ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to a computer, and more particularly, to a computer for coupling auxiliary memory units to a fixing bracket.
2. Description of the Related Art
Generally, a computer is classified as a tower type (e.g., a stand type) or a desktop type, according to a shape of a casing of the computer.
Casings of both the tower type and desktop type computers, include a front panel forming a front part of the casing, a rear panel forming a rear part of the casing and having slots for a plurality of connectors, and a cover forming a housing space together with the front and rear panels. For the desktop type computer casing, the width of the casing is greater than the height thereof. In the tower type computer casing, the height is greater than the width. Hereinafter, the tower type computer casing will be described.
As shown in
FIG. 1
, a computer system includes a main body
101
having a casing
110
, a plurality of hardware components such as an auxiliary memory unit
121
accommodated in the casing
110
, and a monitor (not shown) displaying a picture thereon, on the basis of a picture signal received from the main body
101
.
The casing
110
includes a front panel
120
having openings
125
through which the auxiliary memory unit
121
(e.g., a CD-ROM drive, a floppy disk drive, etc.) is received. The casing
110
also includes a rear panel
140
having a plurality of slots
141
through which peripheral units such as the monitor are connected, a supporting panel
130
combining the front panel
120
with the rear panel
140
and forming a floor for the casing, and side walls between the front and rear panels
120
and
140
. A cover
150
of the casing
110
forms a housing space together with the front, rear and supporting panels
120
,
140
and
130
.
A front of the front panel
120
has a power switch (not shown), a reset switch (not shown), and on a rear thereof, a fixing bracket
160
supporting the auxiliary memory unit
121
.
The fixing bracket
160
is made of steel and, as shown in
FIGS. 1 and 2
, has a box shape. A front end of the fixing bracket
160
is positioned on the front panel
120
, and a rear end thereof, is positioned over a middle of the supporting panel
130
. Further, side walls of the fixing bracket
160
are formed with a plurality of through holes
162
corresponding to screw holes
123
formed on the auxiliary memory unit
121
so that the auxiliary memory unit
121
is fastened on the fixing bracket
160
with bolts
127
. Thus, the fixing bracket
160
selectively accommodates the auxiliary memory unit
121
.
However, in the conventional computer casing, a screwdriver is needed to fasten and remove auxiliary memory units against a fixing bracket. Consequently, bolts used to fasten the auxiliary memory units on the fixing bracket are lost because the bolts are comparatively small.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a computer in which an auxiliary memory unit is removably fastened on a fixing bracket without a screwdriver.
Additional objects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
The foregoing and other objects of the present invention are achieved by providing a computer including a casing mounted with an auxiliary memory unit having at least one fixing hole, a fixing bracket accommodating and supporting the auxiliary memory unit in the casing, and having a through hole corresponding to the fixing hole of the auxiliary memory unit, and a fixing member having a fixing projection inserted into the through hole of the fixing bracket and the fixing hole of the auxiliary memory unit so as to fasten the auxiliary memory unit on the fixing bracket.
According to an aspect of the invention, the computer includes a guiding groove on a surface of the fixing bracket and guiding the fixing member.
According to another aspect of the invention, the computer includes a fastening device removably fastening the fixing member on the fixing bracket.
According to another aspect of the invention, the fastening device has a pivot supporting part supporting a first end of the fixing member on the casing and a rotation part fastened on the fixing bracket by pivoting a second end of the fixing member on the pivot supporting part. The pivot supporting part has a holding part on the casing and a latch part that is on the fixing member and latched on the holding part. The rotation part has a hook holder on the fixing bracket and a hook on the fixing member to be locked in and released from the hook holder.
According to another aspect of the invention, the fixing member has a first part having the fixing projection and the latch part, and a second part removably coupled to the first part and having the hook. The first and second parts include a hook hole and a hook projection, respectively, which are removably coupled to each other along a lengthwise direction.
According to an aspect of the invention, the first part is made of metal and the second part is made of a plastic material having elasticity.
According to another aspect of the invention, the second part includes a handle.
