ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a case mounting for an external suspending CD drive and more particularly to a mounting that is integrally formed with the casing of the CD drive.
2. Description of the Prior Art
Conventional externally suspended CD drives, such as the one shown in
FIG. 1
, mainly include an upper case
10
, an optical disk processing unit
20
, a circuit board
30
and a lower case
40
. The upper case
10
and the lower case
40
form an accommodation space in between to house both the optical disk processing unit
20
and the circuit board
30
. The optical disk processing unit
20
receives an optical disk
50
from a lateral side thereof through a slot on a side wall (not shown in the figure) of the CD drive, and equipped with the necessary circuits to perform read and/or write functions. The read/write function upon the optical disk
50
is a process requiring high precision. Hence, one of the main technical issues for such a CD drive is to isolate the optical disk processing unit
20
from external shock, and to diminish motor vibration as well.
In order to enhance operational accuracy of the optical disk processing unit
20
, to properly hold the optical disk processing unit
20
in the CD drive and to reduce the influence of external shock, a conventional CD drive has four shock-absorbing rubbers
102
hanging independently in the interior of the upper case
10
. Such a type of CD drive is commercially called an external suspending CD drive. On opposing lateral sides
106
of the upper case
10
, there are provided with four mounting devices
60
. Each of the mounting devices
60
has a bracket
605
bending inward from the lateral side
106
and thereby holding a shock-absorbing rubber
102
. The shock-absorbing rubber
102
has an upper end engaging with the optical disk processing unit
20
and a free lower end to keep the circuit board
20
from colliding with the optical disk processing unit
20
. The rubber
20
may absorb or reduce shock, to steadily hold the optical disk processing unit
20
. It happens that, during transportation or carrying of the CD drive, any movement, particularly lateral movement, gives rise to huge sideward motion of the optical disk processing unit
20
and may result in damage of the CD drive.
In order to solve the problem mentioned above, a new technique has been developed as shown in FIG.
2
. At a corresponding position on each inside wall of each lateral side
106
′ and close to an adjacent rear side
104
′, a stopping flange
601
is provided. Each stopping flange
601
is held at an angle, preferably ninety degrees, against the bracket k
605
;. There is further a stopper
603
to hold against the stopping flange
601
. Both the stopping flange
601
and the stopper
603
are riveted or screwed to the lateral sides
106
′ for preventing the optical disk processing unit
20
from moving rearwardly. While such a design helps to hold the CD drive steady during transportation and/or carrying, it requires more components and more assembly work, so that cost of production is increased.
SUMMARY OF THE INVENTION
In view of the aforesaid disadvantages, it is therefore an object of this invention to provide a case mounting for a CD drive that is integrally formed with the casing so that it can be produced simply, and at low cost.
It is another object of this invention to provide a mounting for a CD drive that is integrally produced with the CD casing for achieving higher quality.
The mounting according to this invention includes a stopping flange and a stopper located on an inside wall of a lateral side of the CD casing for preventing the optical disk processing unit from moving rearwardly. The mounting is integrally formed with the casing in one piece so that it may be made with fewer components at lower cost and higher quality.
The stopping flange, which is a protrusive flange extending inward from a lateral side of the CD casing, makes contact with the optical disk processing unit, so that the optical disk processing unit cannot move rearwardly to collide with the rear wall of the casing upon external forcing. In one embodiment of the present invention, the stopping flange is bent, preferably 90 degrees, from an end of a bracket formed from the lateral side.
The stopper in accordance with the present invention is a protrusive bulge formed in the lateral side, for preventing the stopping flange from deforming under external force. In a preferred embodiment, mountings are provided at two opposite lateral sides for holding the optical disk processing unit at two sides. The stopper acts as a reinforcement member.
