And the first direction is perpendicular to the second direction 0. [Embodiment] The present invention discloses a pointing device having a shockproof function. To make the description of the present invention more detailed and complete, reference is made to the following description in conjunction with Figures 2, 3A, 6 200941870 and Figure 3B. Referring to Figures 2, 3A, and 3B, there is shown a structural view, a perspective view, and a side perspective view of the pointing device in accordance with an embodiment of the present invention. As shown in FIG. 2, the indicating device includes a first electromagnet module 200, a second electromagnet module 202, a laser body 204, a sensor 206, a battery 208, and a switch 210. The battery 208 is electrically connected to the switch 210, the first electromagnet module 200, the second electromagnet module 202, the sensor 206, and the laser body 204. The user controls the power on/off of the laser body 204 by the switch 210, and controls the power supply to the sensor 206, the first electromagnet module 200, the second electromagnet module 202, and the laser body 204. The power supply. The first electromagnet module 200 and the second electromagnet module 202 are electrically connected to the sensor 206 for back-compensating the laser body 204 according to the signal of the sensor 206. Details on this will be described in Rear. 3A, 3B, wherein FIG. 3A is a perspective view of the pointing device 300 as viewed from the X-Z plane. Figure 3B is a side perspective view of the pointing device 300 as viewed from the X-Y plane. The pointing device 300 includes a housing 302, a laser body 204, a sensor 206, and a first electromagnet module 2A. The housing 302 has an exit window 3022. The laser body 204 has a light emitting end 3042 and a fixed end 3044 opposite the light emitting end 3042. Referring to FIG. 2, FIG. 3A, FIG. 3B, when the user presses the switch 210, the battery 208 provides the power of the laser body 204, so that the Ray 200941870 shot body 204 emits a laser light from the light-emitting end 3042, and then the laser light passes through the light-emitting window. At 3022, it is directed toward an indicator (not shown) in the Z direction. The fixed end 4304 is fixedly disposed in the outer casing 302, and the light emitting end 3042 is movably disposed in the outer casing 302. When the user uses the indicating device 3, the light emitting end 3042 may slightly shake in the outer casing 302. When the sensor 206 detects the first displacement of the light-emitting end 3042 in the first direction (ie, the X direction), the sensor 206 generates a first signal (which may be a voltage signal or a current signal) corresponding to the first displacement. . It is worth mentioning that the sensor 206 can directly measure the first displacement or indirectly derive the first displacement by other means. In addition, the first electromagnet module 200 is electrically connected to the sensor 206, and the first electromagnet module 2 is disposed on opposite sides of the inner peripheral wall of the outer casing 3〇2 corresponding to the first direction (X direction). The position of the light emitting end 3042 is located between the first electromagnet modules 2A. The light-emitting end 3042 further has a metal component 3046 disposed on the outer peripheral wall of the light-emitting end 3042 for generating a magnetic field by the first electro-magnet module 200, thereby generating a magnetic force of attracting or repelling the metal component 3〇46 to emit light to the laser body 204. The end 3〇42 is inversely compensated for the first displacement of the parent direction. It should be noted that the metal component 3040 is comprised of a material that can be attracted or repelled by magnetic force. The sensor 206 transmits the first signal to the first electromagnet module 2 according to the first signal generated corresponding to the first displacement in the X direction. Next, the first electric 200941870 magnet module 200 generates a magnetic field according to the first signal, and generates a magnetic force of attracting or repulsing the first displacement of the metal component 3046 disposed on the outer peripheral wall of the light emitting end 3042 of the laser body 204 to the light emitting end 3042. Make an equal displacement compensation for the first displacement. Preferably, the 'first direction (X direction) is perpendicular to the direction of the laser light (i.e., the Z direction). As shown in FIG. 3A, for example, when the user moves the pointing device 3, the light-emitting end 3042 follows the swaying direction in the casing 3〇2, causing the emitted laser light to be at a distance from the wire 卩 3G22. If the distance of i centimeters is _cm, there will be a 1 cm offset from the exit window 3022 at 5 meters. When the sensor 206 detects that the light-emitting end 3 〇 42 is offset by 0.02 cm in the first direction (ie, the χ direction), the sensor responds to the first displacement (ie, offset 〇〇 2 cm) to generate a --signal ( Can be a voltage signal or a - current signal. The sensor 206 transmits the first signal according to the first signal corresponding to the first displacement in the χ direction, and transmits the first signal to the first electromagnet mold, as shown in FIG. 2 . Then, the electro-magnet module 200 generates a magnetic field according to the first signal, and generates a magnetic force for the metal component disposed on the light-emitting end of the laser body 204, and compensates the displacement of the _cm in the first direction to achieve Compensating for the effect of the first displacement offset in the first direction. As shown in FIG. 3B, a second electromagnet module 2〇2 may be further included to compensate for the second displacement in the second direction (ie, the Y direction). When the first electromagnet module 200 reversely compensates the first direction displacement of the light emitting end 3042, the second electromagnet module 202 of the sensor 2〇6 simultaneously detects the light emitting end 3042 in the second direction (ie, Y). The second displacement of the direction, the sensor 206 corresponds to the second displacement to generate a second signal. The second electromagnet module 202 is electrically connected to the sensor 206, and the second electromagnet module 202 is disposed on the opposite sides of the inner peripheral wall of the outer casing (10) 2 corresponding to the second direction (γ direction). Between the second electromagnet module 202, the metal component 3046 generates a magnetic field for the second electromagnet module 202, thereby generating a magnetic force for attracting or repelling the metal component 3046 to the light emitting end 3042 of the laser body 204 in the Y direction. The second displacement is used for reverse compensation. Preferably, the metal component 3046 is comprised of a magnetically attracted or repellent material. The sensor 2〇6 transmits a second signal generated corresponding to the second displacement in the Y direction, and transmits the second signal to the second electromagnet module 202. Next, the second electromagnet module 202 generates a magnetic force of attraction or repulsive to the second displacement of the outer peripheral wall metal component 3046 disposed on the light emitting end 3042 of the laser body 204, so as to make the opposite of the second displacement of the light emitting end 3042. Compensation for displacement. Preferably, the first direction (i.e., the X direction) is different from the second direction (i.e., the Y direction), and the first direction is perpendicular to the second direction.
