Abstract:
1. A plate supply and discharge device which supplies a plate to a drawing unit, receives a printing plate having an image drawn thereon from the drawing unit, and delivers the printing plate outside, the plate supply and discharge device comprising: a plate supply table which includes: a first atmospheric pressure flotation unit that vertically directs a jet of air at the plate and allows the plate to float at atmospheric pressure; a first airflow transfer unit that obliquely directs a jet of air at the plate and transfers the plate at atmospheric pressure; and a plurality of plate positioning guides disposed at different positions depending on the size of the plate so as to correspond to one side among four sides of the plate; a plate discharge table which includes: a second atmospheric pressure flotation unit that vertically directs a jet of air at the printing plate and allows the printing plate to float at atmospheric pressure; a second airflow transfer unit that obliquely directs a jet of air at the printing plate and transfers the printing plate at atmospheric pressure; and a plurality of printing plate positioning guides disposed at different positions depending on the size of the printing plate so as to correspond to one side among four sides of the printing plate, wherein the plate in a state of being allowed to float at atmospheric pressure is moved above the plate supply table and supplied to the drawing unit, and the printing plate in a state of being allowed to float at atmospheric pressure is moved above the plate discharge table and delivered outside.
