Multi-directional slide input device for a portable terminal

Abstract

The invention relates to a multi-directional slide input device for a portable terminal, which comprises: a base, which is mounted on the terminal and includes a rectangular-shaped operation surface and a wall formed along the frame of the operation surface, the wall having at least four stationary contact points therein; an X-axis moving stage, which is provided with an X-axis sliding portion formed in a protruding manner on the upper and lower sides of the wall to move in the horizontal direction while being seated on the operation surface, and with a Y-axis moving guide formed in a protruding manner inside the wall on both lateral sides thereof; a Y-axis moving stage, which has an installation surface to install at least one key input means thereon, the installation surface having a wall formed along the frame thereof, and is provided with a Y-axis sliding portion to be coupled with the Y-axis moving guide so as to move vertically within an opening and with an actuation operating portion arranged, on the outside of the wall, at a distance, the actuation operating portion having a multiplicity of actuation contact points connected to the key input means; and a circuit board, which is mounted on the installation surface of the Y-axis moving stage and has a keypad contact point. It is an advantage of the invention that various electric actions are executed by the operation of the stationary and moving contact points through the sliding motion from the central point of the Y-axis moving stage towards a target direction and the return motion towards the central point, and by the operation of the key input means.

Description

technical field [0001] The present invention relates to multi-directional input devices used in game machines, mobile phones and the like. More particularly, the present invention relates to a multi-directional slide input device for a portable terminal capable of inputting a predetermined signal through a slide operation. Background technique [0002] Several types of slide input devices are provided, which are configured to perform switching operations, mode switching operations, and other electrical operations by performing contact and separation operations of contacts in a manner that is aimed at mounting in a base, housing, etc. on a terminal. The included static contact slides and moves the slide bar equipped with the movable contact. [0003] However, in existing slide input devices, a switch having a slide bar configured to slide and move in four directions of up, down, left, and right requires a large number of components. In particular, with the tendency to signi...

AI Technical Summary

Problems solved by technology

It is very difficult to use fingers to accurately distinguish between 12 directions or 16 directions, and this method is inefficient

[0011] An input device using 12 to 16 directions has a problem that the rate of missing type increases when characters and numbers are input

In this way, there is a disadvantage that the length and width of the portable terminal increase because the sliding stroke for signal input is inevitably lengthened.

Accordingly, there is a problem that the processing speed of the input signal is relatively low since the signal of the combined static contact has to be processed

[0014] The third conventional technique, Korean Patent Registration No. 0477775 (hereinafter referred to as "the third conventional patent") adopts a method of operating eight directions independently, but has the disadvantage that the radius is very wide when operating the length, And the height and size are not suitable for use in portable terminals

In addition, there is a burden on assembly and product costs due to the large number of components required

Furthermore, the third conventional patent does not have a structure capable of including a plurality of keypads at all
