By using a precision dicing-machine, we obtained the unique structure of PLZT optical shutter element having a 3-dimensional electrode and achieved low driving voltage of shutters. As a result, we have created a prototype PLZT optical shutter array with resolution of 400dpi, print width up to 300mm and a few micro second switching time, and its printing has been succeeded.
It is expected that the PLZT optical shutter array will be a telling device for development of a high speed electophotographic printer and a full-color printer using silver halide photography and so on.
