## Abstract

Meandering of a medium at a time of transporting is reduced. A recording apparatus which transports medium, and performs recording on the medium, the apparatus includes a recording unit; a medium clamping unit which is provided on a side further upstream than the recording unit in a transport direction, and clamps the medium therebetween; and a medium support unit which is provided on the side further upstream than the medium clamping unit in the transport direction, and supports the medium, in which the medium is slackened between the medium clamping unit and the medium support unit.

## Claims

### Claim 1

A recording apparatus which transports a medium, and performs recording with respect to the transported medium, the apparatus comprising:
a recording unit;
a medium clamping unit which is provided on the side further upstream than the recording unit in a transport direction, and clamps the medium therebetween; and
a medium support unit which is provided on the side further upstream than the medium clamping unit in the transport direction, and supports the medium,
wherein the medium is slackened between the medium clamping unit and the medium support unit.

### Claim 2 (depends on 1)

The recording apparatus according to claim 1,
wherein the medium is pulled out from a roll body which is wound up in a roll shape, and
wherein a transport amount of the medium is adjusted so that a predetermined tension is applied to the medium between the roll body and the medium support unit.

### Claim 3 (depends on 1)

The recording apparatus according to claim 1,
wherein a bending path is provided between the medium clamping unit and the medium support unit.

### Claim 4 (depends on 1)

The recording apparatus according to any one of claim 1,
wherein a slackening amount of the medium between the medium clamping unit and the medium support unit is adjusted by driving the medium support unit.

### Claim 5 (depends on 1)

The recording apparatus according to any one of claim 1,
wherein the medium support unit is configured so as to clamp the medium therebetween, and a clamping force of the medium support unit can be changed.
