Paper delivering mechanism 223 is until the paper PM etc. as printed medium is delivered to printing position, and is printing
The mechanism of paper PM etc. is discharged from printer 2 afterwards.Paper delivering mechanism 223 has paper feed roller, exit roller, their driving electricity
Machine and transmission device and transport path etc..
In this printer 2 for having composition described above, the drive control of balladeur train 222 has the characteristics that, below to it
Particular content is illustrated.
As described above, the drive mode of balladeur train 222 has prepared multiple (to be three herein according to the difference of its driving speed V
It is a).In general, being printed compared with the case where using driving speed V slow drive mode using driving speed V fast drive mode
The brush time shortens, and the point that handling capacity improves is effective.
However, the balladeur trains such as print range P short situation 222 moving distance L in short-term, use the fast drive of driving speed V
Dynamic model formula may spend instead the time.
Fig. 4 is the figure of the relationship of the driving distance L and driving speed V when instantiating the printing for carrying out having sufficient length.
Fig. 5 is to instantiate the figure of the relationship of driving distance L and driving speed V when carrying out short printing.
In Fig. 4 and Fig. 5, horizontal axis indicates that the driving distance L of balladeur train 222, the longitudinal axis indicate the driving speed V of balladeur train 222.This
Outside, in Fig. 4 and Fig. 5, print range P indicate balladeur train 222 printed in single pass range (scanning direction SD away from
From).In addition, showing balladeur train 222 under each drive mode of Mode A and Mode B in Fig. 4 and Fig. 5, carry out respective
The relationship of driving distance L and driving speed V when the printing of print range P.
In situation shown in Fig. 4, that is, in the case that print range P has enough distances, use any driving mould
When formula, the curve to slow down, two kinds of drive modes are become thereafter with speed driving in a short time all after reaching most high speed
Under driving distance L it is roughly the same.Therefore, the sweep time (traveling time) of balladeur train 222 be the fast Mode A of driving speed V more
It is short.That is, the printing time of print range P is that Mode A is shorter.
It should be noted that in each drive mode, printing start time and printing finish time be it is predetermined, it is preceding
Person be accelerate in it is predetermined at the time of, the latter be slow down in it is predetermined at the time of.In addition, distance EL shown in Fig. 4 is printing knot
Distance (distance after hereinafter referred to as printing) until balladeur train 222 stops (after printing finish time) after beam, each drive mode is total
It is logical.
On the other hand, in the case of fig. 5, that is, in the case that print range P is short, as shown in figure 5, in Mode B
Drive mode in, printing can be executed in above-mentioned printing start time and printing finish time, with situation one shown in Fig. 4
Sample, balladeur train 222 can not drive the distance of (movement) futile effort and stop.
On the other hand, in the drive mode of Mode A, as shown in figure 5, printing, In can be terminated before reaching most high speed
Just reach most high speed to reduce speed now later, but the case where its driving distance L ratio Mode B is long very much.Therefore, in such print
When brush range P, driving speed V fast Mode A spends time (traveling time, printing time) instead.
As described above, print range P in short-term, the drive mode for having selected driving speed V low sometimes can contract
Weakness manages the time, in this printer 2, considers that the point carries out the drive control (drive mode of balladeur train 222 in the printing of each row
Selection).
Fig. 6 is to instantiate the flow chart of processing sequence when this printer 2 receives print request.Hereinafter, being docked based on Fig. 6
It is illustrated by the processing of 1 desired presswork.
When the printed data from host apparatus 1 is sent, printer 2 receives the printed data, stores (preservation) In
It receives in buffer 211 (the step S1 of Fig. 6).
Thereafter, control unit 21 (printing control unit 213, drive control part 214) reading, which is stored in, receives in buffer 211
Printed data (header) is simultaneously explained, the basic settings of printing treatment is carried out based on its result.In this process, drive control part
214 determine the drive mode (the step S2 of Fig. 6) of balladeur train 222.
Specifically, the printing condition as contained by printed data of control unit 21 is determined about text interval, length of changing one's profession, list
The content that the projects such as direction scanning or twocouese scanning are implemented.About drive mode, based on text product contained by printed data
Matter specifies to determine.When text quality is appointed as high-quality, drive control part 214 is determined slow drive mode (such as Mode
C) as the drive mode used, when text quality is appointed as low-quality, drive control part 214 is determined fast drive mode
(for example, Mode A) is as the drive mode used.
