Abstract
In a transaction record storing device of a transaction machine, electronic journal data including transaction contents are stored into a storage medium whose stored data is unalterable or a storage medium which keeps its data alteration record. This ensures a guarantee of the truth with respect to the electronic journal data stored in the storage medium.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a transaction record storing device for electronically recording the contents of transactions carried out in an automatic transaction machine installed in a bank or the like, and further relates to a transaction machine provided with functions of such a transaction record storing device.
2. Description of the Related Art
When a transaction such as deposit, withdrawal or transfer is performed in an automatic transaction machine such as an automatic tellers machine installed in a bank or the like, the contents of the performed transaction should be recorded as journal data (machine operation record data).
It was stipulated in a former law that the following conditions should be satisfied with respect to recordation of journal data:
To print on a paper medium an operation record in an automatic tellers machine.
To keep the printed paper medium for a predetermined time.
Therefore, every time a transaction occurs in an automatic tellers machine having a configuration as shown in
FIG. 10
, data indicative of the contents of the transaction is transferred from a control section
100
to a journal printer
450
where the transaction contents and an emboss image of a card used in the transaction are printed on journal paper P, and the printed journal paper P is preserved for a predetermined time in a bank or the like.
FIG. 11
is a block diagram for explaining an operation of the control section
100
. The control section
100
comprises a communication control section
531
, a transaction control section
501
and a journal data control section
541
. The journal data control section
541
receives center information from the communication control section
531
, transaction information such as a transaction time, a transaction item and a transaction amount from the transaction control section
501
, and emboss image data on the surface of a card from a card unit
430
, and edits them as journal data. Then, the journal data control section
541
confirms setting of the journal paper P via a paper runout detecting section (not shown) of the journal printer
450
, and transfers the journal data to the journal printer
450
where the journal data is printed on the journal paper P.
According to the foregoing conventional technique, however, since the journal data should be printed on the journal paper P, when the journal paper P runs out, the machine is stopped in operation or the journal data control section
541
transfers the journal data to an external storage device such as a hard disk drive
810
for temporary storage therein until a new roll of journal paper P is supplemented. In the latter case, when the journal paper P is supplemented, the temporarily stored journal data is returned to the journal data control section
541
which then transfers the journal data to the journal printer
450
for printing on the journal paper P. When the printing is finished, the journal data stored in the external storage device is deleted.
Due to the foregoing constraint on the preserving manner of the journal data, the following problems have been raised:
As described above, the journal data is recorded and preserved on the paper medium. Thus, the journal printer
450
as well as the journal paper P are provided in the automatic tellers machine. Due to the sizes of the journal paper P and the machine, the number of printable transaction cases without supplementing the journal paper P can not be increased so much. Specifically, the number of printable transaction cases is about 2,000 per roll of the journal paper P and the machine has a space for only about two rolls of the journal paper P. Thus, if transactions are active, it is necessary that a clerk in charge manually supplements and recovers the journal paper P at frequent intervals.
Since the size of the journal paper P is large while the number of printable transaction cases per roll is not so large, an extensive space is required for keeping rolls of the journal paper P.
When the journal printer
450
is a thermal printer, the printed contents may become illegible due to aged deterioration.
When the journal data is temporarily stored in an external storage device such as the hard disk drive
810
, if the external storage device is subjected to failure, the journal data is lost and can not be restored.
In consideration of the foregoing problems, the law has been revised to allow journal data to be preserved as electronic data. Still in this case, the following conditions should be satisfied:
<Guarantee of Truth>
To make it possible to confirm a record of alteration, such as correction, deletion or addition, of data.
To keep a document about a history of computer processing (e.g. description as to when, where and how writing of data was performed).
<Guarantee of Visibility>
To install an output device such as a display or a printer so that electronic data is visible.
To make it possible to retrieve data by setting a condition.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a technique which can particularly satisfy the condition of the truth guarantee for preserving journal data as electronic data.
It is another object of the present invention to provide a technique wherein a delay in storage speed caused by a property of a storage medium used for storing electronic journal data is prevented from affecting reception of sequentially generated electronic journal data.
It is another object of the present invention to provide a technique wherein even if storage of electronic journal data into a storage medium fails, the storage of the journal data can be ensured.
