Abstract
A multi-stage detector capable of accurately detecting an input operations in steps. Since the vertical lengths of a plurality of displacement press members (137) and (138) displaceably supported on an up-and-down operation member (131) and downwardly energized by a press biasing mechanism (139) are different from each other. When the up-and-down operation member (131) is displaced downward, a plurality of press-contact detection elements (135) and (136) are pressed in order by the displacement press members (137) and (138).
Claims22
A multi-stage detector for detecting a downward input operation in steps, comprising:
- an up-and-down operation member receiving the input operation;
- an operation support mechanism supporting the up-and-down operation member such that the up-and-down operation member is displaceable upward and downward;
- n+1 (where n means a natural number) displacement press members supported on the up-and-down operation member such that the displacement press members are displaceable upward and downward;
- a press biasing mechanism biasing each of the displacement press members downward against the up-and-down operation member;
- n+1 press-contact detection elements detecting press contact from above;
- and
- a base member on which the n+1 press-contact detection elements are placed at positions where the n+1 displacement press members are each opposed from above,
- wherein the distances between the displacement press members and the opposed press-contact detection elements are different from each other in steps.
