Abstract

In a cordless telephone apparatus including a base unit and a sub unit connected with each other by wireless, the base unit has a memory for storing therein telephone number data which are referred to from the sub unit. When the base unit is busy, the transfer of a calling signal between the sub and base units is not performed. The access from the sub unit to the memory of the base unit is always permitted. The memory includes a callers area in which the telephone numbers of callers of received calls and the reception times of the calls are stored and a directory area in which frequently called telephone numbers and the number of placing calls of the numbers are stored. The telephone numbers in the callers area are retrieved based on the reception times. The telephone numbers in the directory area are retrieved based on the numbers of placing calls. By adding the number of placing calls of the telephone number stored in the callers area to the number of placing calls of the telephone number stored in the directory area, the telephone number retrieval from the directory area functions correctly. Moreover, by using the cordless telephone apparatus as a terminal apparatus of a private telephone system, data stored in a main apparatus of the system are referred to from the sub unit of the terminal apparatus.

Claims

1. A telephone apparatus comprising:

first storing means including an area for storing therein a plurality of telephone numbers and numbers of placing calls corresponding to the telephone numbers;

second storing means for storing at least a telephone number;

a dial transmitting circuit for transmitting a telephone number to a telephone line;

a display for displaying a telephone number; and

a controlling circuit for reading out a telephone number from either of the first and the second storing means and for controlling the dial transmitting circuit to transmit the telephone number to the telephone line, said controlling circuit causing the first storing means to display the telephone numbers in an order of the number of placing calls,

wherein said controlling circuit changes the number of placing calls of a telephone number stored in the first storing means which number is the same as a telephone number read out from the second storing means, based on calling by use of the telephone number read out from the second storing means.

2. A telephone apparatus comprising:

detecting means for detecting a telephone number of a caller transmitted through a telephone line when a call is received;

first storing means for storing a plurality of telephone numbers detected by the detecting means and first numbers of placing calls corresponding to the telephone numbers;

a dial key;

second storing means for storing a plurality of telephone numbers inputted by means of the dial key and second numbers of placing calls corresponding to the telephone numbers;

a dial transmitting circuit for transmitting a telephone number to the telephone line;

a display for displaying a telephone number; and

a controlling circuit for reading out a telephone number from either of the first and the second storing means and for controlling the dial transmitting circuit to transmit the telephone number to the telephone line, said controlling circuit changing the number of placing calls in the storing means from which the telephone number is read out and causing the second storing means to display the telephone numbers in an order of the second number of placing calls,

wherein said controlling circuit has a mode in which data in the first storing means are stored in the second storing means, and in the mode, when a same telephone number is present in the first and second storing means, the controlling circuit adds the first number of placing calls to the second number of placing calls.
