Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to an audio device with a clock.

(b) Prior Art Conventionally, when a preset time arrives, a clock-equipped audio device uses a signal output from a clock section to close a power supply path to a receiver, thereby activating the receiver. is publicly known.

However, in the case of an audio device with a synchronized clock, it is necessary to set the receiver to a tuned state before setting the timer operation time.

This is because the timer operates, so even if the power supply path to the receiver is closed, if the receiver is not in tune, only noise will be heard.For example, the output signal of the receiver may be used as an alarm signal. case,
Not enough.

(c) Problems to be solved by the invention As mentioned above, in the conventional technology, it was necessary to set the receiver to a tuned state before setting the timer operation time, which caused problems in operability.

(d) Means for Solving the Problems In view of the above problems, the present invention includes a clock section, a receiver section, and a key input section including at least a key for setting the timer operation time. The audio equipment with a clock is configured to supply power to the receiver section and thereby perform a timer operation when the time information set by the previous clock matches the current time information of the subordinate clock, a detection section for detecting the tuning state of the receiver section; a tape recorder section; a cassette presence/absence detection section for detecting whether or not a cassette is attached to the tape recorder section; a notification circuit section; and a control section that outputs a control signal based on the detection signal from the presence/absence detection section, the detection section detects that the receiver section is out of tune, and the cassette presence/absence detection section detects that the cassette is inserted. When it is detected that the receiver section is out of tune, the tape recorder section is set to a playback state by a control signal from the control section, and the detection section detects that the receiver section is out of tune. When the cassette presence/absence detection section detects that no cassette is installed, the notification circuit section is set to an operating state by a control signal from the control section.

(E) Effect According to the present invention, when the time information set at the key input section and the current time information from the clock section match, first the tuning state of the receiver section is detected.

At this time, if tuned, the broadcast is continuously received; if not tuned, it is determined whether or not a cassette is installed in the tape recorder section.

If a cassette is attached, the table recorder section is set to the playback state, whereas if no cassette is attached, the notification circuit section is set to the operating state.

(f) Examples FIG. 1 is a diagram showing an embodiment of the present invention.

In Fig. 1, 1 is an antenna, and 2 is a front end that converts the high frequency signal from the antenna 1 into an intermediate frequency signal and outputs it, and includes a well-known high frequency amplification circuit, a local oscillation circuit consisting of a PLL, and a mixing circuit. . 3 is an intermediate frequency amplifier circuit, 4 is a detection circuit, 5 is a low frequency amplifier circuit, 6 is a speaker, and 7 is a microcomputer that controls the division ratio of the programmable frequency divider that constitutes the PLL and has a built-in clock section. The controller 8 is a key input unit connected to the controller 7, and includes at least a key for setting the timer operation time. Reference numeral 9 denotes a level detection unit that detects whether the level of the intermediate frequency signal exceeds a predetermined level, and when a signal exceeding the predetermined level is detected, the controller 7
Outputs the sweep stop signal _S1 to. 10 is a tape recorder section, 11 is a voice synthesis circuit section that serves as a notification circuit,
Reference numeral 12 denotes a switching circuit that selectively supplies the outputs from the detection circuit 4, tape recorder section 10, and speech synthesis circuit section 11 to the low frequency amplifier circuit 5, and outputs control signals _S2 , _S3.
Switching is controlled by . Reference numeral 13 designates a switch disposed in a power supply path 14 to each circuit of the receiver, and is controlled to be turned on/off by a control signal _S4 from a controller 7.

FIG. 2 is a functional block diagram of the present invention. Second
In the figure, reference numeral 15 denotes a control unit composed of a microcomputer, 16 a ROM storing a program executed by the control unit 15, 17 a preset memory in which preset channel selection data is stored, and 18 a timer operation time information and the information stored therein. Data memory 1 for storing a flag “1” indicating that the flag is set;
Reference numeral 9 denotes a clock section, and 20 indicates a cassette presence/absence detection section for detecting whether or not a cassette tape is loaded in the tape recorder section 10. It's a switch.

Next, the operation will be explained with reference to FIG.

After setting the timer operation time by operating the keys on the key input section 8, when the timer key is operated, the time and flag "1" are stored in the data memory 18, and the control section 15 is set to the timer operation mode. Ru.

The control unit 15 accesses a predetermined address of the data memory 18, for example address A, and determines whether the flag is "1" or "0" to determine whether the time has been set or not through the timer operation. (Step 1).

If the value is "1", then data memory 1
It is then determined whether the time information stored in the time register 8 matches the time supplied from the clock unit 19 (step 2). If they do not match, the above-mentioned procedure is repeated, and if they match, the switch 13 is turned on to supply power to the receiver unit (step 3).

Next, it is determined whether the receiver section is in a tuned state based on the output signal from the level detection section 9 (step 4), and if it is in a tuned state, reception is continued.

On the other hand, if the cassette is not in the synchronized state, it is determined whether or not a cassette is attached based on the output signal from the cassette presence detection section 20 (step 5).

At this time, if a cassette is installed, a control signal _S5 is output to the tape recorder section 10 to set it to the playback state. Next, it is determined whether the tape end has been reached (step 6), and if the tape end has been reached, a control signal S ₆ is sent to the tape recorder section 10.
output and stop the playback, and switch 13
turn off.

If no cassette is attached, the speech synthesis circuit section 11 is set to an operating state. The voice notification by the voice synthesis circuit section 11 may be a notification of a set time or a notification that the timer operation is disabled.

After the continuous reception state is set in step 4, access a predetermined address in the data memory 18, for example address B, and check whether the timer operation end time has been set or not, and check whether the flag is set to "1" in the same manner as described above. or "0" (step 7).

If the flag is "0", then power is continuously supplied to set the normal operation mode, and if the flag is "1", the operation end time stored in the data memory 18 and the clock unit 19 supply the power. It is determined whether the times match (step 8).

As a result of this determination, if the two times match, the switch 13 is turned off to end the timer operation.

(g) Effects of the invention According to the invention, when the timer is activated, if the receiver section is out of sync and a cassette is attached to the tape recorder section, the tape recorder section is set to the playback state, and the receiver section is set to the playback state. Since the alarm circuit section is set to the operating state if the tape recorder section is out of synchronization and no cassette is installed in the tape recorder section, the signal can be reliably played back when the timer is operating, and in particular, the playback signal can be used as an alarm. Suitable for use as sound.
