Abstract
Abstract This apparatus forms multiplex images on an image receiving member and prevents any misregistration between the images on the image receiving member by making the distance between adjacent ones of image processing stations disposed along the direction of conveyance of the image receiving member integer times the distance over which the image receiving member is conveyed by one full rotation of rotative driving means.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
An image receiving member conveying device for a multiplex image forming apparatus in which a plurality of images are superposed on an image receiving member and made into a final image, said device comprising: rotative driving means for moving the image receiving member by rotation; a plurality of image processing stations disposed along the direction of movement of said image receiving member at which stations images can be formed on the image receiving member passing therethrough; and means for conveying the image receiving member through said image processing stations, the distance between adjacent ones of said image processing stations being integer times the amount by which the image receiving member is conveyed by one full rotation of said rotative driving means.
Claim 2
Dependent Claim
121 words
An image receiving member conveying device for a multiplex image forming apparatus in which a plurality of images are superposed on an image receiving member and made into a final image, said device comprising: rotative driving means for moving the image receiving member by rotation; a plurality of image processing stations disposed along the direction of movement of said image receiving member at which stations images can be formed on the image receiving member passing therethrough; and means for conveying the image receiving member through said image processing stations, the distance between adjacent ones of said image processing stations being integer times the amount by which the image receiving member is conveyed by one full rotation of said rotative driving means.
Claim 3
Dependent Claim
29 words
The device of claim 1, wherein said image receiving member is conveyed by an endlessly moving holding member and said rotative driving means drives said endlessly moving holding member.
Claim 4
Dependent Claim
18 words
The device of claim 1, wherein said rotative driving means rotates to directly convey the image receiving member.
Claim 5
Dependent Claim
16 words
The device of claim 1 or 2, wherein said image receiving member is a cut sheet.
Claim 6
Dependent Claim
17 words
The device of claim 1 or 2, wherein said image receiving member is a substantially continuous sheet.
Claim 7
Dependent Claim
36 words
The device of claim 1, wherein said rotative driving means includes a drive source and transmission means for transmitting driving motion to said rotative driving means, said transmission means including gears having an integer gear ratio.
Claim 8
Dependent Claim
135 words
An image receiving member conveying device for a multiplex image forming apparatus in which a plurality of images are superposed on an image receiving member and made into a final image, said device comprising: driving roller means for moving the image receiving member by rotation; a plurality of image processing stations disposed along the direction of movement of said image receiving member for forming toner images corresponding to the image receiving member being conveyed, the toner images being transferred to the image receiving member as it passes through said stations; and means for conveying the image receiving member through said image processing stations, the distance between adjacent ones of said image processing stations being integer times the amount by which the image receiving member is conveyed by one full rotation of said driving roller means.
Claim 9
Dependent Claim
135 words
An image receiving member conveying device for a multiplex image forming apparatus in which a plurality of images are superposed on an image receiving member and made into a final image, said device comprising: driving roller means for moving the image receiving member by rotation; a plurality of image processing stations disposed along the direction of movement of said image receiving member for forming toner images corresponding to the image receiving member being conveyed, the toner images being transferred to the image receiving member as it passes through said stations; and means for conveying the image receiving member through said image processing stations, the distance between adjacent ones of said image processing stations being integer times the amount by which the image receiving member is conveyed by one full rotation of said driving roller means.
Claim 10
Dependent Claim
21 words
The device of claim 7, wherein said image processing stations transfer toner images of different colors to the image receiving member.
Claim 11
Dependent Claim
29 words
The device of claim 7, wherein said image processing stations form yellow, magenta and cyan color toner images and form a full color image on the image receiving member.
Claim 12
Dependent Claim
36 words
The device of claim 7, wherein said driving roller means includes a drive source and transmission means for transmitting driving motion to said driving roller means, said transmission means including gears having an integer gear ratio.
