Fig. 7 is the figure of read direction of the detected value of the linear imaging sensor 111A that possessed of explanation first scanner 111 and second scanner 112,112A.Wherein, because the linear imaging sensor 111A that possessed of first scanner 111 is identical with the linear imaging sensor 112A that second scanner 112 is possessed, therefore in the formation of the 111A of linear imaging sensor shown in Fig. 7.
As shown in Figure 7, linear imaging sensor 111A possesses a plurality of photo detector 110A that become row to arrange with linearity along extending with the direction of the direction of transfer quadrature of recording medium S.Linear imaging sensor 111A forms 1 row or multiple row, and its quantity is not special to be limited.Linear imaging sensor 111A specifically is a cmos image sensor, and photo detector 110A for example is each unit of CMOS.In the example of Fig. 7, alignment arrangements 256 photo detectors, with an end of 0 side on the main scanning direction as the position reset, with an end of opposition side as position " 255 ".
First scanner 111 is seen the mode of detected value (electric charge) of a plurality of photo detector 110A of linear imaging sensor 111A in order successively off and is exported according to the photo detector 110A since an end.In proper order no matter the output of the detected value of photo detector 110A from which end at linear imaging sensor 111A two ends begin earlier and can carry out; For example as shown in Figure 7; Left side (0 side) that also can be when the clockwise direction represented with symbol A transmits recording medium S is as the front, from position 0 to the position till 255 to gate array 45 output detected values.This output is that the specification according to the connection state of first scanner 111 and gate array 45 etc. or first scanner 111 decides in proper order.
The detected value of linear imaging sensor 111A output (electric charge or with the corresponding magnitude of voltage of electric charge) is imported in the gate array 45.Specifically be, gate array 45 constitutes FPGA (Field Programmable Gate Array), and the electric charge from each pixel of linear imaging sensor 111A input is quantized, and generates the data of each pixel then and is kept among the built-in data maintaining part 45A.
Gate array 45 generates the data of each pixel according to the detected value from each photo detector of first scanner, 111 inputs, and is kept among the data maintaining part 45A according to the data of genesis sequence with each pixel that is generated.And the data that gate array 45 will be kept among the data maintaining part 45A are exported according to this preservation order or reverse order.The order of the data among the gate array 45 dateout maintaining part 45A can be switched setting through the control of CPU40.That is to say; Gate array 45 is according to the control of CPU40, can switch output with linear imaging sensor 111A in the identical direction that puts in order of each photo detector disposed after each pixel data data and with opposite arranged in order the data of each pixel data.
Then, be divided into situation and the reverse situation that transmits recording medium that forward transmits recording medium S, the action of reading of click type printer 10 is described.
Fig. 8 be expression click type printer 10 read in the action, especially forward reads the figure of action.Fig. 8 (A) representes the scanning direction, and Fig. 8 (B) is the figure that schematically shows the action that integral body reads, and Fig. 8 (C) is the figure that schematically shows the action of reading the appointed area.
Under click type printer 10 situation that (the symbol A among Fig. 3) reads in a clockwise direction; From the front side (left side of Fig. 3) of click type printer 10 rearward side (right side of Fig. 3) transmit recording medium S during in; Recording medium S is read by first scanner 111 and 112 couples of recording medium S of second scanner through optical pickup device 110.
At this moment, shown in Fig. 8 (A), from the front end of read range R (upper end the figure) to the back-end (lower end among the figure) read.Have, the reading images of correspondence that first scanner 111 and second scanner 112 are read, 1 row is with from the left end (root of arrow) of the read range R order to right-hand member (front end of arrow) again, according to by gate array 45 output of whenever passing through.Therefore, the left end of the front end of read range R becomes and reads the starting position, and the right-hand member of rear end becomes end position.
