Abstract

PURPOSE:To prevent transmission of noise to a talking opposite party by muting the transmission system automatically when the registration mode is executed during talking. CONSTITUTION:When a registration key 19 is operated, a control circuit 23 of a slave set 2 decides whether or not the mode is the speech mode. When the mode is not the speech mode, the control circuit 23 registers data corresponding to the telephone number to an address area designated via a ten-key 16 for an address number, an input registration key 19 in a memory 21. In the case of the speech mode, the control circuit 23 activates a mute circuit 12 to mute the transmission system. When no entry by the ten-key 16 is received and the registration key 19 is operated, the control circuit 23 releases the muting.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device capable of registering a dial number even during a call.

[0002]

2. Description of the Related Art Conventionally, as an automatic dial device, for example, as disclosed in Japanese Patent Publication No. 53-30602, 10 to 30 telephone numbers such as frequently used customer telephone numbers are stored and stored. The dial signal is sent to the line only by making a selection.

In recent years, for example, in order to immediately input a telephone number or the like heard from the other party during a call, the above registration can be performed even during a call.

[0004]

However, as described above,
When the telephone number is registered during a call, the dial circuit operates by the operation of the ten-key pad, which causes noise to be transmitted to the other party of the call, which gives the other party an unpleasant feeling.

[0005]

According to the present invention, there is provided a registration mode for storing a number input by a ten-key pad in a memory,
The telephone device that executes the registration mode even during a call is provided with means for muting the transmission system when the registration mode is executed during a call.

[0006]

Since the present invention is configured as described above, when the registration mode is executed during a call, the transmission system is automatically muted.

[0007]

Embodiments of the present invention will be described with reference to the drawings.

Has been.

FIG. 3 and FIG. 4 are flowcharts of the program of the main part written in the control circuit (23), and the operation will be described based on this. First, a so-called abbreviated telephone number registration mode will be described with reference to FIG. When the registration key (19) is operated, the control circuit (2
3) determines whether or not the call mode is set (step S-
1). Here, the call mode means that a line connection request signal is sent to the master unit (1) by operating the call key (17), and the control circuit (7) of the master unit (1) responds to this by a telephone line (L). ) Is closed.

If it is not in the call mode, the child device (2)
The control circuit (23) is designated through the ten-key (16) input of the address number (00-09) -the registration key (19) input-the ten-key (16) input of the telephone number-the registration key (19) input. Data corresponding to the telephone number is written in the memory area (21) in the address area (steps S-2 to 6).

In the call mode, the control circuit (23) activates the mute circuit (12) to mute the transmitting system (step S-7). This is because the control circuit (23) operates the tone circuit (14) by operating the ten-key pad (16) to generate a key tone from the speaker (10) for a predetermined time (about 0.5 seconds).
3) to prevent it from being sent to the other party,
Even during a call, the control circuit (23) outputs the dial number data in response to the operation of the ten key (16) in order to control the other device through the telephone line (L), so that the dial signal is sent to the other party. To prevent it.

Thereafter, the control circuit (23) monitors the ten-key (16) input of the address number, and at the same time monitors the input of the registration key (19) (step S-8,
9). This is because the registration key (19) is used as a mute key, and when the registration key (19) is operated without the ten key (16) being input, the mute is released (step S-10). Address number numeric keypad (1
6) If there is an input, the registration key (19) input-telephone number ten key (16) input-registration key (19) input is performed after that, as in the case of not in the call mode described above, and the area of the designated address Then, the data corresponding to the telephone number is written in the memory (21) and the mute is released (steps S-11 to 14, 10).

Next, the calling mode of the shortened telephone number will be described with reference to FIG. When the call key (20) is operated, the control circuit (23) of the slave unit (2) monitors the ten-key (16) input of the address number (step S-1).
5) If there is a numeric keypad (16) input, it is determined whether or not the communication mode is set (step S-16). If the call mode is not set, the telephone number data corresponding to the designated address number is called from the memory (21) and the number is displayed on the display (22) (steps S-17, 1).
8). Thereby, the shortened number registration can be utilized as a memo function.

In the call mode, the control circuit (2
3) calls the telephone number data corresponding to the designated address number from the memory (21) and displays the number on the display (22) in the same manner as described above. The data is transmitted to the machine (1) (steps S-19 to 21). As a result, the master unit (1) controls the dial circuit (6) to make a dial call.

[0015]

Since the present invention is configured as described above, when the registration mode is executed during a call, the mute is automatically applied to the transmitting system, which causes noise to the other party of the call. Never send.