It is another object of the present invention to provide a technique which allows, while writing electronic journal data, reception of new electronic journal data so as to prevent stoppage of a transaction machine.
It is another object of the present invention to provide a technique which can enhance safety of data storage by preventing received new electronic journal data from being lost, particularly in an arrangement wherein while writing electronic journal data, reception of new electronic journal data is allowed.
According to one aspect of the present invention, there is provided a transaction record storing device comprising a section for loading therein one of a first storage medium whose stored data is unalterable and a second storage medium which keeps its data alteration record, and for storing electronic journal data including at least transaction contents into the one of the first and second storage mediums.
Using such a first or second storage medium as a storage medium for the electronic journal data, a guarantee of the truth is ensured with respect to the electronic journal data stored therein. As such a storage medium, a CD-R or the like may be used.
It may be arranged that the first storage medium is an exchangeable storage medium into which the electronic journal data is written in a disk-at-once manner. Since the electronic journal data is written in the disk-at-once manner, the electronic journal data stored in the storage medium is unalterable.
It may be arranged that the second storage medium is an exchangeable storage medium into which new data is writable while stored data remains unchanged therein. In this case, the data may be written into the storage medium in a track-at-once or packet-write manner.
It may be arranged that given management data for identifying the one of the first and second storage mediums is recorded in advance as a header thereof. In this arrangement, the given data (e.g. serial number) which can be used for management of the storage medium is recorded in advance, such as upon production of the storage medium, as a header (e.g. volume label) of the storage medium. Thus, when the header includes such data not used for the medium management or when a plurality of headers having the same contents exist, it is known that an unfair practice has occurred. Accordingly, by managing the headers of the storage mediums, such an unfair practice can be found out quickly. Further, this arrangement facilitates retrieval of the preserved electronic journal data through easy identification of the required storage medium.
It may be arranged that given management data for identifying the one of the first and second storage mediums is recorded as a header thereof upon writing the electronic journal data thereinto. In this arrangement, the given management data is recorded upon writing the electronic journal data into the storage medium.
It may be arranged that given management data for identifying the one of the first and second storage mediums is recorded on a casing thereof after finishing writing of the electronic journal data thereinto. This facilitates easy identification of the required storage medium by, for example, printing a machine number and a medium number (serial number) on the surface of the casing of the storage medium.
According to another aspect of the present invention, there is provided a transaction record storing device comprising an overwritable buffer means for temporarily storing electronic journal data including at least transaction contents; and a data writing means for loading therein one of a first storage medium whose stored data is unalterable and a second storage medium which keeps its data alteration record, and for reading the electronic journal data from the buffer means and writing the read electronic journal data into the one of the first and second storage mediums.
There is no particular limitation to a structure of the buffer means. It is preferable, however, that the buffer means is high in data write and read speed and may be a hard disk drive, an MO drive or the like. The buffer means is overwritable because the buffer means does not need to keep such electronic journal data that has been written into the storage medium, and because it is better to release an area of the buffer means to receive new electronic journal data therein.
It may be arranged that the data writing means reads the electronic journal data from the buffer means and writes the read electronic journal data into the first storage medium when a storage amount of the electronic journal data in the buffer means reaches a predetermined value or when an operator inputs a corresponding command, and that the buffer means is allowed to store new electronic journal data after writing of the electronic journal data into the first storage medium is finished. With this arrangement, even if the writing of the electronic journal data into the storage medium fails, the electronic journal data subjected to the writing is maintained in the buffer means. In this arrangement, the electronic journal data is read from the buffer means and written into the storage medium when the storage amount in the buffer means reaches the predetermined value. The reason is as follows: When, for example, the electronic journal data is written into the storage medium in the disk-at-once manner, the storage efficiency of the storage medium is reduced if the data is written into the storage medium in a small amount because a nonused area of the storage medium is wasted. As appreciated, there is no problem with respect to the arrangement wherein the electronic journal data is written into the storage medium in response to the corresponding command inputted by the operator.
It may be arranged that when the writing of the electronic journal data into the first storage medium fails, the data writing means reads again from beginning the electronic journal data stored in the buffer means and writes the read electronic journal data into a new storage medium. As described above, since the electronic journal data is maintained when the writing thereof into the storage medium fails, it is possible to write it into a new storage medium.