CPU40 is according to the instruction of sending from master computer 200, carrying out shown in Fig. 8 (B), cutting apart read range R along the scanning direction by each specific length under the situation that integral body reads, and at this, the each several part after will cutting apart is called piece.The read range R of the read range R of first scanner 111 and second scanner 112 is split into a plurality of respectively by specific length, begin to give numbering to each piece in order from the front of scanning direction.Specifically be, begin to give in order numbering from the front of the read range S of upper surface and lower surface, the piece 1 above promptly, following piece 2, below give along the scanning direction number block 3,4 ..., 8.The length of the piece of rear end is that the length of read range R is divided by remaining length after the specific length.
Each piece becomes the processing unit that the reading images of first scanner 111 and second scanner 112 is sent to master computer 200.That is to say that CPU40 has stored under corresponding 1 the situation of reads image data in the frame buffer of RAM41 (omitting diagram), the reads image data of 1 of this correspondence is sent to master computer 200.Afore mentioned rules length, be that the length of the piece of direction of transfer (scanning direction) is to decide according to the capacity that is arranged on the frame buffer (omitting diagram) among the RAM41.For example, have at frame buffer under the situation of capacity of reads image data of the full color that can store corresponding 300 row ultimate resolutions (600dpi), the length of piece is set to the suitable length below 300 row.
When execution integral body reads; CPU40 control motor driver 46 also makes medium transmit motor 26 rotations; Transmit recording medium S with fixing speed, control gate array 45 simultaneously makes the light source luminescent of first scanner 111 and second scanner 112; And the detected value based on linear imaging sensor 111A, 112A generates reads image data, reads image data is stored into line by line on the frame buffer of RAM41.
Till reading by first scanner 111 and 112 couples of whole read range R of second scanner; CPU40 continues above-mentioned action under the situation of the not transmission of interruption logging medium S; Any one piece reads end in this action; And in the frame buffer stored of RAM41 under corresponding 1 the situation of reads image data; Send to master computer 200 after from frame buffer, reading this reads image data of corresponding 1, the reads image data that finishes is sent in deletion from frame buffer.Through the deletion reads image data, thereby produce bigger clear area, the reads image data after can storing in the frame buffer once more.
Whenever the end of reading of 1 piece, CPU40 is just such as stated to send reads image data to master computer 200.The order of sending the reads image data of each piece is to read the order of end, is not limited to the number order of piece.
Have, CPU40 is under the situation of carrying out reading the appointed area according to the instruction that receives from master computer 200 again, and shown in Fig. 8 (C), configuration is by the zone of the reading object of setting command appointment in read range R.In the example of Fig. 8 (C), configuring area A1, A2 among the superincumbent read range R, configuring area A3 among the read range R below.
CPU40 comes configuration block according to the zone of the reading object that is disposed.At this, CPU40 under the short situation of the length of the length on the scanning direction in the zone that is disposed than above-mentioned, with a zone as a piece.The front-end and back-end of this piece are consistent with the front-end and back-end in zone.Under the situation of length than above-mentioned specific length length in zone, CPU40 begins to cut apart by specific length the zone of reading object from the front side of scanning direction.In the example of Fig. 8 (C),,, regional A3 is divided into piece 2,4 so regional A1 is divided into piece 1,3 because regional A1, A3 have surpassed specific length.The numbering of piece is identical when reading with integral body, gives according to the order of the position of the front end of piece.At this, the adding method of block number also can be: be divided into top and bottom, give numbering to each top piece by the order of the position of front end, then give numbering to each following piece by the order of the position of front end.Have again, also can be regardless of top and bottom, give numbering by the order of the position of the front end of each piece, can also alternately give numbering to the piece of top and bottom.
In addition, on the Width of read range R and under situation overlapping on the scanning direction, the All Ranges that these are overlapping is as a chunk in a plurality of area arrangement of reading object.Surpass in the length of the scanning direction of this chunk under the situation of the upper limit of block length, on the scanning direction, be divided into a plurality of.
