Abstract
A spool brake device for a fishing reel includes an electric spool brake, a rotation detector, and a controller. The rotation detector detects a rotation of the spool. The controller calculates a rotational velocity of the spool based on the rotation of the spool, determines whether the fishing reel is in a casting state based on the rotational velocity, controls the spool brake to brake the spool upon a determination that the fishing reel is in the casting state, and controls the spool brake to not brake the spool upon a determination that the fishing reel is not in the casting state.

A spool brake device for a fishing reel, the spool brake device configured to brake a spool of the fishing reel, the spool brake device comprising:
- a spool brake configured to brake the spool in an electrically controllable manner;
- a rotation detector configured to detect a rotation of the spool;
- and
- a controller configured
- to calculate a rotational velocity of the spool based on the rotation of the spool,
- to determine whether the fishing reel is in a casting state based on the rotational velocity,
- to control the spool brake to brake the spool upon a determination that the fishing reel is in the casting state, and
- to control the spool brake to not brake the spool upon a determination that the fishing reel is not in the casting state.
A method for controlling a spool brake device of a fishing reel, the method comprising:
- calculating a rotational velocity of a spool;
- determining whether the fishing reel is in a casting state based on the rotational velocity;
- controlling the spool brake to brake the spool upon a determination that the fishing reel is in the casting state;
- and
- controlling the spool brake to not brake the spool upon a determination that the fishing reel is not in the casting state.
A spool brake device for a fishing reel, the spool brake device to brake a spool of the fishing reel, the spool brake device comprising:
- an electric spool brake;
- rotation detecting means for detecting a rotation of the spool;
- and
- spool brake controlling means for calculating a rotational velocity based on a signal from the rotation detecting means, for determining whether the fishing reel is in a casting state based on the rotational velocity, for controlling the spool brake to brake the spool upon a determination that the fishing reel is in the casting state, and for controlling the spool brake to not brake the spool upon a determination that the fishing reel is not in the casting state.
