Abstract

PURPOSE:To prevent injustice without erasing the value information of a card by making the card into the card in course of processing after recording personal identification information when it is found that the personal identification information is not recorded on the magnetic card, and controlling a selling operation by a recorded monetary value, and erasing the personal identification information when sale is finished. CONSTITUTION:When the magnetic card is inserted, a card processing device 9 reads stored card information and outputs it to a CPU 1. In the CPU 1, a deciding means decides whether the personal identification information is recorded on the card or not, and if recorded, a return controlling means controls the return of the inserted card. On the other hand, if the personal identification information is not recorded, this inserted card is mode to be the card in course of processing, and a first processing means records the personal identification information, and a sale controlling means gives a control signal to a selling device 7 on the basis of the monetary value recorded on this card in course of processing, and controls the selling operation. When the sale is finished, a second processing means erases the personal identification information, and this card is returned. Thus, even if the card is pulled back by a dishonest act, the amount of money the card has originally can be secured.

Description

Detailed Description of the Invention (a) Industrial Application Field The present invention reads the monetary value stored in a magnetic card when it is inserted, and sells products according to the 4i monetary value. The present invention relates to a card-type vending machine in which the remaining amount obtained by subtracting the sales amount from the i-sen value is written on the magnetic card as a new monetary value and returned.

(b) Conventional technology Card-type vending machines read value information from the card and retain it internally, and if the card is fraudulently withdrawn, the card will have a value subtracted according to the product sold. There is a problem where information is not recorded and products are sold for free.

In order to solve these drawbacks, Utility Model Publication No. 63-2452
Publication No. 1 describes that after reading from a card, the value information is temporarily set to zero or invalid data to deal with the above-mentioned fraud.

(c) Problems to be solved by the invention However, in Nis's conventional technology, changing the value information to zero or invalid data means erasing the original value of the card. There is a drawback that it is too harsh even as a compensation. Moreover, if the card is withdrawn without intending to commit fraud, or if the card is returned due to mechanical failure, the card amount cannot be compensated, which poses a serious problem.

In summary, the present invention provides a card-type vending machine that can reliably prevent fraud without deleting card value information.

(d) Means for Solving the Problems In order to solve the problem L, the card-type vending machine according to the present invention determines whether identification information is recorded on the magnetic card when a magnetic card is inserted. a means for determining,
return control means for controlling return of the magnetic card when the determination means determines that the identification information is recorded on the magnetic card; and return control means for controlling return of the magnetic card when the determination means determines that the identification information is recorded on the magnetic card; a first processing means that records the identification information on the magnetic card to make it a processing card; and a sales control means that controls a sales operation according to the monetary value recorded on the processing card. , and a second processing means for erasing the identification information upon discontinuation of sales.

(e) Effect When a card is inserted into the vending machine, the determining means determines whether identification information is recorded on the card. If the identification information is recorded, the return control means controls the return of the inserted card. On the other hand, if no identification information is recorded, this inserted card is treated as the card currently being processed, and the 12th
- The embedded means records identification information. The sales control means controls the sales activity according to the monetary value recorded on the card during this processing. When the sale ends, the second processing means erases the identification information and the card is returned.

(F) Embodiment FIG. 1 shows the circuit configuration of an embodiment of the present invention in a block diagram, where 1 is CP[J, 2 is ROM, 3 is RAM, 4 is
teeth! , /O interface, and these are connected by an address bus 5 and a data bus 6. Card processing device9. The vending device 71 selection device c8 is connected to the CPU 1 via the I'0 interface 1 and -C13;
CP[Jl controls these operations based on the program stored in the ROM2. When a magnetic card is inserted, the card processing device 9 reads the card information stored therein, outputs it to the CPUI, and records the card information output to the CPUI. The selection device 8 includes a plurality of selection switches corresponding to the types of products to be sold, and outputs a predetermined selection signal in response to a product selection operation by customer a. When the CPU 1 determines that the product indicated by the selection signal can be sold for the amount on the card, the CPU 1 provides a control signal to the sales device 7 to control the sales operation of the product.

As shown in FIG. 2, the magnetic stripe section 11 of the card 10 contains specific data 12 to distinguish it from cards of other systems, an operator code 13°, and amount data 14 indicating amount information held by the card. is recorded1
The specific data in this example consists of four characters "TSEC". When this data changes to "TSeC", the identification information wi15 indicates that the card is being buried in the evening.
becomes.

The operation will be described below with reference to the flowchart of FIG. 3, where this "TSeC" is referred to as data being processed.

First, when a card is inserted in step S1, the next step is step S2.
The card information read by the reader/writer 9A in step RA is stored in M3. In step 83, it is determined whether the card information includes data being processed. In case of normal cart, 1i specific data, i.e. “TSEC
” is recorded, the processing of CPU 1 proceeds to step S4. However, if the data being processed is set, the process proceeds to step S14, and this card is returned.

In the S4 step, the specific data "TSEC" among the card information stored in the RAM 3 is converted to TSeC.Then, in the S5 step, this card information is written to the card, and as a result, the data being processed is recorded on the card. It means that it was done.

In the card information recorded at this time, only the character E has been changed to e, and other information such as the operator code and amount data has not changed. It is determined whether the product can be sold at the amount indicated by the amount data. And if it is possible to sell it, S9 Ste! However, if the card amount is insufficient and the product cannot be sold, the process advances to step S7.

When processing the S7 steno knob, CP[JI determines whether the card amount is 0 yen or not, and if it is 0 yen, it proceeds to step 812, and if it is other than 0 yen, it proceeds to step 88, and the CPU
i performs card addition processing.

Then, when it becomes possible to sell the product using the card at the additional V port, the process advances to step S9.

In step S9, the CPU performs a sales operation and sends out the product selected by the customer, and calculates change in the next step S10. And in the next S11 stencil,
In order to write this change amount on the card, RA
Rewrite the amount data of the card information stored in M3. Subsequently, in step S12, RA, M3
Among the card information stored in the card information, “TSeC” is
EC" and memorize it. As a result, the data being processed is cleared and the specific data is set in the card information. Then, in the 5N3 step, the RAM
The card information of step 3 is read out and recorded on the card, and the card is returned in the next step 314.

In addition, if the card cannot be sold because the card amount is 0 yen, the process starts from step S7 and proceeds to step 812, and the card information stored in R, AM 3 is changed to "
TSeC" is converted to TSEC" and stored, and this card information is recorded on the card in step 513. Therefore, when a card with a value of 0 yen is inserted, some processing data is written, but since it cannot be sold for 0 yen, the card is returned after the processing data is cleared.

In the above operation, the card amount is read.
If the card is withdrawn due to fraud, the processing data, which is identification information, is still set on the card, so even if a new card is inserted, it will be returned.

(]・) Effects of the Invention According to the present invention, an effective card-type vending machine is provided in order to guarantee the original amount of money on the card even if the card is withdrawn due to fraud.

Therefore, once a card has been inserted, it may be returned due to malfunction or other reasons other than intentional! Customers will not be inconvenienced if
