And whether dot matrix printer 10 is judged according to the instruction that received can conveyance bankbook 100, sends the status information according to result of determination, and can carry out conveyance (step S23) under the situation of conveyance bankbook 100.Here, the status information that dot matrix printer 10 sends for " normally ", can not carried out under the situation of indicated conveyance under the situation of the conveyance that can carry out bankbook 100 as indicated, becomes " mistake ".

Master computer 80 receives the status information (step S13) of sending from dot matrix printer 10, carries out the differentiation (step S14) of status information, is under the situation of " mistake " in status information, finishes this and handles, and carries out and wrong corresponding action.

In addition, in the status information of sending from dot matrix printer 10 is under the situation of " normally ", master computer 80 will should record the data on the bankbook 100 and indicate the instruction of executive logging to send to dot matrix printer 10 (step S15) after the conveyance, then, transfer to the processing (step S16) of data that generation should write down etc.

Dot matrix printer 10 is receiving the data of sending from master computer 80 and is indicating under the situation that writes down the instruction of carrying out (step S24), according to the data that receive, document image on bankbook 100 (step S25), then, transfer to the holding state (step S26) that is used to receive next instruction etc.

The processing of the step S11 of this Fig. 6～S16 and step S21～S26 can be for example be carried out when carrying out the record of 1 row at every turn, also can be in 1 time above-mentioned processing the merge record multirow.

In the processing of above-mentioned steps S23, can dot matrix printer 10 carry out conveyance by judging, sends status information, and can carry out conveyance under the situation of conveyance, and the conveyance that makes master computer 80 not need to wait for dot matrix printer 10 is carried out.Therefore, data and the instruction that can should write down from master computer 80 rapid transmissions, in dot matrix printer 10, owing to after receiving the data of sending and instruction, can carry out record immediately from master computer 80, so have the advantage that can improve throughput.

Below, dot matrix printer 10 performed processing in this step S23 are elaborated.

The flow chart of determination processing when the flow chart of Fig. 7 processing that to be expression carried out by dot matrix printer 10, Fig. 8 are conveyances shown in the step S51 of detailed presentation graphs 7.

These Fig. 7 and processing shown in Figure 8 are to read the control program that is stored in the flash rom 63 by the CPU61 that makes the control baseplate part 50 that dot matrix printer 10 had, and carry out this program and realize.

CPU61 at first calculates by the indicated computed carrier amount (step S41) of master computer 80, next, judges whether current record position is terminal area (step S42).Here, so-called current record position is meant the part under the record head 18 of being positioned in the bankbook 100.

Here, be under the situation in the terminal area (step S42: be) at current record position, computed carrier amount that CPU61 will calculate in step S4 and residual terminal zone, that is, the size in the zone of 100 terminal compares (step S43) from the position under the record head 18 to bankbook.

CPU61 the computed carrier amount that calculates by step S41 more than or equal to the situation that is stored in the residual terminal zone among the RAM62 under, if the computed carrier amount by appointment carries out conveyance, the terminal that then can surpass bankbook 100, institute sends status information (step S45) so that state becomes " mistake " (step S44) to master computer 80.On the other hand, (step S43: not) under the situation of computed carrier amount less than the residual terminal zone, the residual terminal zone of CPU61 from be stored in RAM62 deducts computed carrier amount, as new residual terminal zone (step S46), and new residual terminal area update is stored among the RAM62, and make state become " normally " (step S47), send status information (step S48) to master computer 80.And CPU61 makes 36 actions of conveyance motor, according to the computed carrier amount conveyance bankbook 100 (step S49) that calculates by control drive circuit 66 in step S41.

In addition, not that (step S42: not), CPU61 will compare (step S50) in computed carrier amount and the terminal area that step S41 calculates under the situation of terminal area in current location.

Here, (step S50: not), CPU61 forwards above-mentioned step S47 to, makes status information become " normally ", and sends status information under the computed carrier amount situation littler than the terminal area.

On the other hand, under the situation of computed carrier amount (step S50: be) more than or equal to the terminal area, promptly, computed carrier amount surpasses under the situation of the distance shown in the symbol D among Fig. 4, CPU61 carries out the bankbook of conveyance on one side 100, on one side determination processing (step S51) when judging the conveyance of the conveyance that can carry out specified computed carrier amount.

