Abstract

An output system according to one aspect of the present invention includes a magnet disposed on an axis of a pointer of a gauge, first and second magnetic sensors that are each configured to have a sensitivity axial direction, and an output unit configured to output indicated value information generated based on detection values of the magnetic sensors. Also, first and second directions are set to intersect each other on the axis of the pointer, and the first magnetic sensor is disposed such that the sensitivity axial direction thereof extends in the first direction, and the second magnetic sensor is disposed such that the sensitivity axial direction thereof extends in the second direction.

First claim

1 . An output system for outputting a value indicated by a pointer of a gauge that has an axis and is configured to rotate around the axis, the output system comprising:
a magnet disposed on the axis of the pointer; a first magnetic sensor and a second magnetic sensor that are each configured to have a sensitivity axial direction in which magnetic field detection sensitivity is at the maximum; and an output unit configured to output indicated value information relating to the value indicated by the pointer, the indicated value information being generated based on values that are respectively detected by the first magnetic sensor and the second magnetic sensor, wherein a first direction and a second direction are set to intersect each other on the axis of the pointer, the first magnetic sensor is disposed such that the sensitivity axial direction of the first magnetic sensor extends in the first direction, and the second magnetic sensor is disposed such that the sensitivity axial direction of the second magnetic sensor extends in the second direction.

2 . The output system according to claim 1 ,
wherein the first direction and the second direction are set to be orthogonal to each other on the axis of the pointer.

3 . The output system according to claim 1 ,
wherein the output unit is configured to output the indicated value information to an external device through wireless communication.

4 . The output system according to claim 1 ,
wherein the magnet is formed into a circular shape.

5 . A gauge comprising:
an axis; a dial that includes a scale provided in an arc shape around the axis; a pointer configured to rotate around the axis on the dial; a main body portion whose upper end portion is open and that includes an internal space and houses the dial and the pointer in the internal space in a state in which the scale faces the upper end portion side; a transparent cover for covering the upper end portion of the main body portion in a state in which the dial and the pointer are visually recognizable; and the output system according to claim 1 , wherein the magnet is disposed on the axis of the pointer, and the first magnetic sensor, the second magnetic sensor, and the output unit are attached near a center of a surface of the transparent cover on the internal space side in a state in which the scale of the dial is not concealed.

6 . The gauge according to claim 5 ,
wherein the output system further includes one or more substrates for disposing the first magnetic sensor, the second magnetic sensor, and the output unit, and the one or more substrates each include a window portion for visually recognizing the magnet.
