Abstract
The invention provides a method for controlling a printer and, a printer wherein a movement amount of a carriage is shortened as much as possible for shortening a printing time, and at the same time, an ink ribbon is surely taken up even when a printing region of one line is short. From a carriage movement start position to an ink ribbon take-up start position where speed reducing gears 21 drive thereby actually taking up the ink ribbon 10a is set as an ink ribbon non take-up region. Before the carriage 6 starts moving, it is judged whether or not the movement amount of the carriage 6 required for printing one line exceeds the ink ribbon non take-up region. When the movement amount does not exceed the region, a slow down region of the carriage 6 is increased until the movement amount exceeds the ink ribbon non take-up region.
Description
Technical field
The present invention relates to print the printer of pattern, especially about the coiling control technology of colour band with colour band.
Background technology
This printer be contained on the balladeur train printhead to be clipped in and paper bobbin between printing paper with a plurality of line point forms to the colour band that rolls out from ribbon cartridge is got ready, measuring point is rectangular printing curve.Printhead moves around along colour band by balladeur train, by the mobile print delegation that comes or return with send alternately perseveration of delegation's paper.At the printer of this pattern, usually, make the mobile interlock of the coiling and the balladeur train of colour band.To this, for example the colour band wireline reel that balladeur train moves with timing belt and ribbon cartridge is connected with train of reduction gears.At this moment, in train of reduction gears, no matter balladeur train comes or return switch means such as clutch gear is set in one direction to make colour band to reel.In addition, be to shorten the time-write interval, carry out the MIN sledge drive that can print, finish the control of minimizing balladeur train amount of movement according to print span.
In fact balladeur train is controlled so as to certain speed in the print area of printing and moves delegation, before and after it, sets acceleration (slow-up) zone and (slow-down) zone of slowing down mostly for.Acceleration region is for from beginning to move to the distance of quickening till the print area, the zone of slowing down for the print area end after to the distance of the deceleration that stops.And, be purpose to shorten total time-write interval, wish that these fields can set narrowlyer as far as possible.
Yet, colour band batch can not with the beginning to move and begin simultaneously of balladeur train.There is backlash (space between the flank of tooth) in the mobile train of reduction gears that reaches the colour band wireline reel of tool main cause balladeur train.Fig. 8 represents mobile (line of below) of balladeur train and follows the relation of its colour band reeling condition (line of top).As shown in the drawing, play the colour band wrapping range that actual colour band reeled from the beginning shift position of balladeur train till, exist with the train of reduction gears engagement and begin to move the zone that the corresponding colour band of delay of this section period do not reel.Balladeur train quickens, and in the way that has entered print area, has in fact entered the colour band wrapping range of the colour band of reeling, and finish in the zone of slowing down, and balladeur train just stops, and the coiling of colour band also stops simultaneously.
On the printer of setting like this, if owing to the print span of reason delegation such as number of words is few is extremely narrow, as shown in Figure 9, can by colour band not before the wrapping range deceleration zone just be through with, the coiling of also not finishing colour band sometimes just finishes the printing of delegation.And the continuous multirow that if colour band is not reeled, print span is narrow, like this, because the line point of printhead is always got ready at the same position of the colour band of not reeling, printing ink will be not enough, produces the thin out gradually incorrect phenomenon of printing writing.
Summary of the invention
Print thin out means as suppressing this type of, the method for expecting is that the speed reducing ratio that reduces train of reduction gears shortens not wrapping range of colour band.But if these means of employing, the load that drives the motor of balladeur train just increases, and just needs jumbo motor for addressing this problem.Particularly on fixed ribbon cartridge, because the coiling load of the just big colour band of box body itself is also big.And too small if speed reducing ratio obtains, then the translational speed of winding speed and balladeur train is just approaching, and the same place that will be created in colour band is sometimes got ready and the incorrect phenomenon of printing ink deficiency.As other means, also can consider will speed up zone and deceleration zone and set for the same longly, but described total time-write interval is shortened, again because acceleration region and the regional usefulness of deceleration the dead zone be necessary, so, also can the outer big problem of deformation of generation device.
Therefore, the object of the present invention is to provide a kind of control method and printer of printer, it can be in order to shorten the amount of movement that the time-write interval reduces balladeur train as much as possible, even also can carry out the coiling of colour band in the quite short occasion of the print area of 1 row infalliblely.
