Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric reel, and more particularly, to an electric reel operated by electric power supplied from an external power supply via a power cord.

[0002]

2. Description of the Related Art An electric reel generally includes a reel body mounted on a fishing rod, a spool rotatably mounted on the reel body, and a motor for rotating the spool in a line winding direction. On the upper surface of the reel body, a counter case housing a water depth display unit for displaying the water depth of a device attached to the tip of the fishing line is mounted. A connector for connecting a power cord for supplying electric power from an external power supply to the motor and the water depth display unit is mounted at a rear portion of the reel body. The external power supply is usually arranged on the ship, a crocodile clip for connecting to the external power supply is provided at one end of the power cord, and a plug connectable to the connector part is provided at the other end. I have. A liquid crystal display as a water depth display unit and a control unit having a CPU, a RAM, and the like for controlling the liquid crystal display and also controlling the motor are provided in the counter case. Various operation buttons are also arranged on the counter case. The control unit calculates and displays the water depth of the device from the rotation data of the spool, for example, based on the water depth calculation information stored in the RAM, and sets the motor speed in accordance with the state of the button operation for motor control. ing.

[0003] In this type of electric reel, the power cord is often connected to an external power supply with a crocodile clip, so if the power cord is pulled for any reason,
The power cord may be disconnected from the external power supply. When the power cord is disconnected from the external power supply, power supply to the control unit is cut off, the CPU is reset, and the contents of the RAM are erased. Therefore, even if the power cord is connected again, the water depth calculation information may be reset, and the water depth may not be displayed correctly.

In order to cope with such a situation, there has been provided an apparatus in which a backup power supply such as a capacitor is provided inside the reel. This capacitor is usually provided in the counter case, and has a relatively small capacity for backing up the CPU and the RAM.

[0005]

In the conventional electric reel, since the backup power supply is provided in the counter case having a small space, the capacity of the backup power supply can be suppressed small, and the power consumption due to the consumption of the external power supply can be reduced. It is not possible to cope with a relatively long interruption of power supply such as interruption of supply. Further, if a power supply is provided in the counter case, it is difficult to detachably provide a backup power supply for an electric reel which is often used in a corrosive atmosphere. This is because, when the counter case is opened to replace the power supply, the inside of the counter case is exposed to a corrosive atmosphere, which causes an electrical failure.

Therefore, it is conceivable to mount a capacitor or a battery having a large capacity outside the counter case. However, when a backup power supply having a large capacity is provided outside the counter case, the size of the reel body becomes large, and the size of the reel increases.

An object of the present invention is to make it possible to keep the size of the reel body small even when a backup power supply having a relatively large capacity is mounted on the reel body.

[0008]

An electric reel according to a first aspect of the present invention is a reel operated by electric power supplied from an external power supply via a power cord, and includes a reel body, a connector, a spool, a motor, , A motor drive unit, a control unit, a storage unit, and a backup power supply. The reel body is mounted on a fishing rod. The connector section is provided on the reel body for detachably mounting the power cord. The spool is for winding a fishing line rotatably mounted on a reel body. The motor is for rotating the spool in the line winding direction. The motor driving means is means for driving the motor to rotate by electric power supplied from an external power supply. The control means is a means for operating with electric power supplied from an external power supply and controlling the motor driving means. The storage unit is provided inside or outside the control unit, and is a volatile unit that holds control information required by the control unit. The backup power supply is a power supply that is disposed on the fishing line payout side of the reel body and on the side close to the fishing rod, and supplies power to at least one of the control unit and the storage unit when the supply of power from the external power supply is interrupted. .

In this electric reel, when the power supply from the external power supply is cut off due to disconnection of the power supply cord from the external power supply or disconnection of the power supply cord from the connector portion, the control means is switched from the backup power supply. And power is supplied to the storage means. Thereby, the control means continues the control based on the control information stored in the storage means. This backup power source has a relatively spatial margin at a position on the fishing line payout side of the reel body and on the side approaching the fishing rod, for example, when the level wind mechanism is located in front of the spool, it is located below and in front of the level wind mechanism. Placed in place. Therefore, the size of the reel body can be kept small even if a relatively large capacity backup power supply is mounted on the reel body.

[0010] An electric reel according to a second aspect of the present invention is the electric reel according to the first aspect, wherein the storage means comprises a volatile memory. In this case, even if the power cord is disconnected, power is supplied to the storage unit from the backup power supply, so that the storage contents of the storage unit including a volatile memory such as a DRAM (Dynamic Random Access Memory) are erased. Never be.

