Further, said yardage checkout gear is a laser range sensor.
Further, said yardage checkout gear comprises two groups of Hall elements that are set up in parallel along sheet transport direction, the distance between two groups of Hall elements and the equal in length of individual paper.
Further, said yardage checkout gear is that the paper stranding send roller, said stranding to send roller to equate with the full-length of paper.
Further; Said printer paper feed paper disc upper edge sheet transport direction is provided with two groups of Hall elements; The distance between two groups of Hall elements and the equal in length of individual paper, the detection signal input controller of two groups of Hall elements, the controller control transport of cutting a sheet of paper.
Further, said printer paper feed paper disc is provided with sheet-transport belt or paper transfer roller.
Further, said paper feeding cassette is the roll web paper feeding cassette.
Further, said paper feeding cassette is the folding paper paper feeding cassette.
Further, said paper feeding cassette and cut a sheet of paper to be provided with between the transport and scrape mechanism of paper, the said mechanism of paper of scraping comprises vertical with a sheet transport direction paper slip of scraping.
The beneficial effect of the utility model: individual paper-advance unit of the printer of the utility model, comprise paper feeding cassette, the transport of cutting a sheet of paper, printer paper feed paper disc and the controller arranged successively along paper feed path, the said transport of cutting a sheet of paper is provided with the yardage checkout gear; The detection signal input controller of yardage checkout gear, controller is controlled the transport of cutting a sheet of paper, during use; To be put in without the paper stock of cutting in the paper feeding cassette; Through sending into printer paper feed paper disc after the cutting of cutting transport fixed length, realize individual paper feed, effectively avoided plurality of sheets of paper to stack the paperboard that paper supply way causes; Improved printing effect; Cut the waste, simultaneously, also make the longer service life of printer.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model, dotted line representation signal transmission route among the figure.
The specific embodiment
Below will combine accompanying drawing that the utility model is elaborated, as shown in the figure: individual paper-advance unit of the printer of present embodiment comprises paper feeding cassette 1, the transport 2 of cutting a sheet of paper, printer paper feed paper disc 3 and the controller 4 arranged successively along paper feed path; The said transport 2 of cutting a sheet of paper is provided with yardage checkout gear 5, and the transport of cutting a sheet of paper comprises mechanism for cutting sheet and conveying mechanism, and conveying mechanism comprises at least two group pinch rolls; One group is arranged at the mechanism for cutting sheet front portion, and another group is arranged at the mechanism for cutting sheet rear portion, is respectively applied for the paper of carrying not cutting and individual paper after the cutting; In the present embodiment, said yardage checkout gear 5 is selected laser range sensor for use, can accurately detect the length of paper sheet delivery; And it is simple in structure; The detection signal input controller 4 of yardage checkout gear 5, controller 4 is controlled the transport 2 of cutting a sheet of paper, when the paper sheet delivery distance reaches the length of individual paper; The conveying mechanism that controller is controlled the transport of cutting a sheet of paper stops; And control its mechanism for cutting sheet startup, and paper is carried out the fixed length cutting, the paper after the cutting is sent into the printer paper feeding plate; Realize individual paper feed, thoroughly avoid occurring plurality of sheets of paper and stack the paperboard problem that paper supply way produces.
Certainly; Said yardage checkout gear 5 also can adopt Hall element to realize; This sensor comprises two groups of Hall elements that are set up in parallel along sheet transport direction, and the distance between two groups of Hall elements and the equal in length of individual paper begin the length of having carried individual paper just to through second Hall element through first Hall element when top of form; Controller control this moment conveying mechanism stops, and control mechanism for cutting sheet startup carrying out cutting.
In addition, said yardage checkout gear 5 also can adopt the paper stranding to send roller, said stranding to send roller to equate with the full-length of paper; Paper knife is arranged on to rub with the hands and send on the roller; Stranding send roller to rotate a week, carries the length of a piece of paper just, simultaneously; Paper knife carries out paper is separated, and can realize the purpose of fixed length cutting equally.
As the further improvement of technique scheme, said printer paper feed paper disc 3 upper edge sheet transport direction are provided with the equal in length of distance and individual paper between 6, two groups of Hall elements 6 of two groups of Hall elements; The detection signal input controller 4 of two groups of Hall elements 6; Controller 4 is controlled the conveying mechanism of the transport 2 of cutting a sheet of paper, and is used to detect whether paper is arranged on the paper disc, as when the Hall element detection that is positioned at the throughput direction front end exists less than paper; Controller is controlled the transport of cutting a sheet of paper and is started; The beginning paper feed is prepared cutting, when the Hall element detection that is positioned at the throughput direction rear end exists less than paper, proves that paper has got into printer; This moment, controller was controlled the transport cutting paper of cutting a sheet of paper, and opened to printer paper feed paper disc conveying single paper.
Further improvement as technique scheme; Said printer paper feed paper disc 3 is provided with sheet-transport belt 3a or paper transfer roller; Can the paper propelling movement be put in place through sheet-transport belt or paper transfer roller, prevent that erroneous detection from appearring in the Hall element that is positioned on the printer paper feed paper disc.
As the further improvement of technique scheme, said paper feeding cassette 1 is the folding paper paper feeding cassette, uses folding paper to substitute plurality of sheets of paper as the former material of paper and opens the mode that stacks, and it is convenient to change.Certainly, adopt roll web to put into paper feeding cassette, can achieve the above object equally as the former material of paper.In addition; Folding paper also can adopt both sides to have the folding paper of sprocket hole, and gear capable of using is accurately carried, when adopting folding paper; Said paper feeding cassette 1 and cut a sheet of paper to be provided with between the transport 2 and scrape mechanism of paper 7; The said mechanism of paper 7 of scraping comprises vertical with a sheet transport direction paper slip of scraping, can be effectively be that the paper that scatters scrapes off when carrying, prevent two pages of folding transports of cutting a sheet of paper that get into.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
