In data processing section 112A, a picture intelligence processing section 114 will compare with a threshold value from this pictorial data D1 (analogue data) of these image reading part 107 inputs, and this pictorial data D1 is carried out quantification or other processing.This reads control section 113A according to a document detection signal S1 as a flop signal, output is used for a drive signal S2 of this image reading part 107 of drive controlling, and control is provided, has experienced the processing of this picture intelligence processing section 114 so that read pictorial data D1.
Below, the operation of this image reader 100 of 1 will be described according to the embodiment of the present invention with reference to figure 4 shown flow graphs.When this image reader 100 (document detection part 105) of Fig. 1 does not have near under the situation of this document P, when a power switch that is not shown is opened, this of Fig. 3 read the processing (with reference to figure 4) of control section 113A execution in step SA1, wherein regulation (setting) number of the row read as pictorial data, and this processing forwards step SA2 to then.
Here, phrase " number of row " is illustrated in the number of the row on the direction (being described to the scanning direction) that this document P goes up, this image reader 100 moves.The number of row multiply by the area that the width of this image reading window 101b on this longitudinal direction just provides the image that this image reader 100 can read.
In step SA2, this visual control section 113A judges whether this document detection part 105 detects a document P, in other words, judges whether this document detection signal S1 is exported from this document detection part 105.In this stage, when this shown among Fig. 1 document detection part 105 does not have near this document P, and this document detection signal S1 is not by from 105 outputs of this document detection part the time, the judged result that this reading control section 113A identifies step SA2 is a "No", and repeats this identical judgement.
Then, this user is placed on this image reader 100 on this document P in such mode, so that this image reading surface 101a catches this document of contact P under the situation of this image reader 100 as shown in Figure 1 this user.When this document detection part 105 and document P more mutual near the time, a document detection signal S1 is outputed to this and is read control section 113A from this document detection part 105.
By this operation, the judged result that this reading control section 113A identifies among the step SA2 is a "Yes", and system's control forwards step SA3 to.In step SA3, this is read control section 113A and exports a drive signal S2 with a predetermined distance to this image reading part 107 continuously.Like this, this drive signal S2 is by from 107 inputs of this image reading part the time each time, the pictorial data D1 of the delegation on this document P is output to a picture intelligence processing section 114, and this picture intelligence processing section 114 quantize this pictorial data D1 and then this pictorial data D1 be imported into this and read control section 113A.
By this operation, in step SA3, this is read control section 113A and reads a row image data D1 of this input.Here, this user slides this image reader 100 on this scanning direction.Roller 104,104 ... because Fig. 1 in shown this document P and roller 104,104 ... between a frictional force and rotate.So, because roller 104,104 ... rotation, this user is this image reader 100 of slip on this scanning direction smoothly.Because this slide, when this drive signal S2 was transfused to each time, a row image data D1, was input to this through this picture intelligence processing section 114 and reads control section 113A from this image reading part 107 by continuously.Like this, just carried out a scan operation.
Then, in step SA3, when this reading control section 113A read this row image data D1, system's control forwarded step SA4 to, and this document detection part 105 judges whether to detect this document P among the step SA4.Here, when this image reader 104 slides on this document P, in other words, when carrying out this scan operation, when this document detection part 105 was positioned at position of close this document P, this document detection signal S1 was outputed to this and is read control section 113A from this document detection part 105.
Under this situation, a scan operation just is performed, and this document detection signal S1 is just being outputed to this and is being read control section 113A from this document detection part 105, so it is "Yes" that this reading control section 113A identifies the judged result of step SA4, and system's control forwards step SA5 to.In step SA5, this is read control section 113A and judges whether read a pictorial data D1 that defined amount is capable in step SA1.Under this situation, be less than a specified number or amount if read the corresponding head office of pictorial data D1 number with this, the judged result that this reading control section 113A identifies among the step SA5 is a "No", and this system's control turns back to step SA3.This is read control section 113A and repeats the sequence of operation described above.In step SA3, just carry out the sequence of operation that this reads the pictorial data D1 of one second row and delegation then.In step SA5, when reaching a specified number or amount with this number by the corresponding row of read data D1, it is "Yes" that this reading control section 13A identifies judged result, and finishes to read this operation of this image then.
During above-mentioned this scan operation, when this user separates this image reader 100 (document detection part 105) and takes away this image reader 100 and finish to read this operation of an image with this document P, just stopped from this document detection signal S1 of these document detection part 105 outputs.By this, the judged result that this reading control section identifies step SA4 is a "No", and finishes to read this operation of this image.
As above-mentioned, by above-mentioned this image reader 100 according to embodiment of the present invention 1, this reading control section 113A judges the beginning or the end of reading according to a testing result of this document detection part 105 (document detection signal S1) or is not reading.Like this, do not need a user to operate the instruction that a switch provides beginning or finishes to read an operation of this image like that, so improved the convenience of using to conventional art.
Described this image reader 100 in detail according to embodiment of the present invention 1, but the structure of this image reader 100 is not limited to said structure, in main idea of the present invention the design of this image reader is made amendment and change includes within the scope of the invention.For example, in this image reader 100 according to above-mentioned execution mode 1, as shown in Figure 1, this document detection part 105 is connected to a position near this image reading window 101b, but this structure is not restricted to this structure, and this image reading window 101b may be provided in any one position of this image reading surface 101a.Simply, if this image reading window and this document detection part 105 (image reading surface 101a) on identical plane, any position all allows.
This image reader 100 according to above-mentioned execution mode 1 is connected to a computer (not showing) through this shown cable 106 of Fig. 1, so this image reader 100 is used as an external device of this computer on function.But this image reader 100 may be a type that can work alone.
With reference to the image reader 200 of figure 4 to Fig. 6 descriptions according to embodiment of the present invention 2.Fig. 5 is that demonstration is according to the outward appearance of this image reader 200 of execution mode 2 and a lateral plan of structure.In this drawing, identical label be assigned to Fig. 1 in the similar parts of those parts, and the descriptions thereof are omitted.In Fig. 5, use a mechanical switch 201 to come this shown in the alternate figures 1 document detection part 105.
This mechanical switch 201 is connected to this image reading window 101a, and a button 201a that can move around in (in the drawings on the represented direction of arrow X) on the direction perpendicular to this image reading surface 101a is arranged.Be similar to this mechanical switch of this document detection part 105 (with reference to figure 1) 201 and detect a document P, and executable operations mechanically.Promptly, when 201a contact this document P and because from a drift (moving) that thrust produced this document P, on the direction represented by this arrow X when a threshold value, this mechanical switch 201 is exported document detection signal S1 (with reference to figure 6).
Fig. 6 is a block diagram that shows according to the electrical structure of this image reader 200 of execution mode 2, and in this drawing, identical label be assigned to Fig. 3 and Fig. 5 in the similar parts of those parts.In Fig. 6, a scanner part 202 is provided to this shown in the alternate figures 3 scanner part 111.
In this scanner part 202, this mechanical switch 201 (with reference to figure 5) is provided to this shown in the alternate figures 3 document detection part 105.When of this moveable part 201a (with reference to figure 5) was moved beyond this threshold value, document detection signal S1 of these mechanical switch 201 outputs read control section 113A to this.
Be described with reference to Figure 4 operation according to this image reader 200 of above-mentioned execution mode 2.In Fig. 5, do not have near under the state of this document P at this image reader 200 (this mechanical switch 201), when a power switch that is not shown is opened, shown this read the processing among control section 113A execution in step SA1 (with reference to figure 4) among Fig. 6, stipulated the number of the row of the pictorial data that (setting) will read among the step SA1, this system's control forwards step SA2 to then.
In step SA2, by detecting whether receive this document detection signal S1 from this mechanical switch 201, this is read control section 113A and judges whether this mechanical switch 201 detects a document P.In this stage, this button 201a of this shown mechanical switch 201 does not contact this document P among Fig. 5, so and not from this mechanical switch 201 this document detection signal of output S1.Like this, this judged result of reading among the control section 113A identification step SA2 is a "No", and repeats this identical judgement.
Here suppose that a user catches this image reader 200 that is used to read an image as shown in Figure 5, and this image reader 200 is placed on this document P, so that this image reading surface 101a contacts this document P.By this, when this button 201a of this mechanical switch 201 contacts this document P and when this document P receives a thrust, this button 201a along as shown in the figure up direction (direction X) move.When of this button 201a was moved beyond a threshold value, this document detection signal S1 was outputed to this by this shown from Fig. 6 mechanical switch 201 and reads control section 113A.
By this, this judged result of reading that control section 113A identifies among the step SA2 is a "Yes", and system's control forwards step SA3 to, and continuously with a predetermined distance to drive signal S2 of these image reading part 107 outputs.In this step, as above-mentioned, when this drive signal S2 was transfused to each time, the pictorial data D1 of the delegation on this document P was output to this picture intelligence processing section 114.By this operation, this is read control section 113A and reads this pictorial data D1 that is quantized by this picture intelligence processing section 114.
When this user slided this image reader 200 on this scanning direction, a row image data D1 was input to this through this picture intelligence processing section 114 from this image reading part 107 continuously and is read control section 113A.Like this, just carried out a scanning.In step SA4, this is read control section 113A and judges whether this mechanical switch 201 has detected this document P, and under this situation, judge that this document detection signal S1 is imported from this mechanical switch 201, this result who reads control section 113A identification judgement is a "Yes", and system's control forwards step SA5 to.Like this, this is read control section 113A and repeats above-mentioned this process.
During above-mentioned scan operation, when dividing this image reader 200 and this document P, this user comes when finishing this and reading the operation of this image, because from a thrust vanishing on this button 201a this document P, that act on this mechanical switch 201, so this button 201a turns back to its initial position.As a result, this mechanical switch 201 stops to export this document detection signal S1, so this judged result of reading among the control section 113A identification step SA4 is a "No", and finishes to read this operation of this image.
As above-mentioned, by this image reader 200 according to execution mode 2, provide this mechanical switch 201, and this reads control section 113A judges reading according to a testing result (document detection signal S1) of this mechanical switch 201 beginning and end.Like this, a user does not need to operate the instruction that a switch begins and finish an operation of an image of reading, so use and the mode identical, improved the convenience of actual use according to this image reader 100 of embodiment of the present invention 1.
By above-mentioned this image reader 200 according to execution mode 2, except above-mentioned these effects, also have an effect,, just can not produce because the misoperation that electrical noise causes promptly because used this mechanical switch 201 to detect a document P with a mechanical system.Because this feature, use is according to this image reader 200 of execution mode 2, the precision of using this mechanical switch 201 to detect a document P is very high, thus paper do not wish to occur move and can not occur and can improve the precision of reading an image.
Further by above-mentioned this image reader 200 according to execution mode 2, this mechanical switch 201 that carries out mechanical action is used, thus do not need to be used to control a control circuit of its operation, so reduced this expense.
Above this image reader 200 according to embodiment of the present invention 2 is described in detail, but the electrical structure according to this image reader of the present invention is not limited to execution mode 2, in main idea of the present invention its design is made amendment and change comprises within the scope of the invention.In the superincumbent execution mode 2, this mechanical switch 201 with this button 201a is described as be in according to a unit in this image reader 200 of execution mode 2, that be used to detect a document P, but structure is not limited to this structure, suppose that it can detect a document P by mechanically actuated operation, just can use the detecting unit of any kind.
Be similar to this image reader 100 according to execution mode 1, by this image reader 200 according to above-mentioned execution mode 2, this shown among Fig. 5 mechanical switch 201 may be provided in any position, as long as this position is in the scope of this image reading surface 101a.
To Fig. 9 a image reader 300 according to embodiment of the present invention 3 is described below with reference to Fig. 4 and Fig. 7.Fig. 7 is that demonstration is according to the outward appearance of this image reader 300 of execution mode 3 and a cut-away section lateral plan of structure.In this drawing, identical label is assigned to the similar parts of parts among those and Fig. 1, and the descriptions thereof are omitted.In Fig. 7, provide an optoelectronic switch 301 to come this shown in the alternate figures 1 document detection part 105.
This optoelectronic switch 301 is one and is connected to the optical interruption device of this image reading surface 101a and can detects this document P optically.This optoelectronic switch 301 comprises and is used at the light emitting members 301a of direction (direction towards this document P that figure is a shown) emission light Ya forward and is used for receiving the light-receiving member 301b of light (the reverberation Yb of figure).
Below, will be described with reference to Figure 8 the structure of this optoelectronic switch 301.In this shown in this drawing optoelectronic switch 301, this light emitting members 301a and light-receiving member 301b are close mutually, and are integrated among the encapsulation 301c.For example, the size of this optoelectronic switch 301 is millimeter (in a longitudinal direction) * 2,3 millimeters (horizontal direction) * 4 millimeter (thickness).
For example, this light emitting members is an infrared light emitting diode, and as above-mentioned emission light Ya.On the other hand, this light-receiving member 301b is, for example, and a light register, and receive the corresponding light signal S4 of amplitude (with reference to figure 9) of input light and output and this reception light.
