Description

  The present invention relates to a printing apparatus including a conveyance unit that conveys a print medium on a conveyance path and a printing unit that performs printing on the print medium, and in particular, a print head movement including a carriage that moves the print head. The present invention relates to a printing apparatus having a mechanism and a printing method thereof.

  Payment systems using checks are widely used, mainly in Europe and the United States. Various payments and remittances are made by sending and receiving checks, and these checks are finally brought to the bank for payment and cashing.

  For this reason, it is necessary to process a large amount of checks in a short time at the counter of each bank branch. The main processing at the branch office is that the bank clerk checks the check itself, checks the date, verifies the signature, etc., then deposits and cashes. In this case, endorsement is made on the obtained check and a receipt is issued if necessary.

  In recent years, attempts have been made to electromagnetically read checks brought into banks, and in the future, they are trying to improve business efficiency by connecting online between branches and banks. .

  Therefore, many branches of each bank currently have a magnetic ink character reader (MICR) for reading magnetic ink information written on checks, and an image reader for reading checks into images ( A processing facility equipped with a scanner is provided. This processing machine is a large facility that processes a large amount of checks at high speed and cannot be placed at a bank window. Therefore, usually, a considerably large space dedicated to check processing is secured inside the bank, and check processing is performed there. After this processing, checks collected for each branch are transported by a transport vehicle or the like and collected in a predetermined storage location.

  Attempts have also been made to perform the above-described electromagnetic reading work of checks at the counter. For this reason, a small processing apparatus (for example, described in Patent Document 1) that can be installed at a window has been proposed. This processing apparatus has a check conveyance mechanism, and a MICR (Magnetic-Ink Character Reader), a scanner, and a printing apparatus are provided on the conveyance path.

  When the bank clerk who received the check from the customer passes the check through the processing device, the processing device reads the check with the MICR or the scanner, and writes the endorsement on the check with the printing device.

JP 2000-344428 A

  In this processing device, the inserted check data is read by a detector such as MICR or a scanner, and then the check is endorsed continuously. Therefore, even if a reading error occurs by these detection devices, the check endorsement is performed as it is. Therefore, this endorsement becomes invalid and must be reapplied to the processor, resulting in multiple endorsements on a single check.

  In addition, after passing through the processing device, the bank clerk at the counter uses the check itself or the image read by the scanner to verify the date and signature written on the check and perform a predetermined check. Similarly, if a problem is discovered in, the endorsement is invalid. Therefore, after finishing a predetermined correction work, it is necessary to apply this processing apparatus again, or to endorse again with a separate printing apparatus.

  To solve this problem, it is necessary to stop the check once after reading with MICR and the scanner and before endorsing. Then, after the result of reading by this detector and the result of the bank clerk checking the image read by the scanner are found, it is necessary to start the check again and perform the endorsement according to the result.

  If this is to be done with a single device, it is necessary to place the print head after the position where the check has been transported and the steady speed has been reached since the transport of the check has been stopped. Therefore, it is necessary to extend the length of the conveyance path, and it is very difficult to realize it, considering the very limited space of the bank window.

  If it is determined that there is no problem as a result of this check, a payment or deposit processing procedure is performed, but it is necessary to use a new device other than the above-described processing device. In other words, it is necessary to input to a terminal of a separately installed computer and issue a receipt to be given to a customer or create a copy of a branch office using a printing device different from the above processing device. .

  In summary, with a conventional processing apparatus, even if a reading error or other malfunction occurs in the MICR or scanner, the check is endorsed as it is. In that case, it is necessary to invalidate the endorsement and perform the processing again with the processing device or with another device. Therefore, since multiple endorsements are made on one check, the risk of misidentification increases and the reliability decreases. In addition, the work efficiency is also reduced because the duplicate work must be performed again.

  In addition to processing the check through the processing device, it is necessary to input data to another device and print receipts using another printing device. Therefore, quick processing is not possible.

  In addition to this processing apparatus, it is necessary to install another printing apparatus. This imposes pressure on the limited work space of the counter and deteriorates the efficiency of processing operations. This is a major problem for banks that have to deal accurately and quickly with limited window space. In addition, it is a common problem not only in banks but also in the business of processing checks and other forms in a limited space.

  Accordingly, an object of the present invention is to solve the conventional problems described above and provide a printing apparatus capable of printing by feeding back the result of reading the data of the print medium with a detector and the result of other checks. There is to do. It is another object of the present invention to provide a compact printing apparatus and printing method that can perform not only processing and printing of forms such as checks but also subsequent printing of receipts and the like with a single machine.

  The print head 14 can perform printing on both the cut sheet S that moves in the horizontal direction and the roll paper P or the cut sheet S that moves in the vertical direction, which will be described later. The print head 14 has a plurality of nozzles, and can print at least one line of characters on the cut sheet S that moves in the horizontal direction without moving the carriage 15.

  On the downstream side of the print head 14, a discharge unit 4 including a discharge roller 8 is provided. The discharge unit 4 discharges the cut sheet S that has been printed to the outside of the printing apparatus 1 via the discharge roller 8. Further, a discharge detector 28 is provided in the vicinity of the discharge roller 8, and it is possible to confirm whether or not the cut sheet S for which printing has been completed is discharged. The discharge detector 28 also serves to detect the discharge of the cut sheet S transported and printed along a third transport path P3 to be described later. As shown in FIG. 6, the first transport path P1 For both of the third transport paths P3, they are arranged downstream of the printing area 18.

