Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention has a portable medium such as a magnetic card or an IC card inserted therein, and can read and carry information from the portable medium. The present invention relates to a portable medium reading / writing device that writes information on a medium.

(Prior Art) A portable medium reading / writing device has a terminal device such as a cash dispenser used in a bank or the like and a host device for controlling the terminal device. The host device performs a predetermined operation after confirming whether or not a portable medium such as a magnetic card or an IC card (hereinafter simply referred to as “card”) inserted in the terminal device is inserted. In this case, the host device is a card. A command message "insert card" is transmitted to the terminal device in order to confirm the presence or absence of insertion. Upon receiving this command message, the terminal device checks whether or not a card is inserted, and returns the result to the host device.
When the information indicating that a card is inserted is returned from the terminal device to the host device, the host device can perform the specified operation for the inserted card, but sends a command message for card insertion confirmation. However, if the card is not inserted yet, the host device needs to wait for a predetermined time until the card is inserted into the terminal device.

Thus, the host device needs to monitor whether or not the card is inserted in the terminal device for a predetermined time. That is, the upper-level device conventionally performs the card insertion waiting time setting and monitoring operation.

By the way, the higher-level device performs these processing operations by program processing, but the memory capacity of the program required for these processing operations is relatively large.
In the case of a host device having a small total memory capacity, a large part is occupied by the program memory for this processing operation.

(Problems to be Solved by the Invention) Since the host device sets and monitors the card insertion waiting time, the memory capacity and the process are controlled by a relatively large program required for these processing operations in the host device. There is a problem that time is occupied and the memory capacity and processing time for other processing become insufficient.

The present invention has been made in view of the above, and an object of the present invention is to monitor the insertion amount of a portable medium during the insertion waiting time of the portable medium in a terminal device, thereby executing the program amount and processing of a host device. (EN) Provided is a read / write device for a portable medium which saves time.

[Structure of the Invention] (Means for Solving Problems) In order to solve the above problems, a terminal device into which a portable medium is inserted and a presence / absence of insertion of a portable medium into the terminal device connected to the terminal device are confirmed. In a device having a host device for controlling the terminal device to perform the reading and writing operation of the portable medium inserted in the terminal device after transmitting the command message of ??? Time setting means for setting the insertion waiting time information of the portable medium in the command message transmitted from the device to the terminal device,
And a monitoring unit for monitoring the insertion of the portable medium during the time set in the command message in the terminal device that received the command message having the insertion waiting time information of the portable medium set by the time setting unit. Is the gist.

(Operation) In the portable medium reading / writing device of the present invention, the terminal device itself inserts the portable medium based on the insertion waiting time of the portable medium in the command message transmitted from the host device to the terminal device. It is supposed to monitor.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment in which the present invention is applied to a card reading / writing device. The card reading / writing device shown in the figure comprises a terminal device 21 into which a card such as a magnetic card or an IC card is inserted, and a host device 23 connected to the terminal device 21 and controlling the terminal device 21.

The upper device 23 needs to check whether or not a card has been inserted into the terminal device 21 before performing a predetermined process.
More specifically, when the card reading / writing device constitutes a cash dispenser installed in, for example, a bank, the user selects, for example, a payment request button from among a plurality of buttons of the cash dispenser. When pressed, the host device 23 gives an instruction to the user to insert the card in response to this request, and monitors the insertion of the card. Then, after confirming that the card has been inserted, the information stored in the card is read and the contents are confirmed, and then the payment processing and the like are performed.

In this case, in order to confirm that the card has been inserted into the terminal device 21, the host device 23 instructs the terminal device 21 to insert the card insertion command message 2 in the format shown in FIG.
Send 5. In this card insertion command message 25, card insertion waiting time information 25a is set. Terminal device 21
When the card insertion command message 25 is received, the device monitors the insertion of the card during the waiting time indicated by the card insertion waiting time information 25a. And
This card insertion monitoring result, that is, the information of the monitoring result that the card has been inserted or the card has not been inserted within the card insertion waiting time, returns the response message 27 in the format shown in FIG. Notify by doing.

FIG. 4 is a flow chart showing the card insertion monitoring operation in the terminal device 21, and the operation will be described below according to this flow.

When the terminal device 21 receives the card insertion command message 25 transmitted from the host device 23, this card insertion command message 25
The card insertion waiting time information 25a set to 25 is read and this card insertion waiting time information is set in a register or the like (steps 110 and 120).

When the card insertion waiting time is set, the card sensor provided in the card slot of the terminal device 21 is checked to see if a card has been inserted into the terminal device 21 (step 130). This check is performed because when the card is inserted, the light to the sensor is blocked by the card so that it becomes dark, and when the card is not inserted, the light to the sensor is not blocked by the card and is bright.

As a result of this check, when the light to the sensor becomes dark and it is identified that the card is inserted, the card is detected by the terminal device 21.
While being taken in, the response message 27 is returned from the terminal device 21 to the higher-level device 23 and normal processing is performed (step 140).

When the light to the sensor remains bright and the card is not inserted, the 1 second counter is decremented and the card insertion waiting time is subtracted every 1 second until the card insertion waiting time becomes "0". It is checked whether a card has been inserted (steps 130, 150 to 180).

Even if the set card insertion waiting time becomes “0”, if the card is not inserted, the terminal device 21
In response, an error response message indicating that the card is not inserted within the waiting time is returned to wait for an instruction from the host device 23 (step 190).

[Effects of the Invention] As described above, according to the present invention, the terminal device itself inserts the portable medium based on the insertion waiting time of the portable medium in the command message transmitted from the host device to the terminal device. Since monitoring is performed, the amount of programs in the host device can be reduced, processing time can be spared, and economic efficiency and reliability can be improved.
