Copying device provided with countermeasure for power failure

Abstract

Abstract PURPOSE:To continue the processing by the subsequent power source-on, if the remaining processing exists, even if the power source is turned off suddenly, by updating and storing the present processing progress data in a nonvolatile RAM, and continuing the processing which is left at the time of the power source-off, based on the processing progress data which is stored in the nonvolatile RAM. CONSTITUTION:In a nonvolatile RAM 32, a data of the present processing contents is also stored, and updated successively. As for the data of said processing contents, there are a color balance data for showing that a color balance mechanism in a lens system 4d of an exposure part A is a diaphragm mechanism, a diaphragm data, a data for the present carrying position of a sheet in a feeding part B, and if paper jam is generated, a data for a fact of its paper jam and a paper jam position, a processing position data of the sheet in a process processing part C, etc. On the other hand, when the power source is turned on, in case the data of said processing contents is stored, its processing contents are continued, and also, as for the paper jam, etc., display and warning are generated.
