The present invention relates to a keyboard for connecting a plurality of monitors and / or keyboards to a single computer main body, a monitor router, that is, a keyboard and / or a monitor selection switch for easily selecting a desired keyboard and / or monitor.

In general, when using a computer, one or two computers were installed in a computer room or other place in the office used for work and went to the place where the computer was installed when needed. Thus, the performance of the task was also inefficient.

Of course, if each person installs and uses a computer, such problems can be solved, but the economic burden is increased and the efficient computer cannot be utilized.

In addition, when using computers for education in schools or academies, economically, two people use one computer as a group, and in this case, the educational effect cannot be expected, and in the unstable posture, Operating the keyboard or looking at the monitor adversely affected skeletal formation and visual acuity in growing students.

In general, in a main body, a keyboard, and a monitor constituting a computer system, the cost of the main body is much higher than that of a keyboard and a monitor.

Therefore, the present invention connects a plurality of keyboards and / or monitors to a single computer body, thereby maximizing the usability of the computer, thereby improving work efficiency when used in the office, and the effect of education in schools and academies and students. You can protect your health.

The present invention is to provide a keyboard and / or monitor selection function that can be easily used, will be described below the switch configuration of the present invention based on the accompanying drawings.

In this configuration, however, the number, relative arrangements, shapes, and the like of the components are not limited thereto unless otherwise specified.

FIG. 1 is an external perspective view of the keyboard and / or monitor selection switch of the present invention, the snap button operation of which is independent of the keyboard selection switch 1A, 1B, 1C, which selectively snaps to the plane of the case 7. The monitor selector switches 2A, 2B and 2C are configured respectively.

One side of the case 7 is composed of a keyboard connection jack (3A) (3B) (3C) and the main body keyboard connection jack (4), the other side of the monitor connection jack (5A) (5B) (5C) and the main body monitor connection jack (6) These are each constructed.

2 is a switch connection diagram of the present invention, in which a circuit board having the above connection configuration is provided in the case 7 for a keyboard and a monitor, respectively.

In the figure, a is a connection point of the keyboard selection switch 1A or the monitor selection switch 2A, b is a connection point of the keyboard selection switch 1B or the monitor selection switch 2B, and c is the keyboard selection switch 1C. And the contact point of the monitor selection switch 2C.

A 'is the connection point of the keyboard connection jack 3A or the monitor connection jack 5A, b' is the connection contact of the keyboard connection jack 3B or the monitor connection jack 5B, and c 'is the keyboard connection jack 3C or the monitor connection jack. This is the connection point of (5C).

The jacks of the keyboard connection jacks 3A, 3B, 3C and the monitor connection jacks 5A, 5B, 5C are omitted in the figure, and are identical to the keyboard connection jacks 3C and the monitor connection jacks 5C, respectively.

2 is a connection contact point of the main body keyboard connection jack 4 or the main body monitor connection jack 6;

Reference numerals 8a, 8b, and 8c are keyboard connection display lamps.

According to the present invention of the above configuration, only one keyboard selection switch 1A, 1B, 1C can be selectively used, and the monitor selection switches 2A, 2B, 2C can be used for up to three monitors at the same time. have.

Connect the main body keyboard connection jack (4) and the main unit monitor connection jack (6) to one computer body, and connect the keyboard connection jack (3A) to the "keyboard A" assumed, and the keyboard connection jack (3B) to the "keyboard B" assumed. Connect the keyboard connector jack 3C to the assumed "keyboard C", while the monitor connection jack 5A to the "monitor A" assumed, and the monitor connection jack 5B to the "monitor B" assumed, Connect monitor connecting jack (5C) to C ".

Therefore, if one of the keyboard selection switches 1A, 1B, and 1C is "on", it can be selectively used among the keyboards "A", "B", "C" to be assumed, or the monitor selection switches 2A, (2B). When "2C" is turned on, the monitor "A", "B", "C" to be assumed can be selectively used, or both or both can be used simultaneously.

In the present invention, the keyboard connection line can be extended to 50m, and the monitor connection line can be extended to 30m.

Therefore, it is possible to input and output data even if only the keyboard and monitor are installed, which can solve the inefficiency of the work that has to be moved to the place where the computer is installed, and can expect the efficiency of education in schools and academies, etc. It is a useful design that can contribute.

Claims (1)

A keyboard selection switch (1A), (1B), (1C) for selective snap operation on the case (7), and a monitor selection switch (2A), (2B), (2C) for independent snap operation are configured; Keyboard connection jacks (3A), 3B (3C) and monitor connection jacks (5A) (5B) for incorporating circuit boards that are selectively " on / off " by operation and connecting the on / off operation to respective installed keyboards and monitors. (5C) and the main body keyboard connection jack (4) and the main body monitor connection jack (6) to be connected to the main body can be used to selectively use the three keyboards, characterized in that the three monitors can be used selectively or simultaneously Keyboard and / or monitor selector switch.
