It is a control block diagram. As shown in FIG. 1, the present invention is a device for transmitting a remote control signal to a karaoke accompaniment machine, which comprises a touch screen 13, a stylus pen 10, a memory 15, a CPU 14, and an infrared transmitter 1. The touch screen 13 is recognized as a search condition selection unit 8 for setting search conditions such as a song name, a singer name, a start and a new song of a song that the user wants to find, and a character input window 7 for inputting a character to be searched. The input contents display section 6 for outputting the input characters, the search button 11 for performing a search for all the characters including the input word, and the search result display for outputting the search results such as a serial number, a song name, and a singer name It comprises a unit 9 and an execution button 5 for inputting an execution command such as selection, reservation, or cancellation of the searched music. The character input stylus pen 10 inputs characters on the touch screen 13, and the memory 15 stores song data by keys such as song title, singer name, start and new song. The CPU 14 searches the song data stored in the memory 15 for characters input by the input of the search button 11 in units of syllables and phonemes, and displays a search result on the search result display unit 9. And a character recognition program for recognizing characters recorded by the stylus pen 10 in the character input window 7. The infrared transmitter 1 transmits a remote control signal for reproducing the music searched by the CPU 14 to the karaoke accompaniment machine. The touch screen 13 further includes a backlight so that a user can input and select a desired song in a dark room without additional illumination. In addition, the present invention further includes a function key 12 for setting a power, a reset, and a function mainly used. Next, the operation of the present invention will be described. First, the user sets search conditions such as a song name, a singer name, a start and a new song of a song to be searched for by using the search condition selection unit 8 of the touch screen 13. Thereafter, a character to be searched is input to the character input window 7 with the stylus pen 10, and the recognized character is output to the input content display unit 6. At the same time, the search result display unit 9 displays a serial number, a song name, and a singer name. Output search results such as In such a process, the CPU 14 recognizes the character recorded by the stylus pen 10 in the character input window 7 by the character recognition program, and inputs the character input by the input of the search button 11 through the search engine. Then, the music data stored in the memory 15 is searched for each syllable and phoneme, and the search result is displayed on the search result display section 9. At this time, the memory 15 stores in advance music data using keys such as a music title, a singer's name, a start and a new music. Thereafter, when the desired music is displayed on the search result display section 9, the user selects the displayed music name with the character input stylus pen 10. Then, the CPU 14 recognizes this and sends a remote control signal for reproducing the searched music to the karaoke accompaniment machine via the infrared transmitter 1. At this time, when the execution button 5 is selected, the execution instruction to be sent can be selectively input as music selection, reservation, cancellation, and the like. On the other hand, if the desired song is not found even when all the words to be input are entered, the search button 11 is pressed, and a search is performed for all the characters including the input word. The touch screen 13 is provided with a backlight, so that a desired music can be input and selected without additional lighting even in a dark room. In addition, the present invention further includes a function key 12 for setting a power supply, a reset and a function mainly used, thereby making music selection more convenient. The present invention is not limited to the embodiment described above. Anyone having ordinary knowledge in the art to which the present invention pertains can make various modifications without departing from the scope of the present invention as claimed in the appended claims, as well as any such modifications. Within the scope of the request.
