Abstract

PURPOSE:To provide a long life IC card by enabling a connector part to be connected to the outside to be easily exchanged by a user. CONSTITUTION:Storage elements 12 such as ROM, RAM, etc., control circuit elements 13 controlling those storage elements, a cell 14, etc., are arranged on a substrate 11, and a connector 15 fixed to the substrate 11 is provided. Then, an on-off-free connector 16 not to be fixed to the substrate 11 is fitted into the connector 15. This connector 16 is connected directly to the outside. An IC card of which the connector can be easily exchanged where poor contacting and others by breakdown and abrasion of the connector occur, is obtained.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card having a replaceable connector connected to the outside.

0002

2. Description of the Related Art Generally, an IC card is constructed as shown in the top view of FIG. 2(a) and the side view of FIG. 2(b).
A storage element 2 such as a ROM or RAM, a control circuit element 3 for controlling these storage elements, a battery 4 for supplying power to drive these elements, and the like are arranged and wired above. Furthermore, a connector 5 is provided on the substrate 1 and is fixed to the substrate 1 by soldering for connecting with an external circuit and transmitting and receiving data signals and the like. This substrate is sealed in a card-shaped container, called an "IC card," and used for various purposes.

[0003] Since this IC card is mainly constructed using semiconductor integrated circuits, if the battery is replaced,
It can be used for quite a long time.

0004

[Problems to be Solved by the Invention] However, in the conventional IC card described above, the connector for connecting to the external circuit uses a connection method that cannot be easily removed, such as by soldering to an electrode on the board. and is fixed to the substrate. The contact portion of the connector made of a conductor is exposed from the container or exposed during connection.

[0005] Therefore, each time an IC card is used, it is repeatedly inserted and removed to attach it to an external device, and the more frequently it is used, the more the contact portions are worn out, shortening the lifespan of the IC card. In addition, due to user carelessness, the contacts of the connector may be soiled or clogged with foreign matter, and if the connector is defective or damaged, the I/O
C card is unusable.

[0006] Therefore, the present invention provides an I/O device that allows the user to easily replace the connector portion that connects to the outside, and has a longer service life.
The purpose is to provide C cards.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a recording means for recording data, a control means for controlling the recording medium, and a power source for supplying power to the recording medium and the control circuit. a supply means, a board on which each of the above means is mounted and provided with a plurality of electrodes for transmitting and receiving signals with the outside, a first connector in which a contact is connected and fixed to the electrode of the board; An IC card is provided, comprising a second connector detachably mating with the first connector, and connected to an external circuit via the second connector.

[0008]

[Operation] In the IC card of the present invention having the above-described structure, if a problem occurs in the second connector, the second connector can be pulled out from the fixed first connector and removed.

[0009]

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the structure of an IC card as an embodiment of the present invention, with FIG. 1(a) showing a top view and FIG. 1(b) showing a side view.

[0011] In the IC card, a memory element 12 such as ROM or RAM, a control circuit element 13 for controlling these memory elements, and a battery 14 for supplying power to drive these elements are mounted on a substrate 11 made of an insulator. placed and wired respectively.

Furthermore, a plurality of electrodes 17 are provided on the substrate 11 for transmitting and receiving control signals, data signals, etc. between the external circuit and each circuit. One of the plurality of contacts 15a is connected to these electrodes 17 by soldering or the like, and a connector 15 fixed to the substrate 11 is provided. A detachable connector 16, which is not fixed to the substrate 11, is fitted to the other end 15b of the connector 15.

The connector 16 is directly connected to the outside, and the connector 16 and the connector 15
Control signals, data signals, and the like are transmitted and received between the external circuits and the aforementioned circuits via the circuit.

Furthermore, in the event that the connector 16 is damaged or has poor contact due to wear, it can be easily removed by opening the case (not shown), pulling it out from the connector 15, and replacing it. Further, the connector 16 may be fixed to the connector 15 or the substrate in a mated state by screwing.

As detailed above, the IC card of the present invention allows the user to easily replace the connector with a spare equivalent connector when the connector is damaged or has poor contact due to wear, and can be used immediately. Can be done. Moreover, since you only need to replace the connector, it is possible to connect the RA from the battery.
The power supply to M is not stopped, and the stored information is maintained as is.

Further, the present invention is not limited to the one embodiment described above, and it goes without saying that various modifications and applications can be made without departing from the gist of the invention.

[0017]

As described above, according to the IC card of the present invention, the connector connected to the outside can be easily replaced by the user, and the life of the IC card can be extended.
