An apparatus is provided comprising: a record and/or playback units having a first circuit board provided with a grounding potential unit; a cover body pivotably mounted to the record and/or playback unit and including a shield member connected to the grounding potential unit and a second circuit board connected to the first circuit board; a holder made of a metallic material and arranged to travel between the location for loading a recording medium into the record and/or playback unit and the location spaced away from the record and/or playback unit as the cover body is pivotably moved, and a grounding member made of a metallic material, provided with an engaging portion for engagement with the shield member and a contact for coming into direct contact with the holder, and connected to the shield member to urge the cover body in a direction of the holder pivotably turning. Since the shield member is connected to the grounding member, the circuit board remains connected to the ground thus preventing the apparatus from being statically charged.
