The two ends of first roller 228, second roller 230 and the 3rd roller 232 extend outward first axostylus axostyle 242, second axostylus axostyle 244 and the 3rd axostylus axostyle 246 respectively, as shown in Figure 3.Making first roller 228, second roller 230 and the 3rd roller 232 is that rotate in the axle center with first axostylus axostyle 242, second axostylus axostyle 244 and the 3rd axostylus axostyle 246 respectively.Even first roller 228, second roller 230 and the 3rd roller 232 are penetrated fixing by first axostylus axostyle 242, second axostylus axostyle 244 and the 3rd axostylus axostyle 246 respectively.First roller 228 is positioned at the top, edge of scanning platform 210, the 3rd roller 232 is disposed in the cover plate 208 of Fig. 2 in the mode relative up and down with second roller 230, and the bearing of trend of second axostylus axostyle 244 and the 3rd axostylus axostyle 246 is parallel with the scanning moving direction of the ray machine 214 of Fig. 2.
It should be noted that, one end of first axostylus axostyle 242, second axostylus axostyle 244 and the 3rd axostylus axostyle 246 of Fig. 3 is an end of axle center, second driven gear, 226 axle center and the motion bar 236 of first driven gear 224 of connection layout 2 respectively, and the other end of motion bar 236 is connected in relatively turnable mode with the axle center of first driven gear 224.In addition, being familiar with the other end that this technical staff understands first axostylus axostyle 242, second axostylus axostyle 244 and the 3rd axostylus axostyle 246 of Fig. 3 is fixed on the supporting construction (not being shown among Fig. 3) in rotating mode respectively.
That is to say, first roller 228 is connected with first driven gear 224 by first axostylus axostyle 242, in order to rotating with first direction or second direction synchronously, and drive contribution 212 and enter or leave side inversion set 220 with driving gear 222 and first driven gear 224.Second roller 230 is connected with second driven gear 226 by second axostylus axostyle 244, in order to rotate synchronously with the driving gear 222 and second driven gear 226.The mode that the 3rd roller 232 is relative up and down with second roller 230 is disposed in the cover plate 208, in order to clamping contribution 212 up and down with second roller 230, and rotates with first direction synchronously and drives contribution 212 and advance.
The track 238 that circles round is disposed in the casing 202, and is positioned at the below of cover plate 208 and the 3rd roller 232, passes through and counter-rotating contribution 212 in order to the part 212 of submitting the article.Baffle plate 234 is disposed on the side plate 209 and is higher than the lower edge of second roller 230, and baffle plate 234 also is positioned at the inlet outside of the track 238 that circles round, and enters the track 238 that circles round in order to guiding contribution 212.Infrared end 240a and infrared ray receiving terminal 240b are disposed near the both sides of outlet of the track 238 that circles round, and in the cover plate 208 of the outlet of the track 238 that circles round between first roller 228 and second roller 230, the inlet of the track 238 that promptly circles round and outlet are two openings in the cover plate 208.
Please refer to Fig. 4, what it illustrated is the calcspar of the scanner of Fig. 2.In Fig. 4, side inversion set 220 has a control unit 252, couples with driving gear 222, motion bar 236, ray machine 214, infrared end 240a and infrared ray receiving terminal 240b.Control unit 252 control infrared end 240a send infrared ray always and give infrared ray receiving terminal 240b, if when having thing to block infrared end 240a in the track 238 that circles round to send infrared ray, infrared ray receiving terminal 240b will not receive infrared end infrared ray that 240a sends.At this moment, infrared ray receiving terminal 240b will export an interrupt signal and give control unit 252, and control unit 252 receives this interrupt signal and controls driving gear 222 according to this and changes rotation direction.That is to say, control unit 252 receives been scanned signal or interrupt signal and controls driving gear 222 according to this and rotate with first direction or second direction, and first driven gear 224 in control unit 252 when receiving been scanned signal or interrupt signal with driving gear 222 engagements or disengaging.
As for the side inversion set 220 of the present invention contribution that how to reverse, its flow process is described as follows in regular turn.Refer again to Fig. 2, before the user inserted contribution 212 backs at the beginning and scans, the user can utilize the operation interface (not being shown among Fig. 2) of scanner 200 to select the single or double scan pattern.After the user selects the duplex scanning pattern and ray machine 214 scanning when completing the manuscript the positive 212a of part, ray machine 214 will export the one scan signal that finishes will for control unit 252.Then, after control unit 252 receives this been scanned signal, control unit 252 control motion bars 236 make first driven gear 224 and driving gear 222 engagements, and first roller 228 will be clamped contribution 212 up and down with the edge of scanning platform 210 near driving gear 222.Wherein, ray machine 214 begins to return scanning starting position.
Then, control unit 252 control driving gears 222 rotate with a first direction, and driving gear 222 will drive first driven gear 224, second driven gear 226, first roller 228 and second roller 230 and rotate synchronously with first direction, as shown in Figure 5.Second roller 230 will drive the 3rd roller 232 and rotate, and first roller 228 will drive contribution 212 past second rollers 230 and advance.
When treating that second roller 230 and the 3rd roller 232 are clamped contribution 212 up and down, as shown in Figure 6, contribution 212 will advance toward baffle plate 234 along with the rotation of second roller 230 and the 3rd roller 232.Then, the present invention can design control unit 252 and control motion bar 236 away from driving gear 222 after driving gear 222 begins to rotate a period of time, make first driven gear 224 break away from driving gear 222, and first roller 228 is away from the edge of scanning platform 212.It should be noted that after driving gear 222 begins to rotate a period of time second roller 230 and the 3rd roller 232 are wanted to clamp contribution 212 up and down, and rotate synchronously to drive contribution 212 and advance.So just can carry out the action that first driven gear 224 breaks away from driving gears 222, but be principle with the rotation that does not influence driving gear 222.
