Patent ID: 7618140

Claim:
An image recording device, comprising: a conveying mechanism disposed in a predetermined conveying path comprising a plurality of rollers for conveying a recording medium by a predetermined conveying distance while nipping the recording medium; a recording unit for recording an image to the recording medium over the predetermined conveying distance; an upstream-side trailing edge detector disposed on an upstream side of the plurality of rollers for detecting a trailing edge of the recording medium based on a sensor signal generated by a first sensor which senses a presence of the recording medium; a downstream-side trailing edge detector disposed on a downstream side of the plurality of rollers for detecting the trailing edge of the recording medium based on a sensor signal generated by a second sensor which senses the presence of the recording medium; a skip warning region determination unit for determining whether or not the trailing edge of the recording medium is located in a skip warning region, based on a distance between a current position where the recording medium is currently located and a reference position of the recording medium where the upstream-side trailing edge detector detected the trailing edge of the recording medium; a storage unit for storing a correction value table for the skip warning region, the correction table comprising at least one predetermined correction value; a correction unit for receiving the at least one predetermined correction value from the correction value table, the correction unit configured to correct the predetermined conveying distance by the at least one predetermined correction value only when the trailing edge of the recording medium is in the skip warning region; an actual conveyed distance detecting unit for automatically detecting an actual conveyed distance of the recording medium between a conveyed position where the downstream-side trailing edge detector detects the trailing edge of the recording medium and the reference position; a skipping distance calculation unit for automatically calculating the skipping distance occurred on the recording medium based on the detected actual conveyed distance; and an correction value adjusting unit for automatically adjusting the predetermined correction value in the correction value table based on the calculated skipping distance.
