DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a car audio playback control device that systemizes an audio product.

(Conventional technology) As cars have become more prevalent in daily life, the demand for car audio that provides a more comfortable time has increased, and products with high quality and sensitivity are strongly desired.

Here, car audio is a general term for an in-vehicle system that includes a tuner, tape deck, CD player, and other obscene products, from a source reproduction source to speakers. Note that the source playback device section is generally called a car stereo.

By the way, as a recent trend in car stereos, combination car stereos have become mainstream instead of component car stereos. This is due to the development of electronic technology, which has made multifunctionality, high performance, and high density possible.

Here, the term "component car stereo" refers to one in which each part of a tape deck, CD player, tuner, amplifier, etc. is separated, and has a degree of freedom in combination. Furthermore, a combination digital stereo is one in which a tape deck or CD player, a tuner, and/or an amplifier are integrated.

The tuner has changed from mechanical preset memory to a PLL tuner, and manual tuning has been replaced by a low-end tuner. Furthermore, cassette tape decks are now mostly logic-controlled and auto-reverse. There is a growing trend towards higher power amplifiers that can accommodate four speakers, and further electronicization and higher density are progressing.

(Problems to be Solved by the Invention) As described above, the above-mentioned conventional car audio has enhanced functions and the like, and the degree of freedom in creating a system by combining Opsilon products has increased.

(Means for Solving the Problem) In order to achieve the above object, the car audio playback control device of the present invention has the following features: CD playback by the CD playback means, tape playback by the tape playback means, and tuner reception by the tuner reception means. FF/REW detection means for detecting a fast forward or rewind state of the tape reproducing means;
The present invention is characterized by comprising a reproduction control means for causing the CD reproduction means to perform CD reproduction with priority while the fast forwarding or rewinding state is detected by the EW detection means.

(Function) In the car audio playback control device of the present invention,
Since the playback control means causes the CD playback means to play the CD with priority while the FF/REW detection means detects a fast forward or rewind state, it is possible to eliminate a silent state, and It is also possible to save time and effort in switching modes. Furthermore, by setting a CD of your choice in advance, the desired song will be played when the tape is FF/REWed, making it possible to spend your time more comfortably.
