일반적으로, 노트북 PC 등의 휴대용 컴퓨터는 휴대가 간편하도록 하기 위해 부피를 최소화하여 만들어진다.Generally, a portable computer such as a notebook PC is made by minimizing the volume to make it portable.

따라서, 사운드 카드등의 각종 주변기기를 내장하지 못하고 외부의 입·출력 단자를 통해 접속시켜 사용하여야 하며 입·출력 단자 또한 일반에 비해 접속할 수 있는 주변기기 및 마우스 프린터등의 입·출력 장치의 수가 한정되므로 도킹(Docking) 또는 리플리케이터(Replicator)를 사용하여 각종 주변기기 및 입·출력 장치를 접속시킨다.Therefore, it is necessary to connect through external input / output terminals without installing various peripherals such as a sound card. Also, the number of input / output devices such as peripheral devices and mouse printers that can be connected to the input / Docking or a replicator is used to connect various peripheral devices and input / output devices.

이때, 도킹은 사운드카드, 수신카드등 다수의 주변기기를 내장한 장치이고, 리플리케이터는 키보드, 프린터등의 다수의 입·출력 장치를 통합하여 휴대용 컴퓨터에 접속시키기 위한 장치이다.At this time, the docking is a device including a plurality of peripheral devices such as a sound card and a receiving card, and the replicator is a device for connecting a plurality of input / output devices such as a keyboard and a printer to a portable computer.

그리고, 휴대용 컴퓨터의 전원이 온 된 상태에서 휴대용 컴퓨터에 도킹을 연결시킬때 각종 신호 및 데이타라인을 비롯하여 전원라인도 연결되는데, 도킹은 다수의 주변기기를 내장하고 있기 때문에 상기 다수의 주변기기가 휴대용 컴퓨터에 갑자기 연결되므로 홀트가 발생한다.When docking the portable computer in a state that the portable computer is powered on, various signals and data lines as well as power lines are connected. Since the docking includes a plurality of peripheral devices, the peripheral devices are connected to the portable computer Holt occurs because it is suddenly connected.

이때, 홀트는 휴대용 컴퓨터의 시스템이 동작을 멈추는 현상을 말한다.At this time, Holt refers to a phenomenon in which a portable computer system stops operating.

따라서, 휴대용 컴퓨터와 도킹을 연결시킬 때는 휴대용 컴퓨터의 전원을 오프 시킨 후 연결하였다.Therefore, when connecting the portable computer with the docking, the portable computer is turned off and connected.

종래의 기술에 따른 휴대용 컴퓨터는 첫째, 전원이 온 된 상태에서 도킹 또는 리플리케이터등을 연결시킬 때 갑작스런 과부하 인가로 홀트가 발생하고 이에 따라 내부 회로가 크게 손상되는 문제점이 있다.The portable computer according to the related art has a problem in that when the docking or the replicator is connected in a state where the power is on, sudden overloading occurs and the internal circuit is greatly damaged.

둘째, 도킹 또는 리플리케이터를 사용하고자 할 때 홀트를 방지하기 위해서는 먼저, 휴대용 컴퓨터의 사용을 중단하고 전원을 오프 시킨후 접속시키고 사용해야 하므로 사용자에게 불편함을 주는 문제점이 있다.Secondly, in order to prevent a halt when using a docking or a replicator, there is a problem that it is inconvenient to the user because the use of the portable computer has to be stopped and the power must be turned off and connected.

따라서, 본 발명은 상기한 종래의 제반 문제점을 해결하기 위하여 안출한 것으로서, 휴대용 컴퓨터의 전원이 온 된 상태에서 도킹 또는 리플리케이터를 연결할때 발생하는 홀트상태를 방지할 수 있도록 한 휴대용 컴퓨터를 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a portable computer capable of preventing a holt state occurring when a docking or a replicator is connected while a portable computer is powered on, There is a purpose.

The portable computer includes a connection detecting unit for detecting whether the peripheral device is connected to the portable computer and generating a signal according to the connection, And an antilocking prevention unit for preventing a Holt state, which is generated due to the connection of the operating power source, through a switching and delaying operation according to a signal of the connection detecting unit.

이하, 본 발명에 따른 휴대용 컴퓨터의 일 실시예를 첨부한 도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of a portable computer according to the present invention will be described with reference to the accompanying drawings.

도1은 본 발명에 따른 휴대용 컴퓨터의 홀트 방지장치를 나타낸 블록도이고, 도2는 도1의 홀트 방지장치의 내부 구성을 상세하게 나타낸 회로도이다.FIG. 1 is a block diagram showing an anti-halting device of a portable computer according to the present invention, and FIG. 2 is a circuit diagram showing an internal configuration of the anti-halting device of FIG. 1 in detail.

도1에 나타낸 바와 같이, 휴대용 컴퓨터의 전원라인과 도킹의 전원라인 사이에는 입·출력단자(11)를 통한 도킹과 휴대용 컴퓨터의 접속여부를 감지하고 그에 따른 신호(도킹-REQ신호)를 발생시키는 접속 감지부(12)와, 상기 도킹의 동작전원과 휴대용 컴퓨터의 동작전원의 연결로 인해 발생되는 홀트상태를 상기 도킹-REQ 신호에 따라 스위칭 및 지연동작을 통해 방지하는 홀트 방지부(10)로 이루어진 홀트 방지장치가 연결 구성된다.As shown in FIG. 1, between the power line of the portable computer and the power line of the docking, a docking through the input / output terminal 11 is detected and a signal (docking-REQ signal) A docking prevention unit 10 for preventing a docking state generated due to the connection between the operation power of the docking and the operation power of the portable computer through a switching and delaying operation according to the docking- And the resulting antihalation device is connected.

