IMAGE RECORDING APPARATUS AND SHEET SEPARATING/CUTTING METHOD THEREBY
This is an image recording apparatus for cutting a continuous sheet by a sheet cutting unit after recording images on the continuous sheet, which comprises: a defect detecting unit for detecting a defective image recorded on the continuous sheet; and a sheet cutting position control unit for modifying cutting conditions and enabling the sheet cutting unit to cut the continuous sheet, based on a detection result of the defect detecting unit.
1 . An image recording apparatus for cutting a continuous sheet by a sheet cutting unit after recording images on the continuous sheet, comprising:
a defect detecting unit for detecting a defective image recorded on the continuous sheet; and
a sheet cutting position control unit for modifying cutting conditions and enabling the sheet cutting unit to cut the continuous sheet, based on a detection result of the defect detecting unit.
2 . The image recording apparatus according to claim 1 , further comprising:
an operation processing device; and
a control unit comprising at least an operation processing device and a storage unit for storing a control program in advance,
wherein
the control unit functions as the sheet cutting position control unit by enabling the operation processing device to executing the control program.
3 . The image recording apparatus according to claim 1 , wherein
when the defect detecting unit does not detect the defect, the sheet cutting position control unit enables the sheet cutting unit to cut the continuous sheet with a prescribed length and
when the defect detecting unit detects the defect, the sheet cutting position control unit enables the sheet cutting unit to cut the continuous sheet with longer length than the prescribed length.
4 . The image recording apparatus according to claim 3 , wherein
the sheet cutting position control unit enables the sheet cutting unit to cut the continuous sheet with longer length than the prescribed length after the defect detecting unit detects the defect.
5 . The image recording apparatus according to claim 1 , wherein
when the defect detecting unit does not detect the defect, the sheet cutting position control unit enables the sheet cutting unit to cut the continuous sheet with a prescribed length and
when the defect detecting unit detects the defect, the sheet cutting position control unit enables the sheet cutting unit to cut the continuous sheet in unparallel with width direction of the continuous sheet.
6 . The image recording apparatus according to claim 1 , wherein
when the defect detecting unit does detect the defect, the sheet cutting position control unit enables the sheet cutting unit to cut the continuous sheet in such a way that a part of it may become longer than the prescribed length.
7 . The image recording apparatus according to claim 1 , further comprising
a sheet reception unit having an edge and an inclined bottom, for receiving the continuous sheet in such a way one ends of the continuous sheet cut by the sheet cutting unit at the edge can be uniformly arranged by its own weight.
8 . A sheet separating/cutting method by an image recording apparatus for cutting a continuous sheet by a sheet cutting unit after recording images on the continuous sheet, comprising:
detecting a defective image recorded on the continuous sheet; and
modifying cutting conditions and enabling the sheet cutting unit to cut the continuous sheet, based on the defection result.
9 . The sheet separating/cutting method according to claim 8 , wherein
cutting the continuous sheet with a prescribed length when not detecting the defect as the detection result and
cutting the continuous sheet in a different cutting method from when not detecting the defect when detecting the defect.