Here, this light-receiving member 301b is parts as shown in Figure 7, that be used for receiving this reverberation Yb from this document P (reflecting surface), and when the surface of this light emitting members 301a (perhaps light-receiving member 301b) and the distance between this document P (reflecting surface) were 1 millimeter, the level of this receiving optical signals S4 reached a peak value.When the distance between these parts 301a and this document P increased, the level of this signal S4 reduced.
Connector 301d and connector 301e are connected respectively to an anode and negative electrode of this light emitting members 301a, and a further connector 301f and connector 301g are connected to an emitter and collector of this light-receiving member 301b.
Fig. 9 is a block diagram that shows the electrical structure of above-mentioned this image reader 300 according to execution mode 3.In this view, identical label be assigned to Fig. 3 and Fig. 7 in the similar parts of parts.In Fig. 9, provide a scanner part 302 to come this shown in the alternate figures 3 scanner part 111.In this scanner part 302, provide an optoelectronic switch 301 to come this shown in the alternate figures 3 document detection part 105.In addition, in Fig. 9, newly provide a comparator 303.
In Fig. 9, these optoelectronic switch 301 outputs and corresponding this light signal S4 of the light intensity that is received by this light-receiving member 301b (with reference to figure 7).This comparator 303 is read between the control section 113A at this optoelectronic switch 301 and this, and a threshold value that pre-sets is compared with this level that is received light signal S4 of importing from this optoelectronic switch 310.Here, this threshold value and a distance corresponding (be called image reading and enable distance) that enables an image of these image reader 300 readings.
When the level of this light signal S4 is less than this threshold value, this comparator 303 will represent that a document detection signal S1 who has detected this document P outputs to this reading control section 113A, and stop to export this document detection signal S1.
Be described with reference to Figure 4 operation according to this image reader 300 of execution mode 3.In Fig. 7, under this image reader 300 (optoelectronic switch 301) is not positioned at situation near the position of this document P, when a power switch that is not shown is opened, this reading control section 113A shown among Fig. 9 forwards this system's control to step SA1 (with reference to figure 4), among the step SA1, regulation (settings) number of row of the pictorial data that can read of this operation, this system controls and forwards step SA2 to then.
In step SA2, this is read control section 113A and whether judges from this comparator 303 this document detection signal of input S1 whether this optoelectronic switch 301 has detected a document P by detecting.Under this situation, if this optoelectronic switch 301 that Fig. 7 is shown and a distance between this document P more than above-mentioned this image reading enable apart from the time, by enter into the light intensity very little (perhaps according to not entering) of this light-receiving member 301b from the reverberation that obtains by the light Ya of this light emitting members 301a emission in the reflection of this reflecting surface.
So, under this situation, even this shown from Fig. 9 optoelectronic switch 301 receives this light signal S4,,, this comparator 303 exports this document detection signal S1 so not reading control section 113A to this because this threshold value of level ratio of this light signal S4 is little.So this is read control section 113A and judges that this document P is not detected by this optoelectronic switch 301, and the judged result that identifies step SA2 is "No", and repeats this identical decision operation.
This user is placed on this image reader 300 on this document P in such mode then, so that this image reading surface 101a catches this document of contact P under the situation of this shown image reader 300 of Fig. 7 this user, be similar to above-mentioned this operation.By this operation, this optoelectronic switch 301 (more precisely, be this light emitting members 301a and this light-receiving member 301b) and this document P between distance reduce gradually, so become big from the quantity of the light Ya of this document P reflection, as a result, enter the quantity increase of the light of this light-receiving member 301b.
As this image reading surface 101a (optoelectronic switch 301) during near this document P, increase from the level of this light signal S4 of these shown these optoelectronic switch 301 outputs of Fig. 9, so the level of this receiving optical signals S4 surpasses this threshold value in the comparator 303.
By this, this document detection signal S1 is read control section 113A output from this, and this to read the judged result that control section 113A identifies step SA2 be "Yes", this system's control forwards step SA3 to.
In step SA3, this is read control section 113A and exports a drive signal S2 with the interval of a regulation continuously to this image reading part 107, is similar to aforesaid operations.In this step, be similar to aforesaid operations, each next drive signal S2 is by from 107 inputs of this image reading part the time, and the row image data D1 on this document P just is output to this picture intelligence processing section 114.By this, the row image on this document P that is handled by this picture intelligence processing section 114, is read control section 113A by this and is read as pictorial data D1 by continuously.
When a user slides this image reader 300 on this scanning direction, one row image data D1 is input to this through this picture intelligence processing section 114 from this image reading part 107 continuously and is read control section 113A, has so just carried out a scanning.
In step SA4, this is read control section 113A and judges whether this optoelectronic switch 301 detects this document P, under this situation, this is read control section 113A and judges that this document detection signal S1 is imported from this comparator 303, and identifying judged result is "Yes", and system's control forwards step SA5 to.Then, this is read control section 113A and repeats said process.
In this scan period, if a user separates this image reader 300 with this document P, and it is taken away this operation that finishes to read an image, because the distance between this image reading surface 101a (optoelectronic switch 301 of saying so accurately) and this document P increases, reduce relatively so enter into the quantity of the light Yb of this light-receiving member 301b.
When from this threshold value of level ratio of this light signal S4 of shown this optoelectronic switch 301 outputs of Fig. 9 hour, this comparator 303 stops to export this document detection signal S1.By this operation, this is read control section 113A and judges that this document P is not detected by this optoelectronic switch 301, and the judged result that identifies step SA4 is "No", and finishes to read this operation of this image.
As above-mentioned, by using above-mentioned this image reader 300 according to execution mode 3, provide this optoelectronic switch 301 and comparator 303 that level and a threshold value of this light signal S4 are compared, and this read control section 113A judges reading according to comparative result beginning and end.Like this, different with a image reader according to conventional art, user does not need to operate the instruction that a switch begins and finish to read an operation of this image, so use and the convenience of having improved actual use according to the identical mode of this image reader 100 of execution mode 1.
By using above-mentioned this image reader 300 according to execution mode 3, except above-mentioned effect, also use this optoelectronic switch 301 to detect a document P and do not contact this document, so the decreased performance that produces because of the friction of document P can not occur.
So by using above-mentioned this image reader 300 according to execution mode 3, this image reader 300 does not directly contact this document P, so the life-span of parts (optoelectronic switch 301) has postponed.In addition, by using this image reader 300 according to execution mode 3, during a scan operation, this optoelectronic switch 301 can be by the influence of the surface heterogeneity of this document P, so a mistake of reading image can not occur.Like this, can improve the precision of image reading.
Described this image reader 300 according to execution mode 3 in detail, but be not limited to this structure according to the structure of image reader of the present invention, modification and change in main idea of the present invention include within the scope of the invention.For example, in above-mentioned this image reader 300, use this optoelectronic switch 301 (optical interruption device) to detect a document P, but its structure is not limited to this structure according to execution mode 3, suppose that it can detect a document P optically, can use the switch of any kind.
With reference now to Figure 10, to Figure 12 a image reader 400 according to embodiment of the present invention 4 is described.Figure 10 shows according to the embodiment of the present invention the outward appearance of this image reader 400 of 4 and a part top profile of structure.In this structure, identical label is assigned to the corresponding parts of parts in the rearview of those and Fig. 1, and the descriptions thereof are omitted.In Figure 10, wherein newly provide a mobile test section 401.Suppose that the shown document detection part 105 of this figure is not provided in this image reader 400 according to execution mode 4.
This moves the inside that test section 401 is provided this shell 101 on the right in this drawing, and detects the rotation of a roller 104, and in other words, one of this image reader 400 is moved during this scan operation.This moves the encoder 402 that test section 401 comprises a rotation, gear 403 and 404.
The encoder 402 of this rotation is an incremental optical encoder, and it detects the angle of a rotation optically and high-resolution is arranged, and is not influenced by noise.The encoder 402 of this rotation comprises a rotatable input shaft 402a, at its rotating disk that otch that can be by light is directly upwards arranged and can rotate with this input shaft 402a, with be used for that light is transmitted into a light emitting members of this rotating disk and be used to receive a light-receiving member of the light of the otch by this rotating disk.
In the encoder 402 of this rotation, when this input shaft 402a rotates, this rotating disk correspondingly is rotated, when an otch of this rotating disk is positioned at an ad-hoc location, the light of the otch by this rotating disk is received by this light-receiving member, thus the anglec of rotation of this input shaft 402a can by from the position probing of this otch to.
In this image reader 400 according to execution mode 4, the encoder 402 of this rotation is used to detect an anglec of rotation as one of this image reader 400 mobile this input shaft 402a.Gear 403 is connected to the end of this input shaft 402a.Gear 404 is connected to an end 103a of a power transmission shaft 103, to mesh with this gear 403.That is, 104 torque of this roller is by this power transmission shaft 103, and gear 403 and gear 404 are sent to this input shaft 402a of the encoder 402 of this rotation.
Figure 11 is the block diagram of demonstration according to the electrical structure of this image reader 400 of execution mode 4.In this drawing, identical label be assigned to Fig. 3 and Figure 10 in the corresponding parts of those parts, and the descriptions thereof are omitted.In Figure 11, provide a data processing section 112B and a scanner part 405 to come this data processing section 112A shown in the alternate figures 3 and scanner part 111.
Further, in this data processing section 112B and scanner part 405, provide a reading control section 113B and a mobile test section 401 to substitute this mobile control division and divided 113A and document detection part 105.
Do not move when reaching a particular value when this image reader 400 moved along this document that does not show here in scan period and when this, shown this moves test section 401 and reads the mobile detection signal S3 that control section 113B exports one 1 pulse to this among Figure 11.This mobile control division divides 113B to detect the control that this document (not having to show) provides image reading here by move detection signal S3 according to this, and exports a drive signal S2 according to this testing result to this image reading part 107.
Below, the operation of this image reader 400 of 4 is described according to the embodiment of the present invention with reference to a shown flow graph of Figure 12.In Figure 10, under the situation that does not have near this document that does not show here at this image reader 400, open a power switch that does not show, this reading control section 113B shown among Figure 11 forwards this system's control to step SB1 (with reference to Figure 12), wherein by carry out with step SA1 (with reference to figure 4) in class of operation like operating provision (settings) the line number order of pictorial data, this system controls and forwards step SB2 to then.
In step SB2, this visual control section 113B moves test section 401 from this according to whether and has imported a mobile detection signal S3 and judge whether to detect of this image reader 400 and move.That is, in step SB2, judge whether to detect this document (not showing) according to whether having imported a mobile detection signal S3.
Under this situation, do not contact under the situation of this document this image reader 400 at this roller 104 when move a scanning direction, there is not signal to move output the test section 401 from this.So the judged result that this reading control section 113B identifies step SB2 is a "No", and repeats this identical judgement.
Then, this user is placed on this image reader 400 on this document in such mode, so that this image reading surface 101a this user by carrying out as above-mentioned identical operations is caught under the situation of this image reader 400 as shown in Figure 10, with condition is identical as shown in Figure 1 condition under this document of contact, read an image on this document.By this, roller 104,104 ... contact this document.
Then, when this user when this this document of upper edge, scanning direction slides this image reader 400 frictional force that works between (not showing) because roller and this document, roller 104,104 ... be rotated.By this power transmission shaft 103, gear 404 and 403, this moment is sent to this input shaft 402a, and pair of rollers 104,104 ... rotation respond, this input shaft 402a is rotated.
When an anglec of rotation of this roller 104 (input shaft 402a) reaches a special angle, in other words, when this image reader 400 on this scanning direction moves when reaching a particular value, move test section 401 from as Figure 11 as shown in this and export a 1-pulse and move detection signal S3.
This is read control section 113B and judges and detected this document, and the judged result that identifies step SB2 is "Yes", and this system's control forwards step SB3 to.In step SB3, this is read control section 113B and uses and the identical mode of step SA3 (with reference to figure 4), exports a drive signal S2 with a predetermined distance continuously to this image reading part 107.
After this step, by carrying out operation same as described above, when importing this drive signal S2 each time, row image data D1 on this document is outputed to a picture intelligence processing section 114 from this image reading part 107, and by this operation, this is read control section 113B and reads a row image that handled as this pictorial data D1 by this picture intelligence processing section 114, on this document continuously.
Then, this user this image reader 400 that on this scanning direction, slides, and a row image data D1 is input to this from this image reading part 107 through these picture intelligence processing sections 114 continuously and is read control section 113B.Like this, just carried out a scanning.During this slide, each time this image reader 400 be moved one specific when mobile, just move test section 1-pulse of 401 outputs and move detection signal S3 from this.Here, this translational speed that moves output cycle of detection signal S3 and this image reader 400 is corresponding, so when this speed uprised, this cycle shortened, and when this speed diminished, this cycle was elongated.
