Abstract

PURPOSE:To reduce the consumption quantity of power supply by turning on the power supply of a reader for a recording medium according to the mounting of the card-shaped recording medium and turning off this power supply after the lapse of a fixed time. CONSTITUTION:A switch set part 2 turns on a power supply changeover switch 1 according to the input of a card detection signal and an optical card reader 40 is connected with a power source 39. Then, the optical card reader 40 is operated. On the other hand, a timer 4 starts counting a time according to the input of the card detection signal after a magnetic card or an optical card is mounted. A comparison part 6 compares the count value of the timer 4 with a value set in a time set part 5 beforehand. When the count value of the timer 4 is more than the set value, the power supply changeover switch 1 is turned off since the switch set part 2 is reset. Thus, the useless energy consumption can be reduced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a power supply control system applied to a card check system that checks card-like recording media such as magnetic cards, optical cards, and IC cards used in credit cards. Regarding equipment.

[Prior Art] In recent years, credit cards and the like have been widely used when purchasing products. When a credit card or the like is used, the print seller checks whether there is any problem with the credit card or the like.

In such cases, the checking method used was to turn over a checklist containing data related to the card involved in the accident, or to make an inquiry to the host computer at the center based on the In No of the credit card.

However, all of the above-mentioned checking methods have a problem in that they are time-consuming and cannot be checked quickly. Furthermore, the method of flipping over the checklist has the disadvantage that the checklist must be rewritten every time an accident card is notified. For this reason, a card check system has been proposed in which check data is recorded in a large-capacity storage unit, such as an optical recording medium, and the card-shaped recording medium is checked.

[Problems to be Solved by the Invention] However, the reading device for optical recording media, etc. as described above consumes a large amount of power because it has a mechanical part that drives the optical recording medium, etc., and is constantly in operation while the card check system is operating. There was a problem that the amount of power consumed was high when the power was turned on.

[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, the present invention provides a means for solving the above-mentioned card-like recording medium by comparing read data of the card-like recording medium with check data recorded on a predetermined recording medium. In the card check system that performs the check, there is a power switch that turns on and off the power of the reading device that reads the recording medium of the check data, and the power switch is turned on when the card-shaped recording medium to be checked is installed. a timer that counts the time after the card-shaped recording medium is attached; a time setting section that sets a certain time in advance; and a timer that compares the values of the timer and the time setting section to The present invention is characterized in that it includes a comparison section for controlling.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a block diagram of a card check system to which the power supply control device of the present invention is applied. First, an overview of this card check system will be described.

In the figure, the card check system includes a magnetic card reader 31 and an optical card reader 32 that read predetermined data recorded on a magnetic card and an optical card, which are card-like recording media used in credit cards, as a card reading unit, and an optical card reader 32 for checking. An optical card reader 40, EEPROM 41 and ROM 42 as a data recording section, a microcomputer (CPU) 50 as a judgment section, an LCD (liquid crystal display) 60 and a printer 61 as an output section,
It is configured to include a ten-key keyboard 70 and a communication device 80 as an input section.

Figure 4 shows an optical card reader 40EEPROM installed in the main body 33.

This is an example in which a D60 and a ten-key keyboard 70 are accommodated, and a magnetic card reader 31, an optical card reader 32, a printer 61, and a communication device 80 are connected externally to the main body 33.

Alternatively, all the component devices may be integrally housed in a single housing.

The optical card reader 40 is a magnetic card, an optical card reader, and an optical card reader.
A magnetic card reader 31 is connected to an optical card 35 in which card information including the D No. and details of the accident on the card are written.
．． Card information corresponding to the magnetic card or optical card read by the optical card reader 32 is read. EEFROM41 above
is for writing data from a key or optical card when there is an emergency notification etc. related to a credit card. The ROM 42 stores programs for judgment and control by the microcomputer 50.

The microcomputer 50 has a magnetic card reader 3.
1 or the optical card reader 32 or searches the credit card check data from the optical card 35 to judge whether the credit card is good or bad, and also controls the magnetic card reader 31, the optical card league 40, etc.

Here, the check data stored in the optical card 35 read by the optical card reader 40 is as follows.

As shown in FIG. 5, it is composed of a directory 36 and a block 37.

