Abstract

Abstract A digital image forming apparatus has an operation device for successively entering copying conditions with respect to at least first and second documents which are successively set on a reading device and including a display part for displaying the copying conditions entered with respect to one document at one time, where the copying conditions for the second document are entered after the first document is read by the reading device and after a writing device starts to write the first document simultaneously as when the reading device starts to read the second document, and a control device for controlling operation timings of the reading device, a memory device, the writing device and the operation device so that the writing device starts to write the second document only after the writing of the first document is completed. The control device includes a part for controlling the operation device to automatically change the copying conditions displayed on the display part between the copying conditions for the first document and the copying conditions for the second document at an arbitrary time.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 255 words
A digital image forming apparatus comprising: reading means for optically reading a document which is set thereon and for outputting an image information of the document; memory means for storing the image information from said reading means, said memory means having a memory capacity for storing image information amounting to more than one document; writing means for writing the stored image information from said memory means onto a sheet of paper so as to form a copy print of the document read on said reading means; operation means for successively entering copying conditions with respect to at least first and second documents which are successively set on said reading means, said operation means including display means for displaying the copying conditions entered with respect to one document at one time, the copying conditions for the second document being entered after the first document is read by said reading means and after said writing means starts to write the first document simultaneously as when said reading means starts to read the second document; and control means for controlling operation timings of said reading means, said memory means, said writing means and said operation means so that said writing means starts to write the second document only after the writing of the first document is completed, said control means including means for controlling said operation means to automatically change the copying conditions displayed on said display means between the copying conditions for the first document and the copying conditions for the second document at an arbitrary time.
Claim 2
Dependent Claim 255 words
A digital image forming apparatus comprising: reading means for optically reading a document which is set thereon and for outputting an image information of the document; memory means for storing the image information from said reading means, said memory means having a memory capacity for storing image information amounting to more than one document; writing means for writing the stored image information from said memory means onto a sheet of paper so as to form a copy print of the document read on said reading means; operation means for successively entering copying conditions with respect to at least first and second documents which are successively set on said reading means, said operation means including display means for displaying the copying conditions entered with respect to one document at one time, the copying conditions for the second document being entered after the first document is read by said reading means and after said writing means starts to write the first document simultaneously as when said reading means starts to read the second document; and control means for controlling operation timings of said reading means, said memory means, said writing means and said operation means so that said writing means starts to write the second document only after the writing of the first document is completed, said control means including means for controlling said operation means to automatically change the copying conditions displayed on said display means between the copying conditions for the first document and the copying conditions for the second document at an arbitrary time.
Claim 3
Dependent Claim 59 words
A digital image forming apparatus as claimed in claim 1 in which said control means includes means for controlling said operation means to automatically change the copying conditions displayed on said display means from the copying conditions for the first document to the copying conditions for the second document after said writing means starts to write the first document.
Claim 4
Dependent Claim 48 words
A digital image forming apparatus as claimed in claim 2 in which said display means includes indication means for indicating whether the copying conditions displayed on said display means relates to a document being read by said reading means or a document being written by said writing means.
Claim 5
Dependent Claim 48 words
A digital image forming apparatus as claimed in claim 2 in which said control means includes means for keeping a count of a number of documents read by said reading means, and said display means includes indication means for indicating said count of the number of document read.
Claim 6
Dependent Claim 60 words
A digital image forming apparatus as claimed in claim 2 in which said control means includes means for controlling said operation means to automatically change the copying conditions displayed on said display means from the copying conditions for the second document to the copying conditions for the first document after said reading means completes the reading of the second document.
Claim 7
Dependent Claim 48 words
A digital image forming apparatus as claimed in claim 5 in which said display means includes indication means for indicating whether the copying conditions displayed on said display means relates to a document being read by said reading means or a document being written by said writing means.
Claim 8
Dependent Claim 48 words
A digital image forming apparatus as claimed in claim 5 in which said control means includes means for keeping a count of a number of documents read by said reading means, and said display means includes indication means for indicating said count of the number of document read.
Claim 9
Dependent Claim 59 words
A digital image forming appartus as claimed in claim 2 in which said control means includes means for controlling said operation means to automatically change the copying conditions displayed on said display means from the copying conditions for the second document to the copying conditions for the first document after the copying conditions are entered for the second document.
Claim 10
Dependent Claim 48 words
A digital image forming apparatus as claimed in claim 8 in which said display means includes indication means for indicating whether the copying conditions displayed on said display means relates to a document being read by said reading means or a document being written by said writing means.
Claim 11
Dependent Claim 48 words
A digital image forming apparatus as claimed in claim 8 in which said control means includes means for keeping a count of a number of documents read by said reading means, and said display means includes indication means for indicating said count of the number of document read.
