Field of the Invention The present invention relates to a remote control transmitter for remotely controlling a performance device for performing music according to music using infrared rays. 2. Description of the Related Art From the spread of karaoke using this kind of remote control transmitter to the world to the present day, a table of contents has been referred to for selecting karaoke music. When performing remote control, a music code corresponding to the selected music piece may be input into the remote control transmitter. This music code may be found by referring to information such as the music title, singer name or index described in the table of contents book. As described above, in the conventional reservation method, music selection and reservation are shared. The music selection is performed manually using a table of contents, and the reservation is a simple one in which a music code is entered. [0004] However, in the above-mentioned conventional remote control transmitter, the system of music codes handled with the performance device differs depending on the model (including the difference between manufacturers). . For this reason, if the model of the performance device is different, the user has to enter a different music code by a different operation each time, and if the manufacturer is different, the way of operation itself changes, so from the selection of music to reservation. There has been a problem that the user is burdened with the procedure. In particular, it is troublesome for those who operate the remote controller for the first time or those who rarely visit the shop to learn the operation. If the operation is different every time you go, this will reduce the enjoyment of karaoke. In addition, since the description of the table of contents differs depending on the model, there is a problem that it takes time to select music until a reservation operation is performed. [0005] The present invention has been made in view of the above-described conventional problems, and its object is to use a table of contents without using a table of contents.
It is another object of the present invention to provide a remote control transmitter capable of easily searching for and selecting a desired music piece without being conscious of the model of the karaoke apparatus, and transmitting a reservation signal.

Is pressed and the cursor key 10g is pressed up or down to scroll the screen forward or backward. Copying is performed by pressing the screen switching key 10e and the copy key 10f. Next, a method of managing music data will be described. FIG. 3 is an explanatory diagram showing an example of a storage format for managing information for specifying music in the present embodiment, and FIG. 4 is an explanatory diagram showing an example of flag information at the time of wireless transmission in the present embodiment. . In this embodiment, as shown in FIG.
Information for specifying the music is stored in 26c. This information includes, for example, a song title, a singer's name, duet information, the best 100 songs, a singer's name index, and a song name index, all of which are compressed and stored, and are decompressed when displayed. For example, as shown in FIG. 3, for a music title file, music codes (C
1, C2, C3, C4 ...) and their titles (TIT
LE1, TITLE2, TITLE3, TITLE4 ・
..) are stored in association with each other. When any one of the above-mentioned reservation key 10b and reservation cancel key 10c is depressed, a flag shown in FIG. Is added. In the case of reservation, a reservation flag indicated by R is added, and in the case of reservation cancellation, a reservation cancellation flag indicated by RC is added. These additions form a reservation code or a reservation cancellation code. When sending data to the infrared transmitter 20,
Both the reservation code and the reservation cancellation code have a command format handled by the performance apparatus 50 of the transmission destination. Next, the operation will be described. 5 and 6
7 is a flowchart illustrating a reservation operation according to the present embodiment, and FIG. 7 is a diagram illustrating a display example according to the present embodiment. When the power is turned on by the power switch 12, the operation unit 10
Is detected (step 101). In this embodiment, since the new music data is sequentially added to the RAM 26c, the state of attachment of the memory card 22 is detected at the time of copying. Then, when the copy key 10f and the screen switching key 10e are pressed and a copy is instructed (step 102), the mounted state of the memory card 22 is detected from the card detection and data reading unit 24 (step 1).
03). When the memory card 22 is inserted, commander model information indicating a command corresponding to the performance device is read. The read commander model information is compared with the commander model information of the performance device 50 registered in the ROM 26b in advance (step 105). As a result, if they match, the music data is read from the memory card 22 and stored in the RAM 26c (step 106). In this way, new music data is added. If they do not match, a message is displayed on the display unit 18 as the model mismatch (step 107). If the memory card 22 has not been mounted in step 103, a message indicating that the memory card 22 has not been mounted is displayed (step 108). If the key input is by the character key 10a, the music title file in the RAM 26c is referred to in correspondence with the input character, and the title of the music title is displayed (step 110). For example, when the character key 10a for displaying the head of the "A" line is pressed, as shown in FIG.
The title of the song on the first page of the “A” line is displayed at the beginning. In the screen control, the cursor key 1
When 0g is pressed, whether the button is pressed upward or downward is detected, and processing for controlling the position of the cursor on the display screen is executed. For example, when the downward movement is instructed four times by the cursor key 10g, the movement of the cursor C is controlled to the position of the cursor C 'shown by the dotted line as shown in FIG. When the cursor key 10g and the screen switching key 10e are pressed (step 113), the screen is scrolled up and down in response to an instruction to move the cursor key 10g upward or downward (step 114). . The screen control is performed in this manner. Further, in the reservation control, the reservation key 10b
Is pressed (step 115), the music corresponding to the music title where the cursor C is located is reserved. For example, when the cursor C is moved to the position of the song title “TITILE1” shown in FIG. 3 and the reservation key 10b is pressed, the song title “TITILE1” is pressed.
