Technical field
This utility model is related to the visual field partition tools used in a kind of fast reading.
Background technology
The speed of reading depends on the size in the visual field, during reading, according to the size in the visual field, reading is divided three classes：Point type
Read, wire type is read and facial reading.It is minimum that point type reads the visual field, only one or two word, reading speed only have one minute it is hundreds of
Word；It is more than several words that wire type reads visual field size, and in the visual field, these words link in straight line, and visual field maximum can reach one
Style of writing word, now reading speed can reach more than one minute one or two K word；Facial reading visual field size is more than two style of writing words,
In a plane, reading speed can reach one minute several K word or higher to viewing field shape.
In fast reading, a most important link is to expand the visual field, has various training methodes, such as character training, figure
Training, Shu Ertebiao training etc..In these training programs, all demarcated to trainer with means such as lines, word quantity and regarded
Wild magnitude range.But, when trainer turns to the actual reading training to paper materials such as books, magazine, newpapers and periodicals, due to
Lack the complementary means for demarcating visual field border, many difficulties can be run into, such as trainer does not know the visual field size model of oneself
Enclose, the visual field used is suddenly big or suddenly small, the visual field has retraction to reduce tendency, and left and right adjacent fields boundary is unclear, segment word occurs to repeat
Intake etc..Fast reading, improves training effect for convenience, needs, by a kind of visual field partition tools, to realize to books etc.
The papery text of publication carries out visual field segmentation.Some for occurring at present read visual field dispenser, can reach object above, side
Fast reading, improve training effect.But the problem for existing is, when completing a page word read every time, need
To read after visual field dispenser is transposed to another page, and location confirmation well again and can just continue training；Or
During page turning, need reading visual field dispenser is taken down from books, book page is translated into into the next page with handss then, then will be read
Visual field dispenser places back in books, puts good position, and the visual field just then can be trained after splitting well.This process seems
Bother a little, so need to find a kind of solution route, after the completion of visual field size is disposably split, can continuously page turning, no
Need again to put again repeatedly visual field dispenser position and just the visual field can be split, so as to bring greatly just to fast reading

The content of the invention
This utility model provides a kind of reading visual field dispenser that can realize continuous page turning, solves the above-mentioned reading visual field
There is inconvenience when in use in dispenser.
This utility model has used for reference the functional design of the instruments such as optical lantern, projector, with reference to LED illumination skill popular at present
Art, is developed and the brand-new product of formation by transformation and again.This utility model is achieved through the following technical solutions to books class
The visual field segmentation of papery text：A kind of projection-type with LED as light source reads visual field dispenser, is divided into main frame, support, base several
Part, main frame are made up of shell, light source, condenser lenss, picture, projection lens, on and off switch, brightness regulating switch.Support and bottom
Seat can using at present with desk lamp analog structure, all kinds and style can be divided, need not be described in detail here.The effect of support and base
Can be adjustment main frame position so as to which light can be projected on read book pages, complete visual field segmentation.Main frame
Shell is cylindrical, can be made up of plastics or metal, if metal, then has thermolysis.Light source is arranged on main frame rear, light
The effect in source is that picture is illuminated, and makes the image for being formed is projected by picture and have enough brightness.Light source adopts LED type,
With power saving, high durable, brightness and compact structure, portable advantage.It is condenser lenss before light source, is convex lenss, it
Effect be the uniform light that sends light source be radiated on picture, and make by the light-ray condensing of picture to projection lens.It is poly-
It is picture before light microscopic, picture is arranged on a circular picture inframe, picture box diameter and enclosure mouth diameter are consistent, and longitudinal direction is inserted
In inside the shell.At picture box position, shell has the slit-shaped openings of one 90 ° of sizes, and picture box has raised, this projection
Just expose in slit-shaped openings, projection can be stirred in the range of 90 ° of size, such that it is able to change picture axial angle,
So as to change the direction of cut-off rule, as be originally cut-off rule be genesis analysis, cross direction profiles can be become.Picture box is stuck in outer
