For example, in the illustrated example, when the MD device 15A is used in the playback mode, its output is connected to the speaker 3.

Next, the operation of the in-vehicle signal recording / reproducing apparatus 10 will be described with reference to FIG. Playback unit 14
When an audio signal reproduced from a CD by the CD device 14A is recorded on the MD by the MD device 15A of the recording device section 15, first, a recordable MD is mounted on the MD device 15A,
The recording / pause key of the operation unit 12 is pressed to put the MD device 15A in a recording standby state. Next, a recording end condition is selected. The recording end condition refers to an operation of recording and ending the last recording area of the MD (disc end), or an operation of recording and ending one song in the case of music (track end). When the selection of the recording end condition is completed, the reproduction key of the CD device 14A of the operation section 12 is pressed to start playing (playing) the CD, and at the same time, the recording / pause key of the operation section 12 is pressed again. And the MD device 15
When A is in the recording state, the reproduced audio signal is input to the MD device 15A through the recording signal line 18 and starts recording on the MD.

When the recording state is continuing, the user may want to leave the vehicle. In such a case, the user turns off not only the engine but also the accessory switch 2 with the engine key, removes the engine key from the key switch, locks the door, and leaves the vehicle.

When the accessory switch 2 is turned off, in the in-vehicle signal recording / reproducing apparatus 10 of the present invention, the microcomputer of the system control unit 11 detects a voltage drop of the power supply line 1B input thereto, and Switch 2
Is determined to be disconnected. Accessory switch 2
Even if is disconnected, the power supply to the on-vehicle signal recording / reproducing apparatus 10 is performed through the power supply line 1A, and the reproduction of the CD and the recording on the MD are continued until the recording end condition is satisfied.

However, when the disconnection of the accessory switch 2 is detected, a "display off" command is transmitted from the system control unit 11 to the display unit 13. When the display unit 13 receives this command, the display is turned off. I do. With this function, it is not known that the in-vehicle signal recording / reproducing device 10 is mounted on the vehicle unless the user looks into the vehicle from outside. Further, the power required for lighting the display can be reduced, and the consumption of the battery 1 can be prevented accordingly.

A command of "disconnection" is transmitted from the system control unit 11 to the switch 16, and the switch 16 is disconnected by this command so that the reproduction audio signal from the CD device 14A is not supplied to the speaker 3. . With this function, the power required to level the speaker 3 can be reduced, and the consumption of the battery 1 can be prevented accordingly.

Further, an alarm signal is intermittently transmitted from the system control section 11 to the speaker 3 through the reproduction signal line 19, and is output from the speaker 3. This function allows the user to know that the in-vehicle signal recording / reproducing device 10 is still “recording”. For example, the alarm signal only needs to beep once every 5 seconds, and the alarm signal can be emitted at relatively long intervals to prevent battery consumption.

This alarm is issued until the recording end condition is satisfied. Therefore, the in-vehicle signal recording / reproducing device 10
If the user leaves the vehicle during the recording operation and returns and gets on the vehicle and the alarm signal is still issued, it is known that the in-vehicle signal recording / reproducing apparatus 10 is still performing the recording operation.

Next, if the recording end condition is satisfied,
A command of “operation stop” including “recording stop” is transmitted from the system control unit 11 to the playback device unit 14 and the recording device unit 15, and even if the user is not in the vehicle, the in-vehicle signal recording / playback device is automatically set. 10 playback device unit 14 and recording device unit 1
The supply of power to 5 is cut off and their operation stops.
This function can also prevent the battery 1 from being consumed.

[0035]

As described above, according to the on-vehicle signal recording / reproducing apparatus of the present invention, even when the accessory switch is turned off, when the recording of the audio signal, the video signal and the like is continued, the battery of the vehicle can be used. The user can be informed that the in-vehicle signal recording / reproducing apparatus is continuing recording without burdening the user.

Further, since the display on the display unit can be turned off, it is difficult to visually recognize that the vehicle-mounted signal recording / reproducing apparatus of the present invention is mounted on a vehicle from outside the vehicle.

Furthermore, the consumption of the battery mounted on the vehicle can be reduced.