An electric reel according to a third aspect of the present invention is the electric reel according to the first or second aspect.
The reel according to claim 1, further comprising a water depth display means which operates with electric power supplied from an external power supply, and displays a water depth of a device mounted on a tip of the fishing line in accordance with an amount of reeling out or winding of the fishing line to the spool. The control means also controls the water depth display means, and the backup power supply supplies power to at least one of the control means, the storage means, and the water depth display means when the supply of power from the external power supply is interrupted. In this case, the reel main body can be kept small even if a backup power supply capable of supplying power to the water depth display means having a large power consumption is mounted on the reel main body.

According to a fourth aspect of the present invention, in the reel of the third aspect, the backup power supply supplies power to all of the control means, the storage means, and the water depth display means when power from the external power supply is cut off. In this case, power is supplied from the backup power supply to all three means,
Even if the power cord is removed, the electric reel can be used as a manually wound dual-bearing reel, and the usability of the electric reel is improved.

[0013] The electric reel according to the fifth aspect includes the electric reels according to the first to third aspects.
Wherein the backup power supply supplies power only to the storage means when power from the external power supply is cut off. In this case, the backup power supply
When the power from the external power supply is cut off, it is only necessary to supply the power to the storage means that consumes relatively little power.
It is only necessary to prepare a backup power supply having a smaller capacity than in the case where power is supplied to all three means, and the reel body can be kept even smaller.

The electric reel according to the sixth aspect of the present invention includes the electric reels according to the first to fifth aspects.
In the reel described in any one of the above, the backup power supply is a capacitor. In this case, since a capacitor that can be stored by electric power supplied from an external power supply is used as a backup power supply, the configuration of the power supply circuit is simplified. In addition, if a capacitor is used, replacement of the backup power supply in a corrosive atmosphere becomes unnecessary, and the corrosion resistance of the electric reel is improved.

[0015] The electric reel according to the seventh aspect of the present invention includes the electric reels according to the first to fifth aspects.
Wherein the backup power supply is a secondary battery. In this case, replacement is not required, and the same effect as that of the capacitor can be obtained. In addition, since the power supply capacity can be made larger than that of the capacitor, the power supply can be backed up for a long time.

The electric reel according to the eighth aspect of the present invention includes the electric reels according to the first to seventh aspects.
The backup power supply is detachably mounted on the reel body. In this case, since the backup power supply is replaceable, it is possible to easily cope with the deterioration of the backup power supply. Since the replacement of the backup power supply is infrequent, it is not necessary to perform the backup power supply in a corrosive atmosphere when fishing is not performed, and the corrosion resistance is hardly affected.

A control unit 20 shown in FIG. 5 is provided inside the counter case 4. The control unit 20 includes a CPU, a storage unit 24, and a RO disposed in the counter case 4.
The microcomputer includes a microcomputer including an M and an I / O interface, and executes various control operations described later according to a control program. A volatile DRAM is used for the storage unit 24, and various control information such as water depth calculation information used by the control unit 20 is stored therein. The control unit 20 includes a liquid crystal display unit 5, a motor on / off switch PB, a speed adjustment switch SK,
Spool sensor 21, buzzer 22, other buttons of operation key unit 6, solenoid for clutch-on (not shown)
And other input / output units including the above.

The control unit 20 includes a motor drive circuit 23 for driving the motor 12 and a charge amount detection circuit 28.
And the backup power supply BP.

The motor 12 is connected to the motor drive circuit 23, and the current supplied to the motor 12 is pulse width modulated by a control signal from the control unit 20 to drive the motor 12 variably. The motor drive circuit 23 is connected to the main body connector 19, and is supplied with, for example, 12 volts of power supplied from an external power supply PS.

A transformer circuit 32 is also connected to the main body connector 19. The transformer circuit 32 transforms, for example, 12 volt power supplied from the external power supply PS to, for example, 3 volt power required by the control unit 20 and the liquid crystal display unit 5. A backup power supply BP is connected to the transformer 32 via a backflow prevention circuit 41. The backflow prevention circuit 41 is formed of, for example, a diode, and has an internal power supply BP.
Is provided in order to prevent the power stored in the inverter from flowing back to the transformer circuit 32 side.

The backup power supply BP is, for example, 0.5
It is composed of a storable capacitor having an electric capacity of about F and has a larger power supply capacity than conventional ones. The backup power supply BP is provided to back up the control unit 20, the liquid crystal display unit 5, and the storage unit 24 when the external power supply PS is unexpectedly disconnected, and the power supply cord 18 is provided.
It is provided for operating the water depth display function when the reel is removed and used as a manually wound reel. As shown in FIG. 4, the backup power supply BP is irremovably mounted on a battery mounting portion 30 provided on the front cover 9. A packing 3 is provided between the backup power supply BP and the power supply mounting section 30.
1 is mounted, and the back side of the power supply mounting portion 30 from the packing mounting portion is watertight. Since the position of the power supply mounting portion 30 is below the opening 9a, it is located below and in front of the level wind mechanism 13, that is, on the fishing line feeding side of the reel body 1 and on the side approaching the fishing rod. This position is
It is a position where there is relatively room in the reel body 1. Therefore, even if a relatively large backup power supply BP is mounted here, the reel body 1 can be kept small.

