A spool SP is rotatably supported on this shaft SF via bearings 19, 19'.

Note that the above-mentioned spool SP is provided so as to be slidable in the axial direction of the shaft SF.

The above-mentioned first transmission mechanism G1 is the above-mentioned spool SP.
is driven in the winding direction, and the first motor M1 is its driving source.

The driving force of the first motor M1 in the winding direction is input to the input gear 2 via the output gear 5 and the reduction gear 6, and the ratchet 7 engages and disengages on the back side of the input gear 2.
allows rotation in the winding direction and locks rotation in the feeding direction.

The input gear 2 described above is rotatably supported by bearings 1, 1 relative to the shaft SF and the housing 17, and a friction plate 4 to which a lining 3 is fixed is integrally attached to the inner end of the input gear 2. There is.

By strongly abutting the opposing side surfaces of the spool SP, the friction plate 4 described above transmits the driving force in the winding direction, and in the feeding direction, the braking applied by the ratchet 7 is applied to the spool SP. .

Of course, when the opposing side surface of the spool SP separates from the friction plate 4, the above-mentioned driving force and braking are not transmitted.

The washers 21, 21', which are the axial center portion of the spool SP mentioned above and are configured on the left side in the figure, and the spring 20 inserted therein are arranged in a direction that separates the opposing sides of the friction plate 4 and the spool SP. It acts on

And the washer 24 connects the spool SP to the friction plate 4.
Spring 2
5 is set to have greater elasticity than the aforementioned spring 20, and when this spring 25 is strongly compressed,
Due to its elasticity, the spool SP is connected to the other spring 2.
When the spring 25 is slid toward the friction plate 4 side against the elasticity of 0 and the compression of the spring 25 is released,
The spool SP is separated from the friction plate 4 by the elasticity of the other spring 20.

A keyway 26 is engraved in the axial direction on the right side circumferential surface of the shaft SF described above in the drawing.

The first cam 16, which has a center hole 16a that fits into the key groove 26 and is prevented from rotating, is a shaft.
The first cam 16 is slidably inserted in the axial direction of the SF, and a cam-shaped surface is formed on the outer surface of the first cam 16 (see 2e).

Also, the second cam 15 facing this is (second d
(see figure), is inserted into the shaft SF so as to be rotatable and slidable in the axial direction, and forms a cam-shaped surface on its inner surface. When the mutual peaks of are in contact, the mutual cams 16 and 15 slide in the direction of separation,
Further, when the second cam 15 is rotated and the troughs of the cam-shaped surfaces are in contact with each other, the mutual cams 16, 15
slides in the approaching direction, and in this embodiment the second cam 1
5 is rotated in the direction of arrow b in Fig. 2d, the first
The cam 16 slides to the left in Fig. 1, compresses the spring 25, and puts the spool SP into a power transmission state, and the second cam 15 is reversed in the direction of arrow a in Fig. 2d to return to its original state. When returned, the first cam 16
slides to the right in FIG. 1, and the transmission state is released.

A spline 15b is carved on the outer end side of the second cam 15, and the sleeve 14 inserted into the shaft SF meshes with the spline 15b and rotates integrally. The lever 27 is integrally connected.

That is, by operating this lever 27 back and forth, the second cam 15 is rotated in the forward and reverse directions.
This rotation causes the first cam 16 to slide left and right.

A drag 30 is provided at the right end in the figure of the shaft SF described above so that it can be screwed back and forth via a spring 28 and a washer 29. By rotating this drag 30 in forward and reverse directions, the washer 29, sleeve 14, and cam 15 are moved forward and backward. , 16 to adjust the drag pitch and arbitrarily finely adjust the friction pressure between the spool SP and the friction plate 4.

Furthermore, the third cam 12 and the fourth cam 13 are inserted through the smooth portion 15a of the second cam 15 so as to be relatively movable (see FIGS. 2a and 2b).

A tooth row 12a is partially engraved on the outer peripheral surface of the third cam 12, and the other part is cut out to form a regulating piece 17a formed in the insertion portion of the housing 17.
is engaged, and the rotation range of the third cam 12 is restricted.

Moreover, power is transmitted to the above-mentioned tooth row 12a from a second transmission mechanism G2, which will be described later.

A cam-shaped surface is formed on its outer surface.

The fourth cam 13 has a protrusion 13a on its outer peripheral surface.
The protrusion 13a engages with an engaging portion 17b formed in the insertion portion of the housing 17 to prevent rotation, and forms a cam-shaped surface on the inner surface.

When the above-mentioned third and fourth cams 12 and 13 are in contact with each other and the peaks of their cam-shaped surfaces are in contact, the mutual cams 12 and 13 slide in the direction of separation, and When the three cams 12 are rotated and the troughs of the cam-shaped surfaces are in contact with each other, the mutual cams 12 are rotated.
2 and 13 slide toward each other, and in this embodiment, when the third cam 12 rotates in the direction of arrow a in FIG. 3, the cam 12 slides to the right and moves in the direction of arrow b in FIG.
The cam 12 is provided so that when the third cam is rotated in the direction, the cam 12 slides left and right.

The above-mentioned second method transmits forward and reverse driving force to the tooth row 12a of the third cam 12 to perform forward and reverse operations.
It is a transmission mechanism G2, and the second motor M2 is its driving source.

The forward and reverse driving force of the second motor M2 is transmitted to the third cam 1 through the output gear 8 and the intermediate gears 9 and 11.
A lining 10 is fixed to the inner surface of the intermediate gear 11 and is in contact with the other intermediate gear 9, and a lining 3 is attached to the outer side of the intermediate gear 11.
1. A disc spring 32 and an adjustment nut 33 are provided,
The intermediate gear 11 is urged toward the other intermediate gear 9,
This biasing force is adjusted by adjusting the screwing position of the adjustment nut 33.

