Abstract

This structure for mounting an indicator unit on an electronic apparatus includes an indicator unit including a wiring board and a lens member having a first pressing portion pressing a first surface of the wiring board and a housing of an electronic apparatus, mounted with the indicator unit, including a second pressing portion pressing a second surface of the wiring board. The wiring board is so held between the first pressing portion of the lens member and the second pressing portion of the housing as to be fixed.

Claims

1. A structure for mounting an indicator unit on an electronic apparatus, comprising:

an indicator unit including a wiring board mounted with a light source portion and a lens member transmitting light from said light source portion; and

a housing of an electronic apparatus mounted with said indicator unit, wherein

said lens member has a first pressing portion pressing a first surface of said wiring board toward a first direction,

said housing includes a second pressing portion pressing a second surface of said wiring board toward a second direction opposite to said first direction,

said wiring board is fixed by mounting said lens member on said housing so that said wiring board is held between said first pressing portion of said lens member and said second pressing portion of said housing while said light source portion of said wiring board is positioned with respect to said lens member,

said first pressing portion of said lens member is provided with a first boss for regulating the position of said wiring board,

said wiring board has a first boss receiving hole for receiving said first boss of said lens member, and

said light source portion of said wiring board is positioned with respect to said lens member by inserting said first boss of said lens member into said first boss receiving hole of said wiring board.

2. The structure for mounting an indicator unit on an electronic apparatus according to claim 1, wherein

said second pressing portion of said housing is constituted of a rib integrally formed on said housing.

3. The structure for mounting an indicator unit on an electronic apparatus according to claim 2, wherein

said lens member has a transmitting portion for transmitting said light from said light source portion, and

said rib constituting said second pressing portion of said housing is arranged on a position not overlapping said transmitting portion in front elevational view.

4. The structure for mounting an indicator unit on an electronic apparatus according to claim 3, wherein

a pair of said first pressing portions of said lens member are provided on right and left portions through said transmitting portion.

5. The structure for mounting an indicator unit on an electronic apparatus according to claim 4, wherein

a pair of said ribs are provided on positions corresponding to said pair of first pressing portions, and

said wiring board is so held between said pair of first pressing portions and said pair of ribs as to be fixed.

6. The structure for mounting an indicator unit on an electronic apparatus according to claim 5, wherein

said pair of ribs have horizontally symmetrical L shapes in front elevational view, and are so formed as to press two sides around the right and left corners of said wiring board respectively.

7. The structure for mounting an indicator unit on an electronic apparatus according to claim 2, wherein

said rib constituting said second pressing portion of said housing is L-shaped in front elevational view, and so arranged as to press two sides around corners of said wiring board.

8. The structure for mounting an indicator unit on an electronic apparatus according to claim 7, wherein

said first pressing portion of said lens member is so formed as to press regions corresponding to portions around said corners of said wiring board pressed by said L-shaped rib of said housing.

9. The structure for mounting an indicator unit on an electronic apparatus according to claim 4, wherein

said lens member further includes a pair of legs so integrally formed as to extend downward from both horizontal ends of said transmitting portion, and

said pair of first pressing portions are integrally formed on said pair of legs respectively.

10. The structure for mounting an indicator unit on an electronic apparatus according to claim 9, wherein

said housing further includes a pair of mounting portions for mounting said lens member, and

said lens member further includes a pair of lens-side mounting portions mounted on said pair of mounting portions of said housing and integrally formed on said pair of legs.

11. The structure for mounting an indicator unit on an electronic apparatus according to claim 10, wherein

said pair of lens-side mounting portions of said lens member are so formed as to protrude oppositely to said first direction with respect to the surfaces of said pair of legs, and

said pair of first pressing portions are formed on positions separating from said lens-side mounting portions of said legs at a prescribed interval in said first direction.

12. The structure for mounting an indicator unit on an electronic apparatus according to claim 1, wherein

said housing further includes a mounting portion for mounting said lens member,

said mounting portion of said housing has a second boss for regulating the position of said lens member, and

said lens member has a second boss receiving hole receiving said second boss of said mounting portion of said housing.

13. The structure for mounting an indicator unit on an electronic apparatus according to claim 12, wherein

said mounting portion of said housing further has a threaded hole, and

said lens member is mounted on said housing by clamping a screw member to said threaded hole of said housing while inserting said second boss of said mounting portion of said housing into said second boss receiving hole of said lens member.

14. The structure for mounting an indicator unit on an electronic apparatus according to claim 1, wherein

said electronic apparatus is a television set integrally including a disk unit, and

said indicator unit is mounted on said housing of said television set, and employed as an indicator of said disk unit.

15. A television set comprising:

a display portion displaying images;

an indicator unit including a wiring board mounted with a light source portion and a lens member transmitting light from said light source portion; and

a housing mounted with said indicator unit, wherein

said lens member has a first pressing portion pressing a first surface of said wiring board toward a first direction,

said housing includes a second pressing portion pressing a second surface of said wiring board toward a second direction opposite to said first direction,

said wiring board is fixed by mounting said lens member on said housing so that said wiring board is held between said first pressing portion of said lens member and said second pressing portion of said housing while said light source portion of said wiring board is positioned with respect to said lens member,

said second pressing portion of said housing is constituted of a rib integrally formed on said housing, and

said rib constituting said second pressing portion of said housing is L-shaped in front elevation view, and so arranged as to press two sides around corners of said wiring board.

16. The television set according to claim 15, wherein

said lens member has a transmitting portion for transmitting said light from said light source portion, and

said rib constituting said second pressing portion of said housing is arranged on a position not overlapping said transmitting portion in front elevational view.

17. The television set according to claim 15, wherein

said first pressing portion of said lens member is so formed as to press regions corresponding to portions around said corners of said wiring board pressed by said L-shaped rib of said housing.
