Electronic device having detachable keyboard clamped by a rotatable display when closed over the keyboard

摘要

A personal computer includes a main body having a stepped portion formed in a front portion of an upper surface of the main body. The stepped portion has a bottom surface lower in level than the upper surface. A keyboard is detachably placed in the stepped portion so that when a display rotatably mounted on the main body is rotated to its closed position, it is clamped between the display and the bottom surface of the stepped portion. A protruding portion protrudes from the bottom surface of the stepped portion and extends through a through hole formed in the keyboard so to restrain the movement of the keyboard when the keyboard is mounted in the stepped portion. The protruding portion has an abutment portion which is brought into contact with the display rotated to the closed position and supports the display. When the display is rotated to the closed position, a hook on the display engages an engagement portion formed in the protruding portion.
