Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
313 words
A notebook type information processing apparatus having an input function with a pen, comprising: an apparatus body; and a display, wherein said display includes a first connector through which control signals are transmitted, wherein said apparatus body includes: a groove formed on said apparatus body for selectively locking and unlocking said display to and from said apparatus body; and connector means, connectable to said first connector and through which said control signals are transmitted from and to said apparatus body in a configurationally and electrically symmetrical condition, for connecting said display to said apparatus body, and wherein said connector means comprises: determining means for determining which of two orientation states said display is connected to said apparatus body, wherein said display is selectively connected to said apparatus body in a first and a second orientation state, and said display is changed back and forth between said first and said second orientation states by disconnecting said display from said apparatus body, turning said display by 180° around a center line of said display, said center line being substantially perpendicular to a connecting line between said display and said apparatus body, and reconnecting said display to said apparatus body; a second connector connectable to said first connector through which said control signals are transmitted from and to said first connector; and an arranging circuit for arranging spatial orders of said control signals on the basis of said orientation states, said arranging circuit maintaining said spatial orders of said control signals from and to said second connector when said determining means determines said display is at one of said two orientation states, and said arranging circuit arranging said spatial orders of said control signals in the reverse order and supplying said arranged control signals from and to said second connector when said determining means determines said display is at the other of said two orientation states.
Claim 2
Dependent Claim
313 words
A notebook type information processing apparatus having an input function with a pen, comprising: an apparatus body; and a display, wherein said display includes a first connector through which control signals are transmitted, wherein said apparatus body includes: a groove formed on said apparatus body for selectively locking and unlocking said display to and from said apparatus body; and connector means, connectable to said first connector and through which said control signals are transmitted from and to said apparatus body in a configurationally and electrically symmetrical condition, for connecting said display to said apparatus body, and wherein said connector means comprises: determining means for determining which of two orientation states said display is connected to said apparatus body, wherein said display is selectively connected to said apparatus body in a first and a second orientation state, and said display is changed back and forth between said first and said second orientation states by disconnecting said display from said apparatus body, turning said display by 180° around a center line of said display, said center line being substantially perpendicular to a connecting line between said display and said apparatus body, and reconnecting said display to said apparatus body; a second connector connectable to said first connector through which said control signals are transmitted from and to said first connector; and an arranging circuit for arranging spatial orders of said control signals on the basis of said orientation states, said arranging circuit maintaining said spatial orders of said control signals from and to said second connector when said determining means determines said display is at one of said two orientation states, and said arranging circuit arranging said spatial orders of said control signals in the reverse order and supplying said arranged control signals from and to said second connector when said determining means determines said display is at the other of said two orientation states.
Claim 3
Dependent Claim
35 words
The apparatus as claimed in claim 1, wherein said display comprises a latch rotatable 180 degrees for locking said display to said apparatus body when said display is closed while selectively facing inside or outside.
Claim 4
Dependent Claim
43 words
A notebook type information processing apparatus as recited in claim 1, wherein said determining means comprises a pull-up resistor, and wherein a signal line connects said display and said apparatus body, said determining means being responsive to a level of said signal line.
Claim 5
Dependent Claim
65 words
A notebook type information processing apparatus as recited in claim 1, wherein said processing apparatus includes a support on which said display is rotatably supported, said first connector protruding from said support, and wherein said connector means is provided in said groove in said apparatus body, said first connector being mechanically and electrically connected with said second connector of said connector means in said groove.
