Description

[Detailed description of the invention] (a) Industrial application field The present invention reads value information recorded on a card,
The present invention relates to a card processing device that records updated value information on a card after a transaction according to the value information and then returns the card.

(B) Prior Art As disclosed in Japanese Patent Laid-Open No. 61-283995, such a card processing device reads the information recorded on the inserted card and then retains the card inside. , the card information is updated and recorded based on transaction processing using the card information and returned.

(c) Problems to be Solved by the Invention However, in conventional card processing devices, if the card is fraudulently withdrawn while the information is read from the card and retained internally, the card will not be processed according to the transaction. The updated information subtracted by the card will not be recorded, and there is a risk that this card can be misused in the next transaction.

Therefore, in order to prevent such fraud, the present invention
To provide a card processing device which temporarily sets the value of the card to substantially "0" when a transaction operation is permitted, and records original update information on the card instead of "0" after the transaction is completed.

(d) Means for Solving the Problems In order to solve the above problems, the card processing device of the present invention is provided with at least two recording units that can read and write to the card, and when the card is inserted. a reading means for reading the value information completely recorded in the first recording part; a first writing means for writing the value information read by the reading means into the second recording part; a second writing means for writing value information of substantially "0" into the first recording part after the first recording part;
and a holding means for holding the input card written by each of the second writing means, and a holding means for holding the inserted card written by each of the second writing means, and a holding means for holding the inserted card written by each of the second writing means, and the updated value information after a predetermined transaction is made based on the value information read by the reading means. The present invention includes a third writing means for writing into the first recording section in place of the value information of "', and a return means for returning the card in which the updated value information has been recorded to the inserter.

(e) When the effect card is inserted, the reading means reads the value information recorded in the first storage section of the card, and the first writing means writes the read value information to the second storage section of the card. At the same time, the value information of "0" is stored in the first recording section in the second recording section.
Write using a writing method. Thereafter, the inserted card is held by the holding means. In this state, the service machine connected to the card processing device performs a service based on the value information, and outputs updated value information subtracted according to the service to the card processing device. Then, the card processing device uses the third writing means to rewrite the value information in the first recording section of the card from substantially "O" to updated value information, and then returns the card using the return means.

Therefore, even if the card held in the holding means is illegally withdrawn, the value information of this card will be 'O', making it impossible to use it again.

(f) Example Examples will be described below with reference to the drawings.

FIG. 1 shows a card processing device, in which an insertion slot (1) for receiving a card is provided in the upper part in a horizontal direction.

The insertion slot (1) passes through a bending part (2) for converting a horizontally inserted card into a vertical direction, and then leads to a conveyance path (3).
)It is connected to the. This conveyance path (3) is formed by a fixed plate (4) and a movable plate (5) to guide the card vertically downward. The conveying path (3) is provided with a conveying device (6) for vertically conveying the card, and this conveying device (6) consists of a pair of opposing pulleys (7A>(7B), 8A) (8B),
(9A) (9B), (IOA>(IOB)) and a belt (11). Each pulley is rotatably supported by a fixed plate (4) or a movable plate (5). , and the belt (11) has pulleys (7A) (8A)
(9A) (IOA) is suspended. In such a conveying device (6), the rotational force of a motor (12) capable of forward and reverse rotation is transmitted via a belt (13) to a variable speed pulley (13) installed coaxially with a pulley (8A). drive The rotary encoder (14) shown in FIG. 2 includes a pulley (15) rotated by a belt (13), and periodically outputs encoder pulses as the pulley (15) rotates. Sensors (A), (B), and (C) each consisting of a set of light emitting elements and light receiving elements are sequentially arranged in the transport path (3) according to the direction of movement of the card.
The spacing between the sensors is set to be smaller than the longitudinal dimension of the card. Such sensors (A), (B),
With the arrangement shown in (C), a card in the transport path (3) is detected by one of the sensors. In addition, in the middle of the conveyance path (3), a card reading/writing device (comprised of a magnetic head (16) and a pressure roller (17) located at the same position as the sensor (B) (
18) is provided. The magnetic head (16) reads information on the card passing through the conveyance path (3) and writes updated data to this card, and the pressing roller (17) magnetically presses the card (16) through the conveyance path (3). ).

