Abstract

PURPOSE:To eliminate the need of a private key by automatically transmitting a dial number stored in a dial memory in relation to a key to a telephone line when the operation key is continuously operated for prescribed time after the telephone line is acquired. CONSTITUTION:When a telephone set is off-hooked and a key dial 9 is operated, CPU 14 controls a dial circuit 8, a dial signal is transmitted to the telephone lines L1 and L2, an opposite party is called and communication becomes possible. On the other hand, the dial number for automatic dial origination and the address are stored in the dial memory 13 by a dial key operation. When a hook is off and the dial key is continuously depressed for prescribed time at the time of automatic origination, the dial number registered in the memory 13 is sequentially read by CPU 14 and the dial circuit 8 is controlled, whereby the number is transmitted to the lines L1 and L2 as the dial signal. Thus the private operation key becomes unnecessary.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dialing system in which a dial number is stored in a memory in advance in association with an operation key, and the stored dial number is read out and transmitted to a telephone line.

0002

[Prior Art] Conventionally, in order to realize an automatic dialing function, that is, an automatic dialing function or a speed dialing function, a telephone is provided with a plurality of dedicated operation keys, and by operating these keys, the user can perform the operation in advance. The dial number registered in memory in association with the key is automatically sent to the telephone line.

0003

[Problems to be Solved by the Invention] Conventional telephones must be equipped with dedicated operation keys when adding an automatic dialing function, which increases the cost of the device and also prevents automatic dialing. This has the disadvantage that the number of key operations required increases, making the automatic dialing operation more complicated.

0004

[Means for Solving the Problems] In order to solve such problems, the dial dialing method according to the present invention provides that when an operation key is continuously operated for a certain period of time after the acquisition of a telephone line, this operation key is The associated dial number is read out from the dial memory and automatic dialing is performed.

[0005]

[Operation] If an operation key such as a dial key is continuously operated for a certain period of time after the telephone line is acquired, the dial number stored in the dial memory in association with this key is automatically sent to the telephone line.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a device to which the automatic dialing system of the present invention is applied. In the figure, 11 and 12 are diodes, 31 to 36 are capacitors, 41 and 42 are hook switches, and 51 and 5
2 is a transistor, 6 is a click detection circuit, 7 is a call circuit, 8 is a dial circuit, 9 is a push button dial, 1
0 is a hold music generation circuit, 11 is an amplifier, 12 is a speaker,
13 is a dial memory for storing dial numbers, 14 is a CPU that controls the entire device, and 15 is a function key. Further, 16 is a 16Hz detection circuit that detects an incoming signal;
17 is a buzzer, 18 is a photocoupler that transmits an incoming signal to the CPU 14, 19 is an LED display unit that displays various displays,
20 is a transmitter, and 21 is a receiver.

When this device, that is, this telephone goes off-hook, the loop of telephone lines L1 and L2 is closed by closing the hook switch 41, and the CPU 14 detects that the hook switch 42 is on, and then presses the push button. When the dial 9 is operated, the CPU 14 detects this and controls the dial circuit 8 to send a dial signal to the telephone lines L1 and L2 to call the other party.If the other party answers, the other party is called. You can make calls between. Further, when a call is received from the other party, the buzzer 17 sounds, and if the user goes off-hook at this time, the loop is closed by closing the hook switch 41, and the incoming call with the other party becomes possible. In addition, when registering a dial number for automatic dialing, first press the dial key "#" in the push button dial 9 to enter the registration mode, and then dial the number corresponding to the operation key for automatic dialing. The user presses the key "1" to determine the storage address of the dial number to be stored in the dial memory 13, and then operates the dial key to store the other party's dial number at a predetermined address. When making an automatic dial call, if you go off-hook and hold down the dial key "1" corresponding to the operation key for a predetermined period of time, for example 3 seconds, the dial memory 1 corresponds to the dial key "1".
The dial numbers registered in 3 are sequentially read out by the CPU 14, and the dial circuit 8 is further controlled to sequentially send them as dial signals to the telephone lines L1 and L2.

Next, FIG. 2 shows the CPU 1 in the above embodiment.
4 is a flowchart illustrating the operation of step 4. The detailed operation of the dial transmission method will be explained based on this flowchart. First, in step 50, initialization processing is executed. Then, in step 51, it is determined whether the outside line has been acquired, that is, whether the hook switch 42 is turned on by going off-hook and closing the loop of telephone lines L1 and L2;
If this is determined to be "N", other processing is executed in step 52, but if it is detected that the hook switch 42 is turned on, it is determined to be "Y", and then in step 53, the dial key is pressed. to judge. Then, if the pressing of the dial key is not detected and it is determined as "N",
Proceeding to step 54, other outside line processing is executed.
Further, if pressing of a dial key is detected, it is then determined in step 55 whether the telephone number associated with the pressed dial key has been registered in the dial memory 13. If the telephone number associated with the pressed dial key is not registered, normal dialing is performed, and the process moves to step 56 where the dial signal corresponding to the pressed dial key is sent to the dial circuit. 8 and sends it to telephone lines L1 and L2.

[0009]Furthermore, if the telephone number associated with the pressed dial key has already been registered, the determination in step 55 is "Y", and in this case, in step 57, a pressing timer is started, and Step 5
At step 8, it is determined that the dial key has been released, that is, the pressed dial key has been released. If the pressed key is released before the pressed timer times out, the call is made by normal dialing, and step 56
, a dial signal corresponding to the pressed dial key is generated from the dial circuit 8, and the telephone line L1, L2 is transmitted.
Send to. In addition, if the release of the pressed dial key is not detected, that is, it is determined as "N" in 58,
In step 59, it is determined whether the timer while being pressed has timed up, and if this is "N", the process returns to step 58, but if the timer while being pressed has timed out while the dial key is being pressed,
In step 60, the dial numbers registered in association with the dial keys are sequentially read out from the dial memory 13, and the dial circuit 8 is controlled to sequentially generate dial signals corresponding to these dial numbers to the telephone lines L1 and L2. Send.

[0010] In this embodiment, the judgment as to whether or not the telephone number associated with the pressed dial key is registered is made immediately after pressing the dial key.
This may be done when the key is released, and the number to be registered is not limited to a telephone number, and various service numbers using PB signals may be registered.

[0011]

As explained above, in the dialing method according to the present invention, when an operation key such as a dial key is continuously operated for a certain period of time after the acquisition of a telephone line, the dialing system is stored in the dial memory in association with this key. The dial number stored in is read out and sent to the telephone line, so
Automatic dialing is possible without providing a dedicated operation key, and the device can be configured at low cost, and the automatic dialing operation is simplified.
