Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a form printing device that automatically prints transaction details on a bankbook in, for example, an automatic deposit machine.

2. Description of the Related Art Recently, various automatic deposit machines, for example, have been developed and put into practical use with the effort to save labor in banking operations.

Such automatic deposit machines are generally equipped with a printing device that automatically prints transaction details on a bankbook brought by a user. However, since automatic deposit machines are generally operated by the user alone without the intervention of bank staff, if the user does not fully understand the functions of the automatic deposit machine,
Various problems arise. For example, if the ink ribbon of the printing device breaks, the ink ribbon is not set correctly, the ink density of the ink ribbon falls below the specified value, or a problem with another printing device causes the printing device to stop printing. However, if the passbook is not printed at all, or if it is printed but not in the correct position due to poor transportation of the passbook, the passbook may not be returned to the user as is. , there was a risk that the user would not notice this and leave the transaction thinking that the transaction had ended normally. Although some general printing devices have a function to detect whether or not the ink ribbon is set correctly, these devices cannot detect whether the ink ribbon has been printed on the print medium or not. However, the system was not fully reliable as a device used by ordinary people such as bank users.

The present invention was made in view of the above circumstances, and its purpose is to quickly detect when some kind of failure occurs and the documents are not printed correctly, so that the staff can take appropriate measures. The present invention aims to provide a form neck printing device that is capable of highly reliable and accurate printing. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows, for example, a bankbook P printed by the printing device according to the present invention with its predetermined pages opened, and between the front cover 1 and the back cover 2 there are a plurality of pages 3
are bound in booklet form, and each printing surface of these pages 3 is provided with a plurality of (for example, 24) printing lines 4.

Each of these printing lines 4 is provided with a date printing field, a deposit amount printing field, a payment amount printing field, a balance printing field, and the like. FIG. 2 schematically shows the external appearance of, for example, an automatic teller machine in which the printing device according to the present invention is used, in which a substantially L-shaped operating section 6 is formed on the front surface of the armor body 5.
On the vertical surface of this operating section 6 are a card insertion slot 7 into which a personal identification card is inserted, a bankbook insertion slot 8 into which the bankbook P shown in FIG. 9, a banknote return slot 10, etc. are provided respectively, and the horizontal surface has a deposit row 1 for inserting banknotes to be deposited, an amount display section 12 for displaying the deposited amount, a deposit approval key 13, and a deposit non-approval key. A key 14 and the like are provided.

Therefore, in the cliff body 5 corresponding to the passbook insertion slot 8,
A form printing device according to the present invention is housed therein, and is configured as shown in FIG. 3, for example.

In other words, 21 is the passbook guide frame, which is the passbook insertion slot 8.
The passbook P is inserted through the passbook insertion slot 8 in an open state and horizontally guided in the direction of the arrow shown in the figure. When the passbook P is inserted into the guide frame 21, the tip of the passbook P is detected by the optical detector 22, and the solenoid 23 is operated to open the shutter plate 24, and the pulse motor 25 is operated to drive the conveyance path 26, and the conveyance path 26 conveys and takes in the passbook P while holding the bankbook P at its substantially central portion. The conveyance path 26 is composed of a front conveyance path 26 and a rear conveyance path 262, which are provided in series, as shown in FIG. 4, for example, and is driven by the pulse motor 25. Thus, the passbook P conveyed by the conveyance section 26 is transferred between the platen roller 27 and the tension roller 28 provided at the end of the conveyance path 26, and the passbook P is transferred between the platen roller 27 and the tension roller 28 provided at the end of the conveyance path 26. Each of the loaves 27 and 28 is driven by the pulse motor 25. A wire dot type print head 29 is provided above the platen roller 27, for example. This print head 29 prints dots of predetermined data for each line on the print image of the passbook P by driving its support base 30 along a rod 34 by a pulse motor 31, a wire 32, and a pulley 33. It looks like this. In the figure, 35 is an ink ribbon, and 36 is an ink ribbon cassette. on the other hand,
As shown in FIG. 4, a first detector 37 for optically detecting the trailing edge of the passbook P being transported is provided near the starting end of the front transport path 26 that constitutes the transport path 26. This first detector 37 has a light source 37, and this light source 37,
The light receiving element 372 receives light from the light receiving element 372.

