DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Application Field) The present invention relates to a portable medium processing device that processes portable media such as magnetic cards and IC cards.

(Prior Art) A portable medium processing device, for example, a reading/writing device, is a terminal device such as a keyboard dispenser used in a bank, etc., and a host device that controls this terminal device. has. The host device performs a predetermined operation after confirming the insertion of a portable medium (hereinafter simply referred to as a "card") such as a magnetic card or IC card into the terminal device and the presence or absence of the required manual key operation. In this case, the host device will especially check the presence or absence of key manual operation.
A command message "key manual operation" is sent to the terminal device. When the terminal device receives this command message, it checks whether the required key has been manually operated and sends the result back to the host device. If the terminal device returns information that the required manual key operation has been performed to the host device, the host device can perform the specified operation in response to the manual key operation, but the command message for confirming the manual key operation is If the key has not been manually operated even after transmitting the key, the host device needs to wait for a predetermined period of time until the key is manually operated.

In this manner, it is necessary for the host device to monitor for a predetermined period of time whether or not the required key manual operations have been performed. That is, the host device performs the conventionally required waiting time setting and monitoring operations for manual key operations.

Incidentally, the host device performs these processing operations by program processing, but the memory footprint of the program required for these processing operations is relatively large.
In the case of a host device with a small total memory capacity, a considerable portion of the memory is occupied by the program memory for this processing operation.

(Problem to be Solved by the Invention) Since the host device performs the necessary waiting time setting and monitoring operations for key manual operations, the relatively large program required for these processing operations in the host device There is a problem in that the memory capacity and processing time are occupied and the memory capacity and processing time are insufficient for other processes.

The present invention has been made in view of the above, and its purpose is to improve the processing time of the host device by monitoring the information saw operation during the waiting time for inputting the required information in the terminal device. An object of the present invention is to provide a portable media processing device that reduces the amount of damage.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, a terminal device 21 including an information input device 20 and into which a portable medium is inserted, and a terminal device 21 connected to the terminal device 21, A command message to confirm the presence or absence of information input via this information input device 20 is sent to the terminal device 2.
As shown in FIG. A time setting means 1 sets wait time information for information input in the command message to be sent, and a terminal device 21 that receives the command message having the wait time information for information input set by the time setting means 1 converts it into the command message. The gist of the present invention is to include a monitoring means 3 for monitoring information input for a set waiting time for information input.

(Operation) In the portable media processing device of the present invention, the terminal device itself inputs information via the information input means based on the waiting time for information input in the command message sent from the host device to the terminal device. It is supposed to be monitored.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 is a block diagram of an embodiment in which the present invention is applied to a card reading/writing device. The card reading and passing device shown in the figure is composed of a terminal device 21 into which a card such as a magnetic card or an IC card is inserted, and a host device 23 that is connected to the terminal device 21 and controls the terminal device 21. The terminal device 21 includes a keyboard 24 and a display 2 for the user to input various information.
It has an information input device 20 consisting of 6.

The host device 23 needs to check whether required information has been input via the information input device 20 when performing predetermined processing. More specifically, if the present card reading/writing device constitutes a cash dispenser installed in a bank or the like, the user may press, for example, one of the multiple buttons on the keyboard of the cash dispenser. When the user presses the payment request button and inserts the card, the host device 23 responds by instructing the user to enter the PIN number, and the PIN number is entered via the keyboard 24. The system then confirms that the PIN number has been entered and confirms that it matches the PIN number stored on the card before processing the payment.

In this case, in order to confirm that the PIN number has been input, the host device 23 sends the terminal device 21 to the terminal device 21 as shown in FIG.
Send the information input command message 25 in the format shown in a). This information input command message 25 includes key manual input instruction information 25a, key manual digit number information 25b, and key manual waiting time information 25c. When the terminal device 21 receives this information input command message 25, it monitors the insertion of the password specified by the key manual instruction information 25a during the waiting time specified by the key manual waiting time information 25c. It has become. Then, the response message 27 in the format shown in FIG. 3(b) shows the result of monitoring the input of this clear identification number, that is, the monitoring result that the PIN was entered or the PIN was not entered within the waiting time for the key. The host device 23 is notified by sending it back to the host device 23. Note that the time set in the key human power waiting time information 25c is appropriately varied by the host device 23 in consideration of the type of information input to be waited for, the purpose of use of the terminal 21, and the like.

Note that here, the key input to be monitored will be explained as inputting a password, for example.

When the user presses the payment request button on the information input device 20 and inserts the card into the terminal device 21 in order to withdraw a deposit using the cash dispenser, the terminal device 21 outputs this to the host device 23. (Step 100). As a result, the host device 23 outputs an information input command message 25 to the terminal device 21 to prompt the user to input the password.

Once these pieces of information are set, the terminal device 21 checks whether a password has been input via the information input device 20 (step 150). This check is performed when the number of digits of the information input by operating the keyboard 24 matches the number of digits shown in the key manual digit number information 25b.

As a result of this check, if it is determined that the PIN number has been entered, the terminal device 21 will return a response message 27 indicating that the PIN number has been entered to the host device 23, and subsequent payment processing will be performed. (Step 160).

On the other hand, entering the PIN is the key to manual waiting time information 25C (
If there is no samurai within the indicated time, terminal device 2
1 returns an error response message to the effect that the PIN has not been entered to the host device 23, and receives instructions from the host device 23 (steps 170 and 180).
.

In addition, in this embodiment, the key input to be monitored has been explained as inputting a password, but it is not limited to this.
Of course, it can be applied to any other key personnel.

The terminal device 21 is. When the information input command message 25 transmitted from the host device 23 is received, the key manual instruction information 25a, the key manual digit number information 25b, and the key manual waiting time information 25c set in the information input command message 25 are read out. information is set in a register or the like (steps 110 to 140).
