Description

Tape deck, method of transporting recording medium, liquid injection apparatus

Technical field

The present invention relates to a kind of nozzle opening row of having, possess executive logging in being recorded material record head, will be recorded material be sent to relative with this record head to the transfer roller of position and tape deck, method of transporting recording medium and the liquid injection apparatus of control part that the action that the record of each action of being used to comprise above-mentioned record head and transfer roller is carried out is controlled.

Background technology

Here, liquid injection apparatus not only is meant from the record head as fluid jetting head and is recorded the material ink-jet to record-paper etc., carry out tape decks such as inkjet recording device, duplicator and facsimile machine to the record that is recorded material, comprise that also the liquid with corresponding special-purpose replaces ink-jet, from being equivalent to the fluid jetting head of above-mentioned record head, to the injected medium injection that is equivalent to be recorded material, allow liquid attached to the device on the injected medium.

In addition, fluid jetting head except above-mentioned record head, employed living body organic matter shower nozzle and as the test portion shower nozzle of the injection test portion of accurate suction pipe (pipette) etc. in employed electrode material (conductive slurry) shower nozzle, the biochip manufacturing during employed color material shower nozzle, OLED display or face active display (FED) electrode of etc.ing formed during the colour filter (color filter) that can also list LCD etc. was made.

With the ink-jet recording apparatus is example, to former describing with the paper transfer approach.Be layered in the record-paper in the carton, be sent to afterwards, be sent on the platen of facing mutually with record head (flaten) by transfer roller as the back guider (guide) of transfer path by paper feed roller.At this moment, the sensor that is arranged on the record head detects record-paper, by control part control the front end of record-paper is stopped on the record start position.At this moment, about the logging mode of front end blank, for example by non-flanged logging mode, blank 3mm pattern, blank 5mm pattern, it is different that record start position is separately set ground.In other words, by logging mode, make record-paper in position difference that platform stops.In the following description, the stop position of establishing the record-paper of non-flanged logging mode is P1, and the stop position of the record-paper of blank 3mm pattern is P2, and the record-paper stop position of blank 5mm pattern is P3.

Transfer rate when next, record-paper being stopped in record start position describes.

Shown in Figure 17 is the expression curve map that record-paper is sent to the relation of the speed of record start position and distance of the prior art.The longitudinal axis of curve map represents to drive the speed that transmits with the drive motor of driven roller.In addition, transverse axis is represented step (step) number of drive motor, also is the distance of the record-paper that transmitted.At first, be in the drive motor starting of halted state, accelerate to certain speed V1.Afterwards, transmission transmits with certain speed V1 ' record-paper with driven roller to direction of transfer.

Next, sensor detects the front end of record-paper.This is " sensor detection " on the curve map.Next, detect the front end of record-paper, by like this, control part is in order to allow record-paper stop at arbitrary place of stop position P1～P3, and with the speed of certain negative following deceleration motor of acceleration, it stopped.Shown in Figure 17 A is record-paper in the non-flanged logging mode curve map when stopping at stop position P1.Equally, shown in Figure 17 B is in the blank 3mm pattern, and shown in Figure 17 C is in the blank 5mm pattern, the curve map when stopping at stop position P2, P3 respectively.

In order to allow the drive motor that drives with certain speed stop, and need to slow down.Like this, begin to stopping from deceleration, the step number of necessary motor is decided by the level of the certain speed before slowing down.

Therefore, in the past in order to improve disposal ability (throughput), according to from the sensor detection position to counter the pushing away of distance (step number) the shortest stop position P1, the speed of decision certain speed V1.Afterwards, constitute variation, increase control, allow record-paper stop at (for example patent documentation 1) on each stop position by the step number that the certain speed V1 after detecting with sensor is driven corresponding to stop position.

But, in the former prior art (patent documentation 1),,, therefore fully do not improve disposal ability all by identical speed transfer sheet no matter whether stop position is different.Particularly under the situation about stopping among stop position P2, the P3 beyond the nearest stop position P1 in range sensor detection position, the raising of disposal ability is insufficient.

In addition, in the latter's the prior art (patent documentation 2), because it is variable with the paper transfer rate, though therefore can expect the raising effect of disposal ability, but because according to the speed that transmits with paper with the blank value decision in paper upper end, with the speed transmission paper that this was determined, when detecting the front end of using paper by the sensor, above-mentioned motor slows down, therefore used the paper transfer rate as what determine, when the sensor detects the front end of using paper, the deceleration of above-mentioned motor must can be begun.

