Abstract

PURPOSE: To provide a compact typing method, by inserting a light emitting substance or a substance for selectively transmitting a light between 2 transparent plates, such as glass plates, and arranging transparent electrodes on one side and transparent or opaque electrodes on the other side.
CONSTITUTION: A typing apparatus consists of light source 1 and cruved surface mirror 2, the light emitted from source 1 and reflected with mirror 2 is made parallel to illuminate a selective light transmission unit in parallel. Glass plates 3a, 3b are used for sealing in selective light transmitter 3, such as liquid crystal, and 4a, 4b are transparent electrodes. Photosensitive plate 5 has been charged positively or negatively before entering an optical pattern forming unit. An operation control unit decides to which columns and ranks voltage is applied in order to form a letter or a mark on plate 5 in the pattern forming unit. As a result, the optical pattern of a letter or a mark selectively transmitted from source 1 via mirror 2 is formed as an electrostatic latent image on plate 5.
