[Technical background of the invention and its problems]

In recent years, there are document creation devices that create and display a character string or a graphic at an arbitrary position on a CRT screen by using a bit-mat memory, and in these document creation devices, a device such as a tablet, a keyboard, or a keyboard is used as a device to position on the CRT screen. A pointing device called a mouse is used. In addition, a mark called a grid is displayed on the CRT screen as a guide for facilitating the position specification, and the position specifying operation is performed by the pointing device. However, by just using this grid as a guide, it is accurate and beautiful,
In addition, it was very difficult to make documents efficiently. In other words, in order to draw parallel lines, draw a three-dimensionally visible plan view, or create groups of figures and character strings at equal intervals, you must tell the number of grids and find the correct position. Nakatsuta.

Therefore, it is very difficult to arrange the character strings and figures on the paper surface cleanly and efficiently in the conventional document creating apparatus.

[Object of the Invention]

The present invention has been made in consideration of such circumstances.
The purpose is to write a character string or figure on a paper, usually on a desk, with a straight line ruler, a triangle ruler, or a drafting machine. Display this as an electronic ruler on the CRT screen,
An object of the present invention is to provide a document creation device which can be used in combination with a pointing device to create a layout of figures and character strings neatly and quickly.

[Outline of Invention]

The present invention displays a scale (ruler) on the CRT screen, and the scale can be moved to any position on the screen by the scale moving unit. Further, a mark can be attached to the scale for display, and the scale can be moved in parallel or rotationally to facilitate the pointing. In addition, the scale can be a right-angled ruler by instructing it, or the moving direction can be fixed to facilitate parallel movement.

Further, it is possible to consider the marking position on the scale as the input position of the pointing device and execute it. Also, by storing the figure creation command in the scale and executing the marking position, the figure creation can be performed temporarily. It is possible to perform, and moreover, a plurality of marks and graphic commands can be defined so that they can be selectively executed.

〔The invention's effect〕

Therefore, according to the present invention, it is possible to create and instruct the arrangement of a figure or a character string on the CRT screen by the scale moving unit and the pointing device as if the figure and the character string were written on paper with a ruler and a pencil. it can.

That is, it is possible to save the trouble of counting the number of grids as in the conventional art, to perform the pointing more easily and accurately, and to reuse the position marked on the scale. Also, by registering commands, straight lines,
Since the circles can be created at equal intervals and with the same size by one execution operation, the troublesomeness of the conventional graphic creation and position designation can be solved, and a great effect is practically achieved.

Example of Invention

An embodiment of the present invention will be described below with reference to the drawings. 1 (a) and 1 (b) are schematic configuration diagrams of the apparatus of the embodiment,
2 and 3 are detailed configuration diagrams of the scale data analysis unit 2 of FIG. FIG. 4 is an external view of the device of the input unit that controls the scale. Reference numeral d-1 is a lever for moving the moving direction of the scale in an arbitrary left / right / up / down direction. The scale can be rotated by rotating d-1. By rotating the lever d-1 while pushing the d-2 switch, the right half of the scale can be rotated clockwise and counterclockwise.
Similarly, by rotating the lever d-1 while pressing the d-3 switch, the left half can be rotated clockwise and counterclockwise. This state is shown in FIG. 6 and the original scale shape is b-1, but the lever d-1 is rotated 90 ° clockwise while pushing the switch d-3 in FIG. By doing so, the shape of the scale is b in FIG.
-2 state.

In FIG. 5, a-1 shows the state of the original scale, a state of a-2 shows the state in which the lever d-1 is moved to the lower right direction, and a state of a-3 shows the scale a. -1 shows a state in which the lever d-1 is rotated counterclockwise by an arbitrary angle.

The values for changing the scale movement and rotation and the angle of the scale shape described above are set by the input unit for controlling the scale shown in FIG. This is a portion corresponding to the scale movement input unit 1 in FIG.

The switch for setting the moving direction of the scale is d-5. By pressing the switch d-5, it is possible to input the numerical data (specifically, how many times the scale can move relative to the reference line) from the input unit 4 in FIG. The numerical value of the section 4 is also input to the scale data analysis section 2 from the input data analysis section 5. The data input to the scale data analysis unit 2 is the movement direction setting unit 15 in FIG.
Is set to. The value set once is held until the set value release switch d-7 is input. When the moving direction is set, the scale moves only in the set direction even if the lever d-1 is moved in the left / right / up / down arbitrary directions.