Its printer of the control method of printer of the present invention possesses: ribbon cartridge, printhead with the colour band subtend configuration that rolls out from this ribbon cartridge, the balladeur train of this printhead is housed, the carriage driving mechanism that printhead is moved with balladeur train along colour band, move the colour band winding mechanism of interlock coiling colour band with balladeur train, and supply printhead prints data, and the control part that carriage driving mechanism is moved, this method moves the starting position with the balladeur train that moves, and to play the colour band winding start position fastening that ribbon spool really reeled around the mechanism action colour band be not wrapping range of colour band, before balladeur train begins to move, judge whether print the required balladeur train amount of movement of 1 row has surmounted not wrapping range of colour band, when not surmounting, increase the balladeur train amount of movement up to running off colour band not till the wrapping range.
Adopt above-mentioned control method, before balladeur train moves, precompute and print the required balladeur train amount of movement of 1 row, judge whether this amount of movement runs off not wrapping range of colour band.Then, do not exceed colour band not during wrapping range,, the amount of movement of balladeur train is increased up to surmounting colour band not till the wrapping range promptly only in the extremely narrow occasion of print area (print span) at the balladeur train amount of movement.Balladeur train one runs off not wrapping range of colour band, and the colour band winding mechanism is action just, therefore, even also can reel infalliblely at the extremely narrow occasion colour band of print area.Its result, very narrow even several provisional capitals of ining succession are print spans, printhead is still always beaten on new colour band, can not produce print thin out.On the other hand, the balladeur train amount of movement runs off colour band not during wrapping range, according to run off part apart from ribbon spool around mechanism action, the colour band of reeling.According to above-mentioned control, can reduce the balladeur train amount of movement in order to shorten the time-write interval as far as possible, and, even, also can batch colour band infalliblely in the occasion that is rather narrow of print area of 1 row.
In addition, printer of the present invention is for being suitable for implementing the printer of above-mentioned control method, this printer possesses: ribbon cartridge, with the printhead of the colour band subtend that rolls out from this ribbon cartridge configuration, be equipped with this printhead balladeur train, along described colour band make carriage driving mechanism that described printhead and described balladeur train move, with described balladeur train move interlock coiling colour band the colour band winding mechanism, and supply with the printhead prints data, and make the control part of carriage driving mechanism action; Described control part comprises: as the interface of master computer input part; To move the ROM that write down to the balladeur train amount of movement of ribbon spool around mechanism action, till making the colour band winding start position of the actual colour band of reeling the starting position from the balladeur train that described balladeur train moves beginning; The RAM of storaging printing data as required; Calculate by described print data and to print the required balladeur train amount of movement of 1 row and compare, print the CPU that amount of movement that the required balladeur train amount of movement of 1 row hour makes balladeur train increases by an ormal weight judging with the balladeur train amount of movement of described ROM record.

The specific embodiment
Below, with reference to a description of drawings example of the present invention.
Fig. 1 represents to relate to the general illustration of the printer 1 of this example, and symbol 2 is a machine frame for casing, 3a, 3b in the figure.Balladeur train guide rod 4 supported by machine frame 3a, 3b, and along this balladeur train guide rod 4, the balladeur train that printhead 5 is housed is 6 supported, can back and forth move freely.Balladeur train 6 is fixed on a section of being disposed at its below and is with synchronously on 7, follows synchronously with 7 move around and also can move around.Be wound on follow-up pulley 8 and the not shown drive pulley with 7 synchronously, drive balladeur train 6 by the sledge drive motor 41 (with reference to Fig. 5) that makes the drive pulley rotation.It is the carriage driving mechanism of this moment with 7 synchronously that sledge drive motor 41 reaches.
Fig. 2 is the expression carriage driving mechanism and the vertical view of major part on every side thereof, also as shown in Figure 2: on machine frame 3a, 3b to support the platen 9 parallel freely with balladeur train guide rod 4 with the state rotation of printhead 5 subtends.Regulation position loading and unloading on machine frame 3a, 3b are installed with the fixed ribbon cartridge 10 that possesses colour band 10a freely.Colour band 10a rolls out from ribbon cartridge 10 interior circulations, rolls out part and holds under the arm between printhead 5 and platen 9.
5 pairs of the printheads of printer 1 are held printing paper not shown between platen 9 under the arm and in the mode of a plurality of line points colour band 10a are got ready, the print pattern that measuring point is rectangular.Printhead 5 moves around along colour band 10a by balladeur train 6, goes, send 1 row paper such alternate repetition action by the mobile print 1 that comes or return.Paper feeding is finished with the paper advance mechanism of motor by possessing not shown paper feeding.Also have, in this occasion, balladeur train 6 is fixed among Fig. 2 synchronously on the straight line position with sides above 7.
