Abnormality information is announced whenever it occurs or at a predetermined time according to a degree of abnormality, and information concerning the abnormality information announced is displayed on a part or full of the whole display picture screen concerning all the control processing. Further, a record of the abnormality information is stored and displayed and also information on a function along with usage quantity information of consumable goods are displayed in lists, thus notice of abnormality when it occurs and search for its cause are accurately conducted. Still further the system accurately predicts a date for replacement or supply of the consumable goods on the basis of usage quantity information, thus reducing using-up of the con sumable goods.</p> |
