Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic notebook, and particularly to a handwritten input method.

[Prior Art] The circuit configuration of a conventional electronic notebook is shown in FIG. Handwritten data input from the handwriting input touch panel 1 is recognized by the recognition means 4 via the control circuit 2. Then, the recognized results are input to the memory circuit 3 and displayed. In other words, handwritten input data is converted into a certain code and input into the memory circuit. It is then displayed through a character generator.

[Problems to be Solved by the Invention] However, the above-mentioned conventional technology requires a huge amount of data for recognition and requires complicated recognition processing. As a result, the recognition process itself requires a large load and is extremely expensive.If implemented in a mobile-sized electronic notebook, the processing speed is extremely slow, and even if input is done by hand, the results are slow to appear, making it extremely difficult to use as a product. That was a problem.

[Means for Solving the Problems] The electronic notebook of the present invention includes a handwriting input touch panel that has a handwriting input section divided into a plurality of electrodes and outputs on-off signals of the plurality of electrodes, Consists of a memory circuit that has a memory that corresponds one-to-one to the electrodes, a control circuit that controls the memory circuit to sequentially write the output signal of the handwriting input touch panel, and a display circuit that displays the handwritten data stored in the memory circuit. characterized by things.

[Function] According to the above configuration of the present invention, data input by hand is stored in the memory circuit as is, and the data is displayed.

[Example] FIG. 1 shows the circuit configuration of an electronic notebook of the present invention. The handwritten input data is sent to the control circuit 2 through the handwritten input touch panel 1 and written into the memory circuit 3 corresponding to the handwritten input touch panel 1.

The data written in the memory circuit 3 is then displayed on the display device 4. In other words, it is stored exactly as it was written by hand. When that area is complete, I turn to the next page and write on it. It feels exactly the same as writing in a regular paper notebook. Besides that I! A diagram is shown in FIG. Furthermore, in the present invention, data written by hand is displayed on the display device, but as shown in Figure 3, it is very easy to send that data to a personal computer, and the data is recognized and aggregated by the personal computer. It's easy to do.

In addition, in Figure 3, the connection between the electronic notebook and the computer is performed using a cable, but various methods can be realized, such as exchanging data by light using an LED, etc., or exchanging data wirelessly using an FM transmitter.

[Effects of the Invention] According to the configuration of the present invention as described above, since the data written by hand is stored as is, a recognition processing device and recognition data are required, and it can be realized with a very small circuit scale. Therefore, it becomes easy to downsize the electronic notebook and it can be realized at low cost.

Moreover, since recognition processing is not required, the response after handwriting is extremely fast, and handwriting input itself can be performed smoothly. In conventional handwriting recognition, a large number of erroneous recognitions occur and it takes considerable time to correct them, but with the configuration of the present invention, there is no need for recognition processing because the electronic notebook itself does not perform recognition processing. As explained above, this can be done very easily by connecting to a computer, sending the data, and then having the computer do the recognition, data processing, etc.
