Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
An image forming apparatus the apparatus comprising: means for mounting peripheral devices to the apparatus; a memory for storing copying condition data sets sequentially wherein said copying condition data sets include the size of sheets, or size of original, documents, numbers of copies from an original document and number of original documents; means operatively connected to the memory, for determining whether each data set of said sequential data sets in said memory are of successive copying events or not and for counting said successive copying events in a predetermined period of time; means operatively connected to said memory, for assessing a necessity of equipping an additional peripheral device based on a criteria involved in said copy condition data set and said successive copying events; and means operatively connected to said memory for informing an operator whether said additional peripheral device is necessary or not.
Claim 2
Dependent Claim
144 words
An image forming apparatus the apparatus comprising: means for mounting peripheral devices to the apparatus; a memory for storing copying condition data sets sequentially wherein said copying condition data sets include the size of sheets, or size of original, documents, numbers of copies from an original document and number of original documents; means operatively connected to the memory, for determining whether each data set of said sequential data sets in said memory are of successive copying events or not and for counting said successive copying events in a predetermined period of time; means operatively connected to said memory, for assessing a necessity of equipping an additional peripheral device based on a criteria involved in said copy condition data set and said successive copying events; and means operatively connected to said memory for informing an operator whether said additional peripheral device is necessary or not.
Claim 3
Dependent Claim
130 words
An image forming apparatus with a set of peripheral devices, incapable of equipping an additional peripheral device, the apparatus comprising: a memory for storing copying condition data sets sequentially, wherein said copying data set including size of sheets or size of original document, numbers of copies from an original document, and number of original documents; means for determining whether each data set of said sequential data in said memory is of a successive copying event or not, and to count said successive copying events in a predetermined period of time; means for assessing the necessity of equipping an additional peripheral device based on the criteria involved in said copying condition data and said successive copying events; and means for informing an operator whether said peripheral device is necessary or not.
Claim 4
Dependent Claim
130 words
An image forming apparatus with a set of peripheral devices, incapable of equipping an additional peripheral device, the apparatus comprising: a memory for storing copying condition data sets sequentially, wherein said copying data set including size of sheets or size of original document, numbers of copies from an original document, and number of original documents; means for determining whether each data set of said sequential data in said memory is of a successive copying event or not, and to count said successive copying events in a predetermined period of time; means for assessing the necessity of equipping an additional peripheral device based on the criteria involved in said copying condition data and said successive copying events; and means for informing an operator whether said peripheral device is necessary or not.
Claim 5
Dependent Claim
130 words
In an image forming apparatus that includes means for allowing mounting of peripheral devices, and a memory for storing copying condition data sets sequentially wherein said copying condition data sets include the size of sheets or size of original documents, number of copies from an original document and number of original documents; the method comprising the steps of: (a) determining whether each data set of said sequential data sets in said memory is of a successive copying event or not; (b) counting said successive copying events occurring in a predetermined time; (c) assessing a necessity of equipping an additional peripheral device based on a criteria-involved in said copying condition data set and said successive copying events; and (d) informing an operator whether said additional peripheral device is necessary or not.
Claim 6
Dependent Claim
130 words
In an image forming apparatus that includes means for allowing mounting of peripheral devices, and a memory for storing copying condition data sets sequentially wherein said copying condition data sets include the size of sheets or size of original documents, number of copies from an original document and number of original documents; the method comprising the steps of: (a) determining whether each data set of said sequential data sets in said memory is of a successive copying event or not; (b) counting said successive copying events occurring in a predetermined time; (c) assessing a necessity of equipping an additional peripheral device based on a criteria-involved in said copying condition data set and said successive copying events; and (d) informing an operator whether said additional peripheral device is necessary or not.
Claim 7
Dependent Claim
24 words
The apparatus of claim 1 or claim 2 wherein said peripheral device is an automatic document feeder, paper cassette of different capacity or sorter.
Claim 8
Dependent Claim
28 words
The apparatus of claim 1 or claim 2 wherein said data sets further comprises date, cassette capacity, open/close state of an original cover, and state of the sorter.
Claim 9
Dependent Claim
80 words
The apparatus of claim 1 or claim 2 wherein said data sets are automatically fed from operation display, document size and direction detector, original cover state detector, paper empty detector, and sorter state detector, and are automatically stored in a memory region in RAM sequentially: wherein said assessing program for a desired peripheral device in ROM is loaded and automatically run in a CPU by the operator's operation; so as to determine; whether said peripheral device is necessary or not.
