Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved electric reel.

[0002]

2. Description of the Related Art Conventionally, electric reels are rotating bodies (spools).
Equipped with an electric motor inside the reel or outside the reel body, etc., at the time of actual fishing, the electric motor is driven to drive the rotating body in the fishing line winding direction, so that the fishing line can be strongly fed without relying on artificial operation force. It is configured so that it can be wound up.

[0003]

Here, considering the fishing using the electric reel, in this type of fishing, the fishing line is wound onto the spool when the fish is taken in, such as deep sea fishing. Even if the amount of fish is large or the fish is relatively strongly pulled, the fishing line can be strongly wound up without burdening the angler, and fishing can be performed easily.

Further, although a reel of this type has a stronger electric motor for deep seas and is configured to wind a fishing line more strongly, a reel equipped with such a powerful electric motor winds a fishing line. The drive noise of the electric motor is loud when picking up, which is also annoying. In particular, as the load of the electric motor increases, the volume of the driving sound increases, and the sound quality of the driving sound changes to a more annoying one. Therefore, when a large fish is caught on a relatively deep shelf, This driving sound is generated over a long period of time, and an appropriate improvement means is desired.

Therefore, it is conceivable that the electric motor or the entire reel body is covered with a sound absorbing material such as glass fiber to reduce the driving noise. However, when such a sound absorbing material is used, the reel is large. There is an inconvenience that it will lead to

An object of the present invention is to construct an electric reel which can comfortably wind a fishing line by reducing the driving noise of the electric motor without enlarging the reel.

[0007]

The features of the present invention include an electric motor for driving a rotating body for winding fishing line, a sensor for determining a driving sound of the electric motor, and a sound wave generating means for generating a sound wave. And a control device configured to generate a sound wave that interferes with the driving sound from the sound wave generating means based on a signal from the sensor to reduce the driving sound, and its operation and effect. Is as follows.

[0008]

When the above features are constructed as shown in FIGS. 1 and 2, for example, the electric motor 10 is used when the fishing line 4 is wound up.
The drive sound of the drive sound is obtained by the sensor 21, and based on the data of the phase, the amplitude, etc. of the drive sound obtained by the sensor 21, the control device 14 generates the sound wave of the opposite phase with the same wavelength and the same amplitude as the drive sound. An operation of generating the sound by the generating means 22 is performed, and as a result of this operation, the drive sound is canceled by the sound wave of the opposite phase, and as a result, the volume of the drive sound is lowered.

That is, according to the present invention, not only a sound absorbing material or a dedicated member for shutting off sound need not be provided, but also when the wavelength of the driving sound of the electric motor 10 changes, it is possible to respond immediately. Then, the driving sound can be reduced.

[0010]

Therefore, without increasing the size of the reel,
The electric reel was rationally configured to reduce the drive noise of the electric motor and to comfortably wind the fishing line.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 3 and 4, between the left and right side cases 1 and 1, a level winding mechanism including a thread guide tool 3 that is reciprocally driven in the left and right direction by rotation of a screw shaft 2, and

As shown in FIG. 2, in this reel, a planetary type speed reducer 15 for reducing the driving force of the electric motor 10 and transmitting it to the spool is built in the spool 5, and from a handle shaft 16 connected to the handle 7. And a plurality of transmission gears 18 for transmitting the rotational force of the spool 5 to the input gear 2A of the screw shaft 2, and a transmission mechanism for transmitting the driving force of the spool 5 to the spool 5 via a drag mechanism 17 and a clutch mechanism. There is.

The clutch mechanism is composed of a clutch sleeve 19 which can be engaged and disengaged with an engaging portion provided in the output system of the speed reducer 15 by a sliding operation, and the clutch sleeve 19 is operated by the clutch lever 8. It is linked so that it can be switched between the engagement position (clutch engagement position) and the disengagement position (clutch disengagement position) (the operation system is not described in detail).

As shown in FIG. 4, a wheel 20 that meshes with a gear 5A formed on the spool 5 and rotates in cooperation with the spool 5 is provided inside the left side case 1 and the reed switch 13 is provided. Receives the magnetic force of the magnet M attached to the wheel 20, and the spool 5
Is configured to count the amount of rotation of the.

In this reel, the control device 14 obtains map data of the amount of fishing line 4 delivered relative to the amount of rotation of the spool 5 so as to obtain the amount of fishing line 4 delivered from the spool 5 based on the amount of rotation of the spool 5. When the count value is input from the reed switch 13, the control device 14 obtains the amount of the fishing line 4 to be fed out based on the count value and the data and outputs it to the liquid crystal display 11. ..

Further, in this reel, a pair of microphones 21 and 21 (an example of a sensor) for obtaining a driving sound of the electric motor 10 and a speaker 22 (an example of a sound wave generating means) are built in the right side case 1. However, these are used to reduce the drive noise of the electric motor 10.

That is, as shown in FIG. 1, in this control system, the speaker 22 is driven by a signal system for inputting signals from the microphones 21 and 21 to the control device 14 and a signal from the control device 14. A signal system is provided, and when the electric motor 10 is driven, one of the pair of microphones 21 and 21 that is closer to the electric motor,

Based on the transfer characteristics, the drive sound S has a phase opposite to that of the drive sound S.
The sound waves T having the same wavelength and the same amplitude are calculated by a process such as calculation, and the sound waves T are output through the speaker 22 so that the sound waves T and the driving sound S of the electric motor 10 interfere with each other. Then, the control operation is performed so as to reduce the driving sound to a small value.

The control device 14 is also used for the display operation of the liquid crystal display 11, the start and stop of the electric motor 10, and the control of the drive speed, and as described above,
By reducing the drive sound by the interference of sound waves,
Even if a sound absorbing material or the like is not used, the quietness at the time of winding the fishing line is improved and the fishing can be comfortably performed even if the sound quality of the driving sound changes or the sound volume changes during the driving.