Afterwards, CPU40 begins the reading of regional A1-A3 of read range R.CPU40 reads the transmission interruption that all zones can not make recording medium S before at first scanner 111 and second scanner; Control gate array 45 and motor driver 46 continue to read action; Above in this action or below reading of any one piece finish and in the frame buffer of RAM41, stored under corresponding 1 the situation of reads image data; From frame buffer, read the reads image data of 1 of this correspondence and send to master computer 200, the reads image data that finishes is sent in deletion from frame buffer.The sending order of this moment is identical when reading with integral body, is the order that reads the piece of end, is not limited to the number order of piece.
Master computer 200 receives the reads image data of sending from click type printer 10, by each piece and based on information such as titles, and the reconstruct reads image data.And then master computer 200 is being specified under the whole situation about reading according to the setting command that sends to click type printer 10, generates the reads image data of whole read range R to top and following combined block respectively.Have again; Master computer 200 is under the situation of having specified the appointed area to read according to setting command; When 1 zone is split into a plurality of, combine these pieces, directly use the reads image data of this piece when constituting 1 piece, thereby generate each regional reads image data in 1 zone.
Fig. 9 is the especially reverse figure that reads action in the action that reads of expression click type printer 10.Fig. 9 (A) representes the scanning direction, and Fig. 9 (B) is the figure that schematically shows the action that integral body reads, and Fig. 9 (C) is the figure that schematically shows the action of reading the appointed area.
Carry out under the situation of reverse read at click type printer 10; From the rear side of click type printer 10 forwards side transmit recording medium S during in; Recording medium S is read by first scanner 111 and 112 couples of recording medium S of second scanner through optical pickup device 110.At this moment, shown in Fig. 9 (A), read from rear end (lower end the figure) forward end of read range R (upper end among the figure).The reading images of 1 row that first scanner 111 and second scanner 112 are read is that the left end from read range R begins to be exported via gate array 45 in order; Therefore the left end of the rear end of read range R becomes and reads the starting position, and the right-hand member of front end becomes end position.
Being reversed under the situation that integral body reads, shown in Fig. 9 (B), begin read range R is divided into piece from the rear end.The numbering of this piece is that a side that becomes the front when reading begins to be endowed order.Other action is all read identical with clockwise integral body.
Have again, be reversed under the situation about reading the appointed area, shown in Fig. 9 (C), according to the zone of the setting command configuration reading object that receives from master computer 200, then from the front of scanning direction, be that the rear end side of read range R begins configuration block.Have again, as benchmark, cut apart zone above the upper limit of block length by specific length with the rear end side of read range R.Other actions are all read identical with clockwise appointed area.
Reverse read to reads image data and clockwise reads image data be up and down opposite.Therefore; The CPU40 of click type printer 10 also can make the reads image data upset send to the processing of master computer 200 afterwards; But the master computer 200 that has sent setting command has the information relevant with the scanning direction; Therefore based on this information, master computer 200 also can make the processing that spins upside down of reads image data.
Figure 10 schematically shows the figure of click type printer 10 to the data structure of the reads image data of master computer 200 transmissions.
The CPU40 of click type printer 10 will form the packet shown in Figure 10 (B) by the reads image data that first scanner 111 and second scanner 112 read, and send behind title shown in additional Figure 10 (A) and the footer shown in Figure 10 (C).

Then, driver 213 is judged all reads image data (step ST7) in the zone of whether receiving a piece or a reading object, (step ST7 :) do not turn back to step ST1, receive next packet when not receiving.Have again; When receiving a reads image data whole (step ST7: be); The data that are kept in the video memory 212 are constituted one group of reads image data (step ST8), and, finish and to handle to application program 214 output these reads image data (step ST9).
