Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic dialing device. especially,
The present invention relates to an automatic dialing device capable of storing telephone numbers including hooking operations.

Conventionally, when an automatic dialing device is used to transfer a call after answering an incoming call on a line with a hooking service, it has been necessary to manually perform the hooking operation using the telephone's hook switch. This locking operation is an operation that opens the line for a certain period of time, but it is not easy to manually open the line for a certain period of time, and if the opening time deviates from the specified period, the line will be disconnected. Transferring lines by manual hooking operation has the drawback of requiring skill.

The present invention eliminates the above-mentioned drawbacks caused by manual picking operations, and is an automatic dialing device that always provides accurate picking operation time, does not disconnect the line during line transfer, and performs correct picking operations. The purpose is to provide

The present invention includes a storage means for storing the telephone numbers of a plurality of subscribers, and a control circuit that reads the telephone number of a subscriber designated by a button operation from the storage means and sends it to a line; and a hooking circuit connected to the control circuit that opens the line for a certain period of time in response to a signal instructing a hooking operation from the control circuit when the hooking button is operated. In the automatic dialing device, the control circuit is configured to, in a storage state in which the subscriber telephone number is stored in the storage means, when the hooking button is pressed, the hooking button operation information is stored together with the subscriber's telephone number to be stored. means for storing in the storage means; and means for sending a signal instructing the hooking operation to the hooking circuit when sending the subscriber telephone number together with the hooking button operation information stored in the storage means. It is characterized by containing.

For lines where the dialing signal is a dial impulse, a hooking circuit is not provided separately, but a circuit common to the dialing circuit is used, and the circuit is opened for a short time for dial impulses, and the circuit is closed for hooking. Preferably, it is configured to remain open for an extended period of time. Further, for a line in which the dial signal is an audio frequency dial signal, a hooking circuit must be provided separately.

Next, an embodiment of the present invention will be described based on the drawings.

The figure is a configuration diagram of an apparatus according to an embodiment of the present invention. In the figure, 1 is an automatic dialing device, 2 is a telephone, and 3 is a line. This line 3 is the automatic dialing device 1
The telephone 2 is controlled to be connected to the telephone 2 and the automatic dialing device 1 via contact pieces A and B of a switch 4 provided therein. A detection circuit 5 is connected between the switch 4 and the telephone 2, and this detection circuit 5 detects when the telephone 2 goes off-hook.

This automatic dialing device 1 is provided with a control circuit 6. This control circuit 6 sends operation commands to each circuit, and the telephone numbers of 16 subscribers, for example, are stored in this control circuit 6. A pushbutton switch group 7 and a hooking button 8 are connected to this control circuit 6. The push button switch group 7 selects a subscriber and provides this selection signal to the control circuit 6. The hooking button 8 is used to give a signal to the control circuit 6 for storing the subscriber's telephone number, including the hooking operation.

The telephone number stored in this control circuit 6 is led to a dialing circuit 9. The dial transmission circuit 9 is a relay circuit that drives a relay in response to a dial signal sent from the control circuit 6 and sends a dial impulse to the line 3 via the switch 4. This dial transmission circuit 9 is connected to the line 3 via the contact piece B of the switch 4. Further, the signal from the line 3 is connected to the amplifier circuit 10 via the contact B of the switch 4 and the dial transmission circuit 9. The output of this amplifier circuit 10 is connected to a speaker 11.

Next, the operation of the device configured as described above will be explained. First, the memory button of the push button switch group 7 in the automatic dialing device 1 is pressed. In response to this, the control circuit 6 enters the storage mode. Next, when the hooking button 8 is pressed, the control circuit 6 enters a mode for a hooking operation that opens the line for a certain period of time (for example, about 0.6 seconds), and when the subscriber selection button of the push button switch group 7 is further pressed, the selected subscriber is selected. A signal for a hooking operation is stored corresponding to each subscriber. Subsequently, by pressing the telephone number using the number buttons of the push button switch group 7, the signal for the hooking operation and the telephone number are stored in that order.

Also, by omitting the operation of the hooking button 8 and pressing the memory button of the push button switch group 7, the subscriber selection button and the numeric button in that order, only the subscriber's telephone number will be stored.

Next, there is an incoming call from line 3, and to explain the transfer operation after responding to this incoming call, the incoming signal from line 3 passes through contact A of switch 4, passes through detection circuit 5, and causes telephone 2 to respond. . After the operator off-hooks and answers, if he presses the subscriber selection button in the push button switch group 7 of the automatic dialing device 1,
The control circuit 6 sends out a telephone number including a hooking operation, which is the stored content corresponding to the subscriber. As a result, the dial transmission circuit 9 releases the line for a time corresponding to the hooking operation, and then transmits a dial impulse. This dial impulse is
It is sent from the dial transmission circuit 9 to the line 3 via the contact B of the switch 4. Also, when only the footing operation is required during a call on Phone 2,
For example, in the case of transfer to a subscriber who is not stored in the control circuit 6, by pressing the hooking button 8, a hooking signal is sent for a certain period of time regardless of how long or short the hooking button 8 is pressed. The control circuit 6 operates to send out the following.

Note that although the above example describes a system in which dial signals are sent by dial impulses, the same applies to systems that use audio frequency dial signals, and in this case, a circuit for the hooking operation may be provided separately from the dial transmission circuit.

As explained above, according to the present invention, by providing a footing button for the footing operation and configuring the telephone number including the footing operation to be memorized, it is possible to always obtain an accurate footing operation time, and to At the time of transfer, the hooking operation is automatically performed, which has the excellent effect of omitting manual hooking.