Further, a second detector 38 is provided approximately halfway through the front conveyance path 26, and optically detects the trailing edge of the passbook P, which is also conveyed. 38, and a light receiving element 38 that receives light from this light source 38.
It consists of 2. Furthermore, the above-mentioned front stage conveyance path 26. A light source 39 is provided near the end of the passbook P that irradiates light onto a predetermined portion of the printed surface of the passbook P that is being conveyed, such as the date printing column of the printing line 4. A photoelectric converter 41 is provided which receives light through an optical system 40, scans the date printing field, and performs photoelectric conversion. That is, the photoelectric converter 41
As the passbook P is conveyed, the printed surface of the passbook P is optically scanned for each line over a predetermined area (for example, the date printing column) and photoelectrically converted. The photoelectric converter 41 is, for example, a so-called self-scanning line array formed by linearly arranging a large number of solid-state image sensors (image sensors), and is disposed perpendicular to the direction in which the passbook P is conveyed. Note that the distance 1 between the center of the photoelectric converter 41 and the center of the first detector 37 is
, is roughly the distance between the top edge of the first line of the printing surface of the bankbook P and the rear edge of the bankbook P, and the distance 12 between the center of the photoelectric converter 41 and the center of the second detector 38 is , is approximately equal to the distance between the upper edge of the 13th line of the printing surface of the bankbook P and the trailing edge of the bankbook P.

In other words, the first detector 37 detects the trailing edge of the passbook P when the top edge of the first line of the printed surface is located approximately at the center of the photoelectric converter 41; The first and second detectors 37 and 38 and the photoelectric converter 41 are arranged so that the second detector 38 detects the trailing edge of the passbook P when the upper edge of the printed surface is located at the 13th edge of the printing surface. 5 shows a control circuit of a printing device configured as described above, in which the output of the photoelectric converter 41 is subjected to analog processing in an analog processing section 51 and then sent to a level comparison section 52.
supplied to This level comparison section 52 is a circuit that slices the output signal of the analog processing section 51 at a predetermined level for each scanning line and quantizes it into black and white levels. on the other hand,
The outputs of the first and second detectors 37 and 38 are supplied to a pseudo row signal generator 53. The pseudo signal generating section 53 is a circuit that sequentially generates pseudo row signals according to the outputs of the first and second detectors 37 and 38. That is, the first detector 37
When detects the trailing edge of the passbook P, the detection signal is used as the line signal for the first line, and the subsequent line signals for the second to twelfth lines are determined by the first detector 37 as the line signal of the passbook P. After detecting the trailing edge, for example, by counting the driving pulses of the pulse motor 25, a pseudo line signal is sequentially outputted every predetermined number of pulses corresponding to the line pitch on the printing surface. Similarly, when the second detector 38 detects the trailing edge of the passbook P, the detection signal is used as the row signal for the 1st line, and the subsequent row signals for the 1st to 24th lines are as follows: By counting the pulses, a pseudo row signal is sequentially outputted every prescribed number of pulses. Therefore, for example, a pseudo line signal is output at a position corresponding to a line mark conventionally printed on the printing surface. The row signal output from the pseudo row signal generating section 53 is supplied to the print presence/absence detector 54 together with the output signal of the level comparing section 52.

