JPS6278793A - Music selecting and reproducing device - Google Patents

Abstract

PURPOSE:To reproduce easily many pieces of desired music by presetting and skipping the undesired music for reproduction of desired music. CONSTITUTION:The numbers of undesired music, i.e., the music to be deleted are preset at a key presetting part 1 and this information is sent to a control part 2 which performs the overall control of a music selecting/reproducing device. Then the numbers of music to be detected are stored in a memory serving as a part of the part 2. At the same time, the part 2 controls the func tion of a reproduction part 3 to reproduce continuously only the desired music. Thus the undesired music are automatically skipped and only the desired music can be continuously reproduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a music selection and playback device, and more particularly to a music selection and playback device that selects and plays only desired songs from a large number of songs recorded on an information recording medium.

[Background of the Invention] As described in Japanese Patent Laid-Open No. 55-89965, when a conventional music selection/playback device wants to select and play only a desired song from a large number of songs on a magnetic tape, it selects and plays the first song of the desired song. When you preset the number starting from the beginning and start the song selection operation, it will fast forward and start playing from the beginning of the desired song. In addition, recently released CD (compact disc) players have a function of sequentially presetting desired songs to be played and selectively playing the songs. However, if there are a large number of desired songs, presetting them is time-consuming and troublesome.

[Object of the Invention] An object of the present invention is to provide a music selection and playback device that easily plays a large number of desired songs.

[Summary of the Invention] The present invention is to preset songs that are not desired to be played so that the songs can be skipped.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIG. 1st
In the figure, when a key preset unit 1 presets a song that is not desired to be played, that is, a song number that is to be deleted, this information is sent to a control unit 2 that controls the entire music selection and playback device, and a memory that is a part of the control unit and memorize the song number to be deleted.

Furthermore, the control unit 2 controls the movement of the playback unit 3 to continuously play back only the songs that the player wants to play.

Next, the processing of the control section 2 will be explained with reference to FIG. Figure 2 shows the case of a CD player that plays CDs (compact discs). Song information is recorded inside the CD disc, and the CD player reads the song information when the disc is driven after the disc is inserted. It looks like this.

Step 1: Here, it is determined whether or not the music is being played, and if it is, the process jumps to the deletion mortar skipping routine from step 2 onwards.

Step 2: Here, the number of the song currently being played is imported.

Step 3: Determine the song number imported in step 2. If it has changed from the previous time, proceed to step 4; if not, exit from this process.

Step 4: Enter the changed song number into the song number comparison register A.

Step 5: Compare the song number comparison register A with the song number in the deletion memory to determine the next song number to cue. If there is no track number to cue, the process proceeds to step 8; if there is, the process proceeds to step 6.

Step 6: The track number to be cued comes into register A, so it is determined whether a jump is necessary or not. If a jump is not necessary, exit, and if it is necessary, go to step 7.

Step 7: Perform the process of skipping to the beginning of the song.

Step 8: If there is no track number to cue next, perform stop processing.

As described above, a process is performed in which the song number stored in the deletion memory is skipped and played.

According to this embodiment, by improving the liftware of the microcomputer constituting the control section, it is possible to skip the song to be deleted.

Figure 3 shows the case of a tape recorder, where there is a gap of about 4 seconds between one song and the next, and the tape recorder detects the gap between songs and reads the song number. The processing of the control section 2 in FIG. 1 is as shown in FIG. 3, and similar effects can be obtained.

[Effects of the Invention] According to the present invention, by simply presetting the song number of the song you want to delete, you can automatically skip the songs you don't want to listen to and continuously play only the songs you want.
