[Prior Art] In conventional information equipment, such as personal computers, display cathodes, rays, and
A tube (CRT) was connected, and one display unit was connected to two computer bodies. General desktop computers are rarely carried around and used in a fixed manner, and there is no need for the display itself to switch between various types of display; once fixed, it remains in a fixed position. It was common sense to make full use of the machine itself.

[Problems to be Solved by the Invention] The present invention solves the problem that the situation in which conventional information devices themselves are used has changed, and machines that were previously fixed types are now portable and can be moved to any location. It's coming. The range of applications has been expanded by making it smaller and lighter, and it can be used to operate a thin liquid crystal display as a display, or to operate a CRT display at the other user's location while the computer's display itself is operating at the destination. The way they are used has changed, such as when connecting to display the operating status to the user at the same time, or when there is a large audience, the display is enlarged on a wall and information is transmitted to an unspecified number of members. To summarize the situation, it can be said that this is due to the development of the shape and structure of the devices themselves, and further changes are occurring in the way and environment in which devices are used.

Assume that a CRT is connected to the connector 8 and the slide switch 9 is left in position 2 because the slide switch 9 is not operated. The output waveform is as shown in FIG. 4 <0 to 0 for CRT. OHP where 8 volts (V) is to be supplied
There is a risk that the CRT will be destroyed because it outputs 0 to about 3.5cm, but as explained in (c) above, the signal line 43 is NC, so there is no abnormal voltage at the output terminal. ,
15′! Even if you slide the switch 9 with the load connected, it will not be damaged, and even if you use it properly, the slide switch uses mechanical contacts, so it will not break during the sliding process. 2 fi in poetry
It is possible that the contacts are in contact with each other, so this safety mechanism is designed with this in mind. Conversely, when you connect an OHP to the connector and set the switch to 3, it is approximately 0.8
There is no problem because ■ is added. As explained above, the present invention is not simply about attaching a convenient terminal to the back of an information device. It not only satisfies the operator himself, but also convinces third parties around him, or at the same time conveys information. The configuration in which it is provided has a great effect.
