PURPOSE: To perform the stock control of consumables and to reduce the downtime caused by the shortage of the stock of the consumables in an image forming device by providing a delivery data control part, a stock data control part, a stock shortage prediction part and a delivery instruction part. CONSTITUTION: When the setting of a delivery condition is required from the delivery data control device 3, a host computer 4 transmits the stock data of a corresponding copying machine 1 from the data base for controlling a copying machine of an external recorder The device 3 allows a paper control information screen 81 to perform display, so that the number of used sheets and present stock amounts in the corresponding copying machine 1 are displayed in a used sheet number blank 82 and a stock amount column 83. The stock shortage time is displayed in a delivery date prediction column, and when an emergent ordering requiring report is given from a copying machine control device 2, the date at that time is displayed in an ordering requirement column 86. Thus, the stock control classified by paper sizes in each copying machine 1 is accurately performed in the host computer 4 and the efficient delivery instruction can be achieved. |
