The case includes a first layer and a second layer. The second layer is connected to the first layer by the edges. A receiving space is formed between the first and second layers for receiving the portable electronic device. The second layer is provided with a base portion, a main supporting portion, two side supporting portions and two remaining portions are formed on the second layer. The two side supporting portions and the remaining portions are symmetrically positioned at two sides of the main supporting portion. When the case is folded up as a support, the main supporting portion is angled with the base portion. The remaining portions are stacked on the base portion. The side supporting portions are perpendicular to the remaining portions and the main supporting portion. ## Claims ### Claim 1 A multifunctional case for receiving or supporting a portable electronic device, comprising: a first layer; and a second layer connected to the first layer at edges, a receiving space formed between the first and second layers for receiving the portable electronic device; the second layer provided with a base portion, a main supporting portion, two side supporting portions and two retaining portions; the two side supporting portions and the retaining portions symmetrically positioned at two sides of the main supporting portion; when the case is folded up as a support, the first layer and the second are together folded, the retaining portions are stacked on the base portion, and the side supporting portions are perpendicular to the retaining portions and the main supporting portion, and the main supporting portion is at an acute angle with the base portion; wherein the base portion includes a baseline, the baseline includes a middle portion and two end portions, and the main supporting portion includes an end edge adjacent to and parallel with the middle portion, the retaining portion includes a first edge adjacent to and parallel with the end portion of the baseline; a first folding area is formed between the base portion and the main supporting portion; a second folding area is formed between each side supporting portion and the main supporting portion; and a third folding area is formed between each pair of the side supporting portion and the retaining portion. ### Claim 2 (depends on 1) The multifunctional case as claimed in claim 1, wherein an opening is formed to communicate to the receiving space, allowing the portable electronic device to be inserted into the receiving space. ### Claim 3 (depends on 1) The multifunctional case as claimed in claim 1, wherein the retaining portion further includes a second edge, and the side supporting portion includes a sloping edge adjacent to and parallel with the second edge. ### Claim 4 (depends on 3) The multifunctional case as claimed in claim 3, wherein the side supporting portion further includes a bottom edge, and the main supporting portion further includes a side edge adjacent to and parallel with the bottom edge. ### Claim 5 (depends on 4) The multifunctional case as claimed in claim 4, wherein an angle between the sloping edge and the bottom edge is selected from 30 degree to 60 degree. ### Claim 6 (depends on 2) The multifunctional case as claimed in claim 2, wherein a locking member is formed on the second layer, positioned adjacent to the base portion. ### Claim 7 (depends on 6) The multifunctional case as claimed in claim 6, wherein the locking member includes a head, and a slot is formed between the head and the second layer to lock one end of the portable electronic device. ### Claim 8 (depends on 7) The multifunctional case as claimed in claim 7, wherein the locking member includes a plurality of parallel bars protruding from the second layer. ### Claim 9 (depends on 2) The multifunctional case as claimed in claim 2, further comprising a flexible closing piece to close the opening. ### Claim 10 (depends on 9) The multifunctional case as claimed in claim 9, wherein the closing piece extends from the second layer adjacent to the opening. ### Claim 11 (depends on 1) The multifunctional case as claimed in claim 1, wherein the material of the first and the second layers is selected one of the groups of fiber, cotton, vinyl, thermoplastics. ### Claim 12 A multifunctional case for receiving or supporting a portable electronic device, comprising: a first layer; a second layer connected to the first layer at edges, a receiving space formed between the first and second layers for receiving the portable electronic device; and a portion including a first folding area, two second folding areas and two third folding areas symmetrically positioned relative to a center line of the second layer; the first folding area being across the portion; the first folding area including a middle portion and two end portions; the two second folding areas parallel to each other and perpendicularly communicating with the middle portion of the first folding area; the two third folding areas communicating to the first folding area and the two second folding areas and positioned between the end portion and the second folding areas, each third folding area being at an acute angle with a corresponding second folding area; wherein when the case is folded up as a support, the two third folding areas are folded up and are at a same plane with the first folding area, the two second folding areas are folded up and are at the acute angle with the plane of the first folding area and the two third folding area. ### Claim 13 (depends on 12) The multifunctional case as claimed in claim 12, wherein an opening is formed to communicate to the receiving space, allowing the portable electronic to be inserted into the receiving space. ### Claim 14 (depends on 13) The multifunctional case as claimed in claim 13, wherein a locking member is formed on the second layer. ### Claim 15 (depends on 14) The multifunctional case as claimed in claim 14, wherein the locking member includes a head, and a slot is formed between the head and the second layer to lock one end of the portable electronic device.
