2. Description of the Related Art In recent years, many fishing reels are equipped with a line length measuring device for measuring the line length (the amount of fishing line or the amount of fishing line) based on the number of rotations of a spool detected by the number of rotations detecting means. The yarn length measuring device can be used to lower the tackle at a predetermined shelf position, or to display the flying distance of the tackle to a point in pitch fishing.

Conventionally, as this type of yarn length measuring device, a plurality of yarn length calculation formulas corresponding to the yarn diameter are stored in advance in a memory of a microcomputer as disclosed in Japanese Patent Publication No. 4-2211. Every time, the thread length calculation formula is selected based on the yarn length calculation formula selected by the angler according to the yarn diameter, and the actual rotation speed of the spool at the time of actual fishing detected by the rotation speed detection means. And those disclosed in Japanese Patent Laid-Open No. 1-276011
As in the yarn length measuring device disclosed in Japanese Patent Publication, the line length calculation formula and the actual number of revolutions of the spool, which are determined by inputting the total number of revolutions of the spool when the fishing line is wound up to the specified winding diameter level, Based on the selection, the thread diameter stored in the memory is selected, such as the thread length measuring device disclosed in Japanese Utility Model Publication No. 3-10859, which enables the thread length to be measured regardless of the type of fishing line used. After that, the line length is measured based on the input total line length of the fishing line and the actual number of rotations of the spool, and when the detection signal from the number of rotations detection unit is not output to the microcomputer for a predetermined time, the number of rotations detection unit Various yarn length measuring devices are known, such as one that automatically cuts off the power supply to the battery to increase the life of the battery power source.
