Abstract
A network type exposure unit connected via a communication network to other exposure units or to an information processor determines whether or not exposure work information of the instructed kind of exposure work is in the storage thereof. When the instructed exposure work information is determined to be non-existent, the unit inquires of the other exposure units or a host equipment whether or not there is therein the exposure work information, and decides executability of the exposure work requested to be started from the result thereof. The exposure work information can be transferred between arbitrary units, thereby alleviating complexity of maintenance and management of the exposure work information.
