とを特徴とする測長装置。[Claims for Utility Model Registration] 1. A belt-shaped tape made of a magnetic material, a tape winding means for winding the tape, and the tape and the tape winding means are installed inside,
a casing having an opening for pulling out one end of the tape; a rotating body of magnets interposed between the tape winding means and the opening of the casing and magnetically engaged with the tape; and a rotating body of the magnets. It is equipped with a counter that measures the amount of tape feed based on the rotation of the tape and displays the measurement result as a digital value.In addition, it is equipped with a bearing that supports the rotating body of the magnet so that it can rotate in both forward and reverse directions. Moreover, between the bearing and the rotating body of the magnet, a non-magnetic material is used to substantially prevent magnetism from the rotating body of the magnet from reaching the bearing by separating the bearing from the rotating body of the magnet. A length measuring device characterized in that a separating member is provided. 2. A belt-shaped tape made of a magnetic material, a tape winding means for winding the tape, and the tape and the tape winding means installed therein;
a casing having an opening for pulling out one end of the tape; a rotating body of magnets interposed between the tape winding means and the opening of the casing and magnetically engaged with the tape; and a rotating body of the magnets. It is equipped with a counter that measures the amount of tape feed based on the rotation of the tape and displays the measurement result as a digital value.In addition, it is equipped with a bearing that supports the rotating body of the magnet so that it can rotate in both forward and reverse directions. A length measuring device characterized in that the bearing is made of a non-magnetic material having a property of not being affected by magnetism from a rotating body of the magnet.
