Patent ID: 8494603

Claim:
An operation device for controlling sliding cover of portable electronic product, comprising a body and a sliding cover slidably and linearly connected to the body, the operation device comprising: a first magnetic member fixed to a first position of the sliding cover and the first magnetic member having a first magnetic polarity; a second magnetic member fixed to a second position of the sliding cover, the first position being located at a distance from the second position, the second magnetic member having a first magnetic polarity; a transmission unit connected to the body and having a first part, a second part and a third part, the third part threadedly connected between the first and second parts; an operation unit connected to the first part; a fixed part fixed to the second part; a third magnetic member connected to the fixed part and the second part and having a first magnetic polarity and a second magnetic polarity, the first and second polarities of the third magnetic member being located corresponding to the first magnetic polarity of the first magnetic member and the first magnetic polarity of the second magnetic member, the three respective first magnetic polarities being magnetically repulsive to each other, the second magnetic polarity of the third magnetic member being magnetically attracted to the three respective first magnetic polarities, and the transmission unit being activated by operation of the operation unit and the third magnetic member being pivoted by the transmission unit so that positions of the first and second magnetic polarities of the third magnetic member are switched.
