Abstract

Abstract Disclosed is a recording sheet feeding apparatus for feeding recording sheets singly to a copying machine, comprising a sheet storage cassette (B) for storing the recording sheets, a conveyance roller (1) for conveying the recording sheets from the sheet storage cassette (B) to a feeding roller (2), the feeding roller (2) for feeding the recording sheets conveyed from the sheet storage cassette (B) to the copying machine, a sheet separation roller (3), in contact with the feeding roller (2), for separating one of the recording sheets from other recording sheets so that the recording sheets are fed to the copying machine singly, and a rotation resister for resisting the rotation of the sheet separation roller (3) by frictional resistance of a resistant member in which the sheet separation roller (3) is further capable of rotating in an opposing direction to the feeding roller (2) by the resiliency of a spring (11) so that the other recording sheets separated by the sheet separation roller (3) are fed back towards the sheet storage cassette (B).

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 172 words
A recording sheet feeding apparatus for feeding a plurality of recording sheets singly to a copying apparatus, comprising; a sheet storage means for storing said recording sheets, a conveyance roller means for conveying said recording sheets from said sheet storage means to a feeding roller means, said feeding roller means for feeding said recording sheets conveyed from said sheet storage means to said copying apparatus, a sheet separation roller means, in contact with said feeding roller means, for separating one of said recording sheets from others of said recording sheets so that said recording sheets are fed to said copying apparatus singly, and a rotation resisting means for resisting the rotation of said sheet separation roller means by frictional resistance of a resistant member. wherein said sheet separation roller means is further capable of rotating in an opposing direction to said feeding roller means by the resiliency of a spring member so that said other recording sheets separated by said sheet separation roller means are fed back towards said sheet storage means.
Claim 2
Dependent Claim 172 words
A recording sheet feeding apparatus for feeding a plurality of recording sheets singly to a copying apparatus, comprising; a sheet storage means for storing said recording sheets, a conveyance roller means for conveying said recording sheets from said sheet storage means to a feeding roller means, said feeding roller means for feeding said recording sheets conveyed from said sheet storage means to said copying apparatus, a sheet separation roller means, in contact with said feeding roller means, for separating one of said recording sheets from others of said recording sheets so that said recording sheets are fed to said copying apparatus singly, and a rotation resisting means for resisting the rotation of said sheet separation roller means by frictional resistance of a resistant member. wherein said sheet separation roller means is further capable of rotating in an opposing direction to said feeding roller means by the resiliency of a spring member so that said other recording sheets separated by said sheet separation roller means are fed back towards said sheet storage means.
Claim 3
Dependent Claim 21 words
The apparatus claimed in claim 1, wherein said spring member is tensioned by the rotation of said sheet separation roller means.
Claim 4
Dependent Claim 40 words
The apparatus claimed in claim 2, wherein said sheet separation roller means further comprises a supporting shaft member for supporting a roller member thereon, and said spring member and said rotation resisting means are disposed on said supporting shaft member.