Further, by pressing the switch d-6, the moving amount of the scale can be set. When the switch d-6 is input, as in the movement direction setting, a numerical value indicating how many units (or how many metric units) the scale is to be moved is input from the input section of FIG. The input numerical value is input to the scale data analysis unit 2 via the input data analysis unit 5. Further, this data is input to the movement amount setting unit 16 in FIG. As a result, by moving the lever d-1, the scale moves in a set numerically separated manner, for example,
When set to 10 mm, the movement is corrected so that the scale moves in units of 10 mm in the movement direction. By setting the movement amount after setting the movement direction, the scale can be fixedly moved only in a certain direction.

Next, the case of rotating the scale will be described. By rotating the lever d-1, the scale can be arbitrarily rotated with respect to the reference point and displayed. This state is shown in a-3 of FIG. Lever d-1
When d is rotated, d-4 detects the rotation direction, that is, the scale movement input unit 1 in FIG. 1 detects the rotation and sends the data to the scale data analysis unit 2. The details are shown in FIG.

The scale rotation direction detector 17 identifies the rotation direction data. Further, by pressing the switch d-8, the angle of the rotation direction can be set. The rotation angle (for example, + 30 °) from the input unit 4 is the same as that set in the moving direction.
By inputting, the input data analysis unit 5 inputs the value to the scale data analysis unit 2. The rotation direction setting unit 18 of FIG.
The scale is rotated and displayed according to the angle specified in.

Further, by pressing the switch d-9, the rotation amount can be set from the input unit 4. If, for example, 30 ° is input from the input unit, this value is input to the scale data analysis unit 2 via the input data analysis unit 5. Here, it is further input to the rotation amount setting unit 22, and the input data is held.
The rotation angle when the scale lever d-1 is rotated is detected by the scale rotation direction detection unit 17, and the detected value is compared with the previously held value and the detected value is set. It is corrected to be a multiple of the value and output to the scale display data creation unit 21. For example, if the set value is 30 ° and the detected value is 40 °, the rotation angle is corrected to 30 °, and if the detected value is 50 °, the rotation angle is corrected to 60 °. That is, when the set value is X and the detected value is Y, the quotient of Y / X is n.
If the value obtained by multiplying X by n and subtracting the value from Y is larger than X / 2, the value of (n + 1) × X is given as a correction value,
If it is smaller, the value of n × X is given as the correction value.
With this configuration, the rotation angle of the lever d-1 allows the rotation angle to be discretely operated in units of set values. This arithmetic unit is shown in FIG.

Next, an embodiment in which the scale angle is changed will be described. By pressing switch d-2 and rotating lever d-1, the lever d-1 is rotated with respect to the right half of the scale.
The angle is changed by the rotation angle of. Switch d-d
By pressing, the scale movement input unit 1 identifies the ON signal of the d-2 switch, and this signal is input to the scale data analysis unit 2. This signal is used by the scale angle setting unit 19
When the lever d-1 is rotated, the gate circuit 20 prohibits output of the lever rotation signal to the scale display data creation unit 21 in order to restrict the operation to change the angle. To do.

Instead, the scale angle setting unit 19 reads the output of the scale rotation direction detection unit 17, identifies that the rotation operation of the lever d-1 is the operation of changing the scale angle, and outputs the output data and d- From the information of the two switches, it is determined how many times the scale angle should be changed, and the result is output to the scale display data creation unit 21.

Similarly, when the d-3 switch is pressed, the angle of the left half of the scale can be changed.

The above describes a detailed example of how the scale operates on the screen.

Next, a detailed example of the operation for displaying the mark on the scale will be described.

There are several features to display marks on the scale.

Specify a range on the scale, and display a mark on the scale so that the range is divided by the specified numerical value.

The mark is displayed in the specified unit (for example, several mm unit) on the scale.

When creating a figure, move the scale to the position on the display screen where you want to create the figure. Then, on the scale, the position required to create the figure (for example, if you want to draw a straight line,
Move the cursor to the end point position) and enter the position specification command for this cursor position. Then, a mark is displayed at the cursor position on the scale. FIG. 5 shows how marks (x) are displayed on the scales 0 and 3 on the scale.

When the figure command is input together with the position designation command in (3), the designated position (the position where the mark is displayed) on the scale and the figure command are stored in association with each other. For example, when a straight line command is input, this and the start point / end point positions (two mark positions on the scale) are stored.

