  • Patent number: 8355764
    Abstract: A sliding module for a slide-type portable communication apparatus including a main body and a sliding body which slides on the main body along a sliding distance provided from a start position to an end position. The sliding module includes a fixed plate engaged with the main body, a moving plate being engaged with the sliding body and sliding along the sliding distance. A sliding module is provided between the fixed plate and the moving plate and provides a dead point position between the start position and a center position of the sliding distance, or closer to the start position to slide the moving plate. The dead position prevents the accidental closing of the sliding body and loss of communication if a user's hand slips during the opening of the sliding body to expose a portion of the main body.