Therefore, under the situation of the decision of using the paper transfer rate by calculating, exist the tables of data that is used to calculate to maximize, calculate also complicated problem.

In addition, in order to begin the deceleration of above-mentioned motor when the front end that detects by sensor with paper, the position of sensor is not arbitrarily with relation with the stop position of paper, but a kind of absolute condition, therefore the setting that has been subjected to sensor in design is limited in the interior restriction of narrow scope, has the problem of the free degree decline of design.

In addition, if serve as to trigger to get started the deceleration of motor,, there is this problem of stop position precise decreasing with paper just be subjected to the influence (time lag etc.) of transducer sensitivity easily with the sensor detection.

[embodiment 1]

Contrast aforesaid Fig. 4 and Fig. 5 to Fig. 7, the embodiment 1 of relative recording device of the present invention is described.In the relative recording device of Fig. 5 for expression embodiments of the invention 1, record-paper is sent to the curve map of the speed and the relation between the distance of record start position (stop position), Fig. 6 is the frame assumption diagram of this tape deck, and Fig. 7 is in this tape deck being sent to record-paper the flow chart of the record-paper transfer approach of each record start position.Wherein, Fig. 5 A is that record-paper stops at the curve map under the situation of stop position P3, and Fig. 5 B is the situation that stops at stop position P2, and Fig. 5 C is the situation that stops at stop position P1.In addition, the longitudinal axis of curve map represents that the speed of drive motor, transverse axis represents the step number of drive motor, also is the distance of transfer sheet.

Here, drive motor (not shown) is meant the motor of the transmission driven roller 19a that drives transfer roller 19.Therefore, the rotary speed of drive motor is unique corresponding with the rotary speed of transfer roller 19.

In the present embodiment, drive motor also is the speed level of transfer roller 19, is sequentially with high speed V3, middling speed V2, these 3 patterns of low speed V1 as the rotating speed in the certain speed zone according to speed (height).Negative acceleration when acceleration when in addition, drive motor quickens and deceleration is constant.Therefore, from drive motor also be transfer roller 19 with certain speed be rotated, the state of transfer sheet P, the distance that is transmitted between the moderating process that stops after reducing speed now can be calculated according to the negative acceleration and the preceding above-mentioned certain speed that slows down.

And then above-mentioned certain speed, the distance that is transmitted in the moderating process that stops from reducing speed now to is " the 2nd distance " among the present invention.In the present embodiment, drive motor also is the speed level of transfer roller 19, be provided with 3 (V3, V2, V1) as previously mentioned, after motor drives with high speed V3, the distance that is transmitted stopping from reducing speed now to is the 2nd apart from M3 (Fig. 5 A), and after motor drove with middling speed V2, the distance that is transmitted stopping from reducing speed now to was the 2nd apart from M2 (Fig. 5 B), after motor drove with low speed V1, the distance that is transmitted stopping from reducing speed now to was the 2nd apart from M1 (Fig. 5 C).

As shown in Figure 6, control part 80 in the present embodiment, blank about record-paper P front end has 3 logging modes " non-flanged logging mode ", " blank 3mm pattern " and " blank 5mm pattern ", has above-mentioned " the 1st distance (L1, L2, L3) " about the information of record start position P1, P2 different in each logging mode, P3 simultaneously as form 1.

In addition, has information (high speed V3, middling speed V2, low speed V1) as form 3 about above-mentioned 3 speed levels of transfer roller 19, and above-mentioned " the 2nd distance (M3, M2, M1) " with the transmitting range in the moderating process of corresponding each speed level (V3, V2, V1) is as form 2.

Also have, control part 80, has optimum velocity in conveying selection mechanism 80b, if any in the selection logging mode, just will be corresponding with it " the 1st distance ", with compare according to the temporary transient speed level of selecting of the order of defined corresponding " the 2nd distance ", be shorter than in " the 2nd distance " under the condition of " the 1st distance ", select the fastest speed level in above-mentioned 3 speed levels (V3, V2, V1) of above-mentioned transfer roller 19.In the present embodiment, above-mentioned optimum velocity in conveying selection mechanism 80b, in 3 speed levels (V3, V2, V1), (M3 → M2 → M1) compare selects this speed level to the higher order of speed level when meeting above-mentioned condition in turn with above-mentioned " the 1st distance " with above-mentioned " the 2nd distance ".

