Abstract
A discharge mechanism includes a rotary shaft, a roller member, and a deforming unit. The roller member has a peripheral surface that is coaxial with the rotary shaft, rotates together with the rotary shaft, and discharges a medium that is in contact with the peripheral surface. The deforming unit deforms the medium in such a way that a part of the medium, the part being not in contact with the peripheral surface, passes through a position that is closer to the rotary shaft than the peripheral surface is. A part of the peripheral surface, the part being in contact with the medium, is continuously displaced in an axial direction and in a rotation direction of the rotary shaft when the roller member is rotated.
Claims20
A discharge mechanism comprising:
- a rotary shaft;
- a roller member having a peripheral surface that is coaxial with the rotary shaft, rotates together with the rotary shaft, and discharges a medium that is in contact with the peripheral surface, the peripheral surface having a constant width in an axial direction of the rotary shaft, and a cross sectional position changing in the axial direction as the roller member rotates;
- and
- a deforming unit that deforms the medium in such a way that a part of the medium, the part being not in contact with the peripheral surface, passes through a position that is closer to the rotary shaft than the peripheral surface is,
- wherein a part of the peripheral surface, the part being in contact with the medium, is continuously displaced in an axial direction and in a rotation direction of the rotary shaft when the roller member is rotated.
