[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric motor having a rotating body for winding a fishing line and driving the rotating body in a winding direction via a winding drive system.
The present invention relates to an electric reel including a clutch mechanism for setting a rotating body to a freely rotatable state by a disengagement operation, and more particularly to a technique for operating a clutch mechanism via an actuator.

[0002]

2. Description of the Related Art Conventionally, a fishing reel constructed as described above is disclosed in Japanese Patent Application Laid-Open No. 63-248328. In this conventional example, a clutch is disengaged from a rotating body. Of the fishing line, and
When it is detected that the fishing line has been fed out by a predetermined amount, the electric motor for winding drive is operated, so that the automatic return type clutch mechanism is engaged and operated. In this conventional example, the clutch mechanism is configured as an occlusion type that transmits power by the engagement of two members, and when the clutch mechanism is engaged, the two members are operated in the engagement direction by the urging force of a spring.

[0003]

Considering a recently marketed electric reel, a recently marketed electric reel repeats the operation of rotating and stopping the spool to obtain a "shake clearance" in the process. There is also a mechanism that gives a "shaky" movement to the in-process by repeating the operation of rotating and stopping the spool. However, if the clutch mechanism is forgotten, the mechanism will move to a level shallower than the shelf. It is also desired to automatically turn off the data. Further, regarding the clutch mechanism, since the above-mentioned reel is configured with an occlusion type clutch mechanism that transmits power by occlusion of two members, when the two members are operated in the occlusion direction (the direction in which the clutch mechanism enters). As described above, although the operation can be performed with a relatively light force such as the biasing force of a spring or the like, when the two members are set in the occluded state, the tension of the fishing line or the electric Since the driving load of the motor acts (strictly speaking, the surface pressure of the contact surface that transmits power in the occlusion portion increases), the operation load in the direction of disengaging (disengaging direction of the clutch mechanism) increases, For example, if an attempt is made to operate a clutch mechanism having this structure with an actuator, a large-sized actuator is required specially, and there is room for improvement. An object of the present invention is to rationally configure an electric reel capable of disengaging a clutch mechanism without providing a specially large actuator.

[0004]

SUMMARY OF THE INVENTION The present invention is characterized in that, as described at the outset, an electric reel having an electric motor for driving a rotating body in a winding direction and a clutch mechanism, A switching mechanism for performing an on / off operation is formed, and the driving force from the electric motor is transmitted to the switching mechanism via an operation drive system formed separately from the winding drive structure, and the clutch mechanism is operated. At least a point of providing an operation mechanism for performing a disengagement operation, and disposing a reverse rotation prevention mechanism of a transmission system linked to the clutch mechanism only when the electric motor is disposed inside the rotating body and the clutch mechanism is engaged. A drive mechanism is provided for driving and rotating the rotating body in the winding direction by the power transmitted from the electric motor as a power point, and the operating mechanism is connected to the clutch mechanism. In an operating state, the driving force of the electric motor is transmitted to the switching mechanism to switch the clutch mechanism by operating the switching position, and a non-operation position in which the driving force is not transmitted to the switching mechanism when the electric motor is driven is configured to be switchable. At the point,
The operation and effect are as follows.

[0005]

When the above features are configured as shown in FIGS. 1 to 10, for example, when the clutch mechanism C is disengaged, the power of the electric motor 13 is transmitted to the switching mechanism A via the operating mechanism A. Accordingly, the clutch mechanism C reaches the disengaged state by the driving force of the electric motor 13. That is, in the present invention, the strong driving force of the electric motor 13 provided on the reel body for driving the rotating body 2 can be used.
Even if the clutch mechanism C is configured to be an occlusal type that transmits power by the occlusal engagement of the two members, when the two members are operated in the occlusal releasing direction (the disengaging direction of the clutch mechanism), the occlusal portion Due to the tension of the fishing line 6, the operation in the direction of releasing the bite can be easily performed even if the contact pressure for transmitting power is large.

[0006]

As a result, an electric reel capable of operating the clutch mechanism without any special large-sized actuator can be rationally constructed.

Next, when the length of the fishing line 6 being unreeled from the spool 2 reaches the value of the shelf (steps # 105 and # 106). In the same manner as described above, the DC motor 35 is driven until the sensor 40 determines that the shifter 26 has reached the ON position (steps # 107 to # 110). Note that the depth at which the automatic shelf stop is performed coincides with the value displayed on the shelf display section 7B.