  In the present embodiment, the height of the outer guide 2a and the inner guide 2b is larger than the width of the cut sheet S to be transported at a place other than the U-shaped bottom portion 34 where the scanners 11 and 12 and the MICR 13 are installed. When the paper jam occurs, it can be easily removed by hand.

  Next, the conveyance of the cut sheet S in the first conveyance path P1 will be described. The cut sheet S is set by the user from the direction of the arrow A in the paper feeding unit 3 provided in the straight portion 35a of the first transport path P1. The cut sheet S is conveyed from the sheet feeding unit 3 along the first conveyance path P1.

  When the leading edge of the cut sheet S set by the user reaches the BOF detector 9, the BOF detector 9 detects the leading edge of the cut sheet S. When the printing apparatus 1 has received a processing command for the cut sheet S from a host computer (not shown), the driving roller 6 a of the first transport roller 6 rotates according to the detection of the BOF detector 9. start. The cut sheet S is smoothly sandwiched between the driving roller 6a and the pressing roller 6b, and is not slipped by the rotation of the driving roller 6a. 2a is conveyed along the wall.

  When the leading edge of the cut sheet S transported by the first transport roller 6 reaches a TOF (Top of Form) detector 10, the scanners 11 and 12 and the MICR 13 installed at the tip thereof are turned on. The printing apparatus 1 according to the present embodiment supplies power to necessary parts only when necessary, including driving of rollers, and is configured to prevent wasteful power consumption.

  Further, when the cut sheet S is conveyed, the scanner 11 installed on the outer guide 2a reads an image on the back side of the cut sheet S, and the scanner 12 installed on the inner guide 2b side An image on the surface of the paper S is read. Further, the MICR 13 installed on the inner guide 2b side reads magnetic ink character information previously written on the cut sheet S.

  The image data generated by the scanners 11 and 12 can be transferred to a host computer that controls the printing apparatus 1, and a predetermined process is performed by an arithmetic processing unit provided in the printing apparatus 1. May be. Further, the read image may be displayed on the display so as to improve the efficiency of checking the cut sheet S such as a check. As this display, a display installed in the host computer can be used, or it can be installed in the printing apparatus 1 itself.

  These fetched data are processed by a processing device in the printing apparatus 1 or a connected host computer. And according to the result of a data processing, you may comprise so that it prints on the roll paper P which is a 2nd printing medium, and another sheet paper S which is validation paper.

  When the leading edge of the cut sheet S reaches the second conveying roller 7 after passing through the TOF detector 10, it is sandwiched between the driving roller 7a and the pressing roller 7b, and the straight portion 35b is rotated by the rotation of the driving roller 7a. Sent to the side.

  Then, the print head 14 performs printing on the cut sheet S when passing through the print area 18 that is in close proximity to the print head 14. There is an outer guide 2a between the print head 14 and the cut sheet S, but in this print region 18, an opening is widened in the outer guide 2a, and between the print head 14 and the cut sheet S, There are no obstacles.

  In the present embodiment, the printing head 14 is fixed at a predetermined position in the printing area 18 at the time of printing, and predetermined printing is performed by moving the cut sheet S as a printing medium. It has become. Note that the print head 14 can be retracted to the retreat position 19 together with the carriage 15 when not necessary for printing. Therefore, when printing is not performed, the print head 14 is retracted, so that the print head 14 is not damaged by the transported cut sheet S or the transported cut sheet S is not stained. Further, when the print head 14 is retracted, the possibility that the cut sheet S or the like is jammed is reduced.

  The cut sheet S printed on the back side by the print head 14 is discharged in the direction of arrow B by the discharge roller 8, and the driving roller 8a rotates while being sandwiched between the driving roller 8a and the pressing roller 8b. By doing so, it is sent out of the printing apparatus 1. This completes the process related to the cut sheet S. The above is the description regarding the first transport path.

(Second transport path)
Next, the 2nd conveyance path P2 is demonstrated, referring Fig.2 (a), FIG.5 and FIG.6.

  5 is a cross-sectional view taken along the line V-V in FIG. 4, and FIG. 6 is an enlarged view of FIG. 5. A roll paper storage unit 20 that stores the roll paper P is provided between the two straight portions 35a and 35b of the first transport path P1. One end of the roll paper P is drawn from the roll paper storage unit 20 to the second transport path P2, and is transported along the second transport path P2.

  As shown in FIG. 2A, FIG. 5 or FIG. 6, the second transport path P2 is a roll paper transport path that transports the roll paper P from the roll paper storage unit 20 toward the printing region 18 and discharges it. Yes, formed between the straight portions 35a and 35b. The second transport path P2 is a vertical transport path that overlaps with a part of the straight portion 35b of the first transport path P1 and that is substantially perpendicular to the transport direction of the first transport path P1.

  In the second transport path P2, as shown in FIG. 6, a vertical drive roller 22 that transports the roll paper P in the vertical direction, a vertical pressing roller 23 that presses the roll paper P against the vertical drive roller 22, and printing A second transport device is provided that includes a tension roller 30 that applies a predetermined tension to the roll paper P exposed in the region 18.