Thereafter, the printing treatment of each row (each scanning) is moved to, printer 2 carries out the drive mode for being most suitable for the row first
Selection handles (the step S3-S9 of Fig. 6).
In selection processing, from the reading of buffer 211 next line is received, (next time is printed drive control part 214 first
The row of brush) printed data (the step S3 of Fig. 6).Due to being to be somebody's turn to do in actual printing treatment (the step S10 of Fig. 6)
It is read before the reading of printed data, therefore the processing is the processing pre-read.
Then, drive control part 214 explains the printed data read, finds out and obtains and is printed in next line (scanning)
Distance (length of print range P, hereinafter referred to as printed distance L (2)) (the step S4 of Fig. 6).
Fig. 7 is the figure for illustrating the moving distance of balladeur train 222.Fig. 7 schematically shows balladeur train 222 and moves up in paper PM
Dynamic state, the current location shown in Fig. 7 of balladeur train 222 are moved along scanning direction SD, are performed simultaneously the printing of print range P.
Motion track MW shows the motion track of balladeur train 222 at this time.The above-mentioned printed distance L (2) acquired is equivalent to L shown in Fig. 7
(2)。
Then, drive control part 214 obtains the current location (the step S5 of Fig. 6) of balladeur train 222.Specifically, driving control
Portion 214 processed finds out the position of the scanning direction SD of balladeur train 222 from past moving distance etc..
Then, drive control part 214 finds out and obtains from the current location of balladeur train 222 to printing starting position (in Fig. 7
The left end of print range P) until distance (hereinafter referred to as printing front distance L (1)) (the step S6 of Fig. 6).Specifically, driving
Dynamic control unit 214 finds out printing front distance L from the current location of balladeur train 222 of above-mentioned acquisition and the printed data of above-mentioned reading
(1)。
Then, drive control part 214 find out and obtain from printing end position (right end of the print range P in Fig. 7) to
Distance (distance L (3) after hereinafter referred to as printing) (the step S7 of Fig. 6) until the stop position of balladeur train 222.Drive control part
214 use the value of above-mentioned distance EL shown in Fig. 4 as distance L (3) after the printing.The value of distance EL is stored in advance in number
According in storage unit 212 etc..
Thereafter, after drive control part 214 passes through the printing front distance L (1) that will acquire and printed distance (2) and prints away from
It is added from (3), that is, passes through the formula of PL=L (1)+L (2)+L (3), find out and obtain prediction moving distance PL (the step of Fig. 6
S8)。
Then, the most suitable drive mode (the step S9 of Fig. 6) when the selection of drive control part 214 printing next line.Specifically
For, drive control part 214 referring to the drive mode selection table 215 illustrated based on Fig. 3, compare above-mentioned acquisition prediction it is mobile away from
Each threshold value from PL and drive mode selection table 215, selects most suitable drive mode as described above.That is, drive control part
214 when predicting moving distance PL > S1, selects Mode A, in S1 >=prediction moving distance PL > S2, selects corresponding with S1
Mode B selects Mode C corresponding with S2 in S2 >=prediction moving distance PL.
It is selected in this way, has selected the drive mode for completing processing with the shortest time when printing next line.
Then, drive control part 214 compares sets in the most suitable drive mode (the second drive mode) and step S2 of selection
Fixed drive mode (drive mode, the first drive mode when printing starts), if the drive of the most suitable drive mode of selection
If the driving speed V of dynamic drive mode of the speed V than setting in step S2 is slow, determination switches to the most suitable drive mode,
Carry out the printing of next line.That is, drive control part 214 reduces driving speed V in the printing of next line.On the other hand, it is elected to
When the driving speed V for the most suitable drive mode selected is the driving speed V or more of the drive mode set in step S2, driving control
Portion 214 processed, which determines, does not switch to the printing that the most suitable drive mode carries out next line.That is, drive control part 214 is still with print
Drive mode when brush starts carries out the printing of next line.
It should be noted that due to when the drive mode drive mode of printing while starting () set in step s 2 is most
When the lower drive mode of the driving speeds such as low velocity V, the drive mode is not available selecting most suitable drive mode yet,
Or the case where not using, is more, therefore can also handle (step S3-S9) without the selection.For example, when starting in printing
When be set to when Mode C (step S2), in the processing of each row, it is convenient to omit selection handle (step S3-S9).
