DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device, particularly a printer device for issuing various certificates, which detects the presence or absence of a specific confirmation print and prints the contents of the certificate properly. The present invention relates to a printer device which detects whether or not a certification print has been performed and prints a certification print at a predetermined position based on the detection of the position of the specific confirmation print.

[0002]

2. Description of the Related Art With the development of a copying machine, various mere certificates are easily copied and illegally used. Therefore, when a certificate is issued, various copy protection measures are taken to prevent unauthorized copying of the certificate.

For example, a copy protection method using copy protection paper as a certificate issuance sheet, a method of stamping, a method of preventing copy using a punch, and the like are implemented. I have.

[0004]

The conventional method using copy-protected paper is expensive because of the use of special paper. The method using stamping is easily copied by the rapid development of color copiers. In the method using a drilling machine, a drilling machine must be prepared, so that the cost is also high in this case.

Therefore, the applicant of the present application has proposed a certification content printing printer for printing certification contents on paper, and a certification printer for printing in a specific position a print for proving the certification contents, for example, embossing for emboss printing. And a print printer for the proof are arranged in series, and the print of the proof is printed at a predetermined position on the paper on which the proof is printed by the print printer for the proof, and the emboss print for proving the above proof is printed by the print printer for emboss. We have proposed a certificate automatic issuance device with copy protection.

However, since the certificate issuance device is configured to issue a certificate automatically, a certificate in the form of a blank paper due to toner exhaustion, double feed, or the like is generated at the stage of the certification content printing printer. Issued,
In addition, the emboss print for content proof is printed with the position shifted from the proof content print because the print is supplied to the emboss print printer in a shifted state, and a situation that does not form a certificate occurs. There is a risk.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and when a certificate is issued, the certificate is printed in a proper format as a certificate, that is, the contents of the certificate are correctly printed, and emboss printing for content certification is performed. It is another object of the present invention to provide a printer device which can issue a certificate which is printed at a regular predetermined position and cannot be easily copied.

[0008]

In order to achieve the above object, a printer according to the present invention exchanges information with a host computer in accordance with the contents of issuance of a designated certificate, and automatically exchanges the designated certificate. In a printer device that issues a certificate, a certification content printing printer that prints the certification content of a specified certificate on paper, and the certification content is certified at a predetermined position with respect to the printing of the certification content printed by the certification content printing printer A certification printer for printing a certification print for
A paper transport unit for transporting the paper, a sensor provided on a print head of the certification printer, for reading a specific print printed by the certification content printing printer, and a control unit for controlling each of the above devices; When the above-described specific print to be printed by the print printer is detected, the certifying printer performs certifying printing and issues a proper certificate.

A print position determining unit that compares a read position read by the sensor with an original position of the read position on a sheet and determines whether the read position is printed within an allowable range; A print position correction unit that corrects a print position at which the certification printer prints based on a sensor reading position and an original position on the sheet when the print position determination unit determines a position shift outside the allowable range; When the certification printer performs certification printing, it is configured to correct the misregistration of the printing of the certification contents on paper and issue a regular certificate.

As the above-mentioned certification printer, for example, an emboss printing printer or the like that performs certification printing by emboss printing that cannot be copied substantially is used.

[0011]

[Function] If the specific print printed by the certification content printing printer cannot be read by the sensor provided in the print head of the certification printer, the certification content is regarded as not being properly printed, and the certification printer performs emboss printing. No, the paper is discarded.

Further, when a specific print printed by the certification content printing printer is detected within an allowable range, emboss printing is performed at a predetermined position on the paper, but when the specific print is detected outside the allowable range, The printing position for printing by the embossing printing printer is corrected, the embossed printing of the certification printing is printed at a predetermined position with respect to the printing of the certification contents, and a proper certificate is issued.

The printing performed by the printing printer for embossing includes not only characters but also figures, for example, academic emblems and company emblems.