In step SB4, use the mode identical with step SB2 then, this is read control section 113B and moves one mobile (this document occurs or do not occur) that detection signal S3 detects this image reader 400 according to this.But, in this step SB4, this is read control section 113B and will compare with the time as a pre-defined threshold the used time when importing the mobile detection signal S3 of this front, and judges according to this result relatively.
In more detail, when this used time ratio as this time of a pre-defined threshold after a little while, this is read control section 113B and judges that having detected this judged result that moves (document) and identify step SB4 is "Yes", and forwards this system's control to step SB5.On the other hand, when this used time surpasses this time as a pre-defined threshold, this is read control section 113B and judges that not detecting this moves, and the judged result that identifies step SB4 is "No", and finishes to read this operation of an image.
Here, in step SB4, be because this user temporarily stops this scan operation with the reason of comparing as the time of a pre-defined threshold and why judge why according to this comparative result to a used time.Even this that has temporarily stopped this image reader 400 during this scan operation moves, and is less than under the condition of this threshold value in this time of moving hang-up, begin again, can continue this image reading then, and can not interrupt.
Under this situation, suppose that this image reader 400 moves along this document (not showing) continuously, and the used time when importing the mobile detection signal S3 of this front is less than the time as a pre-defined threshold, the judged result that this reading control section 113B identifies step SB4 is a "Yes", and this system's control forwards step SB5 to.
In step SB5, this read control section 113B use with step SA5 (with reference to figure 4) in the identical mode of mode, judge in step SB1, whether to have read the capable pictorial data D1 of defined amount (setting).Under this situation, when judging that this is read head office's number among the pictorial data D1 and is less than the line number order of this regulation, this judged result of reading that control section 113B identifies step SB5 is a "No", and this system's control forwards step SB3 to.This is read control section 113B and repeats the aforesaid operations sequence.Then, in step SB3, carry out the operation of reading the second row image data D1.
Here, in step SB5, when reaching the line number order of a regulation with this number of being read the corresponding row of pictorial data D1, it is "Yes" that this reading control section 113B identifies judged result, and finishes to read this operation of this image.
During above-mentioned this scan operation, when a user with this image reader 400 (roller 104,104, ...) separate with this document (not show) and when this image reader 400 taken away this that finish to read an image and operate, just stop roller 104,104 ... rotation.This is responded, just stop this power transmission shaft 103, the rotation of gear 403,404 and input shaft 402a.By this, after this, just do not move test section 401 and export a mobile detection signal S3 from as Figure 11 as shown in this.
So, in step SB4, when the used time when importing the mobile detection signal S3 of this front surpassed this time as a pre-defined threshold, this reads control section 113B, and to identify judged result be "No", and finish this scan operation.
As above-mentioned, by this image reader 400 according to execution mode 4, wherein provide this to move test section 401, and this read control section 113B judges reading according to a mobile detection signal S3 who moves test section 401 outputs from this beginning and end.Like this, do not need a user to operate a switch, with resemble in the conventional art begin or finish to read the instruction of an operation of this image, so use and the convenience of having improved actual use according to the identical mode of this image reader 100 of execution mode 1.
Although described this image reader 400 in detail according to embodiment of the present invention 4, this specific structure is not limited to execution mode 4, but knows that very modification and alternative structure that all that drops in this basic religious doctrine fully all are included among the present invention.This is described in supposition this image reader 400 according to execution mode 4 and has used the light rotary encoder 402 of this increment type as shown in Figure 10, but the type of this encoder is not limited to the above-mentioned type, and the magnetic rotary encoder of an increment type can be used as this rotary encoder 402.
The magnetic rotary encoder 402 of this increment type comprises a rotating disk with magnetic material being magnetized and is positioned near a position of this rotating disk and the MR (magnetoresistive sensor element) with resistance that the variation in a magnetic field that is produced according to this magnetic material changes on the circumference of its connection.In addition, the feature of the magnetic rotary encoder 402 of this increment type is that the size of this encoder is little and weight is light, and excellent environment resistance is arranged, and a long life-span and a high response frequency are arranged.So, when the magnetic rotary encoder 402 that uses an increment type, can reduced in size very expediently and weight reduction.
Referring now to Figure 10, Figure 13 and Figure 14 describe an image reader 500 according to embodiment of the present invention 5.Basic outward appearance and structure according to this shown image reader 400 of the basic outward appearance of this image reader 500 of execution mode 5 and structure and Figure 10 are identical, but, provide a document detection part 105 (with reference to the rearview of figure 1) among shown in this drawing this image reading surface 101a.
Figure 13 is the block diagram of demonstration according to the electrical structure of this image reader 500 of execution mode 5.In this drawing, identical label is assigned to the corresponding parts of parts among those and Figure 11, and the descriptions thereof are omitted.In Figure 13, a data processing section 112C and a scanner part 501 are provided, substitute shown this data processing section 112B of Figure 11 and scanner part 405.
In addition, in shown this data processing section 112C of Figure 13, provide one to read control section 113C, substituted shown this reading control section 113B of Figure 11, and a document detection part 105 (with reference to Figure 10) is provided in this scanner part 501 again.
Shown this of Figure 13 read control section 113C according to from a document detection signal S1 of these document detection part 105 inputs with discern the beginning and the end of the image of reading a document (not have demonstration) from this mobile detection signal S3 who moves test section 401 inputs.
Below, with reference to a shown flow graph of Figure 14 operation according to this image reader 500 of execution mode 5 is described.In Figure 10, under the situation of a position that is not placed on close this document (not showing) at this image reader 500 (this document detection part 105), when opening a power switch that is not shown, shown this reading control section 113C of Figure 13 forwards this system's control to step SC1 (with reference to Figure 14), wherein by carrying out and the operation identical operations of step SA (with reference to figure 4) the line number order will being read as pictorial data of having stipulated (settings), this system controls and forwards step SC2 to then.
In step SC2, this visual control section 113C judges whether this document detection part 105 detects a document, in other words, whether has imported a document detection signal S1 from this document detection part 105.Under this situation, when this document detection part 105 is not near this document as shown in Figure 10, just there is not document detection signal S1 from these document detection part 105 outputs.So the judged result that this reading control section 113C identifies step SC2 is a "No", and repeats this identical judgement.
This user is placed on this image reader 500 on this document in such mode then, so that this image reading surface 101a is in order to read an image on it, this user catches this document of contact under the situation of this shown image reader 500 of Figure 10.By this operation, when this document detection part 105 during near this document, a document detection signal S1 is outputed to this and is read control section 113C from this document detection part 105.
The judged result that this reading control section 113C identifies step SC2 is a "Yes", and this system's control forwards step SC3 to.In step SC3, by carry out with step SB2 in operation (with reference to Figure 12) identical operations, this is read control section 113C and moves test section mobile detection signal S3 of 401 inputs according to whether from this and judge whether to detect of this image reader 500 and move.When this judged result was "No", this system's control turned back to step SC2, and this reads control section 113C repetition aforesaid operations sequence.
That is, in step SC3, after importing this document detection signal S1, judge whether to detect this document (not showing) according to whether having imported a document detection signal S3.
Then, passing through execution and aforesaid operations identical operations, this user catches under the situation of this image reader 500 as shown in Figure 10, under the condition identical with the shown condition of the front view of Fig. 1, this user contacts this document with this image reading surface 101a, and on this scanning direction, come along this document this reader that slides, to read an image on it.
By this operation, roller 104,104 ... be rotated because of the frictional force between roller and this document (not having to show), and this rotation is responded, this input shaft 402a uses the mode identical with aforesaid way to be rotated.Then, when an anglec of rotation of roller 104 (input shaft 402a) reaches a special angle, in other words, when this image reader 500 mobile on this scanning direction reaches a setting, move test section 1-pulse of 401 outputs from shown this of Figure 13 and move detection signal S3.
By this feature, the judged result that this reading control section 113C identifies step SC3 is a "Yes", and this system's control forwards step SC4 to.In step SC4, this read control section 113C with the interval of a regulation to the continuous drive signal S2 of output of this image reading part 107.As a result, by execution and aforesaid operations identical operations, when importing this drive signal S2 each time, from the row image data D1 of this image reading part 107 on these picture intelligence processing section 114 these documents of output.Then in step SC4, this is read control section 113C and reads that handle and be imported into wherein a row image data D1 by this picture intelligence processing section 114.So just carried out a scanning.
In step SC5, this is read control section 113C and judges whether this document detection part 105 has detected this document then.Here, when this image reader 500 slides this document, because this document detection part 105 is near this document, so read document detection signal S1 of control section 113C output from this document detection part 105 to this.
Scanning has been carried out in this expression, and when from this document detection part 105 when this reads document detection signal S1 of control section 113C output, the judged result that this reading control section 113C identifies among the step SC5 is a "Yes", and system's control forwards step SC5 to.In step SC6, this is read control section 113C and judges whether read the capable pictorial data D1 of regulation (setting) number in step SC1 by execution and the operation identical operations among the step SA5 (with reference to figure 4).That is, when this judged result was "No", this reads control section 113C made this system's control turn back to step SC4, and repeats the aforesaid operations sequence.When this judged result was "Yes", this was read control section 113C and finishes this scan operation.
During above-mentioned this scan operation, when a user separates this image reader 500 (document detection part 105) and this image reader 500 is taken away this operation that finishes to read an image with this document, just stop from this document detection part 105 this document detection signal of output S1, so the judged result that this reading control section 113C identifies among the step SC5 is a "No", and finishes to read this operation of an image.
As above-mentioned, by above-mentioned image reader 500 according to embodiment of the present invention 5, this is read control section 113C and uses this document detection part 105 and this to move beginning and the end that image reading is identified in test section 401.Like this, do not need a user to operate a switch resembling in the conventional art, provide beginning or technology and read the instruction of an operation of this image, so use and the convenience of having improved actual use according to the identical mode of the mode of this image readers 100 of execution mode 1 and 4 and 400.
Especially, by above-mentioned image reader 500 according to embodiment of the present invention 5, according to whether having detected from this document detection part 105 these document detection signal S1 of input and having moved of a mobile detection signal S3 of test section 401 inputs from this and come regulation to begin to read a condition of this image with condition, so can avoid respectively according to this image reader 100 of execution mode 1 with according to the following misoperation of supposing in this image reader 400 of execution mode 4, and correspondingly improve the precision of image reading.
Promptly, in above-mentioned this image reader 100 according to execution mode 1, because when the time from document detection signal S1 of these document detection part 105 inputs, just begin to read this image, even so by faulty operation or do not note, this document detection part 105 also can begin to read this image when not being any material of document P (with reference to Figure 1A), and this is disadvantageous.

With reference to Figure 10, Figure 15 and Figure 16 describe an image reader 600 according to embodiment of the present invention 6.Figure 15 is the block diagram of demonstration according to the electrical structure of this image reader 600 of execution mode 6.In this drawing, identical label is assigned to the corresponding parts of parts among those and Figure 13, and the descriptions thereof are omitted, in Figure 15, provides a data processing section 112D to substitute shown this data processing section 112C of Figure 13.Outward appearance and structure according to this shown image reading 500 of the outward appearance of this image reader 600 of execution mode 6 and structure and Figure 10 are identical.
Further, in this data processing section 112D, provide a reading control section 113D to substitute shown this reading control section 113C of Figure 13, and newly provide a power control section to divide 601.Although it is identical with the operation of above-mentioned reading control section 113C (with reference to Figure 13) to read this operation of an image (scan operation), being added to this function of reading control section 113D is to divide 601 reports whether to import the information of a document detection signal S1 and a mobile detection signal S3 to this power control section.
This power control section divides 601 to control each part (this document detection part 105 in a scanner part 501 according to this input state reading a document detection signal S1 among control section 113D and a mobile detection signal S3, this image reading part 107 and mobile test section 401) power supply.Here, this power control section is divided and has been comprised a timer internal that is used to count a time in 601.
In more detail, in during open a power switch (do not have show) is input to this image of reading (scanning) of reading control section 113D to a document detection signal S1 stand-by time, this power control section is divided 601 controls that intermittent power supply is provided, come with for example, 0.5 interval each part (this document detection part 105 in this scanner part 501 of second, this image reading part 107 and mobile test section 401) carry out intermittent power supply.
Further, read control section 113D in again during this reads the stand-by time of an image of reading (scanning) of a document detection signal S1 of control section 113D input stopping to be input to this from this document detection signal S1, this power control section is divided 601 controls that intermittent power supply is provided, come with for example, 0.5 interval each part (this document detection part 105 in this scanner part 501 of second, this image reading part 107 and mobile test section 401) carry out intermittent power supply.That is, in above-mentioned intermittent power supply control period, repeat ON/OFF,, closed power again at next 0.5 second so that this power was opened 0.5 second.
In addition, reading image reading commencing signal of control section 113D input from this to again in this reads operating period of this image of reading (scanning) of an image reading end signal of control section 113D input, this power control section is divided 601 controls that continuous power supply is provided, and comes continuously each part in this scanner part 501 to power.