The colour band 10a of ribbon cartridge 10 becomes and can reel with the mobile interlock of balladeur train 6, with reference to Fig. 3 and Fig. 4 this mechanism is described.As shown in Figure 3, driven wheel 11 and support are arranged to one with 7 follow-up pulley 8 synchronously.On the other hand, as shown in Figure 4, insert in ribbon cartridge 10 colour band 10a is wound on colour band wireline reel 12 ribbon cartridge 10 in, driven wheel 11 and colour band wireline reel 12 are by being configured in train of reduction gears (colour band winding mechanism) 21 connections on the gear plate 20.12 rotations of colour band wireline reel are supported on the gear plate 20 freely.
As shown in Figure 3, the oval clutch plate 23 supported freely by gear plate 20 rotations by clutch gear 22, an end of train of reduction gears 21, constitute by the other end support of clutch plate 23 and with the idler gear 25,26,27 of clutch gear 22 planet gear meshed the 24, the 1st, the 2nd and the 3rd and the ribbon cartridge gear 28 that is fixed on colour band wireline reel 12 lower ends.
Clutch gear 22 and clutch plate 23 shared axles are with driven wheel 11 engagements.Planetary gear 24 is by the distolateral support of the rotation of clutch plate 23.The the 1st～the 3rd gear 25～27 is supported by gear plate 20.The the 1st and the 2nd gear 25,26 is for having two sections gears of gear wheel 25a, 26a and pinion 25a, 25b respectively, be configured in the both sides of planetary gear 24, planetary gear 24 is according to the rotation of clutch plate 23, with any gear wheel 25a (26a) engagement of the 1st gear 25 and the 2nd gear 26.Then, the pinion 25b of the 1st gear 25 and 28 engagements of ribbon cartridge gear, in addition, the pinion 26b of the 2nd gear 26 connects with ribbon cartridge gear 28 by the 3rd gear 27.
When synchronously with 7 to the solid arrow A of Fig. 3 direction action make balladeur train 6 when move on the left side of Fig. 3 and the driven wheel 11 of follow-up pulley 8 one to rotation counterclockwise.Corresponding, at first clutch plate 23 is to the clockwise direction rotation of Fig. 3, and then, the gear wheel 25a of planetary gear 24 and the 1st gear 25 meshes.Under this state, the rotation of driven wheel 11 reaches ribbon cartridge gear 28 through clutch gear 22, planetary gear the 24, the 1st gear 25, and just to the counter clockwise direction rotation of Fig. 3, colour band 10a just is wound in the ribbon cartridge 10 ribbon cartridge wireline reel 12.
On the other hand, when making balladeur train when the right of Fig. 3 is mobile with the 7 direction actions to the dotted arrow B of Fig. 3 synchronously, driven wheel 11 just rotates to clockwise direction.So clutch plate 23 just rotates the gear wheel 26a engagement of planetary gear 24 and the 2nd gear 26 to the counter clockwise direction of Fig. 3.The rotation of driven wheel 11 reaches ribbon cartridge gear 28 through clutch gear 22, planetary gear the 24, the 2nd gear the 26, the 3rd gear 27 under this state.Thus, still to the counter clockwise direction rotation of Fig. 3, colour band 10a is wound in the ribbon cartridge 10 colour band wireline reel 12.Promptly, corresponding with the switching of balladeur train 6 moving directions, along with the rotation of clutch 23, switch the driving bang path that leads to ribbon cartridge gear 28, no matter balladeur train 6 can both be in (on the direction of coiling colour band 10a) rotation on the certain orientation to mobile colour band wireline reel 12 to which side.
The switching of above-mentioned driving bang path occur in make at the balladeur train 6 that is moving towards a direction stop, balladeur train 6 begins to move on opposite direction with that.But, owing to there is the running clearance of backlash and clutch plate 23 between each gear of train of reduction gears 21.Thereby balladeur train 6 begins to move back to colour band wireline reel 12 and really begins to have very of short duration time delay till the rotation.The beginning shift position when the balladeur train 6 conversion moving directions is just moved to balladeur train 6 and to be made train of reduction gears 21 be coupled situation to end, and the colour band that exists the colour band 10a that can not reel is wrapping range not.
The block diagram that Fig. 5 constitutes for expression printer 1.Printer 1 is the control part 30 control printer actions (printing and transmit print paper) that CPU (balladeur train amount of movement comparing section, balladeur train amount of movement control part) 30a, interface 30b, ROM30c and RAM30d constitute by the microcontroller of built-in various peripheral functions.Interface 30b is the input and output portion to main frame 31.In addition, storage control program, fixed data among the ROM30c, RAM30d is storaging printing data etc. on demand.These interfaces 30b, ROM30c and RAM30d are connected with CPU30a.CPU30a is according to existing the program among the ROM30c to carry out various controls.CPU30a will drive signal according to print data and supply with printhead 5, actuating signal be supplied with paper feeding motor 40 and sledge drive motor 41 again.
