Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric fishing reel, and more particularly, to an electric fishing reel which can be supplied with power from a large-capacity battery power supply and selectively use a small-sized attached battery unit.

[0002]

2. Description of the Related Art An electric reel is conventionally used for deep-field fishing on a fishing boat or the like. The electric reel not only performs electric winding by motor driving, but also calculates the amount of thread to be drawn out from the number of rotations of the spool using a central processing unit (central processing unit), and automatically performs the operation up to a predetermined water depth. Generally, it is provided with a function as a so-called shelf reel which can take out a shelf for unwinding a thread.

As a power supply for such an electric reel, a battery built in or detachably provided in the reel body is used, or a battery power supply such as a power supply for a ship is used. When a battery is used as a power source, if the battery is not sufficiently charged, or if a fully charged battery has a long fishing time, the battery becomes exhausted and the voltage becomes unstable. In addition, a situation may occur in which the central processing unit cannot perform calculations for shelving.

Japanese Patent Application Laid-Open No. 3-289328 discloses that a battery detachably attached to an electric reel body is connected to a battery power source to charge the battery when the rotation of the motor is stopped. . Such a method prevents the charging voltage of the battery from decreasing. Further, Japanese Patent Application Laid-Open No. 2-119735 discloses that a capacitor is built in for backup of control data such as the amount of thread to be fed.

[0005]

However, the battery mounted on the electric reel body is generally large in size and heavy, so that the angler has a heavy burden to hold and operate the fishing rod for a long time. There is. Also,
In recent years, electric reels have become smaller and lighter,
Reels suitable for use in shallow and mid-depth fields have been developed. However, when used in shallow fields (100 m or less), there is often no need for electric winding, so the problem that the battery becomes an obstacle is encountered. is there. In addition, a large battery is provided for a small electric reel, and power is supplied to the central processing unit and display device by connecting to a permanent power supply for the fishing boat, so the movement range on the boat is limited. And the power cable hindered the manual operation of the rod and reel.

In the conventional example described in the above-mentioned Japanese Patent Application Laid-Open No. 2-119735, the operation of the central processing unit is stopped during this time even though the backup of control data such as the amount of thread unreeling can be made. However, there is a problem in that data such as spool rotation detection and the position of the extended yarn long shelf cannot be sent to a display and displayed.

Is connected, the voltage level determiner 35
Turns on the operation switch 36 and directly applies the voltage from the power supply receptacle 10 to the central processing unit 7a. When it is determined that the external battery power supply 15 is connected to the power supply receptacle 35, the voltage level determination unit 35 operates the operation switch 36.
Is turned off, and the voltage from the power supply receptacle 10 is applied to the central processing unit 7a via the voltage converter 37. When the external battery power supply 15 is connected to the power supply receptacle 10, the supplied voltage is applied to the central processing unit 7 a via the voltage converter 37 by the external battery power supply 15.
Is supplied with a voltage of 12 V, and it is necessary to reduce the voltage of 12 V so as to be compatible with the operating voltage range of the central processing unit 7 a.

Next, a specific circuit diagram corresponding to the block diagram shown in FIG. 3 will be described with reference to FIG.

The power supply receptacle 10 is connected to the V ⁺ line via a backflow preventing diode D1. A series circuit of resistors R1 and R2 and a resistor R3 are connected between the V ⁺ line and the ground.
And R4 are connected in series, and a resistor R1
The connection point between R2 and R2 is connected to the SET1 terminal of the power supply voltage monitoring IC 40, and the connection point between the resistors R3 and R4 is connected to the SET2 terminal of the power supply voltage monitoring IC 40. As the power supply voltage monitoring IC 40, for example, Maxim I
CL7665 is used. The OUT1 terminal of the power supply voltage monitoring IC 40 is connected to the port 1 of the central processing unit 7a.
The two terminals are connected to port 2 respectively. Resistance R
1, R2, R3, R4 and the power supply voltage monitoring IC 40 constitute the voltage level determination unit 35 shown in FIG. A voltage regulator IC (REG1) is provided between the anode of the backflow prevention diode D1 and the power supply terminal VDD of the central processing unit 7a.
41 are connected. This voltage regulator IC 41
Correspond to the voltage converter 37 shown in FIG. Further, a switch composed of transistors Q1, Q2 and resistors R5, R6, R7 is connected in parallel with the voltage regulator IC41. This switch corresponds to the operation switch 36 shown in FIG.

A voltage obtained by dividing the voltage on the V ⁺ line by resistors R1 and R2 is applied to the SET1 terminal of the power supply voltage monitoring IC 40, and a voltage obtained by dividing the voltage on the V ⁺ line by the resistors R3 and R4 is applied to the SET2 terminal. . When the voltage of the V ⁺ line exceeds 6.5 V, the OUT1 terminal of the power supply voltage monitoring IC 40 outputs an L level signal (GND voltage level), and the OUT2 terminal outputs an H level signal. When the voltage on the V ⁺ line is 2.7 V or more and 6.5 V or less, both the OUT1 terminal and the OUT2 terminal output an H level signal. Also,
When the voltage of the V ⁺ line drops below 2.7 V, the OUT1 terminal outputs an H-level signal and the OUT2 terminal outputs an L-level signal.

Next, the operation of the electric circuit shown in FIG. 4 will be described.

