(S14: Yes), instructs the CD player or the like to start reproduction (S18), and simultaneously sets the CPU interrupt to enable (permitted) (S20).

  This interrupt is generated by a frame synchronization signal during playback of a CD or the like, and the CPU 10 counts and displays lyrics and utters each time an interrupt occurs.

  If the start process is not instructed in the determination process of S14, it is determined whether or not the stop of the reproduction is instructed (S20). If an instruction to stop playback is given, playback on the playback device is stopped (S22), and interrupts are prohibited (S24).

  If the stop process is not instructed in the determination process of S20, the state of an operation element such as another switch is detected, and if the state is changed, the process is performed. For example, selecting a song to be played back from a plurality of songs recorded on a CD or the like, or setting a playback order of the plurality of songs. Even if a recording medium such as a CD is not loaded, the lyrics can be displayed if the insertion history is stored in the insertion CD history database 16b. Further, although the CD is identified and displayed from the newly installed TOC such as a CD, it may be searched again if it is identified by mistake.

  Next, processing that is started when a frame synchronization signal is generated during playback in a CD player or the like will be described with reference to the flowchart of the lyrics processing program 12b shown in FIG. When the start switch is pressed, the frame number f is set to 0, the pointer P1 of the table A that stores time information for displaying lyrics, and the pointer P2 of the table B that stores time information for uttering lyrics Is set to the first data of the table.

  First, the variable f for measuring time is incremented by 1 (S30). At that time, it is determined whether or not the time of the table A indicated by the pointer P1 of the lyrics display table is the current time (S32). When the time information indicated by the pointer P1 coincides with the current time (S32: Yes), the text data of the phrase indicated by the pointer is transmitted to the video board 20, the display of the lyrics is updated, and the pointer P1 is incremented. (S36). In the determination process of S32, when the time indicated by the pointer P1 does not coincide with the current time and when the process of S36 ends, next, whether the time information of the table B indicated by the current time and the pointer P2 is the current time or not. Is determined (S38). When the time information indicated by the pointer P2 coincides with the current time (S38: Yes), the text data of the phrase indicated by the pointer is transmitted to the speech synthesizer 24, and the lyrics are uttered (S40). Is incremented (S42) and this routine is terminated. Further, in the determination process of S38, this routine is also ended when the time indicated by the pointer P2 does not coincide with the current time.

  Note that the time measuring means described in claim 1 of the claims corresponds to the processing of S30 in the flowchart shown in FIG.
