Abstract: A support structure of a digital device contains a holding unit including a tray member to place the digital device, the tray member including a circular hole disposed on a central portion thereof, a plurality of retaining recesses arranged around the hole on a front end of the tray member; an angle adjusting mechanism including a circular tab and a number of resilient locking devices attached around a peripheral side of the circular tab, such that the tab is fitted in the hole of the tray member of the holding unit so that the holding unit is rotated vertically or horizontally by using the angle adjusting mechanism; a supporting unit axially with the angle adjusting mechanism.

Abstract: A notebook computer support seat which can be conveniently folded and carried is the support seat which is made by lightweight but stiff aluminum plates pivoted by hinges. A support arm on a base plate can be reversely inserted into an insertion hole of a front plate, projected support pieces can support the notebook computer, and insertion blocks at a tail end of a support plate or another coaxial inner support plate can be inserted into any set of insertion holes of the base plate according to an angle required by a user. The present invention can be folded into a plane shape, to facilitate being placed in a suitcase with the notebook computer, for carrying.
