摘要:
An IC tag unit, for an instrument, which allows an IC tag into and from which instrument information, calibration information, inspection information, and the like can be written and read to be mounted to an instrument without affecting the IC tag by a metal portion of an instrument body, hindering visibility of a scale of the instrument, and further causing degradation due to dust, raindrops, or the like, and an instrument with the IC tag, are provided. An IC tag 11 having an IC chip 12 and an antenna 13, and mounting means configured to mount the IC tag to an instrument, are provided, and the instrument has scale increments and a pointer, and a transparent cover plate 53 that covers the scale increments 56a and the pointer. The mounting means includes: a first sheet disposed on an outer side surface of the instrument; a second sheet that is disposed on an inner side surface of the instrument and that sandwiches the IC tag; and an attachment layer that allows both the sheets attached to each other to be attached to the transparent cover plate. The IC tag is disposed between both the sheets so as not to overlap the scale increments 56a and an indicator portion 55a of the pointer 55 in a viewing direction, and a developed plane of the antenna is arranged along both the sheets, when the IC tag is mounted to the transparent cover plate.
摘要:
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.
