Then, according to needs yardage that is calculated by yardage calculating unit 63 and the paper information that is stored in the paper information memory unit 65, paper suitability degree judging part 66 judges to place the current scrolling page or leaf of uncoiler 2 whether to be suitable for carrying out print out task.When the remaining sheet length of the current scrolling page or leaf that places uncoiler 2 is enough (step 205 be), paper suitability degree judging part 66 shows and illustrates that print out task can carry out (step 206) placing on the rolling page or leaf of uncoiler 2 carrying out on the demonstration/functional unit 12.
When the user operates demonstration/functional unit 12 and provides the instruction of carrying out print out task in response to the demonstration of " print out task can be performed " (being in the step 207), control assembly 11 is control paper transfer member 14 and image forming part 15 in by external equipment attaching parts 16 control uncoilers 2 and rewinding machine 3, thereby carries out print processing (step 208).When print processing finished, according to the signal from paper transfer member 14, image forming part 15 etc., remaining sheet length detection parts 64 detected the remaining sheet length (step 209) of the rolling page or leaf that is used to print.According to detected remaining sheet length, paper information memory unit 65 upgrades the remaining sheet length (step 210) corresponding with the paper identifier of the rolling page or leaf that places uncoiler 2.So processing finishes.
On the contrary, paper suitability degree judging part 66 draw the rolling page or leaf that places uncoiler 2 the remaining sheet curtailment conclusion the time (step 205 not), though or have enough remaining sheet length but user when not being given in the instruction that prints on the rolling page or leaf that places on the uncoiler 2 (step 207 not) at it, paper alternative pack 67 is carried out paper and is selected to handle (step 211).
In paper was selected to handle, paper alternative pack 67 at first obtained all paper identifiers that are stored in the paper information memory unit 65, and the remaining sheet length (step 212) corresponding with the paper identifier.Next, paper alternative pack 67 with the ascending order of the remaining sheet length obtained accordingly to paper identifier classify (step 213), and with the first paper identifier, promptly the shortest paper identifier of remaining sheet length is set to first comparison object (step 214).
Then, 67 pairs of paper alternative packs be set to comparison object the paper identifier residue length with need yardage to compare.Be not less than when needing yardage in remaining sheet length (being in the step 215), paper alternative pack 67 is judged the paper identifier target (step 216) as an alternative that will be set to comparison object.
On the contrary, the result who supposes comparison is a remaining sheet length less than the conclusion that needs yardage (in the step 215 not).In this case, when having the paper identifier that is not compared as yet (being in the step 217), the next one in the paper identifier of having classified is set to comparison object (step 218).The remaining sheet length of paper identifier is compared with the needs yardage in the same manner.
The remaining sheet length of supposing all paper identifiers that are stored in the paper information memory unit 65 and the comparative result that needs yardage draw all remaining sheet length all less than the conclusion that needs yardage (in the step 217 not).In this case, when a plurality of print out task were selected as being ordered print out task that be about to carry out (being in the step 219), paper alternative pack 67 was carried out on demonstrations/functional unit 12 and is shown to come the requirement user to provide the print out task of reselecting execution soon or the instruction (step 220) of being replaced current paper by new paper.So when the user provides the instruction of reselecting print out task (in the step 221 not), paper alternative pack 67 turns back to step 201 and shows the tabulation of print out task and wait for that the user reselects task.In the print out task tabulation of reselecting demonstration, show the unusable paper length and the number of paper that calculate at each print out task, for example shown in Figure 11 C for task.
When the user provides the instruction of replacing current paper by new paper (being in the step 221), or at single print out task as (in the step 219 not) by the print out task of command execution and when selected, new paper is confirmed as replacing target (step 222).
At the paper of target as an alternative is to select to handle when determining by paper, and paper alternative pack 67 makes demonstration/functional units 12 demonstrate current paper must be replaced (step 223) by the paper identifier of paper that is defined as replacing target or new paper.
Paper is replaced (step 224) by the user to the response that shows.When paper is replaced by new paper (being in the step 225), paper information memory unit 65 is provided with paper identifier (step 226) for new paper, is provided as the default value (step 227) of its remaining sheet length, and the paper identifier that is provided with of storage and the remaining sheet length (step 227) of setting.The paper identifier can automatically generate, perhaps can be by the user by 12 inputs of demonstration/functional unit.
Then, control assembly 11 in by external equipment attaching parts 16 control uncoilers 2 and rewinding machine 3 control paper transfer member 14 and image forming part 15 to carry out print processing (step 208).When print processing finished, according to the signal from paper transfer member 14, image forming part 15 etc., remaining sheet length detection parts 64 detected the remaining sheet length (step 209) of the rolling page or leaf that is used to print.According to the remaining sheet length that detection obtains, paper information memory unit 65 upgrades the remaining sheet length (step 210) corresponding with the paper identifier of the rolling page or leaf that places uncoiler 2.So processing finishes.
(the 3rd exemplary embodiment)
In second exemplary embodiment, the number of paper that is printed in each print out task etc. is not calculated when the user selects task.In the 3rd exemplary embodiment, the number of paper that is printed in each print out task etc. was calculated before user's selection task.In the example that the 3rd exemplary embodiment is described, except the operation of control assembly 11, identical in structure of control assembly 11 or the like and first and second exemplary embodiments.Therefore omitted description, and only operation has been described structure.

