摘要： A compact or tabletop electrostatic book copier having at the top thereof an exposure station on which a book is laid with a mirror and lens optical system for projecting an image of the book page to a more or less vertical exposing station. Paper is fed from a paper safe at the bottom of the machine through a charging unit substantially horizontally, and then substantially vertically up to the exposing station where the paper is exposed. From the top of the exposing station the paper is fed face down in a downwardly diagonal direction over a developing station, and along an inverting reentrant path to a delivery station immediately above the developing station where the copy is delivered face up.
