Portable information processor, housing of portable information processor, and method for manufacturing the housing
View Patent ↗The rear housing composing the display portion includes a raised portion and a non-raised portion with a level difference therebetween. The rear housing of the display portion is formed in such a manner that the non-raised portion has a cylindrically curved surface and that the level difference has an edge line at right angles with the lateral line of the cylindrically curved surface. The rear housing has such an automobile hood structure with a partially raised surface, thereby being prevented from being deformed due to external pressure not only in its width direction but also in its longitudinal direction.
1. A housing of a portable information processor comprising a display portion and a main body, the display portion comprising:
a rear housing including a raised portion and a non-raised portion separated by an edge line, the edge line extending in a first direction, at least one of the raised portion and the non-raised portion having an arcuate surface extending in the first direction from a first edge to a second edge opposite the first edge.
2. The housing of the portable information processor of claim 1 , wherein
the arcuate surface of the at least one of the raised portion and the non-raised portion is curved inwardly into the rear housing.
3. A housing of a portable information processor comprising a display portion and a main body, the display portion comprising:
a rear housing including a flat portion and a curved portion separated by an edge line, the edge line having an elliptical shape, a center of the curved portion concentric with a center of the rear housing.
4. The housing of the portable information processor of claim 3 , wherein
the curved portion of the rear housing is bowed inward into the rear housing.
5. A method for manufacturing a housing comprising:
fixing a planar metallic material; and
shaping a rear housing including a raised portion and a non-raised portion by pressing the planar metallic material so as to create an edge line separating the raised portion and the non-raised portion, the edge line extending in a first direction, wherein
at least one of the raised portion and the non-raised portion has an arcuate surface extending in the first direction from a first edge to a second edge opposite the first edge.
6. The method for manufacturing a housing of claim 5 , wherein
the arcuate surface of the at least one of the raised portion and the non-raised portion is curved inwardly into the rear housing.
7. The method for manufacturing a housing of claim 5 , wherein
the planar metallic material is a magnesium alloy.
8. A portable information processor comprising:
a display portion including a liquid crystal display device having a liquid crystal display panel;
a main body attached to be rotatable with the display portion, the main body including an information processing unit connected to the display portion; and
an outer housing including a rear housing that comprises a surface of the display portion, the surface being opposite to an other surface of the display portion on which the liquid crystal display panel is disposed, wherein
the rear housing includes a raised portion and a non-raised portion separated by an edge line, the edge line extending in a first direction, and at least one of the raised portion and the non-raised portion having an arcuate surface extending in the first direction from a first edge to a second edge opposite the first edge.
9. A portable information processor comprising:
a display portion including a liquid crystal display device having a liquid crystal display panel;
a main body attached to be rotatable with the display portion, the main body including an information processing unit connected to the display portion; and
an outer housing including a rear housing that comprises a surface of the display portion, wherein
the surface is opposite to an other surface of the display portion on which the liquid crystal display panel is disposed, and the rear housing includes a flat portion and a curved portion separated by an edge line, with the edge line having an elliptical shape, a center of the curved portion concentric with a center of the rear housing.
