Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric fishing reel, and more particularly to an electric fishing reel in which the whole reel is reduced in size.

[0002]

2. Description of the Related Art In general, when fishing a deep-sea fish layer, such as boat fishing, an electric fishing reel is widely used. This electric reel for fishing (hereinafter referred to as "electric reel") operates a spool motor mounted between the side plates of the reel body or in a spool by power supply from a battery to perform a winding operation of a fishing line. .

In recent years, in order to improve fishing results, in many electric reels, the output of the spool motor is changed from an OFF state to a maximum value (0 to 100%) as disclosed in Japanese Patent Application Laid-Open No. 5-168380. The fishing line can be adjusted continuously, and the line length of the fishing line (the amount of unreeling from the spool) can be measured and displayed. Stop device that automatically stops the spool motor when it is wound up to the ship's side, and stops the take-up, and an automatic shaking device that automatically shook the device according to the operation pattern stored in advance. Various devices are incorporated.

[0004]

Conventionally, in an electric reel equipped with these devices, a motor drive control circuit for controlling the driving of a spool motor has a control case provided between side plates on the upper portion of the reel body. Is housed inside. However, for example, as a means for adjusting the output of the spool motor, a switching power supply circuit equipped with a power mos has conventionally been incorporated in a motor drive control circuit. 8
In order to reach a high temperature of 0 ° C., a switching power supply circuit equipped with a power mos is attached to a radiator or the like.

For this reason, when the motor drive control circuit having such a switching power supply circuit is housed in the control case, the control case itself becomes large, and as a result, the entire reel becomes large, which hinders the operability of fishing. There was a risk of doing so. In addition, since the spool motor generates heat as it is driven, and the power moss also generates heat as described above, if the motor drive control circuit having the power mos is disposed in a control case near the spool motor, the power mos The heat dissipation is poor, and the resin control case is deformed by the heat generated by the power moss, and the temperature difference between the inside of the control case and the outside air causes
There is a possibility that the display portion of the yarn length measurement value provided on the operation panel of the control case becomes cloudy.

Japanese Utility Model Laid-Open No. 5-91344 and Japanese Utility Model Laid-Open No. 63-181269 disclose electric reels in which a booster, a breaker, and the like are mounted on a power supply cord of the electric reel. Even in the example, since the motor drive control circuit is mounted in the control case, the above-mentioned problem could not be solved.
In addition, since these electric reels can be used with a conventional power supply cord without a booster or a breaker, when a large number of electric reels and power supply cords are used on a ship, the conventional power supply cord can be used. There was also a risk that useless troubles would occur when used and confused with codes.

The present invention has been devised in view of the above circumstances, and provides an electric reel in which the entire reel is reduced in size by improving a mounting position of a motor drive control circuit for controlling the drive of a spool motor. The purpose is to:

It is characterized by.

The invention according to claim 2 is based on claim 1.
In the electric reel described above, the connection line is a power supply cord connected to the reel body.

According to the present invention, the motor drive control circuit conventionally housed in the control case is arranged outside the reel body, so that the control case and, consequently, the whole reel can be miniaturized. In addition, since the motor drive control circuit is disposed outside the reel body away from the spool motor, the heat of the motor drive control circuit can be radiated well without being affected by the heat of the spool motor. .