In addition, control part 80 has the calculating part 80c that calculates the constant speed transmitting range.This calculating part 80c, front end at the record-paper that is transmitted by above-mentioned transfer roller 19 with the rotation of the certain speed of the selected speed level of above-mentioned optimum velocity in conveying selection mechanism 80b, be recorded after material sensors 14 detects by above-mentioned, calculate maintenance with the distance that the certain speed constant speed transmits, the difference of obtaining " the 1st distance " and " the 2nd distance " is as this constant speed transmitting range.

Next, the effect to embodiment 1 describes.Select any logging mode in " non-flanged logging mode ", " blank 3mm pattern ", " the blank 5mm pattern " by the user by not shown selection mechanism (known selector switch etc.), with this recording mode selection information, send to control part 80 as shown in Figure 6.

In the control part 80, as shown in Figure 7, select any in 3 logging modes, by any corresponding " the 1st distance (any among L1～L3) " (step 201 below is called S201) of such decision and record start position (stop position) P1, P2, P3.

Next, control part 80 compares (S202) with " the 1st distance (any of L1～L3) " with corresponding high speed V3 " the 2nd apart from the M3 " that begin to be transmitted from deceleration to the moderating process that stops.Afterwards, judging that " the 1st distance (any of L1～L3) " side is longer than " the 2nd apart from M3 ", or under " the 1st distance (any of L1～L3) " situation identical, by optimum velocity in conveying selection mechanism 80b selection speed level V3 (S203) with " the 2nd apart from M3 ".

For example, selected the user under the situation of " blank 5mm pattern ", the front end stop position of record-paper P is P3.Therefore, decision " the 1st distance L 3 " (S201).Next, optimum velocity in conveying selection mechanism 80b compares " the 1st distance L 3 " with " the 2nd apart from M3 ".If judge " the 1st distance L 3 ", just, select speed level V3 (at a high speed) (S203) as SPD=speed V3 than " the 2nd apart from M3 " long (S202).In addition, judging that the 1st distance L 3 under the identical situation (S202), also selects speed level V3 (at a high speed) (S203) apart from M3 with the 2nd.

Afterwards, shown in Fig. 5 A, also be the speed of transfer roller 19 with drive motor, accelerate to selected speed V3 (at a high speed) with certain acceleration, keep certain speed V3 (at a high speed) afterwards, with certain transfer rate V3 ' transfer sheet P (S207).

In the process of transfer roller 19 certain transfer rate V3 ' transfer sheet P with this, calculating part 80c obtains the difference (L3-M3) that " the 1st distance L 3 " deducts " the 2nd apart from M3 ", as constant speed transmitting range (S208).In addition, this constant speed transmitting range can also be obtained before transfer roller 19 begins with certain transfer rate V3 ' to transmit.

Next, in case be recorded the front end that material sensors 14 detects the record-paper P that is transmitted, just detected signal is sent to control part 80 (S209).Afterwards, allow drive motor continue to be equivalent to the step number part of above-mentioned constant speed transmitting range (L3-M3), continue constant speed and transmit (S209) with certain speed V3 (at a high speed) rotation.Afterwards, enter moderating process and reduce speed now, stop at and make the front end of record-paper P be positioned at stop position P3 place (S209).

In addition, the 1st distance L 3 with the 2nd apart from M3 under the identical situation (L3-M3=0), the result is when being recorded the front end that material sensors 14 detects record-paper P, reduce speed now, stop at and make the front end of record-paper P be positioned at stop position P3 place, if but as present embodiment, will be recorded the upstream-side-end that material sensors 14 is arranged on record head 13, could not be L3-M3=0 just usually.In addition, preferably design like this.This pass ties up between L2 described later and the M2, between L1 and the M1 too.

In addition, selected the user under the situation of " blank 3mm pattern ", the front end stop position of record-paper P is P2.Therefore, decision " the 1st distance L 2 " (S201).Next, optimum velocity in conveying selection mechanism 80b compares " the 1st distance L 2 " in step 202 with " the 2nd apart from M3 ".Can learn that from Fig. 5 A and B optimum velocity in conveying selection mechanism 80b judges that " the 1st distance L 2 " is shorter than " the 2nd apart from M3 ", enters step 204.