  These vertical drive rollers 22 are attached to the front end portion of an opening / closing lid 25 that opens and closes the roll paper storage unit 20 as shown in FIG.

  Between the vertical driving roller 22 and the vertical pressing roller 23 and the tension roller 30, the platen 24 and the print head 14 disposed in the printing area 18 are disposed on both sides of the second transport path P2. Further, a roll paper discharge port 36 for discharging the roll paper P is opened above the vertical drive roller 22 and the vertical pressing roller 23, and a cutter 26 for cutting the roll paper P is provided near the roll paper discharge port 36. Is arranged.

  Next, the conveyance of the roll paper P in the second conveyance path P2 that is the roll paper conveyance path will be described. One end of the roll paper P drawn out from the roll paper storage unit 20 passes through the tension roller 30 and the platen 24 and is set in advance so as to be sandwiched between the vertical driving roller 22 and the vertical pressing roller 23. The roll paper P is conveyed upward along the second conveyance path P <b> 2 by the rotation of the tension roller 30, the vertical driving roller 22, and the vertical pressing roller 23. Then, printing on the roll paper P is performed via the print head 14 when passing through the print area 18 that is in close proximity to the print head 14.

  Here, in printing on the roll paper P, when the print head 14 performs one line printing while moving in the horizontal direction via the carriage 15 and it is necessary to print a plurality of lines, the vertical direction is obtained after the completion of the one line printing. The drive roller 22 is rotated to feed the roll paper P upward by one line, and then the print head 14 is moved again in the horizontal direction to perform printing for the second and subsequent lines. A predetermined tension is applied between the tension roller 30, the vertical drive roller 22, and the vertical pressing roller 23, and the roll paper P is conveyed to the printing position without sagging.

  Then, the roll paper P is further conveyed upward and discharged from the roll paper discharge port 36 to the outside of the printing apparatus 1. Further, the discharged roll paper P can be cut by a cutter 26 disposed in the vicinity of the roll paper discharge port 36.

  Print data received from the host computer is printed on the roll paper P. In addition to the print data received from the host, the data read by the scanners 11 and 12 and the MICR 13 or data obtained by processing the data can be printed. That is, the printing apparatus 1 can print on the roll paper P based on the data acquired by the printing apparatus 1 itself. Therefore, a series of processing operations can be performed quickly.

  Further, when printing is performed on the cut sheet S in the first transport path P1 and the third transport path P3 described later, the cut sheet S exists between the roll sheet and the print head 14. Is confirmed by the discharge detector 28 or the later-described validation detector 27, the print data to be printed on the cut sheet S is not likely to be printed on the roll paper P. When it is necessary to print on the roll paper P, it is possible to perform printing on the roll paper P immediately after it is detected that the cut sheet S has passed or removed. Efficiency can be increased.

(Third transport path)
Next, the 3rd conveyance path P3 is demonstrated, referring FIG.2 (b) and FIG.

  The third transport path P3 is provided corresponding to the print head 14 disposed in the print region 18, and the outer guide 2a from the upper opening 37 formed between the outer guide 2a and the inner guide 2b in the vicinity of the print region 18. This is a transport path for transporting the cut sheet S which is a validation paper inserted between the inner guide 2b and the inner guide 2b. In the third transport path P3, the second transport path and a part of the transport path overlap, and the first transport path P1 and the transport direction are substantially orthogonal to each other, like the second transport path P2. That is, the third transport path P3 is a vertical transport path that is orthogonal to the first transport path P1 together with the second transport path P2.

  The third transport path P3 includes a validation drive roller 31a and a validation pressing roller 31b that are arranged to face both sides of the third transport path P3. The validation drive roller 31a is disposed below the platen 24 and the tension roller 30, and can transport the cut sheet S up and down along the third transport path P3. The pair of rollers 31a and 31b may be referred to as a vertical discharge roller 31. ) Selectively by the validation drive roller 31a, the vertical drive roller 22 for transporting the roll paper P, and a single vertical paper feed motor (not shown) (hereinafter simply referred to as VF motor). Driven. That is, the validation drive roller 31a and the vertical drive roller 22 are selectively connected to the VF motor by a clutch (not shown). In the present embodiment, it is determined whether the power of the VF motor is transmitted to the validation drive roller 31a or the vertical drive roller 22 by moving the carriage 15 to a predetermined position.

  Further, the validation pressing roller 31b is attached to the tip of the rotating arm 31c as shown in FIG. Then, by driving an actuator (not shown), the rotary arm 31c is rotated, and the validation pressing roller 31b is in a closed position (conveying position) in contact with the validation driving roller 31a and in an open position (separated from the driving roller 31a). The retreat position can be taken. When the cut sheet S is transported along the first transport path P1 or when the cut sheet S is inserted from above, the validation pressing roller 31b is held in the retracted position.

  In addition, a validation detector 27 is installed in the vicinity of the bottom of the third transport path P3 to detect that the cut sheet S has been inserted into the third transport path P3. As shown in FIG. 3, a positioning guide for inserting the cut sheet S, which is a validation sheet, into the third transport path P3 at the connecting portion between the straight portion 35b of the first transport path P1 and the U-shaped bottom portion 34. 29 is provided. The validation detector 27 is provided to confirm whether or not the cut sheet S is set at a predetermined position. That is, the validation detector 27 detects that the cut sheet S has been set along the positioning guide 29 to the bottom of the third transport path P3. Further, when the cut sheet S is inserted into the third transport path P3, the cut sheet S is also detected by the discharge detector 28 at the same time. As described above, by using the two detectors 27 and 28 arranged with the print region 18 in between, a sheet having a size larger than a predetermined size can be inserted, and a single sheet having a size not larger than an unacceptable size. It is possible to prevent the paper S from being erroneously printed.

