Abstract

PURPOSE:To simplify transmission operation by using a character string-dial number conversion table so as to convert a character string inputted from a touch screen into a dial number and sending the number as a selection signal. CONSTITUTION:A character designating a called station is inputted from a touch screen 2 by hand-writing. A pattern recognition circuit 20 recognizes its character and converts it into a character code, and a control circuit 6 receives the character code and stores it. When a series of input of character string is finished, the control circuit 6 reads a display pattern to display the character string from a word memory circuit 11 and displays it on a display circuit 9. In turning on a dial pulse sending switch 12, the control circuit 6 reads a dial number corresponding to the character string from a character dial memory circuit 10 and displays it to the display circuit 9 together with the character string and outputs the dial number to a selection signal sending circuit 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character dial telephone using a touch screen.

[Conventional technology]

Initiating a telephone conversation typically involves operating a dial to send a selection signal to the telephone line.

With rotary dialing, you simply dial the number of the called station, but with push-button dialing,
In addition, you can utilize the speed dial function.

Speed dialing allows dialing quickly and reliably without knowing the dial number of the called station.

However, speed dialing is a combination of symbols and numbers, and is not a code that directly indicates the called station. Therefore, it is necessary to refer to the speed dial list before dialing. In order to solve this problem, one has to actually type in the name of the called station (the problem that the invention aims to solve). - It was connected to a personal computer and operated to convert character information entered from the keyboard into a dial number.

Therefore, since the number of external devices other than the telephone increases, there are disadvantages in that the cost increases and the floor area used, that is, the installation space becomes large.

The present invention has been made with attention to the above points, and an object of the present invention is to provide a telephone that uses a touch screen and has a character dialing function added thereto.

[Means for solving problems]

The character dial telephone of the present invention includes a touch screen that detects pressing force and outputs a detection signal corresponding to the position of the pressing force on the screen, and recognizes characters drawn and input by hand on the touch screen. a pattern recognition circuit, a display circuit that displays the characters thus recognized, a character dial memory circuit that stores the correspondence between character strings and dial numbers;
A control circuit converts the character string input from the touch screen into a dial number based on the correspondence relationship stored in the character dial memory circuit, and sends this as a selection signal to the telephone line. It is something to do.

[Effect]

This phone inputs character strings from the touch screen. Therefore, a large keyboard or the like is not required.

Further, within the telephone, this character string is recognized and converted into a dial number using a character string-to-dial number conversion table prepared in advance. The number thus obtained is sent as a selection signal to the dial.

FIG. 1 is a block diagram showing an embodiment of a character dial telephone according to the present invention.

This telephone 1 includes a touch screen 2, a pattern recognition circuit 20 that processes input signals from the touch screen 2, a control circuit 6 that controls the operation of the entire telephone, and a display circuit 9 and a word memory circuit. 11, a character dial memory circuit 10, a selection signal sending circuit 7, and a network 8 are provided.

The pattern recognition circuit 20 includes a sensor circuit 3 and an encoding circuit 4.
and a data identification circuit 5.

As is well known, pattern recognition circuits are
A sensor circuit 3 detects a pattern input by hand using a touch screen 2, an encoding circuit 4 encodes the pattern, and a data identification circuit 5 operates to identify the content of the character to obtain a character code. It is a circuit. This character code is later processed by the control circuit 6.

On the other hand, the word memory circuit 11 and the character dial memory circuit 10 are read-only memory elements and random
Consists of access memory elements, etc.

This word memory circuit 11 is a circuit that operates to receive a character code from the control circuit 6 and output a pattern for displaying the corresponding character. The character dial memory circuit 10 is a circuit that registers a table showing the correspondence between a character string corresponding to the name or initial of a called station and a dial number of the called station. The character dial memory circuit 10 is a circuit that operates to accept a character code corresponding to a character string and output a corresponding dial number.

The display circuit 9 consists of a display element such as a liquid crystal and a circuit for driving the display element, and according to instructions from the control circuit 6, the word memory circuit 11
It is used to display patterns such as character strings output from.

The control circuit 6 is a circuit that processes operations for telephone calls, such as processing character strings input from a touch screen and controlling the operation of a selection signal circuit, and includes, for example, a microprocessor and an interface with a memory that stores its operation program. Consists of etc.

Connected to the control circuit 6 are a dial pulse sending switch 12 for instructing the start of a dial operation, and a character dial registration switch 13 for instructing an operation to newly register a character string and dial number.

The selection signal sending circuit 7 is a circuit that outputs a selection signal to the network 8 in accordance with the dial number output from the control circuit 6.

The character dial telephone of the present invention having the above configuration operates as follows.

First, the caller turns off the hook switch of the telephone and inputs a character designating the called station by hand from the touch screen 2. The sensor circuit 3 operates when the hook switch is off-hook, and the pattern recognition circuit 2
0 recognizes the character and converts it into a character code. The control circuit 6 receives and holds this character code. When this operation is repeated and the input of a series of character strings is completed, the control circuit 6 reads out a display pattern for displaying the character string from the word memory circuit 11 and displays it on the display circuit 9.

If the content input from the touch screen and the content displayed on the display circuit 9 match, the caller turns on the dial pulse sending switch 12.

Taking this as a signal, the control circuit 6 reads out the dial number corresponding to this character string from the character dial memory circuit 10. Then, the dial number is displayed on the display circuit 9 along with the character string, and the dial number is outputted to the selection signal sending circuit 7.

The selection signal sending circuit 7 receives this and sends out a predetermined selection signal through the network 8. In this way, the called station is called.

As described above, a specific called station can be called by inputting a handwritten character string from the touch screen.

On the other hand, in order to carry out the above operations in this telephone, it is necessary that the correspondence between the character string and the dialed number of the called station be registered in the character dial memory circuit.

Therefore, the procedure of the registration operation will be explained.

In this case, first, the character dial registration switch 13 is turned on. This causes the control circuit 6 to control the touch screen 2.
It enters a state where it is waiting for data to be input.

From the touch screen 2, a character string and a corresponding dial number are successively input.

This is input to the control circuit 6 through the pattern recognition circuit 20. The contents are then added to the table of the character dial memory circuit 10. When this registration work is completed, the character dial registration switch 13 is turned off and the registration work is completed.