Here, why divide the control of 601 execution intermittent power supplies and the reason of the control of power supply continuously to be by this power control section, because in during one, unnecessary power loss has been reduced, only be different from during this when this document detection part 105 and this image reading part 107 actual that be used, detect a document during.
Describe according to the power in this image reader 600 of execution mode 6 below with reference to Figure 16 and to control.In Figure 15, under the situation that does not have at this image reader 600 (document detection part 105) near this document (not having to show), when opening power switch that is not shown, this power control section divides 601 to forward the control of this system to Figure 16 shown step SD1, substitution in the parameter i of an inside " 1 ", and forward the control of this system to step SD2.
In step SD2, this power control section divides 601 by beginning each part (this document detection part 105 in this scanner part 501, this image reading part 107, with mobile test section 401) power and open this power, and this system's control forwards step SD3 to then.
In step SD3, this power control section divides 601 to judge whether a document detection signal S1 has been imported into this and has read control section 113D, in other words, judge the operation whether this document detection part 105 has detected a document (not showing) and whether begun to read this image.Under this situation, suppose that this document detection signal S1 is not imported into this and reads control section 113D, it is "No" that this power control section is divided 601 judged results that identify among the step SD3, and this system's control forwards step SD11 to.
In step SD11, this power control section divides 601 to identify the operation that does not begin to read this image, and by finishing each part (this document detection part 105 in this scanner part 501, this image reading part 107 and mobile test section 401) power and close this power.Like this, the power consumption vanishing of each part in this scanner part 501.In addition, this power control section divides 601 to be provided at the control of closing power among the step SD11, and begins simultaneously to carry out gate time by this timer internal (not showing).
Then, when this time that obtains by this timer internal of counting, identify and from step SD11, close power and passed through later on 0.5 second, after forwarding the control of this system to step SD2, this power control section is divided 601 sequence of operation and the substitutions " 1 " in this inner parameter i among the execution in step SD11 again.In step SD2, by carrying out and the aforesaid operations identical operations, this power control section divide 601 again each part in this scanner 501 power, and this system's control forwards step SD3 to.
In step SD3, this power control section divides 601 to judge whether a document detection signal S1 has been imported into this and has read control section 113D.Suppose that this judged result is a "No", this system's control forwards step SD11 to, and as above-mentioned this power control section divides 601 each part that finishes in this scanner 501 to power, and after 0.5 second stand-by time has been crossed, again the sequence of operation among the execution in step SD1.Then, this power control section is divided 601 controls that intermittent power supply is provided, carry out intermittent power supply with interval each part in this scanner part 501 of 0.5 second, be imported into this up to document detection signal S1 in step SD3 and read control section 113D.
Here, when a user in order to carry out this operation of reading this image, and with this document detection part 105 near these documents when (not showing), a document detection signal S1 is outputed to this and is read control section 113D from this document detection part 105.By this, it is "Yes" that this power control section is divided 601 judged results that identify among the step SD3, and this system's control forwards step SD4 to.
In step SD4, this power control section is divided 601 substitutions " 0 " in this inner parameter k, and this system's control forwards step SD5 to then.In step SD5, this power control section divides 601 to make this timer internal begin to count a time, and system's control forwards step SD6 to.In step SD6, this power control section divides 601 to wait for (standby) 1 millisecond of time, and this system's control forwards step SD7 to then.
In step SD7, this power control section divides 601 to judge whether a mobile detection signal S3 has been imported into this and has read control section 113D.Under this situation, suppose because this image reader 600 still remains static, so this moves detection signal S3 and is not imported into this reading control section 113D, it is "No" that this power control section is divided 601 judged results that identify among the step SD7, and this system's control forwards step SD12 to.That is, under this situation, this user does not move this image reader 600 at this this document of upper edge, scanning direction.。
In step SD12, this power control section divides 601 to judge whether inner parameter k is " 0 ", and when under this situation, when inner parameter k was " 0 ", identifying judged result was "Yes", and this system's control forwards step SD13 to.In step SD13, this power control section divides 601 to power powered-down by each part that stops in this scanner part 501, and this system's control forwards step SD14 to then.
Promptly, under this situation, because since this power switch of opening this image reader 600 (not showing) rises, the time that this image reader 600 stops is more than an official hour phase, so when judged result when not beginning image reading, each part that stops in this scanner part 501 is powered.
Then, in step SD14, this power control section divides 601 this inner parameter i (=1) increased by 1 to " 2 ", and this system's control forwards step SD15 to.In step SD15, this power control section divides 601 to judge whether this inner parameter i is " 3 ".In other words, in step SD15, judge whether the dwell time of this image reader 600 has surpassed a stipulated time.Under this situation, when this inner parameter i was 2, it was "No" that this power control section is divided 601 judged results that identify among the step SD15, and this system's control forwards step SD17 to.
In step SD17, this power control section divides 601 to wait for that (standby) 0.5 second and system's control turn back to step SD2.In step SD2, each part in this scanner part 501 is powered again, and this system's control forwards step SD3 to.In the same manner, repeat the aforesaid operations sequence.
On the other hand, when this inner parameter i was " 3 " in step SD15, this power control section divides 601, and to identify judged result be "Yes", and this system's control turns back to step SD1, substitution " 1 " in this inner parameter i again, and repeat the aforesaid operations sequence.But before this system's control turned back to step SD1, this power control section divided 601 to wait for 5 seconds in step SD16.This waits for that this image reader 600 of expression is placed on this document surfaces the preceding paragraph time and does not have the state of execution to the scanning of this document.
Then, when passing through execution and aforesaid operations identical operations, the roller 104 that Figure 10 is shown, 104, ... contact under the state of this document, this user slides this image reader 600 when reaching a predetermined distance along this document on a scanning direction, move test section 1-pulse of 401 outputs from shown this of Figure 15 and move detection signal S3 and read control section 113D to this.
By this operation, it is "Yes" that this power control section is divided 601 judged results that go out among the step SD7 by the aforesaid operations recognition sequence, and this system's control forwards step SD8 to.In step SD8, this power control section divides 601 (under this situation, k-0) increase by 1, and this system's control to forward this inner parameter k to step SD9.In step SD9, this power control section divides 601 to judge whether this inner parameter k is " 8 ".When under this situation, when this inner parameter k was " 1 ", this power control section divides 601, and to identify judged result be "No", and this system's control forwards step SD10 to.
In step SD10, this power control section divides 601 to judge whether the result of this timer internal time of counting reaches 4 seconds, and supposition is under this situation, the result of this timer time of counting is less than 4 seconds, it is "No" that this power control section is divided 601 judged results that identify among the step SD10, and this system's control turns back to step SD6.Then, repeat the aforesaid operations sequence.
Here, in step SD8, suppose that this inner parameter k is " 8 ", it is "Yes" that this power control section is divided 601 judged results that identify among the next procedure SD9, and this system's control forwards step SD18 to.In step SD18, this power control section divides 601 to read a judged result among control section 113D reporting step SD9 to this, and this system's control forwards step SD19 to then.
By this operation, this is read control section 113D and begins to export a drive signal S2 by carrying out with the aforesaid operations identical operations to this image reading part 107, and read from the digital map image data D1 of delegation of this image reading part 107 through these picture intelligence processing section 114 inputs, like this, just carried out this operation of reading an image (line scanning).
In step SD19, this power control section divide 601 by carry out with step SD3 in the operation identical operations judge whether a document detection signal S2 has been imported into this and has read control section 113D.Under this situation, suppose and continue the operation that this reads an image, so this document detection signal S1 has been imported into this and has read control section 113D, it is "Yes" that this power control section is divided 601 judged results that identify among the step SD19, and this system's control turns back among the step SD18, in step SD18, continue 1 line scanning operation.
When the judged result among the step SD19 by as above-mentioned when being identified as "Yes", in other words, when continuing to carry out this operation of reading an image, just divide each part that continues in this scanner part 501 under 601 the control to power, so just carried out the control that continuous power is powered in this power control section.
Here, when this user comes this image reader 600 and this document branch when finishing to read this operation of an image, just stop from document detection signal S1 of this document detection part 105 outputs.By this operation, it is "No" that this power control section is divided 601 judged results that identify among the step SD19, and this system's control forwards step SD11 to.In step SD11, this power control section divides 601 each part that stopped in 0.5 second in this scanner part 501 to power, and this system's control turns back to step SD1 again.Then, repeat the aforesaid operations sequence.
On the other hand, in step SD10, when the result of this timer internal time of counting reached 4 seconds, this power control section divides 601, and to identify judged result be "Yes", and this system's control forwards among the step SD11.In step SD11, this power control section divides 601 each part that stops in this scanner part 501 to power, and after a stand-by time of 0.5 second, this system's control turns back to step SD1 again.
As above-mentioned, by using this image reader 600 according to execution mode 6, provide this power control section to divide 601, provide power supply control with the state according to image reading of allowing to, make it switch to continuous power supply control or switch to intermittent power supply control from continuous power supply control from intermittent power supply control to this scanner part 501.So, compare with this situation of in all time, all powering to this scanner part 501, can reduce power consumption.

Below, will operation according to this image reader 700 of embodiment of the present invention 7 be described with reference to the shown time flow graph of Figure 20.Here, mobile detection signal S3 is that shown this moves a signal of test section 401 outputs from Figure 19, rotation when the shown roller 104 of Figure 17, in other words, this image reader 700 on this scanning direction one moves when reaching a setting, and this moves detection signal S3 and is used as a 1-pulse signal output.
In each later drive cycle of push switch 704, a drive signal S2 reads the 1-pulse signal that control section 113E outputs to this image reader 700 continuously from this.Shown label " 1 " arrives the pictorial data D1 of " 9 " expression first row to the 9th row among one row image data D1 of this document that this image reading part 107 reads (not showing) and the figure.
Further, the data that pictorial data D1 shown, that be quantized is quantized by this picture intelligence processing section 114 among Figure 20, shown label " 1 " arrive " 9 " and is that pictorial data D1 shown " 1 " arrives " 9 " corresponding among the figure.
When reading this image, this user at first is placed on this image reader 700 a beginning reading position on the shown document P of Figure 18, so that its image reading surface 101a (with reference to Figure 17) contacts this document P.By this operation, the roller 104,104 that Figure 17 is shown ... P contacts with this document.
Then, this user presses this console switch 704 and once opens power source.By this operation, a signal of opening is outputed to this and is read control section 113E from this shown console switch 704 of Figure 19, and powers to each part of this device.Then, this reading control section 113E visits this image data memory 701 and checks whether a free space is arranged, and when this image data memory 701 has a free space, the LED703 transmitting green light, when this image data memory 701 does not have free space, the LED703 red-emitting.Under this situation, supposing has a free space in this image data memory 701, so LED803 is with regard to transmitting green light.
Then, this is read control section 113E and begins to export a drive signal S2 at the shown moment t0 of Figure 20 to this image reading part 107, and whether monitoring has imported a mobile detection signal S3 in this drive cycle T that rises since this drive signal of output S2.By this operation, just drive this image reading part 107, and read the row image on this document P, and the pictorial data D1 of first row is output to this picture intelligence processing section 114.
Then, the pictorial data D1 of this first row is quantized by this picture intelligence processing section 114, and is imported into this reading control section 113E.By this operation, this is read control section 113E this first pictorial data D1 that goes is kept in this buffer storage, up to wherein imported next line (being one second row) pictorial data D1 under this situation.
This user by press this console switch 705 and on the direction represented by arrow Z2, along this document P slide grabbing by this user, be displayed on this image reader 700 among Figure 18, begin a scan operation, by this operation, roller 104,104, ... (with reference to Figure 17) rotates because of the frictional force between roller and this document P, this makes an input shaft of the shown flexible blocking device 402 of Figure 17 be rotated and drive by aforesaid operations, and begins to detect of this image reader 700 and move.Then, at the shown moment t1 of Figure 20, when being moved test section 401 from this, a mobile detection signal S3 is input to this when reading control section 113E, this reading control section 113E identifies this image reader 700 and has moved the corresponding part with delegation, and when exporting next drive signal S2 at moment t6, carry out expression transmits Interrupt Process from data to this image data memory 701.That is, this is read control section 113E and reads the pictorial data D1 that first row is quantized at this moment t6 from this buffer storage (not having to show), and these data are sent to this image data memory 701.By this operation, the pictorial data D1 that is quantized of first row is stored in this image data memory 701.
After this step, when importing a drive signal S2 each time, in other words, to each drive cycle T, the pictorial data of the pictorial data D1 of second row and other row thereof is output to this picture intelligence processing section 114, and when importing this pictorial data D1 that delegation quantized by this picture intelligence processing section 114 each time, this read that control section 113E will be stored in that previous in this storage buffer be quantized that pictorial data D1 is updated to new input with the pictorial data D1 that quantizes.
