Abstract

PURPOSE:To eliminate the need for dialing in calling other telephone set in the same group by adopting the constitution that another telephone number stored in the same group is sent automatically in the case of busy state. CONSTITUTION:Plural telephone numbers are grouped whether or not they belong to the same department and the grouped telephone numbers are stored in advance in a storage means 8. In depressing one button in a group designation switch group 7a, a control means 11 reads a telephone number stored in the storage means 8 and drives a dial pulse sending means 4 to send a dial signal. In this case, if the opposite party is busy, a line closing means 2 is controlled to open the line once. The other telephone number in the same group stored in the storage means 8 is read and sent to the line automatically by using the dial pulse sending means 4.

Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD The present invention relates to a telephone.

Conventional technology Traditionally, multiple telephone numbers are stored, one of the stored telephone numbers is read out by a simple key operation, and a dial signal is sent to the line in response. There were telephones with automatic dialing devices. Also,
These devices generally have an auto-redial function that temporarily opens the line if the other party is busy, then closes the line again, and dials the same number again. Ta.

Problems that the invention aims to solve By the way, if there are multiple telephones in the same department, such as an office, you can call whichever phone in that department you want in order to convey your business to the other party. However, with conventional telephones such as those mentioned above, only one number can be dialed at a time with one operation, so if the other party's phone happens to be busy, the caller can dial only one number at a time. Cut the
If you called a different number again, you were not allowed to answer the call.Furthermore, if the call was busy again, you had to call again and answer the call.Currently,
The reality is that valuable work time is wasted in this way, and improvements are strongly desired.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and it stores multiple telephone numbers in a storage area, and if the telephone of the first telephone number to call is busy, the line is released once, and the same To provide an easy-to-use telephone by automatically sending a dial signal corresponding to another telephone number stored in a group into a telephone line.

Means for Solving the Problems In order to achieve this object, the telephone of the present invention includes a telephone number storage means for storing a plurality of telephone numbers divided into a plurality of groups, and a line closing means for opening and closing telephone lines. dial signal transmitting means for transmitting a dialing signal corresponding to the telephone number after the telephone line is closed by the line closing means; a busy tone detecting means for detecting a busy tone sent from the telephone line; and a busy tone detecting means for detecting a busy tone sent from the telephone line; and a line closing means which once releases the telephone line in response to the output of the busy tone detecting means, and then disconnects the telephone line again. The circuit is closed and a dialing signal corresponding to a telephone number stored in the telephone number storage means that is within the same group as the previously transmitted telephone number but different from the previously transmitted telephone number is transmitted to the telephone line. The configuration includes a control means for performing control.

Effect With the above configuration, for example, if the telephone numbers of multiple telephones in the same department are stored in the telephone number storage means as the same group, when one telephone is busy, other telephones in the same group The call will be automatically called, so you don't have to manually dial another phone.

The operation of the telephone of this embodiment configured as described above will be explained below.

First, let's talk about the operation in phone number storage mode.
This will be explained with reference to the figures and FIG.

First, one button of the group designation switch group 7a is pressed to designate a group in which a plurality of telephone numbers are to be stored (step a). Thereafter, the first telephone number is input by pressing the dial button 6 (step b). This manually inputted first telephone number is temporarily stored in the temporary storage means 11a in the control means 11. When the input of the first telephone number is completed, the process proceeds from step C to step d, where the operator inputs the first telephone number and the second telephone number.
Press separator button 5 to specify the delimiter for the th telephone number. This delimiter is stored consecutively after the last digit of the first telephone number input in the temporary storage means 11a in the control means. Thereafter, the second telephone number is input in the same manner as when the first telephone number was memorized (step b). Then the second phone number is control means 1
It will be stored next to the delimiter stored in the temporary storage means 11a in 1. When inputting the third and subsequent telephone numbers, the user inputs the telephone numbers manually after entering a break using the separator button 5 in the same manner. When all phone numbers to be memorized are completed, memorize button 7b
Press (step e). As a result, the control means 11 first outputs a signal specifying the address corresponding to the specified group to the storage means 8, and then records the contents stored in the temporary storage means 11a in the control means 11 and the write control signal. It is output to the storage means (RAM) 8, and the telephone number is written therein.

