Multidirection input device

Abstract

The present invention provides a multidirectional input apparatus capable of making thin form design as well as smooth leaning motion of its operation axis. The solving means is describe in the following. The support parts 2d, 2f, 4d, 4e are respectively mounted at the both ends of the first and the second linking members 2, 4 to support the linking members 2, 4 in the frame 1. The second linking member 4 has a linking part 4a that has a second slot 4g formed between the support parts 4d and 4e. The linking part 4a connects across the lower portion of the first linking member 2 to dispose the first linking member 2 so as to allow the linking part 4a to locate inside the coiled spring 9.

Description

technical field [0001] The present invention relates to a multi-directional input device capable of simultaneously operating a plurality of electrical components by operating an operating shaft. Background technique [0002] Previous multi-directional input devices, such as Figure 20 As shown, there is a box-shaped case 31, and a hole 31b is formed in the center of the upper plate 31a of the case 31. As shown in FIG. Inside the casing 31, the first and second interlocking members 32, 33 are mutually supported rotatably in the vertical direction. [0003] The first interlocking member 32 has a substantially U-shaped connecting portion 32a, and a first elongated hole 32b is formed in the longitudinal direction of the connecting portion 32a. At the lower portion of one end portion of the connecting portion 32a, a locking claw 32c parallel to the longitudinal direction of the connecting portion 32a is protrudingly formed. In addition, protrusions 32d, 32d are protrudingly for...

Problems solved by technology

Therefore, it is difficult to reduce the thickness of conventional multi-directional input devices

[0016] In addition, since the positions where the respective projections 32d, 33d of the first or second interlocking members 32, 33 contact the push-up member 36 deviate from the center, on the push operation shaft 34, the first or second interlocking members 32, 33 When the push-up part 36 is pressed down, the push-up part 36 will be inclined so that the push-up part 36 is guided, so a rough feeling will be produced on the central hole 36c and the guide surface 38a of the bottom plate 38.

[0017] Therefore, it is difficult for the push-up member 36 to be pushed down smoothly, and the operation feeling when pushing the operation shaft 34 is not good.

[0018] In addition, because the position of the lower end of the coil spring 37 is not fixed, when the push-up member 36 moves up and down, the lower end of the coil spring 37 also moves, which will cause the pressing force of the push-up member 36 to be pressed downward to be discrete, and push the push-up member 36 downward. The operating force required to operate the shaft 34 is not constant
