Abstract

A multidirectional input device of the present disclosure includes a case, a movable body that is mounted on the case so as to be movable in a plurality of directions with a predetermined neutral position as a base point, a first position detector that outputs a first signal in response to a position of the movable body, a second position detector that outputs a second signal when the movable body is located at the neutral position, and a controller that detects a moving direction of the movable body by the first signal. The controller corrects a threshold value for determination for detecting the moving direction in response to the first signal and the second signal.

First claim

The invention claimed is:

1. A multidirectional input device comprising:
a case;
a movable body that is mounted on the case so as to be movable in a plurality of directions with a predetermined neutral position as a base point;
a first position detector that outputs a first signal in response to a position of the movable body;
a second position detector that outputs a second signal when the movable body is located at the neutral position; and
a controller that detects a moving direction of the movable body by the first signal, wherein
the controller corrects a threshold value for determination for detecting the moving direction in response to the first signal and the second signal; and
a third signal obtained by superimposition of the first signal output from the first position detector with the second signal output from the second position detector is input to the controller.

2. The multidirectional input device according to claim 1 , wherein
the controller outputs a predetermined periodic signal to the second position detector, and the second position detector outputs the second signal synchronized with the predetermined periodic signal to the first position detector.
