A kind of Self-printing terminal
Technical field
The present invention relates to the Possum technical field, be specifically related to a kind of Self-printing terminal.
Background technology
Such as Self-printing terminals such as queue machine, self-inquiry terminals, all can use the documents such as temperature-sensitive (or pin type) the printer number of printing ticket, authority or invoice.In general, the document that prints has hemisection and entirely cuts dual mode.Partly cut out when single when adopting, after the user stretched out one's hand and takes document, the document that needs not cut fully tore from printer.This kind mode easily printing paper is drawn partially and when causing printer paperboard, especially document also not to print the user just pull document, although perhaps document has been printed, user's pulling force secund just easily draws printing paper partially.
Adopt single mode that entirely cuts out in the up-to-date technology, printed document is cut off the rear user of confession fully take.Part adopts the Self-printing terminal (such as ATM) that entirely cuts out ticket, its printer carries feeder, document is after printing fully, send at a high speed by feeder again, but this printer with feeder is expensive, require simultaneously the space in the rack larger, be not suitable for the rack of ultra-thin outward appearance.
The most of employing cuts out single Self-printing terminal entirely now, (only illustrate among the figure and print the relevant portion structure in the rack) as depicted in figs. 1 and 2, in rack 1, be fixed with printing paper roll 2, introduce from the paper feed port 41 of printer 4 from the print paper 3 that printing paper roll 2 pulls out, document 5 after printed is sent through the exit slot 42 of printer 4, and is cut off fully from print paper 3 by printer 4.Document 5 after the cut-out descends slowly and lightly to single chamber 7 that falls by deadweight, takes for the user.This kind mode causes print paper 3 to be drawn the problem that partially causes printer 4 paperboards because document 5 is cut off from print paper 3 fully thereby avoided the user to pull document 5.
But because print paper 3 pulls out from printing paper roll 2, thereby always have to a certain degree bending.During beginning, because the diameter of printing paper roll 2 is larger, document 5 is more straight comparatively speaking.Descend slowly and lightly on the ground by getting single port 8 for fear of document 5, the position near printer 4 exit slots 42 on rack antetheca 12 is provided with a baffle plate 6.
But, the baffle plate 6 of existing Self-printing terminal is all fixed, increase along with printing amount, the diameter of printing paper roll 2 can be more and more less, the document 5 that prints can be more and more curling, cause document 5 may be stuck in baffle plate 6 and fall between falling of single chamber 7 single chamber rear wall 9 and can not descend slowly and lightly to falling 7 bottoms, single chamber, thereby bring inconvenience for the user.This kind situation is particularly serious on ultra-thin rack 1, because the distance between the rack rear wall 11 of ultra-thin rack 1 and the rack antetheca 12 is limited, is difficult to solve simultaneously and is stuck when document 5 falls and descends slowly and lightly to problem on the ground, therefore needs to improve.

The specific embodiment
A kind of Self-printing terminal that the concrete real-time mode of the present invention provides is shown in Fig. 3 (only illustrate among the figure and print the relevant portion structure in the rack), be with the difference of prior art, it has adopted a cover self adaptation to keep off single device and replace baffle plate 6 of the prior art.
This self adaptation is kept off single device and is had sideboard 6, and self adaptation is kept off single device can adjust the position of sideboard 6 automatically according to the variation of printing paper roll 2 diameters, with the document 5 that adapts to different amount of crimp.Larger at printing paper roll 2 diameters, when document 5 is more straight, so that sideboard 6 can not descend slowly and lightly on the ground with guarantee document 5, nor can be stuck between paper chamber rear wall 9 and the sideboard 6 near the paper chamber rear wall 9 that falls (the in other words exit slot 42 of close printer 4); Diminish gradually at printing paper roll 2 diameters, when document 5 becomes more and more curling, so that sideboard 6 is gradually away from the paper chamber rear wall 9 that falls, can not be stuck between paper chamber rear wall 9 and the sideboard 6 with guarantee document 5, nor can descend slowly and lightly on the ground, prior art exists thereby solved very cleverly, under rack 1 thinner case, is difficult to solve simultaneously document 5 and falls Shi Buhui and be stuck and descend slowly and lightly to problem on the ground.
As shown in Figure 3 and Figure 4, described self adaptation is kept off single device except comprising sideboard 6, also comprises the feedback driving mechanism.The upper end of sideboard 6 is hinged fixing, particularly is rotatably connected by hinge and rack 1 in this specific embodiment, so that sideboard 6 can rotate by A point (rotating shaft of hinge) in Fig. 4.The variation of feedback driving mechanism energy perception printing paper roll 2 diameters, and according to this variation, drive sideboard 6 around the pin joint (A point) of one end, rotate within the specific limits, thereby make sideboard 6 near or away from the paper chamber rear wall 9 that falls, with the document 5 that adapts to different amount of crimp.
The feedback driving mechanism specifically comprises in this specific embodiment: lever 62 and slide block 64.Described lever 62 has fulcrum C, and can rotate around fulcrum C.Described slide block 64 slidably is arranged on an end of lever 62, and an end of slide block and sideboard 6 is hinged.Sideboard 6, lever 62 and slide block 64 consist of double-lever mechanism.And the other end of lever 62 is under lever 62 self gravitation effects, near the outer surface of printing paper roll 2, thus variation that can perception printing paper roll 2 diameters.When the diameter of printing paper roll 2 diminishes, lever 62 clockwise rotates around its fulcrum C, the other end of 64 relative levers 62 of slide block slides, and the pin joint A of drive sideboard 6 around its upper end rotates counterclockwise, thereby make sideboard 6 away from the paper chamber rear wall 9 that falls, to adapt to more and more curling document 5.
In the preferred technical scheme, described feedback driving mechanism also comprises the contact warranty element, described contact warranty element is connected with lever 62 mechanics, guarantee that an end of lever 62 reliably contacts with the outer surface of printing paper roll 2, thereby accurate response is made in the variation of guaranteeing 62 pairs of printing paper roll 2 diameters of lever.
Particularly, the contact warranty element is extension spring 63 in this specific embodiment.Extension spring 63 is arranged at the left side (being positioned at the same side of lever 62 with printing paper roll 2) of lever 62, and its a end is connected with rack 1 (can certainly be the mounting article that other can be stressed), the other end is connected with an end of outer surface contact lever 62 and printing paper roll 2, with the elastic force that its tension produces, guarantee that an end of lever 62 reliably contacts with the outer surface of printing paper roll 2.
Certainly, extension spring 63 also can be arranged on the right side of lever 62, but should be connected with the other end of lever 62 this period, and one of ordinary skill in the art is understood that, it also can with the elastic force of its tension generation, guarantee that an end of lever 62 reliably contacts with the outer surface of printing paper roll 2.
One of ordinary skill in the art also is understood that, extension spring 63 also can change stage clip into; One of ordinary skill in the art also is understood that, extension spring 63 also can change rubber bar (rubber band) into, reliably contacts with the outer surface of printing paper roll 2 as long as can reach an end of guaranteeing lever 62, namely should be within the application's protection domain.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
