Abstract

A method for a dual-bearing reel includes detecting a rotational speed of a spool rotatably mounted to a reel unit, a fishing line to be wound about the spool, controlling a spool brake to brake the spool with a first braking force when a detected tension that acts on the fishing line is equal to a reference tension controlling the spool brake to brake the spool with a braking force obtained by correcting the first braking force based on a second braking force when the detected tension and the reference tension are different from each other, the second braking force positively or negatively correcting the first braking force by increasing or decreasing the first braking force, and performing a decrease processing of decreasing the second braking force with the elapse of time when the second braking force has been determined to fluctuate with a predetermined amplitude or greater.

Dependent claims

A spool brake device for a dual-bearing reel, the spool brake device to brake a spool, the spool rotatably mounted to a reel unit, a fishing line to be wound about the spool, the spool brake device comprising:

a spool brake configured to brake the spool in an electrically controllable manner;
a first braking force setter configured to set a first braking force;
a speed detector configured to detect a rotational speed of the spool;
a tension setter configured to set a reference tension;
a tension detector configured to detect a tension that acts on the fishing line;
a second braking force setter configured to set a second braking force, the second braking force for positively or negatively correcting the first braking force by increasing or decreasing the first braking force;
and
a spool controller configured to control the spool brake with the first braking force when a detected tension detected by the tension detector and the reference tension are equal to each other, the spool controller configured to control the spool brake with a braking force obtained by correcting the first braking force based on the second braking force when the detected tension and the reference tension are different from each other,the spool controller configured to perform a decrease processing of decreasing the second braking force with the elapse of time when the second braking force has been determined to fluctuate with a predetermined amplitude or greater.
