Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an information transmission means trap for an IC card, and particularly to a user's operation when transmitting key manual data of an IC card with a key input device directly to a terminal side. The present invention relates to an IC card information transmission device suitable for improving performance.

[Conventional technology]

Conventional IC cards do not have electrical contacts and transmit information using light, as described in Japanese Patent Publication No. 60-157626, but the IC card must be inserted into a terminal device and requires key input. When input information from the key input device of the IC card is directly transmitted to the terminal device when the IC card is mounted on a terminal device, it is not possible to operate the key input device on the IC card with the IC card inserted. It was difficult.

[The problem that the invention attempts to solve]

The above conventional technology does not take into consideration the operability when transmitting information from the key input device of the IC card to the terminal device with the IC card equipped with the key input device mounted on the terminal device. I when installed on the terminal device
There was a problem in that it was difficult to operate the C card up key input device.

An object of the present invention is to improve the operability when operating a key input device on an IC card when the IC card with a key input device is mounted on a terminal device.

[Means for solving problems]

In order to eliminate the above-mentioned drawbacks, the present invention arranges a contactless signal input/output device on the back side of the key input device side of the IC card, so that the contactless signal input/output device side is attached to the wall surface of the terminal device. To allow IC cards to be attached so as to face each other, and to allow signal exchange with a non-contact signal input/output device to be performed face-to-face so as to have flexibility in the IC card attachment position of a terminal device. Improved operability can be achieved.

[Effect]

The back side of the key input device side of the IC card is used as a contactless signal input/output device to transmit information using optical signals, and the contactless signal input/output device side of the IC card faces the wall surface that transmits light from the terminal. By attaching it to the IC card, it becomes possible to transmit information between the non-contact signal input/output device on the back side of the IC card and the terminal while operating the key input device on the IC card. In addition, the IC card attachment position of the terminal device can be set to an area larger than the size of the IC card, and the wall surface within that area is set so that the light that passes through the wall surface of the terminal device within that area is focused at a certain point. By having a shape that has the function of a lens, it is possible to give the IC card user more flexibility in the position of attaching the IC card to the terminal, improving operability.

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.

FIG. 1 shows a cross-sectional view of an IC card mounted on a terminal device, where 1 is an IC card, 2 is a substrate made of plastic or glass, 3 is a key input device, and 4 is a sectional view of an IC card mounted on a terminal device.

Either of the magnetic bodies 8 may be a permanent magnet, or the magnetic body 8 on the terminal device side may be an electromagnet. The IC card 1 attached to the wall 1Utl K has an optical signal output device 5 as an optical-to-electrical converter, and a σ-light output device 6 as an electric-to-optical converter are arranged on the board 2. Furthermore, since a key input device 3 is arranged on the board 2 on the side opposite to the side where it is attached to the wall, the IC card user can input the IC card to the terminal device.
It becomes possible to operate the key input device on the IC card even when the card is hot-mounted. The input information from the key input device 3 of the IC card 1 is electrical-to-optical converted and output as light (g) from the optical signal output device 6, and is sent to the focusing lens l0Y.
After ih, an optical signal is input to the light receiving section 12 in the terminal device located at the focal point of the condensing lens 10, and m-information transmission from the IC card 1 to the terminal device becomes possible. Here, power for the IC card is supplied by a solar cell 4 disposed on the substrate 2. In addition, the light emitting unit 11 in the terminal device is replaced by a focusing lens 10.
By placing it at the focal point of the IC card 10 attached to the wall surface of the terminal device, the optical signal from the light emitting unit 11 is outputted to the outside of the terminal device as a parallel beam of light from the wall surface of the terminal device via the focusing lens 10. Transparent substrate 7 to the original signal input device 5
Since the optical signal from the light emitting unit 11 in the terminal device can be input through the terminal device, information transmission from the terminal device to the IC card 1 is also possible. Since the light emitting unit 11 and the light receiving unit 12 in the terminal device are located at the focal point of the condensing lens 1o, the attachment position of the IC card 1 to the wall surface of the terminal device is the same as that of the light-emitting device 1 on the IC card.゛、5. and optical signal output [6 is condensing lens 1o]
Since information Q) can be transmitted even if the IC card is attached in any position and in any direction within the range of Q), it is effective in improving the operability of the IC card user.

First, the magnetic material 8 embedded in the condensing lens 10 of the terminal device is used as a capacitance detector to detect whether the IC card 1 is attached to the wall of the condensing lens or not. When the capacitance change detection circuit 19 detects that an IC card is attached, the control circuit 17 is set to a state in which it can receive an input signal from the terminal device side light receiving section 12. transmit signals to. In other words, noise caused by external light before the IC card is mounted on the terminal device can be completely removed. Attach the IC card to the terminal device and use the key on the IC card! ! 3
When the user inputs information, the signal is input to the control circuit 14, and the control circuit 14 stores the data in the nonvolatile memory 15 or transmits the data to the terminal device, etc., as necessary.
