Pointing device
A pointing device includes: a substrate; an operation member that is provided tiltably with respect to the substrate, and includes a protrusion protruded from one of an inner wall and an outer wall; and a rotation member that is provided rotatably on the substrate, and includes a hole which the protrusion enters when the rotation member overlaps the operation member; wherein the rotation member rotates in conjunction with the operation member when the protrusion contacts an edge of the hole according to rotation of the operation member, wherein the hole is formed in a range in which the protrusion is movable by tilt of the operation member.
1. A pointing device comprising:
a substrate;
an operation member that is provided tiltably with respect to the substrate, and includes an inner wall, an outer wall, and a protrusion protruded from one of the inner wall and the outer wall; and
a rotation member that is provided rotatably on the substrate, has a cylindrical shape, and includes a hole which the protrusion enters when the rotation member overlaps the operation member;
wherein the rotation member rotates in conjunction with the operation member when the protrusion contacts an edge of the hole according to rotation of the operation member,
wherein the hole is formed in a range in which the protrusion is movable by tilt of the operation member.
2. The pointing device as claimed in claim 1 , wherein
the protrusion is protruded from the inner wall of the operation member, and the operation member overlaps the rotation member so as to cover the rotation member from an outside.
3. The pointing device as claimed in claim 1 , wherein
the rotation member includes one of a recessed and projecting part and a hole which are provided along a rotation direction of the rotation member, and
the substrate includes a first detector that detects the rotation of the rotation member based on the one of the recessed and projecting part and the hole.
4. The pointing device as claimed in claim 1 , further comprising:
a second detector that detects that the operating member is pressed.
5. A pointing device comprising:
a substrate;
an operation member that includes a base with a first protrusion, and is provided tiltably with respect to the substrate; and
a housing member that biases the first protrusion toward the substrate and houses the base;
wherein a second protrusion is provided on an inner peripheral surface of the housing member so as to avoid a range in which the first protrusion is movable by tilt of the operation member,
wherein the housing member rotates in conjunction with the operation member when the first protrusion directly contacts the second protrusion according to rotation of the operation member.
6. The pointing device as claimed in claim 5 , further comprising:
a rotation member that is provided rotatably on the substrate, and houses the housing member so that an inner peripheral surface of the rotation member faces an outer peripheral surface of the housing member,
the inner peripheral surface of the rotation member includes a first recessed and projecting part, and the outer peripheral surface of the housing member includes a second recessed and projecting part to be engaged with the first recessed and projecting part.
7. The pointing device as claimed in claim 5 , wherein
an outer peripheral surface of the housing member includes a recessed and projecting part, and
the substrate includes a detector that detects rotation of the housing member based on the recessed and projecting part.
