Electronic apparatus having a sub display

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.
