Abstract

PURPOSE:To facilitate the easy change of voice data by rewriting of a command sentence by providing a means which can judge the command as a voice generating command in the command sentence. CONSTITUTION:A control section 4 is constituted of a microprocessor (CPU), a memory (RAM, ROM), an interface (I/F), etc. This control section judges the prescribed command as a voice generating command and outputs the corre sponding voice data to a voice generating section 3. Since the program of an interpreter type to successively interpret and execute the command sentence is provided in such a manner, the voice data can be described in the command sentence. Then, the change of the voice data is executed extremely simply by rewriting the command sentence without describing the same into a system program for controlling the light emitting display device 1 and the voice genera tor 3. The alteration of the voice data by a user is allowed in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a light emitting display that displays characters, etc. on a display screen on which light emitting elements are arranged.

[Prior art and problems to be solved by the invention] Generally,
Among these types of light-emitting display devices, there are some that are configured to notify the display contents by sound, such as departure and arrival time display devices for trains and buses.

However, in the past, display data and audio data were written in a system program for controlling the display and audio generator, so if the above data needed to be changed, the system program had to be rewritten. The reality is that it is virtually impossible for users to change data.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a light-emitting display capable of eliminating these drawbacks, and which displays characters. In a light-emitting display comprising a control unit that controls display of a light-emitting display unit and controls sound generation of a sound generation unit that generates sound, the control unit stores a command sentence written by an external input device. A storage means and a sequential interpretation execution means for sequentially interpreting and executing the stored command sentences are provided, and the sequential interpretation execution means determines that a predetermined command is a voice generation command and transmits corresponding voice data. The present invention is characterized in that it includes a voice command determining means for outputting to the voice generating section.

According to the present invention, with this configuration, audio data can be changed extremely easily.

[Embodiment] Next, an embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a light emitting display, and the light emitting display 1
The display section 2, which is formed by arranging display elements such as light emitting diodes in a matrix, displays display data such as characters, symbols, figures, etc. output from the control section 4, which will be described later, in a static display,
The light emitting display is performed in various display patterns such as a flowing display, a blinking display, and an inverted display, but the basic configurations of these are the same as conventional ones.

Reference numeral 3 denotes a sound generation device, and the sound generation device 3 is configured to generate sound based on the sound data output by the control unit 4, but this device does not store basic sound data. In order to achieve this, the system is equipped with an appropriate storage means such as a tape recorder, an IC memory, a floppy disk, a hard disk, etc., and as an audio generation source, an appropriate device such as a PCM recording device, a regular speech synthesizer (synthesizer), etc. is provided.

The control unit 4 is composed of a microprocessor (CPU), memory (RAM-ROM), interface (I/F), etc., but it is not possible to use an external input device (word processor, personal computer, etc.). Based on the written command sentences, data is output to the light emitting display 1 and the sound generating device 3, respectively. That is, the control unit 4 includes an interpreter-type program that sequentially interprets and executes command statements transferred from an external input device to a memory (RAM) via a communication cable.

Here, the control procedure of the above program will be explained based on FIG. 2. When this control starts, first the variable n is set to 1.
After setting, the nth line of the command statement is read, but in the line data, the data written in parentheses at the beginning of the line is recognized as time specification data, and the data written in parentheses following this is recognized as a command. The data that is subsequently written is recognized as display data or audio data. Next, it is determined whether or not the specified time has arrived, and if it is before the specified time, it will be in a standby state until the specified time, but if it is determined that it is the specified time, it will also issue a command (V). Determine whether it is written or not. If the judgment is YES, the data written in the line is output to the sound generator 3, while if the judgment is NO, the data is output to the light emitting display 1. ing. After outputting the data, the variable n is set to n+1 in order to read the next line, and the above control is repeated.

In an embodiment of the invention constructed as described.

The light emitting display 1 performs display operation based on a command sentence written in a word processor or the like and then transferred via a communication cable.
If this is written, the data written thereafter will be recognized as audio data and output to the audio generator 3. In other words, if it is necessary to change the audio data, the command statement can be rewritten, and the user can therefore rewrite the audio data.

As described above, the present invention has not only a light emitting display function but also a sound generation function, and since it has an interpreter type program that sequentially interprets and executes command sentences, it is possible to incorporate sound data into command sentences. can be described. Therefore, the voice data can be changed extremely easily by rewriting the command statement without writing it in the system program for controlling the light emitting display 1 or the voice generator 3. Data can be changed.

It goes without saying that the present invention is not limited to the above-mentioned embodiment, and, for example, the grammar of the command sentence is not limited to that of the above-mentioned embodiment.

[Operations and Effects] In short, the present invention is configured as described above, and although it is equipped with a light-emitting display section that displays characters and a sound generation section that generates sounds, it does not have to be written in a command sentence. Since the apparatus is equipped with a means for determining that a predetermined command is a voice generation command, voice data can be written in a command sentence.

Therefore, the audio data can be changed extremely easily by rewriting the command statement without writing it in the system program for controlling the light-emitting display section or the audio generating section. Changes can be made.
