Abstract

PROBLEM TO BE SOLVED: To record a desired signal by a simple operation despite a loading play type by stopping the switching of a storage medium to a reproducing operation when the storage medium is loaded after a prescribed manipulator is operated. SOLUTION: When a minidisk is loaded in a state where a sound recording manipulator is previously operated, the switching of a source is discontinued by the control of a system control circuit and a recording standby state is set for the source that is so far viewed in a car audio system. When the sound recording manipulator is pressed, the sound recording is started via the minidisk. Even when the minidisk is reproduced in a loading play, the switching of the source can be omitted after the minidisk is loaded by a previous operation and accordingly the operability of a recording/reproducing device is improved. Furthermore, it's possible to prevent a trouble where a recording medium recording no audio signals is loaded and reproduced.

The display unit 15 includes the liquid crystal display panel 3 described above with reference to FIG. 2 and a drive circuit for the liquid crystal display panel 3, and displays various messages and the like under the control of the system control circuit 12.

The system control circuit 12 is constituted by a microcomputer for controlling the operation of the car audio system 1, and responds to the operation of the operators 5A to 9B.
In response to the notification from the compact disk unit 13 and the mini disk unit 14, a control command is issued to each block.

That is, the system control circuit 12 switches the source of the audio data to be output to the amplifier (not shown) in response to the operation of the operating elements 5A to 5C when the operating elements 5A to 5C for the source selection are operated. Switches the entire operation so that the user can listen to the source desired by the user.

When the compact disk unit 13 is notified of the loading of a compact disk and the mini disk unit 14 is notified of the loading of a mini disk, the system control circuit 12 determines the source of the audio data to be output to the amplifier. Switching to a compact disk or mini-disc, whereby the reproduction of the compact disk or mini-disc is started by loading-play. At this time, the system control circuit 12 turns on the power supply and starts reproduction of the compact disc or mini-disc when the user is notified of the loading of the compact disc or mini-disc in a state where the power is not turned on by the user. .

On the other hand, when the recording operation element 6 is pressed, the system control circuit 12 executes the processing procedure shown in FIG. 1 to control the entire operation. That is, the system control circuit 12 proceeds from step SP1 to step SP2. In this case, since the mini-disc has not been loaded yet, the audio signal received by the tuner unit 11 is output, or the reproduction is performed from the compact disc. The overall operation is controlled so as to output an audio signal. In this case, the system control circuit 12
As shown in FIG. 4A, the name of the source currently being processed is displayed on the liquid crystal display panel 3.

In this state, the system control circuit 12 proceeds to step SP3, determines whether or not the recording operation element 6 has been pressed. If a negative result is obtained here, the system control circuit 12 proceeds to step SP3.
Return to 2. On the other hand, if the recording operation element 6 is pressed, the system control circuit 12 proceeds to step SP4 when a positive result is obtained in step SP3, and determines whether or not a mini-disc serving as a recording medium is loaded. Judge.

If a negative result is obtained, the system control circuit 12 proceeds to step SP5 and starts measuring the time after the recording operation element 6 is pressed by the built-in timer. Subsequently, the system control circuit 12 proceeds to step SP6
Then, as shown in FIG. 4B, a message to the effect that the minidisk is not loaded is displayed on the liquid crystal display panel 3 in addition to the name of the source currently being processed.

Subsequently, the system control circuit 12 proceeds to step SP7 and determines whether or not a recording medium is loaded. If a negative result is obtained here, the system control circuit 12 proceeds to step SP8. Here, the system control circuit 12 determines whether or not the time measurement result by the timer has passed a predetermined time. If the time measurement result is equal to or shorter than a predetermined reference time, the process returns to step SP6. Here, the predetermined reference time is:
For example, it is set in the range of 10 to 30 seconds.

Thus, when the recording operation element 6 is pressed, the system control circuit 12 continues the processing of the source currently being processed and waits for the loading of the mini-disc.

When a mini disk is loaded in this state,
The system control circuit 12 obtains a positive result in step SP7 based on the notification from the mini disk unit 14, and proceeds from step SP7 to step SP8. Here, the system control circuit 12 sets the operation mode of the mini disk unit 14 to the recording standby state. In this case, the mini disk unit 14 accesses the management data recorded on the innermost circumference of the mini disk when the mini disk is loaded, detects the recordable area of the mini disk, and places an optical pickup in the recordable area. , And the track jump is repeated, thereby waiting for a recording start instruction.

Thus, when the mini disc is loaded after the recording operation element 6 is pressed, the system control circuit 12 stops the switching of the source and waits for recording by the previously selected source. Is formed.

In response, the system control circuit 12
As shown in FIG. 4C, the source name of the recording target, the source name of the mini disk, and the recording time are displayed on the liquid crystal display panel 3.

When the operation mode is set to the recording standby in this manner, the system control circuit 12 proceeds to step SP10.
And starts recording on the mini-disc in response to the user's operation. That is, when the recording operation element 6 is pressed again, the system control circuit 12 instructs the mini disk unit 14 to start recording, and thereafter, when the recording operation element 7 is pressed, recording is stopped. After controlling the operation of the mini disk unit 14 so as to stop, the process returns to step SP2. In addition, the user operates the mode controller 8, “DIS”
In response to the operation of the operating elements 9A and 9B corresponding to the display of "K" and "TRACK", the compact disc unit 13 is driven, whereby all the songs recorded on the compact disc or the songs desired by the user can be miniatured. After recording on the disc, the process returns to step SP2.

On the other hand, if the mini disc is not loaded even after the predetermined time has elapsed after the recording operation element 6 is pressed, a positive result is obtained in step SP8, and the system control circuit 12 The operation mode set by the operation of the operation element 6 is released and step SP
Return to 2. In this embodiment, the release of the operation mode is executed by switching the display on the liquid crystal display panel 3 to the original display. Accordingly, the system control circuit 12 may, for example, when the recording operation element 6 is pressed by mistake by the user, after a lapse of a predetermined time,
It returns to the original operation mode.

On the other hand, if the recording operator 6 is pressed with the mini-disc loaded in advance, the system control circuit 12 returns to step SP9 directly by receiving a positive result in step SP4. Then, the mini disc unit 14 is set in a recording standby state. In this case, after the mini-disc is loaded and the reproduction of the mini-disc is started by loading-play, a source other than the mini-disc is selected by operating the source selection operators 5A to 5C, and then the recording operator 6 is operated. If a pressing operation has been performed, or according to the above description, step SP10
