Description

Scanner

Technical field

The present invention relates to a kind of scanner, particularly relate to a kind of scanner that can discern positive and negative film.

Background technology

Scanner on the market provides the function of scanning positive and negative film gradually at present, and because positive is different with the video picture mechanism of negative film, therefore, before the scanning contribution, it is positive or negative film that the user must choose the contribution that will scan from the computer setting.But because the required setting of doing is various in scanning process, user Chang Keneng ignores this option and the setting that makes the mistake.And, therefore, waste many times after complete scanning if setting mistake then can only can correct because scanning scanning positive or negative film need come imaging with the accumulation light quantity the more time for exposure.

Summary of the invention

A kind of scanner that the present invention provides in order to solve above-mentioned prior art problem, it has a light shield, a copy hold and a controller.Light shield has a transducer, is located at the light shield surface.Copy hold has an identification part, is located at the copy hold surface.Transducer can detect the identification part, and send a sensing signal to controller, controller can be judged the kind of this scanning contribution by sensing signal, and the driven sweep device scans this scanning contribution with correct scan pattern, wherein, this transducer comprises one first sensing member and one second sensing member, is located on this transducer, this first sensing member and this second sensing member can transmit one first signal or a secondary signal to this controller according to the situation of this identification part.

The present invention also provides a kind of scanner, can judge the kind of one scan contribution, comprising: a cover plate, have a transducer, and be located at this lid surface; One copy hold should scanning contribution with clamping, and this copy hold has an identification part, is located at this copy hold surface, and when scanning this scanning contribution, this transducer can detect this identification part, and sends a sensing signal on this cover plate is placed on this copy hold; An and controller, accept this sensing signal to judge the kind of this scanning contribution, and drive this scanner and scan this scanning contribution with correct scan pattern, wherein, this transducer comprises one first sensing member and one second sensing member, be located on this transducer, this first sensing member and this second sensing member can transmit one first signal or a secondary signal to this controller according to the situation of this identification part.

Use the present invention, the user does not need to do extra contribution kind and selects to set, and scanner can detect the contribution kind automatically and make correct setting.So can save the time of setting scan pattern, and can reduce and set wrong chance.

Embodiment

With reference to Fig. 1 a, it shows scanner of the present invention, and it has one scan device main body 110, a light shield 120, a copy hold 130.Scanner main body 110 has a controller (not graphic), is located among the scanner main body 110, on the scanner main body 110 and be provided with location mark 111 and a cover plate 112.Copy hold 130 is used for clamping egative film (positive or negative film), which is provided with positive folder 131,1 first location structure 132, a negative folder 133, one second location structure 134, one first identification part 135 and one second identification part 136.Light shield 120 is in order to being placed on the copy hold 130, preventing leakage of light when the scanning egative film, and detects the kind of scanning contribution simultaneously.

With reference to Fig. 1 b, when the scanning egative film, copy hold 130 is placed according to alignment mark 111 specified corners.120 of light shields are placed in scanning position on the copy hold 130 according to first location structure 132 or second location structure 134.

Fig. 2 shows the detailed structure of copy hold 130, and copy hold 130 is a slab construction, and positive folder 131 has a hole 1311 that runs through this copy hold upper and lower surface, for putting positive.Has first location structure 132 around the positive folder 131, so that light shield 120 is restricted to one first scanning position when the scanning positive.It is other that this positive folder 131 is located in first identification part 135.Negative folder 133 has a hole 1331 and a chute 1332 that runs through this copy hold upper and lower surface, for putting negative film.Has second location structure 134 around the negative folder 133, so that light shield 120 is restricted to one second scanning position when the scanning negative film.It is other that this negative folder 133 is located in second identification part 136.

Fig. 3 shows the detailed structure of light shield 120 bottoms, and it is provided with location structure 121 and transducer 122.Transducer has one first sensing member 1221 and one second sensing member 1222.In the time of on light shield 120 places copy hold 130, transducer 122 utilizes first sensing member 1221 and second sensing member 1222 to detect

identification part

135 or 136, and send one first sensing signal or one second sensing signal to aforesaid controller, controller is judged the kind that scans contribution according to this first sensing signal and one second sensing signal, and the driven sweep device scans this scanning contribution with correct scan pattern.Transducer 122 can be made up of the switch (sensing member) of press-contacting type, also can be the transducer of other pattern, as optical sensor.The identification part can be for pressing the convex structure of touching transducer 122, also can be for the structure of Gong the identification of other form, as Christmas tree pattern.

With reference to Fig. 4 a, it shows the detailed structure of transducer 122, and first sensing member 1221 and second sensing member 1222 are the press-contacting type switch, are positioned at transducer 122 bottoms, transducer also has signal output port 1223, to export first sensing signal and one second sensing signal.Above-mentioned structure, except that first sensing member 1221 and second sensing member 1222, remaining structure all is embedded among the light shield 120.With reference to Fig. 4 b, when the scanning positive, transducer 122 is pressed the convex structure 1351 of touching 135, the first identification parts, first identification part to press and is touched first sensing member 1221, therefore transducer 122 transmits one first sensing signal to controller, and the scanning contribution that hence one can see that at this moment is a positive.With reference to Fig. 4 c, when the scanning negative film, transducer 122 is pressed the convex structure 1361 of touching 136, the second identification parts, second identification part to press and is touched second sensing member 1222, therefore transducer 122 transmits one second sensing signal to controller, and the scanning contribution that hence one can see that at this moment is a negative film.When the situation that first sensing member 1221 and second sensing member 1222 are not all touched by pressure, then controller is judged to be general reflection contribution with contribution.

Above-mentioned scanner is for utilizing the form of light shield 120 shield lights when scanning egative film.Yet the cover plate 112 that utilizes scanner merely if do not use light shield 120 is shield lights when the scanning egative film, and the scanner of this kind pattern also can be discerned contribution under spirit of the present invention.It can be arranged at transducer the ad-hoc location of cover plate 112, when cover plate 112 covers following time, the identification part on the copy hold 130 is detected, thus the kind of judgement contribution.And the contribution of desire identification also not only is defined in positive or negative film, and it also can be the contribution of other pattern.Again, positive folder and negative folder also can be located at respectively on the different copy holds.

Though disclosed the present invention in conjunction with above preferred embodiment; yet it is not in order to qualification the present invention, any skilled personnel, without departing from the spirit and scope of the present invention; still can do some and change and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined.