In this way, executing the printing treatment (the step S10 of Fig. 6) of next line when the drive mode used has been determined.At this
In printing treatment, printing control unit 213 reads and explains the printed data from the current line for receiving buffer, by printing object
It is launched into point data.Thereafter, printing control unit 213 makes print head 221 work by the point data.Drive control part 214 with
The printing acts corresponding mode, controls paper delivering mechanism 223, conveys paper PM along sub-scanning direction, with print head
The synchronous mode of 221 movement drives balladeur train 222 with the drive mode of above-mentioned determination.
In this way, executing same processing (the step S3-S11 of Fig. 6) to each row, directly when processing terminate for the amount of a line
Until processing terminate for received whole printed data (full row) (the step S11's of Fig. 6 is no).Moreover, working as received whole
Printed data (full row) when processing terminate (the step S11's of Fig. 6 be), processing terminate for the one-step print operation.
It should be noted that being next when the printing of a line terminates position (scanning direction SD's) that balladeur train 222 stops
In the range of the scanning direction SD of capable print range P, and near its range and enough run-up distances can not be obtained
When, it needs to make balladeur train 222 mobile before printing next time.Therefore, when pre-reading printed data in the step S3 of Fig. 6, under
The printed data of a line reads and explains again simultaneously the printed data of next line (downlink), at the end of the printing of next line on
The state stated, in the case where becoming the state for needing to make before printing balladeur train 222 mobile, after the printing of next line,
Stop at once balladeur train 222, but moves it to the position that can get enough run-up distances in the printing of downlink
Until stop.At this point, distance L (3) is not predetermined distance EL after printing in the step S7 of Fig. 6, it is actually to stop it
Distance until only.It carries out in this way, the processing (saving secondary movement) for moving balladeur train 222 before printing can be saved, together
When, even if being also able to extend prediction in the case where the print range P of next line shortens and reduces drive mode (driving speed V)
Moving distance PL does not make drive mode reduce and handle with faster driving speed V.
In addition, illustrating have the case where three drive modes, but the quantity of drive mode in above embodiment example
It is also possible to quantity in addition to this.When the drive mode having is multiple, the drive that is set in drive mode selection table 215
Dynamic model formula is not the drive mode of all of which, and is omitted the drive mode of some quantity.For example, having 15 drives
, can be according to 5 drive modes of the sequential selection of their driving speed V under substantially uniform interval when dynamic model formula, it will
This 5 drive modes are set in drive mode selection table 215.In this case, drive mode selection table 215 is had references to
Above-mentioned selection processing similarly carry out.
It should be noted that having selected place in the selection processing (the step S9 of Fig. 6) of above-mentioned most suitable drive mode
Managing the time becomes shortest most suitable drive mode, but (waits in the modifiable mode for shortening the drive mode of processing time
Mend) when having multiple, it also can choose and drop next grade of driving since the drive mode (drive mode when printing starts) of setting
Mode etc. selects the drive mode other than most suitable drive mode.For example, when being set to Mode A, the printing of next line
Range P shortens, and when Mode C is most suitable, can choose Mode B.
As described above, in the printer 2 that present embodiment example is related to, before the printing of each row, based on balladeur train 222
The printed data of current location and next line finds out the prediction moving distance PL of balladeur train 222, and is based on prediction moving distance PL
Select most suitable drive mode.It therefore, is that fast driving mode is spent instead in driving speeds V such as the short situations of printing length
In the case where time, driving speed can be suitably reduced, and the printing treatment time can be shortened.In turn, it does not need to increase
Unit scale increases using electric power, and cost will not be made to increase.
Further, since the switching of above-mentioned drive mode be with the requirement as press quality etc. set by compared with drive mode
And it executes, therefore the printing for being unsatisfactory for print request can be prevented.
In addition, when the drive mode set when printing and starting is specified driving speed V or less, by without above-mentioned
The selection of most suitable drive mode is handled, and can save futile processing.
In addition, the selection processing of above-mentioned most suitable drive mode is fast by referring to preset drive mode selection table
It carries out fastly.
In addition, as described above, by the candidate for reducing drive mode there are it is multiple when, select close to set driving
The difference of printing state with other rows can be inhibited smaller by the drive mode of mode.
Protection scope of the present invention is not limited to above-mentioned embodiment, the invention including being recorded in the scope of the claims and
It is equally invented.
