Abstract

PURPOSE: A hard disk selecting device for the multi-user operation is provided to selectively apply a few OS(Operating System) to one computer equipping with a few hard disks, and to construct an independent use region by operating only a switch installed to a computer case if a few users want to use one computer. CONSTITUTION: A hard disk selection switch selects one from the hard disks. A hard disk selection control logic(70) controls the power supply of the selected hard disk by receiving a selection signal from the hard disk selection switch. The hard disk selection control logic operates the power supply connectors(21a-23a) matched with the hard disks, a hard disk selection switch connector(30a), an operation indicating light connector(40a), and a main board power on/off connector(50). If the hard disk selection switch is selected doubly, the hard disk selection control logic cuts off an input signal to an open state by connecting the switch relay input between the hard disk control logic and the main board power on/off connector with the hard disk selection switch.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer hard disk selecting apparatus. In particular, in a computer in which a plurality of hard disks are installed, a computer which can boot and use a computer by operating only a desired hard disk by operating a hard disk selection switch mounted outside the computer case The hard disk selector.

Commonly used computer operating systems include DOS, Windows, Unix, Linux, etc. The conventional computer operating system has a disadvantage in that only one operating system is selected and used for a single computer. Therefore, in the case of using two or more operating systems, there is an inconvenience of deleting an existing operating system and installing another operating system whenever a system operating system is to be changed.

In addition, when a single personal computer is used at home and used by several people, the plurality of users use the computer while accessing only their own hard disk area without exposing the PC use area used by the first user to the second user. The need to do so often arises.

In other words, even when a single computer operating system is used for one computer at home, for example, when a parent and child share a computer at home, the data of the other party often occurs. There is a need for a unique system that can secure unique areas between users.

Accordingly, computer operation techniques have been proposed in which a plurality of computers can be used smoothly by different users for different purposes or in different environments. As a technology for sharing a plurality of hard disk drives in one computer and sharing them among multiple users, the Korean Utility Model No. 20-0229944, the Korean Utility Model No. 20-0238833, and the Korean Patent Publication No. 2000-0054002 Techniques are disclosed.

That is, if the selection signal is generated by the switch operation once and then the selection operation is performed with another switch while the power is still on, there is no latch function of the flip-flop integrated circuit, so that the generated selection signal cannot be maintained. I have it.

On the other hand, the prior art disclosed in Korean Patent Laid-Open Publication No. 2000-0054002 is designed to supply power at all times for the operation of the hard disk selection circuit, and has a problem of power loss due to standby current. In addition, a battery is provided for power supply of the hard disk selection circuit disclosed in the above-mentioned Korean Patent Publication No. 2000-0054002, or a DC power source made through a rectifier circuit has a defect that must be powered.

Accordingly, a first object of the present invention is to provide a computer hard disk selecting apparatus which can selectively apply one computer equipped with several hard disks as several operating systems.

The second object of the present invention is, in addition to the first object, in the case where a plurality of users want to use a computer, a computer hard disk capable of constructing a unique computer use area only by operating a switch mounted on a computer case. It is to provide a selection device.

It is a third object of the present invention to provide a computer hard disk selecting apparatus that prevents computer system malfunction even in a case where a switch for selecting a plurality of hard disks is inadvertently selected in addition to the first object.

It is a fourth object of the present invention to provide a computer hard disk selecting apparatus which solves the problem of the prior art in which unnecessary power consumption is provided by supplying power to the computer hard disk selecting control circuit even in a standby state. .
