Abstract

PURPOSE:To surely prevent injustice by breaking card data when the unjust pull-back of a card is detected. CONSTITUTION:The recorded data is read while the card is taken in by a carrying device 6. Then, a deciding means decides whether the read data is valid or not, and if invalid, a return controlling means controls the return of the card, and if valid, it makes a sale within the range of a monetary value shown by the data possible. Then, when plural sensors SE1 to SE3 generate card detection outputs in turn while the carrying device 6 is kept in a non-operating state, a processing means records invalid data on the card. Thus, the recorded data of the card pulled back unjustly becomes invalid, and when this card is inserted next time, it is returned.

Description

Detailed Description of the Invention (a) Industrial Application Field The present invention is a card-type vending machine that, when a magnetic card is inserted, sells the desired product based on the monetary value stored therein. Regarding.

(b) The card-type vending machine according to the conventional technology is disclosed in Japanese Patent Application Laid-Open No. 61-28399.
As disclosed in Publication No. 5, when the data recorded on the inserted card is read and the card is retained internally and a sales operation is performed, the money contained in this data is The remaining amount after subtracting the sales amount from the original value is written as a new monetary value on a magnetic card and returned.

(c) Problems to be solved by the invention However, if the card is fraudulently withdrawn while data is being read and retained from the card, the fLff value subtracted according to the sold product will still be recorded on the card. There is a problem where products are sold for free because they are not prepared.

[Second] The present invention provides a card-type vending machine that can reliably prevent fraud by destroying card data when it detects fraudulent withdrawal of a card.

(d) Means for Solving the Problems In order to solve the above problems, the card-type vending machine according to the present invention includes a plurality of sensors sequentially arranged along the card conveyance direction, and a plurality of sensors arranged in sequence when the conveyance device is inactive. processing means for recording invalid data on the card when the sensor sequentially generates a card detection output in the state; and determining means for determining whether the data recorded on the magnetic card is valid when the magnetic card is inserted. and return control means for controlling return of the magnetic card when the determination means determines that the recorded data on the magnetic card is invalid.

(e) Effect When a card is inserted into the vending machine, the conveyance device is driven,
While the card is being loaded, the data stored on it is read. The determining means then determines whether the read data is valid, and if it is invalid, the return control means controls the return of the inserted card. On the other hand, if the data is valid, sales can be made within the monetary value indicated by this data. When the plurality of sensors sequentially generate card detection outputs while the transport device is inactive, the processing means records invalid data on the card. Therefore, the recorded data of the card that has been illegally withdrawn is invalid, and the next time this card is inserted, it will be returned.

(F) Embodiment FIG. 1 shows a card processing device 29, in which an insertion slot 1 for receiving a card inside is provided in the upper part in the horizontal direction; It is connected to a conveying path 3 through a bend 2 for vertically converting the card. This conveyance path 3 consists of a set of fixed plate 4 and movable plate 5.
It is formed so as to guide the card downward. The conveying path 3 is provided with a conveying device 6 for vertically conveying the card.
A, 8B, pulleys 9A, 9B, pulley 10A, IOB, and belt 11. Each pulley is rotatably supported by a fixed plate 4 or a movable plate 5,
Further, the belt 11 is stretched around pulleys 7A, 8A, 9A, and IOA.

Such a conveying device 6 is equipped with a motor I2 capable of forward and reverse rotation.
The rotational force is transmitted via the belt 13 to a variable speed pulley 19 mounted coaxially with the pulley 8A, thereby driving the pulley 8A. In the transport path 3, sensors SE, SE2, . SE3 are arranged in sequence, and the interval between the sensors is set to be smaller than the dimension of the card in the operator's direction. Such sensors SE, ,SE
, , SE, the cards in the transport path 3 are detected by one of the sensors. Also, in the middle of the conveyance path 3, there is a sensor SE, and a magnetic head 16 and a pressure roller 17 are located at the same position.
A reader/writer 18 consisting of the following is provided. The reader/writer 18 reads the recorded information on the card passing through the transport path 3 and records the information on the card. Pressing roller 1
7 is for pressing the card passing through the general transport path 3 against the magnetic head 6.

As shown in FIG. 2, the magnetic stripe section 20 of the card contains specific data 30 to distinguish it from other card systems.
or operator code 31. Amount data 32 indicating the monetary value of the card is recorded. The specific data in this example is composed of four characters "T5EC".

Furthermore, if the card is pulled back illegally, invalid data of all "1" or "O" is recorded in this magnetic stripe section 20.