It may be arranged that the buffer means stores a plurality of files and, while the electronic journal data is written into the first storage medium from one of the files, new electronic journal data is stored into another of the files. With this arrangement, even while the electronic journal data is written into the storage medium, new electronic journal data can be received into the buffer means, thereby preventing stoppage of the device. This is particularly useful when the write speed of the storage medium is low.
It may be arranged that the transaction record storing device further comprises another overwritable buffer means for storing the electronic journal data of the same contents. For realizing this, the electronic journal data of the same contents may be simultaneously stored into a plurality of buffer means in a hardware fashion, or the electronic journal data is first stored into one of the buffer means and then copied into another buffer means in a software mirroring fashion.
It may be arranged that the electronic journal data stored in the buffer means is read in sequence and written into the second storage medium and that the electronic journal data subjected to writing into the second storage medium is maintained as it is in the buffer means until a storage amount of the electronic journal data in the second storage medium reaches a predetermined value and, when the storage amount reaches the predetermined value, a first area in the buffer means storing the electronic journal data subjected to the writing into the second storage medium is released to allow new electronic journal data to be overwritten in the first area. With this arrangement, until the storage amount of the electronic journal data in the storage medium reaches the predetermined value (e.g. maximum storage capacity of the storage medium), the electronic journal data subjected to the writing Is maintained in the buffer means. Thus, even if the writing of the electronic journal data into the storage medium fails, the electronic journal data subjected to the writing is maintained in the buffer means. On the other hand, when the writing into the storage medium is successful (i.e. when the storage amount in the storage medium reaches the predetermined value), an area in the buffer means storing the electronic journal data subjected to the writing is released to allow new electronic journal data to be overwritten in that area.
It may be arranged that a storage capacity of the buffer means is set greater than a storage capacity of the second storage medium so that a second area in the buffer means other than the first area is always allowed to store new electronic journal data. With this arrangement, new electronic journal data can be always stored into the buffer means while the stored electronic journal data is written into the storage medium in sequence.
It may be arranged that when the writing of the electronic journal data into the second storage medium fails, the data writing means reads again from beginning the electronic journal data stored in the first area of the buffer means and writes the read electronic journal data into a new storage medium. As described above, since the electronic journal data subjected to the writing into the storage medium is maintained until the storage amount thereof in the storage medium reaches the predetermined value, when the writing thereof into the storage medium fails, it is possible to write the maintained electronic journal data into a new storage medium.
It may be arranged that the transaction record storing device further comprises an address managing section for managing a next write pointer for appointing a write start address of electronic journal data to be stored next into the buffer means, an output pointer for appointing a read address in the buffer means when writing electronic journal data from the buffer means into the second storage medium, and an initial value pointer for appointing a first read address in the buffer means of electronic journal data subjected to writing into the second storage medium, wherein new electronic journal data is stored into the buffer means according to the write start address appointed by the next write pointer, wherein the first read address is set to the initial value pointer when starting reading the electronic journal data from the buffer means, wherein the electronic journal data is read in sequence from the buffer means according to the read address appointed by the output pointer and written into the second storage medium, wherein the electronic journal data in the buffer means from the first read address appointed by the initial value pointer to the read address appointed by the output pointer is maintained as it is until the storage amount reaches the predetermined value, and wherein when the storage amount reaches the predetermined value, the first read address appointed by the initial value pointer is set to coincide with the read address appointed by the output pointer so that new electronic journal data is overwritable in the first area of the buffer means. With this arrangement, using the pointers, the electronic journal data can be read in sequence from the buffer means and written into the storage medium, while the electronic journal data subjected to the writing into the storage medium is maintained until the storage amount in the storage medium reaches the predetermined value, and further, when the storage amount reaches the predetermined value, new electronic journal data can be overwritten on the maintained electronic journal data.
It may be arranged that a storage capacity of the buffer means is set greater than a storage capacity of the second storage medium and that the write start address of the next write pointer is set to an address in an area other than the first area of the buffer means. With this arrangement, new electronic journal data can be always stored into the buffer means while the stored electronic journal data is written into the storage medium in sequence.
