Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scale capable of quickly and accurately measuring enlargement and reduction during copying. For details, refer to the enlargement / reduction copy scale.

[0002]

[Prior art]

 In the past, in the measurement of enlargement and reduction at the time of copying, it was necessary to perform a troublesome calculation in which each was calculated based on the enlargement and reduction ratio based on the original. This is scaled up and down according to the paper size of the copying machine, so the scale was a halfway number, so it could not be measured with the conventional scale.

[0003]

[Problems to be solved by the device]

 In the measurement at the time of enlarging and reducing, which has been described in the conventional technique, there is a problem that it is troublesome to calculate and easy to make an error.

[0004]

[Means for Solving Problems]

 In order to achieve the above object, the enlargement / reduction copy scale in the present invention is, for example, a deformed quadrangle, and the four faces are used to mark eight places, 87%, 82%, 71%, 61%, The scales are 141%, 122%, 115%, 100%, etc.

Further, the scale depends on the multiplication rate of enlargement and reduction for each sheet built in the copying machine. The relationship between the original size and the paper size when enlarging and reducing is described below.

When the enlargement ratio is 115%, when the document sizes are B4, B5, and B6, the paper sizes are A3, A4, and A5, respectively.

When the enlargement ratio is 122%, when the document sizes are A4, A5, and A6, the paper sizes are B4, B5, and B6, respectively.

When the enlargement ratio is 141%, the paper sizes are A3, A4, A5, B4 and B5 when the document sizes are A4, A5, A6, B5 and B6.

When the reduction ratio is 87%, when the document size is A3, A4, A5, the paper size is B4, B5, B6, respectively.

When the reduction ratio is 82% and the document sizes are B4, B5 and B6, the paper sizes are A4, A5 and A6, respectively.

When the reduction ratio is 71%, the paper sizes are A4, A5, A6, B5 and B6 when the document sizes are A3, A4, A5, B4 and B5.

When the reduction ratio is 61%, the paper sizes are B5 and B6 when the document sizes are A3 and A4, respectively.

With respect to the magnification, 141% is 1 / 70.9, 122% is 81.9 / 1, 115% is 86.9 / 1, 87% is 114.9 / 1, and 82% is 11.7% of 121.9 minutes is set to 1 / 140.8, and 61% is set to 1 / 13.96.

Further, the mold may be a mold in which respective memories are arranged regardless of the shape of the rectangle.

It is also conceivable that the scales of enlargement and enlargement and reduction are combined into one scale.

As the shape at that time, various shapes such as a polygon, a triangle, a flat shape, and the like can be considered. Further, the length may be short or long depending on the intended use.

[0017]

[Action]

 Just by reading the scale of the enlargement / reduction copy scale, it is possible to measure the enlarged / reduced copy and perform work such as drawing.

[0018]

【Example】

 Examples will be described with reference to the drawings. In FIGS. 1 to 6, the enlargement / reduction scale may be a cross-sectional shape having a deformed quadrangle using a plastic such as vinyl chloride resin.

The enlargement / reduction copy scale includes scales and scales of 141%, 122%, 115%, 100%, 87%, 82%, 71%, 61% on each surface of the above-mentioned deformed quadrangle. Is described as in FIGS.

Alternatively, the enlargement / reduction copy scale is scaled by 141%, 122%, 115%, 100%, 87%, 82%, 71%, 61% as shown in FIGS. It is also conceivable to complete the chart.

[0021]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

By using the enlargement / reduction copy scale, it is possible to quickly and accurately measure an enlarged or reduced drawing or the like.

By using the enlargement / reduction copy scale, it is possible to draw an enlarged or reduced drawing as it is.
