Abstract

PURPOSE: To measure and indicate the length of a fishing line or the like with high accuracy, by performing magnetic recording at a regular interval on the fishing line or the like and detecting and counting magnetic changes with the relative movement of the line.
CONSTITUTION: A magnetic material is continuously provided on a fishing line 2 or the like. Magnetic signals are recorded at a regular interval such as 1mm on the magnetic material. When the line 2 is passed through the guide hole 3 of a signal detection unit 1, magnetic changes due to the movement of the line are detected by a sensor 4. The detection signals are applied to a counter circuit 5, which sequentially performs addition. The value counted by the circuit 5 is indicated on a display unit 8. When the line 2 is wound, subtraction signals are applied from an addition/subtraction changeover circuit 7 to the counter circuit 5 to cause the circuit 5 to perform subtraction instead of addition. A reset circuit 6 is used to set the indication of the display unit 8 at zero.