Optimum velocity in conveying selection mechanism 80b with " the 1st distance L 2 " with compare corresponding to " the 2nd apart from the M2 " of the slow speed V2 (middling speed) of specific rate V3 (at a high speed).Like this, if optimum velocity in conveying selection mechanism 80b judgement " the 1st distance L 2 " is longer than " the 2nd apart from M2 " (S204),, be made as SPD=speed V2 (S205) just select speed level V2 (middling speed).In addition, judging under " the 1st distance L 2 " situation identical (S204), also select speed level V2 (middling speed) (S205) with " the 2nd apart from M2 ".

Like this, shown in Fig. 5 B, also be the speed of transfer roller 19 with drive motor, accelerate to selected speed V2 (middling speed) with certain acceleration, keep certain speed V2 (middling speed) afterwards, with certain transfer rate V2 ' transfer sheet P (S207).

In the process of transfer roller 19 with this certain transfer rate V2 ' transfer sheet P, calculating part 80c obtains the difference (L2-M2) that " the 1st distance L 2 " deducts " the 2nd apart from M2 ", as constant speed transmitting range (S208).In addition, this constant speed transmitting range can also be obtained before transfer roller 19 begins with certain transfer rate V2 ' to transmit.

Next, in case be recorded the front end that material sensors 14 detects the record-paper P that is transmitted, just detected signal is sent to control part 80 (S209).Afterwards, allow drive motor continue to be equivalent to the step number part of above-mentioned constant speed transmitting range (L2-M2), continue constant speed and transmit (S209) with certain speed V2 (middling speed) rotation.Afterwards, enter moderating process and reduce speed now, and stop at and make the front end of record-paper P be positioned at stop position P2 place (S209).

In addition, selected the user under the situation of " non-flanged logging mode ", the front end stop position of record-paper P is P1.Therefore, decision " the 1st distance L 1 " (S201).Next, optimum velocity in conveying selection mechanism 80b compares " the 1st distance L 1 " in step 202 with " the 2nd apart from M3 ".Can learn that from Fig. 5 A and Fig. 5 C optimum velocity in conveying selection mechanism 80b judges that " the 1st distance L 1 " is shorter than " the 2nd apart from M3 ", enters step 204.

In the step 204, optimum velocity in conveying selection mechanism 80b compares " the 1st distance L 1 " with " the 2nd apart from M2 ".Can also learn that from Fig. 5 B and Fig. 5 C optimum velocity in conveying selection mechanism 80b judges that " the 1st distance L 1 " is shorter than " the 2nd apart from M2 ", enters step 206.In the step 206, select the low speed V1 (low speed) of specific rate V2 (middling speed) at once, be made as SPD=speed V1 (S205).

Speed level at transfer roller 19 is not V3, V2, these 3 patterns of V1, but under the situation more than 4 patterns, in step 206, also carry out the judgement identical with step 204 by optimum velocity in conveying selection mechanism 80b, repeat same judgement in turn, till only being left 1 speed level, select best transfer rate.

Like this, shown in Fig. 5 C, also be the speed of transfer roller 19 with drive motor, accelerate to selected speed V1 (low speed) with certain acceleration, keep certain speed V1 (low speed) afterwards, with certain transfer rate V1 ' transfer sheet P (S207).

In the process of transfer roller 19 with this certain transfer rate V1 ' transfer sheet P, calculating part 80c obtains the difference (L1-M1) that " the 1st distance L 1 " deducts " the 2nd apart from M1 ", as constant speed transmitting range (S208).In addition, this constant speed transmitting range can also be obtained before transfer roller 19 begins with certain transfer rate V2 ' to transmit.

Next, in case be recorded the front end that material sensors 14 detects the record-paper P that is transmitted, just detected signal is sent to control part 80 (S209).Afterwards, allow drive motor continue to be equivalent to the step number part of above-mentioned constant speed transmitting range (L1-M1), continue constant speed and transmit (S209) with certain speed V1 (low speed) rotation.Afterwards, enter moderating process and reduce speed now, stop at and make the front end of record-paper P be positioned at stop position P1 place (S209).

As mentioned above, after the front end of record-paper P stopped in any position of stop position P1, P2, P3, travelling carriage 10 moved to main scanning direction, begins the record of user-selected logging mode.

The speed that shown in Figure 8 is among the embodiment 1 with record-paper P when being sent to stop position P3 as record start position and the curve map of the relation between the time.The longitudinal axis of curve map is represented the speed of drive motor, and transverse axis is represented the time.Solid line is the relevant transfer approach of present embodiment, and dotted line is a former transfer approach.Both all represent the front end of record-paper P is stopped speed and the time relation before to stop position P3.The relevant transfer approach of the former present embodiment, corresponding earlier figures 5A, the latter's transfer approach in the past, corresponding earlier figures 17C.

