Claims

[Scope of utility model registration request]

(1) A magnetic needle, a detector that rotates near the magnetic needle to detect when the magnetic needle passes, and a distance from the rotational reference point of the detector to the detection time when the detector detects when the magnetic needle passes. A direction meter equipped with an arithmetic processor that calculates angles.

(2) The detector consists of a sensitive switch that operates when it crosses a magnetic needle.
The compass described in section 1).

(3) The compass according to claim 1, wherein the detector is configured to sense light by passing light through a slit in a detection plate that rotates together with the magnetic needle.

(4) The compass according to claim 1, wherein the rotational reference point of the detector is determined by a microswitch that is brought into contact with a support arm that rotates with the detector.

(5) The compass according to claim 1, wherein the rotational reference point of the detector is determined by detecting the passage of a reference plate that rotates together with the detector using light.

(6) The direction meter according to claim (1) of the utility model registration, characterized in that it is an arithmetic processor power button-tary encoder.
