Abstract
A cellular phone of the present invention comprises upper housing 10 and lower housing 20 connected together for displacement relative to each other. Upper housing 10 incorporates liquid crystal unit 30 which includes light source 35 and liquid crystal panel 34 illuminated by light emitted from light source 35. Lower housing 20 incorporates an input device. Upper housing 10 comprises slit 13 which communicates with the interior and exterior of upper housing 10, and light guide means for guiding light emitted from light source 35 to slit 35. Operating unit 21 of the input device arranged on lower housing 20 is illuminated by light which is guided by the light guide means and which is emitted to the outside of upper housing 10 through slit 13.
Claims13
A cellular phone comprising a first housing which incorporates a liquid crystal unit including a light source and a liquid crystal panel illuminated by light emitted from said light source, and a second housing which incorporates an input device, where said first housing and said second housing are coupled together for displacement relative to each other,
- wherein said first housing comprises a slit communicating with the interior and exterior of said first housing, and light guide means for guiding light emitted from said light source to said slit, and
- an operating portion of said input device disposed in said second housing is illuminated by light guided by said light guide means and emitted to the outside of said first housing through said slit.
A cellular phone comprising a first housing which incorporates a liquid crystal unit including a light source and a liquid crystal panel illuminated by light emitted from said light source, and a second housing which incorporates an input device, where said first housing and said second housing are coupled together for displacement relative to each other,
- wherein said first housing comprises a slit communicating with the interior and exterior of said first housing, and light guide means for guiding light emitted from said light source to said slit, and
- an operating portion of said input device disposed in said second housing is illuminated by light guided by said light guide means and emitted to the outside of said first housing through said slit.
- wherein said liquid crystal unit comprises:
- a frame which contains said light source;
- a diffusion plate for diffusing light emitted from said light source;
- a first reflective sheet for reflecting light diffused by said diffusion plate toward said liquid crystal panel;
- and
- a second reflective sheet for reflecting the light diffused by said diffusion plate toward an opening formed on said frame,
- wherein said opening formed at a position opposite to said slit, and
- said diffusion plate, said first reflective sheet, and said second reflective sheet are contained in said frame.
