74882号の実用新案として出願している。
Conventional length measuring instruments equipped with a scale disc as described above have the disadvantage that the number of revolutions of the scale disc is displayed by a gear-type counting device, resulting in a complicated device structure and high cost. It was hot. Therefore, in order to eliminate the above-mentioned conventional drawbacks, the applicant has developed a scale disk.
He devised a length measuring device that could count the number of revolutions corresponding to a length of 10 cm by counting the number of times the swinging body operated.
It has been filed as a utility model No. 74882.