When communication component 13 receives print out task (being in the step 301), control assembly 11 is accepted to be accepted print out task that parts 61 receive and print out task is stored in the memory cell 17 (step 302) by task.Task analysis parts 62 are analyzed print out task, and specify the yardage and the number of paper (step 303) of each page that will be printed that is used to carry out print out task.According to the yardage of each page of appointment and the number of paper of appointment, yardage calculating unit 63 calculates and needs yardage (step 304).In this case, yardage calculating unit 63 calculates and comprises and printing or paper is cut out the yardage that needs of required paper edge.The acceptance of each print out task or similar operations are handled executed in parallel with other.
When the user carried out print out task by demonstration/functional unit 12 input instruction after print out task is accepted, control assembly 11 showed print out task tabulate (step 311) on demonstrations/functional unit 12.For example, the print out task tabulation is shown as shown in Figure 14.
When print out task that the user selects to be about to be performed from the tabulation of shown print out task (being in the step 312), yardage calculating unit 63 calculates and needs yardage (step 313).In this case, yardage calculating unit 63 calculates and comprises and printing or paper is cut out the yardage that needs of required paper edge.
Then, according to needs yardage that is calculated by yardage calculating unit 63 and the paper information that is stored in the paper information memory unit 65, paper suitability degree judging part 66 judges to place the current scrolling page or leaf of uncoiler 2 whether to be suitable for carrying out print out task.When the remaining sheet length of the current scrolling page or leaf that places uncoiler 2 is enough (step 314 be), paper suitability degree judging part 66 shows and illustrates that print out task can carry out (step 315) placing on the rolling page or leaf of uncoiler 2 carrying out on the demonstration/functional unit 12.
When the user operates demonstration/functional unit 12 and provides the instruction of carrying out print out task in response to the demonstration of " print out task can be performed " (being in the step 316), control assembly 11 is control paper transfer member 14 and image forming part 15 in by external equipment attaching parts 16 control uncoilers 2 and rewinding machine 3, thereby carries out print processing (step 317).When print processing finished, according to the signal from paper transfer member 14, image forming part 15 etc., remaining sheet length detection parts 64 detected the remaining sheet length (step 318) of the rolling page or leaf that is used to print.According to detected remaining sheet length, paper information memory unit 65 upgrades the remaining sheet length (step 319) corresponding with the paper identifier of the rolling page or leaf that places uncoiler 2.So processing finishes.
On the contrary, when paper suitability degree judging part 66 draws the conclusion of remaining sheet curtailment of the rolling page or leaf that places uncoiler 2 (step 314 not), though or have enough remaining sheet length but user when not being given in the instruction that prints on the rolling page or leaf that places uncoiler 2 (step 316 not) at it, paper alternative pack 67 is carried out paper and is selected to handle (step 320).
In paper was selected to handle, paper alternative pack 67 at first obtained all paper identifiers that are stored in the paper information memory unit 65, and the remaining sheet length (step 212) corresponding with the paper identifier.Next, paper alternative pack 67 with the ascending order of the corresponding remaining sheet length of being obtained to paper identifier classify (step 213), and with the first paper identifier, promptly the shortest paper identifier of remaining sheet length is set to first comparison object (step 214).
Then, 67 pairs of paper alternative packs be set to comparison object the paper identifier residue length with need yardage to compare.Be not less than when needing yardage in remaining sheet length (being in the step 215), paper alternative pack 67 is judged the paper identifier target (step 216) as an alternative that will be set to comparison object.
On the contrary, the result who supposes comparison is a remaining sheet length less than the conclusion that needs yardage (in the step 215 not).In this case, when having the paper identifier that is not compared as yet (being in the step 217), the next one in the paper identifier of having classified is set to comparison object (step 218).The remaining sheet length of paper identifier is compared with the needs yardage in the same manner.
The remaining sheet length of supposing all paper identifiers that are stored in the paper information memory unit 65 and the comparative result that needs yardage draw all remaining sheet length all less than the conclusion that needs yardage (in the step 217 not).In this case, when a plurality of print out task were selected as the print out task that order be about to carry out (being in the step 219), paper alternative pack 67 was carried out on demonstrations/functional unit 12 and is shown to come the requirement user to provide the print out task of reselecting execution soon or the instruction (step 220) of being replaced current paper by new paper.So when the user provides the instruction of reselecting print out task (in the step 221 not), paper alternative pack 67 turns back to step 311 and shows the print out task tabulation and wait for that the user reselects task.
When the user provides the instruction of replacing current paper by new paper (being in the step 221), or when single print out task is selected as being removed the print out task carried out by order (in the step 219 not), new paper is confirmed as replacing target (step 222).
Paper as an alternative target be when select to handle determining by paper, paper alternative pack 67 makes demonstration/functional units 12 demonstrate current paper must be replaced (step 321) by the paper identifier of paper that is defined as replacing target or new paper.
Paper is replaced (step 322) by the user to the response that shows.When paper is replaced by new paper (being in the step 323), paper information memory unit 65 is provided with paper identifier (step 324) for new paper, is provided as the default value (step 325) of its remaining sheet length, and the paper identifier that is provided with of storage and the remaining sheet length (step 326) of setting.The paper identifier can automatically generate, perhaps can be by the user by 12 inputs of demonstration/functional unit.
Then, control assembly 11 in by external equipment attaching parts 16 control uncoilers 2 and rewinding machine 3 control paper transfer member 14 and image forming part 15 to carry out print processing (step 317).When print processing finished, according to the signal from paper transfer member 14, image forming part 15 etc., remaining sheet length detection parts 64 detected the remaining sheet length (step 318) of the rolling page or leaf that is used to print.According to the remaining sheet length that detection obtains, paper information memory unit 65 upgrades the remaining sheet length (step 319) corresponding with the paper identifier of the rolling page or leaf that places uncoiler 2.So processing finishes.