Whether this reading control section 113E monitoring has imported this in this drive cycle T moves detection signal S3, and by handle the interruption that a number is reportedly sent when importing this signal, a row image data D1 that will be stored in this buffer storage is sent to this image data memory 701.
In the shown example of Figure 20, at moment t7, t8, t9 carry out the Interrupt Process that this data transmit, and with second row, fourth line and the 7th row are quantized pictorial data D1 accordingly and are sent in this image data memory 701.By aforesaid operations, the pictorial data D1 that is quantized is kept in this image data memory 701 continuously with a behavior unit.
Here, in the shown example of Figure 20, in a drive cycle T, import this at moment t2 altogether with moment t3 and move detection signal S3 twice.When the translational speed of this image reader 700 surpassed the image reading speed of this image reader 700, this phenomenon just took place.Under this situation, when moment t3 input was moved detection signal S3 as this of a flop signal, this read the Interrupt Process that control section 113E actual figure reportedly send.
On the other hand, very low or this image reader 700 stops just not import a mobile detection signal S3 when mobile in a drive cycle T when the translational speed of this image reader 700.Under these situations, this is read control section 113E and only will be stored in the previous input in this buffer storage and quantize the quantification pictorial data D1 that pictorial data D1 is updated to new input, but, these data are not sent to this image data memory 701.
Then, suppose that this shown image reader 700 of Figure 18 slides into this along this document P from this reading starting position and reads end position, this operation that this user once finishes to read an image by this shown console switch 705 of Figure 19.By this operation, this is read control section 113E and identifies this image reading operation that is through with, thereby finishes data are sent to the processing of this image data memory 701.As a result, the multirow quantification pictorial data D1 that obtains in the operation of an image of one first reading is stored in this image data memory 701 as the pictorial data of one first document P.
After this step, when again by this console switch 705, carry out second operation of reading an image by carrying out, and read the multirow that obtains in the operation of an image one second and quantize pictorial data D1 and be stored in this image data memory 701 as the pictorial data of one second document P with the aforesaid operations identical operations.
In this operating period of reading an image, this reads the free space that control section 113E monitors this image data memory 701.So when this free space used up, this was read control section 113E and just controls, the color that makes the light that LED703 launches from green become red.By this operation, this User Recognition goes out this image data memory 701 does not have free space, in other words, can not carry out an image reading operation.
As above-mentioned, by using this image reader 700 according to embodiment of the present invention 7, quantize pictorial data D1 because provide this image data memory 701 to preserve therein, so this image reader 700 can be counted as an independent device, when reading image, do not need to link to each other with other computer by cable.
So, by using above-mentioned this image reader 700, eliminated in conventional art according to execution mode 7, become the difficulty of a trouble reading this cable when visual, so improved adaptability and the operability handled.
Further, by using above-mentioned this image reader 700 according to execution mode 7, because used the structure that realizes an independent type, so compare with the image reader of traditional type that inside is integrated with the main body of a computer, this device can reduce size.

Figure 39 shows two ordinary constructions of a tilt detection part that is provided in this shell 1301.This tilt detection part 1340 detects the inclination of this image reader 1300, and promptly whether this image reader 1300 is maintained at this horizontal attitude or is maintained at this perpendicular attitude.The top view of Figure 39 is to show when this image reader 1300 is maintained at this horizontal attitude, a common lateral plan of a state of this tilt detection part 1340, its bottom view is to show when this image reader 1300 is maintained at this perpendicular attitude a common lateral plan of a state of this tilt detection part 1340.
Be described with reference to Figure 40 the structure of this tilt detection part.In Figure 40, identical label be assigned to Figure 39 in the corresponding parts of those parts.This shown tilt detection partly comprises 1342, one rotating bars 1343 of 1341, one permanent magnets of a lead switch and a rotating drive shafts 1344 among this figure.This lead switch 1341 is switches of an induced field, and comprises a glass tube 1341a, one first ferromagnet lead 1341b, a first make contact 1341e, one second ferromagnet lead 1341f and one second contact point 1341i.
In above-mentioned this lead switch 1341, this first ferromagnet lead 1341b and this second ferromagnet lead 1341f along one of this glass tube 1341a radially, and comprise and form a nemaline ferromagnetic material.A marginal portion of each among ferromagnet lead 1341b and the 1341f is crooked, and is shielded to the inside of this glass tube 1341a, so that two marginal portions of this of these lines are positioned at close position mutually.This first make contact 1341e adheres to the marginal portion of this first ferromagnet lead 1341b, and this second contact point 1341i adheres to the marginal portion of this second ferromagnet lead 1341f.In this lead switch 1341, when do not work along the longitudinal direction in an external magnetic field, because the elastic force that this first ferromagnet lead 1341b and this second ferromagnet lead 1341f are produced, this first make contact 1341e and this second contact point 1341i remain on position spaced apart from each other.
On the other hand, when this external magnetic field when the longitudinal direction of this first ferromagnet lead 1341b and this second ferromagnet lead 1341f works, the polarity of another marginal portion 1341d of this first ferromagnet lead 1341b is " S ", and the polarity of this first make contact 1341e is " N ".Similarly, the polarity of another marginal portion 1341h of this second ferromagnet lead 1341f is " N ", and the polarity of this second contact point 1341i is " S ".So when work in this external magnetic field, this first make contact 1341e and this second contact point 1341i attract each other and are in contact with one another.
This permanent magnet 1342 is used for adding this external magnetic field according to an attitude of this image reader 1300, and it adheres to this pointed portion of rotatable excellent 1343, and this rotatable excellent 1343 can be along the rotation of the represented direction of the arrow Q among this figure.This another marginal portion of rotatable excellent 1343 adheres on this rotatable power transmission shaft 1344.One first stop component 1345 adheres to a position near this lead switch 1341, and limits this permanent magnet 1342 and rotate along the anticlockwise among the figure.One second stopper parts 1346 adhere to a position near this lead switch 1341, and limit this permanent magnet 1342 along the rotation clockwise among the figure.
In Figure 40, because the restriction of this first stop component 1345, so when this permanent magnet 1342 is positioned at the represented position of solid line, promptly when this image reader 1300 is maintained at as this horizontal attitude as shown in the top view of Figure 39, work in the external magnetic field that this permanent magnet 1342 is produced, and this first make contact 1341e is in contact with one another with this second contact point 1341i.
In Figure 40, because the restriction of this second stop component 1346, so when this permanent magnet 1342 is positioned at one two one position of ruling represented, promptly when this image reader 1300 is maintained at as this perpendicular attitude as shown in the bottom view of Figure 39, this external magnetic field that this permanent magnet 1342 is produced is inoperative, so this first make contact 1341e and this second contact point 1341i keep being spaced from each other.
With reference now to Figure 42 and Figure 43, a position according to a center of gravity of this image reader 1300 of execution mode 13 is described.Among Figure 42 and Figure 43 each is the common lateral plan of explanation according to a size (position of a center of gravity) of this image reader 1300 of execution mode 13.In these figure, identical label be assigned to Figure 41 in the corresponding parts of parts.
At first, this image reader 1300 according to execution mode 13 is designed, so that application point N1, N2 is positioned at the position lower than the position of centre of gravity of this image reader 1300, and the height of application point S is less than a width W of this image reader 1300.The purpose of using this structure is to make when this shown among this figure image reader 1300 to move on represented this direction along arrow Z1 respectively and along arrow Z2 on represented this direction when mobile, and the moment that is produced on this represented on this direction represented along arrow M1 with along arrow M2 direction is less.Promptly, when a user holds this shell 1301, this user's opposing thumb is touched the operating surface of this surperficial 1301f of this image reader 1300, when other finger touched one rear surface 1301m, application point N1 that Figure 42 is shown and N2 laid respectively at the intermediate point of a height of this thumb and an intermediate point of other finger.
Should be noted that the distance between the intermediate point of an intermediate point of an adult thumb and other finger is 150 millimeters generally.Here, in this shell 1301, a length X and a length Y on this short transverse on this Width have been defined.This length X on this Width with equate to the distance the 1301m of this rear surface from this operating surface 1301f, and this length Y on this short transverse with equate upward to the distance between the top surface of this shell 1301 from application point N1 and N2.Further, by highly being deducted at this length Y on this short transverse, of this shell 1301 just can calculate the height upward to the application point S between application point N1 and the N2 from a document P.
In definition as above, when of application point highly is positioned at the high position of a position of centre of gravity than this image reader 1300, during a scan operation, in this image reader 1300, produce along on this represented direction of arrow M1 or along the moment on this represented direction of arrow M2 among this figure, so this image reader 1300 becomes inclination.So, by designing this image reader 1300 like this, so that a form of its crosscut section satisfies application point N1 and N2 this condition (be called first condition) lower than the position of center of gravity L, just can forbid because the inclination of this image reader 1300 that above-mentioned moment produced.
Here, a height supposing this shell 1301 is H, a width of this device is W, distance between the intermediate point of an intermediate point of a thumb and other finger is F, the height of its center of gravity is G, and the height S that satisfies the application point of this first condition represents with following equation (1):
S＝((2H+W)-F)/2(1)
Then, by with particular value, 67 millimeters is a height H of this shell, 28 millimeters is a width W of this device, 150 millimeters be between the intermediate point of an intermediate point of a thumb and other finger apart from F, this equation of substitution (1), the height S that just obtains this application point is 6 millimeters.Here, suppose that the height G of center of gravity equates with this outer cover height H half (H/2), so the height of this center of gravity is 33.5 (=67/2) millimeters.So, when using above-mentioned size, satisfy height of C.G. G this first condition, so can forbid producing moment or this image reader run-off the straight greater than a height S (33.5＞6) of application point.But, even this first condition above having satisfied when using shown this size of Figure 43, still produces moment (perhaps tilting).Here, the length X that Figure 43 is shown ', a length Y ' on this short transverse, a width W ' of this device, with this length X on one of this application point height S ' and this shown Width of Figure 42, this length Y on this short transverse, this height S of this width W of this device and this application point is corresponding.
In this shown image reader 1300 of Figure 43, the size of using satisfies this height S ' of this application point this first condition less than height of C.G. G ', but this height S ' of this application point is than this width W ' height of this device, so produce along on this represented direction of arrow M1 or along the moment on this represented direction of arrow M2.On the contrary, in Figure 43, when this height S ' that satisfies this application point this condition than this width W ' low (being called second condition later on) of this device, when satisfying this first condition (this height S ' of this application point is less than height of C.G. G ') simultaneously, just can not produce along on this represented direction of arrow M1 or along the moment on this represented direction of arrow M2 (perhaps tilting).
So, be designed to size according to this image reader 1300 of embodiment of the present invention 13 and satisfy this first condition and second condition simultaneously.

＜data communication 〉
Figure 66 is the circuit diagram that an external device (ED) (computer 1360) of demonstration and this image reader 1300 carries out the operation of data communication.In this drawing, suppose that this computer 1360 partly is electrically connected with this serial i/F.As this above-mentioned connection status in, this computer 1360 is visited this DRAM1356 through this serial i/1321, one DMA I/F of F part parts 1352 and a bus B U.This pictorial data is read out from this DRAM1356 and through this bus B U, this DMA I/F part 1352 and this serial i/F part 1321 are sent to this computer 1360.
On the contrary, when this pictorial data by when this computer 1360 transmits, this pictorial data is written to this DRAM1356 through this serial i/F part 1321 and this DMA I/F part 1352.
Suppose another example that is electrically connected to this USBI/F part 1359 as this external device (ED) that does not show among this figure, this external device (ED) is through this USB I/F part 1359, this bus B U, this DMA I/F part 1352 and this bus B U visit this DRAM1356.This pictorial data is read out from this DRAM1356 and through this bus B U, this DMA I/F part 1352, this bus B U and this USB I/F part 1359 are sent to this external device (ED) (not showing).On the contrary, when this pictorial data by when this external device (ED) transmits, this pictorial data is through this USB I/F part 1359, this bus B U, this DMA I/F part 1352 and this bus B U are written to this DRAM1356.
In Figure 66, this computer 1360 (a perhaps external device (ED) (not showing)) directly is connected through this DMA I/F part 1352 with this DRAM1356, and not through this MPU1350, but these two parts can be interconnected on together but pass through this MPU1350 without this DMA I/F part 1352.
Below, with reference to Figure 20, Figure 31, Figure 39, Figure 40, Figure 41 and Figure 45 describe the operation of above-mentioned this image reader 1300 according to execution mode 13 to Figure 50.
When reading one when visual, a user at first presses this shown mains switch 1315 of Figure 31.By this operation, each part in this device is powered.Then, this user is placed on the document P one with this image reader 1300 and reads the starting position, so that this image reading surface 1301a contacts this document P.By this operation, judge home roll 1304, the first additional rollers 1305, contact this document with the second additional roller 1306.Here, suppose that this image reader 1300 is placed on this document P with this horizontal attitude as shown in the top view of Figure 39.So this permanent magnet 1342 is arranged on the shown position of the solid line of Figure 40.That is, " S " utmost point of permanent magnet 1342 contacts this first stopper parts 1345, and parallel with this lead switch 1341.
