Embodiment
See also shown in Figure 1ly, be system architecture synoptic diagram of the present invention.This system architecture comprises: be arranged at CD-ROM drive motor 110, lens moving mechanism 120, lens devices 130 on the portable terminal 10.When the mobile subscriber uses laser pen, rotate by the push button exciting CD-ROM drive motor on the portable terminal 10 110, and then CD-ROM drive motor 110 drives lens moving mechanism 120 work, be used to adjust the lens devices 130 of laser pen laser beam spot size because the induced effect of lens moving mechanism 120, begin to adjust the focal length of laser beam, thereby adjust the size of laser beam spot.
CD-ROM drive motor 110 can be stepping motors.
Working mechanism of the present invention is as follows:
1, in the time of the portable terminal mobile phone power-on, software initialization, device is got back to initialized position thereby stepping motors drives lens moving mechanism work drive lens, and laser beam can be throwed a very large hot spot a long way off by behind the lens devices of initialized location.Like this, the energy of laser is just very little on the unit projected area, if this time, laser beam irradiation just can not be dangerous to people's eyes unintentionally.
If 2 users need point to certain object with laser pen when speech, or certain figure on the screen, can activate CD-ROM drive motor by button, the work of drive motor lens moving mechanism is moved with the position of carrying out that has lens devices, thereby adjust the focal length of laser beam, realize adjusting the size of hot spot.
According to this working mechanism, the user can adjust to the size of the hot spot of laser beam the size of what he referred to object, and spectators just can open-and-shutly see the object of indication like this.
See also shown in Figure 2ly, be electrical block diagram of the present invention.In Fig. 2, operation push-button 210 links to each other with the CPU 220 of portable terminal, the pin GPIO1 of CPU 220 is connected to selector switch 240 by triode 230, and another pin GPIO3 of CPU 220 directly is connected with selector switch 240, and selector switch 240 is connected with CD-ROM drive motor 110.
According to shown in Figure 2, can draw: in the time of KeyUp in user's push button 210 or KeyDown key, CPU 220 can respond, and GPIO1 puts height with pin, triode 230 conductings that are connected with this pin GPIO1 so, and CD-ROM drive motor 110 can be rotated.
If what the user pressed is the KeyUp key, CPU 220 can be set to height to pin GPIO3 so, the A pin of selector switch 240 and the conducting of V1 pin so, and H1 pin and the conducting of V2 pin, CD-ROM drive motor 110 is rotated in the forward;
If what the user pressed is the KeyDown key, so CPU 220 can be set to pin GPIO3 low, the A pin of selector switch 240 and the conducting of V2 pin so, H1 pin and the conducting of V1 pin, CD-ROM drive motor 110 reverse rotations.
See also shown in Figure 3ly, be method flow diagram of the present invention.Shown in Fig. 1,2, this process flow diagram comprises the steps:
Step 301, laser pen KeyUp or KeyDown key produce interrupts;
Step 302 is judged laser pen whether just at work, if, execution in step 304, if not, execution in step 303;
Step 303, CPU detects interruption, and CPU does not respond;
Step 304 judges that further the key that the user presses is KeyUp key or KeyDown key, if the KeyUp key, then execution in step 306, if the KeyDown key, then execution in step 305;
Step 305, GPIO1 is changed to height with pin, and pin GPIO3 is changed to low, and then this moment, CD-ROM drive motor began reverse rotation, and focusing lens moves down, and the hot spot of laser pen laser beam diminishes;
Step 306, GPIO1 is changed to height with pin, and pin GPIO3 is changed to height, and then this moment, CD-ROM drive motor began to be rotated in the forward, and focusing lens moves up, and it is big that the hot spot of laser pen laser beam becomes.
See also shown in Figure 4ly, be a system reference figure of the present invention.In this Fig. 4, generating laser 140 is used to produce laser beam; CD-ROM drive motor 110 drives lens moving mechanisms 120 work, lens moving mechanism 120 drive lens devices 130 on the laser beam transmit direction away from or near moving, to realize adjusting the spot size of laser beam.Wherein, lens moving mechanism 120 is fixedlyed connected with lens devices 130; Lens moving mechanism 120 can be screw machanism; Lens devices 130 comprises lens 1301 and lens fixed support 1302, and wherein lens fixed support 1302 and screw machanism 120 is threaded.
See also shown in Figure 5, the synoptic diagram during for small light spot of the present invention.Shown in Fig. 1,2, the situation of small light spot: the user regulates the KeyDown button, the CD-ROM drive motor reverse rotation, and lens moving mechanism drive lens device moves down, and laser beam forms less hot spot at far-end.
See also shown in Figure 6, the synoptic diagram during for large spot of the present invention.Shown in Fig. 1,2, the situation of large spot: the user regulates the KeyUp button, and CD-ROM drive motor is rotated in the forward, and moves on the lens moving mechanism drive lens device, and laser beam forms bigger hot spot at far-end.
The present invention proposes a kind of device of on mobile communication terminal, realizing adjusting mobile phone laser pen focal length, it is by installing a focus control additional on the laser pen that carries at the mobile communication terminal mobile phone, during laser pen work, software on the user can Activate Phone by button, thereby drive this focus control work, and then adjusted the position of lens devices, promptly adjust the focal length of laser beam, the final size that realizes adjusting laser beam spot.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
