Digital electronic pen

Abstract

The invention discloses a digital electronic pen which is used for writing on a piece of ordinary digital paper and recognizing the writing. The digital electronic pen comprises an ordinary writing pen, a writing picking-up camera (1) and a core circuit; the core circuit is arranged in the ordinary writing pen; the ordinary writing pen is internally provided with a refill used for finishing ordinary writing; the core circuit comprises a microprocessor (2), a memory (3) and a USB transceiver (4); the output end of the writing picking-up camera (1) is connected with the microprocessor (2); the microprocessor (2) is connected with the memory (3) through an internal bus; and the microprocessor (2) is also connected with the USB transceiver (4). When the digital electronic pen is used for writing and leaves the ordinary ink writing, the microprocessor can obtain the writing data according to the information picked up by the writing picking-up camera and stores the writing data in the memory, and the USB transceiver can be connected with a computer to transmit the writing data into the computer to be stored and read. The digital electronic pen disclosed by the invention has the characteristics of being convenient to use and safe and reliable.

Description

technical field [0001] The invention relates to a digital electronic digital pen. Background technique [0002] At present, with the rapid development of science and technology, people's dependence on data is getting higher and higher. For example, a large amount of information data such as information records, communication records and work records must be recorded. In particular, some sensitive information records, such as financial, contract and legal signature records, as well as some records in specific environments, need to be kept for a long time for future viewing. Ordinary pen and paper are easy to use and carry, but they cannot achieve the purpose of long-term storage, and the storage, query and transmission of data are limited by themselves. [0003] Today's computers are good at recording, storing, querying, and transferring data, but data cannot be processed until it enters the computer. However, using a computer to record data at any time is obviously not sui...
