Abstract

A printing apparatus including a transport guiding portion with high manufacturing yield, is provided. A printing apparatus includes a printing portion which is able to print on a medium, a transport portion which transports the medium, and a transport guiding portion on which a transport surface on which the medium is transported is formed and which has a plurality of bent portions, in which the transport guiding portion is provided with a first guiding member which has a bent portion and forms the transport surface on a transport direction upstream side of the medium and a second guiding member which has a bent portion and forms the transport surface on a transport direction downstream side of the medium.

Claims

1. A printing apparatus comprising:

a printing portion which is able to print on a front surface of medium;

a transport portion which transports the medium; and

a transport guiding portion that is downstream of the printing portion in a transport direction, the transport guiding portion forming a portion of a transport surface on which the medium is transported,

wherein the transport guiding portion is provided with a first guiding member which has a bent portion and forms the transport surface on a transport direction upstream side of the medium and a second guiding member which has a bent portion and forms the transport surface on a transport direction downstream side of the medium,

wherein the first guiding member and the second guiding member are in contact with a back surface of the medium that is not being printed on by the printing portion,

wherein the first guiding member and the second guiding member are supported by a common member at an end portion in a direction which intersects with the transport direction, and

wherein the first guiding member and the second guiding member are separated, and a distance between the first guiding member and the second guiding member is approximately between 0.1 mm and 1 mm.

2. The printing apparatus according to claim 1, wherein the first guiding member and the second guiding member are separated.

3. The printing apparatus according to claim 1, wherein the second guiding member has a lower height of a normal direction of the transport surface than the first guiding member.

4. The printing apparatus according to claim 1, wherein the first guiding member is a heat generating portion.

5. The printing apparatus according to claim 1, wherein the first guiding member is thicker than the second guiding member.
