FIG. 2 is a block diagram showing a case where the IC card is mounted on the IC card information transmission device according to the present invention, and a case where information is not transmitted. In order to transmit light without performing modulation on both the IC card information transmission device side and the IC card side, unmodulated light is transmitted through the light receiving element 24b of the IC card 2b and the IC card information transmission device 1.
, The information is not transmitted. In FIG. 11, the light modulation element 17b is omitted in the drawing.

At this time, the modulated light passes through the light receiving elements 18a and 18b of the IC card information transmission device 1, but does not perform any operation because the IC card information transmission device 1 is not in a receiving state, and also transmits through the IC card modulation device 23b, but receives the signal. No function is performed because it has no function.

FIG. 13 shows a case where information is transmitted from the IC card 2b to the IC card information transmission device 1. On the IC card information transmitting apparatus 1 side, unmodulated light is supplied to the modulating element 23b in order to perform no modulation, and light modulation is performed by the modulating element 23b based on information from the control device 25b of the IC card 2b. Light is an IC
When the information reaches the light receiving element 18b of the card information transmission device 1 and the information is I
It is transmitted to the control device 14 of the C card information transmission device 1.

At this time, the modulated light is supplied to the other light emitting element 16b of the IC card information transmission device 1, but no action is performed. Further, unmodulated light is supplied to the light receiving element 24b of the IC card 2b, but information is not transmitted.

FIG. 14 is a diagram showing a flowchart of a processing procedure of the control section 14 of the electronic system notebook 1 when information is transmitted from the IC card information transmission device side to the IC card side shown in FIG. 8 or FIG. is there. In step S1, other processes, such as data search and inquiry performed by the electronic system organizer 1, reading of various operation keys 12, display on the liquid crystal display device 13, and the like are performed. In step S2, the IC card 2a, It is determined whether information transmission is necessary in 2b. Step S3 if necessary
To instruct the light emitting element 16a to generate light. In step S4,
Instructs the light modulation element 17a to perform light modulation, and a series of digital information to be transmitted is converted into a series of states of transmitting or blocking light of the light modulation element 17a and output to the IC cards 2a and 2b. . In step S5, it is determined whether or not the transmission of the series of digital information has been completed. When the transmission has been completed, in step S6, the light emitting element 16a of the electronic system notebook 1 is instructed to turn off the light. A series of digital information to be transmitted has a destination code corresponding to the IC card to be transmitted at the beginning, and can be transmitted to one or both of the IC cards 2a and 2b.

FIG. 15 shows that when the optical modulation signal is output from the electronic system organizer 1 to the IC cards 2a and 2b, the respective LSs of the IC card are output.
FIG. 14 is a diagram showing a flowchart of a processing procedure performed by a control circuit built in I25a, 25b. The IC card 2a will be described below. In step S11, other processing such as initial setting for transmitting light through the light modulation element 23a and checking the storage capacity of the semiconductor memory built in the LSI 25a is performed.In step S12, whether or not there is a light modulation signal is determined. That is, it is detected whether or not information is input to the light receiving element 24. If there is information, immediately start reading and step S1
In step 3, the destination codes specific to various IC cards are read, and it is determined whether or not the address is addressed to itself. If not to step S11
If it is addressed to itself, a series of information following the destination code is read and stored and accumulated in the semiconductor memory built in the LSI 25a.

Similarly, for example, to transmit information from the IC card 2a to the electronic system organizer 1, the user operates the keyboard 12 of the electronic system organizer 1 and transmits the information from the electronic system organizer 1 to the IC card 2a.
If the destination code and the information transmission instruction signal unique to the IC card are output as an optical modulation signal, the IC cards 2a and 2b detect whether or not there is information, that is, whether or not the information is input to the respective light receiving elements 24a and 24b. If there is information, the reading is started immediately, and first, it is determined whether or not a destination code information transmission instruction signal unique to itself is output together.

When the optical modulation signal includes a destination code unique to the IC card 2a and an information output instruction signal, the IC card 2a determines this and prepares to transmit information from the IC card 2a. When the output of the optical modulation signal is completed, the electronic system organizer 1 turns off the light emitting element 16a, emits the light emitting element 16b at the opposite position via the IC cards 2a and 2b, and can output the optical modulation signal of the IC card 2a. To do. The IC card 2a knows that the light emitting element 16a of the electronic system organizer 1 has emitted light from the light receiving element 24a, starts modulation of the light modulating element 23a, and outputs a light modulation signal. This light modulation signal is a light receiving element of the electronic system notebook 1.
The information is input to 18a, and the information is transmitted from the IC card 2a to the electronic system organizer 1.

Further, in order to transmit information from the IC card 2a to the IC card 2b, the user operates the keyboard 12 of the electronic system organizer 1 to output the destination code of the IC card 2a and the information output command signal from the electronic system organizer 1 as an optical modulation signal. Then, it outputs the destination code of the IC card 2b and the information input instruction signal as an optical modulation signal.

In order to transmit information from the IC card 2a to the IC card 2b, with respect to the light transmission direction of the light emitting element 16a of the electronic system notebook 1,
First, the light modulation element 23a of the IC card 2a is located, and it is necessary to input the light modulation signal by the light modulation element 23a to the light receiving element 24b of the IC card 2b.

When the IC cards 2a and 2b are mounted in the reverse order with respect to the light emitting element 16a, the light emitting element 17a located at a position opposite to the light emitting element 16a needs to be used as a light source. Therefore, the electronic system organizer 1 needs to first know the relative positions of the IC cards 2a and 2b, and uses the opposite position detection signal from the IC card 2a that has detected the signal instructing the information output as an optical modulation signal for a certain period of time. During the output, the light source of the electronic system organizer 1 is switched from the light emitting element 16a to the light emitting element 16b.

The IC card 2b instructed to input the information receives the relative position detection signal, and can know from the detected timing whether the light source is the light emitting element 16a or 16b.

Next, the IC card 2b outputs this result to the electronic system organizer as an optical modulation signal, and the electronic organizer knows the relative positions of the IC cards 2a and 2b based on this signal, and sets the light emitting source to the light emitting element
If it is determined to be one of the light emitting elements 16b from 6a and a series of information of the IC card 2a is output as an optical modulation signal, the IC card 2b inputs this and the information transmission is completed.

As another embodiment related to the light receiving element of the IC card, as a light receiving element made of a silicon solar cell, it is formed in a pattern pattern on the light modulation element or formed in a thinner thin film form to improve light transmittance. You may have it.
