(step S101: not), be " OFF " (step S102) under the situation that is judged as non-selected portioning function with the portioning function setting.On the other hand, being judged as (step S101: be) under the situation of having selected the portioning function, be " ON " (step S103) with the portioning function setting.
Next, read the 1st image (step S104) of 1 piece of original copy.In this execution mode, 1 piece of original copy conveyance in many original copys that are placed among the ADF15 to image reading unit 16, is read the image in the front (the 1st face) of this original copy by image reading unit 16.
Then, with image data storage (step S105) in memory.In this execution mode, the image data storage that will in the processing shown in the step S104, obtain through the front of reading original copy is in RAM13.
Next, judge whether to carry out read (the step S106) of next original copy.That is, judge in ADF15, whether to remain the original copy that is not read direct picture.
Be judged as (step S106: not), carry out double-side printing processing (step S110) under the situation about reading that need not carry out next original copy.In this execution mode, at first the back side (the 2nd face) in order to read original copy is placed into many original copys among the ADF15 by the user once more.Then, read the image at the original copy back side, form image successively based on view data on two sides with paper.Details about the double-side printing processing shown in the step S110 will be described hereinafter.
On the other hand, when in the processing shown in the step S106, being judged as (step S106: be) to carry out the reading of next original copy the time, judge whether the capacity of memory has surpassed the 1st ormal weight (step S107).Whether the data volume of particularly, judging image stored data among the RAM13 has surpassed the 1st ormal weight as predefined value.The 1st ormal weight for example is the half the value of all told of RAM13.
Do not surpass (step S107: not), turn back to the processing of step S104 under the situation of the 1st ormal weight at the capacity that is judged as memory.As a result, all remove up to the original copy that is placed on ADF15, or the data volume of the view data in the front of the original copy of storing among the RAM13 surpasses till the 1st ormal weight, image reading unit 16 continues to read the direct picture of the residue original copy of placing among the ADF15.
On the other hand, when the capacity that in the processing shown in the step S107, is judged as memory has surpassed the 1st ormal weight (step S107: be), judge whether the portioning function is " ON " (step S108).
Be judged as (step S108: not), turn back to the processing of step S104 under the situation that the portioning function is not " ON ".As a result, continue to read the image in the front of the residue original copy of placing among the ADF15 by image reading unit 16.
On the other hand, being judged as (step S108: be) under the situation that the portioning function is " ON ", be " OFF " (step S109) with the portioning function setting, turn back to the processing of step S104.As a result, continue to read the direct picture of the residue original copy of placing among the ADF15 by image reading unit 16.
As stated; According to the processing shown in step S101~S109 of Fig. 2; The data volume of the view data that obtains reading the positive image of original copy has reached under the situation of a half value of whole memory capacity of RAM13; The portioning function is changed to " OFF " from " ON ", continue to read the direct picture of the residue original copy of placing among the ADF15 by image reading unit 16.
On the other hand, do not reach in the data volume of the view data in the front of original copy under the situation of a half value of whole memory capacity of RAM13, keep the state that the portioning function is set to " ON ".
According to such structure; Be set in the portioning function under the situation of " ON "; The data volume of the view data in the front of many original copys is restricted to below whole memory capacity half the of RAM13, in RAM13, has guaranteed to be used to store the storage area of view data at the back side of each original copy.Therefore, in the RAM13 of the view data in the front that stores many original copys, can be stored in the follow-up double-side printing processing view data that the image at the back side through reading original copy is obtained reliably.As a result, the view data in the front through recycling each original copy of storing among the RAM13 and the view data at the back side, MFP1 can be the many parts of copies that unit generates many original copys with part.
Fig. 3 is the flow chart of the step of the double-side printing processing shown in the step S110 of presentation graphs 2.As stated, in double-side printing processing, read the image at the back side of original copy, form image successively based on view data on two sides with paper.
At first, judged whether to begin read (the step S201) at the back side.In this execution mode, in order to read the back side of original copy, whether judges is placed into many original copys among the ADF15 once more, and whether has indicated the reading of the back side of beginning original copy.
Be judged as (step S201: not), wait the pending indication that begins under the situation about reading that does not begin the back side.On the other hand, under the situation about reading that is judged as the beginning back side (step S201: be), read the 2nd image (step S202) of 1 piece of original copy.In this execution mode, 1 piece of original copy conveyance in many original copys that are placed on ADF15 to image reading unit 16, is read the image at the back side (the 2nd face) of this original copy by image reading unit 16.
Next, with image data storage (step S203) in memory.In this execution mode, will in the processing shown in the step S202, read the image at the original copy back side and the image data storage that obtains in RAM13.
Then, carry out 1 page duplex printing (step S204).In this execution mode, form the image that is based on the view data that stores RAM13 in the processing shown in the step S203 into respectively and based on the image of the view data corresponding with the image in the front of this image at positive and negative with paper.Formed being discharged in the discharge tray behind the image with paper.
Next, judge whether the portioning function is " ON " (step S205).Being judged as (step S205: be) under the situation that the portioning function is " ON ", transfer to the processing of step S207.
And be judged as (step S205: deny) under the situation that the portioning function is not " ON ", deleted image data (step S206).In this execution mode, the processing shown in the step S204, be used for the view data that image forms from the RAM13 deletion.
Then, judge whether to carry out read (the step S207) of next original copy.Need carry out judging whether the capacity of memory has surpassed the 2nd ormal weight (step S208) under the situation that next original copy reads (step S207: be) being judged as.Whether the data volume of particularly, judging image stored data among the RAM13 has surpassed the 2nd ormal weight as predefined value.The 2nd ormal weight for example is the value of whole memory capacity of RAM13.
Surpassed at the capacity that is judged as memory under the situation of the 2nd ormal weight (step S208: be), because memory span is overflowed and the cancellation task, processing finishes.
And do not surpass (step S208: not), turn back to the processing of step S202 under the situation of the 2nd ormal weight at the capacity that is judged as memory.As a result, continue to read the image at the back side of the residue original copy that is placed on ADF15 by image reading unit 16.
On the other hand, when in the processing shown in the step S207, being judged as (step S207: not), judge whether the portioning function is " ON " (step S209) need not continue the reading of next original copy the time.Be judged as (step S209: deny) under the situation that the portioning function is not " ON ", end process.
As stated; According to the processing shown in step S201~S209 of Fig. 3; The image at the original copy back side is read, and forms the image of the view data that obtains based on the image that reads the back side respectively and based on the image of the view data in the front of correspondence at the positive and negative with paper.Till the original copy of in ADF15, placing is all removed,, generate the copy of 1 part of many original copy through carrying out the processing shown in step S202~S207 repeatedly.
On the other hand, when in the processing shown in the step S209, being judged as the portioning function when being " ON " (step S209: be), print remaining umber (step S210).In this execution mode, on through the basis of carrying out 1 part of copy that the processing shown in step S202~S207 generates repeatedly, by a copy that part generates remainder.Particularly, recycle in the generation of the 1st part of copy and do not remained in the view data among the RAM13 after the use, remain the copy of many original copys of umber by part generation by deletion.
