Description

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

2. Description of the Related Art In recent years, automatic deposit machines, for example, have been developed and put into practical use as banks become more labor-saving.

Such automatic deposit machines are generally equipped with a printing device that automatically prints transaction details on a bankbook brought by a user. Therefore, in this type of printing device, when printing, it is necessary to determine whether or not there is a printed line on the printing surface of the passbook and to specify the line to be printed, that is, the printing position. However, the method of specifying the print position in the secondary column is to print optical marks in advance on the print surface of the passbook corresponding to each print line, and then use a light source that irradiates the print surface with a narrow spot light and its reflected light. The line mark is detected by spot-scanning the printed surface of the inserted passbook parallel to the conveyance direction using the receiving light-receiving element, and the output of the light-receiving element is integrated between the detection signals, and the output voltage is used to detect the printing. By detecting the presence or absence, it is determined whether there is a printed line or not, and based on the determination result, the printing position is designated and the printing operation is started. However, with these conventional methods, the printing surface is spot-scanned with a narrow field of view, so it is not possible to detect the presence or absence of printing accurately unless there is a high density of printing, which makes it difficult to accurately determine the presence or absence of printed lines. Not only is this not possible, but if there is a small dirt on the printing surface of the passbook, the printer may mistake it for printing and print by skipping lines. Further, even if printing is performed across lines, it is not possible to accurately determine whether or not there are already printed lines. Furthermore, it cannot be detected unless it is printed in a certain position. Therefore, the printing position may be restricted. In addition, line marks are printed on the printing surface, and the presence or absence of printing is detected based on the detection signal of the line marks, so this method cannot be used for passbooks without line marks. Another problem was that it lacked versatility. The present invention has been made in view of the above circumstances, and its purpose is to obtain high accuracy in detecting the presence or absence of printing without being restricted by printing density, printing condition, printing position, etc., and to detect the presence or absence of printed lines. The present invention aims to provide a passbook printing device that can reliably determine the next printing position and always accurately specify the printing position so that it is next to the last printed line of the entire printing surface to be printed next. .

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows, for example, a deposit passbook P printed by the printing device of the present invention with its predetermined pages opened. In the darkness between the front cover 1 and the back cover 2, a plurality of pages 3 are bound in booklet form. There are multiple lines (tana') on each printing surface of these page 3.
24 printing lines 4 are provided.

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, for example, an automatic teller machine in which the printing device of the present invention is used. A substantially L-shaped operating section 6 is formed on the front surface of the weight body 5, and the operating section 6 is vertically On the surface there are a card insertion slot 7 into which a personal identification card is inserted, a bankbook insertion slot 8 into which the above-mentioned bankbook P shown in FIG.
, and a banknote return slot 10 are provided, respectively.
Also, on the horizontal surface is a deposit slot 11 into which banknotes to be deposited are inserted.
, amount display section 12 that displays the deposit amount, deposit approval key 1
3 and a deposit non-approval key 14 are provided.

The crab body 5 corresponding to the passbook insertion slot 8 houses the passbook printing device of the present invention, for example, the third passbook printing device.
It is configured as shown in the figure.

In other words, 21 is the passbook guide frame, which is the passbook insertion slot 8.
The passbook P inserted from the passbook insertion slot 8 in an open state in the direction of the arrow shown in the figure is guided horizontally. 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 conveying section 26, which conveys and takes in the passbook P while holding the passbook 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. The passbook P transported by the transport section 26 is transferred between a platen roller 27 and a tension roller 28 provided at the terminal end of the transport section 26, and is pinched and transported by these rollers 27 and 28. The rollers 27 and 28 are driven by the pulse motor 25. For example, a wire dot type print head 29 is provided above the platen roller 27. This print head 29 has a support base 30 that slides along a rod 34 by a pulse motor 31, a wire 32, and a pulley 33. By being driven dynamically, dots of predetermined data are printed on the printing surface of the passbook P for each line. In the figure, 35 is an ink ribbon, and 36 is an ink ribbon cassette. on the other hand,
A first detector 37 for optically detecting the trailing edge of the passbook P to be transported is provided near the starting end of the front transport path 26 constituting the transport section 26. 37 is composed of a light source 37 and a light receiving element 372 that receives light from the light source 37.

