Patent number: 8319604Abstract: An electric release fastening device for a thin-profile space has a fingerprint identifier, a micro drive motor, a change gear set, an electric controller, an electric battery, a moveable fastening cassette, a fastening cassette control unit and a locking locator. When the fingerprint identifier reads the correct identification information, the micro drive motor is ordered by the electric controller to drive the change gear set, and then change the position of the fastening cassette control unit. This switches the positioning or release state between the moveable fastening cassette and the locking locator, and controls or electrically releases the product cover. With this configuration, the electric release fastening device can be assembled into thin-profile spaces with improved applicability.Type: GrantFiled: February 1, 2010Date of Patent: November 27, 2012Inventors: Ping-Hsun Weng, Chun-Sung Cheng, Chih-Lung Peng
