Description

[Detailed description of the invention] (Field of industrial application) The present invention is an in-vehicle disk that can reproduce a predetermined disk address according to the distance traveled by the car by storing the mileage and disk address in advance. Regarding a playback device.

(Prior Art) Conventionally, it has not been possible to automatically reproduce the desired contents of a disc depending on the distance traveled.

(Problems to be solved by the invention) With conventional technology, if you want to play a desired song depending on the distance traveled while driving a car, you have to manually select the song each time, which is inconvenient. There was a problem.

(Means for Solving the Problems) In order to solve the above problems, the in-vehicle disc playback device of the present invention includes a memory circuit that stores distances and disc addresses in association with each other, and a distance circuit that detects the distance traveled. The present invention is characterized by comprising a sensor, and a control means for reproducing a disk address related to the distance when the distance detected by the distance sensor matches the distance stored in the storage circuit.

(Function) When a disk address is played back by an in-vehicle disk playback device while the car is running, the present invention combines the distance and disk address stored in association with the storage circuit with the distance traveled detected by the distance sensor. Based on the distance, the contents of the disk addresses can be automatically reproduced in sequence according to the distance traveled.

(Example) Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, in which a keyboard 1 is used to input disc addresses of CD (compact disc) songs, information, etc. corresponding to the distance traveled, and a keyboard 1 is used to sequentially detect the distance traveled. A distance sensor circuit 2 for driving the CD, a control unit (CPU) 3 that controls the drive of the CD and compares the data input by the distance sensor 2 with the data input to the memory circuit, a drive circuit 4 that drives the CD, and a drive circuit 4 for driving the CD. The figure shows a memory circuit 5 for storing the recorded disk address, a CD playback circuit 6, a cassette/radio/CD switching circuit 7, a cassette playback circuit 8, and a radio reception circuit 9.

First, before traveling by car, check the distance to the destination, enter the disk address corresponding to the distance into the memory circuit 5 from the keyboard 1 shown in the figure via the CPU 3, and then adjust the distance sensor circuit 2 to zero. .

Then, while driving the car, data on the distance traveled from the starting point is input to the CPU 3 by the distance sensor circuit 2 attached to the wheel. The CPU 3 compares the distance data inputted from the distance sensor circuit 2 with the distance data inputted to the memory circuit 5 before departure while the CPU 3 is driving, and when the two data match, the memory circuit stores the data corresponding to the matched distance. 5, and sends a signal to the CD drive circuit 4 to search for the disk address from the CD. The CD drive circuit 4 searches for the input disk address input from the CD and reproduces it.
The CD reproducing circuit 6 reproduces the songs, information, etc. in this disc address section.

If the mileage does not match the distance input to the memory circuit 5, or if the disk address section is not being played, the CPU 3 stops the operation of the drive circuit 4 and switches the cassette/radio/CD switching circuit 7.
is operated to switch to the output of the cassette playback circuit 8 or radio reception circuit 9.

When the radio receiving circuit 9 or the cassette reproducing circuit 8 is operating and the distance traveled becomes the distance data input to the memory circuit, the CPU 3 performs the following operations.
The output of the radio receiving circuit 9 or the cassette playback circuit 8 is connected to the cassette/radio/CD switching circuit 7.
A signal is output to switch to the output of the CD playback circuit 6.
At the same time, the CD drive circuit 4 is operated to cause the CD playback circuit 5 to play back a predetermined input disk address section.

(Effect of the invention) As described above, according to the invention, there is a memory circuit that stores distance and disk address in association with each other, a distance sensor that detects the distance traveled, and a memory circuit that stores the distance traveled that is detected by the distance sensor. The in-vehicle disk playback device is equipped with a control means that plays back the associated disk address when it matches the mileage stored in advance in the circuit, so that it is possible to play desired songs, information, etc. according to the mileage while driving the car. When you want to play a song, you have to manually select the song each time with conventional devices, but the disk addresses that are stored in advance in relation to the distance are automatically played in sequence according to the distance traveled by the car. This greatly improves operability.
