AI Technical Summary

Technical Problem

When used repeatedly, the retaining mechanism of the operating shaft is easily worn, resulting in a shortening of product life and non-linear reaction force characteristics, which can easily lead to erroneous operation.

Method used

The combined holding mechanism of upper and lower plate springs is adopted to ensure that the operating shaft is elastically maintained in a neutral state through the plane shape and relative position of upper and lower plate springs, and wear is avoided through a non-sliding design. At the same time, the non-linear reactivity characteristics are achieved by using the anisotropic rigidity of plate springs.

Benefits of technology

It extends the product life of multi-directional input devices, reduces the possibility of misoperation, and provides stable nonlinear reactive force characteristics, suitable for rocker control of handheld gaming devices.

Abstract

To provide a multidirectional input device which has a long product life and has desired nonlinear reaction force characteristics to tilt operation on an operation shaft.SOLUTION: A multidirectional input device 1 includes: an upper housing 61; a first rotation member 62a which is held by the upper housing 61 so as to be rotatable around a first axial direction; a second rotation member 62b which is held by the upper housing 61 so as to be rotatable around a second axial direction; an operation shaft 63 for rotating the first rotation member 62a and the second rotation member 62b, in response to tilt operation applied from a user; and a holding mechanism 66 which is held by the upper housing 61, and elastically holds the operation shaft 63 in a neutral state. An upper leaf spring 9a and a lower leaf spring 9b of the holding mechanism 66 have planar shapes which are vertically inverted, in plan view from a height direction.SELECTED DRAWING: Figure 12
