Abstract

PURPOSE: To transfer always date vividly with a simple constitution, by using a liquid crystal panel to shield the light as required.
CONSTITUTION: When a voltage is applied to electrode 6 of liquid crystal panel 5 using the FE type twist nematic liquid crystal and so on, liquid crystal molecules are arranged to stop light rotation, and the image light from lens 1 is shielded by electrode 6. Consequently, the optical image of data plate 3, which is in the position corresponding to electrode 6, dependent upon transfer lamp 4 is focused onto film 2, and the object light is not focused onto this part. When no voltage is applied to electrode 6 in case of no transfer, the optical image without the lost part, which is not shielded by electrode 6, dependent upon the object light is focused onto film 2. consequently, data can be always transferred vividly by the simple light shielding constitution without requiring movement.