  Next, an example in the case where validation printing is performed on the cut sheet S such as a form via the third conveyance path P3 will be described. The cut sheet S is inserted from the upper opening 37 into the third transport path P3 which is the validation transport path. The cut sheet S is inserted to the bottom of the third transport path P3 without interfering with the validation drive roller 31a and the validation pressing roller 31b. At this time, the pressing roller 8b of the discharge roller 8 is also held in the retracted position, and the cut sheet S is inserted to the bottom of the third transport path P3 without interfering with the discharge roller 8. Is done.

  When the validation detector 27 detects that the cut sheet S has been inserted to the bottom of the third transport path P3 in a state where the printing apparatus 1 has received a command for instructing validation printing from the host computer, validation pressing is performed. The roller 31b moves from the retracted position to the transport position and sandwiches the cut sheet S with the validation drive roller 31a. At the same time, the discharge detector 28 also detects the presence or absence of the cut sheet S. Only when the cut sheet S is detected by both the validation detector 27 and the discharge detector 28, the validation pressing roller 31b is moved from the retracted position to the transport position, and the cut sheet S is detected by only one of them. At this time, an error is displayed by an LED (not shown) to notify the user that the cut sheet S is not set at a predetermined position.

  Then, as shown in FIG. 7, the carriage 15 is moved in the horizontal direction, and printing is performed on the cut sheet S sandwiched between the validation pressing roller 31 b and the validation driving roller 31 a by the print head 14. Thereby, printing for one line is performed at a predetermined position (distance from the bottom of the third transport path P3 to the printing area 18) from the lower end of the cut sheet S. When further printing is performed, the validation drive roller 31a is rotated, the cut sheet S is conveyed upward by one line, the carriage 15 is moved again in the horizontal direction, and the print head 14 prints the second line. Do.

  After the printing is finished, the cut sheet S is further conveyed upward, and the cut sheet S is detached from the validation pressing roller 31b and the validation drive roller 31a, and the user is exposed from the upper opening 37. The cut sheet S can be taken out. That the cut sheet S has been taken out by the user is confirmed by the output of the discharge detector 28. Thus, a series of printing (validation printing) on the cut sheet S is completed.

  As described above, the printing apparatus 1 according to the present embodiment has the U-shaped first conveyance path P1 in which the inserted sheet S is returned in a U-turn. After the cut sheet S is inserted and predetermined processing is performed on the conveyance path, the cut sheet S can be easily taken out. In addition, since the second transport path P2 orthogonal to the first transport path P1 is provided, it is possible to install roll paper used for receipts or the like between the U-shaped transport paths, and the operator can easily sit down. Receipts can be taken out. If necessary, another sheet paper S (validation paper) for validation may be inserted into the third transport path P3, and validation printing may be performed while sitting. Therefore, the working efficiency is greatly improved as compared with the prior art.

  According to the present embodiment, for example, when it is necessary to perform further endorsement on the check processed in the first transport path P1, the operator can quickly sit down without using another printing apparatus. Can work. Also, the check data that has already been read can be fed back to this printing.

  In summary, the printing apparatus 1 of the present embodiment conveys and discharges the first conveyance path P1 having a U-shape and the cut sheet S that is the first print medium on the first conveyance path P1. The first transport device, the second transport path P2 or the third transport path P3 that intersects the first transport path P1 substantially perpendicularly, and the roll paper P or the third paper that is the second print medium on the second transport path P2. A second transport device that transports and discharges the cut sheet S as the second print medium on the transport path P3, and on the first transport path P1 and the second transport path P2 (or the third transport path P3). At the printing position, a single cut sheet S that is a first print medium and a single print head 14 that performs printing on the roll paper P or the cut sheet S that is a second print medium are provided.

  Further, according to the present embodiment, since the first transport path P1 has a U-shape, the first print medium inserted into the first transport path P1 of the printing apparatus 1 is the first transport path. Since a U-turn is made along P1, when printing is performed and the sheet is discharged from the first conveyance path, it can be discharged next to the charged position. Therefore, a person who operates the printing apparatus 1 can easily load and remove the print medium while sitting.

  The second transport path P2 (or the third transport path P3) is substantially orthogonal to the first transport path P1, and the second print medium transported there is the same print head as the first print medium. Will be printed. Accordingly, since the second transport path P2 (or the third transport path P3) can be accommodated in the U-shaped path of the first transport path P1, two printing functions that have been impossible in the past are provided by one unit. Can be done.

  Further, according to the present embodiment, the print head 14 includes the carriage 15 that reciprocates between the print area 18 and the retreat position 19 that is separated from the print area 18 by a predetermined distance. Therefore, since the print head 14 that performs printing is in the retracted position 19 when printing is not performed, damage and contamination of the print head 14 are prevented, and the risk of paper jams due to interference between the print medium and the print head 14 is avoided. be able to.

