Abstract
An image recording apparatus including: a controller including a position storing section storing a first position which is a position of a recording portion at a point in time earlier by a rotation required period than a point in time when the recording portion is positioned at a second position at which ejection of liquid droplets has been completed, the rotation required period being a period from a point in time when a drive command is outputted to a second motor for rotating a feeding roller to a point in time when an amount of the rotation of the feeding roller reaches a preset threshold amount; and a drive command outputting section configured to output the drive command to the second motor when the position of the recording portion has reached the first position.
Claims12
An image recording apparatus comprising:
- a recording portion configured to eject liquid droplets to record an image on a recording medium while being moved in a second direction intersecting a first direction in which the recording medium is fed;
- a feeding roller configured to feed the recording medium toward the recording portion;
- a first detecting portion configured to detect a position and a velocity of the recording portion in the second direction;
- a second detecting portion configured to detect a rotation amount of the feeding roller;
- a first motor configured to move the recording portion;
- a second motor configured to rotate the feeding roller;
- and
- a controller configured to control the movement of the recording portion by outputting a drive command to the first motor and configured to control the rotation of the feeding roller by outputting a drive command to the second motor, the controller including:
- a position storing section configured to store a first position which is a position of the recording portion, in a single movement of the recording portion, at a point in time earlier by a rotation required period than a point in time when the recording portion is positioned at a second position at which the ejection of the liquid droplets has been completed in the single movement of the recording portion, the rotation required period being a period from a point in time when the drive command is outputted to the second motor to a point in time when an amount of the rotation of the feeding roller reaches a preset threshold amount;
- and
- a drive command outputting section configured to output the drive command to the second motor when the position of the recording portion which has been detected by the first detecting portion has reached the first position.
An image recording method applied to an image recording apparatus including:
- a recording portion configured to eject liquid droplets to record an image on a recording medium while being moved in a second direction intersecting a first direction in which the recording medium is fed;
- a feeding roller configured to feed the recording medium toward the recording portion;
- a first detecting portion configured to detect a position and a velocity of the recording portion in the second direction;
- a second detecting portion configured to detect a rotation amount of the feeding roller;
- a first motor configured to move the recording portion;
- and
- a second motor configured to rotate the feeding roller, the image recording method comprising:
- storing a first position which is a position of the recording portion, in a single movement of the recording portion, at a point in time earlier by a rotation required period than a point in time when the recording portion is positioned at a second position at which the ejection of the liquid droplets has been completed in the single movement of the recording portion, the rotation required period being a period from a point in time when the drive command is outputted to the second motor to a point in time when an amount of the rotation of the feeding roller reaches a preset threshold amount;
- outputting the drive command to the second motor when the position of the recording portion which has been detected by the first detecting portion has reached the first position;
- and
- controlling a drive of the second motor on the basis of the drive command to rotate the feeding roller.
