Multii-directional input device

Abstract

A multidirectional input device to surely prevent looseness without sacrificing operability even if the size of an operation body and the weight thereof are increased is provided with: a housing (1); the operation body (3) having a drive part (4), a first operation shaft (5) and an operation knob (6) mounted to the tip of the first operation shaft (5); a second operation shaft (7) vertically movably held in a guide hole (3a) formed in the operation body (3); and a coil spring (9) mounted between the upper surface of the housing (1) and the operation knob (6). By pressing an arbitrary position of the operation knob (6) to tilt the first operation shaft (5), the drive part (4) selectively turns on a plurality of push-switches (S2) corresponding to the tilting direction, and by pressing a push-knob (8) mounted to the upper end of the second operation shaft (7) downward, the lower end (7a) of the second operation shaft turns on a push-switch (S1).

Description

technical field [0001] The present invention relates to a multi-directional input device used in input operation units of various electronic devices, and more particularly to a multi-directional input device capable of performing different input actions such as tilting operation and pressing operation. Background technique [0002] In the past, the main components of this multi-directional input device were: [0003] The shell has an opening on its upper surface, and a push button switch for lifting detection and a plurality of push button switches for dumping detection are respectively arranged in the center of the inner bottom surface and its surroundings; [0004] An operating body, which has a guide hole penetrating up and down, and is composed of a driving part housed in the housing and a first operating shaft connected to the driving part and protruding from the opening of the housing; [0005] The second operating shaft is fitted and held in the guide hole of the ope...

Problems solved by technology

[0009] However, the above-mentioned conventional multi-directional input device is because its structure is that the driving part of the operating body is accommodated in the inside of the casing, and the push button switches for tilting detection and lifting detection are arranged between the driving part and the inner bottom surface of the casing. Therefore, the height space for the coil spring is limited by the internal space of the housing. It is actually very difficult to install a coil spring with a large elastic force in such a limited space.

In such a structure, there is not much problem when the weight of the operating body is not too large, but, for example, when used as a multi-directional input device for a v
