A sliding opening and closing device for electronic device

The present invention relates to a device to open and close by sliding the cover in the case that excessive invention to form an opening of the electronic apparatus. Most electronic devices are formed on the case cover portion for replacing the battery or other parts, and the opening and closing takes place by the sliding of the left and right. The group's when the cover is separated from the body that does not readily it is common to form a separate cover or a protrusion on the installation of the elastic members. However, the structure has a high installation possibility of occurrence of the failure to the complexity of the elastic member is formed of the projections there is a problem in that this restriction applies to the situation does not help much on ease of opening and closing of the cover. In order to overcome this problem the present invention, the force that by placing the one side and slide the permanent magnet of the same polarity as the point at which the cover is separated in to place a permanent magnet on a side of the cover to the movement of the electronic device case slide of the permanent magnet so that the cover is pushed upward by the sides and at the time that the cover is mounted the other polarity is disposed has a characteristic such that the cover is easy to mount. This change of a simple structure on a side in the electronic device case by just the effect that the opening and closing of the cover easily.
