<Problems with the Prior Art> However, depending on the set time, the broadcast station set for 14-hour wake-up may not be broadcasting, and in this case, there is a problem in that no sound is output even when the wake-up time arrives. Furthermore, in car radios and the like, there are times when it becomes impossible to receive broadcasts at a preset frequency due to the movement of the car, and in this case as well, there is a problem in that no sound is output even when it is time to wake up.

<Summary of the Invention> The present invention has been made in order to improve the drawbacks of the conventional radio receiver with an alarm function described above, and includes a timekeeping means for counting one hour, an alarm time setting means for setting an alarm time, and a clocking means for counting one hour. means for storing an alarm time set by the setting means; means for detecting coincidence between the time measured by the clocking means and the time stored in the storing means; and receiving by a detection signal from the detecting means. a control means for setting the circuit to a reception state, a reception detection means for detecting whether or not the reception circuit is receiving broadcasting, a means for automatic tuning when no reception is detected by the reception detection means; means for outputting audible broadcasts received by the receiving circuit; means for outputting an alarm sound generation signal when the broadcast is not received even after automatic channel selection by the automatic channel selection means; The basic feature is that it has a means for outputting sound.

Effect> In the above configuration, when the time coincidence is detected by the time coincidence detection means, the receiving circuit enters the broadcast reception state. Then, the reception detecting means detects whether or not the receiving circuit is actually receiving the broadcast, and when the broadcast is not being received, the automatic tuning means automatically performs channel selection and the broadcast is not received (a). be done.

This received broadcast is output from the audio output means and functions as an alarm for waking up.

If the broadcast is still not received even after automatic channel selection, an alarm sound generation signal is output, and an alarm sound is output from the alarm sound output means.

<Example> An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, reference numeral 1 denotes a clock as a timekeeping means, and the output of this clock is input to a time coincidence detection device 4.

Reference numeral 2 denotes an alarm time setting device for setting a desired alarm time, and the alarm time can be set by operating the operating means 11. The alarm time set to 1 by the alarm time setting device 2 is sent to the alarm time storage device 3 and stored there. The time coincidence detection device 4 constantly compares the time stored in the alarm time storage device 3 and the current time from the clock 1, and when the two match, the coincidence signal is turned on/off to the FF control device 5. It is configured to output . 0N10F
The F control device r15 is for 0N10FF control of the power supply of the radio receiver, and receives the coincidence signal from the time coincidence detection device 4 and turns on the power, thereby controlling the reception circuit 1.
0 is set in the receiving state.

ON / OF F Turn fM display device 5 receiving circuit 10 to O
At the same time as setting it to N, the S meter signal detection device 6 is also put into operation. The S meter signal detection device 6 is a reception detection means that detects whether or not the reception circuit 1O, which has entered the reception state by the 0N10FF control device 5, is actually receiving broadcasting.
Broadcast reception is checked by manually inputting an S meter (signal meter) signal from the receiving circuit 1o.

If the S meter signal is not sent from the reception (ti circuit 10), the S meter signal detection device 6 sends a signal to the automatic tuning control device 7 indicating that there is no reception (a detection).

Self! 1! The IJ tuning control device i\7 performs automatic tuning such as a so-called seek operation, and is configured to perform automatic tuning such as a so-called seek operation.
The receiver circuit 10 is configured to change the receiving frequency of the receiving circuit 10 while inputting a signal (signal Detection), and to cause the receiving circuit 10 to receive that frequency when an SD multiplied signal is present.

FIG. 2 shows details of one embodiment of the automatic channel selection control device 7.

Seek operation 0N10 FF The F control device 71 detects the receiving circuit 10 by the broadcast non-reception signal from the S meter signal detection device 6.
After performing a seek operation and performing a seek at a predetermined period,
The receiving circuit 10 is made to stop the seek operation. SO(: No. 1 detection device 7o detects the SD double signal from the receiving circuit 10,
If not detected, a signal of non-detection is sent to the seek cycle detection device 72.

The seek cycle detection device 72 determines the cycle of the seek operation, and if it does not reach a predetermined number of times, the seek sensitivity switching bag 5!
A signal is sent to 73 to switch the seek sensitivity and perform a seek. If the predetermined number of times has been reached, the seek cycle detection device 72 sends a signal to the seek operation 0N10FF control device 71 to stop the seek operation of the receiving circuit 10 as described above. The seek cycle may be any number of cycles as long as it is one or more cycles.

Note that the receiving circuit 10 is equipped with a tuner that changes the reception frequency according to a control signal from the automatic channel selection control device 7.

The output of the receiving circuit 10 is input to an audio output device 12, where it is output as audio.

If the broadcast is not received by the seek operation of the automatic channel selection control device 7, the S meter signal detection device 6 sends a signal indicating that the broadcast is not received to the ON10 F F control device 5.
a. Upon receiving this signal, the 0N10FF control device 5 turns off the power to the radio receiver and also issues an alarm 0N1.
0FF operates to control device 8 (sends No. 3. Alarm 0N
The 10 F F control device 8 causes the alarm 9 to generate a predetermined sound as an alarm sound based on this activation signal. The alarm 9 may be separate from the radio receiver, or may be configured inside the radio receiver using a part of its configuration. Then, an alarm sound may be outputted from the audio output bag vL12. In this case, if there is no broadcast reception, the 0N10FF control device! i! 15 so that the radio reception AM source is not turned off or the +11η component of the alarm 9 is kept powered.

A time display device 13 displays the time measured by the taro clock 1, the time set by the alarm time setting device 2, and the like.

