Description

TECHNICAL FIELD The present invention relates to a disc holder that holds a disc and is detachably incorporated in a main body of a multi-disc player.

BACKGROUND ART A jukebox is generally known as a disc player capable of accommodating a plurality of discs and sequentially selecting any of the discs contained therein to enable continuous performance. However, the conventional jukebox itself is so large that it is not suitable for home use.

In recent years, it has been called a digital audio disc (hereinafter referred to as DAD). By recording a digital signal, the amount of information to be stored can be increased as compared with a conventional analog signal-added audio disc, and reproduction. Several types of discs have been developed and are widely used, which generate less noise during recording. Among them, a disc with an outer diameter of about 12 cm, which is generally called a compact disc, is a system for recording and reading a signal by using a laser beam, and it is easy to handle and enables downsizing of the entire disc player. It is a thing. Recently, a multi-disc player has been developed, which is capable of accommodating a plurality of small DADs (for example, 5 to 6) at all times, and which is optimal as a home jukebox for continuously playing these. By the way, the compact DAD has a playing time of 1 hour and can store about 1.5 times as much information as a conventional analog audio disc. for that reason,
For example, six discs can accommodate about 120 songs if the playing time is about 3 minutes, and it becomes easy to cover by genres of preference such as jazz or enka.

The multi-disc player basically has a playing means including a turntable, a pickup, etc., a disc holder which holds the disc and is inserted and mounted in a mounting portion in the player housing, a playing position of the disc in the disc holder, That is, it is provided with a disc take-out and transport mechanism for transporting the disc onto the turntable.

FIG. 6 shows a conventional disc holder. As shown in the figure, the disc holder is provided with a housing 101 in which a disc projecting opening is formed and a swingable center around a pin 102 in the vicinity of the deepest part of the housing, and the disc 103 has a free end. A projecting arm 104 for engaging the outer peripheral portion of the disk to project the disk from the disk projecting opening, and a swing arm provided around a pin 105 so that the free end portion is provided on the outer peripheral portion of the disk 103. A holding arm 106 for engaging and biasing the disc toward the deepest part of the housing 101, and a coil spring 10 as a biasing force imparting means for imparting a disc biasing force to the retaining arm.
7 and. Note that the disc from the housing 101
The protrusion of 103 is performed by pushing the trigger lever 108 in the direction of arrow T to swing the protruding arm 104 via the intermediate lever 109.

In the disc holder described above, the disc 103 in the housed state is always held by the two arms of the projecting arm 104 and the holding arm 106 and by the biasing force of the coil spring 107. Therefore, even if the disc holder is subjected to external vibration, the disc 103 does not move in the radial direction, and the earthquake resistance is good.

However, the mechanism for swinging the protruding arm 104 has a complicated structure in which the intermediate lever 109 and the tregger lever 108 are provided, and since these are provided in the housing, the number of parts is increased. There were problems such as an increase in product cost, a decrease in mechanical reliability, and an increase in size of the housing body.