Then, contribution 212 is subjected to the guiding of baffle plate 234 and enters in the track 238 that circles round via the inlet of the track 238 that circles round, as shown in Figure 7.When contribution 212 circles round track 238 when blocking the infrared ray that infrared end 240a sent at downside, infrared ray receiving terminal 240b can't receive the infrared ray that infrared end 240a is sent.At this moment, infrared ray receiving terminal 240b exports an interrupt signal to control unit 252.Receive interrupt signal after a period of time at control unit 252, the end that second roller 230 and the 3rd roller 232 just drive contribution 212 exposes via the outlet of the track 238 that circles round, and the leading edge of contribution 212 is also just between the edge of first roller 228 and scanning platform 210.Control unit 252 will be controlled motion bar 236 near driving gear 222, make first driven gear 224 and driving gear 222 engagements, and first roller 228 be clamped contribution 212 up and down with the edge of scanning platform 210.
Then, control unit 252 control driving gears 222 rotate with a second direction opposite with first direction, and driving gear 222 will drive first driven gear 224, second driven gear 226, first roller 228 and second roller 230 and rotate with second direction synchronously.Second roller 228 will drive the 3rd roller 230 and rotate, and first roller 228 will drive contribution 212 past scanning platforms 212 and advance.
Treat that contribution 212 leaves circle round track 238 and infrared ray receiving terminal 240b and receives infrared ray that infrared end 240a sent once more after a period of time, contribution 210 has been got back on the scanning platform 210.And contribution reverse side 212b down, and ray machine 214 has been got back to scanning starting position.Then, control unit 252 control driving gears 222 stop operating, and control motion bar 238 make first driven gear 224 break away from driving gear 222, and first roller 228 is away from scanning platform 212, as shown in Figure 8 away from driving gear 222.Even the present invention can design control unit 252 and control driving gear 222 after longer a period of time and stop operating in receiving interrupt signal, and contribution 212 is just got back on the scanning platform 210.Then, ray machine 214 will begin motion scan contribution reverse side 212b along the direction parallel with second axostylus axostyle 244 and the 3rd axostylus axostyle 246,, not given unnecessary details in this omission as for the follow up scan action.
So known to above-mentioned, the present invention can provide a contribution duplex scanning method, as shown in Figure 9.In Fig. 9, at first, in step 902, ray machine is begun to scan the front of contribution by scanning starting position.Then, enter in the step 904, the output scanning signal that finishes when ray machine is completed the manuscript part positive in scanning, and ray machine begins to return scanning starting position.Then, enter in the step 906, the control unit of side inversion set receives the been scanned signal, makes the side inversion set sandwich contribution by a side of scanning platform.Then, enter in the step 908 side inversion set counter-rotating contribution.Then, enter in the step 910, the side inversion set is sent contribution on the scanning platform back to, and ray machine has been got back to scanning starting position.Then, enter in the step 912, ray machine is begun to scan the reverse side of contribution by scanning starting position.Make ray machine can scan the reverse side of contribution, this method comes to an end eventually.
Yet be familiar with this operator and can understand that also technology of the present invention is not limited thereto.For example, infrared end and infrared ray receiving terminal also can use other sensing cells to substitute, and still can reach the effect of sensing.In addition, the motion bar that connects first driven gear and the 3rd axostylus axostyle substitutes can use other movable devices or belt group, still can reach the effect that moves first driven gear.In addition, also can install several rollers additional on first axostylus axostyle, second axostylus axostyle and the 3rd axostylus axostyle, to strengthen the effect of holding paper and the transmission of drive contribution.Side inversion set of the present invention also can install an exterior case additional outward, in order to the protection inner body.Even, can install an automatic paper feeder additional on the cover plate outside the opposite side of scanning platform, use for the user and on scanning platform, import contribution, and reach the effect of mutual coupling with side inversion set of the present invention.
The radius that it should be noted that driving gear must be greater than the radius of first driven gear and second driven gear.The present invention also can omit the element of driving gear, makes control unit can directly control the rotation of first driven gear and second driven gear, need not see through the rotation media of driving gear.Even the present invention also can change the track that circles round for walking around another track that circles round of second roller top, also can reach the contribution effect of reversing.
When if the present invention omits infrared end and infrared ray receiving terminal or other sensing cells, the present invention must design several time points and control the engagement of turning to of driving gear and first driven gear and driving gear or break away from action, to reach the effect of contribution counter-rotating.
With whole time flow, at first, control unit control motion bar after driving gear rotates first period with first direction first driven gear and driving gear are broken away from, and first roller is away from scanning platform away from driving gear.At this moment, second roller and the 3rd roller are wanted to clamp contribution up and down, and rotate synchronously to drive contribution and advance.
Then, control unit control motion bar after driving gear rotates greater than second period of first period with first direction make the engagement of first driven gear and driving gear, and contribution is clamped at the edge of first roller and scanning platform up and down near driving gear.At this moment, the leading edge of contribution has been left the track that circles round, and control unit will be controlled driving gear and rotate with second direction.
Then, control unit is controlled driving gear and is stopped operating driving gear rotates the 3rd period with second direction after, contribution is just got back on the scanning platform.
The disclosed scanner with side inversion set of the above embodiment of the present invention, its side inversion set is positioned at the design of a side of scanning platform, can be in the complete the manuscript positive back counter-rotating contribution of part of scanner scans, to reach the effect of contribution duplex scanning.Thus, the user need be in manual mode with the contribution turn-over, and is quite convenient.
