The said resolution that attendes projector, left projector, right projector is identical;
The said projector of attending is installed on writing paper top, and and the normal of writing paper between angle be 30 degree, the said camera lens of attending projector is from axle 30 degree, throw light downward bias 45 is spent and is incident to writing paper;
Said left projector is installed on the writing paper upper left side, and and the normal of writing paper between angle be 45 degree, the camera lens of said left projector is from axle 45 degree, throw light is incident to writing paper to inclined to one side 45 degree in bottom right;
Said right projector is installed on the writing paper upper right side, and and the normal of writing paper between angle be 45 degree, the camera lens of said right projector is from axle 45 degree, inclined to one side down left 45 degree of throw light are incident to writing paper.
Orthogonal projection device provided by the invention is according to the principle of learning to write by tracing over characters printed in red, and ins conjunction with the optical projection system of projector, projects and wants the copybook copied, need not to prepare separately copybook, also can when practising, not block light path and influences exercise, and is easy to use and be full of interest.
Description of drawings
Fig. 1 is the structure principle chart that is used for the orthogonal projection device that copybook copies that the embodiment of the invention provides.
Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention combines orthogonal projection technological according to the principle of learning to write by tracing over characters printed in red, and projects to want the copybook copied, a kind of instrument that carries out learning calligraphy and creation.The break traditions limitation of copybook of present embodiment, residence is learned in pleasure, is applicable to that the old man copies calligraphy, and children's calligraphy is popularized and drawing is popularized, and better passes on the Chinese traditional calligraphy culture.
Fig. 1 shows that the embodiment of the invention provides is used for the structural principle of the orthogonal projection device that copybook copies, and for the ease of describing, only shows the part relevant with present embodiment.
With reference to Fig. 1; The embodiment of the invention provides is used for the orthogonal projection device that copybook copies and comprises: signal source system 1, input-output unit 2, attend projector 3, left projector 4, right projector 5; Wherein signal source system 1 is used to export copybook information; It comprises light source, copybook image-generating unit successively along optical path direction, is built-in with character library and/or picture library in the copybook image-generating unit.This character library comprises all fonts of Chinese calligraphy's Chinese character, is equivalent to electronic copybook on the function, and the font that positive pen is write all has the text grid to do reference; Creative copybook reference is also arranged, be similar to the calligraphic copying works, picture library (like simple picture) part is primarily aimed at juvenile or pupil's design; Purpose is for cultivating student's Writing-painting ability; The pupil who begins to learn to write can write through correct aiming drill, forms good writing style, improves the calligraphy level.
In the present embodiment, signal source system 1 is connected with last projector 3, left projector 4, right projector 5 through an input-output unit 2, and this input-output unit 2 has an input port and three delivery outlets at least, as adopts one to advance three USB interfaces that go out.Certainly, also can dispense input-output unit 2, directly will go up projector 3, left projector 4, right projector 5 and be connected with signal source system 1.
Utilization optical projection copybook; Be easy to block the light that projector sends when writing; And then have influence on Writer's exercise; Therefore for avoiding when the exercise Writer's hand or other positions to block the light path of projector, require to attend projector 3, left projector 4, the view field of right projector 5 on writing paper 6 and overlap fully.As one embodiment of the present of invention; Through but be not limited to following mode and reach above-mentioned effect: attend projector 3 and be installed on the writing paper top; And and the angle between the normal of writing paper 6 is 30 degree, and the camera lens of last projector 3 is from axle 30 degree, and throw light downward bias 45 is spent and is incident to writing paper 6; Left side projector 4 is installed on writing paper 6 upper left sides, and and the normal of writing paper 6 between angle be 45 degree, the camera lens of left projector 4 is from axle 45 degree, throw light is incident to writing paper 6 to inclined to one side 45 degree in bottom right; Right projector 5 is installed on writing paper 6 upper right side, and and the normal of writing paper 6 between angle be 45 degree, the camera lens of right projector 5 is from axle 45 degree, inclined to one side down left 45 degree of throw light are incident to writing paper 6.
Further, last projector 3, left projector 4, right projector 5 average level directions are installed, and resolution is identical, and are consistent to guarantee drop shadow effect.
Further, the storer (not shown) that can also in the orthogonal projection device, increase a camera system or scanning system and be connected with camera system or scanning system, the works of finishing writing can be preserved into the electronics shelves through taking pictures or scanning.Further, can also set up a network interface, this network interface is connected with camera system or scanning system, with take pictures or scan after works upload and share the orthogonal projection device on the network.
Further, also built-in a dozen subsystems of above-mentioned orthogonal projection device are given a mark for Writer's works after exercise finishes, and strengthen interesting.
Compare with the tradition copybook of learning to write by tracing over characters printed in red, the orthogonal projection device that the embodiment of the invention provides has following advantage:
1, through adjustment optical axis and polarizing angle, the image that 3 diverse location projectors are launched overlaps fully.
2, adopt novel micro projection technology, reduced the volume of equipment, conserve space, easy to use with carry.
3,, in the time of the same picture of the projection of the projector of 3 diverse locations, solved the shadow problem of each angle through adjustment optical axis and polarizing angle.
4, the non-paper spare form of copybook is economized on paper, the protection environment.
5, adopt low lumen projection machine, the protection eyes.
6, the diversity of copybook can not be confined to a kind of font, can be according to the hobby of oneself, and the corresponding font of projection is depicted study.
7, be applicable to that the old man copies hobby, and children's calligraphy is popularized and drawing is popularized, and better passes on Chinese calligraphy's culture.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
