Retractable writing electromagnetic pen

technical field

The present invention relates to a writing type electromagnetic pen, in particular to a retractable writing type electromagnetic pen. During the operation of the pen, the circuit of the electromagnetic pen is automatically activated or deactivated at the most appropriate time to realize a tendency towards Humanized design.

Background technique

The writing type electromagnetic pen is a pen tool that can be used as a general ink pen for writing and has the function of an electromagnetic pen. The writing electromagnetic pen is often used in conjunction with a digital receiving board or a handwriting board during the writing process. In addition to directly writing on ordinary paper as a pen tool, the electromagnetic pen can also store the written content as digital data through the digital receiving board or handwriting board at the same time, so that the user can immediately understand the content of the note or smear through the paper, and the digital data is It is convenient for future organization and editing. Because this type of writing electromagnetic pen is not directly connected to the computer during the writing process, but the data is stored in the memory of the digital receiving board or the handwriting board, and the paper is covered on the digital receiving board or the handwriting board, when the paper When a written pattern or text appears on the screen, it does not mean that the digital receiving board has received the data. At this time, it may be that the switch of the writing electromagnetic pen is not turned on, so that the digital receiving board has not received the data. In order to overcome and prevent this problem, some manufacturers choose to keep the writing electromagnetic pen on whether it is in use or not, which will cause waste of battery power. Therefore still adopt aforementioned method, although the electric power consumption of writing type electromagnetic pen is very little, in order to maintain longer service time, battery also can't be selected for use smaller battery, makes the volume and the weight of pen can't reduce like this. In view of this, there is a need for an improved structure of the electromagnetic pen, so that the user can activate the writing electromagnetic pen according to the writing habit of a general pen.
