Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a card-type service device that provides various services in accordance with monetary data recorded on a card such as a magnetic card.

[Conventional technology]

Recently, devices have been proposed that sell tickets by inserting a card with amount data recorded on it.This type of device reads the amount data recorded on the card and issues tickets according to this data. In addition to allowing services such as the following, the card will be returned after recording the amount of money reduced according to the service.

[Problem that the invention attempts to solve]

However, in this type of card-type service device, the recording function can be used by disassembling the related parts, removing the base that is detachably attached to the main body, and making some modifications to the control section. Moreover, it is possible to re-record the amount data on a used card whose amount data has become zero, and there is a risk that the card may be counterfeited.

[Means for Solving the Problems] The present invention has been made in view of the above problems. This volatile memory is stored in the main body, and this volatile memory is mounted on a base that is detachable from the main body, and when the base is attached to the main body, power is supplied to the volatile memory through the connection terminal with the main body. In addition to connecting a backup power supply to the volatile memory, the power supply path between the volatile memory and the backup power supply on the base is equipped with a power supply circuit for fraudulent purposes such as card forgery. The manual switch can be inserted without a third party being able to easily know its existence or operating conditions.

[Effect]

Therefore, according to this invention, if the manual switch is not switched from the open state to the closed state when the base is removed from the main body, the manual switch is closed in advance and the backup power source is switched to the volatile memory. If the base is not removed after the base is removed, the power supply to the volatile memory is cut off when the base is removed, and the programs and programs that control read and write operations for the cards stored in the volatile memory are At least part of the fixed data is destroyed. [Example] Hereinafter, details of the present invention will be explained with reference to figures showing examples.

Figure 1 is a block diagram showing the entire configuration of a card-type automatic ticket issuing machine.
A CNU and a card unit CDU are provided, and a control unit CTU and a memory unit MMU are provided for the purpose of controlling these and controlling the ticket issuing unit FTU based on data from these.

The control unit CTU includes a control circuit CNT consisting of a processor such as a microprocessor, a memory, etc.
It is equipped with a display section DP that displays the input amount, magnetic card amount data, etc. according to the output of this, and the variable memory RAM _p using volatile memory of the memory unit MMU has read and write operations for the magnetic card. Control programs and fixed data are stored, and the contents of this are transferred to the control circuit CNT.
The processor is executed and controls the card unit CDU via the circuit unit CCU, and also processes the data to be received.

In addition, the card reading circuit of the circuit unit CCU
CRC, card writing circuit CWC, card drive mechanism CDR of card unit CDU, punch mechanism
There is a circuit unit between PNT and control circuit CNT.
The CCU is connected via the connection circuit CNC, and signals are exchanged through this. If the circuit unit CCU is carelessly removed from the main body, the connection by the connection circuit CNC will be lost as described later. The condition becomes unrecoverable and the card unit CDU
The operation is no longer performed normally.

Note that this also applies to the memory unit MMU, and if it is carelessly removed from the main body, the variable memory
The contents of RAM _p will be completely destroyed as described below, making it completely impossible to record on the magnetic card.

Here, when a magnetic card is inserted from the card insertion slot ENT _c of the card unit CDU, the card drive mechanism CDR is activated under the control of the control circuit CNT, and the magnetic card is transferred while facing the reading head RH. The output of the head RH is given to the card reading circuit CRC, from which a signal indicating the amount data is sent to the control circuit CNT.

Then, the control circuit CNT judges the amount data and
If the value is such that the service is acceptable, the ticketing unit
It controls the FTU to issue tickets, calculates the amount data by subtracting the issued ticket amount, and controls the card drive mechanism CDR to write the magnetic card into the write head.
The deducted amount data is updated and recorded on the magnetic card since it runs opposite to the WH and provides the amount data to the card writing circuit CWC.

Next, the magnetic card is transferred to the card punch mechanism PNT in response to the operation of the card drive mechanism CDR under the control of the control circuit CNT, and the magnetic card is transferred to the card punch mechanism PNT under the control of the control circuit CNT.
After receiving a punch indicating the remaining amount according to the control of
It is returned to RET _c , and if the amount data becomes zero, it is stored in the zero guard storage box TKB.

Note that the ticket issuing unit ETU is controlled by the control circuit.
This is carried out by a program stored in the memory within the CNT, and the coin storage operation by the coin unit CNU is also carried out in the same way.

In other words, in the coin unit CNU, a coin inserted through the slot ENT _T undergoes mechanical outer diameter discrimination and electrical material discrimination by the material discrimination circuit MJC, and a control circuit responds to the discrimination output of the circuit MJC. Under the control of the CNT, the coins are sorted in the sorting unit SEL, and only genuine coins are stored in the storage unit ACC, while irregular coins are returned to the return slot RET _T.

The storage unit ACC is equipped with a photoelectric or mechanical accumulated coin detector, and according to the detection output of this, the control circuit CNT determines whether ticket issuing should be permitted or not. Storage/return department CRT
controls and stores the coins in the safe CBX,
Storage is confirmed by the detection output of a photoelectric or mechanical detector, and the ticket issuing unit FTU is controlled to issue tickets.

If you have any surplus coins, please contact the storage/return department.
Controls the CRT and returns it to return port RET _T.