When an external battery power supply 15 is connected to the power supply receptacle 10 and a voltage of 6.5 V or more is applied to the V ⁺ line, the OUT1 terminal of the power supply voltage monitoring IC 40 becomes L
Since it is at the level, current flows from the resistor R5 to the diode D2, and no current flows to the resistors R6 and R7. As a result, the transistors Q1 and Q2 are both turned off, and the voltage on the V ⁺ line is applied to the power supply terminal VDD of the central processing unit 7a via the voltage regulator IC 41 and the diode D5. At this time, the capacitor C3 is charged at the same time. This capacitor C3 corresponds to the backup storage battery 38 shown in FIG.

The cartridge power supply unit 16 is connected to the power supply receptacle 10, and the operating range of the cartridge power supply unit 16 from 2.7 V to 6.5 is set on the V ⁺ line.
When the voltage of V is applied, the power supply voltage monitoring IC 40
Since both the UT1 terminal and the OUT2 terminal are at the H level, no current flows through the resistor R5, and both the transistors Q1 and Q2 are turned on. The voltage supplied by the cartridge power supply unit 16 bypasses the voltage regulator IC 41 and is directly applied to the power supply terminal VDD of the central processing unit 7a.

The OUT1 and OUT2 terminals of the power supply voltage monitoring IC 40 are connected to the port 1 and the port 2 of the central processing unit 7a.
The central processing unit 7a constantly monitors the voltage levels (logic levels) of the ports 1 and 2 during operation and controls the operation mode of the electric reel. FIG.
Is a flowchart showing a control program executed by the central processing unit 7a.

When the control program is started, it is first determined whether or not the port 1 of the central processing unit 7a is at the H level (S1). If the port 1 is not at the H level, that is, if the port 1 is at the L level (S1: No), it is determined whether the port 2 is at the L level (S2).
If the port 2 is at L level (S2: Yes), S
1 and waits until at least one of the ports 1 and 2 becomes H level. When port 2 is not at L level, that is, when port 2 is at H level (S
2: No), since the port 1 is at the L level and the port 2 is at the H level, it is determined that the external battery power supply 15 is connected to the power receptacle 10, and output to the port 3 is permitted (S3). Thereby, the electric reel is set to the electric winding mode. The spool 2 is rotated by the motor 5 via the speed reduction mechanism 4 so that the winding of the fishing line can be performed electrically.

Next, when it is determined that the port 1 of the central processing unit 7a is at the H level (S1: Yes), it is then determined whether or not the port 2 is at the L level (S5).
When the port 2 is not at the L level, that is, when the port 2 is at the H level (S5: No), both the ports 1 and 2 are at the H level.
Since the level is the level, it is determined that the cartridge power supply unit 16 is connected to the power supply receptacle 10, and output to the port 3 is prohibited (S6). In this case, the line length measurement display mode is executed (S7), and the electric winding of the fishing line cannot be performed. However, it is possible to display data such as the amount of the line drawn out (water depth value) on the display unit 8. In this case, it operates as a shelf reel.

Port 1 is at H level (S1: Ye)
s) When port 2 is at L level (S5: Yes),
It is determined that the power supply voltage state cannot operate as a shelf reel, and an interrupt to port 1 and port 2 is permitted (S8), and the central processing unit 7a enters the stop mode (S9). At this time, all functions of the central processing unit 7a (spool rotation detection and thread length calculation display function) are stopped. When the central processing unit 7a is in the stop mode, it is determined whether or not there is an interrupt signal at the ports 1 and 2 (S10). If it is determined that there is an interrupt signal, the process returns to S1 and executes the program again. I do.

FIG. 5 shows another example of the electric configuration of the electric reel. In this example, two independent voltage detection ICs 50 are used to determine the voltage level on the V ⁺ line.
(For example, Ricoh's RH5VL27A) and 51 (for example, Ricoh's RH5VL55A). These two voltage detection ICs 50 and 51 constitute the voltage level determination unit 35 shown in FIG. Each voltage detection IC5
0 and 51 are V ⁺ lines of 2.7 V or less, respectively.
When the voltage is 5 V or less, an L level is output to the OUT terminal. Therefore, when an external battery power supply 15 is connected to the power supply receptacle 10 and a voltage of 5.5 V or more is applied to the V ⁺ line, a signal of H level is output from each OUT terminal of the voltage detection ICs 50 and 51 to the central processing unit. Output to port 1 and port 2 of 7a.

The cartridge power supply unit 16 is connected to the power supply receptacle 10 so that the voltage on the V ⁺ line is 2.7.
If it is in the range from V to 5.5V, the voltage detection IC
An L-level signal is output from the OUT terminal 51 to the port 1 of the central processing unit 7a.
From the T terminal, an H-level signal is output to the port 2 of the central processing unit 7a.

When the voltage of the V ⁺ line is 2.7 V or less, an L level signal is output from the OUT terminal of each of the voltage detection ICs 50 and 51 to the port 1 of the central processing unit 7a.
Is output to port 2.

When both the port 1 and the port 2 are at the L level, the central processing unit 7a determines that the power supply voltage is in the range of 0 to 2.7 V, and the central processing unit 7a enters the stop state. When the port 1 is at the L level and the port 2 is at the H level, it is determined that the cartridge power supply unit 16 is connected, and the operation as a shelf reel is performed. Port 1
When both the port 2 and the port 2 are at the H level, it operates to permit the motor drive.
