Abstract
Abstract A copy information output device for a copier for managing a number of modes by use of a RAM (random access memory). A paper sheet on which all the items and all the modes are printed is copied in a given test mode. Modes other than those currently set are smeared out by solid images so that only the current modes may be perceived by eyesight. Alternatively, modes other than current ones may be erased, and the current modes are transferred to a paper to facilitate confirmation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
151 words
A copy information output device for a copier, which includes a photoconductive element, using a chart sheet which is treatable as a recording paper sheet and printed with data and items associated with operation modes and information applicable to said copier, said device comprising: memory means for storing said modes and information; data inputting means for setting said modes and information; and charge erasing means for erasing a charge in any position on said photoconductive element based on said data associated with said modes and information which are stored in said memory means; said charge erasing means erasing said charge in those positions which are coincident with said modes and information which are stored in said memory means while leaving said charge in the other positions which are not coincident with said modes and information, whereby solid images are produced on said photoconductive element and, then, transferred to said chart sheet.
Claim 2
Dependent Claim
151 words
A copy information output device for a copier, which includes a photoconductive element, using a chart sheet which is treatable as a recording paper sheet and printed with data and items associated with operation modes and information applicable to said copier, said device comprising: memory means for storing said modes and information; data inputting means for setting said modes and information; and charge erasing means for erasing a charge in any position on said photoconductive element based on said data associated with said modes and information which are stored in said memory means; said charge erasing means erasing said charge in those positions which are coincident with said modes and information which are stored in said memory means while leaving said charge in the other positions which are not coincident with said modes and information, whereby solid images are produced on said photoconductive element and, then, transferred to said chart sheet.
Claim 3
Dependent Claim
26 words
A copy information output device as claimed in claim 1, wherein at least two kinds of operation modes are selectively set for each of said items.
Claim 4
Dependent Claim
18 words
A copy information output device as claimed in claim 1, wherein said memory means comprises a nonvolatile RAM.
Claim 5
Dependent Claim
142 words
A copy information output device for a copier, which includes a photoconductive element, using a chart sheet which is treatable as a recording paper sheet and printed with data and items associated with operation modes and information applicable to said copier, said device comprising: memory means for storing said modes and information; data inputting means for setting said modes and information; and charge erasing means for erasing a charge in any position on said photoconductive element based on said data associated with said modes and information which are stored in said memory means; said charge erasing means erasing said charge in, in a latent image which is associated with said chart sheet, those portions which do not coincide with said modes and information, the other portions of said latent image which are not erased being developed and transferred to a paper sheet.
Claim 6
Dependent Claim
142 words

Claim 7
Dependent Claim
26 words
A copy information output device as claimed in claim 4, wherein at least two kinds of operation modes are selectively set for each of said items.
Claim 8
Dependent Claim
18 words
A copy information output device as claimed in claim 4, wherein said memory means comprises a nonvolatile RAM.