Below, with reference to Fig. 8, determination processing is elaborated during to the conveyance of this step S51.

In the determination processing, CPU61 is setup parameter N (positive integer) at first when conveyance shown in Figure 8, and as this parameter N, the computed carrier amount that setting will calculate at the step S41 of Fig. 7 is converted into the value (step S61) of step number.

Next, CPU61 carries out the judgement (step S62) whether current location is positioned at the terminal area, under the situation beyond current location is positioned at the terminal area, holds detecting sensor 52 whether to detect the judgement (step S63) of the terminal of bankbook 100.

Here, if do not detect the terminal of bankbook 100, then CPU61 drives control drive circuit 66, makes 36 actions of conveyance motor, carries out the conveyance (step S64) of the bankbook 100 in 1 step.This 1 step is meant, for example constitutes the actuating quantity of least unit of the conveyance motor 36 of stepper motor.Then, CPU61 deducts 1 (step S65) from parameter N, and whether critical parameter N becomes 0 (zero) (step S66).Become in parameter N under 0 the situation, enter step S76 described later,, then return step S63 if parameter does not become 0.

Then, by in the action of step S64～S65, conveyance bankbook 100, detect by end detecting sensor 52 under the situation of terminal of bankbook 100 (step S63: be), CPU61 will be stored in the size (the symbol D among Fig. 4) (step S67) that residual terminal zone among the RAM62 is set at the terminal area, and will represent that the information that current location is arranged in the terminal area stores RAM62 (step S68) into, returns step S62 then.

In step S62, under current location entered situation in the terminal area, CPU61 judged whether the residual terminal zone that is stored among the RAM62 becomes 0 (zero) (step S69).Here, if the residual terminal zone is not 0 (step S69: deny), then CPU61 drives control drive circuit 66 and makes 36 rotations of conveyance motor, carries out the conveyance (step S70) of the bankbook 100 in 1 step.Next, deduct the amount (step S71) of institute's conveyance in the residual terminal zone of CPU61 from be stored in RAM62, enter step S74 described later.Here, determine under the situation in residual terminal zone that CPU61 deducts institute's conveyance from the residual terminal zone step number (1 step) gets final product in the action step number of corresponding conveyance motor 36.

In addition, be under 0 the situation, not have " the no medium mark " in the zone of writing down in the bankbook 100 to be arranged to " 1 " expression in the residual terminal zone, and be stored in (step S70) among the RAM62, and 1 (step S73) is set in parameter N, enters step S74 then.

In step S74, CPU61 subtracts 1 with parameter N to be upgraded.Next, whether CPU61 critical parameter N is 0 (step S75).Here, if parameter N is not 0, then CPU61 returns step S69, carries out the processing of substep conveyance bankbook 100, become 0 up to the residual terminal zone, or the parameter N that sets in step S61 becomes till 0.

Then, become in parameter N under 0 the situation (step S75: be), CPU61 judges whether stored " no medium mark " in flash rom 63, and its value is " 1 " (step S76).At " no medium mark " is under the situation of " 1 ", can not carry out in step S61, being set in the conveyance of the conveyance step number in the parameter N, so CPU61 makes state become " mistake " (step S77), status information is sent to master computer 80 (step S78), finish this processing then.Here, in dot matrix printer 10, though conveyance bankbook 100 because state is mistake,, receive indications such as sending page or leaf from master computer 80 so current page is not carried out record, therefore, no problem fully in practical application.

On the other hand, not (step S76: not) under the situation of " 1 " in the value of " no medium mark ", can carry out the conveyance of the step number that step S61 sets in parameter N, so CPU61 makes state become " normally " (step S79), send status information (step S80) to master computer 80, finish this processing then.

By above Fig. 7 and processing shown in Figure 8, dot matrix printer 10 is under the situation of the conveyance indication that receives bankbook 100 from master computer 80, can promptly judge the conveyance that to carry out according to indicated amount according to the distance (the symbol D among Fig. 4) between end detecting sensor 52 and the record head 18.