FIG. 3 shows the circuit WR configuration of one embodiment for controlling this vending machine in blocks, in which 21 is a CPU;
2 is a ROM, 23 is a RAM, 24 is an I10 interface, and these are an address bus 25 and a data bus 26.
It is connected at

Power/hard processing device 29. The sales device 271 selection device 28 is connected to the CPU 21 via the 110 interface 24, and the CPU 21 controls these operations based on a program stored in the ROM 22. The card processing device 29 receives a read/write signal R/ from the CPU 21.
According to W, data is read or written to the magnetic card 16, and the data to be recorded on the card is introduced from the CPU 21. The card processing device 29 includes a CPU 21
The motor 12 of the transport device 7i6 is rotated in the forward and reverse directions by the take-in signal A or the return signal B introduced from the transport device 7i6.

When the motor 12 rotates in the normal direction, the transport device 6 transports the card so as to deposit it, and when the motor 12 rotates in the reverse direction, the transport device 6 transports the card so as to return it. The selection device 28 includes a plurality of selection switches depending on the type of product to be sold, and outputs a predetermined selection signal to the CPU 21 in response to a selection operation by a customer.

The operation will be explained with reference to the flowchart in FIG.

First, in step Sl, the CPU 21 determines whether the card is pulled back. This pullback is the sensor SE.

After the sensor SE detects the card and enters ONL, the sensor SE also detects the card and determines whether it is ONL, and if there is no illegal withdrawal, the process proceeds to the next step 83.

In this S3 step, the CPU 21 detects the sensor SE.

By detecting the card and determining whether it is ONL,
Determine whether a card has been inserted. If no card is inserted, the processing of the CPU 21 returns to step S1, but
Proceed to the final step S5 where the card is inserted.

In step S5, the CPU 21 drives the transport device 6 to take in the inserted card, and also causes the card processing device 29 to take in the inserted card.
A read signal is given to the magnetic head 16, and the card information is read by the magnetic head 16. Then, in the next step S7, the card information read by the card processing device 29 is written in the RAM 23.
After t, the process advances to step S9.

In step S9, the CPU 21 determines whether the inserted card is a valid card from the read card information. This determination is made by determining whether the card information includes correct specific data and operator code. If the specific data or operator code is incorrect, or if the recorded data on the card is all 0, the process of the CPU 21 is performed in S3.
Proceeding to step 3, the CPU 21 drives the transport device 6 in the opposite direction to return the card.

51. When processing 1 step knob, the CPU 21 determines whether the card amount is O yen ff1J L, S31 if it is O yen
Proceed to step. If the value is other than 0 yen, the process proceeds to step 313, where the CPU 20 stops the conveyance device 6 and controls the holding of the card. The card is therefore held within the transport device 6 in preparation for the vending operation.

At the 515 step, as in the S3 step, the sensor SE,
By determining whether the card is ON or not, it is possible to check whether the card is being withdrawn illegally.

If there is no illegal withdrawal of the card, 517 steps are processed. In step S17, a sales operation is performed based on the card amount. When a product that can be sold for the card amount is selected, the CPU 21 gives a control signal to the sales device 27 to send out the product selected by the customer. . Then, in step S19, the CPU 21 checks whether the card is withdrawn by determining whether the sensor SE is ONL, and then calculates the change in step S21.

Then, in step S23, CP [J21 is the sensor SE,
By determining whether the card is ON or not, it is possible to check for illegal withdrawal of the card.

If there is no unauthorized withdrawal of the card, first in step S25, the CPU 21 rewrites the amount data of the card information stored in the RAM 23 into the amount of change so that the calculated change is the amount to be written on the card. Followed by S
In step 27, the card information with the rewritten amount data is given to the card processing device 29 along with a write signal,
This card information is recorded on the card by driving the transport device 6.

Then, in step S29, the CPU 21 determines whether the change is O yen or not, and if it is not 0 yen, the CPU 21 returns the card in step S3.
This is a 3-step process. Therefore, the card with the updated remaining amount recorded has been returned to the customer. On the other hand, if the change is 0 yen, the CPU 21 proceeds to step S31 and drives the conveyance device 6 to take in more cards.

Sl,,515. S19. When an illegal withdrawal of the card is detected in each step of S23 and the process proceeds to step S35, the CPU 21 provides invalid data consisting of information of all "1" or "O" to the card processing device 29. As a result, invalid data is recorded on the card that is moved by pulling back. And CPU21 with S37 stem
reads/writes by the magnetic node 16 are suspended until all sensors no longer detect the card. In this way, even if a card with invalid data recorded by pulling it back is inserted into a vending machine next time, it will be determined as an invalid card and cannot be used, thereby preventing fraud.

(g) Effect of the invention According to the invention, when a card is withdrawn due to fraud,
Since invalid data is recorded on this card, it cannot be used again. Therefore, since the card is invalidated only if the card is returned due to fraud, the card data will not be destroyed if the card is returned due to malfunction or the like, thereby providing a highly reliable card-type vending machine.
