2. Description of the Related Art When making a telephone call to a desired party, it is generally necessary to dial a national number (usually 9 digits). Since pressing a nine-digit number in this way often results in incorrect presses and takes time, speed dialing services have been widely used in PB telephones.

[0003] This is a system in which the phone numbers of several people you call relatively frequently are registered in advance as two-digit numbers. First, after pressing the button marked with an *, By pressing a digit, it is converted to the corresponding phone number of the other party and the call is made.

0004

[Problems to be Solved by the Invention] However, for example, in cases where the destination of the call is fixed and the frequency of calls is extremely high, there has been a demand for even more advanced shortening.

[0005] The present invention aims to realize an automatic dialing device that makes use of the speed dialing service conventionally used in PB telephones and allows dialing to a pre-registered party by simply lifting the handset. There is.

[0006]

[Means for Solving the Problems] FIG. 1 is a basic configuration diagram for explaining the principle of the present invention. In Figure 1, 1
is a call detection means, and this call detection means 1 is connected to a terminal T.
It is connected to a PB telephone (not shown) via the PB telephone, and detects that the connected PB telephone goes off-hook, that is, the loop is closed. Reference numeral 2 denotes a scanner for monitoring call detection by the call detection means 1, and reference numeral 3 denotes a storage means for storing an abbreviated two-digit number corresponding to the telephone number of the party to be automatically dialed.

Further, reference numeral 4 denotes a control means, which periodically accesses the scanner 2, recognizes that the call detection means 1 has detected a call, reads out the memory contents of the storage means 3, and reads the stored contents of the storage means 3. It outputs a control signal corresponding to the stored contents to the PB oscillator driving means 5.

The PB oscillator driving means 5 receives a control signal from the control means 4 and drives the PB oscillator 6. That is, the control means 4 decodes the content read from the storage means 3, receives the decoded signal, and P
The B oscillator 6 is driven to output the PB signal which is the abbreviated code (*00) from the PB oscillator 6.

[0009]

[Operation] The operation of this configuration will be explained next. In this case, the telephone number of the other party to be automatically dialed will be explained as "012-345-6789". First, this number is abbreviated registered to the telephone office from a PB telephone separate from this device using the procedure of conventional abbreviated dialing services.
0".

[0010] As a result, "*00" is encoded and written into the storage means 3. When the PB telephone connected to this is used to make a call to the party to whom automatic dialing is desired, when the handset is lifted up, the call detection means 1
When off-hook is detected, the control means 4 reads out the contents of the storage means 3. In this case, since the code "*00" is written in the storage means, the code signal is read out and drives the PB oscillator 6.

[0011] In this way, by registering the phone number of the person you want to connect to by automatic dialing using the speed dial service procedure of a normal PB telephone, you can then connect to that person by simply lifting the handset. It is something that is done alone.

0012

[Embodiment] Next, an embodiment of the present invention will be described with reference to FIG. In FIG. 2, 11 is a call detection unit, and 12 is a scanner, which are exactly the same as the call detection means 1 and scanner 2 shown in FIG. It is designed to be connected to a PB telephone (not shown) via a terminal T, as shown in FIG.

Further, 13 is a storage device, for example, RO
M (read only memory) is used, and the telephone number of the other party to be automatically dialed is registered in advance. If "*00" is used as the speed dial code, "*" is entered at address 1 of the storage device 13 and address 2 is
"0" is registered in advance for the address, "0" for the third address, and so on.

Reference numeral 14 denotes a microprocessor that operates as a control means, which recognizes whether or not the call detection unit 11 has detected a call by periodically accessing the scanner 12, and detects the call. When recognized, the contents of the storage device 13 are read out, the contents are decoded, and the PB oscillator drive device 15 is operated.

The PB oscillator drive device 15 includes a signal distributor (usually referred to as SD) 151 that functions as a relay driver, and a relay R.
H0, RH1, RH2, RL0, RL1, R
L2, RL3 and their contacts SH0, SH1,
It is composed of SH2, SL0, SL1, SL2, and SL3.

[0016] The signal distributor 151 (
(hereinafter abbreviated as SD151) is the relay driver DH0
, DH1 , DH2 , DL0 , DL1 , DL2
, DL3 and these relay drivers DH0 to DH
2, DL0 to DL3 are connected to the microprocessor 14
and a relay driver selection section 152 that is selected and driven by a control signal.

