Further, in this case, when a card with defective data is generated, the distribution plate 19 provided in the preceding stage of the card stocker unit 14 is distributed to control the conveyance of the defective card to the card collection unit 20 side.

FIG. 2 shows a block diagram of a control circuit of the card data check device. The CPU 21 controls each circuit device in accordance with a program stored in the ROM 22 and stores necessary data in the RAM 23 so that the data can be input / output.

The input key 24 is a key input by the input configurator on the keyboard.
The card data to be initially registered is input and set via 24 ..., For example, the issuing agency code, the amount of money, the card number, the issuing date, the machine number, etc. are input.

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

The transport motor M2 drives the transport belt 15a and the transport roller 15b that constitute the card transport path 15 to drive the card storage unit 1
The card 12 delivered from the card is sandwiched and conveyed, and after passing through the data processing positions of the magnetic heads 16 and 17 on the conveying path 15, the card stocker unit 14 or the card collecting unit 20 in the subsequent stage is conveyed.
Hold and transport to.

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

That is, the input memory m0 stores the data set by the input key 24.

The first memory m1 stores the 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 stores the card data read by the magnetic head 17 for reading the card data written on the card.

The comparison pattern memory mp stores the previously read card data as a comparison target of the card data to be written this time. However, at the beginning of card data recording (first time)
Stores the data in the input memory m0 and thereafter updates the memory with the read card data every time the data is read.

The processing operation of the card data check device 11 thus configured will be described with reference to the flowchart of FIG.

First, the clerk inputs and sets necessary data as card data such as issuing agency code, amount of money, card number, issue date, machine number, etc. to be recorded on the card through the input keys 24 of the keyboard (first step n1), The CPU 21 stores this input-operated card data in the input memory m0, and also stores this input memory m0 in the comparison pattern memory mp as the first comparison target (second step n2).

Next, the write data from the input memory m0 is edited and stored in the first memory m1 as the current write data, and the data of the comparison pattern memory mp of the stored data of the first memory m1 to be written to this card is also written. Compare and check, if they do not match, it is judged as a data editing error and error processing is performed (2nd to 4th steps n2 to n4). If they match, the data editing is judged to be proper and the first card Then, the writing process is executed via the writing magnetic head 16 (fifth step n5).
