Claims

[Scope of utility model registration request]

(1) A disc rotating at a constant speed, a reference point fixed to a case and provided corresponding to the disc, a reference area that is an area including this reference point, and a reference area provided concentrically with the disc. a rotatable angle-measuring arm; first and second measurement points provided on the angle-measuring arm and located symmetrically with respect to the rotation center of the angle-measuring arm; or calculation means for multiplying the ratio of the angle measurement time for the disk to rotate to the second measurement point and the one rotation time for the disk to make one rotation by 360°, and the first measurement point is within the reference area. a determining means for determining whether or not the first measuring point is within the reference area; measuring the time it takes for the disk to rotate from the reference point to the second measuring point when the first measuring point is within the reference area; a switching means for switching to measure the rotation time of the disc from the reference point to the first measurement point when the point is not within the reference area, and from the angle measurement value when the first measurement point is within the area; An angle measuring device comprising: angle measurement value correction means for subtracting 180°.

(2) An angle measurement time integrating means for integrating an amount corresponding to the angle measurement time for each rotation of the disk; and one rotation for integrating an amount corresponding to the one rotation time for each rotation of the disk. It is characterized by further comprising a time integrating means and a calculating means for calculating the measured angle according to the ratio of the integrated value of the angle measurement time and the integrated value of the one rotation time after a predetermined rotation of the disk. An angle measuring device according to claim (1) of the above-mentioned utility model registration.

(3) The calculating means, the determining means, the switching means, and the angle measurement value correcting means operate when the disk rotates once. The angle measuring device according to item 1).
