DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric motor for winding a handle for winding a rotating body for winding a fishing line, or in a state where the rotation of the handle in a fishing line unwinding direction is prevented. The present invention relates to an improvement in an electric reel including a planetary gear type reduction mechanism that transmits a driving force of a motor to the rotating body and drives the rotating body in a fishing line winding direction.

[0002]

2. Description of the Related Art Conventionally, there is an electric reel constructed as described above in Japanese Utility Model Laid-Open No. 1-94063. In this conventional example, a sun gear is provided on an output shaft of an electric motor. A planet gear that meshes with the sun gear is meshed with an internal gear that is integrally formed on the inner peripheral surface of the spool (rotary body), so that the carrier of the planet gear and the handle are linked. In this reel, as described above, the spool is driven in the fishing line winding direction by driving the electric motor during the winding operation of the handle or in a state where the rotation in the fishing line unwinding direction is prevented. Is configured.

[0003]

Here, consider a reel having a planetary gear type speed reduction mechanism as described above.
In actual fishing with this type of reel, usually, the fishing line is often wound only by driving an electric motor, and in a conventional reel, an operating system of a handle is provided so as to be able to wind with a driving force in this manner. A stopper and the like for preventing reverse rotation are provided. The stopper may be released when the shelving operation is performed during actual fishing, and the electric motor may be driven while the shelving operation is being performed. However, during this shelving operation, the electric motor may be erroneously driven with the stopper set to the released state. In addition to being unable to drive in the winding direction, the handle may be reversed by the power from the electric motor and hit the fisherman's hand, which is dangerous. An object of the present invention is to rationally configure an electric reel that eliminates the inconvenience caused by driving the electric motor in a state where the handlebar is allowed to rotate in the reverse direction as described above.

[0004]

A feature of the present invention is that, in the electric reel having the planetary gear type speed reduction mechanism as described at the beginning, rotation of the handle in the fishing line payout direction is permitted. In addition to the provision of a sensor for detecting, when the sensor detects the rotation allowable state of the steering wheel, it is provided with a driving restraint means for preventing the driving of the electric motor, and the operation and effect are as follows. is there.

[0005]

When the above features are configured as shown in FIGS. 1 to 7, for example, in a state where the stopper 14 is set in the release position and the handlebar 4 is allowed to reverse, the sensor S detects this state and In this state, even if the electric motor 6 is activated by operating the switch 29, the driving restraint means A
Block the supply of current to the electric motor 6 and drive is not performed. That is, in the present invention, even if the angler attempts to drive the electric motor 6 without noticing that the reverse rotation of the handle 4 is permitted by the setting of the stopper 14 or the like, the drive of the electric motor 6 is not performed. No inconvenience such as reversal of 4 occurs.

[0006]

Therefore, even if the electric motor is erroneously driven in a state where the reverse rotation of the steering wheel is permitted by a relatively simple modification including the sensor and the driving restraint means,
The electric reel, which prevents dangers such as the handle hitting the angler's hand, was rationally configured.
