Abstract

PURPOSE:To easily change a processing algorithm in a portable medium by previously preparing a part which can be electrically connected for processing in accordance with the types of a processing and changing it in accordance with a content. CONSTITUTION:A user selects a connection part having a ROM 17 in which the processing algorithm corresponding to the objective processing is stored among prepared connection parts 9, and it is mounted to a mainbody 7. When a power source is applied to the mainbody 7, a CPU 23 reads the processing algorithm from the ROM 17 and executes a preparing processing required after it is reset, whereby a card 5 is in a connection standby state. When the card 5 is inserted into a connector 11 in such a state, the CPU 23 executes the processing with respect to the memory card 5 in accordance with the processing algorithm which has been read for a host computer. In order to execute other processing after the processing, a required connection part 9 is selected and the similar processing is executed.

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION Field of Industrial Application The present invention relates to a portable media processing device for processing portable media such as IC cards and memory cards.

(Prior Art) With the arrival of a full-fledged card era in the near future, research is underway in various fields on various high-performance portable media such as IC cards and memory cards, and on processing devices for these portable media. Development is actively underway. by the way,
When portable media become widespread in earnest, for example, portable media processing devices will be diverted to other uses for portable media processing, and portable media will be improved! II! L
It is expected that the number of changes to the embedding algorithm will inevitably increase. Therefore, it is important that the portable media processing device has a function that allows the processing algorithm to be easily changed.

(Problem to be Solved by the Invention) Generally, in order to change the processing algorithm, it is sufficient to replace the storage means such as ROM in which the processing algorithm is stored, which is installed in the portable media processing device. In addition to generally being a time-consuming process, this method also requires management of the ROM itself, which is the storage means, that is, the IC itself, which is also troublesome in terms of management.

The present invention has been made in view of the above, and an object of the present invention is to provide a portable media processing device in which the processing algorithm can be easily changed.

[Structure 1 of the Invention (Means for Solving the Problems) In order to achieve the above object, the present invention provides an apparatus that performs necessary processing on a portable medium. The gist of the present invention is that the electrical connection parts are replaceable depending on the content of the process.

(Function) In the portable medium processing device according to the present invention, a plurality of connection parts for electrically connecting the portable medium to be processed so as to be processed are prepared in advance according to the type of processing,
They are replaced as appropriate depending on the content of the process to be executed.

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

FIG. 1 is a transparent perspective view of a portable media processing device (hereinafter simply referred to as "processing device J") according to an embodiment of the present invention;
The figure is a diagram showing the circuit configuration of this processing device 1. As shown in FIG. In addition,
In this embodiment, the portable medium to be processed will be described as a memory card 5 having a connector 3 on one short side thereof, for example.

In FIG. 1, the processing device 1 includes a memory card 5.
The main body section 7 performs processing on the memory card 5, and the connecting section 9 electrically connects the memory card 5 to the main body section 7 when processing the memory card 5.

The connector 9 holds the memory card 5 in the connector 3 during processing, and the memory card connector 11 holds the memory card 5 in the attached and fixed state with respect to the main body 7 and maintains an electrical connection state between the main body 7 and the memory card connector 11. It has a main body connector 13 that holds the main body part connector 13. Both connectors 11 and 13 are connected to the board 15.
The connection terminals thereof are connected via wiring routed on the substrate 15 (see FIG. 2).

Therefore, between these two connectors 11 and 13,
Signals can be exchanged with each other via predetermined wiring, and as a result, signals can be exchanged between the memory card 5 and the processing device 1.

Further, in the connecting section 9, a storage means (in this embodiment, a ROM 17) is mounted on the substrate 15, in which a processing algorithm for the memory card 5 in the main body section 7 is stored. This ROM 17 is connected to the main body connector 13 via wiring on the board 15 (see Fig. 2), and can respond to requests for reading processing algorithms from the CPU 23 of the main body 7 when necessary. There is.

Therefore, as shown in FIG.
By preparing in advance a plurality of ROMs 17, each of which is a connecting part 9 of the configuration, and each having a stored processing algorithm of 51Z, and replacing them as necessary, it is possible to use a single main body part. It is possible to respond to the processing.

The main body part 7 includes a control board 19 mounted with a circuit for executing processing according to a processing algorithm read from the ROM 17 in the connection part 9 to the memory card 5, and a control board 19 mounted on this board 19. It has a connecting part connector 21 that is connected to the main body connector 13 of the connecting part 9 in the dark. As shown in FIG. 2, the circuits mounted on the control board 19 include a CPU 23. RΔ for temporarily storing various data
M25. A transmission interface 27 for transmitting and receiving data with a host computer (not shown). This configuration includes a keypad interface 29 that transmits and receives data to and from a keypad (not shown).

Next, the operation of this embodiment will be explained.

When executing a process on the memory card 5, the user first selects a connection unit 9 having a ROM 17 storing a processing algorithm corresponding to the desired process for the memory card 5 from among a plurality of connection units 9. and attach it to the main body part 7.

Thereafter, by turning on the power to the main unit 7, the CPtJ 23 is reset (loads the processing algorithm from the ROM 17, performs the necessary preparation processing, and enters a standby state for the connection of the memory card 5).

In this state, memory card 5 is connected to memory card connector 1.
1, the CPU 23 executes subsequent processing on the memory card 5 according to the previously read processing algorithm.

Then, when the processing of this memory card 5 is terminated and another processing is to be performed on another memory card 5, the necessary connection section 9 is appropriately selected and the processing is performed in the same manner as described above. , desired processing can be executed on the memory card 5.

Therefore, according to the present embodiment, desired processing can be performed on the memory card 5 by simply replacing the required connecting portions 9 as needed, and the work required to change the processing algorithm is not required. In addition, since the connection unit 9 itself can be viewed as a 1+i adapter equipped with a processing algorithm, it has the advantage that it is easier to manage than the ROM alone.

The processing algorithms stored in the ROM 17 include programming for writing and reading data into and from a portable medium, and when the portable medium is an IC card, an algorithm for data communication with the CPU in the IC card. This includes protocols, etc.

In addition, in this embodiment, the processing target is a memory card, but by preparing a plurality of connectors that correspond to the shape of the connector of the portable medium that is the processing target, the processing target can be a memory card. Of course, it is not limited to cards.

Effects of the Invention As explained above, according to the present invention, a plurality of connection parts for electrically connecting the portable medium to be processed can be prepared in advance according to the processing, and the process can be executed. Since the controller is replaced as appropriate depending on the content of the processing to be performed, the processing algorithm can be easily changed.
