Intelligent Mediation in Active Knowledge Mining: Goals and General Description

A protecting device for an electronic peripheral device, the protecting device having a front cover, mounted on a front surface of the housing for the electronic peripheral device and a door which is opened or closed depending on whether the peripheral equipment needs to be used. The door is pivotally connected to both sides of the front cover such that it protects the peripheral equipment from being damaged. A controlling device is are provided for controlling the opening speed and opening degree of the door. The controlling device includes a rotating shaft inwardly disposed in a lower end of the front cover, both ends of which pass through both sides of the front cover and are inserted into each concavity respectively formed on leg portions of the door; a pair of brakes mounted opposite to each other on the rotating shaft, the brakes contacting a rib formed on the rotating shaft and having guide notches formed on each side thereof so that the rib can move up and down in accordance with the rotation of the rotating shaft; and elastic members disposed respectively between lateral walls formed on the inner surface of the front cover and outside faces of the brakes such that the biasing force of the elastic members is applied to the brakes.