By this operation, work along the longitudinal direction of this first ferromagnet lead 1341b and this second ferromagnet lead 1341f in the magnetic field that this permanent magnet 1342 is produced.Here, in this first ferromagnet lead 1341b, this first make contact 1341e becomes " N " utmost point, and another marginal portion 1341d becomes " S " utmost point.On the other hand, in this second ferromagnet lead 1341f, another marginal portion 1341h becomes " N " utmost point, and this second contact point 1341i becomes " S " utmost point.
So the polarity of this first make contact 1341e is opposite with the polarity of this second contact point 1341i, thus an attraction produced, and this first make contact 1341e is in contact with one another with this second contact point 1341i.So, export a skew detection signal S7 from this tilt detection part 1340 that Figure 45 is shown to this data processing section 1400, and this pictorial data direction is corrected the inclination (attitude) that part 1430 identifies this image reader 1300.That is, this pictorial data direction is corrected part 1430 and is identified top view and this shown horizontal attitude of Figure 49 that this image reader 1300 is maintained at Figure 39.
When this image reader 1300 is maintained at shown this perpendicular attitude of the bottom view of Figure 39 and Figure 49, this shown permanent magnet 1432 of Figure 40 is arranged in the represented position of a chain-dotted line of this figure, so do not work being parallel on the direction of this lead switch 1341 in this magnetic field.Under this situation, because this first make contact 1341e and this second contact point 1341i are spaced from each other, so do not export this skew detection signal S7.So this pictorial data direction is corrected part 1430 and is identified bottom view and this shown perpendicular attitude of Figure 49 that this image reader 1300 is maintained at Figure 39.When being placed on shown this document P of Figure 41 one, this image reader 1300 reads the starting position, so that this image reading surface 1301a is when contacting this document P, this document P is partly detected by this shown document detection of Figure 45, and reads document detection signal S1 of control section 1410 outputs from this document detection part 1307 to this.
By this operation, this reads control section 1410 beginnings to this image reading part drive signal S2 of 1330 outputs and shown this drive signal S2 of output Figure 20.Then, this is read control section 1410 checks and whether imported a mobile detection signal S3 in a drive cycle T.Like this, just drive this image reading part 1330, and read the row image on this document P, and export shown this row 1 pictorial data D1 of Figure 20 to this picture intelligence processing section 1420 from this image reading part 1330.
Then, this shown A/D conversion portion 1421 of Figure 46 will be converted to numerical data from this pictorial data D1 (analogue data) of these image reading part 1330 inputs, and this numerical data is outputed to this line data retaining part 1422 and outputs to this density histogram generation part 1423.
This line data retaining part 1422 keeps the numerical data of delegation.This density histogram produces part 1423 according to the density histogram that produces each point from the dateout (numerical data) of this A/D conversion portion 1421, and the data of this density histogram are outputed to this threshold value generation part 1424.
This threshold value produces part 1424 and calculates a peak value of a white colour and a peak value of a black color according to this density histogram, and calculates a threshold value TH between this peak value of this peak value of a white colour and a black color then.This numerical data and this threshold value TH that this quantized segment 1425 will be stored in this line data retaining part 1422 compare, and read control section 1410 to this and export the quantized result that conduct is quantized this numerical data of pictorial data D3 (it is capable that shown this of Figure 20 is quantized pictorial data D1) line by line.This is read control section 1410 and this of one first row is quantized pictorial data D3 is kept in the buffer storage, up to the quantification pictorial data D3 of input next line (under this situation, being one second row).
Then, user is by holding this image reader 1300 and along this represented direction of arrow Z2 this image reader 1300 that slides, begin scanning on this document P.By this, this home roll 1304, the first additional rollers 1305, and the second additional roller 1306 is rotated because of a frictional force between they and this document P.In addition, this power transmission shaft 1303 of revolving force process of this home roll 1304, gear 1312, two-stage gear 1311 and gear 1310 are sent to this input shaft of this flexible blocking device 1309.By this, this moves test section 1308 and begins to detect of this image reader 1300 and move.At a shown moment t1 of Figure 20, when moving the mobile detection signal S3 of one of test section 1308 input from this, this reading control section 1410 identifies this image reader 1300 and has been moved the corresponding distance with delegation, and at shown this moment t6 of Figure 20, this reads this processing that control section 1410 is carried out the data transmission of interrupting this pictorial data direction correction part 1430.By this function, delegation is quantized pictorial data D3 and is corrected part 1430 from this pictorial data direction and outputed to this image data memory 1440 and this and be quantized pictorial data D3 and be stored in this image data memory 1440.
In this shown example of Figure 20, at moment t7, t8, the t9 actual figure reportedly send the processing of interruption, and with second row, fourth line and the 7th row are quantized pictorial data D3 accordingly and are sent to this image data memory 1440 respectively.By aforesaid operations, this each row that is quantized among the pictorial data D3 is kept in this image data memory 1440 continuously.Here, in this shown example of Figure 20, in a drive cycle T, import twice of a mobile detection signal S3 altogether at moment t2 and t3.When the translational speed of this image reader 1300 was higher than image reading speed of this image reader 1300, this situation just took place.Under this situation, this is read control section 1410 and carries out this shown data transmission Interrupt Process of Figure 20 according to a mobile detection signal S3 as a flop signal.
On the other hand, when the translational speed of this image reader 1300 is too low, perhaps when this image reader 1300 stops, in a drive cycle T, do not move detection signal S3 with regard to not importing this.Under above-mentioned this situation, only carry out with import previously and be stored in the processing that pictorial data D3 is updated to the quantized data of new input that is quantized in the buffer storage, and do not carry out the data transfer process of this image data memory 1440.When shown this image reader 1300 of Figure 41 is read the starting position when sliding on this document P one and reading end position from one, this user separates this image reader 1300 at a shown moment t5 of Figure 20 with this document P, finish this and read operation.So, stop partly to export this document detection signal S1 from this shown document detection of Figure 25.
As a result, this reading control section 1410 identifies to have finished reads operation, and finishes to the data transfer process of this image data memory 1440.Then, quantizing pictorial data D3 by this multirow of obtaining of first operation of reading an image is stored in this image data memory 1440 as the pictorial data of one first document P.When the manual direction (scanning direction) that this image reader 1300 edge arrow Z2 in this drawing are represented is upward mobile, this document P can be in any direction, the direction that for example makes progress, downward direction, be scanned on direction left and the direction to the right.So, use the image that this image reading part 1330 reads can be, and be decided by this scanning direction with any one different angle tilt or by mirror image.For example, when on this document P, a mirror image character " F " being arranged, any one image that this image of being read is the shown visual BG1 of Figure 47 in the BG8.Here, suppose and use this image reading part 1330 to read this shown source image of Figure 48 that this pictorial data direction is corrected part 1430 this visual BG5 and this source images that Figure 48 is shown and separated.Then, this pictorial data direction is corrected part 1430 by rotation 0 degree, and clockwise or anticlockwise revolving turn 90 degrees, and the further resulting image of mirror image, and this visual BG5 of being spaced shown from Figure 50 produces visual BG1 to BG8.
Below, this pictorial data direction is corrected part 1430 and is used the technology of explained later to identify visual BG1 character in each image in the visual BG8, and uses the highest identification certainty to select an image.Here, describe this technology be used to separate with identification character in detail.This technology is disclosed among " the TECHNICAL REPORT OF IEICE PRMU-25 (1997-93) " of Hisroshi Kamata and other electronic information communication society.In this technology, according to the sub-fraction feature of a character and then with a high-speed candidate characters that obtains from the big measure feature of this character as recognition result, this technology comprises a step of a character of separation and discerns a step of this character.
This character separates that to handle be that a image with a character quantizes a visual processing that separates with one that obtains from a text document.Processing separated in this character is the processing of a bottom, and one of them character is made up of a plurality of points, and carries out this processing according to following sequence.
At first, wherein the continuum that interconnects of the stain in each a zone essential characteristic being used as a character extracts.Then, obtain a common tangential rectangle of these a plurality of continuums, and decide the direction of this line, and extract a line that is used for the position extraction by analyzing this position relation.Further, continuum overlapped on a direction perpendicular to this line forms a group, and is comprehensive at a tangential rectangle that obtains this group perpendicular to the rectangle on the direction of this line.The tangential rectangle quilt of on the direction of this line these is comprehensive and be identified as a character, and a tangential rectangle of this uniform parts is identified as a tangential rectangle of a candidate characters.
Then, according to this tangential rectangle, on this line, interconnect a width and position that a candidate characters is judged in the position from these tangential rectangles as a candidate characters of a reference.Further, in this system, except this processing of separating a character, also carry out such processing, for example deletion is not the noise of a character, perhaps separates the character that is in contact with one another.
The processing of character recognition is to separate the processing that an image handling a character of separating is discerned a character by input with above-mentioned character, and carries out according to following selection sequence.
(1) normalization
In this was handled, in this character recognition was handled, an image of a character of separating with a virtual character frame was changed a normalization image of forming by 48 * 48.When this image counting or counting greater than 48 time on this horizontal direction on this vertical direction, this image is just compressed equably.But counting is count 3/4 o'clock of this normal image, just amplifies this image, so that its maximum edge is accommodated in this virtual character frame.
(2) feature extraction
In the processing of this feature extraction, from this normalization image extraction feature of a character.In this was handled, a profile that remains unchanged in the zone that obtains changed the feature that speed is identified as variable division direction so that profile is counted by dividing this character zone changeably.Promptly, after extracting some profile point, a tangential rectangle of a candidate characters is divided into wherein that each all has the subregion of the profile point of similar number, and obtains the direction character of this candidate characters on a long edge direction of this female tangential rectangle.At last, the characteristic of average portion rectangular area on a minor face edge direction of this female rectangle, and this average is as the last number of the feature of this candidate characters.
(3) compressed feature
In this is handled, the feature of a character that in above-mentioned characteristic extraction procedure, is extracted be compressed into comprise dimension less be compressed feature.The process that acquisition is compressed feature comprises that extracting one initially is compressed the characteristic coordinates axle and obtains to separate easily process of the less reference axis of the number of feature of a character and calculate the process that this is compressed feature by the feature that this initial coordinate axle system is converted on the Ka Dier coordinate axis system.
(4) big classification
In this process, obtain a candidate characters by using this that obtained in above-mentioned this characteristic extraction procedure to be compressed feature.In this big assorting process, use one simultaneously based on the high speed assorting process of guaranteeing precision and a process of coming macrotaxonomy based on distance calculation.In previous process, character feature based on exhaustive division is projected to a macrotaxonomy feature space, obtain wherein that each all has a plurality of characters of the possibility that is projected as a candidate characters table, search then with these a plurality of candidate characters in any one corresponding character.
But, in this process, substitute the projection that each is divided the zone, feature based on exhaustive division is directly projected to a macrotaxonomy feature space, and an edge is added in this projection distribution, by using character feature, make an identification catalogue bigger based on the exhaustive division of a character pattern.Only when as the number of the candidate characters of recognition result greater than 70 the time, just use this back process.
(5) identify in detail
In this process, these candidate characters that obtain are carried out the calculating of the distance between the candidate characters in input characters and this identification catalogue in above-mentioned this macrotaxonomy process.And carry out a distance ordering, a candidate characters that has minimum range then is identified as a last candidate characters of this input character.
Turn back to Figure 50, this pictorial data direction correct part 1430 (with reference to Figure 45) check the shown visual BG1 of Figure 50 in visual BG8, have this anglec of rotation or its mirror image of an image of the highest identification certainty or the highest accurate identification possibility.In Figure 50, having deterministic this image of the highest identification is visual BG1 (identification certainty=0.97).This pictorial data direction is corrected part 1430 in order to correct this and to be rotated or by a direction of mirror image (with reference to Figure 47), obtain this and be repaired pictorial data on the direction, carry out and the conversion identical conversion of the picture inversion that is spaced by a result, obtain the data of an image of (with reference to Figure 48) in the right direction for an image in the right direction concerning be quantized this source image that pictorial data D3 obtained from this according to this detection.
Below, this pictorial data direction is corrected part 1430 and will be repaired pictorial data as this of a pictorial data that is repaired and output to this image data memory 1440.Further, when this pictorial data direction is corrected part 1430 when a direction of the image of this acquisition is corrected as a correct direction, inclination (attitude) from this image reader 1300 that testing result obtained of this correcting inclination part 1340 (skew detection signal S7) is responded, and this pictorial data direction is corrected a correct direction of an image of part 1430 checks.

In this shown data processing section 2151 of Figure 85, after a document detection signal S1 and mobile detection signal S3 are as a flop signal input, read control section 2152 with a specified period for one, read a drive signal S2 of the delegation of an image on the document (not showing) to these image reading part 107 outputs.In addition, this is read control section 2152 and also provides an instruction that determines to read condition to this reading conditional decision part 2153.Here, the condition of this reading is to be used as monochrome image data (quantized data) employed quantization threshold when reading when an image on the document in this image reading part 107.
