Abstract

Abstract A system for managing the number of image forming operations of an image forming apparatus is provided, wherein when the accumulated number of copies for a user exceeds a predetermined copying number to be allowed for the user, the copying operation is forced to continue up to the number of copies specified by the user at that time. However, when this condition is detected, an instruction for inhibiting the next copying operation by that user is delivered to a main unit of the image forming apparatus. The excess number of copies over the predetermined number is designated as the initial setting number in an accumulator for calculating an accumulated number of copies after resetting by a renewal arrangement.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 256 words
A system for managing the number of image forming operations of an image forming apparatus comprising: a code input means for inputting a user code; a sheet counter for counting a number of sheets processed by a main unit of said image forming apparatus; an accumulating means for calculating an accumulated number of sheets for each user from data in said user code supplied from said code input means and a count number counted by said sheet counter; a limit setting means for setting a predetermined number of sheets assigned to said user; a limit memory means for recording said predetermined number of sheets said user set by said limit setting means; a comparing means for comparing between said predetermined number of sheets recorded in said limit memory means and said accumulated number of sheets calculated by said accumulating means; and a controlling means for, upon judging from said comparing at said comparing means that said accumulated number of sheets of said user exceeds said predetermined number of sheets, forcing image forming operation of said apparatus to continue up to a specified number of sheets desired at the time by said user and means for delivering an instruction to said main unit of said apparatus for inhibiting image forming operation of said apparatus by said user from the next time and designating an excess number of sheets over said predetermined number of sheets as an initial setting number of said accumulating means for calculation of an accumulated number of sheets after resetting by a renewal arrangement.
Claim 2
Independent Claim 256 words
A system for managing the number of image forming operations of an image forming apparatus comprising: a code input means for inputting a user code; a sheet counter for counting a number of sheets processed by a main unit of said image forming apparatus; an accumulating means for calculating an accumulated number of sheets for each user from data in said user code supplied from said code input means and a count number counted by said sheet counter; a limit setting means for setting a predetermined number of sheets assigned to said user; a limit memory means for recording said predetermined number of sheets said user set by said limit setting means; a comparing means for comparing between said predetermined number of sheets recorded in said limit memory means and said accumulated number of sheets calculated by said accumulating means; and a controlling means for, upon judging from said comparing at said comparing means that said accumulated number of sheets of said user exceeds said predetermined number of sheets, forcing image forming operation of said apparatus to continue up to a specified number of sheets desired at the time by said user and means for delivering an instruction to said main unit of said apparatus for inhibiting image forming operation of said apparatus by said user from the next time and designating an excess number of sheets over said predetermined number of sheets as an initial setting number of said accumulating means for calculation of an accumulated number of sheets after resetting by a renewal arrangement.
Claim 3
Independent Claim 260 words
A system for managing the number of image forming operations of an image forming apparatus comprising: a code input means for inputting a user code; a sheet counter for counting a number of sheets processed by a main unit of said image forming apparatus; an accumulating means for calculating an accumulated number of sheets for each user from data in said user code supplied from said code input means and a count number counted by said sheet counter; a limit setting means for setting a predetermined number of sheets assigned to said user; a limit memory means for recording said predetermined number of sheets said user set by said limit setting means; a comparing means for comparing between said predetermined number of sheets recorded in said limit memory means and said accumulated number of sheets calculated by said accumulating means; and a controlling means for, upon judging from said comparing at said comparing means that said accumulated number of sheets of said user exceeds said predetermined number of sheets, forcing said image forming operation of said apparatus to continue up to a specified number of sheets desired at the time by said user and means for delivering an instruction to said main unit of said apparatus for inhibiting image forming operation of said apparatus by said user from the next time and making said number of sheets assigned to said user to be reduced by the number of excess of sheets over said predetermined number of sheets when a renewal arrangement for the image forming of said apparatus is engaged.
Claim 4
Independent Claim 260 words
A system for managing the number of image forming operations of an image forming apparatus comprising: a code input means for inputting a user code; a sheet counter for counting a number of sheets processed by a main unit of said image forming apparatus; an accumulating means for calculating an accumulated number of sheets for each user from data in said user code supplied from said code input means and a count number counted by said sheet counter; a limit setting means for setting a predetermined number of sheets assigned to said user; a limit memory means for recording said predetermined number of sheets said user set by said limit setting means; a comparing means for comparing between said predetermined number of sheets recorded in said limit memory means and said accumulated number of sheets calculated by said accumulating means; and a controlling means for, upon judging from said comparing at said comparing means that said accumulated number of sheets of said user exceeds said predetermined number of sheets, forcing said image forming operation of said apparatus to continue up to a specified number of sheets desired at the time by said user and means for delivering an instruction to said main unit of said apparatus for inhibiting image forming operation of said apparatus by said user from the next time and making said number of sheets assigned to said user to be reduced by the number of excess of sheets over said predetermined number of sheets when a renewal arrangement for the image forming of said apparatus is engaged.
Claim 5
Dependent Claim 46 words
A system for managing the number of image forming operations of an image forming apparatus according to claim 1, wherein: said controlling means is adapted for giving a warning sign when said accumulated number of sheets exceeds said predetermined number of sheets assigned to said user.
Claim 6
Dependent Claim 46 words
A system for managing the number of image forming operations of an image forming apparatus according to claim 2, wherein: said controlling means is adapted for giving a warning sign when said accumulated number of sheets exceeds said predetermined number of sheets assigned to said user.
