2. Description of the Related Art Conventionally, there is a fishing reel constructed as described above in Japanese Utility Model Laid-Open Publication No. Hei 2-131871. In this conventional example, a fishing reel is built in a spool for the purpose of driving the fishing line in a winding direction. The driving force of the electric motor is used to assist the rotation of the spool in the fishing line payout direction.

[0003]

Here, in consideration of the input of a device in fishing in a boat, after the clutch mechanism is turned off and the input of the device is performed, the fishing line is paid out from the spool by the weight of the device. The device lowers. Further, in the above-mentioned conventional example, by assisting the rotation of the spool with the driving force of the electric motor, a resistance directly acting on the rotation system of the spool like a cast controller, or a system linked to the spool like a level wind mechanism or the like is used. Is offset by the driving force of the electric motor to increase the descent speed of the in-process.

As described above, the electric reel has a favorable surface in which the characteristic of the drive system can be used to increase the descent speed of the work in progress. However, the electric reel is relatively large and heavy. Therefore, in fishing that does not target the deep sea, in a small-sized reel such as a manual type, a technique for assisting the rotation of the spool in the fishing line payout direction as described above to increase the descent speed of the in-process is desired. I have.
In addition, in squid fishing, especially in squid fishing, after the captain detects a group of squid with a fish finder, the captives are thrown in at the same time according to instructions to the captain, but since a false bait is used for the mechanism, It is also known that a large amount of squid is caught on a device that descends the earliest to the depth of the shelf, and for this reason, a technique for quickly lowering the device is required.

An object of the present invention is to operate a means for assisting the rotation of the spool to increase the descent speed of the work in a satisfactory manner.
The fishing reel is made as small as possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 5, a level wind mechanism and a fishing line 4 that reciprocally drive the line guide 3 in the left and right directions by rotating the screw shaft 2 between the left and right side cases 1 and 1 that constitute the reel body. In addition to the arrangement of the spools 5 to be wound, a handle 6, a drag operation tool 7, a clutch lever 8, and a cast controller 9 are provided on the right side case 1 side, and the upper side of the left and right side cases 1, 1 is provided. Thus, a fishing reel used for boat fishing is provided with the control case 10.

A spool shaft 11 that rotates integrally with the spool 5 is supported on left and right side cases 1 and 1, and an engaging portion 11 A formed on the spool shaft 11 and a clutch sleeve 12 that can be disengaged are attached to the spool shaft 11. A handle shaft 13 which is slidably fitted to the outside and which is connected to the handle 6
A drag mechanism 14 is fitted to the outside of the clutch sleeve 12, an output gear 14A of the drag mechanism 14 is engaged with an input gear 12A of the clutch sleeve 12, and a power from an output gear 15 provided on the spool shaft 11 is transmitted to an intermediate gear. A transmission system for transmitting to the input gear 2A of the screw shaft 2 via the shaft 16 is formed.

A clutch mechanism C is constituted by the engaging portion 11A of the spool shaft 11 and the clutch sleeve 12.
The clutch mechanism C is switched between an on state and an off state by operating the clutch lever 8 (an operation system is not described in detail), and the cast controller 9 is brought into contact with the spool shaft 11 by its rotation operation. The braking force acting on the spool 5 can be adjusted by changing the force.

The control case 10 includes a control device 17 comprising a microprocessor, and reed switch type sensors 19, 19 for counting the magnetic action of a plurality of magnets 18 # embedded in the flange of the spool 5. And
Also, the fishing line 4 based on the count signals of the sensors 19, 19
, And a plurality of control switches 21 #.

