Abstract

A photo-curing inkjet printer includes a bed, a discharger, a light applicator, and a conveyor. The bed includes a printable region defined in advance. A substrate is placed on the bed. The discharger discharges photo-curable ink. The light applicator applies light. The conveyor conveys one of the bed and the discharger relative to the other one of the bed and the discharger in a conveyance direction. The discharger includes a row of nozzles aligned in the conveyance direction. The nozzles discharge the photo-curable ink. A length of the bed measured from a start end of the bed to a start end of the printable region is longer in the conveyance direction than a length calculated by subtracting a maximum pass width from a length of the row of nozzles of the discharger.

Claims (22)

1. A photo-curing inkjet printer comprising:

a casing including a bottom wall;

a bed on which a substrate is to be placed, the bed being disposed above the bottom wall and including a printable region;

a discharger disposed above the bed to discharge photo-curable ink in the printable region and onto the substrate placed on the bed;

a light applicator disposed above the bed to apply light to the photo-curable ink discharged onto the substrate;

a conveyor to convey one of the bed and the discharger relative to the other one of the bed and the discharger in a conveyance direction; and

a controller to control the discharger, the light applicator, and the conveyor; wherein

a length of the bottom wall is longer than a length of the bed in the conveyance direction;

the discharger includes a row of nozzles aligned in the conveyance direction to discharge the photo-curable ink;

a length of the bed measured from a start end of the bed to a start end of the printable region is longer in the conveyance direction than a length calculated by subtracting a maximum pass width from a length of the row of nozzles of the discharger; and

the length of the bed measured from the start end of the bed to the start end of the printable region is equal to or shorter than a length of the light applicator in the conveyance direction.

2. The photo-curing inkjet printer according to claim 1 , wherein the conveyor moves the bed relative to the discharger in the conveyance direction.

3. The photo-curing inkjet printer according to claim 1 , wherein the bed is smaller in area than the bottom wall.

4. The photo-curing inkjet printer according to claim 1 , wherein a length of the bed measured from a finish end of the bed to a finish end of the printable region is longer in the conveyance direction than the length of the row of nozzles of the discharger.

5. The photo-curing inkjet printer according to claim 1 , further comprising a reflected light protector disposed between the start end of the bed and the start end of the printable region to reduce reflected light incident on the discharger.

6. The photo-curing inkjet printer according to claim 1 , wherein the bed includes:

a body on which the printable region is located; and

a start end member attached to a start end of the body facing in the conveyance direction.

7. The photo-curing inkjet printer according to claim 1 , wherein the length of the bed measured from the start end of the bed to the start end of the printable region is longer than a length of a lower surface of the discharger in the conveyance direction.

8. The photo-curing inkjet printer according to claim 1 , further comprising:

a guide rail disposed above the bed and extending in a scanning direction perpendicular or substantially perpendicular to the conveyance direction; and

a carriage slidable along the guide rail and equipped with the discharger and the light applicator.