It may be arranged that when the writing of the electronic journal data into the second storage medium fails, the data writing means reads again from beginning the electronic journal data stored in the buffer means from the first read address appointed by the initial value pointer to the read address appointed by the output pointer and writes the read electronic journal data into a new storage medium. As described above, since the electronic journal data subjected to the writing into the storage medium is maintained until the storage amount thereof in the storage medium reaches the predetermined value, when the writing thereof into the storage medium fails, it is possible to write the maintained electronic journal data into a new storage medium.
According to another aspect of the present invention, there is provided a transaction machine for performing transaction processing about money through manipulation by an operator, the machine comprising a transaction storing section for loading therein one of a first storage medium whose stored data is unalterable and a second storage medium which keeps its data alteration record, and for electronically recording electronic journal data about performed transaction contents into the one of the first and second storage mediums.
The transaction machine includes an automatic tellers machine installed in a bank or the like, and the transaction storing section corresponds to one of the foregoing transaction record storing devices.

180
.
The hard disk control application
560
stores electronic journal data transferred from the journal data control application
540
, into the hard disk
110
as a journal file A or B. Further, the hard disk control application
560
copies the journal file stored in the hard disk
110
into the hard disk
140
in sequence. Thus, the hard disk
140
serves as a mirror disk of the hard disk
110
.
Now, an operation of the foregoing automatic tellers machine will be described hereinbelow.
A procedure of writing electronic journal data into the hard disks
110
and
140
will be first described. When, for example, a withdrawal transaction is performed, a customer inserts a card into the card unit
430
and inputs a transaction item, a password and a transaction amount using the customer operating touch panel
200
and the customer side LCD
210
.
The machine control application
510
sends the inputted data to the host via the communication control application
530
to confirm whether the contents of the transaction are warrantable. Specifically, the machine control application
510
notifies the password, an account number, the transaction item, the transaction amount and the like to the host and receives transaction propriety, notification print data, particulars print data and the like from the host.
When it is notified from the host that the transaction is proper, the machine control application
510
handles the transaction as having been established. Specifically, the machine control application
510
request the unit control application
520
to read card emboss image data using the card unit
430
and transfers the card emboss image data to the transaction data control application
500
along with the password, the account number, the transaction item, the transaction amount, the notification print data, the particulars print data and the like.
As shown in
FIG. 4
, the transaction data control application
500
edits those data to produce electronic journal data comprising the following transaction contents:
Transaction Time
Account Number (including Bank Number and Branch Number)
Transaction Item (Withdrawal/ Deposit/Transfer/ Entry/Inquiry)
Transaction Amount
Handling Fee
Card Emboss Data
The machine control application
510
requests the unit control application
520
to cause the bill unit
400
and the coin unit
410
to discharge cash, cause the card unit
430
to return a card and further cause the passbook unit
420
and the receipt unit
440
to perform given printing and then discharge a passbook and a receipt via the passbook in-out port
421
and the receipt issuing port
431
, respectively.
Then, the machine control application
510
receives the edited electronic journal data from the transaction data control application
500
and transfers it to the journal data control application
540
. Subsequently, the journal data control application
540
transfers the electronic journal data to the hard disk control application
560
and requests it to store the journal data into the hard disk
110
.
The hard disk control application
560
stores the electronic journal data transferred from the journal data control application
540
, into the journal file A or B in the hard disk
110
. Further, the hard disk control application
560
copies the journal file stored in the hard disk
110
into the hard disk
140
in sequence.
Now, a procedure of retrieving electronic journal data will be described. First, a clerk inputs a retrieval condition using the clerk operating touch panel
300
and the clerk side LCD
310
. The inputted retrieval condition is notified to the machine control application
510
which then notifies it to the journal data control application
540
. The journal data control application
540
extracts, via the hard disk control application
560
, one matching the condition from the journal file A or B stored in the hard disk
110
and notifies the retrieval result to the machine control application
510
. The machine control application
510
displays the received retrieval result on the clerk side LCD
310
. Through this displaying, a cause of a trouble caused in the machine and a measure therefor or the like may be clarified to the clerk, and if necessary, the clerk may be instructed to call a service company or the like.