In this reel, when the clutch mechanism C is disengaged and the device is put into the sea, the rotation speed of the spool 5 is assisted to increase the descent speed of the device, and the spool 5 is operated by operating the handle. When the is driven in the fishing line winding direction, a rotational driving force is applied to the spool 5 to perform a smooth winding operation. The auxiliary driving means includes a ring-shaped permanent member formed on a flange portion of the spool 5. It comprises a magnet (an example of a driven body) 22 and a ring-shaped field coil 23 arranged at a position near the rotation locus of the permanent magnet 22. The field coil 23 receives a signal from the control device 17. Battery 26 built in thumb rest 25 via driven driver 24 (built in control case 10)
The control device 17 controls the rotation of the spool 5 based on feedback signals from the sensors 19, 19 by supplying electric power from the magnetic field coil 23 to generate a rotating magnetic field. The permanent magnet 22 has an N-pole and an S-pole alternately arranged along the inner peripheral surface of the ring portion. A magnetic member 27 made of a magnetic material such as iron is externally fitted on the outer periphery of the permanent magnet 22 to form a magnetic circuit. The field coil 23 is provided with a plurality of coils 23A # in its circumferential direction. The field coil 23 is housed in a doughnut-shaped watertight case 28 and a plate 29 for closing the spool insertion hole. The permanent magnet 2 is externally fitted to the positioning boss 29A projecting from
The air gap with the spool 2 is kept uniform at a small interval, and the axis of the field coil 23 and the axis of the spool shaft 11 are aligned.

In this reel, control is performed as shown in FIG. 6 when a work is put in. In this control, first, a sensor 19,
19, the rotation direction of the spool 5 is determined (# 101 step, # 102 step), the clutch mechanism C is turned off, a work is put in, and the spool 5 rotates in the fishing line payout direction. Is started, the rotation speed is sampled by the sensors 19 and 19, the change in the descent speed of the in-process is obtained, the change characteristic is set, and the elapse of a predetermined time, the feeding of a predetermined amount of fishing line, or the When the descending speed decreases to a predetermined value, the field coil 23 is driven so that the change characteristic is set as a control target and a driving force is applied to the spool 5 in a form in which signals from the sensors 19 and 19 are fed back ( # 103
Step to # 105 step). The reason why the driving force is not applied to the spool 5 at the same time as the loading of the device as described above is that the resistance of water is relatively small in the initial stage of the loading of the device, and the device is descending at a sufficient acceleration. This is because the need for assisting feeding is low, and backlash is likely to occur even when the ship is swaying. In this sampling, the rate of change in the descent speed of the device depends on the configuration of the device, the weight of the weight, etc. Therefore, this is a process for obtaining the rate of change.

The driving force of the auxiliary driving means is set to be weak enough to cause a slip between the field coil 23 and the permanent magnet 22 when the summing is performed. In this feedback control, the driving force is obtained as described above. This assists the rotation of the spool 5 at a target speed corresponding to the depth of the device based on the rate of change of the device lowering speed. In this control, each of the plurality of coils 23A # constituting the field coil 23 is connected to each other as shown in FIG. Are successively energized in the direction indicated by arrow F to generate a rotating magnetic field. Incidentally, the driver 24 includes an element such as a switching transistor.
The direction of energization is switched between forward and reverse so that a driving force is obtained by a suction force and a repulsion force with respect to.

This control is performed by the control switch 21.
Is artificially released by the operation of a predetermined one of
Alternatively, when the device lowers to the depth of the shelf set last time, the power supply to the field coil 23 is stopped to end the control (steps # 106 to # 108). In addition, the depth of the shelf set last time is the depth of the device that caused a hit when the device was previously inserted, or the depth of the device that was maintained for a relatively long time last time, or artificially from the outside. The depth indicates an input value, and the depth is set in a memory or the like of the control device (control operation is not described in detail). In the reel, when the fishing line is wound by operating the handle, the rotation speed of the spool 5 is determined based on the signals from the sensors 19 and 19 (steps # 109 and # 110). The field coil 23 is driven so that a magnetic field is generated in the field coil 23 (steps # 110 and # 111), and control is performed to change the drive following a change in the winding speed of the spool 5. Is configured. In this way, the reel is configured such that whenever the spool 5 rotates, the field coil 23 is always driven to automatically assist the rotation of the spool 5.
