Abstract:
1. A swing type input apparatus comprising: a housing; an operation knob swingably supported by the housing; a circuit substrate received in the housing so as to intersect the rotation center line of the operation knob; a magnetic sensor attached to the circuit substrate; a magnet holder driven by the operation knob such that the magnet holder is rotated integrally with the operation knob; a magnet held by the magnet holder such that the magnet is positioned so as to intersect the rotation center line of the operation knob and is close to and faces the magnetic sensor; and a magnetic shield case fixed to the circuit substrate so as to cover at least both of the magnetic sensor and the magnet, wherein the magnetic shield case includes an assembly of a first shield case and a second shield case combined in a box, the distance from the boundary between the first and second shield cases to the rotation center line of the operation knob is set longer than the distance from an outer edge of the magnet to the rotation center line of the operation knob, a grounding tab extending substantially orthogonal to the circuit substrate is provided for either of the first and second shield cases, and the grounding tab is electrically connected to a grounding conductor of the circuit substrate.