Further, a second detector 38 is provided approximately halfway along the front conveyance path 26, and optically detects the trailing edge of the passbook P that is also conveyed. a light source 38 and a light receiving element 3 that receives light from the light source 38
82. 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 column, and performs photoelectric conversion. That is, the photoelectric conversion 41 optically scans a predetermined area (for example, the date printing column) of the printed surface of the passbook P for each line as it is transported, and performs photoelectric conversion. 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 arranged perpendicular to the conveyance of the bankbook P. In addition, the above light army conversion 4
The distance between the center of the photoelectric converter 41 and the center of the first detector 37 is approximately equal to 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. center and second
The distance 2 from the center of the detector 38 is approximately equal to the distance between the upper edge of the 13th line of the printing surface of the bankbook P and the rear edge of the bankbook P.

That is, the first detector 37 detects the trailing edge of the passbook P when the top edge of the first line of the printing 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 top of the first line of the printed surface is positioned. Set up relationships.
FIG. 5 shows a print position designation control circuit for the position 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 supplied to a level comparison section 52. be done.

This level comparison section 52 slices the output signal of the analog processing section 51 at a predetermined level for each scanning line, and slices the output signal of the analog processing section 51 into black, black,
This is a circuit that quantizes to white level. On the other hand, the outputs of the first and second detectors 37 and 38 are supplied to a pseudo row signal generating section 53. The pseudo row 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, when the first detector 37 detects the trailing edge of the passbook P, the detection signal is used as the row signal for the first row, and the subsequent row signals from the second row to the 12i-th stroke are 1 After the detector 37 detects the trailing edge of the passbook P, for example, by counting the driving pulses of the pulse motor 25, it sequentially outputs a pseudo line signal for each predetermined number of pulses corresponding to the line pitch on the printing surface. do. Similarly, when the second detector 38 detects the trailing edge of the passbook P,
The detection signal is used as the 13th row signal, and the subsequent row signals from the 1st to the 2nd row signal are sequentially generated as pseudo row signals for each specified number of pulses by counting the pulses mentioned above. Output. 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 printing presence/absence detecting section 54 together with the output signal of the level comparing section 52.

This printing presence/absence detection section 54 counts the bits that have been converted into black level and determined to be black level by the level comparison section 52, for example, for each scanning line until the next row signal is output, and the total number of these counts is a set value. This circuit detects the presence or absence of printing in each printing line by determining that there is printing when the number is above, and that there is no printing when it is less than that. Note that the above setting values are appropriately set depending on the size of the printed text 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 a character has a high printing density, it will be determined that there is printing on the next line if it spans about 1 to 2 lines, and if it is a character with a low printing density, it will not be determined that there is printing unless several lines are scanned. Don't judge. Therefore, each time one line is scanned, it is determined whether there is printing or not, and after taking a margin such as back printing, for example, the line determined to be 2 lines white 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 64 is supplied together with the line signal output from the pseudo line signal generation section 53 to the latest printed line number storage section 55 and the printed line number storage section 56, respectively. .