The print presence/absence detection unit 54 counts the bits that have been converted into ink and determined to be black level by the level comparison unit 52, for example, for each scanning line until the next line signal is output, and the total number of these counts is set. This circuit detects the presence or absence of printing in each printing line by determining that there is printing when it is greater than the value, and that there is no printing when it is less than that value. Note that the above setting values are appropriately set depending on the size of printed characters and the line pitch. Furthermore, the criteria for determining whether or not to skip when a character is printed with a vertical shift in the line varies to some extent depending on the type of printed character. In other words, if it is a character with a high printing density, it will be determined that there is printing on the next line if the next line is covered by about 1 to 2 lines, and if it is a character with a low printing density, it will be determined that there is printing after scanning several lines. is not judged. Therefore, every time one line is scanned, it is determined whether there is printing or not, and a margin such as Aoi printing is taken, and the line determined to be white, for example, two lines, is determined to be the printing boundary, and a predetermined pulse is calculated from this line and the line signal. Based on the time of conveyance, that is, the mutual position with the center line of the row, it is determined whether the print is on the upper row or the lower row. The output of the printing presence detection section 54 is supplied together with the line signal output from the pseudo line signal generation section 53 to the latest printed line storage section 55 and the printed line continuous storage section 56, respectively.

The latest printed line storage unit 55 counts the line signals, stores the count contents at that time when the print presence signal is output from the print presence/absence detection unit 54, and thereafter uses the stored contents as the print presence signal. This is a circuit that stores the latest (that is, final) number of printed lines by updating it every time the number is input. In addition, the printed line continuous storage section 5
Reference numeral 6 denotes a circuit that sequentially stores whether or not printed lines are consecutive from the first line by counting, for example, an AND signal of the line signal and the print signal. Furthermore, the row signal output from the pseudo row signal generation section 53 is
V is supplied to the full-row scanning end determination unit 57. The all-row scanning end determination section 57 is a circuit that determines whether or not all rows have been scanned by counting the row signals.
Therefore, the output signal of the full-row scanning completion determining section 57 is as follows.
The outputs of the latest printed line marking unit 55 and printed line continuous storage unit 56 are sent to the latest printed line determining unit 58. For example, when an all-line scanning end signal is output from the all-line scanning end determining section 57, the last printed line determining section 58 stores each of the latest printed line storage section 55 and printed line continuous storage section 56 at that time. Based on the content, determine the continuity of the printed lines from the first line to determine the last printed line, and based on the determination result, determine the line to be printed, that is, the printing position,
The determination signal is sent to the print position designation section 59. Further, when the last printed line determination unit 58 determines that there are consecutive printed lines and no printed lines, it sends a signal to that effect to the alarm device 61 via the print control unit 60 to issue an alarm. The device 61 is used to notify the staff. The print position specifying unit 59 supplies the pulse motor 25 with a prescribed number of pulses corresponding to the print position determined by the final printed line determining unit 58, and the determined print position is aligned with the print head 29. This circuit designates the printing position by conveying the passbook P until it faces each other and stopping it. As a result, the line next to the last printed line of the entire print surface comes to stop facing the print head 29. Further, the last printed line determining unit 58 stores the number of the determined last printed line in the last printed line storage unit 62 before printing or in the last printed line storage unit 62 after printing, according to a signal from the printing control unit 60. The data is selectively supplied to section 63 and stored therein.

The last printed line storage section 62 stores the number of the last printed line before printing, which is determined by the last printed line determining section 58. The last printed line storage section 63 stores the number of the last printed line after printing determined by the last printed line determining section 58. Thus, the contents of the last printed line storage section 62 before printing are supplied to the last printed line setting section 65 after printing, together with the contents of the number of printed line storage section 64. The above print line number storage section 6
4 stores the number of print lines supplied from the print control section 60. In addition, after the above printing, the final printed line setting section 6
5 is for calculating and setting the number of lines that must be printed on the passbook after printing is completed, based on the contents of both the storage units 62 and 64. The setting contents of the last printed line setting section 65 after printing are supplied to the comparison section 66 together with the contents of the last EO line after printing storage section 63. This comparison section 66 compares the contents of the storage section 63 with the setting section 6.
5 and the setting contents are compared to see if they match, and the comparison result is supplied to the print control section 6. on the other hand,
Print control section 60' This is the communication control section 67 of the automatic deposit machine.
Transaction data, that is, print data, is supplied from the printer.

