1. An electronic apparatus comprising:
a first chassis;
a second chassis which is adjacent to the first chassis;
a hinge device which so connects the first chassis and the second chassis as to be rotationally movable relative to each other between a first posture that the first chassis and the second chassis are so folded as to mutually overlap in a surface normal direction and a second posture that the first chassis and the second chassis are mutually arrayed in a direction which is vertical to the surface normal direction; and
a display which is so installed as to range from the first chassis to the second chassis and has a folding region which is folded in accordance with relative rotational movement of the first chassis and the second chassis, wherein
the hinge device has
a hinge main body which extends along mutually adjacent ends of the first chassis and the second chassis, is so arranged as to stride over the mutually adjacent ends and supports a rear face of the display with its front face,
a first support plate which is adjacent to a first edge of the hinge main body which is located on the first chassis side, is installed to be movable relative to the first edge and supports the rear face of the display with its front face and
a second support plate which is adjacent to a second edge of the hinge main body which is located on the second chassis side, is installed to be movable relative to the second edge and supports the rear face of the display with its front face,
the hinge main body has
a first locking strip which protrudes toward the first support plate side and is locked on the rear face side of the first support plate at the time of taking the second posture and
a second locking strip which protrudes toward the second support plate side and is locked on the rear face side of the second support plate at the time of taking the second posture,
the first support plate has a first plate-side locking strip which protrudes toward the hinge main body side and is locked on the rear face side of the hinge main body at the time of taking the second posture, and
the second support plate has a second plate-side locking strip which protrudes toward the hinge main body side and is locked on the rear face side of the hinge main body at the time of taking the second posture.