And, under situation about can carry out according to the conveyance of indicated amount, after status information is sent to master computer 80, conveyance bankbook 100.Thus, during dot matrix printer 10 conveyance bankbooks 100, master computer 80 can receiving status information, carry out the processing of the expansion etc. of the data that should write down, therefore, dot matrix printer 10 and master computer 80 separately in, can shorten the time that the information of waiting for the other side sends.Therefore, can carry out the conveyance and the record of bankbook 100 expeditiously, improve throughput.And, when conveyance bankbook 100, because determination processing (step S51) when not needing to carry out conveyance, as long as carry out a conveyance, so can improve conveyance efficient according to master computer 80 indicated computed carrier amounts.

In addition, under situation about can not carry out according to the conveyance of the amount indicated by master computer 80, because dot matrix printer 10 sends status information rapidly, so have the advantage that can promptly carry out by the processing afterwards of sending page or leaf or indication discharge bankbook 100 etc. of 80 pairs of dot matrix printers of master computer, 10 indication bankbooks 100, this advantage is very favourable to improving throughput.

And can under the situation that is difficult to judge the conveyance that carry out the amount indicated according to master computer 80, dot matrix printer 10 can actual on one side substep conveyance bankbook 100, Yi Bian judge.Thus, not only can promptly judge, and if under situation about can carry out according to the conveyance of indicated amount, can after promptly carry out operation of recording.Therefore, can promptly judge can conveyance in, omits the invalid stand-by period, the raising throughput.

Specifically be, detecting under the state of bankbook 100 that under the situation littler than the terminal area by the computed carrier amount of master computer 80 indications, CPU61 is judged to be and can carries out conveyance by end detecting sensor 52.Can promptly judge in the case, conveyance.And, CPU61 can conveyance the amount of bankbook 100 under the record head 18 as the residual terminal area stores in RAM62, after end detecting sensor 52 can not continue to detect bankbook 100, according to after computed carrier amount upgrade the residual terminal zone.Thus, but owing to store the size of the bankbook 100 of conveyance in advance, so can be rapidly and judge the conveyance that can carry out according to by the indicated amount of master computer 80 effectively.

In addition, even after end detecting sensor 52 can not continue to detect bankbook 100, carry out under the situation of repeatedly conveyance, because but the size of the bankbook 100 of conveyance is updated storage successively, so can be rapidly and judge the conveyance that to carry out according to by the indicated amount of master computer 80 effectively.

In addition, CPU61 detects under the state of bankbook 100 in end detecting sensor 52, under the situation of the computed carrier amount of having been indicated the size that has surpassed the terminal area by master computer 80, substep conveyance bankbook 100 is till end detecting sensor 52 detects less than bankbook 100.Thus, even under the situation that is difficult to judge the conveyance that to carry out the amount indicated, also can judge effectively and can carry out the conveyance of bankbook 100 according to master computer 80.

In addition, in the step S43 and the processing shown in the S50 of above-mentioned Fig. 7, illustrated that CPU61 judges computed carrier amount whether more than or equal to the situation in residual terminal zone, but the invention is not restricted to this, for example can judge also whether computed carrier amount surpasses the residual terminal zone.In addition, in the step S64 and S70 of Fig. 8, illustrated that CPU61 makes the situation of conveyance motor 36 substep rotations, but the invention is not restricted to this, for example also can make it divide 2 steps or the above action of 2 steps.

And, in the above-described embodiment, for example understand and to hold detecting sensor 52 to be arranged on, but the invention is not restricted to this, also end detecting sensor 52 can be arranged on than permutation plate 54 more close record head 18 sides than the more close manual structure of inserting mouthful 15 sides of permutation plate 54.But adopt the illustrational structure of above-mentioned embodiment, have when making bankbook 100 withstand on the permutation plate 54 permutation, can carry out the advantage of permutation status detection by end detecting sensor 52.

In addition, in the above-described embodiment, the structure that dot matrix printer 10 is connected with master computer 80 has been described, but the quantity of this master computer 80 has been had no particular limits, many master computers 80 can be connected with dot matrix printer 10.In addition, in the above-described embodiment, the situation that applies the present invention to dot matrix printer 10 has been described, but the invention is not restricted to this, go for the various tape decks (printer) such as thermal printer, heat transfer type printer of ink-jet printer, laser printer, use temperature-sensitive thin slice, and go for being assembled into the tape deck in other equipment (duplicator etc.).In addition, other concrete structures about in the above-mentioned embodiment certainly change arbitrarily.
