Description:
FIELD OF THE INVENTION 
     The present invention is related to an optical lens, particularly to a disposable lens applied to electronic operation device for recognition with portability and low cost. 
     BACKGROUND OF THE INVENTION 
     The conventional optical image expansion instrument applied to image expansion and then recognition is allowed for magnifying the image of a recognized unit through a microscope or a lens, followed by recognizing the recognized unit. Presently, the microscope or lens of the optical image expansion instrument sold on the market is manufactured by molding. Besides, other connecting components are more precise and complicated. As such, the manufacturing process is more overelaborate and production time is longer for the optical image expansion instrument, resulting in slightly higher cost of the optical image expansion instrument further. 
     In addition, the optical image expansion instrument is carried outdoors by the user inconveniently due to unduly large whole volume normally. Hence, there is a drawback of incapability to recognize the recognized unit immediately. To solve the problem of non-portability, the recognized unit is sampled and then preserved sealingly by the user. Afterwards, the recognized unit is recognized by the optical image expansion instrument indoors. 
     However, during sealing process and transportation process, the recognized unit may be affected by external environmental factors, such as sunlight irradiation, such that initial parameters of the recognized unit are changed. Probably, it is incapable of determining the authenticity of the recognized unit effectively and correctly, because the most authentic and correct data could not be obtained by the user. 
     Accordingly, there are a drawback of slightly higher cost due to complicated manufacturing process and a drawback of incapability to recognize the recognized unit immediately due to unduly large whole volume inherent in the conventional optical image expansion instrument. Consequently, the improvements should be required. 
     SUMMARY OF THE INVENTION

     On the basis of the above-mentioned object, the present invention provides a disposable lens applied to electronic operation device for recognition, comprising a substrate, a lens and a fix adhesive. The lens is provided at one end of the substrate and corresponded to an image-capturing unit of an electronic operation device. The fix adhesive is connected with one side of the substrate, so as to fix the substrate to the electronic operation device. 
     The features of the present invention are as follows.
         1. The disposable lens of the present invention is constructed simply, so as to provide the effect of compactness with portability, enabling the user to recognize the recognized unit immediately.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIGS. 1 to 3 , there is shown a disposable lens applied to electronic operation device for recognition provided by the present invention. An assembled structure, combining a disposable lens  2  onto an electronic operation device  1  including an image-capturing unit  10 , of the present invention may be used for the recognition of a recognized unit  3 . The disposable lens  2  includes a substrate  20 , a lens  21  and a fix adhesive  22 . The lens  21  is provided at one end of the substrate  20 , and corresponded to the image-capturing unit  10  of the electronic operation device  1 . The fix adhesive  22  is connected with one side of the substrate  20 , so as to fix the substrate  20  to the electronic operation device  1 . 
     In one embodiment of the present invention, the lens  21  is provided at one side of the substrate  20  and aligned with the image-capturing unit  10 , in such a way that the substrate  20  is provided between the image-capturing unit  10  and the lens  21 . The exemplary embodiment will not limit the present invention, only if the recognized unit  3  may be aligned with the image-capturing unit  10  through the lens  21  such that the image of the recognized unit  3  displayed on a display unit  11  of the electronic operation device  1  is expanded. The image-capturing unit  10  may be implemented as a front-facing camera lens of the electronic operation device  1 , or a rear-facing camera lens of the electronic operation device  1  illustrated in  FIG. 7 . Moreover, the substrate  20  in this present invention may be selectively implemented by a translucent or transparent plastic sheet, while the lens  21  may be selectively implemented by a cured polymer selected from epoxy resin, ultraviolet-cured adhesive, thermoplastic material and etc., so as to obtain the effect of low lost and mass-producibility. 
