selected and the file name selection processing ends, FIG.
As in (d), a list of selected file names is displayed to confirm deletion.

[0004]

However, in the above conventional electronic device, the file name (TEXT2) selected at the stage of FIG. 8C scrolls and disappears from the screen, and all the files selected for deletion are deleted. The only way to confirm the name was to display a list after finishing the selection process. Therefore, if you do not notice the selection error, or if you notice the selection error in the list display, you can restart the process as shown in Figure 8.
I had to reselect from the state of (a). Therefore, the operation is complicated and the work efficiency is deteriorated.

The present invention has been made in order to solve the above-mentioned problems, and the selected file name is not erased from the screen, and only the file name not covered is scrolled to select the selected file name. The purpose is to always be able to list. Furthermore, if the selected file name fills the screen, the selection process is automatically suspended temporarily so that the selected file name is not erased from the screen during the selection process in any case. ..

Since the configuration of the printing mechanism PM is publicly known, its description is omitted here.

Next, the overall configuration of the control system of the word processor 1 will be described with reference to FIG. The word processor 1 basically includes a keyboard 3, a display section DM, and a printing mechanism P.
The keyboard 3, the printing mechanism PM, and the display unit DM are connected to the control unit C through the input / output interface 33. The display unit DM includes a display controller 30 connected to the input / output interface 33 and a liquid crystal display 8. The liquid crystal display 8 displays characters and the like via the display controller 30 which is drive-controlled by the control unit C described later. It is done.

The control unit C comprises a CPU 35, an input / output interface 33 connected to the CPU 35 via a bus 34 such as a data bus, a ROM 40 and a RAM 50. The ROM 40 stores various programs and the like, and the program memory of the ROM 40 has a hidden scrolling program 41, which will be described later,
A file name selection processing program 42, a program 43 for controlling the display section DM in correspondence with code data input from the keyboard 3, a program 44 for document data editing processing, and other various programs necessary for controlling the word processor are stored. ing.

In the RAM 50, an all file name area 51 for storing all file names, a selected file name area 52 for storing the selected file name, a scroll reference position area 53 for storing a reference position for hidden scrolling,
A deletion processing work area 54 used for the deletion processing work is provided. Next, the file deletion processing control performed by the control unit C of the word processor 1 will be described with reference to the flowchart of FIG. In the figure, Si (i = 1,
2, 3) are each step.

Here, the conditions such as the screen size and the example file name are assumed to be the same as those described in the prior art. When the file deletion process is designated, the file names stored in the entire file name area 51 of the RAM 51 are sequentially displayed on the screen of the liquid crystal display 8 from the first file name (S).
1). Next, the scroll reference position of RAM 51 (hereinafter,
0 is written as an initial value in the area 53 (abbreviated as BL) (S2). Further, the block cursor 60 is displayed on the displayed top file name (S3). Therefore, the state of the screen at this time is as shown in FIG. Here, the operator waits for an instruction by key input from the keyboard (S4). When there is a key input, it is determined what the key is (S5). If the key is the down cursor movement key (S5: YES), the block cursor 60
Since the upper file is not selected, the file name is hidden in the BL line and scrolled (S19), and the key input waiting state is returned (S4). That is, if the down cursor movement key is input in the state of FIG. 4, TEXT
Since one file is hidden in the BL (= 0) line, it is erased from the screen of the liquid crystal display 8 and the next TEXT2 file is displayed on the screen of the liquid crystal display 8 and the block cursor is displayed on it. 60 is displayed, as shown in FIG.

If the entered key is not the down cursor movement key (S5: NO), it is determined whether it is the space key (S6). If so (S6: YES), it means that the file on the block cursor 60 is selected (S14). Therefore, the file name is written in the selected file name area 52 of the RAM 50 and displayed on the screen of the liquid crystal display 8. The file name is displayed in reverse (S
15). Then, the value of BL is incremented by 1 (S16), and the BL is compared with the maximum number of lines that can be displayed on the screen (S1).
7). If BL is smaller (S17: YES), another file name can still be displayed, so block cursor 6
0 is displayed on the file name one line below. When this space key is input after FIG. 5, TEXT2 is selected, so that it becomes as shown in FIG.

If the entered key is neither the space key nor the return key, it is judged (S7). If it is not the return key (S7: NO), it means that a key input error has occurred, and the buzzer sounds (S20) and the key input waiting state is restored (S4). Return key (S7: Y
ES), it is determined whether or not the file name already selected exists in the selected file name area 52 of the RAM 50 (S8). If the file name exists (S8: YES),
A message is displayed on the message line 62 to confirm whether or not these files can be deleted, and the operator is asked (S9). For example, in addition to the state shown in FIG.
If the return key is input after selecting 6 and TEXT 9, the result is as shown in FIG. If there is no file name in the selected file name area 52 of the RAM 50 (S
8: NO), since only the file name currently on the block cursor is selected from the file names displayed on the screen, the file name is selected. File name area 5
2 is written (S21), and the file name is displayed in reverse (S22). Then, the operator is asked to confirm the deletion in the same manner as described above (S9).

When the space key is input (S6:
If YES, BL = maximum number of display lines is reached (S17:
NO), that is, when the screen is full of the selected file names, it is confirmed at that stage whether or not the deletion process is to be executed immediately (S9). When the deletion is not executed (S9: NO), the selected file name area 5 of the RAM 50
2 is cleared (S23), all reverse displays on the screen are canceled (S24), and the initial state is restored (S23).
1). RAM to delete (S9: YES)
Deletion processing is performed using the deletion processing work area 54 (S10). After the deletion is executed, it is checked again whether or not the screen is full of the selected file names (S11), and if it is not full (S11: YES), it means that the deletion process is ended by the operator, and the file deletion process control is ended. If it is full (S11: NO), it is judged whether or not there is an undisplayed file name in all the file name areas 51 of the RAM 50 (S12). If not (S12: NO), the deletion processing control is ended. If there is still (S12: YE
S), display the undisplayed file name from the first line (S1
3) The deletion processing control is repeated in the same manner as above (return to S2).

As described above, when the operator considers whether or not to select the file (TEXT9) that is initially outside the display range, the already selected file names (TEXT2, TEXT6) are confirmed on the screen. Since it is possible, it is possible to prevent mistakes such as the selection criteria changing in the middle. Further, the present invention is not limited to file names, but can be applied to any information as long as it gives information to a large number of data of the same type, such as directory names and user names. Although the word processor has been described in the present embodiment, it can be applied to other electronic devices such as a personal computer.

[0020]

As is apparent from the above description, in the electronic device of the present invention, the selected file names can always be listed on the screen by scrolling only the non-targeted file names. Therefore, the work efficiency can be improved. Furthermore, when the screen is filled with the selected file name, the selection process is automatically suspended temporarily, so the selected file name is not erased from the screen during the selection process in any case. Can be configured.
