Abstract
A fishing reel which supports at its body frame a spool freely rotatably by disengagement of a clutch is provided with a first detector which detects a drawing-out speed of a fishing line wound onto the spool, a second detector which detects a rotational speed of the spool, a processor having an arithmetic unit and connecting with the output lines of the detectors, and an actuator operative by an output signal from the processor which controls application of a rotational resistance against free rotation of the spool.
Claims14
A fishing reel comprising:
- a body frame,
- a spool journalled to said frame and having a spool shaft,
- a drive mechanism for driving said spool shaft,
- a transmission mechanism including a clutch, for transmitting a driving force from said drive mechanism to said spool shaft, said transmission mechanism upon operation of said drive mechanism, rotating said spool shaft and spool to wind a fishing line onto said spool, said clutch disengaging to make said spool shaft and spool freely rotatable, so that a fishing line may be drawn out of said spool by casting,
- a first detector for detecting a drawing-out speed of said fishing line on said spool and providing a first signal corresponding thereto,
- a second detector for detecting a rotational speed of said spool and providing a second signal corresponding thereto,
- a processor having an arithmetic unit and connected to receive said first and second signals, said processor comparing said first and second signals and providing an actuator control signal which changes in accordance with changes in said first and second signals,
- means for applying a rotational resistance against the free rotation of said spool shaft and spool, and
- an actuator responsive to the actuator control signal from said processor, said actuator operating according to said control signal when a spool rotational speed exceeds a line drawing-out speed to cause said applying means to apply a rotational resistance against the free rotation of said spool shaft and spool.
