DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device,
The present invention relates to a power supply device for a fishing reel for supplying electric power to an operation unit including a display unit for displaying a water depth provided on a fishing reel and a control unit for controlling the operation unit.

[0002]

2. Description of the Related Art There is known a fishing reel such as a dual-bearing reel having a water depth display portion formed of, for example, a liquid crystal display for displaying a water depth of a tackle. A fishing reel having this type of water depth display section is provided with, for example, a control section including a microcomputer. The control section measures the payout length or take-up length of the fishing line from the spool, and measures the length. The water depth of the device is displayed accordingly.

[0003] Power is supplied to the water depth display section and the control section from an internal power supply such as a dry battery or a button battery mounted on the reel body, and power is supplied / cut off by a power supply provided on the reel body. This is performed by turning on and off the operation switch. Normally, the power supply operation switch does not directly supply and cut off the power from the internal power supply to the control unit and the water depth display unit, but supplies and cuts off the power indirectly.

Specifically, power from an internal power supply is supplied and cut off by turning on and off a power supply interrupting circuit having a switching transistor, and the power supply interrupting circuit is controlled on and off by a power supply control circuit. The power supply control circuit monitors the state of the power supply operation switch. When the power supply operation switch is turned on, the power supply intermittent circuit is turned on to supply the power from the internal power supply to the water depth display and control unit, and when the power supply operation switch is turned off, the power supply intermittent circuit is turned off. To shut off the supply of power from the internal power supply. This power supply control circuit is also supplied with power from an internal power supply.

[0005] If the power is indirectly supplied and cut off by the power supply operation switch, the size of the switch can be reduced and an auto-off mode for saving power can be easily handled.

[0006]

In the above-mentioned conventional configuration,
Since power is supplied to the power supply control circuit from the internal power supply, the power of the internal power supply is consumed even when the power supply operation switch is turned off. For this reason, when a long time elapses, the internal power supply may be consumed even though the power supply operation switch is not turned on, and the water depth display unit and the control unit may not be able to operate.

An object of the present invention is to suppress power consumption of a reel control power supply when a power supply operation switch is turned off.

<Control Operation of Power Supply Control Circuit> In the dual-bearing reel configured as described above, when the solar cell 34 generates electric power, the electromotive force is boosted to about 3 volts by the booster circuit 35, And stored in the capacitor 37. The power stored in the capacitor 37 is supplied to a power supply control circuit 38. When power is supplied to the power control circuit 38, the power control circuit 38 performs a power control operation.

The outline of the power control operation will be described below.

In the power supply control circuit 38, when the switch 6a, which is a power supply operation switch, is operated, the power supply intermittent circuit 39 is operated.
To control the power from the primary battery 21 to the control unit 3
0 and supply / cut off to the display unit 5. Further, if the reel does not operate for a predetermined time in a state where power is supplied, the control unit 3
0 and a sleep mode in which the supply of power to the display unit 5 is temporarily stopped, and the power supply interrupting circuit 30 is turned off to cut off the supply of power. At this time, the switch 6a is kept on, and the control unit 30 stores the control state in the storage unit 33 formed of a nonvolatile memory. Thus, when the sleep mode is canceled, the previous control state can be returned. In sleep mode (switch 6
a is on and the power is cut off), the spool 10
When the rotation starts or when the other switches 6b and 6c are operated, the sleep mode is canceled and the power supply is restarted.

Next, a specific control operation will be described with reference to FIG.

When power is supplied from the solar cell 34 via the capacitor 37, initialization is performed in step S2 in FIG. In this initial setting, various flags and various control variables are reset. In step S4, it is determined whether or not the spool 10 has started rotating based on the output of the spool sensor 32. This determination is used to determine whether to release the sleep mode. In step S6, it is determined whether the timer T1 is on. The timer T1 is a timer for determining whether or not the reel operation (specifically, rotation of the spool 10) has been performed for a predetermined time or longer, and is used for determining whether or not to enter the sleep mode. You. In step S8, the switch 6
It is determined whether or not a is pressed. This switch 6a
As described above, the power switch is a power operation switch. When the power switch is turned on, the power of the primary battery 21 is normally supplied to the control unit 30 and the display unit 5. In step S10, it is determined whether any of the other switches 6b and 6c has been pressed. This determination is also used to determine whether to release the sleep mode. In step S12, the timer T
It is determined whether or not 1 has exceeded a predetermined time TS. This determination is used to determine whether to enter the sleep mode.

When it is determined that the spool 10 has started to rotate, the process proceeds from step S4 to step S14. In step S14, it is determined whether or not a flag SW indicating whether or not the switch 6a is on is set to "1" (on). If the flag SW is set to "1", the process proceeds to step S16, and the power
It is determined whether or not the flag PW indicating whether or not is turned on is reset to “0” (off state). From these two determinations, it can be determined whether or not the apparatus is in the sleep mode. When in sleep mode (SW =
1, when PW = 0), the process proceeds to step S18,
The flag PW is set to "1". As a result, the power supply intermittent circuit 39 is turned on, and the supply of power from the primary battery 21 is restarted.

If it is determined that the switch 6a has been pressed, the process moves from step S8 to step S22. Step S
At 22, it is determined whether or not the flag SW is set to "1". That is, the switch 6a is turned on (SW
= 1) is determined. When the switch 6a is off (when SW = 0), the process proceeds to step S24,
The flag SW is set to "1" to turn on the switch 6a. In step S26, the flag PW is set to "1". Accordingly, the power supply control circuit 38 controls the power supply intermittent circuit 39 to be in the ON state, and the power from the primary battery 21 is supplied to the display unit 5 and the control unit 30.

