Abstract
Abstract A copying paper feeding device for an intermediate tray for use in a copying machine having functions of creating a copy on both sides of a paper or printing a compound copy. In the device while being pressed by a push-out roller, copying papers fed into the intermediate tray are delivered by the rotation of the push-out roller in the direction of a copying paper aligner located downstream and upper-positioned copying papers are pushed out a little further than lower-positioned copying papers in response to a counted number of copying papers fed into the intermediate tray.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A copying paper feeding device for an intermediate tray of a copying machine, wherein pressed by a push-out roller, copying papers having one side formed with a toner image and stored temporarily within the intermediate tray are fed by the rotation of the push-out roller in the direction of a copying paper alignment means located downstream, characterized in that a means is provided for counting a number of copying papers fed into said intermediate tray and a means is provided for increasing a time of rotation of the push-out roller of the copying papers in response to the count of the number of copying papers fed into said intermediate tray, whereby upper positioned copying papers are pushed forward a little further than lower-positioned copying papers until the upper-positioned copy papers collide with said copy paper alignment means.
Claim 2
Dependent Claim
137 words
A copying paper feeding device for an intermediate tray of a copying machine, wherein pressed by a push-out roller, copying papers having one side formed with a toner image and stored temporarily within the intermediate tray are fed by the rotation of the push-out roller in the direction of a copying paper alignment means located downstream, characterized in that a means is provided for counting a number of copying papers fed into said intermediate tray and a means is provided for increasing a time of rotation of the push-out roller of the copying papers in response to the count of the number of copying papers fed into said intermediate tray, whereby upper positioned copying papers are pushed forward a little further than lower-positioned copying papers until the upper-positioned copy papers collide with said copy paper alignment means.
Claim 3
Dependent Claim
48 words
A device as claimed in claim 1, wherein after a predetermined number of copying papers are fed into said intermediate tray, the upper-positioned copying papers are pushed forward a little further than the lower-positioned copying papers until the upper-positioned copying papers collide with said copying paper alignment means.
Claim 4
Dependent Claim
145 words
A copying paper feeding device of an intermediate tray, wherein pressed by a push-out roller, copying papers having one side formed with a toner image and stored temporarily within the intermediate tray are fed by the rotation of the push-out roller in the direction of a copying paper alignment means located downstream, characterized in that a means is provided for counting a number of copying papers fed into said intermediate tray and a means is provided for increasing a time of rotation of the push-out roller in response to the number of the copying papers fed to said intermediate tray, whereby a last paper of said copying papers fed into said intermediate tray will be pushed forward a little further than other copying papers previously fed into said intermediate tray until said last paper of said copying papers collides with said copying paper alignment means.
Claim 5
Dependent Claim
145 words
A copying paper feeding device of an intermediate tray, wherein pressed by a push-out roller, copying papers having one side formed with a toner image and stored temporarily within the intermediate tray are fed by the rotation of the push-out roller in the direction of a copying paper alignment means located downstream, characterized in that a means is provided for counting a number of copying papers fed into said intermediate tray and a means is provided for increasing a time of rotation of the push-out roller in response to the number of the copying papers fed to said intermediate tray, whereby a last paper of said copying papers fed into said intermediate tray will be pushed forward a little further than other copying papers previously fed into said intermediate tray until said last paper of said copying papers collides with said copying paper alignment means.