Next, the operation will be explained.

The operator first operates the operating means 11 to set a desired alarm time. By this operation, the alarm time is set in the alarm time setting device 2, and the set alarm time is stored in the alarm time storage device 3. The time coincidence detection device 4 compares the measured time from the clock 1 and the alarm time from the alarm time storage device 3, and outputs a coincidence signal to the 0N10FF control device 5 if the two coincide.

The 0N10FF control device Fj5 activates the S meter signal detection device 6 using the coincidence signal, and also transmits an activation signal to the receiving circuit 10 to set the receiving circuit 10 in a receiving state. The S meter signal detection device 6 inputs the S meter signal from the receiving circuit 10 and checks whether the receiving circuit 10 is actually receiving the broadcast.

If the receiving circuit 10 is receiving a broadcast, the received content is converted into audio by the audio output device 12 and functions as an alarm. If there is no S meter signal and no broadcast is being received, a signal indicating that no reception has been detected is transmitted from the S meter signal detectors 5 to 6 to the automatic channel selection control device 7. The automatic channel selection control device 7 performs the above-described seek operation in response to this signal, changes the frequency sequentially, and causes the receiving circuit 10 to receive other broadcasts. In this embodiment, the seek operation is configured to perform two rounds, and the first round of the seek is for narrow band (local) reception, and only stations with strong electrolytic strength and which can be clearly received are searched. Then, if there is no station that can be received on the 511th round, 2
The configuration is such that wideband (Dx) reception is performed on the first round and a 1-weak electric field is also searched.

When the receiving circuit 10 receives another broadcast, the received content is sent to the ff voice output device 12, where it is converted into voice and functions as an alarm.

If the broadcast is still not received even after the seek operation by the automatic channel selection control device 7, a signal indicating that the broadcast is not received is sent from the S meter signal detection device 6 to the 0N10FF control device 5, and the ON/○FFN/type setting 5 is Turn off the radio receiver power?
Alarm ON/○rr F control device i when set to F
Send a working signal to '78. In response to this signal, the alarm 0N10FF control device 8 activates the alarm 9 and outputs a predetermined alarm sound.

As described above, since the alarm sound by the alarm 9 is output even if the broadcast is not finally received, a reliable alarm operation can be obtained.

FIG. 3 shows another embodiment constructed using a microcomputer 2o.

The microcomputer 20 inputs the S meter signal and the SD multiplied signal from the radio receiver main body 30, and outputs the control voltage Vt and wideband reception signal Dx to the radio receiver main body 30. The radio receiver main body 30 includes components similar to the above-described receiving circuit 1o and audio output device 12, and also includes a control voltage Vt and a wideband received signal D.
A tuner is provided to change the receiving frequency band in accordance with x. The power supply circuit 31 of the radio receiver body 30 is controlled by the microcomputer 20.

The configuration is such that the radio receiver main body 30 can be put into a receiving state by detecting a coincidence of times.

A microcomputer 200 board 23 and an output port 24 are each connected to a key matrix 22. The key for setting the time is also a key matrix 22
It is prepared for. A display device 21 is connected to the microcomputer 20, which is configured to display necessary information such as the set time and current time.

The microcomputer 2 is
The operation of 0 will be explained.

The microcomputer 20 checks whether the alarm setting key in the key matrix 22 has been pressed (step 4o), and if it has not been pressed, performs normal separate processing (step 51); if it has been pressed, sets the alarm. The alarm time set by the key is memorized, while the timer built in the microcomputer 20 measures the time and constantly checks whether the alarm time has arrived (
Step 41), [When the jib time arrives, the power supply circuit 3
1 to operate the radio receiver main body 30 and bring it into a receiving state (step 42). When a broadcast is received at a frequency preset in the radio receiver main body 30, the broadcast is outputted as an alarm from the radio receiver main body 3o. At this time, the S meter (No. 8 is LO
The microcomputer 20 checks this S meter signal (step 43), and if it is LO, the control voltage Vt is not changed and the frequency is maintained by the radio receiver body 30 (step 44).

When the S meter signal is H, the control voltage Vt is sequentially changed to cause the radio receiver body 30 to perform a seek operation (step 45). During this operation, the microcomputer 20 checks the SD double signal from the radio receiver body 30. Step 46), this signal is turned off, and when the radio receiver body 30 receives another broadcast, the frequency is maintained (step 47). As a result, other broadcasts are received by the radio receiver main body 30 and outputted as an alarm.

In this embodiment, the seek operation is configured to perform one cycle, and it is checked whether or not the receiving frequency band has been completed once (
In step 48), if there is no received broadcast after completing one cycle of the seek operation, the microcomputer 20 outputs the m source OFF signal to the radio receiver main body 30 and turns off the power (
Step 49).

The microcomputer 20 then outputs a signal to the alarm 32 to generate a predetermined alarm sound (step 5).
0).

As explained above, in the above configuration, even if there is no broadcast on the preset frequency, it will automatically seek and receive other stations, so the broadcast will be heard at the set alarm time when the broadcast ends or the car moves. There is no possibility that the alarm will not be output, and reliable alarm operation can be obtained. Furthermore, if the broadcast is not received even after the seek operation,
Since an alarm sound is outputted by the alarm, the alarm is reliably outputted, and it is possible to completely prevent an accident in which the alarm output is not obtained.

Therefore, it is suitable for radio receivers with a conspicuous function for napping on large trucks, etc., and is also suitable for use with various other radio receivers.
