Abstract
There comprises a base unit having an information processing circuit and a display unit, an input unit, and a rotary axis disposed in an orthogonal direction to the base unit and the input unit for coupling therebetween. The display unit comes into an unexposed position when the input unit is turned in one direction on the rotary axis, and (ii) it comes into an exposed position when the input unit is turned in another direction on the rotary axis.
Claims19
A portable information processing device comprising:
- a base unit including a display unit;
- an input unit;
- a rotary axis disposed in an orthogonal direction to said base unit and said input unit, for coupling therebetween,
- wherein
- said display unit is in an unexposed position when said input unit is turned in one direction on said rotary axis, and
- said display unit is in a sufficiently exposed position when said input unit is turned in another direction on said rotary axis;
- and
- a detection element for detecting an exposed position of said display unit, wherein, when said input unit and said display unit are turned on said rotary axis,
- said detection element turns on a power supply for said portable information processing device upon detection that said display unit is sufficiently exposed, and
- said detection element turns off the power supply for said portable information processing device upon detection that said display unit is not exposed sufficiently.

A portable information processing device comprising:
- a display unit;
- a base unit including an information processing circuit and being operably coupled to said display unit;
- an input unit operably coupled to said base unit;
- a rotary axis disposed in an orthogonal direction to said display unit and said input unit, for coupling therebetween,
- wherein
- said display unit is in an unexposed position when said input unit is turned in one direction on said rotary axis, and
- said display unit is in a sufficiently exposed position when said input unit is turned in another direction on said rotary axis;
- and
- a detection element for detecting an exposed position of said display unit, wherein, when said input unit and said display unit are turned on said rotary axis,
- said detection element turns on a power supply for said portable information processing device upon detection that said display unit is sufficiently exposed, and
- said detection element turns off the power supply for said portable information processing device upon detection that said display unit is not exposed sufficiently.
