OPENING AND CLOSING DEVICE FOR A PORTABLE TERMINAL

摘要

A device for opening and closing a portable terminal has first and second plates. A link module and a slider movably connect the plates. The link module is slidable between the plates. The slider has a rotation shaft fixedly coupled with the second plate and rotatable in the slider. A power module is affixed to the first plate. The slider is slidable along a straight guide section of the first plate to slide the rotation shaft selectively into or out of contact with the power module. The power module is configured to resiliently bias a roller of the power module against the slider rotation shaft to control rotation of the rotation shaft relative to the first plate.
