Principle of work of the present utility model is as follows:

At first see the course of work of Fig. 3 to embodiment 1 shown in Figure 7, when it adopts penetration to read mode, then will adjust the adjustment of first in eyeglass eyeglass 51 and be repositioned to primary importance by evolution mechanism 70, to penetrate original text 8 again is placed on transparent panel 34 top of carrier plate 32 and carrier plate 32 is inserted in the slots 31, referring to Fig. 3, utilize then light source 40 first luminotron 41 light penetration vertically downward this penetrate original text 8 and shine first of primary importance and adjust in the eyeglass 51, after some reflecting optics 52 and camera lens and being passed in the optical sensor mechanism 54 read to finish penetration.

(guiding mechanism 60 among the figure is circular guide rod when band lower edge guiding mechanism 60 drives at driving mechanism in optically read mechanism 50, also can be slideway structure, and driving mechanism illustrates at the end in the drawings, belong to prior art, so the end is described) when straight line moved, the light source 40 that is fixed on reading mechanism framework 502 tops was that penetration reads the position also make first luminous lamp tube 41 and the first adjustment eyeglass 51 remain on primary importance all the time with moved further also.Reading mechanism 50 and light source 40 synchronous moving process are exactly to penetrating the process that contribution 8 scans, so the full content that penetrates on the original text 8 can constantly be passed in the optical sensor mechanism 54.

When it adopts reflectively when reading mode, then need earlier penetration contribution 8 and carrier plate 32 all to be taken out from slot 31, referring to Fig. 7.Move by the conversion of evolution mechanism again and will adjust eyeglass and transform to the second place, the position that mode is read in i.e. reflection, the evolution mechanism that Fig. 3 to Fig. 7 provides is an a kind of linear reciprocation evolution mechanism 70, therefore, by stepper motor 74 leading screw 73 rotations and traction slide block 71 are moved along slideway 72 straight lines, when moving to the second place by primary importance, the first adjustment eyeglass 51 that slide block 71 tops are fixed also moves to the second place thereupon synchronously, so the time, start second luminotron 42 of light source 40, reflex to again on the first adjustment eyeglass 51 of its below, after making the reflection contribution 3 in its top of its light directive reflective bearing mechanism 20 to reach the purpose that the reflection mode reads.As restart stepper motor, can make evolution mechanism drive the adjustment eyeglass and turn back to primary importance by the second place again.

No matter one of maximum characteristics of embodiment 1 are reflective read or penetration reads exactly, it is same adjustment eyeglasses that first in its evolution mechanism 70 adjusts eyeglass 51.Like this, can reduce the eyeglass usage quantity.

And the difference of structure shown in Figure 8 and structure shown in Figure 7, be exactly only to have adopted a fluorescent tube 42 in the light source 40, promptly towards the fluorescent tube of top, like this, just make it both can constitute the reflective mode that reads with the second place of adjustment eyeglass in the evolution mechanism 70, the light direct projection that can make fluorescent tube 42 again by the perforation vestibule 43 in the light source 40 forms the light that penetrates of downward direct projection to the reflecting element 44, and constitutes penetration and read mode with the primary importance of adjustment eyeglass in the evolution mechanism 70.

Fig. 9 to Figure 11 is the structural drawing of second embodiment of the present utility model, second embodiment and the aforesaid first embodiment difference are that to drive the structure of the evolution mechanism that adjusts the eyeglass shift position different, in addition, it adjusts the usage quantity of eyeglass, structure all has difference, it used one fixing second adjust that eyeglass 55 and one can the translation-angle position first adjust eyeglass 56, so, second adjusts eyeglass 55 can reflect light source to the reflecting optics corresponding with its straight line 52 with the vertical light that penetrates original text 8 that penetrated, camera lens 53 and optical sensor mechanism 54 read to finish penetration.Referring to Fig. 9, face is fixed on the adjustment eyeglass 56 of first in the nutation type evolution mechanism 75 and is in non-blocking position at this moment, promptly is positioned at the primary importance that penetration reads.

