[0040] Please refer to image 3 , which shows a schematic diagram of the structure of the optical pen according to the first embodiment of the present invention. The optical pen 30 of the first embodiment at least includes a casing 301 , an actuating mechanism 303 , a first optical module 305 and a wireless transmitter 307 . The housing 301 has a front part 301a and a tail part 301b, and the front part 301a and the tail part 301b are separated by a preset length L1. The actuating mechanism 303 is mostly disposed on the front portion 301a of the casing. When the user activates the actuating mechanism 303 to use the optical pen 30, the actuating mechanism 303 sends an activation signal. There are various kinds of practicable actuating mechanism 303, for example: actuating mechanism 303 is an annular sleeve surrounding the housing front portion 301a, which allows the user to hold the optical pen 30 at any angle, and the annular sleeve Both tubes can detect whether the optical p...

[0048] Please refer to Figure 4 , which shows a schematic diagram of the structure of the optical pen according to the second embodiment of the present invention. The optical pen 40 of the second embodiment is similar in structure to the optical pen 30 of the first embodiment. In the optical pen 40 of the second embodiment, in addition to setting the first optical module 305 at the rear part 301b of the casing 301, the second optical module 402 is also arranged at the front part 301a; and the wireless transmitter 307 in the casing 301 is connected with the first optical module The module 305 and the second optical module 402 are electrically connected. As for other components of the optical pen 40 that are the same as or similar to those of the optical pen 30 in the first embodiment, details will not be repeated here.
[0049] The optical pen 40 of the second embodiment is provided with an optical module at both the front part 301a and the tail part 301b of the pen. During ...

[0061] Please refer to Figure 6 , which shows a schematic diagram of the structure of the optical pen according to the third embodiment of the present invention. The optical pen 60 of the third embodiment at least includes a housing 601 , an actuating mechanism 603 , a first optical module 605 , an angle detecting module 606 and a wireless transmitter 607 . The structure of the optical pen 60 of the third embodiment is similar to that of the optical pen 30 of the first embodiment, except that the optical pen 60 is equipped with an angle detection module 606, which is electrically connected with a wireless transmitter 607, and can detect the optical pen. 60 is the vertical tilt angle and horizontal rotation angle in space. Through the conversion between the position and the angle of the tail of the optical pen 60, the position of the front 601a can be deduced to achieve a more accurate writing effect.
[0062] In this embodiment, the angle detection module 606 includes a fir...
