摘要:
A sheet delivery device having a plurality of delivery trays, a printed sheet detector for detecting whether residual printed sheets are present in a delivery tray other than a selected delivery tray, a full storage detector for detecting a full storage state of the selected delivery tray, a sheet delivery unit for delivery sheets to the selected delivery tray and a control unit for controlling the sheet delivery unit. When the printed sheet detector detects residual printed sheets in the next delivery tray other than the selected delivery tray and when the destination of the printed sheet is changed from the selected delivery tray to the other delivery tray, the sheet delivery unit delivers printed sheets to the other delivery tray in a manner so that the printed sheets can be discriminated from the residual sheets.
摘要:
An interface control system overcomes deficiencies of by adopting a structure comprising host computers connected with peripheral devices, each host computer including a start-up status recognition unit and each peripheral device having a start-up status notification unit. The start-up status recognition unit receives information about start-up processing progress status of a peripheral device of interest, and peripheral device information including identification information about a parent device causing the peripheral device to perform start-up processing. The peripheral device information is transmitted to host computers by the start-up status notification unit of each peripheral device. Before a host computer causes a peripheral device to perform start-up processing, the start-up status recognition unit of the host recognizes the start-up status of the peripheral device in question on the basis of the received start-up processing status information and peripheral device information. Knowing the peripheral device start-up status allows the host computer to determine the necessity of starting up the peripheral device in question, whereby unnecessary start-up processing is averted and the efficiency of system operation is enhanced.
