A readout circuit 6 and a product selection button 11 are connected to the input port 104 . The readout circuit 6 is.

As will be described later, when inserting the magnetic card l into the vending machine, first and second amount data DI, D2, judgment data for determining whether the card is genuine or not, and an error signal in the event of a recording error are input. Give port 104, magnetic card 1
When the vending machine is removed from the vending machine, written data of the total amount spent up to the sale is given to the input capo 104. The product selection button 11 supplies product selection data to the input port 104 in accordance with the purchaser's product selection.

A writing circuit 51, a display device 12, and a product dispensing device 13 are connected to the output port 105. The write circuit 5 is given a command to write the total amount spent up to the sale when the magnetic card l is removed from the vending machine, and a command to write an error signal in the event that a recording error occurs. 0 display device 1
2 is given display commands such as card insertion, product selection, and card removal. A product delivery command is given to the product delivery device 13.

Next, the operation of the above configuration will be explained using the flowchart shown in FIG.

In the state of waiting for card acceptance, a card insertion instruction is issued to the display device 12 (step 20), and the display device 12 displays a message to that effect. When a card is inserted according to this display, the card is If there is an error in the first and second amount data DI, D2 of the card 1, judgment data for determining the authenticity of the card, and recording, an error signal is read through the reading circuit 6 (step 21).
, the validity of the card used is determined based on the determination data (step 22), and the presence or absence of an error signal is determined (step 23). This is provided to exclude the use of cards that have been sold or used in other sales. The error signal is from the card
If the amount of money is not written correctly for some reason, it is written on the card l in order to recognize that there was an error in the writing.

If the card is valid and there is no error signal, proceed to step 24, where the recorded amount D1. The magnitude of D2 is determined. If the first amount data D1 is larger than the second amount data D2 (CD+>D2), then R
The amount D2 is D in the data area Ds prepared in AM103.
Gold ill D+ is written to L (step 25)
, if the amount D+ <the amount D2, the amount DI is written in Ds and the amount D2 is written in DL (step 26). If the amount DI=the amount D2, that is, when the card is first used, DI = l) 2 = Q, and either can be entered as DS or DL. In this example, the amount DI is in Ds,
Amount D2 is entered into DL (Step 7, Step 27).

Next, an instruction to select a purchased product is given to the display device 12 (
In step 28), a message to that effect is displayed on the display device 12, and the process waits for the product price data D to be accepted. When the purchaser selects a purchased product using the product selection button 11, the price data D corresponding to the product and the larger amount DL obtained in step 25, 26, or 27 are extracted and added. (step 29),
The resulting additional amount (Dt +D) is temporarily stored. Next, the process moves to step 30, where an instruction to remove the card is given to the display device 12, and a message to that effect is displayed on the display device 12.

If the purchaser removes card 1 according to the card removal display, at the time of this removal, Ds
The amount entered in DI or step 2 instead of D2
A write output is given to the write circuit 5 so that the calculated amount (DI +D) of 9 is written to the card (step 3).
1). Therefore, for example, amount DI = DS, money 1iiD
If 2=DL, an additional amount 111 (Dz+D) is written in place of the amount D1, which becomes the new amount DI', and the amount D2 is left as is. In the next sale that follows, the amount D2 = DS and the amount D1° = DL.If the product price in this sale is D, then the additional amount (ol'+o') is written in place of the amount D2, The amount D1° is left as is.

When the card is removed, the reading circuit 6 reads the additional amount (DL + D) written on the card in step 31, and the read content and the additional amount (Dt + D) temporarily stored in step 29 are read out. ) is determined (step 32.33), which results in
If the two match and the additional amount (DL + D) is correctly written, a command to dispense the corresponding product is given to the product dispensing device 13 (step 34), and the product is dispensed from the vending machine.

Step? If it is determined in step 2 that the card used is inappropriate, the card inappropriateness processing routine 35 is called, and the display device @12
A message indicating that the card is inappropriate is displayed, and the eye movement stops.

If it is determined in step 33 that there is an error in writing the additional amount, an error signal is written via the writing circuit 5 when the card is removed as described above (step 3
6) 0 Card re-insertion information is then provided to the display device 12 (step 37) to prompt reinsertion of the card. When the card is reinserted, steps 21 and 22 are followed by step 23 and step 38 is entered. In step 38, enter the amount without an error signal in DL, and enter the amount with an error signal in Ds. For example, the amount DI
=l)5, the amount D2 =DL, and the additional amount (D2
+D) is written instead of the amount DI, and if a writing error occurs at this time, DL is set as D2 without a writing error, and the amount D1 with a writing error is set as DS. As a result, subsequent sales operations are performed based on the amount for which no writing error occurred, and a new additional amount is written in step 31 for the amount in which the writing error occurred.

As a result of such sales, the amount DI of card 1.

The cumulative amount after purchasing the product is recorded on one side of D2, and the cumulative amount before the final use of the card is left on the other side. Settlement is performed by reading the cumulative amount recorded on one side.
