1. A sensor for measuring motor function, comprising:
- a magnetic field generator configured to be attached to a first human finger and to generate a magnetic field by electrification supplied from outside, the magnetic field generator having a first plastic body, a first coil board covered with the first plastic body, and a first pin which is integrally provided on the first plastic body;
a magnetic field detector configured to be attached to a second human finger and to output electric current corresponding to a change of distance between the magnetic field generator and the magnetic field detector by relative motion therebetween and to a strength of the magnetic field generated in the magnetic field generator, the magnetic field detector having a second plastic body, a second coil board covered with the second plastic body, and a second pin which is integrally provided on the second plastic body; and
a plastic band configured to be attached to one of the first and second human fingers while covering the magnetic field generator or the magnetic field detector associated with the one of the first and second human fingers;
wherein the plastic band has a plurality of through holes and is configured to be detachably attached to one of the first and second pins by passing the first pin of the magnetic field generator or the second pin of the magnetic field detector associated therewith through a first through hole of the plurality of through holes, winding the plastic band around the finger, and passing the first pin or second pin through a second through hole of the plurality of through holes while covering the magnetic field generator or the magnetic field detector associated with the one of the first and second human fingers,wherein the plastic band overlaps itself with the second through hole overlapping the first through hole with the first pin or second pin passed through the first through hole and second through hole when the plastic band is wound around the finger,wherein the plurality of through holes comprises a first through hole row consisting of through holes arranged in a direction in which the plastic band can be wound around the first or second human finger and a second through hole row consisting of other through holes arranged in the same direction as the through holes of the first through hole row, wherein the second through hole is in one of the first through hole row or second through hole row,wherein the first and second through hole rows are arranged side by side, in a direction of an axis of the first or second human finger,wherein there is only one pin arranged as the first pin in the magnetic field and as the second pin in the magnetic field detector respectively, andwherein each of the first and second pins can pass through any hole of any of the first through hole row and the second through hole row when each of the first and second pins passes through the first through hole and second through hole while the plastic band is wound around the finger.

Abstract
This invention provides a sensor or its related art to be easily used for measuring motor function of living body. This invention relates to a sensor for measuring motor function, which includes a magnetic field generator attached to one of two predetermined positions in a living body changing mutual distance caused by an action of the living body to have a coil board generating a magnetic field by electrification, and a magnetic field detector attached to the other of the two predetermined positions in the living body to detect the magnetic field generated by the magnetic field generator and have the coil board generating an electric current having a magnitude corresponding to a strength of the magnetic field as detected. Furthermore, each of the magnetic field generator and the magnetic field detector is provided with plastics covering a whole coil board thereof.
