Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for reading information from a storage section of a medium (for example, a bank passbook) having a magnetic storage section using a magnetic head, and particularly a method for reading information by stopping the medium and moving the magnetic head. Regarding.

In a cash dispensing machine or a cash deposit machine, the bank passbook is equipped with a magnetic storage section called a magnetic stripe, and the account number, the page or line of the passbook to be printed next, the balance, etc. are recorded on the magnetic stripe. It is becoming more and more common to memorize things.

FIG. 1 shows a perspective view of such a bank passbook.
A passbook 1 is made up of a plurality of sheets and a cover bound together, and a magnetic stripe 2 is attached to a part of the cover.

FIG. 2 schematically shows a bookkeeping machine used in a cash dispensing machine or a cash deposit machine.

The bookkeeping machine can be roughly divided into an inserter section 3 that controls the conveyance of the passbook 1, and a printing section 4 connected to the inserter section 3. The printing part 4 is the inserter part 3
Information corresponding to the details of the transaction is printed on the passbook 1 sent from the bank. The inserter section 4 includes a medium pathway 5 consisting of a pair of side plates, a feed roller mechanism 6 for transporting the passbook 1, a magnetic reading/writing section 7,
A print line detection unit 8, a sensor 9 for detecting the bankbook 1, and a shutter mechanism 10 provided on the upper part of the pathway 5.
Consists of etc.

A control block diagram of such a bookkeeping machine will be explained with reference to FIG. In FIG. 3, CCP is a central control device, which includes a pulse motor PM that drives the feed roller mechanism 6, a pulse motor drive circuit PMDU that drives and controls it, a shutter opening/closing drive circuit SOCD, writing to the magnetic storage unit MS,
Alternatively, a magnetic read/write system consisting of a magnetic head MH for reading, an amplifier AMP1, a read/write control circuit RWC, a check circuit CHC for checking the read information, an amplifier AMP2 for amplifying signals from various sensors, etc. are connected. ing.

The conventional operation of such a bookkeeping machine will be explained along the flowchart shown in FIG.

First, when a bankbook is set by an operator or a customer, the bankbook 1 is detected by the sensor 9. As a result, the shutter 10 is opened, the feed roller mechanism 6 is closed, and rotated in the suction direction. The bankbook 1 is then sucked in until the lower end of the bankbook 1 is detected by the sensor 11. The rotation of the feed roller mechanism 6 where the lower end of the passbook is detected is stopped, and the passbook is positioned at the reading position. Then, the magnetic head MH moves to read information, which is amplified, shaped, and level-converted by the amplifier AMP1 in FIG. 3, and sent to the check circuit CHC via the read/write control circuit RWC. The check circuit CHC checks the information by BCC check or CRC check. If the check is OK, that is, the read information is accurate, the roller mechanism 6 is further rotated in the suction direction, sent to the printing section 4 through the print line detection section 8, positioned at the printing position, and printing on the bankbook 1 is performed. . If an error occurs in the read information as a result of the check, the magnetic head MH moves again and reads the magnetic storage section 2. Then, if it is checked again and it is OK, it will be sucked in again for printing as before, but if it is not OK again, the moving head MH will be moved again and the information will be read. When the number of retries reaches the specified number N, the bankbook 1 is ejected without being retried for reading or printing.

The operation after the printing section 4 finishes printing will be explained along the line b. When printing is completed, the roller mechanism 6 is rotated in the ejection direction. When the lower end of the bankbook 1 is detected by the sensor 11, the rotation of the roller mechanism 6 is stopped, and the magnetic head MH is first moved in the forward direction to write updated data. Then, it is reversely moved in the backward direction, and the previously written data is read at that time. A data check is then performed in the check circuit CHC. This check
In addition to the BCC check or CRC check, one-to-one correspondence between write data and read data is also performed. If the check result is correct, the roller mechanism is rotated again in the ejection direction and returned via the shutter mechanism 10. If the result of the check is incorrect, the magnetic head MH is made to write and read again, and the check is performed again. When the number of retries reaches N times, the passbook 1 is taken into the bookkeeping machine without being returned.