     Then, the disposable lens  2  of the present invention is constructed simply, so as to provide the effect of compactness with portability, and then to be manipulated by the user conveniently at any time or in one-handed operation to recognize the recognized unit  3 . Thereby, the drawback of bulkiness with non-portability resulting in incapability of instantaneous recognition of the conventional instrument is eliminated. The present invention is relatively advantageous in volume, convenience and cost. In the embodiment of the present invention, furthermore, the electronic operation device  1  may be implemented as a smart mobile device held by hand while provided with the image-capturing lens and operation function, and also possibly adapted to be the electronic operation device, such as a notebook  6  illustrated in  FIG. 8  and the tablet computer, e.g., iPad, for example. 
     Subsequently, referring to  FIGS. 4 to 6 , the recognized unit  3  may be implemented as a biochemical sheet  4  or an anti-forgery structure  5  in the practical use. In  FIG. 4 , firstly, one embodiment of the biochemical sheet  4  is described. The biochemical sheet  4  includes a test area  40  at one end of the biochemical sheet  4 , and a calibration area  41  located at the one end of the biochemical sheet  4  and adjoined to the test area  40 . During operation, a specimen to be identified is firstly added to the test area  40  of the biochemical sheet  4 , such that the specimen to be identified is mixed with a biochemical reactant on the test area  40 . Subsequently, the test area  40  and the calibration area  41  of the biochemical sheet  4  are aligned with the lens  21 . For the test area  40  and the calibration area  41 , therefore, the resulted test area  40  and the calibration area  41  are scanned by the image-capturing unit  10  and the image thereof is expanded through the lens  21  and the image-capturing unit  10 . After that, the expanded image is displayed on the display unit  11 . The comparison is then made by the user on the basis of difference between the magnified resulted test area and calibration area  41 . The biochemical reactant on the test area  40  of the present invention may be implemented as metal contents or pH value of environment pollutants, or analyte (such as glucose, cholesterol, ketone body and specific proteins, for example) in biofluid, such as blood, urine and saliva, for example, of human body. 
     Next, to be more precisely, the calibration area  41  further includes at least one comparison object (not illustrated in figures). This comparison object is comparison data inserted into the calibration area  41  previously in accordance with the type of the specimen to be identified. Particularly, data, such as the corresponding comparison value or table, is inserted into the calibration area  41  as the standard for comparison, when the biochemical sheet  4  is desired to inspect environmental metal contents or pH value. Furthermore, the corresponding comparison data is similarly inserted into the calibration area  41  when physiological parameters, such as blood glucose in blood, urine and saliva, for example is inspected as desired, and so forth. 
     Referring to  FIG. 4  again, the difference in performance between the test area  40  and the calibration area  41  may be recognized manually, or recognized by application programs automatically. In one embodiment, the electronic operation device  1  includes an application program (not illustrated in figures) electrically connected to the image-capturing unit  10 , such that the comparison of difference between the resulted test area  40  and calibration area  41  may be determined by the application program automatically. The calibration may be even performed by the application program so as to enhance accuracy. The calibration area  41  further includes at least one focused target object (not illustrated in figures). The focused target object may be implemented as calibration object, such as thick/thin stripes, checks, object-positioning light sources, white balance and so on. In the electronic operation devices of different bands or models, the parameters, such as on-screen display, brightness, for example, or various settings for the image-capturing units (for instance, color temperature, white balance) are all not the same. Then, if non-autofocus mode is adopted for the image-capturing unit  10 , accuracy may be possibly varied when the biochemical sheet  4  is captured by the image-capturing unit  10 . Instead, the electronic operation device  1  may be allowed to control the image-capturing unit  10  to calibrate the biochemical sheet  4  through the application program through the provision of the focused target object. Thus, inspection accuracy may be raised. 
