Abstract

A dual bearing reel includes a reel unit having a handle and mounted on a fishing rod, a spool in which a fishing line is mounted, and a spool braking device mounted on the reel unit so as to be at least partially exchangeable with another spool braking device. The spool is rotatably mounted on the reel unit so as to be rotatable by the handle. The spool braking device includes a spool braking portion that brakes the spool according to a first predetermined braking characteristic, and a first device identification portion that indicates the first predetermined braking characteristic. The user can confirm the braking characteristic of a spool braking device when the spool braking device is exchanged with another spool braking device having a different braking characteristic.

Claims

1. A spool braking device adapted to be exchangeably mounted in a dual bearing reel, the spool braking device being adapted to brake rotation of a spool and comprising:

a spool braking portion that is adapted to brake the spool according to a predetermined braking characteristic;

a spool control portion that is operatively coupled to the spool braking portion and configured to control the spool braking portion; and

a device identification portion that indicates the predetermined braking characteristic.

2. The spool braking device set forth in claim 1, wherein

the spool braking portion includes

a rotor that is arranged in a rotational direction of the spool, the rotor including a plurality of magnetic poles whose polarities are sequentially different,

a plurality of serially connected coils that are arranged around the circumference of the rotor, and

a switch connected to both ends of the plurality of serially connected coils, and

the spool control portion includes a circuit board on which the plurality of coils are mounted.

3. The spool braking device set forth in claim 2, wherein

the circuit board includes a program according to which the predetermined braking characteristic is determined.

4. A dual bearing reel adapted to be mounted on a fishing rod, comprising:

a reel unit having a handle and adapted to be mounted on the fishing rod;

a spool in which a fishing line is adapted to be mounted, the spool being rotatably mounted on the reel unit so as to be rotatable by the handle; and

a first spool braking device mounted on the reel unit so as to be at least partially exchangeable, the first spool braking device having

a first spool braking portion that is adapted to brake the spool according to a first predetermined braking characteristic, and

a first device identification portion that indicates the first predetermined braking characteristic.

5. The dual bearing reel set forth in claim 4, wherein

the first spool braking device includes a first spool control portion that is operatively coupled to the first spool braking portion and configured to electrically control the first spool braking portion.

6. The dual bearing reel set forth in claim 5, wherein

the first spool control portion is configured to set a braking force with which the first spool braking portion brakes the spool in accordance with a type of the fishing line mounted on the spool.

7. The dual bearing reel set forth in claim 5, wherein

the first spool braking portion includes

a rotor arranged in a rotational direction of the spool the spool, the rotor including a plurality of magnetic poles whose polarities are sequentially different and rotates in association with the spool,

a plurality of serially connected coils are disposed spaced apart from the rotor, and

a switch connected to both ends of the plurality of serially connected coils, and

the first spool control portion includes a circuit board on which the plurality of coils are mounted.

8. The dual bearing reel set forth in claim 7, wherein

the circuit board includes a program according to which the predetermined braking characteristic is determined.

9. The dual bearing reel set forth in claim 4, wherein

the first spool braking portion is configured to assume one of a plurality of braking patterns,

the first spool braking device further includes a first indicator portion which allows a user to select one of the plurality of braking patterns, and

the first identification portion includes a color of a surface of the first indicator portion.

10. The dual bearing reel set forth in claim 4, further comprising

a second spool braking device mounted on the reel unit so as to be at least partially exchangeable with the first spool braking device, the second spool braking device having

a second spool braking portion that is adapted to brake the spool according to a second predetermined braking characteristic, and

a second device identification portion that indicates the second predetermined braking characteristic.

11. The dual bearing reel set forth in claim 10, wherein

the first and second spool braking devices are of a same type.
