     BACKGROUND OF THE INVENTION  
      Our life has entered into a booming technological development stage for the electronic information industry. As the technologies related to various high-tech products derived from computers, mobile communication products, and telecommunication networks advance, many high-tech products and mobile communication products come with smaller sizes, more comprehensive functions, and lower prices. Such products become popular; in particularly, the popular mobile phone is closely linked to our daily life. The extensive use of mobile telecommunication products shortens the distance and the time between people. As various telecommunication products are introduced continuously into the market, people have higher demands on the functions of telecommunication products. In the future, a telecommunication product can provide a more convenient, more effective, and more diversified function or service, which is also an important index for evaluating whether or not the manufacturing technology of such telecommunication product leads others in the industry.  
      More and more mobile phones come with different functions such as sending or receiving short messages, connection to Internet, storing telephone numbers, setting telephone modes, editing ring tones, and installing screensavers and calculators, etc., so that users can click on their desired option among different functions as needed. However, installing too many functions in a mobile phone causes inconvenience to certain people such as children. Children usually are not familiar with the operation of a mobile phone with too complicated functions, and do not need a mobile phone with too complicated functions. Therefore, it has been a long-time goal for the telecommunication manufacturers to find a way of designing a low-cost and simple-to-use mobile phone for children.  
     SUMMARY OF THE INVENTION  
      In view of the above description, children usually are not familiar with the operation of a mobile phone with too complicated functions and do not need a mobile phone with too complication function, the inventor of the present invention based on years of manufacturing experience and skills to conduct extensive researches, experiments, and improvements to solve the foregoing problem and finally invented a personal handphone system (PHS) handset for children in the hope of overcoming the shortcomings of the prior arts.  
      The primary objective of the present invention is to provide a personal handphone system (PHS) handset for children; wherein a plurality of indicating lamps and a plurality of drawings corresponding to the indicating lamps are disposed on a panel of the handset, so that each indicating lamp corresponds to a drawing; a plurality of arrow keys and an enter key are disposed on one side of the indicating lamp for selecting the indicating lamp, and a lit indicating lamp can be selected by controlling the foregoing arrow keys; a telephone number corresponding to an indicating lamp is stored in a memory of the handset, so that when a phone call is dialed from the handset by pressing the arrow keys to move the lit indicating lamp next to a drawing corresponding to the desired telephone number and pressing the enter key, a microprocessor of the handset reads the telephone number corresponding to the code of the indicating lamp from the memory and dials that telephone number. Such arrangement allows children to make phone calls very easily, and children are no longer afraid of being unfamiliar with the operation of mobile phones. In the meanwhile, the handset no longer needs to build complicated function keys on the handset or code program drivers for the complicated functions, and it thus lowers the manufacturing cost of the handset.  
      Another objective of the present invention is provide a personal handphone system (PHS) handset for children; wherein the enter key of the handset serves as a hang-up key for hanging up a phone call by pressing the enter key during a phone call, such that the microprocessor of the handset will disconnect a phone call according to the code of enter key.