The communication control unit 67 is connected online via a modem 68, a communication line 69, and a modem 70 to a central processing unit 71 serving as a deposit ledger, which is installed at a location remote from the automatic deposit machine. In addition, the communication control section 67
is also connected to the deposit control unit 72 of the automatic deposit machine. Thus, the print control unit 6 is connected to the central processing unit 71, the modems 70, 68, the communication line 69, and the communication control unit 6.
The transaction data is transmitted via 7, thereby controlling the printing control unit 6, the print head, the pulse motor 31, etc., thereby printing a predetermined amount on the passbook P. Note that the transaction data sent from the central processing unit 71 is not limited to one bankbook line, but may include unrecorded data for so-called non-bankbook transactions performed without using a bankbook. Printing will be performed over a period of time. The print control unit 6 is configured to store the number of lines printed in the transaction in the print line number storage unit 64 in this way. Next, the operation in the above configuration will be explained. For example, when a user inserts his or her bankbook P into the insertion slot 8 in the direction of the arrow shown in FIG. When the tip of the passbook P is detected by the detector 22, the print control unit 60 operates the solenoid 23 to open the shirt flap plate 24, and operates the pulse motor 25 to open the conveyance path 24.
to drive. Therefore, the inserted passbook P is transferred to the transport path 2.
6, the paper is held and conveyed into the interior, and is conveyed toward the print head 29. After that, the first detector 37 detects the passbook P.
When the trailing edge is detected, the detection signal is used as the row signal for the first row as described above, and the subsequent row signals for the second to twelfth rows are sequentially output from the pseudo row signal generator 53. Similarly, when the second detector 38 detects the trailing edge of the passbook P, the detection signal is transmitted to the thirteenth;
The 14th to 24th row signals are sequentially outputted from the pseudo row signal generating section 53. When the row signal of the first row is output, the row signal is used as the scanning start signal of the photoelectric converter 41, and at this time, the photoelectric converter 41
Since the date printing on the row is compatible, the photoelectric converter 4
1 performs photoelectric conversion by scanning the date printing field a predetermined number of times from left to right until the next line signal (second line) is output. At this time, the output voltage from the photoelectric converter 41 is approximately proportional to the density of the printed surface. This photoelectric converter 4
The output of 1 is supplied to the level comparison section 52 via the analog processing section 51, where it is sliced at a predetermined level, quantized into black and white levels, and supplied to the print presence/absence detection section 54. The printing presence/absence detection section 54 detects the presence or absence of printing by counting the bits determined to be black level by the level comparison section 52 until the next line signal is output as described above, and uses the detection result as the latest printing. It is output to the completed line storage section 55 and the printed line continuous storage section 56. The latest printed line storage section 55 counts the line signals and detects the printing presence/absence detection section 5.
When a printing signal is outputted from 4, the count contents at that time are stored, thereby storing the number of printed lines. On the other hand, in the printed line continuous storage section 56, by counting the logical bran signals of the upper trial signal and the printed signal,
It is stored whether the printed lines are continuous or not from the first line. The above operation is repeated sequentially for each row after the second row. In this way, between the row signals, the photoelectric converter 41
The presence or absence of printing is detected by scanning a predetermined area, that is, the date printing field, and the presence or absence of printed lines, that is, the presence or absence of printed lines, is determined, and the number of the last printed lines is memorized. ) This is to determine the continuity of printed lines from the first line of the entire printing result. In this way,
The photoelectric converter 41 sequentially scans each row as the passbook P is transported, and when all rows, that is, the second row has been scanned, an all-row scan end determination unit 57 outputs an all-row scan end signal. . As a result, the last printed line determination unit 58 determines the latest printed line storage unit 55 and printed line continuous storage unit 5 at this time.
6, the continuity of the printed lines from the first line is determined to determine the last printed line, and the printing position is determined based on the determination result. For example, the last printed line storage section 5
If the content of 5 is "5" and the content of the printed line continuous storage section 56 is also "5", then the two match, so the first to fifth lines are
It is determined that the line is printed three times in a row. Also,
Since the content of the latest printed line storage section 55 is "5", it is determined that the last printed line is the fifth line. Based on these, it is determined that the next line to be printed is the line following the last printed line, that is, the sixth line. At this time, if the content of the printed line continuous storage unit 56 is, for example, “3”, it does not match the content of the latest printed line storage unit 55, “5”, so in this case, the printed lines are not consecutive. By combining the determination signal with the print control unit 6, the print control unit 60 activates the alarm 61 to notify the staff that the print position cannot be determined, that is, there is an abnormality. . When the final printed line determining unit 58 determines the final printed line, the final printed line determination unit 58 determines the number of lines (“5” in the above example).
) is supplied to the last printed line storage section 62 before printing and stored therein.

