Abstract

An image recording device includes a drive roller, a driven roller, a recording unit and a control unit. The driven roller is configured and arranged with respect to the drive roller so that the recording medium is grasped between the drive roller and the driven roller. The recording unit is configured and arranged to record an image on the recording medium arranged further to a downstream side than the drive roller in a first direction. When the control unit stops conveying of the recording medium in the first direction, the control unit is configured to stop conveying of the recording medium in a state in which an area of the recording medium different from an area, in which the image is planned to be recorded after a timing at which conveying of the recording medium is stopped, is in contact with the driven roller.

First claim

What is claimed is:

1 . An image recording device comprising:
a drive roller configured and arranged to convey recording medium by rotating; a driven roller configured and arranged with respect to the drive roller so that the recording medium is grasped between the drive roller and the driven roller; a recording unit configured and arranged to record an image on the recording medium arranged further to a downstream side than the drive roller in a first direction which is the recording medium conveyance direction; and a control unit configured to control the recording unit and the drive roller to record the image on the recording medium while conveying the recording medium in the first direction, wherein when the control unit stops conveying of the recording medium in the first direction, the control unit is configured to stop conveying of the recording medium in a state in which an area of the recording medium different from an area, in which the image is planned to be recorded after a timing at which conveying of the recording medium is stopped, is in contact with the driven roller.

2 . The image recording device according to claim 1 , wherein
when the control unit stops conveying of the recording medium in the first direction, the control unit is configured to stop conveying of the recording medium in a state in which, an area of the recording medium between an area, in which the recording unit has already recorded the image, and the area, in which the image is planned to be recorded after the timing at which conveying of the recording medium is stopped, is in contact with the driven roller.

3 . The image recording device according to claim 1 , wherein
the recording unit is configured and arranged to record the image on the recording medium having an already printed print image, and when the control unit stops conveying of the recording medium in the first direction, the control unit is configured to stop conveying of the recording medium in a state in which, an area of the recording medium, which is an area in which the print image is printed and which is different from the area in which an image is planned to be recorded after the timing at which conveying of the recording medium is stopped, is in contact with the driven roller.

4 . The image recording device according to claim 1 , wherein
when the control unit stops conveying of the recording medium in the first direction, the control unit is configured to convey a prescribed amount of the recording medium in a second direction reverse to the first direction after stopping conveying of the recording medium in the first direction and to stop conveying of the recording medium in a state in which an area of the recording medium different from the area, in which the image is planned to be recorded after the timing at which conveying of the recording medium is stopped, is in contact with the driven roller.

5 . The image recording device according to claim 4 , wherein
the control unit is configured to control the drive roller to start conveying the recording medium in the second direction within 2.5 seconds after conveying of the recording medium in the first direction stops.

6 . The image recording device according to claim 1 , wherein
the control unit is configured to stop conveying of the recording medium in the first direction when an area of the recording medium different from the area, in which the image is planned to be recorded from after the timing at which conveying of the recording is stopped, reaches the driven roller as the recording medium is conveyed in the first direction.

7 . The image recording device according to claim 4 , further comprising:
an exterior member housing the drive roller, the driven roller, and the recording unit; a door provided on the exterior member; a locking mechanism configured and arranged to lock the door; and a user interface configured and arranged to receive instructions from a user and to transmit the instructions to the control unit, wherein the control unit is configured to control the drive roller to stop conveying of the recording medium in the first direction in accordance with a stop instruction from the user, to control the locking mechanism to lock the door until conveying of the recording medium in the second direction stops, and to unlock the door after conveying of the recording medium in the second direction has stopped.

8 . The image recording device according to claim 1 , wherein
the driven roller has rubber on an outer circumference surface, and a surface of the recording medium on which the image is recorded is contacted by the outer circumference surface.

9 . The image recording device according to claim 1 , wherein
the driven roller has a tetrafluoro ethylene perfluoro alkyl vinyl ether copolymer on an outer circumference surface, and a surface of the recording medium on which the image is recorded is contacted by the outer circumference surface.

10 . An image recording method comprising:
recording an image on a recording medium by a recording unit arranged further to a downstream side in a first direction, which is a conveyance direction of the recording medium, than a drive roller while rotating the drive roller to convey the recording medium grasped between the drive roller and a driven roller; and stopping conveying of the recording medium in a state in which an area of the recording medium different from an area, in which the image is planned to be recorded after a timing at which conveying of the recording medium is stopped, is in contact with the driven roller.