The mark indicating the figure command stored in and the figure name are displayed in the scale. This mark is the same as the mark displayed at the designated position on the scale (the position on the scale designated by the position designation command input together with the figure command). For example, in FIG. 8, a mark (x) indicating a straight line command is displayed as (x ... Straight line) at the right end of the scale together with the figure name (straight line). This mark (x) is the same as the two marks (x) at the start point and end point displayed on the left side of the scale.

When a plurality of types of graphic commands are input and the positions are specified on the scale for each, different marks are displayed at these positions corresponding to the graphic commands. For example, as shown in FIG. 7, when the center point and the circumference point of the circle are first designated on the scale with respect to the circle command, a C-1 mark (◯) is displayed on them. Next, when the start point and the end point of the straight line are designated on the scale, the mark (x) of C-2 is displayed on them.

When the execution command is input for the figure command and the designated position data stored in step 3, the figure is displayed according to the scale position on the display screen. For example, when the scale is displayed at the position of d in FIG. 8 and the execution command of the circle is input, a circle is drawn with the two marks (◯) positions on the scale as the center point and the circumference point ( (Dotted line in FIG. 8). Further, when a plurality of commands and respective designated position data are stored, these can be selectively executed. In the scale of FIG. 8, a circle command and a straight line command can be selected and executed.

Examples of the above are described below.

FIG. 1 When a scale range designation command is input from the input unit 1, the scale data analysis unit 2 is passed through the input data analysis unit 5
Entered in. This command is held in the equally divided data analysis unit 23 in FIG.

Next, the position designation is input from the input unit 4 in order to designate the range on the scale. In this case, two range positions are input while moving the cursor. This information is input to the scale data analysis unit 2 and sent to the position designation command detection unit 26 shown in FIG. Here, it is checked whether the range position designation is on the scale. This process will be described in more detail.

FIG. 10 shows a display memory in which data is stored for displaying scale or document data on the display unit 7, and a certain portion on the display memory is defined by being divided into a scale data writing area and a document data writing area. . Then, by defining which address of the display memory corresponds to which of the display section (CRT screen) to display, the scale data and the document data can be displayed together on the same screen. A table in which the display memory and the addresses of the display section are associated with each other exists in the display control section 6 as a mapping table in FIG. For example, when there is an operation to move the scale on the screen, the scale display control unit 3 changes the value in the mapping table of the display control unit 6 so that the display appears to have moved.

FIG. 12 shows the details of the display control unit 6. The scale data table shown in FIG. 13 stores where the scale data is written in the display memory. That is, when the scale angle is changed, the display memory can be displayed on the display unit 7 by updating the display memory address of the scale data table and updating the mapping table at the same time.

As can be seen from the above description, in the range check of whether or not the specified position is within the scale, first, the input position specification is input as the position on the screen from the input unit 4 and the input data analysis unit 5 displays the screen. This can be detected by reversely searching the mapping table of FIG. 11 from the position, detecting the display memory address, and comparing the scale data table of FIG. 13 with the address. As a result, if the position is on the scale, the position is transferred to the equal division control unit 24. Next, similarly input the second point on the scale from the input unit 4,
The position is held in the equal division control unit 24. Further, a numerical value indicating how to divide the input first point and second point is input from the input unit 4, and the input data analysis unit 5 is provided to the equally divided data analysis unit 23. As a result, the equal division control unit 24 performs equal division processing of the range of the two input points by the equal division numerical value to detect the display memory address position corresponding to the divided point position, and the mark type classification unit 29.
In, the type of mark and the address are associated.
At this time, a series of display memory addresses are associated so that they can be divided into the same group. At the same time as sending this value to the storage unit 30, the mark display control unit 31 writes the mark in the corresponding display memory address.

In the above embodiment, two points, the start point and the end point, are input,
You can predefine either the start point, the end point, or both as the reference value and enter only the equally divided values.
You may use the value defined beforehand as a reference value.

