A 15-digit liquid crystal display 136 equipped with a horizontally elongated display window 135 is provided at the upper center of the keyboard section 2 as a display means, and displays the characters and characters input by key.
The symbol data is displayed sequentially from the left to the right, and the cursor moves to the right one character at a time, but when it is filled with 15 characters of data, the cursor is displayed one character off the right edge of the display 136. When the 16th character data is input, all the data on the display 136 is shifted to the left, and the leftmost character/symbol overflows from the display 136.

When used in normal type mode (text mode), this typewriter operates in three modes: direct print mode, collection print mode, and non-print mode (hereinafter referred to as DP mode, CP mode, and NP mode, respectively). It is made operational. In DP mode, key input data is displayed on the LCD display 13.
6, and recording is performed on the recording paper 28 at the same time as the key input, similar to a normal typewriter. In the CP mode, recording is not performed while the key input data is displayed on the liquid crystal display 136. In this mode, recording is not performed on the paper 28, but recording is performed in order from the data overflowing from the liquid crystal display 136. In this CP mode, if the operator notices an input error while key-input data is being displayed on the LCD display 136, he or she can move the cursor on the LCD display 136 to correct the problem by operating the cursor keys 138 and 140. Corrections can be made by moving the code key 126 to another location and operating a key that is operated together with the code key 126 and functions as an insert key 142 or a delete key 144. The NP mode is a mode in which key-input data overflows from the liquid crystal display 136 and is not recorded on the recording paper 28, and is similar to the CP mode except for this. Switching between these three modes is performed by operating the mode key 150, and when the clear key 148 is operated, the liquid crystal display 136

The currently selected print mode is displayed as guidance around the liquid crystal display 136, but in the graph mode, the size key 158 and the belt key 16
2 function as keys for selecting the size and orientation of the graph, respectively.

FIG. 5 shows a control circuit that controls the operation of the recording section 4 and the liquid crystal display 136 in accordance with the inputs from the keyboard section 2 described in detail above. In the figure, 164 is a CPU (central processing unit), and the keyboard section 2 is connected to this CPU 164. Further connected to the CPU 164 are a ROM (read only memory) 166 and a RAM (random access memory) 168. ROM16

Here, text memory 152, graph memory 186, and latest graph memory 188 constitute data storage means.

The latest graph memory 188 is for storing numerical data and necessary subscript data (hereinafter also collectively referred to as graph data) that are key-input when the graph mode is set. This memory mode stores a plurality of pieces of graph data transferred from the latest graph memory 188.
Note that when the graph key 154 of the keyboard section 2 is operated together with the code key 126, the most recent graph data, that is, the latest graph data, is called up from the latest graph memory 188 to the liquid crystal display 136;
You can modify or draw graph data without having to transfer graph data to and from the computer.

Furthermore, when the various graphs, tables, and figures (hereinafter simply referred to as graphs) are stored in the graph memory 186, the text memory 152 also stores pattern data representing one special symbol as shown in FIG. is beginning to be remembered. This special symbol, which should also be called a graph symbol, is of the same level as the character data input by key.
Character/symbol pattern memory 172 of ROM 166
The pattern data is stored in the CPU

Next, the entire program of the typewriter constructed as described above will be explained based on the schematic flowchart shown in FIG.

First, press step S at the same time as operating the power switch.
1 is initialized and the type mode is set to non-memory mode, step S2 is repeatedly executed to wait for a key operation. In this state, if the memory mode setting key is operated, that is, the "M" alphabet key 100 and the code key 126 are operated simultaneously, the process will proceed to step S.
4, the memory mode is set, and if the memory release key is operated, that is, the "E" alpha key 100 and the code key 126 are operated simultaneously, step S6 is executed and the memory mode is released. It will be done.

Further, if the graph key 154 is operated, step S10 is executed to determine whether or not the graph mode is in effect, but since the type mode is at this stage, the graph mode is set in step S11. Furthermore, steps S12 to S
14 is executed, and this point will be described later. Note that if the graph key 154 is operated in the graph mode, step S
10 is YES, and the process goes to step S15.
is executed. In other words, after data is input, it is determined whether or not the graph key 154 has been operated. If the mode is changed to the graph mode and then returned to the type mode, steps S16 to S19 are skipped, and such operation of the graph key 154 has no effect. There is. On the other hand, in the graph mode, if the graph key 154 is operated after data input, step S
The judgment result in step S15 is YES, and the process proceeds to step S16.
to S19 are executed, and this point will be described later.

Further, when the graph key 154 and the code key 126 are operated at the same time, the latest graph processing in step S9 is executed, and this point will also be described later.

