Abstract

PROBLEM TO BE SOLVED: To prevent the leakage of customer information occurring when a content of appropriate transaction is printed across next receipt paper due to print position deviation by a failure or the like of a receipt printer and an inadequate cut position of each roll paper.SOLUTION: A timing mark is positioned and characters are printed, and a cut position is determined by the timing mark. A conveyance amount after printing is checked so that paper is conveyed longer than a distance from a print head to a cutter position. A paper detection mechanism on a conveying path after cutting checks timing when the paper reaches, and a paper length is monitored by the paper detection mechanism so as to prevent short receipt paper which is erroneously cut from being issued, and prevent print from remaining on the next receipt paper. When it is assumed that the print is remained on the next receipt paper, the paper is collected as abnormality and a recovery means such as retry is conducted to prevent the print from remaining on the next receipt paper by printer control.

Description

  The present invention relates to a receipt printer that is mounted on an automatic teller machine used in, for example, a financial institution and prints and issues transaction details.

  Receipt paper of an automatic teller machine (ATM) conventionally used in financial institutions and the like is printed while transporting continuous paper, cut to a length of one sheet, and issued to customers. The receipt paper is pre-printed with bank names, ruled lines, and items. The ruled lines are printed with different contents for each transaction, such as the amount of money and account number, and the transaction details and information are given to the operator. provide.

In recent years, the importance of managing and protecting customer information has increased, and the receipt printer that issues automatic teller machine (ATM) receipts also prints the transaction information of the operator. A function to prevent information leakage is required so that the receipt paper is usually rolled up, and the sensor detects the timing mark printed on each receipt for one sheet. The position and cutting position are determined, information is printed in the above-mentioned ruled lines, and cutting and issuing are performed. However, since there is one timing mark for each sheet, if the position of the timing mark is determined and the transport mechanism is defective or the receipt paper slips or gets stuck, the print position is assumed by the receipt printer. It will be out of position. Depending on the amount and position of deviation, there is a risk of printing across the next receipt sheet. At this time, the portion printed on the next receipt sheet is issued to the next operator, and the information of the previous operator is leaked.

  Conventionally, as this type of apparatus, there is one described in Japanese Patent Application Laid-Open No. 2004-276396 (Patent Document 1).

JP 2004-276396 A

  Since there is one timing mark for each sheet, a shift after the position is determined cannot be detected, and there is a possibility of printing across the next receipt sheet. At this time, the portion printed on the next receipt sheet is issued to the next operator, and the information of the previous operator is leaked.

  If timing marks are provided at a plurality of locations, it is necessary to determine which timing mark is required, and a new sensor and control for separation are required, which is difficult in terms of cost and stability.

  In addition, it has been conventionally performed to check the timing of detecting the timing mark. However, since it is not known whether the position is shifted at a position related to printing, a stricter check than necessary is performed. Since ATM is basically unattended operation, it is necessary to avoid an error stop due to an unnecessary check, and it is difficult to perform a strict check.

  The position is determined by the timing mark and printed, and the cutting position is determined by the timing mark. At this time, by checking that the transport amount after printing is transported more than the distance (distance from the printing part to the cutting part) that does not remain on the remaining cut receipt paper side, The limit check prevents the print from straddling the next sheet.

  In addition, the timing at which the paper arrives is confirmed by the next conveyance path sensor or the like in the conveyance after cutting, and it is confirmed that the printed paper itself is not displaced. These two checks prevent printing from remaining on the next receipt paper regardless of where the slip is.

  In a receipt issuance operation, if the receipt printer prints out of print position due to paper transport failure, it may be printed across the next receipt, or a timing mark may be detected incorrectly, and paper receipt When the paper was cut shorter than the length, printing could remain on the next receipt paper. According to the present invention, it is possible to prevent a portion printed on the next receipt paper from being issued to the next operator.

It is side surface sectional drawing which shows an example of the internal structure of the receipt printer of this invention. It is a figure which shows an example of the pre-printing of the continuous paper used by this invention. It is a figure which shows an example of operation | movement of the receipt printer of this invention. It is a figure which shows an example of operation | movement of the receipt printer of this invention. It is a figure which shows an example of operation | movement of the receipt printer of this invention.