Value information is recorded on the card's magnetic stripe ('') along with card-specific information such as identification information to distinguish it from other card systems, operator hood or destination code. , there is value information that the card currently has and value information that it had when the previous processing was completed, and the magnetic stripe section ('') has these two types of value information as shown in Figure 2. A recording section ("A") ("B) for recording value information is set. The recording section ("C") of the magnetic stripe section (") is a security area for recording the above-mentioned identification information and unique information of the card. - FIG. 2 shows a control block diagram, and (20) is a CPU that operates according to a preprogrammed control procedure, and is internally equipped with registers R1 to R4. (21) is
The magnetic head (16) responds to the read start signal R5T.
A reading circuit (22) reads the card information and outputs it to the CPU (20), and in response to the write start signal WST, the reading circuit (22) reads the write data given by the CPU (20) and outputs it to the card using the magnetic head (16). This is a write circuit that writes to (
23) is a service machine, such as a vending machine, which provides a predetermined service to a card inserter based on the value information of the card inserted into the card processing device, and the card processing device is built into the service machine. And the service machine (2
3) is connected to the CPU (
20), and whether or not the card processing device performs a card processing operation is controlled by the service device (23).

The operation of the card processing device will be described below with reference to the flowcharts of FIGS. 3 and 4 showing the control procedure of the CPU (20>).

First, in step S1, sensors (A) and (B
), check (C). Whichever sensor (A) or (B) the card is stopped in the card processing device
.

(C) is OFF, and the CPU (20) sets a reject flag in the register R1 in the SO step. S
In step 2, it is determined whether the card reject signal REJ is output from the service machine (23). When the service machine (23) cannot provide a predetermined service to the person who inserted the card even if the card is inserted, the service machine (23) outputs a card reject signal REJ that instructs the card processing device to prohibit acceptance of the card. When the card reject signal REJ is transmitted, the CPU (20) sets a reject flag in the SO step. As a result, even if a card is inserted into the card processing device and the sensor (A) is turned off, the CPU (20) does not drive the motor (12). However, if the sensors (A), (B), and (C) are all ONL, and the card reject signal REJ is not transmitted from the service device (23), the CPU (
20) clears the register R1 in step S3, cancels the reject flag if it has been set, and makes the card processing device ready to accept cards. Then, in step S5, it is determined whether a card has been inserted into the card processing device by checking whether the sensor (A) is OFF. When the insertion of the card is detected, the motor (12) is driven to rotate in the normal direction in step S7. As a result, the inserted card can be transferred into the card processing device. In step S9, it is checked whether the sensor (B) is OFF to determine whether the inserted card has reached the magnetic head (16). In this step, if the sensor (B) does not reach 0FFL within a predetermined time, it is determined that there is an abnormality, and the card processing device stops operating.

When the card reaches the magnetic head (16), the sensor (B
) is 0FFL, the CPU (20) outputs a read start signal R8T to the read circuit (21) in step S11, and starts a read operation. The reading circuit (21) outputs the reading control signal RE to the magnetic head (16), scans the magnetic stripe section ('') of the card through the head (16), reads the completely recorded signal, and reads the signal that has been completely recorded. The signal is converted into a data pulse DP and given to the CPU (20) along with a clock pulse CPr.The CPU (20) sequentially takes in the data pulse DP according to the clock pulse and stores it in the register R2. Proceed to step 813. In step 813, it is determined whether the card has arrived by checking whether the sensor (C) is OFF, and if the sensor (C) is not 0FFL within a predetermined time, it is considered abnormal and the operation of the card processing device is stopped. .

When the card reaches the sensor (C), the rear end of the card is still on the magnetic head (16), so in the next step 315, the card is continued to be transferred after a predetermined delay time. At step S17, the motor (1
2) Stops the drive. At the 8” step, the sensor (B
) to determine whether the rear end of the card has come off the magnetic head (16). When the length of the card is appropriate, the sensor (B) is ONL so that the card separates from the magnetic head (16), but this is 0FFt.
, it is assumed that an invalid card has been inserted and the motor (12) is reversed and returned. However, if the length of the inserted card is normal at this time, the inserted card is stopped in the card processing device with only the leading end of the card resting on the sensor (C). Then, in the next step 821, the authenticity of the card is determined based on the security information recorded in the recording section ("C") among the recorded information of the read card, and if it is a fake card, the motor (12) is reversed. return.

