It is a switching unit which performs a switching operation so that the alarm sound from the alarm generation part 38 may be output.

Taking the apparatus configured as described above as an example, a weather alarm operation by the weather time alarm device using the broadcast time reservation function employed in the present invention will be described based on the flowchart of FIG.

Once, in step 200, the microcomputer 34 determines whether the timing function is turned on. If the timing function is turned on (that is, the broadcast time reservation data by the remote controller 24 or the key input unit 28 is inputted). In the step 210, the microcomputer 34 reads the scheduled broadcast start time from the broadcast time reservation day input by the remote controller 24 or the key input unit 28 and stored in the storage means 30, and step 220 The current time is read out based on the clock signal generated by the clock generator 38. Thus, in step 230, the microcomputer 34 determines whether the reservation time (ie, broadcast start time) and the current time match. As a result of the determination, if the two times do not match, the microcomputer 34 returns to step 220 to continue the current time reading operation. On the contrary, when the two times (i.e., the reservation time and the present time) coincide, the power supply 40 applies a predetermined operating power to each component under the control of the microcomputer 34 in step 240, thereby Will be turned on. Thereafter, in step 250, the tuner 10 tunes to the reserved channel based on the pre-international language signal from the microcomputer 34. Subsequently, the broadcast signal tuned by the tuner 10 in step 260 is reproduced through the video / audio reproducing means 1 and output through the CRT and the speaker SP. In this case, the microcomputer 34 in step 270. Determines whether the alarm function is turned on in the broadcast time reservation data.

As a result of the determination, when the alarm function is not turned on, the microcomputer 34 controls the switching unit 42 so that the output terminal of the volume control unit 20 and the input terminal of the voice amplifier 22 are connected in step 280. In addition, the reserved volume level is read from the broadcast time reservation data stored in the storage means 30, and the volume control unit 20 is controlled based on the read volume level. Accordingly, the voice adjusted to the volume level reserved by the volume control unit 20 (for example, a level enough to wake the sleeper) is output through the speaker SP, so that the sleeping person is sleeping. do.

However, when the alarm function is turned on, in step 290, the microcomputer 34 controls the switching unit 42 so that the output terminal of the alarm generator 38 and the input terminal of the voice amplifier 22 are connected. Since the alarm generator 38 is controlled, a predetermined alarm sound (eg, "beep" sound) from the alarm generator 38 is amplified by the voice amplifier 22 and then the speaker SP. Is output via Accordingly, the sleeper wakes up by the alarm sound. Thereafter, in step 300, the microcomputer 34 determines whether a predetermined key operation signal (for example, a signal for turning off the alarm function) is input. When the key operation signal is not input (for example, the weather) In the case of being in a lesser sleep state, the alarm sound generator in step 290 is controlled continuously, while the predetermined key operation signal is input to the volume under the control of the microcomputer 34. A voice based on a predetermined volume level, not a voice based on weak data, is output through the speaker SP.

On the other hand, the present invention is not limited only to the above embodiments, but can be modified and modified without departing from the scope of the present invention. For example, in the above-described embodiment, when the alarm function is turned on, the alarm generator generates an alarm sound such as a "beep" sound and outputs it through the speaker, but a voice signal or melody such as "weather time. Please wake up" and the like. May be output.

According to the present invention as described above, when the user inputs the function signal according to the broadcast time reservation, when the alarm function is off, the sleeper wakes up by the broadcast voice based on the volume reservation data, while the alarm function When it is turned on, the sleeper wakes up by a predetermined alarm sound, and thus, when the predetermined volume level is low, the sleeper wakes up more reliably than the conventional method in which the sleeper wakes up.
