Next, with reference to the accompanying drawings will be described the operation of the device according to the present invention having the above configuration.

3 is a flowchart illustrating a process of switching the operation mode of the telephone-side microprocessor 120 when the function selector 132 is pressed by a user. First, the microprocessor 120 has a potential at the connection terminal 200. On the basis of the level, if the connection to the expansion memory device B side is frequently checked (STI), and when it is confirmed that the connection is established, the power supply status confirmation data applied from the expansion memory device B side is displayed through the display unit 10. Output (ST2).

As shown in FIG. 4, when the user presses the function selector 132 while the expansion memory device B is connected to the telephone A-side connection terminal 200, the telephone-side microprocessor 120 After confirming that the function selector 132 has been pressed (ST3), it is determined whether the phone is currently in the ON HOOK state (ST4) bar OFF (that is, in a busy state, When the function selection key 132 is pressed, an error (ERR) message is output (ST5) through the display unit 10, and when the function is not on a hook, that is, during a call, the function selection key 132. After the display unit 10 indicates that is pressed (ST6), the operation mode is switched to the extended memory operation mode (ST7), so that the user can save and read the data inputted through the keypad 13. The control target is switched to the expansion memory device, not the internal memory.

Looking at the processing of the voice data proceeds in more detail as follows.

The voice to the user is converted into an electrical signal by the transmitter 52 or the microphone 81 provided in the handset 5 and applied to the network circuit 7, and the voice signal applied by the network circuit 7. After amplification or the like is executed, the codec 17 is outputted to a codec 17 connected to a later stage. The codec 17 codes an audio signal of an analog form applied from the network circuit 7 Convert to a digital signal.

The voice signal converted into the digital signal through the above process is applied to the switching circuit 19 through the digital signal processing processor (DSP) 18, the microprocessor 120 is a switching circuit 19 When controlled, the digital audio signal is switched to the connection terminal.

Next, a control operation during data storage of the microprocessor 201 on the side of the dean memory device B will be described with reference to the flowchart of FIG. 5.

The microprocessor 201 first checks whether the microprocessor 201 is in a state of being electrically connected to the telephone A side based on the potential level of the connection terminal 200 (ST301). Based on the level potential of a predetermined detection terminal (not shown) connected to the power supply state check data is transmitted to the charge side microprocessor 120 as described above (ST302), and then the phone side microprocessor 120 When there is no data input from the server (ST303), if there is data to be transmitted, it is stored in the data memory 203 (ST304). If there is no data to be transmitted, the current connection state is checked (ST305). Stand by until

Although the signal transmission between the two microprocessors 120 and 201 is not shown, for example, by using the I ² C bus, the connection between the two devices and the data transmission can be confirmed.

Since the process of reading the voice data stored in the data memory 203 on the expansion memory device (B) side through the above process is a general process in which the telephone-side microprocessor 120 proceeds in the reverse order when the user stores the same. The detailed description thereof will be omitted.