  Further, according to the present embodiment, the printing apparatus 1 is provided with the MICR 13 that is a magnetic ink character reading apparatus that is disposed on at least one side of the first transport path P1 and reads magnetic ink information described on the first printing medium. It has been. Therefore, the printing apparatus 1 according to the present embodiment not only performs printing, but also while the cut sheet S (for example, check) as the first printing medium is conveyed on the U-shaped first conveyance path P1. Information on the magnetic ink written on the cut sheet S can be read by the MICR 13. The printing apparatus 1 can also transmit the acquired magnetic ink information (data) to a host computer, process it by a control unit (not shown) in the printing apparatus 1, and feed it back to a printing process performed later. It is.

  The printing apparatus 1 according to the present embodiment includes an image reading device (scanners 11 and 12) that is installed along the first conveyance path P1 and reads an image of the cut sheet S. Therefore, the printing apparatus 1 can capture the image of the cut sheet S with the scanners 11 and 12 installed on both sides of the first conveyance path as well as printing and reading of magnetic characters by the MICR 13. This data can be processed in the same manner as the data read by the MICR 13 described above, and this image can be displayed on a display, for example, to improve the efficiency of check checking.

  In the printing apparatus 1 of the present embodiment, the print head 14 is an ink jet printer. As a printing method, various methods can be adopted. However, a printing medium on a different conveying path of the first conveying path P1 and the second conveying path P2 (or the third conveying path P3) is used as one printing head 14. In consideration of printing with an inkjet printer, an inkjet printer is considered to be one of the optimum methods.

  As the first print medium, various media as well as paper such as the cut paper S are conceivable. However, as in the present embodiment, the cut paper S represented by a check includes a plurality of printing apparatuses. When used, there is a possibility that it may be separated, and handling becomes complicated. Therefore, efficient processing can be performed by processing the cut sheet S with the printing apparatus 1.

  In the present embodiment, printing on the cut sheet S can be performed using the third transport path P3. For example, there is a case where it is necessary to carry out the endorsement or the like again after flowing the check on the above-mentioned first transport path P1 and performing data reading or endorsement. In such a case, the printing apparatus 1 of the present embodiment performs necessary printing while receiving feedback of the read data without using another printing apparatus, by transporting the check to the third transport path P3. Is possible. Therefore, it is possible to perform an efficient process with less work mistakes than in the past.

  In the present embodiment, the cut sheet S as the second print medium loaded from the discharge side of the third transport path P3 is transported to the print position by the second transport device, and the print head is printed at the print position. It is possible to print at 14 and discharge again to the discharge side of the third transport path P3 by the second transport device. Thereby, the printing apparatus 1 of this embodiment can perform validation printing using the 3rd conveyance path P3. Conventionally, validation printing is performed by another printing apparatus. However, the printing apparatus 1 can perform all of the printing by one unit, and can use the read data as it is. Accordingly, problems such as a printing medium handling error, a data input error, and a work delay can be solved.

  Moreover, the printing apparatus 1 can use continuous paper (roll paper) wound up in a roll shape as the second print medium. Conventionally, receipts and the like have been printed by another printing apparatus, and problems such as data input errors and work delays have occurred. However, according to this embodiment, a roll is provided via the second transport path P2. By transporting the paper P, printing on the roll paper P and outputting it, it is possible to perform processing using only one printing apparatus 1.

(Mode for cut sheet printing)
The print head 14 of this embodiment is placed on the carriage 15 and can move to the print region 18 in the horizontal direction along the straight portion 35b of the first transport path P1. Accordingly, the printing on the cut sheet S transported through the first transport path P1 includes a cut sheet fixing mode in which printing is performed by moving the print head 14 in the horizontal direction while the cut sheet S is fixed. Two modes, a print head fixed mode, in which printing is performed by moving the cut sheet S in the horizontal direction with the print head 14 fixed, can be considered.

  In the print head fixed mode, the position of the print head 14 is fixed, and ink is ejected from the print head 14 to the cut sheet S passing through the front of the print head 14 to print on the cut sheet S. I do.

  In the print head fixing mode in which printing is performed while the print head 14 is fixed and the cut sheet S is moved, it is not necessary to temporarily stop the cut sheet S. Therefore, in the print head fixing mode, printing can be performed without reducing the conveyance speed of the cut sheet S conveyed from the U-shaped bottom portion 34. That is, in the print head fixing mode, the conveyance speed of the cut sheet S does not decrease, so that the high-speed cut sheet S can be processed.

  On the other hand, in the cut sheet paper fixing mode, as shown in FIG. 8B, the cut sheet S is temporarily stopped on the front surface of the print head 14, and the print head 14 is moved via the carriage 15 to the cut sheet paper. Printing on the cut sheet S is performed by ejecting ink while moving in parallel with the transport direction of S.

  This cut sheet paper fixing mode is effective, for example, when printing is performed based on the reading result of image data or magnetic ink character data read at the U-shaped bottom portion 34.

