A kind of point reader
Technical field
The present invention relates to the electronic product field, relate in particular to a kind of point reader.
Background technology
Along with the development of information and electronics technology, auxiliary learning tool has obtained development at full speed, and point reader is the another generation study product after computer learning machine, language repeater, electronic dictionary.Point reader adopts contactless magnetic induction recognition technology, books or paper are put on the interval in the point reader housing, when the content on pen with means for holding it in right position contact books or the paper, the point reader main frame is according to the position that is distributed in the pen with means for holding it in right position that the identification point on the interval identifies, the data of storing described books or paper in advance (comprise content with relevant position etc.) is carried out relevant program, thereby read related content.
Fig. 1 is the structural representation of a kind of point reader in having now, Fig. 2 is the part enlarged drawing of Fig. 1, and Fig. 3 is a kind of outboard profile of opening the point reader of housing in having now, and Fig. 4 is the part enlarged drawing of Fig. 3, Fig. 5 is a kind of outboard profile of opening the point reader of housing in having now, and Fig. 6 is the part enlarged drawing of Fig. 5.
As depicted in figs. 1 and 2, the loam cake of point reader is connected by a connection piece with lower cover, at loam cake with cover down and close web member one side is not provided with detent mechanism, after opening housing, form the book-groove of the spine of placing books, its width is fixed, but the spine thickness difference of different books, therefore as shown in Figure 3 and Figure 4, the spine of books is offset in the book-groove of point reader, perhaps as shown in Figure 5 and Figure 6, the spine of books is deviate from from book-groove, cause that point reader is inaccurate to the books location, the content that causes point reader to read is not inconsistent with the bookish content that pen with means for holding it in right position contacts, and gives the guidance of user error.
Summary of the invention
In order to solve the problems of the technologies described above, the embodiment of the invention has proposed a kind of point reader, its housing comprises loam cake and lower cover, described loam cake is connected by a connection piece with described lower cover, form to place the book-groove of the spine of books, at described loam cake with cover down and be provided with the detent mechanism that at least one is used for fixing described books near described web member one side.
Wherein, described detent mechanism comprises a pair of locating device about described book-groove symmetry, described locating device comprises: torsion spring, axle and rotating clamp, described axle be fixed on described loam cake or under cover, described rotating clamp rotates around described axle, described torsion spring is wound on the described axle, and an end of described torsion spring contacts with described rotating clamp, and the other end contacts with described loam cake or described lower cover.
Preferably, described detent mechanism is separately positioned on the two ends of described book-groove.
Implement the embodiment of the invention, the problem that the spine that has solved books effectively skew takes place in the book-groove of point reader or deviates from from book-groove, detent mechanism is fixed on the point reader books, make the location of point reader more accurate, improve the accuracy of the content that point reader reads, satisfied user's demand.

Embodiment
The embodiment of the invention provides a kind of point reader, at the loam cake of close web member one side of described point reader with cover down and be provided with the detent mechanism that is used for fixing books.
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
At first see also Fig. 7 and Fig. 8, Fig. 7 shows the structural representation of a kind of point reader in the embodiment of the invention, Fig. 8 is the part enlarged drawing of Fig. 7, point reader is provided with the detent mechanism 74 that is used for fixing books near the loam cake 71 and the lower cover 72 of web member 75 1 sides, and detent mechanism 74 comprises locating device 76 and locating device 77.
Preferably, as shown in Figure 7, detent mechanism 74 can be separately positioned on the two ends near web member 75 1 sides, by two detent mechanisms 74, clamps the spine of books simultaneously, makes the location more accurate.
See also Fig. 9 and Figure 10, sectional view when Fig. 9 shows a kind of point reader in the embodiment of the invention and opens housing, Figure 10 is the part enlarged drawing of Fig. 9, the housing of described point reader comprises loam cake 71 and lower cover 72, loam cake 71 has a connection piece 75 to be connected with lower cover 72, form the book-groove 73 of placing the books spine, be provided with at least one detent mechanism that is used for fixing described books 74 on loam cake 71 and lower cover 72 and near web member 75 1 sides, detent mechanism 74 comprises a pair of locating device 76 and locating device 77 about book-groove 73 symmetries.
See also Figure 11, Figure 11 is the part enlarged drawing of Fig. 9, and detent mechanism 74 comprises a pair of locating device 76 and locating device 77 about book-groove 73 symmetries.
Wherein, locating device 76 comprises torsion spring 91, axle 92 and rotating clamp 93, axle 92 is fixed on the loam cake 71, rotating clamp 93 rotates around axle 92, torsion spring 91 is wound on the axle 92, and an end 91b of torsion spring 91 contacts with rotating clamp 93, and other end 91a contacts with loam cake 71, rotating clamp 93 is subjected to the restoring force of described torsion spring 91 in rotating process, thereby clamps the spine of books;
Locating device 77 is the same with locating device 76, comprise: torsion spring 91, axle 92 and rotating clamp 93, difference is, axle 92 is fixed on the lower cover 72, and rotating clamp 93 rotates around axle 92, and torsion spring 91 is wound on the axle 92, one end 91b of torsion spring 91 contacts with rotating clamp 93, other end 91a contacts with lower cover 72, and rotating clamp 93 is subjected to the restoring force of described torsion spring 91 in rotating process, thereby clamps the spine of books.
See also Figure 12 and Figure 13, sectional view when Figure 12 shows a kind of point reader in the embodiment of the invention and opens housing, Figure 13 is the part enlarged drawing of Figure 12, after opening the housing of point reader, the loam cake 71 of housing is connected by a connection piece 75 with the lower cover 72 of housing, and be formed for placing the book-groove of the spine of books, rotating clamp 93 can rotate the width of the book-groove of adjusting web member 75 tops that connect loam cake 71 and lower cover 72 by the direction of arrow among Figure 10, different-thickness with the spine that adapts to different books, and under the restoring force effect of torsion spring, clamp the spine of books, make books not take place to be offset and to deviate from book-groove, make the point reader location more accurate.
See also Figure 14 and Figure 15, sectional view when Figure 14 shows a kind of point reader in the embodiment of the invention and places books, Figure 15 is the part enlarged drawing of Figure 14, the spine of books 32 is placed in the book-groove of web member 75 tops that connect loam cake 71 and lower cover 72, rotating clamp 93 is clamped the spine of described books 32, thereby fixed books, prevented that books are offset and break away from from book-groove.
In sum, the embodiment of the invention is by at described loam cake with cover down and be provided with the detent mechanism that at least one is used for fixing described books near described web member one side, the problem that the spine that has solved books effectively skew takes place in the book-groove of point reader or deviates from from book-groove, make the location of point reader more accurate, improve the accuracy of the content that point reader reads, satisfied user's demand.
Above disclosed only is a kind of preferred embodiment in the embodiment of the invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of doing according to claim of the present invention still belongs to the scope that the present invention is contained.
