Abstract

PURPOSE:To prevent reply of other person not reserved to the telephone by operating an automatic dialing notice means to inform the automatic dialing to the user, and applying automatic dialing to a number stored in advance after off-hook is detected. CONSTITUTION:In receiving an input from a line state detection means 19, an automatic dial means 21 detects whether or not terminal telephone sets 1-3 applying automatic dial reservation through the input from an off-hook detection section 12 is detected and in the state of on-hook, a reservation call is generated from a reservation call generator 15. The off-hook of the terminal telephone sets 1-3 reserving dial is detected and when the operation of a specific button 27 is detected, an exchange 9 is switched and a number stored in a dial memory 13 is sent telephone lines 5, 5 via the exchange 9 from the dialer 14 to the telephone lines 5, 5 to apply automatic dialing. Thus, the reply of other person not reserved to the telephone is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic dialing system for an automatic dialing device that can automatically dial a pre-stored number.

(Summary) The present invention provides automatic dialing by operating an automatic dialing time notification means in an automatic dialing system of an automatic dialing device that can automatically dial a pre-stored number. The system notifies the user and automatically dials a pre-stored number after off-hook is detected.

(Prior art) The automatic dialing system that has been commonly used in the past is such that when the called party is busy or the telephone line is full, the caller enters the number of the other party and operates an automatic dialing button. When a call ends or the telephone line becomes vacant, the system automatically dials a stored number to call the other party, and also rings the caller's bell to notify the user that an automatic call has been made.

(Problem to be Solved by the Invention) However, with the above-mentioned conventional automatic dialing system, when an automatic dialing is made, the other party is automatically dialed and the other party is dialed, and the calling party also receives the same ring tone as when the call is normally received. Because the system was designed to notify the user that automatic dialing had been performed, there was a risk that someone other than the person who made the reservation would answer the call.

Means for Solving Problem C) The present invention aims to eliminate the above-mentioned drawbacks of the conventional system, and provides off-hook detection means and notification means for notifying the user of automatic dialing.

(Function) At the time of automatic dialing, the user is notified with a ringing tone different from the normal ringing tone, and when off-hook is detected, a pre-stored number is automatically dialed.

(Example) Hereinafter, the present invention will be described in detail according to an example shown in the drawings. In FIG. 1, 1 to 3 are terminal telephones, 4 is a main device that controls the terminal telephones 1 to 3, and 5.5 is a telephone line. An idle line detection unit 10 detects whether the telephone line 5.5 or extension 6 is vacant, an extension busy detection unit 11 detects the call status of the terminal telephones 1 to 3, and a detection unit 11 detects whether the terminal telephones 1 to 3 are off-hook during automatic dialing. an off-hook detection unit 12 that detects whether the phone number is off-hook, and a dial memory 13 that stores the telephone number of the other party.
, a dial transmitter 14 that sends out the number stored in the dial memory 13 during automatic dialing, a reserved call generator 15 that notifies the caller during automatic dialing, and a control section 16 that controls each of the above components. ing. The control unit 16 also includes a reservation detection means 17 for detecting an automatic dial reservation, and a dial detection means 1 for detecting the number of the destination to be automatically dialed and storing it in the dial memory 13.
8, line status detection means 19 for detecting the idle status of telephone port ff55.5 and extensions 6 to 8, timer means 20 for regulating the operation time of the reserved call generator 15, and a timer means 20 for regulating the operating time of the reserved call generator 15, and a timer means 20 for regulating the operating time of the reserved call generator 15, Automatic dialing means 21 are provided for automatically dialing a number.

FIG. 2 is a plan view of the terminal telephones 1 to 3, and on the cabinet surface of the telephones 1 to 3, there is a handset 22.
, line selection buttons 23, 23, . . ., line status display lamps 24, 24, . . ., a 12 key 25, an automatic dial reservation button 26, and a specific button 27.

Next, the operation of the automatic dialing system according to the present invention will be explained according to the flowchart shown in FIG.
．． To explain when making a call using 5,
The line status display lamps 24, 24, etc. provided on the main bodies of the telephones 1 to 3 determine whether the telephone line 5.5 is free (step ■), and when the line is free, it goes off-hook and makes a normal call. , If there is no vacancy, operate the automatic dial reservation button 26 (step ■) and enter the recipient's number using the L and 12 keys (step ■), and the reservation detection means 1
7 detects that the reservation button has been operated, and drives the line status detection means 19 and automatic dialing means 21,
The input number is stored in the dial memory 13 via the dial detection means 18. Then, the idle line detection unit lO
When it is detected that the telephone line 5.5 is vacant (step ■), the automatic dialing means 21 is activated via the line status detecting means 19.
When the automatic dialing means 21 receives an input from the line status detecting means 19, the automatic dialing means 21 detects the terminal telephone that has made an automatic dialing reservation based on the input from the off-hook detecting section 12.
It is detected whether or not the devices 1 to 3 are in the off-hook state (step ■), and if they are in the on-hook state, the reservation call generator 1
5, a reserved call is generated (step 2), and the timer means 20 is operated to measure the time from the start of the reserved call generation (step 2). Thereafter, off-hook of the terminal telephones 1 to 3 reserved for automatic dialing is detected within the time set by the timer means 20 from the start of the reservation call occurrence (
Step ■), and when it is detected that the specific button 27 has been operated (Step ■), the exchange 9 is switched and the number stored in the dial memory 13 is transmitted from the dial transmitter 4 via the exchange 9. and sends it to the telephone line 5.5 (
Step ■) and it will automatically dial.

Next, when making a call to extensions 6 to 8, if the other party's terminal telephones 1 to 3 are busy, the above telephone line 5
．． Operate the automatic dial button 26 in the same way as when using 5.
By inputting the telephone number of the other party using the 12 key 25, automatic dialing can be performed in the same manner as described above.

Therefore, in the above embodiment, a special ringing tone different from the normal ringing tone is generated, and automatic dialing is performed by operating the specific button 27 after off-hook detection. □ (Effects) As mentioned above, the present invention improves the automatic dialing system of an automatic dialing device that can automatically dial a pre-stored number. The system is equipped with an off-hook detection means and a notification means for notifying the user of automatic dialing, and by activating the notification means and automatically dialing a pre-stored number after off-hook detection, a person who has made a reservation can This can prevent other people from answering the phone.
