Abstract
Abstract A sheet moving apparatus comprising: a track having first and second spaced side walls and a third wall therebetween to form a sheet receiving space therebetween; and a sheet feeder for moving a sheet towards the third wall and thereafter moving the sheet in a downstream direction along the track. The sheet feeder comprises a rotatable member having a surface positioned in the sheet receiving space and a rotary drive enabling the rotatable member and its surface to be rotated. The sheet feeder also includes a toggle member moveable between first and second positions with regard to the rotatable member, with the toggle member having a first member to cooperate with the surface of the rotatable member to move a sheet towards the third wall when the toggle member is in the first position, and the rotatable member and its surface are rotated. The toggle member also has a second member thereon to cooperate with the surface of the rotatable member to move the sheet in the downstream direction when the toggle member is in the second position and the rotatable member and its surface are rotated. An actuator and a resilient member are used for moving said toggle member between the first and second positions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
A sheet moving apparatus comprising: a track having first and second spaced side walls and a third wall therebetween to form a sheet receiving space therebetween; and means for moving a sheet towards said third wall and thereafter moving said sheet in a downstream direction along said track comprising: a rotatable member having a surface positioned in said sheet receiving space and means enabling said rotatable member and its surface to be rotated; a moveable member moveable between first and second positions with regard to said rotatable member; said moveable member having a first member to cooperate with said surface of said rotatable member to move a sheet towards said third wall when said moveable member is in said first position and said rotatable member and its surface are rotated, and said moveable member also having a second member to cooperate with said surface of said rotatable member to move said sheet in said downstream direction when said moveable member is in said second position and said rotatable member and its surface are rotated; and drive means for moving said moveable member between said first and second positions.
Claim 2
Dependent Claim
188 words
A sheet moving apparatus comprising: a track having first and second spaced side walls and a third wall therebetween to form a sheet receiving space therebetween; and means for moving a sheet towards said third wall and thereafter moving said sheet in a downstream direction along said track comprising: a rotatable member having a surface positioned in said sheet receiving space and means enabling said rotatable member and its surface to be rotated; a moveable member moveable between first and second positions with regard to said rotatable member; said moveable member having a first member to cooperate with said surface of said rotatable member to move a sheet towards said third wall when said moveable member is in said first position and said rotatable member and its surface are rotated, and said moveable member also having a second member to cooperate with said surface of said rotatable member to move said sheet in said downstream direction when said moveable member is in said second position and said rotatable member and its surface are rotated; and drive means for moving said moveable member between said first and second positions.
Claim 3
Dependent Claim
276 words
A sheet moving apparatus comprising: a track having first and second spaced side walls and a third wall therebetween to form a sheet receiving space therebetween; and means for moving a sheet towards said third wall and thereafter moving said sheet in a downstream direction along said track comprising: a rotatable member having a surface positioned in said sheet receiving space and means enabling said rotatable member and its surface to be rotated; a moveable member moveable between first and second positions with regard to said rotatable member; said moveable member having a first member to cooperate with said surface of said rotatable member to move a sheet towards said third wall when said moveable member is in said first position and said rotatable member and its surface are rotated, and said moveable member also having a second member to cooperate with said surface of said rotatable member to move said sheet in said downstream direction when said moveable member is in said second position and said rotatable member and its surface are rotated; and drive means for moving said moveable member between said first and second positions; said drive means comprising an actuator to move said moveable member to said first position when said actuator is energized, a resilient means to move said moveable member to said second position when said actuator is de-energized, and means for sensing when an edge of said sheet is positioned at said third wall to produce a signal which de-energizes said actuator, permitting said resilient means to move said moveable member to said second position; said rotatable member being a disc and said moveable member being a toggle member.
Claim 4
Dependent Claim
276 words
A sheet moving apparatus comprising: a track having first and second spaced side walls and a third wall therebetween to form a sheet receiving space therebetween; and means for moving a sheet towards said third wall and thereafter moving said sheet in a downstream direction along said track comprising: a rotatable member having a surface positioned in said sheet receiving space and means enabling said rotatable member and its surface to be rotated; a moveable member moveable between first and second positions with regard to said rotatable member; said moveable member having a first member to cooperate with said surface of said rotatable member to move a sheet towards said third wall when said moveable member is in said first position and said rotatable member and its surface are rotated, and said moveable member also having a second member to cooperate with said surface of said rotatable member to move said sheet in said downstream direction when said moveable member is in said second position and said rotatable member and its surface are rotated; and drive means for moving said moveable member between said first and second positions; said drive means comprising an actuator to move said moveable member to said first position when said actuator is energized, a resilient means to move said moveable member to said second position when said actuator is de-energized, and means for sensing when an edge of said sheet is positioned at said third wall to produce a signal which de-energizes said actuator, permitting said resilient means to move said moveable member to said second position; said rotatable member being a disc and said moveable member being a toggle member.
