2. Description of the Related Art Conventionally, there is a technology in telephones for notifying the line number of the other party by voice when receiving a call. For example, in Japanese Patent Application Laid-Open No. Hei 4-306039, a telephone number of a destination is registered in a memory in advance, and when a call is received, the telephone number of the caller is compared with the telephone number stored in the memory. If the telephone number is registered in advance, the corresponding parent device or child device registered in the memory is selected, and the ringing tone is changed from a normal ringing tone to sound from the speaker. In this way, a technology has been disclosed that allows an incoming call from an important specific destination to be determined only by sound. In Japanese Utility Model Laid-Open Publication No. 3-97262, a telephone number of a specific destination is registered in a storage unit in advance, and a telephone number of a caller and a telephone number registered in the storage unit are compared with a telephone number when an incoming call is received. There has been disclosed a technique in which a collation is performed, and when a collation is matched, an audible display is performed, or a collation matching group is visually displayed with a lamp.

In such a conventional technique, the line number is informed by voice, or a lamp indicating that the group is a matching group is displayed by voice. In addition to the problem of disturbing his work, there is also the inconvenience of confidential receiving telephone numbers being heard by outsiders and ending. Conventionally, in a so-called cordless parent-child telephone that is wirelessly connected, the child device is provided with a numeric keypad, and even if a call can be made to the other party, the line number of the other party cannot be displayed when receiving a call.

Next, FIG. 1 will be described in detail. (A) Operation in case of communicating a telephone with a base unit (or a general telephone) Next, an operation in receiving a telephone call with a general telephone or a handset of the main unit will be described. A signal from an external line is supplied to a telephone circuit 2 including a telephone signal processing circuit and a handset via an input / output circuit 1. When an incoming call is received via an external line, a ringing tone sounds, and the line number of the other party is transmitted from the exchange via the external line, the line is stored in the line storage unit 4 by a command from the control unit (CPU) 3. The number is stored. When the handset in the telephone circuit 2 is picked up and the telephone line is turned on (connected), the fact is transmitted to the control unit (CPU) 3. next,
The line number stored in the line storage unit 4 is read from the line storage unit 4 by the control unit 3 and is lit on the numeric keypad display unit 5. At this time, for example, the line number “06-123”
In the case of "-4567", "0", "6", "1", "2", "
The control unit 3 controls the numbers so that the numbers are sequentially turned on at a speed slow enough to allow visual recognition in the order of 3 "," 4 "," 5 "," 6 "," 7 ".
Is set. When the line number makes one round, the line number is lit and displayed again after a short interval. After this is repeatedly displayed three or four times, the display of the line number ends. Thus, the receiver of the telephone can determine who the other party is from the line number. This state is displayed on the numeric keypad display unit 5 as the last four-digit numbers "4" and "5".
, "6" and "7" are as shown in FIG. In this case, the lighting display is preferably performed using an LED element. Reference numeral 8 denotes an operation unit for performing an operation of putting the telephone on hold or switching to the handset.

Next, the operation will be described with reference to the flowchart of FIG. In step (a), it is checked whether or not there is an incoming call. If there is no incoming call to the master unit (No), a standby state is set. If there is an incoming call to the base unit (Yes), the process proceeds to step (b), the ringing tone is sounded by both the base unit and the handset by the calling signal, and the line number of the destination transmitted from the external line to the base unit is controlled. It is stored in the line storage unit 4 according to a command from the unit 3. Next, proceeding to step (c), the line number stored in the line storage unit 4 is read out from the line storage unit 4 according to a command from the control unit 3 and transmitted from the transmission / reception unit 6 of the master unit via the antenna 7 to the slave unit. Sent to On the slave side, the line number of the other party is received together with the call signal, and the line numbers are sequentially displayed on the numeric keypad display 14 of the slave at such a speed as to allow visual confirmation.
Next, the handset side listens to the ringing tone, and operates the operation unit 11 so that the handset can receive a signal. The transmission / reception unit 6 on the master unit side is notified wirelessly. Then, step (d)
The signal transmitted via the external line in accordance with the instruction of the control unit 3 of the master unit is transmitted from the antenna 7 via the transmission / reception unit 6 of the master unit to the antenna 9 of the slave unit by radio waves, and transmitted to the external destination. And communication between the handset and the handset. Next, when the line of the other party or the slave unit is disconnected, a line end signal is transmitted to the master unit, and the master unit also enters the line end state.

Next, as another embodiment, the line number of the other party received by the master unit is transmitted to the slave unit via the antenna 7 without being stored in the line storage unit 4 of the master unit. May be stored in the line storage unit 13 on the side. In this case, the line storage unit 4 on the master side can be omitted. At this time, the line number of the other party transmitted via the external line and the master unit is stored in the line storage unit 13 according to a command from the control unit 12 of the slave unit, and then read from the line storage unit 13 by the control unit 12. Is displayed on the numeric keypad 14 in the same manner as described above. Further, the line number once stored in the line storage unit 13 of the slave unit is read out at a speed at which the line number can be visually recognized in accordance with an instruction from the control unit 3, and is displayed on the numeric keypad 14.