The above is an explanation of magnetic reading in a conventional bookkeeping machine, but the problem here is the movement of the bankbook that occurs when the magnetic head moves and reads the stationary bankbook 1. . That is,
The magnetic head MH moves while contacting the storage section 2 of the bankbook 1 with a certain pressure.
Even if the passbook 1 is held by the roller mechanism, the passbook 1 may be moved due to backlash or the like. Therefore, when reading is performed again, a relative movement occurs between the passbook 1 and the magnetic head MH, and the read information cannot be read correctly, resulting in repeated retries. For this reason, it is conceivable to provide a mechanism to hold the passbook 1 at the reading position, but it is difficult to hold the passbook 1 completely without relative movement, and the holding mechanism must be placed at the holding position and the retracted position relative to the pathway. The mechanism must be held only when necessary, complicating the mechanism.

The present invention has been made in view of these drawbacks, and when reading the result of the check, the reading position of the bankbook is set again, and then the reading is performed by a magnetic head, and the reading is performed along the medium pathway. In a magnetic read control method, the medium having a magnetic storage section that has been transported is detected and stopped at a predetermined reading position, and the information stored in the magnetic storage section is read by moving a magnetic head, If the read information is incorrect, the medium is once transferred from the reading position to another position, the medium is detected again and stopped at the reading position, and the magnetic head is moved again to read the previous magnetic memory. It is characterized by being able to read information on the parts.

The magnetic reading system according to the present invention will be explained below with reference to the drawings.

FIG. 5 is a float chart showing the operation of the system according to the invention. a indicates the operation when the passbook 1 is sucked in, that is, before printing, and b indicates the operation when the passbook 1 is ejected, that is, after printing. In a, when the information read by the magnetic head MH is NG and the number of times of reading is N times or less, when the magnetic storage unit 2 is read again by the MH, the bankbook 1 is reset to the reading position again. is different from Fig. 4a. In other words, if the data check result is incorrect and the number of readings is N or less, in the present invention, the roller mechanism 6
is rotated by a certain amount in the ejection direction to temporarily move the passbook 1 from the reading position to another position on the pathway 5, and further the roller mechanism 6 is reversed in the suction direction to detect the lower end of the passbook 1 by the sensor 11, After setting the passbook 1 back to the reading position, it is read by the magnetic head MH.

The same applies to case b; if the check result is incorrect and the number of readings is N or less, the roller mechanism 6 is rotated by a certain amount in the suction direction to move the passbook 1 from the reading position to another position on the pathway 5. position, and further reverses the roller mechanism 6 in the ejection direction, detects the lower end of the passbook 1 by the sensor 11, and removes the passbook 1.
After resetting the magnetic head to the reading position,
It is read by MH.

Therefore, the reading error caused by the movement of the bankbook 1 during the previous reading is canceled before retrying, and the influence of the movement is removed.

In the above description, the moving direction of the magnetic head MH is the same as the moving direction of the passbook, but the two may be different. Also, in figure b,
Writing and reading may be performed simultaneously during outward movement. Further, the reading position may be determined by detecting the upper end of the medium.

Further, in both cases a and b, the medium is detected and the rollers are stopped immediately, but in reality, the stopping position from the suction direction to the reading position and the stopping position from the ejection direction are different due to inertia. Therefore, the suction direction is the standard, and in the case of the discharge direction, the sensor 11 detects the passbook 1 in the discharge direction as shown by the dotted line in Fig. 5b.
Immediately after detecting , the reading position can be kept constant by allowing a certain amount of liquid to pass through without stopping the roller mechanism, and by reversing the roller mechanism 6 in the suction direction and stopping it by the sensor 11, the reading position can always be kept constant.
