Abstract

A recording apparatus which includes a transport belt which transports a medium; a pressing roller which presses the medium to the transport belt; and a support unit which can support the transport belt, in which at least a part of a portion of the support unit, which faces the pressing roller through the transport belt is subjected to friction relief processing. By setting to a recording apparatus with such a configuration, it is possible to suppress an increase in friction force between the transport belt and the support unit which can support the transport belt.

First claim

What is claimed is:

1. A recording apparatus comprising:
a transport belt which configured to transport a medium;
a pressing roller which configured to press the medium onto the transport belt; and
a support unit which supports the transport belt,
wherein at least a part of a portion of the support unit that faces the pressing roller with the transport belt disposed therebetween is subjected to friction relief,
wherein the support unit is subjected to friction relief on a face which faces an end portion in a width direction of the transport belt, and
wherein the support unit is not subjected to friction relief on a face which faces a center portion in the width direction of the transport belt.

2. The recording apparatus according to claim 1 ,
wherein the support unit is subjected to reduction of the contact area with respect to the transport belt, for friction relief.

3. The recording apparatus according to claim 2 ,
wherein the support unit is provided with a protruding portion for reduction of the contact area, and an apex portion of the protruding portion is in contact with the transport belt.

4. The recording apparatus according to claim 2 ,
wherein the support unit is provided with a protruding portion including a ridge for reduction of the contact area, and the ridge is in contact with the transport belt.

5. The recording apparatus according to claim 4 ,
wherein the ridge is formed in a transport direction of the medium.

6. The recording apparatus according to claim 1 ,
wherein a sliding property improving material with which sliding properties with respect to the transport belt are improved is disposed in the support unit, for friction relief.

7. The recording apparatus according to claim 6 ,
wherein the support unit is coated with the sliding property improving material, for friction relief.

8. The recording apparatus according to claim 6 ,
wherein the support unit is formed of the sliding property improving material, for friction relief.

9. The recording apparatus according to claim 1 ,
wherein the transport belt has a support face which faces the medium and on which an adhesive is painted.