As shown in Figure 8, in the relevant transfer approach of present embodiment, drive motor is accelerated to speed V3, keep certain speed V3 and be rotated, with certain transfer rate V3 ' transfer sheet P.Afterwards, after being recorded the front end that material sensors 14 detects record-paper P, transmit the constant speed transmitting range with certain speed V3 (certain transfer rate V3 '), reduce speed now afterwards, then the front end of record-paper P stops at stop position P3.The used time of this moment is T1.

In addition, in the former transfer approach, drive motor is accelerated to speed V1, V1 is rotated with certain speed, with speed V1 ' transfer sheet P.Afterwards, after the 2nd sensor 14 detects the front end of record-paper P, keep constant speed to transmit given distance, reduce speed now afterwards, then the front end of record-paper P stops at stop position P3.The used time of this moment is T2.

Here, the area of the ladder diagram of solid line in the curve map, the transmitting range of the record-paper P of the relevant transfer approach of expression present embodiment, its transmitting range is the 1st distance L 3.In addition, because the two all allows the front end of record-paper P stop at stop position P3 place, so the area of the ladder diagram of solid line, equate with the area of the ladder diagram of dotted line.And, between speed V3 and the speed V1, set up following relation:

V3＞V1

The area of the right oblique line of the ladder diagram of solid line part in addition equates with the area of the left oblique line part of the ladder diagram of dotted line.Therefore set up following relation:

T1＜T2

Also be in " blank 5mm pattern ", the present invention can improve disposal ability the deal of the difference of T1 and T2.

As mentioned above, embodiments of the invention 1, has optimum velocity in conveying selection mechanism 80b, if logging mode " non-flanged logging mode " is selected by this mechanism, " blank 3mm pattern ", and in " blank 5mm pattern " any, just by be arranged on the direction of transfer than nozzle opening row 10b more upstream side be recorded material sensors 14, to arrive record start position P1, P2, P3 " the 1st the distance (L1; L2; among the L3 any) ", transfer roller 19 is with from a plurality of friction speed level V3 (at a high speed), V2 (middling speed), a speed level of temporarily selecting among the V1 (low speed) is rotated, and then certain speed zone, begin to the moderating process that stops from deceleration, " the 2nd distance (M3; M2; M1) " that record-paper P is transmitted under certain negative acceleration compares in turn, be shorter than under the condition of above-mentioned " the 1st distance " in this " the 2nd distance ", select above-mentioned a plurality of speed level V3 of above-mentioned transfer roller 19, V2, the fastest speed level among the V1.

Therefore, if select in the above-mentioned logging mode any, just correspondingly be chosen in the scope that does not exceed above-mentioned " the 1st distance " the fastest speed level that can reduce speed now and stop from certain speed.Afterwards, corresponding to above-mentioned record start position P1, P2, P3, by the transfer roller 19 transfer sheet P that are rotated with above-mentioned selected prestissimo level.Therefore, shorten the time that record-paper P is sent to above-mentioned record start position P1, P2, P3 place needs, can improve so-called disposal ability.

In addition, the above-mentioned material sensors 14 that is recorded is arranged on the more close direction of transfer upstream side than above-mentioned opening row 10b in record head 13.Therefore, by above-mentioned " the 1st distance " is provided with bigger, can allow as above-mentioned " the 2nd distance " of distance that then transmits the moderating process of the state that is recorded material with certain speed, big as much as possible.Consequently, corresponding to the part that above-mentioned " the 1st distance " increases, above-mentioned certain speed is also correspondingly selected higher speed level easily.Also promptly, can quite reduce the object that transmits with the low velocity level, thereby can improve disposal ability.

In addition, the front end of the record-paper P that is transmitted at the above-mentioned transfer roller 19 that is rotated by certain speed with the selected speed level of above-mentioned optimum velocity in conveying selection mechanism 80b, be recorded after material sensors 14 detects by above-mentioned, transmit the difference of above-mentioned " the 1st distance " and " the 2nd distance " with above-mentioned certain speed, enter moderating process afterwards, reducing speed now stops subsequently.Therefore also promptly, after sensor 14 detects the front end of record-paper P, also keep certain speed to transmit above-mentioned difference, can realize a kind of small-sizedly and can not reduce the design freedom of sensor in being provided with, can improve tape deck with paper stop position precision.

