Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an electric motor that drives a rotating body for winding a fishing line, and a microcontroller that controls the electric power supplied to the electric motor through a switching means. The present invention relates to a fishing reel including a processor.

[Conventional technology]

A fishing reel configured as described above is usually called an electric reel, and in conventional electric reels, when controlling the electric motor, the switching means is controlled by a signal output from a microprocessor. Adjust the amount of power supplied to the

Incidentally, a switching transistor such as an FET is conventionally used as the switching means.

[Problem to be solved by the invention]

Here, considering the operation when controlling the electric motor with a conventional electric reel, since the electric motor used in the electric reel has a structure that allows a relatively large current to flow, the switching means is turned on and off. When you let
A surge voltage is always generated, and this surge voltage generates high-frequency noise, which acts on the microprocessor via the line that controls the switching means, and may cause malfunctions such as causing the microprocessor to run out of control.

Furthermore, if a malfunction occurs in the microprocessor, it is difficult to even know from the outside that the malfunction has occurred. For example, if a malfunction occurs while the reel is winding the device, it is difficult to stop the winding. This may not be possible and may lead to inconveniences such as damage to the fishing rod.

SUMMARY OF THE INVENTION An object of the present invention is to rationally configure a fishing reel in which the microprocessor is less likely to malfunction even when the electric motor is frequently controlled to turn on and off.

[Means to solve the problem]

The features of the present invention are as described above (in a fishing reel comprising an electric motor, a switching means, and a microprocessor, the system between the switching means and the microprocessor or the switching means itself is non-conductive). The function and effect are as follows.

[Function] When the above characteristics are configured as shown in FIGS. 1 and 2, for example, when a signal is output from the microprocessor (19) to control the electric motor (M), this signal is transmitted to the coupler ( 17) to operate the switching means (24), which actuates the electric motor (M
) from the power source (25).

The specific electric circuit of this configuration is shown in FIG. 2 (this circuit shows the principle to make the operation easier to understand), and the present invention also uses a switching system as shown in FIG. It is also possible for the means (24) itself to be constituted by a coupler (17); in either configuration, the electric motor (
The power system of the electric motor (M) and the control system of the microprocessor (19) are in a non-conductive state, that is, in an isolated state, so even if a large surge voltage occurs in the power system of the electric motor (M), the microprocessor (19) 19) No noise is applied to the control line.

〔Effect of the invention〕

Therefore, a fishing reel has been rationally constructed in which the microprocessor is less likely to malfunction even when the electric motor is frequently turned on and off.
