Abstract

PURPOSE:To prevent the erroneous recording due to wrong original data by comparing the card data read in the preceding time with the card data to be written this time and checking both data. CONSTITUTION:A card store part 13 loads many unprocessed cards 12 and is kept in a store holding state. A magnetic writing head 16 writes the initialized card data onto a card 12 drawn out of a lower draw-out part 18 on a card transfer path 15. Then a magnetic reading head 17 reads the card data and the card 12 is led and stored in a card stocker part 14. When the card data are repetitively written onto the card 12, the card data read out of the precedent card 12 with the card data to be written this time for decision of the propriety of the latter card data. Thus the transformation of the original data or a data editing error can be detected and therefore it is possible to prevent such a defective case where a card recorded wrong is issued as it is.

The present invention aims to provide a card data checking device that can reliably prevent erroneous recording due to errors in the original data by comparing and checking the card data read previously and the card data to be written this time. .

(d) Means for Solving Problems This invention is a card data checking device that writes the same card data to a plurality of cards and reads and confirms the data, and the card data read from the previous card and the card data read from the previous card. This is a card data checking device equipped with a comparison/determination means for comparing and determining the card data of the current card.

(E) Effect of the Invention According to the present invention, the comparison and determination means compares and determines the card data read from the previous card and the card data to be written to the card this time, and determines whether or not the data written this time is appropriate. .

(f) Effect of the invention That is, when the previous card data and the current card data are different, it indicates that the current written card data is an error, and this error is a garbled version of the original setting data.
Or, since it indicates that an error has occurred in data editing, such data errors can also be discovered.

Therefore, the initialized card data is successively compared and checked each time the card is recorded, and data management performance is reliable and highly reliable data processing can be obtained.

Particularly when a large number of cards are issued, stable data processing can be performed because the accuracy of judgment with card data recorded on each card is accurate.

(g) Examples An embodiment of the present invention will be described in detail below based on the drawings.

The drawing shows a card data checking device installed in a card issuing machine that issues prepaid cards, etc. In FIG. 13, a card stocker section 14 for storing processed cards, a card transport path 15 connecting these, a write magnetic head 16 disposed from the starting end of this card transport path 15, and a read magnetic head 17. It consists of

The above-mentioned card storage section 13 stores a large number of unprocessed cards 12.
.
Supply to 5.

Then, the write magnetic head 16 on the card conveyance path 15 writes card data such as the initialized amount data onto the drawn-out card 12, and then the written data is read by the reading magnetic head 17. After checking,
It is provided so as to be guided to the card stocker section 14 and stored.

In this case, when a defective card occurs, the sorting plate 19 provided at the front stage of the card stocker section 14 is operated to control the conveyance of the defective card to the card collection section 20 side.

FIG. 2 shows a control circuit block diagram of the card data checking device, in which the CPU 21 controls each circuit device according to a program stored in the ROM 22, and stores the necessary data in the RAM 23 in an input/output manner.

The input key 24 is the input key for each person using the keyboard.
24, the card data to be initially registered is input and set, such as the issuing institution code, amount, card number, issue date, machine number, etc.

The feeding motor M1 drives the feeding section 18 to control feeding out of the cards 12 one by one from the card storage section 13 to the card transport path 15.

The conveyance motor M2 drives the conveyance belt 15a and conveyance rollers 15b that constitute the card conveyance path 15 to nip and convey the card 12 fed out from the card storage section 13, and each magnetic head 16 on the conveyance path 15. After passing through the data processing position 17, the card is held and conveyed to the card stocker section 14 or the card collection section 20 at the subsequent stage.

The RAM 23 mentioned above is provided with various memory areas shown in FIG.

That is, the input memory mO stores the data set by the input key 24.

The first memory ml stores edited card data for writing to the card via the write magnetic head 16 based on the above-mentioned setting data.

The second memory m2 reads card data written on the card and stores the card data read through the magnetic head 17.

The comparison pattern memory mp stores previously read card data as a comparison target for card data to be written this time. However, at the initial stage of card data recording (the first time), the data in the input memory mO is stored, and thereafter, the memory is updated with the read cart data each time it is read.

The processing operation of the card data checking device 11 configured as described above will be explained with reference to the flowchart of FIG. 4.

First, the clerk inputs and sets the necessary card data such as the issuing institution code, amount, card number, date of issue, and machine number to be recorded on the card using the input key 24 on the keyboard (first step nl). , the CPU 21 stores the input card data in the input memory mO, and stores this input memory mO in the comparison pattern memory mp as the first comparison target (second step n2).

Next, the write data from the input memory mO is edited and stored in the first memory m1 as the current write data, and the data stored in the first memory ff11 and the data in the comparison pattern memory mp to be written to this card are Compare and check, and if they do not match, it is determined that it is a data editing error and error processing is performed (second to fourth steps n2 to
n4), if they match, it is determined that the data editing is appropriate and the writing process is executed to the first card via the write magnetic head 16 (fifth step n5).

Next, read the written card data and use the magnetic head 17.
This read card data is stored in the second memory
(sixth step n6).

Next, the current written card data in the first memory box 1 and the current read card data in the second memory m2 are compared and checked, and if they do not match, a writing error is determined and error processing is performed (seventh step n7). , if they match, it is determined that the recording process is appropriate and the second memory m2
The read card data is stored in the comparison pattern memory l1jp as a target for the next card data comparison (eighth step n8).

When it is determined that there are multiple cards to be written to (9th step n9), the above-mentioned third step n9 is performed.
Skipping to step 3, the above-described card writing process is repeatedly executed. In the writing process for the second and subsequent sheets, the fourth
The comparison and determination process in step n4 is a comparison between the card data read from the previously issued cart and the card data to be written this time.

If the previous card data and the current card data are different in the above comparison judgment, this indicates that the data in the input memory mO or the first memory m1 is garbled, indicating that the current card data is an error. The issue will be canceled and an error will be handled.

As mentioned above, by comparing and checking the previous and current card data, you can discover whether the original data is garbled or an error has occurred in the data editing, and you can continue to record the data incorrectly and issue the cart. This can be prevented. Therefore, cart data management performance is improved and highly reliable data processing can be obtained. Particularly, when a large number of cards are issued, stable data processing can be carried out because the accuracy of the cart identification recorded for each card is accurate.

In the correspondence between this invention and the configuration of the above-mentioned embodiment, the comparison and determination means of this invention is the fourth one of the CPU 21 of the embodiment.
Although it corresponds to the process of step n4, the present invention is not limited to the configuration of the above-described embodiment.