Like this, the data that packet comprised of in reception buffer 211, preserving are under the situation of mirror image data, are saved in the video memory 212 after utilizing the function of driver 213 to make its upset, thus driver 213 reads image data of making erect images.At this moment; The reads image data no matter click type printer 10 sends is erect image or mirror image; Through eliminating this different part the step that received data is transplanted on video memory 212 from reception buffer 211, can be all the time to application program 214 output erect images.Therefore, can not produce the problem that the processing time is elongated or the processing load is excessive, can obtain towards correct reads image data.Have again; Shown in Figure 10 (A)～(C); Click type printer 10 needs only the generation expression and is the erect image or the packet of mirror image and sends; Therefore can in the load of inhibition point hit printer 10, distinguish erect image and mirror image, can in master computer 200, obtain towards correct reads image data.
And then; Because each packet according to receiving from click type printer 10 is differentiated erect image or mirror image; Even, also can generate exactly and obtain towards correct reads image data so mix with the packet of mirror image under the situation about existing at the packet of hypothesis erect image.
Have again, also can after having received all reads image data, carry out the above-mentioned reads image data upset that makes mirror image and be the processing of erect image.
Figure 12 is the flow chart of example of the action of expression master computer 200.
Shown in Figure 12 like this, master computer 200 utilizes the function of driver 213, will press through the packet (step ST11) that interface 202 receives and receive sequential storage (step ST12) in reception buffer 211.Driver 213 is judged all reads image data (step ST13) in the zone of whether receiving a piece or a reading object, (step ST13 :) do not turn back to step ST11, receive next packet when not receiving.
Have again; When receiving a reads image data whole (step ST13: be); Driver 213 with reference to or obtain the information (step ST14) of the data arrangement order that the title portion of the packet of in video memory 212, preserving comprised, differentiating received data arrangement is erect image or mirror image (step ST15) in proper order.
Be that (step ST15: not), driver 213 makes its upset after from reception buffer 211, reading all images data, and the view data that generates erect image also is saved in (step ST16) in the video memory 212 under the situation of mirror image in the data arrangement order.In this step ST16, overturn after from reception buffer 211, reading the reads image data of mirror image, then as the storage of erect image in video memory 212.
On the other hand, in the data arrangement order (step ST15: be) under the situation of erect image, driver 213 stores (step ST17) in the video memory 212 into after from reception buffer 211, reading all images data.Thus, the view data of storage erect image in video memory 212.
Then, driver 213 finishes and should handle to the reads image data (step ST18) of application program 214 output image memories 212.
Like this; In case receive all packets that constitute a reads image data; Just be saved in the reception buffer 211; After all reads image data of arrangement, differentiating is erect image or mirror image, makes the processing of image upset as required, and in video memory 212, stores the reads image data of erect image.Thus; Same with action shown in Figure 11; The reads image data no matter click type printer 10 sends is erect image or mirror image; The step that received data is transplanted on video memory 212 from reception buffer 211, can eliminate this different part, can be all the time to application program 214 output erect images.Therefore, can not produce the problem that the processing time is elongated or the processing load is excessive, can obtain towards correct reads image data.Have again; Shown in Figure 10 (A)～(C); Click type printer 10 needs only the generation expression and is the erect image or the packet of mirror image and sends; Therefore can in the load of inhibition point hit printer 10, distinguish erect image and mirror image, can in master computer 200, obtain towards correct reads image data.And then differentiation is that erect image or the action of mirror image need for a reads image data are once just passable, therefore can generate quickly and obtain towards correct reads image data.
Figure 13 is the flow chart of the action of the click type printer 10 that relates to of this execution mode of expression.
At first; If recording medium S is inserted into manual insertion mouth 15; And detect the front end (step S1: be) of recording medium S by media end transducer 47; Then the CPU40 of click type printer 10 makes in the transfer path P of alignment plate 38 in recording medium S and gives prominence to, and makes 26 work of medium transmission motor and make recording medium S alignment (step S2).
