For example, if the text is about an animal, the button 12 may be for turning the speaker 13 into a rabbit, an elephant, a lion's cry, or a page-by-animal story.

In the case of the conventional smart book stage, the stage and the teaching material are fixedly coupled and have a one-to-one coupling relationship. In this case, there is a disadvantage that the stage can not be used efficiently.

2 is a diagram for explaining a smart book stage according to an embodiment of the present invention.

The smart book stage according to an embodiment of the present invention may include a book stage 200 and a media interface unit 300.

The book stage 200 may include a cover 1, a back cover 2, a side cover 3, and a slide engagement slit 7.

At this time, the slidable engagement slit 7 may be formed on the side cover 3.

3B, the slide engaging slit 7 has a slit bottom 73, a pair of lateral wings 74 formed at both edges of the slit bottom 73, and a lateral wing 74, Prevention blades 71 extending in the direction opposite to each other and formed to be parallel to the slit bottom portion 73. [ At this time, the coupling bundle holder portion 72 can be formed through the pair of the separation preventing blades 71, the slit bottom portion 73, and the pair of side wing portions 74.

On the rear cover 2 of the book stage 200, the media interface unit 300 can be detachably coupled.

The media interface unit 300 may include a processing unit, a user input unit (e.g., a button), a speaker, a communication unit, and a battery. The basic configuration of the media interface unit 300 may be the same as that of FIG.

A memory slot 310 may be formed in the media interface unit 300 and a memory 311 may be inserted through the memory slot 310.

The teaching material 100 can be slidingly coupled to the coupling unit holder 72 of the slide combining slit 7.

At this time, the teaching material section 100 may include an exchangeable book, and a slide combination bundle 8. [ And the exchangeable book may comprise a plurality of bookcases and a binder (or binding part) of silicon component. The binder may bind one edge of the plurality of bookcases to each other. And the slide coupling bundle 8 may be coupled to the binder.

The optimum length of the longitudinal edge L of the bookstage may be L1 and the optimal length of each corner of the book and the slide combination bundle 8 disposed in a direction parallel to the edge L may be determined by the edge Lt; RTI ID = 0.0 > L1. ≪ / RTI >

FIG. 3A is a bottom perspective view of a slide coupling bundle 8 according to an embodiment of the present invention, FIG. 3B is a partially cutaway perspective view of a slide coupling slit 7 according to an embodiment of the present invention, FIG. FIG. 3D is a bottom perspective view of a slide combining slit 7 according to one embodiment of the present invention, and FIG. 3D shows a portion of a book stage 200 and a media interface according to an embodiment of the present invention.

Hereinafter, FIGS. 3A to 3D will be described together.

A memory slit 810 may be formed on a side surface of the slide coupling bundle 8. A memory connection terminal 831 may be formed at the bottom of the slide coupling bundle 8. The memory connection terminal 831 may be electrically connected to the terminals formed on the memory slit 810.

A memory connection terminal 731 may be formed in the slit bottom portion 73 of the slide combining slit 7. The memory connection terminal 731 may be coupled to the memory connection terminal 831.

 A first metal pad 231 may be formed on the side cover 3 of the book stage 200. And a second metal pad 251 may be formed on the rear cover 2 of the drum stage 200. The first metal pad 231 and the second metal pad 251 may be electrically connected through a lead. At this time, in one embodiment of the present invention, the 'metal pad' may be 'one or more electrodes'.

The second metal pad 251 may be coupled to the connection terminal 320 formed at the bottom of the media interface unit 300.

That is, the memory slot 810 and the connection terminal formed at the bottom of the media interface unit 300 may be electrically connected through the memory connection terminals 731 and 831 and the metal pads 231 and 251. Therefore, when the media interface unit 300 wants to listen to the media voice by pressing a specific button, the media interface unit 300 can access the memory of the slide combination bundle 8 to output the media voice corresponding to the specific button .

4 is a view for explaining a coupling relation with the slide engagement slit 7 along the length of the book according to an embodiment of the present invention.

4 (a) is a view for comparing different books (= exchange books) having different lengths, and FIG. 4 (b) is a view for comparing different lengths of the books when the vertical length of the book is L2 And the slide coupling bundles 8 having the same shape are combined with each other.

In general, the shape and size of books can vary. For example, it can be assumed that the vertical length of the optimized first book is L1. At this time, in the case of the second book having the vertical length L2 (L2 <L1), when the second book is fixedly coupled to the slide binding bundle 8 having the optimized vertical length L1, The vertical portion of the bundle 8 is left by the difference of L1-L2. In this case, the appearance is awkward and the cost of L1-L2 can be wasted. Therefore, when the vertical length of the book is different from the optimized vertical length L1 as in the second book, it is reasonable to combine the slide combination bundle having the vertical length (L2) equal to the vertical length (for example, L2) .

At this time, as described above with reference to FIG. 2, the vertical length of the book stage 200 may be optimized to L1. Since the memory connection terminals 731 and 831 are formed as shown in FIGS. 3A to 3C, the memory connection terminals 731 and the memory connection terminals 931 must be positioned at the same position in order to be coupled to each other.