While data is accessed through data terminals P _d1 to _{P do} , both poles of switch S ₁ are connected to _power control terminals P p1 and P _p2 , and correspondingly,
Jacks J _p1 and J _p2 are short-circuited by a short-circuit wire SL.

For this purpose, switch S ₁ is turned on, a program and fixed data for controlling read and write operations are applied from data terminals P _d1 to P _do , and after these are stored in variable memory RAM _P , each terminal P _d1 ~
If P _do , P _p1 , P _p2 are inserted into the jacks J _d1 ~ J _do , J _p1 , J _p2 and the base is attached to the control unit CTU, a short-circuit wire SL is connected between the power supply control terminals P _p1 and P _p2 . shorted,

If you turn on the switch S ₁ in advance and set the battery B ₁ to a backup state, then remove it.
The power supply state to the variable memory RAM _p is maintained, and the contents of the variable memory RAM _p are maintained as they are.

On the other hand, if a third party carelessly removes the switch _S1 without turning it on without knowing the existence or operating conditions of the switch _S1 , the power supply to the variable memory RAM _p will be cut off and the contents will be lost. Because it evaporates immediately,
After that, reading and recording operations are no longer possible.
Counterfeiting of magnetic cards is prevented.

Note that the contents stored in the variable memory RAM _p may be part of the program and fixed data that control the reading and recording operations, and since the reading and recording operations are performed as a series, if any one of these routines It is only necessary to store the parts and assume that any part will be lost due to careless removal.

_The battery B ₂ used as a backup power source is connected to the power _terminal of this, and the It was inserted in such a way that the person could not easily know its existence or operating conditions. In addition to mounting switches S ₂ and the like, the base also includes a jack J _s1 that accommodates wiring S ₁ to _{S 6} from the control unit CTU.
~J _s6 and card unit CDU jack
Each terminal P _s1 to P _s5 inserted into J _e1 to J _e5 , J _p3 , J _p4 ,
P _s3 , P _s4 , and terminals t ₁ to _{t o} used when storing data in the variable memory RAM _c are provided, and both poles of the switch S ₂ are connected to power control terminals P _p3 , P _p4
The corresponding jacks J _p3 and J _p4 are short-circuited by a short-circuit line SL.

Therefore, by inserting the terminals P _s1 to P _s5 , P _p3 , and P _p4 into the jacks J _c1 to J _c5 , J _p3 , and J _p4 and attaching the base to the card unit CDU, the switch S ₂ can be turned off. The variable memory RAM _c is also in the power supply state, and by giving a write command signal from the jack J _s6 and giving data d ₁ to d _o specifying the connection status to the connection circuit CNC, these are changed to the variable memory RAM _c. is stored in

In addition, the connection circuit CNC is composed of multiple analog switches, selectors, etc.
By operating the terminals d ₁ to d _o in a predetermined state, the connections between the jacks J _s1 to J _s3 and the terminals P _s1 to P _s3 and between the jacks J _s4 and J _s5 and the card reading circuit CRC and card writing circuit CWC are established. It is designed to be connected to each individual.

Therefore, after inserting the terminals P _s1 to P _s5 , P _p3 , and P _p4 into the jacks J _c1 to J _c5 , J _p3 , and J _p4 , the circuit unit is assembled.
After attaching the CCU base to the card key unit CDU, variable memory can be used even if switch _S2 is turned off.
The power supply state to RAM _c is maintained, and the wiring S ₁ to S ₆ is connected to the jacks J _s1 to J _s6 .
When a read command signal is given from the control unit CTU through wiring _S6 , data _d1 to _d0 of the variable memory RAM _c is sent to the connection circuit CNC, and the connection circuit responds accordingly.
The CNC becomes in a predetermined connection state, and the card unit CDU performs normal operations under the control of the control unit CTU.

When removing the circuit unit CCU for maintenance or inspection, turn on switch _S2 before removing it. This will maintain the power supply status to the variable memory RAM _c , so the contents of the variable memory RAM _c will be is retained as is.

On the other hand, if a third party does not know about the existence or operating conditions of switch S ₂ and carelessly removes it without turning on switch S ₂ , the power supply to variable memory RAM _c will be cut off and the contents will be immediately lost. Since it volatilizes, it becomes impossible to bring the connection circuit CNC into a predetermined connection state even if a read command signal is given, and the card unit CDU will not operate normally.

Therefore, if the content structure and data d ₁ to d _o of the connection circuit CNC are kept secret, counterfeiting of the magnetic card can be prevented.

However, the installation part of each unit MMU and CCU can be selected arbitrarily as long as it is a part that will be disassembled during modification for the purpose of counterfeiting.Batteries B ₁ and B ₂ are not mounted on the base and the lead wires are The same effect can be obtained by connecting the batteries B 1 and B 2 by connecting the batteries B ₁ and B ₂ with the power supply control terminals P _p1 and P _p4 , respectively.

In addition to magnetic cards, any card that has recording and playback functions can be used, and can be used not only in automatic ticket machines but also in various vending machines, charge-type public telephones, etc. Applicable.

The switches S ₁ and S ₂ should be small enough to be difficult to detect, should be installed in locations that are difficult to find, and should not have any special display, but key switches operated by keys may also be used. Alternatively, various modifications are possible, such as using a switch circuit, a decoder, etc. as the switches S ₁ and S ₂ and turning them on by inputting a specific code.
