Abstract

An ink jet printer includes a cleaning blade that cleans the surface of a transport belt that attracts a sheet of recording paper by electrostatic adsorption and transports the attracted recording paper, and a pressing roller. The width of the cleaning blade is smaller than the width of the pressing roller that is located downstream of the cleaning blade, and thus, ink, paper dust, and the like that have escapes from both ends of the cleaning blade to the outside and have not been wiped off are caught by the pressing roller.

Claims (53)

1. A recording medium transport device comprising:

a transport belt that spans a plurality of rotating bodies including a first rotating body that is provided upstream in a transport direction of a recording medium for a recording area on which recording is performed by a recording section that performs recording on the recording medium, and a second rotating body that is provided downstream in the transport direction of the recording medium for the recording area, and transports the recording medium as a result of rotation of the plurality of rotating bodies;

a first cleaning section that is arranged downstream of the recording area of the recording medium in a transport direction of the transport belt, and cleans the transport belt; and

a second cleaning section that is arranged downstream of the first cleaning section in the transport direction of the transport belt, wherein

a cleaning width of the transport belt by the first cleaning section in a width direction that is a direction perpendicular to a movement direction of the transport belt is smaller than a cleaning width of the transport belt by the second cleaning section in the width direction that is the direction perpendicular to the movement direction of the transport belt, and a cleaning area by the first cleaning section is located inside a cleaning area by the second cleaning section.

2. The recording medium transport device according to claim 1 , wherein

the first cleaning section includes a blade member that wipes a belt surface of the transport belt.

3. The recording medium transport device according to claim 2 , wherein

the blade member comes into contact with the transport belt at a position at which the belt surface faces downward in a range in which the transport belt spans the second rotating body.

4. The recording medium transport device according to claim 1 , wherein

the second cleaning section includes a fabric portion that wipes off a material that has accumulated on the transport belt.

5. The recording medium transport device according to claim 1 further comprising:

a belt charging section that charges the transport belt, and

a width of a charging area in which the belt charging section charges the transport belt in the width direction that is the direction perpendicular to the movement direction of the transport belt is smaller than the cleaning width by the first cleaning section in the width direction that is the direction perpendicular to the movement direction of the transport belt, and the charging area is located inside the cleaning area by the first cleaning section.

6. The recording medium transport device according to claim 5 , wherein

the recording section includes a plurality of droplet discharge nozzles each of which discharges a droplet, and

a width of an arrangement area of the droplet discharge nozzles in the width direction that is the direction perpendicular to the movement direction of the transport belt is smaller than the width of the charging area in the width direction that is the direction perpendicular to the movement direction of the transport belt, and the arrangement area of the droplet discharge nozzles is located inside the charging area.

7. The recording medium transport device according to claim 5 , wherein

in the transport direction of the transport belt, a length of a zone from the cleaning area by the second cleaning section to the charging area is longer than a length of a zone from a cleaning area by the first cleaning section to the cleaning area by the second cleaning section.

8. The recording medium transport device according to claim 1 , wherein

the transport belt faces the recording section in a belt zone between the first rotating body and the second rotating body, and

in the transport direction of the transport belt, the recording area is located upstream of an intermediate position of the belt zone between the first rotating body and the second rotating body in the transport direction of the transport medium.

9. The recording medium transport device according to claim 1 , wherein

the recording section includes a detection section that detects the recording medium on the transport belt, downstream in the transport direction of the recording medium,

the second cleaning section performs switching between an execution state and a non-execution state of cleaning, and

a control section that controls the second cleaning section is switched from the non-execution state to the execution state when a certain time period elapses from a reference time and the detection section does not detect the recording medium.

10. A recording device comprising:
