Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a storage position control method for audio media, and particularly to a method for automatically taking out a desired audio medium from a magazine and setting it in a player using an autochanger mechanism. The present invention relates to a storage position control method for audio media in a vehicle-mounted audio device that performs music.

<Prior art> A magazine loaded with a plurality of audio media such as cassette tapes and compact discs is moved to position a designated audio medium at a media ejection position, and then the audio medium is set in a player and automatically played. There are audio equipment with an automatic changer mechanism.

According to such an audio device with an automatic changer mechanism, it is possible to continuously play music recorded on multiple audio media for a long time, and the music can be recorded on the audio media simply by specifying the desired audio media. You can enjoy music.

For this reason, many audio devices installed in automobiles that are forced to drive for long periods of time are equipped with an automatic changer mechanism.

<Problem that the invention is trying to solve> By the way, when you arrive at your destination while driving while enjoying music recorded on an audio medium,
A driver may turn off the ignition switch and leave the vehicle with the audio medium still set in the player. In such a case, if the audio medium is left in the player for many consecutive days on hot days such as summer, the case or cassette half of the audio medium may become deformed by the heat and cannot be removed from the player.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a storage position control method for audio media that can prevent the case or cassette half of the audio media from being deformed by heat and becoming unable to be removed from the player.

<Means for Solving the Problems> FIG. 1 is a block diagram of an in-vehicle audio device equipped with a cassette automatic changer mechanism to which the present invention can be applied.

8 is a tape feed control section, and 19 is a radio receiver.

<Operation> When the ignition on/off detector 12 detects that the ignition switch is turned off, the processor 11 causes the timer 14 to time the ignition off time.

When the ignition off time T exceeds a predetermined set time, the processor 11 inputs a signal to the autochanger control section 16 and causes the autochanger mechanism 15 to change the cassette tape set in the cassette deck. Take it out and put it back into the magazine. If the ignition switch is turned on before the ignition off time reaches the set time, the state selected by the operation panel 13 will be entered (tape play mode, radio mode, etc.).

Further, the processor 11 uses the auto-change mechanism 15 to take out the cassette tape that was set in the cassette deck when the ignition switch is turned off and sets it in the cassette deck when the ignition switch is turned on again. .

<Embodiment> FIG. 1 is a block diagram of an in-vehicle audio device equipped with a cassette automatic changer to which the present invention can be applied.

11 is a processor that performs storage processing and other processing of the cassette tape according to the present invention; 12 is an ignition on/off detector that detects whether the ignition switch is turned on or off; 13 is an operation panel for the audio equipment; 14 is a timer that measures the time after the ignition is turned off; 15 is an autochanger mechanism; 16 is an autochanger control unit that controls the autochanger mechanism; 17 is a tape feed mechanism; and 18 is a tape feed mechanism. The tape feed control section 19 is a radio receiver.

FIG. 2 is a schematic explanatory diagram of the cassette automatic changer, and the magazine 21 has a plurality of cassette storage sections 22a, 22a, . . . , and each cassette storage section stores cassette tapes 23, 23, . ing. This magazine 21 is the guide member 2
4. It is constructed so that it can move along the rolling rollers 25 in the direction of the solid line arrow relative to the cassette deck 26. Although the magazine drive mechanism is not shown, for example, a rack extending along the moving direction is attached to one side of the magazine 21, and a pinion gear driven by a magazine drive motor is engaged with the rack. do.

The cassette deck 26 has a main body 26a and a cassette receiving/discharging port 26b.

Although not shown, the cassette tape is moved in a direction perpendicular to the guide member 24 to move the cassette tape from the cassette receiving/discharging port 26b to the cassette deck main body 26.
a and the cassette tape set in the cassette deck 26 into the set storage section 22a.
A cassette drawer mechanism for storing the cassette in the cassette is disposed opposite the cassette receiving/ejecting port.
(It is located below the magazine 21 and cannot be seen).

Further, although not shown, a sensor is provided which detects each movement of the magazine 21 by one cassette pitch and generates a signal, and the signal from the sensor is used to ensure that a predetermined cassette storage section 22a is correctly placed in the cassette receiving/ejecting port 26b. I am now able to face it.

FIG. 3 is a flowchart of the audio medium storage position control process according to the present invention. It is assumed that a predetermined cassette tape from the magazine is currently set in the cassette deck and is being played.

(1) Processor 11 checks whether radio reception was turned on while the tape was playing, or whether both the radio and tape were turned off.

(2) If the tape is on (in tape mode), tape playback continues.

(3) However, if the radio reception mode is entered, or if both radio reception and tape listening are turned off (audio equipment non-operating state), the processor 11 outputs a control signal to the tape feed control section 18 to control the tape feed. The unit controls the tape feeding mechanism 17 to stop tape feeding, and at the same time, the head base is moved back to a pause state.

(4) From then on, while the tape is playing (step (2)), or while radio is being received or the audio equipment is not operating (step (3)), the processor 11 checks whether the ignition switch is turned off or not. The signal from the off detection section 12 is checked, and if the ignition switch is on, the processing from step (1) onwards is repeated.

(5) When the ignition switch is turned off, the timer 14 is started to measure the ignition off time.

(6) Processor 11 has ignition off time T
It is checked whether or not the time has exceeded the set time _TS , and if T< _TS , the process returns to step (4) and the subsequent processing is repeated. If the ignition switch is turned on before T≧T _S , the processor 11 resets the timer 14 and jumps to step (1), whereupon it will respond to key inputs from the operation panel 13. .

(7) If the ignition OFF state continues and T≧T _S
If so, the processor 11 outputs a control signal to the autochanger control section 16, which controls the autochanger mechanism 15 to take out the paused cassette tape from the cassette deck and replace it with the cassette on the deck. The tape is returned to the tape storage section 22a of the magazine facing the receiving/discharging port 26b (see FIG. 2).

(8) Thereafter, the processor 11 checks whether the ignition switch is turned on again.

(9) Then, when the ignition is turned on again, the deck's cassette receiving/discharging port 26b
The tape storage section 22a of the magazine facing the
Remove the cassette tape from the cassette deck, set it on the cassette deck, and repeat the process from step (1) onwards.

Although the present invention has been described above in the case where it is applied to an audio device with a cassette autochanger mechanism, the present invention can also be applied to audio devices with an autochanger mechanism such as compact disks and other audio media.

<Effects of the Invention> According to the present invention, when the ignition switch is turned off, the ignition off time is measured, and when the off duration time exceeds the set time, the audio medium set in the player is removed. Since it is configured to be returned to the magazine, even if the ignition switch is turned off and the player leaves the vehicle with audio media set in the player, it will be automatically returned to the magazine, thereby preventing the case or cassette half of the audio media from being exposed to heat. It is possible to prevent a situation where the player is deformed and cannot be removed from the player.

Furthermore, according to the present invention, the audio medium is not returned to the magazine unless the off duration exceeds the set time, so even if the ignition switch is repeatedly turned on and off at relatively short time intervals, the audio medium will not be returned to the magazine. The media can be held in the player and played immediately.

Further, according to the present invention, when the ignition switch is turned on, the audio medium that was installed immediately before the ignition switch is automatically set in the player, so that the ignition switch is turned off. The previous state can be restored and the effort required for media selection can be saved.
