Abstract

PURPOSE:To simplify operation procedures without complexing a device by reading out information stored in a portable storage medium and switching the processing of a processing part on the basis of the read information. CONSTITUTION:An IC card 1 is a card to be exclusively used for switching to test processing and data is stored in a historical character part, i.e. an initial response, in answer-to-reset to be used for data transmission on a circuit substrate. When data '1' is stored in the initial response, a reader/writer part 3 is switched to test processing, and when '0' is stored in the initial response, the test processing is switched to normal processing. When the IC card is ejected from a card insertion port 5, the reader/writer part 3 reads out stored data and the device is switched to the test processing or normal processing in accordance with the read data. Consequently, operation procedures can be simplified without complexing the device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Application Field) This invention relates to a portable storage medium processing device having a processing section that is switched to various processing by a switching operation.

(Prior Art) A conventional portable storage medium processing device will be described with reference to a perspective view in FIG. 3 and a bottom view in FIG. 4. The processing section 7 having the shape of a rectangular parallelepiped has a built-in circuit board 9 having the shape of a thin film type rectangular parallelepiped, for example.

This circuit board 9 is provided with a memory that stores a control circuit for controlling various types of the processing section 7 and a test program for testing the processing section 7 at a predetermined address. A changeover switch 11 is provided at the bottom end of the circuit board 9 for switching the processing section 7 between normal processing such as data transmission to the host side (not shown) or test processing for checking the transport status of the inserted card. We are prepared. To switch the processing section 7 having the above configuration from normal processing to test processing, the power to the processing section 7 is once turned off, the selector switch 11 is switched to the test mode side, and the power to the processing section 7 is turned on again. This operation causes the devices provided on the circuit board 9 to be reset and initialized, and the processing section 7 to switch to test processing.

Conventionally, switching the processing section 7 to test processing has required time and effort as described above.

(Problem to be Solved by the Invention) In the conventional portable storage medium processing device, in order to switch the processing section 7 from normal processing to test processing, the power must be turned off, the power must be turned on, and the changeover switch 11 must be operated. Therefore, the operator is burdened with switching operations. As a countermeasure, it may be possible to automate the switching operation of the processing section 7 to test processing, but this automation requires the installation of various control circuits, etc. There was a fear that ICs would become larger, and countermeasures were desperately needed.

The present invention has been made in view of the above, and an object thereof is to provide a portable storage medium processing device that simplifies operating procedures without complicating the device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a portable storage medium that stores information for switching the processing of a processing unit that performs various processing; The present invention further comprises a switching means for reading information stored in a portable storage medium and switching the processing of the processing unit based on the read information.

(Operation) In order to achieve the above object, the present invention provides that when a portable storage medium storing information for switching the processing of the processing section is inserted into the processing section, the processing section will switch the processing of the processing section. Since information is read and processing is switched based on the read information, the operating procedure can be simplified without complicating the device.

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

FIG. 1 is a schematic diagram showing an embodiment of a portable storage medium processing device of the present invention.

The IC card (portable storage medium) 1 is a card dedicated to switching to test processing, and has a built-in circuit board (not shown) that stores historical characters in the answer-to-reset used for data transmission. Data is stored in a so-called initial response. This initial response data is used to switch the reader/writer unit 3, which will be described later, to test processing if it stores data of "1", and if "O" is stored in the initial response, it switches from test processing to normal. This indicates that the processing will be switched to.

When the IC card 1 is inserted from the card insertion slot 5, the reader/writer unit 3 (processing unit) reads the data stored in the IC card 1, switches to test processing or normal processing according to the read data, and performs the processing. It is something that does. The reader/writer unit 3 has a built-in circuit board (not shown) on which a memory storing test programs and the like is mounted.

This circuit board is equipped with a device having a function of converting processing modes, etc., and the test processing is switched based on the initial response data stored in the IC card 1. Here, the test processing includes, for example, testing the processing of measuring the transport status of the IC card 1, transmission control such as reading data stored in the IC card 1, transmission control with the host side (not shown), etc. It is something to do. Also,
The reader/writer section 3 responds to a command transmitted when data is transmitted from the host side, for example, if the command is
When writing data to the C card 1, the data writing process is performed via the contacts of the IC card 1. Further, if there is no data transmission from the host side, the reader/writer unit 3 checks whether the IC card 1 is inserted, and reads the initial response data of the IC card 1 if the C card 1 is inserted. Based on the read data, the read/write section 3 switches the processing. That is, if the initial response of the IC card 1 is ``1'', the process is switched to test processing, and if the initial response is ``O'', the IC card 1 is ejected from the card insertion slot 5.

Next, the operation of this embodiment will be explained using the processing flowchart shown in FIG.

First, when power is applied to the reader/writer unit 3, the reader/writer unit 3 initializes the device after resetting the device mounted on the circuit board (steps 100 to 3).
110).

When the device initialization is completed, the reader/writer section 3 checks data transmission from the host side.

When data is transmitted from the host side, the reader/writer section 3 responds to the transmitted command, for example, if the command is
If the command is to write data to the C card 1, if the IC card 1 is inserted and data can be written, the write process will be performed. After completing the infiltration, transmit the end response. on the other hand,
If the data cannot be written to the IC card 1, the reader/writer section 3 sets an error response and transmits it to the host side.

When the above processing is completed, the reader/writer section 3 returns to the state of waiting for reception from the host side. On the other hand, if there is no data transmission from the host side, the process advances to step 140 (step 12
0-130).

Proceeding to step 140, the reader/writer unit 3 checks whether the IC card 1 has been inserted from the card insertion slot 5 by the user. If the IC card 1 is not inserted, the process returns to step 120, where it waits for reception from the host side. On the other hand, if the IC card 1 is inserted from the card insertion slot 5, the reader/writer unit 3 turns on the power to the inserted IC card 1 (steps 140 to 150).

When power is applied to the IC card 1, the reader/writer section 3
The initial response built into the IC card 1 is read.

If the initial response data is "1", the reader/writer unit 3 performs test processing such as reading or writing data to the IC card 1, and after the processing is completed, returns to the state of waiting for reception from the host side in step 120. On the other hand, if the initial response of the IC card 1 is "O", the reader/writer section 3
Eject card 1 from card insertion slot 5 and step 120
The computer waits for data transmission from the host side (steps 160 to 180).

Since the reader/writer unit 3 can be switched to test processing by the above-mentioned action, there is no need to provide the changeover switch 11 in the reader/writer unit 3 as in the past, and there is no need to operate the changeover switch, making the device complicated. The switching operation can be simplified without having to do so.

This embodiment is not limited to an IC card, but may also use a magnetic card or the like for storing data.

Further, this embodiment can also be applied to a device that switches between various types of processing.

[Effects of the Invention] As explained above, according to the present invention, when a portable storage medium storing information for switching the processing of the processing section is inserted into the processing section, the processing section changes the information stored in the portable storage medium. Since the information read is read and the processing is switched based on the read information, the operating procedure can be simplified without complicating the device.
