The reel control unit 30 adjusts the rotation speed of the motor 12 by increasing or decreasing the duty ratio of the motor drive current so that the speed becomes a preset speed according to the pulse. The PWM drive circuit 31 includes an FET as a drive element for driving the motor 12. PW
The M drive circuit 31 drives the motor 12 at a variable speed by controlling the duty ratio of the motor drive current by the reel control unit 30.

The spool sensor 41 is composed of two reed switches arranged side by side. The reed switch detects two magnets mounted on the magnet wheel. The number of rotations of the reel can be detected by counting the detection pulses by the spool counter 42. Further, the rotation direction of the spool 10 can be detected based on which reed switch has issued the detection pulse first.

The spool counter 42 is a counter for counting the number of times the spool sensor 41 is turned on and off. Rotational position data relating to the number of rotations of the spool is obtained from the counted value. The count value of the spool counter 42 decreases when the spool 10 rotates forward (rotation in the line feeding direction), and increases when the spool 10 rotates reversely. The storage unit 43 is composed of a nonvolatile memory such as an EEPROM, for example, and stores data of a learning result, various data used when calculating the yarn length, and the like.

Next, a specific control process performed by the reel control unit 30 will be described with reference to a control flowchart shown in FIG. When the electric reel is connected to the external power supply PS via the power cord 18, initialization is performed in step S1 of FIG. In this initial setting, the count value of the spool counter 42 is reset, various variables and flags are reset, and the water depth display mode is set from the top.

Next, in step S2, display processing is performed. In the display processing, various kinds of display processing such as water depth display are performed. Here, in the mode from the top, the water depth reference water depth is displayed in the water depth display area 5a. When the bottom position is set by the bottom memo switch SM, the bottom position is displayed in the bottom depth display area 5b. In step S3, it is determined whether any switch of the switch operation unit 6 has been pressed. If a switch input has been made, the process moves from step S3 to step S6 to execute a switch input process.
If the switch input has not been made, the process proceeds to step S4.

In step S4, it is determined whether or not the spool 10 is rotating. This judgment is made by the spool sensor 4
Judgment is made based on the output of 1. If the rotation of the spool 10 is detected, the process proceeds from step S4 to step S7. In step S7, each operation mode process is executed.
In step S5, it is determined whether another command or input has been made. If another command or input has been made, the process proceeds from step S5 to step S8 to execute other processing.

In the switch input processing of step S6, FIG.
In step S11, it is determined whether the winding mode has been set. This determination is made based on whether or not the mode switch MD has been pressed. When the mode switch MD is pressed, the process moves from step S11 to step S15. In step S15, a bobbin mode process is executed. Step S1
At 2, it is determined whether or not the rotary switch RS has been moved. If the rotary switch RS has been moved, the process proceeds to step S16 to perform a motor control process. In step S13, it is determined whether the rotary switch RS is being rotated. If "YES" here, the process proceeds to a step S17 to perform a speed control process.
In step S14, it is determined whether or not another switch has been operated. The operation of the other switches includes the operation of the bottom memo switch SM, the mode changeover switch MK, and the like. If another switch input is made, step S14
Then, the process proceeds to step S18 to perform another switch input process according to the operated switch input such as setting to the bottom shelf value of the current water depth.

In the motor control process of step S16 in FIG. 6, as shown in FIG. 7, the process starts from a state where the rotary switch RS is turned on by the moving operation. First, in step S21, it is determined whether or not the rotary switch RS has been turned on twice within a predetermined time. If "NO" here, that is, if the rotary switch RS is kept on, the process proceeds to step S22, and it is determined whether the motor 12 is on. If the motor 12 is off, step S2
Then, the process proceeds to step S3, where the motor 12 is rotated, and the process proceeds to step S24. If "YES" is determined in the step S22, that is, if the motor 12 is already on, the process proceeds to a step S24. In step S24, it is determined whether or not the rotary switch RS is off. When the rotary switch RS is turned off, the process proceeds to step S25, and the rotation of the motor 12 is stopped. In steps S21 to S25, the jogging winding for rotating the motor 12 while the rotary switch RS is pressed can be performed.

On the other hand, if "YES" is determined in the step S21, the process shifts to a step S26 to determine whether or not the motor 12 is rotating. If the motor 12 is rotating, the rotation is stopped in step S28. If the motor 12 is not rotating, the rotation is started in step S27. Here, when the motor 12 is not rotating, the rotary switch RS is turned on twice so that the motor 12
Can be performed.

In the speed control process of step S17 in FIG. 6, as shown in FIG. 8, the process starts from a state where the rotary switch RS is rotated. In step S31, the rotational displacement X of the rotary switch RS is
To detect through. In step S32, a motor speed increasing / decreasing process is performed. In the motor speed increasing / decreasing process, the reel control unit 30 determines the rotation speed with respect to the rotation displacement X, and changes the rotation speed of the motor 12 by increasing / decreasing the duty ratio of the motor drive current.

In each operation mode process in step S8 in FIG. 5, it is determined in step S41 in FIG. 9 whether or not the rotation direction of the spool 10 is the line feeding direction. This determination is made based on which reed switch of the spool sensor 41 has emitted the pulse first. When it is determined that the rotation direction of the spool 10 is the line feeding direction, the process proceeds from step S41 to step S42. In step S42, every time the spool speed decreases, the data stored in the storage unit 43 is read from the spool speed to calculate the water depth. This water depth is displayed in the display processing of step S2. Step S4
In 2, whether the obtained water depth matched the bottom position, that is,
Determine if the device has reached the bottom. The bottom position is set in the storage unit 43 by pressing the bottom memo switch SM when the device reaches the bottom. In step S43,
It is determined whether the mode is another mode. If the mode is not another mode, each operation mode process is ended and the process returns to the main routine.

If the water depth matches the bottom position, step S42
Then, the process proceeds to step S44, and the buzzer 40 is sounded to notify that the device has reached the bottom. In the case of another mode, the process shifts from step S43 to step S45 to execute another designated mode. When the rotation of the spool 10 is determined to be in the line winding direction, the process proceeds from step S41 to step S46. In step S46, the data stored in the storage unit 43 is read from the spool rotation speed to calculate the water depth. This water depth is displayed in the display processing of step S2, and it is determined whether or not the water depth matches the hull stop position. If the reel has not been wound to the hull stop position, the process returns to the main routine. When the ship reaches the hull stop position, the process proceeds from step S46 to step S47. Step S4
At 7, the buzzer 40 sounds to notify that the device is at the shore. In step S48, the motor 12 is turned off. As a result, the fish is arranged at a position where it can be easily taken in when the fish is caught. This hull stop position is set, for example, when the spool 10 has stopped for a predetermined time or more within a water depth of 6 m.
