ABSTRACT:

This application is based on an application No. 11-173924 filed in Japan, the content of which is incorporated hereinto by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to image forming apparatuses.
2. Description of Related Art
In an image forming apparatus such as a digital copying machine, a series of document data read by a reader is stored as jobs in a memory, is then read out from the memory, and is copied on a copy paper. Once the job is read out, and document data which is its contents is copied on a copy paper(this is referred to as “the job is executed”), the job stored in the memory cannot be read out again and copied on the copy paper. When it is desired to copy the contents of the job which has been executed in the past, the document data must be read again and stored as the job.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an image forming apparatus capable of reading out, even after a job is executed, a job which is stored in storage means again, to copy image data of the job on a copy paper sheet.
The present invention is directed to an image forming apparatus comprising a reading mechanism for reading image data on a document; a memory for storing a series of image data read by the reading mechanism as jobs; a mode switching key for switching a normal mode and a re-output mode; and a start signal entry key, for reading out predetermined image data which has already been stored in the memory and copying the predetermined image data read out on a copy paper without reading the image data by the reading mechanism in response to entry of a start signal by the start signal entry key in a state where the re-output mode is set by the mode switching key.
According to the present invention, an image forming apparatus capable of re-outputting the image data stored in the storage means is obtained even after the job is executed.
