Abstract

PURPOSE:To prevent a miss at the time of recording by adding a time for interval, which is provided between the pieces of music by an automatic space key, to a total playing time to be displayed for the plural designated pieces of the music. CONSTITUTION:For playing time adding operation, at first, 0'00'' is inputted to an X and '1' showing an order for the pieces of the music in a program is inputted to an (n). The playing time for the n-th designated piece of the music is inputted to a Y and the time for the interval to the next piece of the music is added to the Y. Next, (X+Y) is inputted to the X and (n+1) is inputted to the (n). The contents of the X are displayed in a display part. In such a way, the total time for the intervals between the piece of the music to be played and the next piece of the music are added to the total playing time for music numbers designated for music selection and the total time for the intervals is displayed. As a result, even when the recording is executed by using a cassette tape matched to the total value of the displayed playing time, the final piece of the music is not cut off like a conventional CD player.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a CD (compact disc) player with a music selection function, and in particular to a blank time set between a song being played and the next song. The total leap time of the specified song is displayed, taking into account the following. By the way, this blank space is used when recording successive songs played by a CD player on a cassette deck (table recorder). This is for automatically detecting. [Prior Art] Conventionally, as a CD player, a CD player with a song selection function is known in which the order of songs to be played on a CD is specified in advance and the songs are played in accordance with the specified order. ．． Such a CD player with a song selection function reads data from the CD to be played, calculates the playing time of the specified song from this data, adds up the calculated playing times one after another, and calculates the playing time of the specified song. There is one that displays a leap line when playing.

, rl2J, the total performance time of the specified song is calculated as follows.

Song number Performance time 3 15 minutes OO seconds 8 7 minutes 12 seconds 9 3 minutes 42 seconds These total values are displayed on the display section 4 described above. Looking at the total performance time displayed on the display 4, select a cassette tape that matches this, in the above example a C60 (only side A is used). There is. In addition, the above-mentioned auto space key 8 sets a blank time between a song played by the CD player and the next song, that is, a time period in which no song is played between one song and the next song. As a result, a cassette tape on which a song from a CD player is recorded has a section 11 where the song is recorded and a section l2 where the next song is recorded, as shown in the cassette tape 10 shown in Fig. 3. In between, there is a blank area l3 where no songs are recorded, and this blank area l3 is used by the cassette recorder to count the number of songs on the cassette tape, select songs, and cue the beginning. [Problems to be Solved by the Invention] In the above-described conventional CD player with a song selection function, when specifying a song for the song selection, the auto space key 8 is operated to make a difference between the songs to be played and the song. Even if you set a blank time in between, this blank time was not added to the total displayed performance time of the specified song. There were times when a cassette tape of the length suitable for the time could not be recorded completely, and the last song was cut off. This invention is above! ! This is to solve problem a, so that the blank time leaps provided between songs by the auto space key 8 can also be added to the total performance time leaps displayed for a plurality of specified songs. This is what I did. [Means for Solving the Problems] In order to solve the above problems, in this invention, as shown in FIG. 1, the songs to be played are specified in order and the songs are played in this order. In a CD player with a song selection function, which has a blank space between a song to be played and the next song, the total playing time of the specified song and the blank space are The apparatus includes means for adding up the total time as a result, and means for displaying the added time.

[Function] In the CD player with a song selection function of the present invention configured as described above, the blank time between one song and the next song is added to the total performance time of a plurality of specified and displayed songs. It will be added. [Example 1] An example of the present invention will be described below with reference to the drawings.