Each mode set as described above is determined in steps S20, S21, and S24, and based on the results of these determinations, the mode is set in step S2.
2, S23, S25 and S26 are performed. The operation when the graph mode is set in the memory mode will be described with reference to the flowchart of FIG. 14. However, in Fig. 14, to avoid complexity,
Steps related to input guidance display for instructing the operator on input procedures are omitted.

Now, let us consider the case where graph data is input in order to record an overwritten bar graph as shown in FIG. In the case of this graph, the number of comparison data is 4 items from group 1 to group 4, and the total number of data is 01 to 01 for each of those 4 items.
There are 12 items due to the 3 items in item 03. Therefore, the 11th
Assuming a table as shown in the figure, each cell of the virtual table is assumed to contain numerical data from groups 1 to 4. The display window 135 of the liquid crystal display 136 is capable of displaying numerical data for one square of this virtual table, as shown in FIG.
38 and 140, that is, keys that function as the cursor left key and cursor right key when operated alone, and as the cursor up key and cursor down key when combined with the code key 126, are located on the left and right sides of the display window 135 in the graph mode. , is designed to function as a virtual table for specifying the positions of the cells that are assumed to be above and below.

Now, when the graph key 154 is operated as described above, steps S10, S11, S12 and S14 in the flowchart of FIG. Display 13
6, a display asking about the type of graph will be displayed.
Numerical key 104 correspondingly indicates the number "3"
is operated, step S22, that is, the fourteenth
The routine shown in the figure is executed.

First, the determination result in step S101 becomes YES, and "3" is stored in the input buffer memory 180 and displayed on the liquid crystal display 136 in step S110. Next, when the return key 110 (hereinafter simply referred to as the enter key 110) as an enter key is operated, the process proceeds to step S1.
The judgment results of 00 and S117 are YES,
In step S118, an overlapping bar graph is selected. Next, in response to the display asking for the number of comparison data, total data, etc., those preliminary data are input in the same way and stored in the latest graph memory 1.
88.

Next, as shown in FIG. 15, guidance is displayed on the LCD display 136 indicating that the data of group 1 will be imported, and by operating the enter key accordingly, the first numerical data of group 1 will be imported as shown in FIG. You will be asked to enter the following. Numerical data that can be entered is up to 8 digits, including negative data. Numerical data entered by key is displayed on the liquid crystal display 136, for example, as shown in FIG. Similarly, enter key 110
is stored in the latest graph memory 188 by the operation. The latest graph memory 188 (the graph memory 186 is similar) is a series of 8-bit storage elements of one unit, as conceptually shown in FIG. Similarly, input data of the enter key is also stored as 8-bit code data. That is, it is determined in step S117 whether or not data has been input. In this case, since numerical data has been input as described above, step S118 is executed and the enter key 110 is pressed as shown in FIG. The input data is the latest graph memory 1 as boundary data.
88, and one group of numerical data up to the boundary data is stored in (D1-) of the virtual table shown in FIG.
01) is stored as data that should fit within the box.

Similarly, as shown in FIGS. 18 to 21, concrete numerical data is input in response to the question that the second and third data of group 1 should be input, so that step S101 is performed. , S110, S100, S117 and S118 are repeatedly executed to
The third data and the third data are taken in, but if the enter key 110 is operated after inputting the last numerical data of group 1, that data is stored and as shown in FIG. A guidance message saying "Enter data input for group 2" is displayed, and when the enter key 110 is operated again, the LCD display 136 asks for the first data of group 2, as shown in FIG. A display is made. Here, since the operation of the enter key 110 after the guidance display shown in FIG. 22 does not involve data input, the determination result in step S117 is NO, step S119 is executed, and the enter key input data in that case is is stored in the latest graph memory 188 as line feed data. That is, as shown in FIG. 13, when two consecutive pieces of data are input to the enter key 110, this means line feed data. The following similar steps are executed,
Numerical data of three items each for Group 2, Group 3, and Group 4 are also stored in the latest graph memory 188 with boundary data and line feed data as described above.

After that, you can select whether to add hatching as additional item data, title names, X-axis names, Y-axis names, group names of groups 1 to 4, and label names for each block as shown in Figure 10. , necessary subscript data, etc. are input sequentially in the same interactive format as in the case of the numerical data described above, and these data are also stored in the latest graph memory 188. It is assumed that it is attached to the bottom of the virtual table and has a form similar to a table. When all the graph data have been input, a message to that effect is displayed on the liquid crystal display 136.

