Next, an operation example of the communication card 10 having the configuration shown in FIG. 2 will be described.

When the power switch of the communication card 10 is turned on, the control routine of the communication card shown in FIG. 4 is repeatedly performed at predetermined time intervals. When this control routine is started, first, it is determined whether or not a link completion flag RNKOK described later is set (RNKOK = 1) (RN
It is determined whether KOK = 0) (step 100). Here, it is at the time of startup, and since all the flags described later are in the initial state “clear state”, the link completion flag RNKOK =
It is determined to be 0, and then the link routine is executed (step 110). In this link routine, first, as shown in FIG.
120). When the process proceeds to the transmission of the link request data, as shown in FIG. 6, it is first determined whether or not the set switch of the operation unit 31 of the communication card 10 is "ON" (step 130). Here, if the set switch is "ON", that is, the switch for starting the input of data and starting communication with the communication card is "ON", then the ROM 2
The link request data is input to the operator according to a preset format based on a program (not shown) stored in the switch 1 (switch 14).
0). As the link request data, for example, the ID code, name, requirement, gender, age, article name, or the like of the partner requesting the link can be considered. After the completion of the input of the link request data, the operator is caused to input data (exchange data) to be exchanged with another communication card (step 150). As the exchange data, for example, a message, an image, various data, and the like to a linked partner can be considered. After the input of the exchange data, the input link request data is wirelessly transmitted via the data transmission unit 40 (step 160). As a result of this processing, the transmission antenna 53 of the communication card 10 performs wireless transmission of the signal shown at the time T0 to the time T1 in FIG. 7 by a data transmission execution routine (not shown). That is,
First, as shown from time T0 to time T0a, its own ID code is wirelessly transmitted, and then, as shown from T0b to time T1,
The input link request data is wirelessly transmitted on the main channel.

After the wireless transmission of the link request data in FIG. 6 described above, a set state (RNKF = 1) indicating a state in which a link flag RNKF described later determines to perform the link as shown in FIG. Is determined (step 17
0). Here, since it has not been set yet, it is determined that it is in the clear state (RNKF = 0), and the process of accepting the next link response data is performed (step 180). The reception of the link response data is performed by first performing a process for setting the data receiving unit 41 to the main channel reception state as shown at time points T2 to T3 in FIG. 7 by a data reception execution routine (not shown). As shown in the figure, the ID code of the data currently received by the data
Input is made from the input 72 (step 190), and then a process of inputting link response data or link request data from the input data buffer 64 is performed (step 200). Here, if the data receiving unit 41 has received the link response data or the link request data from the communication card at the current location, for example, as shown from time T4 to time T5 in FIG.
An ID code of another communication card and link response data or link request data are input and stored in a predetermined area in the RAM 22.

After the execution of the reception of the link response data shown in FIG. 8, the response is determined as shown in FIG.
210). The judgment of this response is, as shown in FIG.
A decoding process of data from another communication card stored in the AM 22 is performed (step 220). Decryption of this data is, for example, whether the response or the requested data requires its own response, whether the requested data is suitable for itself, or whether the response data is in response to its call. And so on.

After the decryption, it is next determined whether or not the response or the request data is directed to itself, or whether or not the data corresponds to itself, so as to determine whether or not to link in response to another communication card (Snap 230). ). If it is determined that the link is made in response, the link flag RNKF
Is set (RNKF = 1) (step 240). If no response is received, the link flag RNKF is cleared (step 250).

After setting or clearing the link flag RNKF in FIG. 10, the link procedure in FIG.
260). In this link procedure, as shown in FIG. 11, it is first determined whether or not the link flag RNKF is set (snap 270). If the link flag RNKF has not been set, this routine is once terminated, and if it has been set, next, wireless transmission of link procedure data is performed via the data transmission unit 40 (step 280). The link procedure data transmitted here is, for example,
It includes an ID code and shift channel data, and is as shown from time T6 to time T7 in FIG. After transmitting the link procedure data, reception of link procedure data acceptance confirmation data from the party to which the link procedure data has been transmitted is next performed (step 290). This is equivalent to the link procedure data transmitted here. That is, the reception of the ID code and the shift channel data from the other party via the data reception unit 41 is performed. After performing the above reception, it is determined whether or not there has been a reception confirmation (step 300). If the acknowledgment has not been transmitted from the other party, the routine of FIG. 11 is terminated at a glance, and if the acknowledgment has been confirmed, a link command is output to the wireless transmission / reception control unit 70 next ( Step 310). The link command shifts the wireless transmission unit 52 to the communication channel 1-A and shifts the wireless reception unit 61 to the communication channel 1-B based on, for example, the shift channel data. The communication card of the other party shifts the wireless transmission unit to the communication channel 1-B and sets the paperless reception unit to the communication channel 1-B.
Shift to A. After performing the link command, it is next determined whether or not the link of the other communication card has been completed (step 320). This determination is based on, for example, that the ID code of the
This is performed by determining whether or not the code is detected by the code detection unit 72. If it is determined by the above determination that the link has not been completed, this routine is temporarily terminated as it is. If the link has been completed, the link completion flag RN
Set KOK and end this routine once (Step 3
30).