여기서, 접속 감지부(12)는 풀-업 저항(R5)과 입·출력 단자를 통해 연결되는 접지단으로 구성되고 홀트 방지부(10)는 휴대용 컴퓨터와 도킹의 상호 동작전원의 연결을 스위칭하는 스위칭부(21)와, 상기 접속 감지부(12)의 도킹-REQ신호에 따라 상기 스위칭부(21)의 스위칭을 일정시간 지연시키는 지연부(20)로 구성된다.Here, the connection detecting unit 12 is constituted by a pull-up resistor R5 and a ground terminal connected to the input / output terminal, and the antilocking unit 10 switches the connection between the portable computer and the mutual operation power of the docking And a delay unit 20 for delaying the switching of the switching unit 21 according to the docking-REQ signal of the connection sensing unit 12 for a predetermined time.

이때, 상기 스위칭부(21)는 제3트랜지스터(TR3)와 저항(R4)으로 구성된다.At this time, the switching unit 21 includes a third transistor TR3 and a resistor R4.

그리고, 상기 지연부(20)는 제1트랜지스터(TR1)와 제2트랜지스터(TR2)가 달링톤(Darlington)접속되고 저항(R1)(R2)(R3) 및 커패시터(C1)가 연결되어 구성된다.The delay unit 20 includes Darlington-connected first transistor TR1 and second transistor TR2 and resistors R1, R2, and R3 and a capacitor C1. .

이때, 상기 홀트방지의 동작전원으로 휴대용 컴퓨터의 전원을 사용한다. 상기와 같이 구성된 홀트 방지장치의 동작을 도2를 참조하여 설명하면 다음과 같다.At this time, the power of the portable computer is used as the operation power for the anti-holing. The operation of the above-configured anti-lock device will be described with reference to FIG.

노트북의 전원이 온 된 상태에서 휴대용 컴퓨터의 입·출력 단자(11)에 도킹이 접속되어 있지 않으면 접속 감지부(12)의 풀-업 저항(R5)과 접지단은 개방된 상태이므로 동작 전원이 풀-업 저항(R5)를 통해 도킹-REQ신호 라인에 인가되어 지연부(20)의 제1트랜지스터(TR1)가 온 동작하게 된다.When the docking is not connected to the input / output terminal 11 of the portable computer while the notebook is powered on, the pull-up resistor R5 and the ground terminal of the connection detecting unit 12 are in an open state, Is applied to the docking-REQ signal line through the pull-up resistor R5 so that the first transistor TR1 of the delay unit 20 is turned on.

이때, 지연부(20)의 제2트랜지스터(TR2)는 상기 제1트랜지스터(TR1)와 동일한 동작상태를 유지하므로 제2트랜지스터(TR2) 역시 온 동작하게 된다.At this time, the second transistor TR2 of the delay unit 20 maintains the same operation state as that of the first transistor TR1, so that the second transistor TR2 is also turned on.

이어서, 커패시터(C1)는 상기 제2트랜지스터(TR2)의 온 동작에 따라 충전 동작을 개시한다.Then, the capacitor C1 starts the charging operation in accordance with the ON operation of the second transistor TR2.

따라서, 'A'점의 전압레벨은 '하이' 이고 스위칭부(21)의 제3트랜지스터 (TR3)는 오프 상태를 유지하게 된다.Accordingly, the voltage level of the 'A' point is 'high' and the third transistor TR3 of the switching unit 21 is kept off.

이때, 사용자가 휴대용 컴퓨터를 사용하는 도중에 입·출력 단자(11)에 도킹을 접속하면 접속 감지부(12)의 풀-업 저항(R5)과 접지단이 연결되므로 동작전원이 접지단으로 인가되어 지연부(20)의 제1트랜지스터(TR1) 및 제2트랜지스터(TR2)는 오프 되므로 커패시터(C1)는 저항(R4)을 통해 충전된 전위를 방전한다.At this time, if the docking is connected to the input / output terminal 11 while the user is using the portable computer, the pull-up resistor R5 of the connection detecting unit 12 is connected to the ground terminal, so that the operating power is applied to the ground terminal The first transistor TR1 and the second transistor TR2 of the delay unit 20 are turned off so that the capacitor C1 discharges the potential charged through the resistor R4.

이때, 상기 방전은 저항(R4)과 커패시터(C1)의 시정수에 따라 일정시간 동안 이루어진다.At this time, the discharge is performed for a predetermined time according to the time constant of the resistor R4 and the capacitor C1.

그리고, 'A'점의 전압레벨은 상기 일정시간에 걸쳐 하이에서 로우로 변화하고 스위칭부(21)의 제3트랜지스터(TR3)도 오프 상태에서 온 상태로 스위칭되며 휴대용 컴퓨터의 동작전원과 도킹의 동작전원의 연결을 서로 상충되지 않게 조절하므로 홀트발생을 방지할 수 있다.The voltage level of the 'A' point changes from high to low for the predetermined time, and the third transistor TR3 of the switching unit 21 is also switched from the off state to the on state. It is possible to prevent the occurrence of the Hall effect by adjusting the connection of the operation power source so as not to be in conflict with each other.

본 발명에 따른 휴대용 컴퓨터는 사용도중 도킹 또는 리플리케이터등을 연결함으로 인해 발생되는 홀트상태를 방지하여 휴대용 컴퓨터의 전원을 오프 시키지 않고 도킹 또는 리플리케이터등을 연결사용할 수 있는 사용자의 편의를 제공하고 작업능률을 향상시키는 효과가 있다.The portable computer according to the present invention can prevent a holt state caused by connecting a docking or a replicator or the like during use, thereby providing convenience of a user who can connect a docking or a replicator without turning off the power of the portable computer, .