[0014]

FIG. 1 is an overall schematic explanatory view of one embodiment of a printer device according to the present invention. In the figure, a certification content printing printer for printing certification contents, for example, a laser beam printer 2, and paper printed by the laser beam printer 2 are provided on the outer surface of the case body 1 inside a case body 1. Paper transporting means 4 for transporting to the position of the shutter 3; an embossing print printer 5 for certifying in a concave and convex form in order to certify the print content printed by the laser beam printer 2 in the middle of the paper transporting means 4; An ID card reading unit 6 for reading a card; an input unit 7 for inputting a personal identification number or a desired type of a certificate; a display unit 8 for displaying an operation method of the apparatus and certificate options; a fee for issuing a certificate; A money transfer unit 9 for transferring money, a communication unit 10 for communicating with a host computer managing a certificate database, and managing control of a series of operations of each device. Control unit 11 and the like.

The operation of issuing a certificate is briefly described as follows. When issuance of a certain certificate is designated from the input unit 7, communication with the host computer is performed via the communication unit 10, and data necessary for issuing the certificate is transmitted and received. The printed paper with the certificate is ejected.

The sheet is composed of two guide plates 12-1 and 12-1.
-2. Sensor 13-
When 1 detects the leading edge of the paper, the drive guide roller 14 of the paper transport means 4 is driven by the paper transport motor 15 and driven at the same speed as the paper feed speed of the laser beam printer 2. When the sensor 13-1 detects the trailing edge of the sheet, the sheet feed control is performed regardless of the sheet feed speed of the laser beam printer 2.

The printer 13 for embossing is provided with a sensor 13-2 for detecting the leading end of the sheet and one of the left end and the right end, respectively.
By the paper position detection of -2, the paper feed control for performing the emboss print for the certification at the predetermined position according to the predetermined model of the certificate designated from the input unit 7 is performed.

In the embossing print printer 5, FIG.
As described below, the embossed printing printer is configured to detect whether or not the paper printed by the laser beam printer 2 has a blank paper printing state due to, for example, running out of toner or double feed. It is also determined whether the print position of the certification content printed on the paper to be input to the printer 5 has been shifted or not. If the former blank paper print state is detected, the reject stacker 19 is detected. When the deviation of the printing position of the certification content on the paper is detected, the printing position of the emboss printing is corrected, and then the emboss printing for certification is printed. How to detect the printing state of the blank paper, the detection of the printing position shift, and the correction of the emboss printing will be described later in detail.

The paper on which the certification emboss print of a predetermined type has been made on the paper by the embossing print printer 5, ie, the regular certificate, is fed, and the guide plates 12-4 and 12-4 are fed.
-5 and is stored in the temporary stack section 16 formed by the と.

When such a series of processes is repeated and the number of certificates designated by the input unit 7 is stored in the temporary stack unit 16, the solenoid 17-1 moves the guide plate 12-4 to the guide plate 12-5. Push up to the side. Guide plates 12-4 and 1
A predetermined number of certificates held between 2-5 are conveyed toward a shutter 3 provided on the outer surface of the case body 1. The shutter 3 is opened each time the solenoid 17-1 pushes up the guide plate 12-4 toward the guide plate 12-5.

Therefore, the certificates are conveyed until the leading ends of the predetermined number of certificates slightly protrude from the shutter 3. At this time, the sensor 13-3 detects the conveyance of the certificate. A predetermined number of certificates conveyed to the shutter 3 are taken out of the shutter 3.

On the other hand, if the certificate remains at the shutter 3 even after a lapse of a predetermined time from the detection of the transport of the certificate by the sensor 13-3, the solenoid 17-2 operates and the guide plate 12-7 is moved. The press-down passage is switched below the guide plate 12-4. Then, the drive guide roller 14 of the sheet conveying means 4 rotates in the reverse direction, and the certificate remaining at the shutter 3 is reversely conveyed.

As described above, since the guide plate 12-7 is pushed down below the guide plate 12-4, the certificate conveyed in the reverse direction passes between the guide plates 12-6 and 12-7. The sheet is conveyed to the reject stacker 19 after changing the conveyance path. At this time, the sensor 13-4 detects that the certificate is conveyed to the reject stacker 19, and based on this detection, data relating to the certificate is stored in the memory of the control unit 11.

