As shown in Figure 1, the front side wall of paper supplemental tank 300 is located at the rear side of the front side wall of paper placing groove 100.
As shown in Figure 1, sheet support slides the width in the front-back direction of pedestal 52 and the front-rear direction of paper supplemental tank 300
Width it is equal.
The operation principle of the paper supplementary device of printer:
Original state:Several sheet support units are evenly distributed on the lower part of paper supplemental tank 300, length limiting plate up and down
44 are in front end, and right width limiting plate 43 be in the upper surface of bottom and right width limiting plate 43 and paper placing groove
100 bottom surface is concordant;
Start width driving motor 42 first and left width limiting plate 41 and the limiting of right width are adjusted by rack pinion
Gap between plate 43, then the artificial disposable sheet support toward all sheet support units slides places paper on pedestal 52
, when requiring supplementation with paper in input tray 10, the sheet support lifting pedestal 51 of the sheet support unit of the top rises directly
Concordant with the bottom surface of paper placing groove 100 to the lower face of sheet support lifting pedestal 51, then sheet support slides pedestal 52
It is moved to the left, the paper during sheet support slides pedestal 52 thereon can be stopped by left width limiting plate 41 until paper
Support slides pedestal 52 and reaches left end, and then right width limiting plate 43 rises through sheet support and slides pedestal 52, such paper
It opens and is positioned by left width limiting plate 41 and right width limiting plate 43, then sheet support slides 52 return of pedestal, sheet support liter
Drop pedestal 51 continues to rise until the top of paper supplemental tank 300, and final length limiting plate 44, which travels forward, abuts against paper
Primary benefit paper is so far completed in front end, and follow-up paper principle of mending is same as above, and is effectively reduced the artificial number for mending paper in this way;It props up simultaneously
20 inner hollow of support, can place blank sheet of paper, effectively using space, reduce the time for looking for blank sheet of paper everywhere.
More than content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes, the content of the present specification should not be construed as to this hair in specific embodiments and applications
Bright limitation.