When needs are taked reflective when reading mode, then driving top deflection mechanism 75 by external force goes to and relies on spacer pin 79b one side and reach first and adjust eyeglass 56 and be on the second place of blocking position by relying on spacer pin 79a one lateral deviation, therefore, the first light reflection paths of adjusting the eyeglass 56 and the second adjustment eyeglass 55 coincides, so, first adjusts eyeglass 56 is in second when shifting one's position, just in time can block the light of the reflection of the second adjustment eyeglass 55, and the reflected light of second fluorescent tube 42 of light source 40 reflexes to the second place of the first adjustment eyeglass 56 this moment just, thereby constitutes the reflective mode that reads.Referring to Figure 11.

The first adjustment eyeglass 56 is positioned at primary importance or is positioned at the second place and depends on that fully beat mechanism 75 is inclined left side spacer pins or relies on the right side spacer pin partially, and the deflection power of beat mechanism 75 is by carrier plate 32 insertion slots 31 or dials touching mutually of slot 761 with the card on deflecting plate 76 tops and push up realization when slot 31 is extracted out.Referring to Figure 12 to Figure 14, when carrier plate 32 inserts, the edge of its frame 33 then ejection Qian shape slot 761 the right card along and it is push-jump clockwise, promptly be pushed into position shown in Figure 12 as Figure 13, and behind the equilibrium position when deflecting plate 76 turns over bearing pin 77 and fastens 781 line spread of two pegs of hanging spring 78, deflecting plate 76 promptly can be oblique from any lateral deviation of trend.And the pulling force of spring 78 also deflecting plate 76 can be drawn go to blocked by the first or second spacer pin 79a or 79b till.So when carrier plate 32 inserted, it can and fall the extremely primary importance of non-blocking-up after rise to the commentaries on classics of spacer pin 79a one lateral deviation, promptly implements the position that penetration reads.Referring to Fig. 9 and Figure 12.And penetrate original text 8 and also insert just in the penetration bearing mechanism 30 this moment.

And when carrier plate 32 is drawn out of, in the time of just will carrying out reflective reading operation, 76 of deflecting plate are driven band to counter clockwise direction deflection by frame 32, adjust that eyeglass 56 changes angle positions and the second place that enters blocking-up and make it drive first, promptly implement reflective position of reading, referring to Figure 11 and Figure 14, this moment, penetration bearing mechanism and contribution 8 took out just fully, so do not influence reflective reading operation.

Here need to prove: deflection mechanism 75 is in the primary importance or the power of the second place, also can realize by Figure 15 and Electromagnetic Control mechanism 80 shown in Figure 16, promptly the front end at moving member 81 adds a fixture block 82, fixture block 82 can be moved and promote or spur deflecting plate 76 to realize from primary importance to the second place or from the conversion of second place primary importance in Qian shape slot 761.

Here also emphasize a bit, be exactly Figure 12 to structure shown in Figure 14 be first to adjust the transmission that eyeglass 56 can blocking-up second be adjusted the light that eyeglass 55 reflected, therefore, must adjust eyeglass 56 with first is arranged on the position mapping device 75, but if adjust the transmission light that eyeglass 55 will be blocked the first adjustment eyeglass 56 second, then the adjustment of first among second embodiment eyeglass 56 must maintain static, first adjusts eyeglass 55 then should be arranged on the position mapping device 75, but the conversion of enforcing location and finish reflection or penetration reading operation too.

The 3rd embodiment difference from Example 2 shown in Figure 17 is exactly that it is divided into three parts with optically read mechanism 50, be about to camera lens 53, induction mechanism 54 directly moves to and is fixed in the body 10, and will adjust eyeglass and evolution mechanism 75 still is retained in the framework 502 and moved back and forth by drive mechanism, reflecting optics group 52 in the former reading mechanism 50 then is separated into a separate component mobile unit, and this structure equally also can be finished aforesaid every work.
