Claims (1)

[Claims for Utility Model Registration] 1. A loading device that includes a tray for placing an external memory thereon and a cover for covering the tray, each of which is supported on a frame so as to be openable and closable. a spring for biasing the tray in a direction in which the tray opens; and a spring provided in association with the cover to bias the tray in a neutral state between a closed state and a maximum open state. The biasing direction is reversed, and when the opening degree of the cover is smaller than the neutral state, the cover is biased in the direction to close it, and when the opening degree of the cover is larger than the neutral state, the cover is biased in the direction to open it. A loading device for an external memory, comprising: a reversing spring biasing the cover so that the maximum opening degree of the cover is larger than the maximum opening degree of the tray. 2 an electrode provided on the tray; a spring for biasing the tray is made of a conductive material and electrically connected to the electrode; and the spring is electrically connected to a ground terminal; when placed on the tray, a conductive member of the external memory contacts the electrode,
The external memory loading device according to claim 1, wherein static electricity is thereby caused to reach the ground terminal through the electrode and the spring. 3. The external memory loading device according to claim 1 or 2, wherein the tray and the cover are supported coaxially with respect to the frame.
