Description

  The present invention relates to an apparatus and a system that share an input / output device by switching a plurality of computers.

  With the remarkable progress of computer processing performance, its use is becoming more widespread. For example, an individual user owns a plurality of computers, and there are increasing opportunities to use the computers in different working environments for each computer. In this case, usually, input / output devices such as a keyboard, a display monitor, and a mouse are connected to a plurality of computers via a switching device to save space and reduce costs. Such a switch is generally called a KVM (K: Keyboard, V: Video, M: Mouse) switch.

  The KVM switch is connected between the input / output device and the plurality of computers, and activates the connection between the input / output device and only one of the plurality of computers. By using the KVM switch, the user can select and use a computer to be connected to the input / output device from a plurality of computers.

  In addition, with the rapid spread of the Internet, intranets, and the like, and a plurality of computers being networked, several computer systems using KVM switches have been proposed.

  When a computer is connected to an external network such as the Internet, problems such as data leakage due to user's own computer misoperation, hacking from an external network, or inflow of computer viruses may occur.

  Therefore, for the purpose of improving security, a computer connected to the Internet and a computer for personal use or a computer connected to an intranet are provided separately, and these are connected to the input / output device via the above-mentioned KVM switch. A computer system has been proposed. In such a computer system, the Internet and the intranet are completely separated, and the user can use a computer for performing work that does not require the Internet or particularly important work, and a computer for using the Internet. It can be properly used according to the content and importance of the work.

  For example, the above-described computer system using a plurality of computers with a set of input / output devices via the KVM switch is advantageous in terms of installation cost and installation space compared to a computer system provided with input / output devices for each computer. There are still some problems, though.

  For example, if the KVM switch is installed near the installation location such as a work desk where a computer or input / output device is installed for the purpose of improving the user's work environment or due to restrictions on the work environment, the user's work area is unnecessary. Will be occupied.

  Alternatively, when the KVM switch is installed at a location relatively distant from the computer or the input / output device, for example, a location that is difficult for the user to see, such as under the work desk or behind the computer, the user's work area can be secured, but the KVM Switching operation of the switch and confirmation of the switching state are very inconvenient. Furthermore, since the cable used to connect the computer and the input / output device via the KVM switch becomes long, for example, the image quality of the display monitor cannot be avoided.

  Furthermore, although it is preferable for the purpose of improving security to properly use a plurality of independent computers through the KVM switch according to the contents and importance of work, it is preferable to transfer data from one computer to another. When transferring the data, it is inconvenient because data must be temporarily stored in a storage medium and the storage medium must be manually replaced with another computer.

  Therefore, in view of the above problems, an object of the present invention is to secure a user's work space and reduce installation cost and to have a security function when sharing an input / output device by switching a plurality of computers. To provide a system.

  In order to achieve the above object, according to the present invention, a computer device with a switching function includes a computer and a switching unit inside a casing of the computer device, and the switching unit is a connection destination of an input / output device of the computer device.
