DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an optical disc playback device such as a compact disc player.

2. Description of the Related Art Conventionally, this type of optical disc player has been constructed as shown in FIGS. 6 to 9.

That is, 1 is an optical disc (hereinafter simply referred to as a disc)
2 is a signal detection section consisting of an optical pickup, etc. that reads the music information and performance time information recorded on the top; 2 is a signal output section that processes the information read by the signal detection section, converts it into an audio signal, and outputs it; 3 is a signal detection section for these signals. Section 1 and signal output section 2
A part of the control section includes an addition/subtraction time display control section 6, which will be described in detail later. Reference numeral 4 indicates a display section that displays the performance time read by the signal detection section 1 and input information from the key switch section 6 via the control section 3; and 6 a play key 5a that instructs the control section 3 to start playing; This key switch section includes a playback time type key sb for specifying the duration to be continued to the control section 3, a memory white key 6c for storing the song desired to be played, and the like.

The addition/subtraction time display control section 6 includes a designated playback time storage section 8 that stores the playback time specified by the playback time input means 7.
, a playback song storage unit 10 that stores the song number specified by the memory song input means 9, a memory song playback time addition unit 11 that calculates the sum of the playback times of the stored songs, and a memory song playback time that is calculated from the specified playback time. The subtraction means 12 is used to subtract the sum of the subtraction means 12, and the time display means 13 is used to display the data obtained by the subtraction means 12 in numerical form.

With the above configuration, control as shown in the flowchart of FIG. 9 was performed.

That is, in step 1, it is determined whether or not the play key 6a has been pressed, and if it has been pressed, the process moves to step 10, and if it has not been pressed, the process moves to step 2.

In step 2, it is determined whether or not the playback time Tp has been input. If there is no input, the process moves to step 3, and if there is, the process moves to step 4. At this time, the initial value of T is set to 0. In step 3, in order to determine whether the process has proceeded to step 4 at least once, it is determined whether Tp is equal to 0. If they are equal, the process returns to step 1, and if not, the process proceeds to step 4. In step 4, it is determined whether or not there is an input for storing the played song. If there is no input, the process moves to step 6, and if there is, the process moves to step 6. In step 6, it is determined whether there is a regenerative memory mortar,
If there is, go to step 8 and go to step 6; if not, go back to step 1. In step 6, each time a stored song is inputted, the stored song playback time addition section adds the playback time to Trn in order to obtain the sum Tm of the stored song playback times, and the process moves to step 7. In step 7, the subtraction means 12 subtracts the sum TTn of the stored music playback times from the designated playback time to obtain the remaining time T11, and the process moves to step 8. In step 8, the remaining time T8. It is determined whether the value is smaller than 0, and if it is not smaller than 0, the process moves to step 9, and if it is smaller than 0, the process moves to step 12. In step 9, the time display means 13 displays the remaining time on the display section, and the process returns to step 1.

In step 12, the numerical display means 13 displays a negative number on the display section to indicate insufficient time, indicating that all the stored songs cannot be completely reproduced within the designated reproduction time, and the process returns to step 1. In step 1°, the signal detection section 1 and the signal output section 2 play music information recorded on the disk. In step 11, the signal detection unit 1 reads the performance time information from the disc, compares the performance time with the specified playback time specified in step 2, and determines whether the performance has ended. If the performance has ended, the process returns to step 1. , if not completed, repeat steps 10-11. Furthermore, if the performance duration time is not specified, it is determined that the performance has ended based on the performance end information on the disc.

Problems to be Solved by the Invention However, the conventional configuration described above only displays the remaining time, and the total playback time cannot be known unless the operator calculates it in his/her head. . Second, even if the memorized song playback time exceeds the designated playback time, only negative numbers are displayed, so there is a problem that erroneous recognition is likely to occur.
