Bottom illustrates its action.Figure 10 is the flow chart of explanation by the paper feeding processing sequence of MPU 55 enforcements.This program is implemented by per stipulated time by MPU 55.At first, MPU 55 judges that having denys necessary paper feeding (S1).That is, during owing to printing, the lettering of the conveying of printing 8 and print head 31 carries out alternately, and whether must at first understand now is the 8 needed conveyings moment of printing.
Paper feeding if desired (S1:Yes), MPU 55 is with the common speed drive stepper motor 11 (S2) of regulation.Particularly, MPU 55 is to stepper motor 11 supply drive pulses, and only the step number with regulation drives stepper motor 11.In the present embodiment, to common literal lettering the time, 24 steps drove stepper motor 11 and carry out lettering, and then 36 step-lengths drive lettering, 24 steps were driven drive with 36 step-lengths to carry out alternately repeatedly.In addition, when the view data lettering, carry out the action that 24 steps drove stepper motor 11 letterings repeatedly.
Secondly, MPU 55 judges whether to carry printing 8 (S3) with predetermined distance.Whether particularly, MPU 55, to the umber of pulse counting from the detection signal of photoelectric sensor 21, based on its counting, calculate the actual displacement of printing 8, understand such as being equivalent to about 24 step-lengths of stepper motor 11.At this moment, owing to counting the situation that does not go out pulse with the detections such as conversion of detection signal is arranged at the end during the counting beginning, preestablish the error allowed band, if the above printing 8 of carrying about 22 steps with few 2 steps promptly is considered to carry printing 8 with predetermined distance.
If do not carry printing 8 (S3:NO) with predetermined distance, MPU55 is with the speed drive stepper motor 11 (S4) lower than common speed.Particularly, MPU55 calculates the distance of not carrying, and only drives the step number that stepper motor 11 is equivalent to this distance.At this moment, owing to driven at low speed stepper motor 11, can eliminate the step-out of stepper motor 11, the possibility of printing 8 can be normally carried in raising.
Then, MPU55 judges whether to carry printing 8 (S5) with predetermined distance.At this moment concrete action is with step S3.
If printing is transferred predetermined distance (S5:Yes), MPU 55 promptly drives lettering portion 4 and carries out lettering (S6), and this program ends.
In step S5, if printing 8 is not transferred predetermined distance (S5:NO), MPU 55 promptly reports the meaning (S7) that produces jam, and this program ends.This reporting can will produce the jam meaning with literal or mark etc. such as (not shown) in the display frame of the display unit that printing equipment had and show.Certainly, also can on this basis of reporting, represent to show releasing guidance etc.Also can replace the demonstration of this display unit in addition or on showing, increase the alarm sound of toot moving qin sound or buzz etc.
In step S3, be transferred predetermined distance (S3:Yes) as printing 8, enter step S6.
In step S1, as unnecessary paper feeding (S1:NO), this program stops.
Like this, because having to draw, printing machine rolls 5, roller 17, rotate code wheel 20, photoelectric sensor 21, wherein dilatoryly roll 6 and be used for carrying printing 8 along prescribed path, roller 17 is connected to printing 8 and only turns over angle corresponding to printing 8 displacements, rotate that code wheel 20 only rotates the angle identical with roller 17 and on the concentric circles that with the center of rotation is the center in accordance with regulations pitch form a plurality of detected portion, 21 detections of passing through the detected portion of rotating code wheel 20 of photoelectric sensor, the whenever mobile predetermined distance of printing 8 is sent detection signal, therefore, based on the detection signal that sends from photoelectric sensor, can high accuracy judge the conveying situation of printing 8.
In addition, because printing machine has the dilatory photoelectric sensor 21 that rolls 5, detects printing 8 actual displacements of carrying printing 8 along prescribed path, by based on dilatory 5 MPU 55 that control the stop position of printing 8 that roll of photoelectric sensor 21 testing results control, so can roll 5 by printing 8 actual displacements being fed back to draw, come high accuracy control printing 8 stop positions.
Also have, by photoelectric sensor 21 detected actual displacements than rolling 5 and should carry displacement to lack predetermined distance when above by dilatory, the instruction of answering low speed to carry printing 8 only to be equivalent to the distance of its difference passed to dilatoryly roll 5, roll 5 and carry after the printings 8 according to this instruction is dilatory, by photoelectric sensor 21 detected actual displacements than rolling 5 and should carry displacement to lack the regulation ratio when above by dilatory, it is judged as conveying takes place unusual with paper, but so high accuracy control printing 8 stop positions, simultaneously, the imbalance of syncmotor 11 can be eliminated by driven at low speed, the possibility of normal conveying printing 8 can be improved.
In the above-described embodiments, detect the feed status of printing 8 by rotating the combination of code wheel 20, but as shown in figure 11, also can detect the feed status of printing 8 by the slide-rule dial dish 61 and the combination of infiltration type photoelectric sensor with photoelectric sensor 21.Slide-rule dial dish 61 is the many wire of radial formation slits 63 on thin plectane 62.Slit 63 is being on the circumference at center such as being processed by methods such as corrosion with plectane 62 centers, forms with for example superfine fine pith about 80 μ m.
Or as shown in figure 12, also can detect the feed status of printing 8 by the line dial 71 and the combination of reflective photoelectric sensor, line dial 71 is that the many linear reflection bodies 73 of radial formation form on plectane 72.Reflector 73 such as can be by method settings such as printings, be on the circumference at center to form such as the superfine little pitch in the 80 μ m left and right sides at the center with plectane 72.Plectane 72 can absorb from the next light of photoelectric sensor.Can certainly be without reflector 73, and the light that absorber absorbs photoelectric sensor is set.At this moment, as plectane 72, also can use the mechanism of reflection from the next light of photoelectric sensor.
If use such line dial 61 or line dial 71, can carry out than use rotating under code wheel 20 situations more high-precision test.Such as, when 1 step-length of stepper motor 11 is equivalent to 180dpi (byte) character-display unit, the whenever mobile 0.141mm of printing 8, promptly send the detection pulse in 1 cycle from photoelectric sensor, as set the pitch of slit 63 or reflector 73, be that 1 step-length of every driving stepper motor can obtain 1 cycle detection pulse,, also be very easy to control carrying out the very high degree of precision detection simultaneously.Promptly, by to the driving pulse of stepper motor 11 with compare from the detected pulse of photoelectric sensor, 1 step-length that promptly can stepper motor 11 is the conveying situation that printing 8 is judged by unit, therefore, can easily control the transporting velocity and the fed distance of printing 8 by the MPU55 high accuracy by based on the control of the detection pulse of sending to stepper motor 11 from photoelectric sensor.Thereby, can detect jam rapidly before stopping fully because printing 8 transporting velocities are reduced in printing 8.
In addition, in the above-described embodiments, constitute by 1 MPU55 and control whole printing equipment, also can establish a plurality of MPU, at this moment share function arbitrarily by each MPU.
In the above-described embodiments, used continuous paper, even but the present invention's printing is interrupted paper also can effectively utilize as printing 8.
