ABSTRACT:
A notebook type information processing apparatus includes a display and an apparatus body. The display has a screen on one side for displaying data, a support supporting the screen rotatably, a first connector provided on the bottom of the support and connectable to the apparatus body mechanically and electrically, and a latch that is rotatable 180 degrees for locking the display to the apparatus body in either a normal position or an inverted position. The apparatus body has a groove engageable with the support and located at the rear of a keyboard, a second connector positioned in the groove and connectable to the first connector mechanically and electrically, a pair of rotatable levers engageable with opposite ends of the support for locking the display, a control section for generating control signals meant for the screen, a position detecting circuit for determining whether the display is mounted in the normal or inverted positions, and a selector circuit for selectively outputting the control signals from the control section on the basis of the output of the detecting circuit. Hence, the apparatus allows the user to enter data and commands with a pen easily, reduces the fatigue of the user's arm, and allows the entering operation to be continued for a long time.
