Field of the Invention The present invention relates to a data processing apparatus, and more particularly to a data processing apparatus which is grouped into a pen type for carrying and operation. [Prior Art] Data processing devices such as desktop computers and laptop computers are playing an increasingly indispensable role in all aspects of modern life. Knee-on computers, also known as portable PCs and notebooks, are typically smaller and lighter than desktop computers, so users can carry them around and use them as active offices. However, laptops are still too large and too heavy to be carried and used in certain environments, for example, for passengers traveling in the economy class of a plane or in the back seat of a small to medium sized private car. The laptop can feel a lot of inconvenience or discomfort. In addition, for passengers traveling by plane or train, the laptop also takes up a lot of space in the carry-on luggage. Personal digital assistant (PDA) devices are usually smaller and lighter than laptops, so In many cases they are more convenient to carry and use on the go. One type of PDA device has a keyboard similar to a miniature laptop keyboard that does not conveniently enter data into pda. Another PDA device has a pressure sensing screen or a touch screen for the user to use a pointed object (such as a user's finger, a pen tip, etc.) to implement data input. This touch screen is expensive and its life cycle is relatively short with -4-200821940. In addition, even if the PDA device is smaller and lighter than a laptop, when it is carried in a pocket or purse The size of the PDA device still looks quite large. Therefore, it would be advantageous to provide a compact and lightweight data processing device. An ideal data processing device should have a simple and intuitive data input mechanism, and of course, for data processing devices, durability and low cost are desirable. Further, if the data processing device can be used in different external environments, it will be more advantageous.
