The present invention relates to a mobile phone, and more particularly, to a blind mobile phone that pursues the convenience as well as the convenience of daily life like the general public.

Due to the development of various communication facilities, portable wireless telephones have been used in recent years, and the development of the electronics industry has led to the miniaturization of portable wireless telephones with reduced weight and volume as the electronic components have been increasingly miniaturized, thereby achieving multi-functionality.

In recent years, the social structure has changed so as to be unable to live without a telephone in daily life, and according to this information trend, users can easily obtain various useful information.

In addition, the types of telephones are gradually gradually layered, and the portable wireless telephones capable of making calls while still and moving, the digital telephones capable of transmitting and receiving voice and non-voice information simultaneously, the still and moving telephones capable of transmitting and receiving video signals, and buttons Voice recognition phones that can be spoken instead of pressing, and a variety of other specialty phones are being commercialized.

In the future, when a comprehensive information communication network is established, all information desired by a telephone call can be obtained, and it will also be a high-tech information age that can be easily used by anyone, anytime, anywhere and only by voice.

At this point, as shown in FIG. 1, a typical conventional portable radiotelephone which is used by the general person visually sees the portable radiotelephone 100 in plan view, and transmits signal transmission and reception input signals of various transmission outputs at the upper end. An antenna 11 (antena) for input is located, and a speaker (12) speaker is positioned under the antenna 11, and an LCD unit 13 (LCD) unit for outputting various signals is provided under the speaker 12. Under the LCD 13, a volume control function key button 16, a numeric function key button 17 part, and a special function key button 15 part are formed to indicate various inputs.

Also, from the bottom, a subscriber identy module (SIM) connection 19 is located, and a battery pack case 21 for protecting the battery and a locker 20 for detaching the battery pack case 21 are formed.

The SIM card installed in the SIM connection unit 19 is provided to the general public as needed. (It is not necessary for an analog cell phone and is essential for GSM / PCN / CDMA).

In the antenna 11 of the portable radiotelephone, as disclosed in Korean Utility Model Publication No. 94-957 (Power on / off device using the antenna of the portable radiotelephone: Samsung Electronics), When the antenna (11: telescopic antena) simply folds or unfolds the antenna has been invented a mobile phone that implements the ON / OFF function of the power switch automatically.

When the schematic configuration of the present invention is described, a push rod is formed at the lower end of the antenna sliding to one end of the main body of the portable radiotelephone, and the push-type antenna is folded or unfolded by providing a push switch to contact the push rod. In this case, by automatically contacting and detaching, it functions to transmit signal of transmission output and receive input signal. Therefore, the power switch is turned on or off. As a result, it is easy to operate the power switch even in low light, and moreover, blind people can turn the phone on and off by itself.
