Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
A sheet discharging device for a digital image forming apparatus which forms an image in any one of at least two image input modes, comprising: a sheet inlet; at least two sheet outlets; means for forming respectively separate sheet transport paths to said at least two sheet outlets, at least one of said at least two transport paths including means for turning over a sheet passing therethrough; and selecting means for selecting one of said at least two transport paths as a transport path for a sheet from said inlet to be transported to said outlet, as a function of a selected one of said image input modes.
Claim 2
Dependent Claim
108 words
A sheet discharging device for a digital image forming apparatus which forms an image in any one of at least two image input modes, comprising: a sheet inlet; at least two sheet outlets; means for forming respectively separate sheet transport paths to said at least two sheet outlets, at least one of said at least two transport paths including means for turning over a sheet passing therethrough; and selecting means for selecting one of said at least two transport paths as a transport path for a sheet from said inlet to be transported to said outlet, as a function of a selected one of said image input modes.
Claim 3
Dependent Claim
41 words
A device as claimed in claim 1, wherein the at least two modes comprise a copier mode, a facsimile mode and a printer mode, in which said image forming equipment operates as a copier, a facsimile transceiver, and a printer, respectively.
Claim 4
Dependent Claim
25 words
A device as claimed in claim 1, wherein said outlets are each located at a particular discharge level matching a particular one of the modes.
Claim 5
Dependent Claim
28 words
A device as claimed in claim 1, wherein a finisher having an inlet communicating to any one of said outlets is operatively connected to said image forming equipment.
Claim 6
Dependent Claim
33 words
A device as claimed in claim 4, further comprising inhibiting means for inhibiting the sheet from being transported to the outlets other than said outlet to which said inlet of said finisher communicates.
Claim 7
Dependent Claim
30 words
A device as claimed in claim 1, further comprising reversing means for turning over, in particular one of the modes, the sheet being transported toward particular one of said outlets.
Claim 8
Dependent Claim
33 words
The sheet discharging device of claim 1 wherein the selecting means selects the at least one of the transport paths including means for turning over a sheet in a facsimile image input mode.