  As shown in FIG. 8A, in the print head fixing mode, when printing based on the reading result of the image data or magnetic ink character data read in the U-shaped bottom portion 34, the cut sheet S is image data. Alternatively, until the reading result of the magnetic ink character data is determined, the cut sheet S is located downstream of the position discharged from the U-shaped bottom portion 34 (more precisely, the position where reading of the magnetic ink by the MICR 13 is completed). Must be stopped once. In this case, it is necessary to install the print head 14 after the position at which the cut sheet S is resumed after the reading result of the image data or the magnetic ink character data is known and the cut sheet S enters the steady running. Therefore, in the print head fixed mode, if printing based on the reading result of the image data or magnetic ink character data is attempted, printing is not performed based on the reading result of the image data or magnetic ink character data, as compared with the case where printing is not performed based on the reading result of FIG. The length of the straight line portion 35b is increased by the length L shown in a). It is not preferable that the length of the straight line portion 35b is increased by L, which is a great obstacle for the installation of the printing apparatus 1 at a bank counter with a very limited space.

  On the other hand, as shown in FIG. 8B, in the cut sheet paper fixing mode, the cut sheet S is kept stopped by moving the print head 14 in parallel with the conveyance direction of the cut sheet S via the carriage 15. Printing on the cut sheet S is performed. In this case, the same function as the above-described FIG. 8A can be achieved with exactly the same length as the conventional transport path that does not stop the transport of the cut sheet S.

  Specifically, when the trailing edge of the cut sheet S finishes passing through the U-shaped portion 34 and enters the straight portion 35b, the conveyance of the cut sheet S is stopped. The conveyance of the cut sheet S is triggered, for example, by sheet detection by the discharge detector 28 provided at the foremost part (on the discharge roller 8 side) of the printing range, and the leading edge of the cut sheet S is moved to the discharge detector 28. You may make it stop conveyance, when it arrives. In addition, various methods such as detecting the rear end side of the cut sheet S can be adopted.

  In the cut sheet paper fixing mode as described above, if any error occurs in reading by the scanners 11 and 12 or the MICR 13, the cut sheet S is resumed without printing by the print head 14. The cut sheet S can be discharged. Thereby, for example, when the cut sheet S is a check, it is possible to prevent a problem that a conventional invalid endorsement is made.

  In the cut sheet paper fixing mode, the result of processing the read data, the result of visually checking the image read by the scanner on the display, and the like can be fed back and printed.

  In the above description, printing is performed on the cut sheet S by stopping one of the cut sheet S and the print head 14 and moving the other. However, both the cut sheet S and the print head 14 are used. It is also possible to perform printing while simultaneously moving the. In particular, the highest speed printing can be performed by moving the print head 14 to the opposite side while conveying the cut sheet S to the discharge unit 4. This is an effective means when emergency processing or the like is required.

  As described above, in the printing apparatus 1 of the present embodiment, the mode in which the print head 14 is fixed or moved in the direction parallel to the print medium conveyance direction can be selected. In particular, when the print head 14 moves in parallel with the print medium conveyance direction, various modes of printing that could not be realized conventionally can be performed by the movement of the print head.

  That is, the printing apparatus 1 of the present embodiment can perform printing by stopping the print medium and moving the print head 14 mounted on the carriage 15 in parallel with the transport direction of the print medium. . When a conventional fixed print head is used, in order to stop the conveyance of the print medium and then perform printing, the print head is installed at a position where the conveyance is resumed from the position where the print medium is stopped. It was necessary, and it was necessary to take the conveyance path to the further. However, in this embodiment, printing can be performed by stopping the print medium without extending the conventional conveyance path. Therefore, even when the installation space or work space is limited, such as a bank window, the space is not occupied meaninglessly, and the space can be used effectively.

(Selection of conveyance direction for cut sheet discharge)
In the present embodiment, the cut sheet S conveyed through the first conveyance path P1 can be configured to change the conveyance direction according to the reading result by the reading device such as the scanner 11, 12, MICR13 or the like.

  Hereinafter, an embodiment in which the conveyance direction of the cut sheet S is changed according to the reading result of the detector will be described.

  In this embodiment, the printing apparatus 1 uses the arrow B (FIG. 1) in the same direction as the previous transport direction in the straight portion 35b of the first transport path P1 according to the reading result of the scanner 11, 12 or MICR 13. Whether to discharge the cut sheet S in the direction of the reference) or whether to discharge the cut sheet S in the direction of the upper arrow C (see FIG. 1) approximately orthogonal to the previous discharge direction.

  Here, when discharging in the direction of the arrow B, it is performed by the “first discharging means” configured by the discharging unit 4 including the discharging device including the discharging roller 8 shown in FIGS. 3 and 4. Further, when discharging in the direction of the arrow C, it is performed by a “second discharge unit” configured by a discharge device including the vertical discharge roller 31 shown in FIG. 3 and a vertical transfer path (corresponding to the third transfer path P3). Is called.

  Whether the sheet is discharged by the first discharging means or the second discharging means, the cut sheet S is in close proximity to the print head 14 arranged in the printing area 18. At that time, printing on the cut sheet S can be performed. It is also possible to set so that printing is not performed when discharging in either the direction of arrow B or the direction of arrow C is selected. In the present embodiment, the print head 14 is fixed during printing, and printing is performed by moving the cut sheet. Of course, the printing head 14 may be configured to perform printing while moving.

