Abstract
Abstract An angular section (19) used or condition indication has a first indication hole (20) and a second indication hole (21). A indication element (31) and a printed circuit board (32) provided with a light-emitting diode (33) are arranged inside the angular section (19). The indication element (31) is made up of a light-transmission portion (37) and an attachment portion (36). The light-transmission portion (37) includes a first indication surface (38) fitted in the first indication hole (20), a second indication surface (39) fitted in the second indication hole (21), a slanted reflecting surface (40) for reflecting incident light toward the second indication surface (39), and an arcuate light-incident surface (41) extending between the lower end of the reflecting surface (40) and the lower side of the attachment portion (36).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
329 words
A personal computer provided with both a condition indicator and a keyboard, comprising: a top cover (13); an angular section (19) including first and second walls (17, 18), said first wall (17) being upright on the top cover (13) and having a first indication hole (20), and said second wall (18) being horizontal and continuous with an upper edge of the first wall (17) and having a second indication hole (21); an indication element (31) formed of a light-transmission material and arranged inside of the angular section (19), said indication element (31) including a light-transmission portion (37) which has: a first indication surface (38) fitted in the first indication hole (20) and located on an outer surface of the first wall (17) in an exposed state; a second indication surface (39) fitted in the second indication hole (21) and located on an outer surface of the second wall (18) in an exposed state; and a light-incident surface (41), said indication element (31) further including an attachment portion (36) integral with the light-transmission portion (37) and attached to the second wall (18); a printed circuit board (32) arranged inside the angular section (19) in the vicinity of the indication element (31); and a light-emitting element (33) attached to the printed circuit board (32) and adapted to emit light toward the first indication hole (20), characterized in that: said printed circuit board (32) is arranged substantially parallel to the second wall (18); said indication element (31) is formed of a light-transmission material of a non light-diffusion type; and said light light-transmission portion (37) includes a reflecting surface (40) which reflects part of the light emitted from the light-emitting element (33) toward the second indication surface (39), said reflecting surface (40) being slanted and located at a lower level than that of the first indication surface (38), and said light-incident surface (41) being extending between a lower end of the reflecting surface (40) and a lower side of the attachment portion (36).
Claim 2
Dependent Claim
329 words
A personal computer provided with both a condition indicator and a keyboard, comprising: a top cover (13); an angular section (19) including first and second walls (17, 18), said first wall (17) being upright on the top cover (13) and having a first indication hole (20), and said second wall (18) being horizontal and continuous with an upper edge of the first wall (17) and having a second indication hole (21); an indication element (31) formed of a light-transmission material and arranged inside of the angular section (19), said indication element (31) including a light-transmission portion (37) which has: a first indication surface (38) fitted in the first indication hole (20) and located on an outer surface of the first wall (17) in an exposed state; a second indication surface (39) fitted in the second indication hole (21) and located on an outer surface of the second wall (18) in an exposed state; and a light-incident surface (41), said indication element (31) further including an attachment portion (36) integral with the light-transmission portion (37) and attached to the second wall (18); a printed circuit board (32) arranged inside the angular section (19) in the vicinity of the indication element (31); and a light-emitting element (33) attached to the printed circuit board (32) and adapted to emit light toward the first indication hole (20), characterized in that: said printed circuit board (32) is arranged substantially parallel to the second wall (18); said indication element (31) is formed of a light-transmission material of a non light-diffusion type; and said light light-transmission portion (37) includes a reflecting surface (40) which reflects part of the light emitted from the light-emitting element (33) toward the second indication surface (39), said reflecting surface (40) being slanted and located at a lower level than that of the first indication surface (38), and said light-incident surface (41) being extending between a lower end of the reflecting surface (40) and a lower side of the attachment portion (36).
