Abstract
Abstract An angular section used for condition indication has a first indication hole and a second indication hole. An indication element and a printed circuit board provided with a light-emitting diode are arranged inside the angular section. The indication element is made up of a light-transmission portion and an attachment portion. The light-transmission portion includes a first indication surface fitted in the first indication hole, a second indication surface fitted in the second indication hold, a slanted reflecting surface for reflecting incident light toward the second indication surface, and a light-incident surface extending between the lower end of the reflecting surface and the lower side of the attachment portion. Part of the light emitted from the light-emitting diode passes straight through the light-transmission portion, and emerges from the first indication surface, thus illuminating the first indication surface. The remaining light is reflected upward by the reflecting surface, and emerges from the second indication surface, thus illuminating the second indication surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
269 words
A personal computer provided with both a condition indicator and a keyboard, comprising: a top cover; an angular section including first and second walls, said first wall being upright on the top cover and having a first indication hole, and said second wall being horizontal and continuous with an upper edge of the first wall and having a second indication hole; an indication element formed of a light-transmission material of a non light-diffusion type and arranged inside of the angular section, said indication element including a light-transmission portion partly fitted in both the first and second indication holes, and an attachment portion integral with the light-transmission portion and attached to the second wall; a printed circuit board arranged inside the angular section in the vicinity of the indication element and being substantially parallel to the second wall; and a light-emitting element attached to the printed circuit board and adapted to emit light toward the first indication hole, said light-transmission portion including: a first indication surface which is fitted in the first indication hole and is located on an outer surface of the first wall in an exposed state; a second indication surface which is fitted in the second indication hole and is located on the outer surface of the second wall in an exposed state; a slanted reflecting surface located at a lower level than that of the first surface and adapted to reflect part of the light emitted from the light-emitting element toward the second indication surface; and a light-incident surface extending between a lower edge of the reflecting surface and a lower face of the attachment portion.
Claim 2
Dependent Claim
269 words
A personal computer provided with both a condition indicator and a keyboard, comprising: a top cover; an angular section including first and second walls, said first wall being upright on the top cover and having a first indication hole, and said second wall being horizontal and continuous with an upper edge of the first wall and having a second indication hole; an indication element formed of a light-transmission material of a non light-diffusion type and arranged inside of the angular section, said indication element including a light-transmission portion partly fitted in both the first and second indication holes, and an attachment portion integral with the light-transmission portion and attached to the second wall; a printed circuit board arranged inside the angular section in the vicinity of the indication element and being substantially parallel to the second wall; and a light-emitting element attached to the printed circuit board and adapted to emit light toward the first indication hole, said light-transmission portion including: a first indication surface which is fitted in the first indication hole and is located on an outer surface of the first wall in an exposed state; a second indication surface which is fitted in the second indication hole and is located on the outer surface of the second wall in an exposed state; a slanted reflecting surface located at a lower level than that of the first surface and adapted to reflect part of the light emitted from the light-emitting element toward the second indication surface; and a light-incident surface extending between a lower edge of the reflecting surface and a lower face of the attachment portion.
Claim 3
Dependent Claim
41 words
A personal computer according to claim 1, wherein said second indication hole is continuous with an upper end region of the first indication hole, and said second indication surface is continuous with an upper end portion of the first indication surface.
Claim 4
Dependent Claim
16 words
A personal computer according to claim 1, wherein said angular section is located behind the keyboard.
Claim 5
Dependent Claim
28 words
A personal computer according to one of claims 1 and 2, wherein the first wall of said angular section extends in a width direction of the top cover.
Claim 6
Dependent Claim
29 words
A personal computer according to claim 4, wherein said first wall is inclined such that an upper edge thereof is closer to a rear portion of the top cover.
Claim 7
Dependent Claim
15 words
A personal computer according to claim 1, wherein said light-emitting element is a light-emitting diode.
Claim 8
Dependent Claim
17 words
A personal computer according to claim 1, wherein said light-transmission portion includes at least two light-transmission parts.
Claim 9
Dependent Claim
44 words
A personal computer according to claim 7, wherein said angular section includes at least one lightshielding rib which is integrally projected from an inner surface of the angular section, said at least one lightshielding rib being located between adjacent ones of the light-transmission portions.
Claim 10
Dependent Claim
13 words
A personal computer according to claim 1, wherein said light-incident surface is curved.
Claim 11
Dependent Claim
62 words
A personal computer according to claim 1, wherein said top cover swingably supports a display housing which can cover the keyboard, said display housing completely exposing the angular section when the display housing is raised with reference to the top cover, and covering the first wall and exposing the second wall when the display housing is laid down to cover the keyboard.
