Optical induction type hand-written input device

Abstract

This invention is a sort of optics induction type hand-written import device, it consists of the shell, the pen-core, the circuit plank, the video information communicating module, and the sport checking module. This pen-core is fixed in the shell and it has a pen-neb, the pen-neb comes out the lower extreme of the shell or it is hided in the shell. This circuit plank is fixed in the shell and it locates the one side of the pen-neb. This video information communicating module and the sport checking module are fixed in the shell and they are connected with the circuit plank. Thereby this optics induction type hand-written import device checks the traveling locus of this optics induction type hand-written import device by receiving the reflection signal which casts to the checking face, and it imports the traveling locus to the digital electron device in order to form the handwriting by identifying the traveling locus.

Description

technical field [0001] The present invention relates to an optical induction type handwriting input device, especially an optical device that detects the moving track by receiving the reflected light projected on the detection surface, and forms the handwriting by identifying the moving track and inputting the moving track into digital electronic equipment. Inductive handwriting input device. Background technique [0002] Known handwriting input devices for computers are usually a magnetically sensitive handwriting digital board with a sensor pen; or, a handwriting digital board with LCD display and a sensor pen. [0003] Please refer to FIG. 1 , which is a schematic diagram of a conventional magnetic-sensing handwriting digital board combined with an inductive pen. As can be seen from the figure, when the handwriting digital board B of this kind of public magnetic induction (hereinafter referred to as "common magnetic handwriting board") is in use, since the sensing pen P ...

AI Technical Summary

Problems solved by technology

However, its cost is extremely high and expensive, and ordinary users cannot afford it.

[0006] Furthermore, no matter which of the above methods is used, it needs to cooperate with a handwritten digital board, which not only increases the cost, but also causes inconvenience for users to carry.

[0007] Therefore, it can be seen from the above that the currently known related handwriting input devices obviously have inconvenience and lack, and need to be improved.