Next, the dial transmission mode will be explained with reference to FIGS. 1 and 3.

First, in step f, it is determined that the telephone line 1 is off-hook, and the telephone line 1 is closed by the line closing means 2 (step g).
) Dial dialing is now possible. Although it is of course possible to make a normal call by operating the dial button 6 in this state, the explanation thereof will be omitted here, and the case of making a call using the telephone number stored in the storage means 8 mentioned above will be explained. In that case, first, the telephone light group is selected by pressing one button in the group designating switch group 7a (step h). Then, the control means 11
outputs the address signal and read control signal corresponding to the pressed group designation switch to the storage means 8. As a result, the storage means 8 outputs the stored contents, and the output contents are temporarily stored in the temporary storage means 11a in the control means 11 and then inputted to the dial sending means 4 as dial data. Here, dial pulse or DTMF (D
UAL TONE MULTIFREQUENCY
) is converted into a signal and sent to the telephone line 1. The dials sent out here are sent out until the control means 11 finds the aforesaid delimiter.

By doing so, the first telephone number is sent out in step i. After a few seconds, the line is connected to the other party, and a ringback tone (ringing tone) is returned (then no busy tone is detected, so the process advances from step j to step 0, and in step 0, the ringback tone is returned. The tone detection means 13 detects the tone, and the process advances to step p, where the transmitting/receiving circuit 3 and a handset (not shown) or a microphone/speaker are ready for a call.Furthermore, if the other party is busy, a busy tone is output from the telephone line 1. is returned, and in step j, the busy tone detection means 1o detects this and outputs the detection signal to the control means 11. When the control means 11 receives the detection signal, it closes the line. The telephone line 1 is temporarily opened by controlling the means 2 (step k), and the timer means 12 is activated.

As a result, the timer means 12 starts counting and outputs an end signal to the control means 11 after 1.6 seconds. During this time, the control means 11 determines whether there is a second telephone number in the same group (step m), and if there is a second telephone number, it controls the line closing means 2 in response to the termination signal to make a telephone call. The line 1 is closed again in step n), and the control means 11 outputs the second telephone number in step i. The second phone number is stored after the first phone number from the next digit of the first separator until the second separator is detected, or from the phone number stored in that group. If there are two numbers, it is up to the last digit of the second telephone number. After sending the second telephone number, the control means 11 again monitors the busy tone. If the other party responds in this state, the busy tone will not be detected, and the process will proceed to step 01, step p.

Further, if the second telephone is also busy, proceed to step 1, step 11, and step m above.

Further, if all telephone numbers are busy, the process advances from step m to step f, and the process returns to a standby state.

Effects of the Invention As described above, the present invention provides a telephone number storage means for storing a plurality of telephone numbers divided into a plurality of groups, a line closing means for opening and closing a telephone line, and a telephone number storage means for storing a plurality of telephone numbers in a plurality of groups; dialing signal sending means for sending a dialing signal corresponding to the telephone number after the closing means has closed; and dialing signal sending means for sending a dialing signal corresponding to the telephone number; and a busy tone sent from the telephone line when the other party is busy after sending the dialing signal; a busy tone detecting means for detecting a busy tone, and in response to the output of the busy tone detecting means, the line closing means once opens the telephone line and then closes the telephone line again and stores it in the telephone number storage means. The control means controls to send to the telephone line a dial signal corresponding to a telephone number that is within the same group as the previously transmitted telephone number and is different from the previously transmitted telephone number. Group phone numbers and memorize them.
If the first phone number you dial is busy, you can open the line and memorize the next number to dial, which saves you the trouble of fixing the call. As a result, no time is wasted, and the practical effects are great.
