Next, the operation of the above embodiment will be described.

FIG. 3 is a flowchart showing the operation of the above embodiment.

First, when the power of the slave unit 10 is turned on (S
2) The child device 10 reads the contents of the memory 16 and
It is determined whether the state is already registered (S3). If the child device 10 has already been registered in the parent device 20, it shifts to a waiting state as a normal operation (S4). If the parent device 20 as the communication partner is not registered, the information of the connection detection unit 10D is read, and it is determined whether or not the information processing device 40 to which the child device 10 is connected is connected. A determination is made (S5). If it is determined that it is not connected to the information processing device 40 (S5), the flow returns to the start state of the flow.
If it is determined that it is connected to the information processing device 40 (S
5), the child device 10 shifts to the registration mode (S6). Note that the registration mode is a mode in which registration can be performed to enable communication with the master unit.

The slave unit 10 that has entered the registration mode operates the receiving unit 11R to search for a notification signal from the master unit 20 that is in the registration mode. If there is no parent device 20 in the registration mode, an error is displayed after a lapse of a predetermined time (S8) (S13).

When there is a master unit 20 in the registration mode (S
7), a registration sequence is started (S9), and the sequence is advanced while determining in the sequence whether or not the partner to be registered by master device 20 is itself. If the sequence is stopped because necessary information is not received from the master device 20 or the like and the registration is not completed even after a certain time has elapsed (S12), an error message is displayed and the process is terminated (S13).

When the registration is completed normally (S10), the process ends (S11). When the process is normally completed (S11), the master device 20 and the slave device 10 can store information such as an ID number that each has uniquely in the memory 16, and thereafter,
The registered parent device 20 and child device 10 can communicate without interference.

Next, the same operation as the operation shown in FIG.

Here, the base unit 20 is provided with a keyboard as an operation unit, or a keyboard can be connected to the outside. In the following description, it is assumed that the keyboard is connected. It also has a display unit for displaying the progress of the registration sequence.

When the power of the child device 10 is turned on (S21), if it is determined that the child device 10 is not registered with the parent device 20 and is not connected to the information processing device 40, Slave device 10 starts waiting for automatic registration (S22).

When an operation to shift to the registration mode is performed from the keyboard of the base unit 20, registration is started (S2).
3) When this registration is started, "SOMODE" indicating that the mode is the registration mode is displayed (S24), and then the user is prompted to input the extension number of the slave unit 10 to be registered. “PSNo?” Is displayed (S2
5).

Here, the operator inputs the number of the child device 10 to be registered. In FIG. 4, it is assumed that the registration is made as the eleventh. After inputting the PSNo (S26), "PSID?" Prompting the input of a password is displayed (S2).
7). Here, when a plurality of slaves 10 are in the registered state, the ID of the slave 10 is input as a password in order to prevent unintended slaves 10 from being registered. FIG.
Then, 123456789 is input as the ID of the child device 10.

When a PSID as a personal identification number is input (S28), "RUN" meaning that a registration operation is being performed.
NING "is displayed (S29), and base unit 20 transmits a notification signal for registration (S30). The child device 10 that has received this notification signal executes a registration sequence with the parent device 20 (S31).
"COMPLETE" indicating the end of registration is displayed on the display unit (S32).

By performing the above-described operation, the parent device 20 can be registered even with the child device 10 having no operation unit.