In the directory 36, there is I[lNO] at the beginning of each block 37 of the credit card accident card list.

and block number are stored. Also, block 37
A plurality of blocks are sequentially provided corresponding to the block numbers of the directory 36, and each block 37 sequentially stores the In No. of each accident card and the contents of each accident.

Next, the operation of card checking by the above-mentioned card checking system will be explained based on the flowchart of FIG.

In this embodiment, the optical card 35 read by the optical card reader 40 has 10 NOs of the credit card in which the accident occurred and details of the accident written in the directory structure shown in FIG. 5 as check data. ing.

First, the check data stored in the prepared optical card 35 is read by the optical card reader 40 (step S
1) This check data is stored in the microcomputer 50.
The data is stored in the memory unit (RAM) of.

After the reading is completed, the microcomputer 50 inserts the credit card into the magnetic card reader 31 if it is a magnetic card or into the optical card reader 32 if it is an optical card and reads its III No. (step S2). The read In No. is compared with the check data directory 36 to search for the corresponding check data (step S3). If there is no corresponding check data, 10 NO and OK are displayed on the LCD 60 and the corresponding check data is searched. It is notified that there is no problem with the credit card (step S5), and then the printer 61 prints the 1080. and a deadline, name, etc. (step S7).

If there is corresponding check data, the microcomputer 50 checks the corresponding block 37 along with its In No.
The details of the accident written in are displayed on the LCD 60 (step S6).

With the above steps, the credit card check is completed. Incidentally, in the case of an accident card, it may be printed in step S7, or the printer 61 may be used instead of an imprinter to print on the sales slip.

When emergency notification of check data is performed using a ROM card or optical card, read the list of accident cards stored in the sent ROM card or optical card and EEF.
When writing into the ROM 41 and therefore checking, the microcomputer 50 also accesses the EEPROM 41.

When an emergency notification is sent by postcard, etc., the operator looks at the postcard and directly enters the EEP using the numeric keypad 70.
Write to ROM41.

When making an emergency notification by communication, the data sent from the center is received by the communication device i80 and stored in the EEFROM.
Write to 41.

Although the above explanation has been about checking credit cards, it goes without saying that the application can be applied to other cards, and the card-like recording medium is not limited to magnetic or optical cards, but may also be IC cards, etc. Although the optical card reader 40 is used as a part, a CD-ROM, a DAT league, a floppy disk, etc. may also be used.

Here, a power supply control device applied to the above-described card check system will be explained.

FIG. 1 is a block diagram showing a power supply control device according to an embodiment of the present invention.

The power supply control device of this embodiment is for on/off control of a power supply 39 for operating an optical card reader 40 of an optical card, which is a medium for recording check data.
A timer 4 that counts time is equipped with a power selector switch 1 that turns on and off the power switch 1, and a switch setting section 2 that sets the power switch 1 to turn on and off.
, a time setting section 5 that sets a constant time, and a comparison section 6 that compares the count value of the timer 4 and the setting value of the time setting section 5. Further, the switch setting section 2 is constituted by a flip-flop.

In this embodiment, the power supply 39 is turned off and the optical card reader 40 does not operate even if the card check system is started.

When a magnetic card is inserted into the magnetic card reader 31 or an optical card is inserted into the optical card reader 32, the magnetic card reader 31 or the optical card reader 32 detects the insertion of the card and outputs a card detection signal.

The switch setting section 2 is set by the input of the card detection signal, and turns on the power switch l. As a result, the optical card reader 40 and the power supply 39 are connected, and the optical card reader 40 is operated.

On the other hand, the timer 4 starts counting the time after the magnetic card or optical card is inserted by inputting the card detection signal.

The comparison unit 6 compares the count value of the timer 4 and a value preset in the time setting unit 5 (for example, the end of work time). Then, when the count value of the timer 4 exceeds the set value, the switch setting section 2 is reset. This turns off the power selector switch l. Also, reset the timer.

Corresponds to the following actions: By performing such an operation, wasteful power consumption can be minimized.

In addition to using the mechanical switch shown in FIG. 1 as the power switch 1, an electrical switch such as a transistor may also be used.

[Effects of the Invention] As explained above, the present invention turns on the power of the recording medium reading device by attaching a card-shaped recording medium such as a credit card, and turns off the 'Itt source after a certain period of time has elapsed. Since the recording medium reading device does not operate except when reading the card-shaped recording medium, power consumption can be reduced.