In addition, above-mentioned optimum velocity in conveying selection mechanism 80b, in above-mentioned a plurality of friction speed level V3 (at a high speed), V2 (middling speed), V1 (low speed), according to the higher order of speed level (V3 → V2 → V1) above-mentioned " the 2nd distance " and above-mentioned " the 1st distance " are compared, when meeting above-mentioned condition, select this speed level.Therefore, and compare according to lower order of speed level or situation about relatively selecting arbitrarily, can be as early as possible the close speed level of the condition of stating of selector easily.

For example, under the situation of the raising (attention writing speed) of paying attention to disposal ability, select the deceleration curve C1 of the high speed that is a significant slowdown, by so as shown in Figure 9, the zone of the preceding certain speed V of beginning of slowing down can be increased, thereby the raising of disposal ability can be easily realized.In addition, comparing, more paying attention to selecting the deceleration curve C3 of the mild low speed that slows down under the situation of record quality,, stopping at accurately on the target stop position by improving the stop position precision like this with the raising of disposal ability.

[embodiment 3]

Contrast Figure 12 to Figure 16 describes the embodiment 3 of relative recording device of the present invention.Figure 12 for the speed that in the relative recording device of expression embodiment 3 record-paper is sent to record start position (stop position) with apart from and different deceleration curve between the curve map of relation, Figure 13 is the frame assumption diagram of this tape deck, and Figure 14 to Figure 16 is in this tape deck being sent to record-paper the flow chart of the record-paper transfer approach of each record start position.

In the tape deck of embodiment 3, its control part 84 is the same with embodiment 1 and embodiment 2, blank about record-paper P front end has 3 logging modes " non-flanged logging mode ", " blank 3mm pattern " and " blank 5mm pattern ", has above-mentioned " the 1st distance (L1, L2, L3) " about the information of record start position P1, P2 different in each logging mode, P3 simultaneously as form 1.

In addition, control part 84 is the same with embodiment 1, has information (high speed V3, middling speed V2, low speed V1) about above-mentioned 3 speed levels of transfer roller 19 as form 3.

Control part 84 is the same with embodiment 2 in addition, has a plurality of different deceleration curve C1, C2, the information of C3, as the deceleration zone in the zone of the certain speed of following above-mentioned transfer roller 19.

Corresponding to this deceleration curve C1, C2, C3, above-mentioned each speed (V3, V2, V1) to above-mentioned transfer roller 19, as the then deceleration zone in its constant speed zone respectively, have corresponding high slope deceleration curve C1 the deceleration zone apart from the deceleration zone of the deceleration curve C2 of slope in N1 (V3), N1 (V2), N1 (V1), the correspondence apart from the deceleration zone of the deceleration curve C3 of N2 (V3), N2 (V2), N2 (V1) and corresponding low slope apart from N3 (V3), N3 (V2), N3 (V1).

The magnitude relationship of regional above-mentioned each distance of slowing down is following relation as shown in figure 12.For example, be N3 (V3)＞N2 (V3)＞N1 (V3), too for other speed levels V2, V1 for a speed level V3 of transfer roller 19.In addition, for 1 deceleration curve, deceleration curve C3 for example, magnitude relationship for 3 speed levels (V3, V2, V1) of corresponding transfer roller 19, deceleration distance is the relation of N3 (V3)＞N3 (V2)＞N3 (V1), about other deceleration curves C2, C1 too, be the relation of N2 (V3)＞N2 (V2)＞N2 (V1), N1 (V3)＞N1 (V2)＞N1 (V1).

Also promptly, control part 84 have with 3 speed levels (V3, V2, V1) of transfer roller 19 and 3 deceleration curve C1, C2, C3 corresponding " the 2nd distance (N1 (V3), N1 (V2), N1 (V1), N2 (V3), N2 (V2), N2 (V1), N3 (V3), N3 (V2), N3 (V1)) " as form 2.Here, different deceleration curves is the same with embodiment 2 in present embodiment 3, the following setting.Also promptly, the corresponding record of paying attention to writing speed of the deceleration curve C1 of high slope is set, and the corresponding record of paying attention to the record position precision of the deceleration curve C3 of low slope is set, and the record of the deceleration curve C2 correspondence quality between the two of middle slope is set.

