IC TAG UNIT FOR INSTRUMENT, IC TAG SYSTEM FOR INSTRUMENT, INSTRUMENT PROVIDED WITH IC TAG UNIT, AND METHOD FOR CALIBRATING INSTRUMENT PROVIDED WITH IC TAG UNIT
To provide an IC tag unit, for an instrument, that can be retrofitted to an analog instrument, that does not impair the calibration state of the instrument, and that can read the value indicated by an indicator and take out the value to outside in a contactless manner.;The IC tag unit includes a scale increment reading module 20 which reads operation of an indicator 55. An IC tag 11 performs wireless communication with a wireless reader 70 via an antenna 13′ and includes a power module which extracts and supplies drive power for the IC tag by electromagnetic wave of the wireless communication. A sheet which holds the IC tag and an attachment layer which attaches the sheet to the transparent cover plate are provided. The IC tag is provided on the sheet at a position where the IC tag is not overlapped, in a viewing direction, with any of scale increments 56a and an indicating portion of the indicator at a time of mounting the IC tag to a transparent cover plate 53. The scale increment reading module includes a sensor 21 which is opposed to the indicator on the sheet and which reads the position of the indicator on the basis of relative movement thereof.
