[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an audio apparatus in which a recording medium on which music data is recorded is mounted by a slot-in method.
[0002]
[Problems to be solved by the invention]
Audio devices that play music from recording media on which music data such as CDs (Compact Discs) and MDs (Mini Discs) are recorded are conventionally mounted with a tray method and a slot-in method. There is something to do by.
[0003]
In this tray system, a tray on which a recording medium is placed is slidably attached to the audio body between a storage position and a drawing position, and a recording medium such as a CD is placed on the tray drawn from the audio body to the drawing position. Then, the tray is slid to the storage position in the audio body, and the recording medium is mounted at the data reading position.
[0004]
The slot-in method is a data reading position by using a disk roller or the like to pull in a recording medium that is directly inserted into an insertion port provided in the audio body without using a tray for mounting a recording medium like the tray method. This is the method to attach to.
[0005]
In the conventional recording system mounting method in the audio system, the tray system has an advantage that it can be mounted at the data reading position while the recording medium is securely supported by the tray. When installing, it takes time to pull out the tray, and it is necessary to provide a tray and a drive mechanism for sliding the tray, which makes it difficult to apply to portable audio devices. is doing.
[0006]
For this reason, particularly in a portable audio device, a slot-in system that does not require a tray for mounting a recording medium and its driving mechanism is often employed.
[0007]
However, in this slot-in method, since there is no tray for supporting the recording medium, the support state when the recording medium is mounted is unstable. There is a problem that a trouble is likely to occur due to a difference in insertion force or the like.
[0008]
In this slot-in method, if the recording medium is pulled into the audio main body, it cannot be seen from the outside, so that it is not easy to remove it when it is caught in the middle. In addition, the recording medium may be damaged.