In the control part 84, has optimum velocity in conveying selection mechanism 84b, if any in the logging mode selected by the user by this mechanism, and selected any of deceleration curve, just will be corresponding with it " the 1st distance (L1, L2, L3) ", with relative selected 1 deceleration curve, compare corresponding to " the 2nd distance " according to the temporary transient speed level of selecting of the order of defined, be shorter than in " the 2nd distance " under the condition of " the 1st distance ", select the fastest speed level in above-mentioned 3 speed levels (V3, V2, V1) of above-mentioned transfer roller 19.In the present embodiment, above-mentioned optimum velocity in conveying selection mechanism 84b, in 3 speed levels (V3, V2, V1), the higher order of speed level with above-mentioned " the 2nd distance " and above-mentioned " the 1st distance " in turn, for example deceleration curve C3 is compared according to the order of N3 (V3) → N3 (V2) → N3 (V1), when meeting above-mentioned condition, select this speed level.

And then control part 84 has the calculating part 84c that calculates the constant speed transmitting range.This calculating part 84c, front end at the record-paper that is transmitted by above-mentioned transfer roller 19 with the rotation of the certain speed of the selected speed level of above-mentioned optimum velocity in conveying selection mechanism 84b, be recorded after material sensors 14 detects by above-mentioned, calculate maintenance with the distance that the certain speed constant speed transmits, the difference of obtaining " the 1st distance " and " the 2nd distance " is as this constant speed transmitting range.

Next, the effect to embodiment 3 describes.Select any logging mode in " non-flanged logging mode ", " blank 3mm pattern ", " the blank 5mm pattern " by the user by not shown selection mechanism (known selector switch etc.), with this recording mode selection information, send to control part 84 as shown in figure 13.And then select among deceleration curve C1, C2, the C3 any by the user, this deceleration curve selection information is sent to control part 84.

For example, selected the user under the situation of " blank 5mm pattern ", the front end stop position of record-paper P is P3.Therefore, decision " the 1st distance L 3 " (S401).Selected to judge in the step 402 under the situation of " low slope deceleration curve C3 " the user afterwards, entered step 403.Next, optimum velocity in conveying selection mechanism 84b compares " the 1st distance L 3 " " the 2nd apart from N3 (V3) " with the deceleration curve C3 of corresponding low slope.If judge " the 1st distance L 3 ", just, select speed level V3 (at a high speed) (S404) as SPD=speed V3 than " the 2nd apart from N3 (V3) " long (S403).In addition, judge the 1st distance L 3 with the 2nd apart from the identical situation of N3 (V3) under (S403), also select speed level V3 (at a high speed) (S404).

Afterwards, as shown in figure 12, also be the speed of transfer roller 19 with drive motor, accelerate to selected speed V3 (at a high speed) with certain acceleration, keep certain speed V3 (at a high speed) afterwards, with certain transfer rate V3 ' transfer sheet P (S409).

In the process of transfer roller 19 with this certain transfer rate V3 ' transfer sheet P, calculating part 84c obtains the difference (L3-N3 (V3)) that " the 1st distance L 3 " deducts " the 2nd apart from N3 (V3) ", as constant speed transmitting range (S410).In addition, this constant speed transmitting range can also be obtained before transfer roller 19 begins with certain transfer rate V3 ' to transmit.

Next, in case be recorded the front end that material sensors 14 detects the record-paper P that is transmitted, just detected signal is sent to control part 84 (S411).Afterwards, allow drive motor continue to be equivalent to the step number part of above-mentioned constant speed transmitting range (L3-N3 (V3)), continue constant speed and transmit (S411) with certain speed V3 (at a high speed) rotation.Afterwards, enter moderating process and reduce speed now, stop at and make the front end of record-paper P be positioned at stop position P3 place (S411).By like this, can carry out the record of paying attention to the record position precision with high throughput.

In addition, selected " blank 3mm pattern " the user, and selected under the situation of " low slope deceleration curve C3 ", the front end stop position of record-paper P is P3 rather than P2.Therefore, decision " the 1st distance L 2 " (S401).Next, judge the user in the step 402 and selected " low slope deceleration curve C3 ", enter step 403.Next, optimum velocity in conveying selection mechanism 84b at first compares (S403) with " the 2nd apart from N3 (V3) " with " the 1st distance L 2 ".In the example shown in Figure 12,, therefore enter step 405 because " the 1st distance L 2 " is shorter than " the 2nd apart from N3 (V3) ".

