JP4625771B2 - Passbook bar code reader - Google Patents

Description

  The present invention relates to a barcode reader that reads a barcode printed on a booklet-like paper sheet such as a passbook, and in particular, reads a plurality of associated barcode patterns printed on each page of the passbook. The present invention relates to a passbook bar code reading apparatus capable of performing correction without providing a special mechanism.

  An automated teller machine (ATM) is used in financial institutions such as banks. The passbook entry machine installed in the ATM to fill in transaction data is used to check the validity of the page when printing new transaction data or when turning pages by the automatic page change mechanism. The presence / absence of a barcode consisting of a plurality of barcodes printed on the barcode or the like, and the determination of whether the barcode is thin or thick are performed.

  The bar code has a horizontal bar code (horizontal bar code) and a vertical bar code (vertical bar code) at the top or bottom of the passbook. ) Always exist, and there are patterns that are used to search bar codes in order from the reference bar code, and patterns that do not have a reference bar code that serves as a search reference. Conventionally, this type of apparatus has been disclosed in JP-A-7-85202 (Patent Document 1).

JP-A-7-85202

  When the bankbook is conveyed for barcode reading, when the bankbook rushes between the conveyance rollers, the page may be swelled downward with respect to the conveyance direction due to the resistance generated between the conveyance roller and the bankbook. In particular, in a pattern where there is no reference barcode for the horizontal barcode, if the page is shifted, the vertical position of the read barcode will be shifted from the correct position due to the page shift. There was a problem that the barcode pattern could not be recognized normally because the code could not be recognized.

  In order to solve this problem, when a bar code that cannot be recognized as being in the correct position is read, it is conveyed in the direction opposite to the first reading direction, and the bar code is read at this time. In this way, the deviation of the barcode position caused by the rising of the page during the first conveyance of the passbook can be smoothed and corrected by being pressed against the passbook roller when the passbook enters the conveyance roller. The barcode pattern can be recognized normally.

  According to the present invention, barcode reading correction can be easily performed without providing a special mechanism in the reading device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 2 is a schematic side view of a bankbook entry machine equipped with a barcode reader according to an embodiment of the present invention. 201 is a passbook insertion / extraction port for taking in or discharging a passbook, 202 is a bar code reader for reading a bar code, 203 is a magnetic head for reading or writing magnetic information of a magnetic stripe attached to the passbook, and 204 is transaction information in the passbook Print head, 205 is an automatic page changing mechanism for turning the page of the passbook, 206 is a control unit for controlling the passbook writing machine, 207 is a memory of the control unit 206, 211-220 are rotated by a motor (not shown) and carry the passbook It is a conveyance roller.

  FIG. 1 is a processing flowchart of the embodiment. When a customer inserts a passbook (not shown) from the passbook insertion / exit port 201 (S101), the power from a motor (not shown) is obtained and the transfer roller 220 rotates from the transfer roller 211 to pull in the passbook (S102). When the upper end of the bar code is detected, the control unit 206 instructs the bar code reader 202 to take in bar code information, thereby starting bar code reading (S103), and stores the bar code information in the memory 207.

  When the bottom of the passbook is detected, reading is terminated. After the passbook has been transported to a predetermined position, the transport motor is stopped (S104), and the control unit 206 performs barcode presence / absence analysis (S105) from the image information stored in the memory 207. The bar code analysis can be started from when the reading of the bar code is completed, and therefore may be performed before the transport motor is stopped (S104).

  FIG. 3 is an enlarged view of a state when reading a barcode. When the passbook 304 enters between the transport roller 301 and the transport roller 302 before passing through the bar code reader 305, the passbook 304 becomes 303 as a result of the resistance generated between the transport roller 301 and the transport roller 302 and the passbook. There may be excitement.

  The memory 207 stores passbook bar code information as image data. FIG. 5 is a diagram showing a barcode analysis process. The passbook 530 is printed with a first barcode 501 (without barcode), a second barcode 502 (with barcode), a third barcode 503 (without barcode), and a fourth barcode 504 (with barcode). ing.

  At the time of analyzing the first bar code, the control unit 206 searches the bar code by analyzing the memory 207 within the range of the downward search range 505 and the upward direction 506 from the upper end of the bankbook 530. If the control unit 206 recognizes that the barcode is within the searched range, the barcode is considered to be present. However, if a shift occurs as in 303, the bar code is shifted downward.

  In the second bar code search, the control unit 206 analyzes the memory 207 and searches for a bar code within a range of a downward search range 507 and an upward direction 508 at a distance 521 from the upper end of the passbook 530. If the control unit 206 recognizes that the barcode is within the searched range, the barcode is considered to be present, but due to the deviation, the barcode does not belong to the search range of the first barcode and also belongs to the search range of the second barcode. If the bar code is present in the gray zone 514, it is impossible to recognize whether the bar code is the first bar code or the second bar code. When it is determined that the recognition is impossible, the sheet is conveyed in the opposite direction (S107) and the barcode is read again (S108).

  FIG. 4 is an enlarged view of the state when the barcode is read again. Even if the bankbook 404 rises and deviates like 403, it is pressed while being conveyed by the conveying roller 401 and the conveying roller 402 to be flattened, and when reading by the barcode reading device 405, it is read in a state in which the deviation is corrected. be able to.

  Here again, when it is determined that recognition is not possible (S111), there is a possibility of printing misalignment, so a reading abnormality is reported and the process is terminated.

  In this description, the case where there is a barcode on the upper end side of the passbook has been described, but the present invention is also effective when there is a barcode on the lower end side. In this case, the conveyance direction in which page misalignment occurs and the page misalignment are corrected. Needless to say, the transport direction is opposite to that described above.

  Further, in the present invention, correction is performed by reversing the conveyance direction when reading becomes impossible by barcode reading. However, the magnetic stripe attached to the passbook of the present invention can be read while the passbook is being conveyed. Application to stripe reading is also possible. When the magnetic stripe is read by the magnetic head 203 while pulling the passbook from the passbook insertion / discharge port 201, the resistance force by the transfer roller becomes a reading noise in the pulling direction and becomes impossible to read, but is transferred to the passbook insertion / discharge port 201 with the transfer direction reversed It may be possible to read without reading noise.
