Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bookkeeping machine, and particularly to a return method after printing on a medium is completed.

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

FIG. 1 shows a perspective view of such a bank bookkeeping system. 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, the bankbook 1 is sent by the operator or the customer.
When the passbook 1 is set, the sensor 9 detects the passbook 1. As a result, the shutter 10 is opened, and the feed roller mechanism 6 is closed and rotated in the suction direction. And the bottom edge of passbook 1 is sensor 1
Passbook 1 is sucked until it is detected by 1.
When the lower end of the bankbook is detected, the rotation of the feed roller mechanism 6 is stopped and the bankbook is positioned at the reading position.
Then, the magnetic head MH moves to read information, which is carried out by the amplifier AMP in Figure 3.
Amplification, shaping, and level conversion are performed by 1, and a check circuit is performed via the read/write control circuit RWC.
Sent to CHC. 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, and the printing unit 4 passes through the print line detection unit 8.
The bankbook 1 is sent to the printing position and 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, the information is sucked further for printing as described above, but if it is not OK again, the movable head MH is moved again and the information is 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 result of the check is correct, the roller mechanism is again rotated in the ejection direction and returned via the shutter mechanism 10. If the check result 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 describes the operation of the medium passbook 1 in a conventional bookkeeping machine, the writing of information to the magnetic storage unit 2,
Alternatively, reading has been explained, but now the method of magnetic recording will be explained.

The magnetic recording section 2 originally has one storage area,
Only one piece of information needs to be stored, but if a bank passbook is not stored properly, there is a high probability that the information will be changed or disturbed by external magnetic fields (for example, from television). Therefore, the conventional magnetic storage unit 2 has two storage areas, for example, and a method is used in which the above-mentioned probability is halved by writing the same information in each block. Therefore,
When updating data is written and read and checked after printing is completed in Figure 3b, comparison with written information and BCC or CRC check results are performed for all block information, and all of these results are You must return your passbook only when you are satisfied.

However, a problem remains here. If the check result of one of the two blocks is correct, but the check result of the other block is judged to be incorrect, the block is not returned and is taken into the bookkeeping machine. If the data is captured in the bookkeeping machine, the machine will go down and the customer will not be able to take any countermeasures against it, and will have to be adjusted by a bank employee or maintenance person.

This is extremely irrational if the bookkeeping machine goes down and the passbook is taken in even though the information is correctly stored in one block.

The present invention has been made in order to improve the above drawbacks, and after printing on a medium having a magnetic storage section, a magnetic head writes information to the magnetic storage section, reads the information, and converts the read information. The next operation of the medium is determined based on the result of the check, and the magnetic storage section has N blocks (N: an integer of 2 or more) of storage areas, and each storage area is The same information is stored in the recording machine, and the medium is returned only when the check of the information read by the magnetic head is determined to be correct for all blocks. If the read information is determined to be incorrect, the magnetic head reads it again, and the read information is checked at a lower level than the previous check, and as a result of this check, the information in all blocks is correct. The feature is that the medium can be returned at any time.

The return method according to the present invention will be explained below with reference to the drawings. FIG. 5 is a flowchart showing the return operation after printing is completed in the bookkeeping machine.

First, when the printing section 4 finishes printing on the bankbook 1, the roller mechanism 6 is rotated in the ejection direction. When the lower end of the bankbook 1 is detected by the sensor 11 during the movement in the discharge direction, the roller mechanism 6 stops rotating and holds the bankbook 1 at the reading position. Then, the magnetic head HM moves and new information is written into the two blocks of the magnetic storage section 2 in the same way. After that, the head HM is reversed, and the information just written is read on the return trip. The receipt information is checked by the check circuit CHC. At this time, the check is BCC check 2 is CRC
In addition to checking, one-to-one correspondence with written information is also performed. As a result of the check, if the information in the two blocks is correct, the roller mechanism 6 is further rotated in the ejection direction and the passbook 1 is returned. If it is determined that the block is incorrect in check 1, a check is made to see if the information in one of the two blocks is correct. If one block is determined to be correct, the head HM moves back and forth again to perform writing and reading again. If both blocks are determined to be incorrect, the number of times they have been written/read is checked, and if it is less than N times, writing/reading and check 2 are performed again.

The check method in check 2 is check 1
is performed at a lower level than the level in . That is, for example, only the comparison with the written information is performed, and the BCC check or CRC check is omitted. As a result, if both blocks are determined to be correct, the roller mechanism 6 is rotated in the ejection direction and the passbook 1 is returned. When both are judged to be incorrect in check 2 and the number of checks in check 2 is greater than N, the bankbook 1 is taken into a bookkeeping machine without being returned, and the cash handling machine including the bookkeeping machine is shut down.

In the above description, an example has been described in which the magnetic head moves to perform writing and reading in the magnetic storage section, but the magnetic head may stop and the bankbook moves. Furthermore, when retrying after check 1 or 2, writing may be omitted and only reading may be performed, or writing and reading may be performed simultaneously during the outward movement of the magnetic head.

As explained above, according to the present invention, it is possible to significantly reduce the number of times a bookkeeping machine goes down without changing the conventional conditions.

Claims (1)

[Scope of Claims] 1. After printing on a medium having a magnetic storage section, a magnetic head writes information to the magnetic storage section, reads the information and checks the read information, and according to the result of the check. The magnetic storage unit determines the next operation of the medium, and the magnetic storage unit has a storage area of N blocks (N: an integer of 2 or more), and the same information is stored in each storage area. Sometimes, when the information of at least one block is correctly read by the magnetic head, it is printed on the medium based on that information, and when the medium is returned, the information written and read by the magnetic head is checked. In the return method of a recording machine that returns the medium only if all blocks are determined to be correct, if the read information of at least one block is determined to be correct and the remaining information is incorrect, the medium is re-magnetized. After the information is written by the head, it is read and the read information is checked at a lower level than the previous check.On the other hand, if the read information of all blocks is judged to be incorrect, the information by the magnetic head is checked again. A medium in a bookkeeping machine characterized in that the medium is read after writing, the read information is checked at the same level as the previous check, and the medium is returned when the information in all blocks is correct as a result of the check. Return method.
