## Abstract

Provided is an ink jet recording apparatus including a tray detachably mounted on a tray support portion of an ink jet recording apparatus in which the tray includes a main body having a support surface to support a medium, two of a first positioning pin and second positioning pin which protrude toward a mounting surface on an opposite side of a setting surface of the main body and are used at the time of mounting the main body on the tray support portion, and the tray support portion includes two of a first hole portion and second hole portion in which the two positioning pins are inserted respectively, and a placing portion on which the tray is mounted in a state where the two positioning pins are inserted in the two hole portions.

## Claims

### Claim 1

An ink jet recording apparatus comprising:
an ink discharge portion that discharges ink on a medium;
a tray that includes a main body having a support surface to support the medium, and a first positioning pin and a second positioning pin which protrude toward a surface on an opposite side of the support surface of the main body; and
a tray support portion that includes a first hole portion and a second hole portion in which the two positioning pins are inserted, and a support portion supporting the tray in a state where the two positioning pins are inserted in the two hole portions.

### Claim 2 (depends on 1)

The ink jet recording apparatus according to claim 1,
wherein the tray support portion includes a biasing mechanism which biases the two positioning pins inserted in the two hole portions in a predetermined direction.

### Claim 3 (depends on 2)

The ink jet recording apparatus according to claim 2,
wherein, in the biasing mechanism, a summed force of a biasing force with respect to the first positioning pin at the first hole portion and a biasing force with respect to the second positioning pin at the second hole portion which, compared to the first hole portion, is closer to a recording-start reference position is set so as to have a vector component toward the recording-start reference position.

### Claim 4 (depends on 3)

The ink jet recording apparatus according to claim 3,
wherein, in the biasing mechanism,
a biasing direction of the biasing force with respect to the first positioning pin at the first hole portion is a direction toward a reference line which is along a transport direction of the tray and passes the printing-start reference position, and
a biasing direction of the biasing force with respect to the second positioning pin at the second hole portion is a direction toward the printing-start reference position.

### Claim 5 (depends on 3)

The ink jet recording apparatus according to claim 3,
wherein, in the biasing mechanism,
the biasing direction of each biasing force at the first hole portion and the second hole portion is a direction of coming close to the printing-start reference position.

### Claim 6 (depends on 1)

The ink jet recording apparatus according to claim 1,
wherein the first hole portion and the second hole portion are disposed on a line along the transport direction of the tray.
