Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a control mechanism for controlling an electric device provided on a fishing reel inside a sealed case, and A switching system for issuing a desired operation signal by means of a permanent magnet that moves integrally with the operating tool outside the case, and an internal part of the case for determining the position of the operating tool based on the change in magnetic flux from the permanent magnet. TECHNICAL FIELD The present invention relates to a fishing reel control device including a magnetic sensing means arranged in the above, and more particularly, to a technique for improving the detection accuracy of a set position of an operating tool.

[Conventional technology]

As a conventional fishing reel, taking an example of a so-called electric reel in which the spool is wound by an electric motor, there is an electric reel of this type in which the drive speed of the electric motor can be changed in multiple stages. For example, when the drive speed of the electric motor is switched in three stages according to the set position of the operation tool, the operation tool, the permanent magnet, and the magnetic sensing means are arranged in the ninth position in this type of reel switching system. It is represented as shown.

That is, in this electric reel, a board (8) having a microprocessor or the like as a control mechanism for controlling the driving speed of an electric motor (not shown) is housed inside the case (6), and the board (8) ) Are provided with two Hall elements (9a), (9b), etc. as magnetic sensing means at the side position, and the case (6) has a permanent structure that moves integrally with the operating tool (11) outside the case (6). A magnet (12) is provided.

And with this structure, two Hall elements (9
Since the three setting positions of the operation tool (11) are detected by a) and (9b), the magnetic flux acting on the upper Hall element (9a) shown in FIG. If the magnetic flux acting on 9b) is less than a certain value, set the drive speed of the electric motor to high speed mode and set the Hall element (9b) on the lower side.
If the magnetic flux acting on the Hall element (9a) is above a certain value and the magnetic flux acting on the upper Hall element (9a) is below a certain value, the drive speed of the electric motor is set to the low speed mode, and any element (9a), ( Both magnetic fluxes acting on 9b) are below a certain value,
Alternatively, if the driving speed of the electric motor is set to the medium speed mode when the value is equal to or more than a certain value, each hall element (9a),
A system for making a logical decision based on the signal from (9b) is configured.

[Problems to be solved by the device]

Here, considering a switching system configured as shown in FIG. 9, in this configuration, a hall element or the like is provided inside a hermetically sealed case from the viewpoint of preventing intrusion of seawater or the like into the control mechanism. Although the switching system is configured in a non-contact type, in the case where the magnetic sensing means such as the Hall element is arranged inside the case as described above, in the state where the magnetic sensing means and the permanent magnet are closest to each other, It is difficult to reduce the relative distance. For example, if an error occurs in the set position of the operation tool due to long-term use, even a slight error may cause erroneous detection.

The reason why the expansion of the relative distance between the magnet sensing means and the permanent magnet leads to erroneous detection in this way is that the magnetic force line generated in the permanent magnet (12) as shown in FIG. Hall elements (9a), (9b) are used as magnetic sensing means due to the physical property that they are formed in a loop shape from one magnetic pole toward the other magnetic pole, and the lines of magnetic force repel each other.
This is because the Hall elements (9a) and (9b) can be affected by magnetism even if the distance between them and the permanent magnet (12) is slightly large.
If it is attempted to reliably detect the presence of the permanent magnet (12) at the intermediate position between a) and (9b), the Hall element (9a),
There is room for improvement because it takes time and effort for adjustment, such as the need to precisely set the threshold value of the comparator to which the output voltage from (9b) is input.

Therefore, it is conceivable to increase the distance between the magnetic sensing means, but if the distance is increased in this way, the operation stroke of the operation tool becomes large when trying to form a large number of setting positions of the operation tool. It will be too much, and there are difficult aspects to realize.

As described above, the object of the present invention is to provide a magnetic sensing means such as a Hall element arranged in the case as described above, by a rational improvement of a switching system configured to detect a change in magnetic flux due to a position change of a permanent magnet. The reason is to reasonably configure a control device that surely performs a desired switching operation.

[Means for solving the problem]

As described above, the feature of the present invention is that the control means of the electric equipment is housed in the sealed case, the permanent magnet that moves integrally with the operation tool is arranged outside the case, and the magnetic sensing means is provided inside the case. In the fishing reel control device arranged, two types of magnetic sensing elements having different sensing characteristics with respect to the direction of the magnetic flux are used as the magnetic sensing means, and the two different types of magnetic sensing elements are alternately arranged at predetermined intervals. Placed, or
The operation direction of the operation tool is set so as to follow the arrangement direction of the magnetic sensing element, and a plurality of adjacent operation devices are arranged so as to emit magnetic flux of opposite polarities at an interval equal to the predetermined interval with respect to the operation tool. The permanent magnet is included, and its operation and effect are as follows.

[Action]

As described above, the magnetic sensing means is composed of two types of Hall elements that output voltages in opposite directions with respect to magnetic flux in the same direction. The one that generates a voltage is called an N Hall element, and the one that generates a positive voltage with respect to the S pole is called an S Hall element), and the comrades adjacent to the operating tool emit magnetic flux of opposite polarity. In addition, a plurality of permanent magnets are included in the permanent magnet (here, in order to facilitate understanding, a permanent magnet whose N pole can be opposed to each sensing element by operating the operation tool is an N permanent magnet, and A permanent magnet whose poles can face each other is referred to as an S permanent magnet), and an operating tool is N
If the permanent magnet and N Hall element are set to face each other, N
When a predetermined positive voltage is applied from the Hall element, and when the operating tool is set to a position where the N permanent magnet and the S Hall element face each other and the S permanent magnet and the N Hall element face each other, a predetermined negative voltage is applied from each Hall element. Is set to a position where the S permanent magnet and the S hall element face each other, a predetermined positive voltage is output from the S hall element. Further, when the operation tool is set at a position where the S hall element or the N hall element is separated from the permanent magnet, zero or a voltage close to zero is output from each hall element. In order to logically judge these output voltages, for example, it is common sense in a digital circuit, but a positive voltage higher than an appropriate threshold level is a High level value, and a voltage lower than that is a high level value. It should be a low level value.

In other words, in the present invention, two kinds of magnetic sensing elements having different sensing characteristics are arranged next to each other, so that when one type of magnetic sensing element reaches the detection state, the one type of magnetic sensing element is acted on. Even if the magnetism of the permanent magnets to be operated also acts on the magnetic sensing means of the other type, the adjacent magnetic sensing means of the other type has the same polarity as the signal detected by the magnetic sensing element of the one type. Will output the opposite detection signal (that is, have a negative value), and this detection signal of the opposite polarity will be processed by cutting below the appropriate signal level.
This means that the detection signal for the magnetic flux has not been generated.

By the way, the outline of the Hall element is that when a magnetic flux acts on the element while a voltage is applied between the supply voltage terminals, a voltage is generated between the output terminals and the direction of the magnetic flux is reversed. , The polarity of the output voltage is also reversed, so to make the sensing characteristics different for the direction of the magnetic flux as in the present invention, simply use the element in the reverse direction, that is, in the inverted position. I'm done.

[Effect of device]

Therefore, by a relatively simple modification of using two types of magnetic sensing means having different characteristics, erroneous detection can be suppressed and a desired switching can be performed with high accuracy even if the distance between the magnetic sensing means is small. The control device that ensures the operation was configured.
