Abstract
A measuring instrument that reads a measure including a plurality of reading patterns arranged in a length direction of the measure, each reading pattern including a plurality of patterns arranged in a width direction of the measure, includes: a flattening member that increases a flatness of the measure; and a first reader that optically reads the plurality of patterns arranged in the width direction included in a single reading pattern from the measure in a state where the flatness is increased by the flattening member.
Claims9
A measuring instrument that reads a measure including a plurality of reading patterns arranged in a length direction of the measure, each reading pattern including a plurality of patterns arranged in a width direction of the measure, comprising:
- a flattening member that increases a flatness of the measure;
- and
- a plurality of first readers arranged in the width direction, that optically read the plurality of patterns arranged in the width direction included in a single reading pattern from the measure in a state where the flatness is increased by the flattening member.
A measuring instrument that reads a measure including a plurality of reading patterns arranged in a length direction of the measure, each reading pattern including a plurality of patterns arranged in a width direction of the measure, comprising:
- a reel around which the measure is wound;
- and
- a first reader that optically reads the plurality of patterns arranged in the width direction included in a single reading pattern from the measure in a state where the measure is wound around the reel.
A measuring instrument that reads a measure including a plurality of reading patterns arranged in a length direction of the measure, each reading pattern including a plurality of patterns arranged in a width direction of the measure, comprising:
- a pressing member that presses the measure;
- and
- a first reader that optically reads the plurality of patterns arranged in the width direction included in a single reading pattern from the measure in a state where the pressing member presses the measure.
A measuring instrument that reads a measure including a plurality of reading patterns arranged in a length direction of the measure, each reading pattern including a plurality of patterns arranged in a width direction of the measure, comprising:
- a flattening member that increases a flatness of the measure;
- a first reader that optically reads the plurality of patterns arranged in the width direction included in a single reading pattern from the measure in a state where the flatness is increased by the flattening member;
- a first case that stores the measure;
- and
- a second case that stores the first reader and is detachable to the first case.
A measuring instrument that reads a measure including a plurality of patterns arranged in a width direction of the measure, comprising:
- a first reader that optically reads the plurality of patterns;
- and
- a corrector that corrects signals read by the first reader so as to compensate for a difference between a plurality of distances, in a direction where the measure and the first reader face each other, between the measure and the first reader at positions where the plurality of patterns are provided.
A measuring instrument that reads a measure including a plurality of reading patterns arranged in a length direction of the measure, each reading pattern including a plurality of patterns arranged in a width direction of the measure, comprising:
- a first reader that optically reads the plurality of patterns arranged in the width direction;
- a second reader that optically reads a plurality of patterns arranged in the length direction;
- and
- a corrector that corrects a length obtained from a reading result of the first reader, based on a reading result of the second reader.
