Embodiment
Be elaborated below in conjunction with the execution mode of accompanying drawing to the application.
Fig. 1 is the structural texture block diagram of portable scanning device proposed by the invention, and this device comprises a processor 1, comprises an automatic focus picture pick-up device 2, aperture adjusting device 3, one group of fluorescent tube 4, key board unit 5, data-interface 6, memory 7, power supply 8 at least; Processor 1 connected storage 7 is built system's operation platform jointly; Fluorescent tube 4 is connected with iris aperture regulator 3 with processor 1 respectively, is used for producing on irradiated file destination the aperture of high light; Iris aperture regulator 3 connection processing devices 1 are used to regulate size and the length-width ratio of described aperture on file destination, to confine shooting area; Automatic focus picture pick-up device 2 is connected with processor 1, is used to take described aperture, and stores photographing information into memory 7; Keyboard 5 is connected with processor 1, is used to obtain the command information that the user sends; Data-interface 6 is connected with processor 1, is used for data output and input; Power supply 8 is described scanning means power supply.
Fig. 2 is a syndeton schematic diagram of apparatus of the present invention, comprises circuit control main board 9, and circuit control main board 9 comprises the main circuit part of apparatus of the present invention; Data-interface 6 is finished the data output and input of apparatus of the present invention and miscellaneous equipment; The Push And Release of fluorescent tube switch 51 control fluorescent tubes is taken taking pictures of switch 52 control automatic focus picture pick-up devices, and aperture is regulated shape and the size that button 10 control fluorescent tubes 4 are radiated at the aperture that produces on the file destination, regulates its length-width ratio equidimension; The aperture that fluorescent tube 4 produces on file destination has very high brightness.
Fig. 3 lays and mobile schematic diagram for the fluorescent tube of apparatus of the present invention, fixed lamp tube 41 constitutes a complete integral body by three fluorescent tubes, along plane coordinates Y-axis vertical direction a fluorescent tube is set, along plane coordinates X-axis horizontal direction two parallel fluorescent tubes are set, these two parallel fluorescent tubes are connected with two end points of fluorescent tube of vertical direction, and fixed lamp tube 41 can be a U-shaped fluorescent tube; The automatic focus picture pick-up device is fixed in fixed lamp tube and the plane, mobile fluorescent tube place, between the fluorescent tube and mobile fluorescent tube of fixed lamp tube Y-axis vertical direction, is equal to two parallel fluorescent tube distances of fixed lamp tube X-direction; The light that fixed lamp tube 41 sends is the slightly outer certain angle partially in center with automatic focus picture pick-up device 2 camera lenses, and outer drift angle degree must be less than half of automatic focus picture pick-up device 2 angles of visual field; The light that mobile fluorescent tube 42 sends is the slightly outer certain angle partially in center with automatic focus picture pick-up device 2 camera lenses also, and outer drift angle degree must be less than half of the picture pick-up device angle of visual field.Designing outer drift angle degree is will guarantee apparatus of the present invention when close or wide file, and the aperture size that forms on file destination has significant change, guarantees that simultaneously the aperture that produces on file destination always can be photographed.
Fixed lamp tube 41 and mobile fluorescent tube 42 light-emitting window width generally are controlled at 0.5～5mm, to guarantee launching enough light, form clear and legible aperture on file destination.The aperture that forms on file destination is the rectangle aperture, is the length of rectangle aperture along plane coordinates x direction of principal axis, is the width of rectangle aperture along plane coordinates y direction of principal axis.Iris aperture regulator 3 main effects are to regulate the position of mobile fluorescent tube along the plane coordinates X-direction, promptly change the length of the common sealing rectangle aperture that forms of mobile fluorescent tube and fixed lamp tube, the telescopic baffle that non-light transmissive material of while is made shelters from the part fluorescent tube 43 along the plane coordinates X-direction that wouldn't need, iris aperture regulator 3 is subjected to aperture to regulate the regulation and control of button 10, shines like this in rectangle aperture lengths on the file destination and the ratio between the width and can be adjusted on a large scale.
Apparatus of the present invention substitute the shooting area that display screen is confined file destination with fluorescent tube, are taken by the automatic focus filming apparatus and confine the zone, and general graph text information is changed into electronic image information, coverage is extensive, accurately directly perceived, easy to use flexible, can carry.
