A key section 45 is printed in a frame at a position facing ..., and the key section 45 of the basic mode setting key group 37 is printed.
The basic mode name is printed correspondingly.

Further, a transparent member 46 is formed at a position facing the aperture 43 of the processing mode key group 38 so that the item sheet disposed below can be seen through.

One processing mode is designated by the key signal of the basic mode setting key group 37 and the key signal of the processing mode key group 38.

An item sheet feeding mechanism 50 is provided below the contact board of the processing mode key group 38, and a selected block (page) of a long item sheet 51 is positioned in the opening 43.

Next, the item sheet feeding mechanism will be explained with reference to FIG.

53, 54 are side plates, two rollers 55,
56 is rotatably supported, and these rollers 55, 5

A roller drive mechanism is provided on the outside of the side plate 54, and both rollers 55, 56 have driven gears 63,
68 is installed. Further, fixed plates 65 and 66 are provided on the outside of the side plate 54, and a drive gear 61 connected to the rotating shaft of a pulse motor 60 by a timing belt 62 is rotatably attached. A movable lever 67 is provided on the drive gear 61 via a reduction gear 61a, and is moved in the direction of rotation by the rotational moment of the movable lever 67. A transmission gear 64 is attached to this movable movable lever 67, and driving force is transmitted from the drive gear 61 to the transmission gear 64 via a reduction gear 61a. The transmission gear 64 is engaged with the driven gear 63 or 68 by moving the movable lever 67.

For example, when the drive gear 61 rotates in the direction of the arrow (solid line) due to the rotation of the pulse motor 60, the movable lever 67 is also moved in the direction of the arrow and engaged with the transmission gear 64 and the driven gear 63, and the item sheet 51 is moved in the direction of the arrow. will be transferred to.

Further, when the pulse motor 60 is reversed, the drive gear 61 is rotated in the opposite direction to the arrow, the movable lever 67 is also moved in the opposite direction, and the transmission gear 64 and the driven gear 68 are engaged. Therefore, the gear 68 is rotated in the direction of the arrow (broken line), and the item sheet 51 is transported in the opposite direction.

Note that 52 indicates one block (one page) of the item sheet 51.

Next, the long item sheet 51 described above in FIG.
This specifically shows the page structure of item sheet 51, and processing mode names corresponding to basic modes that are relatively frequently used are arranged near page N, which is located approximately in the center of item sheet 51.
Processing mode names corresponding to basic modes that are used less frequently are arranged as the page positions approach both ends of the page from the center of the page.

That is, in FIG. 5, page N contains processing mode names (document registration, document recall,...
In addition, processing mode names (header/footer, extraction classification, ...equal allocation) corresponding to the frequently used basic mode of editing are also arranged on the N+1 page adjacent to the N page. There is.

Furthermore, on page N+n, which is further away from pages N and N+1, processing mode names (character input, type change, ... deletion) corresponding to the figure/graph mode, which is a basic mode that is less frequently used, are arranged, and N- Processing mode names (=, rounding, . . . horizontal calculation) corresponding to calculation modes that are basic modes that are used less frequently are also arranged on page n.

The input/storage mode of the basic mode described above is used after initializing the text processing device or when inputting text, and the edit mode is used when editing a created text, and is used extremely frequently.

On the other hand, the figure/graph mode is used when inputting figures and graphs, and the calculation mode is used when performing four arithmetic operations on numerical values.As a mode for text processing devices, it is used less frequently than the above two modes. low.

The page structure of this item sheet 51 has the processing mode names of frequently used basic modes placed adjacent to each other in the center, making it possible to speed up the selection of corresponding pages by switching between these frequently used modes. Even if the mode is switched to a relatively low basic mode, the item sheet 51 only moves from the center position to one end side, so in this case as well, a situation in which the item sheet 51 moves from one end to the other end is avoided. This method has the advantage that page selection can be performed extremely quickly as a whole.

Next, FIG. 6 shows a block diagram of the control structure of the text processing apparatus of the present invention, and the control operation of the entire apparatus will be explained below. In FIG. 6, 80 is the key block 4 in the keyboard device 4 of FIG.

Reference numeral 83 is a sheet selection circuit for transporting the item sheet 51 to the destination position, and in response to the operation of the basic mode setting key, a page (processing mode name) corresponding to the operated basic mode is selected using the processing mode key. The motors are driven and controlled so as to be placed in positions corresponding to the groups.

84 is a control unit, 85 is a program memory composed of RAM, and this memory 8
The control unit 84 is controlled in accordance with a program stored in the computer 5.

The program memory 85 includes a table area 85a into which data (table) for managing program types to be stored in the memory is loaded from a floppy disk when the device is initialized, and a table area 85a that is loaded from a floppy disk when the device is initialized. Resident area 85 for storing basic program data loaded from the disk, that is, program data for controlling the entire system and program data for frequently used basic modes (input/storage mode and editing mode).
b, and an overlay area 85c that stores corresponding processing program data that is loaded from a floppy disk each time a basic mode that is relatively infrequently used is selected.

86 is a text buffer for storing character data input from the key circuit 80, and 87 is an image buffer for storing image data of figures and graphs. Input to this image buffer 87 is made from a key or an image scanner (not shown).

