Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention directly measures a percentage for inputting to a camera, a scanner, a copying machine, etc. in photoengraving, and also performs layout and trimming in the production of graphic design and production of a printing plate. In doing so, it relates to a device for directly measuring the percentage of expansion or contraction in a proportional manner. (The name of the invention was made into a survey instrument, but this is a coined word by the inventor.)

[0002]

2. Description of the Related Art In a copying machine, a plate-making camera, a monochrome / color scanner, a paper-baking machine, etc., when the original size of an object is enlarged or reduced to a required size, the machine must be manually adjusted to an arbitrary percentage. I have to type in.

Therefore, in the past, the percentage of enlargement or reduction was measured by the following method, but a person was instructed to give the percentage for matching the print size required for the original size photograph or illustration. The case will be described.

1. First, a straight-line 0 point is placed on the left side of the desired object on the original, then the scale on the right side is read and stored.

2 After pressing the key of the calculator to input the numerical value of the required size, press the "÷" key.

3 Next, on the left side of the original size of the original, a straight-line 0
Place a point, then read the scale on the right side and remember it.

4. After inputting the numerical value of this original size by pressing the key of the calculator, the key of "=" is pressed.

5 When the output number is multiplied by 100,
This number is a percentage.

For example, in an article on a central newspaper (page 28) of a newspaper, the number of photographs is 100 to 150, the number of illustrations is 10 to 20, and logos and designated characters are 80 to 120.
Points, and when an advertisement is added to this, the score will be more than double the above number. Considering cases of leaflets, catalogs, public relations, weekly magazines, etc., it is the current situation that a huge number of percentages are put out every day in Japan and around the world.

However, the act of memorizing a numerical value and reading a scale by a direct rule is one of the weakest tasks of human beings. There are individual differences, so even if you can manage to score 7 to 10 points, if you get 20 points, you will not like it. Despite the simple work, you have to keep using your brain and eyes, so if you have a lot of points, your eyes get tired and your memory becomes uncertain. As a result, mistakes are easy to make, and if you notice it, try again, and if you do not notice it, the wrong percentage will enter the scanner or camera, and you will only notice it at the stage of plate collection.

Such a failure not only wastes materials, but also wastes time and delays the delivery date. Therefore, the operator is reluctant to work and loses his willingness to work. It can happen.

[0012]

Therefore, the present invention eliminates errors such as misreading of scales, wrong memory, wrong pressing of keys, etc. performed by humans, and the percentage measurement is performed quickly and accurately. It is an object of the present invention to provide a device that motivates work without giving physical and mental fatigue.

SUMMARY OF THE INVENTION According to the present invention, two sliders each having a protruding bar are fitted and inserted at the front and rear sides of a main scale having a fixed bar at one end, and both sliders are connected by a circuit. The desired span (A) is fixed with the slider bar of No. 2, the original span (B) is fixed with the other slider bar, and the original span (A) is fixed with each slider.
The numerical value of each span of B is displayed in each display column (A) and (B) of the display unit, and the built-in integrated circuit having a calculation capacity of A ÷ B × 100 = percent is used to determine the percentage of expansion or reduction of the span to be obtained. It is displayed in the display field (C) of the display unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a method of using the device of the present invention will be described.

1 Slide the slide bar on the main scale for the desired span to match the desired span (length, interval) S'on trimming. The value of the span to be obtained is displayed in the column A of the display section, but while the slider is sliding, the number in the middle of the progress appears while changing in the column A, and when the slider stops, the value in the column A at that time is displayed. The numerical display is fixed.

2 Next, a slide bar on the main scale for the original span is slid to match the original span S on the trimming.
The numerical value of this original span is displayed in the B column of the display section, but while the slider is sliding, the number in the middle of the progress appears while changing in this B column, and when the slider stops, the B column at that time is displayed. The numerical display is fixed. The desired span S ′ and the original span S are on the same diagonal line.

3 As described above, when the numerical values of the respective spans are fixed in the columns A and B of the display section, A ÷ B is directly calculated.
The calculation of × 100 is performed, and the numerical value of percentage is displayed in the C column.

In this way, if it is on trimming, the percentage obtained in two steps can be obtained. However, for the convenience of the steps, the trimming is attached to the master plate and the manuscript is attached separately. You can use this method.

When it is desired to obtain an arbitrary percentage value and span from the original span, the slide bar for the original span is fixed, and the slide bar for the desired span is slid to appear in the percentage column (C). You can see the actual span you want at the same time as you display the value you want in column A if you match it with the value you want to see.

Therefore, according to the present invention, A / B =
Not only the calculation of C but also the calculation of B × C = A and A ÷ C = B is possible.
