JPS6050787A - Operating method of on-vehicle dad player - Google Patents

Abstract

PURPOSE:To allow a driver to decide on whether a loaded disk is a disk ejected in the middle of the last reproduction or not with a voice output without turning his or her eyes from a vehicle running direction by deciding on whether the disk loaded in a player is the disk ejected in the middle of the last reproduction or not, and starting the reproduction at its beginning automatically when they coincide with each other or voicing dissidence for a specific time when not. CONSTITUTION:When the driver turns on an eject button 22b, the player stores RAM32 with disk information consisting of identification data on the reproduced disk and a reproduction interruption address, and ejects the reproduced disk. When a disk is loaded in the player again, a disk sensor 28 detects that and turns on a power switch 20 to start reproducing the loaded disk at its lead-in part 100. The identification data is read out of the lead-in part 100 to decide on whether the data is coincident with the identification data on the disk which is written in RAM32 or not.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of operating a DAD player for a vehicle, and in particular, a method for determining whether or not a disc loaded in the player is the same disc that was ejected during the previous playback. This invention relates to a method of operating a DAD player for a vehicle.

Frontal Technology Digital Audio Disc (DAD) can obtain extremely good sound quality compared to conventional groove-type records or cassette tapes, etc., and has other advantages such as being able to access the desired location on the disc in a short time. Due to these characteristics, development and practical use of vehicle DAD players have been progressing in recent years so that the discs can be played back in cars.

By the way, this DAD player can eject the disc during playback if the player does not like the disc being played. Therefore, it is often the case that the player does not wish to play back the disc that has been ejected in this way even the next time.

However, while the vehicle is running, in order to remove the previously ejected disk from the multiple disks installed in the vehicle, it is difficult for the driver to temporarily remove his/her line of sight from the direction of travel of the vehicle and identify the contents of the disk. It is inconvenient for driving and requires effective measures for children.

Also, if you select the D A D '71/-17 C, -FIT' disk, the pickup used to play back the A will return to its initial position, so if you play the same disc again, it will return to the previous position. The disadvantage is that it is difficult to start the playback from the position where the playback was interrupted.

Therefore, when using the AI) Play 17 for vehicles, playback of the disc will always start from the beginning. Music etc. recorded on ffn <
Therefore, an effective countermeasure was desired.

Purpose of the Invention The present invention has been made in view of such conventional problems, and its purpose is to prevent the driver from taking his/her line of sight from the direction in which the vehicle is traveling if a disc mounted in a player is ejected during the previous playback. If a disc that was ejected during playback is to be played again, playback of the disc is started from the position where playback was interrupted last time. An object of the present invention is to provide a method of operating a DAD player for a vehicle that makes it possible to operate a DAD player for a vehicle.

Structure of the Invention In order to achieve the above object, the method of the present invention writes and stores identification data and a playback interruption address of a digital audio disc that is ejected during playback in a memory, and then writes and stores the identification data and playback interruption address of a digital audio disc that is ejected during playback. determines whether the identification data of the installed disc matches the identification data stored in the memory, and if they do not match, automatically starts playing the installed disc from the beginning of the disc,
In addition, for a certain period of time, the matching platform outputs a voice to that effect and waits for an instruction to eject the station name disc or start playing. When the instruction is given, playback of the attached disc is started from the playback interruption address position stored in the memory.

With the above configuration, according to the method of the present invention,
The disc loaded in the player was played during the previous playback.
It becomes possible to determine whether or not the imported discs match.
