Abstract
A medium stacking sheet is installed on a rotation shaft of a medium separating and stacking apparatus for stacking or dispensing a medium. The medium stacking sheet includes a body fixed to the rotation shaft and having a plurality of rotation holes which are spaced apart from each other in a rotation direction of the rotation shaft, and a plurality of vanes each including a vane pin rotatably installed in a corresponding rotation hole and a vane piece coupled to the vane pin to stack the medium.
Claims15
A medium stacking sheet installed on a rotation shaft of a medium separating and stacking apparatus for stacking or dispensing a medium, comprising:
- a body fixed to the rotation shaft and having a plurality of rotation holes which are spaced apart from each other in a rotation direction of the rotation shaft;
- and
- a plurality of vanes each including a vane pin rotatably installed in a corresponding rotation hole and a vane piece coupled to the vane pin to stack the medium,
- wherein the body further includes:
- a support plate having a central hole to which the rotation shaft is coupled, the rotation holes being disposed in an edge portion of the support plate;
- a plurality of stopper bump portions provided to be circumferentially spaced apart from each other in a central portion of the support plate;
- and
- a plurality of stopper groove portions each of which is formed between the adjacent stopper bump portions so that at least a portion of the vane piece is rotated within a predetermined angular range when the vane piece is unfolded, and
- wherein the vane piece includes:
- a vane portion;
- a coupling portion provided at one end of the vane portion to be coupled to the vane pin;
- a stopper portion protruded from the coupling portion, the stopper portion being located in each of the stopper groove portions of the body to limit rotation of the vane piece.
A medium stacking sheet installed on a rotation shaft of a medium separating and stacking apparatus for stacking or dispensing a medium, comprising:
- a body having an outer circumferential surface and a plurality of mounting grooves formed on the outer circumferential surface, the body being rotatably fixed to the rotation shaft;
- a plurality of vanes each including a vane pin rotatably coupled in a corresponding mounting groove and a vane piece fixed to the vane pin to stack the medium;
- and
- a plurality of stoppers each provided on the body to limit a rotation of the vane pin within a predetermined angle range when the vane piece is unfolded,
- wherein the vane pin includes locking pieces provided in an axial direction of the rotation shaft, and
- wherein each of the locking pieces includes:
- a first locking portion supported by a corresponding stopper when the vane piece is unfolded;
- a second locking portion disposed opposite to the first locking portion and smaller than the first locking portion to avoid interference with the corresponding stopper.
A medium separating and stacking apparatus comprising:
- a rotation shaft configured to be rotated when stacking or dispensing a medium;
- and
- a medium stacking sheet installed on the rotation shaft,
- wherein the medium stacking sheet includes:
- a body having an outer circumferential surface and a plurality of mounting grooves formed on the outer circumferential surface, the body being rotatably fixed to the rotation shaft;
- a plurality of vanes each including a vane pin rotatably coupled in a corresponding mounting groove and a vane piece fixed to the vane pin to stack the medium;
- and
- a plurality of stoppers each provided on the body to limit a rotation of the vane pin within a predetermined angle range when the vane piece is unfolded,
- wherein the vane pin includes locking pieces provided in an axial direction of the rotation shaft, and
- wherein each of the locking pieces includes:
- a first locking portion supported by a corresponding stopper when the vane piece is unfolded;
- a second locking portion disposed opposite to the first locking portion and smaller than the first locking portion to avoid interference with the corresponding stopper.