  First, the internal configuration will be described with reference to FIG. 1, which is a side sectional view of a receipt printer as an embodiment of the present invention.

  This receipt printer uses roll-shaped continuous paper 1 and is provided with a paper transport mechanism 2, a timing mark sensor 3 and a print head which are rotated by an actuator (not shown) to transport the paper. A printing mechanism 4 to be performed, a cutter mechanism 5 to cut the paper, a discharge transport mechanism 6 to transport the cut paper, a transport paper sensor 7, and a paper discharge port 8 are configured.

  Here, as shown in FIG. 2, headlines, ruled lines, and the like are preliminarily printed on the continuous paper 1 as preprints 31, timing marks 32 are printed, the paper surface is thermal paper, and the print head of the printing mechanism 4 is used. When overheated, the paper is colored and printed.

  The paper transport mechanism 2 and the discharge transport mechanism 6 are driven by a single motor (not shown), and both or only the discharge transport mechanism 6 can be switched and driven by a clutch. Moreover, this motor can monitor a conveyance amount as a stepping motor or a motor with an encoder.

  The continuous paper 1 is conveyed from the set position on the right side of the drawing to the cutter mechanism 5 by the paper conveyance mechanism 2, and when the timing mark 32 is detected by the timing mark detection sensor 3, a predetermined control unit (not shown) The printing mechanism 4 prints the instructed content from the ATM control unit. Thereafter, the paper is cut by the cutter mechanism 5 by a predetermined amount from the timing mark detection, and the cut receipt paper is transported to the paper discharge port 8 by the discharge transport mechanism 6 and issued to the operator. During the period from the cut to the discharge, only the discharge conveyance mechanism 6 is driven by a clutch (not shown).

  Although not shown in the configuration diagram, a knob for manually turning the paper transport mechanism is provided. When a paper jam occurs, an attendant turns the transport knob to drive the transport mechanisms 2 and 6. The paper can be returned or sent in the discharge direction.

  The issuing operation in the receipt printer of the present invention will be described with reference to FIG. In the state where the continuous paper 1 has been issued, the leading end position is the position of the cutter mechanism 5 (FIG. 3.1-1). When a statement slip is issued from the ATM control unit, the timing mark sensor 3 monitors the arrival of the timing mark 32 on the continuous paper 1 while printing the transaction details, and detects the timing mark 32 (FIG. 3). 1-2) and confirm the paper position. Printing is completed (FIG. 3.1-3), a predetermined amount G is conveyed from the detection of the timing mark, and is cut by the cutter mechanism 5 (FIG. 3.1-4).

  Here, the predetermined amount G is determined so that the predetermined amount G is transported by the length of one sheet. Since it always cuts at this position, the printing position can be started from the same position every time it is issued.

  Next, the cut sheet is conveyed to the sheet discharge port 8 by the discharge conveyance mechanism 6. At this time, it is determined that no slip or failure has occurred when the transport amount after cutting when the paper is detected by the transport path paper sensor 7 falls within the specified range E, and The receipt paper is discharged from the paper discharge port 8 (FIG. 3.1-5). The operator receives the receipt and the receipt printer transaction process is completed.

  Next, a case where the leading edge of the sheet is displaced will be described with reference to FIG. The leading edge of the paper that is on standby due to an erroneous operation by the knob of the clerk or a failure of the drive system mechanism, such as driving the discharge transport 6 after cutting at the time of transaction, or the accompanying rotation of the clutch mechanism that disconnects the drive system operation of the paper transport mechanism 2 Even if the position is at the shifted position D, the cutting process carries the sheet by a predetermined amount G from the detection of the timing mark 32, which is a normal process (FIG. 4.2-4).

  As a result, the normal position can be expected for the next transaction. However, since the printing start position of the paper being transported is deviated, the printing remains on the next receipt paper (Fig. 4.2-5), and the control is performed so that the paper is not printed beyond the position where it is conventionally cut. There is a need to.

  There are two conveyance amounts to be monitored. First, it is monitored that the conveyance amount B from the end of printing to the cut conveyance is longer than the distance A from the print head to the cutter. Since the distance A is a physical distance, it is a hard and fixed length, and the distance B from the end of printing to cut conveyance varies depending on the amount of information to be printed, but if B> A, If there is no paper misalignment such as slip, printing does not remain on the next paper.

