Description
Technical field
The present invention relates to a kind of means for moving printing medium, especially relate to a kind of being arranged in the printer, have one first medium mobile module, one second medium mobile module and a control module and this control module and optionally enable this first medium mobile module or this second medium mobile module and control a means for moving printing medium that moves of printing medium.
Background technology
Generally speaking, color printer can probably be divided into dot matrix printer, ink-jet printer, laser printer and heat sublimation (being also referred to as hot transfer printing) printer four big classes, wherein, thermal printer utilizes heat-transferring head (thermal print head) to heat colour band, dye transfer on the colour band is printed on the thing to waiting, and just formed continuous color range according to the time length of heating or the temperature of heating.Because heat sublimation type printer prints quality is splendid, have continuity in the performance of tone, can make the photograph color that prints off more natural, be fit to the printer of development digital camera special use, so more and more be subjected to the attention in market.
The mode of operation of thermal printer can be divided into two kinds of printing model and advance and retreat paper matrix formulas according to the demand of print job, this is because the dyestuff on the different colours colour band need separately be transferred on the thing to be printed (for example paper), therefore, when thermal printer is in printing model following time, motor can drive wait to print thing by an initial position towards a direction advance so that the dye transfer on certain color colour band to thing to be printed, then, thermal printer just can be converted to advance and retreat paper matrix formula, motor just drives to be waited to print thing and is back to this original position in the direction, when being converted to printing model once more with the mode of operation of convenient thermal printer, but the dyestuff on the another kind of color colour band of transfer printing is to thing to be printed.
See also Fig. 1, Fig. 1 is the rough schematic view of the means for moving printing medium 100 of existing thermal printer.Means for moving printing medium 100 includes a stepper motor 110, a drive pulley 122, a belt 124, a driven pulley 126, an active roller (capstan roller) 132 and one passive roller (pinch roller) 134.As shown in Figure 1, drive pulley 122 is coupled to stepper motor 110, and driven pulley 126 is coupled to active roller 132, drive pulley 122 then couples mutually via belt 124 with driven pulley 126, therefore, power just can be by stepper motor 110 via drive pulley 122, belt 124, driven pulley 126 and be passed to active roller 132 so that active roller 132 rotates, active roller 132 all contacts with a printing medium 10 (for example: a paper or a card) with passive roller 134 again, can drive passive roller 134 when active roller 132 rotates rotates together, and drive print media 10 in the lump or be moved to the left to the right, wherein, the moving direction of print media 10 is decided by the rotation direction of active roller 132, for instance, if by direction shown in Figure 1, when active roller 132 turns clockwise, will drive passive roller 134 and be rotated counterclockwise, print media 10 just can move right (printing/advance and retreat paper matrix formula); Otherwise, when active roller 132 is rotated counterclockwise, will drives passive roller 134 and turn clockwise, print media 10 just can be moved to the left (advance and retreat paper/printing model).
In order to ensure print quality, can wish that the motor output of working has the characteristic of high torsion under printing model, and in order to improve printing effect, can wish that then the motor output of working has high-revolving characteristic under advance and retreat paper matrix formula, and stepper motor is decided the performance of its rotating speed and torsion by stator winding, yet, under identical driving voltage, the mutual exclusion condition that shows as of rotating speed and torsion that is to say, stepper motor only has the high torsion slow-speed of revolution or the high-revolving output characteristics of low torsion, again from the above, prior art is only utilized single stepper motor to drive active roller and is rotated, and then can cause printing effect to descend if consider print quality, if require high printing effect then can sacrifice print quality, therefore, for reaching the performance of omnidistance high rotating speed and high torsion, just must use high voltage or big electric current to come CD-ROM drive motor, in the case, except energy charge is big, the volume of required stepper motor also can be bigger, and motor almost do not have time of having a rest, and can cause the too high problem of motor temperature.
Summary of the invention
