Will be described with reference to FIGS. 7 and 8. FIG. FIG. 7 is a flowchart showing the first half steps of the sound emitting operation of the present embodiment, and FIG. 8 is a flowchart showing the latter half steps of the sound emitting operation of the present embodiment.

When the alarm output clock according to the present embodiment emits an alarm sound or a time alarm at a predetermined time, the reference terminal t7b of the clock input circuit 7 shown in FIG. The drive signal is input, the determination in step S1 of the flowchart in FIG. 7 is YES, and the control circuit 5 causes the input circuit power supply circuit 8
Is activated, the power supply voltage is supplied to the clock alarm mode selection circuit 6 in step S2, and the currently set clock alarm mode is taken into the control circuit 5 from the clock alarm mode selection circuit 6. At the same time, a power supply voltage is supplied from the input circuit power supply circuit 8 to the melody type determination circuit 9 and the melody sound source number determination circuit 10, and the process proceeds to step S3, where the melody sound source cassette 2A is connected to the control circuit unit 1. Is determined.

If it is determined in step S3 that the melody sound source cassette 2A is connected to the control circuit unit 1, the process proceeds to step S4, where the control circuit 5 activates the cassette power supply circuit 12 and activates the melody. A power supply voltage is supplied to the sound source cassette 2A.

Next, the control circuit 5 controls the cassette control circuit 1 based on the judgment signal from the cassette type judgment circuit 9.
1, the address of the melody sound source cassette 2A is set by the cassette control circuit 11, and in step S6, the power supply circuit 16 for the amplifier is activated by the control circuit 5 to supply the power supply voltage to the amplifier 14. Is done.

Then, proceeding to step S7, the control circuit 5 determines whether the mode signal fetched from the clock alarm mode selection circuit 6 is the fixed mode or the daily mode.
First, the case of the fixed mode will be described. The data of the tune of the read number data corresponding to the tune name specified in advance is read from the melody generating circuit 19, and is specified in advance by the sound emitting device 15 via the amplifier 14.

Next, the case where the clock mode taken in by the control circuit 5 from the clock alarm mode selection circuit 6 is a daily mode will be described. The control circuit 5 adds +1 to the previously read tune number data and stores it. The read music number data is read from the memory, and the operation of outputting audio data from the cassette in step S7 is performed. Then, at the end of the output of the audio data from the cassette in step S12, the music read number data obtained by incrementing the currently read music number data by one is stored in the memory of the control circuit 5.

The type of the cassette and the song number data corresponding to a plurality of voice messages or the song number data corresponding to a plurality of FM power sources are determined. Sound operation is performed,
The monitoring operation is performed in the same manner as in the case of the melody sound source cassette 2A.

As described above, according to the present embodiment, the presence / absence of the cassette is determined by the cassette type determination circuit 9 of the control circuit unit 1 when the cassette is mounted.
The attached cassette is the melody sound source cassette 2A,
The type of the FM sound source cassette 2B or the sound source cassette 2C and the model characteristic data in the format are read out, and the number of sound sources of the installed cassette is judged by the cassette sound source number judging circuit 10, and these judgments are made. Based on the data and the clock mode taken in from the clock alarm mode selection circuit 6, a sounding operation is performed by audio data from the mounted cassette. In this case, if it is determined that the cassette is not mounted, or if it is determined that the cassette has been removed during the operation, the control circuit 5 performs a sounding operation by the electronic sound from the electronic sound generating circuit 13. Even if the cassette is not mounted due to a user's erroneous operation, the sounding operation does not stop, and the function as a sounding clock is exhibited. Also, the number data of the next read sound source is set based on the read state of the plurality of sound sources of the mounted cassette and the clock mode, and stored in the memory of the control circuit 5, so that the set clock is always set. Depending on the mode, a sounding operation of an alarm sound or a time signal sound is accurately performed.
