1. Field of the Invention
The present invention relates a hand-held communication electronic apparatus, more particularly to a compact and easy-to-use hand-held communication electronic apparatus having two sliding keypads slidably stored behind and parallel to a main housing of the apparatus, which can be slid out from the bottom and side of the main housing respectively.
2. Prior Art of the Invention
The original intention to design mobile phone is mainly for a user to communicate with other people at any time. The original design objective of a personal digital assistant (hereinafter referred to as PDA) is to provide a user with a plurality of electronic personal information management (abbreviated as PIM) tools of the functions similar to a personal schedule management, a notebook and a telephone pad etc., that is the reason why PDA is also called as an electronic organizer. However, while the personal computer and communication apparatus being combined together within the recent years, a smart phone is then designed to combine cell phone with PDA functions, which not only be used as a mobile communication tool in speech communication, but also provided with the functions of personal information management, receiving electronic mails, reading electronic news, or downloading information from internet. Therefore, the smart phones are now becoming one of the most popular electronic products.
This kind of smart hand-held electronic apparatus has a display screen, a plurality of keys and an output/input port, which can transmit and exchange data with a computer by means of a communication interface. Hence, there are a variety of interesting computer games being developed and provided in the internet for consumers to download. However, since the design of current electronic products tends to make them more lighter, thinner, shorter and smaller, the dimension of the display screen on the product is seriously limited and the size of keypad on the housing thereof is also deducted within a limited area. Thus, it is harmful to the user's eyes who uses such a small display screen on the smart hand-held electronic apparatus to play computer games and receive electronic mails from internet.
Therefore, how to design a compact and easy-to-portable hand-held wireless communication electronic apparatus not only having two stored keypads, but also having a display screen of an appropriate size is a very important topic in the field that needs to be resolved immediately.
The present invention is to provide a compact and easy-to-use hand-held communication electronic apparatus, which not only has two stored keypads, but also has a display screen with an appropriate dimension for watching. An object of the present invention is to increase the value of the electronic apparatus through applying the characteristics disclosed in the present invention for matching the consumers' needs within the vast and competitive market. The characteristics of the present invention refer to a hand-held electronic apparatus having a display screen and a set of control keys on the surface of a main housing thereof, and a first sliding keypad and a second sliding keypad stored in the main housing, wherein the first sliding keypad is slidably combined with the main housing by means of a first rail so that the first sliding keypad can be stored behind and parallel to the main housing and slid out from the bottom of the main housing in one direction, and the second sliding keypad is slidably combined with the first sliding keypad by means of a second rail so that the second sliding keypad can be stored behind and parallel to the first sliding keypad and the bottom of the first sliding keypad in another direction.
The above and other objects, advantages, and features of the present invention will be understood from the following detailed description of the invention when considered in connection with the accompanying drawings below.
The present invention is a hand-held communication electronic apparatus having two slidable keypads, as referring to FIGS. 1˜4, where the hand-held communication electronic apparatus 1 comprises a main housing 11, a first sliding keypad 12 and a second sliding keypad 13 (as shown in
According to the above-mentioned design, as referring to FIGS. 1˜3, since most of the keys 121 and 131 are installed on the first and second sliding keypads 12 and 13, there are only few important control keys needed to be installed on the the main housing 11. This not only effectively increases the space on the main housing 11 for installing the display screen 111 of a larger dimension or size, but also provide a more comfortable and convenient environment for a user to watch information or play game on the display screen 111. In addition, while the user wants to use the hand-held communication electronic apparatus 1 to answer the phone, he only needs to press the answering key (one of the control keys 112) to go talking. As user wants to use the hand-held communication electronic apparatus 1 to call out or transmit a message, he just needs to pull the first sliding keypad 12 out from the bottom of the main housing 11 and press the keys 121 on the first sliding keypad 12 for inputting the numbers and messages. Furthermore, when the user wants to use the hand-held communication electronic apparatus 1 to process or manage more complicate information or documents, he only needs to pull the second sliding keypad 13 out from the bottom of the first sliding keypad 12 in another direction, enabling him to use the keys 131 on the second sliding keypad 13 for inputting the data and processing documents through cooperating with the display screen 111.
In the present invention, as referring to
In the present invention, as referring to FIGS. 1˜4, the hand-held electronic apparatus 1 may be a mobile phone or a smart phone through combining a personal digital assistant with a mobile phone. On an appropriate position of the main housing 11, there may be installed at least one input/output port 17 (as shown in
Summing up the above, since the keypads of the hand-held communication electronic apparatus 1 disclosed in the present invention are no longer directly installed on the surface of the main housing 11, the space on the main housing 11 for installing the display screen 111 are effectively increased to provide a more comfortable and convenient environment for a user to watch information or play game on the display screen 111.
While a preferred embodiment of the invention has been shown and described in detail, it will be readily understood and appreciated that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention.
