Digital processing unit that can prevent deflections and typing error with applying dual-magnet and bearing ball

The finger is applied to the sustain be how a double magnet and bearing in the ball with great force the deflection prevention after the slider unit returns operated according to the pushing direction, while operating the horizontal force in a very fine force the fingers can slide on the slide input device the slider portion effective homing method is disclosed in the slide input device. As an input system such that a user input on the control command according to the movement direction, A base provided with a four direction detecting signal for North, South, East and West directions for position detection according to the horizontal movement; By a user operation by which to translate the slider to the horizontal plane of the base; A frame in which the slider is supported for translation relative to the base; After the user of the operating force is removed the added slider magnets provided to the slider unit to return to the initial position; After the user of the operating force is removed the added slider magnets provided to the base unit to return to the initial position; Located between the base and the slider, and moved along the parallel movement of the slider, which reduces the resistance to movement in translation of the slider ball bearings; the A slide input device, characterized in that configured. According to the present invention, the OTA type of the character input is reduced with a simple structure, it is possible to effectively prevent the slider portion of deflection in a small operating force.
