Description

Integrated device of personal digital assistant and computer

(1) Technical field

The utility model relates to a function expansion device of a computer device, in particular to a device for integrating personal digital assistants and computer functions, so that the data of the personal digital assistant and computer equipment can be shared, and the personal digital assistant can be used to As one of the data input devices of computer equipment.

(2) Background technology

Early personal digital assistants (Personal Digital Assistant, referred to as PDA) are mainly used as records and memos of personal data (such as personal identification data, telephone, address, itinerary, etc.). With the increasing popularity of the use of personal digital assistants, the function of personal digital assistants has changed from an early stand-alone data recording unit to a thin, light and small personal portable computer device. The current commercialized personal digital assistants can perform functions such as surfing the Internet, document editing, and file transmission under the condition of powerful operating system support and application program development.

However, in terms of the current use of personal digital assistants, the focus is still on the single-machine functions. Although the personal digital assistant of newer design has been equipped with various data transmission interfaces (such as USB, PCMCIA etc.) and other expansion slots at present, so that this personal digital assistant can be connected with computer equipment. However, the user still needs to connect the personal digital assistant to the connector of the computer device through the connector and the cable. For general computer users, there are still inconveniences in actual use.

Although some personal digital assistants have a communication interface through infrared (IR) or radio frequency signal (RF) to connect with computer equipment, the computer equipment must be equipped with the same communication interface, and the communication protocol and various The software settings are relatively cumbersome, so it is still inconvenient for ordinary users.

In order to make the use of personal digital assistants more friendly, the industry has designed various connection devices to connect with computers or other devices. For example, U.S. Patent No. 6,266,539 discloses a device that can integrate a personal digital assistant with a telephone (refer to the functional block diagram of the control circuit shown in FIG. 1 ), which is configured with a socket 102 on a telephone 101 , and a corresponding socket 104 is configured in the personal digital assistant 103, so that the personal digital assistant 103 can be inserted in the socket 102 of the telephone 101 through the socket 104 to achieve The physical link between the two. The control circuit inside the telephone 101 includes the circuit functions of general telephone communication, and it can also be combined with an external or built-in data device 105 (modem) (MODEM). With this structure, the telephone set 101 can be connected to the telephone line through a standard connector to perform general telephone communication functions, and the telephone set 101 can also be connected to a data line to perform network digital data transmission , and e-mail transmission function. At the same time, the PDA 103 can also perform data transmission through the telephone communication function. However, this design only combines the personal digital assistant with the communication function of the phone, which still has its shortcomings for actual business needs. For example, as far as personal computers or notebook computers are commonly used at present, there is still no convenient combination device to integrate the functions of the two.

Therefore, if a kind of function that can integrate the function of personal digital assistant and computer equipment can be designed, then for users, there should be substantial benefits.
