Thin film circuit is connected.
Wherein, ray cast device includes rotating base, runing rest and projection lamp, rotating base and projected keyboard main body
It is connected, rotating base upper shaft is connected with runing rest, and projection lamp is respectively arranged on two axle sides of runing rest.
Wherein, ray tracing instrument assembly includes securing bracket and ray tracing instrument, and ray tracing instrument is installed on fastening
Above frame, the front end of ray tracing instrument is provided with light sensor, within light sensor induction range is 75 ° of ray tracing instrument
Orthogonal angles, within actual induction distance is for 35cm.
Wherein, light sensor mainly senses ray cast device produced light pair when projected keyboard main body projects
Penetrate, the optical signal of retroreflecting and scattered reflection, and carry out corresponding transformational analysis for the optical signal collecting.
The utility model has the advantages that：
1. the utility model passes through Optimal Structure Designing, using projection ray's induction keyboard operation, when operator's finger is pressed
When pressing the projected keyboard image in projected keyboard main body, the throwing that ray cast device sends is judged by ray tracing instrument block analysis
The conversion record button result of shadow light, senses, with the pliable pressure in projected keyboard main body, the data that screen is collected simultaneously
Result carries out coupling and compares, and carries out key-press input.
2. the shadow through appropriate design projects keyboard, senses ray cast device in projected keyboard master by light sensor
During body projection produced light to penetrating, the converting optical signals of retroreflecting and scattered reflection, judge the result of institute's typewriting input,
And input comparison correction, the standard of bimodulus two-way raising projection input are carried out by the piezoelectric signal that pliable pressure senses screen simultaneously
Really property.
