## Abstract

A medium support unit for supporting a medium on which a printing apparatus performs printing includes a support portion having a support surface for supporting the medium, a heating portion heating the support portion, and a main body portion on which the support portion is mounted, wherein heat conductivity of a mounting portion as a portion of the main body portion on which the support portion is mounted is lower than heat conductivity of the support portion.

## Claims

### Claim 1

A medium support unit for supporting a medium on which a printing apparatus performs printing, the medium support unit comprising:
a support portion having a support surface for supporting the medium;
a heating portion heating the support portion;
a main body portion on which the support portion is mounted; and
a frame portion capable of pressing the medium supported on the support portion by being mounted on a receiver provided on the main body portion,
wherein heat conductivity of a mounting portion as a portion of the main body portion on which the support portion is mounted is lower than heat conductivity of the support portion.

### Claim 2 (depends on 1)

The medium support unit according to claim 1,
wherein the main body portion has the mounting portion and a non-mounting portion as a portion other than the mounting portion, which are made of different materials, and
the heat conductivity of the mounting portion is lower than heat conductivity of the non-mounting portion.

### Claim 3 (depends on 2)

A printing apparatus comprising:
the medium support unit according to claim 2; and
a printing portion that performs printing on the medium supported on the medium support unit.

### Claim 4 (depends on 1)

The medium support unit according to claim 1,
wherein the main body portion has the mounting portion and a non-mounting portion as a portion other than the mounting portion, which are made of the same material.

### Claim 5 (depends on 4)

A printing apparatus comprising:
medium support unit according to claim 4; and
a printing portion that performs printing on the medium supported on the medium support unit.

### Claim 6 (depends on 1)

The medium support unit according to claim 1,
wherein the main body portion is provided with a hollow portion between an outer circumferential surface of the main body portion and the heating portion.

### Claim 7 (depends on 6)

A printing apparatus comprising:
the medium support unit according to claim 6; and
a printing portion that performs printing on the medium supported on the medium support unit.

### Claim 8 (depends on 1)

The medium support unit according to claim 1,
wherein the support portion is made of a highly heat conductive material having higher heat conductivity than heat conductivity of a material forming the main body portion.

### Claim 9 (depends on 8)

A printing apparatus comprising:
the medium support unit according to claim 8; and
a printing portion that performs printing on the medium supported on the medium support unit.

### Claim 10 (depends on 1)

The medium support unit according to claim 1,
wherein a heating region of the heating portion is divided on the support surface and a temperature is capable of being changed for every divided region.

### Claim 11 (depends on 10)

A printing apparatus comprising:
medium support unit according to claim 10; and
a printing portion that performs printing on the medium supported on the medium support unit.

### Claim 12 (depends on 1)

A printing apparatus comprising:
the medium support unit according to claim 1; and
a printing portion that performs printing on the medium supported on the medium support unit.
