The invention relates to a negative film scanner capable of automatically and continuously feeding negative films, and the negative film scanner comprises a shell, a PCB (Printed Circuit Board), a backlight mechanism and a negative film rail, wherein the PCB is provided with a camera lens and a sensor; the shell is internally provided with a PCB bracket; the PCB provided with the camera lens and the sensor is fixed on the PCB bracket; the position of the backlight mechanism is corresponding to that of the camera lens; the negative film rail penetrates through the shell; and the negative film rail is provided with a light transmission hole corresponding to the camera lens. The negative film scanner is characterized by further comprising a negative film transmission device; the negative film transmission device comprises a step motor, a worm, a turbine knob and a photoelectric switch; the worm is fixed on the rotor of the step motor; the worm drives the turbine knob to rotate; the turbine knob is provided with negative film clamping teeth; the negative film clamping teeth are matched with the negative film rail; and the photoelectric switch judges the walking distance by detecting the hole on the negative film so that the rotation of the step motor can be controlled by the photoelectric switch.
Description
Technical field
The present invention relates to a kind of egative film is converted to the device of numerical data, relate in particular to a kind of negative film scanner that advances egative film automatically continuously.
Background technology
In early days, the mode of retaining video mainly contains film cameras, makes each family all keep a large amount of films, or by the photo that these film rinsings go out, no matter be film or photo, As time goes on all can wear out, and lose easily, preserve very inconvenient.Along with popularizing of digital electronic products such as computer and digital camera, increasing people need convert a large amount of films or photo to numerical data.
Present negative film scanner egative film by knob regulate can continuous sweep 3 rewind the film to whole, but because knob is a manual adjustments, and the position of egative film need be adjusted by estimating, expends time in and be difficult to its accuracy of control.
Present negative film scanner is controlled advancing of egative film with external knob manual operation, needs turning knob once more behind the intact egative film of every scanning, complex operation, and be difficult to control the position of egative film.
Summary of the invention
The present invention is directed to above-mentioned problems and correct, the present invention adopts stepper motor drive knob to replace manual adjustments.Adopt this structure only need start scanning switch and just can finish the scanning of just rewinding the film.
Concrete technical scheme is:
A kind of negative film scanner that advances egative film automatically continuously, it comprises housing, have the pcb board of phtographic lens and transducer, back-light mechanism and egative film track, the PCB support is arranged in the described housing, the described pcb board that has phtographic lens and transducer is fixed on the described PCB support, described back-light mechanism is corresponding with described phtographic lens position, described egative film track connects described housing, and described egative film track has loophole in described phtographic lens corresponding position; It is characterized in that: it also comprises the egative film transmission device, described egative film transmission device comprises stepper motor, worm screw, turbine knob and optoelectronic switch, described worm screw is fixed in the rotor of described stepper motor, described worm screw drives described turbine knob, described turbine knob has the egative film latch, described egative film latch cooperates with described egative film track, and the distance that it is passed by is judged in the hole on the described optoelectronic switch detecting egative film, thereby described optoelectronic switch is controlled the rotation of described stepper motor.
Described case top lid has a display screen, described display screen with have phtographic lens and be connected with the pcb board of transducer.
Described phtographic lens is a tight shot.
The present invention adopts stepper motor to drive worm screw and rotates, the worm gear knob drives the egative film straight line and travels forward under the gearing of worm screw, optoelectronic switch is judged the distance that it is passed by by the hole on the detecting egative film, thereby the rotation number of turns of control step motor, come accurately to control the position of egative film and the stall of every film scanning front and back stepper motor according to this, so just can finish whole scanning of rewinding the film.
The present invention adopts stepper motor to drive the egative film knob by worm and gear, control the stroke of its rotation by optoelectronic switch, come accurately to control the position of egative film according to this, when whole rewinding the film do not need manual rotary knob to control the egative film process when needing to scan, only need to start scanning switch and can realize whole scanning of rewinding the film.
Description of drawings
Fig. 1 is an embodiment of the invention schematic diagram.
