Surface contact card holder

1. A holder for holding a surface contact card, comprising:

a main body forming a receiving portion, the receiving portion being configured for receiving the surface contact card therein;

a latching portion carried on the main body, the latching portion being adjacent to the receiving portion; and

an elastic element rotatably hinged to the latching portion and configured for selectably resisting the surface contact card, the elastic element including two bending portions and a middle portion connected to each other, and each bending portion having a resisting end radially extending from a distal end thereof.

2. The holder as claimed in claim 1 , wherein the receiving portion includes a projection block, the projection block is a beam protruding on the main body and the projection block partially surrounds a space configured for receiving the surface contact card.

3. The holder as claimed in claim 2 , wherein the projection block includes two end portions and a connecting portion, each end portion extends from a distal end of the connecting portion, and the two end portions and the connecting portion co-operatively form a rectangular-bracket-shaped area with an open side.

4. The bolder as claimed in claim 1 , wherein the latching portion includes at least one notch and at least one post, the at least one notch is defined on the main body at a position opposite to the receiving portion, and the at least one post extends from a sidewall of the at least one notch.

5. The holder as claimed in claim 4 , wherein the at least one post perpendicularly extends from the sidewall, the at least one post is substantially cylindrical, the at least one past is coplanar with one side of the main body, and the other side of the at least one post is spaced apart from the other side of the main body.

6. The holder as claimed in claim 5 , wherein the latching portion further comprises at least one protrusion, and each protrusion is positioned adjacent to each post.

7. A holder for holding a surface contact card in a portable electronic device, the electronic device having a device body, the holder comprising:

a receiving portion formed on the device body and being configured for receiving the surface contact card, the receiving portion being a projection block, the projection block including two end portions and a connecting portion, each end portion perpendicularly extending from a distal end of the connecting portion, thus co-operatively forming a rectangular-bracket-shaped area; and

an elastic element rotatably hinged to the device body and configured for pressing on the surface contact card, the elastic element including two bending portions and a middle portion connected to each other, the middle portion pressing an open side of the rectangular-bracket-shaped area, and the two bending portions being rotatably attached to the device body.

8. The holder as claimed in claim 7 , wherein at least one bump extends from the connecting portion of the projection block so as to limit the surface contact card to selectably moving one of upward and downward.

9. The holder as claimed in claim 8 , wherein two bumps are symmetrically fanned on the connecting portion.

10. The holder as claimed in claim 7 , further comprising a latch portion, wherein the latch portion includes two knobs and two bulges, the elastic element further comprises two resisting ends, respectively, tangentially extending from a corresponding bending portion, each bending portion is placed around a corresponding knob, and each resisting end resists a corresponding bulge.

11. A portable electronic device comprising:

a device body forming a receiving portion, the receiving portion being configured for receiving a surface contact card, the receiving portion partially enclosing the surface contact card so as to keep the contact surface card in the receiving portion, the receiving portion comprising a projection block, the projection block including two end portions and a connecting portion, and each end portion extending from a distal end of the connecting portion; and

a control element rotatably hinged on the opposite side of the receiving portion and configured for selectably blocking the surface contact card from exiting from the receiving portion, the control element being an elastic element, the elastic element including two bending portions and a middle portion connected each other, the middle portion pressing the receiving portion, and the two bending portions being rotatably attached to the device body.

12. The portable electronic device as claimed in claim 11 , further comprising a latch portion, wherein the latch portion includes two cylinders extending from the device body, and each bending portion is placed around a corresponding cylinder.