Then, to differentiate detected recording medium S be check or bankbook (step S3) to CPU40.At this; CPU40 also can obtain the information of sending from master computer 200; And judge the kind of recording medium S based on this information; Perhaps utilize media end transducer 47 or the front end of medium width sensor 55 detection record medium S or the position of side, judge the kind of recording medium S based on this position or size.Have again; Also can be based on utilizing media end transducer 47 or the front end of medium width sensor 55 detected recording medium S or the position of side; By reading of magnetic 34 a tentative MICR information; Try whether have MICR information among the determinating area MA through what this read, differentiate the kind of recording medium S thus.In this execution mode, CPU40 obtains from master computer 200: the information that is used for the kind (check or bankbook) of definite recording medium S; For example relevant information, the information relevant, the information relevant when recording medium S is check with transmitting range with the position of regional MA with the size of check, and differentiate check or bankbook based on these information.
Not (step S3: not) under the situation of check at recording medium S; CPU40 for example differentiate for recording medium S be bankbook; Be located at reading of magnetic stripe on the bankbook; Therefore till recording medium S being sent to the position that can be read by magnetic 34, by magnetic 34 carry out magnetic stripes read with and/or write (step S4).And then CPU40 is sent to recording medium S till the position of recording head 18, by the record (step S5) that recording head 18 is carried out to recording surface, discharges these recording mediums (step S6), tenth skill from manual insertion mouth 15.
Be (step S3: be) under the situation of check at recording medium S, CPU40 judges the reading order (step S7) that whether receives MICR information from master computer 200.And; CPU40 is (step S7: be) under the situation that is judged to be the reading order that has received MICR information; Alignment plate 38 is kept out of the way from transmitting path P; And by media transportation mechanism 100 with recording medium S be sent to the front end of recording medium S at least arrive at medium width sensor 55 under till after, driving arm drive motor 56 (Fig. 6) is along main scanning direction scanning bracket 19; Based on the position from the main scanning direction of the output signal of medium width sensor 55 and support 19, the position (step S8) of the Width of detection record medium S.And then, on one side CPU40 makes media transportation mechanism 100 transmit recording medium S, Yi Bian the output signal of monitoring media end sensor 47, the back-end location (step S9) of detection record medium S.
Then; CPU40 utilizes media transportation mechanism 100 to transmit recording medium S; Till the position that can read regional MA by magnetic 34 (step S10); Control motor driver 46 also makes 57 work of a magnetic drive motor, is carried out read (the step S11) of the MICR literal that is presented in the regional MA by magnetic 34.Information (MICR information) by magnetic 34 reads is carried out digitlization by gate array 45, and CPU40 obtains this numerical data (step S12), based on this data analysis Word message, converts text message (step S13) into.At this; Judge unanalyzable literal to surpass predefined number and exist still in the scope of predefined number and analyzed success (step S14); (step S14: not) under the situation that has the unanalyzable literal existence that surpasses the number that sets; Output error is also discharged recording medium S (step S15), tenth skill.In step S15, display part untill further notice mistake itself that also can utilize click type printer 10 to be possessed takes place, and can also send the wrong information that takes place of expression to master computer 200, perhaps also can all carry out by this dual mode.
On the other hand; When the number of unanalyzable literal does not surpass the number that sets and analyzes successfully (step S14: be), CPU40 carries out the scanning based on optical pickup device 110, sends reads image data (step S16) to master computer 200; Standby is to till the fill order of master computer 200 reception endorsement printings (step S17); Under the exectorial situation that receives the endorsement printing (step S17: be), make medium transmit motor 26 counter-rotatings, recording medium S is sent under the recording head 18; And driving arm drive motor 56 and recording head 18 are represented the endorsement printing (step S18) of finishing dealing with at the back side of recording medium S.And, if the printing of endorsing finishes, then further make medium transmit motor 26 rotations at CPU40, recording medium S is discharged from manual insertion mouth 15 or outlet 20.
Figure 14 is the performed flow chart that reads action of expression click type printer 10, illustrates in greater detail the action shown in the step S16 of Figure 13.
