Abstract

PROBLEM TO BE SOLVED: To prevent storage of undesired caller numbers by avoiding storage of telephone numbers as call reception history whose call reception is rejected. SOLUTION: The telephone set is provided with a caller number detection circuit 12 that detects a caller number, a 1st storage means that stores a caller number detected by the caller number detection circuit 12, a 2nd storage means that stores a registered number and a control circuit 23 that inhibits the 1st storage means from storing the caller number coincident with the registered number stored in the storage means. Thus, telephone numbers whose call reception are rejected are not stored as a call reception history so that the storage capacity is used effectively.

Next, main operations of the master unit (1) will be described.
FIG. 4 is a flowchart showing the operation of the control circuit (23) of the master unit (1). When the control circuit (23) detects the caller number from the caller number detection circuit (12) (Y in S1), the caller number and the date and time of the incoming call are stored in the RAM (25), and then stored in the RAM (25). The comparison is made with all the telephone numbers in the telephone directory stored in 25) (S2). As shown in the flowchart of FIG. 5, the comparison method sequentially compares the numbers of the telephone numbers in the telephone directory excluding the hyphens from the lower digit, and if all the numbers of the telephone numbers in the telephone directory match, the calling party number and the telephone number are compared. It is determined that the phone numbers in the book match. That is, even if the number of digits of the telephone number in the telephone directory is smaller than the caller number, if all the telephone numbers in the telephone directory match, it is considered that the caller number and the telephone number in the telephone directory are the same. As a result, even if the area code is omitted and entered as shown in FIG. 6A, it can be compared with the caller number. In addition, since the telephone number display of the incoming call (step S7 described later) is displayed by the caller number including the area code as shown in FIG. 6B, the user confirms the area code determined to be coincident. can do. If there is a telephone number in the telephone directory that matches the caller number in step S2, and if there is a hyphen in the telephone number in the telephone directory (Y in S3), the control circuit (23) determines the matching part of the caller number. Is replaced with a telephone number in a telephone directory with a hyphen, thereby adding a hyphen (S4) (see FIG. 6). Further, a name corresponding to the telephone number of the matched telephone directory is added (S5). Thus, when the calling party number is displayed in step S7 described later, the phone number becomes easy to read. Next, the caller ID is
A comparison is made with all the telephone numbers of M (25) for which the incoming call notification was rejected (S6). If there is no incoming call rejection telephone number that matches the caller number, the caller may be notified of the incoming call, and the RAM (25) stores the caller number as a call history and a display means (27). To display the caller number, name, and the date and time of the incoming call (S7). Next, the caller number is compared with all the telephone numbers of the special call in the RAM (25) (S8). If no phone number matches the calling number,
The ringing volume is set to the value set by the user, and the color of the backlight of the display unit is set to normal green (S9).
If there is a telephone number that matches the caller number, the calling volume of the master unit (1) and the slave unit (2) is set to be larger than the set value of the user, and the color of the backlight of the display unit is set to a conspicuous red color (S10). ). Next, the caller number is compared with all the telephone numbers of the incoming call notification device in the RAM (25) (S11). If there is no telephone number that matches the caller number, both the parent device (1) and the child device (2) notify of the incoming call (S12). If there is a phone number that matches the caller number, only the master unit (1) or the slave unit (2) corresponding to the matched phone number is notified of the incoming call (S13). Since the data of the special call and the telephone number of the incoming call alert are stored independently, the special call and the incoming call alert are provided for one telephone number, such as the telephone number 03-3333-0001 in FIG. Both can be set. If there is an incoming call rejection phone number that matches the calling party number in step S6, the process proceeds to step S14 without performing the processes of steps S7 to S13. That is, the designated caller number is not notified of the incoming call at all, which is visually the same as the standby state. Therefore, the incoming call to be rejected is not distracted, and the call is not mistakenly made. During the incoming of the telephone number for which the incoming call is rejected, it is possible to perform an operation irrespective of the telephone line, such as registering a telephone directory or rejection of outgoing call notification, and an operation of playing back a recorded message. After Y in step S6, or in step S12 or S1
After 3, whether the handset (15) has been lifted from the mounted state, that is, whether the switch (29) has changed from ON to OFF (S <b> 14), or the telephone device of the caller is on-hook. It is checked whether it has been (S15). If the caller's telephone is on-hook, the incoming call process is terminated (S16). When the switch (29) changes from ON to OFF, the caller number is compared with all the telephone numbers of the incoming call notification rejection in the RAM (25) (S17). If there is no incoming call rejection telephone number that matches the caller number, the call is accepted and the call is processed (S18). If there is an incoming call rejection phone number that matches the caller number, a notification that the phone number whose access is to be rejected is currently being received, for example, “calling incoming call” is displayed ( S19). At this time, the caller number is also displayed. Then, it is determined whether or not the erase key (283) is pressed (S20) or whether or not the telephone device of the caller is on-hook (S21). If the caller's telephone is hooked on, the display indicating that the incoming call notification is being rejected displayed in step S19 is deleted (S22), and the incoming call processing is terminated (S23). If the erase key (283) is pressed in step S20, the RAM
From the incoming call rejection phone number stored in (25), the phone number that matches the caller number is deleted (S24). Then, returning to step S7, the caller number is stored in the RAM (25) as an incoming call history, and the display means (2)
7) displays the caller number, name, and the date and time of the incoming call (S)
7). Then, at step S9, a ringing tone sounds and the handset (15) is lifted again, whereby
It becomes possible to make a call at 16. Thus, when the handset (15) is picked up while receiving a telephone number to reject the call, the fact that the call is being received and the calling number are displayed, and the user sees the calling number and makes a call. When desired, a call can be made by operating the erase key (283).

The telephone number for which the incoming call is rejected is not stored as the incoming call history, so that the storage capacity can be used effectively.
