Problems solved by technology

[0013] However, the peripheral movable electrode portion 105b formed on the movable electrode plate 105, compared with the peripheral movable electrode portion 105b formed in the vicinity of the connecting portion 105d, has a peripheral electrode portion formed in the vicinity of the connecting portion 105d. The reaction force of the movable electrode part 105b becomes large, and there is a problem of unevenness in the circumferential direction in the radially outward input operation feeling.
[0014] In addition, since the casing 101 has the guide wall 101b through which the movable electrode plate 105 and the operation member 107 are inserted to restrict the arrangement position, it is difficult to thin the guide wall 101b in the vertical direction.

no. 1 approach

[0156] The multi-directional input device 1 of the first embodiment of the present invention will be as figure 1 The parts of the structure broken down as shown are Figure 8 and Figure 9 Comes assembled as shown. The various parts of the structure of the multi-directional input device 1 of the present embodiment are in order from bottom to top, that is, in accordance with: the housing 2, the fixed contacts 3 for the periphery, the movable electrodes 4 for the periphery, and the common electrode 5 for the periphery, etc. Components for inputting directions, fixed contacts 6 for the center, movable electrodes 7 for the center, and common electrodes 8 for the center, and other components for inputting in the pressing direction to the center, the operating member 9, the cover 13, and the reset member 14 and the order of the restricting member 15 will be described.

[0157] Such as figure 2 As shown, the casing 2 of the multi-directional input device 1 is formed in a thin b...

no. 2 approach

[0185] Such as Figure 13 As shown, in the multidirectional input device 1a of the second embodiment, in addition to the guide wall 2b of the casing 2, the movable electrode 4 for the periphery, the movable electrode 7 for the center, and the common electrode 8 for the center, the multidirectional The individual components in the input device 1a are the same as those used in the multi-directional input device 1 of the first embodiment. here as Figure 13 As shown, the movable electrode 4 for the periphery and the movable electrode 7 for the center used in the second embodiment communicate with each other via the support portion 4g and are integrally formed. Therefore, in the second embodiment, the center common electrode 8 is not provided and excluded. In addition, a slit 2k is provided in a part of the annular guide wall 2b through which a support portion 4g that connects and supports the movable electrode 4 for the periphery and the movable electrode 7 for the center passe...

no. 3 approach

[0189] Such as Figure 14 As shown, the multi-directional input device 1b of the third embodiment is formed by adding the following components to the multi-directional input device 1 of the first embodiment in order to apply secondary input to the input operation in the circumferential direction. That is, if Figure 14 As shown, the multi-directional input device 1b of the third embodiment is the same as that of the first embodiment, and the casing 2 has: fixed contacts 3 for the periphery, movable electrodes 4 for the periphery, common electrodes 5 for the periphery, etc. Each part for input to the outside, fixed contact 6 for the center, movable electrode 7 for the center, common electrode 8 for the center, etc., each part for input in the push direction in the center, the operating part 9, the cover 13, the reset The member 14 and the restricting member 15 are provided with a second peripheral movable electrode 16 and a second peripheral common electrode 17 in the vicinity...

Abstract

Provided is a multidirectional input device capable of providing an excellent operation feeling by reducing dispersion of operation force in an operation direction. The multidirectional input device 1 is provided with: a plurality of annularly-arranged fixed contacts 3 for a periphery; an annularly-formed flat moving electrode 4 for the periphery formed by having projecting parts 4a to be held which are extended to the inside or the outside of its circumference and generating reactive force against pressing force generated on the circumference; a casing 2 for holding the fixed contacts 3 for the periphery and the moving electrode 4 for the periphery with a predetermined distance while facing to the annularly-arranged fixed contacts 3 for the periphery; and an operation member 9 arranged above the moving electrodes for the periphery and having a pressing part 12a for the periphery for pressing the moving electrode 4 for the periphery.

Description

technical field [0001] The present invention relates to a multi-directional input device, and more particularly to a multi-directional input device used for directional input operations of various electronic devices as a direction key for a portable phone, a portable music player, a controller for a game machine, and the like. Background technique [0002] Generally, the multi-directional input device can perform key input in multiple directions such as up, down, left, and right by pressing or pushing down the direction key or the rod-shaped input key. [0003] Such as Figure 24 to Figure 26 As shown, an example of a conventional multi-directional input device is formed. In this conventional multi-directional input device 100 , various structural parts are disposed inside a rectangular box-shaped housing 101 , and the topmost opening of the housing 101 is closed by a cover 112 . [0004] Each structural part will be described in order from bottom to top, that is, in the or...
