Multiway input device and assembling method therefor

Abstract

To provide a multidirectional input device, and its assembly method, capable of automatically resetting an operating body making a slide operation, with an operation area widely taken with little deviation of operating force by operating directions, and that, with an excellent assembling property. Inside a chassis 10, a large-diameter part 13a of the operating body 13, a circular coil spring 14 surrounding the large-diameter part 13a, and detection means such as sliding pieces 17, 18 detecting a slide direction and a slide volume of the operating body 13. A jig insertion hole 10c for letting in an assembling jig 30 for preliminarily retaining the circular coil spring 14 at assembly is provided beforehand at a chassis 10. When the operating body 13b is operated to slide through a protruded part 13b protruded from an opening 10b of the chassis 10, the large-diameter part pushes in the circular coil spring located in its sliding direction to extend it, so that, when the operating force is removed, the operating body automatically returns to the initial position by the restoring force of the circular coil spring.

Description

technical field [0001] The present invention relates to a multi-directional input device suitable for use in a game machine or a mobile phone, and an assembly method thereof, and more particularly to a multi-directional input device capable of performing predetermined inputs by sliding operations, and an assembly method thereof. Background technique [0002] Figure 21 It is a cross-sectional view showing a conventional multi-directional input device capable of performing predetermined input by sliding an operation portion (for example, refer to Patent Document 1). Figure 21 The shown multi-directional input device is mainly composed of a housing 1 formed by combining an insulating upper case 2 and a lower case 3, an operating body 4 slidably held on the housing 1, and a housing 4 held by the operating body 4. The first slider 5 and the second slider 6 that slide in the direction perpendicular to each other inside the housing 1 driven by the protruding portion 4a of the hous...

Problems solved by technology

[0008] As mentioned above, Figure 21 The conventional multi-directional input device shown does not have a reset mechanism for automatically returning the sliding operation body 4 to the initial position, so there is a problem that good operability cannot be obtained.

On the other hand, in the conventional example in which an O-ring is incorporated as a reset mechanism for automatically returning the operating device to the initial position, it is difficult to move the operating body relatively even if a thick O-ring with a large amount of elastic deformation is used. Large slippage, so there is an area where a wide operating body can not be used for sliding operation (operating area)

In addition, in the conventional example in which a wire spring is incorporated as a reset mechanism for automatically returning the operating body to the initial position, since the reaction force of the wire spring varies greatly depending on the direction in which the operating body is slid, there is a problem with the operation. The problem that the force has a large deviation due to different sliding directions
