Abstract
Abstract A paper loading apparatus for a printing device which includes paper advancing means for advancing a sheet of paper within the printing device, the paper loading apparatus comprising paper storing means for storing a plurality of individual sheets of paper, paper feeding means for feeding individual sheets of paper from said paper storing means along a paper feed path to said paper advancing means, and engaging means movable between an operative position for engaging said paper storing means so as to position the plurality of individual sheets of paper within said paper storing means for feeding by said paper feed means and an operative position, said paper loading apparatus being characterized by first and second cam surfaces (226, 228) on said paper storing means (10), and by cam follower means (176) associated with said engaging means (168, 170) for moving said engaging means between said operative and said inoperative positions when said cam follower means engages said first and second cam surfaces on said paper storing means, said cam follower means being operative to move said engaging means towards said inoperative position when said cam follower means engages said first cam surface upon insertion of said paper storing means within said printing device, and being operative to move said engaging means towards said operative position into engagement with said paper storing means when said cam follower means engages said second cam surface upon further insertion of said paper storing means within said printing device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
246 words
1 . A paper loading apparatus for a printing device which includes paper advancing means for advancing a sheet of paper within the printing device, the paper loading apparatus comprising paper storing means for storing a plurality of individual sheets of paper, paper feeding means for feeding individual sheets of paper from said paper storing means along a paper feed path to said paper advancing means, and engaging means movable between an operative position for engaging said paper storing means so as to position the plurality of individual sheets of paper within said paper storing means for feeding by said paper feed means and an inoperative position, said paper loading apparatus being characterized by first and second cam surfaces (226, 228) on said paper storing means (10), and by cam follower means (176) associated with said engaging means (168, 170) for moving said engaging means between said operative and said inoperative positions when said cam follower means engages said first and second cam surfaces on said paper storing means, said cam follower means being operative to move said engaging means towards said inoperative position when said cam follower means engages said first cam surface upon insertion of said paper storing means within said printing device, and being operative to move said engaging means towards said operative position into engagement with said paper storing means when said cam follower means engages said second cam surface upon further insertion of said paper storing means within said printing device.
Claim 2
Dependent Claim
246 words
1 . A paper loading apparatus for a printing device which includes paper advancing means for advancing a sheet of paper within the printing device, the paper loading apparatus comprising paper storing means for storing a plurality of individual sheets of paper, paper feeding means for feeding individual sheets of paper from said paper storing means along a paper feed path to said paper advancing means, and engaging means movable between an operative position for engaging said paper storing means so as to position the plurality of individual sheets of paper within said paper storing means for feeding by said paper feed means and an inoperative position, said paper loading apparatus being characterized by first and second cam surfaces (226, 228) on said paper storing means (10), and by cam follower means (176) associated with said engaging means (168, 170) for moving said engaging means between said operative and said inoperative positions when said cam follower means engages said first and second cam surfaces on said paper storing means, said cam follower means being operative to move said engaging means towards said inoperative position when said cam follower means engages said first cam surface upon insertion of said paper storing means within said printing device, and being operative to move said engaging means towards said operative position into engagement with said paper storing means when said cam follower means engages said second cam surface upon further insertion of said paper storing means within said printing device.
Claim 3
Dependent Claim
121 words
The paper loading assembly of Claim 1, in which said paper storage means includes a paper support plate arranged to be tiltable between a paper feeding position and a paper storing position, and said engaging means comprises a rod extending transversely relative to said paper feed path and having an upwardly extending member secured thereto for engaging said paper support plate to urge said paper support plate towards said paper feeding position when said engaging means is in said operative position, characterized in that said cam follower means comprises a roller (176) secured to a bracket (174) connected to said transversely extending rod (168), said roller having an axis of rotation spaced from the longitudinal axis of said transversely extending rod.
Claim 4
Dependent Claim
29 words
The paper loading assembly of Claims 1 or 2, characterized in that said first and second cam surfaces are arranged underlying a lateral edge of said paper storing means.
Claim 5
Dependent Claim
68 words
The paper loading assembly of any one of Claims 1-3, further characterized by a third cam surface (230) on said paper storing means arranged between said first and second cam surfaces, and by said cam follower means (176), when in engagement with said third cam surface, maintaining said engaging means in said inoperative position during insertion and removal of said paper storing means from within said printing device.
Claim 6
Dependent Claim
190 words
The paper loading assembly of Claims 1-4, in which said paper feed means is arranged to engage the top sheet of a stack of sheets of paper within said paper storing means, and said engaging means includes a member secured to a transversely extending rod for engaging a lower support plate of said paper storing means and urging said support plate upwardly toward said paper feed means when said engaging means is in said operative position, characterized in that said first and second cam surfaces are arranged along an underlying edge of said paper storing means, said first cam surface being arranged relative to said second cam surface such that said cam follower means engages said first cam surface (226) prior to engaging said second cam surface (228) upon said paper storing means being inserted into said printing device, and further characterized by said cam follower means (176) being spacedly positioned relative to the longitudinal axis of said transversely extending rod (168) and connected to said rod so as to be engagable by said first and second cam surfaces upon insertion of said paper storing means into said printing device.
Claim 7
Dependent Claim
