The present invention generally relates to an injector/ejector (in/ejector) and shelf structure grounded to a frame ground of a card, in which electromagnetic and electric waves generated in an electric or electronic device can be conducted outside. More specifically, the present invention comprises: a shelf having a frame, a guide rail and a guide supporter, wherein the frame and the guide rail are established at a given spacing in front and rear portions of upper and lower ends thereof, respectively, in order to provide a framework, and wherein the guide supporter has a common conductivity formed in an inside of both upper and lower parts thereof; a card including a frame ground and a stiffener, wherein the frame ground having conductivity is formed on upper and lower parts thereof, and wherein the stiffener having a rectangular shape is formed on a front part thereof, and wherein the card is mounted on the shelf; and an in/ejector for fixing the card on the shelf, wherein said in/ejector is coupled to upper and lower parts of the stiffener and is grounded to the guide supporter and the frame ground. According to the present invention, communication interference caused by unnecessary electromagnetic waves generated in the electronic device, electric wave of other devices and an external electric wave can be reduced, thereby mitigating the loss of lives and property damage resulting from incorrect operations. Additionally, in conducting radiation test of EMI and static electricity radiation test among the adaptability test of electromagnetic wave for systems, electromagnetic waves can be reduced significantly so that the device can operate normally under static electricity when the frame grounds on various cards are conducted outside.

The invention claimed is: 1. An in/ejector and shelf structure grounded to a frame ground of a card, said structure comprising: a shelf having a guide supporter, wherein the guide supporter has a common conductivity formed in an inside of both upper and lower parts of the shelf, and wherein the guide supporter comprises an elastic conductive element; a card including a frame ground and a stiffener, wherein the frame ground having conductivity is formed on upper and lower parts of the card, and wherein the stiffener having a rectangular shape is formed on a front part of the card, and wherein the card is mounted on the shelf; and an in/ejector for fixing the card on the shelf, wherein the in/ejector is coupled to upper and lower parts of the stiffener and is grounded to the frame ground, and grounded to the guide supporter via the elastic conductive element. 2. The in/ejector and shelf structure grounded to the frame ground of the card according to claim 1, wherein the elastic conductive element comprises a finger strip having elasticity formed on a guide groove and shaped as 'c', the finger strip fixing the in/ejector on the guide groove and causing the in/ejector to be grounded, and wherein the guide supporter further comprises: a body formed on the upper and lower ends of the shelf and having the guide groove, the guide groove causing the frame ground of the card embedded on the shelf and the in/ejector to be grounded; and a fixing protrusion formed on one side of the body having a prescribed size, wherein the in/ejector is coupled to the fixing protrusion. 3. The in/ejector and shelf structure grounded to the frame ground of the card according to claim 2, wherein the in/ejector comprises: a locker having a lever formed on the upper part of the locker, wherein the lever causes the card to be vertically self-erectable on the shelf; a body mounted on the lower part of the locker having a fixing groove shaped as a groove on the lower part of the body, wherein the body is fixed to the guide supporter having the fixing protrusion; and a base established on one side of the lower part of the body having a coupling protrusion on the lower part of the base, wherein the base causes the guide supporter having the finger strip to be grounded.
