Abstract

The image recording apparatus forms an image on each of at least two kinds of printing media of different widths by ejecting ink droplets thereon. The apparatus includes an ink ejection unit that ejects ink toward a front surface of a printing medium, a pair of ink receivers that receive the ink ejected outside both side edges of the printing medium in a width direction perpendicular to a transport direction of the printing medium and a first shield plate that is arranged outside a first edge of the printing medium in the width direction perpendicular to the transport direction of the printing medium, and moves in parallel to the front surface of the printing medium and in the width direction perpendicular to the transport direction of the printing medium in accordance with a position of an edge of each of the at least two kinds of printing media of the different widths.

Claims

1. An image recording apparatus that forms an image on each of at least two kinds of printing media of different widths by ejecting ink droplets thereon, comprising:

ink ejection means that ejects ink toward a front surface of a printing medium;

a pair of ink receivers that receive the ink ejected outside both side edges of the printing medium in a width direction perpendicular to a transport direction of the printing medium; and

a first shield plate that is arranged outside a first edge of the printing medium in the width direction perpendicular to the transport direction of the printing medium, and moves in parallel to the front surface of the printing medium and in the width direction perpendicular to the transport direction of the printing medium in accordance with a position of an edge of each of the at least two kinds of printing media of the different widths.

2. The image recording apparatus according to claim 1, wherein each of the pair of ink receivers includes a movable ink receiver that moves in the width direction perpendicular to the transport direction of the printing medium in accordance with a width of each of the at least two kinds of printing media of different widths.

3. The image recording apparatus according to claim 1, further comprising:

a printing stage that sucks a back surface of the printing medium that is opposite to the front surface and supports the printing medium, wherein the pair of ink receivers are formed in the printing stage at positions corresponding to both side edges of the at least two kinds of printing media of the different widths.

4. The image recording apparatus according to claim 1, wherein the at least two kinds of printing media of different widths are each transported with reference to a second edge opposite to the first edge of the printing medium.

5. The image recording apparatus according to claim 1, further comprising:

a second shield plate that moves in parallel to the front surface of the printing medium and in the width direction perpendicular to the transport direction of the printing medium, wherein the at least two kinds of printing media of the different widths are each transported with reference to a center thereof in the width direction perpendicular to the transport direction.

6. The image recording apparatus according to claim 1, wherein the ink ejection means reciprocates in parallel to the front surface of the printing medium and in the width direction perpendicular to the transport direction of the printing medium, and forms an image on the printing medium.

7. The image recording apparatus according to claim 1, wherein the first shield plate includes an ink absorber that absorbs the ink on a surface of the ink absorber, the surface of the ink absorber being on a side on which the ink ejection means is arranged in a direction vertical to the front surface of the printing medium.

8. The image recording apparatus according to claim 7, further comprising ejection position control means that allows the ink ejection means to eject the ink onto a specific position of the ink absorber of the first shield plate upon flushing operation, wherein the specific position is changed for every flushing operation.