When the graph key 154 is operated in accordance with this display, the determination result at step S7 in the flowchart of FIG. 7 becomes YES, and step S1
0 is executed, but since the graph mode is at this stage, step S15 is executed.
Since the numerical data has been input as described above, the judgment result in step 15 is also YES.
Step S16 is executed to determine whether or not the memory mode is present. If it is not in the memory mode, steps S17 and S18 are skipped and the graph mode is canceled in step S19, but since the memory mode is set here, step S17 is executed and the latest graph memory 188 is saved. Contents are graph memory 18
6 is stored. However, the latest graph memory 18
8 data is left without being cleared. FIG. 13 is also a diagram conceptually showing the graph memory 186 in which the contents of the latest graph memory 188 are recorded. Subsequently, in step S18, data of a special symbol indicating the existence of a graph is stored (this special symbol is a so-called dead character and is not printed even when character/symbol data in the text memory 152 is printed). , and after that special symbol is displayed on the liquid crystal display 136 as shown in FIG. 8, the graph mode is canceled in step S19.

The above is the operation when newly inputting graph data.Based on the special symbol data stored in the text memory 152, the corresponding specific graph data is displayed on the liquid crystal display 13.
6 and can be modified if necessary. Each time special symbol data is stored in the text memory 152 or is called from there, the instruction of the graph pointer in the CPU 164 is changed, and the graph indicated by this graph pointer is changed. data is read out from the graph memory 186. This point will be explained below.

First, in the type mode, place the cursor under the special symbol displayed on the liquid crystal display 136 as shown in FIG.
54 is operated, the determination result at step S7 in the flowchart of FIG. 7 becomes YES, and the determination result at step S10 becomes NO. Therefore, the graph mode is set in step S11,
Subsequently, steps S12 and S13 are executed. The display of data in the text memory 152 of the liquid crystal display 136 is cleared, and the data in the graph memory 186 corresponding to the above-mentioned special symbol is called up according to the instructions of the graph pointer, and the graph is first displayed in the display window 135 of the liquid crystal display 136. A number indicating the type will be displayed. Next, by operating the cursor down key, that is, by simultaneously operating the cursor key 140 and the code key 126, steps S114 and S116 in FIG. 14 are executed, and after displaying preliminary data such as the number of comparison data, the virtual table is displayed. The numerical data in the box at the top left is the second
It is displayed in the display window 135 as shown in FIG.
This display is performed with the lowest digit of the numerical data "450" being shifted to the right end of the display window 135, and a message display indicating what the data represents being shifted to the left end. This message display is based on the display pattern memory 1 of the ROM 166.
76 along with the above-mentioned question pattern display, etc., and the CPU 164 stores it in the graph memory 1.
The numerical data read from 86 and the message display pattern read from display pattern memory 176 are combined and displayed on liquid crystal display 136.

In this state, when the cursor right key is operated once, the CPU 164 executes steps S111 and S116, and the data is stored next to the numerical data corresponding to (D1-01) in the graph memory 186 shown in FIG. Numerical data corresponding to (D1-02) is read out by searching the second boundary data and displayed on the liquid crystal display 136 together with the message display as shown in FIG. Also, in this way, (D1−02) of the virtual table
When the cursor down key is operated, that is, the cursor key 140 and the code key 126 are operated simultaneously while the square corresponding to is displayed,
The CPU 164 executes steps S114 and S116, searches the graph memory 186 shown in FIG. 13 for the first line feed data, and converts the numerical data stored before the second boundary data from this line feed data into the virtual table. Numerical data corresponding to (D2-02) is displayed on the display window 135 as shown in FIG.

In this way, depending on the operation of the cursor right key, cursor left key, cursor up key, and cursor down key, the determination results in steps S102 to S105 become YES, and steps S111 to S11 are performed.
4 and step S116 are executed, and the data in any one square of the virtual table is displayed on the display window 135. From the operator's perspective, as conceptually shown in FIG.
It appears as if the display window 135 has moved to the left, right, top and bottom of the virtual table. Therefore, even though the display window 135 is small, by freely scrolling the display window 135 to each cell of the virtual table, it is possible to easily grasp the entirety of the numerical data, and also when corrections are necessary. It is also useful for finding the problem. Incidentally, subscript data such as the title name and label name mentioned above and preliminary data such as the number of data can also be called up in the display window 135.

Regarding the correction of the numerical data of each square in the above virtual table, for example, as shown in Figure 25 (D1-02)
If the clear key 148 is operated while the square data corresponding to If you operate the enter key after inputting data, the new corrected numerical data will be replaced with the previous numerical data and the graph memory 186 will be replaced with the corrected new numerical data.
is memorized. That is, in the flowchart of FIG. 14, the determination result of step S106 is
YES, and in step S115 the input buffer memory 180 and the display buffer memory 1 are
82 is cleared, the above-mentioned question is asked again, and then steps S101 and S
New numerical data is stored in the graph memory 186 through steps 110, S100, S117 and S118. It should be noted that all preliminary data such as subscript data and number of data other than numerical data can be modified except for the type of graph.