The line number storage unit 55 counts the line signals, for example, and when the print presence detection unit 54 outputs a print presence signal, stores the count contents at that time, and thereafter stores the stored contents when the print presence signal is input. This is a circuit that detects the latest (that is, final) number of printed lines by updating it every time the line is printed. Further, the printed line number storage section 56 is a circuit that stores the number of printed lines by counting, for example, an AND signal of the line signal and the print presence signal. Further, the row signal output from the pseudo row signal generating section 53 is supplied to the all row scanning end determining section 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 all-line scanning end determination section 57 is transmitted to the line number storage section 55 and the printed line number storage section 56.
are supplied to the print position determining section 58 along with each output. For example, when an all-line scanning end signal is output from the all-line scanning end determining section 57, the print position determining section 58 determines the position based on the contents of the line number storage section 55 and the printed line number storage section 56 at that time. The line to be printed, that is, the printing position, is determined by determining the continuity of the printed lines from the first line, and the determination signal is supplied to the printing position specifying section 59. Furthermore, when the print position determination section 58 determines that the printed lines are not consecutive, it sends a signal to that effect to the alarm 60, thereby notifying the staff through the alarm 60. ing. The print position specifying section 59 supplies a specified number of pulses corresponding to the print position determined by the print position determining section 58 to the pulse motor 25, so that the determined print position is in the opposite direction to the print head 29. This circuit designates the printing position by conveying the passbook P until it is stopped and then stopping the passbook P. As a result, the line next to the last printed line of the entire print surface comes to stop facing the print head 29. Next, the operation in the configuration as described above will be explained.

For example, when a user inserts his or her own bankbook P into the bankbook insertion slot 8 in the direction of the arrow shown in FIG. and,
When the tip of the passbook P is detected by the detector 22, the solenoid 23 is operated and the shirt cover 24 is opened.
The pulse motor 25 operates to drive the conveyance section 26, and the inserted passbook P is conveyed by the conveyance path 26, taken inside, and conveyed toward the print head 29. After that, when the first detector 37 detects the trailing edge of the passbook P, the detection signal is used as the row signal for the first row as described above, and the subsequent rows from the second row to the 12th row are The signal is output from the pseudo row signal generator 53 separately. Similarly, the second
When the detector 38 detects the rear edge of the passbook P, the detection signal is used as the 13th row signal as described above, and the subsequent row signals from the 14th row to the 24th row generate pseudo row signals. The information is sequentially output from the section 53. When the row signal of the first row is output, that row signal is used as the scanning start signal of the photoelectric converter 41, and at this time, the photoelectric converter 41 receives the first row of the EO-shaped surface as described above. Since the second date printing column corresponds to the first one, the photoelectric converter 41 scans the date printing column a predetermined number of times from left to right until the next line signal (second line) is output, and performs photoelectric conversion. .

At this time, the output voltage from the photoelectric converter 41 is approximately proportional to the density of the printed surface. The output of this photoelectric converter 41 is passed through an analog processing section 51 to a level comparison section 52.
black, which is then sliced at a predetermined level.
The signal is quantized to a white level and supplied to the print presence/absence detection section 54. As described above, 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, and outputs the result of the detection. It is output to the number storage section 55 and the printed line number storage section 56. The line number storage unit 55 detects the number of printed lines by counting the line signals and storing the count contents when the print presence signal is output from the print presence/absence detection unit 54. On the other hand, the printed line number storage section 56 stores the number of printed lines by counting the AND signal of the line signal and the print presence signal.
The above operation is repeated sequentially for each row after the second row.
In this way, the presence or absence of printing is detected by scanning a predetermined area, that is, the date printing field, with the photoelectric converter 41 between row signals, and the presence or absence of printed lines, that is, printed lines, is determined, and the final At the same time as detecting the number of printed lines, the continuity of the printed lines from the first line among the printing results of the entire printing surface (page) is determined. In this way, the photoelectric converter 41 sequentially scans each row as the passbook P is transported, and when scanning of all rows, that is, the second row is completed, the all-row scanning end determination unit 57 determines that all-row scanning is complete. A signal is output.

