Lever input device
View Patent ↗A lever input device includes: a lever which is tiltable in a first direction orthogonal to an axis of the lever about the axis due to an operation by a user; a swing arm which engages with the lever and swings along with the tilting of the lever in the first direction and amplifies a displacement amount of the lever at the time of tilting; and a magnet body mounted on the swing arm, wherein the swing arm is elongated along a second direction which is a direction along the axis, is configured such that distance (D 13 ) between a swing fulcrum and a mounting portion of the magnet body becomes larger than distance (D 12 ) between the swing fulcrum of the swing arm and an engaging portion of the swing arm with the lever.
1. A lever input device comprising:
a lever including an operation portion and a first engaging portion;
a swing arm including a swing fulcrum, a second engaging portion, and a third engaging portion, the swing arm engaging with the first engaging portion of the lever at the second engaging portion;
a body to be detected engaging with the swing arm at the third engaging portion of the swing arm;
a detector arranged so as to opposedly face the body to be detected; and
a slider,
wherein the lever is tiltable in a first direction along with movement of the operation portion,
the swing arm elongating along a second direction orthogonal to the first direction, and the swing fulcrum, the second engaging portion, and the third engaging portion being arranged along the second direction,
a distance between the swing fulcrum and the third engaging portion is set larger than a distance between the swing fulcrum and the second engaging portion,
the swing arm displacing the body to be detected engaging with the third engaging portion in the first direction by rotating about the swing fulcrum along with tilting of the lever in the first direction, and amplifying a displacement amount of the body to be detected with respect to a displacement amount of the first engaging portion of the lever at the time of tilting,
the lever is tiltable also in the second direction due to the movement of the operation portion, and
the slider pivotally supports the swing fulcrum of the swing arm, and is displaced in the second direction together with the swing arm along with the tilting of the lever in the second direction.
2. A lever input device comprising:
a lever including an operation portion, a first engaging portion, and a pivotally supporting portion;
a swing arm including a swing fulcrum, a second engaging portion, and a third engaging portion, the swing arm engaging with the first engaging portion of the lever at the second engaging portion;
a body to be detected engaging with the swing arm at the third engaging portion of the swing arm; and
a detector arranged so as to opposedly face the body to be detected,
wherein the lever is tiltable in a first direction along with movement of the operation portion,
the swing arm elongating along a second direction orthogonal to the first direction, and the swing fulcrum, the second engaging portion, and the third engaging portion being arranged along the second direction,
a distance between the swing fulcrum and the third engaging portion is set larger than a distance between the swing fulcrum and the second engaging portion,
the swing arm displacing the body to be detected engaging with the third engaging portion in the first direction by rotating about the swing fulcrum along with tilting of the lever in the first direction, and amplifying a displacement amount of the body to be detected with respect to a displacement amount of the first engaging portion of the lever at the time of tilting,
the operation portion, the pivotally supporting portion, and the first engaging portion are arranged in order from one end of the lever, and the lever is tiltable in the first direction using the pivotally supporting portion as a tilting fulcrum, and
the pivotally supporting portion and the first engaging portion are spherical.