  In the present embodiment, the cut sheet S is transported from the sheet feeding unit 3, the leading end of the cut sheet S is sandwiched between the discharge rollers 8, and is transferred from the second transport roller 7 to the discharge rollers 8. When the position is reached, the paper is detected by the discharge detector 28 installed in the vicinity of the discharge roller 8. Then, according to the detection signal output by the discharge detector 28, the conveyance of the cut sheet S can be stopped, or the discharge means for discharging the cut sheet S can be selected.

  Selection of the discharging means is performed based on whether or not a reading error of the scanner 11, 12 or MICR 13 has occurred, or whether there is a defect in other reading data. This determination is performed by an arithmetic unit installed in the printing apparatus 1. Note that the determination may be made by a host computer installed outside.

  FIG. 9A to FIG. 9C are diagrams schematically showing the movement from the time when the cut sheet S is supplied to the paper feeding unit 3 until the selection of the discharge unit.

  FIG. 9A shows that the cut sheet S is supplied to the sheet feeding unit 3. When the cut sheet S is inserted one by one, the ASF detector (not shown) is detected by the detection of the BOF detector 9 or when the cut sheet S stocked by the auto feeder is supplied. Is detected, the HF motor 40 that drives the first conveyance roller 6, the second conveyance roller 7, the discharge roller 8, and the like is activated.

  FIG. 9B shows that the cut sheet S is transported by the first transport roller 6 and the leading edge of the cut sheet S has reached the position of the TOF detector 10. Energization of the scanners 11 and 12 and the MICR 13 is started by the detection by the TOF detector 10. The subsequent positions of the cut sheet S are managed by the number of motor steps (the same applies to other embodiments).

  FIG. 9C shows a state where the cut sheet S is separated from the second transport roller 7 and is sandwiched between the discharge rollers 8. At this position, the cut sheet S is detected by the discharge detector 28, and the discharge direction is selected.

  In the present embodiment, when it is determined that there is no reading error of the scanner 11, 12 or MICR 13 or a defect in the reading data, the cut sheet S is ejected in the direction of the arrow B that is the same as the previous conveying direction, If it is determined that there is a reading error of the scanner 11, 12 or MICR 13 or a defect in the reading data, the sheet is ejected in the direction of the upper arrow C that is substantially perpendicular to the transport direction up to that point.

  The discharge in the horizontal direction is performed by a discharge roller 8 composed of a drive roller 8a and a pressing roller 8b, and the upward discharge is a vertical discharge composed of a validation drive roller 31a and a validation pressing roller 31b shown in FIG. This is done by the roller 31.

  As described above, a closed position (conveying position) where the validation pressing roller 31b contacts the validation driving roller 31a and an open position (retracting position) where the validation pressing roller 31b is separated from the validation driving roller 31a can be taken. Here, the validation drive roller 31a is disposed slightly offset from the transport line on which the cut sheet S is transported, and is installed at a position where it does not come into contact with the cut sheet S in the open position. Yes. The pressing roller 8b of the discharge roller 8 can also take a closed position (conveying position) in contact with the driving roller 8a and an open position (retracting position) away from the driving roller 8a.

  In the closed position, the validation pressing roller 31b is urged toward the validation driving roller 31a by a spring force, and the cut sheet S is sandwiched between the validation driving roller 31a and the validation pressing roller 31b. In the present embodiment, the offset from the conveyance line is very small, and there is no problem in the pinching and conveyance of the leading edge of the cut sheet S. In the initial state when the discharge direction is selected, the discharge roller 8 is in the closed position and the vertical discharge roller 31 is in the open position.

  If it is determined that there is no reading error or reading data defect, an instruction is issued to maintain the discharge roller 8 in the closed position and the vertical discharge roller 31 in the open position. Therefore, the cut sheet S is conveyed by the discharge roller 8 without contacting the vertical discharge roller 31.

  When the cut sheet S passes through the printing area 18, the print head 14 can print on the cut sheet S, or the cut sheet S can be passed through without printing. Then, the cut sheet S is conveyed as it is and discharged in the direction of arrow B.

  On the other hand, when it is determined that there is a reading error or reading data defect, first, the discharge roller 8 is instructed to take the open position from the closed position, and the horizontal conveyance is stopped. Next, the vertical discharge roller 31 is instructed to take the closed position from the open position, and sandwiches the cut sheet S. In this state, the cut sheet S is not brought into contact with the discharge roller 8 but is conveyed upward by the vertical discharge roller 31 and discharged in the direction of arrow C.

  At this time, the cut sheet S can be printed by the print head 14 when the cut sheet S is in a position in close proximity to the print head 14. In addition, by moving the cut sheet S upward, it is possible to print a plurality of lines, which is impossible with only the conventional horizontal conveyance path. Therefore, more information can be written on the cut sheet S.

  FIG. 10 is a flowchart showing a control flow from when the above-described cut sheet S is supplied to the paper supply unit 3 until it is discharged in a predetermined discharge direction. Each block connected by an arrow in the flowchart mainly indicates control of the conveyance and discharge rollers. Blocks described next to this block (blocks not connected to each other) indicate other actions performed in each step.