Next, an embodiment corresponding to the above function will be described in detail. As a procedure for creating a figure, the command to be created is first input from the input unit 4. For example, to draw a straight line, enter the straight line command. This command is normally input from the input unit 4 through the input data analysis unit 5 to the control unit 8. In the case of a figure command, figure editing section 1
The command is input to 0 and the input point wait state is entered.
The operator moves a desired position cursor while arbitrarily moving the cursor on the screen of the display unit and inputs a position designation command. The input data analysis unit 5 reversely searches the mapping table for the position designation command from the screen address to the display memory address, and the input point is converted into the display memory address. This value is input to the graphic editing unit 10 via the control unit 8. In the case of a straight line command, it is necessary to input the start point and the end point, so
Then, it enters a state of waiting for input of the end point position. Similarly, when the end point position is input to the graphic editing unit 10, the start point and end point positions indicate the display memory position now. This is converted from the display memory address to the address on the document paper, and the correspondence relationship is obtained. Is stored in the correspondence table 12.
Further, the straight line command and the start point and end point positions converted into the paper surface position are stored in the data structure buffer 11. Next, after activating the display editing unit 13 and re-editing into a command sequence which can be interpreted by the display control unit 6 for displaying on the display unit by using the linear command and the display memory address, the display control unit 6 stores in the display memory. Actually write a straight line at.

The above is the procedure until a normal straight line is displayed. If the scale is displayed on the start point and the end point position when the start point and the end point are input after the straight line command is input, the following processing is performed. . That is, when a straight line command is input, the input data analysis section 5 sends it to the scale data analysis section 2 and further enters the figure command detection section 27 shown in FIG. Further, when two points of the start point and the end point are input, they are similarly input to the position designation command detection unit 26 of FIG.
As a result, the linear command, the start point, and the end point position are associated with each other in the associating unit 28, and a series of data is stored in the storage unit 3.
Store it in 0. At this time, in order to display the mark on the scale by specifying the position, the mark type classifying unit 29 also associates the mark type with the data and stores it in the storage unit 30. Then, in order to display the mark on the scale, the mark data and the start point and end point mark positions to be displayed are sent to the mark display control unit 31. Further, as shown in the above-mentioned function, the mark display control unit 31 controls the display control unit 6 to display that the type of mark displayed on the scale is a linear command at an appropriate position on the scale. Send data and display it on the display.

Next, a case will be described in which an execution instruction is issued for the graphic command stored in the storage unit 30 and the data of one row of the position data indicated by the function.

When a storage data execution command is input from the input unit 4, this data is sent to the scale data analysis unit 2 via the input data analysis unit 5, and is further input to the selection unit 32 in FIG. The selection unit 32 searches the storage unit 30 for a group of graphic commands and position data. If only one group is stored, the subsequent graphic command and position data are read out and sent to the execution unit 33. The execution unit 33 first searches the scale data table for where the scale is currently displayed on the screen of the display unit 7, and first obtains the display memory address. Since the position data of the storage unit 30 is the memory address at the time of saving, when the scale is moved during the execution designation, it is different from the stored value. Must be corrected to the position on the memory address in the document area corresponding to. Therefore, the position where the scale is currently displayed is searched as data7 from the mapping table, and at the same time, the display memory address of the document area on the same screen address is searched and supplied to the execution unit 33 as data7. The display memory address and the graphic command of the retrieved document area are transferred to the control unit 8 as data2, and the graphic command can be executed as if they were input from the input unit 4.

In this case, only one graphic command is stored in the storage unit 30, but if a plurality of graphic commands are stored in the storage unit 30, the next candidate command is selected in order from the input unit. Can execute a desired graphic command.

In the above embodiment, the operation of moving and rotating the scale itself, the operation of changing the angle as the shape of the scale, the means for displaying the mark on the scale, and the function for storing and executing the graphic command on the scale are all performed. Although the possible examples have been described, it is not necessary to have all the functions, and the individual functions may be combined.

In addition, although the description has not been given for changing the size, thickness, color, etc. of the scale, the present invention is a means for freely moving the scale on the screen, a means for changing the angle, a means for displaying a mark on the scale, Any means capable of storing graphic commands on the scale may be used.

According to the present invention, it is possible to beautifully, accurately, and efficiently input a graphic or character string at an arbitrary position on the screen by using a scale. Further, in the embodiment of the present invention, the lever is provided with a plurality of switches so that it can be operated while gripping the lever, but this may be input from a keyboard or another input device.

Further, in the present invention, one dot of the display memory is associated with one dot of the display unit in dot units in the mapping table, but it corresponds to several dot units (for example, 32 × 32 dots) when viewed from the container of the table. You may simplify by the method of attaching.

Further, although the display memory is divided into the document area and the scale display area, the scale may be written according to the document area, and the display may be moved while writing the XOR on the memory by movement.

In the embodiment, the mark is provided on the scale, but the scale may be provided in advance.