If the card is correct, a write operation will be performed to its magnetic stripe section (''), but first, in step 823, write data is created in register R3.The information to be written is read from this card and stored in register R2. The information is the same as the stored code, but when writing, the value information that was recorded in the recording section ("B) when the card was read is recorded in the recording section ("A). Convert the array and create write data by adding a new hood so that 0 is recorded in the recording section ("B>".
In the 5th step, the motor (12) is driven in reverse, and the next 32
In step 7, it is determined whether the card has reached the magnetic head (16) by checking whether the sensor (B) is OFF. Also in this step, if the sensor (B) is not 0FFL within a predetermined time, it is determined that there is an abnormality, and the operation of the card processing device is stopped. When the sensor (B) turns off when the card reaches the magnetic head (16), the CPU
(20) outputs a write start signal WST to the write circuit (22) in step S29 to initiate a write operation. CPU
(20) sequentially outputs the write data stored in register R3 to the write circuit (22) in synchronization with the encoder pulses from the rotary encoder (14), but this write is performed in the opposite direction to that during reading. In order to accomplish this by transferring the card, the CPU (20) replaces all of the write data from the beginning to the end and outputs it to the write circuit (22). The write circuit (22) takes in the write data pulse WDT from the CPU (20) in synchronization with the encoder pulse CP,
The information represented by the pulse WDT is converted into an analog write signal WT.
is converted into a magnetic head (16) along with a write control signal WR.
) and drives the head (16) to write information on the card. In the next step 831, sensor (B) O
By checking N, it is determined whether the card has finished passing through the magnetic head (16), and the sensor (B
) is not ONu, the operation of the card processing device is stopped. When sensor (B) is turned ON, the card transfer is continued after a predetermined delay time in step 833, and the card is slightly separated from the magnetic head (16), and then the motor (12) is driven in step S35. Stop. By placing a distance between the card and the magnetic head (16) and stopping the motor (12) in this way, the next time the motor (12) is driven to pass the card through the magnetic head (16), Since the card passes through the magnetic head (16) after a period of time has elapsed since the motor (12) started up and the running becomes stable, malfunctions in reading and writing are reduced. Then, in step S37, after ensuring a delay time for motor protection, the motor (12) starts rotating in the normal direction and the card is transferred again in the direction of the sensor (B), and in step S39, the sensor (B) is turned off. is checked to detect the arrival of the card, and if it does not reach 0FFL within a predetermined time, the operation of the card processing device is stopped. In the next 341 steps, the sensor (
B) is checked to determine whether the card has passed,
If it is not turned on within a predetermined time, the operation of the card processing device is stopped. When the card finishes passing through the sensor (B), 8
In step S43, the card transfer is continued after a predetermined delay time, and in step S45, the drive of the motor (12) is stopped to finish accepting the card.Then, the CPU (20)
At step 847, the value information read from the card's recording section ("B>" and stored in register R2) is transmitted to the service machine (23), and then enters a standby state.

In standby mode, only the tip of the card has a sensor (C)
The previous value information is recorded in the recording section ("A), and "O" is recorded as the value information in the recording section ("B). Therefore, even if the card is withdrawn illegally in this state, the card's recording section ("B"
) is written with 0'' as the current value information, so it cannot be used as is.