  Even if the printable area is expanded due to customer requirements, etc., the distance B from the end of printing to the cut conveyance is the amount of printing that can be accommodated in one receipt sheet, from the end of printing to the cut conveyance. If the distance B is not shorter than the distance A from the print head to the cutter, it is processed as normal.

  In other words, it varies depending on the difference in the printing format, for example, the amount of line feeds for each line and the number of printed lines, but with this method, it is determined by the distance from the end of printing to the cut conveyance. Even if there is a print out of this control, it is assumed that the print will remain on the next receipt. As a result, it is possible to determine that printing 9 remains on the next sheet with a minimum deviation in the transport amount.

  The second is to monitor the conveyance amount after the cut because it is assumed that a failure occurs when the timing mark is detected and the regular conveyance amount cannot be sent, so that it is cut during the printing of the transaction receipt. This control will be described with reference to FIG.

  During transaction receipt printing, a predetermined amount G of paper is sent from the timing mark 32 and cut (FIG. 5.3-4). However, after printing, if a paper jam occurs due to catching at the leading edge of the paper, or if the paper conveyance force decreases due to deterioration or wear of the paper conveyance system and the normal conveyance amount cannot be sent, it is shorter than the original. It was cut by the length (Fig. 5.3-4), and printing was left on the next receipt paper because it was in the middle of printing 9 (Fig. 5.3-5). In this state, the control side recognizes and controls that the paper is normally transported. Therefore, a deviation that is not recognized on the print control side as in this state is separated from the timing mark control. It is necessary to provide a mechanism that can detect the length of the.

  Therefore, if the conveyance detection sensor 7 for monitoring the conveyance of the paper passing after the cut does not reach the conveyance detection mechanism 7 by the conveyance of the predetermined amount E from the cutting position, the receipt paper is short and there is a remaining print on the next receipt paper. 9, the receipt paper and the next receipt paper are collected F and reprinted.

  The cause of the printing straddling on the next sheet is assumed to be a printing start position shift and a case where the transaction receipt is cut during printing of the transaction receipt. By using the two monitoring controls, the control to monitor that the distance from the print head to the cutter is longer than A and the control to monitor the transport amount after cutting, it is possible to completely prevent printing from being laid on the next sheet. Is possible.

  In the above example, the mechanism for determining the cutting position by the timing mark has been described. However, the paper feed control for controlling the predetermined pulse to determine the paper conveyance and cutting, the paper conveyance amount considering the paper conveyance amount, or the timing This control is also effective for a positioning mechanism and control using a conveyance path detection mechanism that recognizes the conveyance state of a sheet instead of a mark and determines a printing position and a cutting position.

  In the description of this control, the paper length is estimated based on whether or not the conveyance detection mechanism different from the timing mark is reached, and it is determined whether or not it is a normal paper length. The method of monitoring the receipt paper length by monitoring the paper passing time is also effective as in this control.

  Hereinafter, control for cutting without considering the timing mark will be described. The continuous paper is a blank paper on which the pre-printing 31 such as the headlines and ruled lines shown in FIG. 2 and the timing mark 32 are not printed, and the surface of the paper is a thermal paper, and is overheated by the print head of the printing mechanism 4. The paper is colored and printed. As shown in FIG. 2, the contents to be printed are simultaneously printed by a receipt printer with a fixed format of pre-printing 31 such as headlines and ruled lines, and customer transaction information.

  Although the same operation as the mechanism for determining the cutting position by the timing mark is performed, the point of difference from this operation is the control of the trigger for cutting the sheets one by one. Using the standby position after the paper cut as a base point, a predetermined pulse is controlled to carry and cut the paper.

  It should be noted that the trigger for cutting is that printing has been completed and the final print character has passed through the cutter, that is, the relationship between the distance B from the end of printing to the cutter transport and the distance A from the print to the cutter is B It is an essential condition that> A.

  In this case, even when the cutting opportunity and method are different, the state in which the printing remains on the next sheet, that is, the relationship between the paper and the printing position is a comparison between the distance A from the printing to the cutter and the distance B from the printing end to the cutter conveyance. Therefore, this control can be applied as it is, or the control can be diverted by changing constants and the like.
