Abstract

PURPOSE:To attain the effective use of the data read out of a magnetic card put into a card reader by using a detection means which detects both insertion and extraction of the card and holding the data stored in a buffer memory during insertion of the card and then clearing the data when the card is extracted. CONSTITUTION:When an inserted card 10 reahes a card insertion detector 12, the position of the card is informed to a CPU1 by a card. Thus a read instruction is delivered to a buffer memory 13. However both the CPU1 and the memory 13 are not reset at a time. In other words, the CPU1 refers to the contents of the memory 13 and can confirm an operator in case plural jobs are designated. Thus the operator can perform continuously plural jobs just by putting an ID card into a card reader. Furthermore the contents of the memory 13 set within the card reader are erased with extraction of the card. This prevents perfectly the misuse of the card reader to an outsider.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a magnetic card reading device, and relates to a magnetic card reading method that enables more effective use of data read into a backup memory. .

(2) Prior art and problems Conventionally, in a data processing device such as a transaction device, when a specified operator is registered, the operator is identified by a magnetic card reading device (card reader) attached to the device. It is configured to insert a magnetic card (ID card). Then, check the data on the card and the registration code.
If it is K, a predetermined job is started. In this type of card reader, in order to maintain the confidentiality of the ID code, the ID card is read, temporarily held in a buffer memory, and sent to a verification section, and the contents of the buffer memory are reset and erased.

FIG. 1 is a schematic diagram of the device, and FIG. 2 shows a control circuit of a conventional card reader. In FIG. 1, under the control of a data processing device 1, commands and data are stored in and read from a memory 2, necessary manual input is performed on a keyboard 3, predetermined processing is executed, and the result is is displayed on ORT 4. If this process is limited to a specific operator, the user can insert the ID card into the card reader 5.
If OK, startup is performed.

FIG. 2 is an explanatory diagram of a conventional card reader.

In the figure, when a card 10 is inserted into an insertion slot of a card reader 5, a feeder 2 (not shown) operates, and a magnetic head 11 reads data on the magnetic stripe on the card. The read data is temporarily held in the backup memory 13. This backup memory 15 is provided in the bus interface section of the card reader 5. When the card 10 reaches the card insertion detector 12, the detection signal turns on and a notification that the card data exists is sent to the CPU 1.
sent to. Then, the OPU 1 issues a read command to the Shibara fabric memory 13, and the read data is sent to the OPU 1 via the memory 2. At the same time, a reset is applied and the contents of the buffer memory 15 are erased.

In this case, depending on the type of device, the operator may want to perform multiple jobs in succession, but with the above method, an ID card must be inserted for each job.

The extraction must be repeated. Therefore, the operation of registering the operator is troublesome. Therefore, it is desirable to be able to read the buffer memory 13 for each job at any time while the ID card is being inserted.

(3) Purpose of the Invention The purpose of the present invention is to provide a magnetic card reading method that makes it possible to effectively utilize data read from a magnetic card inserted into a card reader.

(4) Structure of the Invention In order to achieve the above object, the magnetic card reading method of the present invention includes a magnetic head for reading data on an inserted magnetic card, and a backup memory in which the data read by the magnetic head is temporarily stored. A magnetic card reading device comprising: a detection means for detecting insertion and removal of a magnetic card; the data stored in the buffer memory is held during card insertion and is flushed when the card is removed; It is something to do.

(5) Examples of the invention FIG. 5 is an explanatory diagram of the configuration of an embodiment of the present invention.

In the figure, the difference from Figure 2 is that the card insertion detector 1
This is the second function. That is, the insertion of the magnetic card 10, the presence or absence of a card in the reading section, and the removal of the card are detected.

First, the card 10 is inserted and this card insertion detector 12
When this is reached, the OPU 1 is notified by a card insertion detection signal. As a result, a read command is issued from the OPU 1 to the backup memory 16 as in the conventional case, but it is not reset at the same time. Tsumashi, detector 1
The contents of the backup memory 13 are not reset by the second card presence detection output. The contents of the buffer memory 13 are reset when the detector 12 detects that the card has been removed. Therefore, it is possible for the same operator to execute multiple jobs.

However, if multiple jobs are specified, the CPU
refers to the contents stored in this buffer memory 13,
It becomes possible to confirm the operator. This allows the operator to perform continuous operations over multiple jobs simply by inserting the ID card into the card reader. Moreover, by removing this card,
Since the contents of the buffer memory 13 within the card reader are erased, misuse of the device by a third party can be completely prevented.

(6) As described in detail, according to the present invention, when a magnetic card is inserted into a card reader and read into the backup memory, the read data is retained while the card is inserted and is erased when the card is removed. This is how it was done. This simplifies the operation since the operator does not have to re-enter multiple jobs. When the magnetic card is inserted, it indicates that it is in use, and when it is removed, it is cleared, so there is no problem in maintaining the confidentiality of the ID code.
