As shown in Figure 1, printer 2 receives print request from the host apparatus such as personal computer 1, it is situated between in printings such as paper PM It is printed in matter, for example, being SIDM (serial impact type dot matrix) printer (click type printer).

Printer 2 has control unit 21 and mechanism part 22, and control unit 21 is constituted as function, as shown in Figure 1, having reception Buffer 211, data store 212, printing control unit 213 and drive control part 214.It should be noted that control unit 21 It is constituted as hardware, has CPU, RAM, ROM, NVRAM, ASIC etc..

Control unit 21 is the part for controlling the whole movement of printer 2, and printing control unit 213 is responsible for printing treatment therein The control of (passing through the processing of print head 221).Specifically, explaining from the received printed data of host apparatus 1, will indicate to print The data of the object unit of object are launched into the data of a unit, control print head 221 based on the data.

In addition, drive control part 214 controls the movement of aftermentioned balladeur train 222 and paper delivering mechanism 223.Balladeur train 222 Movement speed (driving speed V) is variable, and the multiple drive mode works different with driving speed V as described later of balladeur train 222 Make.It should be noted that the selection processing by the drive mode of drive control part 214 has the characteristics that particular content is such as It is lower described.

It is based on being stored in ROM it should be noted that passing through by the processing of printing control unit 213 and drive control part 214 In the CPU or ASIC etc. of firmware (software) work execute.

Receiving buffer 211 is the interim storage data buffer of (storage) from the received printed data of host apparatus 1, by RAM etc. is constituted.

Data store 212 is the memory for the various data that memory control unit 21 uses, about the control of balladeur train 222, Store the acceleration and deceleration characteristic information (acceleration and deceleration curves) of each drive mode, drive mode determines table and drive mode selection table 215。

As described above, driving of this printer 2 about balladeur train 222, has multiple drive modes, but here, as one Example explanation has the case where 3 drive modes (Mode A, Mode B, Mode C).Mode A in the driving speed V of each mode Most fast, Mode B takes second place, and Mode C is most slow.

The acceleration and deceleration characteristic information (acceleration and deceleration curves) being stored in data store 212 be with drive distance L (it is mobile away from From) and driving speed V relationship (relative to driving distance L mark and draw driving speed V characteristic curve) performance reach each driving mould Accelerating performance until the driving speed V (maximum speed) of formula and the deceleration from driving speed V (maximum speed) until stopping Characteristic.

Fig. 2 is to instantiate the figure of acceleration and deceleration characteristic information (acceleration and deceleration curves).In fig. 2 it is shown that 3 drive modes The characteristic curve of (Mode A, Mode B, Mode C), the information for showing the curve are stored in data as acceleration and deceleration characteristic information In storage unit 212.The characteristic curve of each drive mode is to be pre-designed, and has stored in data in the use of printer 2 and deposits In storage portion 212.Drive control part 214 is with acceleration and deceleration characteristic information (the characteristic song at the moment according to selected drive mode Line) and the mode of acceleration and deceleration controls balladeur train 222.

Drive mode determines that table is for determining and corresponding to based on the print request (printed data) sent from host apparatus 1 In the table of the drive mode of the balladeur train 222 of the requirement, conclusion have printing condition and with the printing condition suitably corresponding driving The information of mode.In print request (printed data), the printing condition including press quality, but table is determined in drive mode In, the drive mode (for example, Mode C) for having selected driving speed V low when having required high-quality, when low-quality, with choosing Select the mode set information of the drive mode (for example, Mode A) of driving speed V high.It should be noted that the drive mode is true Determining table is when having received printed data, and drive control part 214 is made when determining the drive mode used in the presswork With.

Drive mode selection table 215 is that selection should (before each scanning) before the printing of each row for drive control part 214 The table of the drive mode of the most suitable balladeur train 222 of row (scanning).Fig. 3 is an example for showing drive mode selection table 215 Figure.As shown in figure 3, drive mode selection table 215 is " drive mode " that will indicate moving distance " threshold value " Yu balladeur train 222 Corresponding table (information).

" threshold value " is the value compared with aftermentioned prediction moving distance PL, and drive control part 214 is referring to the drive mode Select table 215, when predict moving distance PL > S1, select Mode A, in S1 >=prediction moving distance PL > S2, selection and The corresponding Mode B of S1 selects Mode C corresponding with S2 in S2 >=prediction moving distance PL.

It should be noted that " threshold value " meets the relationship of S1 > S2, and when selecting drive mode as described above, the threshold value The scanning for being set to the balladeur train 222 of prediction moving distance PL is completed in the shortest time.It should be noted that " threshold value " uses Acceleration and deceleration characteristic information (characteristic curve) of above-mentioned each drive mode etc. determines, is stored in advance in data store 212.

It should be noted that data store 212 is made of nonvolatile memory (NVRAM) etc..

Mechanism part 22 is worked by the control of control unit 21, is actually in the upper portion for executing printing treatment such as paper PM Point.As shown in Figure 1, mechanism part 22 has print head 221, balladeur train 222 and paper delivering mechanism 223 etc..

Print head 221 is the part that (printing) is printed on paper PM for being delivered to printing position etc., that is, point Impact type head.Have ink ribbon and multiple needles in print head 221, needle is configured across ink ribbon in the position that can strike paper PM etc. On.

Balladeur train 222 carries print head 221, in printing, along the direction (scanning direction orthogonal with the conveying direction of paper PM SD), moved along paper PM.The drive that balladeur train 222 is selected by motor not shown in the figure, transmission device with drive control part 214 Dynamic model formula is driven.

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.