Optimum velocity in conveying selection mechanism 84b with " the 1st distance L 2 " with compare corresponding to " the 2nd apart from N3 (V2) " of the slow speed V2 (middling speed) of specific rate V3 (at a high speed).Like this, if optimum velocity in conveying selection mechanism 84b judgement " the 1st distance L 2 " is longer than " the 2nd apart from N3 (V2) " (S405),, be made as SPD=speed V2 (S406) just select speed level V2 (middling speed).In addition, judging under " the 1st distance L 2 " situation identical (S405), also select speed level V2 (middling speed) (S406) with " the 2nd apart from N3 (V2) ".

(processing of S409 → S411) is compared basically not change with the above-mentioned processing under the situation of having selected speed level V3 (at a high speed), therefore omits explanation to have selected afterwards each step of speed level V2 (middling speed).

In addition, selected the user " non-flanged logging mode ", and selected under the situation of " low slope deceleration curve C3 ", the front end stop position of record-paper P is P1.Therefore, decision " the 1st distance L 1 " (S401).Next, optimum velocity in conveying selection mechanism 84b through step 402, compares " the 1st distance 1 " in step 403 with " the 2nd apart from N3 (V3) ".Can learn that from Figure 12 optimum velocity in conveying selection mechanism 84b judges that " the 1st distance L 1 " is shorter than " the 2nd apart from N3 (V3) ", enters step 405.

In the step 405, optimum velocity in conveying selection mechanism 84b compares " the 1st distance L 1 " with " the 2nd apart from N3 (V2) ".Can learn that from Figure 12 optimum velocity in conveying selection mechanism 84b judges that " the 1st distance L 1 " is shorter than " the 2nd apart from N3 (V2) ", enters step 407.

Optimum velocity in conveying selection mechanism 84b with " the 1st distance L 1 " with compare (S407) corresponding to " the 2nd apart from N3 (V1) " of the slow speed V1 (low speed) of specific rate V2 (middling speed).Like this, if optimum velocity in conveying selection mechanism 84b judgement " the 1st distance L 1 " is longer than " the 2nd apart from N3 (V1) " (S407),, be made as SPD=speed V1 (S408) just select speed level V1 (low speed).In addition, judging under " the 1st distance L 1 " situation identical (S407), also select speed level V1 (low speed) (S408) with " the 2nd apart from N3 (V1) ".

(processing of S409 → S411) is compared basically not change with the above-mentioned processing under the situation of having selected speed level V3 (at a high speed), therefore omits explanation to have selected afterwards each step of speed level V1 (low speed).

In addition, in the example of Figure 12, optimum velocity in conveying selection mechanism 84b judges that " the 1st distance L 1 " is shorter than " the 2nd apart from N3 (V1) ", the message that output can't executive logging, end process.In addition, such combination that can't executive logging preferably preestablishes above table, makes the user to select.

Figure 15 is the flow chart of the processing under the situation of the deceleration curve C2 of slope in the explanation user selection.Have only the 2nd distance to become " N2 (V3), N2 (V2), N2 (V1) " from " N3 (V3), N3 (V2), N3 (V1) ", to the step (S403 → S411) identical that illustrated among the basic handling of each logging mode " non-flanged logging mode ", " blank 3mm pattern ", " blank 5mm pattern " and Figure 14, therefore to its mark corresponding symbol (S503 → S511), detailed.

In addition, in the example of Figure 12, " blank 5mm pattern " and " blank 3mm pattern " selects speed level V3 (at a high speed) all as SPD=speed V3." non-flanged logging mode " selects speed level V1 (low speed) as SPD=speed V1.

Figure 16 selects the flow chart of the processing under the situation of deceleration curve C1 of high slope for the explanation user.Have only the 2nd distance to become " N1 (V3), N1 (V2), N1 (V1) " from " N3 (V3), N3 (V2), N3 (V1) ", to the step (S403 → S411) identical that illustrated among the basic handling of each logging mode " non-flanged logging mode ", " blank 3mm pattern ", " blank 5mm pattern " and Figure 14, therefore to its mark corresponding symbol (S603 → S611), detailed.

In addition, in the example of Figure 12, " blank 5mm pattern ", " blank 3mm pattern " and " non-flanged logging mode " are selected speed level V3 (at a high speed) all as SPD=speed V3.

In addition, the present invention is not limited in the foregoing description, in the scope of invention that can also be put down in writing within the scope of the claims, carries out various distortion, and these distortion include in scope of the present invention.
