Embodiments of the present invention will be explained in detail based on the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes an equal dividing ruler according to the present invention, and the entirety thereof is formed into a flat and elongated shape. A scale display section 4 is provided on one side edge 3 of the ruler main body 2 along the longitudinal direction.

Therefore, the equal division line drawing ruler 1 according to the present invention includes an input means 5 for inputting a length dimension value and an equal division value N, and a division method using the length dimension value and the equal division value N. Calculation means 6
and a scale display section 4 having a ruler scale electrode 7 for displaying an equal dividing line G whose mutual interval dimension is the calculated value of the calculation (division) performed by the calculation means 6. and the electrode 7.
. . . switching means 8 for increasing or decreasing the number of display electrodes F . . . that constitute the equal dividing line G . The input means 5 inputs 1 to 9 and O by pressing.
The calculation means 6 includes a calculation unit 11 that performs a predetermined division based on the input numerical value, H, and a calculation unit 11 that temporarily stores the calculated value of this calculation. and a memory 12 for storing data. The scale display section 4 has ruler scale electrodes 7 which are scale lines, and liquid crystal is used for the ruler scale electrodes 7, for example. Specifically, by arranging liquid crystals in the shape of a scale, and applying a predetermined voltage to a certain part of the liquid crystal, the reflectance of the liquid crystal in that part changes, making it visible from the outside. It is something. Therefore, based on the calculated value of the calculation performed by the calculation means 6 (equal dividing line G...
In order to visibly display G, a predetermined voltage is applied to the ruler scale electrodes 7 corresponding to the equal dividing line G, so that the electrode 7 appears brighter than the other electrode 7. (hereinafter referred to as "display electrode F"). In this case, only the display electrodes F... may be made to change their color so that they can be distinguished from the other electrodes 7....

The number of display electrodes F constituting the equal dividing line G can be selectively changed by the changeover switch 17 of the changeover means 8. In the illustrated example, the display electrode F.
. . indicates an odd number (see FIG. 5), but it may be an even number (see FIG. 6), or may be one. Note that the calculation means 6 The drive device 18 and the like are built into the ruler main body 2, but the numerical formula 9...
. . , and display sections 14 and 15 for displaying input numerical values are arranged outside the ruler main body 2. 19... is the equal dividing line G.
. . . are display keys for displaying on the scale display section 4, 10, 20, and 21 are operation keys for performing division, multiplication, and addition, respectively, 22 is an operation execution key, 23 is a clear key, 24 is a power switch.

Next, in order to enter the above-mentioned length dimension value and the equal division value N, it is possible to do so by pressing the corresponding one among the above-mentioned numerical formula keys 9.... At this time, by pressing the calculation key 10 and the calculation execution key 22, respectively, L+N
The calculation section 11 performs the division. The calculated value of this calculation is temporarily stored in the memory 12, but when the display key 19... is pressed, a signal from the calculating section 11 causes the display section 4 to display a mutual distance dimension D equal to the calculated value.
An equal dividing line G of... is displayed. This equal dividing line G
As mentioned above, a predetermined voltage is applied to a predetermined ruler scale electrode 7..., and the display electrode F... is brighter than other parts.
, and the user can use the corresponding equal dividing line G.
By marking the interval dimension D... on another object, such as paper or an iron plate, with a suitable writing instrument, the equal dividing line G can be drawn.
By configuring . . . with a plurality of display electrodes F. can be seen clearly. In addition, the position C to be marked according to the equal dividing line G is determined by the central electrode F if the equal dividing line G is an odd number of display electrodes F; The intermediate portions of the two electrodes F and F correspond to these, respectively. Incidentally, in the above, by pressing the display key 13, the numerical values ``R'' and ``N'' can be displayed on the display sections 14 and 15, respectively. Similarly, the calculated values can be displayed on one of the display sections 14 and 15 using the display key 19, respectively.

Unlike the case of the above-mentioned embodiment, it is also possible to input the mutual interval dimension and the numerical value corresponding to the above-mentioned equal division value N, and display the equal division line G on the scale display section 4. For example, although not shown, if you want to display 15 lines with a spacing of 3.2, enter these numbers using the number input key 9, and press the calculation key 20 and execution key 22 for multiplication. and causes the calculation means 6 to perform calculation processing. Also, the seventh

...Display it on the screen.

Note that the scale lines of the ruler scale electrodes 7 may be used as a general scale by pressing the clear key 23 and the calculation execution key 22, respectively.

For example, if a dimension of 32 mm is required, input the numerical value and press the calculation execution key 22 and the display key 19, respectively, to display a 32-dragon scale line. Note that, instead of providing a plurality of display keys 19, only one display key 19 may be provided so that all the equisector lines G, . . . can be displayed by pressing this key.

As mentioned above, the interval dimension D... of the equally divided 1jlG... displayed by the display electrode F... is based on the calculated value calculated by the calculation means 6, so it is not necessary to use the conventional method. Compared to the method of attaching marks according to the graduations of a scale when viewed with the naked eye, even items that cannot be read on the scale are displayed at accurate positions, so there are no errors.

As in the embodiment shown in FIG.
