Patent ID: 8135330

Claim:
An image recording device comprising: a sheet feeding unit that feeds a sheet member along a sheet feeding path in a sheet feeding direction; an image recording unit that records an image on the sheet member and defines a recordable area which is an area for forming the image on the sheet member; a first feeding control unit that controls the sheet feeding unit to feed the sheet member to an entry position before the image recording unit starts to record the image on the sheet member; a determination unit that determines whether the sheet member located at the entry position has a skew; and a recording control unit that controls an image forming operation of the image recording unit based on a determination result of the determination unit, wherein the sheet member has a first position and a second position which are separated from each other in the sheet feeding direction; wherein the determination unit comprises: a detection unit that detects a first one side edge position of the first position of the sheet member and a second one side edge position of the second position of the sheet member in a widthwise direction perpendicular to the sheet feeding direction; and a calculation unit that calculates a displacement amount based on the first one side edge position and the second one side edge position; wherein the image recording unit comprises: a carriage that reciprocates in the widthwise direction and supports the detection unit; and a recording head that is supported by the carriage and ejects ink droplets to the recording sheet for forming the image, the detection unit positioned upstream from the recording head in the sheet feeding direction, wherein the determination unit determines that the sheet member has the skew if the displacement amount is equal to or greater than a predetermined threshold value, wherein the first feeding control unit controls the sheet feeding unit to temporarily stop the sheet member before a leading edge of the sheet member reaches the recordable area, to restart feeding the leading edge to enter into the recordable area, and to temporarily stop the sheet member after the leading edge passes the recordable area; and wherein the detection unit is reciprocated by the carriage to detect the first one side edge position of the first position when the first feeding control unit firstly temporarily stops the sheet member, and moves with the carriage to detect the second one side edge position of the second position when the first feeding control unit secondly temporarily stops the sheet member.