After input is as an instruction flop signal, from this reading control section 2152, this is read conditional decision part 2153 and determines the reading condition (quantization threshold) an of the best to obtain to compare with the row image data that this image reading part 107 is read, and does not have an image of deepening or distortion.This reads conditional decision part 2153 these reading conditions (quantization threshold) of decision, and with this condition setting in this image reading part 107.Here, this is read conditional decision part 2153 and uses with above-mentioned and decide a reading condition with reference to the identical method of the described method that determines a quantization threshold of Figure 46.Understand the details of this determining method with reference to Figure 46.This image reading part 107 is read this reading condition (quantization threshold) that conditional decision part 2153 is determined according to this, corrects and change an image on this reading documents.
(first example of the operation of execution mode 17)
Below with reference to the flow graph of Figure 86 a example according to the operation of this image reader 2150 of execution mode 17 is described.Suppose that the reading of an image is affected after a mains switch that does not have to show is opened, and shown this image reader 2150 (document detection part 105) of supposition Figure 85 is not near a document.Then, in the shown step SN1 of Figure 86, this read control section 2152 by make a lamp and brighten or similarly mode can read image to this user report, this system's control forwards step SN2 to then.
In step SN2, this is read control section 2152 and enables the input from a document detection signal S1 of this document detection part 105 is received, and this system's control forwards step SN3 to then.Here, this document detection signal S1 is when this image reading surface of document contact (contact tightly) when (not showing), from a signal of these document detection part 105 outputs.In step SN3, this is read control section 2152 and judges whether this document detection part 105 detects this document, in other words, whether has imported a document detection signal S1 from this document detection part 105.Because this image reader 2150 (document detection part 105) not near a document, is a "No" so this reading control section 2152 identifies a judged result, and this system's control turns back to step SN2.Then, when a user is placed on this image reader 2150 on the document, so that its this document of image reading surface contact, because this document detection part 105 tightly contacts mutually with this document, so read document detection signal S1 of control section 2152 outputs to this from this document detection part 105.
By this, the judged result that this reading control section 2152 identifies among the step SN3 is a "Yes", and this system's control forwards step SN4 to.In step SN4, this reading control section 2152 enables the input of a mobile detection signal S3 who moves test section 401 from this is received, and this system's control forwards step SN5 to then.Here, this moves detection signal S3 and moves, moves a signal of test section 401 outputs from this according to this of reading control section 2152.In step SN5, this is read control section 2152 and judges that this that move by this that moves test section 401 inputs from this that detection signal S3 obtained moves whether greater than this threshold value.When this judged result was "No", this system's control turned back to step SN4, and this reads control section 2152 repetition aforesaid operations sequences.Here, this judged result among the step SN5 be this situation of "No" represent this image reader 2150 because of the influence of vibration a slight situation that moves.That is, provide step SN5 to prevent a misoperation that causes because of the influence of vibration.
Then, this user is by the operation identical operations of execution with an image of above-mentioned reading, catch under the situation of this document of this image reader 2150 and its image reading surface contact this user this image reader 2150 that on this scanning direction, slides this user.By this operation, output is according to one of this image reader 2150 a mobile mobile detection signal S3, and when this is moved beyond this threshold value, the judged result that this reading control section 2152 identifies among the step SN5 is a "Yes", and this system's control forwards step SN6 to.In step SN6, this is read control section 2152 and provides an instruction that determines a reading condition (for example, quantization threshold) to this reading conditional decision part 2153.
By this operation, this reads the reading condition (quantization threshold) that determines a best the row image data of conditional decision part 2153 from the document that this image reading part 107 is read, and with this condition setting in this image reading part 107.In step SN7, each next drive signal S2 at interval when this is read control section 2152 and is input to this image reading part 107, just reads an image according to this reading condition (quantization threshold) at each official hour.
(second example of the operation of execution mode 17)
In above-mentioned first operation example, describe and to have supposed by under the situation that is moved beyond according to this of this image reader 2150 as this threshold value of a condition (with reference to the step SN5 among Figure 85), determine a condition of reading, prevent a situation of the misoperation of generation because vibrate.But, in first operation example, by because repeatedly vibrate the accumulation of the minute movement that produces, total this threshold value that is moved beyond.So, under the situation of a reality, may produce a misoperation, although wherein this image reader 2150 does not move, it is judged as this image reader 2150 and is moving.How second example that the back is described this operation in detail prevents above-mentioned misoperation.
In Figure 87, step SO1 to step SO3 and step SO9 and step SO10 respectively with Figure 86 in shown step SN1 corresponding to step SN3 and step SN6 and step SN7.That is, in second operation example, step SO4 substitutes the shown step SN4 of Figure 86 and the sequence of operation of step SN5 to the sequence of operation of step SO8.
Promptly, in the shown step SO1 of Figure 87, by lighting lamp or similar, report a state that can carry out image reading, and in step SO2, receive a document detection signal S1, in step SO3, this is read control section 2152 and judges whether this document detection part 105 detects a document then.When this image reader 2150 is placed on this document by this user, by carrying out and the aforesaid operations identical operations, this document detection signal S1 just outputs to this from this document detection part 105 and reads control section 2152, by this, the judged result that this reading control section 2152 identifies among the step SO3 is a "Yes", and this system's control forwards step SO4 to.
In step SO4, this is read 2152 moving parameter k of control section and is set to " 0 ", and this system's control forwards step SO5 to.Here, this moving parameter k is a mobile parameter of this image reader 2150 of expression.In step SO5, this is read control section 2152 judgements and whether carries out next the interruption in 5 milliseconds that have no progeny one since this flexible blocking device 402 (with reference to Figure 10) that moves test section 401 from this receives.In other words, this is read control section 2152 and judges in receiving these after moving detection signal S3 5 milliseconds whether imported next mobile detection signal S3.This moves detection signal S3 is that this reads a pulse signal of being exported when control section 2152 is moved a predetermined distance each time.
When this judged result among the step SO5 was "No", the control of this system turned back to step SO4, and this reads control section 2152 this moving parameter k and be set to " 0 ", and this system's control forwards step SO5 to.Here, when a situation that moves a slight distance because this reads once vibrating of control section 2152, when a mobile detection signal S3 is output, this judged result that this reading control section 2152 identifies among the step SO5 is a "Yes", and this system's control forwards step SO6 to.In step SO6, this reading control section 2152 increases 1 with this moving parameter k, and (under this situation, k=1), this system's control forwards step SO7 to then.In step SO7, this is read control section 2152 and judges whether this moving parameter k (=1) is 4, and in other words, this moves whether surpass this threshold value.Under this situation, because this moving parameter k is 1, so this judged result that this reading control section 2152 identifies among the step SO7 is a "No", and this system's control forwards step SO8 to.
In step SO8, this is read control section 2152 and waits for 5 milliseconds, and this system's control turns back to step SO5 then.Here, when as above-mentioned, when not importing next mobile detection signal S3 in 5 milliseconds, this is read control section 2152 and turns back to step SO4, and this is read control section 2152 this moving parameter k and is set to " 0 ", and this system's control forwards step SO5 to.That is, under this situation,, caused this of the vibration that produces previously be reset, so can avoid inconvenience in above-mentioned first operation example, that produce because of the accumulation of moving each time that vibration causes because moving.
This user is by the operation identical operations of execution with an image of above-mentioned reading, catch under the situation of this document of this image reader 2150 and its image reading surface contact this user this image reader 2150 that on this scanning direction, slides this user.By this operation, output is according to one of this image reader 2150 a mobile mobile detection signal S3 continuously.Under this situation, because in step SO8, in 5 milliseconds, imported this and moved detection signal S3, so repeating step SO5 is to this circulation of step SO7.When this moving parameter k reaches " 4 " (this is moved beyond this threshold value), this this judged result of reading that control section 2152 identifies among the step SO7 is a "Yes", and this system's control forwards step SO9 to.In step SO9, as above-mentioned, this is read control section 2152 and provides an instruction that determines a reading condition (for example, quantization threshold) to this reading conditional decision part 2153.
By this operation, this reads the reading condition (quantization threshold) that determines a best the row image data of conditional decision part 2153 from the document that this image reading part 107 is read, and with this condition setting in this image reading part 107.In step SO10, each next drive signal S2 at interval when this is read control section 2152 and is input to this image reading part 107, just reads an image according to this reading condition (quantization threshold) at each official hour.
Supposed a quantization threshold as a situation of reading condition according in this image reader 2150 of execution mode 17 although this is described, the reading condition is not limited to said circumstances, and can adopt any other condition.The method of a condition that further, described in the execution mode 17, an image of decision reading can be used for any one of above-mentioned execution mode 1 to 16.In addition, this above-mentioned determining method can also be used for image reader 1 of an operation keys 3 shown just like Figure 110.Under this situation, in the shown step SN1 of Figure 86, this user presses this operating parts 3.By this operation, execution in step SN2 is to the sequence of operation of step SN7.
As above-mentioned, by using this image reader 2150 according to execution mode 17, this document detection part 105 moves test section 401 with this and detects situation and the illustrated reading operation of this user that this visual movable part 107 contacts this document, determine a reading condition (quantization threshold) then so that can avoid being similar in the conventional art, based on blank being identified as one of document surfaces judgement of reading condition.That is, always decide a reading condition according to pictorial data as a document of a reading object.So,, carry out image reading according to an optimal read condition relevant, so can obtain a high-quality image at any time with this document by using this image reader 2150 according to execution mode 17.
In addition, by using this image reader 2150 (first operation example) according to execution mode 17, just determine a reading condition when being moved beyond a threshold value for one, so that can avoid when because the influence of vibration, this installs slight when mobile and a misoperation that produces.
Further, by using this image reader 2150 (second operation example) according to execution mode 17, at the shown step SO4 of Figure 87 in step SO8, when one in 5 milliseconds move do not reach one pre-set apart from the time, k is set to " 0 " by this moving parameter, with regard to this accumulation of moving that has resetted and produced because of vibration.As above-mentioned, in second operation example, can avoid the misoperation that produces, so further improved the reliability and the adaptability of this device because vibrate the accumulation of moving each time that causes.
According to Figure 88, Figure 89 and Figure 90 describe an image reader 2200 according to embodiment of the present invention 18.Figure 88 is the block diagram of demonstration according to the structure of this image reader 2200 of execution mode 18, and Figure 89 is a block diagram reading the structure of operation part 2210 that shows that Figure 88 is shown.Figure 90 is a block diagram of the structure of a shown visual retaining part 2230 of demonstration Figure 88.In Figure 88 and Figure 89, identical label be assigned to Figure 13 in corresponding those parts of parts.Outward appearance and structure according to this shown image reader 500 of these image reader 2200 outward appearances of execution mode 18 and structure and Figure 10 that the back will be described are identical.
Here, the purpose according to this image reader 2200 of execution mode 18 that the back will be described in detail is the problem that is used for solving the traditional type image reader of describing to Figure 116 with reference to Figure 114, is not good problem because can not carry out the processing adaptability of reading and causing continuously promptly.
In Figure 88, this image reader 2200 comprises an image reading part 107, and this is read 2210, one of operation parts and reads control section 2220, this 2230, one data processing sections 2240 of visual retaining part and a data retaining part 2250.This image reading part 107 is read image on the document (not show) and output this image as pictorial data optically.This is read operation part 2210 and begins to read of a image on the document and read commencing signal and be used for order and finish to read an of image and read end signal and output to this and read control section 2220 by being used for order, comes the reading of the pictorial data of this image reading part 107 of order.
As shown in Figure 89, this is read operation part 2210 and comprises reading operation mark 2211, one document detection parts 105 of part (with reference to Figure 13), a mobile test section 401 (with reference to Figure 13).When from this document detection part document detection signal S1 of 105 inputs with when this moves the mobile detection signal S3 of one of test section 401 input, this is read operation mark part 2211 and judges that this image reader 2200 is placed on the document and quilt slides along this document, promptly carried out and read operation, and read one of control section 2220 (with reference to Figure 88) output to this and read commencing signal.When stopping from document detection signal S1 of this document detection part 105 inputs, this is read operation mark part 2211 and judges that having finished this reads operation, and reads one of control section 2220 (with reference to Figure 88) output to this and read end signal.
Turn back to Figure 88, read operation part 2210 inputs when this and read as an of flop signal after commencing signal and one reads end signal, this is read one of control section 2220 control and reads operation.The details that this reads the operation of control section 2220 will be described with reference to a flow graph in the back.This visual retaining part 2230 is to be used for an interim memory that keeps this pictorial data of being read by this image reading part 107.This reads control section 2220 controls to the writing of the pictorial data of this visual retaining part 2230, and the reading of this data processing section 2240 these pictorial data of being write of control.That is, in this visual retaining part 2230, the reading of carrying out simultaneously respectively under these reading control section 2220 controls that writing under control and 2240 controls of this data processing section is controlled.So, in this visual retaining part 2230, carry out simultaneously and read and write.
