Next, the operation of the system configured as described above will be explained.

[Data indicator] Raise the holder 4 of the parent RA, attach the slave unit B, set both devices to a state where magnetic transfer is possible, and press the keyboard 1 of the parent unit A.
When the control character "CI" is input from , this data is converted into a serial signal by the transmission/reception circuit 18 of base unit A
Figure 7B), coil 31 or l1l-1 of the transmitting/receiving circuit 18
It becomes a magnetic field and is sent toward slave unit B (Fig. 7D).

This magnetic flux is detected by the transmitting/receiving coil of handset B and converted into an electrical signal (Figure A in Figure 8), which is then demodulated into a space mark signal synchronized with the clock by the pulse shaping circuit (
Figure 8E). This signal is converted into a parallel signal by a serial-parallel converter, and is input to the CPU 19 via the data bus 24. The CPU 19 outputs the control character “0”.
1'' determines that it is in the display data transfer mode and starts reception preparations, and after completion of preparation, sends an acknowledgment character ``ACK'' to the base unit A via the transmitter/receiver circuit 18.
Send to. At this stage, the display RAM is
21 sends the start address of the data to be stored and sets the storage address. When data processing is executed by the parent device A after completing such preparations, data generated in the data processing process is sent to the child device via the RAM 12 of the parent device. When the transmission of data is completed, the control character "C10'° is transmitted, and the display address of the data to be displayed blinking on the liquid crystal display panel 27 of the slave unit is transmitted. When all of these data are completed, the master unit Transmission end control character "'X" from A to slave unit B
MT". The CPU 19 of handset B receives this transmission end control character "' If there is an error, it is determined whether or not there is an error, and if there is no error, the affirmative character ``ACK'' is sent to the base unit, and the data is stored in the display RAM 21 and displayed. Negative acknowledgment character “NAK” in some cases.

to request data input again.

[With the slave unit set in the holder of the electronic memo moder base unit 51, input the control character “'C2” from the keyboard l of the base unit.] By inputting this control character "02'', the handset determines that it is in the data storage mode in which the data to be transmitted thereafter will be stored in the data RAM 22, starts receiving preparations, and after completing the preparations, sends an acknowledgment. The character "ACK" is sent to the base unit via the transmitting/receiving circuit 18. At this stage, the base unit transmits the start address of the data to be stored in the RAM 22 of the slave unit to set the storage address, and then,
The data to be stored is sent out one after another. When data transmission is completed, the transmission end control character “X” is sent from the base unit to the slave unit.
MT”. Upon receiving this transmission end control character ”XMT”, the CPU 19 determines whether there is an error in receiving the series of data from C2°′ to , and if there is no error, sends an affirmative character "ACK" to the base unit,
Store the data in RAM22. In addition, if there is an error in receiving data, a negative response character "NAK'"
to request data input again. When data storage is completed in this manner, the child device is removed from the parent device and attached to the wrist. At this stage, when the slave device's button switcher is operated to set the electronic memo mode, the CPU 19 outputs a signal to the RAM 22 via the address data bus 24 to output the stored data to the processing path 24. Data for one screen is displayed on the liquid crystal display panel 27 via the display controller 25. At this time, button switch 7
When is pressed, the data stored in the RAM 22 is output one screen at a time to the liquid crystal display panel 27, the contents are updated one after another, new data is displayed, and desired information can be selected. Further, by operating the button switch 7 to change to the clock mode, the CPU 19 generates a clock signal, functions as a normal digital clock, and displays the time on the liquid crystal display panel 27.

[Data transfer mode] The control character "C3" is sent from the keyboard of the base unit to the slave unit. This allows the slave unit to determine that it is in a mode in which the data sent thereafter will be stored in the RAM 22 by direct memory access. After making a determination and completing preparations for reception, the control character ° "ASK" is sent to the base unit. In response, the base unit transmits the start address of the RAM 22 to be stored by the slave unit, and then the data in the RAM 12 of the base unit is sent. RAM22 of the slave unit
Transfer directly to . When the reception is finished, the peripheral equipment of the handset detects this and interrupts the CPU 19. As a result, the CPU 19 determines that the reception has been completed, checks whether there is an error in the received data, and returns "ACK" if there is no error, or "NAK" if there is an error. ” to request data transfer again. Also, when the parent device sends the control character °C4, the slave device directly transfers the data in the RAM 22 to the RAM 12 of the parent device. After the data transfer is completed, an interrupt is generated, and the slave device transmits the control character "' The state returns to the state before receiving C4".

As explained above, according to the present invention, the system is divided into a base device equipped with a keyboard, a transmitting/receiving means, and a central processing means, and a slave device equipped with a display means, a data storage means, and a transmitting/receiving means. Now that we have configured this, we can configure a full-fledged information processing system by combining the slave unit and the master unit.
・The handset can be used independently as a small, lightweight electronic memo, and at the same time can be used as a data storage medium to easily exchange data with other systems, making it a versatile and effective system. It becomes available for use.
