Description

Teaching blank scanner

The utility model relates to a kind of teaching blank scanner, this scanner mainly can scan literal or the figure of writing on blank, and data can be got off by computer and printer prints, so that the student can attentively pay attention to the class and needn't take notes, can wait the student to take notes when the lecturer gives lessons, and can improve the quality of teaching.

Image analyzer now, it generally is the principle of utilizing duplicating machine, with glass plate as the storing district of putting image file, again by being positioned at the excellent type light source of glass plate below, move towards the right side in left side by glass plate, and light can be projected in regular turn each position of the image file above the glass plate, and the picture receiver (CCD or CIS image inductor) that the image by the reflecting mechanism reflection returns to the glass plate below locates, and then reach the scan action of image document.

Present employed blank is the flat board of a rectangle, and when the lecturer goes up class hour by blank writing words or figure to the student, the student must simultaneously pay attention to the class one side and take notes, and still, there is following shortcoming in said structure:

1 can't write down the written contents on the blank;

No matter 2 be that traditional scanner or blank etc. all can be because of being subject to the large and small of cabinet size own, and its sweep length and scope also can be restricted;

3 traditional blanks, volume is comparatively huge, uses inconvenience.

Fundamental purpose of the present utility model is to provide a kind of function teaching blank scanner how, and it can scan literal, the graphic documentation of being write on the blank by image read-out, and can print by equipment such as computer and printers.

Another purpose of the present utility model is to provide a kind of teaching of adjusting sweep limit blank scanner.

For the utility model that achieves the above object is taked following measure:

Teaching of the present utility model blank scanner includes a blank with suitable length and area; It is characterized in that: the blank rear is provided with a parallel retainer, parallel retainer the place ahead is provided with an image reading apparatus, this device comprises: the loam cake that is taken the shape of the letter U by side-looking, loam cake is positioned at blank the place ahead, between between loam cake and blank, be sequentially provided with linear optical sensing device, lamp socket and tube face from front to back, be used for blank is thrown light on fluorescent tube; Have a parallel gear train, be combined with motor, driving wheel, engaged wheel, pulley, rope yarn etc., parallel gear train can drive parallel retainer, loam cake, fluorescent tube, tube face and linear optical sensing device, for literal or the figure of scanning induction on blank.

Wherein: described blank and left and right fixed head can be large and small and do conversion according to the length of blank and scope.

Wherein: described parallel gear train comprises: parallel retainer, parallel retainer rear is provided with a motor, the transmission shaft of motor passes parallel retainer and drives on the driving wheel, driving wheel can be respectively and two engaged wheel A, the mutual transmission of B: the upper and lower position that is positioned at parallel retainer is provided with pulley with four corners respectively, the upper and lower position of left side fixed head also is provided with pulley, and the upper and lower position of right fixed head is respectively equipped with a upper and lower holder; One rope yarn is twined on one group of pulley on right side, parallel retainer top by the upper fixed seat place, rope yarn is wound in engaged wheel A again, rope yarn laterally is pulled on one group of pulley of left fixed head via the oblique one group of pulley in parallel retainer bottom again, laterally wear again to the one group of slip that is positioned at left side, parallel retainer top, be wound to engaged wheel B again after by being positioned on one group of oblique pulley of parallel retainer below, at last, rope yarn is fixed in the lower fixed seat place of right fixed head bottom.

Compared with prior art, the utlity model has following effect:

1 the utility model be can be with the literal on the conventional white board, graphic documentation by image read-out to scan.

2 is easy to use, for scanning such as portrait, calligraphy work, engineering drawing and other the plane works of paper, as long as will be scanned on the surface that article are fixed in blank, just can scan.

3 can adjust sweep limit, and the utility model can increase sweep limit as long as the left and right fixed head of both sides and blank extended laterally.

4 users need not to purchase bulky scanning device, as conventional white board, as long as the utility model is set up on the existing blank front, can has and can scan the literal write on blank or the scanning effect of figure.

Further specify specific structural features of the present utility model below in conjunction with accompanying drawing.

Brief Description Of Drawings:

Fig. 1 is a three-dimensional combination figure of the present utility model.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a floor map of the present utility model.

As shown in Figure 1, 2, teaching of the present utility model comprises with the blank scanner: one has proper area and rectangular blank 10, can supply writing words or figure on the blank 10, use when giving lessons for the lecturer, the both sides of blank 10 are respectively arranged with left and right fixed

head

12,14, and blank 10 and left and right fixed

head

12,14 can be according to the length of blank 10 or range size and done locational conversion.

Blank 10 rears are provided with a parallel retainer 20 that is taken the shape of the letter U by side-looking, parallel retainer 20 the place aheads are provided with an image read-out, device includes: the loam cake 22 that is taken the shape of the letter U by side-looking, loam cake 22 is positioned at the place ahead of blank 10, between loam cake 22 and blank 10, be sequentially provided with linear optical sensing device 28 from front to back, lamp socket 26 and tube face 24 etc., fluorescent tube 26 can be for the literal or the figure that throw light on and write on blank 10, and can write literal or figure on blank 10 in order to induction with linear optical sensing device 28, portrait, calligraphy work, engineering drawing and other plane works just can scan as long as scan articles is fixed on the surface of blank 10.
