Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to the Chiyashi register or P
At OEJ terminal, credit card or V'i
The present invention relates to a card reader that can read bank card information and input a password.

(Prior art) Canon Eregister or POS terminals are equipped with a card reader and keyboard built-in or connected by wire so that payments can be processed using credit cards or bank cards.Such technology As shown in [OMRON News No. 465J (published September 24, 1985).

[Problem that the invention seeks to solve]

In the above-mentioned conventional example, when a purchaser makes a payment using a card, he or she first cleans the card reading section of the card and collects the card information, and then has the purchaser input his/her personal identification number on the keyboard section. Since the gearboard part is built into the register or connected by wire, the purchaser needs to place it near the register. Furthermore, when entering the PIN number, there was a risk that the store clerk who operated the register would know the ILF ID number, making it impossible to maintain confidentiality.

In order to solve this problem, it is necessary to physically separate only the card reading section and the keyboard section where the PIN can be entered from the register and make it a portable card reader that can be handed to the purchaser. The power supply to the reader must be connected to a built-in battery. However, if it is to be portable, it needs to be small and the battery has to be small, resulting in a small capacity and the number of card readings per unit of storage is reduced.The primary battery is replaced more frequently, and the secondary battery is recharged. it
There are serious problems 0 1 This invention has 1! The purpose is to reduce power consumption per i crop and increase the number of times of use per unit crop.

[Means for solving the problem J After the card reading section of the card reader completes the reading operation,
The above object can be achieved by providing a power supply circuit that stops power supply to the card reading section at least while the password is being input using the keyboard.

[Operation] After the reading operation of the card reading section is completed, the power supply to the card reading section is stopped, so that battery consumption can be suppressed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a card reader 100 according to the present invention. The card reader 100 has a groove 110 through which the magnetic card 300 is passed in the A direction in order to read the magnetic stripe 301 of the magnetic card 600, and a keyboard 130 for inputting a password. The display section 4 of the card reader 100 performs display according to the operating state of the card reader. The display is performed by causing the light-emitting element to the left of the characters printed on the card reader 100 to emit light. The dP200 is a stand on which the card reader 100 is mounted. When the card reader 100 is installed, it has an interface section 210 for receiving and receiving information read from the card held in the card reader 100 and input/reports from the board. The interface section 210 communicates with the card reader 100. In order to establish a wireless connection between the card reader 200 and the card reader 200, information is transmitted to the card reader 200%'s interface section 12 (1) using light.

Information received by bookie 200 is received via connector 220 to PO8 terminal (not shown).

FIG. 2 is a block diagram of the circuit inside the card reader 100.

In FIG. 2, power is supplied from the battery 7 to the control unit 1 as indicated by solid lines P1 to PS. The storage section 51 is connected to the first section 4 - 1 of the display section 4 and the power supply cutoff circuit 8 . Another part 4-2 of the display section 4. Card reading section 2. Power is supplied to the personal identification number input section 3 via a power supply cutoff circuit 8 through a path shown by solid lines P4 to P6. Power supply and disconnection control of the power supply cutoff circuit 8 is performed by determining the operating state of the card reader 100 by the operating state monitoring circuit 9 in the control circuit 1.

The card reading section 2 is provided in the groove section 110 (FIG. 1),
The magnetic stripe 301 of the card 500 is read. The password input section 3 encodes the password entered through the keyboard 130 (FIG. 1). Also, part 4 of the display section 4
-1 corresponds to, for example, a light-emitting element that displays the operating status of the card reader, such as "card reading", "PIN input", "input complete", and "idle state";
The section 4-2 corresponds to, for example, a light emitting element that displays "t# on".

Next, the operation flow and power supply state of the card reader 100 will be explained using FIG. 5.

When this card reader executes mode block 1 o te tf "source on", mode block 12 "read card"
Enter the mode. At this time, '1' appears on the card reading section 2! supply the source. When the card reading section 2 executes card reading and the card information is successfully retrieved, the control section 1 causes the card reading information to be temporarily stored in the storage section 5, and the mode block 13
The mode will be changed to "Password input" mode. When the operating state monitoring circuit 9 learns that the card reading information has been stored in the storage section 5, it controls the power supply cutoff circuit 8 to cut off the power supply to the card reading section 2, and also disconnects the password input section 3. Start supplying power to. When the purchaser finishes inputting the password, the control section 1 temporarily stores the password in the storage section 5 and shifts to the "transmission" mode of the mode block 14. When the operating state monitoring circuit 9 learns that the password has been stored in the storage section 5, it controls the power supply cutoff circuit 8 to cut off the power supply to the password input section 5. This card reader is Detsu-P2
oo (FIG. 1), the transmitting/receiving section 6 (interface sections 120, 210 (FIG. 1)) is connected to the bouquet 200.
(equivalent to), the information in the storage unit 5 is sent out. After the information in the storage section 5 is sent to the deck 200 in the "transmission" mode, the control section 1 automatically erases the information in the storage section 5 and shifts to the "idle" mode of the mode block 15. In this case, the circuit configuration may be changed so that the power supply cutoff circuit 9 is controlled by the B.1 operation status monitoring circuit 9 to stop the power supply to the storage section 5.

In the "idle" mode, the LSI of the control unit 1 is set to a power save mode to reduce power consumption in preparation for the next card operation mode block 11.

The transition from the "1 idle" mode to the "card reading" mode may be performed using one input-enabled board that is always powered. This corresponds to the key 140 in FIG. 1 (not shown in FIG. 2).

As explained above, a series of card operations can be executed any number of times while the power is on. If the card will not be operated for a long time, one person manually operates the switch 150 (FIG. 1) to turn off the power in the mode block 16.

Note that power supply to and disconnection from the display unit 4 may be performed by supplying power to and disconnecting from a portion of the display unit required in the valley operation mode depending on the operating state.

In this embodiment, the card reading section 2 is shown as one that reads magnetic cards, but it may also be one that reads industrial C cards. Furthermore, even if the configuration unit is slightly different from the above-described embodiment, as long as the power supply and disconnection are controlled according to the operating state,
It is within the scope of the present invention.

It goes without saying that in the above embodiments, the battery 7 may be either a secondary battery or a secondary battery.

〔Effect of the invention〕

According to the present invention, power is supplied only to necessary constituent units according to the operating state, so the power consumption per card operation can be reduced, so the number of card operations per unit battery can be increased. be able to.

Therefore, the capacity of the battery can be reduced, the device can be made smaller, the frequency of battery replacement and light range can be reduced, and an inexpensive and easy-to-operate card reader can be provided.
