The present invention, to measure the thickness, width and length of a flat plate-shaped subject such as a particle board, to specify the measurement point defined by the standard, dimensions to be used detachably attached to the subject The present invention relates to a measuring jig and a dimension measuring system using the same.

In the particle board factory, in order to inspect whether the thickness, width and length of the manufactured particle board meet the Japanese Industrial Standards, measurement based on JIS standard “JIS A 5908” is performed. ..

In the JIS standard, measurement points for the thickness, width and length of the particle board are defined, and the measurement points for the thickness are four corners 15 mm or more inside from each side of the particle board. It is stipulated that the measurement location is about 100 mm inside from the periphery, and the width and the length are measured at two locations parallel to each side.

Therefore, in an actual measurement site, the dimension is measured from each side of the particle board which is the object using a measure, and the surface of the particle board corresponding to the measurement point defined by the JIS standard is marked with a pencil or the like. After that, a method of measuring the marking portion with a caliper, a micrometer, or a measure is performed.

Regarding the measurement values obtained by the above-described conventional measurement method, the measurer directly writes the measurement value on the measurement sheet or the assistant reads the measurement value read by the measurer on the measurement sheet. ..

On the other hand, although it is an invention different from the present invention, the “measurement jig 12” described in FIG. 6 of Patent Document 1 and the “measurement jig” described in Patent Document 2 are related arts related to the present invention. is there.
