The paper feeding passage of the printer is provided with an excursion detecting sensor which has a certain distance with the paper emptying sensor on the horizontal direction, and the output of the excursion detecting sensor is connected with a CPU of a control circuit of the printer. The excursion detecting sensor can be parallel to the paper emptying sensor. Because the excursion detecting sensor is added on the utility model, the printer can automatically detect the excursion and frequent paper feeding phenomenon resulting from the printing excursion and the paper excursion is avoided. The utility model has the advantages of higher excursion detecting accuracy, minor environmental influence, long service life, simple structure, easy fabrication, lower production cost and convenient maintenance, which is not easy to damage.
Description
The utility model relates to a kind of printer, especially a kind of printer with detection paper shifting out function.
Along with development of computer, printer has also obtained popularization and application.General printer can have various promptings or treatment measures after faults such as scarce paper or paperboard take place.It is to rely on paper empty sensor set on the body paper-feeding passage, insert paper sensor and send corresponding signal.The basic structure of this paper empty sensor, slotting paper sensor as shown in Figure 5.Sensor is fixed on paper feed platform 2 belows on printer 1 body by fixed screw, stretches out the preformed hole of convex arm (as shown in the figure) from paper feed platform 2 of PE1, PE2 front end.During no print media, photo-coupler is by the blocking-up of the rear end of PE1, PE2, and sensor is in no paper state; When print media entered printer, medium can be depressed PE2, PE1 front end successively, because the effect of lever, lift PE2, PE1 rear end, and corresponding photo-coupler 3,4,5 is communicated with, and at this moment, sensor just is triggered.If but when paper feeding, not contraposition exactly of the placement of paper is very easy to occur skew.The consequence of the skew of paper feeding is or the file that prints can't use, or causes paperboard, even damages the first-class equipment of printing.Therefore for printer, analyzing always is an indispensable function.At the traditional method of printer industry is to adopt reflective or transmission-type analyzing mode, utilizes photoelectrical coupler to detect whether deflection of paper.Though this analyzing mode is widely used, its shortcoming also is well-known.At first, directly utilize the photoelectrical coupler analyzing to improve greatly and realize cost that this function consumes; Secondly, because photoelectrical coupler belongs to high precision components, it is very big therefore to be affected by the external environment, and especially dust can influence the analyzing function to a great extent; Once more,, make related circuit become complicated, be unfavorable for design and application owing to application to photoelectrical coupler.
The purpose of this utility model is to provide a kind of printer that detects the paper shifting out function that has, and it has overcome above-mentioned shortcoming effectively, and not only simple in structure, cost is lower, and improves the analyzing reliable in action of printer greatly.
The purpose of this utility model is achieved in that a kind of printer that detects the paper shifting out function that has, and comprises paper empty sensor set on printer body and the body paper-feeding passage, inserts paper sensor.The printer paper-feeding passage is provided with the analyzing sensor that certain distance is arranged with paper empty sensor horizontal direction, and the output of analyzing sensor meets the CPU of printer control circuit.
The position that is provided with of described analyzing sensor can be parallel with the paper empty sensor.
Described analyzing sensor construction is consistent with the paper empty sensor, can be press-contacting type.
Described analyzing sensor has with structure between the printer body also can be consistent with the mounting structure of paper empty sensor and printer body.
According to the technique scheme analysis as can be known, the utlity model has following advantage:
1, increased the analyzing sensor, can carry out analyzing automatically, avoided printing deflection and because of the partially frequent paper feeding of paper.
2, analyzing precision is higher, and affected by environment less, and is not fragile, long service life.
3, simple in structure, easy to manufacture, production cost is lower, and is easy to maintenance.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is provided with position view for the utility model analyzing sensor;
Fig. 2 is one of a kind of paper shifting out view of the utility model;
Fig. 3 is two of the another kind of paper shifting out view of the utility model;
Fig. 4 is the circuit theory diagrams of the utility model sensor and CPU coupling part;
Fig. 5 is the utility model sensor construction synoptic diagram;
Fig. 6 is the utility model one-piece construction intention.
Shown in Fig. 1,6, the utility model is a kind of printer 1 that detects the paper shifting out function that has.This printer 1 paper-feeding passage 2 is provided with and has three inspection paper sensors: paper empty sensor PE1, slotting paper sensor PE2, analyzing sensor PE3.Wherein, PE1 and PE2 are in vertical position, and PE1 and PE3 horizontal direction have certain distance, preferably are in parallel position.As shown in Figure 4, the output of paper empty sensor PE1, slotting paper sensor PE2, analyzing sensor PE3 all connects the CPU mouth line of printer control circuit.In the present embodiment, CPU can adopt TLCS-90 series.Paper empty sensor PE1, slotting paper sensor PE2, analyzing sensor PE3 connect P31, P53, the P54 mouth line (sometimes, the output of each sensor also can meet CPU again by gate-array circuit) of this CPU respectively.Other mouthfuls of CPU line and other control circuits be connected with consistent with prior art.When CPU lacks paper when appearance, paper empty sensor PE1 trigger pip, CPU sends the cue of corresponding paper empty; When inserting paper, insert paper sensor PE2 trigger pip, CPU sends the motion action behind the paper; When inserting the paper biasing, analyzing sensor PE3 trigger pip, CPU sends the paper number of believing one side only, and can will not place proper paper by original driving paper feed wheel topworks simultaneously and withdraw from.
Analyzing sensor PE3 structure of the present utility model is consistent with paper empty sensor PE1 in the prior art, can be press-contacting type, and analyzing sensor PE3 have with structure between printer 1 body also can be also consistent with the mounting structure and the working mechanism of paper empty sensor PE1 and printer 1 body.Therefore relevant concrete structure does not repeat them here.
When paper feed, if paper is parallel, then PE1 and PE3 are triggered simultaneously; If the paper deflection, then PE1 and PE3 are triggered priority, according to the state of PE1 and PE3 and the time interval that is triggered, can judge whether the inclined to one side and deflection of paper.
Being implemented as follows of analyzing function:
1, after the start, printer is waited for paper feed under no paper situation.
2, under friction paper feed mode during paper feeding, the paper front end triggers PE2 earlier, and this moment, printer detected the state of PE2 voluntarily, determined " paper is arranged ".
3, printer is judged and self is set before carrying out paper feed, examine paper? if inspection paper then begins paper feeding forward, detect the state of PE1 and PE3 simultaneously.
4, after PE1 or PE3 are at first triggered, then pick up counting, be not triggered as if another sensor certain hour " Time " (this time can be set) in, then paper feeding makes mistakes.Promptly determine to send into whether deflection of paper by the parallel position of PE1 and PE3.
As shown in Figure 2, in this mistake, PE3 is triggered earlier, constantly detects PE1 in timer S timing, if detecting PE1 in time T ime is triggered, and then paper feed success; PE1 is not triggered greater than Time as if S, then the paper feed mistake.
As shown in Figure 3, in this mistake, PE1 is triggered earlier, constantly detects PE3 in timer S timing, if detecting PE3 in time T ime is triggered, and then paper feed success; PE3 is not triggered greater than Time as if S, then the paper feed mistake.
