Abstract

A dust removal device for continuous paper improves operability and usability for a user. The continuous paper is continuously supplied in a rightward direction, then through guide rollers, the direction of the continuous paper is reversed leftward. A downward front surface of the continuous paper is cleaned with a first dust removal device. Further, a direction of the continuous paper is reversed with a guide roller rightward. A downward back surface of the continuous paper is cleaned with a second dust removal device, and is guided to the downstream side. The two dust removal devices are provided in a vertical positional relationship in space. Dust removed with a dust removing member falls to a dust receiving member and is stored in the dust receiving member. It is possible to easily dispose the dust by pulling out the dust removal device from a cleaning position to an outside detachment position.

First claim

What is claimed is:

1. A dust removal device comprising:
a dust remover that is movable in a horizontal direction perpendicular to a conveyance direction of a continuous medium between a cleaning position, where the dust remover is in contact with the continuous medium conveyed in a horizontal posture in a predetermined space, and a detachment position away from the predetermined space.

2. A dust removal device comprising:
a dust remover that is movable between a cleaning position, where the dust remover is in contact with a continuous medium conveyed in a horizontal posture in a predetermined space, and a detachment position away from the predetermined space; and
a dust receiver that is attached to the dust remover and that receives dust removed with the dust remover, wherein
the dust remover is in contact with a lower surface of the continuous medium in the cleaning position, and
the dust receiver receives the dust removed with the dust remover from the lower surface of the continuous medium.

3. The dust removal device according to claim 2 , further comprising a conveyor that conveys the continuous medium in the predetermined space such that in a part of the continuous medium conveyed in the horizontal posture, a first surface is the lower surface, and in another part of the continuous medium conveyed in the horizontal posture, a second surface is the lower surface,
wherein the dust remover includes a first dust remover using a lower side of the part of the continuous medium in the predetermined space as a first cleaning position, and a second dust remover using a lower side of the other part of the continuous medium in the predetermined space as a second cleaning position.

4. The dust removal device according to claim 3 ,
wherein the conveyor is configured to change a conveyance path to convey the continuous medium, and
wherein, regardless of whether the conveyance path is changed or not, the first dust remover is always in contact with the first surface of the continuous medium, and the second dust remover is always in contact with the second surface of the continuous medium.

5. A printer comprising:
a medium supplier part that feeds a continuous medium;
a printer part that performs printing on the continuous medium fed from the medium supplier part;
a winder part that winds the printed continuous medium; and
a dust remover that is movable in a horizontal direction perpendicular to a conveyance direction of the continuous medium between a cleaning position, where the dust remover is in contact with the continuous medium conveyed in a horizontal posture in a predetermined space including a part of a conveyance path of the continuous medium from the medium supplier part to the printer part, and a detachment position away from the predetermined space.

6. The dust removal device according to claim 1 , further comprising:
a printer part that performs printing on the continuous medium,
wherein, the dust remover is independently movable relative to the printer part.
