Detachable supplementary apparatus for portable communication device

The present invention relates to a detachable auxiliary function device for a portable communication device, and more particularly, to an auxiliary function device that is attached to a detachable existing communication device to expand the function of the portable communication device.

In portable communication devices such as mobile phones, new functional devices are often added according to model changes, and the speed of change is also very fast. An example of a newly added function is an infrared interface for computer communication. Changing a mobile phone to add such a new functional device is not only costly but also a waste of resources. Therefore, a method for adding such a functional device using an existing mobile phone is required.

In addition, as portable communication devices become smaller and lighter, there are cases where a user wants a more heavy and handheld communication device. Of course, using an older communication device may achieve this goal, but in that case there are disadvantages in that many new functions are not available. Therefore, there is a demand for an auxiliary device capable of making various communication devices available, but also making them a heavy and hand-held communication device.

In recent years, the influence on the human body by the radio wave of a mobile phone becomes a problem. When the mobile phone is used in the state where the antenna is drawn out, many effects have been proposed to automatically extract the antenna. However, such a device cannot be used in a conventional mobile phone, which is very inconvenient.

The present inventor has proposed a device for automatically withdrawing and withdrawing an antenna from a conventional mobile phone in Korean Utility Model Application No. 1998-020118 (Utility Model Publication No. 1999-004098). However, this device has the disadvantage that only the antenna is automatically withdrawn or withdrawn and the call button or end button must be pressed separately to make or end a call. Therefore, there is a demand for an auxiliary device that can automatically withdraw or withdraw an antenna during a call, and at the same time have an effect such as automatically pressing a call button or an end button.

The present invention has been made in view of this point, and an object thereof is to provide an auxiliary function device which can add a new function device while using an existing communication device as it is.

Another object of the present invention is to provide an auxiliary device capable of making various communication functions of the existing communication device into a heavy and hand-held communication device.

Another object of the present invention is to provide an auxiliary device which can automatically withdraw or withdraw an antenna at the time of a call or at the end of a call in the existing mobile phone, and at the same time automatically press the call button or the end button. will be.