Further, 16 is a PB oscillator, and when any one set of relay contacts SH0 to SH2 and SL0 to SL3 is closed, a loop is formed and a signal with a corresponding number is output as a PB signal. It is now possible to do so.

The operation of this PB oscillator 16 will be explained with reference to FIG. Figure 3 shows the numeric keypad section of a commonly used PB telephone.
It consists of pushbuttons numbered ``9'' and pushbuttons numbered ``*'', ``#'', etc. There is a contact point (not shown) under each pushbutton. For example, when the "1" pushbutton is pressed, a loop of H0 and L0 is formed, and "
When the push button 2 is pressed, a loop of H1 and L0 is formed.
A loop of any combination of H2 and L0 to L3 is formed.

In such a configuration, if we consider the operation in terms of the on/off of the relay contacts shown in FIG. 2, for example, pressing the "1" push button means that the relay contacts On, and the push button "2" being pressed means that relay contacts SH1 and SL
1 means it is on. In other words, when the relay contacts SH0 and SL0 are on, the loop of H0 and L0 is closed and the PB signal corresponding to "1" is output, and when the relay contacts SH1 and SL1 are on, the loop of H1 and L1 is closed. is closed, and the PB signal corresponding to "2" is output.

Accordingly, when each of the relay contacts SH0 to SH2 and SL0 to SL2 is closed by the operation of the SD151, the PB signal corresponding to that number is output.

Next, the operation of the embodiment configured as described above will be explained. In this embodiment as well, the phone number of the person you want to automatically dial is 012-345-6.
789”. First, this telephone number is abbreviated to "*00" and registered using the speed dial service procedure, and the code is stored in the storage device 13. In this case, "*" is stored at address 1, "0" at address 2, "0" at address 3, and so on.

[0022] In this state, when making a call to the other party at "012-345-6789" from the PB telephone connected to this device, when the handset is lifted, the call detection unit 11 first detects the hook-off. do.

The microprocessor 14 periodically accesses the scanner 12, and when the call detection section 11 detects a call, it recognizes this and starts reading out the contents of the storage device 13.

Then, the data is sequentially read from the storage device 13 starting from address 0, the contents are decoded, and the signal distributor SD is driven. That is, a control signal corresponding to "*00" is sent to the SD 151. As a result, SD15
1 first drives relay drivers DH1 and DL3 to operate relays RH1 and RL3. As a result, the contacts SH1 and SL3 are closed, the loop of H1 and L3 of the PB oscillator 16 is closed, and the PB signal corresponding to "*" is output. Next, relay drivers DH0 and DH0 are driven, and relay RH0
and RL0 are activated, their contacts SH0 and SL0 are closed, and the loop of H0 and L0 of the PB oscillator 16 is closed, and a PB signal corresponding to "0" is output.

In this way, predetermined relays are activated one after another, a loop corresponding to the PB oscillator 16 is formed, and a predetermined PB signal is output, eventually becoming "*00".
The PB signal with the number will be output. "*00"
The exchange that received the
45-6789" and transmits to the other station.

[0026] Therefore, if you register the telephone number of the person you want to automatically dial using a speed dial service procedure from a normal PB telephone, you can connect to that party by simply lifting the handset of the PB telephone. become.

[0027] In the above embodiment, the case where the speed dial number to be registered is fixed at one location, ``*00'', has been explained, but the invention is not limited to this. There are two locations, and during the day,
*00" and "*01" at night, and by using a timer or the like to change the number according to the time and read out the registered number, it is possible to automatically dial two locations. Furthermore, by registering a plurality of abbreviated numbers from "*00" to "*19" and switching between them, it is possible to automatically dial a plurality of locations.

[0028]

[Effects of the Invention] According to the present invention, the commonly used P
By connecting your B phone and registering the shortened phone number of the other party, you can connect to that party using automatic dialing. This greatly reduces the hassle of making calls and greatly improves convenience, and because it utilizes the speed dial service, a function that exchanges have traditionally had, it does not require significant addition of hardware. Therefore, it is possible to realize an automatic dialing device that is excellent in terms of cost.