That is, the intermediate gear 11 constitutes a friction clutch and is provided so as to slip when the third cam 12 comes into contact with the protrusion 17a at the end of rotation and becomes overloaded.

The aforementioned control panel CP is connected to the second motor M2 at terminals A and B, to the first motor M1 at terminals C and D, and to the sensor 36 at terminals E and F.

The above-mentioned sensor 36 is provided on the housing 17 side facing the outer periphery of the flange of the spool SP, and a detection piece 35 is fixed to the flange of the spool SP, and as the spool SP rotates, the detection piece 35 detects the sensor 36. By passing, the sensor 36 detects this and outputs a signal.

In addition, the control panel CP described above has an electronic counter built therein, and counts the detection signal from the sensor 36 described above to measure the winding amount of the spool SP.Furthermore, when the spool SP is fed out, the above-mentioned counted value is calculated. It has a function to control the second motor M2 to stop when the same amount is fed out, and also to turn off the first motor M1,
ON control, and ON control of the second motor M2 is performed.

The operation of the reel configured in this way will be explained.

First, push the lever 27 all the way toward you as shown in Figure 1. In FIG. 2d, the second cam 15 is rotated in the direction of arrow a, and the contact with the first cam 16 becomes a trough of the cam shape, so that the first cam 16 can slide to the right. The spring 25 is released, and the elasticity of the other spring 20 moves the spool SP to the right in FIG. 1, and the friction plate 4 and the spool SP are separated, and the spool SP becomes free.

If you drop the fishing line in this state, the weight of the tackle will cause the fishing line to pay out.

When the device reaches the desired water depth, the lever 27
, as shown in Figure 1, tilt it all the way forward. 2nd d
In the figure, the second cam 15 is rotated in the direction of arrow b,
The contact with the first cam 16 forms a cam-shaped peak, and the spring 25 receives a force in the compression direction, and the elasticity of the spring 25 causes the spool SP to contact the friction plate 4.

When the first motor M1 is in a stopped state, the friction plate 4 is locked in the payout direction by the action of the ratchet 7, so the spool SP that comes into contact with it is stopped, and the payout of the fishing line is stopped.

In this state, if a fish hooks and you try to fry the bait,
Turn on the switch of the first motor M1 on the control panel CP to drive the motor M1 in the winding direction.

This driving force rotates the friction plate 4 in the winding direction via the first transmission mechanism G1, so the spool SP
are also rotated in the same direction, allowing the fishing line to be wound up.

Also, depending on the pull of the fish, the lever 27 and the drag 3
0 in the forward and reverse directions, the friction pressure between the spool SP and the friction plate 4 can be arbitrarily and finely adjusted, and the winding can be controlled.

Further, when the spool SP is rotating in the winding direction, the winding state is detected by the sensor 36, and the winding amount is measured on the control panel CP side.

Then, when a fish is caught, the first motor M1 is turned off while the lever 27 remains in the same position, and the fish is caught. At this time, the reading (counting) of the winding amount (water depth) by the sensor 36 ends.

Note that the spool SP is in a state in which it is in contact with the friction plate 4 and is braked, so that it does not rotate.

Next, when dropping the fishing line again, lever 27
3, the second motor M2 is turned on to the forward rotation side, and this driving force rotates the third cam 12 in the direction of arrow a in FIG. 3 via the second transmission mechanism G2.

When the cam-shaped surfaces of the third cam 12 and the fourth cam 13 come into contact with each other at the troughs, the third cam 12 becomes able to slide to the right in FIG. 1, and the spring 25 is released.
The elasticity of the other spring 20 separates the friction plate 4 from the spool SP, and the spool SP becomes free.

Furthermore, when the rotation of the third cam 12 is restricted by the restriction piece 17a, the second motor M2 is also controlled to stop at the same time.
When the second motor M2 is rotating even when the second motor M2 is regulated, a slip occurs between the intermediate gears 9 and 11.
Overloads are avoided.

Furthermore, as mentioned above, when the spool SP becomes free, it becomes possible to drop the device.

Also, when the device is dropped, the spool SP rotates in the feeding direction, so the amount of feeding is measured by the sensor 3.
It is detected at 6 and counted on the control panel CP side.

When this count value becomes the same as the above-mentioned winding amount, the second motor M2 is reversely rotated, and the third cam 1
2 is rotated in the direction of arrow b in FIG.

When the third cam 12 and the fourth cam 13 come into contact with the peaks of the cam-shaped surfaces, the third cam 12 slides to the left in FIG. 1, so the spring 25 applies pressure in the compression direction. Then, the spool SP is brought into contact with the friction plate 4 to stop the spool SP, and the fishing line is let out and dropped to the same water depth position as the previous time.

Note that when the reverse rotation of the third cam 12 is restricted by the restriction piece 17a, the reverse rotation of the second motor M2 is stopped, but if an overload occurs at this time, the intermediate gears 9,
The slippage at 11 is similar to the case of forward rotation described above.

As described above, according to this embodiment, it is possible to perform the next loading of a device at the same water depth position as the previous time.

In the configuration of this invention, the first cam mechanism includes the first and second cams 1 of the embodiment.
6 and 15, the second cam mechanism corresponds to the third and fourth cams 12 and 13, and the control means corresponds to the control panel CP, but this invention has the configuration of the embodiment. It is not limited to only.