The CPU30a of control part 30 supplies with actuating signal to sledge drive motor 41 makes balladeur train 6 do following moving.At first, ROM30c storage from the mobile starting position of balladeur train 6 to and the colour band step number of the pairing carriage motor 41 of distance of wrapping range not the colour band 10a of in fact reeling.CPU30a prints 1 row and before balladeur train 6 begins to move at need, the amount of movement of calculating the required balladeur train 6 of this 1 line printing in advance be sledge drive motor 41 step number simultaneously, with this step number and colour band not the step number of wrapping range make comparisons.Then, whether the CPU30a judgement step number corresponding with the amount of movement of printing the required balladeur train 6 of 1 row surpasses the not step number of wrapping range of colour band, when surpassing, then only allows sledge drive motor 41 rotate these step numbers.In addition, be no more than colour band not during the step number of wrapping range printing the required step number of 1 row, the step number of crossing colour band and do not increase after the wrapping range again the zone of slowing down makes balladeur train 6 move the distance of regulation.
The concrete example of above-mentioned control method is described with reference to Fig. 6.
Colour band is the distance of wrapping range i.e. 264 steps of revolution of at this moment being converted into sledge drive motor 41 not.In addition, balladeur train 6 all set for 66 steps for to the acceleration of print area and the deceleration that stops to the print area end.Have, 1 of sledge drive motor 41 is about 0.1～0.2mm when going on foot the amount of movement that is converted into balladeur train 6 again.Earlier to surpass for 264 steps deny to be no more than and then to enter step S2 to balladeur train amount of movement that will print line below step S1 judges.Make sledge drive motor 66 steps of 41 rotations at step S2, quicken, then begin real printing at step S3.Just enter step S4 after printing end, make the sledge drive motor 41 Rotate 180s step, slow down, allow the sledge drive motor stop.Use said method, finish 1 line printing and finish the coiling of colour band 10a.
Fig. 7 represents the reeling condition of moving of balladeur train 6 that step S1～step S4 produces and colour band 10a, by increasing the distance in zone of slowing down, thereby makes balladeur train 6 run off colour band not wrapping range and mobile predetermined distance.Balladeur train 6 enters the colour band wrapping range in the way in zone of slowing down, after this carry out the coiling action of colour band 10a till balladeur train 6 stops.
On the other hand, in the S1 of Fig. 6 step, the balladeur train of judging the following row that will print moves and importantly exceeded for 264 steps and just enter step S5, makes sledge drive motor 41 rotate 66 and goes on foot, and quickens.Then, carry out real printing, enter step S7 after print finishing, make 41 rotations 66 of sledge drive motor, slow down, make sledge drive motor 41 stop, finishing 1 line printing and finish the coiling of colour band 10a at step S6.Carry out action shown in Figure 8 according to step S1～S7.
As mentioned above, its key of control method that relates to the printer 1 of this example is on this point: at the amount of movement of balladeur train 6 within colour band not during wrapping range, promptly only when print area (print span) is very narrow, the displacement that increases balladeur train 6 is until running off not wrapping range of colour band.In a single day balladeur train 6 runs off not wrapping range of colour band, and train of reduction gears 21 will substantially be moved, therefore, in the very narrow occasion of print area, colour band 10a also can infallible floor-covering roll around.Although the narrow continuous multirow of row of print span consequently, always printhead 5 is still beaten on the colour band 10a that refreshes, printing can be not thin out.On the other hand, run off colour band not during wrapping range at the amount of movement of balladeur train 6, corresponding train of reduction gears 21 actions, the coiling colour band 10a made from the distance that runs off part.By above control, in order to shorten the time-write interval, can shorten acceleration region and the zone of slowing down, and even when the print area of 1 row is very narrow, colour band 10a can reel infalliblely also as far as possible.
Have, at above-mentioned example, increase the displacement of balladeur train 6 by the step number that is increased in the sledge drive motor 41 in the zone of slowing down, replacing also to increase the step number of print area.Adopt this control to shorten total time-write interval more.
The as above explanation of being done, adopt the present invention and whether run off not wrapping range of colour band because judge the amount of movement of printing the required balladeur train of 1 row, only within the time increase balladeur train amount of movement up to running off colour band not till the wrapping range, so, in order to shorten the amount of movement that the time-write interval reduces balladeur train as far as possible, and obtain when the print area of 1 row is narrower the effect that colour band still can be reeled infalliblely.
