A mounting apparatus for securing expansion cards (30 ) with cover plates (34) to a computer includes a chassis ( 10), a bracket (40) and a mounting member (50). The chassis includes a rear panel (14). The bracket includes a pair of guiding portions (44) for slidably receiving the mounting member. Each guiding portion defines a locating aperture (446) therein. The mounting member includes a main portion (52) and a pair of operating members (59). The main portion includes a base (58 ), and first and second sidewalls (53, 54). The second sidewall includes a pair of mounting holes (546). Each operating member includes a protrusion (596) and a fastening portion (598). When the operating members are rotated, the fastening portions engage in the locating apertures, the protrusions engage in the mounting holes, the main portion thereby urges the cover plates. Thus the expansion cards are mounted in the chassis.

What is claimed is: 1. A mounting apparatus for securing a plurality of expansion cards with cover plates to a computer, the mounting apparatus comprising: a chassis comprising a rear panel, the rear panel having a mounting frame; a bracket arranged at the rear panel, comprising a pair of guiding portions, a locating aperture defined in each of the guiding portions; and a mounting member slidably received in the guiding portions of the bracket, the mounting member comprising a main portion and a pair of operating members, the main portion comprising a base, and first and second sidewalls extending upwardly from two opposite sides of the base, a pair of mounting holes defined in one of the sidewalls, the operating members pivotally secured between the first and second sidewall, each of the operating members having a protrusion and a fastening portion; wherein when the cover plates are attached to the mounting frame of the rear panel of the chassis, the mounting member is driven downwardly toward the cover plates until the base of the mounting member presses the cover plates, and the operating members are rotated until the fastening portions engage in corresponding locating apertures of the guiding portions of the bracket, and wherein when the protrusions of the operating members engage in corresponding mounting holes of the main portion of the mounting member, the expansion cards are thereby mounted on the chassis. 2. The mounting apparatus as described in claim 1, wherein the bracket further comprises a main plate, and the guiding portions are bent from two opposite sides of the main plate. 3. The mounting apparatus as described in claim 2, wherein each of the guiding portions of the bracket has a resilient tab above the locating aperture, the tab has a locating portion extending inwardly at a distal end thereof for abutting the mounting member. 4. The mounting apparatus as described in claim 2, wherein two guiding slots are defined in the main plate of the bracket, and the second sidewall of the mounting member comprises two guiding posts slidably received in the guiding slots. 5. The mounting apparatus as described in claim 2, wherein a retaining portion is formed on the main plate of the bracket, and a hitching tab is formed on the second sidewall of the mounting member to engage with the retaining portion. 6. The mounting apparatus as described in claim 1, wherein the main portion of the mounting member further comprises a pair of third sidewalls, each of the third sidewalls defines a through aperture corresponding to the locating aperture of the bracket and a locating hole above the through aperture. 7. The mounting apparatus as described in claim 1, wherein an operating portion is projected from the first sidewall of the main portion of the mounting member, and a plurality of fingers are extended from a bottom portion of the first sidewall. 8. The mounting apparatus as described in claim 1, wherein a plurality of resilient tongues are formed on the base of the main portion of the mounting member for pressing the cover plates. 9. A mounting apparatus for securing expansion cards with cover plates to a computer, the mounting comprising: a chassis comprising a rear panel, the rear panel comprising a mounting frame and a pair of guiding portions above the mounting frame, each of the guiding portions defining a locating aperture therein; and a mounting member slidably received in the guiding portions of the rear panel, the mounting member comprising a main portion and a pair of operating members, the main portion comprising a base, and first and second sidewalls extending upwardly from two opposite sides of the base, the operating members pivotally secured between the first and second sidewalls, each of the operating members having a fastening portion, an engaging means disposed at the mounting member for retaining the operating members; wherein when the cover plates are attached to the mounting frame of the rear panel of the chassis, the mounting member is driven downwardly toward the cover plates until the base of the mounting member presses the cover plates, and the operating members are rotated until the fastening portions engage in corresponding locating apertures of the guiding portions, and wherein when the operating members are secured by the engaging means, the expansion cards are thereby mounted to the chassis. 10. The mounting apparatus as described in claim 9, wherein each of the guiding portions of the rear panel has a resilient tab above the locating aperture, and the tab has a locating portion extending inwardly at a distal end thereof for abutting the mounting member. 11. The mounting apparatus as described in claim 9, wherein two guiding slots are defined in rear panel between the guiding portions, and the second sidewall of the mounting member comprises two guiding posts slidably received in the guiding slots. 12. The mounting apparatus as described in claim 9, wherein a retaining portion is formed on the rear panel between the guiding portions, and a hitching tab is formed on the second sidewall of the mounting member to engage with the retaining portion. 13. The mounting apparatus as described in claim 9, wherein the main portion of the mounting member further comprises a pair of third sidewalls, each of the third sidewalls defines a through aperture corresponding to the locating aperture of the guiding portion and a locating hole above the through aperture. 14. The mounting apparatus as described in claim 9, wherein an operating portion is projected from the first sidewall of the main portion of the mounting member, and a plurality of fingers are extended from a bottom portion of the first sidewall. 15. The mounting apparatus as described in claim 9, wherein the engaging means of the mounting member comprises a pair of the protrusions which are respectively formed at free ends of the operating members, and a pair of the mounting holes defined in one of the sidewalls for engagingly receiving the protrusions. 16. The mounting apparatus as described in claim 9, wherein a plurality of resilient tongues are formed on the base of the main portion of the mounting member for pressing the cover plates. 17. A mounting apparatus assembly comprising: a plurality of expansion cards with cover plates thereof; a chassis comprising a rear panel with a bent portion thereon; a bracket mounted on the rear panel above said bent portion; and a mounting member slidably, in a vertical direction, received in the bracket, the mounting member comprising a main portion and at least one operating member, the main portion comprising a base to which said one operating member is pivotally mounted; wherein when the cover plates are attached to the rear panel, the mounting member is driven downwardly toward the cover plates until the base of the mounting member contacts the cover plates, and the operating member is rotated until one end of the operating member abuts against one portion of the bracket to result in further downward movement of the mounting member by a reaction force derived from confrontation between the mounting member and the bracket, and such rotation terminates when said operating member reaches a final locking position where said reaction force is maximum, wherein the cover plates are sandwiched between the bent portion and the mounting member in the vertical direction.