Now, a procedure of writing electronic journal data into the CD-R
180
will be described. The machine control application
510
checks a storage amount of the journal file A or B in the hard disk
110
. When the journal file A or B is detected to be full, the machine control application
510
displays on the clerk side LCD
310
to notify that a new CD-R
180
should be set. If the new CD-R
180
has already been set, this notification is not displayed. Further, when the journal file A or B is detected to be full, the machine control application
510
requests the journal data control application
540
to switch from the full journal file A or B to the other journal file B or A in the hard disk
110
. Thus, the hard disk control application
560
stores new electronic journal data received thereafter into the journal file B or A in the hard disk
110
. This ensures storage of new electronic journal data into the hard disk
110
while writing the full journal file into the CD-R
180
.
The clerk sets the new CD-R
180
in the CD-R drive
170
and requests the machine control application
510
to write the full journal file into the CD-R
180
using the clerk operating touch panel
300
and the clerk side LCD
310
. If the new CD-R
180
has already been set, this operation of the clerk is not required, either.
The machine control application
510
confirms via the CD-R control application
550
whether the CD-R
180
is set in the CD-R drive
170
. When it is set, the machine control application
510
demands the hard disk control application
560
to transfer the full journal file A or B. Then, after receipt of the full journal file, the machine control application
510
transfers it to the CD-R control application
550
and requests it to store the full journal file into the CD-R
180
.
The CD-R control application
550
stores the received journal file A or B into the CD-R
180
. After the full journal file A or B has been stored into the CD-R
180
, the hard disk control application
560
deletes the full journal file A or B or initializes it into a nonused state.
Other than the foregoing case wherein the machine control application
510
checks the storage amount of the journal file A or B to automatically implement storage into the CD-R
180
, there is also a case wherein the clerk inputs a command upon emergency so that storage into the CD-R
180
is carried out. Specifically, in this case, the clerk uses the clerk operating touch panel
300
and the clerk side LCD
310
to request the machine control application
510
to store the journal file A or B into the CD-R
180
.
In response to receipt of the request from the clerk, the machine control application
510
requests the hard disk control application
560
via the journal data control application
540
to switch from the journal file A or B to the journal file B or A. Thereafter, the machine control application
510
requests the CD-R control application
550
to store the journal file A or B, which is not being used, into the CD-R
180
.
The CD-R control application
550
stores the received journal file A or B into the CD-R
180
. After the journal file A or B has been stored into the CD-R
180
, the hard disk control application
560
deletes or initializes the journal file A or B.
After the journal file A or B has been stored as described above, the clerk removes the CD-R
180
from the CD-R drive
170
and prints a machine number and a serial number on the surface of the CD-R
180
. Then, the data stored in the CD-R
180
and other necessary data such as a storage date and a clerk in charge are inputted and stored in a data base system separately set for management. The clerk further preserves the CD-R
180
in a given keeping place. Instead of being printed on the surface of the CD-R
180
, the foregoing serial number may be recorded as a header such as a volume label of the CD-R
180
. Alternatively, during production of the CD-R
180
, the serial number may be recorded as a volume label in advance.
FIG. 5
is a flowchart showing the foregoing journal data writing procedure. First, a use-indicative flag of a journal file A is checked to confirm whether the journal file A is used (step S
101
). If the journal file A is not used (No at step S
101
), journal data is written into a journal file B (step S
102
). A subsequent procedure is the same as that represented by steps S
103
through S
110
.
If the journal file A is used (Yes at step S
101
), the journal data is written into the journal file A (step S
103
).
Then, it is detected whether the journal file A is full (step S
104
). If it is not full (No at step S
104
), the routine returns to step S
101
. On the other hand, if the file is full (Yes at step S
104
), switching from the journal file A to the journal file B is implemented (step S
105
) and a use-indicative flag of the journal file B is set (step S
106
).
Subsequently, a set flag of a CD-R
180
is checked to confirm whether the CD-R
180
is set (step S
107
). If the CD-R
180
is not set (No at step S
107
), the routine returns to step S
101
. On the other hand, if the CD-R
180
is set (Yes at step S
107
), the journal file A is written into the CD-R
180
(step S
108
).
Then, it is checked whether writing of the journal file A into the CD-R
180
has been finished (step S
109
). If not finished (No at step S
109
), the routine returns to step S
108
. On the other hand, if the storage has been finished (Yes at step S
109
), the journal file A is initialized (step S
110
). Then, the routine returns to step S
101
.