FIG. 2 is a schematic view of a print head of an embossing print printer. In FIG.
A printing head 23 for embossing is attached to the belt 22 driven by the motor 21, and the printing head 23 for embossing can be freely moved left and right by rotation of a motor 21.

The print head 23 for embossing is provided with, for example, a reflection type sensor 24 so as to read characters, figures and the like printed on paper. FIG. 3 shows a bottom view of an embossing print head according to an embodiment, in which pins 25 capable of moving up and down are provided.

Since the pin 25 presses the paper in a needle shape in accordance with a predetermined printing type, emboss printing, that is, printing of characters and figures having irregularities on the paper, is performed. Since the embossed portion of the certificate cannot be copied, it is virtually impossible to copy the certificate.

By the way, depending on the type of the certificate, a type having a ruled line at the head position of the certificate as shown in FIG.
In addition, as shown in FIG. 5, the certificate is classified into a type in which the leading position of the certificate is blank, and a type in which the leading position of the certificate shown in FIG. The laser beam printer 2 prints the mark, for example, a check mark such as a cross, so that the mark is not visible.

The reflection type sensor 24 shown in FIGS. 2 and 3 is a part of the above-described specific printing, that is, a part of the above-mentioned ruled line shown by a square 31 in FIG. 4 or a cross shown by a dotted line in FIG. The presence or absence of the confirmation mark and its position are detected. Based on a part of the ruled line or the presence or absence of the confirmation mark, the laser beam printer 2 detects whether the certification content is properly printed, that is, whether or not the toner is out of toner or a blank print due to double feed or the like. From the detection of the position of the part or the confirmation mark, whether the print of the certification content is not supplied to the emboss print printer 5 in a state shifted from the regular print position, that is, the emboss print printer 5
When the embossed printing is performed, the proof printing is performed at a predetermined position in accordance with the predetermined model of the certificate, and it is detected whether or not the appearance as a regular certificate can be held.

As a result of detecting the position of a part of the ruled line or the confirmation mark, if the detected position is out of the allowable range, the print position is corrected at the time of emboss printing by the emboss print printer 5, and the laser beam printer 2 The embossed printing is performed at a predetermined position with respect to the printing of the certificate content printed in the above-mentioned manner, and a regular certificate in a style is issued.

FIG. 6 shows an embodiment of a control section for processing the position information detected by the reflection type sensor. In the figure, reference numerals 5, 10, and 11 correspond to those in FIG. 1, and reference numerals 23 and 24 correspond to those in FIGS. Reference numeral 26 denotes a memory, 27 denotes a print position determination unit, and 28 denotes a print position correction unit.

The memory 26 stores the certificate contents and the certificate print information designated by the information exchange of the host computer via the communication unit 10, and stores the information of the certificate contents through another means (not shown). Is sent to the laser beam printer 2.

The print position discriminator 27 prints a specific print of the certificate, for example, "" in the ruled line at the upper left of the paper in the case of the certificate of FIG. The position information of the “+” mark of the confirmation mark is compared with the position information of these specific prints detected by the reflective sensor 24 and sent to the laser beam printer 2. When the position information is out of the predetermined allowable range in the comparison of the position information, correction information indicating the amount of the position error is output. When the reflection type sensor 24 cannot detect the specific printing, the abnormal information is output as a blank printed matter.

The print position correction unit 28 is provided with a print position determination unit 2
7, when the correction information indicating the misregistration amount out of the permissible range output from the memory 26 is received, the correction information is added to the position information on the emboss print for certification read from the memory 26 to generate new position information. Then, the corrected emboss print position information is sent to the emboss print printer 5.

The manner in which the position information detected by the reflection sensor 24 is processed in the control unit 11 can be determined in the case of detecting the presence or absence of a specific print and the case in which the specific print is detected and the positional deviation amount is out of an allowable range. This will be described separately below.