When the switch 6a is on (SW = 1)
), The process proceeds from step S22 to step S28, where the flag SW is reset to “0” and the switch 6a
To the off state. In step S30, the flag PW is reset to "0". As a result, the power supply control circuit 38 controls the power supply intermittent circuit 39 to be turned off, and the power from the primary battery 21 is cut off.

When the other switches 6b and 6c are pressed, the process moves from step S10 to step S32. In steps S32 to S36, the sleep mode release processing is executed in the same manner as in steps S14 to S18. That is, in step S32, it is determined whether or not the flag SW has been set to "1", and in step S34, it is determined whether or not the flag PW has been reset to "0". In step S36, the flag PW is set to "1" to cancel the sleep mode.

When the timer T1 exceeds the predetermined time TS, the process proceeds from step S12 to step S38. Timer T
If 1 exceeds a predetermined time TS (for example, 1 hour), a determination is made to enter the sleep mode. In step S38, it is determined whether or not the flag SW is set to "1" after turning off the timer T1, that is, whether or not the switch 6a is already on. If the switch 6a is in the off state, it is not necessary to enter the sleep mode because the power has not been turned on yet. When the switch 6a is on, the process proceeds to step S40. In step S40,
It is determined whether flag PW is set to "1". That is, it is determined whether the power is on.
When the switch 6a is on and the power is not turned on (when SW = 1 and PW = 0), it is determined that the sleep mode has already been entered, so there is no need to enter the sleep mode. If the power has been turned on, the process proceeds to step S42, and the flag PW is reset to "0". As a result, the power intermittent circuit 39 is turned off, the power is cut off, and the apparatus enters a sleep mode. At this time, a signal to that effect is output from the power supply control circuit 38 to the control unit 30. The control unit 30 stores the control state at that time in the storage unit 33, and outputs a signal indicating the completion to the power supply control circuit 38. . The power supply control circuit 38 waits for the signal to turn off the power supply intermittent circuit 39.

<General Reel Operation> To perform fishing, the switch 6a is pressed to turn on the power. The details of this control are as described above. Subsequently, the clutch is turned off by the clutch lever 11, the spool 10 is freely rotated, and the fishing line is paid out by the weight of the weight attached to the fishing line. When the fishing line is paid out, the water depth display on the display unit 5 increases in accordance with the amount of payout. Further, when the fishing line is paid out, the rotation of the spool 10 is controlled by the gear shaft 14 via the gear mechanism.
The rotation of the screw shaft 14 causes the fishing line guide 15 to reciprocate along the spool 10. When the device reaches the shelf, the clutch is turned on by the clutch lever 11 to stop the feeding of the fishing line.

When there is a fish hit, the handle 2 is operated to wind up the fishing line. When the fishing line is wound, the water depth display on the display unit 5 decreases according to the amount of winding. Also during this winding, the rotation of the spool 10 is transmitted to the screw shaft 14 via the gear mechanism, and the screw shaft 14 rotates to rotate the fishing line guide 1.
5 reciprocates along the spool 10. As a result, the fishing line is substantially uniformly wound on the spool.

On the other hand, when the primary battery 21 is exhausted, the fact is displayed on the display unit 5. When the angler knows that the primary battery 21 has been exhausted, the angler turns the two screws 26 to rotate the lid 24.
Remove. Then, the old primary battery 21 is taken out and replaced with a new primary battery 21. The control unit 30 is provided with a backup capacitor, and even if power is not supplied at the time of battery replacement, various data displayed and stored will not disappear for an appropriate period of time. Note that power may be supplied from the capacitor 37 instead of the backup capacitor.

Here, since the power supply (solar battery 34) of the power supply control circuit 38 is provided separately from the power supply (primary battery 21) of the control unit 30, the primary battery 21 is not consumed when the power supply is cut off. Consumption can be suppressed. In addition, the power supply on the power supply control circuit 38 side can supply power for a long time because of the solar cell 34. Further, since the capacitor 37 is arranged between the capacitors 37, power can be supplied to the power supply control circuit 38 regardless of the presence or absence of light irradiation.

[Other Embodiments] (a) Instead of the primary battery 21, a rechargeable secondary battery 28 may be used as a power source for the control unit 30 and the display unit 5, as shown in FIG. In this case, the backflow prevention circuit 36 may be connected to the secondary battery 28, and the secondary battery 28 may be charged by the electromotive force of the solar battery 34. As a battery used for the secondary battery 21, a small and lightweight secondary battery such as a nickel-cadmium battery and a lithium ion battery is preferable. Further, a capacitor may be used instead of the secondary battery.

(B) The primary battery 21 is not limited to a button battery, but may be a manganese dry battery such as an AA battery or an alkaline battery.

(C) As a power source of the power source control circuit 38, a normal primary battery or a secondary battery may be used instead of the solar battery 34.

(D) In the present embodiment, the power supply device according to the present invention is mounted on a manually wound dual-bearing reel. However, in an electric reel having an internal power supply for driving a display unit and a control unit,
This power supply can also be used as an internal power supply.

[0057]

According to the present invention, when the power supply operation switch is off, only the power of the second power supply is consumed and the power of the first power supply is not consumed. Therefore, when the power supply operation switch is in the off state, the first power supply is not consumed and the first power supply is not consumed.
Power consumption of the power supply can be suppressed.