The charge amount detection circuit 28 is arranged between the backup power supply BP and the control unit 20, detects the charge amount of the backup power supply BP by, for example, a voltage, and outputs a detection signal to the control unit 20. This detection result is displayed on the charge amount display section 5f.

As described above, the backup power supply BP is mounted on the lower front part of the reel unit 1 among the components of the control system, and the remaining components are housed in the counter case 4.

Next, an outline of the control operation will be described.

When fishing is performed using an electric reel controlled as described above, for example, when a fishing rod is mounted on a rod support attached to the rim of a boat and a mechanism is thrown or collected in a standing rod state, The power cord 18 is mounted on the reel. Thus, the power of the external power supply PS is supplied to the control unit 20 and the liquid crystal display unit 5 via the transformer circuit 32, the backflow prevention circuit 41, and the backup power supply BP, and the control unit 2
0 is the initial setting. Also, electric power is supplied to the motor drive circuit 23. As a result, the motor 12 can be rotated by the electric power from the external power supply PS, and the control unit 20
And the liquid crystal display unit 5 operates. The motor 12 is turned on and off by operating the motor on / off switch PB. The speed of the motor 12 (the winding speed of the spool 10) is increased or decreased by operating the speed adjustment switch SK.

When the power cord 18 is disconnected from the reel body 1 or the external power supply PS, the supply of power from the external power supply PS to the electric reel is cut off. As a result, the backup power supply B
The power stored in P is supplied to the control unit 20 and the liquid crystal display unit 5, and is further supplied to the storage unit 24 in the control unit 20. For this reason, since the content stored in the storage unit 24 is retained, the control unit 20 continues the control, and the liquid crystal display unit 5 also continues the display. Therefore, even if the power cord 18 is accidentally disconnected, control and display are continued. Until the backup power supply BP is exhausted, the power cord 18 can be consciously detached and used as a manually wound reel when a fish is hooked on the device and the fish are put together. The charge amount of the backup power supply BP can be confirmed by looking at the charge amount display section 5f.
The power of the backup power supply BP is supplied to the backflow prevention circuit 41.
Therefore, the electric power is not supplied to the transformer circuit 32 side, and the motor 12 cannot be driven by this electric power.

In this case, since the backup power supply BP is provided at a relatively lower space in the front lower part of the reel unit 1, even if the relatively large-capacity backup power supply BP is provided on the reel unit 1, 1 is difficult to enlarge.

[Other Embodiments] (a) In the above embodiment, power was supplied from the backup power supply BP to the control unit 20 and the liquid crystal display unit 5.
As shown in (1), power may be supplied only to the storage unit 24. In FIG. 6, for example, a storage unit 24 composed of a DRAM is provided outside the control unit 20, and inputs and outputs control information to and from the control unit 20. Such a control unit 20
When power is supplied only to the storage unit 24 provided outside the unit, the unit cannot be used as a manually wound reel, but the control information is protected even if the power cord 18 is accidentally disconnected. Further, since the power consumption is smaller than that of the above embodiment, the capacity of the backup power supply BP can be small, and the reel body can be further downsized. Further, in the case of the same electric capacity, power can be supplied for a long time.

(B) In the above embodiment, the backup power supply BP is configured to be charged by supplying power from the external power supply PS. However, as shown in FIG. 7, a solar cell 42 for charging the backup power supply BP is charged. Charging device 4 having
3 may be mounted on the counter case 4, for example.
In this case, even if power is not supplied from the external power supply PS to the backup power supply BP, power is supplied from the charging device 43 to the backup power supply BP as long as light is irradiated. For this reason, the backup power supply BP is less likely to be consumed, and the liquid crystal display unit 5 can be displayed for a long time even if the power cord 18 is detached and used as a manually wound reel.

(C) In the above embodiment, a capacitor is used for the backup power supply BP.
For P, a secondary battery such as a nickel cadmium battery or an alkaline ion battery may be used. Further, a primary battery such as a manganese battery or an alkaline manganese battery may be used. In this case, the backup power supply BP may be configured to be replaceable. When the backup power supply BP is made replaceable, the waterproof performance is slightly deteriorated as compared with the case where the backup power supply BP is not replaceable. However, when the backup power supply BP is deteriorated, it can be easily dealt with.

[0044]

In the electric reel according to the present invention, the backup power supply is located on the fishing line payout side of the reel body and on the side approaching the fishing rod, and is arranged in a place where there is a relatively large space. Therefore, the size of the reel body can be kept small even if a relatively large capacity backup power supply is mounted on the reel body.