FIG. 7 shows an embodiment of the detection of the presence / absence of a specific print.
The flowchart is shown. The specific printing is, for example, FIG.
"" Enclosed by a square 31 of the upper left ruled line will be described as an example.
From the memory 26, the ruled line ""

The print information detected by the reflection type sensor 24 is compared with the position information (X _P , Y _P ) already stored in the print position discriminating section 27, and if there is a ruled line “” of a specific print. When the determination is made, a signal indicating no print position correction is sent from the print position determination unit 27 to the print position correction unit 28. Based on this, the emboss print information read from the memory 26 is corrected in position by the print position correction unit 28. The print is sent to the embossing print printer 5 without being printed, and the emboss print for certification is printed at a predetermined position on the paper 30 (step 6).

If the reflection type sensor 24 cannot detect the print information even when the vicinity of the position information (X _P , Y _P ) stored in the print position determination section 27 is scanned (step 5), the designated certification The print position discriminating unit 27 outputs the abnormal information as what is not printed by the laser beam printer 2, that is, as a blank printed matter, and the control unit 11 stops the certification printing to the emboss print printer 5,
The occurrence of an abnormality is notified to the host computer via the communication unit 10 (step 7).

When the position information of the ruled line "" of a specific print detected by the reflection type sensor 24 is determined to be outside the predetermined allowable range by the print position determining unit 27, the print position correction described below will be performed. After processing, the laser beam printer 2
The embossed print for proof is given at a predetermined position with respect to the print of the proof content printed in the above, and a regular certificate in a style is issued.

For a specific print, for example, on a sheet of paper with a check mark "+" indicated by a dotted line as shown in FIG. 5, the method of correcting the print position of the emboss print is shown in FIG. The printing position correction will be described with reference to a flowchart of one embodiment.

The detection of the presence / absence of printing of the confirmation mark "+" indicated by the upper left dotted line shown in FIG. 5 is executed through the procedure described in the flowchart of FIG. 7 (step 11). When the print position of the check mark “+” is detected within the allowable range and when the print of the check mark “+” is not detected, the processing according to FIG. 7 is performed. When the print position determination unit 27 determines that the print position of the mark “+” is out of the allowable range, the print position determination unit 27 determines the shift amount of the mark “+” from the upper left end of the paper 30 as a base point.
_{× = X P -X 0, △} Y = calculates the Y _P -Y ₀ (step 12), printing deviation amount print position from the origin of the paper 30 in the "+" (△ X, △ Y) obtained.

The print position discriminating section 27 sends the shift information ($ X, $ Y) to the print position correction section 28 and prints the emboss print information (X _E , Y _E ) read from the memory 26 with the print position. Correction (X _E + △ X, Y _E + △ Y) is executed by the print position correction unit 28 (step 13), and the new corrected emboss print position information (X ₁ , Y ₁ ) is output to the print position correction unit. 28 to the emboss print printer 5. Here, X ₁ = X _E + △ X, Y ₁ = Y _E + △ Y.

Since the emboss printing printer 5 performs emboss printing based on the corrected emboss printing position information (X ₁ , Y ₁ ), the emboss printing is performed on the certification contents printed by the laser beam printer 2 in advance. An emboss print for proof is printed at the position (step 14), and a well-formed regular invention certificate is issued.

Although the description has been given of the case where the confirmation mark of "+" is printed on the paper 30 as the specific printing, the confirmation mark as the specific printing is simultaneously printed in the X and Y directions of the paper 30 respectively. Any symbol can be used as long as it can be distinguished.

In the above description, the embossing printing printer 5 has been described as an example of the proof printing. However, other proof printing, for example, a stamp may be imprinted. Even if the certification content is printed out of the original print position, the certification stamp can be pressed at a predetermined position corresponding to the printing of the print content.

[0046]

As described above, according to the present invention, issuance of a certificate of a defect in a certification content printing printer can be avoided, and even if the certification content is printed at a shifted position, the certificate content is set at a position corresponding to the deviation. The certification print is printed, and the designated official certificate can be automatically issued.
