Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal computer, and more particularly to the addition of internal expansion disk units having different interfaces.

[0002]

2. Description of the Related Art Conventionally, internal expansion disk units are classified into a cartridge type file slot type and a single unit file bay type. There are differences in the external dimensions, interface, presence / absence of cables during mounting, and presence / absence of screws. At present, there is a personal computer that supports only one type of additional disk, but there is no personal computer that supports both types.

Further, as a publicly known example corresponding to both, Japanese Patent Application Laid-Open No. 4-333909 is known.

The personal computer disclosed in JP-A-4-333909 will be described with reference to the drawings.

FIG. 7 is a structural diagram showing a mounting state of an internal expansion unit different from an interface in a conventional personal computer in a function expansion slot.

In this conventional personal computer, the option card 1 having a different connection interface is used.
8 and the option cartridge 19 can be mounted in the same function expansion slot 20, in order to mount the option card expansion circuit unit 22 and the option cartridge expansion circuit unit 23 having the same interface condition as the connector 21 of the function expansion slot 20. These additional circuit units are used to convert the interface between the option card 18 and the option cartridge 19 and the connector 21.

[0007]

However, the conventional personal computer compatible with only one type of additional disk as described above has a problem of lacking versatility.

Further, in the known Japanese Unexamined Patent Publication No. 4-333909, when the internal expansion unit is replaced,
It is also necessary to replace expensive additional circuit units. Further, since an additional circuit unit is required, there is a problem that the entire apparatus of the personal computer becomes large accordingly.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to replace a plurality of internal expansion disk units with different interfaces without replacing the expansion circuit unit as in the conventional case.
It is to provide a versatile personal computer that can be easily replaced and mounted.

Therefore, the personal computer of the present invention is
The device is connected to a means for switching a plurality of disk units with different interfaces through a dedicated attachment method to fix the disk units in the same space in the device, and a connector for each of the plurality of disk units. A plurality of connectors and means for connecting to the device.

The personal computer of the present invention has a frame for switching between two types of disk units for expansion of different types using dedicated chassis and fixing them in the same space, and one for expansion of one. A sub board having a first connector for receiving a signal from the disk unit and a second connector for receiving a signal from the other expansion disk unit and connected to a connector of a main board mounted in the apparatus. It has

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a structural view showing an embodiment of a personal computer of the present invention, and FIG. 1 (a) is a plan view thereof.
FIG. 1B is a side view thereof.

The personal computer 1 includes a frame 3 for fixing two types of expansion disk units (file slot type, file bay type) of different types in the same space 2, and an expansion disk unit. It has a sub board 5 to be connected, and has a structure in which the sub board 5 is directly attached to the connector 6 provided on the main board 4 mounted on the personal computer 1. And
The sub-board 5 has a connector 7 for receiving a signal from a file slot type additional disk unit and a connector 8 for receiving a signal from a file bay type additional disk unit.

Next, a case where a file slot type additional disk is attached to the personal computer of the present embodiment will be described with reference to the drawings.

FIG. 2 is a plan view of a personal computer of this embodiment in which a file slot type additional disk unit is attached, FIG. 2 (a) is its plan view, and FIG. 2 (b) is FIG. 2 (a). It is a detailed view of part A of FIG.

First, a chassis (file slot type) 9 which is a file slot type attachment is inserted into the frame 3. At this time, the chassis 9 is fixed to the frame 3 by the snap fit by the convex portion 10 and the concave portion 11. Next, the file slot type additional disk unit 12 is inserted into the chassis 9, and the connector of the additional disk unit 12 and the connector 7 of the sub board 5 are connected. In this case, since the additional disk unit (file slot type) 12 is of the cartridge type, it is not necessary to screw it for connecting and fixing the cable.

The attachment of the file slot type additional disk unit will be described in detail with reference to the perspective views of FIGS. 3, 4 and 5.

FIGS. 3, 4 and 5 are perspective views for explaining the attachment of the file slot type additional disk unit to the personal computer of this embodiment.

In FIG. 3, a personal computer 1 is provided with a chassis 3, a sub board 5 having a connector 7 and a connector 8, and a connector 6 for directly mounting the sub board 5.

In FIG. 4, the space 2 of the flume 3 of FIG.
The chassis 9 is attached to the.

Then, referring to FIG. 5, the chassis 9 of FIG.
The expansion disk unit (file slot type) 12 is inserted in the inside, and the expansion disk unit 12 and the connector 7 are connected.

Next, a case where a file bay type additional disk unit is attached to the personal computer of the present embodiment will be described with reference to the drawings.

FIG. 6 is a plan view of a personal computer of this embodiment in which a file bay type additional disk unit is attached, FIG. 6 (a) is its plan view, and FIG. 6 (b) is FIG. 6 (a). It is a detailed view of part A of FIG.

First, the previously mounted additional disk unit 12 and chassis 9 are removed. Next, chassis (file bay type) which is an attachment for file bay
Insert 13 into frame 3. At this time, the chassis 13 is fixed by the snap fit between the projections 14 and the recesses 11 as in the chassis 9. Finally, a file bay type additional disk unit (file bay type) 15 is inserted. Since the file bay type is a single unit, the expansion disk unit 15 and the sub board 5 are cable 1
6 and the screws are fixed to the chassis 13.

[0026]

As described above, the personal computer of the present invention uses an expensive disk slot type / file bay type expansion disk unit such as the conventional expansion circuit unit in the switching system. There is an effect that it is possible to provide a versatile personal computer that does not need to be replaced and that can be easily replaced and mounted inexpensively.
