Medium supporting unit, recording apparatus, and medium supporting method
A medium supporting unit includes a supporting unit which can support a medium, and a pressing unit which can press the medium which is supported by the supporting, in which a coefficient of static friction of a contact face with the medium in the pressing unit is larger than that of a contact face with the medium in the supporting unit. By configuring such a medium supporting unit, it is possible to suppress floating of the medium.
1. A medium supporting unit comprising:
a supporting unit which can support a medium; and
a pressing unit which can press the medium supported by the supporting unit,
wherein a coefficient of static friction of a contact face with the medium in the pressing unit is larger than that of a contact face with the medium in the supporting unit,
wherein a painting layer of which a coefficient of static friction is larger than that of the contact face with the medium in the supporting unit is formed on the contact face with the medium in the pressing unit.
2. The medium supporting unit according to claim 1 ,
wherein the contact face with the medium in the pressing unit is formed of a soft polymeric substance.
3. A recording apparatus comprising:
the medium supporting unit according to claim 2 ; and
a recording unit which can perform recording on the medium which is supported by the medium supporting unit.
4. The medium supporting unit according to claim 1 ,
wherein the contact face with the medium in the pressing unit is formed with unevenness.
5. A recording apparatus comprising:
the medium supporting unit according to claim 4 ; and
a recording unit which can perform recording on the medium which is supported by the medium supporting unit.
6. The medium supporting unit according to claim 1 ,
wherein the contact face with the medium in the supporting unit is formed of a hard polymeric substance.
7. A recording apparatus comprising:
the medium supporting unit according to claim 6 ; and
a recording unit which can perform recording on the medium which is supported by the medium supporting unit.
8. The medium supporting unit according to claim 1 ,
wherein a coefficient of static friction on the entire surface of the pressing unit is larger than that of the contact face with the medium in the supporting unit.
9. A recording apparatus comprising:
the medium supporting unit according to claim 8 ; and
a recording unit which can perform recording on the medium which is supported by the medium supporting unit.
10. A recording apparatus comprising:
the medium supporting unit according to claim 1 ; and
a recording unit which can perform recording on the medium which is supported by the medium supporting unit.
11. A medium supporting method in a medium supporting unit which includes a supporting unit which can support a medium, and a pressing unit which can press the medium supported by the supporting unit, the method comprising:
setting a coefficient of static friction of a contact face with the medium in the pressing unit to be larger than that of a contact face with the medium in the supporting unit, and
forming on the contact face with the medium in the pressing unit a painting layer of which a coefficient of static friction is larger than that of the contact face with the medium in the supporting unit.
