[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle for arranging an electric motor and a planetary speed reduction mechanism inside a rotating body for winding a fishing line, and for manually winding the fishing line and the speed reduction mechanism. In a state where the reverse rotation operation of the transmission system is prevented, the driving force of the electric motor is reduced and transmitted to the rotating body to drive the rotating body in the fishing line winding direction so as to drive the rotating body in the fishing line winding direction. And an electric reel having a clutch mechanism disposed in a transmission system between the handle and the speed reduction mechanism. More particularly, the present invention relates to an improvement in a reel for automatically stopping the feeding of fishing line from a rotating body. It is.

[0002]

2. Description of the Related Art Conventionally, there is an electric reel constructed as described above, as disclosed in Japanese Patent Application Laid-Open No. 2-150228. In this conventional example, a clutch slide is operated by a sliding operation to enter and disengage a clutch mechanism. An electromagnetic solenoid for urging the moving plate toward the clutch engagement side, providing a clutch switching plate for engaging and holding the clutch sliding plate at the clutch disengaged position, and further operating the clutch switching plate in the disengagement direction; When it is detected that the fishing line has been fed out by a predetermined amount through the cam plate and the cam plate, the engagement of the clutch sliding plate is released by the driving of the electromagnetic solenoid, and the clutch mechanism is turned on (hereinafter, referred to as operation). , Automatic shelf stop).

[0003]

Considering the electric reel constructed as described above, in this conventional reel, in order to make the operation of engaging the clutch mechanism at the time of automatic rack stoppage more secure, the clutch sliding is performed. The biasing force of the spring acting on the moving plate is set to a relatively large value. When the biasing force of the spring acting on the clutch sliding plate is set to a large value, the clutch sliding plate, the clutch switching plate and When the clutch switching plate that engages with the clutch sliding plate is operated in the disengagement direction, the value of the pressure contact force acting on the contact surface of the clutch increases. In order to operate sufficiently, the electromagnetic solenoid also needs to have a relatively large capacity. However, since this type of reel has an electric motor and is relatively heavy, it is necessary to avoid further increase in weight due to the large capacity of the electromagnetic actuator as described above. It is also desired to be small in size. An object of the present invention is not to increase the size of the reel, and at the same time, to suppress weight increase,
The present invention is characterized in that an electric reel capable of reliably stopping an automatic shelf is rationally configured.

[0004]

A feature of the present invention is that an electric motor (6) is provided inside a rotating body (2) for winding a fishing line.
Also, a planetary speed reduction mechanism (P) is arranged, and a handle (4) for winding the fishing line by manual operation and the speed reduction mechanism (P) are linked via a power transmission system, and the reverse rotation operation of the power transmission system is performed. in a state but which has been blocked, the electric motor (6) of the convey to the rotating body by subtracting the driving force (2) the rotating body (2) to drive in the direction that the winding a fishing line with the reduction mechanism (P )
Configure, also operating member an electric reel formed by placing the clutch mechanism (C), said clutch mechanism (C) to the transmission system between the handle (4) and said speed reduction mechanism (P) The on / off operation is performed by the operation of (29), and the operating member (29) is moved to the clutch engagement side by the rotational force of the electric motor (6) in the fishing line winding direction of the rotating body (2). Operating switching mechanism (43)
And the clutch mechanism (C) is used to reduce the speed of the motor.
A stopper (39) for preventing reverse rotation is provided in the transmission system located on the (P) side so as to be switchable between an operating posture and a releasing posture,
Further, an actuator (41) for setting the stopper (39) in the operating posture is provided, and when a predetermined amount of fishing line is measured by a sensor (35) for measuring the amount of fishing line fed from the rotating body (2). in a state set to act posture said stopper (39) by driving the actuator (41), and located at a point comprising a control means (34) for causing the driving of the electric motor (6), The operation and effect are as follows.

[0005]

When the above feature is constituted as shown in FIGS. 1 to 3, for example, when a predetermined amount of fishing line is fed by free rolling of the rotating body 2 in a state where the clutch mechanism C is disengaged. After the stopper 39 is set to the operating position by the driving of the actuator 41, the rotating body 2 rotates in the fishing line winding direction by the driving of the electric motor 6, so that
The switching mechanism 43 operates the operating member 29 to the clutch engagement position, and the free rotation of the rotating body 2 is prevented by the engagement operation of the clutch mechanism C. That is, in this reel, even when the clutch mechanism C is in the disengaged state, the driving rotation of the rotating body 2 in the fishing line winding direction can be performed by changing the posture of the stopper 39, so that the driving force of the electric motor 6 is transmitted through the rotating body 2. The transmission is transmitted to the switching mechanism 43 so that the engagement operation of the clutch mechanism C can be performed. With such a configuration, a strong driving force of the electric motor 6 can be used.
The actuator 41 need only be small enough to have the ability to switch the posture of the stopper 39.

[0006]

As a result, an electric reel capable of suppressing the increase in the size of the reel, suppressing the weight thereof, and reliably stopping the automatic shelves with a strong driving force has been rationally constructed.