Reference numeral 88 is a kana-kanji conversion control unit for converting kana characters into sentences mixed with homophones of kanji, and 89 is a control unit for a dot printer 90 (corresponding to printer 3 in Fig. 1), which converts text data in a text buffer or image Printer 9
Print at 0. 91 is CRT display 92 (corresponds to CRT display 2 in Figure 1)
It is a control unit for displaying the text data, image data, and message data to the operator on the display 92.

Reference numeral 93 denotes a control section of a floppy disk device 94 (corresponding to the floppy disk device 5 in FIG. 1), which performs reading or writing from a disk plate 95 attached to the device 94.

The disk board 95 includes a disk board for storing a basic program to be loaded into the resident area 85b of the program memory 85, a disk board for storing a basic mode program to be loaded into the overlay area 85c, and a disk board for storing text data and image data. Among these, the basic program disk board is attached to the device 94 at the time of initialization, and the basic program is loaded into the resident area 85b. Further, the disk board of the basic program which is used relatively infrequently is always attached to the device 94 after initialization.

FIG. 7 is a flowchart showing operations related to the operation of the basic mode setting key group 37,
Now, when any key in the basic mode setting key group 37 is operated, an input signal (mode type data) based on the key operation is latched.

Next, it is determined whether the operated basic mode is a frequently used mode. In other words, in this example, the frequently used input/storage mode (K ₁ )
Then, it is determined whether or not the edit mode (K ₂ ) is in effect.

Now, the above-mentioned K ₁ which is frequently used in the above-mentioned judgment
and _K2 , the sheet selection circuit 83 is directly driven to feed the item sheet 51, and the target page corresponding to the input basic mode is positioned corresponding to the processing mode setting key group 38. .

After that, it is checked whether the selected basic mode program is loaded.
After the frequently used basic mode program is loaded at the time of initialization, it is resident in the resident area 85b of the program memory 85, so that the next key input can be made immediately.

Also, if another frequently used setting key in the basic mode is operated next, the item sheet will be fed and the target page will be selected in the same way as above.
As shown in Figure 5, pages with frequently used processing mode names are adjacent to each other, so the target page is quickly selected, and since this program is also resident, key input is quickly enabled and the device is activated. This will prevent you from being on standby as much as possible.

On the other hand, if a basic mode other than the frequently used basic mode mentioned above is operated, the above K ₁ ,
If the determination is _K2 , the process goes to the NO side, and first an instruction is given to load the operated basic mode program from the floppy disk device into the overlay area 85c of the program memory 85. In response to this instruction, the control unit 93 of the DMA and floppy disk device 94 executes program loading, feeds the item sheet 51, and selects the processing mode setting key group for the target page corresponding to the input basic mode. 38.

Thereafter, it is checked whether the program loading of the selected basic mode is completed, and if it is completed, the next key input becomes possible.

A program corresponding to this basic mode, which is used relatively infrequently, is loaded from a floppy disk, and during this loading, pages of the item sheet 51 are selected for efficient control.

In this case, the page selection is performed by moving from the frequently used mode, and the page is selected by feeding the item sheet in one direction from the center of the item sheet, so the time required for this selection is short. In addition, in general, the selection of the basic mode is such that when switching from the input/memory mode or editing mode described above to calculation mode or figure/graph mode, the next mode is switched again to the input/memory mode or editing mode. In many cases, switching operations from calculation mode to figure/graph mode or vice versa are quite rare. Therefore, by using the page structure shown in FIG. 5, efficient page selection can be performed.

Furthermore, since the basic mode programs that are used infrequently are selectively loaded each time from an external storage device (floppy disk device), a large capacity internal memory is not required; Time item sheet 51
Page selection can be made.

<Effects> As described above, in the present invention, the character key section for inputting characters, symbols, etc. and the control key section for setting various processing modes are configured at different positions on the keyboard surface. The control key section includes a first input section for setting and inputting one of a plurality of basic modes in which processing modes are roughly classified, and a second input section for setting and inputting a processing mode belonging to a lower level of the major classification corresponding to the major classification.
and an input section, and the second input section assigns a plurality of processing mode names for defining each key of this input section to one or more blocks (pages) for each of the major classifications, and assigns the plurality of processing mode names to one or more blocks (pages) for each of the major categories. A plurality of item sheets, and in response to selection of one of the basic modes of the first input section, a block in the item sheet corresponding to the input basic mode is corresponded to each key of the input section. A drive mechanism is provided at a defined position for selection, and the above-mentioned character key portion and the first
By integrally providing the input section and the second input section, even if the number of processing modes increases due to high functionality, the number of blocks on the second input section will simply increase, and the keyboard surface will be reduced. It is possible to prevent an increase in the number of keys, and the operability of selecting the processing mode is made easy by having two stages of the first input section and the second input section,
The keyboard device can be made compact in spite of being a multi-functional device.

In addition, as for the block (page) structure in the item sheet of the second input section, blocks with processing mode names corresponding to frequently used basic modes are arranged adjacent to each other, and blocks of the frequently used basic modes are arranged adjacently. By arranging blocks with processing mode names corresponding to basic modes that are relatively infrequently used in the center before and after it, this page selection, that is, switching between basic modes, can be made faster and the waiting time of the device can be shortened. A text processing device that can handle faster processing can be obtained.