The music code C1 corresponding to "LE1" is detected. A reservation code is formed by adding the reservation flag R shown in FIG. 4 to the music code C1 (step 11).
6). This reservation code has a command format corresponding to the model of the performance device 50. Thus, the infrared transmitter 20
The reservation code is converted into an infrared signal at
The infrared signal is transmitted to the receiving means 50a of the performance device 50 (step 117). When the reservation cancel key 10c is depressed in the same manner as the reservation control, the reservation cancellation key 10c is changed according to the music title where the cursor C is located at that time and the music code corresponding to the music title and the reservation cancellation flag RC (see FIG. 4). A reservation cancellation code is formed by integration (steps 118 and 119). Then, the reservation cancellation code is converted into an infrared signal, and the infrared signal is converted to the performance device 50.
Is transmitted to the receiving means 50a (step 120). In the performance device 50, a process for canceling the reservation of the music already reserved is executed according to the reservation cancellation code. In step 118, the performance stop key 10
When the input of d is detected, a predetermined performance stop code is converted into an infrared signal, and a process of transmitting the infrared signal is executed (steps 120 and 121). As described above, according to this embodiment, the music data is read from the memory card 22 and
c, the music data such as a new musical score can be added as needed, and the database of the main unit 1 itself can be updated accordingly. With this, it is possible to prepare so that the latest music can be reserved at any time. Further, as information for specifying the music, a music title, a singer's name, or an index can be displayed as in a table of contents book, so that it is easy to visually specify the music. Also, since the music is specified on the display screen, it is easy to search for the music, which facilitates the music selection. Further, the apparatus 1 itself can store the latest new music information without referring to the table of contents book, search for it, and even reserve (wirelessly transmit) music. In this way, anyone can reserve songs with simple operation procedures regardless of the model of the performance device,
It reduces the burden on the user. A character key 10 corresponding to a headword
Since a is provided, a desired heading can be directly cued and displayed by operating the character key 10a, and other keys can be displayed. As described above, the music selection operation can be realized with a simple configuration. Since the music data is managed in accordance with the model of the performance device, the music data can be managed only by the same model. As a result, the remote control transmitter can be exclusively used for each model, and there is an advantage that a remote control transmitter corresponding to any model can be reserved by the same operation. Furthermore, since the database can be updated on the RAM 26c even when a new musical score is produced, it is possible to eliminate the uneconomical effect of binding a table of contents every time a new musical score is produced as in the related art. In the above-described embodiment, the music data database is constructed in the RAM 26c or the RAM 26c 'of the control unit 26. However, a writable memory such as a flash ROM may be applied. As the above-mentioned memory card 22, for example, a card such as a RAM card, a ROM card, a magnetic card, a magneto-optical card, an IC card and the like can be applied. Further, in a restaurant or the like, since the illumination may be dark, the display section 18 may be provided with an illumination section. Thus, the display screen is illuminated brightly, so that characters can be more easily read from the display screen. In the above-described embodiment, one commander model is used for one machine 1. However, a plurality of types of commander models can be supported by increasing the memory capacity by the RAM 26c or another memory configuration. You may do it. In this case, the commander model may be determined at the time of reading from the memory card, and the commander model may be written in a predetermined storage area preset for each model. Switching of the commander model when making a reservation or canceling a reservation may be performed by providing a key for switching the commander model on the operation unit 10 or by setting a soft switch using a display screen. Although the memory card 22 is used as a recording medium in the above-described embodiment, the present invention can be applied to a recording medium such as a compact disk or a floppy disk. In this case, the size of the apparatus 1 and the card detection and reading configuration of the data reading unit 24 may be changed as appropriate according to the type of each recording medium. Furthermore, in the above-described embodiment, the screen switching is performed by scrolling the screen switching. However, the screen switching may be simply switching to the previous page or the next page, or may be added. . As described above, according to the present invention, since the music data is read out from the recording medium and stored, it is possible to add music data such as a new music as needed and update its own database. . With this, it is possible to prepare so that the latest music can be reserved at any time. Since the music is specified while displaying information for specifying the music, the music can be used not only to simply select the music and select the music, but also to search for the music. Further, since information for specifying music is wirelessly transmitted, the remote control transmitter itself can store the latest information without searching the table of contents, search for it, and even reserve music. Therefore,
Anyone can reserve songs with simple operation procedures. In the present invention, since the music data for music selection reservation for a karaoke performance device of a specific model is stored in a database and managed, the remote control transmitter is exclusively used for each model. can do.
