A measuring instrument includes: a measure on which a code having color patterns is printed; a plurality of first readers that optically read colors of first ranges in first patterns corresponding to digits except a least significant digit among the color patterns, the first ranges in the first patterns being arranged in a second direction; and a plurality of second readers that optically read colors of second ranges in second patterns arranged in a first direction corresponding to patterns of the least significant digit among the color patterns, the second ranges being arranged in the first direction at an interval different from a width of the pattern in the first direction.

Measuring instrument, optical reader and optically-readable measure

A length measuring instrument for measuring length with a measure includes: a measure on which a code is printed, a plurality of patterns each allotted to a different number being arranged, each of the patterns having digits to which an N-notation number (N being 3 or greater) is allotted, each of the digits having a different color corresponding to the allotted numerical value, the patterns being arranged in ascending order or descending order, a Hamming distance between patterns adjacent to each other in an array direction being 1, an amount of change in numerical value at the same digit between the adjacent patterns being 1 in the code; a reading unit that optically reads patterns printed on the measure; and a measuring unit that measures a length of a measurement target from a result of the reading by the reading unit.

Length measuring instrument, code, and code conversion method

A wireless communication device includes: a power storage element configured to store an electric power generated by a power generation element; and a processor configured to: calculate a power storage speed of the power storage element from a temporal change in a voltage of the power storage element; estimate a power generation amount of the power generation element based on a power consumption corresponding to a setting of wireless communication, and the power storage speed; and perform the setting of wireless communication according to the estimated power generation amount.
