Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 is a front view of a television receiver, FIG. 2 is an enlarged front view of a control button portion, and FIG. 3 is a cross-sectional view of the control button portion.
The television receiver 12 includes a CRT type television main body 14 including a screen display section 1402, a control circuit section for projecting an image and the like on the screen display section 1402, and a housing 16 accommodating the television main body 14. It has.
The housing 16 is configured to include a frame-shaped front panel 20 extending vertically and horizontally on the screen display unit 1402.
At the lower side of the front panel 20, various control buttons 22 for channel switching, volume adjustment, and the like are provided.
The housing 16 and the control button 22 are both made of synthetic resin, and the housing 16 and the control button 22 are integrally formed using a mold.
[0007]
As shown in FIG. 3, the control button 22 includes a base 2202 connected to the front panel 20, and an operation unit 2204 that rises from the base 2202 and is elastically deformed when pressed by a user. The periphery is separated from the front panel 20 via a space 2205.
In the present embodiment, a pressing portion 2204A is formed to protrude on the surface of the operation portion 2204, and a convex portion 2206 projects in a cylindrical shape on the back surface of the operation portion 2204. When the user presses the pressing portion 2204A, the base portion 2202 The operation unit 2204 falls inside the housing 16 with the fulcrum as a fulcrum, and the protrusion 2206 is configured to open and close the tact switch 2402 on the printed circuit board 24 disposed behind the control button 22.
Further, in the present embodiment, a decorative nameplate 26 made of synthetic resin is attached to the lower side of front panel 20 such that pressing portion 2204A of each operation portion 2204 is exposed from window 2602.
[0008]
Next, a service button unit used for repairing the control button 22 will be described.
FIG. 4 shows a perspective view of the service button unit.
The service button unit 30 is made of a synthetic resin and is integrally formed by a mold. The first fixing portion 3002 fixed to the first flat surface 1610 (see FIG. 3) inside the housing 16, A second fixing portion 3004 fixed inside to a second flat surface 1612 (see FIG. 3) intersecting with the first flat surface 1610, and all of the second fixing portions 3004 project from the second fixing portion 3004 so as to be spaced apart from each other. And a plurality of service buttons 3006 corresponding to the operation unit 2204 of the control button 22.
On the front surface of each service button 3006, a pressing portion 3008 having substantially the same shape as the pressing portion 2204A is provided. On the back surface of the service button 3006, a convex portion 3010 having substantially the same shape as the convex portion 2206 is provided. Are formed so as to have substantially the same shape as the operation unit 2204 of the plurality of control buttons 22.
Each of the service buttons 3006 is configured so that the first and second fixing portions 3002 and 3004 are fixed to the flat surfaces 1610 and 1612 so as to be located at substantially the same position as the operation portions 2204 of all the control buttons 22. I have.
[0009]
Next, a case where the control button 22 is damaged and repaired will be described.
FIG. 5 is a cross-sectional view showing a state in which one control button 22 is broken, FIG. 6 is a front view showing a state in which one control button 22 is broken, and shows a state in which the cosmetic nameplate 26 is removed, and FIG. FIG. 4 shows a cross-sectional view of the attached state.
As shown in FIGS. 5 and 6, one control button 22 is damaged due to long-term use of the user or hit by something, and only the base portion 2202 remains.
In the present embodiment, first, all control buttons 22 remaining without being damaged are removed.
Next, as shown in FIG. 7, the first fixing portion 3002 is fixed to the first flat surface 1610 inside the housing 16 using an adhesive or a double-sided tape, and the second fixing portion 3002 is fixed. The service button 3006 is fixed to the second flat surface 1612, and the plurality of service buttons 3006 are located at substantially the same positions as the operation parts 2204 of all the control buttons 22 which are not damaged.
When the service button unit 30 is disposed in this manner and the user presses the service button 3006, the convex portion 3010 opens and closes the switch 2402 in the same manner as the conventional control button 22. Is adjusted.
[0010]
According to the present embodiment, when the control button 22 is damaged, it is not necessary to replace the entire housing 16 as in the related art, and the service button unit 30 can be used to repair only the control button 22 and repair. This is extremely advantageous in greatly reducing the cost of parts at the time.
Further, even when the housing 16 is manufactured overseas, since only the control button 22 can be repaired as described above, problems such as procurement and transportation costs can be solved.
In many cases, the control button 22 is located below the front of the CRT, and when the control button 22 is damaged, the heavy CRT is replaced from the open space on the bottom of the front of the housing 16. The service button unit 30 can be provided and fixed without performing. Therefore, the work by the worker can be simplified, which is extremely advantageous in reducing labor costs.
Further, in the present embodiment, the synthetic name plate 26 made of synthetic resin is adhered to the lower side of the front panel 20 so that the pressing portion 2204A of each operation portion 2204 is exposed from the window 2602, and thus remains. The base 2202 of the control button 22 cannot be visually recognized from the outside, and therefore has excellent appearance despite being repaired with the service button unit 30.
[0011]
Note that, in the above-described embodiment, a case has been described in which two fixed portions, that is, the first fixed portion 3002 and the second fixed portion 3004 are provided, but one fixed portion may be provided.
In addition, in addition to bonding using an adhesive or a double-sided tape, a structure in which the fixing portion is fixed to the housing is fastened with screws or a boss is provided in the housing in advance, and the boss is fixed to the housing. Various methods are applied, such as fixing by fitting into the hole of the part.
Further, in the above-described embodiment, a television receiver provided with a plurality of control buttons has been described. However, the present invention is of course applicable to a case where a single control button is provided.
In this case, the housing has a fixed portion fixed to the inside of the housing, and a service button protruding from the fixed portion and having substantially the same shape as the operation portion of the control button and capable of being elastically deformed. A service button member is prepared in which the service button is fixed to the inside so that the service button is located at substantially the same position as the operation unit. Then, when the control button is broken, the service button may be disposed at the original position where the operation unit is located by fixing the fixing unit inside the housing.
