Abstract

PROBLEM TO BE SOLVED: To respond to an incoming call after the telephone number of a caller is recognized even at the time of charging by permitting a quick call function to be a non-operation at the time of charging with the display unit of a slave set downward. SOLUTION: When the slave set is charged in a front state, the display equipment is exposed so that the telephone number of the caller is recognized so that a mode is shifted to the call one immediately after the slave set 200 is lifted. On the contrary, when the slave set is charged in a back state, a control circuit 221 permits the mode to be the call one not by the lifting operation of the slave set 200 but only by the operation of a call key 206. When the slave set 200 is charged in the back state, the telephone number of the caller cannot be recognized in the display equipment 208 so that the mode is made to be the call mode by the operation of the key 206 so that the telephone number of the caller is recognized before receiving a phone call. Unless the slave set 200 is charged, a state is shifted to the call one only by the operation of the key 206 naturally.

When there is an incoming call under the calling telephone number display service, the master unit 100 receives the incoming signal and the telephone number judging circuit 11
The data signal of the caller telephone number detected by 0 is transmitted to the child device 200 in a predetermined format. Upon receiving these signals, the control circuit 221 of the child device 200 drives the bell 216 and displays the caller telephone number on the display 208 (S1 to S1).
3). Then, the control circuit 221 of the child device 200 determines whether or not it is in the charging state at that time (S4). At this time, the output of either of the polarity detection circuits 219 and 220 becomes H.
If it is a signal, the control circuit 221 further determines which circuit output is the H signal because charging is in progress, and the control circuit 221 further determines whether the slave device 2
The charge state of 00 is determined (S5). If the mobile device 200 is charged in the state shown in the table, the control circuit 221 causes the mobile device 200 to charge the charging unit 101 based on the output change of the polarity detection circuit 219.
Whether or not it has been lifted is monitored while the incoming call continues (S6, 7). The base unit 100 repeatedly transmits the incoming signal while the incoming call continues. If the caller hangs up the handset and cancels the call, the transmission of the incoming signal from the master unit 100 is stopped, and the control circuit 221 of the slave unit 200 drives the bell 216 and displays the telephone number. It stops (S7, 11).

When the child device 200 is lifted, the control circuit 221 sends a call request signal to the parent device 100 (S1).
0), the control circuit 111 of the base unit 100 which receives this will close the telephone line L (quick call function). After that, the control circuit 221 performs the call processing until the off key 207 is operated, and the operation of the off key 207 transmits the line release request signal to end the call (S12-).
14). Upon receiving the line release request signal, the control circuit 111 of the parent device 100 opens the telephone line L.

That is, when the handset 200 is charged in the state shown in the table as shown in FIG. 3, the display 208 is exposed, so that the caller's telephone number can be confirmed. In addition, it is possible to immediately shift to the call mode by simply lifting the handset 200.

On the other hand, when the slave unit 200 is charged in the back state as shown in FIG. 4, the control circuit 221 causes the slave unit 2 to operate.
The call mode is set only by the operation of the call key 206 instead of the lifting operation of 00 (S5, 8). This is because if the cordless handset 200 is charged in the back state, it is not possible to confirm the caller's telephone number on the display unit 208. Therefore, just by lifting it as described above and immediately setting the call mode, "call I can't answer the request "I want to confirm the other party before leaving." Therefore, the call key 206
The caller's telephone number can be confirmed before receiving a call by setting the call mode by the operation.

If the slave unit 200 is not charged,
Naturally, only the operation of the call key 206 shifts to the call state (S4, S8).

In the embodiment of the present invention, the telephone number is displayed as described above. However, the telephone number and the characters corresponding thereto are registered in advance in the memory in the control circuit 221, and the telephone number from the telephone line is registered. When there is a match in the memory when is detected, characters or the like corresponding to the telephone number may be displayed.

[0020]

Since the present invention is configured as described above, when an incoming call is received, the incoming call can be automatically answered (off-hook) simply by lifting the slave unit from the charger, and the charging of this slave unit is displayed. In the case where the device can be operated either up or down, the incoming call can be answered after confirming the caller's telephone number even when the display device is charged in the downward state.