According to the foregoing first preferred embodiment, since the CD-R
180
into which writing is executed in a disk-at-once manner is used as a storage medium of electronic journal data, the truth guarantee is ensured with respect to the journal data stored in the CD-R
180
.
The journal files A and B are provided in the hard disk
110
and switching therebetween is carried out such that while reading one of the journal files A and B and writing it into the CD-R
180
, the other journal file receives new electronic journal data. Thus, even when journal data is written into the CD-R
180
whose write speed is low, sequentially generated journal data are received by the hard disk
110
into one of the journal files A and B so that reception of new electronic journal data can be independent of the writing into the CD-R
180
, thereby preventing an operation of the automatic tellers machine from being stopped.
Since the journal file A or B is initialized after storage thereof into the CD-R
180
has been finished, even if the storage of the journal file A or B into the CD-R
180
fails, the journal file A or B can remain in the hard disks
110
and
140
. Thus, the remaining journal file A or B can be read again from beginning and stored into another CD-R
180
. This allows highly reliable data storage.
The hard disks
110
and
140
for storing the same contents, i.e. the same journal files A and the same journal files B, are provided. Thus, journal data once received in the hard disk
110
is prevented from being lost before or during storage into the CD-R
180
due to disk or file crash. This arrangement, when combined with the foregoing arrangement wherein the new journal data can be received during storage of the journal file into the CD-R
180
, can achieve the data storage safety and the non-stoppage of the machine so as to further enhance the reliability.
In addition, the following advantages can be realized:
Since the CD-R
180
has a large storage capacity (maximum of 640MB) relative to the size thereof, the number of maintenance times can be reduced.
The CD-R
180
is extremely smaller in size as compared with the journal paper P when storing the same data amount, so that a keeping space of a warehouse or the like can be effectively used.
Since journal data is electronic data, retrieval of the journal data can be achieved using a computer.
Second Embodiment
FIG. 6
is a block diagram showing a software structure of a transaction record storing device including hard disks
110
and
140
and a CD-R
180
of an automatic tellers machine according to the second preferred embodiment of the present invention. The other structure of the automatic tellers machine not shown in
FIG. 6
is essentially the same as that of the foregoing first preferred embodiment. Thus, detailed explanation thereof will be omitted in the following description.
In
FIG. 6
, a hard disk control application
560
is provided with an address managing section
600
, and a CD-R control application
550
is provided with a medium managing section
700
. In this embodiment, data writing into the CD-R
180
is executed in a track-at-once or packet-write manner so that the CD-R
180
serves as a storage medium which keeps its data alteration record, i.e. wherein new data is writable while the stored data remains unchanged.
It is necessary in this embodiment that the capacity of each of the hard disks
110
and
140
be greater than the capacity of the CD-R
180
(maximum of 640MB). Specifically, in this embodiment, by way of precaution against failure of storage into the CD-R
180
, electronic journal data subjected to storage into the CD-R
180
(hereinafter also referred to as “original journal data”) is arranged to be maintained as minimum data in each of the hard disks
110
and
140
. The maximum data amount to be maintained as the original journal data is set to be equal to the maximum capacity of the CD-R
180
. Since each of the hard disks
110
and
140
further stores new electronic journal data, the storage capacity thereof should be greater than that of the CD-R
180
.
The address managing section
600
manages a next write pointer
610
, an output pointer
620
and an initial value pointer
630
.
The next write pointer
610
is a pointer for appointing a write start address when writing journal data generated per transaction into the hard disks
110
and
140
. After having reached the maximum address, the pointer
610
is updated to the minimum address.
The output pointer
620
is a pointer for appointing a read address in the hard disk
110
when storing journal data from the hard disk
110
into the CD-R
180
of the CD-R drive
170
.
The initial value pointer
630
is a pointer for appointing a first read address in the hard disk
110
of electronic journal data subjected to storage into the CD-R
180
. Even when the CD-R
180
is subjected to failure while writing electronic journal data thereinto, the intended data writing can be achieved by copying the journal data from an address appointed by the initial value pointer
630
to an address appointed by the output pointer
620
into a new CD-R
180
. When the CD-R
180
is detected to be full, the initial value pointer
630
is reset to appoint the same address as that of the output pointer
620
.