When the correction is completed and the graph mode is canceled by operating the graph key 154, the display on the liquid crystal display 136 will be replaced by the data display in the text memory 152 including special symbols, as shown in FIG. It is also possible to execute step S108 by operating the start key, that is, by simultaneously operating the space key 106 and the code key 126, and draw the graph data using the corrected graph data.

Note that it is possible to make corrections by scrolling the display window 135 to each square on the virtual table as described above, not only in the graph data editing mode, but also when creating a new virtual table with data already entered. The same applies to the table.

Further, when the graph key 154 and the code key 126 are operated at the same time, step S9 in the flowchart of FIG. 7 is executed, and the latest graph memory 188 is called. As aforementioned,
Regardless of whether it is in memory mode or non-memory mode, when new graph data is input, the latest graph memory 1 is stored in step S14.
88 is specified, but in this case, it is necessary to first select the graph type, and at the same time, all the contents stored in the latest graph memory 188 (previously input graph data) are selected. cleared. On the other hand, when the latest graph memory 188 is called by executing step S9, its stored contents are not cleared, and the cursor right key, cursor left key, cursor up key,
The desired data in the latest graph memory 188 is displayed on the liquid crystal display 13 by operating the cursor lower key.
6, and the data can also be edited. Of course, it is also possible to draw the graph based on the graph data in the latest graph memory 188.

Additionally, as if the guidance showing major headings as shown in Figures 15 and 22 were placed on the left side of the virtual table in Figure 11, the virtual table's cells should be placed in an extra column on the left. Assuming that when those squares are specified by scrolling the display window 135,
It is also possible to have the CPU 164 read out the guidance display pattern data from the display pattern memory 176 of the ROM 166 and display it on the display window 135.

Furthermore, in the above explanation, the clear key 148
However, when the cursor left key or cursor right key functions as an operation means for specifying the left and right cells of the virtual table, there is a key operation means that can separately move the cursor left and right within the display window 135. If provided, the cursor can be moved to the location of the numerical data displayed in the display window 135, and the insert key 142 or delete key 144 can be pressed.
By the operation, it is also possible to modify data in the same way as in the case of characters in the text memory.

Regarding the special symbol indicating the existence of the graph shown in FIGS. 8 and 9, when the special symbol is displayed in the liquid crystal display 136, the delete By operating the key 144, the display of the special symbol is erased and the text memory 152 is
It is possible to erase the special symbol data in the graph memory 186 and erase the graph data corresponding to the special symbol in the graph memory 186, but the graph data is erased after waiting for another key operation. It can also be done. In addition, by making it possible to enter the code data of the special symbol using a dedicated key or a specific key operation, the symbol data can be input into character/symbol data in the text memory 152 in combination with the operation of the insert key 142. It is also possible to insert the graph anywhere in the graph and change the graph insertion position freely.

In addition, in the explanation based on FIG.
Previously, the input data of the Enter key was stored as line feed data, but even if boundary data is uniformly stored between numerical data, the number of groups and items of data to be input can be determined in advance. If so, for example, when the cursor down key is operated, the numerical data stored next to the predetermined number of boundary data from the boundary data of the current data is read out, and the display is performed in the same manner as described above. is possible.

Furthermore, although the above explanation uses an overlaid bar graph as an example, similar virtual tables can be assumed for overlaid line graphs, stacked bar graphs, band graphs, and radar charts, and simple bar graphs and In the case of a pie chart, it is similar to other rough charts except that each group has one piece of data in FIG. 11. In addition, in the case of numerical data in a table, the difference is that the table itself to be created is assumed to be a virtual table as it is, but other aspects are the same as in the case of graphs.

Additionally, assuming a virtual table as described above and displaying graph data as if the display window 135 were to move around on the virtual table, it is difficult to research the data stored in the graph memory 186. Although this is convenient, it is not essential, and the data may be displayed as if the data groups were arranged horizontally or vertically. Further, the display means is not limited to a liquid crystal display, and can be replaced with various other devices including an electroluminescent display, a fluorescent display tube, and the like.

Further, the special symbol indicating the existence of a graph is not limited to the one illustrated in FIG. 6, but can be selected from various symbols that can be easily distinguished from ordinary characters. Further, if the latest graph memory 188 is provided as in the above embodiment, it is possible to copy the latest graph without performing memory operations, which is a preferable aspect, but if it is omitted, can also enjoy the benefits of the present invention.

It goes without saying that the present invention can be implemented in other forms with various modifications and improvements based on the knowledge of those skilled in the art.