Here, describe the structure of this shown visual retaining part 2230 of Figure 88 in detail with reference to Figure 90.In this drawing, a buffer storage group 2231 comprises number from 2231 1To 2231 MM buffer storage, and be written to wherein from the pictorial data of this image reading part 107.In this M buffer storage 2231 1To 2231 MIn, subscript 1 to M is the buffer storage number of each memory of sign.
Then in buffer storage 2231 1To 2231 MIn, when pictorial data will be written into, this writes selector 2233 can select in the buffer storage any one, and pictorial data is written in this selecteed buffer storage.Under this situation, be chosen in an empty buffer memory that wherein is not saved pictorial data.Read under the control of control section 2220 (with reference to Figure 88) at this, one writes writing of pictorial data in the control section 2232 control buffer storage 2231.
In more detail, when this reading control section 2220 (with reference to Figure 88) sends instruction that begins to preserve, when promptly importing a write signal, this writes control section 2232 controls, and this writes selector 2233, so that select an empty buffer memory with reference to a buffer storage supervisory table 2236 from buffering memory 2231.
Here, this buffer storage supervisory table 2236 is expression buffer storage 2231 1To buffer storage 2231 M Buffer storage number 1 to M and expression respectively in buffer storage 2231 1To buffer storage 2231 MIn have or do not have pictorial data one the sign between a dependency relation.When this was masked as " 1 ", its presentation image data was written in the corresponding buffer storage.In the shown example of this figure, pictorial data is written into the buffer storage 2231 of buffer storage number " 1 " 1In.
On the other hand, when this was masked as " 0 ", its presentation image data was not written in the corresponding buffer storage, and promptly this corresponding buffer storage is empty.In the shown example of this figure, pictorial data is not written into the buffer storage number and is respectively the buffer storage 2231 that " 2 " arrive " M " 2To buffer storage 2231 MIn.As the result of conduct with reference to this buffer storage supervisory table 2236, when all were masked as " 1 ", this write control section 2232 and is illustrated in buffer storage 2231 to this reading control section 2220 (with reference to Figure 88) output 1To buffer storage 2231 MThe full signal of a buffering that is not free buffer storage is so that pictorial data can not be written to wherein.
In more detail, when sending instruction that begins to read from this data processing section 2240 (with reference to Figure 88), promptly when read signal of input, this reads control section 2234 controls, and this reads selector 2235, so that select a buffer storage that wherein writes pictorial data with reference to this buffer storage supervisory table 2236 from buffering memory 2231.As the result of conduct with reference to this buffer storage supervisory table 2236, when all were masked as " 0 ", this read control section 2234 to these data processing section 2240 output expression buffer storage 2231 1To buffer storage 2231 MComplete empty, promptly all pictorial data are by from buffering memory 2231 1To buffer storage 2231 MA buffering spacing wave that reads.
Turn back to Figure 88, read control by this visual retaining part 2230 is carried out, 2240 pairs of pictorial data that are read of this data processing section are carried out data processing, for example correct its inclination or carry out data compression.This data holding section 2250 keeps being undertaken by this data processing section 2240 pictorial data of data processing therein.

In step 8R8, this writes control section 2232 and judges whether this parameter i (=2) that selects a write buffering memory selects beginning buffer storage constant m (=1) to equate with this.That is, in step SR8, judge whether all buffer storage in the buffer storage group 2231 to have been carried out the check that pictorial data occurs or do not have to occur.Under this situation, this judged result that writes that control section 2232 identifies among the step SR8 is a "No", and this system's control turns back to step SR4.
In step SR4, this writes control section 2232 by carrying out and the aforesaid operations identical operations, with reference to this buffer storage supervisory table 2236, judges whether pictorial data is written to this second buffer storage 2231 2In.Under this situation, this judged result that writes that control section 2232 identifies among the step SR4 is a "No", and this system's control forwards step SR10 to.In step SR10, this writes control section 2232 and selects this second buffer storage 2231 2, and this system's control turns back to step SR11 then.
In step SR11, this writes control section 2232 and writes selector 2233 by controlling this, begin to control Figure 95 shown, will be used as and write the pictorial data that data are preserved (" buffering area 2 ") from this image reading part 107, and this system's control forwards step SR12 to then.By this operation, be kept at this second buffer storage 2231 continuously line by line by this second pictorial data that operation obtained of reading an image 2In.In step SR12, this writes control section 2232 and judges whether that reading control section 2220 from this has imported an instruction that finishes preservation, and because under this situation, this second reading operation is still being carried out, so a judged result that identifies among the step SR12 is that "No" and the control of this system turn back to step SR11, repeats the aforesaid operations sequence.
Then, when having finished this second reading operation, this user separates this image reader 2200 and this document.By this operation, just stop to export this document detection signal S1 from this document detection part 105 (with reference to Figure 89), so the judged result that this reading operation mark part 2211 identifies among the shown step SP4 of Figure 91 is a "No", and this system's control forwards step SP5 to.In step SP5, this is read operation mark part 2211 and reads one of control section 2220 output to this and read end signal, and this system's control turns back to step SP1, and repeats the aforesaid operations sequence.Under this situation, because do not begin this 3rd reading operation, so this judged result of reading that operation mark part 2211 identifies among the step SP1 is a "No", and this system's control turns back to step SR11, and repeats this identical judgement.
Then, when reading this reading end signal of operation mark part 2211 inputs from this, the judged result that this reading control section 2220 identifies among the shown step SQ5 of Figure 92 is a "Yes", and this system's control forwards step SQ6 to.In step SQ6, this reads control section 2220 by stopping to export a write signal, writes control section 2232 (with reference to Figure 90) to this of this visual retaining part 2230 and sends and be used to finish the instruction that pictorial data is preserved.By this operation, this judged result that writes that control section 2232 identifies among the step SR12 is a "No", and this system's control forwards step SR13 to, this writes control section 2232 and be set to " 1 " with corresponding this sign of this second buffer storage in this buffer storage supervisory table 2236, and this system's control turns back to step SR2, and repeats the aforesaid operations sequence.That is, under this situation, " 1 " be separately positioned in this buffer storage supervisory table 2236 with the corresponding sign of this first and second buffer storage in.
After this step, when reading from this first buffer storage 2231 1The centre of data (with reference to Figure 95), when beginning to read one the 3rd operation of an image, by aforesaid operations, at the shown moment t3 of Figure 95, a write signal is imported into this and writes in the control section 2232.By this operation, this writes control section 2232 and select one the 3rd buffer storage 2231 in step SR10 (with reference to Figure 93) 3, and shown this of Figure 95 writes data (buffering area 3) and is written to this 3rd buffer storage 2231 3In.Then, " 1 " is set in this shown buffer storage supervisory table 2236 of Figure 90 and this 3rd buffer storage 2231 3In corresponding this sign, and to select this parameter i of a write buffering memory be 3.
Then, when beginning immediately to read one the 4th operation of an image after having finished this 3rd image reading operation, by aforesaid operations, a write signal is imported into this and writes in the control section 2232.But, because as shown in Figure 95, this by read data by from this first buffer storage 2231 1The centre of reading is not so be free buffer storage in this buffer storage group 2231.So, under this situation, can not be written in this buffer storage group 2231 preserving data.
In the shown step SR2 of Figure 93, this writes control section 2232, and to identify a judged result be that the control of "Yes" and this system forwards step SR3 to, this parameter i (=3) of a write buffering memory is selected in substitution in a selection-beginning buffer storage constant m, and this system's control forwards step SR4 to then.In step SR4, this writes control section 2232 by judging with reference to this buffer storage supervisory table 2236 whether pictorial data is written to this 3rd buffer storage 2231 3In.Under this situation, because pictorial data is written to this 3rd buffer storage 2231 3In, to identify a judged result be that the control of "Yes" and this system forwards step SR5 to so this writes control section 2232.
In step SR5, this writes control section 2232 and will select this parameter i of a write buffering memory to increase by 1 (=3), and this system's control forwards step SR6 to then.Under this situation, selecting this parameter i of a write buffering memory is 4.In step SR6, this writes control section 2232 and judges that this parameter i (=4) that selects a write buffering memory is whether greater than the total number M (=3) of buffer storage.Under this situation, this writes control section 2232, and to identify a judged result be "Yes", and this system's control forwards step SR7 to.
In step SR7, this writes control section 2232 substitution " 1 " in this parameter i that selects a write buffering memory, and this system's control turns back to step SR8.In step SR8, this writes control section 2232 and judges whether this parameter i (=1) that selects a write buffering memory selects beginning buffer storage constant m (=3) to equate with this, and this judged result that writes that control section 2232 identifies among the step SR8 is a "No" under this situation, and this system's control turns back to step SR4.After this step, the sequence of steps of repeating step SR4 in the step SR8, and with this first buffer storage 2231 1To this second buffer storage 2231 2Or the like order check pictorial data whether to be stored in the buffer storage.
Then, in step SR8, when this parameter i (=3) that selects a write buffering memory selects beginning buffer storage constant m (=3) when equating with this, this writes control section 2232, and to identify a judged result be "Yes", and this system's control forwards step SR9 to, read control section 2220 output buffer full signals (with reference to Figure 95) to this, and this system's control turns back to step SR2 then.That is,, do not have empty store in the buffer storage 2231, just do not carry out this 4th operation of reading an image because under this situation.
When having finished from this first buffer storage 2231 1During read data (with reference to Figure 95), this data processing section 2240 is read control section 2234 output read signal (with reference to Figure 95) to this.By this operation, the judged result that this reading control section 2234 identifies among the step SS2 is a "Yes", and this system's control forwards step SS3 to.In step SS3, this is read control section 2234 substitution in this selection-beginning buffer storage constant n and selects a parameter j (1, under this situation) who reads buffer storage, and this system's control forwards step SS4 to then.
In step SS4, this reads control section 2234 by judging with reference to this buffer storage supervisory table 2236 whether pictorial data is written to number and the identical j buffer storage 2231 of this parameter j of selecting one to read buffer storage 1In.Under this situation, because pictorial data is not written to this first buffer storage 2231 1In, be "No" so this reading control section 2234 identifies a judged result, and this system's control forward step SS5 to.
In step SS5, this is read control section 2234 and will select this parameter j (=1) that reads buffer storage to increase by 1, and this system's control forwards step SS6 to then.Under this situation, selecting this parameter j that reads buffer storage is 2.In step SS6, whether this reads control section 2234 and judges and select this parameter j (=2) that reads buffer storage greater than the total number M (=3) of buffer storage.Under this situation, it is "No" that this reading control section 2234 identifies a judged result, and this system's control forwards step SS8 to.If a judged result among the step SS6 is a "Yes", this system's control forwards step SS7 to, and this reads control section 2234 substitution " 1 " in this parameter j that selects a reading buffer storage, and this system's control forwards step SS8 to then.
In step SS8, this is read control section 2234 and judges to select this parameter j (=2) that reads buffer storage whether to equate with this selection-beginning buffer storage constant n (=1), and under this situation, identifying a judged result is "No", and this system's control turns back to step SS4.If a judged result among the step SS8 is a "Yes", this reads control section 2234 by the signal to a buffer empty of these data processing section 2240 outputs, this is read control section 2234 and is reported in to this data processing section 2240 and does not have the pictorial data that will be read in the buffer storage 2231, and this system's control turns back to step SS2, and repeats the aforesaid operations sequence.
In step SS4, this reads control section 2234 by reference buffer memory 2236, judges whether pictorial data is stored in number and this identical second buffer storage 2231 of this parameter j (=2) of selecting one to read buffer storage 2In, and under this situation, identifying a judged result is "No", and this system's control forwards step SS10 to.By this operation, after step SS10, by with the aforesaid operations identical operations, pictorial data as by read data (buffering area 2 among Figure 95) from this second buffer storage 2231 2In be read out.
When having finished from this first buffer storage 2231 1After the middle read data (buffering area 1 among Figure 95), when carrying out one the 4th operation of reading an image, at the shown moment t4 of Figure 95, a write signal is imported into this and writes control section 2232 (with reference to Figure 90), so the judged result that this visual retaining part 2230 identifies among the step SR2 is a "Yes", and the sequence of operation among the execution in step SR3 etc.In this moment point, because this first buffer storage 2231 1Be empty,,, write data (buffering area 1 among Figure 95) and be stored in this first buffer storage 2231 by aforesaid operations so write under the control of control section 2232 at this 1In.
As above-mentioned,, a plurality of buffer storage 2231 are wherein provided by using this image reader 2200 according to execution mode 18 1To 2231 MCarry out this independently and write control section 2232 and this and read control section 2234 performed readings and handle and write processing, so during shown this of Figure 95 read processing execution, can carry out this and write processing.So, by using this image reader 2200, can carry out continuously and read operation according to execution mode 18, this has improved the adaptability that the user handles greatly.
