ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a peripheral apparatus for personal computer (PC) cards, which is used for connecting PC cards to a PC such as a laptop type PC and a note type PC.
DESCRIPTION OF THE RELATED ART
Especially, at a laptop type PC or a note type PC in personal computers, the cabinet of the note type PC is sized small, consequently, when a modulator-demodulator (MODEM) for data communication or a memory is additionally installed, installing them in the cabinet may have difficulty in size.
In order to avoid the difficulty, recently the MODEM or the additional memory is installed in the PC card. And the PC card is inserted to a slot of a PC card slot unit that is mounted on a printed circuit board (PCB) of the PC, and the PC card connects to the PC via connectors. In this, the PC card slot unit is designed to meet the peripheral component interconnect (PCI) bus system recommended by the personal computer memory card international association (PCMCIA).
FIG. 1
is a perspective view illustrating a conventional peripheral apparatus for PC cards. As shown in
FIG. 1
, at the conventional peripheral apparatus for PC cards, a PC card slot unit
11
is installed together with other components on a PCB
21
of a PC. On the side part of the PCB
21
, an area for installing the PC card slot unit
11
is reserved and the PC card slot unit
11
is fixed on the PCB
2
with screws inserting to screw holes
21
a
of the PCB
21
.
The PC card slot unit
11
installed on the PCB
21
is electrically connected to the PCB
21
with connectors
31
a
and
31
b.
As shown in
FIG. 1
, from the positioning relation between the PC card slot unit
11
and the PCB
21
, one connector
31
a,
whose slot
31
c
is made to be upward, is fixed on the PCB
21
, and the other connector
31
b
attached to the PC card slot unit
11
is made to be downward, and the PC card slot unit
11
is installed on the PCB
21
. In this, a PC card is inserted to a PC card inserting slot
11
a
of the PC card slot unit
11
.
However, as shown in
FIG. 1
, at the conventional peripheral apparatus for PC cards, the PC card slot unit
11
is installed together with other components on the PCB
21
of the PC. On the side part of the PCB
21
, an area for installing the PC card slot unit
11
is reserved and the PC card slot unit
11
is fixed on the PCB
21
with screws inserting to the screw holes
21
a
of the PCB
21
. Consequently, the connectors
31
a
and
31
b
are placed between the PC card slot unit
11
and the PCB
21
, and the space putting the connectors
31
a
and
31
b
and the PC card slot unit
11
on the PCB
21
is required.
At the laptop type PC or the note type PC, especially, the height of the cabinet is required to be low. As shown in
FIG. 1
, at the conventional PC, the height putting the connectors
31
a
and
31
b
and the PC card slot unit
11
must be obtained. This causes a problem that the height can not be made to be low.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a peripheral apparatus for PC cards that makes the influence giving to the height of a PC as small as possible.
According to a first aspect of the present invention, for achieving the object mentioned above, there is provided a peripheral apparatus for personal computer (PC) cards, which provides a PC card slot unit connecting to a printed circuit board (PCB) of a PC through connectors and is used by inserting PC cards to the PC card slot unit. And the connectors are constituted of a first connector fixed to the PCB and a second connector fixed to the PC card slot unit, and the first connector and the second connector are connected in a state that the both connectors can be de-connected in the opposite direction of inserting direction of PC cards, and the PC card slot unit is provided at the outside of a cabinet of the PC.
According to a second aspect of the present invention in the first aspect, a slot of the first connector is provided in the horizontal direction at the end side of the PCB, and the second connector is made of a card edge type PCB and the card edge type PCB is inserted to the slot of the first connector.
According to a third aspect of the present invention in the first aspect, the PC card slot unit is placed at the outside of the cabinet of the PC and connected to the PCB through the connectors in the horizontal direction.
According to a fourth aspect of the present invention in the first aspect, the maximum number of the PC cards inserting to the PC card slot unit is three at the same time.