As a result, the print position determining unit 58, based on the contents of the line number storage unit 55 and the printed line number storage unit 56 at this time,
The printing position is determined by determining the continuity of the printed lines from the first line. For example, if the content of the line number storage unit 55 is "5",
If the content of the printed line number storage unit 56 is also "5", since they match, it is determined that the first to fifth lines are consecutively printed lines. Also, the contents of the line number storage unit 56 are “
5'', this means 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. However, at this time, the number of printed lines storage section 56
For example, if the content is "3", it does not match the content "5" of the line number storage unit 55, so in this case it is determined that the printed lines are not consecutive, and the alarm 60 is activated with the determination signal. This notifies the staff that the print position cannot be determined, that is, that there is an abnormality. When the print position is determined as described above, the print position specifying unit 59 supplies the pulse motor 25 with a prescribed number of pulses corresponding to the determined print position, that is, the line to be printed, and The passbook P is conveyed and stopped until the printing position corresponds to the print head 29.

As a result, the next line after the last printed line, for example, the sixth line in the above example, stops facing the print head 29.
In this way, based on the results of scanning the entire printing surface, that is, all lines from the first line to the second line, the last printed line of the entire printing surface, that is, the last line of consecutive printed lines, is selected. By detecting this, the printing position is designated. Here, the print head 29 operates by combining the print command and predetermined print data from the control unit of the automatic deposit device, and for example, the date, deposit amount, balance, etc. are displayed in each of the print fields. It is printed. When printing is completed, the passbook P is returned to the insertion slot 8 by rotating the pulse motor 25 in the reverse direction. As explained above, according to the above embodiment, for example, a self-scanning line array having high resolution and a wide field of view is used as a photoelectric converter, and this photoelectric converter scans the entire printed surface of the passbook line by line. By scanning a predetermined area (date printing column), the presence or absence of printing is detected and the presence or absence of a printed line is determined, so the detection condition is relaxed so that it is only necessary that there is printing within a wide field of view. Even with low-density printing, printing that spans between lines, or even if the position of the printed characters is not constant, it is possible to obtain printing accuracy and detect the presence or absence of printed lines without being restricted by these conditions. This can be determined reliably, and the printing position can always be accurately specified, such that the next line to be printed is the one next to the last printed line on the entire EO font.

Moreover, since the continuity of printed lines is also determined, if there is a line skip in the already printed lines, this can be detected as an abnormality. In addition, since the presence or absence of printing is detected based on the black and white levels of each scanning line and the presence or absence of a printed line is determined, for example, if the line is misaligned up or down, the skip criterion may depend on the printed character. There is no variation, and more accurate judgments can always be made.

Furthermore, pseudo-line signals are sequentially generated based on the edge detection signal of the bankbook being conveyed, and the presence or absence of printing is detected based on this pseudo-line signal. This provides an extremely convenient and versatile printing device. In the embodiment described above, only the date printing column of each line was scanned to detect the presence or absence of printing, but for example, only the balance printing column or the entire line may be scanned.

Further, although the printed surface is sequentially scanned line by line starting from the first line, for example, the insertion direction of the passbook may be reversed and the printed surface is 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, but one detector was used to detect the trailing edge of the passbook. A pseudo row signal may be generated based on the detection signal. Furthermore, in the above embodiment, pseudo line signals are sequentially generated based on the passbook edge detection signal, and the presence or absence of printing is detected based on these pseudo line signals. A mark may be printed in advance, and the presence or absence of printing may be detected according to the present invention based on the detection signal of this line mark.

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. The same can be applied to a printing device that automatically prints. 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 detailed above, according to the present invention, the presence or absence of printing is determined and stored in advance by scanning a predetermined area with light for each line of the printed surface of a passbook, and based on the determination result, whether the printed lines are continuous or not. Based on the results of both judgments, the printing position is determined so that the next printing is performed on the line following the last line of the line judged to be continuous by the printed line continuity judgment means. Since this is specified, the presence or absence of printing can be detected accurately without being restricted by printing density, printing condition, printing position, etc., and the presence or absence of a printed line can be reliably determined, and the next line to be printed can be determined. It is possible to provide a passbook printing device that provides various effects such as being able to always accurately specify the printing position so that it is placed next to the last printed line on the entire printing surface.