The service machine (23) performs a predetermined service based on the value information transmitted from the card processing device, and transmits the updated value information after subtracting the consideration for this service to the card processing device. When the CPU (20) inputs this updated value information in 5too steps, the following 8101
In step 5102, the updated value information is set in the part of register R3 that stores "0" to create write data. In step 5102, the motor (12) is driven in reverse and the 810λ In the step, it is determined whether the card has reached the magnetic head (16) by checking whether the sensor (B) is OFF, and if the sensor (B) is not OFF within a predetermined time, the operation of the card processing device is stopped. When sensor (B) turns off,
In step 5105, it is determined whether the card has finished passing through the magnetic head (16) by checking whether the sensor (B) is turned on, and if the sensor (B) is not turned on within a predetermined time, the operation of the card processing device is stopped. do. and the sensor (
When B> is turned on, the card is continued to be transferred after a predetermined delay time in step 5107, and then the drive of the motor (12) is stopped in step 5109. Next 8111
In this step, after securing a slight delay time to protect the motor, the motor (12) is driven to rotate in the normal direction, and the card is transferred toward the magnetic head (16). Then, in step 5113, it is determined whether the card has reached the magnetic head (16) by checking whether the sensor (B) is OFF.
If the sensor (B) does not reach 0FFL within a predetermined time, it is determined that there is an abnormality and the operation of the card processing device is stopped. When the card reaches the magnetic head (16), the sensor (B) turns O.
When the flag is turned FF, the CPU (20) outputs a write start signal WST to the write circuit (22) in step 5115, thereby starting a write operation. That is, the CPU (20) sequentially outputs the write data stored in the register R3 to the write circuit (22) in synchronization with the encoder pulse.
captures the input write data pulse WDT with the encoder pulse and writes it to the magnetic stripe section of the card (16) using the magnetic stripe (16).In the next step 8117, the sensor (B) is turned on. By checking, it is determined whether the card has finished passing through the magnetic head (16), and if the sensor (B) is not turned on within a predetermined time, the operation of the card processing device is stopped.The sensor (B) is turned on. When it is detected, the card is continued to be transferred after a predetermined delay time in 51" steps, and then the motor (1
2) Stops the drive.

In step 5123, after ensuring a delay time for motor protection, the motor (12) starts to reverse rotation to transfer the card toward the magnetic head (16), and in the next step 8125, the sensor (B) is turned off. Check to detect the arrival of the card to the magnetic head (16), and turn it to 0FF within a predetermined time.
If L, the operation of the card processing device is stopped. The card reaches the magnetic head (16) and the sensor (B) turns OFF.
Then, at step 5127, the CPU (20) outputs a read start signal R3T to the reading circuit (21) to initiate a reading operation, and the reading circuit (21) reads the magnetic stripe section ('').
The recorded information is given to the CPU (20), and the CPU (20) stores this data in register R4. next 8128
In this step, it is determined whether the card has finished passing through the magnetic head (16) by checking the ON state of the sensor (B), and if the sensor (B) is not ON within a predetermined time, the operation of the card processing device is stopped. do. Sensor (B) ON
When detected, the card is continued to be transferred after a predetermined delay time in step 8129, and then the drive of the motor (12) is stopped in step 5130. In the next step 8131, the CPU (20) compares the data stored in register R4 with the data stored in register R3 to determine whether proper writing has been performed. If both data match, the next step 8132 secures a delay time to protect the motor and then drives the motor (12) in reverse to transport the card toward the insertion slot (1). . At step 5133, sensor (A) OF
Check F, and sensor (A) turns 0FF within a predetermined time.
If L, the operation of the card processing device is stopped. When the sensor (A) turns OFF due to the arrival of the card, a delay time is allowed in step 5135 to guide the card further to the insertion slot (1), and the card is continued to be transferred.Then, in step 5137, the motor (12) is driven. Stop and finish returning the card.

However, if it is determined in step 5129 that proper writing is not prevented, the process proceeds to step 5139, where a delay time for motor protection is secured, and then the motor (
12) Start the reversal. Then, in the next step 8141, it is determined whether the card has reached the magnetic head (16) by checking whether the sensor (B) is OFF, and if the sensor (B) is 0FFu within a predetermined time, it is determined that there is an abnormality and the card is Stop the operation of the processing device. When the sensor (B) is turned off when the card reaches the magnetic head (16), the CPU (20) executes the write circuit (2) in 5143 steps.
2) Write start signal WST and write data pulse WD
T is output again, and the card processing device writes the card. In the next step 8145, it is determined whether the card has finished passing through the magnetic head (16) by checking the ON state of the sensor (B), and if the sensor (B) is not ON within a predetermined time, the card processing device Stop operation. When the card finishes passing through the magnetic head (16), 5121
