The electronic apparatus includes a hinge mechanism connecting a main body chassis and a display chassis; a movable plate provided on a top surface of the main body chassis and is turnable in a direction in which its rear end moves up and down around a rotating shaft part provided at its front end; a drive mechanism that turns the movable plate in conjunction with a turning operation between the main body chassis and the display chassis by the hinge mechanism; and a release mechanism that releases an interlocking state of the turning operation and the movable plate by the drive mechanism to allow the movable plate to turn in a downward direction when the movable plate of which the rear end is located at a raised position receives a predetermined external force in the downward direction. ## Claims ### Claim 1 An electronic apparatus comprising: a first chassis having a keyboard device; a second chassis having a display; a movable plate disposed between said first and second chassis; a hinge mechanism having a hinge chassis that connects said first chassis, said second chassis, and said movable plate to each other, wherein said hinge mechanism includes a drive mechanism that turns said movable plate in conjunction with a turning operation between said first chassis and said second chassis by said hinge mechanism; and a release mechanism that releases an interlocking state of said turning operation and said movable plate by said drive mechanism to allow said movable plate to turn in a downward direction when said movable plate of which a rear end is located at a raised position receives a predetermined external force in said downward direction. ### Claim 2 (depends on 1) The electronic apparatus of claim 1, wherein said hinge mechanism includes a hinge chassis provided to extend between said first chassis and said second chassis; and a first hinge shaft that relatively rotatably connects said first chassis and said hinge chassis. ### Claim 3 (depends on 1) The electronic apparatus of claim 1, wherein said drive mechanism includes a turning shaft provided coaxially with a first hinge shaft; an arm member of which one end is turnably connected to a hinge chassis via said turning shaft; and a drive shaft that relatively rotatably connects another end of said arm member and said rear end of said movable plate. ### Claim 4 (depends on 3) The electronic apparatus of claim 3, wherein said hinge chassis includes a housing part that retractably houses said arm member, and said arm member is housed in said housing part at said maximum turning position. ### Claim 5 An electronic apparatus, comprising: a first chassis; a second chassis; a hinge mechanism connecting said first and said second chassis; a movable plate provided on a top surface of said first chassis, said movable plate being turnable in a direction in which its rear end moves up and down around a rotating shaft part provided at its front end; a drive mechanism that turns said movable plate in conjunction with a turning operation between said first chassis and said second chassis by said hinge mechanism, wherein said drive mechanism includes a turning shaft provided coaxially with a first hinge shaft; an arm member of which one end is turnably connected to an hinge chassis via said turning shaft; and a drive shaft that relatively rotatably connects another end of said arm member and said rear end of said movable plate; and a release mechanism that releases an interlocking state of said turning operation and said movable plate by said drive mechanism to allow said movable plate to turn in a downward direction when said movable plate of which said rear end is located at a raised position receives a predetermined external force in said downward direction. ### Claim 6 (depends on 5) The electronic apparatus of claim 5, wherein said release mechanism includes a holding member that holds and arm member at a maximum turning position at which said other end moves towards said hinge chassis at a maximum and releases a holding state of said arm member at said maximum turning position to allow said arm member to turn in a direction in which said other end is away from said hinge chassis when said movable plate receives said predetermined external force. ### Claim 7 (depends on 6) The electronic apparatus of claim 6, wherein said holding member includes a first magnet that is provided in one of said hinge chassis and said arm member; and a second magnet or an adsorbed body that is provided in another of said hinge chassis and said arm member and can be adsorbed to said first magnet. ### Claim 8 (depends on 6) The electronic apparatus of claim 6, wherein said holding member includes an elastic member that biases said arm member in a direction in which said arm member is turned towards said maximum turning position. ### Claim 9 (depends on 5) The electronic apparatus of claim 5, wherein said hinge chassis includes a housing part that retractably houses said arm member, and said arm member is housed in said housing part at said maximum turning position. ### Claim 10 (depends on 5) The electronic apparatus of claim 5, wherein said rotating shaft part includes a connecting shaft that relatively rotatably connects said front end of said movable plate and said first chassis; and a slide support that supports said connecting shaft to be slidable along said top surface of said first chassis. ### Claim 11 (depends on 5) The electronic apparatus of claim 5, wherein a display is provided on a top surface of said movable plate.
