Abstract: Disclosed is a recording and/or reproducing apparatus, including: a chassis having an insertion/ejection port; a recording medium tray for holding a recording medium, which transfers it into a recording and/or reproduction position where recording and/or reproduction of data onto/from the recording medium are performed or transfers it to an ejected position outside the chassis; a panel in which the insertion/ejection port for the recording medium tray is formed and which is provided on one side surface of the main body of the apparatus; a lid body which can close the insertion/ejection port; and an elastic member provided between the lid body and recording medium tray. In a state where the insertion/ejection port is closed by the lid body, the elastic member pulls the lid body toward the inside of the chassis to allow the lid body to be brought into pressure contact with the panel by an elastic force of the elastic member to thereby reduce the size of a gap between the lid body and panel.