In shell, can only stir, it is impossible to take out, this has protective effect to picture.Picture is that, by circular non-opaque card, material can be glass
Or plastics, the equal lines of the spacing that is parallel to each other, i.e. visual field cut-off rule are decorated with above.Cut-off rule can be colourless, line for background
It is colourless or bright colored two types that body is black or colour, or background for black, wire body.It is projection lens before picture,
Its effect is the inverted image that projection produces a clear bright picture for being exaggerated a lot of times.Projection lens can be pushed away in front and back
Move, can so change the distance between camera lens and picture, the size, definition and image such that it is able to adjust into image and
Camera lens apart from the problems such as.In order to make more adapting to use environment of the present utility model, projection lens adopts zoom lens, can
With continuous vari-focus.Because image size conversion advises using high-power zoom lens than larger.By the change of zoom lens
Jiao, can be to realizing the control of image size.In addition, the on and off switch arranged on main frame is used for control main frame power supply Push And Release,
Brightness regulating switch can adjust the brightness size for reading the image that visual field dispenser casts out in the way of knob.Main frame
Power-supplying forms can be that city residents' energy consumption or battery are powered, and battery can be divided into common batteries and button cell again.
When using this reading visual field dispenser, can first open the book, books are placed on into correct position, is then opened
Visual field segmentation appliance mains switch is read, makes projection lens have light to cast out, appearance is put by adjusting position base, support
State, makes books of the image that projection lens casts out just to launching.Then, position and the focal length of projection lens, control are adjusted
The image size for casting out.As the image for casting out is cut-off rule, when image is big, segmentation distance between centers of tracks is also big；Image is little
When, segmentation distance between centers of tracks is also little；Further, since the segmentation distance between centers of tracks on picture is equal, the cut-off rule of image is in positive projection time
Away from also equal.So, we can be by controlling the size of image come the visual field size required for obtaining, so as to complete to books
The visual field segmentation of page word.
It is noted that Railway Project be：The word of book page is read the cut-off rule covering that visual field dispenser is projected,
And still with the presence of cut-off rule image outside books, the image of this portion of residual we do not spend reason it.Due to books or so page two
There is gap length between word, its spacing will not be equal to the between word spacing of books text composition, so using the reading visual field point
During cutter, the recto beginning visual field size that is divided to form of avris is likely to result in different with our demand.Equally, press at us
According to oneself need visual field segmentation carried out to books verso beginning avris, but on the right of the verso last visual field of side text
Number of words may be with our required visual field cause not of uniform size, and such as book page type-setting mode is 26 word × 26 rows, our visual field
Size is 7 words, after word is by visual field segmentation so verso is often composed a piece of writing, forms this state of/7 word/7 word/7 word/5 words, last
Visual field size and other parts are inconsistent.In addition, last visual field of side also occurs analogue on the right of recto.Although such as
This, but due to split distance between centers of tracks it is equal, the equal size in most of visual field of split formation, thus on training effect impact be not
It is too big.
During online reading, it would be desirable to cut-off rule projection line be longitudinal arrangement, and during facial reading, it would be desirable to
Cut-off rule projection line be transversely arranged, as long as the angle of our switches once picture just can be adjusted with cut-off rule direction
Come.
As the image for projecting has dividing for size, cause the intensity of unit area glazing different, have sight equation, at this moment
Us are waited by brightness regulating switch to make up this gap.In addition, daytime using and evening using also there is difference, at this time I
Also by brightness regulating switch making up this difference.The brightness of adjustment image is using Jing during this reading visual field dispenser
The problem for often facing, when reading, the light source for reading visual field dispenser need not be adjusted very bright by we, as long as typically allowing books
It is upper to obtain slight cut-off rule image and to use, and can go to change the light sensation of around visual field, it is allowed to and either with or without with regarding
Wild dispenser does not have too big difference, is so conducive to protecting vision.
From the above mentioned, this projection-type with LED as light source is read when visual field dispenser solves fast reading really such as
