〔Example〕

(A) Before describing the embodiments of the present invention, an example of a communication system proposed by the present applicant in Japanese Patent Application No. 1-154162 (Japanese Patent Application Laid-Open No. 3-19550) will be described.

FIG. 1 is a block diagram showing a configuration example of an electronic data memo pad of a credit card size as a data sending side. 5A is a program memory which is composed of a ROM (read-on memory) and stores processing means described later with reference to FIG. Program memory specified by address decoder 5B
The instruction (instruction) stored at the address 5A is decoded by the instruction decoder 6, and each section is controlled in synchronization with the timing clock. That is, data stored in a data memory 4 composed of, for example, a RAM (random access memory) is sent to an arithmetic logic unit (ALU) 9 via a data bus 10 and arithmetic processing is executed. And re-stored in RAM4. Alternatively, the data stored in the RAM 4 is displayed by a display decoder /
The data is sent to the driver 3 to drive the display 1 and display the data.

Also, detection of operation of the keyboard 2 is requested via the output buffer 8, and when any key operation of a key switch on the keyboard 2 is performed, the signal is taken from the input buffer 7 and the data bus 10 is connected. The data is stored in the RAM 4 via the RAM 4. Then, it decodes the data of No. 3 and executes the processing corresponding to each key according to the processing procedure of the ROM 5A.

Also, the dial data of the RAM 4 is transmitted to the input / output buffer 11 via the data bus 10, and the LED (light emitting diode) 12-
1 to 12-n (n ≧ 1) are driven, exchanged for optical signals, and transmitted. When the detection switch 14 is on, the phototransistors 13-1 and 13-2 are used for data reception and data transmission request control, and the LEDs 12- and 12-2 are used for data transmission and data reception request control. It transmits and receives data with a partner device using a code signal different from that described above.

FIG. 2 shows an example of a transmission processing procedure by the prior application example device. In step S1, the instruction decoder 6 selects and displays data to be displayed on the RAM 4 in FIG. 1 as display processing. Next, it is determined in step S2 whether a key has been input or not. If the determination is No, step S1 is performed.
Return to On the other hand, if it is determined in step S2 that a key input has been made, the instruction decoder 6 executes step S2.
Proceed to S3 to determine what kind of processing the input key performs. For example, if it is determined that the process is in step S5, a process of writing numerical / character data input through another instruction key processing routine in step S4 into the RAM 4 is performed. For example, in the telephone mode state, the name data is input using the character key group 2-3 of the electronic data memo 30 (top view) shown in FIG.
To be displayed. The number data is displayed by using the cursor movement keys 2-4 to move the cursor (not shown) to the numerical data display section 1-.
2 and enter the numerical value input state.
Enter numerical data using.

If it is determined in step S6 that the RA
A process for displaying the data written in M14 on the display 1 in FIG. 1 is performed.

If the dial start key 2-1 shown in FIG. 3 is depressed and the data transmission process is determined, the instruction decoder 6 determines in step S7 what device to send data to, that is, whether the detection switch 14 is on. Determine if
In the case of No, the other party is determined to be a telephone, and in step S10 transmission data (for example, data stored in the RAM 4 in step S6).
The transmission processing (2) is performed for the number data displayed on the display 1-2 out of the data called up on the display 1 in step (1).
Then, it is determined whether the data to be transmitted is completed or not in step S11.
, And if No, the process returns to step 10 to transmit the next data. And it repeats until it becomes Yes in step S11.

The output signal output here is a so-called 2of7 as shown in FIG.
The output signals of the system are output from the LEDs L1 to L7 provided on the back of the electronic data memo 30 shown in FIG.
