<P>PROBLEM TO BE SOLVED: To provide an automatic feeding device that can easily and appropriately operate a work of loading a loading base under a dark light with a plurality of only planographic printing plates in a stacked and bundled state. <P>SOLUTION: The housing of an automatic feeding device for a planographic printing plate 111 blocks light to prevent a photosensitive layer of the planographic printing plate 111 inside from being exposed to light. A light-shielding door 142 having a structure to prevent light from intruding into the inside when the door is closed is attached so as to be capable of being opened and closed to a part of the housing. A loading base 144 is placed inside the housing and a plurality of planographic printing plates 111 in a predetermined number stacked and bundled by bringing a back face of one planographic printing plate 111 into direct contact with the surface of the other planographic printing plate 111 are configured to be loaded on the loading base 144 in the state that the light shielding door 142 is opened. The work of loading the base with a bundle of planographic printing plates 111 is made easy by irradiating the loading base with light having no wavelength at which the photosensitive layer of the printing plate 111 is sensitive. <P>COPYRIGHT: (C)2007,JPO&INPIT |