In such an environment, it may not be easy to slidably engage a book that does not have the optimized longitudinal length L1 to the slide engaging slit 7.

FIG. 5A is a view for explaining a sliding joining method between a slide joining bundle 8 and a slide joining slit 7 having different longitudinal lengths according to an embodiment of the present invention. FIG. 5B is a cross- to be.

5A is an embodiment in which the vertical length L2 of the slide engagement bundle 8 is smaller than the vertical length L1 of the slide engagement slit 7. FIG.

In the present invention, four magnets may be used to match the coupling positions of the memory connection terminal 831 formed in the slide coupling bundle 8 and the memory connection terminal 731 formed in the slide coupling slit 7 .

5A, a magnet 851 arranged in one direction of the memory connection terminal 831 and a magnet 852 arranged in the other direction of the memory connection terminal 831 are provided on the bottom surface of the slide coupling bundle 8, Can be combined. At this time, the exposed surface of the magnet 851 may have a different polarity from the exposed surface of the magnet 852. For example, if the exposed surface of the magnet 851 is S, then the polarity of the exposed surface of the magnet 852 may be N. [

A magnet 751 disposed in one direction of the memory connection terminal 731 and a magnet 752 disposed in the other direction of the memory connection terminal 731 are coupled to the slit bottom portion 73 of the slide coupling slit 7 . At this time, the exposed surface of the magnet 751 may have a different polarity from the exposed surface of the magnet 752. For example, if the exposed surface of the magnet 751 is N, then the polarity of the exposed surface of the magnet 752 may be S.

At this time the magnet 751 and magnet 752 of the slit bottom 73 are brought into contact with the side cover in a manner such that the bound exchangeable book is in close contact with the side cover within the slide engagement slit 100, And can be combined with the magnets 851 and 852, respectively, formed on the slide coupling bundle 8 coupled to the one portion.

At this time, the polarity (e.g., N) of the exposed surface of the magnet 751 and the polarity (e.g., S) of the exposed surface of the magnet 851 may be different and the polarity of the exposed surface of the magnet 752 (E.g., S) and the polarity of the exposed surface of the magnet 852 (e.g., N) may be different. The reason for this is to prevent the magnet 851 portion from engaging with the magnet 752 when the slide engagement bundle 8 is slidably engaged with the slide engagement slit 7, as shown in the arrows in Fig. 5A.

5B, the polarity of the exposed surface of the magnet 861 of the slide coupling bundle 8 and the polarity of the exposed surface of the magnet 862 are equal to each other, and the magnet 761 of the slide engaging slit 7, And the polarity of the exposed surface of the magnet 762 is equal to the polarity of the exposed surface of the magnet 861 when the slide coupling bundle 8 is slidably engaged with the slide engagement slit 7, There is a problem that the polarity is different from the polarity of the exposed surface of the magnet 762 and thus the memory connection terminal 831 can not be slid to the position of the memory connection terminal 731 due to strong coupling with each other.

The distance between the magnet 851 and the memory connection terminal 831 is equal to the distance between the magnet 751 and the memory connection terminal 731 and the distance between the magnet 852 and the memory connection terminal 831 is equal to the distance between the magnet 752 and the memory connection terminal 831. [ It is easy to see that the distance between the memory connection terminals 731 should be the same.

6 is a diagram for explaining a configuration of a smart book stage according to an embodiment of the present invention.

The smart book stage may include a book stage 200 and a media interface unit 300.

The book stage 200 may include a cover 1, a rear cover 2, and a side cover 3.

On the side cover 3 of the book stage 200, a replaceable book may be detachably attached. For example, it is possible to use a configuration in which detachable attachment such as a Velcro tape is possible. That is, in the side cover 3, any one of the hook structure of the pair of velcro tapes and the hook structure of the hook structure is adhered to each other, and the coupling part 110 of the teaching material part 100 is provided with a pair of the velcro tapes It is possible to attach and detach the teaching material part 100 to the book stage 200 by attaching the other one of them.

The media interface unit 300 may include a speaker, a processing unit, a communication unit, a user input unit, and a microphone. The user input unit may include buttons for outputting sound stored in the memory, a button for recording, and a button for instructing reproduction of the recorded sound. The sound collected through the microphone may be stored in a memory inserted in the media interface unit or in a memory inserted in a memory connection terminal formed in a slide coupling bundle of the exchangeable book. The collected sound may be, for example, a voice generated in the process of directly reading the contents recorded in the exchangeable book by a parent or the like.

At this time, the media interface unit 300 may be coupled on the rear cover 2 of the bookstage 200 to provide different sounds according to the types of books inserted into the bookstage 200. A memory slot 310 may be formed in the media interface unit 300 so that the memory card 311 can be inserted therein.

At this time, a plurality of conductors crossing the side cover 3 and the rear cover 2 may be disposed in the book stage 200 so that the side cover 3 and the media interface unit 300 are electrically connected to each other. have.