     Referring to  FIGS. 5 and 6  again, there are shown embodiments for describing anti-forgery recognition of the recognized unit  3 . When a product requiring anti-forgery identification is developed by a company, the anti-forgery structure  5  is adhered to the product, in such a way that authenticity of the product may be identified by the user on the basis of the anti-forgery structure  5  when the product is bought. The anti-forgery structure  5  includes a main body  50 , a transparent colloid  51  provided at one end of the main body  50 , and at least one micro-carving plate  52  provided within the transparent colloid  51 . The micro-carving plate  52  is provided thereon with patterns, characters or numbers to be recognized. The transparent colloid  51  of the anti-forgery structure  5  is aligned with the lens  21  by the user. For the micro-carving plate  52 , therefore, the micro-carving plate  52  is scanned by the image-capturing unit  10  and the image thereof is expanded through the lens  21  and the image-capturing unit  10 . After that, the expanded image is displayed on the display unit  11  to be used by the user to verify authenticity of the product on the basis of the resulted image. 
     In one embodiment, referring to  FIGS. 5 and 6  again, the micro-carving plate  52  may be replaced by a barcode. The anti-forgery structure  5  includes at least one one-dimensional barcode  53  or at least one two-dimensional barcode  54  implemented as quick response code (QR code). In the practical use, only selective one of or any combination of the micro-carving plate  52 , one-dimensional barcode  53  and two-dimensional barcode  54  may be used, and further, the combined use thereof is exemplified in the embodiment of the present invention. In the combination type, dual confirmation on whether the product is a counterfeit may be achieved. The one-dimensional barcode  53  or the two-dimensional barcode  54  may be provided in vicinity of the micro-carving plate  52 , or the micro-carving plate  52  may be provided in the one-dimensional barcode  53  or the two-dimensional barcode  54 . The micro-carving plate  52  in the embodiment of the present invention illustrated in  FIG. 5  is provided in the vicinity of the one-dimensional barcode  53 , while the micro-carving plate  52  in the embodiment of the present invention illustrated in  FIG. 6  is provided in the two-dimensional barcode  54 . 
     More specifically, the micro-carving plate  52 , the one-dimensional barcode  53  or the two-dimensional barcode  54  may be magnified by the image-capturing unit  10  to be recognized by the customer manually. Accurate determination on authenticity of the product may be achieved through multiple sets of anti-forgery objects. The application program may be even used for the automatic recognition of the micro-carving plate  52 , one-dimensional barcode  53  or two-dimensional barcode  54 , so as to reduce human error in determination. 
     In addition, the one-dimensional barcode  53  or the two-dimensional barcode  54  may be also used as authentication of the product. The anti-forgery structure  5  is scanned by the image-capturing unit  10  of the electronic operation device  1  after the product is purchased. Subsequently, data may be logged on the website by the user for the accreditation, registration or authorization of the product. If the accredited product is counterfeited by others afterwards, the customer purchasing the counterfeit and desiring for accreditation will be notified by the system that the product has been accredited, registered or authorized. The customer is then informed of the product being a counterfeit. 
     The advantage of lower cost is provided, due to simple structure of the disposable lens  2 . Therefore, in the application to practical products, the biochemical sheet  4  or the anti-forgery structure  5  may be sold together with the disposable lens  2  in a bundle by developing manufacturers. Perhaps, the biochemical sheet  4 , the anti-forgery structure  5  and the disposable lens  2  may be sold individually. The disposable lens  2  may be kept or discarded depending on the situation by the customer after recognition is completed. Different from the conventional optical image expansion instrument being bulky and hard to preserve, the disposable lens  2  is formed in a lightweight portable and thin shape with simple structure and low cost, without excessive conflict with preservation when it is used by the customer and without taking up much space when it is carried by the customer. As such, the customer may not be bothered in any case. Cost burden is also not resulted, even the disposable lens  2  is discarded. In the present invention, moreover, the fix adhesive  22  is provided to enable the customer to fix the disposable lens  2  to the electronic operation device  1  while align the lens  21  with the image-capturing unit  10  more conveniently and rapidly. Subsequently, the biochemical sheet  4  or the anti-forgery structure  5  are then recognized. Thereby, the effect of facilitating prerequisite is achieved. 
     Further, the electronic operation device  1  includes a database (not illustrated in figures) electrically connected to the application program. Thereby, the results calculated by the application program may be stored into the database for subsequent auxiliary applications, such as statistics, data analysis and connection to remote server, for example.
