FIG. 4 is a flowchart of the main part of the program of the control circuit (24) of the handset (2), and the operation will be explained below based on these.

[0015] First, a case will be described in which the slave unit (2) is placed on the base unit (1) and is being charged. Furthermore, at this time,
Control circuit (11) from each charging terminal (10) (22)
(24) is given an H level signal. here,
When you lift the handset (2) to make a call, the level of the charging terminals (10) and (22) changes from H to L.

) sends a line connection request signal to the base unit (1), while the control circuit (11) of the base unit (1) sends a line connection request signal to the base unit (1) for 5 seconds.
Monitor the line connection request signal from (step A-2~
5. Step B-1, 11). If for some reason the line connection request signal cannot be received within 5 seconds, the base unit (
The control circuit (11) of step 1 shifts to monitoring the charging terminal (10) again. In addition, in step A-2, a change in the terminal level (H→L) is detected, so in this case, once the slave unit (2) is placed on the base unit (1), it cannot be lifted again. and does not move to the next step. Then, the main unit (
When the control circuit (11) of 1) detects a line connection request signal, the control circuit (11) closes the telephone line (L) using the line connection circuit (4) and connects the line to the handset (2). A completion signal is sent (steps A-6, 7). Control circuit (24) of handset (2) that detected this line connection completion signal
drives the LED lamp (21) and presses the call key (19).
) to remind the user that dialing is now possible (steps B-12 and 13). By the way, in this state, from the parent device (1) to the child device (2)
When the handset is lifted and used, the handset (2) is usually used next to the base unit (1), so the dial operation on the handset (2) is disabled and the dial operation on the base unit (1) is enabled. ing. That is, dial operation monitoring processing (steps A-8 and 9) is performed only on the base unit (1) side. This is because the shape of the handset (2) is severely restricted due to its portability, and the shape of the numeric keypad (18) must also be made small, but the base unit (1) has more restrictions in terms of shape than the handset. Because it is small, the shape of the numeric keypad (8) can be made relatively large, resulting in good operability. Also, the cordless handset (
When dialing from 2), the next step is required as explained above.

■Place the handset of the handset to your ear to check the dial tone. ■ Pull down the handset and operate the dials.

[0017] ■ Pick up the handset and enter the talking state. However, when dialing on the base unit (1), you can switch to a call state from step ① without pulling down the handset (2), which provides good operability, and has the added advantage of being able to confirm the dial tone. be. In addition, dial operations on both the base unit (1) and slave unit (2) are not enabled.
This is because dial operations may conflict due to an erroneous operation, and in this case, there is a high possibility that an erroneous dial call will be made.

Then, when a dial operation is performed on the base unit (1) side, the control circuit (11) of this base unit (1) activates the dial circuit (6) to dial the telephone line (L). A signal (tone or pulse) will be sent out (steps A-8, 9). After this, if the user of the handset (2) decides to talk away from the base unit (1), there is no possibility that someone else may operate the numeric keypad (8) on the base unit (1) and interfere with the call. If you want to disable the dial operation on the base unit (1) in order to prevent this, please operate the disable key (9) on the base unit (1) or the call key (19) on the handset (2). (Step A-12, Step B-14).

That is, when the invalidation key (9) is operated, the control circuit (11) of the master unit (1) sends a switching signal to the slave unit (2), and then proceeds to step A-14. Then, the dial operation monitoring process in steps A-8 and A-9 is stopped, and the dial data signal from the handset (2) is monitored (steps A-12 to A-15). On the other hand, the main unit (1
) of the control circuit (2) of the handset (2) that detected the switching signal from
Step 4) moves to step B-5, where the call key (19) is turned on, and dial operations are monitored at steps B-6 and 7 (step B-16). Therefore,
In this way, when the call key (19) changes from flashing to lit, the dial operation on the handset (2) sends a dial data signal to the base unit (1), and the base unit detects this. The control circuit (11) in (1) is the dial circuit (6
) to send a dial signal to the telephone line (L) (Steps A-14, 15, Step B-
6, 7). The reason why dialing operations from handset (2) is made possible in this way is to enable access to various services such as home banking.

Furthermore, when the call key (19) is operated, the control circuit (24) of the handset (2) sends an invalidation signal to the base unit (1) (step B-15), and the process described above is thereafter performed. In the same manner as in step B-5, the call key (19) is turned on and the dial operation is monitored. On the other hand, the control circuit (11) of the base unit (1) that has detected the invalid signal from the slave unit (2) moves to step A-14 in the same way as described above and receives the dial data signal from the slave unit (2). It will be monitored (step A-11).

In the above state, if the off key (20) of the handset (2) is operated or if the handset (2)
) and enters the charging state, and when the output signal from the charging terminal (22) of the handset (2) to the control circuit (24) changes from an L level signal to an H level signal, the control circuit of the handset (2) changes from an L level signal to an H level signal. (24) sends a disconnection data signal to the base unit (1), returns to step B-1, and enters the standby state (
Step B-8, 9, 17, 18, 10). On the other hand, the control circuit (11) of the base unit (1) that has received the cut-off data signal from the slave unit (2) connects the telephone line (
L) is unclosed, the process returns to step A-1, and the standby state is established (steps A-10, 16, 17).

Next, a case will be described in which the slave unit (2) is not placed on the base unit (1) and is in a standby state. To make a call, press the call key (
19), the control circuit (24) of the slave unit (2) sends a line connection request signal to the base unit (1) (step B-2). Base unit (1) that detected this line connection request signal
The control circuit (11) closes the line (L) via the line connection circuit (4), sends a line connection completion signal to the handset (2), and then performs step A-14 in the same manner as described above. Then, the dial data signal from the handset (2) is monitored (steps A-1, 18, and 19).

On the other hand, the control circuit (24) of the slave unit (2) which has detected the line connection completion signal from the base unit (1) lights up the call key (19) and performs the dial operation in the same manner as described above. It monitors and sends dial data signals to the base unit (1) in response to dial operations (Step B-
4-7).

In other words, when the slave unit (2) is not placed on the base unit (1) and is in standby mode, the slave unit (2) is usually placed in a place far away from the base unit (1). Therefore, when making a call in such a case, the dial operation on the base unit (1) is disabled from the beginning, and the dial operation on the slave unit (2) is enabled. It is.

[0025]

Since the present invention is configured as described above, it is possible to make a call from the handset by dialing on the base unit, and it is possible to improve the operability regarding the dialing.

[0026] Furthermore, when a call is made from the handset by dialing on the base unit, subsequent dialing operations on the base unit can be disabled by operations from the base unit or handset. When using a handset, even if another person mistakenly operates a dial key on a base unit, the call on a slave unit will not be interrupted.

[0027]Furthermore, when the handset is placed on the base unit and the call mode is entered, dialing operations can only be performed from the base unit. When the call mode is entered from a state where there is no handset, dialing operations can only be performed from the handset side. In other words, if there is no base unit on the handset side, dialing operations on the handset side are automatically allowed, so there is no need to move the handset to the side of the base unit to perform dial operations. It is very convenient. Since the dialing operation of one of the two terminals is always disabled, it is possible to prevent incorrect dialing due to conflicting dialing operations.