That is, in this case, since printing has not yet begun, the printing end signal is not supplied from the printing control section 60, and therefore, the last printed line determining section 58 stores the judgment result in the last printed line storage section 62 before printing. After being memorized and printed, the final printed line storage section 63
It is designed not to remember anything. Further, when the final printed line determining section 58 determines the printing position, it sends the determination signal to the printing position specifying section 59. As a result, the print position specifying unit 59 sends a specified number of pulses to the pulse motor 2 corresponding to the determined print position, that is, the line to be printed.
5, the passbook P is conveyed until the determined printing position corresponds to the print head 29, and then stopped. therefore,
The line following the last printed line, for example, the sixth line in the above example, stops relative to the print head 29. Transaction data transmitted from the central processing unit 71 is supplied to the print control unit 6, and the print control unit 6 then controls the print head 29 and pulse motor 25 according to the supplied transaction data. 31 is driven and controlled. As a result, the print head 29 and pulse motors 25, 31 operate,
For example, the date, deposit amount, balance, etc. are printed in each of these print columns. At this time, the print control unit 60 stores the number of lines printed at this time in the print line number storage unit 64. In this way, when the predetermined printing is completed, the printing control unit 60' supplies a printing completion signal to the last printed line determination unit 58, and the pulse motor 25 is reversely rotated to P is conveyed in the direction of the insertion port 8.

Thereafter, when the first detector 37 detects the trailing edge of the passbook P, the print control unit 6 rotates the pulse motor 25 in the forward direction again, and the passbook P is again conveyed toward the photoelectric converter 41. . Then, through the same operation as that performed before printing, the last printed line determination section 58 determines the last printed line after printing, and the determination result is stored in the last printed line storage section 63 after printing. be remembered. That is, in this case, since printing has been completed and the printing end signal has been supplied from the printing control section 60, the last printed line determining section 58 stores the judgment result in the last printed line storage section 63 after printing. It is something. In this case, the printing position is not determined.
Only the last printed line is determined. When the last printed line after printing is determined, the last printed line setting section 65 sets the last printed line before printing storage section 6.
By performing a predetermined calculation between the contents of 2 and the contents of the print line number storage section 64, the number of lines that must be printed after printing is set. For example, if the content of the storage unit 62 is “5” and the content of the storage unit 64 is “3”, the last printed line before printing is the 5th line, and the transaction is recorded in the passbook P. This means that the number of printed lines is 3, so after printing, up to the 8th line must be printed. Therefore, the final printed line setting unit 65 after printing performs addition [513] between the content “5J” in the storage unit 62 and the content “3” in the storage unit 64, and the addition result [ 8] is set as the number of final printed lines after printing. The comparing unit 66 compares the contents of the last printed line storage unit 63 after printing and the contents of the last printed line setting unit 65 after printing to see if they match, and transmits the comparison result to the printing control unit. 60. That is, in the above example, the content of the last printed line setting section 65 after printing is "8", and if printing is performed correctly at this time, the content of the last printed line setting section 65 after printing is set to "8".
The content of is also “8”, so the two match, so the match signal is supplied to the print control unit 60. on the other hand,
If the content of the last printed line storage unit 63 after printing is not “8” due to some failure or other reason that printing was not performed correctly, it will not match the content of the last printed line setting unit 65 after printing. Therefore, the comparison section 66 supplies a mismatch signal to the print control section 60'. However, the comparison section 66
When a matching signal is supplied from the print controller 60, the print controller 60 returns the passbook P to its insertion slot 8 by rotating the pulse motor 25 in the reverse direction again. On the other hand, when a discrepancy signal is supplied from the comparing section 66, the printing control section 60 stops all printing operations and activates the alarm 61 to notify the staff of the abnormality. As a result, if the line that should be printed cannot be printed, the bankbook does not have to be returned to the user, and the staff can take appropriate measures. Therefore, it is possible to prevent things that may cause anxiety to the users. In the above embodiment, a case has been described in which the prescribed printing is not performed due to some failure or the like. However, even if there is no failure, for example, the ink density of the ink ribbon has decreased, the level comparison unit 52 By appropriately setting the comparison level, it is also possible to provide a printing density detection function, and thereby it is also possible to automatically notify the staff when it is time to replace the ink IJ cylinder.