After performing the link procedure (step 260 in FIG. 5, routine in FIG. 11), the link completion flag RNKOK described above in FIG. 4 is determined (step 100), and the flag RN is set.
If KOK is not set, that is, if the link has not been completed, the link processing (step 110) is repeated again.

On the other hand, if the link completion flag RNKOK is set, data transmission / reception processing is performed next (step 340). For data transmission / reception, as shown in FIG. 12, data exchange processing is first performed (step 350). As shown in FIG. 13, the data exchange is performed by wirelessly transmitting the exchange data input in FIG. 6 (step 360), and then, the exchange data input to the input data buffer 64 of the data receiving unit 41 from the other end. The exchange data is stored in a predetermined area of the RAM 22 (step 370). This data exchange state is performed, for example, as shown in FIG.

Until the link is completed and the exchange data is transmitted and received, the data transmission unit 40 transmits the ID code and the carrier alternately from the data transmission unit 40 until time T9. On the other hand, the data receiving unit 41
Receives the ID code of the other party and the carrier of the other party alternately.

As shown after time T9, exchange data is transmitted and received, for example, as shown below, the exchange data is transmitted from the data transmission unit 40 following the own ID code, and the data reception unit 41 Following the code, the exchange data of the other party is received.

After the routine of FIG. 13 is performed, the data transmission / reception completion determination processing of FIG. 12 is performed (step 380). As shown in FIG. It is determined whether or not a transmission completion signal of exchange data is included in (step 390).
Next, it is determined whether or not there is a question in the exchange data of the other party requesting a reply (step 400). The transmission completion signal is
For example, when the transmission of all the exchange data is completed, it is attached to the exchange data and sent to the other party. The question for which the reply is requested is, for example, data for which a reply to the exchange data is requested in addition to the simple exchange of the exchange data. For example, this is used when a specific question from a specific party can be answered in advance. For example,
There may be a case where the previous reply is requested again, or a case where a reply is previously determined for a specific question.

If it is determined from the above that there is a question for which a reply is to be made, then it is decoded during this period (step 410), and then it is determined whether this question is undecipherable or not possible to reply to this question (step 420). ). Here, if it is determined that the message cannot be decoded or cannot be answered, for example, because an unexpected question has been included, a message indicating that the message cannot be decoded or cannot be answered is wirelessly transmitted to the other party (step 43).
0) On the other hand, if a reply is possible, the reply is wirelessly transmitted to the other party (step 440).

After sending a reply to the above party (steps 430,44
0), or if a completion signal has been received from the other party (step 390), or if there has been no question from the other party (step 40).
After completing either of the above (0), the ID data and exchange data of the other party are displayed on the liquid crystal display unit 30 (step 450), and then the link flag RNKF and the link completion flag RNKOK are cleared and initialized (step 450). 460), and wirelessly transmit a completion signal to the other party (step 470). Thereby, the link state with the other party is released. In the flowchart of the present embodiment, the following processing is performed as each state elapses.

In the link request data transmission processing of FIG. 6, after the input of the link request data (step 140) and the input of the exchange data (step 150), the above processing is passed by the determination of step 130.

After the exchange data and the like are input and the link flag is set in the same manner as described above, the snap 480 and the step 170 in FIG. 5 cause the step 160 in FIG. 6 and the snaps 180 and 210 in FIG. Passed.

Until the link completion flag RNKOK is set and the link with the other party is completed, the link processing of FIG. 4 is passed in step 100 of FIG. 4, and the data transmission / reception processing (step 34)
Only 0) is repeated.

As described above with reference to the embodiment, the communication card of the present embodiment automatically exchanges data with another communication card based on its own function. As a result, for example, as shown in FIG.
Alternatively, it is possible to freely exchange data selectively between the card F and the cards D, C and B. Thereby, an extremely excellent effect as described below is obtained.

For example, data can be exchanged with a specific partner.
That is, by applying this to a toy, the following effects can be obtained. For example, by using it for message play or the like, it is possible to automatically make a promise of play between friends. Alternatively, you can send a message to someone who is about to become a friend and receive a reply.

For example, it is possible to select a person who has data or the like that satisfies his / her needs from an unspecified number of people, and exchange data with each other. Thus, barter data can be exchanged with this card. In other words, those who want something transmit their own data, while those who do not need send their unnecessary data. This can be achieved by receiving the transmission data of each other, linking with the card, and exchanging the exchange data.

You can also choose who you want with this card. That is, it is possible to transmit the data of the person who seeks each other and find the person who seeks. Thus, for example, it is possible to automatically find a job offer, a job offer, a bath, and the like.

Note that the present invention is not limited to the above-described embodiment, and various embodiments can be implemented. For example, by selecting the wireless transmission / reception unit according to the application, the transmission / reception area can be adjusted and more appropriate operation can be performed.