  First, after the printing apparatus 1 receives the processing command for the cut sheet S from the host computer, when the cut sheet S is inserted, the BOF detector 9 detects the presence of the cut sheet S and the HF motor 40 is activated. To do. Then, the cut sheet S is conveyed by the conveying device, and when the TOF detector 10 senses the presence of the cut sheet S, the scanners 11 and 12 and the MICR 13 are turned on. Thereafter, the transport position of the cut sheet S is managed by managing the number of steps of the HF motor 40 (steps S1 to S5). If the leading edge of the cut sheet S is not detected by the TOF detector even if the predetermined step (1000 step) motor is driven between step S2 and step S3, the motor is stopped and an unillustrated LED is turned on. To inform the user of a “paper transport error”. Similarly, even if the predetermined step (2400 step) motor is driven between step S4 and step S5, if the trailing edge of the cut sheet S is not detected by the TOF detector, the HF motor 40 is stopped and “ The user is notified of a “paper transport error”. Further, before and after the leading edge of the cut sheet S is detected (step S2), the speed at which the cut sheet S is conveyed is different. That is, in this embodiment, the driving speed of the HF motor 40 is 200 PPS (pulses / second) in step S2, and the motor is driven at 1100 PPS in step S4.

  After sensing that the trailing edge of the cut sheet S has passed through the TOF detector 10 (step S5), the HF motor 40 is further driven for a predetermined step (366 steps at a speed of 1100 PPS) (step S6), and the discharge roller 8 is moved. A command to make the closed position is issued (step S7). Then, the cut sheet S is conveyed until the cut sheet S is detected by the discharge detector 28. During this time, various information is acquired by the scanners 11 and 12 and the MICR 13. When the discharge detector 28 detects that the leading edge of the cut sheet S has reached the position of the discharge detector (step S10), the discharge direction is selected (step S11).

  If there is no reading error of the scanners 11 and 12 or MICR 13 or data defects, the cut sheet S is continued to be conveyed and discharged in the direction of arrow B. In the present embodiment, when the discharge detector 28 detects that the trailing edge of the cut sheet S has passed, it is determined that the discharge has been completed, and a series of processing ends (steps S12 and S13).

  If there is a reading error or data defect of the scanner 11, 12 or MICR 13, first, the HF motor 40 is reversed by a predetermined amount (39 steps), and the cut sheet paper is returned by a minute amount (step S14). Thereafter, the carriage 15 is moved to the CRI position, and the clutch is switched so that the power of the VF motor is transmitted from the vertical drive roller 22 that conveys the roll paper to the validation drive roller 31a (step S16). Thereafter, the roller position of the discharge unit is switched to vertical discharge. That is, the discharge roller 8 is set to the open position, and the vertical discharge roller 31 is set to the closed position (step S17). Then, printing is performed by the print head 14 while conveying the cut sheet S upward (step S18). When the sheet paper S is further conveyed upward (step S19), the cut sheet S is detached from the validation pressing roller 31b and the validation drive roller 31a, and the user can take out the cut sheet S exposed from the upper opening 37. . It is confirmed by the user that the cut sheet S has been taken out by the output of the discharge detector 28 (step S20), whereby the power of the VF motor is transmitted to the vertical drive roller 22 that conveys the roll sheet. The clutch is switched so as to be transmitted, the roller position is returned to the original horizontal discharging position, and a series of processing is completed (S14 to S22).

  According to the present embodiment, for example, when processing a check at a bank counter, the printing apparatus 1 has a U-shaped conveyance path, so that the bank clerk is sitting on a chair and inserting the check as a cut sheet S. And can be easily removed. The printing apparatus 1 automatically discharges the check upward in a different direction from the conventional horizontal conveyance direction when a reading error of the scanner 11, 12 or the CR 13 occurs or a defect in the reading data occurs. Can immediately notice abnormalities and take quick action. In particular, when a plurality of checks are continuously processed, it is very effective because the check in question can be identified without being mixed with other checks by dividing the transport direction according to the reading result.

  Moreover, the following forms can also be considered as an application example of the present embodiment.

  In this application example, regardless of whether a reading error of the detector or a defect in the reading data has occurred, the cut sheet S is always near the position where the leading edge of the cut sheet is detected by the discharge detector 28. Stop the transport. Then, while the conveyance is stopped, the read data is processed or the image read by the scanner is displayed on the display, and the date and signature are checked visually.

  As a result, when there is a problem, the horizontal "first discharge means" is used as it is, and the sheet is discharged without printing. If there is no problem, the vertical “second discharging means” is used, and the paper is endorsed by the print head before discharging.

  According to the above method, it becomes possible to feed back the check reading result and perform the endorsement, and it is possible to prevent a problem that a conventional invalid endorsement is made and a plurality of endorsements are made as a result.

  As described above, in the present embodiment, the discharge direction of the cut sheet S that is a printing medium can be selected according to a predetermined condition. Therefore, the print media can be identified and grouped according to preset conditions. In addition, if another transport device is installed at each discharge port, it is possible to deliver to different places according to certain conditions. For example, if an identification mark is attached to the print medium, it can be easily delivered according to the identification mark.

  Further, according to the present embodiment, for example, when a reading error occurs in the MICR 13 or the scanners 11 and 12 or the read data is defective, it is discharged in the transport direction or in the vertical direction. It is characterized in that it can be discharged or selected according to the conditions. Therefore, only problematic print media can be discharged to different discharge ports so that they can be easily identified.

  In particular, when the print medium is continuously flowed, if the print medium is discharged to the same discharge port, normal ones and problematic ones are mixed, and it is very difficult to sort them later. Therefore, in such a case, a great effect can be obtained.
