Claims

[Scope of utility model registration request]

A drum having a length that can reach a predetermined depth in the sea, around which a wire with a weight and a fishhook attached to the tip is wound, and a detection means for detecting the length of the wire being fed out and hoisted, and the drum. A brake and clutch mechanism connected via a rotating shaft and equipped with a clutch that controls on/off rotation of the drum and a brake that stops and holds rotation of the drum, and drives the drum in forward and reverse rotation through the brake and clutch mechanism. The hook guides the electric motor and the wire that is attached to the tip of the arm and is fed out from the drum, and detects when a fish bites the hook attached to the tip of the wire and dives, and also detects when the fish migrates while biting. A load stress detection device detects when the load becomes light and controls switching of the clutch and brake as well as the rotational direction of the drum to instruct the feeding and hoisting operations of the wire; The device is equipped with a control circuit and a notification means for determining and notifying when a heavy load has been caused by biting and when a light load has occurred in that state, and a control circuit that detects the load state applied to the fishhook and controls the drum. This is an automatic pole and line fishing device for tuna that controls the direction of rotation and automates the feeding and hoisting of the wire when a fish bites. It comprises an air cylinder on which a fishing hook wire is hung through a pulley, a detection means for detecting the protruding length of the piston rod of the air cylinder, and a pressure regulator for adjusting the air pressure supplied to the air cylinder. A load stress detection device for an automatic pole and line fishing device for tuna, characterized in that the load stress applied to the load stress detection device can be freely changed by adjusting the air pressure of the air cylinder.