The medium managing section
700
comprises a medium number recognizing section
710
, a medium setting detecting section
720
and a medium information printing section
730
.
The medium number recognizing section
710
manages numbers of CD-R's
180
. Specifically, the medium number recognizing section
710
records a medium number (serial number) produced in the section
710
as a volume label of the CD-R
180
. Further, the medium number recognizing section
710
makes a check when the CD-R
180
is changed to new one before it becomes full, and indicates a medium number upon data retrieval.
The medium setting detecting section
720
confirms a setting state of the CD-R
180
into the CD-R drive
170
. Upon detecting nonloading of the CD-R
180
or loading of a wrong medium, the medium setting detecting section
720
commands the machine control application
510
to stop data storage into the CD-R
180
. This causes no influence to data storage into the hard disks
110
and
140
.
The medium information printing section
730
prints a machine number and a medium number (serial number) on the surface of a casing of the CD-R
180
.
As described before, the transaction data control application
500
edits electronic journal data with respect to a transaction established through a customer's operation of the customer operating touch panel
200
. Then the transaction data control application
500
sends the electronic journal data to the hard disk control application
560
via the machine control application
510
and the journal data control application
540
.
Then, as shown in
FIG. 7
, the electronic journal data is stored at a write start address Al in the hard disk
110
designated by the next write pointer
610
of the address managing section
600
. The electronic journal data is also stored into the hard disk
140
likewise. The write start address A is incremented as A
1
′, A
1
″—every time writing is finished.
On the other hand, when a write start address appointed by the next write pointer
610
has reached the maximum address, the next write start address is changed to the minimum address. Further, a write start address appointed by the next write pointer
610
is managed so as not to get ahead of a read address of the initial value pointer
630
. This is necessary for the following reason: In this embodiment, the original journal data from a read address appointed by the initial value pointer
630
to a read address appointed by the output pointer
620
is maintained so that, even upon failure of storage into the CD-R
180
, the original journal data still can be written into a new CD-R
180
. Thus, if the write start address appointed by the next write pointer
610
gets ahead of the read address of the initial value pointer
630
, overwriting on the original journal data is caused so that the original journal data can not be restored.
There is no particular limitation to the timing of writing electronic journal data of the hard disk
110
into the CD-R
180
. If the capacity of the hard disk
110
is far greater (>>) than the capacity of the CD-R
180
, writing of electronic journal data into the CD-R
180
may be carried out while reception of new electronic journal data is not so often or just before stoppage of the machine operation. In this embodiment, however, such writing is implemented when the storage amount of electronic journal data in the hard disk
110
not yet stored into the CD-R
180
reaches a predetermined value.
Upon performing such writing, the medium setting detecting section
720
confirms a setting state of the CD-R
180
relative to the CD-R drive
170
. It is assumed here that the CD-R
180
is set in the CD-R drive
170
. Then, the medium number recognizing section
710
records a medium number produced in the section
710
as a volume label of the CD-R
180
.
Then, upon starting reading of electronic journal data from the hard disk
110
, the address managing section
600
sets a first read address A
3
to the initial value pointer
630
as shown in FIG.
7
. As described above, this is for maintaining the original journal data from a read address appointed by the initial value pointer
630
to a read address appointed by the output pointer
620
so that, even upon failure of storage into the CD-R
180
, the original journal data still can be written into a new CD-R
180
. The read address A
3
is not changed until the CD-R
180
is detected to be full.
As shown in
FIG. 7
, following a read address A
2
appointed by the output pointer
620
, electronic journal data is read from the hard disk
110
in sequence and stored into the CD-R
180
. The read address A
2
is incremented as A
2
′, A
2
″—every time reading is executed.
The electronic journal data from the read address A
3
set to the initial value pointer
630
to the read address A
2
appointed by the output pointer
620
are maintained as they are until the storage amount of the electronic journal data in the CD-R
180
reaches the maximum capacity of the CD-R
180
(maximum of 640MB in this embodiment).
