Abstract
Abstract A specific cassette selection apparatus for use with a copying machine having a plurality of removable paper feeding cassettes. The apparatus includes an identification device, a specific copying mode selection device, and a paper feeding cassette selection device. The cassette selection device responds to paper-size identification signals from the identification device and a copying mode selection signal from the mode selection device to select a cassette for use in a selected copying mode. When either a two-sided copying mode or a continuous copying mode is selected, the paper feeding cassette selection device selects a specific paper feeding cassette containing copying paper of only a specific paper size associated with the two-sided copying and/or the continuous copying modes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
A specific cassette selection apparatus for a copying machine capable of forming a copied image of an original document on copying paper fed from a paper feeding cassette selected from a plurality of paper feeding cassettes removably mounted on the body of the copying machine, said specific cassette selection apparatus comprising: identification means for identifying the size of paper contained in each of said paper feeding cassettes and providing paper-size identification signals indicative thereof; specific copying mode selection means for enabling selection of a copying mode selected from a plurality of copying modes, including an automatic two-sided copying mode, and for providing a copying mode selection signal indicative of the selected copying mode; and paper feeding cassette selection means, responsive to the paper-size identification signals and the copying mode selection signal, for selecting from among the plurality of paper feeding cassettes on the copying machine a cassette containing copying paper for use in copying in the selected copying mode, said paper feeding cassette selection means selecting only a specific paper feeding cassette containing copying paper of only a specific paper size for use in copying in said automatic two-sided copying mode.
Claim 2
Dependent Claim
191 words
A specific cassette selection apparatus for a copying machine capable of forming a copied image of an original document on copying paper fed from a paper feeding cassette selected from a plurality of paper feeding cassettes removably mounted on the body of the copying machine, said specific cassette selection apparatus comprising: identification means for identifying the size of paper contained in each of said paper feeding cassettes and providing paper-size identification signals indicative thereof; specific copying mode selection means for enabling selection of a copying mode selected from a plurality of copying modes, including an automatic two-sided copying mode, and for providing a copying mode selection signal indicative of the selected copying mode; and paper feeding cassette selection means, responsive to the paper-size identification signals and the copying mode selection signal, for selecting from among the plurality of paper feeding cassettes on the copying machine a cassette containing copying paper for use in copying in the selected copying mode, said paper feeding cassette selection means selecting only a specific paper feeding cassette containing copying paper of only a specific paper size for use in copying in said automatic two-sided copying mode.
Claim 3
Dependent Claim
66 words
A specific cassette selection apparatus as set forth in claim 1, wherein said plurality of modes further include a continuous copying mode, said specific copying mode selection means enabling selection of said continuous copying mode and said paper feeding cassette selection means selecting only a specific paper feeding cassette containing paper of only a specific paper size for use in copying in said continuous copying mode.
Claim 4
Dependent Claim
75 words
A specific cassette selection apparatus as set forth in claim 2, wherein said paper feeding cassette selection means further comprises means for providing a display signal indicative of a specific paper feeding cassette whenever one of said two-sided copying or continuous copying modes is selected by said specific copying mode selection means and the specific paper feeding cassette associated with the selected two-sided copying or continuous copying mode is not mounted to the copying machine.
Claim 5
Dependent Claim
46 words
A specific cassette selection apparatus as set forth in claim 1, wherein said paper feeding cassette selection means further comprises means for providing a display signal indicative of the specific paper feeding cassette whenever said specific paper feeding cassette is not mounted to the copying machine.
Claim 6
Dependent Claim
189 words
A specific cassette selection apparatus for a copying machine capable of forming a copied image of an original document on copying paper fed from a paper feeding cassette selected from a plurality of paper feeding cassettes removably mounted on the body of the copying machine, said specific cassette selection apparatus comprising: identification means for identifying the size of paper contained in each of said paper feeding cassettes and providing paper-size identification signals indicative thereof; specific copying mode selection means for enabling selection of a copying mode selected from a plurality of copying modes, including a continuous copying mode, and for providing a copying mode selection signal indicative of the selected copying mode; and paper feeding cassette selection means, responsive to the paper-size identification signals and the copying mode selection signal, for selecting from among the plurality of paper feeding cassettes on the copying machine a cassette containing copying paper for use in copying in the selected copying mode, said paper feeding cassette selection means selecting only a specific paper feeding cassette containing copying paper of only a specific paper size for use in copying in said continuous copying mode.
