IPC: F02D45/00
Filed: 2000-04-24
Abstract: PROBLEM TO BE SOLVED: To provide communications equipment which can manage slave stations constituted of parts, having similar functions as same parts and whose cost can be reduced. SOLUTION: Drivers IC 11 to 14, constituting the slave stations, are connected to an engine control unit 10 being a master station in series.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device with short latency time, capable of monitoring change of status of a paper discharge tray or a paper feed tray even in a pause mode and of quickly recovering from the pause mode and resuming a job when a paper sheet is removed. SOLUTION: It is determined whether +5VE has changed into the pause mode by monitoring the status of the +5VE (Step 401).

If the discharge tray is not in the home position, the discharge tray is raised to the home position (Step 406).  If the discharge tray is determined to be in the home position by checking on Step 405, ascent of the discharge tray is stopped (Step 407), and the +24VE is switched off after a predetermined time lapse (Step 408), and then the mode changed into a normal pause mode.
