Abstract
The utility model provides a black mark detecting device for the self-learning-type printer paper, comprising a central processing unit C P U (1) and a photoelectric sensor (4). The detecting device can be operated according to the software program P, and also comprises an erasable write memory (2). The detecting device can make a special transparent or reflectance black mark (6) collect the transparent or light-reflecting signal of the black mark through the circuit of the photoelectric sensor (4) connected with an A/D converter (3) and proceed exchanging and then be distinguished by entering into the C P U, and the testing threshold value of the new black mark can be determined and can be stored. The proceeding subsequent testing has the standard after passing the self learning, the false testing rate can be reduced, and the normal work of the mini-type printer can be ensured.
Description
Technical fieldThe utility model belongs to photoelectric detection system, belongs to the intelligent photoelectric detection system of mini-printer especially.
Background technologyIn the mini-printer, use narrow row web-like printing paper record print result.Described narrow row web-like printing paper often is printed on various fixing form, symbols commonly used, to reduce the printing amount of printer.The printable character of printer cooperates described print format and the complete output content of symbolic representation.These forms, symbol often are printed on the fixed position of web-like printing paper again, need printer to discern certain starting point and begin to print from this point, printed contents could be matched with described set form, symbol.Described starting point is represented with black mark usually.Therefore, microprinting must correctly detect black mark and promptly print starting point.Common black mark checkout gear is to set fixed test voltage threshold, and this black mark piece that just requires to be printed on the detected paper meets the certain quality standard, printing opacity or reflectance unanimity, and will be in strict accordance with the requirement printing of density, reflectivity.But the actual print product are difficult to ensure the quality of products, and cannot say for sure more between each printing paper manufacturer that especially card is consistent, and it is higher consequently to cause black mark to detect mortality.In the prior art,, have only each unit physical circuit of modification to come adaptability to solve to this black mark printing opacity or the inconsistent situation of reflectance.For example can change the threshold voltage that black mark detects by the value of adjusting resistance in the circuit.But this method needs manually test repeatedly and adjust, and marks the adjustment of all will starting shooting when inconsistent of printing opacity or reflectance to black whenever, does not meet the convention of electronic product user normal running; And carry out the interior maintenance operation of machine repeatedly and can cause extremely bad influence the client.After guarantee period, be difficult to more implement to adjust in the customers' place.
Summary of the inventionThe utility model is that the above-mentioned deficiency that overcomes prior art proposes a kind of intelligent photoelectric detection system, need not open cover and carry out the circuit adjustment, only need to receive black target printing opacity of described printing paper or heliogram by the photoelectric sensor circuit that joins with A/D converter, and change, send into CPU again and differentiate; As long as gather the signal of some, record maximum, minimum of a value wherein just can determine that new black mark detects threshold value and storage.Through after such self study, ensuing detection will greatly reduce false failure rate as standard, guarantees the operate as normal of mini-printer.And this operation can start and be finished automatically by this device by the client, thereby makes things convenient for the printing paper of user adaptation different printing quality manufacturer production, is convenient to applying of mini-printer.
The purpose of this utility model can be achieved like this:
Design, the black mark of a kind of self study type printing paper of manufacturing checkout gear comprise central processor CPU and photoelectric sensor; Especially this checkout gear moves by software program P, and comprises the two-way scratch pad memory that is connected with described CPU.
Brief Description Of Drawings
Fig. 1 is the electric theory diagram of the black mark of the utility model self study type printing paper checkout gear;
Fig. 2 is the circuit theory diagrams of the reflective embodiment of described checkout gear;
Fig. 3 is the flow chart of the software program P of described printing and checkout gear operation.
The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
The black mark of a kind of self study type printing paper checkout gear comprises central processor CPU 1 and photoelectric sensor 4; Especially this checkout gear moves by software program P, and comprises and the described CPU 1 two-way scratch pad memory that is connected 2.
Also comprise the analog-digital converter 3 that is connected with CPU 1 with described photoelectric sensor 4.This analog-digital converter 3 receives the detection signal of described photoelectric sensor 4, changes the back and transmits to CPU 1.
Usually among the embodiment, described photoelectric sensor 4 is reflective photoelectric sensors.The light emitting devices of this sensor and light receiving element are arranged on the same side of printing paper.
Among other embodiment, described photoelectric sensor 4 is transmission-type photoelectric sensors.Its light emitting devices and light receiving element are separately positioned on the both sides of printing paper.
Owing to need wipe easily and rewrite, described scratch pad memory 2 adopts electric erasable electrically alterable memory EEPROM.
In the practicality, the way circuit block diagram of this device is seen Fig. 1.
The operation principle that black mark detects self study is as follows:
Pass through circuit design, utilize the corresponding software P of CPU 1 operation, when the new printing paper of the big producer of service property (quality) difference, the program of operation self study earlier, the traction printing paper advances, and makes a plurality of black marks 6 through photoelectric sensor 4, measures the maximum and the minimum of a value of the optical signal of its transmission or reflection, determine that new black mark detects threshold value D, and be kept in the nonvolatile memory EEPROM 2.Like this, the threshold voltage adjustment that actual black mark detects needn't be opened cabinet adjustment resistance and just can be finished, and is extremely convenient.
In concrete the detection, CPU 1 will detected black mark detected value C compares with detection threshold value D in being stored in described scratch pad memory EEPROM 2, and is very convenient, easy to judge top of form, and improves to deceive to mark and be detected as power.
Circuit theory diagrams of the present utility model are seen Fig. 2.
