Abstract

An image recording device that makes it possible to accurately position images on the front and reverse surfaces of a recording medium even when there is an error in length in the direction of conveyance of the recording medium. The image recording device is equipped with a paper supply part, a paper discharge part, a table movement mechanism, which moves ten tables disposed at regular intervals along a circulation path, an image recording part, which records an image on printing paper on top of the table that is moved by this table movement mechanism, an inversion part, which inverts the printing paper, and a transport mechanism, which transports the printing paper inverted by the inversion part to the paper supply part.

Claims

1. An image recording device that records images on a front surface and a reverse surface of a recording medium, the image recording device comprising:

recording medium holding means that holds the recording medium;

a movement mechanism that moves the recording medium holding means;

a recording medium attachment part that attaches the recording medium to the recording medium holding means that is moved by driving by the movement mechanism;

a recording medium supply part that supplies the recording medium not recorded with an image to the recording medium attachment part;

a recording head that records an image on the recording medium that is attached to the recording medium holding means by the recording medium attachment part and held by the recording medium holding means;

a detection part that detects a size of the recording medium of which the front surface is recorded with the image by the recording head;

an inversion part that inverts, on a basis of a switch back method, the recording medium of which the front surface is recorded with the image by the recording head, such that a front end of the recording medium serves as a back end;

a recording medium transport mechanism that transports the recording medium inverted by the inversion part to the recording medium attachment part;

a control part that adjusts, on a basis of the size of the recording medium, the size being detected by the detection part, an image recording position on the reverse surface of the recording medium by the recording head; and

a recording medium discharge part that discharges the recording medium of which the front surface and the reverse surface are recorded with the images by the recording head.

2. The image recording device according to claim 1, wherein

the recording medium holding means is a plurality of tables that support the recording media, and

the tables move along a circulation path with use of:

a pair of roller members;

a drive mechanism that rotationally drives the pair of roller members; and

an endless transport mechanism that has an endless rope body wound on the pair of roller members.

3. The image recording device according to claim 2, wherein

the recording medium attachment part alternately attaches to the plurality of tables a recording medium not recorded with an image and a recording medium of which a front surface is recorded with an image.

4. The image recording device according to claim 3, wherein

the recording medium supply part intermittently supplies the recording medium not recorded with an image to the recording medium attachment part;

and

the recording medium transport mechanism transports, between the recording media not recorded with an image, the recording media being intermittently supplied by the recording medium supply part, the recording medium of which a front surface is recorded with an image.

5. The image recording device according to claim 2, wherein

the recording medium attachment part is provided with a positioning mechanism that comes into abutting contact with a front end of a recording medium to position the recording medium.

6. The image recording device according to claim 2, wherein

the detection part is a scanner that scans the image recorded by the recording head or a detection patch.

7. The image recording device according to claim 2, wherein

the inversion part is arranged in a same direction as the paper discharge part.

8. The image recording device according to claim 2, wherein

the inversion part is arranged in a same direction as the recording medium attachment part, and

a stocker part that temporarily stocks a recording medium on which single-surface printing is complete, and a transport mechanism that transports the recording medium temporarily stocked by the stocker part to the recording medium attachment part are disposed adjacent to the inversion part.