Furthermore, if the present invention is applied to automatic deposit machines that use so-called magnetic passbooks with magnetic stripes, which have been used recently,
By recording the number of lines to be printed at one end of the magnetic stripe, the number of lines printed by the print checking method of the present invention matches the number of lines printed within the magnetic stripe, thereby further improving reliability. Excellent printing is possible. Further, in the embodiment described above, only the date printing column of each line is scanned to detect the presence or absence of printing, but for example, only the balance printing column or the entire line may be scanned. Also, set the printing surface to
Although each line is sequentially scanned starting from the last line, for example, the insertion direction of the passbook may be reversed and the printing surface may be sequentially scanned line by line starting from the last line. Further, the photoelectric converter is not limited to a self-scanning line array using a solid-state image sensor, but may also use a photoelectric conversion element having a similar function, or may be an image pickup tube. In addition, two detectors were used to detect the trailing edge of the passbook, and a pseudo line signal was generated based on each detection signal. A pseudo line signal may be generated based on the detection signal.Furthermore, in the embodiment described above, pseudo line signals are sequentially generated based on the passbook edge detection signal, and printing is performed based on this pseudo line signal. Although the presence or absence is detected, line marks may be printed on the printing surface in advance as in the conventional method, and the presence or absence of printing may be detected according to the present invention based on the detection signal of the line marks.

In addition, we have explained the case where it is applied to a printing device that prints transaction details on a deposit passbook in an automatic deposit machine, but it can also be applied to various ledgers, deposit certificates, order slips, order slips, invoices, and other forms. The same can be applied to a printing device that automatically prints predetermined data. In addition, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

As described in detail above, according to the present invention, the presence or absence of printing is detected for each line of a form before printing, the last printed line before printing is determined based on the detection result, and the determination result is In addition to specifying the base printing position and performing the specified printing, the number of printed lines is detected at the time of printing, and the number of printed lines after printing is determined based on the detected number of printed lines and the last printed line before printing based on the above judgment. Set the last printed line, detect the presence or absence of printing for each line of the form after printing, determine the last printed line after printing based on the detection result, and set the final printed line based on the determination result and above. By comparing the last printed line after printing, it is determined whether or not the specified printing was performed correctly after printing. If the ink ribbon is not properly printed, the ink density of the ink ribbon is below the specified value, or some other failure occurs, and the document is not printed correctly despite printing, this can be quickly detected. It is possible to provide a form printing device that can provide various effects such as enabling appropriate treatment by staff and reliable and accurate printing.
