Abstract

PURPOSE:To call a destination at a designated date and time entered in advance even when a subscriber forgets the designated date and time. CONSTITUTION:When a call reaches, an automatic reply circuit 14 replies the call automatically and a PB signal reception circuit 10 or a DP signal reception circuit 11 receives and stores an automatic dialing date and time and an opposite number in succession to a predetermined automatic dialing function selection signal. A time comparator circuit 12 extracts a current time from a clock circuit 13 and compares it with an automatic dialing date and time stored in the PB signal reception circuit 10 or the DP signal reception circuit 11 and starts an automatic dialing circuit 15 and a call circuit 16 when they are coincident. The started automatic dialing circuit 15 reads the opposite number stored in the PB signal reception circuit 10 or the DP signal reception circuit 11 to make automatic dialing and the call circuit 16 rings a call tone to call a subscriber.

0002

2. Description of the Related Art Conventionally, this type of answering machine has a structure in which the desired date and time for automatic dialing and the telephone number of the other party are set using a push button.

0003

[Problems to be Solved by the Invention] The above-mentioned conventional answering machine is configured to use a push button to automatically set the date and time of the call and the number of the other party. When you hear a message stored in your phone, you cannot set the date and time you want to automatically call and the number you want to call on the spot, so you have to keep in mind that you will be contacted at the specified date and time, and if the date and time are There is a problem that the longer it is in the future, the more likely it is that people will forget, which is troublesome.

a paging circuit that calls a subscriber according to an instruction from the time comparison circuit, and the DP signal receiving circuit has an interface circuit that interfaces with a telephone line;
a filter circuit that cuts extra frequencies due to noise other than AC noise due to the signal; a voltage level detection circuit that distinguishes between noise having the same period as the DP signal and AC noise due to the DP signal; and a counter that counts the DP signal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, the present embodiment includes a PB signal receiving circuit 10 that receives and stores the automatic calling date and time and the called party's number sent by the PB signal, and a PB signal receiving circuit 10 that receives and stores the automatic calling date and time and the called party's number sent by the DP signal. a DP signal receiving circuit 11 that receives and stores the time signal; a clock circuit 13 that generates a time signal;
A time comparison circuit 12 that compares the time stored in the signal reception circuit 10 or the DP signal reception circuit 11 with the current time; an automatic response circuit 14 that automatically answers an incoming call; An automatic calling circuit 15 that makes a call to a destination number stored in the PB signal receiving circuit 10 or DP signal receiving circuit 11 according to instructions, and a time comparison circuit 12
A calling circuit 16 that calls the subscriber according to an instruction from the subscriber.

Next, the operation of this embodiment will be explained using FIG. 1.

First, when a subscriber calls the answering machine of this embodiment from his/her home, the automatic answering circuit 14 automatically answers the call. Next, when the subscriber sends a predetermined automatic call function selection signal, followed by the automatic call date and time and the other party's number (by pressing the PB button or turning the dial on the telephone at his/her destination), the PB signal receiving circuit 10 or The DP signal receiving circuit 11 receives and stores these PB signals or DP signals.

The time comparison circuit 12 extracts the current time from the clock circuit 13, compares it with the automatic transmission date and time stored in the PB signal receiving circuit 10 or the DP signal receiving circuit 11, and determines whether the current time is stored as the current time. If the automatic transmission date and time match, the automatic transmission circuit 15 and the calling circuit 16 are activated.

The activated automatic calling circuit 15 extracts the telephone number of the other party stored in the PB signal receiving circuit 10 or the DP signal receiving circuit 11, performs a calling operation based on the number information, and calls the other party. On the other hand, the paging circuit 16 calls the subscriber based on instructions from the time comparison circuit 12. When the subscriber picks up the handset, the call operation is no different from conventional calling operations; if the other party does not answer, a ring tone is heard, and if the other party answers, the call can continue.

FIG. 2 is a block diagram showing an example of the DP signal receiving circuit shown in FIG.

Next, the DP signal receiving circuit will be explained using FIG. 2.

In FIG. 2, the DP signal receiving circuit 11 in this embodiment includes an interface circuit 20 for connecting to a telephone line, and a filter circuit 21 for cutting extra frequencies caused by noise other than AC noise caused by the DP signal.
, a voltage level detection circuit 22 for distinguishing between noise having the same period as the DP signal and AC noise due to the DP signal, a counting circuit 23 for counting the DP signal, and a storage circuit 24 for storing the counted DP signal. It is composed of

Next, the operation of the DP signal receiving circuit in this embodiment will be explained using FIG.

AC noise caused by the DP signal input to the interface circuit 20 via the telephone line is filtered out by the filter circuit 21.
Detects only frequencies of 10 pps or 20 pps to cut noise. However, since there is no guarantee that noise with the same frequency as the DP signal will not occur, the voltage level detection circuit 22 at the next stage takes into account the voltage of the AC noise caused by the DP signal in order to distinguish between the noise and the AC noise caused by the DP signal. A certain voltage width is set, and signals with other voltages are considered noise. By distinguishing between noise and alternating current noise caused by the DP signal in two stages, frequency and voltage, it is possible to detect the DP signal with high accuracy. Thereafter, if the detected DP signals are counted by the counting circuit 23 and stored in the storage circuit 24, it is possible to receive and store the DP signals dialed from the place of the office.

[0017]

[Effects of the Invention] As explained above, the present invention allows a subscriber to set the automatic dialing date value and the telephone number of the other party from the telephone at the office, regardless of the type of telephone at the office (PB type, DP type). By making this possible, the subscriber is automatically called and the other party is also called when the specified date and time is reached, so even if the subscriber forgets the specified date and time, he or she can still talk to the other party at the specified date and time.
