The present invention relates to an opening and closing device for an electronic device, and more particularly, a first body assembled with a first cover and a second cover and a second body assembled with a third cover and a fourth cover are slidable, rotatable and rotatable. The present invention relates to a switchgear for an electronic device, which is connected to each other by a composite hinge assembly, and at the same time, mutual interference does not occur when implementing each operation, thereby increasing convenience of use.

Recently, as the prevalence of various electronic devices, especially portable wireless terminals, increases, additional functions that are suitable for the user's taste are required for the portable terminal, as well as simple functions of wireless communication.

In response to these demands, portable terminals have evolved from a general bar type to a flip type, a flip up type, a folder type, and the like. To achieve.

This is because the folder type terminal can secure enough space to adopt a wide liquid crystal display device as a display device, and in particular, because it is folded in half and portable, the portability is superior to other terminals.

On the other hand, it is possible to have a display device having a wide LCD module of a similar size as a folder type terminal, and at the same time, a slide type terminal capable of contributing to the miniaturization of the terminal is known.

Such a slide type terminal has an additional advantage that the sub body corresponding to the cover is opened and closed by a sliding operation on the main body, and is opened and closed by a new operation while maintaining the advantages of the existing folder type terminal.

As such a slide type terminal, a sliding type portable wireless terminal is disclosed in Utility Model Registration No. 2003-0000136.

In the terminal disclosed in the present application, as a guide means for guiding the sub body on the main body, guide slits are formed in the longitudinal direction on both sides of the main plate, and guide ribs slidably coupled to the guide slits are formed on the slide plate.

In the terminal, the guide rib is slid along the guide slit, so that the slide plate and the sub body are linearly opened and closed from the main plate and the main body.

On the other hand, in such a sliding terminal, the sub body having the LCD screen moves in parallel from the main body with the keypad. Therefore, the keypad and the LCD screen always maintain 180 degrees in parallel.

By the way, when the user uses the LCD screen of the terminal to receive texts or to enjoy the video through the terminal, the user places the terminal in front of him and alternates between the keypad of the main body and the LCD screen of the sub body. Or, the inconvenience of having to hold the LCD screen of the terminal facing the front for a long time is caused. That is, the distance from the user to the terminal is about 40 cm, and the opening angle between the main body and the sub body from the user's eyes is about 20 degrees. Therefore, even in this case, it is most convenient for the terminal to maintain an opening angle of about 160 degrees. However, the conventional sliding type terminal has an opening angle of 180 degrees of the main body and the sub body, so that the user may feel uncomfortable even when viewing the LCD screen.

In order to solve this problem, the main body and the sub-body are slid and the terminal is configured to be rotated at the same time, it is used and developed, but the sliding and the rotation is operated simultaneously, the main body and the sub-body can be rotated during the call in the sliding state, Inconvenience is caused.

An object of the present invention devised in view of the above point is that in an electronic device in which a first body and a second body are assembled, the first body and the second body are slid to each other so as to increase the convenience of use. The present invention provides an opening and closing device for an electronic device that is rotatable about a rotation axis that forms a right angle with respect to a rotation axis in a state where the rotation is performed by a predetermined angle or more.

In addition, another object of the present invention is to prevent the sliding and rotation of the first body and the second body at the same time, so that the rotation is possible only when the second body is rotated more than a predetermined angle relative to the first body. In order to provide an electronic device opening and closing device to increase the ease of use.

Switching device for an electronic device for achieving the object of the present invention as described above, the first body and the second body is positioned so that one side is in contact with each other; One side is supported on the first body so that the second body is slidably and rotatable relative to the first body and rotatable relative to a rotation axis line perpendicular to the rotation axis line. The side is a composite hinge assembly supported on the second body; Anti-rotation means formed in the compound hinge to prevent sliding and rotation at the same time when the second body is slid and rotated relative to the first body; And anti-rotation means formed in the compound hinge to constrain the second body to be rotatable only when the second body is rotated by a predetermined angle or more with respect to the first body, thereby providing the first body and the second body. The electronic devices are slid, folded, and rotatably connected to each other, and sliding, folding, and rotation are interlocked only when a predetermined condition is established.