CPU40 receives the setting command (step S21) that sends from master computer 200, obtains the various setting contents (step S22) by this setting command appointment.At this; CPU40 judges whether to have been specified by setting command the zone (step S23) of reading object; There is not under the situation of appointed area (step S23: not),, obtain the position (step S24) that becomes the piece of benchmark when reading whole read range R based on scanning direction by the setting command appointment.The position of the piece the when integral body of carrying out read range R reads for example is stored among the EEPROM42.
Have again; Under the situation in the zone of having specified reading object by setting command (step S23: be); CPU40 obtains the numbering in zone and the starting position that each is regional and the coordinate (step S24) of end position; Configuring area in read range R, and based on the scanning direction by the setting command appointment, decision is suitable for the position (step S26) of the piece in zone.
After obtaining or having determined the piece position; The CPU40 standby is to till master computer 200 reception scanning sign ons (step S27); If receive scanning sign on (step S27: be); Then based on by the scanning direction of setting command appointment, be that integral body reads or read the appointed area, be the position and the current position of recording medium S in zone specified when specifying the zone to read; By media transportation mechanism 100 recording medium S is sent to the scanning starting position (step S28) of optical pickup device 110, Yi Bian transmit recording medium S, Yi Bian carry out read (step S29) based on first scanner 111 and second scanner 112.In the implementation that this reads; The CPU40 differentiation has or not the piece (step S30) that reads end; If the piece (step S30: be) of the end of reading is arranged; Then carry out the processing (step S31) of from the frame buffer of RAM41, reading the reads image data of this piece and being transferred to master computer 200, if pass on ends, the reads image data of interior this piece of deleted image buffer then.CPU40 differentiates reading of all pieces and whether finishes (step S32), reads unclosed (step S32: not), then turn back to step S29 and continue to read action, if operate the new piece that reads end, then pass on the reads image data of this piece if exist.
Afterwards, if the reading all of all pieces among the read range R on this two sides, the positive back side finished (step S32: be), then finish to read action.
In addition, as stated, the linear imaging sensor 112A of the linear imaging sensor 111A of first scanner 111 and second scanner 112 departs from configuration, in this execution mode, and linear imaging sensor 111A deflection front side 5mm.Therefore, carry out in the clockwise direction under the scan condition, the read range R of upper surface reads than the read range R completion earlier of lower surface, carries out under the scan condition in the other direction, and the read range R of lower surface reads than the read range R completion earlier of upper surface.
Have, in the processing of above-mentioned step S31 (Figure 14), click type printer 10 carries out Figure 11 or action shown in Figure 12 again, also can generate the reads image data of erect image and send to master computer 200.
Under this situation; CPU40 also can be based on the scanning direction in first scanner 111, second scanner 112 and from the outbound course of first scanner 111, second scanner 112; Differentiation from the reads image data of gate array 45 input towards, carry out the upset of view data towards the mode that becomes erect image according to this.For example; Processing shown in figure 11 is such, also can be: whenever from the reads image data of corresponding 1 row of gate array 45 inputs the time, CPU40 just differentiate should towards; Overturn as required, the reads image data that is set as correspondence 1 row of erect image stores among the RAM41 afterwards.Also have; For example, processing shown in figure 12 is such, also can be: from the whole reads image data of 1 piece of gate array 45 inputs or the reads image data in a corresponding zone; CPU40 stores after these data in RAM41; Differentiate this reads image data towards, overturn as required, generate the reads image data of erect image.At this moment; Even the driver 213 that master computer 200 is possessed do not have erect image and mirror image difference, or with first scanner 111, second scanner 112 in the situation of the function corresponding positive and negative of reading direction under, the reads image data of erect image also can be provided to master computer 200.For example, this is as the part of the function of operating system 210 and under the situation of the general printed driver that is provided at driver 213, can be corresponding on the basis that can not diminish its versatility with erect image and mirror image aspect of great use.
