Abstract

PURPOSE:To simplify a telephone call in combining with a PB type telephone set and to transmit a PB (push button) signal to the remote side independently of telephone sytem by using a name display device and an acoustic coupler containing a speaker which sends a PB signal corresponding to a telephone number shown by the signals supplied from a control part to the transmitter of a telephone set. CONSTITUTION:A terminal device main body 1 contains a control part 11 which stores previously the names and their corresponding telephone numbers in an incorporated memory. Then a signal is supplied to read out a telephone number of a desired name by an operation button 6. Thus a name and its telephone number of a group corresponding to said signal are read out of a memory and outputted to a display device 7. While the part 11 outputs the signals showing the telephone number to an acoustic coupler 2. A PB signal transmission part 12 of the coupler 2 converts the signals showing the telephone number supplied from the part 11 into PB signals and outputted to a speaker 13. Thus the dialing is possible even with telephone numbers of the same digits by using an ordinary PB type telephone and a small number of buttons 6.

Description

[Detailed Description of the Invention] Technical Field> This invention, when used in combination with a button-type telephone, allows you to easily dial (to call the other party). The present invention relates to a data transmission terminal with a dial sending function that transmits a push button signal to the other party even in the case of

<Prior Art> There are two types of subscriber telephone lines depending on the type of selection signal: dial impulse type and pushbutton (hereinafter referred to as PB) signal type. With the dial impulse type, after picking up the handset and closing the DC circuit, if you turn around the dial number, the DC circuit will be interrupted by the number corresponding to that number.
The local exchange recognizes this and connects it to the other party's phone. On the other hand, for the PB double signal, when you pick up the handset and press the button after closing the DC circuit, two frequencies corresponding to the number are sent out, which is recognized by the central office exchange and connected to the other party's telephone in the same way. Table 1 below shows the corresponding buttons for the two transmission frequencies.

For example, in Table 1 below, if you press button 1, 6
PB multiplied signals of 97 Hz and 1209 Hz are transmitted.

Table 1 By the way, even with such a PB type main phone, when making a call, you need to press as many buttons as there are telephone numbers. 10
This method requires multiple button operations, is cumbersome, and has the problem of having to search for the telephone number to call from a memo or the like.

<Object of the invention> Therefore, the object of this invention is to combine a PB type main telephone,
To provide a data transmission terminal with a dial sending function capable of making a telephone call with a simple operation, capable of being used as an electronic telephone number memo, and capable of transmitting a PB double signal to the other party regardless of the telephone format.

<Structure of the Invention> In order to achieve the above object, the data transmission terminal with a dial sending function of the present invention stores operation buttons including at least a numeric keypad, some names and corresponding telephone numbers in advance in groups. a control unit that reads and outputs a signal representing the name of one of the groups and its telephone number in accordance with the signal input from the operation button from the memory; and a signal input from the control unit;
A display device that displays at least a name, and an acoustic cover that has a speaker that transmits a button signal corresponding to the telephone number indicated by the signal input from the control unit to the transmitter of the telephone. It is characterized by

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In Fig. 1, 1 is the terminal body, 2 is the PB (not shown)
An acoustic coupler for acoustically coupling to a main telephone transmitter, which are integrally constructed.

As shown in FIG. 2, the front panel of the terminal body 1 is provided with operation buttons 6 consisting of a numeric keypad 3 and function keys 5, and a display 7 for displaying a name and a telephone number.

As shown in FIG. 3, the terminal main body 1 includes a control section 1.
1. The control unit 11 stores names and corresponding telephone numbers in advance in a built-in memory, divided into groups in a dictionary style, and then uses the operation button 6 to read out a telephone number with a desired name. When a signal is input, the name of one of the groups corresponding to the signal and the corresponding telephone number are read from the memory and output to the display 7).

The memory is backed up by a battery and retains its memory unless it is erased or rewritten (1), so that the stored data can be used anytime and anywhere. At the same time, the control section 11 outputs a signal representing the telephone number to the acoustic converter 2.

The acoustic coupler 2 connects the PBB signal sending section 12 and the speaker 1.
3, the PB signal sending section '12 converts the signal representing the telephone number inputted from the control section 11 into a PB signal and outputs it to the speaker 13. The speaker 13 is acoustically coupled to a telephone transmitter (not shown).

In the data transmission terminal with dial sending function configured as described above, if the name of the person to call is, for example, Tanakatarou, using an ordinary PB telephone Il or a PB public telephone, the following (1) to (8) will be used. ) in this order.

(1) First, press the search button 5a of the function key 5 on the front panel.

(2) Press the [eye button] on the numeric keypad 3 on the 7-on front panel.

(3) Tanakata Rō and his telephone number are displayed on the display 7.

(4) If the person's name comes from another evening name, the search continues by repeating the operation in (2) until the desired person's name is found.

(5) At this point, take off the receiver of the PB type telephone (not shown) and check the dial tone.

(6) Acoustically connect the acoustic coupler 2 to the transmitter of the PB telephone.

(7) When the call button 5b of the function key 5 on the front panel is pressed, the PB double signal is input to the speaker 13 and dialed.

(8) After dialing, remove acoustic coupler 2 from the transmitter.

Furthermore, this data transmission terminal with dial sending function allows dialing any number of digits of a telephone number by operating only a small number of operation buttons 6. Furthermore, if you add a redial function, you can call back with just one touch.

This data transmission terminal can also be used as an electronic telephone number memo for display only. In this case, the above (6) and (7)
), (8), the user manually presses the repeat button for that number on the telephone while looking at the display 7.

Another feature of the usage of this data transmission terminal is that it can transmit data using a PB double signal. Therefore, until now it was not possible to send a PB double signal with a dial impulse type telephone, but by using this terminal, a PB double signal can be transmitted by connecting the acoustic coupler 2 to the transmitter. Data transmission using PB double signals is slow, but if you use a PB type telephone, you can transmit data without any auxiliary equipment, so it is convenient for simple data transmission. If the received signal on the receiving side is multiplied by the PB signal, a PB type phone can be used without any auxiliary equipment, and a dial pulse type phone can be used to easily transmit data using this terminal. It can be removed by using a data processing system, teleconverter roll system, etc.

The data transmission terminal of the above embodiment has good operability since the terminal main body 1 and the acoustic coupler 2 are integrated.

In the above embodiment, the terminal main body 1 and the acoustic coupler 2 are integrated, but as shown in FIG. 4, the terminal main body 1 and the acoustic coupler 2 may be connected by a cord, or as shown in FIG. The terminal main body 1 and the acoustic coupler 2 may be connected through a socket as shown in FIG. Separate types as shown in FIGS. 4 and 5 are convenient when used frequently as a simple electronic telephone number memo.

<Effects of the Invention> As is clear from the above explanation, the data transmission terminal with a dialing function of the present invention can be used in combination with a PB telephone to make a call with simple operations, and can also receive an electronic telephone number. It can also be used as a memo, and it can also send a PB double signal to the other party regardless of the telephone format.
