Abstract

A braking device for a dual-bearing reel for braking a spool rotatably mounted on a reel body, includes a spool brake and a spool controller. The spool brake is configured to brake the spool by electromagnetic induction during casting of a fishing line. The spool controller is configured to control a braking force of the spool brake by controlling an ON/OF-state of current that is generated due to the electromagnetic induction at a prescribed period. The spool controller has a period changer configured to change the prescribed period for braking the spool.

Claims

1. A braking device for a dual-bearing reel for braking a spool rotatably mounted on a reel body, comprising:

a spool brake configured to brake the spool by electromagnetic induction during casting of a fishing line;

a spool controller configured to control a braking force of the spool brake by controlling an ON/OF-state of current that is generated due to the electromagnetic induction at a prescribed period; and

a rotation detector configured to detect rotational information of the spool,

the spool controller further comprises a rotational seed calculator configured to calculate the rotational speed of the spool based on the rotational information of the spool and the spool controller having a period changer configured to change the prescribed period for braking the spool in accordance with the rotational speed of the spool.

2. The braking device for a dual-bearing reel according to claim 1, wherein

the spool controller further comprises a maximum speed recognizer configured to recognize a maximum rotational speed of the spool based on time-series data of the rotational speed of the spool, and

when the rotational speed of the spool is lower than the maximum rotational speed, the period changer changes the prescribed period for braking the spool.

3. A braking device for a dual-bearing reel for braking a spool rotatably mounted on a reel body, comprising:

a spool brake configured to brake the spool by electromagnetic induction during casting of a fishing line; and

a spool controller configured to control a braking force of the spool brake by controlling an ON/OF-state of current that is generated due to the electromagnetic induction at a prescribed period,

the spool controller having a period changer configured to change the prescribed period for braking the spool,

the spool controller further comprises a rotational speed setter configured to set a rotational speed for changing a period based on the prescribed period for braking the spool, and

the period changer is configured to change the prescribed period for braking the spool based on the rotational speed for changing the period.

4. The braking device for a dual-bearing reel according to claim 3, wherein

when the rotational speed of the spool is within a prescribed range including the rotational speed for changing the period, the period changer changes the prescribed period for braking the spool.

5. The braking device for a dual-bearing reel according to claim 4, wherein

the spool controller further comprises a deceleration determiner configured to determine whether the rotational speed of the spool has decelerated based on the rotational speed of the spool, and

when the rotational speed of the spool is decelerating and is within the prescribed range, the period changer changes the prescribed period for braking the spool.

6. The braking device for a dual-bearing reel according to claim 4, wherein

the spool controller has a period setter configured to set the prescribed period for braking the spool to a specified value, and

when the rotational speed of the spool is not within the prescribed range, the period setter sets the prescribed period for braking the spool to the specified value.
