ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electronic computer with a file bay cover including an electronic lock and a method of controlling the same.
The spread of electronic computers has recently derived even personal computers owned by individual persons and has accelerated the development of general software. Today, a variety of operating systems (OSs) and other software for promoting easy installation of the general software in computers are available. Easy installation, however, is apt to render a computer system unstable due to operator's careless installation work. In fact, careless installation often affects the OS software and other general software loaded in a computer.
In a personal computer, for example, careless installation is likely to overwrite or destroy other general software loaded in the computer. Also, in a network environment implemented by, e.g., the Internet, when the computer system of a provider or similar enterprise collectively managing an information network becomes unstable, it is apt to damage existing customers in the network environment.
Moreover, the prerequisite with a computer possibly used by a plurality of persons in an enterprise is that confidential information be prevented from leaking to the outside in the form of a floppy disk (FD) or similar removable medium. To meet this requirement, there is an increasing demand for a computer capable of rendering temporarily unusable a CD-ROM drive, FD drive or similar drive unit dealing with removable media, i.e., capable of implementing a collective security system.
In light of the above, it is a common practice with an electronic computer to cover a file bay, i.e., a space for accommodating a CD-ROM drive, an FD drive and other drive units with a cover or file bay cover including a lock. The file bay cover is mounted on the computer in such a manner as to cover the drive units including the CD-ROM drive and FD drive. However, the conventional file bay cover with a lock is implemented by a physical lock. As a result, in an enterprise, for example, in which hundreds of computers are operated daily, a great number of locks are required, complicating the management of file bays.
To render the CD-ROM drive and FD drive unusable, a password for entering a BIOS (Basic Input/Output System) setup menu and replacing the conventional physical lock may be input on the computer, as also proposed in the past. However, locking relying on a password practically invalidates the function of the FD drive and limits even the reading operation of the FD drive. In addition, the CD-ROM drive and FD drive cannot be rendered usable or unusable unless the entire function of the computer is shut down for a moment.
Technologies relating to the present invention are disclosed in, e.g., Japanese Patent Laid-Open Publication Nos. 4-327666, 5-5375, 9-30613 and 9-73492 as well as in Japanese Patent No. 2, 741, 726.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an electronic computer with a file bay cover including an electronic lock, which is capable of enhancing the efficiency of a centralized management and security system.
An electronic computer of the present invention includes a file bay cover for covering a file bay accommodating a drive unit that deals with a removable medium, and includes a lock for selectively locking or unlocking the file bay cover and a sensor responsive to closing of the file bay cover. The lock is opened by electronic control. BRIEF DESCRIPTION OF THE DRAWING
