Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an MD (mini-disc) player, a CD (compact disc) player,
The present invention relates to a relatively small electronic device such as a tape recorder, a video camera, and a radio.

[0002]

2. Description of the Related Art Conventionally, for example, a small electronic device as shown in FIG. 15 has been known.
The electronic device shown in FIG. 15 is an MD player that reproduces information such as music using an MD (mini-disc) as an information recording medium. This MD player 1
Top panel assembly 2 and bottom panel assembly 3 appearing in the figure
And a chassis assembly and a mechanical deck assembly that do not appear in the drawing.

[0003] The chassis assembly is formed of a square frame formed of sheet metal, and a mechanical deck assembly is housed in the chassis assembly. The mechanical deck assembly includes a mechanical chassis to which a spindle motor is attached, a cartridge holder for holding an inserted optical disk and mounting the optical disk on the spindle motor. A bottom panel assembly 3 is arranged so as to cover the bottom surface of the mechanical deck assembly, and is fixed to the chassis assembly with fixing screws. The upper panel assembly 2 arranged to cover the upper surface of the mechanical deck assembly is supported by the chassis assembly via a flip-up mechanism so as to be openable and closable. The cartridge slot is opened and M
D can be inserted.

A decorative band assembly 4 such as a decorative band is wound around the side surface of the chassis assembly so as to be in close contact with each other. This decorative band assembly 4 is formed of a square frame like the chassis assembly, and its sectional shape is shown in FIG.
An L-shape as shown in FIG. 16A and a U-shape as shown in FIG. 16B are known. As shown in FIGS. 15 and 16A and 16B, these decorative band assemblies 4
The four sides are respectively fastened to members on the chassis side with fixing screws 5 to assemble the chassis assembly 6.
And is configured integrally.

[0005]

However, in the conventional electronic device as described above, the decorative band assembly 4 is attached to the chassis assembly 6 with a plurality of fixing screws 5, and the head of the fixing screw 5 Is not only inferior in appearance, but also because the use of a plurality of fixing screws 5 increases the number of parts, and requires screw processing and screw tightening man-hours, resulting in cost reduction. There was a problem of getting up.

To solve such a problem, as shown in FIG. 16C, a method of concealing the fixing screw 5 mounting portion of the decorative band assembly 4 by the bottom panel assembly 3 is considered. However, the method of concealing the fixing screw 5 by the bottom panel assembly 3 cannot solve the problems such as an increase in the number of parts and the screwing position is offset to one side in the width direction. There is a problem that 4 cannot be fixed in a well-balanced manner. In addition, since the widthwise dimensions of the decorative band assembly 4 and the chassis assembly 6 become longer, there is also a problem that the thickness of the entire electronic device increases.

Therefore, a method of attaching the decorative band assembly 4 to the chassis assembly 6 without using the fixing screw 5 will be considered. As such an attachment method, for example, a method shown in FIG. 17A can be considered. The decorative band assembly 7 used in this mounting method has L-shaped hooking pieces 7a formed at a plurality of locations on the upper edge thereof, and the hooking pieces 7a are hooked on the chassis assembly 6. After such temporary fixing, the bottom panel assembly 3
Is screwed to the chassis assembly 6, so that the decorative band assembly 7 can be pressed against the chassis assembly 6 and fixed integrally therewith.

In the decorative band assembly 7 having such an L-shaped cross section, since the decorative band assembly 7 itself has a simple shape, as shown in FIG. Can be made extremely simple. That is, the dies can be composed of only two dies 8 and 9 after injection molding.
Are moved in the direction X away from each other, the molded decorative band assembly 7 can be easily taken out.

However, as shown in FIG. 17C, when the decorative band assembly 7 has a U-shaped cross section, the mold structure becomes extremely complicated. That is, the mold is also composed of the male mold 10 and the female mold 11,
The male mold 10 requires a mechanism for individually sliding the two convex portions 10a and 10b that enter the inside of the U-shape. According to the molds 10 and 11, after the injection molding, first, the first protrusion 10a is moved to the second position as shown by the arrow X1.
Move to the side of the convex portion 10b. Next, the second convex portion 10b
Is moved in the direction indicated by the arrow X2, and is taken out from the U-shaped portion of the decorative band assembly 7. Thereafter, by moving the two dies 10, 11 in the direction X3 away from each other, the molded decorative band assembly 7 can be taken out.

Therefore, when the decorative band assembly having such a U-shaped cross section is used, the molds 10 and 11 become extremely complicated, so that the cost for manufacturing the molds increases. In addition, there is a problem in that the mass productivity in manufacturing the decorative band assembly is lowered, and the cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and a decorative band assembly having a U-shaped cross section can be manufactured with a mold having a relatively simple structure.
It is an object of the present invention to provide an electronic device capable of attaching a decoration band assembly to a chassis assembly without using screws.
