## Abstract

A recording apparatus includes a recording unit which performs recording on a recording medium; and a movable body which includes a support portion that supports the recording medium and which moves along a guide shaft, in which the movable body includes a bearing which is supported by the guide shaft and is movable in an opposite direction from gravity in relation to the guide shaft, and a load center which receives the moving force for the movement and is positioned on a straight line along a movement direction, where the straight line intersects a straight line in a gravity direction which passes through a center of gravity of the movable body.

## Claims

### Claim 1

A recording apparatus comprising:
a recording unit configured to record on a recording medium while moving in a scanning direction;
a first guide shaft;
a second guide shaft; and
a movable body that supports the recording medium and moves along the first guide shaft and the second guide shaft; wherein
the movable body includes a first bearing supported by the first guide shaft and a second bearing supported by the second guide shaft, wherein the second bearing is supported so as to be movable in the scanning direction, the second bearing including a bearing surface with a generally planar portion and at least one curved surface extending from the generally planar portion to at least partially surround the second guide shaft.

### Claim 2 (depends on 1)

The recording apparatus according to claim 1, wherein a shape of the first bearing includes a gable shape.

### Claim 3 (depends on 1)

The recording apparatus according to claim 1, wherein the first bearing is movable in a gravity direction.

### Claim 4 (depends on 1)

The recording apparatus according to claim 1, wherein a shape of the second bearing includes a half cylinder shape.

### Claim 5 (depends on 1)

The recording apparatus according to claim 1, wherein the second bearing is movable in a gravity direction.

### Claim 6 (depends on 1)

The recording apparatus according to claim 1, wherein the shape of the first bearing includes a gable shape and the shape of the second bearing includes a half cylinder shape.

### Claim 7 (depends on 1)

The recording apparatus according to claim 1, further comprising:
a belt for moving the movable body, wherein the belt is located between the first guide shaft and the second guide shaft.

### Claim 8 (depends on 7)

The recording apparatus according to claim 7, further comprising:
a belt holder that receives a first force from the belt, wherein the belt holder is disposed on the movable body between a center of gravity of the movable body and the first and second bearings in a gravity direction.

### Claim 9 (depends on 8)

The recording apparatus according to claim 8, wherein the first force is greater than a second force that the first and second bearings receive from the first and second guide shafts.

### Claim 10 (depends on 1)

The recording apparatus according to claim 1, wherein the first bearing is supported so as to be constrained in the scanning direction.