If the storage of the electronic journal data into the CD-R
180
is subjected to failure, the CD-R drive
170
sends a signal indicative of an occurrence of failure to the machine control application
510
which, in response to the signal, displays on the clerk side LCD
310
a message requiring a change of the CD-R
180
. When the medium setting detecting section
720
detects setting of a new CD-R
180
in the CD-R drive
170
by the clerk, the medium number recognizing section
710
records a new medium number as a volume label of the new CD-R
180
.
Then, the address managing section
600
again reads from beginning the electronic journal data from the read address A
3
set to the initial value pointer
630
to the read address A
2
appointed by the output pointer
620
and stores them into the new CD-R
180
.
As shown in
FIG. 8
, when the storage amount in the CD-R
180
reaches the maximum capacity thereof, the read address A
3
of the initial value pointer
630
is reset to coincide with the read address A
2
of the output pointer
620
from which the next storage into a new CD-R
180
is started. This allows a write start address A
1
of the next write pointer
610
to be set in an area where the original journal data is stored (area from the address A
3
to the address A
2
), so that new electronic journal data can be overwritten on the original journal data on that area.
FIG. 9
shows the state wherein the write start address A
1
appointed by the next write pointer
610
is set in the area where the original journal data is maintained.
When the CD-R
180
is detected to be full, the medium information printing section
730
of the medium managing section
700
prints a machine number and a medium number on the surface of a casing of the CD-R
180
. This allows easy selection from among the CD-R's
180
upon performing data retrieval later.
If there remain more electronic journal data to be stored into the CD-R
180
, the machine control application
510
displays on the clerk side LCD
310
a message requiring a new CD-R
180
.
When the medium setting detecting section
720
detects removal of the CD-R
180
from the CD-R drive
170
or setting of a new CD-R
180
before the previous CD-R
180
does not become full, the medium setting detecting section
720
prohibits writing by the CD-R drive
170
. For fear of breakage, it may be arranged to produce a pair of CD-R's
180
storing the identical data with each other.
According to the second preferred embodiment, since the CD-R
180
which keeps its data alteration record is used a storage medium of electronic journal data, the truth guarantee is ensured with respect to the journal data stored in the CD-R
180
.
In the foregoing first preferred embodiment, the journal files A and B are required for preventing an operation of the machine from being stopped during writing of electronic journal data into the CD-R
180
. On the other hand, in the second preferred embodiment, only the journal file A is required as shown in FIG.
6
. Specifically, in the second preferred embodiment, electronic journal data are read from the journal file A in sequence and written into the CD-R
180
while new electronic journal data is written into the journal file A, thereby to prevent an operation of the machine from being stopped. On the other hand, as in the foregoing first preferred embodiment, the hard disk
140
is used as a mirror disk of the hard disk
110
to prevent journal data once received in the hard disk
110
from being lost before or during storage into the CD-R
180
due to disk or file crash.
In the second preferred embodiment, electronic journal data in the hard disk
110
subjected to storage into the CD-R
180
are maintained as they are until the storage amount of the electronic journal data in the CD-R
180
reaches the maximum capacity of the CD-R
180
. Thus, even if the storage of the electronic journal data into the CD-R
180
is subjected to failure, the original journal data are maintained as they are in the hard disk
110
. Accordingly, the maintained original journal data can be read again from beginning and stored into another CD-R
180
, thereby ensuring reliable storage of the electronic journal data. On the other hand, when the storage into the CD-R
180
is successful, an area in the hard disk
110
storing the original journal data subjected to the storage into the CD-R
180
is released to allow new journal data to be received therein.
In the second preferred embodiment, it may be arranged that every time a write amount of electronic journal data into the CD-R
180
reaches a predetermined value, the read address A
3
of the initial value pointer
630
is reset to coincide with the read address A
2
of the output pointer
620
from which the next writing into the CD-R
180
is started. With this arrangement, every time a write amount of the electronic journal data into the CD-R
180
reaches the predetermined value, a corresponding area from the read address A
3
to the read address A
2
in the hard disk
110
is released for receiving new electronic journal data. Thus, the storage capacity of the hard disk
110
can be used more effectively.
While the present invention has been described in terms of the preferred embodiments, the invention is not to be limited thereto, but can be embodied in various ways without departing from the principle of the invention as defined in the appended claims.
