Abstract

PURPOSE:To easily display a letter on a display means through telephone operation by controlling the entire system in such a way that the letter is displaced on the display means with a signal externally input through a telephone line and the like. CONSTITUTION:When the signal acception from a telephone 6 is verified by a signal acception detection part 31, a telephone line 1 and a main device are connected together by a signal input/output switching part 32, and a connection verification signal is transmitted to the telephone 6 by a signal output part 34 through the telephone line 1, while it is waited that the command signal is input to a control means 4. When the command signal is input, when the command signal received by the control means 4 is a letter code, the letter code receiving verification signal which is the same as this letter code is transmitted from the signal output part 34 to the telephone 6, while the letter correspondent to this letter code, is displaced by a display means 5 through the control means 4. A letter and the like can thus be displayed easily from anywhere to the display means.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remotely controlled character display device using a communication line.

2. Description of the Related Art Conventionally, as means for displaying characters on a display board, there have been methods such as writing them on a handwritten message board or writing them on memo paper and posting them in a conspicuous place.

Problems to be Solved by the Invention However, with the above-mentioned conventional character display means, it is necessary to perform the display at a place where the display means is located, in other words, at a place where it is necessary to display. There is a problem in that when the user is in a location, it is not possible to display characters or the like on the display target.

The present invention solves the above-mentioned problems, and provides a remote control that allows characters, etc. to be easily displayed on the display means from anywhere by using a communication line even when the user is located far from the display means. The object is to provide a character display device.

Means for Solving the Problems In order to achieve the above object, the present invention provides the following features:
It is provided with a control means for controlling the entire display so as to display characters on the display means.

Operation With the above configuration, the present invention can instruct a character code via a communication means and display the characters on a display means at a remote location.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the configuration of a remote control character display device according to an embodiment of the present invention, FIG. 2 is an explanatory diagram showing how the device is used, and FIG. 3 is a flow chart showing the operation of the device. .

1 and 2, 1 is a telephone line, 2 is a connection means between the telephone line 1 and this device, and 3 is an input/output signal control means for controlling input/output signals to the connection means 2. A destination detection unit 31 that detects whether there is an incoming call from outside. A signal input section 33 that converts the analog input signal from the telephone line 1 into a digital signal and reads it. A signal output section 34 that converts a digital output signal into an analog signal and sends it to the telephone line 1; It is comprised of a signal input/output switching section 32 that performs the following operations.

Reference numeral 4 denotes a control means using a personal computer or the like, so that display data such as characters is displayed on a display means 5 to be described later by a signal inputted from the outside to the signal input section 33 via the telephone line 1. Controls the functions of the entire device.

The display means 5 is for displaying characters as shown in FIG. 2 determined based on the input signal from the telephone 6 connected to the telephone line 1, and is, for example, a liquid crystal display or a light emitting diode (LED). It consists of a display, etc.

Next, the operation of this apparatus having the above-mentioned components will be explained with reference to FIG.

First, when the incoming call detecting section 31 confirms an incoming call from the telephone 6 (step 91), the signal input/output switching section 32 connects the telephone line 1 and this device (step 92). sends a connection confirmation signal to the telephone 6 via the telephone line 1 (step 93), and waits for an instruction signal to be input to the control means 4.

When the instruction signal is input, the control means 4 checks whether the received instruction signal is an end signal (step 94), and if it is not an end signal, further checks whether the instruction signal is a character code. (Step 95).

Here, if the instruction signal is a character code, a character code reception confirmation signal identical to this character code is sent from the signal output unit 34 to the telephone 6 in order to confirm that the character code has been received (step 96), and after the control means 4 causes the display means 5 to display the character corresponding to this character code (step 9a), the process returns to step 94 described above.

On the other hand, if the instruction signal is not a character code in step 95, it is determined that an input error has occurred and the process returns to step 94 to confirm receipt of the end signal. Also, if there is no instruction signal input,
Step 94 → Step 95 → Step 94 → Step 96 → Step 94 → Until some signal input is made
Repeat the following actions.

Next, when the end signal is received at the Nutep 94,
In order to confirm that the termination signal has been received, a termination reception confirmation signal identical to the termination signal is sent from the signal output section 34 to the telephone 6 (step 98), and the signal input/output switching section 32 switches between the telephone line 1 and the telephone line 1. Disconnect from this device (step 99) and wait for an external call (step 91)
Return to

In the above, for example, if the character code is the JIS Kanji code converted into a decimal number (5-digit number) and the end signal is #, in reality, dialing the number corresponding to that number on the telephone 6 is performed. As a result, a character code and an end signal are sent.

As described above, according to the remote control character display device according to the embodiment of the present invention, the control means is arranged to confirm that the character code has been received and display it on the display means, so that the control means is arranged to display it on the display means after confirming that the character code has been received. Characters can be displayed on a display means at a remote location via the .

In this embodiment, communication between the telephone 6 and the remote control character display device was carried out via the telephone line 1, but for example, a wireless communication line may also be used.
The end signal and both of these signals may be changed to audio, and the reception confirmation signal may be changed to audio.

Effects of the Invention As is clear from the above embodiments, according to the present invention, signals input from the outside to the input/output signal control means via a telephone line etc. control the entire display so as to display characters on the display means. Since the configuration is equipped with a control means, it is possible to instruct the character code via a telephone line etc. and display the characters on the display means. Therefore, even if you are in a place far from the display means, you can easily operate the telephone. It is possible to provide a remote-controlled character display device that easily displays characters on a display means.
