Description

Desktop mobile phone {DESK TOP TYPE PORTABLE RADIOTELEPHONE}

The present invention relates to a mobile phone, and more particularly to a mobile phone that can be used not only as a folder type but also as a desk type.

Typically, a small terminal for sound communication refers to a hand held phone, a C-2, a cellular phone, a digital phone, and a PCS phone. Such a small terminal performs a communication function while performing wireless communication with a base station.

Nowadays, these portable terminals are in line with the trend of miniaturization and light weight of electronic components, and the first generation of bar-type mobile phones has become commonplace, and the second generation of flip-type mobile phones has become commonplace. Nowadays, flip-type and third-generation folder-type mobile phones are coexisting and are becoming common. In the future, folder-type mobile phones or more compact portable terminals will come into the spotlight.

A typical bar-type cell phone has a body element, an antenna unit installed at the top of the main body, an earpiece including a speaker under the antenna unit, and an LCD unit installed below the earpiece. LCD unit), a keypad including a plurality of number keys and function keys located below the LCD part, and a microphone unit located below the keypad.

A typical flip type mobile phone (for example disclosed in US Pat. No. 5,629,979) comprises a main body, a flip, and a hinge device connecting the main body and the flip. The main body of the flip-type mobile phone is installed at the top of the antenna device, the ear piece including the speaker is located under the antenna device, the LCD part is mounted below the ear piece, the number of keys and function keys below the LCD part A keypad including a was installed and the microphone device was installed below the keypad.

A typical folder type mobile phone (e.g., disclosed in US Pat. No. 5,628,089) comprises a main body, a folder, and a hinge device for opening and closing a folder to a call angle in the main body. The conventional folder type mobile phone is provided with an antenna device on the top of the main body, a keypad including a plurality of number keys and function keys is installed below the antenna device, and a microphone device is installed below the keypad. The folder that is opened and closed by the hinge device in the main body is located in the ear piece including the speaker, the CD portion is mounted below the ear piece. The LCD may be selectively mounted on a folder or a main body.

Among these bar type, flip type and folder type mobile phones, flip type and folder type mobile phones are becoming more common. The reason why such flip type mobile phones and folder type mobile phones are becoming common is as follows.

The flip-type mobile phone protects a number of keys when the flip connected to the main body in the on-hook state prevents malfunction of the keys, and collects the sound by performing the negative reflector role in the off-hook state. to be. Moreover, the flip type mobile phone is advantageous in miniaturizing the main body since the microphone device can be installed in the flip.

This is because a folder-type mobile phone protects the keypad when the folder connected to the main body protects the keypad when it is in the on-hook state, and collects the sound by performing the role of the negative reflector when the folder is in the off-hook state. . In addition, the folder type mobile phone is a structure that can be attached to the CD or ear piece in the folder, which is more advantageous for miniaturizing the body.

At this time, the current mobile phone is a trend of miniaturization, but the mobile phone has a limitation in miniaturization in order to secure the distance between the user's ear and the mouth. In other words, the distance between the transmitter (microphone) and the receiver (loudspeaker) should be at least 14 cm. Therefore, flip-type or folder-type mobile phones will pursue miniaturization in the future while maintaining communication distance.

However, in view of the use of such a conventional portable terminal, there is a problem in that its utilization is narrow other than voice communication.

For example, if the user is a celery man, most of the day he or she is working in the office, the telephone calls in the office to use the office. At this time, the conventional mobile phone is generally stored in the user's pocket or bag or desk drawer.

Moreover, mobile phones currently on the market have both a clock function and an electronic calculator function. In addition, mobile phones currently on the market have a calendar function as an additional service function. However, the conventional mobile phone was not configured to effectively utilize such a clock function, an electronic calculator function, and a calendar function. The conventional mobile phone configuration provides an inconvenience to the user to use the additional service function.

The present invention has been made to solve the above-mentioned problems, an object of the present invention to provide a desk-type mobile phone that can more effectively utilize the value-added service, including the clock function or calendar function provided in the mobile phone have.

Another object of the present invention is to provide a desk-type mobile phone having a good storage state (can be placed in the stand type).

Still another object of the present invention is to provide a desk-type mobile phone having a desk-type function as well as a folder type.

Another object of the present invention to provide a desk-type mobile phone that can be protected from the external environment.

In order to achieve the above object, the present invention provides a main housing comprising an antenna device and at least one key;

A sub housing having a storage space and a first opening;

First hinge means for mechanically connecting the main housing and the sub housing;
