Above-mentioned minitype projection machine 4, camera module 5 and touch-control sensing mechanism 6 then know clearly as described below for being mounted on the principal character structure of the disclosed keyboard of present embodiment:

One embodiment (as shown in Figure 4) of relevant this minitype projection machine 4, it is the shadow casting technique that adopts built-in laser light source, it comprises: one is used to handle the image process unit 41 of digitized video; One is electrically connected with image process unit 41 in order to storing the image internal memory 42 from the image of image process unit 41, and this image internal memory 42 is sent to image process unit 41 according to instruction and with the image that stores; One image-generating unit 43; One glasses lens drive unit 44; One laser light source 45, it is subjected to image process unit 41 controls in order to the emission laser light; One projection eyeglass 46, it is subjected to these glasses lens drive unit 44 controls and will goes out from the light scattering of laser light source 45; One bus 47 is in order to be electrically connected this image process unit 41, image-generating unit 43 and glasses lens drive unit 44, to reach a microprocessor (Microprocessor) 48; This microprocessor 48 is electrically connected these buses 47 and in order to control the operation of this image process unit 41, image-generating unit 43 and glasses lens drive unit 44.Minitype projection machine 4 of the present utility model is with the imaging of laser scan mode, its imaging picture need not focus and light loss few, and have preferable image sharpness and chroma-luminance.

This microprocessor 48 is by this

keyboard body

10 and 70 controls of this main frame, the user is when the needs projection, can operate this main frame 70 starts to make this microprocessor 48, even and these microprocessor 48 these image process units 41 take out the image of desiring projection by this image internal memory 42, this image process unit 41 also makes this image-generating unit 43 beginning imagings, and make this laser light source 45 emission laser light, and making this glasses lens drive unit 44 start this projection eyeglass 46, the laser light that last image promptly sends by this projection eyeglass 46 is incident upon one and penetrates in the projection screen 95 of wall (as shown in Figure 3).And this minitype projection machine 4 is pivotable means, so the user can adjust projection angle easily to reach best drop shadow effect.

Another embodiment of this minitype projection machine 4 is to adopt the projection digital light of being researched and developed in the imaging technique that is used for minitype projection machine and rear-projection TV by Texas Instruments to handle (Digital Light Processing (DLP)) technology.In DLP projector, image is to be produced by Digital Micromirror Device (DigitalMicromirror Device (DMD)), DMD is provided with a matrix of being made up of micromirror (catoptron of accurate miniature) on semi-conductor chip, a pixel in each micromirror control projected picture.The quantity of micromirror conforms to the resolution of projected picture, and specification 800 * 600,1024 * 768,1280 * 720 and 1920 * 1080 (HDTVs) are the sizes of some common DMD.These micromirror can change angle rapidly under the control of digital drive signals, in case receive corresponding signal, micromirror will tilt 10 °, thereby the reflection of incident light direction is changed.The micromirror that is in projection state is illustrated as " opening ", and with digital signal tilt+10 °; If micromirror is in non-projection state, then is illustrated as " pass ", and tilts-10 °.Meanwhile, " open " incident light that is reflected away under the state by projecting lens with image projecting to display screen; And the incident light that is reflected on the micromirror under " pass " state is absorbed by light absorber.

Projector and its advantage of rear-projection TV of producing with the DLP technology are: the image smoothing smoothness, outstanding color depth and contrast, the shortcoming of no traditional LC D technology itself, can access seamless image quality, the DLP rear-projection TV is littler, thinner, lighter than cathode-ray tube (CRT) (Cathode Ray Tube (CRT)) TV, light source is replaceable, so potential life-span is longer than CRT and plasma display panel, and light source is changed more easier than liquid crystal (Liquid CrystalDisplay (LCD)) projector.

An embodiment again of this minitype projection machine 4, relevant projection reflection type liquid crystal technique (Liquid Crystal OnSilicone (LCOS)) is the combination technology of LCD and DLP projector, and the LCOS panel is to be circuit substrate and reflection horizon with the CMOS chip, itself and DLP projector are both the employing reflective structure, its light source can not penetrate the LCOS panel, three primary colors light beam after the partition, meeting is through a polarization spectroscope (Polarization Beam Splitter (PBS)) before entering the LCOS panel, and LCoS projector utilizes the LCOS panel, come modulation to come out and desire to project to the light signal of screen by light emitted, because the light that light source sends can't penetrate the LCOS panel, belong to reflective imaging, and it develops to picture by projection lens to be projected to the screen place.

One embodiment (as shown in Figure 5) of relevant this camera module 5, this camera module 5 comprises: an optical system 51, in order to take pictures, one image sensor 52, the image that is photographed by optical system 51 in order to sensing, one analog-digital converter (analog to digital converter (ADC)) 53, become digital signal in order to the analog signal conversion that image sensor 52 is sensed image, one image-generating unit 56, in order to digital signal is formed image, one ROM (read-only memory) (Read-Only Memory (ROM)) 54, in order to store to start the essential software program of camera module 5, one work internal memory 55, the image data that photographs in order to temporary transient storage, one compression and decompression unit 57, in order to image is compressed or decompresses to be stored in the extraction-type memory device 59, use for other digitalized electron device, an and microprocessor (Microprocessor) 58, it is electrically connected this image sensor 52, analog-digital converter (ADC) 53, image-generating unit 56, ROM (read-only memory) (ROM) 54, work internal memory 55 and compression and decompression unit 57, control its shooting operation action in order to central authorities, wherein this microprocessor 58 can be sent to the display screen 30 of main frame 70 with show image with the image data that stores in the work internal memory 55 again.

This microprocessor 58 is by the control of this keyboard body 10 and this main frame 70, when the user photographs at needs, can operate this keyboard body 10 and this main frame 70 starts to make this microprocessor 58, and even these microprocessor 58 optical systems 51 are taken pictures (for example taking the object 90 among Fig. 2), this image sensor 52 is the image that photographs of sensing then, wherein 53 of this analog-digital converters become digital signal with this analog signal conversion that senses, this image-generating unit 56 then forms image with the digital signal demonstration, 55 temporary transient image datas that photograph that store of this work internal memory, the image data that stores in the internal memory 55 of will working again at last is sent to the display screen 30 of main frame 70 with show image.And this camera module 5 is pivotable means, so the user can adjust camera angle easily to reach best shooting effect.
