Multiway input device

Abstract

The invention provides a multidirectional input device the quality of which is not hampered over a long period of time by regulating a tilting direction, even if an undesired operation is performed. This multidirectional input device is equipped with a housing 1 comprising a synthetic resin material and having an opening part 1c, an operation shaft 18 comprising a metal material and projecting from the opening part 1c of the housing 1, which can be tilted in a prescribed direction, and a detecting means 2, 9, 16, 17, to detect the tilting action of the operation shaft 18. A guide plate 4 comprising a metal material and having a plate-shaped part 4a to cover a part of the opening part 1c and a window hole part 4b to make the operation shaft 18 project is provided on the opening part 1c of the housing 1, and a plurality of recessed groove parts 4c extending in the tilting direction of the operation shaft 18 are provided in the window hole part 4b. Thereby, when the operation shaft 18 is tilted, the tilting direction of the operation shaft 18 is regulated by the recessed groove part 4c of the guide plate 4.

Description

technical field [0001] The present invention relates to a multi-directional input device used in input operation parts of various electronic devices, and particularly relates to a structure of a multi-directional input device that detects the tilting direction of an operating shaft. Background technique [0002] As an existing multi-directional input device structure, a known structure is: use the bearing portion on the top surface of the box-shaped housing to cooperate to hold the operating shaft so that it can be tilted and moved up and down; The switch contact composed of the movable contact on the permanent substrate and the fixed contact part facing it is provided with guide grooves in four directions on the bearing part of the box-shaped housing to limit the tilting direction of the operation shaft to four directions ( For example, refer to Patent Document 1). [0003] Hereinafter, a conventional multi-directional input device will be described with reference to the d...

AI Technical Summary

Problems solved by technology

[0013] However, in the above-mentioned conventional multi-directional input device, there is a problem that the operation shaft is formed of a metal material in order to increase the strength, and when the operation shaft is rotated, the casing made of synthetic resin restricts the movement of the operation shaft in the tilting direction. The corners of the guide grooves of the body are ground, and the angle of tipping may increase in a direction that cannot be tipped originally, which may damage the quality.
